Various surgical procedures for the treatment of post-traumatic syringomyelia have been introduced recently, but most surgical strategies have been unreliable. We introduce the concept and technique of a new shunting procedure, syringo-subarachnoid-peritoneal shunt. A 54-year-old patient presented to our hospital with a progressive impairment of motion and position sense on the right side. Sixteen years before this admission, he had been treated by decompressive laminectomy for a burst fracture of L1. On his recent admission, magnetic resonance (MR) imaging studies of the whole spine revealed the presence of a huge syrinx extending from the medulla to the L1 vertebral level. We performed a syringo-subarachnoid-peritoneal shunt, including insertion of a T-tube into the syrinx, subarachnoid space and peritoneal cavity. Clinical manifestations and radiological findings improved after the operation. The syringo-subarachnoid-peritoneal shunt has several advantages. First, fluid can communicate freely between the syrinx, the subarachnoid space, and the peritoneal cavity. Secondly, we can prevent shunt catheter from migrating because dural anchoring of the T-tube is easy. Finally, we can perform shunt revision easily, because only one arm of the T-tube is inserted into the intraspinal syringx cavity. We think that this procedure is the most beneficial method among the various shunting procedures.

Objective: We analyze pain relief, deformity correction and complication rate after percutaneous kyphoplasty for osteoporotic vertebral compression fractures. Methods: The authors retrospectively reviewed medical records and radiological findings of 32 patients who underwent percutaneous kyphoplasty for osteoporotic vertebral compression fractures. Results: The patients had significant pain improvement with the procedure. The visual analogue scale score reduced from 8.6 to 3.4 significantly after the procedure. The midline vertebral body height significantly increased postoperatively, but mean kyphotic angle did not. There was no serious complication except one case of epidural cement leakage without neurological impairment. Conclusion: Balloon kyphoplasty safely can reduce severe back pain and returned geriatric patients to higher activity levels. The midline vertebral height is restored significantly. However kyphotic deformity correction is not significant as contrary to what we expected from the present study before it was carried out.

The antrolith is a rare disease in the maxillary sinus. We experienced a 67-year-old female whose chief complaint was a intermittent dull pain of clinical, radiological and histological findings, we diagnosed it as antrolith in the left maxillary sinus and obtained results as follows: 1. Three radiopaque substances in the left maxillary sinus was revealed as 'Antroliths'. 2. These antroliths were movable in the left maxillary antrum and combined with maxillary sinusitis. 3. We supposed it internal origin of nidus in this case.

Adenoid cystic carcinoma is a malignant salivary gland tumor with typical histologic patterns. The majority of these tumors occurs in the minor salivary glands. especially mucosa of the hard palate. The authors experienced the patients, who complained the tumor-like soft tissue masses on the palatal and mouth floor area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed them as adenoid cystic carcinomas in the minor salivary glands, and obtained results were as follows : 1. Main clinical symptoms were a slow growing soft tissue mass with normal intact mucosa on the palatal area, and soft tissue mass with mild pain on the mouth floor area. 2. In the radiographic exarnminations, soft tissue masses were observed with invasion to adjacent structures, and moderate defined, heterogeneous soft tissue mass with enhanced margin, respectively. 3. In the histopathologic exarnminations, dark-stained, small uniform basaloid cells in the hyaline or fibrous stroma were observed as solid and cribriform patterns, respectively.

Both os trigonum syndrome and osteochondral lesion of talus (OLT) are common causes of ankle pain and usually affect ballet dancers or athletes. Lateral osteochondral lesions, which usually result from traumatic event, are mostly located anterolateral talar dome but rare central or posterolateral. Moreover, there are technical difficulties such as position of patient or additional posterior portal to address posterolateral lesion by arthroscopy. Meanwhile, treatment of os trigonum syndrome using arthroscopic approach has been reported in many literatures recently. However, it has not been reported to diagnose both os trigonum syndrome and posterolateral OLT together and treat arthroscopically at one stage. The authors report a case of male patient who was diagnosed as os trigonum syndrome with posterolateral OLT and treated simultaneously by hindfoot arthroscopy. Symptom was improved immediately after the operation, and radiological findings at postoperative 16 months verified remarkable healing.

