Article Synopsis
  • The study aimed to evaluate the prevalence of pancreatic steatosis (PS) using transabdominal ultrasonography in Turkish gastroenterology clinics and identify associated factors.
  • A total of 1,700 volunteers revealed a PS prevalence of 68.9%, with factors like age, BMI, and metabolic syndrome linked to its severity.
  • The study also found that 11.8% of PS cases were in lean individuals, who were generally younger and had lower metabolic risk factors compared to those with non-lean PS.

Background/aims: Chronic constipation is an important public health problem and significantly affects women's lives. It is important to investigate nonpharmacological applications that can be used in the treatment of chronic constipation. The aim is to assess how abdominal massage and Kinesio taping impact constipation severity, quality of life (QOL), and perception of subjective improvement in women with chronic constipation.

Article Synopsis
  • Acute pancreatitis (AP) is a leading gastrointestinal condition causing hospitalization, with a focus on evaluating its clinical features and adherence to international management guidelines.
  • The study analyzed 2,144 hospitalized AP patients in Turkey, finding that most cases were mild, with biliary causes being the most common, and an overall mortality rate of 1.6%.
  • Results indicate good predictive accuracy for severe cases using specific scoring systems, but show inconsistent adherence to treatment guidelines, particularly in administering prophylactic measures like NSAIDs and antibiotics.

The reference evapotranspiration (ETo) is considered one of the primary variables for water resource management, irrigation practices, agricultural and hydro-meteorological studies, and modeling different hydrological processes. Therefore, an accurate prediction of ETo is essential. A large number of empirical methods have been developed by numerous scientists and specialists worldwide to estimate ETo from different climatic variables.

Reference evapotranspiration (ETo) is essential for irrigation practices and the management of water resources and plays a vital role in agricultural and hydro-meteorological studies. The FAO-56 Penman-Monteith (PM) equation, recommended as the sole standard method of calculating ETo by the Food and Agriculture Organization of the United Nations (FAO), is the most commonly used and accurate model to determine the ETo and evaluate ETo equations. However, it requires many meteorological variables, often restricting its applicability in regions with poor or missing meteorological observations.

Vitamin A has an essential role in the maintenance of corneal and conjunctival epithelization, as well as photoreceptor transduction in the retina. A deficiency of vitamin A causes keratinization of the surface epithelium, and night blindness is often the first symptom. This report describes a case of chronic intestinal pseudo-obstruction (CIPO), a rare and potentially fatal disease, diagnosed following detection of a vitamin A deficiency in an ophthalmological examination.

Background/aims: Glycoprotein 2 (GP2), the major autoantigen of Crohn's disease (CD)-specific pancreatic autoantibodies, is reportedly correlated with several characteristics of CD. We investigated this serological marker in Turkish patients with CD and assessed its utility in combination with anti-Saccharomyces cerevisiae antibodies (ASCAs) for differential diagnosis of CD.

Materials And Methods: A total of 60 patients with CD, 62 patients with ulcerative colitis (UC), and 46 healthy controls with a definite diagnosis who were similar in age and sex were enrolled in the study conducted from November 2011 to October 2012.

Background/aims: Colorectal laterally spreading tumors are superficial tumors classified into two groups as granular (G-laterally spreading tumor) and non-granular (non-granular-laterally spreading tumor) types. In this study, we aimed to investigate the efficacy and feasibility of endoscopic submucosal dissection in the treatment of laterally spreading tumors.

Materials And Methods: Forty-four laterally spreading tumors in 40 patients were treated with endoscopic submucosal dissection at a tertiary referral hospital.

In sexually reproducing organisms, primordial germ cells (PGCs) give rise to the cells of the germ line, the gametes. In many animals, PGCs are set apart from somatic cells early during embryogenesis. This study explores the origin of primordial germ cells (PGCs) of the zebra fish and examines their morphology during early development (1st day-15th day).

Aim: To investigate the indication, feasibility, safety, and clinical utility of endoscopic submucosal dissection (ESD) in the management of various gastrointestinal pathologies.

Methods: The medical records of 60 consecutive patients (34 female, 26 male) who underwent ESD at the gastroenterology department of Kocaeli University from 2006-2010 were examined. Patients selected for ESD had premalignant lesions or non-invasive early cancers of the gastrointestinal tract and had endoscopic and histological diagnoses.
