The incidence of contrast media extravasation has been increasing gradually. Most contrast media extravasations only can cause pain, swelling and erythema. However, in more severe cases, skin necrosis, ulceration, or compartment syndrome may occur, often necessitating a surgery. Early diagnosis and treatment should be established on the spot in order to avoid such a severe damage. We present a case of 42-year-old woman with a compartment syndrome in the right upper extremity caused by extravasation of computed tomography contrast media.

PURPOSE: There has been a scarcity of integrated, long-term (>4 week) studies on structural and functional alterations in the penis according to the period following cavernous nerve (CN) injury. The aim of this study was to investigate time-dependent structural and functional changes in the corpus cavernosum following CN injury in a rat model. MATERIALS AND METHODS: Ninety male Sprague-Dawley rats (10 weeks old) were divided into 4 groups: normal control (C), sham (S), bilateral CN resection (R), and bilateral CN crush injury (I) groups. At 1, 4, and 12 weeks after the procedure, erectile function was assessed by electrostimulation. The terminal deoxynucleotidyl transferase-mediated 2'-deoxyuridine 5'-triphosphate nick end labeling (TUNEL) assay was performed for detection of apoptosis. Masson's trichrome staining and immunohistochemistry were performed for detection of alpha smooth muscle actin (alpha-SMA). Western blot analysis was then performed. RESULTS: The R and I groups showed persistent impairment of erectile function at all three points in time. Apoptosis peaked at 1 week after resection or crush injury and then gradually subsided. The smooth muscle cell/collagen ratio and expression of alpha-SMA gradually decreased over time after CN resection or crush injury. Myosin phosphatase target subunit 1 phosphorylation progressively increased over time after CN resection or crush injury. On the other hand, expression of phospho-protein kinase B, phospho-endothelial nitric oxide synthase, and neuronal nitric oxide synthase transiently decreased at 1 week after resection or crush injury and then recovered to the control values. CONCLUSIONS: Our results suggest that persistent up-regulation of the RhoA/Rho-kinase pathway and structural change such as decreased smooth muscle cell and increased cavernosal fibrosis might play an important role in persistent erectile dysfunction following CN injury.

The diagnostic possibility and the incidence of ectopic pregnancy are increasing due to several factor. Furthermore, radioimmunoassay of serum β-HCG and US make it possible to diagnose early before the tubal rupture. A conventional surgical approach has been considered as a choice of treatments. Until recent years, however, surgery may have considerable risk of infertility and sugical hazard. In view of the natural tendency of some ectopic pregnancies to terminate in tubal abortion or complete resorption, we tried to cure ectopic pregnancy with nonsurgical transcervical intervention. Five of 8 patients with unruptured tubal pregnancies, it was possible to inject PGF2a into the tubes or gestational sac. 4 of them were ended up with satisfactory reduction of serum β-HCG level and improvement of symptoms & signs. In only one patient, β-HCG level remained a high level continuously, so salpingectomy was done. As a result, we consider that fluoroscopy-guided transcervical interventional procedure is a useful treatment modality for early unruptured ectopic pregnancy.

Nontraumatic cerebrospinal fluid rhinorrhea is a very rare disease that comprises 3-4% of all CSF rhinorrhea cases. The principle treatment for CSF rhinorrhea is surgery because more conservative treatments usually fail. The authors executed extracranial repair of the fistula and sphenoid sinus obliteration with abdominal fat in a 33-year old male diagnosed with nontraumatic CSF rhinorrhea not accompanied by intracranial lesion. The CSF rhinorrhea stopped after the operation, but acute hydrocephalus developed on the postoperative second day, and a ventriculospinal shunt was performed. The authors report a case of acute hydrocephalus occurring after the repair of the CSF rhinorrhea, a development that, to our knowledge, has never been reported in the literature.

PURPOSE: To evaluate the results and efficacy of posterior dual plating for distal shaft fractures of the humerus. MATERIALS AND METHODS: We retrospectively analyzed 12 patients, who underwent open reduction and internal fixation using posterior dual plating for distal shaft fractures of the humerus, between July 2007 and July 2015, with at least 6 months of follow-up. After locating the radial nerve without dissection via posterior triceps splitting, the fracture was stabilized using a short 3.5 mm locking compression plate. Then additional fixation, using a long 3.5 mm locking compression plate, was performed. The clinical outcomes were assessed in accordance with the Mayo Elbow Performance Index (MEPI) scoring system, and the radiological outcomes were assessed using serial plain radiographs. RESULTS: Eleven patients (91.7%) had bony union, and the mean union period was 13.9 weeks. In one patient, delayed union was treated by autogenous iliac bone graft at 8 months after surgery, which resulted in bony union. The mean MEPI score was 95.8, and the clinical outcomes were excellent in 9 patients and good in 3 patients. Postoperative complications included 1 elbow stiffness by heterotopic ossification and 1 temporary radial nerve palsy. One patient with temporary radial nerve palsy was completely recovered within the first 4 days after surgery. CONCLUSION: Posterior dual plating for distal shaft fractures of the humerus revealed satisfactory clinical and radiological outcomes. It can be a useful alternative to provide stable fixation without the need for a dissection of the radial nerve.