Pulmonary paragonimiasis is the infectious disease of lung, due to 'Paragonimus westermani'. The clinical manifestations are various, and the main symptoms are chronic cough and persistent hemoptysis. Radiological findings mainly include thin walled cyst, migrating patch pulmonary infiltration, transient linear shadow, and hydropneumothorax, etc. The differential diagnosis should include pulmonary tuberculosis, pneumonia, other parasitic diseases, and rarely lung malignancy if the mass-like lesion is present. Recently, the incidence of paragonimiasis is very low. But the physicians should suspect paragonimus infection, if the patient has chronic respiratory symptom such as hemoptysis and lives in the endemic area such as Korea. A case of pulmonary paragonimiasis confirmed by histological basis of lung was presented with a review of the literature.

Occupational long-term exposure to inorganic dusts may cause a variety of lung diseases such as pneumoconiosis and chronic obstructive pulmonary disease (COPD). Diagnosis of pneumoconiosis and COPD, however, is currently dependent on radiological findings and pulmonary test, which are both late diagnostic tools. Therefore, there is a need to identify novel biomarkers in pneumoconiosis and COPD. Hence, in this current study we investigated the serum concentrations of YKL-40, interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-${\alpha}$) as biomarkers for pneumoconiosis and COPD in 161 retired male workers exposed to inorganic dusts. The serum concentration of YKL-40 was significantly increased with age, pneumoconiosis, and airflow limitation. The serum concentration of IL-6 was significantly higher in airflow limitation. These results suggest that serum concentration of YKL-40 is associated with age, pneumoconiosis, and airflow limitation. Also, serum concentration of IL-6 is associated with airflow limitation.

We present a case of autoimmune chronic pancreatitis in a previously healthy child without any history of autoimmune disease. A 12-year-old boy was admitted to the hospital with abdominal pain. The serum amylase, lipase, and IgG levels were elevated and autoantibodies (antinuclear antibody, antineutrophil antibody) were detected. An abdominal CT (computed tomographic) scan revealed diffuse enlargement of the pancreas. ERCP (endoscopic retrograde cholangiopancreaticography) demonstrated an irregular stricture of the main pancreatic duct in the pancreas tail. After two years of oral steroid and immunosuppressive drug therapy, the clinical, laboratory and radiological findings were improved. The patient has been symptom-free for 18 months after the discontinuation of medication.

Objective: Congenital dermal sinus is a rare congenital disease that results from the failure of the neuroectoderm to separate from the surface ectoderm during the process of neurulation, where there is communication between the skin and the deeper structures. Their pathogenesis, clinical course and treatment strategy are well known. We analyze our series and compare our results with other series. Methods: Twenty patients were diagnosed as congenital dermal sinus and confirmed pathologically from October 1986 to July 2003 at our hospital. We studied the patients' clinical manifestations, radiological findings and pathological profiles. Results: Seven cases were located in the suboccipital area and 13 cases were located in the spinal area. Interestingly, 4 of 13 spinal lesion cutaneous openings were located lower than the 3rd sacral body level. 8 of 20 lesions were terminated at neural structures, 4 of 20 lesions were terminated at the intradural portion and others terminated at the extradural portion. Nine anomalies were combined with the dermal sinus, including 4 lipomas, 2 Currarino's triad, 1 encephalocele, 1 myelomeningocele and 1 diastematomyelia. Eleven patients had dermoid tumors. Conclusion: Congenital Dermal Sinus must be surgically removed immediately if they are diagnosed. The surgical procedure of congenital dermal sinus is complete removal, but in some cases, complete removal is impossible. In those cases, we removed all epithelial tissues. We consider sacrococcygeal dimple almost invariably have no connection with intraspinal structures. But, if other cutaneous manifestations are combined with cutaneous pits, it can communicate with the sacrococcygeal dimple.

Background: The aim of this study was to analyze the clinicopathological and immunohistochemical features of primary central nervous system lymphoma (PCNSL) cases occurring in Indian patients and also study the utility of the crush smear preparation in intraoperative diagnosis. Materials and Methods: The immune status, clinical, radiological details, immunohistochemical profile, histopathological findings and cytological features in smear preparation of 32 cases of PCNSL were analyzed. Patients with systemic NHL and skull-base lymphomas were excluded. Results: The mean age of our patients was 52 years with a male: female ratio 1:1. A periventricular location was found in 62.5% of patients. None of our PCNSL cases were associated with AIDS. All cases except one were diffuse large B-cell lymphomas. Intraoperative diagnosis using crush smears allowed correct prediction in 93% of cases. Conclusions: Our study shows that PCNSL is seen predominantly in immunocompetent patients in India. The age of presentation is relatively young as compared to the West. Our study also stresses the utility of crush smear preparation in establishing an intraoperative diagnosis.
