Cystic nephroma (CN) is a benign cystic neoplasm composed of mixed epithelial and stromal elements. Less than 200 cases have been reported. We had a patient, a 41-year-old woman, who had a huge typical CN. The patient was admitted for a right renal mass that was found incidentally. On laparaoscopic right nephrectomy, there was an encapsulated 7 cm multilocular cystic mass at the upper pole. Microscopically, the cystic wall was lined by a single layer of low cuboidal or hobnail epithelium without a solid area. The thin septa were composed of bland, ovarian type spindle cells. The main differential diagnoses were mixed epithelial and stromal tumor (MEST), low grade multilocular renal cell carcinoma, and tubulocystic carcinoma. The results of immunohistochemical staining were cytokeratin 7/19(+/+) and CD10(-) in lining epithelium, estrogen receptor/progesterone receptor(+/+) in stromal cells. After surgery, she was free of recurrence for 10 months. We report this rare case and compare it with other cystic renal tumors, especially MEST.

Entrapment syndrome of suprascapular nerve by a ganglion has been reported not frequently. We experienced a case of suprascapular nerve entrapment by ganglion which was treated with non-operative treatment, and report it with literature.

A clinical analysis of infective endocarditis was done in 34 patients who were admitted to National Medical Center from march. 1972 to June. 1984, and the results were as follows. 1) There was no difference in ratio between sexes. The prevalence was highest in the 3rd decade. 2) The important preexisting heart diseases were rheumatic heart disease(32.4%), congenital heart disease(17.6%) and undefined cardiac condition(20.6%) in order of frequency. 3) The common symptoms and signs on admission were fever(88.3%), cardiac murmur(79.4%), malaise(70.6%), dyspnea (64.7%), palpitation(55.9%) and hepatosplenomegaly(55.9%). 4) The positive blood culture was obtained in 15(47%) of the cases. Those who had not received antibiotics before admission showed higher rate of positive culture(72.7%) than in those who had received(33.3%). 5) The laboratary findings revealed anemia(73.5%), leukocytosis(35.3%), increased ESR(73.5%), microscopic hematuria(61.8%) and positive CRP(100.0%). 6) The EKG findings showed normal(11.8%), sinus tachycardia(32.4%), LV hypertrophy(29.4%), non-specific ST-T change(20.6%) and AV block(14.7%). 7) Vegetation was detected by echocardiography in 43% of cases and the most frequently involved valve was aortic(66.7%). 8) The combination of penicillin and aminoglycoside was effective in 86.4% of patients so treated.

Korean Journal of Obstetrics and Gynecology 2004;47(4):739-747
OBJECTIVE: The PapSure test, a combination of Papanicolaou smear cytology and speculoscopy, is a direct visual cervical cancer screening method. Speculoscopy, or magnified chemiluminescent examination (MCE), is a new visual method for the detection of cervical neoplasia. It utilizes low magnification and a special "blue-white" chemiluminescent light. The purpose of this study was to evaluate the effectiveness of PapSure test for cervical cancer detection, as compared with the Pap cytology alone. METHODS: This prospective, randomized, university hospital-based clinical study was performed in the outpatient clinic of the Department of Obstetrics and Gynecology at Dankook University Medical Center from July 1, 2002 to November 30, 2003. Of the 508 patients aged 17-81 years who had undergone conventional Papanicolaou cervical cytologic test, speculoscopy, and colposcopy, 254 cases underwent histopatologic diagnoses. RESULTS: Of the 508 patients, there were 131 (25.8%) PapSure diagnoses of positive, 377 (74.2%) of negative. Of the 254 histologic diagnoses, there were 166 (65.4%) diagnoses of benign, 37 (14.6%) of LSIL, 30 (11.8%) of HSIL, and 21 (8.3%) of carcinoma. Pap smear showed sensitivity of 79.5%, and specificity of 91.6%, whereas PapSure test showed sensitivity of 89.8%, and specificity of 77.1%. The addition of speculoscopy to the routine Pap smear resulted in finding 2 of the 30 (7%) women with HSIL which was not statistically significant, and 7 of the 28 (25%) women with LSIL which showed statistically borderline significance. CONCLUSION: PapSure test showed a higher sensitivity rate and a lower false negative rate than Pap smear only as a screening test. Pap smear cytology and speculoscopy seem to be additive, and so the PapSure test is thought to be a very effective method for detecting cervical neoplasia.

We report a case of spontaneous right carotid-cavernous fistula (CCF) in a proximal segment of persistent primitive trigeminal artery (PPTA) and combined vascular anomalies such as left duplicated hypoplastic proximal posterior cerebral arteries and a variation of anterior choroidal artery supplying temporal and occipital lobe. A 45-year-old male presented with progressive right exophthalmos, diplopia, and ocular pain. With manual compression of the internal carotid artery, a cerebral angiography revealed a right CCF from a PPTA. Treatment involved the placement of detachable non-fibered and fibered coils, and use of a hyperglide balloon to protect against coil herniation into the internal carotid artery. A final angiograph revealed complete occlusion of PPTA resulted in no contrast filling of CCF.

Journal of the Korean Academy of Rehabilitation Medicine 2001;25(6):987-992
OBJECTIVE: This study was designed to evaluate the effect of stretching on decreasing spasticity of ankle plantar flexor muscles by biomechanical assessments. METHOD: Twenty two ankle joints of nineteen patients with upper motor neuron lesion were included. The spasticity was assessed both clinically and biomechanically before and after stretching of ankle plantar flexor muscles by tilt table. For clinical assessment modified Ashworth scale (MAS) was used. For biomechanical assessment, ankle plantar flexor muscles were stretched isokinetically while EMG signals were recorded simultaneously and peak eccentric torque, stiffness index and stretch reflex threthold speed (SRTS) were measured. RESULTS: Two cases showed improvement in MAS after stretching but the others did not. SRTS of ankle plantar flexor was increased significantly while peak eccentric torque and stiffness index were unchanged. CONCLUSION: Passive stretching of ankle plantar flexor muscles decreased the stretch threshold, that is a neural component of spasticity but it did not decrease the mechanical component of spasticity.

A 29 years old woman had suffered from posterior neck and right shoulder pain for one year. She was given a spinal manipulation that was by a non-licentiate at a non-hospital. Posterior neck and shoulder pains were worsened and headache was developed after the spinal manipulation. She was recommended to be kept on the manipulation. Although physical finding was non-specific, radiologic findings of CT and MRI revealed atlantoaxial subluxation. After cervical immobilization and anti-inflammatory drug medication for three months, she recovered and did return to her work. We expect that atlantoaxial subluxation after spinal manipulation is not rare even in healthy young person without underlying pathology and can progress to serious complications unless detailed examination and management are undertaken.
