WHAT IS TRAUMA?

ThinkstockPhotos-474756253

Sprains and tendinitis in the front line!

Joints are highly sought in daily life and usually put under strain when practicing some sports. Joints may be subject to traumas that may be violent (knocks, shocks), or insidious but repetitive to end up with sprains and tendinitis.

These pathologies constitute the most frequent reasons for consult in common trauma with approximately 6 million consults per year for tendinitis and not less than 6000 consults a day for one ankle sprain (1)!

Sprains and tendinitis are trivial but painful and disabling and must not be neglected. They may cause complications and must be treated appropriately.

What is the difference between a sprain and tendinitis?

  • A sprain is a damage to one or more ligaments in a joint, leading to painful inflammation with eventual swelling (oedema). Ligaments are fibrous structures that maintain the joint by connecting bones resting on both sides. These ligaments are poorly expandable and any forced movement, excessive traction leads to extreme stretching, even a rupture. That is a sprain.
  • Tendinitis, on the other hand, corresponds to damage to the tendon. The tendon connects the bone from a joint to a muscle same as a rope. Its passes on the muscle strength and allows the movement of the joint. A too intense or repetitive effort induces an irritation and inflammation of the tendon. Unlike the sprain which is usually acute, tendinitis is generally progressive. The movement becomes difficult and painful, it’s tendinitis.

Les entorses

Lésions traumatiques les plus souvent rencontrées (2)

Les entorses de cheville, suivies des entorses du poignet et du genou sont les lésions traumatiques les plus fréquentes.

Les signes

 

L’entorse se manifeste par une douleur assez variable, son intensité n’est pas toujours proportionnelle à la gravité. Le plus souvent, un gonflement (œdème) apparaît plus ou moins rapidement au niveau de l’articulation ainsi qu’un hématome, témoins d’une réaction inflammatoire aiguë, importante, au niveau des ligaments.

 

 

 

 

 Qui ?

Du simple faux pas à l’accident de sport, tout le monde peut se faire une entorse. Il existe cependant des personnes prédisposées et des situations à risque.

  • Personnes âgées ou sportives
  • Antécédents d’entorses
  • Faiblesse musculaire, manque d’exercice
  • Surpoids
  • Chaussures inappropriées
  • Terrain accidenté

L’articulation la plus sujette aux entorses est celle de la cheville et 15 à 20% de celles-ci proviennent d’un traumatisme sportif. Viennent ensuite les entorses des genoux et des doigts.


Les soins

Quelle que soit la gravité de l’entorse, les premiers soins restent les mêmes.

Les 1ers gestes 

Afin de limiter les complications, il est recommandé d’adopter au plus vite ce que l’on appelle le « protocole GREC » (pour Glace, Repos, Compression, Elévation) (1) :

  • Glace: appliquer de la glace (poche remplie de glace, “bombe de froid”) tout de suite puis 4 fois/jour pour réduire la douleur et le gonflement
  • Repos : limiter l’activité, s’aider de cannes anglaises s’il s’agit du genou ou de la cheville
  • Elévation : maintenir le plus souvent possible la zone atteinte surélevée pendant la journée et la nuit (coussin sous le matelas …)
  • Compression légère, seulement pour les personnes averties : immobiliser l’articulation par un bandage ou une attelle souple

Faq

1 . Comment éviter qu’une entorse ne récidive ?

Lors d’une entorse, il est toujours préférable de consulter le médecin traitant et de bien suivre le traitement, notamment la rééducation éventuellement prescrite auprès d’un kinésithérapeute. L’entorse entraîne en effet une perte importante de la force musculaire au niveau de l’articulation atteinte En cas d’entorse de cheville, talons hauts et terrains accidentés seront le plus souvent à éviter.

2 . Toute entorse nécessite-t-elle une radiographie ?

Non, pas forcément. Il existe des critères pour réaliser une radiographie. Schématiquement, elle est préconisée avant 18 ans ou après 55 ans, en cas d’impossibilité de marcher ou de douleur à la palpation des os, car l’on doit écarter la possibilité d’un arrachement osseux ou d’une fracture.

Tendinitis

Frequency of localization of Tendinitis

Many parts of the human body may be affected, first of all, the shoulder, elbow (“tennis elbow”), the knee but also the ankle, the hip, the wrist…

Signs

traumatologie2-230x230

The main symptom is pain at affected tendons. Depending on the significance of the lesion, pain may be perceived as a simple discomfort when moving or a constant shooting pain preventing any movement of the affected joint.

Tendinitis is favoured by age, overweight, presence of pre-existing static disorders but also by inadequate working conditions (repetitive heavy load carrying, inadequate technical gestures), excessive sport practice (excessive use of joints)(1).

 

 

When to consult?

Tendinitis is not a matter of urgency, however it may rapidly become disabling to the personal and professional life.

Therefore, do not hesitate to consult when:

    • Pain is persistent and lasts for 2-6 weeks in spite of adequate treatments
    • In case of a tendinitis due to a professional activity: An interview with the occupational doctor is necessary
    • Movement become impossible: There must be a ligament rupture

First acts in case of pain

  • Stop the activity to put your joint at rest
  • Apply cold: Ice pack, “cold spray”
  • Wear light compression stocking if possible to limit tendon elongation during movement: Elastic bandage, kneepad…
  • Take topical analgesics and/or topical anti-inflammatory medicines as the inflammatory component is major.

