Neuropathic pain in patients with chronic leg ulcers.

BACKGROUND: Leg ulcers are a frequent and often painful disorder. This pain is not always correctly evaluated and relieved. OBJECTIVES: The aim of this prospective study is to assess the contribution of neuropathic pain in leg ulcers. METHODS: A visual analog scale and the DN4 questionnaire were fulfilled by 81 patients with leg ulcers. RESULTS: Of the patients with leg ulcers, 58% (n = 47) had a positive DN4 score. No predictive factor leading to neuropathic pain was found. The aetiology of the ulcers did not influence the DN4 score. CONCLUSIONS: This high prevalence of neuropathic pain in leg ulcers might be explained by an impairment of peripheral nerves due to ischaemia. This study also highlights the difficulty to relieve pain in chronic wounds; 16 patients had an analogous visual scale above 7. These results should encourage practitioners to regularly screen for neuropathic pain and to initiate appropriate treatment if necessary.

[Acute pericarditis associated with Plasmodium ovale malaria]. / Péricardite aiguë associée a un accès palustre de reviviscence a Plasmodium ovale.

The purpose of this report is to describe a rare case of benign acute pericarditis associated with recurrent Plasmodium ovale malaria. It was observed in a 33-year-old soldier who was stationed in Djibouti after serving several previous stints in West Africa. A favorable clinical outcome was achieved using chloroquin (30 mg/kg on 6 days) in association with NSAID followed by salicylates for one month. Re-examination at one year showed no recurrence. This case shows that Plasmodium ovale malaria must be considered as a potential etiology for acute benign pericarditis in patients with a history of travel to endemic countries.

Cutaneous events during treatment of chronic inflammatory joint disorders with anti-tumour necrosis factor alpha: a cross-sectional study.

BACKGROUND: Anti-tumour necrosis factors (anti-TNF) are more and more used, but the rate of skin adverse events is not known. OBJECTIVE: The aim was to assess the number of skin infections and other dermatoses in patients treated with anti-TNFalpha. PATIENTS AND METHODS: One hundred eighty-seven patients suffering from rheumatoid arthritis or ankylosing spondylitis underwent a dermatological exam. Patients with anti-TNF were compared with those without this treatment in a prospective transversal study. RESULTS: Among them, 59 patients were treated with anti-TNFalpha and steroids were prescribed in 100 cases. There was no difference in the prevalence of skin infections or eczema or tumours. Skin drug reactions were observed in six patients. Infections by dermatophytes appear very frequent, approaching 70% in both groups. CONCLUSIONS: This study shows that skin infections (or other skin diseases) are not more frequent in these patients. No differences were observed in infections (bacterial fungal, parasital or viral), tumours, psoriasis or the manifestations of atopic dermatitis. Nonetheless, a long-term survey might be interesting, especially about skin tumours.

[Skin and mucosal manifestations of chikungunya virus infection in adults in Reunion Island]. / Manifestations cutanéo-muqueuses de l'infection par le virus chikungunya chez l'adulte à la Réunion.

Numerous skin and mucosal manifestations were observed during the 2005-2006 chikungunya epidemic in Reunion Island. A prospective study was carried out in a consecutive series of 212 patients treated for chikungunya at the emergency unit of the Saint-Pierre Hospital in Reunion Island from March 8 to April 27, 2006. Diagnosis of chikungunya was suspected in patients with fever and joint pain and confirmed by RT-PCR and/or serology (IgM). Skin involvement was observed in 50% of patients. It consisted of exanthema with patches of healthy skin mainly on the trunk and limbs that sometimes displayed diffuse, congestive and even edematous features. Itching was reported in some cases (19.3%) and was sometimes isolated. Peeling of the skin was observed in a few cases but remained uncommon in adults. Outcome was rapidly favorable in most cases sometimes with scaling or persistence of dyschromic patches. These findings suggest that chikungunya should be suspected in subjects presenting a febrile rash while in an endemic areas or after returning from a tropical zone.

