Background/aims: There are few large sample, single-center series that focus on the methods of diagnosis, treatment and long-term survival of patients with Pancreatic neuroendocrine neoplasms (pNENs).
Methodology: Forty-seven patients with pNENs treated at Anhui province hospital affliated of Anhui Medical University during January 2002 to December 2013 were analyzed retrospectively. Clinical data were collected and statistically analyzed.
Results: The sensitivity of abdominal ultrasound, CT and MRI was 71.2% (28/39), 92.3% (38/41), and 75% (6/8), respectively. All patients received operation. 46 underwent radical surgery, pancreatic fistula in 9 patients, seroperitoneum in 4 patients, incisional infection in 4 patients. The cases of grade G1, G2, and G3 were 22, 19, and 6, respectively. The cases of stage I, II, III and IV were 32, 11, 4, and 0, respectively. The overall 1-, 3, and 5-year survival rates were 94.9%, 88.4%, and 84.4%. Univariate analysis showed that TNM, WHO classification, lymph nodes metastasis, vascular and neural invasion were risk factors of pNENs.
Conclusion: Sprial CT was an optimal diagnostic method, while surgery was the first choice for treatment. Surgical resection in pNENs results in long-term survival. TNM, WHO classification, lymphatic metastasis, vascular and neural invasion were closely related to the prognosis of pNENs.

Accurate and timely diagnosis of t(9;22)-positive leukemias is vital to improving survival in pediatric patients. In low-resource settings, where healthcare disparities are exacerbated by limited resources, cost-effective and efficient diagnostic methods are essential for bridging these gaps and ensuring better outcomes. Among the diagnostic tools evaluated among 23 patients sample, RT-PCR demonstrated superior sensitivity (100%) and the shortest turnaround time (7 days), significantly outperforming FISH and karyotyping in both accuracy and timeliness.

Prolactinomas are the most common hormone-secreting pituitary adenomas in adolescents. Dopamine agonists (DA) are used as first-line medical treatment. DAs are associated with an array of physical side effects; however, impulse control disorders (ICDs), such as pathological gambling (PG), have also been reported in adults.

The tRNA-derived small RNAs (tsRNAs) are a new class of non coding RNAs, which are stable in body fluids and can be used as potential biomarkers for disease diagnosis. However, the exact value of tsRNAs in the diagnosis of tuberculosis (TB) is still unclear. The objective of the present study was to evaluate the performance of the serum tsRNAs biosignature to distinguish between active TB, healthy controls, latent TB infection, and other respiratory diseases.

Introduction: Excision and primary anastomosis (EPA) urethroplasty is the standard treatment for traumatic urethral strictures, but managing them remains challenging for urologists. Identifying factors leading to EPA urethroplasty failure benefits both patients and surgeons. This study aims to analyze risk factors for urethral stricture recurrence after one-year follow-up of EPA urethroplasty.