Medical care

Upon examination, the doctor will try to locate the affected tendon and assess the impact of tendinitis on activities. In some cases, additional imaging tests may be necessary(1). He/she will then prescribe medicinal treatments and/or adequate functional treatments (1).

Faq

1 . What is a tennis elbow?

It is a frequent elbow tendinitis, also called lateral epicondilytis. Contrary to common belief, it is not only related to tennis practice but mostly to professional or domestic activities. It is a tendon inflammation in the vicinity of a small osseous projection of the elbow, occurring after repetitive movements. Prevention is key.

2 . Are work related tendinitis considered occupational diseases?

Yes. They are considered musculoskeletal disorders (MSD) and represent three quarters of occupational diseases! The occupational doctor is present to ensure it is. He/she will reassess working methods; ensure ergonomic workstation and manoeuvres to carry out.

PROCREATION: A COMPLEX PROCESS

What is more essential for a couple than to have a child? Sometimes, an unfulfilled desire…

Fertility varies from one to another and depends on sexual activity: The probability of pregnancy during a menstrual cycle is low, in the range of 20-25% (1). Fertilization, as a prelude to pregnancy, is in fact a complex physiological process that is regulated by multiple factors, including hormonal ones.

Fertility

Fertalization in short

 

ThinkstockPhotos-78617017

Fertilization is the outcome of the encounter between an ovum and a sperm cell, two reproductive human cells. The most favourable moment to this encounter is before the 13th day of a 28-day cycle, which means at ovulation.

Ovulation: The ovum (egg) develops in the ovary inside the “follicle” then released toward the fallopian tube. This process is carried out under the control of brain hormones (FSH and LH); which are themselves influenced by hormones that are secreted by ovaries.

The “encounter”: It happens within the tube, where sperm cells swim up after their release in the vagina. Sperm cells must be in a sufficient large number, mobile and find a favourable milieu in the cervix, notably the mucus; which quality depends on cerebral and ovarian hormones (estrogens and hCG).

Fertilization itself: Only one of these sperm cells will fertilize the egg. An egg-cell is therefore created, it predetermines the embryo. This cell starts dividing and begins its descents towards the vagina.

Implantation: The future embryo reaches the uterus. It implants within the endometrial which is pre-prepared by ovarian hormone stimulation (estrogens then progesterone).

Every step of this process is crucial and any disruption compromises the future pregnancy.


Infertility, a rising concern

 

We speak of infertility when a couple failed to achieve pregnancy after 1 year of regular contraception-free sexual activity. According to the Epidemiological Observatory of Fertility in France, this is the case of 18-24% of couples after one year of trial. After two years, couples who are still waiting to get pregnant are 8-11% (1). This number is gradually increasing.

Increasing older reproductive age

In France, couples decide more and more to have a child at an older age. The mean age of the first pregnancy increased from 25.1 years old between 1980 and 1984 (2) to 30 years old in 2011 (3). However, this increase in age is detrimental to fertility. After 38 years old, the egg cells stock begins to run out and egg cells have a less good quality.

Decline in the quality of sperm

A constant decline in the quality of sperm is also observed (number and/or mobility of sperm cells). The quantity of sperm cells decreases from 443.2 to 300.2 millions in 34 years (between 1976 and 2009). Actually, numerous factors have been implicated, notably environmental pollutants such as heavy metals and some organic pollutants (PCB…).

From now on, contrary to conventional wisdom; infertility involves men as often as women.

Origins of infertility – WHO study (4)

In 5% of cases, this infertility remains unexplained, no causes haven been found (4).

Causes of infertility

 

There are many causes, sometimes hard to detect and often requiring thorough additional tests during diagnosis.

In women

Ovulation disorders are the main cause of infertility: Ovulation may be irregular (dysovulation) or totally absent (anovulation). Some of these anovulations are related to a polycystic ovary syndrome.

Distribution of the main causes of female infertility (1)

 

We also find:

  • Fallopian tube damage: Blockage or damage, secondary to an infection (salpingitis), a congenital anomaly…
  • Endometriosis: Pathological presence of endometrial glands outside of the uterus (in the ovaries, tubes, peritoneal cavity…)
  • Infertility related to abnormalities of the cervix and its secretion
  • Hormonal disorders, such as thyroid disorders, or uterine anomaly or pelvic abnormality, fibroma, polyps…

In men

Here again, there are many causes:

  • Changes in the number, mobility and/or morphology of sperm cells
  • Hormonal disorders such as male hormone deficiency
  • History of trauma, surgery or infections
  • Retrograde ejaculation, varicocele (dilated veins within the testicles)
  • Genetic disorders, birth defects…

Between couples

Some behaviours or lifestyles are also harmful to the occurrence of a pregnancy: Tobacco, excessive alcohol, overweight, few or outside fertile period sexual intercourse, or even simply and unfortunately, being afraid …. of not having a baby!

Management: first steps

 

Infertility evaluation

Medical tests are usually prescribed after a period of 18-24 months of unsuccessful sexual activity for a young couple without any known risk. For older couples, or couples with a history of eventual insufficient fertility, it is recommended to do the tests starting from the 6th month. It specifies the cause or causes of infertility relying, if needed, on additional tests that involve both partners (spermanalysis for men and hormonal examination for women). The outcome of these tests allows drawing a number of therapeutic solutions for the couple. Most of them are medical or surgical. If a major infertility is detected, the couple is referred straightaway to a center for assisted reproduction.

