A Short-Term Medical Mission in Rural Nepal: Chief Complaints, Medications Dispensed, and Unmet Health Needs.

Background Although Nepal is striving to expand primary health services for its citizens, many remote areas have limited access to basic health care. Short-term medical missions (STMMs) are one way of supplementing human resources for health in underserved areas. This article describes the chief complaints, medications dispensed, and unmet health needs during an STMM in rural Nepal. Methods This study is a retrospective analysis of data collected during an STMM that occurred in October 2017. Deidentified data from clinic intake forms were entered into an Excel spreadsheet, and formatted and cleaned. Demographics, chief complaints, medications, and unmet health needs were analyzed using descriptive statistics. Results During a two-day health camp, 443 patients were seen. The most common chief complaint was dental (33.4%) followed by musculoskeletal (28.2%) and gastrointestinal (21.2%). Medications were dispensed to 94.8% of patients, primarily analgesics, antibiotics, and ophthalmologic preparations. Of the patients, 21% had unmet health needs, including specialty care and labs or imaging that were beyond the scope of the STMM. One patient was referred urgently to a hospital for treatment of dyspnea and markedly elevated blood pressure. Conclusion While STMMs cannot replace access to primary health services, they can provide insight into acute care needs in a system that has limited surveillance. This information describing an acute care patient population should inform future development work.

Precise Characterization and 3-Dimensional Reconstruction of the Autonomic Nerve Distribution of the Human Ureter.

PURPOSE: We sought to characterize and 3-dimensionally reconstruct the distribution of the autonomic innervation of the human ureter. MATERIALS AND METHODS: Three male and 3 female pairs of ureters were evaluated at 2 mm serial transverse sections along the entire length of the ureter. The location of nerve tissue was immunohistochemically identified using the neuronal marker, S100 protein. ImageJ software was used to calculate nerve count and density in the adventitia and smooth muscle. Blender® graphics software was used to create a 3-dimensional reconstruction of autonomic nerve distribution. RESULTS: Within the adventitia nerve density was highest in the mid and distal ureter (females 2.87 and 2.71 nerves per mm2, and males 1.68 and 1.69 nerves per mm2) relative to the proximal ureter (females and males 1.94 and 1.22 nerves per mm2, respectively, p >0.0005). Females had significantly higher nerve density throughout the adventitia, especially in the distal ureter (2.87 vs 1.68 nerves per mm2, p <0.0005). In smooth muscle the nerve density progressively increased from the proximal to the distal ureter (p >0.0005). Smooth muscle nerve density was similar in the 2 genders (p = 0.928). However, in females nerve density was significantly higher in the first 2 cm of the distal ureter relative to the second 2 cm (3.6 vs 1.5 nerves per mm2, p <0.001) but not in males (3.0 vs 2.1 nerves per mm2, p = 0.126). CONCLUSIONS: Nerve density was highly concentrated at the distal ureter in the adventitia and smooth muscle of the male and female human ureters. The female ureter had greater nerve density in the adventitia, and in smooth muscle nerves were significantly concentrated at the ureteral orifice and the ureteral tunnel.

Redefining the Autonomic Nerve Distribution of the Bladder Using 3-Dimensional Image Reconstruction.

PURPOSE: We sought to create a 3-dimensional reconstruction of the autonomic nervous tissue innervating the bladder using male and female cadaver histopathology. MATERIALS AND METHODS: We obtained bladder tissue from a male and a female cadaver. Axial cross sections of the bladder were generated at 3 to 5 mm intervals and stained with S100 protein. We recorded the distance between autonomic nerves and bladder mucosa. We manually demarcated nerve tracings using ImageScope software (Aperio, Vista, California), which we imported into Blender™ graphics software to generate 3-dimensional reconstructions of autonomic nerve anatomy. RESULTS: Mean nerve density ranged from 0.099 to 0.602 and 0.012 to 0.383 nerves per mm2 in female and male slides, respectively. The highest concentrations of autonomic innervation were located in the posterior aspect of the bladder neck in the female specimen and in the posterior region of the prostatic urethra in the male specimen. Nerve density at all levels of the proximal urethra and bladder neck was significantly higher in posterior vs anterior regions in female specimens (0.957 vs 0.169 nerves per mm2, p<0.001) and male specimens (0.509 vs 0.206 nerves per mm2, p=0.04). CONCLUSIONS: Novel 3-dimensional reconstruction of the bladder is feasible and may help redefine our understanding of human bladder innervation. Autonomic innervation of the bladder is highly focused in the posterior aspect of the proximal urethra and bladder neck in male and female bladders.
