The fine needle aspiration biopsy has been utilized as a diagnostic method for numbers of orbital disorders. This biopsy has been found particularly valuable in the diagnosis of orbital metastatic tumor of malignant nature which may be hard to confirm by ultrasound. CT or other non-invasive tests. For performing fine needle aspiration biopsy, a syringe holder (pistol) has been in common use, however, which was markedly inconvenient III small orbital tumors because of handling difficulties. Accordingly, authors performed fine needle aspiration biopsy on an acute leukemic patient who showed enlargement of lacrimal galnd with 23G, 3/4inch scalp needle. The scalp needle was quite easy to handle, and aspirated material could be readily subjected to inject to slide glass for smear. Thus fine needle aspiration biopsy with scalp needle seems to be useful method in the diagnosis of anterior orbital disorders.

We have investigated the changes of DNA ploidy and S-phase fraction in proliferative lesions of rat liver. Proliferative lesions were induced by diethylnitrosamine and partial hepatectomy. DNA ploidy was measured by flow cytometer, and S-phase fraction was measured by in situ bromodeoxyuridine(BRdU)-anti BRdU monoclonal antibody techniques. Normal liver and initiated lesion revealed DNA diploidy or DNA tetraploidy. Hepatocyte nodule (NODULE) and hepatocelular carcinoma (HCC) revealed DNA diploidy, tetraploidy or aneuploidy. S-phase fraction was 1.0+/-0.9, 1.0+/-0.9m 3.7+/-2.3, 5.5+/-4.9, and 13.8+/-11.6 in normal liver, initiated lesion, NODULE not associated with HCC, NODULE associated with HCC, and HCC, respectively. In NODULE associated with HCC, it was widely distributed, ranging from 0.8 to 15.5%. In conclusion, S-phase fraction appeared to be increased as the hepatocarcinogenesis proceeded, but DNA ploidy did not. There was a heterogeneity of DNA ploidy and S-phase fraction in the proliferative hepatic lesions.

The schwannoma is a benign neoplasm originating from Schwann cell. Solitary nerve sheath tumors such as benign schwannomas arising in the pelvic retroperitoneum are infrequently reported. Those tumors can indeed be misdiagnosed for other more common conditions both clinically and instrumentally. We report a very rare case of a benign retroperitoneal pelvic schwannoma of the obturator fossa, which was incidentally found and misdiagnosed as adnexal mass preoperatively in fifty one-years-old postmenopausal women.

PURPOSE: Avellino corneal dystrophy (ACD) is the most common form of inherited corneal disorder in Korea. To report 4 cases of ACD concurrent with floppy eyelid syndrome (FES), which had not been previously reported, and to find an additional mutation. METHODS: Five patient in 2 families who were diagnosed as ACD patient were examined whether they had FES. PCR, cold-SSCP and sequencing analysis were performed for identification of genetic defect. RESULTS: Four of 5 ACD patients showed FES which characterized by easily everted eyelid and conjunctival papillary reaction. In one family, succeeding two generations had this feature. We identified R124H mutation in all 5 ACD patients, however, no additional mutation wsa identified in BIGH3 gene. CONCLUSIONS: One case series suggested that there may be some linkage between the genes responsible for ACD and FES.

PURPOSE: Laparoscopic gastrectomy is accepted as a standard treatment for patients with early gastric cancer in Korea, Japan, and China. However, duodenal stump leakage remains a fatal complication after gastrectomy. We conducted a prospective phase II study to evaluate the safety of the new technique of laparoscopic reinforcement suture (LARS) on the duodenal stump. MATERIALS AND METHODS: The estimated number of patients required for this study was 100 for a period of 18 months. Inclusion criteria were histologically proven gastric adenocarcinoma treated with laparoscopic distal or total gastrectomy and Billroth II or Roux-en-Y reconstruction. The primary endpoint was the incidence of duodenal stump leakage within the first 30 postoperative days. The secondary endpoints were early postoperative outcomes until discharge. RESULTS: One hundred patients were enrolled between February 2016 and March 2017. The study groups consisted of 65 male and 35 female patients with a mean age (years) of 62.3. Of these, 63 (63%) patients had comorbidities. The mean number of retrieved lymph nodes was 38. The mean operation time was 145 minutes including 7.8 minutes of mean LARS time. There was no occurrence of duodenal stump leakage. Thirteen complications occurred, with one case of reoperation for splenic artery rupture and one case of mortality. CONCLUSIONS: Based on the results of this prospective phase II study, LARS can be safely performed in a short operation period without development of duodenal stump leakage. A future randomized prospective controlled trial is required to confirm the surgical benefit of LARS compared to non-LARS.