Initial medical treatments

The most frequent treatment of infertility is ovarian stimulation. It consists in stimulating the ovary with hormonal treatments (anti-estrogens or hormones such as FSH, usually secreted to stimulate the ovaries). We therefore obtain a simultaneous development of many follicles, each containing one egg. When the development is deemed satisfactory, ovulation is triggered by an injection. Other treatments (anti-infectives, etc.) are also prescribed according to an individual assessment, sometimes with vitamin supplementation (vitamin B12 and folic acid), notably in women with polycystic ovaries.

Reproduction surgery

In women, it is first of all a surgery of fallopian tubes. We can also remove endometrial lesions, pelvic adherences, polyps… in men, surgery mainly applies in case of atrophy of vas deferens or some important varicocele.

Assisted reproduction

 

Assisted reproduction or medically assisted procreation (MAP) consists in reproducing part of the natural process of fertilization, in a laboratory. Several techniques exist, each with precise indications. They allow considering serenely having children even in case of infertility.

Artificial insemination

It consists in collecting and preparing the spouse’s sperm to inject it in the woman’s uterus at the time of ovulation, most often after ovarian stimulation. Fertilization then occurs naturally, inside the woman’s body.

In vitro fertilization (IVF)

Eggs are obtained after important ovarian stimulation (FSH). Eggs are harvested then placed in culture, in contact with the spouse’s sperm cells harvested the same day.

fiv_endocell

1- Ovarian stimulation and ovarian puncture for oocyte retrieval

2- Putting sperm cells with oocyte for fertilization

3- In vitro development of the embryo

4- Embryo(s) transfer into the uterus

 

Embryos will then develop for 48 hours or even 5 days (what is called extended culture). They are then transferred into the womb for implantation.

Sperm microinjection

It involves the direct injection of sperm into an egg, instead of waiting for spontaneous fertilization to occur, just like in IVF. The other steps are identical to those of an IVF, from ovarian stimulation until embryo transfer.

Lastly, anonymous donations of embryos or gamete (oocyte and/or sperm) may be a last resort.

Nearly 3% of children are born today this way by MAP in France in 2012 (1).

Faq

1 . In case of problems conceiving, is it possible to discuss it with the treating physician?

Of course it is, he/she is the first contact, especially when not followed by a gynaecologist. The general practitioner is perfectly qualified to confirm the infertility of a couple after a thorough interview, and if necessary, simple tests: Temperature curve, hormonal determination, ultrasound for women, sperm count for men.
Depending on the outcome, he/she may refer to a specialized gynaecologist in the fertility field.

2 . Where is IVF performed?

IVF, as any other assisted reproductive technology (ART), is performed at an authorized center, with accredited medical and technical equipment. These centers may be located in hospitals or clinics.

3 . What exactly is the syndrome of polycystic ovaries?

It’s a rather frequent hormonal abnormality, affecting 10% of women. It is responsible for the absence of ovulation and an irregular cycle. It also occurs with an overweight or obesity, acne, excessive hair growth...
Causes are not precisely known, however, when a couple wants to have children, ovarian stimulation generally helps regaining ovulation.

WHAT IS OSTEOARTHRITIS?

Osteoarthritis is a degenerative chronic condition, a form of rheumatism that progressively destroys the cartilage that covers the bones of some joints. It leads to a handicap with difficulties to move.

Osteoarthritis

Pain usually reveals osteoarthritis, otherwise, it goes unnoticed.

 


Main locations

Osteoarthritis mainly affects the joints of the knees, fingers, hips and cervical lumbar spine (1).

 

It may also affect the spine (cervical, lumbar vertebrae…), ankle, shoulders…

In general, several joints may be affected. We generally use the term generalized osteoarthritis when more than 3 joints are affected.

Osteoarthritis is the most common joint disease

Today, osteoarthritis affects nearly 10 million people in France: one French out of 6. It is one of the primary causes of invalidity in developed countries (1) and its frequency increases with age, despite the existence of juvenile forms. With the increase of elderly population and the expected doubling of the number of new cases by 2030; osteoarthritis is considered a true public health challenge.

Beyond the pain, this benign disease causes the loss of freedom of movement in time limiting progressively the mobility of affected joints. In 2005, osteoarthritis represents the second cause of invalidity in France, after cardiovascular diseases (2).

Clinical symptoms of osteoarthritis

ThinkstockPhotos-78738981

Pain is generally a revealing sign of osteoarthritis; being its main symptom. At the start of the disease, the pain is mechanical and marked by effort: It appears and deteriorates with the mobilisation of the affected joint and eases when rested.

In some people, a more or less long phase of stabilization may appear. However, osteoarthritis inevitably progresses.

The progression of osteoarthritis may also be associated with inflammatory outbreaks characterized by even painful swelling for a few days. In this case, pain persists at rest and may cause nocturnal awakening.

 

How is osteoarthritis diagnosed?

The treating physician will first ask about specifics on the pain characteristics, sensation of stiffness, and disruption of everyday life…. He/She will search for the presence of a reduced joint mobility, deformations, swelling.

He/She will rely on lab analyses and x-rays for more specifics, if necessary (presence of bone excrescence, narrowing of the joint space…)

He/She may ask for a rheumatologist or an orthopaedic surgeon opinion at an advanced stage.


