The purpose of the present study is to demonstrate the distribution of carbonic anhydrase pattern in the various termatodes (Fasciola gigantica, Paramphistoma orthocoelium, Paragonimus westermani) by means of Kurada staining method, and to correlate these findings with the histochemical data and harboring location. The results are summarized as follows: In Fasciloa gigantica, carbonic anhydrase activity was positive in the vitelline gland cells and eggs in the uterus. In Paramphistoma orthocoelium, carbonic anhydrase activity was positive in the vitelline gland cells and eggs in the uterus. In Paragonimus westermani, carbonic anhydrase activity was positive in intestinal mucous membrane, vitelline gland cells and eggs.

To identify significant prognostic factors in patients undergoing simple hysterectomy in the presence of invasive cervical cancer, the records of 45 patients who had taken such a procedure between 1993 and 1997 were reviewed. Overall relapse-free survival and 5-year survival rates were 91.1 and 92.1%, respectively. Factors found to be significantly related to survival were the retrospectively determined stage(p=0.0000), the presence of residual disease(p=0.0001), and cell type(p=0.0000). By multivariate analysis, factor emerging as significantly detrimental to survival was the cell type. The presence of residual disease was a marginally significant factor(p=0.067). The expectations for survival of patients with residual tumor mass and/or with adenocarcinoma after simple hysterectomy appear to be markedly worse than those with others, so radical reoperation should be considered in those patients.

Cutaneous metastases from internal carcinomas are relatively rare, especially from pancreatic carcinoma. Pancreatic carcinomas are usually adenocarcinomas which arise in the head of the gland, and are known to rapidly metastasize to the lymphatic system by permeation and embolization. We report a case of cutaneous metastasis from pancreatic adenocarcinoma. in 74-year-old male patient who have two pea sized, slight erythematous nodules on the lower abdomen and posterior side of the neck.

6.Systemic New Antifungal Agents.
Korean Journal of Medical Mycology 2003;8(4):147-156
Voriconazole is a second-generation triazole that has an enhanced antifungal spectrum, compared with older triazoles. It will likely become the drug of choice for treatment of invasive aspergillosis and many Scedosporium/Pseudallescheria and Fusarium infections. Voriconazole should not replace fluconazole or other antifungal agents for treatment of most Candida infections. The drug has more side effects and drug interactions than fluconazole. The oral formulation, with its excellent bioavailability, is available it is especially beneficial in patients with renal failure, who should not be exposed to the cyclodextrin vehicle used for the intravenous formulation. Caspofungin, the first inhibitor of fungal beta -1, 3 glucan synthesis, is effective for the treatment of mucosal and invasive candidiasis and invasive aspergillosis. It is also active in vitro and in animal models against a number of other filamentous and dimorphic endemic fungi and in animal models of Pneumocystis carinii infection. Caspofungin has an excellent safety profile. Caspofungin may prove to be useful in empirical therapy for suspected invasive fungal infections. Additional clinical trial data that expand our knowledge of the usefulness of caspofungin for these and other mycoses is anticipated. The broad spectrum antifungal itraconazole is an effective and well tolerated agent for the prophylaxis and treatment of systemic fungal infections. The recent development of an itraconazole oral solution and an intravenous itraconazole solution has increased the options for the use of this drug. Intravenous itraconazole solution is at least as effective as intravenous amphotericin B in the empirical treatment of neutropenic patients with systemic fungal infections, and drug-related adverse events are more frequent in patients treated with amphotericin B. A large proportion of patients with confirmed aspergillosis also respond to the treatment with intravenous itraconazole followed by oral itraconazole. Liposomal nystatin is another promising antifungal agent that might be effective for treatment of invasive candidiasis and invasive aspergillosis. More clinical data, however, is needed for clinical application.

