The intra-articular osteochondroma arising from soft tissue is very rare and has been reported less than a dozen cases in the English literature. This tumor is the result of extrasynovial metaplasia of the fibrous capsule or of the adjacent connective tissue of a joint. The authors experienced a case of giant intra-articular osteochondroma of the right knee in a 37 year-old man which arised from the medial meniscus. Histology as well as gross findings were consistent with osteochondroma. Excision of the mass with attached meniscus relieved symptoms. No recurrence, or malignant change was identified up to 1 year after excision.

Four cases of newborn with tension pneumothorax induced by a conventional ventilator were admitted to our nursery from January 1. 1992 to June 30. 1992 and they were managed by high frequency ventilator (Infrasonic Infant Star Ventilator). In contrast, four cases of newborn with tension pneumothorax who were continuously on the conventional ventilator, were included as a control group. They were admitted to our nursery from July 1. 1991 to december 31. 1991 and they were managed by conventional ventilator with conservative treatment. 1) In the control group, who were continuously managed by the conventional ventilator after thoracostomy with water seal drainage, we changed ventilator setting appropriately in control group but they had poor arterial blood gas analysis. The arterial blood gas analysis within 24hr/within 72hr in control group were pH 7.192/7.195, Paco2 72.15/82.25, PaO2 78.92/83.875, HCO3-26.975/27.925 and conventional ventilator care did not show any definite benefit for improvement of arterial blood gas analysis and tension pneumothorax as well. 2) Two cases in control group expired on the 6th day of thoracostomy without any resolution of tension pneumothorax. 3) In contrast, four cases with tension pneumothorax managed by high frequency ventilator were improved. Tension pneumothorax and arterial blood gas analysis to normalize from 6hr of high frequency ventilation and four cases of tension pneumothorax were completely reabsorbed within 4days.

Laparoscopic distal gastrectomy for gastric cancer has rapidly gained popularity because of its short-term benefits, including less blood loss, less postoperative pain, earlier postoperative recovery, and shorter hospital stay, compared to the conventional open method. Although the long-term results of phase III trials have yet to be published, laparoscopic distal gastrectomy is now considered to be accepted for early-stage gastric cancer. As advances in instruments and the accumulation of laparoscopic experience increase, laparoscopic distal gastrectomy is being used for advanced gastric cancer. However, due to the technical difficulty of performing D2 lymphadenectomy, this application remains controversial. Well-designed clinical trials will clarify the surgical feasibility and oncological safety of laparoscopic distal gastrectomy for advanced gastric cancer in the near future.

188Re (beta=22 MeV; gamma=155 keV; T1/2=16.9 hours) is an attractive therapeutic radioisotope which is produced from decay of reactor-produced tungsten-188 parent (T1/2=69 days). 188W has been produced from the double neutron capture reaction of 186W. 188Re can be easily obtained by elution of saline on alumina based 186W/188Re generator, which is commercially available. Complexes labelled with 188Re have been developed for the radiotherapy treatment of diseases because of the desirable nuclear properties of the radioisotope and it's chemical properties similar to those of technetium, a well established diagnostic agent.

Ovarian carcinoma usually metastasizes to the peritoneal cavity and the regional lymph nodes. While the peritoneal metastases if often widespread, metastases beyond the peritoneal cavity including axillary lymph nodes are uncommon. A recurrence of ovarian carcinoma in only the axillary lymph node is also a rare case. We report here on an axillary lymphatic metastasis as a result of recurrence of ovarian carcinoma in a 43-yr-old woman. Six years after the initial operation for ovarian carcinoma, multiple lymphatic metastases in the right axilla were noted as a palpable axillary masses. There are few previous reports about ovarian carcinoma that metastatized to the axillary lymph nodes. It must be differentiated from breast carcinoma because the treatment and prognosis of metastatic ovarian carcinoma differ from those of primary breast carcinoma.

PURPOSE: To evaluate the efficacy and safety of brinzolamide 1%/brimonidine 0.2% fixed combination (BBFC) in normal tension glaucoma (NTG) patients. METHODS: This prospective study included patients treated with brinzolamide 1% monotherapy, brimonidine 0.2% monotherapy or brinzolamide 1% and brimonidine 0.2% concomitant therapy, as well as newly diagnosed NTG patients. The enrolled patients who used brinzolamide 1% or brimonidine 0.2% switched to BBFC and newly diagnosed NTG patients were treated with BBFC. The patients receiving brinzolamide 1% or brimonidine 0.2% monotherapy or brinzolamide 1% and brimonidine 0.2% concomitant therapy switched antiglaucoma drugs to BBFC. Newly diagnosed NTG patients used BBFC as the first therapy. The study consisted of 1 screening/baseline visit and 3 follow-up visits conducted after 1, 4, 8, 12 and 24 weeks of treatment. Intraocular pressure (IOP), mean deviation value and adverse drug reactions were evaluated before treatment and after treatment with BBFC. RESULTS: The mean IOP in the brinzolamide 1% monotherapy group was 13.5 ± 1.6 mm Hg and the mean IOP after switched from brinzolamide 1% monotherapy to BBFC was 12.1 ± 1.5 mm Hg. The mean IOP in the brimonidine 0.2% monotherapy group was 14.2 ± 1.3 mm Hg and the mean IOP after switched from brimonidine 0.2% monotherapy to BBFC was 11.7 ± 1.5 mm Hg. The mean IOP was 11.9 ± 2.1 mm Hg in the brinzolamide 1% and brimonidine 0.2% concomitant therapy group and the mean IOP after switched from brinzolamide 1% and brimonidine 0.2% concomitant therapy to BBFC was 12.0 ± 1.1 mm Hg. The mean IOP and reduction rate were 10.7 ± 2.1 mm Hg and 35.5%, respectively,in the newly diagnosed NTG patients treated with BBFC. There was no serious adverse drug reaction causing ocular damage. CONCLUSIONS: BBFC provides a significant IOP reduction and is a safe antiglaucoma medication for NTG patients.
