Disseminated Sporotrichosis: An Important Differential Diagnosis for Venous Ulcers.

The authors present the case of a 45-year-old immunosuppressed man with lower extremity ulcers. Initially treated as venous ulcers, the wounds were later correctly diagnosed as cutaneous disseminated sporotrichosis. After appropriate treatment with systemic antifungals was initiated, the patient healed within 4 months.

Efecto de un suplemento nutricional específico (Balnimax(R)) en la cicatrización de úlceras de la extremidad inferior de etiología venosa y úlceras por presión / Effect of a specific nutritional supplement (Balnimax(R)) on lower extremity ulcers of venous etiology and pressure ulcers

Objetivo: evaluar un suplemento nutricional específico, Balnimax(R) (ácido alfa-lipoico, L-arginina, L-metionina, complejo de vitamina B, vitamina E y selenio) junto con la práctica clínica diaria en la cicatrización de las úlceras por presión y úlceras de etiología venosa. Material y método: se llevó a cabo un estudio multicéntrico, prospectivo, de medidas repetidas en un solo grupo y postautorización en pacientes con úlceras por presión y úlceras de etiología venosa sin signos clínicos de infección local, que fueron tratados durante 8 semanas. Las medidas se registraron al inicio y en las semanas 2, 4, 6 y 8. Los pacientes recibieron una cápsula oral dos veces al día, con las comidas. La medida de resultado principal fue el porcentaje de reducción en el tamaño de la herida. Además, se estudió la cicatrización completa. El tamaño de la muestra se determinó para comparar los resultados frente a un valor de referencia. Se requería un total de 127 pacientes para detectar una diferencia igual o superior al 15% en la reducción del área. Se asumió como porcentaje de reducción de referencia un 57%. Además, se estimó un 10% de pérdidas en el seguimiento. Resultados: Se incluyeron y finalizaron el estudio 112 pacientes con 133 heridas (un 16,0% tuvieron dos o más lesiones), con una media de edad de 74,2 ± 12,0 (mediana: 77, extremos: 35-94). Un 69,8% eran mujeres, la mayoría pacientes ambulatorios (98,4%). En un 9% se utilizaron moduladores de las proteasas y solo en un 27,2% se aplicó un vendaje compresivo multicapa. Un total de 58 (43,6%) úlceras cicatrizaron durante el periodo del estudio. La evolución del tamaño de la herida y su porcentaje de reducción fueron estadísticamente significativos (p ≤ 0,001), disminuyendo a lo largo del tiempo. Hubo diferencias estadísticamente significativas entre los resultados del estudio y el valor de referencia (p ≤ 0,001). Conclusiones: a pesar de las posibles limitaciones metodológicas por ser un estudio en un solo grupo, el complemento estudiado parece tener un efecto sobre la cicatrización. Los resultados son mejores que los publicados previamente con otros suplementos nutricionales o frente a la cura en ambiente húmedo por sí sola

Objective: To evaluate a specific oral nutritional supplement, Balnimax(R) (alfa-lipoic acid, L-arginine, L-methionine, vitamin B complex, vitamin E and selenium) along with daily clinical practice on the healing of pressure and venous leg ulcers. Method: a multicentre, prospective, single-group, repeated measures and post-authorization study was carried out with pressure and venous leg ulcers’ patients without signs of local infection, to be treated for up to 8 weeks. Measures were recorded at baseline, 2, 4, 6 and 8 weeks. The patients received a tablet orally twice daily with meals. The primary outcome variable was the percentage of wound size reduction. We also analysed the complete healing. The sample size calculation was determined to compare the results against a reference value. 127 subjects would be required to detect a difference equal to or above 15%. It was assumed that the percentage of wound reduction was 57%. We estimated a loss rate of up to 10%. Results: 112 patients with 133 wounds were included and finished the study (16.0% had 2 or more wounds), with a mean age of 74.2±12.0 (median: 77, extremes: 35-94). 69.8% were women, most of them ambulatory patients (98.4%). In 9% proteases modulators were used and in only 27.2% was applied a multilayer compression therapy. 58 (43.6%) ulcers healed during the study period. The evolution of wound size and percentage reduction was, statistically significant (p ≤ 0.001), decreasing over time period. It was a statistical significant difference (p ≤ 0.001) between the results and the reference value. Conclusions: Despite the possible methodological flaws due to a single-group study, the supplement studied seems to be an effect over healing. The results are better than previous published with other nutritional supplements or with moist wound healing only

[Pyoderma gangrenosum, a nonintestinal manifestation of Lesniowski-Crohn's disease in a 15 years old girl]. / Zgorzelinowe zapalenie skóry jako pozajelitowa manifestacja choroby lesniowskiego-crohna u-15 letniej dziewczynki.