[Venous ulcer on the hand due to a treatment-related arteriovenous fistula]. / Ulcère veineux de la main secondaire à une fistule artérioveineuse thérapeutique.

BACKGROUND: An arteriovenous fistula of the arm for hemodialysis needs to last long and provide easy access for puncture. CASE-REPORT: A 50 year-old woman, with type 2 diabetes complicated by chronic renal failure, presented with an ulcer on the dorsum of the right hand that had developed over the past year. Humeral artery to basilica vein, side-to-side, arteriovenous fistula in the right arm was created in 1996. In 1999, she received a renal transplant. In 2002, she developed a deep ulcer on the dorsum of the right hand that progressed over one year, without improvement good local treatment. Doppler echography and a fistulography revealed proximal stenosis of the basilica vein, and a less restricted distal stenosis before the shunt. A venous ulcer on the dorsum of the hand due excessive venous pressure in the draining area. DISCUSSION: The complications of arteriovenous fistulas can be severe. Arterial stenosis is frequent and is the consequence of intimal hypertrophy. Chronic ischemia symptoms can be observed, but the hemodynamic loss is usually asymptomatic. When clinical signs are noisy emergency surgery is required. Venous stenosis is responsible for ischemia through venous overload, leading to edema of the arm, and rarely to venous-ulcer type trophic disorders as seen in this patient. Screening for stenosis on the vascular vein network must be systematic before creating an arteriovenous fistula.

Shaving: a simple and effective treatment for moderate congenital hypertrichosis.

Congenital hypertrichosis is a rare disorder. It is sometimes associated with facial dysmorphism, and dental and gingival abnormalities. This condition constitutes an esthetic problem and regular shaving with a simple razor can be a simple method of treatment.

Numerous and large Bier's spot associated with pregnancy.

We report a patient with anemic macules over cyanotic skin which started in the 8th month of a normal pregnancy. We thought that these lesions were close to Bier's spot description although it has never been described during pregnancy. The relationship with pregnancy is likely because skin lesions regress in post-partum. It probably represents an exaggerated physiological response of small vessels to venous hypertension observed during pregnancy in predisposed women.

Hyperpigmentation of the distal phalanx in healthy Caucasian neonates.

Transient alterations in pigmentation are frequently observed in black neonates, but to our knowledge, have not previously been reported in Caucasian infants. In 54 Caucasian newborns, we found at least mild periungual hyperpigmentation similar to the variation in coloration in the periungual region of many black newborns. This pigmentation should be added to the transient benign dermatoses of Caucasian infants.

[Warts and molluscum contagiosum: practical point of view]. / Verrues et molluscums contagiosums: mise au point pratique.

Warts and molluscums contagiosums are two benign viral skin diseases that commonly affect children. Contamination occurs by autoinoculation or during skin to skin contact. Molluscums contagiosums are more frequent in immunodeficient and atopic children. Swimming-pool practice and contact sports favour warts transmission. The choice of treatment depends upon the age of the child and the number and location of the lesions. Natural resolution can be awaited when lesions are limited. In first intent, curettage of the lesions under local anesthesia for molluscums contagiosums, salicylic acid preparation or cryotherapy according to location for warts, are the treatment of choice. In neither affection school ousting is necessary.

[Neonatal toxic erythema: 3 atypical cases]. / Erythème toxique néonatal: trois observations atypiques.

UNLABELLED: Diagnosis of pustular dermatosis occurring during the first days of life is based on clinical findings. Erythema toxicum neonatorum (ETN) is the more frequent benign self limiting eruption in the newborn. CASE REPORTS: Three cases of ETN with localized pustules to the genitals and perineal area are described. COMMENT: When encountering a newborn with a localized pustulosis rash, it is important to separate benign condition as ETN from those that require prompt diagnosis and therapy. Atypical ETN and pustular dermatosis due to bacterial or viral infections or inflammatory diseases (e.g., eosinophilic pustulosis) can be differentiated by cytological and bacterial samples.

[Survival after cutaneous metastasis: a study of 200 cases]. / Survie après métastases cutanées: étude de 200 cas.

