PURPOSE: To review the results of resections of heterotopic ossification around the hip in patients with central nervous system injuries. MATERIALS AND METHODS: Heterotopic ossification was resected in ten hips of eight patients and followed for at least one year. Average age was 38.1 years (range, 21-56 years). We reviewed the charts and the radiographs for overall patient function, location of the lesion, radiographic evidence of maturation and any recurrence. Heterotopic ossification was resected regardless of the result of bone scan. RESULTS: All patients showed improved function. Three minimal recurrences and one moderate recurrence were identified at the last follow-up radiography, but the range of motion had not decreased due to recurrence. CONCLUSION: Severe heterotopic ossification around the hip in patients with spastic paralysis was resected, and it was found that the range of motion was improved in all patients and that the chance of recurrence was minimal, even though the bone scan showed hot uptake on the bone scan.

Pyruvate dehydrogenase complex deficiency (PDCD) is one of the most common neurodegenerative
disorders associated with abnormal mitochondrial metabolism. Pyruvate dehydrogenase complex
plays an important role in glucose metabolism and generation of energy from carbohydrates. Potential
therapies for PDCD, include thiamine and ketogenic diet (KD), have been used with varying degrees
of success. However, the KD is too restrictive, and its serious complications, particularly in early
age of neonate or infancy are important drawbacks. Recently, the modified Atkins diet (MAD) for
intractable epilepsy has provided balanced nutrients. The complications can be expected to be less
frequent and well controlled. In this report, we describe an infant with PDCD confirmed by PDHA1
gene mutation through high-throughput sequencing technique of whole exome sequencing, who failed
to continue the KD, but made good progress on MAD.

BACKGROUND AND PURPOSE: The advances in the diagnosis and treatment of acute stroke increase the importance of providing these patients with timely medical attention. This study was designed to assess time delays in neurological evaluation and neuroimaging and to determine whether they are important obstacles to performing thrombolytic therapy. METHODS: Data were obtained between May 2004 and September 2006 from 195 consecutive patients who were admitted to Cheju National University Hospital for acute ischemic stroke within 24 hours of the onset of symptoms. We determined the time of the onset of symptoms, arrival time at the emergency department (ED), and times of neurology notification, neurology evaluation, and neuroimaging using interviews and by reviewing the medical record. RESULTS: Short onset-to-door time, performing computed tomography rather than magnetic resonance imaging, presence of aphasia or motor weakness, and severe initial neurological deficit were significantly associated with reduced in-hospital delays. Seventeen (20%) of the 85 patients who arrived within 3 hours of the onset of symptoms received intravenous thrombolysis. Mild neurological deficit, rapidly improving symptoms, and insufficient time to workup were the main causes of the nonreceipt of thrombolytic therapy in these patients. Only one patient did not receive thrombolytic therapy due to delay in neurology consultation. CONCLUSIONS: Whilst in-hospital delays were not major obstacles to performing thrombolytic therapy in this study, there is still a high probability of missing patients with mild-to-moderate stroke symptoms. More effective in-hospital organization is required for the prompt evaluation and treatment of patients with acute ischemic stroke.

PURPOSE: We evaluated the impact of renal tumor size on the oncologic and surgical efficacy of laparoscopic renal cryosurgery (LRC) according to our intermediate-term experience in Korea. MATERIALS AND METHODS: From June 2005 to October 2008, we enrolled 37 patients who underwent LRC for 40 renal tumors. Patients were stratified into four groups according to renal tumor size. Patients who presented with a maximum tumor diameter (MTD) of at least 1 cm but less than 2 cm were assigned to Group 1, those with an MTD equal to or greater than 2 but less than 3 cm were assigned to Group 2, those with an MTD equal to or greater than 3 but less than 4 cm were assigned to Group 3, and those with an MTD equal to or greater than 4 cm were assigned to Group 4. Oncologic and clinical outcomes in each group were compared. RESULTS: The four groups showed no statistically significant differences in preoperative variables, including age, sex, body mass index, American Society of Anesthesiologists scores, baseline renal function and hemoglobin, and length of hospital stay. Regarding surgical aspects, however, operation time, estimated blood loss, and postoperative complications were significantly increased in patients with larger tumors. Three patients in Group 3 required postoperative transfusions, and 1 patient in Group 4 required conversion to open renal cryosurgery. During the mean follow-up period of 31.6 months, radiologic evidence of tumor recurrence was found in only 2 patients in Group 4. CONCLUSIONS: In this series, LRC for renal tumors smaller than 3 cm was conducted safely without radiologic evidence of tumor recurrence during intermediate-term follow-up. For tumors larger than 3 cm, however, the transfusion rate increased, and for renal tumors larger than 4 cm, the tumor recurrence rate increased significantly.

