Treatment Resistant Epilepsy in Autism Spectrum Disorder: Increased Risk for Females.

The male:female ratio in autism spectrum disorder (ASD) averages greater than 4:1 while the male:female ratio of ASD with epilepsy averages less than 3:1. This indicates an elevated risk of epilepsy in females with ASD; yet, it is unknown whether phenotypic features of epilepsy and ASD differ between males and females with this comorbidity. The goal of this study is to investigate sex differences in phenotypic features of epilepsy and ASD in a prospective sample of 130 children and young adults with an initial ASD diagnosis and subsequent epilepsy diagnosis.

Complement factor B activation in patients with preeclampsia.

Preeclampsia is a leading cause of maternal and fetal morbidity and mortality. Bb, the active fragment of complement factor B (fB), has been reported to be a predictor of preeclampsia. However, conflicting results have been found by some investigators.

A case of multisystem endometriosis.

Catamenial pneumothorax is a rare complication secondary to pleural endometriosis. We present a case of a 37-year-old-female with a history of recurrent pneumothoraces with an associated temporal relationship to the onset of her menses. In addition to her recurrent pneumothoraces, on further evaluation, she was found to have multiple nodular masses within the omentum.

Paranasal sinus involvement in metastatic carcinoma.

Metastatic carcinoma involving the paranasal sinuses is uncommon. One hundred-sixty seven cases have been published in the literature since 1951. Symptoms, signs, and rhinoscopic and imaging findings are often nonspecific, and the diagnosis may be missed for considerable time.

Metastatic prostate carcinoma mimicking primary anal cancer.

A 71-year-old man with a history of castration-refractory prostate cancer was initially treated with hormonal therapy. He responded with a decreasing prostate-specific antigen level and improved symptoms. Chemotherapy was initiated later, after an increasing prostate-specific antigen level and findings of distant metastases.
