[Mycetoma: report of 3 cases in Falcón State, Venezuela].
This is a report of three cases of mycetome studied in our laboratory during the last four years. We also informed about the evolution of the first case produced by Pyrenochaeta romeroi nova species reported by Borelli in 1959. All the patients were farmer men, 18, 42 and 54 years old, from the semiarid and subhumid zones of Falcon State, located on the northwest region of Venezuela. Clinically, all patients presented the mycetome syndrome (subcutaneous edema, sinus tract and "granules"), with a evolution of six months to three years. The lesions were localized in the inferior limbs in two of the patients and in the thorax in one of them. The clinical diagnose was confirmed by microbiological and mycological studies, isolating Nocardia brasiliensis in two cases and Madurella grisea in one. Two patients treated with Sulfas showed remission of the disease in a two years follow up. Including this report, 15 cases of mycetome have been reported in the Falcon State (Venezuela) in a period of thirty five years, representing only 9, 14% of the national casuistic. Actinomadura madurae and N. brasiliensis have been the most frequently isolated agents in this region. In order to determine the real endemicity of the mycetome in Venezuela, multidisciplinary clinical, inmunological, microbiological and epidemiological studies are recommended. According to the reported casuistic (15 cases), the mycetome should be a low frequency disease in Falcon State, Venezuela. We confirm that early diagnosis favors an efficient therapy.

[Reflections on the treatment of acropathia ulcerans et mutilans; interest of a removable appliance (author's transl)].
The authors report their experience in the treatment of acquired ulcerating and mutilating trophic lesions of the lower limbs. Ligature of the dorsalis pedis artery and of its collaterals did not give good results, according to the pathogenic concept of the authors, in which lesions of the nervous system predominate over vascular alterations. More important lesions (such as osteo-arthritis of the first and fifth metatarsals) require immobilization of the axis of the wounded toe, control of any superinfection and use of a plastic removable limb appliance.

Airborne contact dermatitis from unexpected exposure to rosin (colophony). Rosin sources revealed with chemical analyses.
We report 3 cases of contact dermatitis in rosin-sensitive individuals caused by exposure to airborne rosin components from different sources. Case no. 1 was a female office worker with a facial dermatitis caused by rosin components which emanated from the linoleum floor covering in her office. Floor material containing wood flour and rosin was released into the air, causing a facial dermatitis in the rosin-sensitive subject. Case no. 2 involved a woman who worked in a factory producing dairy product cartons and had a dermatitis on her lower legs, lower arms and upper chest. Her dermatitis was caused by dust from the paper cartons and contact allergy to rosin components probably aggravated her dermatitis. Case no. 3 was a female office worker with a relapsing dermatitis on her eyelids. Her dermatitis was caused by a rosin-containing floor polish, which was seen as a powder on the office floor. Extracts of suspected material and products were patch tested and analysed for the presence of rosin components with HPLC and GC techniques. A discussion and recommendations on chemical analyses of rosin components follow. We conclude that a thorough investigation, including chemical analyses, can rule out non-specific diagnoses and offer a solution to the patient's skin problems.

[Erysipelas in the young population of a military hospital].
INTRODUCTION: Erysipelas usually affects either elderly patients or patients with predisposing factors. We studied erysipelas in a young healthy military population. SUBJECTS AND METHODS: A retrospective study of patients, less than 30 years old, admitted to the Hôpital d'Instruction des Armées Robert Picqué between 1991 and 1997 was performed. RESULTS: Eighty-one patients were studied, 80 were men, mean age was 21.4 years. Localization of erysipelas was: face: 2; leg: 74. Facilitating factors were: portal of entry in 100 p. 100; venous insufficiency in 1 case; alcohol abuse in 1 case. Anti-inflammatory agents had been given at the beginning of treatment in 32.1 p. 100 cases. 7.1 p. 100 patients had a recurrence.. Complications were: abscess in 8 cases and bursitis in 1 case. No facilitating factor was detected. The course was not related with bacterial findings. No thrombo-embolic complication was observed. DISCUSSION: In a young healthy population, erysipelas is not a rare infection. Face is an exceptional localization of erysipelas in relation to older population. The main risk factor for developing this infection is local factor found in 100 p. 100 cases but general factors as repeated hikes, care access, long standing could also be incriminated. Use of anti-inflammatory agents is frequent but role of anti-inflammatory agents in developing complications is not clear. Complications are rare and benign except for frequence of recurrences while the good health.

Response of leprosy patients with single lesions to MDT.
This study reports the clinical profile and therapeutic response of seventy-two mono-lesions leprosy cases. These 72 cases were among 578 paucibacillary (PB) cases classified according to WHO (1982) and were followed-up on multidrug therapy (MDT). Of these 72 mono-lesion cases, 46 (64%) were tuberculoid (TT) cases, 24 (33%) were Indeterminate (Ind) cases and 2 (3%) were of borderline tuberculoid (BT) types. While 37.5% of these cases presented as macular patches, the remaining 62.5% had raised erythematous lesions. In majority of cases (94%), the lesions were present on the exposed parts like legs and feet, arms and hands, face, whereas only 6% presented on covered areas of trunk and buttocks. These cases were treated with dapsone 100 mg daily for 12 months and rifampicin 600 mg once a month for 6 months. After 6 months of MDT, lesions in 81% of the patients regressed clinically and by one year of therapy 96% of cases had regressed. Treatment was stopped in all cases by one year of therapy. There were no relapse or late reaction in the 5 years of post treatment follow-up. The response of mono-lesion PB cases was better than the multi-lesions PB cases at 6 months and during the post treatment follow-up period.

