The prognosis of malignant ovarian tumor is poorer than that of borderline malignant ovarian tumor, Therefore an accurate diagnosis and estimation of the biologic behavior of the tumor are necessary for proper management of the patient. The histologic investigation of the tumor may provide information on the estimation of the malignant potential of tumor cells, but it may be a questionable method because of the subjective determination of tumor grade. Quantification of proliferative activity of tumor cells may play a role as an objective method to provide an estimation of the malignant potential of tumor cells. An evaluation of histologic findings was done on 84 cases of ovarian mucinous and serous tumors that were surgically resected and diagnosed during the period from January 1981 through July 1992. The proliferating cell nuclear antigen (PCN A) labelling index estimated from the immunohistochemical stain for PCN A and the Sphase fraction and porliferative index obtained from flow cytometric DN A analysis were assessed each other with histologic findings. The results are as follows: The presence of aneuploidy in malignant tumors was statistically significant as compared with benign tumors. The borderline malignant tumors showed no significant difference between the number of diploidy and aneuploidy. The PCNA labelling index, S-phase fraction and proliferative index tended to increase as the histologic grade of tumors went up. They were higher in malignant tumors than in others. The PCN A labelling index, S-phase fraction and proliferative index were higher in tumors with aneuploidy than in those with diploidy. In contrast to borderline malignant tumors, the PCNA labelling index in malignant tumors revealed a significant relation with the mitotic index. The S-phase fraction and proliferative index showed, in malignant tumors, a close correlation with the architectural grade and nucleolar grade, but not in borderline malignant tumors. Considering these results, the presence of aneuploidy, PCNA label.

Antifungal bacteria for biological control of plant diseases or production of novel antibiotics to plant pathogens were isolated in 1997 from various soils of Ansung, Chunan, Koyang, and Paju in Korea. Sixty-four bacterial strains pre-screened from approximately 1,400 strains were tested on V-8 juice agar against eight plant pathogenic fungi using in vitro bioassay technique for inhibition of mycelial growth. Test pathogens were Alternaria mali, Colletotrichum gloeosporioides, C. orbiculare, Fusarium oxysporum f. sp. cucumerinum, F. oxysporum f. sp. lycopersici, Magnaporthe grisea, Phytophthora capsici, and Rhizoctonia solani. A wide range of antifungal activity of bacterial strains was found against the pathogenic fungi, and strain RC-B77 showed the best antifungal activity. Correlation analysis between inhibition of each fungus and mean inhibition of all eight fungi by 64 bacterial strains revealed that C. gloeosporioides would be best appropriate for detecting bacterial strains producing antibiotics with potential as biocontrol agents for plant pathogens.

PURPOSE: To report a rare case of endophthalmitis caused by Shewanella algae after trauma. CASE SUMMARY: A 27-year-old man was referred for trauma caused by a fishing sinker in his right eye. On initial examination at another hospital, his visual acuity was light perception, and intraocular pressure was 50 mm Hg. On slit lamp examination, corneal edema and severe anterior chamber inflammation were observed. Consequently, the next day total pars plana vitrectomy, lensectomy, intravitreal silicone oil injection, and antibiotics injection were performed. After the operation, intraocular pressure was 15 mm Hg and the patient's pain was temporarily decreased. The presence of Shewanella algae in the vitreous culture was determined but antibiotic sensitivity was not proven. The patient received postoperative topical fortified vancomycin, ceftazidime, and tobramycin hourly and underwent intravenous antibiotic therapy. On postoperative day 25, the patient transferred to our hospital and ocular pain presented continuously. Intraocular inflammation was not severe but visual acuity was light perception because of retinal necrosis in the posterior pole. Therefore, the patient received topical fortified antibiotics and intravenous antibiotics therapy. On postoperative month 2, visual acuity was light perception and the patient's right eye progressed to pthisis bulbi. CONCLUSIONS: Here in the first case reported in Korea or other conturies of primary endophthalmitis by Shewanella algae after traumas. Shewanella algae endophthalmitis has a rapid progression and poor visual prognosis in spite of aggressive therapy.

