We performed original and modified technique of Mays' glanuloplasty in 6 and 12 cases respectively. The results were as follows: 1. 6 cases of mild from of hypospadias (2 cases of coronal, 4 cases of dist. penile) and 12 cases of severe form of hypospadias (5 cases of prox. penile, 6 cases of penoscrotal, 1 case of perineal) on pre-chordectomy but all cases became severe from of hypospadias (2 cases of prox. penile, 15 cases of penoscrotal, 1 case of perineal) on post-chordectomy. 2. The postoperative complications were 3 cases (50.0%) (1 case of meatal stenosis, 2 cases of meatal necrosis) in original technique of Mays' glanuloplasty and 2 cases of meatal stenosis (16.7%) in modified technique of Mays' glanuloplasty.

Duret hemorrhage is characterized by an upper brainstem hemorrhage due to increased intracranial pressure by mass effect such as subdural hematoma or a brain tumor. The anteroposterior elongation and downward displacement of the upper brainstem by transtentorial herniation results in the compression and tearing of the paramedian perforating vessels that feed the upper brainstem tegmentum. The consequent hemorrhage that involves the upper brainstem renders recovery to be almost impossible. Following a tricuspid valve replacement surgery, a 56-year-old woman developed a left fronto-temporo-parietal nontraumatic subdural hematoma resulting in transtentorial herniation of the left mesial temporal lobe. A successful surgical evacuation of the hematoma was done with clinical improvement. Two days later, she was referred to neurology with an aggravated right side weakness, dysarthria, and a newly developed extraocular movement disturbance. A brain CT and MRI showed a pontine hemorrhage. We report a case of pontine hemorrhage, a Duret hemorrhage, after the surgical evacuation of nontraumatic subdural hematoma.

BACKGROUND: Cardiogenic embolic infarction is the most preventable type of ischemic stroke. This study was under-taken to compare the infarct size, prognosis, and risk factors between cardiogenic embolic infarction (CE) and large artery atherosclerotic infarction (LAA). METHODS:We reviewed the medical records and brain computed tomography/magnetic resonance image (CT/MRI) scans of patients with CE or LAA during the period between January 1996 and May 1998. Patients with lacunar and posterior circulation infarctions were excluded. A slice of brain CT/MRI scan showing the largest lesion was selected in each patient and the area of infarction was then measured. Prognosis was determined by the Modified Rankin Disability Scale (MRDS) and was grouped as either good (MDRS 0, 1, 2) or poor (MDRS 3, 4, 5). RESULTS: The study included 103 patients : 50 with CE (NVAF in 23, VHD with or without AF in 13, prosthetic valve in 6, and others in 8) and 53 with LAA (large artery thrombosis in 29, and artery to artery embolism in 24). The infarct size of CE (23.2+/-14.7 cm2) was significantly larger than that of LAA (11.4+/-10.5 cm2) (p<0.001). The infarct size of NVAF (29.0+/-19.1 cm2) was significantly larger than that of VHD with or without AF (19.2+/-11.5 cm2) (p<0.05). Patients with CE had a worse prognosis (poor in 46%) than those with LAA (poor in 23%) (p<0.05). CONCLUSIONS Our results showed that CE led to larger lesions and worse outcomes. Therefore, we emphasize the importance of primary and secondary preventions of stroke in patients with cardiogenic embolic sources.

The management of LcP disease is dependent on the prognosis yet. This may be difficult to predict for the individual child, particularly at the onset of the disease when radiological sign may be minimal. But some form of conservative treatment is generally commenced before the prognosis become apparent. The purpose of this study was to determine the validity of Catterall's grouping and value of other radiological and clinical factors in predictiong prognisis and also the correlation between the clinical and radiological results at the conclusion of the pathological precess in LCP disease. Between the clinical and radiological results at the conclusion of the pathological process in LCP disease. Between June 1986 and July 1995, 64 childrens with LCP disease were tearted in Kyungpook University Hospital, 44 hips of 40 childrens who had adequate clinical and radiological data were reviewed. The average follow-up period was 5.4 years. The results obtained were followings: 1.The mean age at first visit or diagnosis was 6.7 years. 2. Of 40 childrens, 4 childrens had bilateral involvement. Boys were more predominat. 3. The degree of uncovering of femoral head and medial joint space at the presentation seemed to be prognostic factor for the end results. 4. Catterall & lateral pillar classification seemed to be difficult at presentation of the disease but also an important guide to determine the prognosis.

BACKGROUND: Several abnormalities of the autonomic regulation of the heart have been noted after acute myocardial infarction(AMI). Measurement of heart rate(HR) variability has been reported to provide indirect, noninvasive estimate of the cardiac efferent parasympathetic activity. The purposes of this study were to get the information on heart rate variability after AMI and to determine its relation to clinical and hemodynamic data. METHODS: We measured HR variability in 28 patients(23 men and 5 women : mean age, 56.6+/-10.4 years) 3-15days after AMI, in 25 patients with unstable angina and in 21 normal subjects by using triangular interpolation of the frequency distribution histogram om normalto-normal RR intervals from Holter tapes. RESULTS: HR variability was lower in AMI than unstable angina patients(357.9+/-118.6 versus 426.1+/-122.5 msec : p<0.05) and normal subjects(525.1+/-137.4 msec : p<0.025). There was no difference for infarct site, thrombolytic therapy, presence of Q-wave. HR variability was significantly related to mean 24-hour HR, left ventricular ejection fraction(all p<0.0001), left ventricular end diastolic diameter(p<0.05). HR varability was lower in patients belonging to Killip class 2-4 and who reqired the use of diuretics or digitalis(all p<0.05). CONCLUSION: After AMI, HR variabillity was reduced and significantly related to clinical and hemodynamic indexes of severity. Measurement of HR variability early after AMI may offer important clinical information for the early high stratification of patients.