Clinico-bacteriological study of pyodermas in children.
One hundred cases of pyodermas in children were investigated clinically and bacteriologically. Nasal and throat swabs from all cases were subjected to bacteriological examination. Most of the children (42%) were in the 1-4 year age group. The majority (58%) belonged to lower socio-economic groups with poor standards of hygiene. A history of over-crowding was obtained from 87% of cases, 82% were undernourished. Most of the children (68%) reported during the hot and humid months of June, July, August, and September. Primary pyodermas were observed in 72% of the children, and secondary pyodermas in 28%. Impetigo was the commonest primary pyoderma (48.61%); among secondary pyodermas, infected scabies was noted predominantly (42.86%). The face and legs were more commonly involved. Bacteriological cultures from pyoderma lesions revealed a single microorganism in the majority of the patients (84%). Staphylococcus aureus was isolated in pure culture from 48% and pure beta-hemolytic streptococci from 36%. A combination of both was obtained from 16%. No other organism was isolated from any case. A similar pattern was also observed in cultures from the nose and throat. Only 46 out of the 64 strains (84.3%) of Staphylococcus aureus isolated from pyoderma were typable. The majority (39.1%) showed a mixed pattern of phages; the second commonest was the non-allocated phage type (30.4%). Nasal flora had more of the non-allocated phage type (50%); two out of the three strains (66.6%) isolated from the throat showed a mixed pattern. All the strains of beta hemolytic streptococci, isolated either from lesions of pyoderma, nose, or throat belonged to group A. Staphylococcus aureus and showed a high sensitivity to netilmycin (100%), ofloxacin (98.4%), amoxycillin/clavulanic acid (96.9%), ciprofloxacin (89.1%) and gentamycin (84.4%) but a high resistance to penicillin (85.9%). A greater correlation was noted between nasal flora and organisms causing pyodermas. A change in the pattern of organisms causing pyodermas in children and their antibiotic sensitivities in this part of the globe has been observed in this study. The role of endogenous nasal and throat flora in the causation of pyodermas has also been highlighted.

Nd:YAG 1064 nm laser in the treatment of facial and leg telangiectasias.
BACKGROUND: Facial and leg telangiectasias are a frequent cosmetic concern for both females and males with various skin types and ages. To date the different treatments for these problems, in particular leg telangiectasias, have frequently failed or led to negative side-effects. OBJECTIVE: This study examines the clinical effects and safety of applications with a 1064-nm Nd:YAG laser system (SmartEpil II, DEKA M.e.l.a., Florence, Italy) to treat vessels on the face and legs. MATERIALS AND METHODS: Twenty-five subjects with facial telangiectasias underwent one treatment at 100 J/cm2, 10 ms and 2 Hz repetition rate. Thirty-two subjects with leg telangiectasias, measuring 0.1-3 mm in diameter, were treated at 125-200 J/cm2, 10-30 ms and 2 Hz repetition rate. Subjects in this group underwent one to five treatment sessions at 8 week intervals. RESULTS: All subjects showed visible improvement, with 95-100% clearing of the face telangiectasias after only one treatment, and 50-100% clearing of the lower extremity vessels after three to five treatments. Transitory hypopigmentation was seen in two cases subjected to leg vessel treatment. CONCLUSIONS: Treatment of facial and leg telangectasias using a true long pulse 1064 nm Nd:YAG laser is an effective and safe method. The relative lack of discomfort combined with a high degree of individual satisfaction should play a part in the fairly high level of acceptance of this new form of therapy for the treatment of leg and face telangiectasias.

[Allergic phenomena in the treatment of leg ulcer].
First mentioning the immunological processes of contact dermatoses, the authors study the six contact allergies encountered most frequently by them during the course of 133 cases of leg ulcers which they treated. They consider in detail the allergenic action of the following six substances: lanolin, neomycin, balsam of Peru, paraben, phenylenediamine and benzocaine. They pioneer therapies intended to prevent the risk of sensitization.

[Sclerosing of varicose veins in general practice].
The great number of patients suffering from varicosis and its complications urgently requires an active therapy. This treatment simultaneously represents a prophylaxis against the development of thrombophlebitis, thrombosis, leg ulcers and hypostatic congestion dermatoses. The varicosclerosation is not bound to instrumental preliminary examinations and therefore feasable without great efforts in the outpatient department. After testing the patency of the deep veins and taking into consideration the indications and contraindications the varicosclerosation achieves good results and is nearly free from side-effects. The percentage of relapses is caused by the constitutional weakness of the connective tissue and must be taken into account from the very beginning. General practitioners and specialists of internal medicine should make use of this method, since dermatologists and surgeons alone are not able to cover the quantitative demand.