Risk factors

Age is the first enabling factor but it is not the only one. Other factors are now well identified:

  • Gender: Osteoarthritis is more frequent in women than in men and its frequency dramatically increases after menopause, especially osteoarthritis of the knees and fingers. Thus, osteoarthritis at the base of the thumb (carpometacarpal osteoarthritis) mainly affects women (80-90% of cases) and increases from 8% of women before menopause to 25% after.
  • Genetics: Osteoarthritis runs in many families due to its inheritance nature (1). 
  • Traumas or repetitive strains: In case of high level sport activities or jobs exposed to repetitive violent movements or vibrations (pneumatic drills for miners, drillers…)
  • Overweight: Overweight is responsible for overload on the knee joints (gonarthrosis). In women, obesity may multiply the risk of gonarthrosis by 9 especially through hormonal factors.
  • Certain anatomic abnormalities: By modifying the normal weight borne by joints; some cartilage areas are overburden.

 

Osteoarthritis is therefore multifactor disease. Causes are complex and some of them, still little known, are still under investigation: Diabetes, hypercholesterolemia, hypertension…

Treatments

 Management of osteoarthritis targets on one hand pain relief, the most afflictive symptom, and on the other hand it limits its progression and the subsequent disablement that it creates. For this reason, experts recommend the combination of medical and non medical treatments and to individualize the treatment to each patient (1).

Thus, in case of pain, we usually prescribe analgesics or anti-inflammatory medicines (paracetamol or oral anti-inflammatory drugs for a short treatment period to limit digestive adverse events that are sometimes serious). These treatments are nowadays combined with more specific medicines for osteoarthritis called “anti-arthritics”.

Lifestyle is also a core part of the treatment and complement medicine-based treatments. Lifestyle maintenance is recommended by doctors in accordance to each patient way of life and needs: Possible reduction of overweight, regular physical activities during off periods of inflammatory outbreaks, physiotherapy, use of orthesis, use of canes…

 The earlier this management occurs; the better controlled the progression of osteoarthritis. Therefore, it is better to consult your doctor upon the first signs as he/she will be the best to develop a global strategy.

Faq

1 . Is osteoarthritis inevitable?

Today, we can slow down the progression of the disease. An early screening will help implement an adequate treatment upon the first signs of the disease: Prevention of risky practices and appropriate medicinal treatments, particularly with new molecules specifically conceived for osteoarthritis.

2 . Is it hereditary?

Yes partly, at least for the osteoarthritis of the knee (gonarthrosis), hip (coxarthrosis) and above all the osteoarthritis of the fingers. Thus, women are more at risk to develop osteoarthritis of the hands if their mother or aunt is affected by one.

3 . Is sport a risk for the joints?

It depends on its intensity. A moderate sport practice is not responsible in itself for arthritic lesions. However, high level violent or intense sports may cause a harmful overload on the joints: Rugby, football (soccer), downhill ski, combat sport or more...dance could in the long run cause osteoarthritis of the knees.

4 . What about joint infiltrations?

Intra-articular infiltrations are particularly useful during very painful inflammatory outbreaks. This technique is performed by rheumatologists, functional rehabilitation specialists and orthopaedic surgeons. It ensures long lasting improved effectiveness (corticoids or hyaluronic acid).

WHAT IS SKIN?

Skin is the largest organ of our body. Its thickness varies depending on the different areas in the body from some tenth of millimetres in the eyelids to near 6 mm in the back.

The main role of the skin is to protect our organism from external aggressions, acting as a barrier. It also plays a major role on other vital functions, such as perception (touch), immunity, body temperature preservation as well as vitamin D synthesis.

The skin of our face is very sensitive and exposed to external aggressions. Daily care is essential and contributes to maintain appearance and health.

Healing

How does the skin heal?

 

Like all organs, the skin is equipped with repair and renewal capacities that help it heal: more or less rapidly and not always true. It all depends on the extent and depth of the injury.

The skin has three superposed layers: The epidermis at the surface, below there is the dermis which is rich in nourishing blood vessels and nerves, all located within a collagen and hyaluronic acid structure. Finally, in depth, there is the hypodermis.

If the injury is superficial and does not affect the epidermis, then the skin is able to renew itself provided causes of irritation are eliminated.

When the injury is more important, deep structures of the skin may be affected and the body unleashes a different cascade of reactions:

  • Blood coagulates to stop bleeding, a blood clot forms.
  • Defence cells called macrophages absorb eventually present debris and microorganisms to clean the injury: It is called the cleansing phase. During this phase that may last from a few hours to 4 days, the wound exudes colourless to slightly yellow liquid, called lymph, containing cleansing and stimulating substances that favour the emergence of vessels. The healing process has begun.
  • To make up for the wound-induced loss of substance, the proliferation phase sets in. A new support tissue is constituted with collagen and hyaluronic acid synthesis by cells from the dermis. New vessels are created. This tissue proliferates to the surface of the skin.
  • When this tissue sufficiently fills in the wound, the epithelium of the adjacent intact skin colonizes the surface of the wound. At the end of ten days, the crust falls to reveal a scar.

This natural healing process may be compromised by different factors, either the presence of foreign bodies, important hematoma, infection, and underlying disease but also by inadequate care.

 


Daily life wounds

 

ThinkstockPhotos-179845691

Cuts, scratches, abrasions by a rough surface…small wounds of everyday life may seem harmless but they must be adequately treated to heal well, without any risk of infection.

