1.The 'Overlooked' Cause of Vesicoureteral Reflux in Children - Urethral Abnormalities.
Korean Journal of Urology 2004;45(10):965-975
PURPOSE: To emphasize the significance of urethral abnormalities as the cause of vesicoureteral reflux in children. MATERIALS AND METHODS: Current literatures were evaluated and the data in my laboratories were added. RESULTS: Vesicoureteral reflux in boys which is more common in neonates and infants, has the tendency of quicker spontaneous resolution compared to girls in spite of its bilaterality and high grade. On the other hand, vesicoureteral reflux in girls, more commonly found after the first year of life, shows slower spontaneous resolution than boys although it shows lower grades when compared to boys. Such findings are attributed to sexual difference and the urethra is suspected to play an important role. The urethra influences the bladder function through sphincter to bladder reflex during the filling phase, and urethra to bladder reflex during the voiding phase. Cobb's collar which is an obstructive urethral lesion in males, is supposed to disappear after a short existence during fetal or neonatal period. However, if it causes severe obstruction or fails to disappear, it is suspected to result in the typical male type of vesicoureteral reflux caused by voiding dysfunction and increased intravesical pressure created by obstruction itself and urethral instability. Meanwhile, urethral abnormalities in girls such as mucosal web or female hypospadias causes vaginal voiding leading to dysfunctional voiding after toilet training and consequently results in vesicoureteral reflux through bladder instability, increased intravesical pressure and urinary tract infection as well as urethral instability. CONCLUSIONS: Since the meaning of surgery in vesicoureteral reflux, in view of kidney preservation, is becoming limited to the extent of recognizing the merit of surgical correction as merely discontinuing prophylactic antibiotics, studies of urethra in children with vesicoureteral reflux is another filed in (pediatric) urology which requires more active research and treatment.

2.The Incidence of Pityrosporum Orbiculare and Pityrosporum Ovale on Normal Skin.
Korean Journal of Dermatology 1982;20(5):631-639
In microscopical survey of clinically normal skin, P. orbiculare was found to be present on scalp, face, anterior chest, back, arm and leg in 68.2%, 68.3%, 90.2%, 86.4%, 28.6% and 16.7% respectively, and P. ovale was present in scalp, face, anterior chest, back, arm and leg in 84.1%, 56.1%, 51.2%, 38.6%, 19.0% and 7.1%. P. ovale was dominant species in scalp, on the other hand P.orbiculare was dominant species in anterior chest and back. The large number of spore of P. ovale was present on scalp, on which P. ovale was dominant species, and on anterior chest and back, the number of spore of P. orbiculare was more increased than the numbers of P. ovale. The hyphae, identical in size and shape with those of Malassezia furfur, were found on scalp in one subject. In cultural survey, the pcsitive culture rate in P. orbiculare was showed in over all from 87.5% to 80.8% and in P. ovale from 33.3% to 88.2%. Germ tube formation on culture was found in 3 subjects on anterior chest and in one subject on back.

The authors reviewed both the clinical and radiographic results of 36 bipolar hemiarthroplasty using the porous-coated Harris-Galante uncemented femoral stem performed for avascular necrosis in 30 patients from January 1985 to June 1992. The average age was about 45.6 years and the average follow-up was fifty-four months. Clinical results by the Harris evaluation method were excellent in 33 cases, good in 2 cases, and fair in 1 case. The radiographic fixation of the femoral stem at final follow-up was bony ingrowth fixation in 31 cases, fibrous ingrowth fixation in 4 cases, and unstable fixation in 1 case. There was neither medial nor superior migration of the bipolar cup of more than two millimeters.

Thirteen guinea pigs and 23 rabbits were challenged with 300 metacercariae of Clonorchis sinensis each and the recovery of adult worms and egg counts in feces were compared at 11-13 weeks post-infection in guinea pigs and at 7-9 weeks post-infection in rabbits. The recovery rate of adult worm was 23.5 percent in guinea pigs and 20.l-30.5 percent in rabbits. The mean E.P.G. of these animals in above period of infection was 106 in guinea pigs and 121 in rabbits. When one hundredth of E.P.G. was expressed as X and the number of adult worms as Y, the relationships between X and Y were as follows; Y=0.8X+10.8 in guinea pigs and Y=0.7X+6 in rabbits.

A case of multiple myeloma associated with adenocarcinoma of the stomach was review. A 59-year, old Korean man had been abmitted to St. Mary's Hospital in January 1984, with chief complaint of posterior neck pain, and intermittent headache for one year prior to amission. Osteo lytic punched-out lesions were noted on skull and other skeletal x-ray films. Bone marrow aspirates revealed diffuse infiltration of mature and immature plasma cells. Laboratory findings revealed anemia and Bence-Jones proteinuria. Immunoelectrophoresis revealed findings consistent with IgA-lamda type multiple myloma. Alkylating agents and steroids were tried with some clinical improvements. In August 1985, the patient revisited outpatient clinic with chief complaints of epigastric pain and neck mass. Endoscopic biopsy and excision biopsy of the cervical lymph node were performed. By microscopic examination, adenocarcinoma of the stomach and metastasis of multiple myeoma to the supraclavicular lymph nodes were confirmed. Subtotal gastrectomy was performed. By gross and microscopic revealed metastasis to the regional lymph nodes.

We have experienced a case of plexiform neurofibrorna of the right upper eyelid and orbit in a 12-year-old girl who had typical skin features of neurofibromatosis and no family history. The non-pulsating proptosis of the right eye and diffuse thickening with hypertrophy of the upper lid, had increased insiduciusly since the birth on. Biopsy taken from eyelirl lesion showed the features of plexiform neurofibroma. Skull X-ray and brain computerized tomogram showed that the right orbit was wider, with the enlarged mass and defects in orbital roof and lesser and greater wings of the sphenoid bone. The surgical excision of the right eyelid lesion was performed.

Transmitral left ventricular diastolic inflow velocities determined by pulsed Doppler in 47 normotensives, 80 hypertensives and 44 age-matched hypertensives were measured to evaluate the effects of age and left ventricular hypertrophy on left ventricular diastolic fuction in normotensives and hypertensives. The results were as follows: 1) The peak E velocity in normotensives(77.82+/-13.53cm/sec) was significantly different from those of hyeprtensives(58.13+/-11.80cm, p<0.01) and age-matched hypertensives(59.31+/-10.94cm/sec, p<0.01). The peak E/A in normotensives(1.31+/-0.45) was significantly different from those of hypertensives(0.83+/-0.21,p<0.01) and age-matched hypertensives(0.83+/-0.20, p<0.01). 2)In normotensives, simple linear regression analysis revealed strong inverse correlations of peak E with age(r=-0.758, p<0.01), peak E/A with age(r=-0.748, p<0.01), but no significant correlation of peak E and peak E/A with LVMI(p>0.05). Stepwise regression analysis revealed that age was the most important correlate of peak E and peak E/A in normotensives(peak E: R
