BACKGROUND: Nummular eczema, known as nummular dermatitis or discoid eczema, is an idiopathic disease that manifests coin-shaped, circular, or oval-shaped plaques with definite margins. These plaques can be exudative, erythematous, or edematous. The plaques are composed of tiny vesicles in the early stage, and later tend to be more scaly, dry, lichenified and thickened. It is a chronic condition which exhibits long periods of recurrence and relapse, plus changes depending on environmental conditions. For example, it is known that the eczema worsens in low humidity, or during winter. OBJECTIVE: Since there has been an absence of studies conducted since the 1970's, we investigated epidemiology, etiology, aggravation factors, family and past history, associated diseases such as atopic dermatitis, clinical menifestations, laboratory abnormalities, and course and prognosis with statistical analysis. METHOD: A total of 211 individuals, who had visited the Department of Dermatology, Kyungpook National University Hospital in Daegu, Korea between 2000-2004 with a diagnosis of nummular eczema, were selected. The data was based on a retrospective survey of hospital records. However, whenever the information was lacking, we called patients to ask lists of questions for this investigation. To clarify the prognosis and course of nummular dermatitis, we classified the course of the disease into 5 groups; "healed" (cleared completely), "almost healed" (more than 90% cleared), "improved" (from 50 to 90% cleared), "stationary" (less than 50% improvement), and "wax & waned" (repetitive recurrence). RESULTS: The male to female distribution showed about a 1.4-fold predominance for males. The onset of the disease in patients was often in their twenties, which correlated with previous reports which noted that onset of lesions in patients occurred in their twenties and sixties. Nummular eczema was most frequently aggravated in summer. Thirty five of the 211 patients had atopic dermatitis, and 53 had dry skin. Thirty five of 103 patients showed an elevated serum Ig E level (more than 250 IU/ml). Seventeen of 120 patients had an elevated eosiophil count (more than 7%). If the patients had had the eczema for a short duration, these seemed to be a better chance of the condition healing. CONCLUSION: This investigation is expected to help understand and obtain more information on nummular eczema.

To investigate the infection status of zoonotic trematode metacercariae in yellowfin goby, Acanthogobius flavimanus, from coastal areas of the Republic of Korea (Korea), we examined total 344 gobies from 21 localities with an artificial digestion method from 2013 to 2017. The metacercariae of Stictodora lari were most frequently detected in 45.3% goby from 7 localities, i.e., Taean-gun (Chungcheongnam-do), Gochang-gun (Jeollabuk-do), Muan-gun, Shinan-gun, Haenam-gun (Jeollanam-do), Hadong-gun and Goseong-gun (Gyeongsangnam-do). Their infection rates were 90.0%, 66.7%, 46.7%, 8.0%, 3.3%, 26.7%, and 86.7% and intensities were 1,090, 6.2, 1.6 1.0, 2.0, 2.0, and 7.2 metacercariae per fish infected respectively. Heterophyopsis continua metacercariae were found in 38.2% goby from 6 localities, i.e., Gochang-gun, Muan-gun, Shinan-gun, Gangjin-gun, Boseong-gun (Jeollanam-do) and Goseong-gun, and their intensities were relatively low, 1–21 metacercariae. Stictodora fuscata metacercariae were detected in 61.3% goby from 4 localities, i.e., Taean-gun, Gochang-gun, Hadong-gun and Goseong-gun. Their infection rates were 90.0%, 53.3%, 5.9%, and 73.3% and intensities were 1,081, 3.1, 3.0, and 10.2 metacercariae per fish infected respectively. Heterophyes nocens metacercariae were found in 55.0% goby from Muan-gun and Shinan-gun. Total 3 metacercariae of Isthmiophora hortensis were detected in 2 (8.0%) gobies from Shinan-gun. Total 15 metacercariae of Centrocestus armatus were detected in 5 gobies (33.3%) from Gyeongpo-ho (ho means lake) in Gangneung-si, Gangwon-do. The present study suggests that yellowfin goby, A. flavimanus, acts as the infection sources of zoonotic intestinal flukes in western and southern coastal areas than in eastern coastal areas of Korea.

Mycophenolate mofetil(MMF) is a new immunosuppressant which non-competitively and reversibly blocks the de novo synthesis of guanine nucleotides required for DNA and RNA synthesis during lymphocyte proliferation. So MMF selectively inhibits lymphocyte proliferation and it has less side-effects than other immunosuppressants. We described 2 cases of generalized pustular psoriasis improved with MMF. We administered MMF combined with cyclosporin in case 1 and acitretin in case 2. Both patients markedly improved with MMF administration 3 days after and had no severe side-effects. Thus the authors thought that MMF appears to be an effective therapeutic alternative in the treatment of generalized pustular psoriasis.

