Article Abstract
Endoscopical and histological features of oesophagogastroduodenal zone, parameters of pH-metry and electrogastroenterography, qualitative and quantitative characteristics of microbiocenosis were studied in 80 female persons with postcholecystectomy syndrome more then a year after cholecystectomy. In the presence of duodenogastral reflux the most natural is the combination of distal oesophagitis, antral atrophic gastritis and duodenitis, accompanied with low level of gastric acidity, gastric hypokinesis and duodenal dyskinesis, dysbacteriosis of mucosal microflora with its quantitative increase and appearance of bacteria with expressed pathogenicity non-typical for this biotope. These data should be taken into consideration for determination of pre- and postoperative treatment tactics for patients with gallstones.

Carcinosarcoma of the breast: Facing the challenge of a rare nosologic entity.
World J Clin Cases

Department of Surgery, National and Kapodistrian University of Athens, Athens 11527, Greece.
Carcinosarcoma (CS), also known as metaplastic breast carcinoma with mesenchymal differentiation, is one of the five distinct subtypes of metaplastic breast cancer. It is considered as a mixed, biphasic neoplasm consisting of a carcinomatous component combined with a malignant nonepithelial element of mesenchymal origin without an intermediate transition zone. Although cellular origin of this neoplasm remains controversial, most researchers declare that neoplastic cells derive from a cellular structure with potential biphasic differentiation.

Purpose: This study investigated epidemiologic features of patients with pancreatic cancer in Korea, according to the histologic subtypes.
Methods: The Korea Central Cancer Registry data on patients with pancreatic cancer from 1999 to 2019 were reviewed. The 101,446 patients with pancreatic cancer (C25 based on the International Classification of Diseases, 10th revision) were allocated according to the following morphological codes: A, endocrine; B, carcinoma excluding cystic and mucinous; C, cystic or mucinous; D, acinar cell; and E, sarcoma and soft tissue tumor.
Intranodular and perinodular ultrasound radiomics distinguishes benign and malignant thyroid nodules: a multicenter study.
Gland Surg

Department of Radiology, Ordos Central Hospital, Ordos, China.
Background: Ultrasound based radiomics prediction model can improve the differentiation ability of benign and malignant thyroid nodules to avoid overtreatment. This study evaluates the role of predictive models based on intranodular and perinodular ultrasound radiomics in distinguishing between benign and malignant thyroid nodules.
Methods: A total of 1,076 thyroid nodules were enrolled from three hospitals between 2016 and 2022, forming the training, validation and test cohorts.

Polycystic ovarian syndrome (PCOS) is a complex endocrine-metabolic disorder, and multiple factors contribute to its pathophysiology. The current study assessed a PCOS-like animal model induced by consuming a high-fat sugar (HFHS) diet and compared the treatment outcome of mitochondrial-targeted antioxidants versus heat therapy. Sixty rats were divided into the following study groups: three control groups (negative and positive for the treatments used), HFHS, hot tub therapy (HTT) treatment, and MitoQ10 treatment (500 µmol/L MitoQ10 in clean drinking water daily, from week fourteen till week twenty-two of the study).

Embryonic mammary gland development unfolds with the specification of bilateral mammary lines, thereafter progressing through placode, bud, and sprout stages before branching morphogenesis. Extensive epithelial-mesenchymal interactions guide morphogenesis from embryogenesis to adulthood. Two distinct mesenchymal tissues are involved, the primary mammary mesenchyme that harbors mammary inductive capacity, and the secondary mesenchyme, the precursor of the adult stroma.
