1.A Case of Testicular Regression Syndrome.
Journal of Korean Society of Pediatric Endocrinology 2001;6(2):171-175
Testicular regression syndrome may be better known as vanishing testis syndrome to physicians. Such individuals are genetically male(46,XY), presenting with unilateral or bilateral absence of recognizable testis structures and absence of the Mullerian duct system. There is a wide spectrum of phenotypes depending on the stage of male embryogenesis at which testicular function ceased. We experienced a case of testicular regression syndrome presenting labial fusion at birth and report with the brief review of related literature.

This study was undertaken to elucidate any quantitative abnormalities of Tlymphocyte subsets (helper/inducer T cell; T cell and suppressor/cytotoxic T cell: T cell) and IgE levels in the peripheraI blood in atopic dermatitis patients by using monoclonal antibodies and enzyme immunoassay, respectively. In addition we have tried to ascertain whether there are any correlations betveen such immuiiologic abnormalities and the severity of the disease. The results showed that there were significant decrease in the mean percentage of T Cells and increase in the mean value of T/T cell ratios in patients with atopic dermatitis. These changes seem to relate to the severity of the disease when evaluated as groups. A significant increase in the mean value of serum IgE was found in atopic dermatitis patients and the change was related to the severity of the disease. But increase of serum IgE level did not correlated closely with the T cell abnormalities in each patients.

BACKGROUND: Doppler echocardiography is a non-invasive technique that has been used to evaluate LV diastolic dysfunction. Impaired left ventricular diastolic filling is known to occur in patients with coronary artery disease. Compared with those in normal subjects, Doppler-derived transmitral blood flow velocities have been reported to be reduced during early diastolic filling and to be compensatory elevated subsequent to atrial systole in patinets with coronary artery disease. But stiffness of myocardium normalize the E/A ratio, and normal E/A ratio may reveal increased ventricular filling pressure. We tried to investigate left ventricular filling parameters by Doppler echocardiography in patients with early myocardial infarction, and to compare left ventricular diastolic function regarding infarct location on EKG, one or multivessel disease on coronary angiography, and treatment modality. METHODS: From September 1993 to August 1995, Pulsed wave Doppler echocardiography was performed in patients with early acute myocardial infarction(N=95) and control group(N=20) within 5 days after admission, and parameters of diastolic function was evaluated. RESULTS: Echocardiographic data showed significant differences in mean ejection fraction, mean left ventricular mass, and mean left ventricular mass index between two groups. There was no significant difference in E/A ratio, deceleration time, and isovolumetric relaxation time between two groups. Neither, there was significant difference in each diastolic parameter for infarct related wall on EKG. And there was no significant difference in deceleration time for one or multi vessel disease on coronary angiography, treatment modality(conservative treatment, thrombolytic therapy, or primary PTCA). CONCLUSION: In patients with early acute myocardial infarction, left ventricular diastolic dysfunction was absent. And there was no significant correlation between the presence of diastolic dysfunction and the location of infarct related wall on EKG, or one or multi vessel disease, or treatment modality.

6.Arteriovenous Crossing Patterns in the Normal Retina.

The retinal blood bessels exit the optic disc and branch in a complex pattern to serve the metabolic need of the inner retina. As the vessels traverse the retina, the arteries and veins frequently cross one another. Recently, there has been renewed iterest in the orientation of the crossing retinal vessels at arteriovenous intersections, particularly as it relates to the risk of branch retinal vein occlusion. The authors studied standard fundus photographs of 30 subjects(60 eyes) who don't habve any retinal and systemic disorders. Arteriovenous crossings were analized for fundus location and relative orientation of the crossing vessels(vein-posterior or vein-anterior). In the superotemporal quadrant, A-V crossings were a greater number, distributed closer to the optic disc than the inferotemporal quadrant. Also a greater proportion of crossings was vein-posterior than the inferotemporal quadrant. These findings may explain the predilection for branch retinal vein occlusions to occur frequency in the superotemporal quadrant.

A rare case of giant invasive intraosseous schwannoma in lumbar vertebra with no neurologic deficit is reported. This tumor had vertebral body, left paravertebral tissue and lamina invasion and thus classified as type V giant invasive schwannoma according to Sridhar's classification of benign nerve sheath tumor. Because intraosseous portion was significantly larger than extraosseous portion, this tumor was mentioned as intraosseous schwannoma. Tumor was successfully resected using corpectomy, mesh cage insertion and posterior fixation. Pathological diagnosis was benign schwannoma.

Pityriasis rotunda is an uncommon dermatosis chacracterized by multiple, widely distributed, strikingly circular hypopigmented or hyperpigmented patches that are slightly scaly. Pityriasis rotunda has been associated with certain infective or malignant systemic diseases. No specific and effective treatment is available. A 27-year-old woman afflicted with multiple lesions of pityriasis rotunda on her back, buttock, abdomen and thighs without any local symptoms was treated with topical 20% urea and 0.025% tretinoin twice a day for 1 month. Complete remission with exellent cosmetic result was observed 30 days after this treatment. No recurrence was observed after 2 months later following commencement of treatment. Topical urea and tretinoin can thus be recommended as a practicable approach to the treatment of pityriasis rotunda.

We experienced one case of severe pituitary dwarfism in a 10 years old female girl. Magnetic resonance image (MRI) revealed transection of the pituitary stalk stalk with the formation of high intensity ectopic posterior lobe located at the median eminence and agenesis of an anterior lobe of pituitary gland. The serum growth Hormone (GH) response to clonidine and L-dopa revealed severe GH deficiency. The patient had responses to TRH, normal TSH and partial prolactin response, respectively. There was not response LH and FSH to GnRH. The morning cortisol concentration and serum T4 concentration were decreased below the normal range. These findings and no hyperprolactinemia suggested the presence of a vascular connection between the pituitary gland and hypothalamus, which is not visible on MRI. Sofar, the primary cause of idiopathic pituitary dwarfism in many patients is injury to hypothalamus by perinatal insults. In this patient, there was no history of perinatal insults and postnatal head trauma but transection of the pituitary stalk. We report a case of severe pituitary dwarfism due to agenesis with brief review of related litereature.
