The application of spontaneous corpus cavernosum EMG to assess the status of cavernous smooth muscles, a preliminary study.

Introduction: Diagnostic tests for vascular erectile dysfunction (ED) depend on cavernous smooth muscles (CSM) relaxation following an intracorporal injection (ICI). Enhanced sympathetic tone, which is not uncommon during performance of these tests, can bias its results. Also, CSM diseases can cause veno-occlusive diseases (VOD) ED.

Frontal theta/beta ratio changes during TOVA in Egyptian ADHD children.

Objective: To spot the frontal theta/beta ratio alterations during Tests of Variance of Attention (TOVA) in Egyptian attention deficit hyperactivity disorder (ADHD) children.

Methods: This is a cross sectional study performed in Clinical Neurophysiology Unit, Cairo University, Egypt. It included 2 groups, each of 52 children (one of them with ADHD and the other were normal control).

Pattern sensitivity: a missed part of the diagnosis.

Rationale: Pattern sensitivity can be diagnosed by presenting a series of visual patterns to the subject in the electroencephalography (EEG) laboratory; however, testing for pattern sensitivity is not routinely done during EEG recording. This work aimed to highlight the incidence of pattern sensitivity among patients referred for routine EEG recording during a 1-year period, identifying the cause of referral, diagnosis, and the characteristics of pattern-sensitive patients.

Methods: All patients aged 4 years and older who were referred for routine EEG during a 12-month period and had no motor or visual impairment were enrolled in the study.

Clinical spectrum associated with some structural cerebellar abnormalities.

Objective: To review the clinical, neuroimaging, cytogenetic, and biochemical studies obtained in 20 patients with different cerebellar structural abnormalities presenting at variable ages of onset with variable signs and symptoms.

Methods: These patients visited the Clinical Genetics Department, National Research Center, Cairo, Egypt during the period from September 2002 to September 2003. All patients were subjected to complete personal and family history taking 3 generation family pedigree construction and full clinical examination, including complete eye evaluation.
