Deranged Liver Function Test After COVID 19 Vaccination: A Rare Presentation With Review Of Literature.

Word Health Organization declared COVID 19 infection as pandemic in 2020. Since then different countries had started working on vaccination. After multiple trials different vaccinations got approved. The first vaccine to be received in Pakistan was Sinopharm and was provided to nearly all health care professionals on priority basis. The safety profile of different vaccines were satisfactory and there were very few side effects reported till date. We are reporting the first case in Pakistan where a female health care professional developed vaccination induced deranged liver function test with delayed but complete recovery. Extensive workup was done to rule out all other differentials of deranged liver function test.

Does drinking water with raised fluoride content affect the thyroid hormone status: A study from Tharparker Pakistan.

OBJECTIVE: To determine the effect of consuming water with high fluoride content on thyroid hormone status. Methods: The comparative cross-sectional study was conducted at Sammu Rind village of district Tharparkar, Pakistan, where ground water was the only source of drinking and had fluoride content >6-8mg/dL, and another set of people from Gadap Town, Karachi, where ground water had fluoride level of 0.3mg/L. Thyroid profile, including serum thyroid stimulating hormone, free triiodothyronine and free thyroxine, were checked for both the exposed and the unexposed groups, and data was cross-tabulated with thyroid profile to check statistical significance. Data was analysed using SPSS 20. RESULTS: Of the 242 subjects, 121(50%) each were in the exposed and the unexposed group. Among the exposed, 15(12.4%) people had hypothyroidism, 104(86%) had euthyroid and 2(1.6%) had hyperthyroid. Corresponding values in the unexposed group were 10(8%), 105(87%) and 6(5%). The difference was not statistically significant (p>0.05).

An infrequent case of adult nasopharynx rhabdomyosarcoma with bony involvement: A case report.

Rhabdomyosarcoma is a rare and highly aggressive malignancy arising from the striated skeletal muscle fibre. It is commonly a childhood tumour and rarely seen in adults. The most predominant part commonly involved is head and neck. We are reporting a rare case of a 54 year old adult male with Rhabdomyosarcoma of nasopharynx with a non specific presentation of weight loss for past four months, fever, a perianal abscess and backache since 10 days. The haematological and biochemical parameters were within normal limits however C reactive protein and erythrocyte sedimentation rate were raised. An MRI for the pelvis, which was done for the extension of perianal abscess, also displayed some heterogeneous marrow signal, which raised the suspicion of some infiltrative process. Later, a bone scan, PET scan, and a biopsy of the nasopharaynx was done. The biopsy confirmed the findings of Rhabdomyosarcoma by showing marked pleomorphism with strong positive desmin and myogin stain. The patient was then referred to the oncology department for further management.

Possible protective mechanisms exerted by metformin or metformin and vitamin E in isoproterenol-induced cardiac injury.

Several studies have reported that metformin is cardioprotective for diabetic and non-diabetic ischemic hearts through mechanisms that cannot be entirely attributed to its anti-hyperglycemic effect. This study was designed to investigate the cardioprotective effects of metformin with and without vitamin E after induction myocardial infarction (MI) in rats, using isoproterenol. Administration of metformin or vitamin E significantly reduced the cardiac mass index (P < 0.01), ameliorated the changes to cardiac biomarkers, and attenuated oxidative stress levels compared to the isoproterenol group. Interestingly, combination therapy showed a slight synergistic effect. Histopathological analysis suggested that metformin treatment reduced NF-κB expression and protected against isoproterenol-induced MI. Our results indicate that metformin mediates a cardioprotective effect against isoproterenol-induced MI via antioxidant activity and modulation of the NF-κB signaling pathway. This suggests that metformin would be beneficial in MI treatment.

Clinical reappraisal of the composite international diagnostic interview version 3.3 in Qatar's National Mental Health Study.

