We studied the clinical and electroencephalographic features in 30 children who were diagnosed with childhood absence epilepsy. According to their EEG pattern we divided the 30 children into two groups: group A: 11 children with classical absences whose ictal EEG showed primary generalized spikes and waves and group B: 19 children with frontal onset of the EEG epileptic abnormalities ('frontal group'). In the frontal group, more frequently complex absences were seen. Although the majority of children responded very well to valproate monotherapy, ethosuximide has to be added in 3 children of the frontal group to achieve seizure freedom. In the frontal group, also more learning and behavioural problems were encountered. This study largely confirms a previous study of Lagae et al. [Lagae L, Pauwels J, Monte B, Verhelle J, Vervisch J. Frontal absences in children. Eur J Pediatr Neurol 2001;5:243-251]. It seems that frontal onset absences constitute a specific subtype within the childhood absence epilepsies.

Venous leg ulcers represent a significant public health problem that will increase as the population ages. Numerous herbs and their extracts are potentially conducive to wound healing, including the ability to serve as an antimicrobial, antifungal, astringent, etc. A total of 32 patients with venous leg ulcers were randomized into two groups: a group with herbal therapy treatment (PT) (17 patients) and a control group (C) (15 patients). The investigation focused on five controls of parameter changes important for ulcer healing and the control of microbiological flora. Within-treatment analysis of the PT group showed that, following herbal therapy treatment, there was a significant decrease in the scores of surface leg ulcer and venous leg ulcer after week 7 of treatment (p < 0.05). In group C following topical antibiotic treatment there was no significant decrease in the surface leg ulcer. Comparing the results of decreased venous leg ulcer surface of the) PT group with the C group showed a significant difference at p < 0.05 after week 7 of treatment. The number of different types of isolated bacterial species decreased significantly (p < 0.05) after the use of herbal preparations. The results of this pilot study demonstrate the healing and antimicrobiological effects of herbal therapy on non-infected venous leg ulcer.

Introduction: Basal cell carcinoma is the most common tumor of the eyelid. In this region, reconstruction is complex and damage to healthy tissue should be minimal. Objective: To define the relationship between margin clearance at excision and the recurrence rate of basal cell carcinoma of the eyelid. Methods: This prospective study was conducted with 111 patients submitted to surgery for basal cell carcinoma of the eyelid between 2001 and 2003 and followed up for a period of five years. The patients were evaluated according to age, tumor site, recurrence rate and margin clearance at excision. Results: No significant association was found between incomplete tumor excision and recurrence except in patients under 56 years of age, female patients and in the case of tumors of the medial canthus. Conclusion: A risk of recurrence in incompletely excised basal cell carcinomas of the eyelid was only confirmed in younger patients, females and for tumors of the medial canthus. Keywords: Basal cell carcinoma; eyelid; recurrence.Resumo: Introdução: O carcinoma basocelular é o tumor mais comum entre os tumores das pálpebras. Nesta região, a reconstrução é complexa e recomenda-se que haja perda mínima de tecido saudável. Objetivo: Para definir a relação entre margem livre de tumor na excisão e taxa de recidiva do carcinoma basocelular das pálpebras. Métodos: Este estudo prospectivo incluiu 111 pacientes operados para remoção de carcinoma basocelular das pálpebras no período de 2001 a 2003, com acompanhamento subsequente de 5 anos. Os pacientes foram avaliados de acordo com a idade, localização do tumor, taxa de recidiva, e margem livre de tumor na excisão. Resultados: Não se encontrou associação significativa entre a excisão incompleta do tumor e casos de recidiva, exceto em pacientes com idade inferior a 56 anos, pacientes do sexo feminino e em tumores do canto medial. Conclusão: Um risco maior de recidiva de carcinoma basocelular das pálpebras com excisão incompleta foi confirmado estatisticamente apenas em pacientes mais jovens, em mulheres, e nos tumores do canto interno.

The urinary excretion of total androstenedione i. e. free, glucosiduronide and sulphate, testosterone and dehydroepiandrosterone during two normal menstrual cycle is presented. Epitestosterone was determinated during one cycle only. Both cycles were ovulatory as can be seen from the pregnanediol and oestriol determinations. The androstenedione and testosterone excretion values showed a caracteristic decrease from 12th to 16th day and an increase during the luteal phases, reaching their maximal levels between the 20th and 25th (cycle A) and 20th and 24th day (cycle B) respectively. The excretion values of epitestosterone were highest on 22nd and 23rd day. Dehydroepiandrosterone values were also slightly raised during the luteal phase of the cycle.

toll-like receptor 7 agonist imiquimod has been used to treat cutaneous melanoma metastases, [5] although in small numbers of patients we have found it much less effective than diphencyprone in this setting. [3] Imiquimod is also >100 times more expensive than diphencyprone, which costs approximately $US1 per month. Lentigo maligna is another condition where excision may be cosmetically difficult and where topical immunotherapy can play a role. Currently reported cure rates for lentigo maligna using imiquimod are~50-88%. [6] Trials may now be indicated, initially with histologic confirmation of response, using diphencyprone for these lesions.

Segmental neurofibromatosis is a rare clinical finding generally with no family history and facial involvement. There are four subtypes of segmental neurofibromatosis: true segmental, localized cases with deep involvement, hereditary segmental and bilateral segmental neurofibromatosis. Here we report three patients from the same family (father, son and granddaughter) with segmental bilateral neurofibromatosis on the face. This form hasn't noticed in the literature.

Basosquamous carcinoma of the skin is a relatively rare cutaneous neoplasm that has significant metastatic potential and a metastatic rate greater than that of basal cell and squamous cell carcinoma. We describe the use of lymphatic mapping and sentinel lymph node biopsy in a 63-year-old man after identification of basosquamous carcinoma. Sentinel lymph node biopsy, which is a standard tool to detect regional lymphatic metastasis in cutaneous melanoma, has been rarely employed to detect lymphatic metastasis of basosquamous carcinoma. The approach was successful in detecting a regional lymphatic metastasis of two nodal basins with minor morbidity. Sentinel lymph node biopsy may be useful for certain high-risk lesions of basosquamous carcinoma.

AbstractOnly few studies have reported that bone fracture risk is decreased in hypercholesterolemic postmenopausal women treated with statin therapy. Because of a lack of longitudinal studies on the effect of statins on bones, the aim of our investigation was to estimate the simvastatin therapy effects on bone mineral density in hypercholesterolemic postmenopausal women. Our investigation was carried out on 53 postmenopausal women with hypercholesterolemia. The women included in the study were divided into two groups. Group 1 was comprised of women with two or more (n=32) atherosclerosis risk factors, whereas group 2 had women with less than two (n=21) of these risk factors. All the women included in the study were placed on a hypocholesterolemic diet and the women in group 1 were additionally treated with 20 mg of simvastatin daily. The parameters of lipid status, body mass index, and L2–L4 densitometry were determined at baseline and then after one year. The simvastatin-treated group showed significant improvement of lipid parameters and increased bone mineral density. Finally, changes in bone mineral density between the groups showed significant differences (p<0.05). Although our investigation was carried out on a small group, our results showed a positive effect of the simvastatin therapy on the bone mineral density of postmenopausal women.
