    After Roux-en-Y gastric bypass (RYGBP), the excluded gastric remnant represents a challenge for the surgeon. Many diseases are reported to take place in that remnant, such as cancer, gastritis, and ulcer. On the other hand, diagnosing these pathological changes requires invasive intervention. We report the use of a noninvasive study to diagnose pathology in the bypassed stomach

    Should axillary artery to coronary artery bypass be part of the cardiac surgeon\u27s armamentarium?

    BACKGROUND: The axillary artery has been used as an alternate inflow source for revascularization of the lower extremities for four decades. Since 1997, there have been several reports of axillary artery to coronary artery bypass. METHODS: All cases of axillary artery to coronary artery bypass at our institution from 1997 through 2003 were reviewed. PubMed was queried for publications on this subject and all pertinent reports were reviewed. RESULTS: Thirty-eight patients underwent axillary artery to coronary artery bypass at our hospital. Most (34) of the operations were performed without cardiopulmonary bypass. Saphenous vein (37) or radial artery (1) grafts were placed to one or more coronary arteries from either the left (36) or right (2) axillary artery. Twenty patients underwent sternotomy, and 18 had either a left (16) or right (2) minimally invasive direct coronary artery bypass (MIDCAB) procedure performed. Most of the sternotomies were for primary myocardial revascularization and most of the MIDCABs were reoperations. There were three deaths-all from non-cardiac causes, one myocardial infarction, and one transient brachial plexus injury. Doppler ultrasound, angiographic, and clinical follow-up were limited, but graft patency has been demonstrated up to 9 years. CONCLUSION: Axillary artery to coronary artery bypass should be part of the armamentarium of surgeons who perform myocardial revascularization operations

    Background Acute Appendicitis (AA) is the most common abdominal surgical emergency. It requires proper management to decrease mortality and morbidity. Clinical scoring systems for diagnosing AA aimed to decrease the use of radiological scans and the rate of negative appendectomies (NA). We aim to assess the adult appendicitis score (AAS) in the diagnosis prediction of AA. Method A retrospective study with 1303 cases of AA is performed. We compared the correlation of AAS and Alvarado scores to postoperative histopathology. Specificity, sensitivity, Positive Predictive Value (PPV), and Negative Predictive Value (NPV) were assessed. ROC was used. Results AAS risk stratification was applied to the study population. Group I for a low probability, and groups II and III for an intermediate and high probability of AA. We found that 159 patients were matched in group I, 505, and 639 were in groups II and III of AAS, respectively. The correlation between Alvarado and AAS with HP was significant. AAS ≥ 16 presented sensitivity and specificity of 50 % and 75.47 %, respectively, with PPV of 97.96 % and NPV of 6.02 %, with an accuracy of 51.04 %. Regarding AAS ≥ 11, the sensitivity was 88.96 %, specificity was 39.62 %, PPV was 97.2 %, NPV was 13.21 %, and accuracy was 86.95 %. Conclusion AAS is relatively more accurate than Alvarado's score, especially in selecting a safe candidate for discharge from an emergency. In addition, AAS is found to decrease the need for radiological images and NA rate more than Alvarado.The publication of this article was funded by the Qatar National Library .Scopu

    Consensus recommendations on fasting during Ramadan for patients with kidney disease: review of available evidence and a call for action (RaK Initiative)

    No full text
    Abstract Ramadan fasting (RF) involves abstaining from food and drink during daylight hours; it is obligatory for all healthy Muslims from the age of puberty. Although sick individuals are exempt from fasting, many will fast anyway. This article explores the impact of RF on individuals with kidney diseases through a comprehensive review of existing literature and consensus recommendations. This study was conducted by a multidisciplinary panel of experts. The recommendations aim to provide a structured approach to assess and manage fasting during Ramadan for patients with kidney diseases, empowering both healthcare providers and patients to make informed decisions while considering their unique circumstances

    Determinants of COVID-19 Vaccine Acceptance among Dental Professionals: A Multi-Country Survey

    No full text
    Purpose: This study sought to investigate the acceptance rate and associated factors of COVID-19 vaccines among dentists and dental students in seven countries. Material and Methods: A structured questionnaire prepared and guided by the report of the SAGE Working Group on Vaccine Hesitancy was distributed among groups of dentists and dental students in seven countries across four continents. Results: A total of 1527 subjects (850 dentists and 677 dental students) participated in this survey. Although 72.5% of the respondents reported their intention to accept COVID-19 vaccines (dentists: 74.4%, dental students: 70.2%), there was a significant difference in agreement between dentists/dental students across countries; generally, respondents in upper-middle-, and high-income countries (UM-HICs) showed significantly higher acceptance rates compared to those in low- and lower-middle income countries (L-LMICs). Potential predictors of higher vaccine acceptance included being a dentist, being free of comorbidity, being well-informed about COVID-19 vaccines, having better knowledge about COVID-19 complications, having anxiety about COVID-19 infection, having no concerns about the side effects of the produced vaccines and being a resident of an UM-HIC. Conclusion: The results of our survey indicate a relatively good acceptance rate of COVID-19 among the surveyed dentists and dental students. However, dentists and dental students in L-LMICs showed significantly lower vaccine acceptance rates and trust in COVID-19 vaccines compared to their counterparts in UM-HICs. Our results provide important information to policymakers, highlighting the need for implementation of country-specific vaccine promotion strategies, with special focus on L-LMICs
