The formaldehyde (FA) is a universally used chemical for preservation of cadavers in dissection halls. The adverse effects of formalin exposure are health concern to faculty, workers, and students. The benefits of using formalin, its cost effectiveness, and its proper fixation and efficient preservation of tissue, have to outweigh its adverse effects on the health of those working with it. The best way to ensure the benefits outweigh the risks are providing adequate ventilation, using personal protective equipment, and developing awareness of FA’s adverse effects. This study observed that both government and private colleges had better ventilation when more windows and doors were present, but active ventilation strategies like powerful exhaust, along with monitoring of FA level (personal or dissection hall), were needed. Students exposed to FA suffered eye and nose mucosal irritation. But faculty and workers with prolonged exposure to FA had more severe respiratory symptoms and suffered migraines. Hence personal FA monitoring and personal protective equipment must be made mandatory for those with prolonged exposure to FA. In addition, proper ventilation should be in place to reduce formalin vapours levels in workspaces.

The exocrine part of the pancreas has a duct system called the pancreatic ductal system (PDS). Its mechanism of development is complex, and any reorganization during early embryogenesis can give rise to anatomical variants. The aim of this study is to collect, classify, and analyze published evidence on the importance of anatomical variants of the PDS, addressing gaps in our understanding of such variations. The MEDLINE, Web of Science, Embase, and Google Scholar databases were searched to identify publications relevant to this review. R studio with meta-package was used for data extraction, risk of bias estimation, and statistical analysis. A total of 64 studies out of 1,778 proved suitable for this review and metanalysis. The meta-analysis computed the prevalence of normal variants of the PDS (92% of 10,514 subjects). Type 3 variants and “descending” subtypes of the main pancreatic duct (MPD) predominated in the pooled samples. The mean lengths of the MPD and accessory pancreatic duct (APD) were 16.53 cm and 3.36 cm, respectively. The mean diameters of the MPD at the head and the APD were 3.43 mm and 1.69 mm, respectively. The APD was present in only 41% of samples, and the long type predominated. The pancreatic ductal anatomy is highly variable, and the incorrect identification of variants may be challenging for surgeons during ductal anastomosis with gut, failure to which may often cause ductal obstruction or pseudocysts formation.
