Prevalence of Peripheral Arterial Disease in Diabetic Foot Ulcer Patients and its Impact in Limb Salvage.

Diabetic foot ulcer syndrome is a common complication of diabetes mellitus. Three main factors contribute to it: neuropathy, vasculopathy, and infection. This study was conducted to evaluate the prevalence of peripheral arterial disease (PAD) in diabetic foot ulcer patients and its impact on limb salvage as an outcome. This prospective cross-sectional study included 392 cases, who were divided according to the presence of PAD into 2 groups; patients with PAD were labeled as PAD +ve (172 cases) and those without PAD were labeled as PAD -ve (22 cases). All cases were clinically assessed, and routine laboratory examinations were ordered. Moreover, duplex ultrasound was done for suspected cases of having PAD by examination. Computed tomography angiography was ordered for patients who are in need of a revascularization procedure. Cases were managed by debridement and/or revascularization. After that, these cases were assessed clinically and radiologically for vascularity and infection and the possibility for amputation was evaluated. Infection was classified using Wagner Classification System, and revascularization was decided according to the TASC II system. The incidence of PAD in cases with diabetic foot ulcer syndrome was 43.87%. No difference was detected between the 2 groups regarding age and gender (P > .05). The prevalence of smoking, hemodialysis, ischemic heart disease (IHD), and hypertension was more significantly higher in cases with PAD (P < .05). Revascularization procedures were only performed in cases that had documented severe PAD or chronic limb-threatening ischemia in addition to foot ulcer and/or infection. With regard to limb salvage, it was more significantly performed in cases without PAD (82.3% vs 48.3% in PAD cases; P < .001). Male gender, smoking, ankle-brachial pressure index, hemodialysis, IHD, neuropathy, HbA1C, PAD, and high Wagner classification were predictors of limb amputation (P < .05). PAD is associated with worse outcomes in diabetic foot ulcer patients. Not only does it constitute a great number among diabetic foot ulcer patients, but it also has a negative impact on limb salvage.

Cardiac Catheterization During Extracorporeal Membrane Oxygenation After Congenital Cardiac Surgery: A Multi-Center Retrospective Study.

Cardiac catheterization can affect clinical outcomes in patients on extracorporeal membrane oxygenation (ECMO) after congenital heart surgery; however, its effect in this group of patients remains unclear. This study aimed to evaluate the safety and outcome of cardiac catheterization in patients undergoing ECMO after congenital cardiac surgery and determine predictors that influence successful weaning. This retrospective cohort study included pediatric patients who underwent cardiac catheterization while on ECMO after congenital heart surgery in two cardiac centers between November 2012 and February 2020. Predictors of successful weaning from ECMO were studied using univariate and multivariate logistic regression analyses. Of 123 patients on ECMO support after congenital cardiac surgery, 60 patients underwent 60 cardiac catheterizations (31 diagnostic and 29 interventional). Thirty-four (56.7%) and 22 patients (36.7%) underwent successful decannulation from ECMO support and survived after hospital discharge, respectively. Patients who underwent earlier catheterization (within 24 h of ECMO initiation) had more successful weaning from ECMO and survival compared to others. Patients who underwent an interventional procedure (interventional catheterization or redo cardiac surgery after cardiac catheterization) had better survival than those who underwent only diagnostic catheterization (P = 0.038). Shorter durations of ECMO was the most important predictor of successful weaning from ECMO. Early cardiac catheterization greatly impacts successful weaning from ECMO and survival. Patients with correctable lesions amenable either by catheterization or redo surgery are more likely to survive. Shorter durations of ECMO could have a significant influence on successful weaning from ECMO and survival.

Chorea-acanthocytosis: A Case Report with Review of Oral Manifestations.

Chorea-acanthocytosis (ChAc) is an autosomal recessive, progressive neurological disorder due to mutation in VPS13A gene causing defects in sorting of protein making the cell membrane unstable, leading to star-shaped erythrocytes. This neurological disorder includes features such as elevated creatinine kinase, atrophy of basal ganglia, and oral manifestations such as frequent cheek and tongue biting. It is a rare neurological condition with an estimate of <1000 cases worldwide. A case of 47-year-old male patient with a history of seizures and neurological problems presenting with oral ulceration has been discussed. The diagnosis of ChAc was confirmed by molecular investigations showing VPS13A gene mutation. The physical appearance includes chorea and dystonia with impaired gait. We attempt to highlight the oral features of ChAc. The oral manifestations include frequent tongue and cheek biting occurring due to dystonia affecting the muscles of head and neck region.

Burnout and its associated factors among medical students of Jazan University, Jazan, Saudi Arabia.

PURPOSE: The purpose of this study is to assess the prevalence of burnout syndrome and its associated factors among medical students at Jazan University, Jazan, Kingdom of Saudi Arabia. DESIGN/METHODOLOGY/APPROACH: A cross-sectional survey was conducted among 440 randomly selected medical students at Jazan University. The questionnaire used for this study was based on the Copenhagen Burnout Inventory. FINDINGS: The overall prevalence of burnout was estimated at 60.2% (95% CI 55.6-64.8). The prevalence was higher for females (64.1%) than for males (56.2%) but without statistically significant differences (p > 0.05). On average, the students scored the highest averages in the personal burnout category, followed by the study-related and client-related burnout categories. In the multivariate analysis, a lower age (beta = -3.17, p = 0.026), female (beta = -0.896, p = 0.016), and having better burnout knowledge (beta = 0.710, p = 0.025) predict significantly higher personal burnout. PRACTICAL IMPLICATIONS: It is necessary to implement strategies to reduce the incidence of burnout among medical students for the sake of a better quality of life for future doctors. ORIGINALITY/VALUE: There is a high prevalence of burnout among Jazan's medical students.

Role of iron deficiency anemia in the propagation of beta thalssemia gene

BACKGROUND: The diagnostic criterion for beta thalassemia trait (BTT) is elevated Hb-A2 levels. Iron deficiency anemia (IDA) reduces the synthesis of Hb-A2, resulting in reduced Hb-A2 levels, so patients with co-pathological conditions BTT with IDA, may have a normal level of Hb-A2. Many socio-economic factors like unawareness, poor diagnostic facilities, and cost of molecular diagnosis (for screening purposes) result in interpretation of these subjects as normal. METHODS: Venous blood samples from 200 unmarried females having a family history of thalassemia were collected, and basic hematological parameters, hemoglobin electrophoresis, and molecular analysis for beta thalassemia were done. Patients with IDA and patients with co-pathological conditions BTT and IDA were treated with oral iron. These subjects were then followed for a period of 20 weeks. RESULTS: Of the 200 females, 34 were found to be anemic. Hemoglobin electrophoresis identified 16 of these patients as BTT. Molecular analysis of all patients confirmed this diagnosis, but identified 8 additional patients with BTT. Eight patients that were not detected with hemoglobin electrophoresis were found to have co-pathology of BTT with IDA. CONCLUSION: Patients with the co-pathological condition BTT with IDA may be interpreted as being normal, as they have normal Hb-A2 levels. These misdiagnosed subjects when marry with BTT have the potential to produce beta thalassemia major in offspring. This is one of the factors playing a major role in the propagation of beta thalassemia gene in Pakistani population, and become a serious hindrance for the thalassemia prevention program in Pakistan.