BACKGROUND: Cutaneous metastatic disease is uncommon and the outcome after cutaneous metastasis has rarely been thoroughly studied. The objective of this work was to study the survival after diagnosis of cutaneous metastasis in a large series of patients and to evaluate survival according to the type of cancer. PATIENTS AND METHODS: This retrospective study was conducted out in the Laboratoire d'Histo-pathologie Cutanée of Strasbourg. Between 1950 to 1996, 228 patients with cutaneous metastasis were diagnosed on the basis of typical histopathology, confirmed by two dermatopathologists. We excluded lymphoma or leukaemia with secondary skin involvement. Medical and demographic data were collected from hospital data, and the "Registre du Cancer du Bas-Rhin". The type of neoplasm, the time of diagnosis of primary cancer and the time of death (or survival at 12/31/1996) was established in 200 patients, 99 men and 101 women with a mean age 62.4 +/- 13 years. We found 64 cases of breast carcinoma, 36 cases of lung carcinoma, 31 cases of melanoma and 69 cases of other cancers. Long term actuarial survival after cutaneous metastasis was calculated using by the Kaplan-Meier method. RESULTS: The median survival after cutaneous metastasis was 6.5 months (mean 22.8 +/- 43.8 months). The mortality rate was 13 p. 100 at 1 month, 48 p. 100 at 6 months and 64.5 p. 100 at 12 months. Median survival was calculated according to the primary neoplasm: breast carcinoma: 13.8 months, melanoma: 13.5 months, lung carcinoma: 2.9 months (36 cases). The outcome of patients with cutaneous metastasis of lung carcinoma was worse than those with melanoma (p < 10(-4)) and breast cancer (p < 10(-4)). Survival after cutaneous metastasis of other cancers could not be compared because of the small size of the subgroups: median survival after cutaneous metastasis of non cutaneous squamous cell carcinoma of the head and neck: 8.8 months (5 cases), cutaneous squamous cell carcinoma: 6.5 months (12 cases), carcinoma of oesophagus: 4.7 months (2 cases), colo-rectal cancer: 4.4 months (9 cases), pancreatic cancer: 3.3 months (2 cases), stomach cancer: 1.2 months (7 cases) and liver and gall bladder carcinoma: < 1 month (3 cases). Survival beyond 10 years was observed in 9 patients: 3 melanoma, 2 breast cancers, 2 prostatic carcinomas, 1 larynx carcinoma and 1 cutaneous squamous cell carcinoma. CONCLUSION: This is the first study in which the survival after the occurrence of skin metastasis was systematically analysed in a large series of patients. It shows that half of patients with cutaneous metastasis die within the first 6 months after the diagnosis. Those cases due to lung carcinoma have the poorest prognosis.

[Lymph node and cutaneous syndrome associated with bone plasmacytoma]. / Syndrome adéno-cutané associé au plasmocytome osseux.

INTRODUCTION: We report two patients in whom a slowly growing erythematous thoracic lesion led to the diagnosis of an underlying plasmocytoma. After the treatment of the latter, the cutaneous lesions disappeared, strongly suggesting a link between the two manifestations. CASE REPORTS: The two male patients, aged respectively 66 and 73 years old, had erythematous thoracic plaques. In both cases, extensive laboratory work-up and a histological examination of a cutaneous biopsy did not allow a precise diagnosis. The two patients had a solitary bony plasmocytoma located beneath the cutaneous plaques. The plasmocytomas were discovered respectively 2 and 4 years after the first cutaneous manifestations and were associated to histological non-specific lymph node hyperplasia. Treatment of the plasmocytoma led to the disappearance of skin lesions in both patients. DISCUSSION: In both cases, an erythematous scleroderma-like plaque associated to palpable peripheral and mediastinal lymph nodes, was located over a solitary bony plasmocytoma. Treatment of the plasmocytoma led to the disappearance of the cutaneous lesions, strongly suggesting a link between the two manifestations. Such an association has not been previously reported. We think this is a new entity, characterised by a scleroderma-like cutaneous plaque overlying a solitary bony plasmocytoma and associated to superficial and deep lymph node hyperplasia. We suggest to call it "plasmocytoma associated cutaneous lymph node syndrome". Its relationship to the POEMS syndrome and scleromyxedema are discussed. The pathophysiology remains completely unknown; the syndrome regresses after the treatment of the plasmocytoma.

