Primary meningeal melanocytoma of the central nervous system is extremely rare. We report a case of meningeal melanocytoma associated with Ota's nevus as a recurrent form in a 53-year old male. The meningeal melanocytoma was removed from right parietooccipital lobe 4 years ago and recurred in right parietal, occipital and left frontal lobes. Ultrastructurally, the tumor cells were characterized by the presence of numerous melanosomes and premelanosomes in their cytoplasm. Moreover, the tumor was lacking in histologic and ultrastructural features of pigmented meningioma, melanotic schwannoma and prolonged clinical course was different from primary meningeal melanoma or metastatic malignant melanoma.

PURPOSE: To evaluate the change of iris-trabecular contact index (ITC index) after cataract surgery in acute angle closure glaucoma. METHODS: Twelve patients (17 eyes) who had a history of acute angle closure glaucoma underwent swept source optical coherence tomography before and after cataract surgery. Correlations between lens vault (LV), ITC index and intraocular pressure (IOP), anterior chamber depth (ACD), anterior chamber volume (ACV), and angle parameters were analyzed before and after cataract surgery. RESULTS: IOP (p = 0.007), ACD (p < 0.001), ACV (p < 0.001), angle parameters (p = 0.001), and ITC index (p = 0.012) were improved after cataract surgery. ITC index decreased from 88.42 ± 23.59% to 48.91 ± 35.13% after cataract surgery (p = 0.012). There was no correlation between LV and ACD (p = 0.075), ACV (p = 0.864), angle parameter (p = 0.112-0.707), or ITC index (p = 0.288) before cataract surgery. The correlations between ITC index and IOP (p = 0.021), ACD (p = 0.002), ACV (p < 0.001), and angle parameter (p = 0.001-0.030) were statistically significant before surgery but not statistically significant (p = 0.223/0.206/0.761/ 0.096-0.819) after surgery. CONCLUSIONS: ITC index significantly improved after cataract surgery, but part of angle closure was not resolved in some cases of acute angle closure glaucoma.

In a series of 20 young rats, three cortical lesions were made in each hemisphere. Two of these lesions were filled with avitene and gelfoam, while the third was left empty as a control. The animals were killed successively on weeks 1, 2, 4 and 8 after the operation. The results were as follows : 1) Although there was no difference in the type of tissue reactions, avitene was more rapid and profound than gelfoam in the process and degree of inflammatory reaction at the same periods. 2) Avitene biodegradaded more rapidly than gelfoam. 3) The extent of fibrosis and adhesion to the surrounding brain tissues were not grossly different between these two agents but more profound histopathologically in avitene at the same periods. With these results, we could conclude that the avitene was superior to the gelfoam as the hemostatic agent in neurosurgical area.

PURPOSE: To evaluate the efficacy of dynamic colpocystodefecography in patients with a pelvic organ prolapse. MATERIALS AND METHODS: A total of 63 patients, with or without stress urinary incontinence and pelvic organ prolapse, who visited our hospital between April 2002 and July 2003, were studied. All patients were available for physical examination and dynamic colpocystodefecography. The patient was seated on a radiolucent commode, which was upright on the end of a vertically oriented x-ray table. Deliberate efforts were made to ensure privacy. Fluoroscopic images were taken during resting, squeezing, Valsalva effort, voiding and defecation. RESULTS: On physical examination, cystocele, rectocele and rectal intussusception were revealed in 26 (36%), 20 (31%) and 7 cases (11%), respectively. On dynamic colpocystodefecography, cystocele, rectocele and rectal intussusception were revealed in 44 (69%), 32 (50%) and 15 cases (24%), respectively. Compared with the physical examination, 18 cases of cystocele, 12 of rectocele and 8 of rectal intussusception were newly found through dynamic colpocystodefecography. Enterocele and sigmoidocele were not found in the physical examination, but only found through dynamic colpocystodefecography in 4 and 5 cases, respectively. The degree of prolapse was more severe during defecation than voiding. CONCLUSIONS: Not all the pelvic organ prolapses were detected on physical examination. Radiological evaluation is necessary for a more accurate detection of a pelvic organ prolapse. Dynamic colpocystodefecography has the advantages of it's ability to be performed for physiological defecation and voiding status, as well as imaging of dynamic pelvic organ structures.

BACKGROUND: To date, a laparoscopic gastrectomy has been performed by a small number of surgeons around the world, but the laparoscopic approach has been extended to Billroth I and a total gastrectomy. To evaluate the validity of the procedure, we present the results of six patients who underwent a gastrectomy using a laparoscopic technique. METHODS: First, two patients had a totally intra-abdominal laparoscopic B-II gastrectomy, and one of two also had a bilateral truncal vagotomy. The rest had a laparoscopic-assisted gastrectomy. One patient had concurrently an open reduction and an internal fixation with a K-wire for a patellar fracture. Indications were (a) gastric outlet obstruction due to peptic ulcer disease in five patients and (b) duodenal ulcer bleeding in one patient. RESULTS: Except for one patient who had stump leakage, which was solved by conservative therapy, there were no complications or operative mortality. The operating time and the cost were less for the patients who had their operations later in the series and who had laparoscopic-assisted operation. CONCLUSIONS: These forms of laparoscopic gastric surgery for patients with complications of peptic ulcer disease may be useful from the standpoint of minimal access, rapid recovery, less pain, and good cosmesis.
