PURPOSE: This study is for the evaluation of low tesla(0.064T) MR imaging diagnostic accuracy in the internal derangement of the knee. MATERIALS AND METHODS: We retrospectively analysed the MR images of 36 injured knees of 35 patients. The presence of tear was determined by arthroscopy or surgery in all cases. RESULTS: The sensitivity, specificity, accuracy, positive predictive value, negative predictive value of low tesla MRI for the diagnosis of anterior cruciate ligament injury were 83%, 88%, 86%, 77%, 91%, for the posterior cruciate ligament 75%, 95%, 86%, 92%, 83%, for the medial collateral ligament 83%, 96%, 92%, 91%, 92%, for the lateral collateral ligament 67%, 97%, 94%, 67%, 97%, for the menisci 75%, 93%, 89%, 75%, 93%. CONCLUSION: The low tesla MRI is an accurate method in detection and evaluation of the internal derangement of the knee.

Gottron's acrogeria syndrome is a rare genetic disease of unknown etiology with some features suggestive of accelerated aging. The typical clinical presentation consists of premature aging of the skin with atrophy of the cutis and the subcutis. After a brief review of the literature available on this syndrome, we report a case of Gottron s acrogeria syndrome in a 19 year-old man whose right rectus femoris muscle had a fibrotic contracture.

STUDY DESIGN: A review of literature including definition, diagnosis and treatment of neuropathic pain. OBJECTIVES: To review and discuss the treatment guideline for neuropathic pain. SUMMARY OF LITERATURE REVIEW: Neuropathic pains are characterized by partial or complete somatosensory change caused by various disorders affecting central and peripheral nervous system, and are especially problematic because of their severity, chronicity and resistance to simple analgesics. MATERIALS AND METHODS: Review of literature. RESULTS: Tricyclic antidepressants and the anticonvulsants gabapentin and pregablin were recommended as first-line treatments for neuropathic pain. Opioid analgesics and tramadol were recommended as second-line treatments that can be considered for first-line use in selected clinical circumstances. Other medications such as dual reuptake inhibitors of both serotonin and norepinephrine would be used in severe cases. More invasive interventions (e.g., spinal cord stimulation) may sometimes be helpful. CONCLUSIONS: Treatment must be individualized for each patient and aggressive, combinatory pharmacotherapy and multidisciplinary approach are recommended for the treatment of neuropathic pain.

Pulmonary embolism of lipiodol or ethanol may occur inadvertently during the procedure of diagnostic or therapeutic embolization. We studied the nature of pulmonary damage, and its relation to the amount of lipiodol and ethanol embolized into the lung. Various doses of embolic agents(lipiodol 0.4cc/kg, 0.08cc/kg, absolute ethanol 0.4cc/kg, 0.03cc/kg and normal saline 0.4cc/kg)were injected intravenously through femoral vein in 50 rats(10 rats in each group). Pulmonary pathologic changes were analyzed on the 3rd and 28th days subsequent to injection. On the 3rd day, three of 10 lipiodol cases and all(10) ethanol cases showed multifocal pulmonary hemorrhages. Accompanying inflammatory cell infiltration was found only in lipiodol cases. On the 28th day, one of 10 lipiodol cases and four of 10 ethanol cases showed non-specific pneumopathy suggesting mild focal pulmonary fibrosis. The degree of pulmonary damage appeared to depend on the amount of injected embolic agents although their safety doses could not be clarified exactly. Therefore, we suggest careful injection of embolic agents, especially ethanol, during the embolization procedure to prevent possible pulmonary damage by inadvertent pulmonary embolism.

PURPOSE: To evaluate the effects and usefulness of fiuroscopy guided celiac ganglion block after marking of needle path with CT scan. MATERIALS AND METHODS: Celiac ganglion block with 100% ethyl alcohol was performed in 50 cancer patients who were inoperable and had intractable abdominal pain. Duration and degree of pain relief after the procedure and its complication were analyzed. RESULTS: Early pain relief was observed in 98% and long term relief in 68% without serious complication. CONCLUSION: Fluoroscopy guided celiac ganglion block after marking of needle path with CT scan was a safe and valuable procedure in relieving intractable pain in terminal cancer patients and reduced the time in the CT room.

We analysed the 49 probands of autosomal dominant polycystic kidney disease (ADPKD) in Korea to elucidate clinical and genetic characteristics. 1) Family history of renal disease or ADPKD was taken from 44% of probands; hypertension 88%, cerebrovascular attack 64%, end stage renal disease 16%. 2) From the family screening with renal ultrasonography, we have confirmed dominant trait in 24 families. We found 2 families which have suspicious new mutations. 3) We performed linkage analysis of 15 families. The PKD-1 to non PKD-1 ratio was 13 : 2. 4) The male to femal ratio was 17 : 32 and age at diagnosis was 41 (24-65)years (mean (range)) in male, 45 (26-68) years in female. 5) The factors leading to the diagnosis of ADPKD were flank pain (23%), incidental finding (17%), palpable abdominal mass (11%), headache (9%) and gross hematuria (9%) 3) Hypertension (80%), azotemia (43%), flank pain (42%), renal calcification (42%), gross hematuria (33%) and cyst hemorrhage (25%) were renal complications. There were 2 renal cell carcinoma cases. 4)Liver cyst (82%) was the most common extrarenal manifestations. There were colonic diverticulosis (13%), cerebral artery aneurysm (7%), adrenal cyst (4%) and pancreatic cyst (2%). Results of our study revealed the clinical and genetic characteristics of ADPKD in Korea. We found only 44% of family history of renal disease, variable initial manifestations, variable renal and extrarenal complications. And we also found the similar percentage of PKD-2 (13%) to that (5-15%) of western countries, but it is necessary to study with more patients and families.
