Of the patients who underwent a retrosigmoid approach, 9 had postoperative audiograms. All of these patients maintained hearing at or near their preoperative level except for 2 patients whose hearing declined and one whose hearing significantly improved.

Conclusion: Hearing preservation

approaches for epidermoids of the CPA is a feasible option for long-term control of these tumors. Resection from a retrosigmoid approach can provide years of useful hearing, and the majority of patients do not require reoperation.”
“Pulmonary arteriovenous malformations (PAVMs) are relatively rare in children. They may occur both as single isolated anomalies and, much more commonly, as one of many widely distributed arteriovenous S63845 malformations (AVMs) in other organs and anatomic locations such as the liver, learn more brain, nose and spine. The latter phenotypically

defines the condition known as Hemorrhagic Hereditary Telengiectasia (HHT). We report a case of a 10 year-old female with an isolated endobronchial right lower lobe PAVM. The patient’s chest radiograph and fine-cut contrast-enhanced CT (CECT) of the neck and thorax were both uncharacteristically normal and, hence, non-diagnostic. Surgical lobectomy was the only means by which to both diagnose and treat this life-threatening condition. This unique case points out the dilemma facing the physician in such a case with only two management options neither of which is ideal: to either obtain a diagnosis with biopsy which is minimally invasive yet life-threatening due to the potential for fatal hemorrhage, or to perform a pulmonary lobectomy which entails removal of an entire lobe of the lung without a pre-operatively confirmed indication to justify the procedure. To our knowledge, this is the first reported case of a child with an endobronchial PAVM who did not carry the diagnosis of HHT, had normal chest radiography, and had a normal fine-cut CEOT of

the neck and thorax where such a management dilemma arose. This case points out that a high index of suspicion for PAVMs must be maintained despite normal chest radiography and CECT of the chest. In such cases, empiric lobectomy becomes the sole therapeutic and definitive diagnostic intervention. We hope that such a case published in the literature serves as a guide to physicians confronting similar circumstances as the rarity of such a constellation Citarinostat of variables precludes higher levels of evidence reporting such as a retrospective case series or prospective randomized controlled clinical trials.

“Objective: Some case reports have suggested primary hyperparathyroidism (PHPT) and peripheral polyneuropathy (PPN) are associated; however, there are no reports of studies examining this possible relationship. The aim of this study was to evaluate peripheral nerve conduction in subjects with PHPT.

Methods: The study involved 17 patients with PHPT. Mean patient age was 60.5 +/- 12.
