Microsurgical replantation of total upper eyelid avulsion.

We present a unique case in which a dog bite resulted in total full-thickness upper eyelid avulsion in a young Caucasian female. The eyelid was replanted using meticulous microsurgical techniques reanastamosing the arterial supply. To our knowledge, this is the first reported case of a successful microvascular replantation of a completely avulsed upper eyelid. The details of the case and the photographic clinical improvement are described and discussed.

Herpes zoster following cryosurgery.

A 56-year-old man developed reactivation of herpes zoster infection on his right forehead after treatment of several solar keratoses with cryosurgery. The rash was blistering and painful. Treatment with oral aciclovir was instituted and the lesions healed within 2 weeks. Known risk factors for reactivation include age and decreased immunity. Previous case reports have indicated trauma may be a risk factor in herpes zoster. We report a case of herpes zoster as a complication of cryosurgery.

Liposuction for axillary hyperhidrosis.

Excessive axillary sweating is a common problem for which many patients frequently seek dermatological advice. The removal of axillary sweat glands using liposuction with tumescent anaesthesia in an outpatient setting is a relatively short and simple procedure with few complications, as seen in this case series. We present 10 patients treated with axillary liposuction under tumescent anaesthesia. Of the 10 patients treated, four relapsed with axillary hyperhidrosis and required additional liposuction to the same area. The longest time to relapse was 15 months, with 4 months being the shortest time. Six patients have not required additional liposuction, with 7 years being the longest time of remission. The complications reported were bruising in the axillae of two patients and relapse of hyperhidrosis in four patients.

Erythroplasia of Queyrat treated with topical methyl aminolevulinate photodynamic therapy.

An 82-year-old man presented with invasive squamous cell carcinoma of the glans penis arising in erythroplasia of Queyrat. He underwent Mohs' micrographic surgery for the invasive carcinoma. Seven weeks later, the residual erythroplasia of Queyrat was treated using photodynamic therapy. Methyl aminolevulinate cream was applied to the glans of the penis under occlusion for 3 hours and then, after local anaesthesia, irradiated with a 630-nm red-light-emitting diode lamp at a dose of 37 J/cm(2) for 8 min. The patient experienced some mild swelling, redness and pain, which subsided over the following 5 days. Eighteen weeks after photodynamic therapy, there had been no recurrence of the lesion, when the patient died from an unrelated cause.

Papillon-Lefèvre syndrome treated with acitretin.

A 7-year-old boy born to consanguineous parents had suffered from palmoplantar keratoderma and chronic gingivitis since the age of 3 months. He was diagnosed with Papillon-Lefèvre syndrome. Genetic testing confirmed that he was homozygous with a point mutation in exon 6 of the cathepsin C gene. One year after initiating treatment with acitretin 10 mg oral daily and trimethoprim-sulfamethoxazole, the patient's skin remains almost lesion-free, and he has new teeth that erupted during treatment and are free of periodontal disease.

Prurigo nodularis: a review.

Prurigo nodularis is a chronic condition characterized by a papulonodular pruriginous eruption of unknown aetiology. This condition is a difficult disease to treat and causes frustration to both the patient and the treating doctor. A variety of systemic conditions have been reported to be associated with prurigo nodularis. The mechanism by which these disorders may trigger prurigo nodularis is unknown. Nerve growth factor has been implicated in the pathogenesis of prurigo nodularis. Calcitonin gene-related peptide and substance P immunoreactive nerves are markedly increased in prurigo nodularis when compared with normal skin. These neuropeptides may mediate the cutaneous neurogenic inflammation and pruritus in prurigo nodularis. Topical or intralesional glucocorticoids are the treatment of choice. Other topical treatments such as topical vitamin D3, and topical capsaicin have also been reported to be effective. Oral treatments such as cyclosporin and thalidomide have been shown to improve both appearance of the skin and pruritus. We review the clinical features, associations, pathology, pathogenesis and treatment of prurigo nodularis.

Multiple eccrine hidrocystomas.

The clinical and pathological features and treatment of two patients with multiple eccrine hidrocystomas are presented. The first case is characterized by multiple pearly papules with a bluish hue located in the periorbital region and the bridge of the nose. The second case is characterized by multiple, skin-coloured papules located in the periorbital area, forehead, chin and nose. Both were exacerbated by a hot and humid environment. Histopathologically, both demonstrated a unilocular cyst located in the dermis, with a 2-3-layer wall composed of cuboidal epithelium that was non-keratinizing. Treatment with topical atropine sulphate 1% in aqueous solution three times a day was instituted in the first case; however, this was poorly tolerated because of blurred vision and nausea. The lesions were subsequently hyfrecated with a good response. The second case was treated with topical atropine sulphate 1% in aqueous solution three times a day with a good response.
