TL;DR: BRP may be attributed to a neuropathy, such as chronic cervical radiculopathy, and the possibility of an underlying neuropathy should be considered in the evaluation and treatment of all patients with BRP.
Abstract: Background: Brachioradial pruritus (BRP) is a localized pruritus of the dorsolateral aspect of the arm. BRP is an enigmatic condition with a controversial cause; some authors consider BRP to be a photodermatosis whereas other authors attribute BRP to compression of cervical nerve roots. Objective: We sought to investigate the presence of neuropathy in patients with BRP. Methods: We performed electrophysiologic studies of the median, ulnar, and radial nerves in consecutive patients with BRP, including measurement of sensory and motor distal latency, conduction velocity and F responses of the median and ulnar nerves, and sensory distal latency of the radial nerves in both upper limbs. Results: Included in the study were 7 patients, 5 men and 2 women, with an average age of 58.3 years (range: 42-72 years). Of the patients, 4 (57%) had abnormal F responses that were diagnostic for cervical radiculopathy, and 3 of these patients had prolonged distal latencies of the nerves tested, which may be interpreted as sensory motor neuropathy secondary to chronic radiculopathy. The fourth patient had polyneuropathy secondary to diabetes mellitus. Conclusion: BRP may be attributed to a neuropathy, such as chronic cervical radiculopathy. The possibility of an underlying neuropathy should be considered in the evaluation and treatment of all patients with BRP. (J Am Acad Dermatol 2003;48:825-8.)

TL;DR: In conclusion, incomplete excision of BCCs was associated with location of the tumors in the eyelids, ears, naso-labial folds and nose, and it is recommended that in patients with BCCs located in these sites, surgeons should commence particular surgical measures to avoid inadequate excision.
Abstract: Incomplete excision of basal cell carcinomas (BCCs) may be followed by recurrence of the tumor. In order to detect risk factors for incomplete excision of BCCs we performed a cross-sectional study of 1278 patients who underwent a primary excision of BCCs, during a four-year period, within an ambulatory and hospital plastic surgery department setting. Incomplete excision occurred in 159 of 1478 primary excisions of BCCs (10.8%) and was significantly associated with location of the tumors in the eyelids (OR 3.64, 95% CI 1.96-6.71), ears (OR 2.51, 95% CI 1.25-4.94), naso-labial folds (OR 2.26, 95% CI 0.99-5.04) and nose (OR 1.88, 95% CI 1.30-2.71). There was an inverse association with location of the tumors in the upper limbs (OR 0.44, 95% CI 0.21-0.90), back (OR 0.12, 95% CI 0.02-0.48) or chest (OR 0.09, 95% CI 0.00-0.57). Baso-squamous differentiation was associated with incomplete excision of BCCs (p = 0.03). No association was observed between incomplete excision of BCCs and gender, age, setting of the operation (ambulatory vs. hospital), clinical appearance of the lesion (suspected BCCs vs. other diagnoses) or diameter of the lesions. In conclusion, incomplete excision of BCCs was associated with location of the tumors in the eyelids, ears, naso-labial folds and nose. We recommend that in patients with BCCs located in these sites, surgeons should commence particular surgical measures to avoid inadequate excisions of the tumors.

TL;DR: This paper proposes a new cohort selection method called the Close Impostor Clustering (CIC), which is shown to outperform several other methods in a text-dependent verification task.
Abstract: Speaker verification systems require some kind of background model to reliably perform the verification task. Several algorithms have been proposed for the selection of cohort models to form a background model. This paper proposes a new cohort selection method called the Close Impostor Clustering (CIC). The new method is shown to outperform several other methods in a text-dependent verification task. Several normalization methods are also compared. With three cohort models and the best scorenormalization method, the CIC yielded an average Equal Error Rate (EER) of 0.8%, while the second best method (Maximally-Spread Close, MSC) yielded average EER of 1.1%.

TL;DR: Mycological cure proportions were not statistically significant between patients treated by terbinafine or itraconazole for toenail onychomycosis, however, better subjective outcome measures indicated an advantage for terbINAfine over itraconsole, noticeable in females and patients 55 years old and above.
Abstract: BACKGROUND: Previously, sponsored publications have shown that either terbinafine or itraconazole (pulse regimen) are effective for patients with toenail onychomycosis. However, independent comparative studies are lacking.OBJECTIVES: To objectively compare treatment with terbinafine and itraconazole in patients with toenail onychomycosis.METHODS: The effectiveness of terbinafine (250 mg/day 3 months) versus itraconazole pulse regimen (400 mg/day for the first week of each month, for three cycles) was retrospectively evaluated in patients with toenail onychomycosis using mycological tests and subjective outcome measures. Statistical analyses were performed using one‐way analyses of variance (ANOVA) for continuous variables and Fisher exact tests for categorical variables.RESULTS: Included in the study were 117 patients (74 patients treated by terbinafine and 43 patients treated with itraconazole). Patients were examined at an average period of 20 months after the end of therapy. Mycological cure was observ...

TL;DR: This work describes multiple agminated trichodiscomas in the earlobe, which may occur as isolated tumors or in association with other follicular tumors.
Abstract: Trichodiscomas are hamartomas of the hair disk and appear as multiple, firm, well-circumscribed papules measuring a few millimeters. In most cases, trichodiscomas are distributed on the face and neck. Trichodiscomas may occur as isolated tumors or in association with other follicular tumors. In some cases, multiple trichodiscomas appear in association with fibrofolliculomas or acrochordons. We herein describe multiple agminated trichodiscomas in the earlobe.

TL;DR: A discrepancy exists between the high proportion of appropriate soldiers' referrals to the ED and the low hospitalization proportion, and organizational steps should be undertaken in the Israel Defense Force to decrease excess military use of civilian ED services.
Abstract: Background: Emergency departments (ED) in Israel deal with a large number of referrals from the Israel Defense Force. In a recent study, we observed that only 3% of soldiers referred to the ED in Soroka Medical Center were hospitalized. Objectives: The purpose of this study was to determine the appropriateness of soldier referrals to the ED, using a proposed set of criteria for ED appropriateness. Methods: A retrospective assessment of 707 discharge letters of soldiers from the ED was performed. A set of criteria to assess the appropriateness of soldier's referrals to the ED was developed. The criteria were as follows: (1) resuscitation, (2) hospitalization, (3) laboratory examination, (4) X-ray examination, (5) medical treatment, and (6) specialist consultation. A referral was considered appropriate if at least one criterion was positive. Results: According to the proposed criteria of ED military appropriateness, 586 of 707 referrals (83%) were considered as appropriate. Appropriateness of the referrals according to sections of the ED was as follows: orthopedics (97%), internal medicine (63%), ophthalmology (100%), and neurosurgery (100%). Conclusions: A discrepancy exists between the high proportion of appropriate soldiers' referrals to the ED and the low hospitalization proportion. Organizational steps should be undertaken in the Israel Defense Force to decrease excess military use of civilian ED services.
