[Squamous cell carcinoma of the breast: a case study conducted in Mauritania].

Primary epidermoid carcinoma (PEC) also known as squamous cell carcinoma of the breast is a rare tumor accounting for 0.1% to 2% of all breast cancers. It is a metaplastic carcinoma; its histogenesis and prognosis are controversial as well as its clinical and mammographic appearances which are not characteristic compared to other cancers.

Mortality rate of ICU patients with the Middle East Respiratory Syndrome - Coronavirus infection at King Fahad Hospital, Jeddah, Saudi Arabia.

Objective: The Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is a novel coronavirus circulating in the Arabian Peninsula since September 2012. It leads to significant respiratory disease and among patients with co-morbidities is associated with high mortality. This research studied the mortality rate of MERS-CoV among intensive care unit (ICU) patients and the correlation of mortality with different co-morbidities.

Extracorporeal membrane oxygenation for severe Middle East respiratory syndrome coronavirus.

Background: Middle East respiratory syndrome (MERS) is caused by a coronavirus (MERS-CoV) and is characterized by hypoxemic respiratory failure. The objective of this study is to compare the outcomes of MERS-CoV patients before and after the availability of extracorporeal membrane oxygenation (ECMO) as a rescue therapy in severely hypoxemic patients who failed conventional strategies.

Methods: We collected data retrospectively on MERS-CoV patients with refractory respiratory failure from April 2014 to December 2015 in 5 intensive care units (ICUs) in Saudi Arabia.

Persistence of otoacoustic emissions in children with auditory neuropathy spectrum disorders.

Objectives: Many studies confirmed the disappearance of otoacoustic emissions in some of the patients with auditory neuropathy spectrum disorder, yet the data about the incidence rate of such disappearance is scanty or even absent. This study aims to test the persistence of transient evoked otoacoustic emissions in patients with auditory neuropathy spectrum disorder over few years.

Methods: The study group consisted of 77 subjects (31 females and 46 males).

Enantioselective total synthesis and X-ray structures of the tetrahydroprotoberberine alkaloids (-)-(S)-tetrahydropalmatrubine and (-)-(S)-corytenchine.

Enantioselective total syntheses and X-ray structures of both (S)-tetrahydropalmatrubine (2) and (S)-corytenchine (3) are reported for the first time. They were both derived from (S)-N-norlaudanidine, a benzyltetrahydroisoquinoline that was synthesized with high (>95% ee) enantioselectivity using a chiral auxiliary-assisted Bischler-Napieralski cyclization/reduction approach.

Prevalence and risk factors of hearing impairment among primary-school children in Shebin El-kom District, Egypt.

Purpose: This study examined the feasibility of screening hearing loss in rural and urban schools in Egypt, and investigated the prevalence and causes of hearing impairment (HI) in Egyptian primary-school students.

Method: A total of 555 children (6-12 years of age) from a rural and an urban school in the Shebin El-Kom District of Egypt were screened for HI at their schools. A 2-stage screening procedure was used, and positive cases were referred for a diagnostic hearing assessment at a regional medical facility.

[2,2'-Imino-diethano-lato(2-)-κO,N,O'][4-(meth-oxy-carbonyl-meth-yl)phen-yl]boron.

The title compound, C(13)H(18)BNO(4), was readily obtained from the reaction of methyl 4-boronobenzene acetate with ethano-lamine. A combination of inter-molecular N-H⋯O hydrogen bonds and C-H⋯π inter-actions leads to the pairwise association of mol-ecules.

Stroke in CT-scan Department of Khartoum Hospital, Sudan.

Prospective data were collected on consecutive patients admitted to Khartoum Teaching Hospital with a diagnosis of stroke. Risk factors and clinical characteristics were assessed by neurological examination and computed tomography scan. A total of 128 patients were enrolled in the study, of whom 74 (57.
