Intravenous cidofovir treatment for recalcitrant warts in the setting of a patient with myelodysplastic syndrome

Cidofovir is an acyclic nucleoside phosphonate with broad-spectrum activity against DNA viruses, including human papilloma virus (HPV). However, data on the efficacy of cidofovir in an immunosuppressive setting remain contradictory. We report for the first time on the promotion of the healing of recalcitrant warts in a patient with myelodysplastic syndrome with intravenous cidofovir treatment.     

Double-blind, placebo-controlled comparison of clonazepam and alprazolam for panic disorder

To test the reported antipanic efficacy of clonazepam, the authors randomized 72 subjects with panic disorder to 6 weeks of treatment with either alprazolam, clonazepam, or placebo. Endpoint analysis demonstrated a significant beneficial effect of both active treatments, but not placebo treatment, on the frequency of panic attacks, overall phobia ratings, and the extent of disability. Comparison of the two active treatments revealed no significant differences and no consistent tendency for one agent to be favored over another, although power to detect small differences was limited. Sedation and ataxia were the most common side effects reported, but these effects were mild and transient and did not interfere with treatment outcome. The results of this double-blind, placebo-controlled trial are consistent with previous reports of clonazepam's antipanic efficacy.     

Injury Severity Scores in desert recreational all-terrain vehicle trauma

A retrospective analysis of 1,259 patients injured in all-terrain vehicle accidents over a 2-year period was performed. All patients presented to the same community hospital Emergency Department, located near a major desert off-road vehicle recreational area. The patients were characterized by demographics and Injury Severity Scores. There were 2,149 recorded injuries. Mean ISS +/- standard deviation for all patients was 5.07 +/- 4.93; among patients admitted for inpatient care, 9.83 +/- 6.46. Injury Severity Scores were independent of vehicle type (two, three, or four wheels). In this setting, injuries sustained by children were not disproportionately more severe than those sustained by adults. Where documented, alcohol use was associated with higher ISS, and the use of helmets was associated with less severe head and facial injuries. The most common diagnoses in this series were integumental injuries and fractures, frequently involving the face and extremities.     

Can Electrocardiographic Criteria Predict Adverse Cardiac Events and Positive Cardiac Markers?

OBJECTIVES: To determine electrocardiogram (ECG) predictors of positive cardiac markers and short-term adverse cardiac events in an undifferentiated chest pain population presenting to emergency departments (EDs). The authors hypothesized that specific ECG findings, other than those previously identified in higher-risk populations, would be predictive of cardiac outcomes and positive cardiac markers. METHODS: This study used data from a prospectively collected, retrospectively analyzed Internet-based data registry of undifferentiated chest pain patients (i*trACS). Logistic regression modeling was performed to determine the ECG findings that were predictive of 1) positive cardiac markers and 2) short-term adverse cardiac events. RESULTS: ST-segment elevation (STE), ST-segment depression (STD), pathological Q-waves (PQW), and T-wave inversion were associated with increased odds of percutaneous coronary intervention or catheterization, myocardial infarction, or coronary artery bypass grafting. The odds of creatine kinase-MB (CK-MB) measuring positive were increased if STE, STD, or PQW were present [odds ratio (OR) 2.495, 2.582, and 1.295, respectively]. A right bundle branch block tended to decrease the odds of CK-MB measuring positive (OR 0.658). A similar pattern of results was observed for troponin I (OR 3.608 for STE, 3.72 for STD, 1.538 for PQW). Troponin T showed an increased odds of measuring positive if any of STE, STD, left bundle branch block, or T-wave inversion were evident (OR 2.313, 2.816, 1.80, and 1.449, respectively). CONCLUSIONS: Initial ECG criteria can be used to predict short-term cardiac outcomes and positive cardiac markers. These findings can be important aids in the risk-stratification and aggressive treatment regimens of chest pain patients presenting to EDs.     

Recognizing an index case of type 1 neurofibromatosis.

Neurofibromatosis is a relatively common autosomal dominant disorder with variable penetrance. The disorder usually presents in childhood. Hallmarks of type 1 neurofibromatosis are café-au-lait macules and neurofibromas. Neurologic complications include mental retardation, learning disabilities and seizures. Tumors of the eighth cranial nerve, as well as other intracranial and spinal neoplasms, are the typical lesions in type 2 neurofibromatosis. Both forms of neurofibromatosis have a highly variable course and may result in progressive neurologic deterioration, disfigurement and impingement syndromes. In the 50 percent of cases that represent new mutations, diagnosis may be delayed if the physician is not familiar with the salient features of the disorder. Thorough initial evaluation, genetic counseling and close follow-up are important aspects of management.