First acts

  1. Compress the wound until the bleeding stops.
  2. Use physiological serum to clean; or in case of heavy contamination, you may first wash the affected area with soap and water (1). If too painful, do not insist.
  3. Protect the infection using an antiseptic, preferably colourless, to mask the progression of the wound. Avoid using alcohol.
  4. if needed, apply a bandage: Sterile gauze, sterile compress or pre-cut bandage.

In addition to classic bandages, there are more specific bandages (watertight, humid, hydrocolloidal…) as well as creams and healing compresses. Ask your pharmacist for advice.

Whatever the type of the wound, one must always check if anti-tetanus immunization is up to date.

When to consult?

  • In case of any doubt for children and elderly and systematically for newborns.
  • In case of extended wound, more than half the surface of the palm, or if very contaminated by foreign bodies.
  • When the wound is located on the back of the hand, on the neck or near a natural orifice such as the eyes which are risky areas.
  • In case of a disease that further weakens the victim: diabetes, corticoids treatment or anti-coagulants…
  • In case of signs of infection: swelling, oozing, purulent drainage.
  • If bitten by an animal or crush injury.

Les brûlures

 

In everyday life, there are plenty of opportunities to get burned. Burns may be due to heat (90% of burns) and also to sunlight (sunburns) and rarely to electric current or a chemical product.

Mains causes of burns (1)

While little burns can be easily healed, more extensive or deep burns require immediate consultation.

Different types of burns

To assess their seriousness, burns are classified depending on their extent and depth:

  • First degree burns: Only epidermis is affected. The skin is red, painful, even swollen. It’s the standard “sunburn” or a kitchen burn.
  • Second degree burns: Dermis is affected. Very painful, the skin is pinkish and humid, blisters appear.
  • Third degree burns: The affected area is deeper. The skin is usually white but may be brown or even black. Ironically, there is little or no pain because the nerve ends have been destroyed.

What to do?

When the burn is superficial, the extent is less than half the palm of the victim’s hand and is not located near a natural orifice, topical care is sufficient.

First degree burn

  • Cool down the burn by splashing fresh water for at least 5 minutes. This limits the progression of lesions;
  • Apply an antibacterial-free hydrating cream or ointment (2). There are burn specific creams and ointments. Ask your pharmacist for advice.

Little extended second degree burn

  • Do not cut through the blisters as they protect from infections and reduce the pain;
  • Wash with fresh water;
  • Disinfect the wound with an alcohol-free antiseptic as there is a risk of infection if blisters are cut;
  • Protect the wound using specific bandages “non adhereing wound dressing” type, “membrane dressing” type or with antibacterial ointments or bandages (2).

Consult your doctor in case of any doubt or in case of more extensive burn. In case of serious burn, call SAMU/Center 15.

Leg ulcers

 

Poor blood circulation, either due to venous insufficiency or atherosclerosis, leads to complications including leg ulcer. It is defined as a wound, a loss of substance affecting the skin up to the dermis, particularly difficult to heal with a risk of infection.

Signs

Ulcers of venous origin, by far the most common (80% of leg ulcers), represent a very progressive stage of chronic venous insufficiency (varicose vein, or more frequently, history of thrombosis). It appears progressively, most often within the ankles, and is generally not painful. Which is the entire issue! In absence of treatment, the ulcer becomes chronic. One should always check any wound in the leg.

Arterial ulcer is less frequent and rather affects men aged over 50 years old with vascular risk factors (tobacco, hypertension, obesity…). Unlike the previous, it appears brutal, mostly after a shock, and is very painful.

In both cases, immediate consultation is advised.

Medical care

To heal a leg ulcer, it is not enough to just treat the wound, one must also treat the cause.

The wound will be cleaned; residues that are hindering the healing process will be removed. Conducive local conditions will then be restored using bandages that adapt to each healing phase. After the detersion phase, interface, hydrocellular, hydrocolloidal, Vaseline or hyaluronic acid containing dressings will be used.

In parallel, what caused the ulcer will be treated. If it is of venous origin, a venous contention will be positioned using specific dressing. In case of arterial ulcer, the patient will be advised to limit the cardiovascular risk factors (tobacco, arterial hypertension, overweight…).

Wounds and diabetes

 

People with diabetes know the attention they should pay, particularly, to their feet. Because a poorly controlled diabetes exposes the patient to healing difficulties in case of injury, even in case of a wound that went undetected for a very long time. Eventually, there is a risk of amputation.

Globally, 15% of diabetic patients will present a foot ulcer at one moment of their lives (1). An old or a poorly controlled diabetes may, in fact, cause a loss of sensitivity within extremities which favour the occurrence of injuries as well as vascular disorders that are detrimental to healing, with an increased risk of infection due to the decrease in immune defences.

More worryingly, some wounds may pass completely undetected. It’s the case of the “diabetic foot ulcer”, ulceration at the sole of the foot which is luckily increasingly rare, is deep and painless and may progress undetected. This is why it is advised to daily inspect the feet of a diabetic person with regular visits to the chiropodist (1). Consultation is required even with the smallest injury!

Medical care

Within the wound, the best possible conditions are to be established to help the healing process. This is achieved by dehorning (horn removal) and debridement around the wound using a lancet, then application of a bandage specific to each healing phase. After the detersion phase, interface, hydrocellular, hydrocolloidal, vaseline or hyaluronic acid containing dressings will be used to significantly reduce the size of the ulcer.