PURPOSE: Chromomycetes is a plant parasite and one of the pigmented filamentous fungi, which rarely causes human infection. The authors report the first case of fungal keratitis caused by chromomycetes in korea. METHODS: A 65-year-old woman developed pain, redness, and an yellowish-brown infiltrate in her right eye. She had a history of corneal scratch by a pumpkin stalk and transferred by a local clinic after management for about 1 months. The clinical features suggested fungal keratitis, and the patient was undertaken surgical debridement with amniotic membrane graft and treated with oral terbinafine with natamycin and amphotericin B eyedrops. Surgically taken biopsy specimen was cultured. Amniotic membrane was removed after 1 week. After slight improvement of symptom, necrotizing ulceration was enlarged in spite of continuous antifungal therapy. Lamellar keratoplasty with amniotic membrane graft was done with antifungal therapy. Systemic agent was changed to fluconazole. Clinical improvement was achieved after about 2 months. The fungus was identified as Fonsecaea pedrosoi. RESULTS: Fungal keratitis was successfully treated with antifungal medication combined with amniotic membrane graft. CONCLUSIONS: This is a rare case of infectious keratitis caused by chromomycetes. But its clinical course was severe, so exact culture and identification following aggressive surgical and medical treatment was needed.

Dehydroevodiamine (DHED) is one of the bioactive components of the Chinese herbal medicine Wu-chu-yu-tang that has been shown to produce various pharmacological effects. In the present study, we investigated the pharmacokinetics of DHED after intravenous administration of two doses (2.5 and 5 mg/kg) in anesthetized rats. The plasma concentration of DHED was measured by reverse-phase high-performance liquid chromatography with UV detection. The mean area under the curve of the time-concentration profile was 21.9 and 53.9 microgram-min/ml after the 2.5- and 5-mg/kg doses, respectively, and the volume of distribution was 1584.9 and 1580.6 ml following 2.5- and 5-mg/kg doses, respectively. Plasma concentration profiles versus time were compatible with a two-compartment model and first-order kinetics. The terminal elimination half-life was 91.8+/-16.6 min and 78.7+/-11.9 min in the dose of 2.5 and 5 mg/kg, respectively. This is the first report to study the pharmacokinetics of DHED in animals.

Abnormalities of body fluid and electrolyte balance, acute renal failure, nephrotic syndrome, interstitial nephritis and papillary necrosis are well known disease of wide spectrum of NSAID induced renal side effect. Many different mechanism such as inhibition of prostaglandin pathway, delayed hypersensitivity reaction and direct toxicity are reported to relate to development of disease. Recently, overuse of NSAID has steadily increased the cases of NSAID induced side effects and in some cases permanent damage to kidney has been reported. Authors experienced a 67-year-old male patient who presented with gross hematuria, edema and azotemia and diagnosed as interstitial nephritis accompanying nephrotic syndrome. Kidney biopsy shows the edema and the diffuse infiltration of lymphocytes in the interstitium. The glomerular changes suggest minimal change lesion or focal segmental glomerular sclerosis in early stage. The patient had continuously consumed piroxicam for 6 months and had improved after discontinuation of this drug as well as treatment with steroid but remained renal damage. This case suggest that piroxicam may be an agent that causes interstitial nephritis and nephrotic syndrome. Therefore clinician should use it with caution especially in patients with high risk factors.
