Streptococcus dysgalactiae has two main subspecies: Streptococcus dysgalactiae subsp. equisimilus (SDSE) and Streptococcus dysgalactiae subsp. dysgalactiae (SDSD). The vast majority of human infections belonging to Streptococcus dysgalactiae have been associated with SDSE. There are only three cases of SDSD found in humans in literature. We present a case of SDSD cellulitis and bacteremia in a 49-year-old female patient from Houston, Texas with no major exposure to animals or trauma.

Introduction Diabetes mellitus (DM) is a significant and common risk factor for the development of peripheral vascular disease (PVD). Peripheral vascular disease is the atherosclerotic narrowing of peripheral arteries and has a high prevalence among patients with diabetes. Material and methods A cross-sectional study was conducted in the Department of Medicine of Ayub Teaching Hospital, Abbottabad. A total of 271 diagnosed diabetic patients aged 40 years or above were included in the study. Ankle-brachial pressure index (ABPI) was measured using a hand-held Doppler device and sphygmomanometer. An ABPI < 0.9 was taken to be abnormal. The risk factors were noted through history taking, physical examination, and appropriate investigations. Results Our study sample included 271 patients. A hundred and forty-five (53.5%) of them were males, and 126 (46.5%) were females. Fifty-three (19.9%) out of 271 patients had peripheral vascular disease. The prevalence of peripheral vascular disease was stratified among smoking (p=0.00), hypertension (p=0.00), obesity (p=0.004), and hypercholesterolemia (p=0.005) to determine if there was any association between these and peripheral vascular disease. A p-value less than 0.05 was taken to be significant. Conclusion This study showed a significant association between PVD and smoking, hypertension, hypercholesterolemia, and obesity.

Nipah virus (NiV) is a deadly virus with a high mortality rate that has affected many developing countries in the past. According to the Centers for Disease Control and Prevention (CDC), many economically deprived countries such as Madagascar, Cambodia, and Thailand are also at high risk for future outbreaks. The first case of NiV was reported in 1998 and almost two decades later, little scientific progress has been made in finding a proper treatment and prevention vaccine. As many developing countries are not properly equipped to fight the infection, it is vital to properly educate the health systems. The aim of this review is to provide an epidemiological background as well as to understand the transmission routes, presentation, and the diagnosis and prevention of this deadly virus.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is an increasingly prevalent condition linked to obesity, diabetes, and metabolic syndrome, and can progress to fibrosis, cirrhosis, and hepatocellular carcinoma. Current diagnostic standards such as liver biopsy are invasive and unsuitable for routine screening. Liquid biopsy, particularly through analysis of extracellular RNAs (exRNAs), including microRNAs (e.g., miR-122, miR-21, miR-34a), long non-coding RNAs, and tRNA-derived fragments, offers a promising non-invasive alternative. These exRNAs, released from hepatocytes and carried in blood via extracellular vesicles or protein complexes, can be detected using techniques like RNA sequencing, qRT-PCR, and droplet digital PCR. These biomarkers correlate with histologic severity, fibrosis stage, and treatment response, and have shown promising diagnostic utility; however, their performance may differ across various populations and disease stages. Despite their potential, clinical translation is limited by a lack of standardization and large-scale validation. This review outlines recent advances in exRNA-based diagnostics for MASLD and MASH, emphasizing their role in early detection, disease monitoring, and the shift toward personalized hepatology.

Y Congenital heart block is a grave condition reported in 0.5% of 100 live births. Systemic lupus erythematosus (SLE) and Sjogren's syndrome (SS) are chronic autoimmune and inflammatory condition, which affects multiple systems. The association of SLE and SS with pregnancy has been seen in the past. Usually, it shows anti-Ro/SSA and anti-Ro/SSB auto-antibodies in maternal serum, which is proportional to fetal Outcome. In this report, we present a case of a 29-year-old female gravida 4, para one and aborta 3, with a history of polycystic ovarian disease and multiple abortions. At 20 weeks of gestation, her antenatal examination revealed fetal bradycardia and heart block, which further led to SLE and SS diagnosis in her. She was treated with steroids to prevent further fetal complications. The patient delivered a healthy neonate at 38 weeks of gestation. The neonate eventually received a cardiac pacemaker and is now on regular follow-up.

The SARS-CoV-2 virus responsible for COVID-19 infection has affected the world from the end of 2019 with pulmonary and extrapulmonary manifestations. Hematologic complications are a rare but severe complication of the COVID-19 infection. There have been very few cases reported in the past showing thrombotic complications in the pediatric age group. We present a case of a 12-year-old male child showing cerebral venous sinus thrombosis (CVST) who tested positive for COVID-19 at the same time. We highlight the potential of this complication in the pediatric age group and discuss the treatment, which is an infrequent phenomenon.
