Surgery for a mid-esophageal lesion requires an open thoracotomy, But authors resected out a stenotic thoracic esphageal lesion with laparoscopic instrument without open thoracotomy. The patient was 50 years old woman with a long history of progressive dyaphagia. A small (3 cm in diameter) smooth ovoid submucosal mass lesion was found at 26 cm distal from incisor on both esophagoscopy and esophagogram. Two 5 mm and two 10 mm trocars were inserted into the right pleural cavity under general anesthesia with double lumen endotracheal tube, An induced pneumothorax by insuffulation of CO2 gas made lung collapse and a good exposure of esophagus. Transorally introduced esophagoscope helped to demonstrate the exact location of lesion and also to give a guide at safe excision of mass with prevention of mucosal perforation. The lesion was found to be a congromeration of an inflammed hilar lympnode and hypertorphic esophageal muscle. The entire lesion was carefully dissected from esphageal mucosa and resected out en bloc. A chest tube was introduced through a trocar site. The lung was reinflated immediately. Post-operatively patient was very comfortable. Laparoscopic surgery is very effective and safe, and it could be applied for the resection of lung bullae, benign pulmonary neoplasm and for an excision of benign esophageal tumor.

We reviewed forty five cases of intracranial arteriovenous malformation (AVM) who were admitted in Seoul National University Hospital within recent 7 years; thirty one patients revealed intracerebral hemorrhage and fourteen patients showed seizure or progressived focal neurologic deficit as an initial presentation. To evaluate the natural history of AVM after initial hemorrhage, out of these 45 cases, we selected 22 cases who were, operated or not, observed naturally for at least 1 year. To know the post operative course, we also selected 18 cases who were operated on. Thses two groups were compared with respect to the mortality, morbidity, frequency of rebleeding or seizure, which were 9%, 27%, 55%, 27%, in the former, and 0%, 17%, 0%, and 28% in the latter. Among the 14 patients whose initial presentation was not intracranial bleeding, 9 had seizure, 5 had progressive focal neurologic deficit, and 4 had both. During the follow-up period (average 5 years), only one patient had intracranial bleeding. Seizures in this group were relatively well controlled by regular antiepileptic regimen. Out of the 2 cases who were operated for seizure control, one had considerable degree of neurologic deficit after operation. From above evidences, we tentatively conclude that the AVM with initial bleeding should be better operated on if accessible, whereas the AVM without initial bleeding should be best managed conservatively. For a more definite conclusion, large, radomized controlled studies should be done again which, however, may meet ethical problems.

Metastatic brain parenchymal tumors are among the most important cause of death in patients with cancer, but many physicians didn't have any efforts to treat of metastatic tumors because of their poor responses of treatment. With the recent development of MR techniques, we could diagnose and treat them earlier. Recently many reports for prognostic factors of metastatic brain parenchymal tumors led to assume a more active attitude toward the diagnosis and treatment. We analysed 250 cases of metastatic brain parenchymal tumors diagnosed with the brain CT scan or MRI scan at Yonsei University, Severance Hospital from January, 1992 to December, 1995 and following results were obtained. 1. Metastatic brain parenchymal tumors are found in 254 cases(38.5%) of all intracranial neoplasms. 2. The most common primary tumor is lung cancer(154 cases, 61.6%) followed by breast cancer (30 cases, 12%), GI cancer (15 cases, 5.6%) in the order and melanoma (11.9%), rectal cancer (11.3%), lung cancer (8.6%) exhibit relatively high rate of intraparenchymal metastasis in the order. 3. The most common presenting symptom and sign is headache(52.8%) followed by motor deficit (32.4%), nausea and vomiting(21.6%). 4. Metastatic brain parenchymal tumors are detected simultaneously (73 cases, 28.8%), precociously (9 cases, 3.6%), after (153 cases, 61.2%) diagnosis of the primary tumor. Interval between the diagnosis of primary tumor and development of intracerebral metastasis is short in lung cancer (15.2 month) and long in breast cancer (43.1 month), nasopharyngeal cancer (51 month). In radiologic findings, the lesions were located in supratentorial areas in 186 cases, and in infratentorial in 36 cases. Ring type(63.6%) in enhancement is more than nodular type (33.2%). 5. Hemorrhages are found in 15 cases (7.6%) and calcifications in 2 cases. Density of lesions are hypodense(72.8%) than hyperdense on CT scan and high signal intensity in T1, or T2 weighted image of MRI are 66.7% and 88.9%. 6. Treatments for metastatic brain parenchymal tumors are conventional adiation therapy(165 cases, 66%), surgery(22 cases, 8.8%), gamma knife surgery (19 cases, 7.6%) in the order and there were 36 cases(14.4%) who didn't have any treatment. There are 132 cases(58.2%) who alive and 118 cases(47.2%) who dead. 7. Good predilicting findings in prognosis of metastatic brain parenchymal tumors are single lesion and supratentorial location. However, there are no significant value between prognosis and interval primary-to-metastasis, age, type of primary cancer, type of presenting symptom, size of edema.

