Exploring the clinical characteristics and prevalence of the annular pancreas: a meta-analysis.

BACKGROUND: The annular pancreas (AP) is a rare gastrointestinal congenital malformation, in which malrotation of the pancreatic ventral bud in the seventh week of embryonic development manifests in a partial or complete ring of tissue around the second part of the duodenum. METHODS: The main online medical databases such as PubMed, ScienceDirect, Wiley online library, Web of Science, and EBSCO discovery service were used to gather all relevant studies on the AP. RESULTS: A total of 12,729,118 patients were analyzed in relation to the prevalence of AP. The pooled prevalence of AP was 0.0045% (95% CI: 0.0021%-0.0077%). The most frequent comorbidity in adults and children was duodenal obstruction, with a pooled prevalence of 24.04% and 52.58%, respectively (95% CI: 6.86%-46.48% and 35.56%-69.31%, respectively). The most frequent operation in adult patients with AP was duodenojejunostomy, with pooled prevalence established at 3.62% (95% CI: 0.00%-10.74%). CONCLUSION: The diagnostic complexity of AP is accentuated by its nonspecific clinical symptoms, making accurate identification reliant on imaging studies. Therefore, having a thorough knowledge of the clinical characteristics of the AP and its associated anomalies becomes paramount when faced with this rare congenital condition.

The Morphology of the Pituitary Gland: A Meta-Analysis with Implications for Diagnostic Imaging.

The objective of this meta-analysis was to present transparent data on the morphology of the pituitary gland (PG) using the available data in the literature. The main online medical databases, such as PubMed, Embase, Scopus, and Web of Science, were searched to gather all relevant studies regarding PG morphology. The mean overall volume of the PG was found to be 597.23 mm3 (SE = 28.81). The mean overall height of the PG was established to be 5.64 mm (SE = 0.11). The mean overall length of the PG was found to be 9.98 mm (SE = 0.26). In the present study, the PG's overall morphology and morphometric features were analyzed. Our results showed that, on average, females from Asia have the highest volume of PG (706.69 mm3), and males from Europe have the lowest (456.42 mm3). These values are crucial to be aware of because they represent the normal average properties of the PG, which may be used as reference points when trying to diagnose potential pathologies of this gland. Furthermore, the present study's results prove how the PG's size decreases with age. The results of the present study may be helpful for physicians, especially surgeons, performing procedures on the PG.

Treatment Options for Tennis Elbow - An Umbrella Review.

INTRODUCTION: The main goal of the present umbrella review was to provide the most up-to- date and evidence-based results regarding the various treatment options for tennis elbow (TE), which hopefully will significantly decrease the confusions existing in the literature. Furthermore, our study differs from past analytical studies because, as to the best of the authors' knowledge, is the first to provide independent (not in comparison to other treatment) statistical results regarding the effectiveness of each TE treatment. MATERIALS AND METHODS: Major medical databases such as PubMed, Scopus, Embase, Web of Science, Google Scholar, Cochrane Library, BIOSIS, and EBSCO were searched. The overall search process was conducted in 3 stages. RESULTS: A total of 40 studies met the inclusion criteria and were included in this study. Out of those 40 meta-analyses, a total of 160 primary studies were screened in order to extract the data and perform a statistical analysis. CONCLUSION: The present umbrella review underlines the efficiency of injection therapies, especially autologous blood, and platelet-rich plasma, while simultaneously proving the ineffectiveness of acupuncture and shock wave therapy as treatments for TE. Furthermore, the value of other known conservative treatment modalities, such as physical therapy, has been demonstrated.
