Basal cell carcinoma on the eyelids: own experience.

BACKGROUND: Basal cell carcinoma (BCC) is the most common skin malignancy. Eyelids constitute a special location of BCC because of the proximity of the eyeball. OBJECTIVE: This study was undertaken to evaluate the incidence of BCC located on the eyelids, to examine the clinical and histologic types of BCCs in this location, and to present some reconstructive techniques used in the treatment of BCC in palpebral region. METHODS: There were 330 patients with BCC retrospectively included in the study. The comparison was performed between clinical and histologic features of BCCs located on eyelids and in other locations. RESULTS AND CONCLUSIONS: Approximately 16% of all tumors were located on the eyelids. The majority of tumors were situated on the lower eyelid. Noduloulcerative clinical type was observed in 96.3% of tumors. This type was significantly more frequently found on eyelids than on trunk and extremities (p<0.00001). The histologic nodular type was the most common found on eyelids. It was significantly more common on eyelids than on trunk and extremities (p=0.002). The superficial type was significantly less frequently found on the eyelids (p<0.00001). The infiltrative type was significantly more seldom observed on the eyelids compared with other locations of head and neck region (p=0.048). Some technical aspects of reconstructive surgery of the eyelids are presented.

Psoriatic nails: a prospective clinical study.

BACKGROUND: Psoriasis is a widespread skin disorder in which nail involvement is a common symptom. Many psoriatic patients have nail changes morphologically resembling onychomycosis. OBJECTIVE: The present study was undertaken (1) to evaluate the frequency of nail involvement in psoriatic patients, (2) to assess the types of nail changes in psoriasis, (3) to find eventual relationships between nail involvement and some clinical parameters, and finally (4) to determine the prevalence of fungal nail infections in psoriatic individuals. MATERIAL AND METHODS: One hundred six patients hospitalized in our department due to exacerbation of psoriasis participated in the study. Each patient underwent dermatologic examination with special attention paid to the nail changes. In any case of abnormalities clinically suspected of fungal infection, further mycological investigations were performed. RESULTS: Nail changes were present in 83 patients (78.3%) with psoriasis. The most common nail abnormality observed on both fingernails and toenails was subungual hyperkeratosis. Hyperkeratosis, onychorrexis, and discoloration of nail plates were observed significantly more often on toenails. Pitting and longitudinal ridges were significantly more frequent on fingernails. Patients with psoriatic nail dystrophy were significantly older than psoriatic patients without nail abnormalities. Nails were involved statistically more often in patients with arthropathic psoriasis. Positive mycological cultures were obtained from 18% of patients with nail changes. The most commonly isolated fungi were molds. CONCLUSIONS: Dystrophic nails are frequently found in psoriatic individuals, especially those suffering from arthropathic psoriasis. Subungual hyperkeratosis and pitting are the most typical lesions. It is difficult to assess definitively whether psoriasis is a predisposing factor to the development of fungal infections of the nails.

Tanning salons in southwest Poland: a survey of safety standards and professional knowledge of the staff.

BACKGROUND: Nowadays, sunbeds are very popular worldwide; however--in the majority of countries, including Poland--there are no general guidelines and/or regulations for sunbed usage. PURPOSE: The aim of the study was to evaluate tanning salons in southwest Poland, paying special attention to safety regulations and basic professional knowledge of the staff members of these units. The hypothesis was put that tanning salons offer better skin and eye protection if their employees are more educated. METHODS: Fifty-five sunbed units were visited by the investigators, acting as potential clients. Information was obtained from the staff members in response to previously designed questionnaire. RESULTS: Employees of 41.8% of sunbed units had adequate knowledge of radiation used in their establishments. Goggles were provided in 72.7%, sunglasses in additional 25.5% of salons. Lotions with sunscreens were available in 41.8% of units. Brief medical history of the client was taken in 20% of units. No dermatological examination was performed. Tanning salons, where employed staff were well-orientated in ultraviolet radiation emitted in their units, significantly more frequently recommended usage of goggles and sunscreens (P = 0.0037 and P = 0.0033, respectively). Moreover, in these establishments sunscreens were more commonly available (P = 0.0029). CONCLUSIONS: The knowledge of staff members of tanning salons is poor and the eye and skin protection is not enough. The results point out the importance of the knowledge of the staff members in providing skin and eye protection.

Uremic pruritus: a clinical study of maintenance hemodialysis patients.

Uremic pruritus is one of the most bothersome symptoms in patients with chronic renal failure. Its pathogenesis remains unclear. The aim of this study was to evaluate the frequency of uremic pruritus in hemodialysis patients and to correlate its presence and intensity with several clinical parameters. One hundred thirty patients on maintenance hemodialysis were included into the study. The intensity of pruritus was assessed by two methods: visual analog scale and specially adapted questionnaire scoring method. A significantly positive correlation (p < 0.00001) was demonstrated between the two methods for evaluating pruritus. Uremic pruritus was found in 40.8% of patients. An additional 36.1% of patients reported pruritus to have been present in the past during the renal disease period. Itching was generalized in 19% of patients; the remaining subjects suffered from scattered pruritus (50%) or pruritus in a single location (31%). A significant positive relationship (p < 0.02) was demonstrated between the total score of pruritus and duration of the hemodialysis period. Severity of pruritus and sleep disturbance caused by itching also significantly correlated (p < 0.05) with the duration of hemodialysis. Patients hemodialysed on polysulphone membranes more commonly suffered from pruritus than those on hemophane (p < 0.04) or cuprophane (p < 0.03) dialysis membranes. A marked relationship was demonstrated between the intensity of xerosis and prevalence of pruritus. Significantly more patients with very rough skin had pruritus compared to those with rough skin (p < 0.05) and those with slightly dry skin (p < 0.02). Itching was more common in female patients (p < 0.04), but patient age, underlying renal disease and erythropoietin intake did not correlate with the incidence or intensity of pruritus.