Further understanding of male human papillomavirus (HPV) infection is necessary to prevent infection in men, as well as transmission to women. In our current study, we investigated patterns of HPV infection and genotype distributions in male genital warts using the Anyplex II HPV28 Detection kit. We reviewed the medical records of 80 male patients who presented to 5 neighborhood clinics in Ulsan, Korea, for the treatment of genital warts between April 2014 and January 2015. All patients underwent HPV genotyping. The prevalence and characteristics of HPV infection were analyzed, and the patterns of HPV infection according to age were assessed. Among the study patients, 13 (16.3%) were negative for HPV infection, 46 (57.3%) were infected with low-risk HPV, and 21 (26.3%) were infected with high-risk HPV. Patients with multiple HPV infection were more likely to have high-risk HPV infection (P = 0.001). The prevalence of HPV infection was much higher in samples obtained by tissue excision due to a definite lesion (P = 0.001). There were no differences in high-risk HPV infection (P = 0.459), multiple HPV infection (P = 0.185), and recurrence at diagnosis (P = 0.178) according to age. HPV-6 and HPV-11 were the most common type overall (39.7% and 13.8%, respectively). HPV-16 and HPV-18 were the most common high-risk infections (both 3.4%). HPV infection is not only commonly encountered in male genital warts, but is also accompanied by high-risk HPV and multiple infections.

Chiari malformation is a condition characterized by herniation of the posterior fossa contents below the level of the foramen magnum : The main pathologic change is downward displacement of the cerebellar tonsils to occlude the subarachnoid space at the level of the foramen magnum. For this reason, the practice of posterior fossa decompression in the treatment of syringomyelia with Chiari malformation has been widely accepted. In order to evaluate the usefulness of the procedure in the treatment of this condition, clinical data and surgical outcome in 20 patients who underwent posterior fossa decompression during the last five years were analyzed. The average age at presentation was 35.9(range 17 to 61) years. Chiari I malformation was found in 14 patients, and Chiari II malformation in six : weakness and pain were the most common symptoms. The most useful preoperative imaging study was magnetic resonance imaging. In order to expose the outlet of the fourth ventricle, all patients underwent suboccipital craniectomy and C1 or C1-2 laminectomy with the supportive procedure consisting of adhesiolysis and tonsillar elevation. Postoperatively, 75% of patients showed improvement, and the condition of 15% stabilized. Postoperative MRI was performed in 12 patients, and revealed that in 11 of these, the syrinx cavity had become smaller. Transient headache and vomiting was the most frequent postoperative complication. Patients with pain and numbness had a better prognosis than those with weakness and sensory loss, and it appears that in cases of syringomyelia with Chiari malformation, posterior fossa decompression is beneficial.

BACKGROUNDS: The Wada test is a useful method in predicting the laterality of a epileptogenic zone. However, past research reveals that material specificity has an influence on the lateralization We examined the material-specificity of memory and its change in epileptic patients to discover reasonable items on the Wada test for the proper lateralization of the epileptogenic zone. METHODS: We analyzed 45 patients with video-EEG-confirmed medial temporal lobe epilepsy (mTLE) and definite hippocampal atrophy by an MRI. Eight items were presented during the Wada test including 3 common objects, 1 geometric object, 1 color, 1 word, 1 phrase, and 1 math expression. We checked recognition memo-ry after recovery of hemiparesis and normalization of EEG. RESULTS: For the right mTLE group, recognition memory following a right hemisphere injection was significantly better than a left hemisphere injection for all categories. For the left mTLE group, a significant difference of scores was found for the left versus right hemisphere injection for common objects. When injected to the left hemisphere, all the items helped lateralization, but when injected to the right hemisphere, a phrase did not help with lateralization. CONCLUSIONS: Items with strong unilateral encodings do not help lateralizing the epileptogenic zone.
