Peroral endoscopic myotomy (POEM) for the treatment of achalasia: A multicenter Middle Eastern experience.

Background: Peroral endoscopic myotomy (POEM) was proposed in 2010 as a minimally invasive procedure for the treatment of achalasia. In this article, we describe the Middle Eastern experience with the procedure in terms of efficacy, length of admission, and short- and long-term complications.

Methods: A retrospective analysis of our prospectively collected data on patients who underwent a POEM procedure was conducted between March 2019 and May 2020.

Liver diseases in pregnancy and outcomes: A retrospective study from Saudi Arabia.

Liver diseases unique to pregnancy are common causes of both maternal and fetal mortality and morbidity. We retrospectively studied liver diseases unique to pregnancy, including hyperemesis gravidarum (HG); intrahepatic cholestasis of pregnancy; eclampsia; preeclampsia; hemolysis, elevated liver enzymes, and a low platelets (HELLP) syndrome; and acute fatty liver of pregnancy. We collected data including maternal age, gestational weeks at presentation and at delivery, mode of delivery, number of parity, and laboratory markers at 0, 1 week, and within 24 hours after delivery; from 112 patients (mean age, 29.

Pregnancy-associated hemolytic uremic syndrome.

Pregnancy-associated hemolytic uremic syndrome (P-aHUS) is not an uncommon condition. It is considered a medical emergency that is associated with a high risk of mortality and serious morbidity. End-stage renal disease as a consequence of P-aHUS occurs in >50% of the patients if left untreated; the majority of identified cases (79%) are during the postpartum period.

Prevalence and Clinical Characteristics of NAFLD in Chronic Liver Disease Patients from King Abdulaziz University Hospital, Jeddah.

Background: Nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease (CLD). NAFLD is also related to obesity and metabolic syndromes, which are common in Saudi Arabia. However, it is yet unclear what proportion of CLD cases is because of NAFLD in Saudi Arabia.

Three months interval therapy of Eculizumab in a patient with atypical hemolytic uremic syndrome with hybrid CFHR1/CFH gene.

Pregnancy-associated atypical hemolytic uremic syndrome (P-aHUS) is a rare condition. It is characterized by very high maternal mortality and morbidity. Most cases of P-aHUS (79%) manifest in the postpartum period; this is probably due to the complement's involvement in aHUS pathogenesis.

Dengue fever. Clinical features of 567 consecutive patients admitted to a tertiary care center in Saudi Arabia.

To delineate the clinical features and outcomes of dengue infection and to guide clinician of early diagnosis and identification of risks factors for dengue hemorrhagic fever. Methods: This study is a retrospective cross-sectional. Clinical records of 567 patients with a confirmed diagnosis of dengue infection, admitted to a single hospital in Jeddah, Saudi Arabia, between January 2010 and  June 2014 were reviewed.

In silico Prediction and Docking of Tertiary Structure of LuxI, an Inducer Synthase of Vibrio fischeri.

Background: LuxI is a component of the quorum sensing signaling pathway in Vibrio fischeriresponsible for the inducer synthesis that is essential for bioluminescence.

Methods: Homology modeling of LuxI was carried out using Phyre2 and refined with the GalaxyWEB server. Five models were generated and evaluated by ERRAT, ANOLEA, QMEAN6, and Procheck.
