Clinical and Molecular Characterization of Ataxia with Oculomotor Apraxia Patients In Saudi Arabia

<p>Abstract</p> <p>Background</p> <p>Autosomal recessive ataxias represent a group of clinically overlapping disorders. These include ataxia with oculomotor apraxia type1 (AOA1), ataxia with oculomotor apraxia type 2 (AOA2) and ataxia-telangiectasia-like disease (ATLD). Patients are mainly characterized by cerebellar ataxia and oculomotor apraxia. Although these forms are not quite distinctive phenotypically, different genes have been linked to these disorders. Mutations in the <it>APTX </it>gene were reported in AOA1 patients, mutations in <it>SETX </it>gene were reported in patients with AOA2 and mutations in <it>MRE11 </it>were identified in ATLD patients. In the present study we describe in detail the clinical features and results of genetic analysis of 9 patients from 4 Saudi families with ataxia and oculomotor apraxia.</p> <p>Methods</p> <p>This study was conducted in the period between 2005-2010 to clinically and molecularly characterize patients with AOA phenotype. Comprehensive sequencing of all coding exons of previously reported genes related to this disorder (<it>APTX</it>, <it>SETX </it>and <it>MRE11</it>).</p> <p>Results</p> <p>A novel nonsense truncating mutation c.6859 C > T, R2287X in <it>SETX </it>gene was identified in patients from one family with AOA2. The previously reported missense mutation W210C in <it>MRE11 </it>gene was identified in two families with autosomal recessive ataxia and oculomotor apraxia.</p> <p>Conclusion</p> <p>Mutations in <it>APTX </it>, <it>SETX </it>and <it>MRE11 </it>are common in patients with autosomal recessive ataxia and oculomotor apraxia. The results of the comprehensive screening of these genes in 4 Saudi families identified mutations in <it>SETX </it>and <it>MRE11 </it>genes but failed to identify mutations in <it>APTX </it>gene.</p

Intraperitoneal drain placement and outcomes after elective colorectal surgery: international matched, prospective, cohort study

Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P &lt; 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P &lt; 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk

Inflammatory bowel disease in Bahrain: single-center experience

Maheeba Abdulla,1 Mahmood Al Saeed,1 Rawdha Hameed Fardan,1 Hawra Faisal Alalwan,1 Zahra S Ali Almosawi,1 Amal Fuad Almahroos,1 Jehad Al Qamish2 1Department of Internal Medicine, Salmaniya Medical Complex, Manama, Bahrain, 2Ibn Al Nafees Hospital, Manama, Bahrain Purpose: The number of newly diagnosed inflammatory bowel disease (IBD) cases such as ulcerative colitis (UC), Crohn&rsquo;s disease (CD), and indeterminate colitis (IC) is rapidly increasing in Gulf countries and Saudi Arabia. The aim of this study was to investigate the incidence and prevalence of IBD in patients who have attended the Salmaniya Medical Complex, Bahrain, between the years 1984 and 2014.Patients and methods: All patients who had attended the Salmaniya Medical Complex, Bahrain, and had been diagnosed with UC, CD, or IC, between the years 1984 and 2014, were included in the analysis. Data collected were: patient demographics, symptoms, clinical signs, complications, surgical interventions, extent of disease, endoscopic findings, histopathology, and lab measurements.Results: A total of 187 cases were included; 61 had CD, 123 had UC, and a further 3 cases presented with IC. A clear increase in the incidence and prevalence of IBD can be seen in this cohort. The prevalence of IBD was calculated to be 26.25/105 cases. The average number of IBD cases increased from 3 cases (average for the years 1984&ndash;2001) to 12 cases (average for the years 2002&ndash;2014). A number of factors correlate positively or negatively with CD and UC. In the current study, a link between gastrointestinal complications in CD cases and the use of steroids as a treatment was noted (p-value &minus;0.02). Age also had a significant influence on the need for surgery in CD cases (p-value &minus;0.04), and a family history of UC was statistically linked to surgical intervention (p-value &minus;0.05).Conclusions: IBD can no longer be considered a rare disease in Bahrain. The incidence of both UC and CD is steadily increasing. There is a need for increasing awareness of the Bahraini public to IBD in order for proper medical care to be given.
