A 5-year-old Chihuahua dog was evaluated for a tetraparesis. The dog was presented with a non-ambulatory tetraparesis and neck pain. Radiography demonstrated an atlantoaxial (AA) subluxation and increased distance between the dorsal arch of the C1 and the dorsal spinous process of the C2. The AA joint was fixed with ventral transarticular fixation using two screws under fluoroscopic guidance. Neck brace was applied during 3 weeks post-operation. After 4 weeks, the dog was fully ambulatory with improved neurological function. Postoperative radiographs confirmed reduction of the luxation and no migration of screws. The dog showed complete resolution of clinical signs without signs of recurrence till 4 months after operation. Proper angulations of screws provided under fluoroscopic guidance, enabled adequate stabilization of the AA joints using ventral transarticular screw fixation which improved neurologic outcome of the patient.

Silicone (polydimethylsiloxane) has widely been used in breast augmentation and other cosmetic procedures. Despite the stability of its chemical nature, local and systemic adverse reactions associated with silicone have been reported. There were several patients who suffered from pulmonary embolism associated with injection of silicone. Silicone-induced pneumonitis and sudden death after subcutaneous injection of silicone has been also described. However, there is no case in the literature of clinically diagnosed silicone-induced pulmonary embolism in Korea. We experienced 2 women who developed respiratory symptoms after illicit subcutaneous injection of silicone for the purpose of colporrhaphy. One patient was admitted because of dyspnea, chest pain, hemoptysis and bilateral pulmonary infiltration after repeated injection of silicone. Pulmonary function test initially showed severe restrictive pattern and transbronchial lung biopsy disclosed numerous oil-like material filling the alveolar septal capillaries and macrophages. High resolution C. T., bronchoalveolar lavage, transbronchial lung biopsy and pulmonary angiogram disclosed abnormalities compatible with silicone fluid-induced pulmonary embolism. The other patient expired shortly after arrival in the emergency room. It is suggested that illicit injecion of silicone fluid carries serious respiratory problems and can induce pulmonary embolism followed by acute respiratory failure.

Pulmonary histiocytosis X is a granulomatous disorder of the lung of unknown cause. Patients with this disease often complain of cough, dyspnea on exertion and, occasionally, chest pain from pneumothorax or bone involvement. However, DI is uncommon in these patients. We report a case of primary pulmonary histiocytosis X with central diabetes insipidus. A 23-year-old man presented with dyspnea suffered from dry cough, exertional dyspnea, polydipsia and polyuria for 4 months. He was a heavy smoker. He was found to have reticulonodular interstitial opacities on chest X-ray film. High-resolution computed tomography revealed thin-walled cysts of various sizes in both lungs. Open lung biopsy was done. On light microscopic examination revealed proliferation and infiltration of Langerhans cells. Immunohistochemically, Langerhans cells showed strong cytoplasmic staining with S-100 protein and electronmicroscopic examination showed Birbeck granules in Langerhans cells. Water deprivation test showed central-type diabetes insipidus and brain MRI showed no abnormal lesion on suprasellar region. Smoking cessation was recommended. He was treated with oral desmopressin.

A 6-year-old castrated male Shih-tzu was presented because of a 1-month history of progressive tetraplegia. On the basis of the findings of neurological examination, radiographs and magnetic resonance imaging, herniated intervertebral disc of C4-C5, C5-C6 and C6-C7 compressed spinal cord. The oxygen-ozone was intra-operatively injected into the C4-C5 and C6-C7 intervertebral disc and a ventral decompression performed at C5-C6 intervertebral space. Immediately after the surgery, neck pain was disappeared and three weeks after surgery, there was complete resolution of the neurological deficits with normal gaits. On magnetic resonance images at 2-month after surgery, herniated disc materials of C5-C6 and C6-C7 were completely removed and that of C4-C5 remarkably reduced. Consequently decompression which was performed at all of the three lesions resulted in good clinical outcome without additional internal fixation for minimizing postoperative instability.