The infection status of freshwater fish with digenetic trematode metacercariae was examined in water systems of Hantangang and Imjingang (River), the Republic of Korea. A total of 877 (594 from Hantangang and 283 from Imjingang) fishes were examined by the artificial digestion methods. Clonorchis sinensis metacercariae were detected in 7 (1.2%) fishes (in 3 spp.) from Hantangang in Cheorwon-gun, Gangwon-do, and 40 (14.1%) fishes (in 7 spp.) from Munsancheon in Paju-si, Gyeonggi-do. The average densities were 1.9 and 35.6 per fish infected, respectively. Metagonimus spp. metacercariae were detected in 312 (52.5%) and 113 (39.9%) fishes from Hantangang and Imjingang, and their average densities were 47.5 and 9.6 per fish infected, respectively. Centrocestus armatus metacercariae were found in 161 (27.1%) and 70 (24.7%) fishes from Hantangang and Imjingang, and their average number per fish infected was 694 and 82, respectively. Echinostoma spp. metacercariae were detected in 50 (8.4%) and 94 (33.2%) fishes from Hantangang and Imjingang, and their average densities were 9.6 and 23.1 per fish infected, respectively. The infection status of fishes with metacercariae of Stephanoprora spp., Diplostomum spp., Clinostomum complanatum, Metorchis orientalis, and Metorchis taiwanensis were analyzed by surveyed regions. Conclusively, it was confirmed that C. sinensis metacercariae were quite commonly detected in fishes from Munsancheon but rarely from other localities, whereas the metacercariae of other digenetic trematodes were relatively prevalent in fishes from water systems of Hantangang and Imjingang in Korea.

The infection status of zoonotic trematode metacercariae was investigated in a total of 2,293 freshwater fish collected from 11 rivers or streams in 9 administrative regions of Gangwon-do, Korea for 5 years (2009-2013). All fish were collected by netting methods and examined using the artificial digestion methods. Clonorchis sinensis metacercariae were detected in 4 fish species, i.e., Pungtungia herzi, Squalidus japonicus coreanus, Acheilognathus rhombeus, and Ladislabia taczanowskii, from only Hantangang in Cheorwon-gun. Metagonimus spp. metacercariae were found in 1,154 (50.3%) fish and their average number per infected fish was 55.8. Among the positive fish species, especially Tribolodon hakonensis from Namdaecheon in Yangyang-gun and Plecoglossus altivelis from Osipcheon in Samcheok-si were most heavily infected. Centrocestus armatus metacercariae were detected in 611 (26.7%) fish and the average metacercarial burden per infected fish was 1,032. Two chub species, Zacco platypus and Zacco temminckii were highly and heavily infected with C. armatus metacercariae in almost all regions surveyed. Echinostoma spp. metacercariae were also found in 24 fish from a few localities, but their numbers per fish infected were very low. From the above results, it is confirmed that the metacercariae of intestinal flukes, especially Metagonimus spp. and C. armatus, were heavily infected, while C. sinensis metacercariae were rarely found in fish from Gangwon-do, Korea.

Fibrous histiocytoma is a common benign tumor which occurs usually in the dermis. It can be classified as fibrous type, cellular type, mixed type and angiomatoid type, depending on its major cellular components. Angiomatoid fibrous histiocytoma is a rare subtype, showing characteristic hemorrhagic cyst. Fibrous histiocytoma arises rarely in deep soft tissues such as fascia, muscle or periosteum, and shows clinical and histopathological characteristics somewhat different from the cutaneous histiocytoma. We report a case of angiomatoid fibrous histiocytoma of deep location which arose in the galea of scalp in a 7-year-old boy, who had a tender slightly fixed deep seated nodule, measuring 0.5 cm, for 5 months.

PURPOSE: To investigate the effects of phacoemulsification in glaucomatous eyes with a functioning Ahmed glaucoma valve insertion. METHODS: This retrospective analysis followed 28 eyes from 26 patients with a functioning Ahmed glaucoma valve who had clear corneal phacoemulsification from December 1999 to February 2006. Intraocular pressure (IOP), best corrected visual acuity (BCVA), number of glaucoma medications and additional glaucoma surgeries were measured. RESULTS: The mean IOP before phacoemulsification was 17.4 mmHg +/- 5.8 (SD). Postoperative IOP was 13.6 +/- 4.4 mmHg, 13.7 +/- 4.0 mmHg, 14.1 +/- 4.0 mmHg and 15.4 +/- 3.8 mmHg at 1, 2, 6, and 12 months, respectively. The change in the number of glaucoma medications significantly changed at 1 month (p<0.05), but did not change at 2, 6 and 12 months (p>0.05) postoperatively. The IOP significantly changed at 1 week, 1 month, 2 months, and 6 months (p<0.05), but did not significantly change at 12 months (p>0.05) postoperatively. No eyes required additional surgery. BCVA improved in 23 eyes; the mean improvement was 3.7 +/- 2.9 Snellen lines at 2 months postoperatively. CONCLUSIONS: Phacoemulsification in glaucomatous eyes with a functioning Ahmed glaucoma valve improved BCVA and maintained control of IOP.

A 36-year-old woman with an unremarkable medical history presented for laparoscopic cholecystectomy. Routine preoperative assessment of the patient's airway revealed normal jaw opening. Upon induction of anesthesia, her jaw locked in a nearly closed position. X-ray and MRI of the temporomandibular joints that were taken postoperatively showed normal findings except for the steeper posterior angles of the articular eminences. During the next induction of anesthesia, intubation was readily accomplished by opening the mandible with a forward pulling of the chin.
