Merkel cell carcinoma (MCC) is a rare neuroendocrine cutaneous malignancy. During early stages, surgery is the primary treatment followed by radiotherapy in patients at high risk of recurrence. Definitive radiation therapy is an alternative for patients who are not surgical candidates, reserving chemotherapy for metastatic disease. We present a case of a male patient diagnosed with MCC and stage IV colorectal cancer and we focus on the skin tumor shrinkage after specific colorectal cancer treatment.Cardiac amyloid is an uncommon cause of diastolic dysfunction the recognition of which requires the internist to have clinical suspicion to guide diagnosis and treatment. Cardiac amyloid is an infiltrative cardiomyopathy with significant morbidity and mortality. Appropriate diagnosis is important because management of cardiac amyloid differs from typical heart failure with preserved ejection fraction. An astute internist must be able to recognize common findings of cardiac amyloidosis. Here we present a case of a patient presenting with diastolic heart failure and the steps leading towards diagnosis and subsequent treatment.Introduction Sepsis is a common medical condition that is associated with very high mortality and, in survivors, long-term morbidity. Conventional inflammatory markers, such as CRP, erythrocyte sedimentation rate (ESR), and white blood cell count (WBC), have proven to have a limited utility in sepsis patients by virtue of their poor sensitivity and specificity for infections. Recently, the commonly used index of red cell distribution width (RDW) has been implicated as a prognostic marker in sepsis. This study aimed at assessing the role of RDW in predicting outcomes such as mortality in patients with sepsis and to study its role as a prognostic marker. Methods This was conducted as a prospective comparative observational study over a two year period between 2018 and 2020 in a tertiary care center in South India. In total, 60 adult patients above 18 years of age who were diagnosed to have severe sepsis and septic shock were selected to be part of the study. To find the survival probability on overall survival,oup but was not significant (p=0.07). Conclusion We found that an increase in RDW from baseline during the initial 72 hours after admission is significantly associated with adverse clinical outcomes including mortality. The mortality in the rise in the RDW group, as well as overall mortality, were significantly higher than the mortality in the reduced RDW group. Hence, serial RDW measurements could be used as a prognostic factor in severe sepsis and septic shock.Objective The aim of this study was to determine the association of serum vitamin D and immunoglobulin E (IgE) levels with the severity of allergic rhinitis (AR). Methods This case-control study was conducted at Mayo Hospital, Lahore, from June to September 2020 after obtaining ethical approval. Patients of AR were included and divided with the help of allergic rhinitis and its impact on asthma (ARIA) classification, into group A (cases), patients presenting with moderate to severe symptoms, and into group B (control), patients with mild symptoms, after treatment of AR. The mean difference between serum IgE and serum Vitamin D levels of both groups were compared by t-test. Association was determined by logistic regression and odds ratio. Results A total of 224 patients were included in the study, 112 patients in group A and 112 patients in group B. There were 106 (47.3%) female and 118 (52.7%) male. The mean age of patients in group A was 26.78± 8.92 years and in group B, it was 25.72±8.12 years. Mean serum vitamin D levels in group A were 16.24±6.7 ng/ml and in group B 26.92±35 ng/ml (p=0.0001). Mean serum IgE levels in group A were 383.69±154.86 IU/ml and in group B, they were 373.03±106.83 IU/ml (p=0.0001). Vitamin D deficient patients were 24 times more likely to develop moderate to severe AR disease. Conclusion This study showed that in moderate-severe AR, IgE levels are raised statistically as compared to mild AR and the deficiency of Vitamin D is associated with increasing severity of allergic rhinitis symptoms.The neck is essential and vital for all head movements and performing daily functional activities. The second-degree deep dermal and full-thickness burns causing anterior neck contracture restricts movement and if untreated develop deformities, in the oral cavity, eyes, posture, and chin growth and development, especially in children. Neck contracture results in kyphoscoliosis, lower lip seal resulting in impaired vision, balance, swallowing, feeding, and speech as well as social stigma, depression, and embarrassment. The treatment for post-burn anterior neck contractures is contracture release and reconstruction with skin grafts (split and full-thickness), axial pattern flaps, perforator propeller flaps, microvascular free flaps, tissue expansion, prefabrications, and skin substitutes. In addition to functional and esthetic recovery, post-surgery social and vocational rehabilitation is essential for children. We report a ten-year-old boy with severe anterior neck post-burn contracture managed with unilateral supraclavicular flap and residual areas with a split-thickness skin graft.
In low-income and high hepatitis B and C virus burden countries like Pakistan, it is important to develop cheap yet efficient strategies in diagnosing as well as treating hepatitis. The aim of this study is to assess the sensitivity and specificity of serum hepatitis B surface antigen (HbsAg) via Rapid Immunoassay Chromatographic Test (RICT) for the screening of hepatitis B, compared to the gold standard laboratory-based method.
