Diffuse idiopathic skeletal hyperostosis (DISH) is a relatively common progressive noninflammatory entheses disease. Patients are often asymptomatic or are undiagnosed due to minor chronic symptoms. We herein report a rare case in which the primary symptom was sudden-onset upper airway obstruction due to exuberant osteophytosis in the cervical spine. Treatment was successful with careful airway management and surgical osteophyectomy. Most DISH cases in the literature with airway obstruction have been managed with tracheotomy. However, the safety and necessity of this approach remain questionable. We herein discuss the possibility of conservative management as a choice of airway control. Airway obstruction due to DISH may be underrecognized. This highlights the importance of including DISH in the differential diagnosis of airway obstruction. In addition, a detailed evaluation and personalized care for each individual case is essential.

Thiodan (33.7% endosulfan), a polychlorinated cyclodiene insecticide, was evaluated for its histopathological effects on mosquitofish, Gambusia affinis, by light microscopy. Fish were exposed to doses of 0.00 (control), 1.00, 2.50, and 5.00 microg/L on days 7, 14, 21, and 30. No histopathological effects were apparent at control group. The histopathological alterations were characterized as oedema, degeneration, accumulation of lymphocytes in the lamina propria, disintegration of villuses, pycnotic state of nuclei, and necrosis in gut; degeneration, hypertrophy, sinusoids enlargement, hemorrhage, pycnosis position of nuclei, vacuolization of cell cytoplasm, infiltration of mononuclear lymphocyte, and congestion in liver. These alterations were time- and dose-dependent.

Pancreatic cysts include a variety of benign, premalignant, and malignant lesions. Endometrial cysts in the pancreas are extremely rare lesions that are difficult to diagnose before surgery. We report the case of a 26-year-old patient with a recent episode of left abdominal pain who presented with a large cyst in the pancreatic body. Laboratory results showed white blood cell and C-reactive protein elevation, whereas the patient's tumor marker levels were within the normal range. Distal pancreatectomy with splenectomy was performed. The final histopathological examination confirmed the presence of endometriotic cysts within the pancreas. Only 13 cases of endometriotic cysts of the pancreas have been previously reported. The preoperative diagnosis is challenging, and most patients undergo pancreatic resection because of suspected neoplasms. This case report reviews previous studies and discusses the clinicopathological features, pathogenesis, and appropriate treatment for pancreatic endometrial cysts.
