This retrospective study assessed the diagnostic performance of ultrasonography in detecting hypertrophic pyloric stenosis (HPS) among 160 infants presenting with non-bilious vomiting. With surgical outcomes and clinical follow-up serving as reference standards, ultrasound demonstrated a sensitivity of 88% and specificity of 80%. Pyloric muscle thickness was the most reliable sonographic parameter, with a ≥3.0 mm threshold significantly associated with true HPS cases (p=0.03). ROC curve analysis affirmed its high diagnostic utility, yielding an AUC of 0.94. While most cases correlated well between sonographic and surgical findings, diagnostic discordance—often due to pylorospasm or technical limitations—highlighted the importance of standardized imaging protocols. These findings support ultrasound as a valuable,non-invasive diagnostic modality in pediatric care and emphasize the need for operator expertise and consistent measurement techniques to optimize clinical outcomes.

This cross-sectional observational study evaluated 166 adult patients with Type 2 Diabetes Mellitus (T2DM) to assess the prevalence of thyroid dysfunction (TD) and its association with diabetic complications. The study found that 24.69% of the cohort had TD, with hypothyroidism—both overt (13.25%) and subclinical (10.24%)—being the most prevalent, and hyperthyroidism observed in only 1.2% of cases. Thyroid dysfunction was notably more common in females and significantly associated with obesity (p=0.0006), poor glycemic control (HbA1c >7%; p=0.009), dyslipidemia (p=0.01), albuminuria (p=0.02), and diabetic retinopathy (p=0.01). Patients with TD also had higher HbA1c levels compared to their euthyroid counterparts, indicating worsened glycemic control. Although neuropathy and hypertension were more frequent in the TD group, their associations were not statistically significant.

This prospective observational study evaluated the prognostic role of NT-proBNP levels in 100 patients under 60 years of age diagnosed with Acute Coronary Syndromes (ACS), including STEMI, NSTEMI, and unstable angina. NT-proBNP, a biomarker reflecting myocardial wall stress, was measured within 2–24 hours of symptom onset and stratified into three groups: <100 pg/mL, 100–500 pg/mL, and >500 pg/mL. Clinical outcomes over six months—such as recurrent chest pain, dyspnea, palpitations, rehospitalizations, left ventricular (LV) dysfunction, myocardial infarction, and all-cause mortality—were recorded. Elevated NT-proBNP levels were significantly associated with adverse events: patients with >500 pg/mL exhibited the highest incidence of LV dysfunction (72%), recurrent MI (60%), and mortality (28%), while no deaths occurred in those with levels <100 pg/mL. NT-proBNP levels above 100 pg/mL were strong predictors of recurrent ischemia and compromised cardiac function.

This retrospective study assessed 244 living donor kidney transplants to examine how the donor kidney volume-to-recipient body surface area (Vol/BSA) ratio influences graft outcomes. Donor kidney volume was measured using preoperative CT scans, while recipient BSA was calculated via the Mosteller formula. The Vol/BSA ratio was found to be an independent predictor of 12-month estimated glomerular filtration rate (eGFR), alongside recipient age and sex. Recipients in the highest Vol/BSA tertile had significantly better graft function (mean eGFR 75.95 mL/min/1.73 m²) compared to those in lower tertiles. Despite no significant difference in complication rates such as rejection or delayed graft function, the study supports the concept of “nephron dosing,” suggesting that larger donor kidneys relative to recipient size improve metabolic balance and reduce hyperfiltration risk.

This prospective study evaluated postoperative pain in 97 patients undergoing Retrograde Intrarenal Surgery (RIRS) for kidney stones, with the goal of identifying factors predictive of severe pain. Pain intensity was assessed at 6, 12, and 24 hours postoperatively using the Visual Analogue Scale (VAS), categorizing patients into mild (VAS <7) and severe (VAS ≥7) pain groups. While no significant associations were found between demographic or stone-related factors (age, gender, stone size, location, density) and pain severity, two technical factors stood out. The use of smaller-diameter ureteral access sheaths (p=0.027) and sheath indwelling times exceeding 60 minutes (p=0.043) were significantly associated with higher postoperative pain levels. These findings suggest that minimizing intraoperative ureteral manipulation and optimizing sheath parameters can help reduce postoperative discomfort.

This retrospective study analyzed 105 gunshot injury cases admitted to a tertiary care hospital to identify demographic patterns, clinical characteristics, and outcomes. Young adult males (90.5%) were disproportionately affected, with most injuries occurring at night (73.3%) and nearly equal rural–urban distribution. Lower limb wounds were most common (62.9%), and 78.1% of patients had exit wounds. The leading contexts were police-related shootings (52.4%) and homicides (45.7%), while suicides were rare (1.9%). Surgical intervention was necessary in only 6.7% of cases, likely due to the predominance of peripheral injuries or rapid fatality from severe trauma. Despite a high overall survival rate (91.4%), fatalities were primarily associated with head and abdominal wounds.

This prospective study compared low-dose mifepristone (5 mg/day) and the levonorgestrel intrauterine system (LNG-IUS) in 74 premenopausal women with symptomatic adenomyosis over six months. Both treatments led to significant reductions in uterine volume, menstrual blood loss, and dysmenorrhea, with no statistically significant difference between groups at the study's conclusion. While LNG-IUS showed a faster initial reduction in bleeding, both therapies achieved similar improvements in hemoglobin levels and quality of life. Adverse effects were mild in both arms, with only one case of device expulsion. These findings suggest that both low-dose mifepristone and LNG-IUS are safe, effective, and conservative options for adenomyosis management.

This cross-sectional study examined 400 women aged 45–60 to assess the association between vasomotor symptoms (VMS)—such as hot flashes and night sweats—and cardiovascular risk in perimenopausal and postmenopausal stages. Moderate to severe VMS were significantly linked with higher systolic and diastolic blood pressure, increased LDL cholesterol and triglycerides, and elevated fasting glucose levels. These associations remained even after adjusting for age, smoking, and BMI. Notably, frequent night sweats were associated with a greater risk of metabolic syndrome. Perimenopausal women with severe VMS showed more pronounced cardiovascular changes than postmenopausal women. However, women who exercised regularly demonstrated lower risk profiles despite similar VMS severity. The findings suggest that VMS are not just quality-of-life concerns.

This retrospective study highlights the role of high-resolution computed tomography (HRCT) in evaluating cholesteatoma and its complications. Seven patients (mean age: 30.4 years) with suspected cholesteatoma underwent HRCT of the temporal bone. All cases demonstrated characteristic findings such as ossicular chain erosion (100%), scutum erosion (86%), and involvement of the facial nerve canal (43%). One case involved an external auditory canal cholesteatoma—an uncommon presentation. HRCT proved crucial in identifying disease extent, detecting complications like labyrinthine destruction and facial nerve canal dehiscence, and aiding surgical planning. The radiological findings strongly correlated with intraoperative and histopathological observations.
