We report a case of myiasis caused by larvae of Dermatobia hominis in a 12-year-old boy. The infestation was acquired in Uruguay and was characterized by a single, large, inflammatory, nodular lesion located on the scalp. The lesion was accompanied by local pruritus and pain as well as diffuse headache and regional lymphadenopathy. From the lesion a single larva in stage III, of noteworthy size, was removed. Very few pediatric cases of myiasis due to D. hominis have been reported in the literature. Furthermore, as far as we know, just one adult case of myiasis caused by D. hominis acquired in Uruguay has been published.

Sixteen patients up to 18 years of age with widespread alopecia areata (AA) were recruited for the study. They included 10 patients with extensive AA (> or = 40% loss of scalp hair and or more than 10 patches scattered over the scalp and body) and 3 each with alopecia totalis and circumscribed alopecia areata. Patients were divided into two groups. In group A, aged 12 to 18 years, patients received 300 mg of prednisolone in a monthly oral pulse; in group B, aged 3 to 11 years, patients received betamethasone sodium phosphate as soluble tablets or syrup equivalent to prednisolone 5 mg/kg body weight every month. The pulsed doses of corticosteroid were continued for a minimum of three doses or until cosmetically acceptable hair growth was obtained. All patients but one 5-year-old girl received a minimum of three doses. Excellent hair growth was obtained in 9 (60%) of 15 patients evaluated at 6 months. Four patients out of 13 (>12 month follow-up), including two each in group A and B, developed a localized relapse during mean follow-up of 16.4 and 33.7 months in group A and B, respectively. Side effects of pulsed corticosteroid were minimal and were recorded in two patients (transient giddiness and headache, epigastric burning in one each). We recommend pulsed doses of prednisolone as one of the modalities in the treatment of widespread AA in young patients, including children.

The present article illustrates the effects of low dose botulinum toxin (BTx) injections for the improvement of hyperkinetic facial lines and presents a grading treatment chart designed to standardize the reporting of the improvement seen. A questionnaire of patient acceptance, the patients' impression of therapy and short-term results and complications are reported. Twelve patients with 26 injected-paired regions were charted and the response to injection was graded. Patients had hyperkinetic facial lines in glabella, periorbital regions or horizontal forehead lines. Diluted BTx type A (1 IU/0.1 mL) was injected and patients were assessed at 10 days. A second follow up injection was offered to patients at this stage if required. Objectively, all patients' hyperkinetic actions and lines improved or diminished. The degree of improvement was similar in all areas injected and a symmetry of results was always observed. In a minority of cases, all movement was lost (7/26) and in others it was weakened but present (19/26). In some injected areas the actual expression line that was visible at rest disappeared entirely (11/26): in the others it was diminished (15/26). Complications were few. Two patients had temporary brow ptosis that spontaneously recovered within the first week. No eyelid ptosis was noted. Bruising and headaches were the most common reported complications. Low dose BTx is an effective and well-tolerated treatment for hyperkinetic facial lines with few significant complications in this small pilot study. The grading chart may allow easier comparisons of results between studies on the effects of BTx therapy.

Three patients, negative for human immunodeficiency virus (HIV), with histologically and polymerase chain reaction-proven non-HIV Kaposi's sarcoma who received low-dose interferon (IFN) as first-line treatment because of disseminated symptomatic disease are reported. Applying 3-18 million IU of IFN-alpha 2a per day, 3 days a week, subcutaneously for 8-20 months, major responses were achieved in all three cases. Tumour regression was observed within 4 months and has continued for 57 and 18 months to date (cases 1 and 2, respectively). Influenza-like symptoms, including fever, headaches and fatigue, were mild side-effects. However, in the third patient interferon injections had to be stopped because of hepatic enzyme elevation. Including this case report, 27 non-HIV Kaposi's sarcoma patients subcutaneously treated with IFN-alpha have been reported in literature. Most therapy regimens included 3-18 million IU IFN-alpha per day for 3 days a week. Twenty of 27 patients, or 74%, responded to therapy, whereas seven patients or 26% had stable or progressive disease. Relapse after IFN withdrawal can occur but is frequently delayed and limited, as in case 1. Following the response to IFN treatment, human herpesvirus-8 DNA was detected in the blood mononuclear cells of all three patients, possibly contributing to future relapses.

We have previously reported the reduction of cicatricial pemphigoid orodynia with minocycline. Tetracycline combined with high dose nicotinamide has also been beneficial in a number of cutaneous immunological disorders. We now report a series of eight cases in whom further subjective or clinical improvement accrued in five, after the addition of high dose (2.5 or 3 g) nicotinamide to minocycline; however, one of these then discontinued the nicotinamide because of headache and nausea, another was withdrawn from the study because of progressive upper respiratory tract mucosal involvement, and two were changed from minocycline to tetracycline because they developed minocycline-induced hyperpigmentation.

We report the case of a 30-year-old patient who developed scombrotoxic fish poisoning after eating cooked fresh tuna. Symptoms included a bright red rash, tightness of the chest, palpitations, anxiety, mild headache and dizziness, all of which resolved spontaneously within 2-3 h. Such poisoning results from the consumption of spoiled fish of the families Scomberesocidae or Scombridae - in particular tuna, mackerel, skipjack and bonito - which contain high levels of histidine. Incorrect storage of fish allows bacterial histidine decarboxylase to convert histidine to histamine. The ensuing symptoms are thought to result from the ingestion of histamine. Scombrotoxic fish poisoning is preventable by the correct handling and refrigeration of these fish.