This study is a qualitative one that used a phenomenological study method to provide basic data for nursing practice by understanding the essence and meaning of middle aged men's hemiplegic experience after stroke. At D hospital which is located in S city, 8 hemiplegic participants who were hospitalized between 24th November, 2014, and 6th December, 2014, participated in in-depth interviews. The experiences of the participants were categorized into 6 criteria, viz. 'Thorny path on a long journey', 'Broken brakes', 'Crossroads of the mind', 'Burden of head of household', 'Signpost that lights the darkness', and 'Route to a second life', and 16 theme clusters were included in these categories. As the sequelae and complications, such as physical pain, psychological conflict and role disorder, due to stoke in middle aged men, seriously affect their quality of life, this study attempted to understand the effect of these problems and provide new insight into nursing practice. Also, it is important to prevent the recurrence of stroke in the patients, facilitate their recovery, and help them to maintain healthy lives through the reestablishment of their role in the home and society, including through the resolution of their physical and psychological problems.

Purpose: Biphasic calcium phosphate (BCP), a widely used biomaterial for bone regeneration, contains synthetic hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP), the ratio of which can be adjusted to modulate the rate of degradation. The aim of this study was to evaluate the clinical and radiographic benefits of reconstructing peri-implant bone defects with a newly developed BCP consisting of 60% β-TCP and 40% HA compared to demineralized bovine bone mineral (DBBM). Methods: This prospective, multicenter, parallel, single-blind randomized controlled trial was conducted at the periodontology departments of 3 different dental hospitals. Changes in clinical (defect width and height) and radiographic (augmented horizontal bone thickness) parameters were measured between implant surgery with guided bone regeneration (GBR) and re-entry surgery. Postoperative discomfort (severity and duration of pain and swelling) and early soft-tissue wound healing (dehiscence and inflammation) were also assessed. Data were compared between the BCP (test) and DBBM (control) groups using the independent t-test and the χ² test. Results: Of the 53 cases included, 27 were in the test group and 26 were in the control group. After a healing period of 18 weeks, the full and mean resolution of buccal dehiscence defects were 59.3% (n=16) and 71.3% in the test group and 42.3% (n=11) and 57.9% in the control group, respectively. There were no significant differences between the groups in terms of the change in mean horizontal bone augmentation (test group: -0.50±0.66 mm vs. control groups: -0.66±0.83 mm, P=0.133), postoperative discomfort, or early wound healing. No adverse or fatal complications occurred in either group. Conclusions: The GBR procedure with the newly developed BCP showed favorable clinical, radiographic, postoperative discomfort-related, and early wound healing outcomes for peri-implant dehiscence defects that were similar to those for DBBM.

Purpose: To analyze the clinical outcome after ultrasound guided multiple dry needlings and local steroid injection for acute calcific tendinitis of shoulder. Materials and Methods: Twenty patients with acute episode of pain by calcific tendinitis of shoulder with average age 58.2 (50~70 years) and follow-up of 18 months in average (range, 12~24) were included in study. There were 18 patients with right and 2 with left sided involvement. All patients had calcific deposits in the supraspinatus tendon. All patients underwent standardized nonoperative treatment protocol, consisting of 5~12 MHz high resolution ultrasound guided multiple dry needlings with 18 guage needle, followed by 2% lidocaine 1cc and 40 mg/ml depomedrol 1cc injection at site of calcific tendinitis. The outcome was assessed by UCLA shoulder score, range of motion and VAS score. A statistical analysis with ANOVA and Tukey's post-hoc test with the significance level at 5% was performed using SAS 9.1 software (SAS Institute, Cary, NC). Results: All patients got continuous relief of pain right after the procedures until final follow-up. Before the procedures, the UCLA scores were fair in 15 patients and poor in 5. After the procedures, the UCLA scores were excellent in 16 patients and good in 4. All cases revealed no limitation of shoulder function. The average VAS score decreased from 8.9 before the procedures to 0.5 at final follow-up (p<0.0001). No complication was encountered. Conclusion: An ultrasound guided local steroid injections following multiple dry needlings would be one of the useful treatment modality for the acute calcific tendinitis of shoulder.