OBJECTIVES: Lifetime DSM-5 diagnoses generated by the lay-administered Composite International Diagnostic Interview for DSM-5 (CIDI) in the World Mental Health Qatar (WMHQ) study were compared to diagnoses based on blinded clinician-administered reappraisal interviews. METHODS: Telephone follow-up interviews used the non-patient edition of the Structured Clinician Interview for DSM-5 (SCID) oversampling respondents who screened positive for five diagnoses in the CIDI: major depressive episode, mania/hypomania, panic disorder, generalized anxiety disorder, and obsessive-compulsive disorder. Concordance was also examined for a diagnoses of post-traumatic stress disorder based on a short-form versus full version of the PTSD Checklist for DSM-5 (PCL-5). RESULTS: Initial CIDI prevalence estimates differed significantly from the SCID for most diagnoses ( χ 1 2 ${\chi }_{1}^{2}$  = 6.6-31.4, p = 0.010 < 0.001), but recalibration reduced most of these differences and led to consistent increases in individual-level concordance (AU-ROC) from 0.53-0.76 to 0.67-0.81. Recalibration of the short-form PCL-5 removed an initially significant difference in PTSD prevalence with the full PCL-5 (from χ 1 2 ${\chi }_{1}^{2}$  = 610.5, p < 0.001 to χ 1 2 ${\chi }_{1}^{2}$  = 2.5, p = 0.110) while also increasing AU-ROC from 0.76 to 0.81. CONCLUSIONS: Recalibration resulted in valid diagnoses of common mental disorders in the Qatar National Mental Health Survey, but with inflated prevalence estimates for some disorders that need to be considered when interpreting results.

Design and field procedures for the clinical reappraisal of the Composite International Diagnostic Interview version 3.3 in Qatar's national mental health study.

BACKGROUND: The Composite International Diagnostic Interview (CIDI) has been clinically reappraised in several studies conducted mainly in the US and Europe. This report describes the methodology used to conduct one of the Middle East's largest clinical reappraisal studies. The study was carried out in conjunction with the World Mental Health Qatar-the first national psychiatric epidemiological study of common mental disorders in the country. This study aimed to evaluate the diagnostic consistency of core modules of the newly translated and adapted Arabic version of the CIDI 5.0 against the independent clinical diagnoses based on the Structured Clinical Interview for DSM-5 (SCID-5). METHODS: Telephone follow-up interviews were administered by trained clinicians using the latest research edition of the SCID for DSM-5. Telephone administered interviews were key in the data collection, as the study took place during the COVID-19 pandemic. RESULTS: Overall, within 12 months, 485 interviews were completed. The response rate was 52%. Quality control monitoring documented excellent adherence of clinical interviews to the rating protocol. CONCLUSIONS: The overall methods used in this study proved to be efficient and effective. For future research, instrument cultural adaptation within the cultural context is highly recommended.

Dandy-Walker malformation and intermittent explosive disorder: A case report.

Dandy-Walker malformation is a group of brain malformations that sometimes present with psychotic features, violent and impulsive behavior, or mood symptoms. Here, we present a case report of a patient with Dandy-Walker malformation who presented with intermittent explosive disorder. A young man, aged 18 years, was brought to the author's hospital [Hamad Medical Corporation] with anger outbursts, irritable mood, and violent behavior. His magnetic resonance imaging scans showed typical alterations of Dandy-Walker malformation. He also had mild intellectual disabilities and epilepsy. After a few weeks of treatment with sodium valproate 1000 mg/day and risperidone 2 mg/day, his condition improved, and his violent behavior was significantly reduced in 3 months, 6 months, and 1 year of follow-up. There is broad consensus that Dandy-Walker malformation is associated with psychosis and other behavioral abnormalities because of a possible disruption in the prefrontal, thalamic, and cerebellar circuits. The link between Dandy-Walker malformation and intermittent explosive disorder may help us understand this type of brain malformation as a potential psychiatric comorbidity.

Barriers and adherence to glaucoma medication in a paediatric glaucoma population: A cross-sectional survey in central Saudi Arabia.

PURPOSE: To examine barriers and adherence to topical glaucoma medication in a pediatric glaucoma population in Saudi Arabia. METHODS: This cross-sectional study was undertaken at the King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia during 2016-2017. Parents (father or mother) of children aged 6 months to 15 years with a history of glaucoma were interviewed. Rasch analysis was performed to assess the psychometric properties of the developed 12-item barriers-to-adherence tool (BAT-12) and to identify barriers deemed highly important. The 12-items were adapted from previous studies examining different barriers to adherence in different populations. Medication adherence was assessed by asking parents a series of closed-ended questions about the frequency of missed medications. Determinants of missed medications on at least 1 out of the last 3 days were examined using Poisson regression. RESULTS: One hundred and six parents were interviewed. The 12-item scale had acceptable psychometric properties. Barriers deemed important were forgetfulness (logit -0.59), complex dosing regimen (logit 0.09), and being too busy with other work/activities (logit 0.14). When asked how often, on average, their child missed the prescribed medication, 26 (24.5%) reported daily, 17(16.0%) reported few times per week, and 32 (30.2%) reported once per week. A third of parents (n = 37, 34.9%) reported having missed giving all drops on at least one day in the last 3 days. Poisson regression with robust variance revealed that increase in age of the child (prevalence ratio, 1.08 [95% CI, 1.03-1.14]; p = 0.003) and increase in parents' barriers score (prevalence ratio, 2.13 [95% CI, 1.49, 3.03]; p < 0.001) were significantly associated with having missed medications on at least one out of the last three days while adjusting for the effect of father's current employment status and area of residence. CONCLUSIONS: The tool we used to examine barriers to glaucoma medication had acceptable psychometric properties and could be used and strengthened in future studies. Our study highlights poor adherence to glaucoma medications among children with glaucoma.