PURPOSE: To report the effect and visual improvement of internal limiting membrane (ILM) peeling, and epiretinal membrane (ERM) peeling in symptomatic ERM with pseudolamellar macular hole. METHODS: This study included 27 eyes in 26 consecutive patients with ERM including pseudolamellar macular hole that underwent vitrectomy, ERM peeling, intravitreal gas tamponade, and maintained a face-down position for 7 days. ILM peeling was performed only in 13 eyes of 13 patients. The patients were divided into 2 groups: eyes with or without ILM peeling (14 eyes and 13 eyes, respectively) and the follow-up period was 12 months or more in all cases. The postoperative anatomic results based on optical coherence tomography (OCT) and improvement of best corrected visual acuity (BCVA) were retrospectively compared between the 2 groups. RESULTS: Anatomic closure after surgery was achieved in 11 eyes (78.6%) in the ILM without peeling group and in 12 eyes (92.3%) in the ILM with peeling group (p = 0.596). The BCVA improved from 0.41 +/- 0.31 (log MAR) to 0.33 +/- 0.21 in the ILM without peeling group (p = 0.479) and from 0.46 +/- 0.41 (log MAR) to 0.28 +/- 0.25 in the ILM with peeling group (p = 0.001). CONCLUSIONS: ILM peeling with the addition of ERM peeling is an effective technique for BCVA improvement in the ERM with pseudolamellar macular hole. Vitrectomy, ERM peeling, gas tamponade, and ILM peeling are important for anatomic and functional success in the ERM with pseudolamellar macular hole.

BACKGROUND: Carpal tunnel syndrome (CTS) is the most common mononeuropathy encountered in clinical practice. When performing routine diagnostic nerve conduction studies (NCS) in patients with CTS, we sometimes happen to be confronted with patients who have no definite electrophysiological evidence of CTS. We therefore evaluated the diag-nostic sensitivities of several parameters in NCS for CTS patients. METHODS: We analyzed 187 patients (262 hands) who were diagnosed with CTS clinically and electrophysiologically for the past 4 years in this hospital. RESULTS: Significant abnormal findings of nerve conduction velocity (NCV) were noted in the palm to wrist (P-W) seg-ment( 98.5%), thumb-wrist (I-W) segment (97.3%), distoproximal ratio in the third finger (95.0%), and the terminal latency (71.4%) of the median nerve. There were no statistical differences in the abnormal NCVs between the male and female groups. The sensitivity of each compartment parameters were obtained in the female groups and statistical dif-ferences were found in the sensory NCV of the P-W segment and compound nerve action potential (CNAP) amplitude of the I-W segments in patients between the ages of 40 and 60. The sensory NCV of the P-W segment was especially more significant in this age group. There were statistical differences in the amplitude of the index finger to wrist (F-W) and P-W segments between the denervated electromyography group and normal group (p < 0.05). CONCLUSIONS: In clini-cally suspected CTS, the most sensitive tests were the sensory NCV of the P-W segment, I-W segment, and distoproxi-mal ratio in the third finger. Therefore, the sensory NCV of the P-W segment should be performed first. If the results of this test are unremarkable, then, the next tests should include the sensory NCV of the I-W segment and the distoproxi-mal ratio should be performed before ruling out the diagnosis of CTS.

A 35-yr-old woman carrying a 17-week-old fetus presented with right hydronephrosis and a single umbilical artery. Karyotyping was normal and targeted ultrasonography showed an otherwise normal fetus. After 28 weeks of gestation, the mother felt rapid, repetitive fetal movement and an ultrasound at 30 weeks of gestation revealed tonic clonic movements of the fetal trunk and extremities. At 36 weeks of gestation, an emergency repeat Cesarean section was performed because of a premature rupture of the membranes and a male infant weighing 4,295 gm was delivered. After birth, the infant continued to have movements suggestive of a generalized tonic clonic seizure. Brain computed tomography and magnetic resonance imaging revealed normal structures and an electroencephalography showed generalized suppression. Treatment with phenobarbital resulted in substantial improvement in the number of seizure episodes, however fine seizure-like movement continued in both of the hands, feet and in the tongue until the five-month follow-up. This is the first Korean report of a fetal seizure being diagnosed during the prenatal period.

Cervical pregnancy is a rare form of ectopic gestation in which the blastocyst implants in the cervical mucosa below the histologic cervical os. Because of the serious vaginal bleeding, hysterectomy was usually done in the management of cervical pregnancy. Howerver, conservative treatment is desirable for women who want to be pregnancy in the future. Methotrexate has been utilized recently for conservative management of cervical pregnancy. We report a case of cervical pregnancy which was treated succesfully with intramuscular methotrexate injection.

An isolated pyogenic pancreatic abscess (IPPA) without pancreatitis is extremely rare but can occur in patients with uncontrolled diabetes. This pathologic condition poses a clinical challenge in diagnosis and management because it can be confused easily with a malignancy. Endoscopic ultrasound (EUS) may be a useful diagnostic modality for indeterminate pancreatic lesions and IPPA. Here, we report two cases with elevated carbohydrate antigen 19-9 levels and pancreatic masses on cross sectional imaging. The patients were subsequently diagnosed with IPPA by EUS. EUS-guided drainage was performed successfully and the patients' clinical symptoms and radiologic findings improved. In our experience, EUS and EUS-guided drainage are crucial steps for the diagnosis and management of patients with an indeterminate pancreatic lesion. In addition, EUS-guided drainage has excellent technical and clinical outcomes for the treatment of IPPA.
