Osteoporosis is a worldwide problem and it mainly affects postmenopausal women. Osteoporosis associated with pregnancy or lactation is a rare condition. The incidence and mechanism of this phenomenon has not been clarified, but it can cause one or more vertebral compression fractures with severe, prolonged back pain in the affected women. We experienced this uncommon case, treated it with percutaneous vertebroplasty. A 35-old-woman visited our hospital with complaints of severe back pain and flank pain 2 months after normal vaginal delivery. She was diagnosed with osteoporotic vertebral compression fractures on the T5, 8, 9 and 11 vertebral bodies and we performed percutaneous vertebroplasty on the T8, 9 and 11 vertebrae with a good result. We present here an unusual case of pregnancy-associated compression fractures treated by percutaneous vertebroplasty.

STUDY OBJECTIVE: determine the level of medical care required for mass gatherings and describe the types of medical problems encountered in a religious mass gathered ceremony. DESIGN: Standard charts and a four-tiered triage system(minor, moderate, urgent, and emergent) were developed before the event. The triage system was applied to each chart retrospectively by a single emergency physician. SETTING: Medical staff(10 physicians,13 nurses,1 pharmacist, and 54 first-aid attendants) were based in 8 advanced life support (ALS) clinics. INTERVENTIONS: First-aid attendants referred patients to the clinics, where nurses conducted initial assessments and referred patients to physicians at the venue. Three ambulances were stationed at the venues. RESULT: 22 trauma patients were developed and 183 medical complaints were encountered. Only 7 urgent medical problems were encountered.

Osteoporotic patients who undergo percutaneous vertebroplasty (PVP) have the risk of a repeated collapse of their adjacent vertebral body due to alteration of load transfer into the adjacent vertebral body. The authors have experienced a rare case of repeated osteoporotic vertebral compression fractures (VCF) resulting in extreme multi-level PVP. A 74-year-old female developed severe back pain after slipping down one month ago. Her X-ray and MR images indicated a T11 VCF. She underwent successful PVP with polymethylmethacrylate (PMMA). Two weeks later, she returned to our hospital due to a similar back pain. Repeated X-ray and MR images showed an adjacent VCF on T12. A retrial of PVP was performed on T12, which provided immediate pain relief. Since then, repeated collapses of the vertebral body occurred 12 times in 13 levels within a 24-month period. Each time the woman was admitted to our hospital, she was diagnosed of newly developed VCFs and underwent repeated PVPs with PMMA, which finally eased back pain. Based on our experience with this patient, repeated multiple PVP is not dangerous because its few and minor complications. Therefore, repeated PVP can serve as an effective treatment modality for extreme-multi level VCFs.

A retrospective analysis of 122 consecutive of rhegmatogenous retinal detatchment cases which obtained successful surgical results was performed. All the cases were followed for longer than 1 year postoperatively. 15 eyes (12.3%) developed macular pucker. There was no significant difference in sex distribution and mean age was 43.7 years. The mean lapse time between surgery and the development of macular pucker was 7.2 months. Significant factors for developing macular pucker were multiple operation, preoperative macular detachment, and duration of retinal detachment (longer than 1 month). Other factors such as subretirial fluid drainage and myopia were not significant. 9 of 15 eyes with macular pucker were treated with vitrectomy and visual acuity improved in 66.7% of surgically treated eyes. These results suggest that success with single surgical procedure, operation before macular detachment, and early treatment of retinal detachment are important for preventing postsurgical macular pucker.

Exocrine glands secrete large volumes of fluid in response to neural or hormonal stimulation. In the present studies, we examined the immunolocalization of AQP1-5 in salivary glands of rat to clarify the potential roles of these for fluid secretion. Immunohistochemistry using cryosections of rat submandibular glands revealed that AQP1 was located in the capillary endothelia between secretory gland cells. Secretory gland cells and ductal cells were not labeled with anti-AQP1, AQP2 and AQP3 were not present in either salivary gland cells, intercalated ductal cells or striated ducts. AQP4 was localized in the basolateral plasma membrane domains of the intercalated ductal cells in rat submandibular glands whereas either secretory gland cells or striated ducts were not labeled. AQP5 was abundant in the apical domains of the secretory gland cells as well as of the secretory canaliculi and intercalated ductal cells, consistent with RT-PCR analyses as well as previous data (Nielsen et al., 1997). Importantly, AQP5 labeling was associated with the apical part of the secretory gland cells, raising the possibility for trafficking of AQP5 from intracellular vesicles to the apical plasma membranes following neuronal or hormonal stimulation. In parotid and sublingual glands, the immunolabeling pattern of AQPs was identical with that seen in submandibular glands, while the AQP5 immunolabeling was sparse in the sublingual glands which is mainly composed of mucinous glands. In conclusion, the basolateral localization of AQP4 in the intercalated ductal cells and presence of AQP5 in the apical plasma membrane of secretory acinar cells, canaliculi and intercalated ductal cells of submandibular gland suggest that both AQP4 and AQP5 may provide a critical pathway for osmotic water flow into the secreted fluid.

