RESUMO

BACKGROUND AND OBJECTIVE: Rhinophyma is a benign, disfiguring disorder of the nose which presents the end stage of acne rosacea, and can also occasionally result in nasal airway obstruction. We describe the first series of patients treated with Erbium laser. STUDY DESIGN/MATERIALS AND METHODS: Severe-to-moderate rhinophyma in six patients were treated at our institution between 1995 and 1996, using the Erbium:YAG (Erb:YAG) laser. RESULTS: All patients achieved marked cosmetic improvement, with no complications. Post-operative healing time was seven to fourteen days-significantly shorter than similar other modalities. CONCLUSIONS: The Erbium laser provides very accurate tissue ablation and allows the sculpturing of the hypertrophied areas, offering good cosmetic results, with a very short healing period as shown in our study.

RESUMO

BACKGROUND: Mohs surgery and other surgical techniques are used for the removal of squamous cell carcinoma of the lower lip and may leave a large defect in the vermilion and underlying tissue. When nearly the entire lower lip is excised, reconstruction of this defect is a challenge. Repair requires the matching of vermilion color, maintenance of oral sphincter function and mouth opening size, and retention of sensation. Several techniques have been suggested. We present a modification of the Webster flap for total lower lip reconstruction using innervated muscle-bearing flaps. OBJECTIVE: To present a surgical technique for the reconstruction of total lower lip defects after excision of squamous cell carcinoma. METHODS: Innervated muscle-bearing flaps are used and demonstrated in one case. The surgical technique is discussed in detail. RESULTS: The reconstructive results were excellent. There were no postoperative complications. CONCLUSION: The use of innervated muscle-bearing flaps is a useful and effective option for the reconstruction of total lower lip defects.

RESUMO

BACKGROUND: The nasolabial flap is a versatile and effective option for the closure of nasal defects of the cheek and nasal sidewall following Mohs surgery. However, both extirpation of a tumor in the region of the base of the flap or previous use of the flap often destroy the proximal axial blood supply to the flap, excluding its immediate utilization. We describe a different use of the nasolabial flap and a technique for preserving its capacity in the case of reutilization OBJECTIVE: To describe the versatility of the nasolabial flap and a delay procedure that enables its exploitation despite prior disruption of the proximal blood supply. METHODS: Three different uses of the same nasolabial flap are demonstrated in one patient. The surgical techniques are discussed in detail. RESULTS: The reconstructive results were excellent. There were no postoperative complications. CONCLUSION: The nasolabial flap is a versatile and effective option for the closure of nasal defects of the cheek and nasal sidewall. When the nasolabial flap has been used before, or its blood supply compromised, the delay procedure can reestablish its applicability.

RESUMO

BACKGROUND: Photodynamic therapy (PDT) with topical application of 5-aminolevulinic acid (ALA) is a new and effective modality for treatment of superficial basal and squamous cell carcinomas. OBJECTIVE: We present the kinetics of ALA-induced protoporphyrin IX (PP) accumulation and the results of ALA PDT treatment on two patients with different stages (stage I and stage III) of mycosis fungoides (MF)-type cutaneous T-cell lymphoma (CTCL). METHODS: ALA-Decoderm cream was applied to the lesions for 16 hours. Spectrofluorescence measurements of PP accumulation were carried out before, during, and 1 hour after photoirradiation (580-720 nm) using the VersaLight system. RESULTS: Different patterns of PP fluorescence kinetics were observed in patients with early and advanced stages of the disease. During photoirradiation the intensity of fluorescence decreased depending on the lesion thickness. One hour after the photoirradiation procedure no PP fluorescence was observed in the stage I MF lesion, while in the thick stage III MF lesions, PP fluorescence reappeared; after an additional 10-15 minutes of irradiation PP fluorescence disappeared. Complete response with excellent cosmetic results was observed in the stage I lesion after a single irradiation with a light dose of 170 J/cm2; in five stage III lesions, complete response was achieved after fractionated irradiation with a total light dose of 380 J/cm2 (follow-up at 27 and 24 months, respectively). CONCLUSION: The results showed a high response of both stage I and stage III MF lesions to ALA PDT. This modality appears to be very effective and can be used successfully for MF treatment.

RESUMO

The effect of oral theophylline on clinical course, exercise, neuropsychological performance and bronchial reactivity was studied in chronic airflow obstruction. Twelve patients with chronic obstructive pulmonary disease (COPD) [mean age 62.4 +/- 1.6 years (SE), and forced expiratory volume in 1 sec of 1.15 +/- 0.1 l] were randomized to 4 weeks treatment with oral theophylline followed by 4 weeks of placebo, in a double-blind fashion. During each period, patients underwent clinical evaluation, incremental exercise, a battery of neuropsychological tests measuring a wide range of cognitive functions, and an inhaled methacholine provocation. On the active drug (levels 9.5 +/- 1 mg/l), vital capacity and maximal breathing capacity were 16 +/- 7% and 20 +/- 7% respectively, higher relative to placebo (P < 0.04). Exercise capacity, as reflected by peak O2 uptake and the anaerobic threshold, improved 14 +/- 5% and 18 +/- 5% (P < 0.04). In contrast, bronchial responsiveness to inhaled methacholine and the mean scores on the neuropsychological tests were not significantly altered by the drug. Clinical symptoms were unaltered, but mild side effects were more common on theophylline. We concluded that in moderate to severe COPD, theophylline treatment, at the low range of the therapeutic dose, improves lung function and exercise capacity. This improvement is achieved with no detectable alteration of bronchial reactivity to methacholine and with no deleterious effect on cognitive functions.

RESUMO

The pathophysiological mechanisms to explain peritumoral edema have not been clarified. Multiple aspects of brain edema secondary to supratentorial meningiomas were prospectively investigated in a group of 29 patients who underwent surgery consecutively. Sixty-nine tumor samples were analyzed for prostanoid levels. Levels of 6-keto-PGF1 alpha, the stable metabolite of prostacycline, were found to correlate well with the extent of edema (r = 0.51, P < 0.01). The ratio, 6-keto-PGF1 alpha x PGE2/TXB2, was found to have the best correlation with edema index (extension/tumor volume) (r = 0.69, P < 0.005). A case of a hemangiopericytic meningioma with the largest edema extent within the study group also exhibited the highest level of 6-keto-PGF1 alpha (2420 pg/mg protein). Steroid treatment (dosage, duration of therapy, and their product) did not correlate with prostaglandin levels. These findings may explain the inconsistent clinical effects of steroids on meningioma-induced edema. Possible explanations for this phenomenon are discussed. Otherwise, histology, pathological features of tumor aggressiveness, or mechanical parameters, such as its volume, location, and insertion site, did not correlate well with edema parameters or with prostaglandin levels. Similarly, tumor water content, imaging parameters in computed tomography and magnetic resonance, and operative findings (including dissection plane, vascularity, and tumor firmness) did not correlate well with edema parameters. Although a direct cause-effect relationship between prostaglandins and peritumoral edema is not conclusively established, the circumstantial evidence of the ability of prostaglandins to induce vasogenic brain edema and the robust association with peritumoral edema is persuasive.(ABSTRACT TRUNCATED AT 250 WORDS)
