Spontaneous Lung Herniation Leading to Extensive Subcutaneous Emphysema, Pneumothorax, Pneumomediastinum, and Pneumopericardium.
Spontaneous lung herniation is a rare phenomenon in which the lung parenchyma along with the pleural membranes protrudes outside their usual boundaries and can lead to a wide variety of complications. We are reporting a case of a middle-aged male who presented with chronic obstructive pulmonary disease (COPD) exacerbation with severe bouts of cough. Initial computed tomography (CT) chest was unrevealing, but two days later, he developed spontaneous lung herniation, which was initially managed conservatively, but later it progressed to pneumothorax, pneumomediastinum, with striking CT scan images showing extensive subcutaneous emphysema. Blowhole incisions were done on the anterior chest wall which led to ultimate recovery
Assessment of diastolic function in patients with aortic valve diseases
Background: Valvular heart disease (VHD) are prevalent and impose significant impact on heart function. Diastolic Dysfunction (DD) is less appreciated than Systolic Dysfunction (SD). The aim of this study was to assess the Diastolic Function (DF) in patients with Aortic Valve (AV) diseases as risk factors predisposing to DD.Methods: Cross-section study that involved 34 patients with AV diseases and other 10 controls. All patients are assessed for diastolic dysfunction by transthoracic echo Doppler study. M-mode echocardiography was used to measure cardiac dimensions and wall thickness. LV mass was measured on echocardiogram at rest.Results: Among the 34-patients, 19 (55.8%) of them were male patients and 15(44.2%) of them were female patients. The data showed that there were 12 patients with Aortic Stenosis (AS), eight patients with AORTIC regurgitation (AR), six patients with Aortic Sclerosis (ASCL) and 8 patients with combined AR-AS. Around third of the patients (35.3%) had Grade II DD followed by grade I and Grade III. However, around 14.7 % didn’t have any dysfunction. Overall, there was 77% of the patients with AV diseases.Conclusions: Author concluded that Aortic Valve diseases is significantly related to- the development of diastolic dysfunction and the DD is influenced by severity of AV diseases
Another D in MUDPILES? A Review of Diet-Associated Nondiabetic Ketoacidosis.
Ketogenic diet or very-low-carbohydrate diet gained widespread popularity in the 1990s due to their favorable effects on weight loss and diabetes among others with good short-term safety data. People on ketogenic diets exist in a state of dietary ketosis in which the body production of ketone is equal to consumption and no harmful effects of ketonemia occur. However, in face of stress, the harmless dietary ketosis can lead to profound acid-base disturbances due to massive overproduction of ketone bodies that overwhelms the acid buffer system of the body. A handful of case reports have been published on this topic calling the safety of ketogenic diet into question. In this article, we chronicle a unique case of ketogenic (Atkins) diet-associated ketoacidosis, and we present a comprehensive literature review on the etiology of ketoacidosis
Association of hypoadiponectemia with smokeless/dipping tobacco use in young men
Background: Low levels of adiponectin, an adipocytokine with anti-diabetic, antiatherogenic and cardioprotective
properties, is associated with increased risk of coronary disease in young men. Previous studies have demonstrated
that smokeless tobacco is linked with a reduction of plasma adiponectin levels. However, the influence of
smokeless tobacco (dipping tobacco) on plasma adiponectin levels still remains unknown. This study was
conducted to assess the plasma adiponectin levels in young men who were using dipping tobacco.
Methods: This was a community based study, which consisted of 186 young lean healthy males aged 20 to
35 years. Among these, 96 men were dipping tobacco users (BMI = 23.07 ± 2.68) and 90 were non-dipping
tobacco users (BMI = 23.67 ± 1.46). Serum adiponectin levels were assessed by Enzyme Linked ImmunoSorbent
Assay (ELISA).
