Severe headache, seizures and supraventricular tachycardia in a 33-year-old Filipino male with confirmed COVID-19: A case report

@#COVID-19 primarily presents as a pulmonary problem, ranging from mild respiratory illness to fatal acute respiratory distress syndrome. Most common manifestations are fever (89%) and cough (72%), while headache and arrhythmia are found in 28% and 17%, respectively. We aim to present a confirmed COVID-19 case presenting with both neurologic and cardiac manifestations. A 33-year-old Filipino male nurse initially consulted at the emergency room due to progressive diffuse headache, with associated localized seizures progressing to generalized tonic clonic seizure and arrhythmia. He had no coryza, cough, sore throat, and diarrhea. He was previously well and had no known co-morbidities or direct exposure to confirmed COVID-19 patients. Physical examination showed elevated blood pressure, tachycardia, and sensory and motor deficits in the left upper and lower extremities. Pertinent diagnostic test results included the detection of SARS-CoV-2 viral RNA via RT-PCR. Imaging studies demonstrated cortical venous thrombosis with hemorrhagic venous infarction in the right parietal lobe. Ground glass appearance on the middle lobe of the left lung was also evident. ECG showed supraventricular tachycardia. Prothrombin time, activated partial thromboplastin time, and D-dimer were all within the normal limits. Carotid massage was done. He was treated with anti-epileptics, anticoagulants, antiarrhythmics, antivirals, antibiotics, and supportive management. During the hospital stay, his symptoms resolved; he was discharged after 21 days. Follow-up done after 3 weeks revealed no recurrence of severe headache, seizure, or tachycardia. It is theorized that an interplay exists between ACE-2 tropism, systemic inflammation, cytokine storm, and hypoxemia in the background of COVID-19 infection. These mechanisms may lead to thrombosis and arrhythmia resulting to neurologic derangements and myocardial injury. Underlying mechanisms make the cerebro-cardiovascular systems vulnerable to the coronavirus disease 2019 infection. COVID-19 should therefore be part of the differential diagnoses in patients presenting with headache, seizures, and arrhythmias.

Prevalence and trends of mental disorders requiring inpatient care in the city of Porto Alegre: a citywide study including all inpatient admissions due to mental disorders in the public system from 2013-2017 / Prevalência e tendências temporais de transtornos mentais necessitando de tratamento de internação na cidade de Porto Alegre: um estudo de toda a cidade incluindo todas as internações por motivo de saúde mental no sistema público de 2013-2017

Abstract Objectives To investigate the 5-year prevalence of patients admitted to public inpatient care units due to a mental disorder, stratifying them by age group and diagnosis, and to assess trends of admissions over this time period in Porto Alegre. Methods All admissions to the public mental health care system regulated by the city-owned electronic system Administração Geral dos Hospitais (AGHOS) were included in the analysis. The total population size was obtained by estimations of Fundação de Economia e Estatística (FEE). General information about 5-year prevalence of inpatient admissions, time-series trends e prevalence by age groups and diagnosis were presented. Results There were 32,608 admissions over the 5-year period analyzed. The overall prevalence of patients was 1.62% among the total population, 0.01% among children, 1.12% among adolescents, 2.28% among adults and 0.93% among the elderly. The most common diagnosis was drug-related, followed by mood, alcohol-related and psychotic disorders. There was a linear trend showing an increase in the number of admissions from 2013 to the midst of 2014, which dropped in 2015. Conclusions Admissions due to mental disorders are relatively common, mainly among adults and related to drug use and mood disorders. Time trends varied slightly over the 5 years. Prevalence rates in real-world settings might be useful for policymakers interested in planning the public mental health system in large Brazilian cities.

Histological Effect of Basic Fibroblast Growth Factor on Chronic Vocal Fold Scarring in a Rat Model

OBJECTIVES: Vocal fold scarring is one of the most challenging laryngeal disorders to treat and there are currently no consistently effective treatments available. Our previous studies have shown the therapeutic potential of basic fibroblast growth factor (bFGF) for vocal fold scarring. However, the histological effects of bFGF on scarred vocal fold have not been elucidated. The aim of this study was to examine the histological effects of bFGF on chronic vocal fold scarring. METHODS: Sprague-Dawley rats were divided into phosphate buffered saline (sham) and bFGF groups. Unilateral vocal fold stripping was performed and the drug was injected into the scarred vocal fold for each group 2 months postoperatively. Injections were performed weekly for 4 weeks. Two months after the last injection, larynges were harvested and histologically analyzed. RESULTS: A significant increase of hyaluronic acid was observed in the vocal fold of the bFGF group compared with that of the sham group. However, there was no remarkable change in collagen expression nor in vocal fold contraction. CONCLUSION: Significant increase of hyaluronic acid by local bFGF injection was thought to contribute to the therapeutic effects on chronic vocal fold scarring.

A Simple Scalable Association Hypothesis Test Combining Gene-wide Evidence from Multiple Polymorphisms.

