Correlation of Histopathological and Radiological Response Patterns and Their Prognostic Implications in Breast Cancer After Neoadjuvant Chemotherapy.

Purpose: In breast cancer (BC), neoadjuvant chemotherapy (NAC) responses can be categorized as concentric shrinkage (CS), non-concentric shrinkage (non-CS), and complete response, influencing surgical planning and survival. This study evaluates the correlation between histopathological and radiological response patterns in BC patients after NAC and their impact on overall survival (OS) and disease-free survival (DFS).

Patients And Methods: This retrospective study analyzed 168 BC patients who received NAC between 2018 and 2022.

Diagnostic performance of multishot echo-planar imaging (RESOLVE) and non-echo-planar imaging (HASTE) diffusion-weighted imaging in cholesteatoma with an emphasis on signal intensity ratio measurement.

Purpose: To evaluate the diagnostic efficacy of multishot echo-planar imaging (EPI) [RESOLVE (RS)] and non-EPI (HASTE) diffusion-weighted imaging (DWI) in detecting cholesteatoma (CHO), and to explore the role of signal intensity (SI) ratio measurements in addressing diagnostic challenges.

Methods: We analyzed RS-EPI and non-EPI DWI images from 154 patients who had undergone microscopic middle ear surgery, with pathological confirmation of their diagnoses. Two radiologists, referred to as Reader A and Reader B, independently reviewed the images without prior knowledge of the outcomes.

Ultrasonographic Characteristics of Thyroid Nodules with Nondiagnostic and Atypia of Undetermined Significance in Fine-Needle Aspiration Cytology.

Objectives: This study aimed to investigate ultrasound (US) features of thyroid nodules categorized as nondiagnostic (ND) and atypia of undetermined significance (AUS) according to the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) and their potential implications for clinical management.

Materials And Methods: A retrospective study was conducted on patients who underwent thyroid nodules FNAC between 2019 and 2023. Nodules falling into the ND and AUS categories were analyzed for US features, nodule size, composition, echogenicity, shape, margin, echogenic foci, the distribution of the American College of Radiology's Thyroid Imaging Reporting and Data System (ACR TI-RADS) categories, and other parameters.

Hepatobiliary-Specific MRI Contrast Agent Detection of Subvesical Duct (Luschka's) Injury Post-Laparoscopic Cholecystectomy: A Case Report.

Post-laparoscopic cholecystectomy bile duct injuries, especially involving Luschka's duct, are concerning. Biliary tree anomalies and the efficacy of intravenous administration of Gd-EOB-DTPA-enhanced magnetic resonance imaging (MRI) in detecting bile leakage are reported based on a case. Hepatobiliary-specific MRI-contrast agents prove valuable for noninvasive assessment of bile leakage after cholecystectomy.

Case Presentation of Duodenal Obstruction Caused by Complete Annular Pancreas.

A complete annular pancreas, a rare congenital anomaly, can lead to duodenal obstruction, causing recurrent symptoms like vomiting and often requiring surgical intervention for relief.

Long-Term, Self-Dosing CBD Users: Indications, Dosage, and Self-Perceptions on General Health/Symptoms and Drug Use.

Introduction: Self-dosing of off-the-shelf cannabidiol (CBD) for a myriad of health conditions is common in the USA. These CBD products are often mislabeled, suggesting that much less or much more CBD is being consumed than indicated on the label. This study examined the relationship between long-term self-dosing of CBD and (a) indications and, when a verified concentration of CBD is being consumed, (b) the daily CBD dosage, (c) the impact on general health and symptoms, and (d) over-the-counter (OTC) and prescription (Rx) drug usage.

Liver Pseudotumor Due to Aberrant Left Gastric Vein: A Case Report.

Unlabelled: Liver pseudotumors (pseudolesions) pose diagnostic challenges in imaging, often linked to anomalous venous drainage. Notably, aberrant left gastric vein (ALGV) plays a role in segment 2 and 3 pseudolesions. A liver parenchymal pseudolesion due to abnormal venous drainage involving ALGV is highlighted.

