Better Late Than Never: Definitive Anatomic Repair of Dextro-Transposition of the Great Arteries.

We present a case of anatomic repair of dextro-transposition of the great arteries (d-TGA) with ventricular septal defect (VSD) in a 55-year-old man who presented with acute heart failure. This case highlights the importance of multimodal imaging and multidisciplinary involvement in developing a comprehensive surgical and medical plan for adults with congenital heart disease. We think this is the oldest reported patient undergoing anatomic surgical repair of d-TGA with VSD.

All Eyes and Ears: A Case of Neurosyphilis Presenting With Simultaneous Ocular and Otic Involvement.

This report details a case of neurosyphilis manifesting as concurrent ocular and otosyphilis, an uncommon presentation of the disease. Here, we describe the diagnosis and treatment of a 27-year-old immunocompetent Caucasian male who presented with uveitis and tinnitus. Physical exam was consistent with uveitis and audiometric testing revealed bilateral sensorineural hearing loss. Serum rapid plasma reagin (RPR) was reactive at 1:512 with a follow-up cerebrospinal fluid (CSF) venereal disease research laboratory (VDRL) test likewise reactive at 1:2, confirming neurosyphilis. The patient was treated with intravenous penicillin G with improvement of symptoms and with subsequent improvement of serum and CSF RPR. However, he ultimately represented with recurrent symptoms and fluctuating serum RPR levels, necessitating repeat treatment and ongoing clinical monitoring. Neurosyphilis can occur at any point during the course of a syphilis infection and may present with a variety of nonspecific findings. This case documents a particularly uncommon instance of simultaneous ocular and otosyphilis, a presentation of neurosyphilis that has only been described a handful of times.

VDR gene polymorphisms are associated with the increased susceptibility to COVID-19 among iranian population: A case-control study.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but the pathogenesis is unclear. Host genetic background is one of the main factors influencing the patients' susceptibility to several viral infectious diseases. This study aimed to investigate the association between host genetic polymorphisms of two genes, including vitamin D receptor (VDR) and vitamin D binding protein (DBP), and susceptibility to COVID-19 in a sample of the Iranian population. This case-control study enrolled 188 hospitalized COVID-19 patients as the case group and 218 suspected COVID-19 patients with mild signs as the control group. The VDR (rs7975232, rs731236 and rs2228570) and DBP (rs7041) gene single nucleotide polymorphisms (SNPs) were genotyped by Polymerase Chain Reaction Restriction - Fragment Length Polymorphism (PCR-RFLP) method. A significant association between rs2228570 SNP in the VDR gene and the susceptibility of COVID-19 was found between case and control groups. The CT genotype (Heterozygous) of rs2228570 C > T polymorphism showed significant association with a 3.088 fold increased odds of COVID-19 (p < .0001; adjusted OR: 3.088; 95% CI: 1.902-5.012). In addition, a significant association between CC genotype of rs2228570 CT polymorphism and increased odds of COVID-19 in male and female groups (p = .001; adjusted OR: 3.125; 95% CI: 1.630-5.991 and p = .002; adjusted OR: 3.071; 95% CI: 1.485-6.354 respectively) were determined. Our results revealed no significant differences in the frequency of genotype and allele of VDR (rs7975232 and rs731236) and DBP (rs7041) between SARS-CoV-2-infected patients and controls (p > .05). Our results showed that polymorphism of VDR (rs2228570) probably could influence individual susceptibility to COVID-19. The polymorphisms of VDR (rs7975232 and rs731236) and DBP (rs7041) were not associated with SARS-CoV-2 infection susceptibility.

Prevalence of occult hepatitis B virus infection among the blood donors in Golestan province: cross-sectional study.

Background and Objectives: Despite the increased sensitivity of screening tests, the HBV can be transmitted during the window period and occult hepatitis B infection. The purpose of this study was to evaluate HBV markers and prevalence of OBI among HBsAg negative blood donors in Golestan province. Materials and Methods: Anti-HBc (IgM and IgG), anti-HBs and anti-HBe tests on 4313 serum samples (HBsAg negative) were performed by ELISA method. Also, all samples for the presence of HBV-DNA were tested by using NAT methods. SPSS software and chi-square test were used for data analysis. Results: Of the 4313 samples, 384 (8.9%) sera were anti-HBc positive. Also, of 384 anti-HBc positive samples, 302 (78.65%) were anti-HBs positive and 152 (39.6%) were anti-HBe positive. Thirty-nine (0.90%) samples were anti-HBc positive, anti-HBs negative and anti-HBe negative. HBV-DNA was not detected in any of specimens. Conclusion: Based on the results of retesting the isolated anti-HBc samples that after one year recalling, had undetectable HBV-DNA and for the prevention of the decreasing of healthy blood donation (due to false positive anti-HBc) and preservation of the blood supplies; Individual Donor Nucleic Acid Testing (ID-NAT) along with the anti-HBc testing for the improving blood safety is recommended.

Prevalence and phylogenetic analysis of HTLV-1 in blood donors in Golestan Province, in the Northeast of Iran.

The human T-lymphotropic virus type 1 (HTLV-1) can cause ATL or TSP. This study evaluates the prevalence of HTLV-1 infection in blood donors in Golestan province. The study was conducted among 4226 blood donors and ELISA test was performed for the initial HTLV-1 screening. Reactive samples were confirmed by Western blot and Electrochemiluminescence tests. Then recalling donors with reactive results was done and genomic DNA from the new sample was extracted and tested using the Nested PCR method and phylogenetic analysis was performed. At first, 8 samples were reactive with ELISA test and 4 samples were confirmed with western blot, Electrochemiluminescence and Nested PCR tests.The sequences of isolates was related to the HTLV-1 virus and subtype a (cosmopolitan) subgroup A.The prevalence of HTLV-1 virus in Golestan province was about 0.09 %.The genotype of virus isolates had a common ancestor with isolates of the Khorasan region.