Objective: To assess the safety and efficacy of lymphopseudoaneurysm (LPA) glue (n-butyl cyanoacrylate [NBCA]) embolization in the management of chylous ascites after retroperitoneal surgery. Materials and Methods: A retrospective analysis from January 2014 to October 2018 was performed in six patients (4 females and 2 males; mean age, 45.3 ± 14.2 years; range, 26–61 years) who underwent LPA embolization for chylous ascites developing after retroperitoneal surgery involving the perirenal space (four donor nephrectomies, one partial nephrectomy, and one retroperitoneal lymphadenectomy). After placing a percutaneous drainage catheter into the LPA or adjacent lymphocele, embolization was performed by filling the LPA itself with a mixture of glue and Lipiodol (Guerbet). Results: Daily drainage from percutaneously placed drains exceeded 300 mL/day despite medical and surgical treatment (volume: mean, 1173 ± 1098 mL; range, 305–2800 mL). Intranodal lymphangiography was performed in four of the six patients and revealed leakage in 2 patients. Percutaneous embolization of the LPA was successful in all patients using an NBCA and Lipiodol mixture in a ratio of 1:1–1:2 (volume: mean, 4.3 ± 1.1 mL; range, 3–6 mL). Chylous ascites was resolved and the drainage catheter was removed in all patients within 4 days after the procedure (mean, 2.0 ± 1.8 days; range, 0–4 days). No procedure-related complications or recurrence of chylous ascites occurred during a mean follow-up period of 37.3 months (range, 21.1–48.4 months). Conclusion Glue embolization of LPA has the potential to be a feasible and effective treatment method for the management of chylous ascites after retroperitoneal surgery.

Uni- or bilateral mandibular hypoplasia can be associated with various syndromes or is acquired after early traumatic or inflammatory disease in the temporomandibular joint(TMJ). Early treatment is necessary to avoid consequent impairment of midfacial growth. The standard treatment of these malformations consists of the application of bone grafts which can lead to unpredictable growth, but the new procedure of bone lengthening which was presented by McCarthy et al. represents a limited surgical intervention and therefore open up a new perspective of treatment, especially in younger children with severe deformities. Patients with hemifacial microsomia and facial asymmetry have a vertically short maxilla, a tilted occlusal plane, and a short mandible. A 14-years-old boy with facial asymmetry, who was fractured on both condyle and mandibular symphysis before 8 years ago, was treated by mandibular ramus lengthening, symphysial widening and surgically assisted rapid palatal expansion with corticotomy. After allowing 1 week for the healing of the periosteum, the distraction was performed at the rate of 0.5-1.0mm per day for 7 days on maxilla and 14 days on mandible. The device was maintained on maxilla and mandible for 12 weeks following distraction. The difference in ramus and mandibular transverse deficiency were corrected and facial asymmetry was improved with complex distraction osteogenesis.

Two patients underwent anesthesia for pheochromocytoma involving adrenal gland and extra- adrenal space. Patient 1 was not diagnosed as pheochromocytoma before surgery and thus proper preoperative evaluation and care was not possible. During surgery and anesthesia, the patient showed a marked blood pressure variation, arrythmia and tachycardia. Pulmonary edema occurred intraoperatively, but subsided with positive end expiratory pressure and the use of diuretics and morphine. Patient 2 was preoperatively diagnosed as pheochromocytoma and was thus given prazosin and nifedipine (for 11 days) preoperatively. Blood pressure and pulse rate throughout the surgery and anesthesia were stable and no intra- and postoperative complication occured. We believe that careful preoperative preparation is essential to minimize intraoperative hemo- dynamic disturbance and their sequelae.