Diagnostic value of adenosine deaminase activity in pericardial fluids.

Background: The activity of adenosine deaminase (ADA) was determined in serum and pericardial fluid of 70 patients (ages 21 to 71 years) with pericardial effusions of various etiologies and in 15 control subjects.

Methods: The patients were subdivided into five groups on the basis of definite diagnosis: 1) 24 patients with tuberculosis; 2) 22 with malignancies; 3) 12 with uremic pericarditis; 4) 12 with purulent pericarditis; 5) 15 control individuals without pericardial disease. The activity of ADA was determined at the same time in serum and cell-free pericardial fluid according to the method of Karker with minor modification.

Surgical management of congenital lobar emphysema.

Here in nine patients with congenital lobar emphysema who had been treated surgically in the previous 10 years are reported. The ages of the patients at diagnosis ranged from 26 days to 11 months. The six patients whose symptoms started in the neonatal period had more severe dyspnea, cyanosis and respiratory distress.

Atrial fibrillation after coronary artery bypass surgery: predictors and the role of MgSO4 replacement.

Background: Supraventricular arrhythmias continue to complicate the postoperative course of patients undergoing myocardial revascularization. The aim of the study was to identify factors associated with atrial fibrillation (AF) and to determine the efficacy of postoperative magnesium sulphate (MgSO4) replacement on the incidence of AF after coronary artery bypass grafting (CABG) operation.

Methods: Fifty patients undergoing CABG were studied prospectively.

Coarctation of the abdominal aorta with left renal artery and splenic artery aneurysms.

Both coarctation of the abdominal aorta, and splenic artery aneurysm reside in the hilus, a rare but extremely important pathological condition. Herein a 36-year-old woman hospitalized for uncontrolled hypertension is presented. Aortography demonstrated segmental abdominal aortic coarctation with left renal artery and splenic artery aneurysms.

Coarctation of the aorta in infants and neonates: results and assessment of prognostic variables.

From 1984 until 1994, 75 consecutive patients younger than 12 months of age were operated on for coarctation of the aorta. We retrospectively analyzed predictive factors for morbidity and mortality, and also interaction between surgical procedures and recoarctation. Surgical procedures were as follows: resection with a traditional end-to-end (E-E) anastomosis in 55 patients (73.

Left ventricular size following shunt operation in tetralogy of Fallot.

This study was performed in 24 patients with tetralogy of Fallot in whom shunt operation was performed instead of total correction because of small left ventricular end-diastolic dimension. Left ventricular end-diastolic dimension was measured using M-mode and two-dimensional echocardiography pre- and at least one year postoperatively. There was no change in the postoperative left ventricular size in two patients.

Long-term experience with pericardiectomy: analysis of 105 consecutive patients.

A retrospective analysis of the records of 105 patients who underwent pericardiectomy from 1983 to 1993 was performed. Primarily, 40 patients (38%) had tuberculosis, 16 patients (15%) a malignancy, 12 patients (11.4%) uremia, and 11 patients (10.

The influence of pulmonary insufficiency on ventricular function following total correction of Fallot's tetralogy: evaluation using radionuclide ventriculography and clinical findings.

Long-standing pulmonary insufficiency after repair of tetralogy of Fallot may adversely affect ventricular function. We evaluated 20 patients postoperatively by radionuclide ventriculography and clinical findings after total correction of tetralogy of Fallot. Patients were divided into two groups as follows: Group I patients (10) had no pulmonary insufficiency; Group II patients (10) had moderate or severe pulmonary insufficiency.

Surgical treatment in tetralogy of Fallot diagnosed by echocardiography.

The purpose of this paper is to present the authors' 3-yr experience of echocardiographic examination of patients with the clinical diagnosis of tetralogy of Fallot, and their evaluation for surgical treatment without prior cardiac catheterization. Among the patients with the clinical diagnosis of tetralogy of Fallot 227 had a definite diagnosis made by M-mode, two-dimensional, Doppler and contrast echocardiography. For the diagnosis of tetralogy of Fallot, ventricular septal defect, pulmonary stenosis, and overriding of the aorta were considered to be fundamental.