The study was conducted in the Hepatology Clinic of Civil Hospital, Sukkur. All records of the clinic from June 1, 2018, to December 31, 2018, were accessed for identification of the records in which hepatitis B screening via RICT and then confirmatory polymerase chair reaction (PCR) by gene amplification with forward and reverse primers was done.
There were 151 samples in this study. There were 32 (94.1%) true-positive and three (5.8%) false-negative samples. There were two (2.5%) false-positive and 114 (97.4%) true-negative samples. The sensitivity of HbsAg detection via RICT for the screening of 1-1B V was 91.43%, specificity was 98.28% and the accuracy was 96.69%, compared to PCR.
The RICT method has high sensitivity and specificity. In low-income and high-hepatitis B virus-burden countries like Pakistan, it serves as a very efficient screening tool that is easy to use, cheaper in cost, and gives rapid and accurate results.

The earliest symptoms of MELAS typically include easy fatigability, muscle weakness, encephalopathy with stroke-like episodes, recurrent headaches and seizures. The pathogenesis of stroke-like episodes manifesting as focal deficits like acute cortical blindness is not fully understood. We present an eight-year-old, right-handed boy with MELAS confirmed by the presence of pathogenic missense variant mutation (mt.3243A>G) presenting with acute intermittent reversible episodes of cortical blindness and Anton-Babinski Syndrome secondary to concurrent occipital lobe seizures captured during video electroencephalography (V-EEG) monitoring, in addition to the neuro-imaging which was not consistent with acute ischemic stroke. This case highlights the importance of the V-EEG monitoring besides clinical testing and radiographic correlation during acute cortical blindness episodes in MELAS as occipital lobe seizures could be a part of the symptomatology.Background The asymmetric medial and lateral condyles of the distal femur and proximal tibia have a direct influence on the biomechanics of knee joint and prostheses design. This study aimed to determine the morphologic data, that is., anteroposterior (AP) and mediolateral (ML) widths, and the radius of curvature (ROC) of the geometric arcs of the distal femur and proximal tibia. Methods One hundred and seventeen adult dry bones (57 femurs and 60 tibias) were studied. Aspect ratios (AP/ML) were calculated. The AP and ML widths were measured using digital Vernier Caliper with a measuring range of 0-150 mm, resolution of 0.01 mm, and accuracy ± 0.02 mm. The geometric arcs of femoral and tibial condyles were divided into three parts namely anterior 1/3rd, distal (femur) or middle (tibia) 1/3rd and posterior 1/3rd and were estimated in the sagittal plane for the femur and transverse plane for tibia using the ROC gauges. Results For the femur, the mean AP length for medial and lateral condyles was 55.62 mm and 57. 'anatomic' knee prostheses appropriate for the local population which would not only improve function but also prolong the longevity of the prostheses.Simulation's benefits in medical education are well established. However, its use for pandemic preparedness in obstetrics is lacking. Management of obstetrical patients with suspected COVID-19 infection is a complex task with safety considerations for mother, fetus and healthcare workers. Implementation of new workflow algorithms to ensure safety is critical but is challenging to implement in real-time. We sought to improve pandemic preparedness by designing and deploying a high-fidelity simulation exercise involving the admission of a labouring obstetrical patient with suspected COVID-19 into a labour room, urgent transfer to the operating room and neonatal resuscitation. The creation of the simulation scenario was a multi-disciplinary effort with input from a focus group of key clinical stakeholders from within and outside of our centre to ensure clinical validity. Simulations were performed on the clinical unit during regular work hours so workflow could be observed in real-time with access to the equipment and personnel in which this clinical scenario would occur. We completed a total of 11 simulation sessions involving 42 participants. Feedback, obtained from debrief sessions and anonymous surveys, was categorized based on the human factors framework, and used as part of an iterative process to adapt, revise and improve the simulation scenario. The result of this iterative process was the creation of validated departmental infection control protocols that continue to be implemented through the second wave of the COVID-19 pandemic.Acute mastoiditis in a newborn complicated by the presence of facial nerve palsy is an alarming finding requiring rapid assessment and further investigation. Such an early presentation should point the clinician towards an underlying systemic pathology or congenital anatomical abnormality. Facial nerve involvement indicates severe infection and possible dehiscence of the facial canal. Although more frequent in children, it is rare in neonates. We would like to share our experience in managing the youngest known presentation of otomastoiditis at four days of life. The patient presented with otorrhea and facial paralysis and progressed to meningitis. He was finally diagnosed with chronic granulomatous disease.
