BACKGROUND: To report the radiological and clinical outcomes of internal fixation using distal clavicle hook plates for distal clavicle fractures. METHODS: From April 2008 to December 2012, 32 patients with distal clavicle fractures underwent surgery using an AO hook plate. The reduction was qualified and evaluated according to the radiological findings. The evaluation of the clinical outcomes was performed with the University of California at Los Angeles (UCLA) score, the Korean Shoulder score, and the visual analogue scale (VAS) pain score. RESULTS: By radiological evaluation, we found that 31 of 32 patients showed anatomical reduction and solid bone union. Although we obtained satisfactory UCLA scores, Korean Shoulder Scale scores, and VAS pain scores, 12 cases of complications were present. We found 4 cases of osteolysis of the acromion, 1 case of nonunion, 3 cases of periprosthetic fractures, 3 cases of subacromial pain, and 1 case of skin irritation. We performed re-operations in 2 patients. CONCLUSIONS: To avoid complications associated with clavicle hook plates, choosing the appropriate hook size and bending of the hook according to the slope of the acromion undersurface is critical. Also, we believe that early removal of clavicle plates may help reduce complications.

Unilateral renal agenesis is uncommon congenital condition with important implication when operation is performed. We report on two cases of unilateral renal agenesis but blind loop of ureter in a 2 year male child with vesical diverticulum and a 8 year old girl with contralateral hydronephrosis. An excretory urogram of the former revealed nonvisualization of left kidney and normal right kidney, it of the latter showed marked hydronephrosis of right kidney and nonvisualization of left kidney. These cases were finally confirmed by exploratory surgery with transvesical retrograde pyelography and histopathological findings of resected surgical specimen.

Teratoma of the testis is rare in testicular tumors and usually has more than one germ cell layer. Recently, we experienced one case of testicular teratoma in 19 years old adolescence, admitted to the department of urology, Chungnam National University Hospital. Histopathologic finding revealed the testicular teratoma with 3 germ layers. Herein, we report this one case of testicular teratoma with review of related literatures.

Avulsion fracture of medial cuneiform by tibialis anterior tendon is quite rare. It has been reported about the avulsion fracture and surgical repair of tibialis anterior tendon rupture at distal insertion site of medial cuneiform in Korea. We report a case of right foot medial cuneiform avulsion fracture by tibialis anterior tendon after autobike accident and describe this case with a review of literature.

BACKGROUND: Puffer fish can be the source of lethal flood poisoning in humans. Tetrodotoxin(TTX) poisonings are not infrequency seen in Korea, but there are few clinical reports. So we reviewed the patients of TTX poisoning and analyzed the clinical characteristics of patients. METHODS: A retrospective study was performed of 40 patients who visited Chung Ang Gil Hospital from Jan. 1, 1995 to May. 31, 1998 with a diagnosis of TTX poisoning by a review of patients' medical records and telephone inquiries, The diagnosis of TTX poisoning was made by causal links between consumption of puffer fish and the development of typical symptoms of tetrodotoxication. The clinical severity of the patients in this study was classified according to the classification of Fukuda. RESULTS: Mean age of the patients was 40 years. The highest incidence was in the 4th decade in 21 patients(52.5%). The ratio of male to female was 3.44:1, Seasonal distribution excluding cases in 1998 was 12 patients in spring, 6 in summer, 5 in autumn and 12 in winter. The mean interval between consumption and symptom onset was 137 minutes. Common initial symptoms were circumoral numbness(32 patients) and paresthesia of extremities(24 patients). Various symptoms were developed after ingestion of puffer flesh such as neuromuscular(39 patients), cardiovascular/pulmonary (23 patients) and gastrointestinal (16 patients) system. Mean recovery time from the onset of symptom was 22.00 hours. All were treated with symptomatic and supportive measures and recovered completely without sequelae. In 2 cases ventilatory supports were applied for 18.5 hours and 31.5 hours respectively.

PURPOSE: The purpose of this study was to evaluate effect of alpha-lipoic acid on apoptotic cell death in rat hippocampal neuron following transient forebrain ischemia-reperfusion (I/R) injury. METHODS: The four-vessel occlusion method was used to induce transient I/R injury in the forebrain of Sprague-Dawley rats. In the treatment group, alpha-Lipoic acid (LA) was administered subcutaneously at 50 mg/kg/day for 7 days before induction of I/R injury. RESULTS: Pretreatment with LA significantly reduced the number of TUNEL-positive neurons in the pyramidal cells layer of the hipocampal CA1 region 5 days after the ischemia, suggesting a marked reduction of apoptotic cell death. Pretreatment with LA also resulted in marked suppression at the transcript level of mRNA for caspase-3 at 24 hours, and decreased concentration of the active form of caspase-3 protein in the hippocampus at 1, 3, and 5 days after I/R injury. Furthermore, as indicated by western blot analysis, the concentration of apoptosis-inducing factor (AIF) in the hippocampus was reduced at 1 and 3 days after a transient I/R injury by pretreatment with LA. CONCLUSION: The results of this study suggest that LA has the potential to prevent neuronal cell death in the hippocampus by inhibiting intracellular signaling pathways responsible for apoptosis following transient I/R injury.

PURPOSE: The purpose of this study is to evaluate the clinical and radiologic results of using Acutrak screws for treating ankle medial malleolar fracture. MATERIALS AND METHODS: We reviewed 38 cases of ankle medial malleolar fracture treated with Acutrak screws from February 2005 to May 2008. RESULTS: In clinical result, there were 30 exellent cases, 7 good cases, 1 fair case. In radiologic result, there is no case with reduction loss. Average union time is 10.5 weeks. CONCLUSION: We conclude that Acutrak screw fixation is a useful method for ankle medial malleolar fracture, there are many advantages in accurate anatomical reduction, small incision, short operative time.

Crohn's disease is one of the inflammatory bowel diseases and is characterized by the involvement of the entire depth of the intestinal wall from the anus to the mouth. Neurological complications rarely occur in Crohn's disease and recurrent transverse myelitis has not yet been described in association with it. We report a 50-year-old man with Crohn's disease accompanied by recurrent transverse myelitis. Inflammatory bowel diseases and demyelinating disorders may share an autoimmune pathophysiology.

PURPOSE: To evaluate displacement and morphologic changes of the temporomandibular joint (TMJ) disc in patient with internal derangement using magnetic resonance imaging (MRI). MATERIALS AND METHODS: One hundred and forty five MR images of TMJs in 73 patients were evaluated. Positional and morphologic changes of the TMJ discs were assessed. Lateral or medial disc displacement was also evaluated on coronal images. RESULTS: Among 63 discs with anterior disc displacement, 37 discs were assessed as a biconcave disc and 21 as a deformed disc. Rotational disc displacement was observed in 35 discs. Anteromedial disc displacement was observed in 29 discs, and anterolateral direction in 6 discs. Among 35 rotational displacement, 5 biconcave discs and 21 deformed discs were observed. CONCLUSION: Rotational and sideways displacement of TMJ discs were found to be common and an important aspect of internal derangement. This study also suggests that sagittal and coronal images of the TMJ have complementary abilities for an assessment of joint abnormality.
