Measurements of mitral flow velocity by pulsed Doppler echocardiography are very useful in evaluating left ventricular diastolic filling properties. In hypertensive patients, abnormalities of diastolic function may precede systolic abnormalities and may serve as a more sensitive marker of end organ damage. We estimated left ventricular nass by 2-D echo short axis area-length method and compared with peak mitral flow velocity in early diastole(PFVE)and during atrial systolic(PFVA). There was a significant increase of LV mass and LV mass indices in the hypertensive patients and PFVE/PFVA ratio was decreased in them. Aithough there was no relationship between blood pressure and PFVE/PFVA ratio, a significant relationship was demonstrated between LV mass index and PFVE/PFVA ratio in the hypertensive patients.

The spindle and epithelioid cell nevus, is known also as Spitz's nevus or benign juvenile melanoma. The histologic picture of the lesion often closely resembles that of a malignant melanoma, but spindle and epithelioid cell nevus hehaves benignly. Criteria for accurate histological diagnosis of this nevus now exist. However, a difficult lesion occasionally brings one to the worrisome situation even now. We experienced four cases (three children and one adult) of spindle and epithelioid cell neveus with nodular or macular skin lesions. In children (7/F, 9/F, 4/M), all of the lesion show a solitary pinkish red or light brown nodular firm masses, 0.7 cm to 1.0 cm in greatest dimension, which are located at the left posterior thigh, posterior neck and right anterior neck region, respectively. In adult (36/F), the lesion shows a light brown, erythematous macule, 0.8 cm in greatest diameter, in the skin of the back. Microscopically, both spindle and epithelioid cells are found in all the four cases, but epithelioid cells predominate in children and spindle cells predominate in adult.

BACKGROUND: The purpose of this study was to evaluate the postoperative magnetic resonance imaging (MRI) results of minimal-tying (one medial-row tie among 4 medial-row sutures) on the medial-row in double-row suture-bridge configuration (2x2 anchor with 4x4 suture stands). METHODS: From 2011 March to 2012 July, 79 patients underwent arthroscopic rotator cuff repair using 2x2 anchor double-row configuration. The mean age was 61.3 years (range, 31-81 years). Two double-loaded suture anchors were used for medial-row. Four medialrow stitches were made with only one medial-row knot-tying (the most anterior suture). Lateral-row was secured using the conventional suture-bridge anchor technique; all 4 strands were used for each anchor. Repair integrity was evaluated with MRI at mean 6.2 months postoperatively. Retear and the pattern of retear, change of fatty infiltration, and muscle atrophy of supraspinatus were evaluated using pre- and postoperative MRI. RESULTS: Repaired tendon integrity was 38 for type I, 30 for type II, 6 for type III, 4 for type IV, and 1 for type V, according to Sugaya classification. Considering type IV/V as retear, the rate was 6.3% (5 out of 79 patients). Medial cuff failure was observed in 4 patients. Fatty atrophy of supraspinatus was significantly improved postoperatively according to Goutallier grading (p=0.01). The level of muscle atrophy of supraspinatus was not changed significantly after surgery. CONCLUSIONS: Minimal tying technique with suture configuration of four-by-four strand double-row suture-bridge yielded a lower retear rate (6.3%) in medium to large rotator cuff tears.

We report a case of congenital vellus hamartoma, which consists of numerous matured vellus hair follicles and sebaceous glands. This patient is 4-month-old male with multiple, variable sized nodules on the right epicanthsl fold area since birth. Histopathologically, some of the infundibular portion of the vellus hair shows irregular and reticulated hyperplasia. There are numerous well-formed vellus hair follicles surrounded with thick fibrous sheath and some of them are associated with rudiment sebaceous glands.

With the increase of frequency and the recent development of surgical treatment in brachial plexus injury, the requirement for accurate assessment between supra and infraganglionic injury is increased. Cervical myelography has been the popular tool in evaluating the root lesion since the first introduction of Murphey et al. in 1947. However, the invasiveness of procedure has been the impediment to the common-use. But with the utilization of water-soluble contrast media, Metrizamide, such impediment can be alleviated. Author has performed myelography in 27 patients along with surgical exploration in 18 patients since 1984. And the results were as follows. 1. 85% of 27 patient revealed anomaly of root in myelography. 2. Traumatic menimgoceles were typical findings and most of them were located at C7 and C5. 3. Myelography reaveled 70%(28 root) of anomalies among 40 root lesions, confirmed by surgical explorations. 4. Myelography is considered to be very effective in evaluating supra and infraganglionic root lesions when its results is correlated with physical and other neurological examination.