On a general level, controlling diabetes is imperative to heal. In case of diabetic foot ulcer, the foot will be strictly and permanently offloaded until healing, ideally with suitable shoes.

Cracks and infant diaper rashes…

 

Cracks

Cracks are skin injuries that are due to severe drought and repetitive aggressions by the cold, irritant products (detergents), intensive pressures (foot cracks) or repetitive micro-trauma (cracked nipples when breastfeeding). Usually shallow, they must be treated in time to avoid exacerbation and pain.

The solution: Regularly hydrate the skin.

There are a number of hydrating creams. Some are specifically formulated without aggressive components (perfume, conservatives…) to respect fragile skin. They hydrate, relieve and favour skin repair.

Infant diaper rash

Diaper rash is an irritation that alters the superficial layer of the skin. It is localized in the areas that are covered by diapers (bottom, genitalia, and inner thighs) and is displayed by a dry or exuding redness, with or without small spots. In most cases, it is due to the rubbing of diapers against the skin, diapers that are too tight or not enough changed. Contact with urine and faeces also cause a chemical “burn” that is increased if the baby suffers from diarrhoea. The natural protection that is ensured by the skin is disrupted and must be re-established as soon as possible to limit the risks of infection.

What to do?

Avoid all sources of maceration of the skin by leaving the baby diaper free whenever possible. Apply a soothing and protecting cream after every nappy change: Zinc oxide, copper sulphate, dexpanthenol based creams or healing care products that are conceived to repair as soon as possible the weakened skin of the baby. Ask your pharmacist for advice.

Dermatosis (dermatitis, psoriasis, vitiligo)

Dermatitis

Dermatitis is characterized by intense itching and is one of the most frequent skin diseases responsible for nearly 30% of consults in dermatology. It’s a chronic inflammatory disease of multiple origins including allergy being the main cause. It is characterized by the presence of poorly defined red plaques, sometimes associated with small transparent blisters that may converge in bubble, break, and seep then form a crust.

There are two major types of dermatitis.

Contact dermatitis

It is only observed when there is contact with substances –so called allergenic – i.e. causing an allergic reaction. These substances may vary from one person to another: medicines, hair dyes, plastic (latex gloves), metals (earrings)…the doctor will use skin tests to identify which substance causes the allergy.

Atopic dermatitis

Atopic dermatitis is determined by a hereditary predisposition to develop allergic reactions associated with a genetic abnormality which renders the skin “permeable” to some substances. This is the case of some food among infants and substances in the air among older (pollen, dust mite…).

Main localizations of dermatitis:

  • cheeks
  • elbows
  • forehead
  • knees

 

eczema-bebe

 

Atopic dermatitis progresses naturally with age:

  • In infants, flare-ups are frequent and are essentially present in the cheeks and forehead;
  • After the age of 2, the dermatitis become more chronic, it rather affects the skin folds (elbows, knees); as a result of scratching, the skin becomes dry and thick.
  • Dermatitis declines in 85-90% of cases in adolescents and adults.

Psoriasis

 

Psoriasis is a skin disease characterized by red plaques covered by dead skin, dandruff that gets loose easily. Psoriasis is neither infectious nor contagious; in most cases, it is benign but may prove to be particularly inconveniencing in case of visible lesions. Psoriasis is relatively frequent affecting nearly 2% of the population (1,2). It affects both children and adults with two peaks of frequency: around twenty (young adult) and around fifty.

Specific localizations

It is a chronic disease that progresses with inflammatory flare-ups. There are many types of psoriasis. The most common is plaque psoriasis. Plaques are little widespread; well defined with some itching. They are most often localized symmetrically within areas that are exposed to contact (elbows, knees, anterior surface of tibias, sometimes in the scalp and lower back).

Main localizations of dermatitis:

  • elbows
  • knees
  • tibias

 

psoriasis

 

Other types are rarer, such as the guttate psoriasis, with drop-like lesions separated and dispatched all over the body. In a certain number of cases (2), psoriasis may be complicated with the occurrence of a joint damage called psoriatic arthrisis.

Very fast cellular renewal of the epidermis

Psoriasis is caused by a cellular renewal of the superficial layer of the skin that occurs too fast, thus building up and forming plaques. Two factors come into play in the occurrence of flare-ups: a hereditary predisposition combined with triggering factors such as an infectious disease, intake of some medicines, stress or even repetitive trauma on the skin (rubbing of clothes)…

Psoriasis is an unpredictable progressive chronic disease that requires medical attention.

Treatment of dermatitis and psoriasis

 

Presently, dermatitis and psoriasis, which are both chronic inflammatory disorders, can be considerably soothed. A wide range of treatments may in fact soothe the symptoms and reduce the visibility of lesions, thus improving the quality of life.

For these skin disorders, precedence is given to local treatments. They are based on local application of corticoids, called dermocorticoids (1,2). Their effect is usually spectacular on both lesions and itchings. They exist in different forms, prescribed depending on the nature and localization of plaques: ointment, cream, gel, lotion or even medicated plasters. Other treatments may be associated to reduce the thickness of plaques or heal a possible secondary infection… in case of intensive itching, oral antihistamines are prescribed. More intensive treatments, such as immunosuppressant, are reserved for serious disorders.

Phototherapy using UV light may also be useful for certain people. It is prescription-only and practiced only by a dermatologist.

How to protect the skin on a daily basis?

