A2 D time, a time interval from aortic second heart sound to the D point of mitral valve echogram, was reported as a valuable index of the left ventricular relaxation in its early diastole. It was suggested, however, that A2D time is influenced by variable factors rather than single factor. This study was performed to evaluate the influences of several on the A2D time and to extend our understandings in A2D time. For this purpose, A2D time was measured in 4 groups whose hemodynamic states were different, i.e.31 normal subjects (group A), 32 patients with essential hypertension without decompensation (group B), 10 normotensive patients with clinically full blown congestive heart failure (group C), and 11 patients with hypertensive heart failure (group D), and the mean values of each group were compared between the groups. Concordantly systolic hemodynamic parameters were observed and the relationship of A2D time and each of these parameters were observed. A2D time was consistently influenced by the level of left ventricle impedance and it is well correlated with parameters representing left ventricular systolic performances. In hypertensive subiects, A2D time was increased before the deterioration of the left ventricular systolic function but shortened after clinical heart failure. These findings suggest that A2D time may be of value in longitudinal follow-up of the left ventricular function in the hypertensive patients even before the development of clinical heart failure.

Hypertensive encephalopathy is characterized by an acute, severe rise in blood pressure associated with headache, nausea, vomiting, altered mental status, and focal neurologic deficits, and rapid improvement after control of blood pressure. An eight-year old boy had been admitted with symptoms of red urine, fever, headache, convulsion, and visual blurring of vision. Blood pressure was 140/90mmHg, and CSF exam revealed WBC 8/mm3, glucose 83mg/dL, protein 106mg/dL. Serum C3 was 8mg/dL, C4 17mg/dL, ASO 1,024 Todd units. Brain CT showed non specific findings, however, MRI revealed symmetric high signal intensity lesions on T2WI over the parieto-occipital areas bilaterally. These lesions had been completely resolved on the following MRI 4 weeks later.

To analyze the improvement of shouder function after arthroscpic subacrominal decompression and open repair for complete rotator cuff tear, we performed a prospective study in 14 patients using self evaluation form from the American Shouder and Elbow Society(ASES). All patients were treated with arthrscopic biplanar subacromial decompression and open repair by use of bony trough and followed for more than 1 year from November 1994 to June 1996 in Dankook university hospital. All patients were assessed preoperatively and at final follow-up using the standardised method of research committee of American shoulder & elbow surgeons. Tears of the rotator cuff were divided into medium(8 shoulders), large(3 shoulders) and massive(3 shoulders). Most of the patients were heavy laborers. Average age was 56.2 years (51-73 years). There were 9 male and 5 female patients. The dominant arm was affected in 8 shoulders. Postoperative abduction brace was used in all cases and passive range of mortion exercise was started from postoperative third day. At average follow-up of 17 months, average pain scores decreased to 0.8+/-1.1 from 6.9+/-2.3. Scores of ASES evaluation form increased to 87.3+/-12.2 from 35.8+/-16.3(p<0.05). As to the range of mortion, only internal rotation improved from T12 to T8(p<0.05). Thirteen patients achieved excellent or good result. Twelve patients returned to initial occupations. Arthroscopy is helpful to define the tear size which may affect the surgical approach and open repair by use of bony trough and tunnel is useful to recovery of shoulder function.

Dermatomyositis is a severe, idiopathic systemic disorder with predominant involvement of skin and skeletal muscle. The association of adult dermatomyositis and malignancy in particular has generated much attention. The reported prevalence of cancers in this disease varies from 6.7% to 52.2%. We experienced a concurrent case of transverse colon cancer and dermatomyositis on 67 year old female patient and report with review of literatures.

Castleman's disease, or giant Iymph node hyperplasia, is a Iymphoproliferative disorder which is characterized by Iymphoid hyperplasia with capillary proliferation, and divide histologically into two 0varieties, hyaline vascular and plasmal cell form. Some system manifestations are occasionally accompanied with the diseases, but peripheral neuropathy is a rarely reported manifestatlon of them and not in Korea. The present report describes a 40 year old female patient who had been admitted to Yonsei university medicai center because of progressive quadriparesis. On examination, she revealed various other manifestations such as hyperpigmentation, Iymphadenopathy, pitting edema, and bilateral papilledema. The electrophysiologic studies and sural nerve biopsy showed severe sensori-motor peripheral neuropathy showing features of mixed demyelinatlon and axonal degeneration. The Iymph node biopsy showed features compatible with Castleman's disease of hyaline vascular type. The recovery was poor over four month period despite of treatment with corticosterold.

BACKGROUND: Scapular notching can happen at diverse location depending on implant design or operative technique, therefore, it is easily misdiagnosed. Thus, this study purposed to suggest a method helpful to assess scapular notching. METHODS: The subjects were 73 cases of reverse shoulder arthroplasty (RSA) for cuff tear arthropathy during the period from May 2009 to April 2014 and followed-up for over a year. There was medialized RSA in 22 cases, bone increased offset RSA (BIO-RSA) in 36 cases, and metal increased offset RSA (metal-RSA) in 15 cases. Scapular notching was not determined by bone defect at the inferior of glenosphere as Sirveaux's classification, but scapular notching at the site where the rotational route of the polyethylene of humeral implant met the scapular neck were examined. The results were compared with conventional method. RESULTS: By conventional method, scapular notching was observed in 10 cases (45.5%) in medialized RSA, 12 cases (33.3%) in BIO-RSA, and none in metal-RSA. By new method, it was observed in 9 cases (40.9%) in medialized RSA, 10 cases (27.8%) in BIO-RSA, and none of metal-RSA. The site of scapular notching was apart from glenoshpere in 18 cases, and at inferior of glenosphere in 1 case. Absorption of bone graft was observed in 4 (11.1%) out of 36 cases of BIO-RSA. CONCLUSIONS: It is hard to distinguish scapular notching from absorption of bone graft in BIO-RSA, and bone absorption at the lateral lower end of glenoid in medialized RSA. Thus, it is considered useful to assess scapular notching at the site where the rotational route of the polyethylene insert meets scapular neck.

Thanatophoric dysplasia is the most common lethal congenital chondrodysplasia with characteristic features of narrow thorax, short rib, severe platyspondyly, short bowed limbs and skull deformity, etc. It is not a hereditary disorder and there is usually no family history of dysplasia. We experienced a case of thanatophoric dysplasia at 38 weeks of gestation with antenatal sonographic and abdominal radiographic findings of small thorax, short bowed extremities with surrounding thickened soft tissues and marked platyspondyly. Soon atter delivery, the baby died and post-mortem radiographs showed the characteristic findings of thanatophoric dysplasia.
