This study aims to investigate the clinical significance of preventing incision skin necrosis and the improved function offered in patients with a chronic Achilles tendon rupture treated surgically with a modified spoon-shaped medial incision. From January 2013 to January 2017, 50 patients (N = 50) who were admitted to our department with a clinically and radiologically confirmed chronic Achilles tendon rupture met inclusion criteria and were divided retrospectively into two groups. In group A (n = 26), a modified spoon-shaped medial incision in the surgical repair of Achilles tendon rupture was performed. In group B (n = 24), a traditional posterior medial incision was used. All skin healing was observed. Functional evaluation was performed using American Orthopedic Ankle & Foot Society scale(AOFAS) hindfoot score and Achilles tendon total rupture score(ATRS). Return-to-work time and major complications were also measured. The patients were followed for 12 to 48 months. All incisions exhibited primary healing in group A, while four incisions healed delay for skin necrosis which includes superficial, deeper necrosis, and skin defection caused by the necrosis in group B. Both groups had similar results regarding return-to-work time. There were no infections in either group. There was no rerupture of the Achilles tendon in either group. Patients in group A had better AOFAS hindfoot score (p = .020) and ATRS (p = .010), and the difference was significant (p ≤ .05).Using the modified spoon-shaped medial incision in the surgical repair of a chronic Achilles tendon rupture seems to be a safe and effective method that may reduce risk of incision skin necrosis and offers better function in patients with a chronic Achilles tendon rupture.The expense of creating exhaust ventilation in a gross anatomy laboratory can be an impediment to gross anatomical education, especially in locations with little availability of funds (e.g., developing countries). Thus, the need for inexpensive yet effective exhaust ventilation is important for gross anatomical education. This study details the creation of a downdraft ventilation table that cost less than 200 USD to build, was built with commonly available materials (i.e., lumber, tarps, rebar, corrugated steel, staples, and screws), was built by one person with little difficulty in a matter of hours, was relatively light weight (75.2kg fully-assembled), and was easy to transport. Further, the table was structurally sound and handled a load of at least 331kg without damage. The table was affixed to a simple local exhaust ventilation system that cost ∼300 USD and generated an exhaust flow of 3099m3/h from the table. The table was capable of removing all airborne formaldehyde (0.00ppm) despite a pool of 100% formalin placed 20.3cm above the table. Panobinostat in vitro Furthermore, the height of the table could easily be adapted for handicapped accessibility and for individuals who are shorter or taller than average. The downdraft system also has applications beyond the gross anatomy laboratory (e.g., exhaust ventilation for embalming, manufacturing, and clinical/surgical aerosol-generating procedures). This report represents a proof-of-concept a downdraft table that costs less than 200 USD can be built easily and paired effectively with an inexpensive local exhaust ventilation system at a total expense of approximately 500 USD. This report marks an improvement in gross anatomy laboratory safety and accessibility.
Pancreatic ductal adenocarcinoma can directly invade the peripancreatic lymph nodes; however, the significance of direct lymph node invasion is controversial, and it is currently classified as lymph node metastasis. This study aimed to identify the impact of direct invasion of peripancreatic lymph nodes on survival in patients with pancreatic ductal adenocarcinoma.

A total of 411 patients with resectable/borderline resectable pancreatic ductal adenocarcinoma who underwent pancreatic resection at two high-volume centers from 2006 to 2016 were evaluated retrospectively.

Sixty (14.6%) patients had direct invasion of the peripancreatic lymph nodes without isolated lymph node metastasis (N-direct group), 189 (46.0%) had isolated lymph node metastasis (N-met group), and 162 (39.4%) had neither direct invasion nor isolated metastasis (N0 group). There was no significant difference in median overall survival between the N-direct group (35.0 months) and the N0 group (45.6 month) (p=0.409), but survival was significantly longer in the N-direct compared with the N-met group (25.0 months) (p=0.003). Similarly, median disease-free survival was similar in the N-direct (21.0 months) and N0 groups (22.7 months) (p=0.151), but was significantly longer in the N-direct compared with the N-met group (14.0 months) (p<0.001). Multivariate analysis identified resectability, adjuvant chemotherapy, and isolated lymph node metastasis as independent predictors of overall survival. However, direct lymph node invasion was not a predictor of survival.

Direct invasion of the peripancreatic lymph nodes had no effect on survival in patients undergoing pancreatic resection for pancreatic ductal adenocarcinoma, and should therefore not be classified as lymph node metastasis.

Adenosquamous carcinoma of the pancreas (ASCP) is a rare histologic subtype of pancreatic carcinoma. The clinicopathologic characteristics and surgical outcomes of ASCP are poorly understood due to the rarity of this disease. Recently, promising clinical responses in patients with pancreatic cancer have been obtained for antibodies against programmed death-1/programmed death-ligand 1 (PD-1/PD-L1). This study investigated the prevalence of PD-L1 expression and surgical outcomes of 56 ASCPs compared to 100 pancreatic ductal adenocarcinomas (PDACs).

A total of 56 resected cases of ASCPs were retrospectively reviewed; after matching for the T category, 100 PDACs were selected as a control group for comparison. Immunohistochemistry for p53, Smad4, and PD-L1 was performed in both groups.

The ASCPs exhibited distinct clinicopathologic features, such as larger tumour, location in the distal pancreas, frequent vascular invasion and distant metastasis. In survival analysis, 1-and 2-year overall survival (OS) rates were 51.
