Seasonal allergic rhinitis (SAR) is common in adolescents. However, few studies have investigated the effectiveness of intranasal corticosteroids (INSs) for nasal and ocular symptoms of SAR solely in adolescents. The purpose of this study was to determine the safety and efficacy of the INS mometasone furoate nasal spray (MFNS) in adolescents; a post hoc analysis was conducted of adolescents who had participated in a study with adults. Data were analyzed retrospectively for subjects aged 12-17 years with moderate or severe SAR randomized to mometasone furoate, 200 mcg once daily (n = 86), or placebo (n = 82) for 15 days in a multicenter, double-blind, placebo-controlled study. Symptom scores (0 = none to 3 = severe) were recorded in diaries twice daily. End points included changes from baseline in total nasal symptom score (TNSS), individual nasal symptom score (rhinorrhea, congestion, itching, and sneezing), and total ocular symptom score (TOSS). Over 15 days, a significantly greater decrease from baseline in mean TNSS was observed in subjects receiving mometasone furoate (-2.47; -28.8%) compared with those receiving placebo (-0.9; -9.6%; p < 0.001). Significant improvement versus placebo was seen for each full day of treatment. Mometasone furoate significantly improved individual nasal symptoms (p < or = 0.03) and TOSS (p = 0.011) versus placebo. The incidence of adverse events was similar for both treatment groups. MFNS, 200 mcg once daily, is an effective and well-tolerated treatment for symptoms of SAR in adolescents.

A need exists for safe, effective therapy for the relief of the symptoms of allergic rhinitis (AR) that also consistently relieves nasal congestion, the most common and bothersome symptom. This study was performed to assess efficacy and safety of a once-daily tablet containing 10 mg of loratadine, an antihistamine, and 10 mg of montelukast, a leukotriene antagonist (SCH 445761) versus placebo and pseudoephedrine (PSE; 240 mg once-daily formulation; active comparator). In a multicenter, parallel-group, double-blind, double-dummy, randomized study, 1095 subjects with documented history of seasonal AR and positive skin-prick test to a prevailing aeroallergen were treated for 15 days with fixed-dose combination loratadine/montelukast (L/M), PSE, or placebo. After randomization, subjects rated severity of nasal congestion and measured peak nasal inspiratory flow (PNIF) rate in the morning and evening. The change in quality of life from baseline was also assessed. L/M and PSE were significantly more effective than placebo in alleviating nighttime and daytime nasal congestion and improving PNIF rate, an objective measure of nasal obstruction. There were no significant differences between L/M and PSE for any efficacy analysis including improvement in the quality of life. Subjects treated with L/M experienced a similar incidence of total adverse events versus placebo and a lower incidence of total adverse events (including dizziness, insomnia, jitteriness, nausea, and dry mouth) versus PSE. Nasal decongestant activity of L/M was significantly higher than that of placebo and similar to that of PSE in symptomatic AR subjects. L/M showed a safety profile similar to placebo and was better tolerated than PSE. Thus, L/M offers a safe and efficacious alternative to PSE for the treatment of nasal congestion associated with AR.

A 64-year-old man presented with a superficial, well-demarcated, skin-colored tumor on the left posterior scalp that measured 4 x 5 x 6 cm. The tumor was nearly hairless, rubbery, non-tender, and mobile over the underlying subcutaneous tissues. The lesion had grown slowly since arising approximately 30 years ago. Treatment options were declined in the past. However, with relatively more rapid growth over the past five years, the nodule began to cause intermittent pain and interfere with the patient's ability to lie on his back. The patient denied a history of similar lesions in himself or his family. A biopsy specimen showed a ruptured proliferating trichilemmal cyst with focal calcification. Complete excision is recommended for all benign proliferating variants owing to their potential for locally aggressive behavior and malignant transformation

A 42-year-old man presented with a six-month history of a slowly-enlarging ulcer on his right sole, a 30-year history of altered pigmentation of the trunk and extremities, and hyperkeratotic papules of the palms and soles. Histopathologic examination showed an invasive squamous-cell carcinoma of the right sole and hyperkeratosis with keratinocyte atypia of the left finger and left lateral foot. The clinical and histopathologic findings are consistent with chronic arsenicism, which most commonly occurs in the setting of drinking contaminated water or after occupational exposure. Evaluation should include a physical examination, basic laboratory work-up, and measurement of a 24-hour urine arsenic concentration. Vigilant surveillance for the development of cutaneous malignancies is required. Oral retinoids may be helpful in reducing hyperkeratosis secondary to chronic arsenicism

A 59-year-old man presented with a well-demarcated, tender ulcer at the base of the penile shaft that had been present for approximately five years. The ulcer had been responsive neither to topical antibacterials, antifungals, and glucocorticoids nor to oral acyclovir. A biopsy specimen showed an intra-epidermal neoplasm consistent with extramammary Paget disease (EMPD) based on light microscopy and immunohistochemistry. Patients with EMPD require extensive medical evaluation because of its association with adnexal carcinoma and visceral malignant conditions. Evaluation should include a full body skin and lymph node examination, colonscopy, cystoscopy, and sex-specific studies including pelvic and breast examinations, with imaging for women and prostate examination with prostate specific antigen levels for men. Close monitoring after treatment is important because of the recognized risk of recurrence and malignant conditions
