An ingrowing toenail is an excessive lateral nail growth into the nail fold. It acts as a foreign body and exerts a local pressure sore-like effect, which may result in inflammation and granulation. Several treatment modalities exist, including chemical ablation and different surgical procedures. Here we describe and compare a simple and effective method of partial matricectomy using the CO2 laser (group A) versus a similar method with the addition of lateral nail fold vaporization (group B).Outcome evaluation of a modified laser treatment modality for ingrowing toenails and determination of the role of lateral fold vaporization in reducing the recurrence of symptoms.Forty patients (mean age 32.45 years) were treated with CO2 laser ablation of toenails between 1999 and 2005 by four physicians. One physician implemented a method that includes lateral nail fold vaporization and resection of the nail segment with its nail bed from 1999 to 2005. Three physicians implemented a similar technique but without lateral fold vaporization between 1999 and 2003, and added lateral fold vaporization to the performed procedure starting in 2004.The recurrence rate was 37.5% in group A and 6.2% in group B. The overall average disease-free follow-up period was 42.2 months.The use of CO2 laser in the treatment of ingrowing toenails offers an effective modality. We demonstrate the importance of lateral fold vaporization with the CO2 laser both in improving efficacy and in decreasing recurrence rates over a long follow-up period.
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.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).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.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).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.

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)
Foot ulcers carry considerable morbidity in patients with peripheral neuropathy and frequently lead to foot amputation. The purpose of this study was to present our experience treating recalcitrant ulcers underlying the hallux interphalangeal joint in patients with diabetes mellitus (DM)-related neuropathy with a first metatarsophalangeal (MTPJ1) resection arthroplasty.We retrospectively reviewed the computerized medical files of patients with diabetic neuropathy treated with a MTPJ1 resection arthroplasty. We performed 28 arthroplasties on 20 patients with a mean age of 59 years. The patients had a diagnosis of DM for a mean of 10.7 years. Of the ulcers, 26 were grade 1A ulcers, and 2 were grade 2A ulcers (University of Texas score); the ulcer's mean age was 5.4 months. The mean dorsiflexion of the hallux before surgery was 46 degrees.The primary ulcer recovered in a mean of 3.1 weeks. Major complications (wound dehiscence and infection) occurred in 6 of 28 operations. Patients returned to normal activity 4 weeks after all procedures except in the 6 patients with dehiscence. In a subgroup of patients with follow-up longer than a year, the ulcer recurred after 4 of 18 arthroplasties (22%) between 3 and 12 months due to postoperative hallux rigidus. In the remaining 14 of 18 arthroplasties (78%), there was no recurrence during a mean follow-up of 26 months.MTPJ1 resection arthroplasty may be considered in a patient with resistant plantar hallux ulcerations, even in the absence of hallux rigidus. As with all operations on neuropathic feet in patients with DM, the surgeon and the patient should be aware that there is a significant likelihood of complications, but most are treatable.Level IV, case series.
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.
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.
