Clec4e-Receptor Signaling in Myocardial Restoration After Ischemia-Reperfusion Harm.
Autoimmune hemolytic anaemia (AIHA) is a heterogenous disorder characterised by the presence of IgG or IgM pathological autoantibodies that target antigens of erythrocytes resulting in active hemolysis. Case presentation A 40-year-old gentleman presented to a medical centre with chest pain and right sided hemiparesis for a week. He was pale and jaundiced. The power of the right upper and lower limbs was 3/5. His spleen was palpable. His complete blood count revealed macrocytic anaemia of 7.6 g/dL. The brain Magnetic Resonance Imaging (MRI) showed left fronto-parietal infarction. The right cardiac and left carotid angiogram revealed thromboses involving the right coronary and left internal carotid artery respectively. At the cardiology department, he was transfused with two units of red blood cells without his anemia being investigated and a stent was deployed to the left internal carotid artery. He was referred to the hematology department in which his peripheral blood smear revealed hemolysis and his direct antiglobulin test was positive. He responded to a course of steroids and direct oral anticoagulation and is in complete remission for the past 18 months. Conclusion It is always imperative to investigate the cause of anaemia and consider hemolysis in a patient presenting with multiple unexplained thromboses.
Vitamin B12 (VitB12) deficiency rarely manifests with visual symptoms. Optic nerve damage in VitB12 deficiency is thought to be via degeneration. However, optic neuritis, though infrequent, has been reported secondary to VitB12 deficiency.

We conducted a systematic review of all the reported cases of VitB12 deficiency with optic nerve involvement in Pubmed, Cochrane, and Google Scholar any date up to September 6, 2020. We have discussed the findings and compiled the available information on ophthalmological manifestations of VitB12 deficiency. We aim to provide a unified knowledge about the evidence related to types of optic neuropathies reported to date secondary to VitB12 deficiency. We also present a case of bilateral optic neuritis secondary to VitB12 deficiency.

We present a 29-year-old previously healthy male with progressive, painful, bilateral, but asymmetric visual deterioration for forty-five days. A detailed history, examination, and laboratory workup were carried out. He was diagnosed as having optic neuritis secondary to VitB12 deficiency. He showed partial improvement with the replacement of VitB12.

We suggest promptly identifying and replacing VitB12 in patients with optic neuritis with proven VitB12 deficiency to prevent permanent damage to the optic nerve. Patients with VitB12 deficiency should have a baseline fundoscopic exam to rule out subclinical optic nerve damage. Moreover, patients who present with visual disturbances should be screened for VitB12 deficiency, especially the vegan population.

Moreover, patients who present with visual disturbances should be screened for VitB12 deficiency, especially the vegan population.•These two cases highlight the limitations in current grading systems, particularly in the context of gallbladder size.•We propose modifications to the PGS to include not only abnormal anatomy but instances of distorted gallbladder anatomy due to inflammation and/or the large to giant size in order to account for the increased risk of complications.•Both distorted gallbladder anatomy and giant gallbladder size can make laparoscopic cholecystectomy a challenge, and thus warrant contribution to overall clinical grade.•While the PGS, Tokyo Guidelines, and AAST grading scales are validated grading scales for acute cholecystitis, additional modifications can further characterize different types of acute cholecystitis to better guide patient management.
Stroke data from Sierra Leone is limited, despite the increase in global burden of the disease. The aim of this study was to assess the risk factors, clinical outcomes and predictors of stroke mortality at a tertiary hospital in Freetown, Sierra Leone.

This retrospective cohort study was conducted on stroke patients admitted at the Connaught Teaching Hospital between 1st January to December 31, 2018. Clinical data related to stroke, with variables including patients' demographics, stroke subtype, vascular risk factors, modified Rankin Scale (mRS), and outcomes were documented. In-hospital mortality, associated risk factors and predictors of stroke were determined. The study was approved by the Sierra Leone Ethics and Scientific Review Committee. It was registered under Research Registry https//www.researchregistry.com/browse-the-registry#home/with the unique identifying number researchregistry6009.

We studied 178 (95 male and 83 female) patients. The mean age was 59.8±14.0 years, median was 58.1years (rhighlights a high stroke mortality in a resource limited hospital, with some stroke patients having difficulties in accessing Computer Tomogram (CT) scan services. It illustrates the need to establish a stroke care setting to improve the quality of stroke care.
The clinical impacts of bilateralism on prognosis and clinical decision-making remain contradictory particularly in areas with low incidence and delayed diagnosis of primary breast cancer. Identification of women at risk of bilateral breast cancer is required to improve patient management and to design the appropriate surveillance.

A total of 1083 women were enrolled and analyzed for the presence of synchronous and metachronous bilateral breast cancer as cases and unilateral breast cancer as controls during the median follow-up of 4.8 years.

The incidence of bilateral breast cancer was 7.5% (81 of 1083). In comparison with unilateral breast cancers, bilateral cases were significantly diagnosed in younger women (
=0.037, mean age was 35.6 years) who had a larger tumor size (
=0.012, mean tumor size was 8cm in diameter). Histological type of lobular cancer was identified as one of the risk factors for the development of contralateral breast cancer (OR 5.564, 95% CI 3.219-9.620) and synchronous bilateral breast cancer (OR 2.
