Various methods have been used on patients with skeletal Class II division 1 malocclusion. The activator, Frankel appliance, headgear, Herbst appliance, and Twin-block appliance are some examples. The ideal treatment effect using these appliances would be to inhibit horizontal and vertical growth of the maxilla while promoting mandibular growth and obtaining optimum dentition. The Teuscher appliance has a simultaneous combined headgear effect with maxillary growth inhibition and an activator effect with mandibular growth promotion. The purpose of this study was to examine how well these effects were clinically obtained and the results are as follows. 1. The forward growth of the maxilla was effectively inhibited. 2. The downward-forward growth of the maxillary dentoalveolar complex was inhibited. 3. Growth promotion of the mandible was not observed. 4. The overjet, overbite, molar key were effectively improved. 5. The protruded upper lip and facial profile were improved.

Cysticercosis, like other parasitic disease, is still endemic in many parts of the world, and is not infrequently found in Korea. The authors reviewed CT findings of 54 cases of the cysticercosis involving the centralnervous system which were proven by pathology and clinical findings. The resuls are as follows; 1. Male to femaleratio is 3:1 and the most prevalent age group is the fifth decade. The most common symptom is seizure(56%). 2.Involved areas in the brain are parenchymal (66%), intraventricular (15%), leptomeningeal (40%) and the mixed(15%). 3. Pre-contrast CT findings are the round low density in 46 cases (85%), multiple pin-point calcificationin 18 cases (33%), variable degrees of hydrocephalus in 20 cases (37%) and peripheral edmatous change in 8 cases(15%). 4.

PURPOSE: Many reliable articles on the effectiveness of alpha blockers have been published. Evidence-based diagnostic guidelines and therapeutic guidelines for benign prostatic hypertrophy (BPH), which is one of the most common urological diseases, have been proposed in many foreign countries. This paper examines the efficacy of alpha blocker, a common therapeutic drug for BPH, in Korean patients through meta-analysis. MATERIALS AND METHODS: From 1993 to 2001, the term 'BPH' and alpha blocker for BPH were used as key words to search for related articles in the Medical Research Information Center, the National Assembly Library of the Republic of Korea, the Korean Journal of Andrology and the Korean Journal of Urology. A total of 10 articles were selected as being suitable for evaluation and these articles were ranked with levels ranging from I to V, where level I indicated a large randomized controlled trial and level V indicated a non-controlled case accumulation study. RESULTS: There were improvements for the symptom score (45.3%), and for the maximum urinary flow rate (36.0%). The reasons for patient drop-outs were follow-up loss for 60%, drug side effects for 11%, and ineffectiveness of drug for 6.8%. The common side effects were dizziness (4.2%), orthostatic hypotension (2.2%), and headache (1.7%). The blood pressure was sustained in the normotensive patients, wheareas BP showed a tendency to be reduced in hypertensive patients. CONCLUSIONS: Treatment with alpha blocker resulted in the BPH patients in all the studies receiving sustained benefit. Yet most of these papers were short-term, non randomized case-accumulation studies. However, BPH is a chronic disease that may worsen over time. Therefore, evaluation of long term tolerability and efficacy of alpha blocker is necessary.

Double primary cancer is defined as the case of primary malignant tumors, which must be arise in different sites and have a different histologic appearences. The number of reported cases of double primary malignant tumors has increased in recent and the occurrence of multiple primary cancers in the same individuals is one of the interesting subjects for investigation and research in relation to the carcinogenic mechanism and/or genetic factors. We have experienced a case with double primary malignant tumors of different site origins such as stomach adenocarcinoma and rectal adenocarcinoma, which were diagnosed by biopsies with gastro and colono fiberscopy. For its great rarity, we report this case with review of literatures.

Intraosseous ganglion of the scaphoid associated with occult ganglion is rare. A 27-year-old man who presented with a 4-month history of progressive left wrist pain visited our institution. The patient was diagnosed intrasosseous ganglion of the carpal scaphoid assosiated with occult ganglion. We obtained satisfactory result by arthroscopic procedure and report this case focusing on surgical technique with literature review.

