Abstract Background The guidelines recommend pancreatic resection for grade III and IV pancreatic injuries. On the other hand, organ preservation is an important issue. Herein, we present the first case of pancreatic injury with major pancreatic duct (MPD) disruption that was treated with the combination of preoperative placement of endoscopic nasopancreatic drainage (ENPD) catheter and pancreas preservation surgery after endoscopic pancreatic stenting (EPS) failure. Case presentation A 70-year-old female diagnosed with pancreatic injury was admitted to our hospital. She was hemodynamically stable. ERP revealed MPD disruption, and EPS failed. An ENPD catheter was placed preoperatively at the site of injury. During laparotomy, we identified a partial-thickness laceration in the pancreatic body. At the site of injury, the tip of the ENPD catheter was found; therefore, the patient was diagnosed with grade III pancreatic body injury with MPD disruption. The extent of crush was not severe, and we had no difficulty in identifying the distal MPD segment. We inserted the ENPD catheter into the distal MPD segment. The ruptured MPD and the laceration was sutured, then pancreatic resection was prevented. She was discharged on POD 56. Conclusion The treatment strategy incorporated ERP, placement of an ENPD catheter preoperatively, and a simple surgery in a hemodynamically stable patient with pancreatic injury allows the pancreas and spleen to be preserved.

Abstract Background To describe the inter-ethnic variation in medial orbital wall anatomy between Chinese, Malay, Indian and Caucasian subjects. Methods Single-centre, retrospective, Computed Tomography (CT)-based observational study. 20 subjects of each ethnicity, were matched for gender and laterality. We excluded subjects younger than 16 years and those with orbital pathology. OsiriX version 8.5.1 (Pixmeo., Switzerland) and DICOM image viewing software CARESTREAM Vue PACS (Carestream Health Inc., USA) were used to measure the ethmoidal sinus length, width and volume, medial orbital wall and floor angle and the relative position of the posterior ethmoid sinus to the posterior maxillary wall. Statistical analyses were performed using Statistical Package for Social Sciences version 25.0 (IBM, USA). Results There were 12 males (60 %) in each group, with no significant difference in age (p = 0.334–0.994). The mean ethmoid sinus length in Chinese, Malay, Indian and Caucasian subjects, using the Chinese as reference, were 37.2, 36.9, 38.0 and 37.4mm, the mean width was 11.6, 10.5, 11.4 and 10.0mm (p = 0.020) and the mean ethmoid sinus volume were 3362, 3652, 3349 and 3898mm3 respectively. The mean medial orbital wall and floor angle was 135.0, 131.4, 131.0 and 136.8 degrees and the mean relative position of posterior ethmoid sinus to posterior maxillary wall were − 2.0, -0.2, -1.5 and 1.6mm (p = 0.003) respectively. Conclusions No inter-ethnic variation was found in decompressible ethmoid sinus volume. Caucasians had their posterior maxillary sinus wall anterior to their posterior ethmoidal walls unlike the Chinese, Malay and Indians. Awareness of ethnic variation is essential for safe orbital decompression.

Abstract Objectives The aim of this study was to investigate the role of CD68 (+) histiocytic macrophages (H-M) in the nasal polyp pathogenesis. Materials and Methods The study group consisted of 24 adult patients with nasal polyposis. The control group consisted of 11 adult patients without nasal polyps. A total of 36 nasal polyp samples (10-nasal cavity, 10-maxillary sinus, and 16-ethmoid sinus) from the study group and 11 inferior turbinate samples from the control group were analyzed by immunohistochemical staining, with monoclonal antibodies against CD68 (+) H-M. Results CD68 positivity was significantly higher than the control group in the subepithelial (SE) layer of the ethmoid sinus, and deep layers of nasal cavity, maxillary, and ethmoid sinuses. In SE and deep layers of ethmoid and maxillary sinuses, CD68 positivity was significantly higher than that of the epithelial layer. In the deep layer, histiocytic macrophages tended to gather around eosinophils. Conclusion The high numbers of CD68 (+) histiocytic macrophages mainly located in deep layer of lamina propria may be responsible for the phagocytosis of eosinophils within the polyp tissue. Therefore, it may be concluded that increased macrophages in nasal polyps do not trigger the growth of nasal polyps. Instead, they may serve to reduce the number of eosinophils in already-developed nasal polyps.

Penetrating transorbital injury with skull base involvement is a rare occurrence from a crayon. We report a case of a 2-year-old male who sustained a penetrating crayon injury through the right orbit and lamina papyracea into the posterior ethmoid sinus complicated by cerebrospinal fluid leak. There have been no other reported cases of this type of injury by a crayon.
