PURPOSE: Percutaneous needle aspiration biopsy under the imaging guidance in the diagnosis of intrathoracic diseases has become a standard practice. Core tissue obtained by automated gun biopsy(AGB) is believed to be more diagnostic than materials from fine needle aspiration(FNA) by many cytopathologists. The authors evauated the role of automated gun biopsy in localized pulmonary lesions with respect to the its accuracy and complications. MATERIALS AND METHODS: We performed 107 percutaneous biopsies in localized pulmonary lesions under fluoroscopic guidance among 107 patients:AGB using 18G or 20G was done in 81 patients, and both AGB and FNA was done in 26 patients. RESULTS: Biopsy samples sufficient for histologic diagnosis were obtained in 94(87.9%) of 107 patients, AG8 in 73(90.1%) of 81 patients and AGB and FNA in 21(80.8%) of 26 patients. 11 of 13 negative results were due to inadeguate specimen size for the histologic diagnosis or were composed of necrotic areas, and 2 of 13 negative results were obtained through nontarget tissue. 10 patients developed pneumothorax and 4 of them required chest tube insertion. Minimal hemoptysis was found in 3 patients. CONCLUSION: Percutaneous automated gun biopsy under fluoroscopic guidance was easy and simple method of obtaining specimens of good quality and quantity. It may be an useful procedure in the diagnosis of localized pulmonary lesions.

PURPOSE: To report a case of herpes simplex keratitis after descemet stripping automated endothelial keratoplasty (DSAEK). CASE SUMMARY: A 66-year-old male underwent DSAEK in his right eye due to bullous keratopathy after cataract surgery. The corneal epithelium which was removed during surgery was healed, but the patient was experiencing pain and decreased visual acuity in his right eye 1 month after surgery. Increasing corneal epithelial defects and corneal edema were observed on slit-lamp examination. Therapeutic soft contact lenses and artificial tears were used for treatment but were not effective, thus amniotic membrane transplantation was performed. Three months after transplantation, the epithelial defect appeared as a geographic ulcer suspecting to be herpes simplex keratitis; therefore, ganciclovir ophthalmic ointment and oral acyclovir were administered. Six months after antiviral therapy, the epithelial lesion of herpes simplex keratitis completely disappeared, leaving only mild corneal opacity. CONCLUSIONS: If corneal epithelial defects are persistent after DSAEK in patients even with no past history of herpes simplex keratitis, herpes simplex keratitis should be considered in the differential diagnosis.

Posterior reversible encephalopathy syndrome (PRES) is a newly described adverse effect possibly associated with gonadotropin-releasing hormone (GnRH) agonist therapy. We report a case of PRES after 2 doses of depot GnRH agonists in a 44-year-old woman with a huge myoma uteri and iron-deficiency anemia. Brain magnetic resonance imaging showed high signal lesions in both occipital lobes on fluid-attenuated inversion-recovery (FLAIR) images, compatible with PRES. After treatment with anticonvulsant, she recovered both radiographically and clinically. The association between PRES and GnRH agonist use is still enigmatic, and thus should be further clarified.

Gastrectomy or vagotomy may result in reactive hypoglycemia, which, in some cases, can reduce the plasma glucose levels to 30~40 mg/dL due to rapid digestion and absorption of food, especially carbohydrate. We treated the patient with frequent episode of severe hypoglycemia. Reactive hypoglycemia is caused by an excessive insulin secretion after a sharp rise in plasma glucose. He had undergone total gastrectomy due to stomach cancer 4 years before. Since nutritional treatment did not successfully manage his reactive hypoglycemia, an alpha-glucosidase inhibitor, voglibose was administered. His hypoglycemic symptoms disappeared and a rapid change of plasma glucose and insulin levels were attenuated after the alpha-glucosidase inhibitor treatment. The effects of alpha-glucosidase inhibitor were documented in a 5-hour oral glucose tolerance test, where not only insulin and C-peptide rise was clearly attenuated, but also the blood glucose concentration did not fall low enough to induce hypoglycemic symptoms. This therapy was very effective and the patient has not had any recurrence of reactive hypoglycemia since the initiation of the therapy.

OBJECTIVE: To report an efficacy of gonadotropin releasing hormone (GnRH) antagonist administration after freezing of all embryos for treatment of early type ovarian hyperstimulation syndrome (OHSS). METHODS: In 10 women who developed fulminant early type OHSS after freezing of all embryos, GnRH antagonist (cetrorelix 0.25 mg per day) was started at the time of hospitalization and continued for 2 to 4 days. Fluid therapy and drainage of ascites was performed as usual. RESULTS: Early type OHSS was successfully treated without any complication. At hospitalization, the median (95% confidence interval [CI]) of the right and the left ovarian diameter was 10.0 cm (7.6 to 12.9 cm) and 8.5 cm (7.5 to 12.6 cm). After completion of GnRH antagonist administration, it was decreased to 7.4 cm (6.2 to 10.7 cm) (P=0.028) and 7.8 cm (5.7 to 12.2 cm) (P=0.116), respectively. The median duration of hospital stay was 6 days (3 to 11 days). Trans-abdominal drainage of ascites was performed in 2 women and drainage of ascites by percutaneous indwelling catheter was performed in 4 women. No side effect of GnRH antagonist was noted. CONCLUSION: GnRH antagonist administration appears to be safe and effective for women with fulminant early type OHSS after freezing all embryos. Optimal dose or duration of GnRH antagonist should be further determined.

Growth hormone (GH) has been available for more than 4 decades for the treatment of GH deficiency. But mass production of recombinant DNA growth hormone has made GH therapy widely available for children with no GH deficiency. The use of GH therapy in children has resulted in adverse effects ranging from minor disturbances such as edema and injection site reactions to more significant, but rare events such as benign intracranial hypertension and slipped capital femoral epiphysis. Yet there has been no report in the dermatological field on skin adverse effects associated with GH therapy. We report here on 2 cases of psoriasis following GH therapy in children.

PURPOSE: As one of the new chemotherapeutic agents, gemcitabine is widely used as a four-week schedule in combination with cisplatin in the treatment of advanced non-small-cell lung cancer (NSCLC). In this study, we evaluated the efficacy, tolerance, and survival effect of this combination in a three-week schedule in patients with locally advanced inoperable or metastatic NSCLC. MATERIALS AND METHODS: Between January 2000 and September 2002, previously untreated 124 NSCLC patients were enrolled and 118 patients, who completed at least two cycles of chemotherapy, were evaluated. Patients received gemcitabine 1200 mg/m2 on days 1 and 8, cisplatin 75 mg/m2 on day 1 of a 21-day cycle, for a maximum of 6 cycles. RESULTS: They were 81 men and 37 women. Clinical stage IIIB was present in 56 (47.5%), and stage IV in 62 (52.4%) patients. Sixty-seven patients (56.8%) had a performance status of ECOG grade 0 or 1 and fifty-one patients (43.2%) of grade 2. During the period of chemotherapy, grade 3/4 leukopenia and neutropenia were observed in 19.5% and 31.4%, respectively and grade 3/4 thrombocytopenia in 7.6%. The overall response rate was 52.5% among the 118 patients. Overall median survival time was 12.2 months, and one-year and two-year survival rates were 50.2% and 20.4% respectively. The presence of response to chemotherapy, ECOG performance status of grade 0~1, and women showed better survival by the univariate analysis (p=0.010, 0.001 and 0.015, respectively). CONCLUSION: A three weekly gemcitabine/cisplatin doublet was relatively well tolerated, with an acceptable response rate and a reasonable median survival in locally advanced inoperable or metastatic NSCLC.