Enlow's counterpart analysis reflects the characteristics of each individual sample to find out the cause of the malocclusion and further applying them to the clinic. Enlow's counterpart analysis was performed on 100 Korean samples (50 male, 50 female) with normal occlusion and 100 skeletal class III patients (50 male, 50 female) scheduled for orthognathic surgery. The following conclusions were obtained. 1. The cause of malocclusion in skeletal class III patients were complex and interrelated ; backward upward rotation of the cranial base, forward inclination of the ramus, increase in the mandibular body length, and posteriorly located maxilla. 2. Seen on R2 (male-1.68mm, female-2.33mm), in skeletal class III, the maxilla is more posteriorly located than the normal group. 3. The cause of malocclusion in skeletal class III patients, consists of retrognathic maxilla(A1) male 22%, female 26%, prognathic mandible(B1) male 44%, female 34%, and combination of an retrognathic maxilla and prognathic mandible were male 28%, female 38%. 4. There was no significant difference in the anterior-posterior length of the maxilla(A4) between skeletal class III males with the normal group, while in the female subjects, the skeletal class III group showed a smaller maxilla(A4) compared to the normal group. 5. In skeletal class III patients the proganthic mandible was primarily caused by the inclination of the ramus(R3, R4) and mandibular body length(B4, B6) rather than ramus width(B3).

We investigated the influence of photon energy, couch and collimator angle differences between arcs on dose distribution of RapidArc treatment planning for prostate cancer. RapidArc plans were created for 6 MV and 10 MV photons using 2 arcs coplanar and noncoplanar fields. The collimator angle differences between two arcs were 0degrees, 15degrees, 30degrees, 45degrees, 60degrees, 75degrees and 90degrees. The plans were optimized using same dose constrains for target and OAR (organ at risk). To evaluate the dose distribution, plans were analyzed using CI (conformity index), HI (homogeneity index), QOC (quality of coverage), etc. Photon energy, couch and collimator angle differences between arcs had a little influence on the target and OAR. The difference of dosimetric indices was less than 3.6% in the target and OAR. However, there was significant increase in the region exposed to low dose. The increase of V15% in the femur was 6.4% (left) and 5.5% (right) for the 6 MV treatment plan and 23.4% (left), 24.1% (right) for the noncoplanar plan. The increase of V10% in the Far Region distant from target was 54.2 cc for the 6 MV photon energy, 343.4 cc for the noncoplanar and 457.8 cc for the no collimator rotation between arcs.

BACKGROUND: Patients who survive CPR are profoundly disabled and live with reduced quality of life. Therefore advanced directives are needed to ensure that life sustaining therapies are provided appropriately. This study compared the attitudes of elderly subjects toward advanced directives for CPR before and after receiving CPR education. METHODS: Between January and July 2007, 99 ambulatory persons aged older than 64 years were recruited from six community welfare facilities for the elderly. A questionnaire was distributed to obtain demographic data and their basic understanding and attitudes toward CPR. After providing information and showing a video clip on CPR, we compared whether having received this information influenced the thoughts of our subjects on CPR. RESULTS: None had had previous education on CPR, including prognostic information. Most overestimated the survival chance after CPR. Most wished to be resuscitated. After providing prognostic information on CPR and showing a short video clip, there was a change in their decision and the knowledge of CPR outcome seemed to influence their thoughts on CPR. In particular, the information on CPR prognosis greatly influenced their decision. CONCLUSION: Elderly people rarely have a chance to receive information regarding CPR. As a result, their decision to receive CPR may not accurately reflect the patient's wishes in emergency circumstances. It is important to pro- vide accurate prognostic information to help the elderly in their life-sustaining treatment decisions.

This study investigated the cultural characteristics of Shimizuomyces paradoxus in different nutritional and environmental conditions. The highest mycelial growth was observed in Schizophyllum (mushroom) genetics complete medium plus yeast extract agar medium, and the optimal temperature and pH were 25degrees C and pH 8.0, respectively. The optimal carbon and nitrogen sources were 1% dextrose and 1% peptone in agar. However, in liquid culture the highest dry mycelium weight was found for the potato dextrose agar and potato sucrose agar broths. The optimum inoculum size was five mycelial discs (5 mm) per 100 mL of broth, and the optimum liquid culture period was 25 days. This is the first ever report of S. paradoxus cultural characteristics.

Toxic megacolon is a devastating complication of colitis, which is commonly caused by inflammatory bowel disease. Frequently reported complications of toxic megacolon are bleeding, sepsis, colon perforation, and shock. Herein, we report a rare case of cardiac arrest that was likely caused by toxic megacolon in a 49-year-old male, who experienced 3 months of intermittent dyspnea and abdominal distension that abruptly worsened before presentation. Our case suggests that severe colon dilation complicated by toxic megacolon, especially accompanied by cardiopulmonary symptoms and signs, has the potential to progress to an abdominal compartment syndrome, which is a rare but life-threatening complication.