Purpose: We analyzed the result of autologous bone marrow stromal cell transplantation with or without cancellous chip bone allograft for benign long bone lesions. Materials and methods: Since July 1996, eight benign bone lesions treated by curettage, cancellous chip bone allograft and bone marrow or marrow stromal cell transplantation were observed for resolution of clinical symptoms, new bone formation and consolidation. There were 6 males and 2 females. Average age was 24 (range 8 to 47) years old. Histologic diagnoses were 5 fibrous dysplasia, 2 simple bone cysts and one chondroblastoma and fibrous cortical defect each. Mean follow-up period was 16.3 (range 3 to 84) months. Results: In all four symptomatic patients, the pain was subsided in two weeks after surgery. New bone formation in the lesion was observed at 4 weeks, which incorporated into surrounding normal bone around 8 weeks. There were one pathologic fracture through the lesion at 3 weeks and one recurrence of simple bone cyst at 5 months postoperatively. Conclusion: Bone marrow or marrow stromal cell transplantation for bone defects from curettage of benign bone lesions, with or without cancellous chip bone allograft revealed rapid healing. Though it was the result of short-term follow up, it supports that bone marrow stromal cell transplantation will be very useful for the treatment of benign long bone cysts or other lesions. The complete curettage of inner cystic wall is important to prevent later recurrence, and the rigid internal fixation is also needed in selected high risk lesions of fracture.

Purpose: Intussusception is one of the most common causes of an acute abdomen in infancy. The majority of pediatric cases of intussusception are of the ileocolic type and usually idiopathic. Small bowel intussusception is rarely diagnosed in children, and few cases have been reported. The purpose of this study was to determine the clinical features and causes of small bowel intussusception in children. Methods: We retrospectively reviewed the clinical and radiologic findings of 21 children with small bowel intussusception who were admitted to Seoul National University Children's Hospital between March 2005 and January 2010. Results: The clinical presentation of small bowel intussusception included abdominal pain or irritability (85%), vomiting (23%), fever (14%), bloody stools (14%), and abdominal masses (4%). Six patients required surgical management. Ultrasonography showed that the mean diameter of the lesions and mean thickness of the outer rims were 1.6${\pm}$0.7 and 1.7${\pm}$1.8 mm, respectively. Eleven lesions were located in the left abdominal or paraumbilical regions. Children who underwent surgical management were older than children with transient small bowel intussusception (mean age, 51 vs. 109 months). The mean diameter of the lesions and mean thickness of the outer rims were greater in the surgically-managed group. The location of intussusception was not significantly different between the two groups. Conclusion: Small bowel intussusception was spontaneously reduced in a large number of pediatric patients. However, sonographic demonstration of larger size, older age, and pathologic lead point warrant surgical intervention.

Purpose : The diagnosis of Meckel's diverticulum is difficult and delayed because it presents with various clinical symptoms. We evaluated clinical, imaging and pathologic findings of Meckel's diverticulum to facilitate detection of Meckel's diverticulum in children. Methods : Review of clinical, imaging, surgical and pathological findings in 10 children aged 7 days to 14 years with Meckel's diverticulum during an 8-year period, 1993-2001, at Ewha Womans University Hospital was undertaken. Results : The male to female ratio was 2.3 : 1. The chief complaint was painless lower gastrointestinal( GI) bleeding; others were abdominal pain, abdominal distention and vomiting, in order of frequency. The diagonsis before surgery were Meckel's diverticulum in 5 patients, non-reducible intussusception in 3 patients and intestinal obstruction in 2 patients. The diverticulum was located between 35 cm to 70 cm proximal to the ileocecal valve. The length of the diverticulum ranged from 4 cm to 12 cm and 80% of it was within 5 cm. A Meckel scan($^{99m}Tc-pertechnetate$ scintigraphy) after cimetidine administration was done in 6 cases. All 5 cases that presented with lower GI bleeding had ectopic gastric mucosa confirmed on pathology. Out of 5 cases of ectopic gastric mucosa, only 4 cases were positive on the Meckel's scan. Conclusion : In cases of unexplained GI bleeding, obstruction, or inflammation diagnostic workup should be carried out to rule out Meckel's diverticulum. Laparoscopy, high resolution ultrasonography and computed tomography of the abdomen may be indicated in the assessment of pediatric patient with lower GI bleeding, especially in patients with suspected bleeding from Meckel's diverticulum showing negative Meckel's scan.
