[en] A series of 274 cases with eyelid carcinoma, 95 per cent irradiated, was analyzed. The results show that the majority of eyelid carcinomas can primarily be irradiated with satisfactory curative and cosmetic results, but operation may be considered in larger and deeper infiltrating tumours. Recurrence after primary irradiation should be operated. (Auth.)

[en] Acne vulgaris is a condition in which several pathogenic factors are involved. Based on the clinical picture, mild, moderate, and severe forms of acne are distinguished. In particular, severe forms of acne require complex treatment with systemic drugs supplemented with topical preparations. The first part of the paper deals with the basics of acne vulgaris as well as with acne conglobata, acne inversa, acne fulminans, and acne infantum. The therapeutic options in these severe forms of acne are outlined. The second part is focused on rarer forms of acne which are also included in severe forms of the disease due to their course and clinical picture. These include, in particular, tropical acne, body-building acne, androgenizing syndrome, SAHA syndrome, SAPHO syndrome, and XYY syndrome. Attention is also paid to adequate treatment which not only has to comply with combined systemic and topical therapy, but in some cases also requires surgical treatment. The paper includes an overview of the most important systemic drugs used for the treatment of both moderate and severe acne. (author)

[en] The bovine dermatofilosis is an excudative and enzootic dermatite found in many livestock production area of in Angola. There is not limit of altitude and longitude to the presence and extend of the disease. A study carried out during the last five years with support of the Veterinary Services demonstrated the presence of the diseases on Northern, Central and Southern provinces of Angola with altitudes from 200 m to 2,000 m. Annual rainfall has real influence on the evolution of the disease. Disease Incidence: Among other animal diseases the dermatofilosis has an economical importance in the government restocking programme dues to its losses. Affected animals generally are in bad conditions and it is registered a decrease of productivity in term of meat, milk and drought powder. Sometimes the infection is associated to other skin diseases such as mange (Demodex spp). In all cases the incidence of the disease is more than 60% in reference to mange, lumpy skin and mycosis. Routine Diagnosis: The routine diagnosis is made by the Veterinary Services Field Personnel and confirmation is made in the four Laboratories of the Veterinary Research Institute (IIV), located in Cabinda, Luanda, Wako Kungo and Lubango. The clinical lesions are typical and assistance is provided to Field teams to recognize them during their activities (cattle dipping, treatment and vaccination campaign). OIE recommended techniques are used in IIV Laboratories. Treatment and Control: Animal dipping is practiced but not always efficient and experiment treatments are made in some commercial farms. The inexistence of curative treatment for most of the small holders is a big constraint to livestock development and rural families income. To alleviate this situation, the Veterinary Services have undertaken control regulations in term of quarantine and restrictions of animal movements in accordance to OIE rules. More engagement of this is necessary to reduce the incidence of the disease. Disease Prevalence: Most of the cases of the disease are found in small holders, a few in commercial farms. The prevalence is between 10 to 50 % in the herds. Without treatment this prevalence always increases with pick in rain season. No significance difference was registered in reference to breed susceptibility (local or imported) and animal category. The disease lesions progress quickly and prognostic is always fatal.The disease is as a matter of concern

[en] Twenty patients with photodermatoses [actinic prurigo (n = 6), hydroa vacciniforme (n = 4), idiopathic solar urticaria (n 1), amiodarone-induced photosensitivity (n = 1) and a range of cutaneous porphyrias (n = 8)] were treated with a ''hardening'' course of narrow-band ultraviolet B (TL-01) phototherapy in springtime. The response to phototherapy was monitored subjectively, by interviewing patients after the summer, and objectively by monochromator phototesting, before and after phototherapy. Fifteen patients reported that treatment was worthwhile. Monochromator phototesting after phototherapy revealed a fourfold increase in the minimal erythema dose in those with abnormal photosensitivity to ultraviolet A wavebands. Adverse effects included erythema (seven patients), pruritus (five) and provocation of the eruption (four). We now routinely consider narrow-band UVB phototherapy for problem photodermatoses.

[en] In the article is summarized the rise of the pigmentation, its distribution and solution by laser. When the laser therapy is recommended for pigment spots, first it is important to have the right diagnosis, which we can check by biopsy examination followed by histopathological verification (result of histopathological examination), if necessary. For the therapy of pigmented lesions we mostly use Q-S (switched) lasers, which work on principle of selective phototermolysis and cause photodysruption of melanin or pigment. (author)

[en] Objective: To assess the pattern of cutaneous changes and associated disorders in patients with hyperthyroidism. Study Design: Cross-sectional Study. Place and Duration of study: Department of dermatology and Thyroid Clinic, Mayo and Jinnah Hospitals, Lahore during the period of one year from December, 1997 to December, 1998. Subject and Methods: 50 diagnosed cases of hyperthyroidism (44 females and 6 males of age ranging 21-40 years) were examined in detail for cutaneous changes and associated disorders. Results: Dermatological abnormalities were observed in 96% patients. Common manifestations of hyperthyroidism were altered skin texture in 48 (96%) and increased skin temperature in 46 (92%) patients. Other cutaneous findings included hyperhidrosis in 34(68%), generalized pruritus in 15 (30%), hyperpigmentation in 15 (30%) and pre tibial myxedema in 2 (4%) patients. Hair and nail changes were observed in 36 (72%) and 25 (50%) patients, respectively. Other associated autoimmune diseases seen were urticaria in 20 (40%) vitiligo in 12 (24%) alopecia areata in 4 (8%) and systemic lupus erythematosus in a 2% patient. Pustulosis palmoplantar is and xanthelasma were seen in one patient each. Conclusion: cultaneous examination can provide important clues to the diagnosis of hyperthyroidism. (author)

[en] We report the CT and MRI findings in a 5-year-old girl with histologically proven frontosphenoidal dumbbell-shaped dermoid cyst with sinus tracts in the frontal bone extending to the dura. Although the most common location for dermoid cyst in the head and neck is at the frontosphenoidal region, presentation with a tract extending deep to underlying bone or the intracranium is rare for this location. Complete surgical excision has been widely accepted as the basic treatment for dermoid cyst. However, the relatively extensive nature of such surgical interventions may be associated with serious risks to both visual acuity and cosmesis. From a clinical viewpoint, even if these are rare cases, radiological imaging is crucial for orienting the deeper extension of the lesion for presurgical planning. (orig.)