[Oculomotor nerve paralysis with complete ptosis in herpes zoster ophthalmicus: 2 cases]. / Paralysies oculomotrices avec ptosis complet au cours du zona ophtalmique: deux observations.

INTRODUCTION: Only few studies focus on ocular motor paralyses in herpes zoster ophtalmicus. We report 2 cases of complete ptosis resulting from paralysis of the superior lid levator, appearing at day 6 and 7 of an ophtalmic herpes zoster under treatment with acyclovir. CASE REPORTS: Case 1: A 68 year old woman presented an history of ophtalmic herpes zoster with kerato-conjunctivitis and uveitis treated with acyclovir. At the third day of the treatment and 7th day of the ophtalmic zoster, an incomplete paralysis of the oculomotor nerve appeared resulting in a complete ptosis. The treatment was carried on until the 21st day without improvement. Four months later, all symptoms had completely cleared. CASE 2: A 66 year old woman was treated with acyclovir for an ophtalmic herpes zoster without ocular involvement. At the 4th day of the treatment and 6th day of the onset of the ophtalmic zoster, a paralytic ptosis and a acute epithelial keratitis appeared. Acyclovir treatment was continued for 10 days. The ptosis resolved gradually during 2 months. DISCUSSION: The manifestation of a complete ptosis with paralysis of the oculomotor nerve or of one of its branch is rarely seen in ophtalmic herpes zoster. However minor symptoms are often detected when patients were carefully examined with regard to external ocular movements. The physiopathological mechanism are discussed about. The possible action of an early antiviral treatment on the prevention of these complications is not known. In our two cases, a paralytic ptosis broke out suddenly, even under treatment with acyclovir for respectively 3 and 4 days. For future prospective studies about antiviral drugs for ophtalmic herpes zoster, a systematic evaluation of these neurological symptoms would be interesting.

[Universal dyschromatosis: a familial case]. / Dyschromatose universelle: une observation familiale.

INTRODUCTION: Universal dyschromatosis is a generalized leucomelanodermia recognised in Japan in 1933. We report a family with universal dyschromatosis, demonstrating the mode of transmission. The ultrastructural aspects are compatible with a functional melanogenesis anomaly. CASE REPORT: A 9-year-old girl was hospitalized for recently diagnosed insulin-dependent diabetes mellitus. She was born to non-consanguinous parents and her past medical history was uneventful. Her father was of mixed ethnic origin. The physical examination revealed generalized leukomelanoderma identified since the first year of life. Zones of small achromatic maculae alternated with zones of pigmented maculae of variable size and color. Lesions were diffuse but predominated on the trunk and did not involve the face, the hands or the feet. Neither the child nor her father who also has leukomelanoderma were photosensitive. A skin biopsy from the gluteal region revealed alternating zones of hyper- and hypopigmentation. The ultrastructural analysis showed that the number of melanocytes was not significantly different in the different pigmented zones and the pigment transfer to adjacent keratinocytes was intact. There were three other girls in the kinhood and two, as well as a few other individuals in the family, had a localized form of the disease. DISCUSSION: Universal dyschromatosis is a rare genodermatosis. The familial cases reported here illustrate the variable clinical presentations of this pigmentary abnormality. The pedigree in this family demonstrated incomplete penetrance of hereditary leukomelanoderma with autosomal dominant inheritance. The localized forms reported to date under different names would actually appear to correspond to incomplete expression of the dermatosis. The skin manifestations in universal dyschromatosis would appear to be similar to those in a few other skin diseases, mainly xeroderma pigmentosum, especially the localized forms; for generalized forms however, there is little room for confusion as photosensitivity is absent and lesions predominate in unexposed zones. The ultrastructure investigations showed different levels of melanocyte activity without abnormal pigment production or transfer. This abnormality has variable expression, explaining the multitude of clinical presentations.

