Aim: To examine the relationship between pancreatic hyperechogenicity and risk factors for metabolic syndrome.
Methods: A general population-based survey of lifestyle-related diseases was conducted from 2005 to 2006 in Japan. The study involved 551 participants older than 40 year of age. Data for 472 non-diabetic adults were included in the analysis. The measures included the demographic factors, blood parameters, results of a 75 g oral glucose tolerance test, and abdominal ultrasonography. The echogenicity of the pancreas and liver was compared, and then the subjects were separated into two groups: cases with pancreatic hyperechogenicity ( = 208) and cases without (controls, = 264). The differences between both groups were compared using an unpaired -test or Fisher's exact test. Multiple logistic regression analysis was used to determine the relationship between the pancreatic hyperechogenicity and clinical and biochemical parameters.
Results: Subjects with pancreatic hyperechogenicity had decreased serum adiponectin concentration compared to control subjects [8.9 (6.5, 12.8) 11.1 (7.8, 15.9), < 0.001] and more frequently exhibited features of metabolic syndrome. Logistic regression analysis showed that the following variables were significantly and independently associated with pancreatic hyperechogenicity: Presence of hypoadiponectinemia, increased body mass index (BMI), higher homeostasis model assessment of insulin resistance (HOMA-IR) score, and presence of fatty liver. Similar associations were also observed in subjects with pancreatic hyperechogenicity without fatty liver. Multivariate association analysis of data from participants without fatty liver showed that hypoadiponectinemia was significantly associated with pancreatic hyperechogenicity (OR = 0.93, 95%CI: 0.90 - 0.97, < 0.001). This association was independent of other confounding variables. Additionally, an increased BMI and higher HOMA-IR score were significantly associated with pancreatic hyperechogenicity.
Conclusion: Pancreatic hyperechogenicity is independently associated with increased BMI, insulin resistance, and hypoadiponectinemia in the general population.

Abdominal fat necrosis in a female dromedary camel: Clinical, hematobiochemical, sonographic, and pathologic findings.

Article Synopsis
- - Abdominal fat necrosis in camels often appears incidentally during exams, presenting as hard masses; the differential diagnosis can include other serious conditions like tumors.
- - A 7-year-old female dromedary camel experienced weakness and weight loss, leading to various treatments that were ineffective until advanced diagnostic methods were used, revealing multiple masses and other abnormalities.
- - Transabdominal ultrasonography proved essential for identifying potential abdominal masses and facilitating biopsy, but histopathological analysis ultimately confirmed the diagnosis of abdominal fat necrosis and associated conditions.
Fetal hyperechogenic pancreas and gestational diabetes mellitus: a meta-analysis.

Introduction: Gestational diabetes mellitus is the most common metabolic disorder in pregnancy, and it is associated with detrimental short- and long-term consequences to both the fetus and the mother. Some studies in the literature have found an association between the identification of fetal hyperechogenic pancreas via prenatal ultrasound and the presence of gestational diabetes mellitus. The aim of our study was to assess the association of fetal hyperechogenic pancreas with gestational diabetes mellitus using the meta-analytic method.

Objective: To determine the frequency of nonalcoholic fatty pancreatic disease in patients with carcinoma pancreas presenting for upper abdominal endoscopic ultrasound.
Methods: The prospective cross-sectional study was conducted in the Endoscopy Suite of Surgical Unit 4, Civil Hospital, Karachi, from October 2019 to September 2020, and comprised patients presenting for endoscopic ultrasound. Patients were divided into Group A comprising carcinoma pancreas patients, and Group B having non-carcinoma pancreas patients.