Results: A statistically significant difference in the mean adiponectin level between tobacco dipper and non-dipper
groups was observed (p = 0.0001). A significant difference between the two groups was also observed in
baseline parameters including triglyceride and random blood sugar levels (p < 0.05). However, no significant
difference was observed between the two groups in other clinical parameters.
Conclusions: Findings of this study suggest that dipping tobacco use was significantly associated with low
level of adiponetin in community dwelling young males. This emphasizes the importance of developing
community intervention to reduce the use of dipping tobacco, which will reduce the tobacco associated
disease burden in the community and will improve public health
Posterior reversible encephalopathy syndrome (PRES) after bevacizumab therapy for metastatic colorectal cancer.
Posterior reversible encephalopathy syndrome (PRES) is an increasingly recognizable neuro-clinical syndrome. Clinical and neurological manifestations of PRES include hypertension, headache, encephalopathy, seizures, and symmetrical white matter changes on brain MRI. Most common precipitants of PRES are acute medical illness, hypertensive crisis, eclampsia, immunosuppressive therapy, and chemotherapy. Bevacizumab is a monoclonal antibody that halts angiogenesis by inhibiting vascular endothelial growth factor. It has gained widespread popularity in oncology world especially for metastatic and recurrent cancers due to its inherent ability to stop angiogenesis; a vital step for tumor growth. Bevacizumab has also been implicated as the cause of PRES due to dysregulation of the blood-brain barrier. We are reporting a case of PRES induced by Bevacizumab in a patient of colorectal cancer
Impact of sedimentalogical processes on mangrove ecosystem of the Indus Delta
A detailed sedimentalogical study concerning the depletion of mangrove in the Indus Delta due to the marked decrease in the supply of silt was undertaken. Thirty one stations were established for sampling in a selected area of 12000 hectares between Korangi creek and Wad do Khuddi creek. Seventy one samples of soil were collected from 6cm and 1m depth, out of which fifty one samples were selected for sedimentalogical studies. It was inferred from this study that the marine depositional processes are distinctly dominating over the fluvial processes, which is major cause in decreasing the growth of mangrove. It was also inferred that among the sampled stations the sites having clayey silt (with silt 60%-70% and clay 25%-30%) are most favourable for mangrove plantation
Electrocardiogram changes in patients with end stage renal disease on chronic haemodialysis
Background: End stage renal disease (ESRD) is irreversible loss of renal function which is physiologically defined by a GFR of less than 15 ml / minute. ESRD is associated with a higher incidence of coronary artery disease and serious arrhythmia especially ventricular arrhythmia. The goal of study is to determine whether ESRD and haemodialysis (HD)are associated with occurrence of significant electrocardiogram (ECG) changes or not.Methods: This is a cross-sectional study design which involved 22 patients with ESRD on regular HD in Al Sadre teaching hospital / Al Najaf. Both sexes was included in this study. All patients underwent full medical history and examination which included the following aspects: Age, Sex, Occupation, BP, HR, RBS, B.urea, S.creatinine , Serum electrolyte (Na+, K+, Cl-, Ca++), Lipid profile (Cholesterol , Triglyceride, HDL, LDL), Duration of CRF, Duration of dialysis, Social history including (smoking, alcohol) and Drug used by the patient. Resting EGC and Hotler ECG.Results: Eighteen patients exhibited emergence of simple ectopic activity premature atrial complex (PAC) and premature ventricular complex (PVC) events and four patients exhibited (ST,T changes). Potentially lethal arrhythmias and other serious ECG changes are not detected in our patient’s sample.Conclusion: In this study, neither ESRD nor haemodialysis were associated with development of serious ECG changes or emergence of significant arrhythmia
THE E-TOURISM BEYOND COVID-19: A CALL FOR TECHNOLOGICAL TRANSFORMATION