Effect of drinking high fluoride water on liver enzymes a comparitive cross-sectional study.

Objective: The aim of this study is to determine the effects of drinking water with high fluoride level on liver functions. Method: This is a descriptive comparative cross-sectional study conducted at Sammu rind village where the drinking water has increase fluoride content. The comparative area was Gadap town where the drinking water has normal fluoride level. Sampling was done randomly and sample size was calculated by WHO calculator and found to be 121 each for exposed and unexposed population. Blood samples taken for liver functions included bilirubin, AST, ALT, Alkaline phosphate, Gamma GT, total protein, albumin and globulin. SPSS version 16 was used for analysis. Mean and SD calculated for quantitative variable and the two comparative groups were cross-tabulated. To check the statistical significance t-test was applied. Results: There was no statistically significant difference with consideration to serum bilirubin, ALT, and AST. However, statistically significant difference was established with respect to alkaline phosphatase, Gamma GT total proteins and A/G ratio between two groups. Conclusion: In our study, there was no evidence of impaired liver function tests in subjects drinking water with high fluoride content.

Frequency of Comorbidities in Admitting COVID-19 Pneumonia Patients in a Tertiary Care Setup: An Observational Study.

Background The novel coronavirus disease 2019 (COVID-19) is a highly infectious and pandemic disease with a variable mode of action. Patients with underlying illnesses such as diabetes, hypertension, and other diseases are more prone to infection. An understanding of the different comorbidities that place patients at the highest risk of COVID-19 pneumonia and other fatal complications associated with COVID-19 is necessary for healthcare professionals. This study aimed to determine the frequency of different comorbid illnesses among COVID-19 patients admitted to a tertiary care hospital in Karachi, Pakistan. Methodology All patients diagnosed with COVID-19 who required admission for the care of their symptoms were included in this observational, cross-sectional study conducted from May 1 to July 30, 2020. The patients were treated at a specialized COVID-19 isolation ward built at the Dow University of Health Sciences at the Ojha campus. The patients were referred from the emergency department, medical and allied wards, and COVID-19 screening units. A detailed history and clinical examination were performed, and comorbidities were evaluated. Results A total of 212 patients were admitted during the study with a mean age of 52 ± 16 years. The study population consisted of 120 (56.6%) males and 92 (43.39%) females, and the most common comorbidities were uncontrolled diabetes with hypertension (n = 56; 26.4%), controlled diabetes (n = 22; 10.37%), obstructive airway disease (n = 16; 7.5%), and interstitial lung disease (n = 14; 6.6%). A total of 48 (22.64%) patients had no comorbidities. Conclusions Most COVID-19-positive patients with pneumonia were male, and common comorbidities included uncontrolled diabetes, hypertension, and obstructive and restrictive lung disease. The presence of comorbidities was associated with a marked increase in the risk of morbidity and mortality. Further studies are warranted to confirm these findings.

SARS-CoV-2 and immune-microbiome interactions: Lessons from respiratory viral infections.

By the beginning of 2020, infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had rapidly evolved into an emergent worldwide pandemic, an outbreak whose unprecedented consequences highlighted many existing flaws within public healthcare systems across the world. While coronavirus disease 2019 (COVID-19) is bestowed with a broad spectrum of clinical manifestations, involving the vital organs, the respiratory system transpires as the main route of entry for SARS-CoV-2, with the lungs being its primary target. Of those infected, up to 20% require hospitalization on account of severity, while the majority of patients are either asymptomatic or exhibit mild symptoms. Exacerbation in the disease severity and complications of COVID-19 infection have been associated with multiple comorbidities, including hypertension, diabetes mellitus, cardiovascular disorders, cancer, and chronic lung disease. Interestingly, a recent body of evidence indicated the pulmonary and gut microbiomes as potential modulators for altering the course of COVID-19, potentially via the microbiome-immune system axis. While the relative concordance between microbes and immunity has yet to be fully elucidated with regards to COVID-19, we present an overview of our current understanding of COVID-19-microbiome-immune cross talk and discuss the potential contributions of microbiome-related immunity to SARS-CoV-2 pathogenesis and COVID-19 disease progression.