In the clinical course of Lesniowski-Crohn's disease in children, gastrointestinal symptoms are predominant. Extraintestinal manifestations are found rarely, contrary to adults. Pyoderma gangrenosum is hardly ever observed but frequently coexists with colon involvement. The aim of the study was a presentation of 15 years old girl with Lesniowski-Crohn's disease and predominant joint and skin symptoms in form of pyoderma gangrenosum. Skin lesions were shaped in solitary ulcerations with cyanotic undermined border localized on legs and buttocks. After steroid therapy these changes were healed with permanent blue scar. Gastrointestinal symptoms though slight were characteristic. The girl had stools with some fresh blood and perianal lesions.

A systematic approach to medical decision-making of uncommon clinical pictures: a case of ulcerative skin lesions by palm tree thorn injury and a one-year follow-up.

In clinical practice, the clinician is challenged with symptoms and/or signs at times apparently insoluble by diagnostic and/or therapeutic means. We propose that in these cases, we have to use an EBM approach in which evidence may be looked up in every available clinical report and bibliographic databases are used for searching that evidence. We report on a case of ulcerative skin lesions apparently insoluble by expert dermatologists following a conventional diagnostic and therapeutic process. We use this case report for illustrating a systematic approach to resolve diagnostic and therapeutic questions using a bibliographic database search (like MEDLINE and EMBASE). Both a systematic approach to bibliographic databases and a critically appraised topic on case reports (or case series) are needed to 'rehabilitate' low-level evidences (that is a case report or case series) to a higher level when we approach decision-making of uncommon clinical pictures. We demonstrate the possibility of using bibliographic databases to search and retrieve useful information for decision-making of uncommon clinical pictures. The method we have proposed can be applied in every area of the world, especially in rural areas. Finally, an Internet-shared database of uncommon clinical pictures with critically appraised topics could be useful in saving more time.

Oral zinc for arterial and venous leg ulcers.

BACKGROUND: Leg ulcers affect up to 1 per cent of people at some time in their life. Management includes care of the ulcer using dressings and treatment of underlying medical problems such as malnutrition, lack of minerals, vitamins, poor blood supply or infection. OBJECTIVES: To assess the effectiveness of oral zinc in healing arterial or venous leg ulcers. SEARCH STRATEGY: Searches of 19 databases, hand searching of journals and conference proceedings from 1948 onwards, and examination of bibliographies. The company manufacturing zinc sulphate tablets was asked for references to relevant trials. SELECTION CRITERIA: Randomised controlled trials comparing oral zinc sulphate with placebo or no treatment in patients with arterial or venous leg ulcers. There was no restriction on date or language. The main outcome measure used was complete healing of the ulcers. Trials were eligible for inclusion if they measured ulcer healing objectively, by time to complete healing, proportion of ulcers healed during the study, or healing rates of ulcers. DATA COLLECTION AND ANALYSIS: All data extraction and assessment of trial quality were done by both authors independently. MAIN RESULTS: There were six eligible trials. All are small and serum zinc was measured at baseline or during the trial in 4 trials. Overall there is no evidence of a beneficial effect of treatment with zinc sulphate on the number of ulcers healed at the end of the trials. There is some evidence that oral zinc might have a beneficial effect on healing of venous ulcers in people with a 'low' serum zinc level at baseline. REVIEWER'S CONCLUSIONS: Overall, oral zinc sulphate does not appear to aid healing of leg ulcers, although it might be beneficial in those with venous leg ulcers and low serum zinc. Further research is needed to ascertain the serum zinc concentration below which treatment with zinc might be beneficial, and the dose required. [This abstract was prepared centrally]

Malignant transformation in trophic ulcers in leprosy: a study of 12 cases.

Twelve cases of carcinomata arising in Trophic ulcers of Leprosy are presented. Out of these, 10 were on the plantar surface more commonly on the proximal part of foot, one on lower leg and dorsum of foot, and one in an ulcer over the lateral malleolus. Almost all presented with infected growths and regional lymphadenopathy. Three cases presented with advanced disease with fungating inguinal nodes and were fatal. Nine cases underwent below knee amputation under antibiotic cover as a definitive treatment and the lymph nodes were kept under observation. Histologically, all were low grade squamous cell carcinomas. In most cases lymph nodes regressed after removal of primary and in one case lymph nodes were positive for malignancy. This study was conducted at Dr. Bandorawalla Leprosy Hospital, Kondhawa, Pune 22 from the year 1981 to 1987.