Aims: In single-nucleotide polymorphism (SNP) scans, SNP-phenotype association hypotheses are tested, however there is biological interpretation only for genes that span multiple SNPs. We demonstrate and validate a method of combining gene-wide evidence using data for high-density lipoprotein cholesterol (HDLC). Methodology: In a family based study (N=1782 from 482 families), we used 1000 phenotype-permuted datasets to determine the correlation of z-test statistics for 592 SNPHDLC association tests comprising 14 genes previously reported to be associated with HDLC. We generated gene-wide p-values using the distribution of the sum of correlated zstatistics. Results: Of the 14 genes, CETP was significant (p=4.0×10-5 <0.05/14), while PLTP was significant at the borderline (p=6.7×10-3 <0.1/14). These p-values were confirmed using empirical distributions of the sum of χ2 association statistics as a gold standard (2.9×10-6 and 1.8×10-3, respectively). Genewide p-values were more significant than Bonferronicorrected p-value for the most significant SNP in 11 of 14 genes (p=0.023). Genewide p- values calculated from SNP correlations derived for 20 simulated normally distributed phenotypes reproduced those derived from the 1000 phenotype-permuted datasets were correlated with the empirical distributions (Spearman correlation = 0.92 for both). Conclusion: We have validated a simple scalable method to combine polymorphism-level evidence into gene-wide statistical evidence. High-throughput gene-wide hypothesis tests may be used in biologically interpretable genomewide association scans. Genewide association tests may be used to meaningfully replicate findings in populations with different linkage disequilibrium structure, when SNP-level replication is not expected.

The utility of p16 INK4a and Ki-67 to identify high-grade squamous intraepithelial lesion in adolescents and young women.

Background: The repair of the immature squamous epithelium following HPV infection may mimic HSIL in adolescent women. Aim: to study the utility of p16 INK4a and Ki-67 in diagnosis of cervical squamous lesions in adolescents and young adults. Materials and Methods: In a cross-sectional study, the evaluation of p16 INK4a and Ki-67 immunohistochemistry was performed on 72 cervical biopsies of adolescents and young adults women diagnosed as negative for malignancy and intraepithelial lesion (NML) (n = 18) or positive for low grade (LSIL) (n = 31) and high grade (HSIL) (n = 23) squamous intraepithelial lesions in two references services in Fortaleza-Brazil. Data was evaluated using Fisher's test and Kappa index. Results: p16 INK4a was positive in 81% of HSIL, 19% of LSIL and in no NML (P < 0.0001). Ki-67 was positive in 74%, 32% and 5.5% of HSIL, LSIL and NML, respectively. p16 INK4a and Ki-67 in the diagnosis of HSIL showed high sensitivity and negative predictive value. Kappa index was very good for p16 INK4a (k = 0.72). Conclusions: In adolescents and young adults p16 INK4a alone or with Ki-67 represents important tool to reduce mistaken diagnosis of HSIL and to avoid overtreatment.

Extension du depistage du cancer du col uterin par inspection visuelle aux centres de sante communautaire du District de Bamako

Le cancer du col de l'uterus demeure un probleme de sante publique dans les pays en developpement. Le present travail constitue un bilan d'une etude multicentrique basee sur l'inspection visuelle du col apres application d'acide acetique (IVA) et de lugol (IVL). L'objectif assigne a ce travail est de determiner la faisabilite et l'impact de ce depistage au niveau des centres de sante communautaires du district de Bamako. Il s'agissait d'une etude prospective multicentrique a travers 8 CSCOM; 3 Centres de Sante de Reference (CSRef); l'Hopital Gabriel Toure (HGT) et l'Institut National de Recherche en Sante Publique (INRSP) de Bamako. Sur une periode de 28 mois; 5016 femmes agees de 25 a 49 ans ont ete depistees. Apres un consentement eclaire; la fiche d'enquete est remplie. La patiente etait confortablement installee sur une table gynecologique pour le depistage. La repartition des femmes depistees selon le niveau de la pyramide sanitaire se fait comme suit : CSCOM (19;24: 965/5016); CSRef (48;64: 2440/5016); HGT (32;12: 1611/5016). De facon generale; la positivite des tests etait la suivante : 5;2pour l'IVA et 6;8pour l'IVL. Les femmes positives au niveau des CSCOM etaient orientees vers un CSRef ou l'HGT pour la colposcopie; une biopsie eventuelle et la prise en charge. Sur 177 biopsies effectuees; les diagnostics suivants ont ete observes : 67 dysplasies; 3 carcinomes micro-invasifs; 69 carcinomes invasifs et 38 lesions inflammatoires; metaplasiques ou non concluantes. Les patientes presentant des lesions dysplasiques ou tumorales ont ete traitees par cryotherapie; conisation; resection a l'anse diathermique ou par la chirurgie. Ce travail montre que le depistage du cancer du col par les methodes visuelles est realisable au niveau des CSCOM. Nous recommandons une large diffusion de la methode sur tout le territoire national

Quantification of 20-hydroxyeicosatetraenoic acid by colorimetric competitive enzyme linked immunosorbent assay.

Analysis of 20-hydroxyeicosatetraenoic acid (20-HETE), a potent vasoconstrictor produced by the cytochrome P450 pathway, presently requires high-performance liquid chromatography (HPLC) and gas chromatography/ mass spectrometry (GC/MS). To simplify 20-HETE analysis, competitive ELISAs were developed using polyclonal anti-20-HETE coated ELISA plates to which free 20-HETE and 20-HETE conjugated to horseradish peroxidase (HRP) or alkaline phosphatase (AP) were added. Assays were developed with and without a pro prietary enhancer solution which allows for the extraction-free measurement of 20-HETE in urine samples. The bound 20-HETE-HRP or 20-HETE-AP was detected using 3,3 ,5,5, -tetramethylbenzidine and p-nitrophenyl phosphate, respectively. Sensitivities expressed as 80% B/B0, were 0.1 ng/ml for the HRP assay, and 0 5 ng/ml for the AP assay, with r2 = 0 99 for both formats. Of the 17 lipids tested for cross-reactivity, arachidonic acid showed the highest (0.32%) followed by racemic 5-HETE (0.07%) and 8,9-dihydroxyeicosatrienoic acid (DHET) (0.04%). Preliminary validation experiments examining serum and urine concentrations of 20-HETE yield values that fall within the ranges established by GC/MS in the literature. These ELISAs provide simple and inexpensive methods for the analysis of 20-HETE in biological samples.
