Objective: To evaluate agreement in pathologic diagnosis of tissue obtained by colposcopic directed biopsy (CDB) and conization or total abdominal hysterectomy (TAH) in the diagnosis of cervical intraepithelial neoplasia (CIN).
Material And Method: Medical records of women with abnormal cervical cytology referred for colposcopic examination from January 1, 1999 to December 31, 2003 were reviewed. Agreement in diagnosis of CIN in tissue obtained by CDB and tissue obtained by conization or TAH is defined as not more than one level of CIN disparity.
Results: Agreement between pathologic diagnosis of tissue from CDB and tissue from conization or TAH is 67.1% with a 95% confidence interval of 57-77%. Six cases of invasive cancer were not diagnosed from CDB but subsequently diagnosed from conization.
Conclusion: Agreement between pathologic diagnosis of tissue obtained from CDB and tissue from conization or TAH in the present study was too low to accept CDB as a diagnostic modality for CIN in selected cases. Conization should be performed in these cases after diagnosis of CIN is made by CDB.

Effect of glyceryl trinitrate and clevidipine administration on CT angiogram findings in dogs undergoing prostatic artery embolization for prostatic carcinoma.
PLoS One
December 2024
Department of Surgical and Radiological Sciences, From the University of California-Davis, School of Veterinary Medicine, Davis, Davis, California, United States of America.
Objectives: The primary aim of this study was to evaluate the effects of vasodilator administration on CT angiography (CTA) prostatic artery diameter and peak opacification in dogs with prostatic carcinoma prior to prostatic artery embolization (PAE).
Materials And Methods: A prospective clinical trial was performed. Ten dogs with naturally occurring prostatic carcinoma and no evidence of cardiovascular disease were enrolled.
Race as a prognostic factor of breast mucinous carcinoma.

Department of Breast Surgery, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, 100021, China.
Purpose: The rarity of breast mucinous carcinoma (BMC) makes it challenging to study the prognosis of this disease across diverse racial populations. This study aimed to leverage epidemiological data on immigrant populations to elucidate the prognostic differences in BMC patients from various racial/ethnic backgrounds. The goal was to help formulate more personalized clinical practice guidelines for the management of this rare malignancy.

Tomography
December 2024
Centre for Research and Development, Uppsala University, Region Gävleborg, SE 801 88 Gävle, Sweden.
Background: This study aimed to assess the interobserver variability of semi-automatic diameter and volumetric measurements versus manual diameter measurements for small lung nodules identified on computed tomography scans.
Methods: The radiological patient database was searched for CT thorax examinations with at least one noncalcified solid nodule (∼3-10 mm). Three radiologists with four to six years of experience evaluated each nodule in accordance with the Fleischner Society guidelines using standard diameter measurements, semi-automatic lesion diameter measurements, and volumetric assessments.
Femoroacetabular Impingement Morphological Changes in Sample of Patients Living in Southern Mexico Using Tomographic Angle Measures.
Tomography
December 2024
Hospital Regional de Alta Especialidad de la Peninsula de Yucatan, Servicios de Salud del IMSS-BIENESTAR, Merida 97130, Yucatan, Mexico.
Background: Femoroacetabular impingement (FAI) is a condition caused by abnormal contact between the femur head and the acetabulum, which damages the labrum and articular cartilage. While the prevalence and the type of impingement may vary across human groups, the variability among populations with short height or with a high prevalence of overweight has not yet been explored. Latin American studies have rarely been conducted in reference to this condition, including the Mayan and mestizo populations from the Yucatan Peninsula.

Liver Int
January 2025
Department of Experimental and Clinical Medicine, University of Florence, Florence, Italy.
Background & Aims: GD2, a member of the ganglioside (GS) family (sialic acid-containing glycosphingolipids), is a potential biomarker of cancer stem cells (CSC) in several tumours. However, the possible role of GD2 and its biosynthetic enzyme, GD3 synthase (GD3S), in intrahepatic cholangiocarcinoma (iCCA) has not been explored.
Methods: The stem-like subset of two iCCA cell lines was enriched by sphere culture (SPH) and compared to monolayer parental cells (MON).