These disorders are characterized by a skin that is too dry and uncomfortable, with pulling. Protecting the skin is an essential part of the treatment:

  • Hydrating the skin with bath oils, lipid-enriched soaps and emollient creams. Avoid the use of classical soaps.
  • Do not scratch the lesions. In case of itching, simply press on the “scratchy” area.
  • Avoid too tight clothing, synthetic materials and wool. Favour cotton and linen.
  • Use soft detergents when washing clothes.

Vitiligo

 

White spots, smooth, sometimes with a certain relief… these are the characteristics of vitiligo, a chronic skin disorder, benign, painless and non contagious but often hard to live with because of an esthetical prejudice.

Characteristic white spots

Vitiligo appears in 50% of cases between 10 and 20 years old (1), but mainly between the age of 20 and 30. Depigmented white spots or plaques appear anywhere on the body but there are preferred areas: Back of the hands, feet, elbows and knees, areas located in the folds of the skin… the number of spots is variable, two to three small spots or wide plaques on the entire body. The progression is unpredictable; vitiligo may widen or rarely, repigment itself spontaneously, especially in sun-exposed areas.

A melanocyte failure

Vitiligo is due to a local loss of melanocytes*, cells that colour and pigment the skin. Precise cause of their loss remains unknown until today. Inheritance definitely plays a role: In nearly 30% of cases, there is a family history. Immune disorders are also responsible: called an auto-immune disorder, which means a disease in which the immune system, usually destined to fight micro-organisms from the outside, will make a mistake on the enemy and destroys wrongly the melanocytes of the skin (1).

The specific cause of vitiligo is therefore unknown, but there are triggering factors that favour the occurrence of plaques: overexposure to the sun, stress, local micro-trauma within rubbing areas of the skin, such as hands, elbows and knees.

 *melanocytes are cells that pigment the skin

Treatment of vitiligo

 

Actual treatments help reduce the size and the number of spots or to repigment the skin by giving back a coloured appearance.

When spots are recent and remain localized, it is possible to stimulate the production of pigments by melanocytes that are still present using local corticoids called dermocorticoids. Best results are obtained on the skin and neck, with recent lesions and dark skins (1). These skin repigmentation solutions (dermocorticoids) may be associated with immunomodulators** that also contribute to skin repigmentation.

Phototherapy, using UV light, is practiced in children and people suffering from generalized vitiligo or people who are treatment resistant to previous therapies. More recent, laser targeted phototherapy appears efficient and well tolerated.

When the outcome is not possible with repigmentation treatments, one might consider a menalocyte transplantation. The transplantation allows implantation of melanocytes taken from the patient itself on the depigmented area. The last evolution of this technique consists in implanting melanocytes in suspension and provides efficient outcomes (2).

**medicine that stimulates or represses the immune system reactions

How to limit the spots?

While waiting for the outcomes of medical treatment, self-tanning creams or special colour correction may be used to camouflage patches.

Although the sun has renown skin pigmentation virtues, it may only be used in the controlled framework of a heliotherapy*** prescribed by a doctor. In other cases, it is essential to protect the very fragile pigmented areas: sunscreen and covering clothes are necessary even in winter or cloudy weather.

Faq

1 . In case of dermatitis in children, are there any food precautions?

If the paediatrician diagnoses a food allergy, he/she will prescribe a diet excluding the food item or the components identified during skin tests.
If the child presents an atopic environment without identified food allergy, the doctor will simply delay the introduction of the most allergenic food (cow milk, dairy products).
Children cannot follow a diet without a doctor’s advice as this will expose them to nutritional deficiency.

2 . Are dermatitis, psoriasis and vitiligo of psychosomatic origin?

It depends on the disorder. If it’s dermatitis or psoriasis, the beneficial effect of the sun is recognized provided it is used with moderation. Whence, the origin of phototherapy.
However, in the case of vitiligo, depigmented white patches are particularly sensitive to the sun as they are deprived from melanine, the pigment produced by melanocytes to protect the skin. The sun is therefore an enemy and one must protect himself.

3 . What is done in research for vitiligo?

Genetic research progresses with the recent discovery of the genes that are involved in auto-immune diseases. However, surgical treatments are the most tangible in terms of progress with the melanocyte transplantation technique. The last evolution of this technique consists in implanting melanocytes in suspension and provides simple and efficient outcomes (1).

Skin aging

The skin and its components

The skin is sensitive, reactive, and emotional when it flushes or blushes. It reflects our emotions, our vitality and our age, with the passage of time.

To ensure its multiple functions, first protect us from knocks, wounds and microorganisms, our skin is composed of three layers:

  • The epidermis at the surface: covered with a protective corneous layer riddled with sensory nerve endings. It is water repellent due to sebum, a lipid rich substance, and equipped with cells producing melanin, a pigment that protects from the sun.
  • The dermis located under the epidermis: it is a support structure armed with collagen and elastin fibers bathing in a proteoglycan gel. It contains all necessary structures for the skin functioning: blood vessels, hair follicles, sweat glands, sebum producing sebaceous gland and fibroblasts secreting the fibrous framework and hyaluronic acid.
  • The hypodermis in depth: thermal isolator enriched in fatty energetic reserves.