A 76-year-old woman with giant cell (temporal) arteritis was described; she presented with a one year history of headache and tinnitus. Histopathological findings from a superficial temporal artery showed arteritis with granulomatous changes. Bilateral carotid arteriograms demonstrated the stenoses of both internal carotid arteries as well as the narrowing of the superficial temporal arteries. Although we dermatologists rarely encounter the disease in daily clinical practice, it is of clinical importance to perform cerebral angiography in patients suspected of temporal arteritis.

A 17-year-old Japanese male was referred with acute urticaria and anaphylaxis after the administration of PL (salicylamide, acetaminophen, anhydrous caffeine and promethazine methylene disalicylate) and Bufferin (aspirin and dialminate) for headache and a high grade fever. The results of prick test, patch test and drug-induced lymphocyte stimulation test with PL and Bufferin were all negative. The patient's peripheral blood mononuclear cells (PBMC) were cultured with or without PL for 72 hours, and the activity of interferon-gamma (IFN-gamma) in the culture supernatant was measured with EIA. A significantly high level of IFN-gamma was detected in PBMC from the patient, but very little in those from healthy control subjects with a history of exposure to PL. This finding may indicate the presence of drug-specific IFN-gamma producing T cells in patients with an anaphylactic shock reaction to medication. Assays that measure the drug-induced IFN-gamma production may thus be a useful diagnostic tool not only for identifying delayed-type hypersensitivity (DTH) to drugs, but also for predicting anaphylactic shock reaction to drugs.

In Korea, Rhus has been used as a folk medicine to cure gastrointestinal diseases and as a health food. We review the clinicopathological and laboratory findings in patients with systemic contact dermatitis caused by intake of Rhus. We reviewed medical records and histopathological sections from 31 patients during a 10-year period. The male/female ratio was 1.4: 1 and the average age was 43.8 years (range 22-70). Ten patients (32%) had a known history of allergy to lacquer. Rhus was ingested to treat gastrointestinal problems including indigestion and gastritis (45%), and as a health food (39%), in cooked meat, in herbal medicine, or taken by inhalation. The patients developed skin lesions such as a maculopapular eruption (65%), erythema multiforme (EM, 32%), erythroderma (19%), pustules, purpura, weals and blisters. Erythroderma was very frequent in patients with a known history of allergy to lacquer, but maculopapular and EM-type eruptions were more frequently observed in those without a history of allergy. All patients experienced generalized or localized pruritus. Other symptoms included gastrointestinal problems (32%), fever (26%), chills and headache; many developed leucocytosis (70%) with neutrophilia (88%), while some showed toxic effects on liver and kidney. Fifty-nine per cent of patients observed cutaneous or general symptoms within a day after ingestion of Rhus. There was no difference in the time lag for symptoms to develop between patients allergic and not allergic to Rhus. All patients responded well to treatment with systemic steroids and antihistamines. Common histopathological findings were vascular dilatation, perivascular lymphohistiocytic infiltration, and extravasation of red blood cells in the upper dermis. Rhus lacquer should not be ingested in view of its highly allergic and toxic effects.

A previously healthy 7-year-old white boy presented to St. Louis Children's Hospital with a 1-day history of headache, malaise, temperature of 38.7 degrees C, and a progressively erythematous, tender calf with central dusky purpura. On the morning of admission, his mother noticed a 2-mm crust on the patient's right calf with a 3-cm x 3-cm area of surrounding erythema. No history of recent trauma or bite was obtained. He had suffered two episodes of nonbloody, nonbilious emesis during the last day. In addition, over the previous 12 h, he presented brown urine without dysuria. His mother and brother had suffered from gastroenteritis over the previous week without bloody diarrhea. On initial physical examination, there was a 6-cm x 11-cm macular tender purpuric plaque with a central punctum on the right inner calf, which was warm and tender to the touch, with erythematous streaking towards the popliteal fossa (Fig. 1). The inguinal area was also erythematous with tender lymphadenopathy and induration, but without fluctuance. Laboratory studies included an elevated white blood cell count of 20, 800/microL with 6% bands, 86% segs, and 7% lymphocytes, hemoglobin of 12.5 g/dL, hematocrit of 35.1%, and platelets of 282,000/microL. The prothrombin time/activated partial tissue thromboplastin was 10. 4/28.0 s (normal PT, 9.3-12.3 s; normal PTT, 21.3-33.7 s) and fibrinogen was 558 mg/dL (normal, 192-379 mg/dL). Urinalysis showed 1+ protein, 8-10 white blood cells, too numerous to count red blood cells, and no hemoglobinuria. His electrolytes, blood urea nitrogen (BUN), and creatine were normal. The urine culture was negative. Blood culture after 24 h showed one out of two bottles of coagulase negative Staphylococcus epidermidis. The patient's physical examination was highly suggestive of a brown recluse spider bite with surrounding purpura. Over the next 2 days, the surrounding rim of erythema expanded. The skin within the plaque cleared and peeled at the periphery. The coagulase negative staphylococci in the blood culture were considered to be a contaminant. Cefotaxime and oxacillin were given intravenously. His leg was elevated and cooled with ice packs. The patient's fever resolved within 24 h. The lesion became less erythematous and nontender with decreased warmth and lymphadenopathy. The child was discharged on Duricef for 10 days. Because the patient experienced hematuria rather than hemoglobinuria, nephritis was suggested. In this case, poststreptococcal glomerulonephritis was the most likely cause. His anti-streptolysin-O titer was elevated at 400 U (normal, <200 U) and C3 was 21.4 mg/dL (normal, 83-177 mg/dL). His urine lightened to yellow-brown in color. His blood pressure was normal. Renal ultrasound showed severe left hydronephrosis with cortical atrophy, probably secondary to chronic/congenital ureteropelvic junction obstruction. His right kidney was normal.
