Effect of isoflurane anaesthetic time on ocular a-scan ultrasonography measures and their relationship to age and OCT measures in the Guinea pig.

A-scan ultrasonography enables precise measurement of internal ocular structures. Historically, its use has underpinned fundamental studies of eye development and aberrant eye growth in animal models of myopia; however, the procedure typically requires anaesthesia. Since anaesthesia affects intra-ocular pressure (IOP), we investigated changes in internal ocular structures with isoflurane exposure and compared measurements with those taken in awake animals using optical coherence tomography (OCT).

Neonatal Feeding Intolerance and Its Characteristics: A Descriptive Study.

Background:  Feeding intolerance (FI) is common in preterm infants leading to feeding and gastrointestinal disruptions. FI in newborns can be a sign of a variety of problems, ranging from minor, self-limiting illnesses to serious ones. Many causes are found to cause FI such as low intestinal motility, bacterial colonization, hormonal response, and local immunity response.

Idiopathic true ulnar artery aneurysm.

Introduction And Importance: True ulnar artery aneurysms are a rare entity, with existing literature suggesting that most of these aneurysms are due to trauma. This case report sheds light on a true ulnar artery aneurysm that was deemed to be idiopathic.

Case Presentation: A 49-year-old lady presented with numbness in the medial 3 fingers of the left hand, tenderness over the medial forearm, and a palpable ulnar artery pulse.

Epidemiology of Malaria in the State of Qatar, 2008-2015.

Background And Objectives: Imported malaria poses a serious public health problem in Qatar because its population is "naïve" to such infection; where local transmission might lead to serious, life-threatening infection and might even trigger epidemics.

Methods: This study is a retrospective review of the imported malaria cases in Qatar reported by the malaria surveillance program at the Ministry of Public Health (MoPH), during the period between January 2008 and December 2015. All cases were imported and underwent parasitological confirmation through microscopy.