The upsurge of Covid-19 changed lifestyles and hit almost every sector. The tourism sector is one of the most affected sectors due to social distancing, ban on crowding, restrictions to visit public places, and grounded airplanes. The study proposed a shift to e-tourism until the Covid-19 get fully curbed. Therefore, this study aims to focus on the tourist’s experiences in Thailand during the Covid-19 pandemic. The study provides insight with the support of literature to help practitioners and researchers to understand, manage, and improve the tourism industry and induce technological transformation to curb the impact of the outbreak. The paper proposes a way to turn Covid-19 into a transformational opportunity. The study used Smart PLS software for analysis and data was collected from the tourist who had intentions to visit Thailand and the ones already in Thailand. The study fills the gap of the call for a transformation of e-tourism and explains the impact of the pandemic on the industry. The study presents the theoretical and practical implications to promote the tourism industry and the transformation of the technology in the Covid-19 pandemic
Contegra valved conduit in the paediatric population: an exciting prospect for right ventricle to pulmonary artery reconstruction; experience and outcomes at Aga Khan University
Objective: The focus of this study is to share the experience and outcomes of Contegra graft implantation in the paediatric and adult population in Pakistan. Methods: Between May 2007 and July 2011, 16 patients, underwent implantation of a Contegra valved conduit. All operations were performed through a median sternotomy with cardiopulmonary bypass. Indications included: Pulmonary atresia with ventricular septal defect (n=11), Tetralogy of Fallot with absent Pulmonary Valve (PV) syndrome (n=2), double outlet right ventricle, transposition of great arteries and pulmonary stenosis (n=1), isolated aortic valve disease (n=1) and a pseudo-aneurysm with infective endocarditis (n=1).Conduit sizes varied between 16-22 mm. Results: The three in hospital deaths were unrelated to the Contegra valved conduit. One patient was lost to follow up. Of the 12 survivors, 10 are currently free from re-operation or complications related to the conduit while one needed distal pulmonary artery dilatation owing to critical stenosis and another had severe Valvular regurgitation. Echocardiographic evaluation of the Contegra valved conduit demonstrated no haemodynamically significant valve regurgitation in 10 patients. Conclusion: In this small review of 16 operations using the Contegra valved conduit for Right Venticular Outflow Tract (RVOT) reconstruction in the paediatric population, we observed good post operative results concerning conduit function. The Contegra conduit provides an excellent substitute to the homograft with satisfactory early and mid-term results though long term results are awaited in Pakista
Novel Interaction Between ECD and EIF4A1 Indicates ECD Regulates Eukaryotic Translation
ECD, Ecdysoneless protein, is evolutionarily conserved. It was identified as a human homologue of Drosophila ecdysoneless, interacting with HPV16 E6 in a yeast two-hybrid assay. ECD has been proven to be essential for cell cycle progression from G1 to S phase, mitigating endoplasmic reticulum (ER) stress, and embryogenesis. ECD KO mice are embryonic lethal as it halts the cell cycle at G1. ECD interacts with p53 and Rb. ECD also associates with pre-mRNA splicing factor PRPF8. ECD is over-expressed in breast, pancreatic, gastric, and Human Papilloma-driven cancers and is correlated with shorter patient survival. ECD interacts with co-chaperone complex R2TP involved in protein assembly and folding. ECD over-expression has been proven to increase oncogenesis regulated by c-MYC in a recent mice model. Biochemical analyses showed ECD to have a role in mRNA splicing and nucleus to cytoplasm export. The purpose was to determine if there is an interaction between ECD and EIF4A1 and determine ECD’s effect on global translation using HEK293T (human embryonic kidney) and SUM159 (breast cancer) cell lines. Overall, the interaction between ECD and EIF4A1 supports a novel mechanism by which ECD protein regulates eukaryotic mRNA translation. This mechanism may contribute to the resistance of cancer cells over-expressing ECD to the translation-inhibitory effect of endoplasmic reticulum stress prevalent in tumors.https://digitalcommons.unmc.edu/surp2022/1031/thumbnail.jp