Frequency of Neurological Presentations of Coronavirus Disease in Patients Presenting to a Tertiary Care Hospital During the 2019 Coronavirus Disease Pandemic.

Background Coronavirus disease 2019 (COVID-19), caused by infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), usually presents clinically with cough, fever, shortness of breath, and loss of taste and/or smell. COVID-19 can also present with neurologic signs and symptoms, including headache, hyposmia/anosmia, encephalopathy, meningoencephalitis, Guillain-Barré syndrome, stroke, and seizure. Viral transmission occurs through aerosols generated when an infected person coughs, sneezes, or exhales and by direct touching of contaminated surfaces. The present study evaluated the frequency of neurologic presentations of coronavirus disease in patients presenting at a tertiary care hospital during the COVID-19 pandemic. Methodology This cross-sectional study included 350 inpatients and outpatients (self-isolated) with polymerase chain reaction-confirmed SARS-CoV-2 infection who presented at Dow International Medical College of Karachi between March and June 2020. Of these 350 patients, 68 (18.9%) presented with neurological signs and symptoms and were further evaluated. The data were analyzed statistically using IBM Statistical Product and Service Solutions (SPSS) for Windows, version 20.0 (IBM Corp., Armonk, NY). Results The 350 patients with SARS-CoV-2 infection included 245 (70%) men and 105 (30%) women; of these, 262 (74.9%) were married, and 88 (25.1%) were unmarried. Patients ranged in age from 17 to 88 years (mean ± standard deviation, 49.5 ± 17.4 years), with 68 (18.9%) having neurological manifestations. Headache was the most frequent neurological symptom, reported in 21 (6%) patients, followed by vertigo in 12 patients (3.4%), numbness/paresthesia in 11 (3.1%), altered level of consciousness in seven (2%), hyposmia/anosmia in five (1.4%), and encephalitis in three (0.9%). Other symptoms included sudden hemiparesis (stroke) in two patients (0.6%), flaccid paralysis due to Guillain-Barre syndrome in one (0.3%), and seizure in one (0.3%). Conclusion Neurological involvement is not infrequent in patients with COVID-19. Neurologic manifestations should be carefully monitored in infected patients. COVID-19 should be suspected in patients presenting with neurological abnormalities and should be included in the differential diagnosis to prevent further virus transmission.

Atomoxetine improves hippocampal cell proliferation but not memory in Doxorubicin-treated adult male rats.

Atomoxetine (ATX) is a noradrenaline reuptake inhibitor used to treat Attention deficit hyperactive disorder (ADHD), or improve cognition in normal subjects. Cancer patients treated with systemic adjuvant chemotherapy have described experiencing deterioration in cognition. Doxorubicin (DOX, Adriamycin) is one of the anthracycline families used in chemotherapy, which has a deteriorating effect on both cognition and proliferation. The cognitive effects of ATX require inputs from the hippocampus. The aim of this study was to examine spatial memory and proliferation in the subgranular zone (SGZ) of the DG in adult Lister Hooded rats treated either alone or with a combination of Atomoxetine (30 mg kg-1  day-1 , six i.p. doses, one injection every other day) and Doxorubicin (DOX) ( 2 mg kg-1  day-1 , six i.p. doses, one injection every other day). Spatial memory was tested using the Novel location recognition (NLR) test, and proliferation of hippocampal cells was quantified using immunohistochemistry for the proliferative marker Ki67. Results showed that ATX treatment has improved the NLR task and increased cell proliferation in the SGZ of the DG, compared with saline-treated controls. Animals treated with DOX only showed deficits in NLR task, and co-administration of ATX along with DOX did not improve their performance. DOX chemotherapy caused a significant reduction in the number of proliferating cells in the SGZ of the DG compared with saline-treated controls. This reduction was reversed by co-administration of ATX. The above findings suggest that DOX can negatively affect both cell proliferation and memory and ATX co-administration improves proliferation, but not memory in the adult male rat hippocampus.