[Pili multigemini: a pilar dysplasia with linear disposition]. / Pili multigemini: une dysplasie pilaire à disposition linéaire.

BACKGROUND: Pili multigemini is an uncommon pilar dysplasia with linear disposition which could be explained by the pattern of Blaschko's lines. CASE REPORT: A 37-year-old man with no medical history developed pili multigemini over a heavily bearded chin. DISCUSSION: Mili multigemini is an uncommon developmental defect of hair follicles resulting from hairs with multiple matrices and papillae emerging through a single pilosebaceous canal. This defect has a linear distribution on the chin we found to follow Blaschko's lines. Pili multigemini has been observed in association with a few rare malformations. Treatment is difficult.

[Kikuchi's disease associated with cutaneous manifestations evoking Well's syndrome]. / Maladie de Kikuchi associée à des manifestations cutanées évocatrices d'un syndrome de Wells.

BACKGROUND: Wells' syndrome is a dermatological disease with polymorphous lesions characterized histologically by an eosinophilic infiltrate of the dermis with edema and flame figures. Kikuchi's disease is a benign cause of lymphadenitis corresponding histologically to a necrotizing histiocyting adenitis without neutrophils. We describe the association of a Kikuchi's disease and cutaneous lesions similar to Wells'syndrome. OBSERVATION: A 62-year-old man presented over 3 years several simultaneous episodes of left axillary lymphadenitis and of cutaneous lesions compatible with a diagnosis of Wells'syndrome. No precipitating event or disease described with the Wells'syndrome was established. Concerning the axillary nodes, a cancer, a lymphoproliferative syndrome, a systemic lupus and several infectious diseases were excluded. Standard histology and immunochemistry of a lymph node showed signs of Kikuchi's disease. Bilateral anterior uveitis was incidentally detected. The three conditions improved with oral corticosteroids (1 mg/kg/d). DISCUSSION: The patient had Kikuchi's disease and a recurrent dermatosis for which the clinical and histological aspects, the evolution and the absence of arguments for another cause, suggest a Wells'syndrome. Cutaneous manifestations occur in 16 to 40 p. 100 of cases of Kikuchi's disease and often have characteristic histologic features not corresponding to Wells'syndrome. The association of the 2 diseases may be then incidental, despite 4 simultaneous episodes. Two viral agents, VIH and VZV have been associated with the two diseases but do not seem to be the cause in our patient. Concerning the anterior uveitis, a single case of uveitis has been described for each condition.

[AIDS-related eosinophilic folliculitis. Efficacy of high dose topical corticotherapy]. / Folliculites à éosinophiles associées au SIDA. Efficacité d'une corticothérapie locale forte.

INTRODUCTION: A chronic pruriginous eruption of eosinophil-rich follicular papules and pustules is observed in AIDS patients. The pathogenesis of this disease, termed eosinophil folliculitis, is poorly understood and treatment is debated. CASE REPORT: A 30-year-old woman with AIDS developed highly pruriginous lesions of 5 month duration localized on the face, the trunk and upper limbs. There were papulo-pustules and excoriated papules. The elementary lesion was a follicular pustula. The eosinophil count was normal. The pathology examination revealed a rich eosinophil infiltration around the hair follicles and sebaceous glands as well as follicular spongiosis. Search for demodex, pityrosporons and a large number of infectious agents was negative. Oral minocyclin was uneffective. Local high-dose corticosteroids produced a remarkable effect and led to complete remission in 9 months. DISCUSSION: Most cases of eosinophil folliculitis associated with AIDS have been reported in men, but rarely in Europe. The remarkable efficacy of the local corticosteroid in this case was exceptional. This condition could result from inappropriate inflammatory reaction in AIDS induced by various factors including demodex and pityrosporon. Several therapeutic approaches have been proposed to eradicate the triggering factors and others to modify the immune response. The exceptional response to the short local treatment with corticosteroids would suggest that this approach could be proposed as first intention treatment in eosinophil folliculitis associated with AIDS.
