It is known that if the detrusor integrity is maintained, a single coordinated sustained contractile relaxation curve can be observed on rapid injection cystometry in the paralytic period after overdistention, but there is no study on its clinical significance. This study is to know the diagnostic usefulness of such relaxation curve in assessing the possibility of the voiding function recovery in the paralytic period after overdistention. We performed rapid injection cystometrys in 12 patients who had no contraction and sense on medium injection cystometry until 450ml infusion after non-neurogenic acute urinary retention by various causes, and compared the duration for recovery and the presence or absence of a single coordinated sustained contractile relaxation curve, the bladder volume at the first time of such a relaxation curve and the maximum pressure of contraction curve. The results were as follows; 1. All of 3 patients without a single coordinated sustained contractile relaxation curve did not recover their voiding function until three months after overdistention. 2. All of 9 patients with single coordinated sustained contractile relaxation curve recovered their voiding function within four weeks. 3. In 9 patients who recovered their voiding function, the smaller the bladder volume at the first such relaxation curve, the shorter the duration for recovery(r=0.69767. p=0.036), but there is no relationship between the maximum pressure of contraction curve and the duration for recovery(r=-0.10192, p=0.794). In conclusion, rapid injection cystometry is a useful clinical test to check the possibility of voidingfunction recovery within a few weeks in the paralytic period after acute overdistention.

Nonneurogenic neurogenic bladder is a condition in which the patient is with day and night wetting, infected urine, residual urine, reflux and upper tract damage without neurologic lesion or anatomical obstruction. Recently it is known that some patients with pediatric unstable bladder may contract their external sphincter to inhibit the detrusor contraction and pathological persistence of this "hold on" habit after they master a normal mature pattern of cortical control over the detrusor may result in nonneurogenic neurogenic bladder. The condition is reversible by bladder training with various methods. We report a case of nonneurogenic neurogenic bladder who is treated by self CIC after ileocecocystoplasty because bladder retraining has been failed due to high fever and severe frequency.

PURPOSE: evaluate the radiologic and clinical results of modified step-cut osteotomy for correction of cubitus varus deformity in children. MATERIALS AND METHODS: We analysed 16 children who had varus deformity preoperatively and received modified step-cut osteotomy. The results were evaluated by final follow-up radiographs and clinical results, which were humeral-elbow-wrist angle, lateral prominence, range of motion and complications. RESULTS: The average preoperative humeral-elbow-wrist (HEW) angle was -15.8degrees and average last follow-up HEW angle was +6.7degrees Lateral prominence under 5 mm occurred in 3 cases and one children showed limited motion and transient ulna neuropathy. CONCLUSION: The results demonstrate that modified step-cut osteotomy achieve good correction of cubitus varus without lateral bony prominence or complications.

Fibrodysplasia ossificans progressive (FOP) is an extremely rare disabling disorder characterized by progressive heterotopic ossification associated with congenital digital malformations. The purpose of this study is to delineate the problems in diagnosis and treatment of this rare disease, and to present their solutions. Nine Korean FOP patients have been followed up for average 7.2 years. Their medical records and radiographs were reviewed, and they were reexamined directly or interviewed by telephone. There were 6 female and 3 male patients. The age at the time of this study averaged 13.3 years (range, 4 to 23). In 5 cases, the first clinical manifestation was migrating scalp and neck mass at the age of 1-2 years. The diagnosis was delayed for 3 year and 5 months at average although all the patients had pathognomonic big toe anomaly. Surgical excision of heterotopic ossification in an attempt to increase the joint motion was performed in 4 cases but in vain. Posterior spinal fusion in 1 case failed to prevent progression of scoliosis and trunk decompensation. Disodium etidronate, tried in 3 patients, brought no effective symptom relief. All the patients in their 20's were household ambulators. Understanding the clinical manifestation of this disease enables early diagnosis, by which unnecessary and harmful procedures such as surgical biopsy or excision can be avoided, although no effective treatment has been developed.

PURPOSE: The purpose of this study is to investigate the learning styles of students at Kyungpook National University(KNU) School of Medicine and to assess its implications on teaching-learning methods in medical school. METHODS: 571 students in all years of medical school were invited to complete a questionnaire via online. For this study, Felder's Index of Learning Styles(ILS) was used, which included 49 items. Felder's ILS measures the learner's relative preference for each of the five dichotomous learning style dimensions. RESULTS: 242(42.3%) students completed the questionnaire. More than 80% preferred sensitive information and more than 60% preferentially took in visual information. Both males and females preferred sensing and visual learning materials. On average, The students at KNU school of Medicine were reflective, sensing, visual, global and inductive. CONCLUSION: From these results, we suggested some effective methods of teaching-learning based on the students' preferences and some perspectives for future works.

PURPOSE: Kyungpook National University School of Medicine initiated a pilot project to admit small number of qualified students who received BS degree or above in the field of sciences in 1996. This study was conducted to evaluate effectiveness of the pilot project. METHODS: Students' academic grades, outcome of their opinion surveys on adaptability to the school life, difficulties and problems from the classes of 1996 to 2001 were analyzed. RESULTS: A total of 57 students were admitted to this program over the past 7-year period, 54.8% of them from natural science major and 36.8% from engineering. Students admitted with BS degree were performing above average in the class by % rank. There was no significant difference in academic performance between the natural science and the engineering major. Of 20 graduated, only one took career in basic medical science (physiology). The students thought undergraduate education was helpful in maturing personal characters than in knowledge or skill attainment. CONCLUSION: The achievement of medical students admitted after baccalaureate level was comparable to that of students with two years of premedical education.

BACKGROUND AND PURPOSE: Only a few studies have investigated the relationship between different subtypes and disease progression or prognosis in patients with behavioral variant frontotemporal dementia (bvFTD). Since a localized injury often produces more focal signs than a diffuse injury, we hypothesized that the clinical characteristics differ between patients with bvFTD who show diffuse frontal lobe atrophy (D-type) on axial magnetic resonance imaging (MRI) scans versus those with focal or circumscribed frontal lobe atrophy (F-type). METHODS: In total, 94 MRI scans (74 scans from bvFTD and 20 scans from age-matched normal controls) were classified into 35 D- and 39 F-type bvFTD cases based on an axial MRI visual rating scale. We compared baseline clinical characteristics, progression in motor and cognitive symptoms, and survival times between D- and F-types. Survival analyses were performed for 62 of the 74 patients. RESULTS: While D-type performed better on neuropsychological tests than F-type at baseline, D-type had higher baseline scores on the Unified Parkinson's Disease Rating Scale (UPDRS) Part III. Evaluations of motor progression showed that the disease duration with motor symptoms was shorter in D-type than F-type. Moreover, the survival time was shorter in D-type (6.9 years) than F-type (9.4 years). Cox regression analyses revealed that a high UPDRS Part III score at baseline contributed to an increased risk of mortality, regardless of the pattern of atrophy. CONCLUSIONS: The prognosis is worse for D-type than for those with F-type. Shorter survival in D-type may be associated with the earlier appearance of motor symptoms.
