Bilateral Middle Cerebellar Peduncle Infarction Presenting With Vertigo and Hearing Impairment Mimicking Peripheral Vestibulopathy.

Bilateral middle cerebellar peduncle (MCP) infarction is a rare manifestation of ischemic stroke. We report a middle-aged male patient who presented with acute onset of vertigo, left ear deafness, and severe ataxia. Magnetic resonance imaging (MRI) of the brain confirmed the presence of infarction in the bilateral middle cerebellar peduncles due to stenosis of the posterior circulation arteries.

Undiagnosed Uterine Didelphys, Concomitant Right Renal Agenesis, and Left Nephrolithiasis in a Primigravida With Breech Pregnancy: A Case Report.

Mullerian duct anomalies are congenital abnormalities involving the female genital systems. A double uterus or uterine didelphys is one of the uterine duplication anomalies that result from impaired fusion with regard to the Mullerian ducts. The uterine didelphys can be diagnosed earlier in symptomatic patients.

Computed Tomography Findings in a Case of Uterine Rupture as a Complication of Pyometra.

Uterine rupture in the setting of pyometra is a rare occasion, with an incidence of less than 0.5%. The clinical manifestation of a perforated pyometra is non-specific; therefore, it can mimic many other causes of acute abdomen, such as perforated viscus, acute appendicitis, or diverticulitis, which poses unique challenges to diagnosis solely based on clinical information.

Adhesional Omental Hernia With Small Bowel Obstruction in an Elderly Patient With a Virgin Abdomen: A Case Report.

Small bowel obstruction is a frequently encountered surgical condition in adults. Its most prevalent causes include adhesions resulting from prior abdominal surgery or peritoneal infection. However, cases of small bowel obstruction caused by omental bands in elderly individuals with no prior abdominal surgeries are exceedingly rare, with only a few reported in the literature.

Comparative Analysis of Image Processing Techniques for Enhanced MRI Image Quality: 3D Reconstruction and Segmentation Using 3D U-Net Architecture.

Osteosarcoma is a common type of bone tumor, particularly prevalent in children and adolescents between the ages of 5 and 25 who are experiencing growth spurts during puberty. Manual delineation of tumor regions in MRI images can be laborious and time-consuming, and results may be subjective and difficult to replicate. Therefore, a convolutional neural network (CNN) was developed to automatically segment osteosarcoma cancerous cells in three types of MRI images.

Clinical symptoms of chronic rhinosinusitis with nasal polyps (eosinophilic and non-eosinophilic) are related to sinus computed tomography but not to endoscopic findings.

Background: In the clinical assessment of chronic rhinosinusitis with nasal polyps (CRSwNP), evaluation of symptoms, nasoendoscopy findings and sinus computed tomography (CT) scan staging is employed in the management plan. Although prior studies have been done to assess the correlation of the three modalities in CRSwNP, such evaluation in patients with eosinophilic and non-eosinophilic types of CRSwNP requires further investigation. The aim of this study was to correlate the sinus CT scan staging to symptom and endoscopic scores in both types of CRSwNP.

The Effect of Atopy on the Incidence of Osteitis in Patients with Chronic Rhinosinusitis.

The prevalence of frontal cell variants according to the International Frontal Sinus Anatomy Classification and their associations with frontal sinusitis.

Background: The International Frontal Sinus Anatomy Classification (IFAC) is introduced to simplify the classification of different frontal cell variants based on their topographical structures. The objectives of our study were to determine the prevalence of the frontal cell variants according to IFAC and their association with the development of frontal sinusitis.

Methodology: A retrospective chart review on computed tomography paranasal sinus (CTPNS) was conducted.

A new radiological classification for the risk assessment of anterior skull base injury in endoscopic sinus surgery.

Keros and Gera classifications are widely used to assess the risk of skull base injury during endoscopic sinus surgery. Although, both classifications are useful preoperatively to stratify risk of patients going for surgery, it is not practical to measure the respective lengths during surgery. In this study, we aimed to propose a new radiological classification (Thailand-Malaysia-Singapore (TMS)) to assess the anatomical risk of anterior skull base injury using the orbital floor (OF) as a reference.

Lifestyle practices and obesity in Malaysian adolescents.

Aim: To determine the influence of physical activity (PA) and sedentary behavior (SB) on obesity profiles of 454 Malaysian adolescents aged 12 to 19.

Methods: Validated PA and SB questionnaires were used and body composition assessed using anthropometry and dual-energy X-ray absorptiometry (DXA).

Results: Gender-specific multivariate analyses showed boys with high levels of total PA and moderate-to-vigorous physical activity (MVPA) exhibited significantly lower levels of total body fat, percent body fat and android fat mass compared with low PA and MVPA groups, after adjusting for potential confounders.

Relationship between anthropometric and dual energy X-ray absorptiometry measures to assess total and regional adiposity in Malaysian adolescents.

The main objective of this paper was to determine the utility of various anthropometric measures to assess total and regional body fatness using dual-energy X-ray absorptiometry (DXA) as the criterion in 454 adolescent boys and girls aged 12-19 years. Multivariable regression analyses of gender-specific and gender-combined models were used to determine anthropometric measures on DXA-derived body fatness models, after adjusting for known confounding biological factors. Partial correlation analyses, after adjusting for age, pubertal growth status and ethnicity in boys and girls, showed that body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-height ratio (WhtR) were significantly correlated with total body fat (TBF), percent body fat (%BF), android region fat (ARF) and trunk fat (TF) (all p<0.

Wavelet energy-guided level set-based active contour: a segmentation method to segment highly similar regions.

This paper introduces an approach to perform segmentation of regions in computed tomography (CT) images that exhibit intra-region intensity variations and at the same time have similar intensity distributions with surrounding/adjacent regions. In this work, we adapt a feature computed from wavelet transform called wavelet energy to represent the region information. The wavelet energy is embedded into a level set model to formulate the segmentation model called wavelet energy-guided level set-based active contour (WELSAC).
