[Changes in the incidence and mortality rates of malignant melanoma in the Seine-Maritime region over a 20-year period]. / Évolution de l'incidence et de la mortalité du mélanome en Seine-Maritime sur une période de 20ans.

BACKGROUND: The aim of this study was to assess changes in the incidence and mortality rates of malignant melanoma (MM) over a 20-year period in a region without a cancer registry. METHODS: All cases of MM studied were collected retrospectively from the databases of six private and three hospital-based histopathology laboratories in the Seine-Maritime region covering three 24-month periods each 10years apart: 1988-1989, 1998-1999 and 2008-2009, The incidence and mortality rates were estimated based on data provided by French National Institute for Statistics and Economic Studies (Insee) and French National Institute of Health and Medical Research (Inserm). RESULTS: Over the 20-year period, the incidence of MM increased from 8.6 to 21.2/100,000inhabitants per year (+147%, P<0.0001) while the mortality rate rose from 1.3 to 2.8/100,000inhabitants per year (+115%, P=0.0003). The incidence of invasive MM increased by +110%, while the incidence of MM in situ increased by +456%. The incidence and overall mortality rate of invasive MM increased particularly during the first 10-year period: +62% (P<0.0001) and +77% (P=0.01) respectively, and to a much lesser extent during the last 10-year period: +30% (P=0.0007) and +22% (P=0.22) respectively. This slowdown in the incidence of invasive MM and in overall mortality rates was even more pronounced in women over the last 10years (+17 and +9%), whereas these rates continued to increase in men (+49% and +35%, respectively). In contrast, the incidence of MM in situ increased above all during this same period (+257%). CONCLUSION: This study shows that while the incidence and mortality rate of invasive MM has increased little over the last 10years in the Seine-Maritime region, the incidence of MM in situ continues to rise sharply.

[Complications after sentinel lymph node excision in patients with malignant melanoma]. / Complications liées à l'exérèse du ganglion sentinelle dans le mélanome.

INTRODUCTION: Side-effects occurring after sentinel lymph node excision in malignant melanoma patients have been poorly evaluated to date. The aim of the present study was to assess the side-effects of sentinel lymph node excision in this population. PATIENTS AND METHODS: All consecutive malignant melanoma patients undergoing sentinel lymph node excision between March 2000 and December 2002 were included in this retrospective study. Patients with a metastatic sentinel node subsequently undergoing lymph node dissection were excluded. Median follow-up of patients was 12.6 +/- 8.8 months. Complications were classified as "early" (i.e. occurring the month following surgery), or "late" (after this time). RESULTS: Forty malignant melanoma patients (17 males, 23 females) with a normal histologic examination of their sentinel lymph node were included. They belonged to a series of sixty-one melanoma patients undergoing lymph node excision. Fourteen complications were observed in ten patients. Two early complications were seen: hematoma (n=1) and deep venous thrombosis with pulmonary embolism (n=1). Twelve late complications were observed: mild lymphoedema (n=5), hypertrophic scars (n=2), painful scars (n=4), and one chronic seroma (n=1). Many complications (33%) were observed after excision in the inguinal area. DISCUSSION: The complications of sentinel lymph node excision must be considered in determining the benefit/risk ratio of this technique.

[Vulvoperineoplasty for vulvar pain in the posterior fourchette (15 cases)]. / Vulvopérinéoplastie pour douleurs vulvaires localisées à la fourchette (15 cas).

BACKGROUND: Vulvar pain is a common presenting complaint in dermatology consultations arising from numerous possible causes. Where such pain is mechanical, resulting from stretching of the vulva, particularly during sexual intercourse, the patient should be checked for anatomical features that could account for the pain, localised anatomical adhesions or sclerosis of the fourchette, and amenable to treatment by vulvoperineoplasty. PATIENTS AND METHODS: A retrospective study of all patients undergoing vulvoperineoplasty for vulvar pain in the fourchette was carried out between 1.1.1993 and 1.1.2003. RESULTS: Fifteen successive patients were included in the study. The mean rate of sexual intercourse doubled between the pre-operative period and the post-operative period, rising from 5 (0 to 30) to 9.8 (3 to 30). Mean pain intensity during intercourse on a scale of 1 to 10 fell from 7.6 (5 to 9) before surgery to 1.6 (0 to 5) after surgery. None of the patients experienced any sequelae. All patients except one (who was no longer sexually active), expressed willingness to undergo vulvoperineoplasty again if necessary. DISCUSSION: Vulvoperineoplasty is a simple procedure and proved useful for female patients presenting vulvar pain and adhesions or sclerosis of the fourchette.

[Treatment of pemphigus vulgaris by azathioprine and low doses of prednisone (Lever scheme)]. / Traitement du pemphigus vulgaire par le protocole Lever faible.

INTRODUCTION: The so-called "Lever scheme" therapeutic regimen has been proposed in the borderline forms of pemphigus to reduce the side effects of systemic corticosteroids. PATIENTS AND METHODS: A retrospective study was conducted in 8 hospital centers. The criteria for inclusion were the clinical diagnosis of pemphigus, confirmed by histological examination and direct immunofluorescence and first line therapy using the "Lever scheme" protocol, combining 40 mg of prednisone on alternate days and 100 mg/day of azathioprine. RESULTS: Twenty-two patients, seen between January 1990 and December 2000 were included in the study. Eighteen patients (82 p. 100) exhibited complete healing of their cutaneous-buccal lesions after a mean delay of 4.3 months. The lesions of 4 patients did not heal. Three of these patients died: a bed-ridden patient, a patient exhibiting a metastatic bronchial carcinoma and a hypertensive patient who died following a hemorrhagic cerebral vascular accident. Twelve patients (54 p. 100) were weaned off treatment after a mean duration of 2.9 years. Five severe adverse events were observed: one pneumonia, 2 unbalanced diabetes, one hepatitis and one pulmonary embolism. DISCUSSION: This study showed that the healing of the cutaneous-buccal lesions was obtained using the "Lever scheme" in 18 cases out of 22 (82 p. 100). The delay to healing was relatively long in view of the delayed effect of azathioprine. This limits the use of the "Lever scheme" protocol to non-extensive and/or early stage pemphigus. The severe adverse events occurred in low-weight patients in whom the dose related to weight was the highest. Hence the doses of azathioprine and prednisone should be adapted to patients' body weight.