[Erosive pustular dermatosis of the leg: role of zinc deficiency?].
BACKGROUND: Erosive pustular dermatosis of the legs is a rare and recently described condition seen in elderly subjects. It is characterised by symmetric erosions of the legs resulting from a confluence of sterile pustules, usually following minor trauma. Treatment with dermal corticosteroids is rapidly effective but is not codified and relapse is common. CASE-REPORTS: Three patients aged respectively 74, 84 and 92 years presented ulcers of the legs and ankles associated with peripheral pustules following minor injury. These pustules were sterile and exhibited a spongiform appearance on histological examination. None of these patients had a prior history of psoriasis. However, all presented zinc deficiency. Treatment with dermal corticosteroids combined with oral zinc gluconate resulted in complete resolution in two of the patients after several days of therapy and proved effective during relapse in the third patient. DISCUSSION: Erosive pustular dermatosis of the legs is a benign dermatosis that is probably under-reported that should be included in the category of inflammatory neutrophilic dermatoses. The cases we present suggest a triggering or enhancing role of zinc deficiency.

Complications of ascending phlebography of the leg.
Forty patients were studied prospectively for complications of ascending phlebography. The commonest immediate complication was pain at the site of injection and the commonest delayed complication pain in the foot or calf. Out of 30 patients with pain in the foot and calf, 15 had venous thrombosis. Review of 200 case notes disclosed only one recorded complication--namely, necrosis of the dorsal skin of the foot. Complications of the procedure reported by referring clinicians over 10 years comprised four cases of necrosis of the dorsum of the foot and two of gangrene of the foot, in one of which the gangrene spread to the leg. Major complications of ascending phlebography are rare, though when they occur may cause serious morbidity. If a scrupulous technique is used contrast phlebography remains the most accurate method of diagnosing venous disease of the leg.

Phaeohyphomycotic ulcer caused by Phialophora verrucosa: successful treatment with itraconazole.
We report the first well documented case of subcutaneous phaeohyphomycotic infection caused by Phialophora verrucosa in India. Examination of the biopsied tissue from an ulcerating lesion on the shin of the left leg of a 45-year-old woman from Bombay, India, showed numerous dematiaceous, septate, branching hyphal elements and thick-walled cells characteristic of phaeohyphomycosis. Cultures of the scrapings from the lesion and of the biopsied tissue yielded a pigmented fungus that was identified as P. verrucosa. Initial treatment with fluconazole followed by oral itraconazole for 30 days and local application of a copper sulphate solution resulted in complete resolution of the lesion. Treatment with itraconazole was continued for an additional 3 months after complete healing. No new lesions developed and the patient did not show jaundice, hepatosplenomegaly or any other signs of toxicity.

An intense light source. The photoderm VL-flashlamp as a new treatment possibility for vascular skin lesions.
BACKGROUND: Up to now, vascular diseases were treated with various lasers, such as argon, pulsed dye, and copper vapor lasers, which can lead to side effects like hypopigmentations, hyperpigmentations, and scarring. We treated patients with vascular lesions with an incoherent intense light source, the PhotoDerm VL-flashlamp. OBJECTIVE: The aim of the study was to test the effectiveness and safety of the PhotoDerm VL for vascular skin lesions. METHODS: One hundred and twenty patients with facial or leg telangiectasias, spider nevi, erythrosis interfollicularis, and senile angiomas were treated with the PhotoDerm VL. RESULTS: In 73.6% of patients there was an immediate clearing, and in 84.3% a clearing after 1 month was found of leg telangiectasias up to 1 mm in diameter. Facial telangiectasias and erythrosis interfollicularis colli showed clearance up to 90%. Spider nevi and senile angiomas often only needed to be treated once. CONCLUSION: From our experience we conclude that the PhotoDerm VL is an excellent device to treat vascular lesions as there were hardly any side effects seen, however, the user needs a sufficient experience to get good results.

Purpuric generalized lichen nitidus: an unusual eruption simulating pigmented purpuric dermatosis.
BACKGROUND: Generalized haemorrhagic lichen nitidus is rare. To our knowledge, this form of presentation has only been reported once. OBJECTIVE: To describe a new case of generalized haemorrhagic lichen nitidus simulating a pigmented purpuric dermatosis. METHODS AND RESULTS: We document a 24-year-old man who presented with an 8-month history of a progressive non-pruritic, red-brown papular eruption on the dorsa of the feet, ankles and distal third of the legs. A diagnosis of Schamberg's progressive pigmentary dermatosis was made, and no treatment was prescribed. Two months later, the lesions had extended to the abdomen, groins, forearms, elbows and wrists. Biopsy of the skin of the right foot revealed lesions typical of lichen nitidus with subepidermal extravasation of red cells and capillary wall hyalinization. Macrophages and T lymphocytes were abundant in the infiltrate. CONCLUSION: Purpuric generalized lichen nitidus should be included in the differential diagnosis of pigmented purpuric dermatoses.