The reduction of nasal bone fracture has been done by a simple procedure. The nasal bone fracture was not a serious problem and patients are usually treated as outpatients. However it is causing increased demand for medical services far cosmetic reasons. We studied the nasal bone fracture by retrospective analysis, it comprising 606 patients with nasal bone fractures in various accidents and treated of Chonnam University Hospital from March 1995 to February 1998. We reviewed and analyzed the medical records and facial bone CT scans of 606 patients. The following results were obtained. 1. The prevalent age group was in the third decade, the most common cause was traffic accidents, while nasal swelling, tenderness, nasal deviation and crepitation were examined 2. The classification of nasal bone fracture was done by facial bone CT. Class 1: Nasal tip depressed fracture(16%) Class 2: Displaced nasal bone fracture without depression(30%) Class 3: Displaces nasal bone fracture with depression(12%) Class 4: Comminuted nasal bone fracture (10%) Class 5: Simple fracture of nasal bone and frontal process of maxilla(14%) Class 6: Comminuted fracture of nasal bone and frontal process of maxilla(11%) Class 7: Nasal bone fracture without displacement(9%) .

BACKGROUNDS: When measuring lung function and response to bronchodilator, MDI(metered-dose inhaler) is commonly used but unfamiliarity of its use and cold sensation by the puffed gas decrease reliability of the result. Spacer can reduce the cold freon effect and undesired oropharyngeal deposition caused by the rapid evaporation of the propellant and there are many studies which showed more effectiveness of spacer on the treatment of children with asthma but no study whether it is effective on the bronchodilator response test in the first medical examination of old age. Therefore, we tested whether the use of spacer can reduce the cold freon effect and improve the bronchodilator response in the first medical examination of old age. METHODS: Two hundred of elderly patients( 65years) who had never used MDI were measured the bronchodilator response. Subjects were randomised to either spacer-user or spacer-nonuser. Twenty minutes after 400 g fenoterol was administered, FEV1 (forced expiratory volume in one second) was measured. Bronchoconstriction was defined as a decrease in FEV1 by 10% or greater after bronchodilator inhalation. We further devided each group into normal or obstructive group, obstructive group was defined as FEV1<80% of predicted and FEV1/FVC<70%. RESULTS: In normal group, spacer-user(n=83) showed greater bronchodilator response than spacer-nonuser(n=66), 6.43% vs 3.81% respectively(p<0.05) and two case of bronchoconstriction occured only in spacer-nonuser. In obstructive group, there is no significant difference in bronchodilator response between spacer-user(n=18) and spacer-nonuser(n=33), 12.32% vs 11.16% respectively(p>0.05) but brochoconstriction(n=1) occured only in spacer-nonuser. CONCLUSION: Spacer improved bronchodilator response and prevented bronchoconstriction, in the first medical examination of old age.

10.A Case of Lateral Medullary Infarction after Endovascular Trapping of the Vertebral Artery Dissecting Aneurysm.
Journal of Korean Neurosurgical Society 2012;51(3):160-163
We report an unusual case of lateral medullary infarction after successful embolization of the vertebral artery dissecting aneurysm (VADA). A 49-year-old man who had no noteworthy previous medical history was admitted to our hospital with a severe headache. Computed tomography (CT) revealed a subarachnoid hemorrhage, located in the basal cistern and posterior fossa. Cerebral angiography showed a VADA, that did not involve the origin of the posterior inferior cerebellar artery (PICA). We treated this aneurysm via endovascular trapping of the vertebral artery distal to the PICA. After operation, CT revealed post-hemorrhagic hydrocephalus, which we resolved with a permanent ventriculoperitoneal shunt procedure. Postoperatively, the patient experienced transient mild hoarsness and dysphagia. Magnetic resonance image (MRI) showed a small infarction in the right side of the medulla. The patient recovered well, though he still had some residual symptom of dysphagia at discharge. Such an event is uncommon but can be a major clinical concern. Further investigation to reveal risk factors and/or causative mechanisms for the medullary infarction after successful endovascular trapping of the VADA are sorely needed, to minimize such a complication.