Myocardial bridging is defined as a condition where a segment of a major epicardial coronary artery running intramurally through the myocardium. Although this abnormality is usually regarded as an incidental finding at angiography, it has been associated with myocardial ischemia, infarction, and sudden death. Standard treatment involves beta-adrenergic receptor blockers, surgery with dissection of the overlying muscle fibers, or coronary artery bypass grafting. A few cases of the intracoronary stent implantation have been reported as an alternative treatment in individual patients with myocardial bridging. We report a case of intracoronary stenting in a severe systolic narrowing at the middle segment of the left anterior descending artery in a patient complaining of recurrent chest pain despite medical treatment.

OBJECTIVE: From November 30, 2016, the Korean Government carried the revised Medical Dispute Mediation and Arbitration Act into effect. Mediation will start automatically without agreements of the defendant, when the outcome of the patient was death, coma more than a month or severe disability. Cerebral aneurysm has a definite risk of bad outcome, especially in the worst condition. Any surgical intervention to this lesion has its own high risk of complications. Recently, Seoul central district court decided 50% responsibility of the doctors who made a rupture of the aneurysm during coiling (2015Ga-Dan5243104). We reviewed judicial precedents related to cerebral aneurysms in lawsuit using a web search.METHODS: We searched judicial precedents at a web search of the Supreme Court, using the key words, "cerebral aneurysm".RESULTS: There were 15 precedents, six from the Supreme Court, seven from the High Court, and two from district courts. Seven precedents were related to the causation analysis, such as work-relationship. Five precedents were malpractice suits related bad results or complications. Remaining three precedents were related to the insurance payment. In five malpractice precedents, two precedents of the Supreme Court reversed former two precedents of the High Court.CONCLUSION: Judicial precedents on the cerebral aneurysm included not only malpractice suits, but also causation analysis or insurance payment. Attention to these subjects is needed. We also need education of the independent medical examination. To avoid medical disputes, shared decision making seems to be useful, especially in cases of high risk condition or procedures.

Pagonimus Westmani, occuring as an important human infestation of the lung, is widely distributed in the Far East ; Korea, Japan, China and the Philippines. Since Otani found the parasites for the first time in the human brain in 1887, it has been established that cerebral infestation occurs with the highest frequency among extrapulmonary involvement. In 0.8 to 25 percent of patients infested with the lung flukes cerebral paragonimiasis may be developed. The larvae may procedure arachnoiditis, abscess, fibrous cystic lesions and granulomas in the brain. Based on a review of the literatures and upon the 7 cases of cerebral paragonimiasis which have been observed by the authors at the National Medical Center, Seoul, Korea, the following points are stressed. 1) Males had a significantly higher prevalence than females. Cerebral paragonimiasis was most commonly found in young adults(16 to 25yrs). 2) Clinically the patients with cerebral involvement were characterized by Jacksonian type of epilepsy, headache and visual disturbance. Mental deterioration, hemiplegia, hemihypesthesia, homonymous hemianopsia and optic atrophy were the five major signs. 3) The patients having symptoms for less than 6 months developed mild leukocytosis in many cases. All the cases of cerebral paragonimiasis revealed positive reaction in the intradermal tests with purified antigens of P. Westermani. 4) On skull films multiple round or oval cystic calcification was diagnostic value for cerebral paragonimiasis. On angiogram vascular staining and abnormal vessels were not disclosed. On pneumoencephalogram subcortical atrophy or filling defect of the ventricle may be showed. 5) The predilection area of the granuloma and fibrous cystic mass were the occipital, posterior parietal and posterior temporal lobes. 6) The patients with chronic stabilized cerebral paragonimiasis. having intractable symptoms and signs, could not be improved with Bithionol treatment. But headache, vomiting, visual disturbance, facial weakness and especially intractable seizure were improved in our cases treated with surgical operation.

OBJECTIVE: Age is a strong predictor of mortality in traumatic brain injuries. A surgical decision making is difficult especially for the elderly patients with severe head injuries. We studied so-called 'withholding a life-saving surgery' over a two year period at a university hospital. METHODS: We collected data from 227 elderly patients. In 35 patients with Glasgow Coma Score 3-8, 28 patients had lesions that required operation. A life-saving surgery was withheld in 15 patients either by doctors and/or the families (Group A). Surgery was performed in 13 patients (Group B). We retrospectively examined the medical records and radiological findings of these 28 patients. We calculated the predicted probability of 6 month mortality (IPM) and 6 month unfavorable outcome (IPU) to compare the result of decision by the International Mission for Prognosis and Analysis of Clinical Trials in TBI (IMPACT) calculator. RESULTS: Types of the mass lesion did not affect on the surgical decision making. None of the motor score 1 underwent surgery, while all patients with reactive pupils underwent surgery. Causes of injury or episodes of hypoxia/hypotension might have affected on the decision making, however, their role was not distinct. All patients in the group A died. In the group B, the outcome was unfavorable in 11 of 13 patients. Patients with high IPM or IPU were more common in group A than group B. Wrong decisions brought futile cares. CONCLUSION: Ethical training and developing decision-making skills are necessary including shared decision making.