Essential components for skin tone

  • Derm’s collagen: Collagen fibres are linked together by elastin filaments and constitute a true framework for the skin to make it resistant to blows and shocks.
    • It ensures tone and resistance
  • Hyaluronic acid: It is inserted between collagen fibres with excellent hydrating properties as it retains 1000 times its weight in water and creates a hydrated and plump “mattress”.
    •  It procures flexibility and hydration
  • Antioxidants are present in all skin cells: They maintain the skin integrity by neutralizing free radicals. Free radicals are toxic components arising from cellular metabolism and external aggressions (sun, infections, inflammation…). If not neutralized, they destroy all surrounding structures. Today, they are the sole responsible for aging.

To trap these free radicals, our nutrition provides us with natural antioxidants.  They constitute the main defence against aging.


With time, the skin gradually loses its tone, and starting from the age of 30, the first lines appear.

At the surface, the epidermis becomes thinner and does not regenerate fast enough. Sebum secretion decreases and the skin become dryer.

The dermis becomes also thinner. Its cells with collagen, hyaluronic acid and elastin secretion and renewal properties become less performant. The synthesis and the quality of these essential components diminish, the framework of the dermis becomes less organized and the hyaluronic acid mattress “deflates”. The skin gradually loses its tone, its flexibility and volumes.

Then wrinkles deepen, the skin becomes loose and the facial outline becomes saggy.

This natural aging process is controlled by genetic and hormonal factors and is inevitable. For example, at menopause, it increases following the decrease of oestrogen secretion.

Skin aging can however significantly increase under the effect of external and environmental factors which we can fortunately fight!

EXTERNAL AGGRESSIONS

  • Sun: Favours the formation of numerous free radicals that attack skin cells and cause premature death.
  • Tobacco: Shrink the diameter of the small vessels that nourish the skin and supply it with micro-nutrients thus weakening them.
  • Stress: Increases the production of free radicals.
  • Air pollution: Decreases the immune system defences.
  • Unbalanced diet, low in fruit and vegetables: If antioxidant intake is insufficient, free radicals will target cell membranes, degrade collagen and hyaluronic acid.

A certain healthy living sensitively decreases the effect of environmental damaging factors such as the use of daily protective cosmetic care products.

 

 


Daily care

ThinkstockPhotos-78618774

Cosmetic care products are essential everyday to maintain the skin in good health as they contribute to delay the emergence of aging signs; they also protect the skin against external aggressions by reducing them.

Most act on the superior layers of the epidermis but there are substances that act deeper to increase the soothing of the skin. Some substances are able to re-stimulate the synthesis of the major components of the skin and to favour the renewal of fibroblasts (hyaluronic acid, collagen…) (1). These substances may be associated to antioxidant ingredients that act against premature aging (coenzyme Q10, antioxidant flavonoides, plant extracts, vitamins C and E…).

Food suppléments

They reinforce the anti-aging effect of skincare products, provided a formulation that suits the skin needs. They should therefore offer antioxidants and ingredients that nourish the dermis as well as, ideally, rejuvenating active substances. Their effect is optimal when used daily, in combination with suited skincare products.

Medical and surgical treatments

 

Aesthetic medicine

It tackles mainly deep and tenacious wrinkles. Different rejuvenating techniques that do not require surgery are available and should be prescribed by a doctor.

  • Peeling: Chemical exfoliation of the superficial layer of the skin to improve its aspect and reduce some defects.
  • Dermabrasion: Mild mechanical “sanding” of the superficial layers of the skin.
  • Photorejuvenation using pulsed light (stimulates the production of collagen using light) or laser (abrasion of the superficial layers of the skin).
  • Injections: The injection of filler products are today fully developed, starting by injections of hyaluronic acid, major product of aesthetic medicine clinics.

Hyaluronic acid

It is naturally present in our body, especially in the dermis which contains 50% of total hyaluronic acid. It has been used since several years by doctors in form of injections within wrinkles. Once injected, it acts as a sponge and becomes saturated with water bringing volume, flexibility and plumpness to the skin. Therefore, hyaluronic acid outlines the face, fills unattractive hollows and reduces, from the interior, the deepest wrinkles.

In the same way, it reduces the shadows under the eyes.

Botox®

Botulinum toxin temporarily freezes the muscles; it is used as intramuscular injections to limit the expression of wrinkles.

 Aesthetic surgery

When aesthetic medicine and care are not enough to mask the wrinkles and the saggy face, aesthetic surgery may be indicated, under local or general anaesthesia, after consult with a qualified plastic surgeon.

  • Lifting: Small incisions are performed to lift-up and tighten the skin.
  • Gold lift: Gold threads are inserted under the skin to tighten it.
  • Lipofilling: Injection of fat cultured from thighs, hips or belly of the patient within the wrinkles.

The benefits of medicine and aesthetic surgery must be daily maintained with suitable cosmetic care.


Faq

1 . When should someone start using anti-aging creams?

Starting from 25-30 years old, which means when the skin starts to be marked and the first lines emerge. However, it is never too late to start!
This does not however prevent, since the younger age, to avoid damaging factors, starting from sun exposure.

2 . Do early wrinkles have a genetic origin?

There are in fact two types of wrinkles. Expression wrinkles which are genetically determined and appear quite early. They are sometimes emphasized by an increased mobility of the face (frowns under the sun, vexations, particular funny faces...).
And there are age-related wrinkles, also determined by genetics but they appear later, around thirty; except, of course, in case of sun overexposure, tobacco or too short nights.

3 . Is injection of filling care products painful?

Today, there are very thin injection needles that are covered with anaesthetic products. The injection itself is painless.