OBJECTIVES: Many patients diagnosed with cancer suffer from various psychiatric symptoms such as depression, anxiety and insomnia as well as cancer itself. Patients with cancer are more vulnerable to possible adverse events of psychotropic medications. Although antidepressants are widely used among cancer patients, there is little information about tolerability of antidepressants. This study was conducted to compare tolerability of antidepressants in cancer patients referred for psychiatric consultation. METHODS: The participants were cancer patients who had been referred to psychiatrist for their psychiatric symptoms. We retrospectively analyzed the data of patients diagnosed with cancer from 9 general hospitals in Korea. The discontinuation rate for a 6 months period after treatment initiation for three antidepressants(Escitalopram, Mirtazapine, Paroxetine) were compared. RESULTS: Antidepressants were prescribed for 96.3% of subjects and Escitalopram 150(47.2%), Mirtazapine 92 (28.9%) and Paroxetine 76(23.9%) were prescribed frequently in order There were no significant differences in discontinuation rates among the three antidepressants during the 6 month period after initiation of pharmacotherapy. But there was a difference in discontinuation rates between inpatients versus outpatients(p<0.0001). CONCLUSIONS: In a naturalistic setting for the antidepressant treatment for cancer patients, it seems that there are no differences in discontinuation rates among these three antidepressants. It is therefore essential that such interactions are carefully considered when treating patients of antidepressants who already have cancer.

A 75 year old woman was admitted for evaluation of right lung mass. She was not a smoker. She had been diagnosed as uterine prolapse and during preoperative assessment a lung mass was found incidentally on simple chest X-ray. On chest CT scan, 3.5x2 cm sized homogeneous mass was located in the anterior segment of right upper lobe and there were multiple calcified lymph nodes in both hilum and mediastinal area. We performed diagnostic bronchoscopy, but no definite endobronchial mass was found. Next we did CT guided percutaneous fine needle aspiration biopsy. On microscopy, sulfur granules consisting of multiple granular basophilic centers with hyaline projection of branching filaments were noted. From this finding we made a diagnosis of pulmonary actinomycosis.

Churg-Strauss syndrome(CSS) or allergic angiitis and granulomatosis is a disorder characterized by pulmonary and systemic small-vessel vasculitis, extravascular granulomas, and hypereosinophilia. It occurs in individuals with asthma and allergic rhinitis. The diagnosis of CSS is made on the basis of clinical and pathologic features. According to 1990 American College of Rheumatology(ACR) criteria for the classification of CSS, 6 criteria were developed. The presence of 4 or more of these criteria yielded a sensitivity of 85% and a specificity of 99. 7%. We describe a case of CSS in a 62-year-old female who met all of 1990 ACR criteria, but presented as like a as rheumatoid arthritis initially. Clinical symptoms, laboratory and roentgenographic findings gradually responded to high dose prednisolone treatment and resolved 3 weeks later. After discharge, she has been treated with oral prednisolone in a tapering course. Although polyarthritis with eosinophilia, vasculitis, and neuropathy are clinical manifestations of rheumatoid arthritis, those maniestations frequently occur during the vasculitic phase of the CSS. This case suggests that thorough differentiation of extra-articular manifestations of RA from clinical manifestations of CSS is considered when we meet a patient who have polyarthritis and vasculitis.

After the introduction of antibiotics, empyema is a rare complication of retropharyngeal abscess caused by acute epiglottitis. But once it occurs, it may be a fatal outcome. Retropharyngeal abscess may spread to mediastinum and pleural cavity along the deep cervical fascia, then it can induce pneumonia, mediastinitis, empyema, and sepsis. Because of its fatal complication, early diagnosis and intensive surgical treatment, such as incision and drainage, is necessary. Now we have a experience of empyema caused by retropharyngeal abscess in a 56-year old diabetic patient with nephropathy. He was admitted to our hospital because of hoarseness and sore throat due to acute epiglottitis. Several days after his admission, he complained of swelling of neck, which was diagnosed as retropharyngeal abscess by the computerized tomography. Retropharyngeal abscess was managed with antibiotics, incision and drainage and culture revealed Peptostreptococcus prevotii. Subsequently empyema developed in his right chest, which was managed with closed thoracotomy, though, he expired due to progression of sepsis.

Hemobilia is defined as hemorrhage into the biliary tract as a result of a communication between the biliary tract and arteriovenous circulation. A classical triad of symptoms and signs are upper abdominal pain, gastrointestinal bleeding, and jaundice. Hemobilia is a rare condition that may be difficult to recognize; it is, nevertheless, important to include it in the differential diagnosis of gastrointestinal bleeding. The causes include accidental and iatrogenic trauma, gallstones, inflammation, vascular malformation, and tumors. Due to the frequent use of diagnostic and therapeutic procedures involving hepatobiliary and portal systems, there has been an increase in the incidence of iatrogenic hemobilia during the last two decades. Like hematuria and epistaxis, hemobilia may also occur in coagulopathy, but acquired coagulopathy with anticoagulation therapy is very rarely associated with this condition. We present a case of acquired coagulopathy following warfarin therapy that resulted in spontaneous hemobilia complicating acalculous cholecystitis and cholangitis.
