Basaloid follicular hamartoma(BFH) is a rare, benign adnexal tumor with a wide clinical appearance spectrum. A characteristic finding is multifocal islands in the papillary dermis and branching cords of basaloid epithelial cells in continuity at various sites with the basal layer of the epidermis and the hair follicles. We present a case of basaloid follicular hamartoma combined with basal cell epithelioma that developed on the tip of the nose in a 75-year-old man. To our knowledge, this is the first case report of basaloid follicular hamartoma combined with basal cell epithelioma in the Korean literature.

PURPOSE: We report a case of a scleral perforation during inferior rectus recession in congenital fibrosis of extraocular muscles and the management of this perforation with a scleral patch graft. CASE SUMMARY: A 20-month-old female with bilateral ptosis, absence of elevation and a chin-up position was diagnosed with congenital fibrosis of extraocular muscles. Because severe esotropia in the downward gaze was observed, we first performed esotropia surgery. After 1 year, she underwent a bilateral ptosis correction. We decided to perform bilateral inferior rectus recession due to an abnormal head posture and the absence of elevation. Because the inferior rectus muscles were extremely tight and adhered to the sclera, hooking and isolating these muscles during surgery was difficult. After muscle suture placement, a portion of the sclera that contacted the left inferior rectus was chipped off as this muscle was disinserted with blunt Westcott scissors. A scleral perforation was observed, thus, we placed a scleral patch graft using the donor sclera and finished the bilateral inferior rectus recession. No abnormal findings for the vitreous or retina were detected. At 8 months after surgery, the patient exhibited exotropia of 12 prism diopters in her primary gaze. Her abnormal head posture nearly disappeared. CONCLUSIONS: Careful isolation and disinsertion of the muscle from the globe is necessary in the treatment of patients who are expected to exhibit severe adhesions between the muscle and sclera, such as patients with congenital fibrosis of extraocular muscles.

We identified the early and late prognostic factors of acute myocardial infarction, and evaluated the clinical differences and the prognosis between Q-wave myocardial infarction and non-Q wave myocardial infarction. Total 146 patients who were managed from Jan 1987 to Aug. 1989 at hallym University hospital were evaluated. According to the presence or absence of Q wave on electrocardiogram, the patients were divided into two groups : a Q wave myocardial infarction group(QMI) and a non-Q wave myocardial infarction group (NQMI). Among 146 patients 109 patients(74.7%) had QMI and 37 patients(25.3%) had NQNI. The mean age, male to female ratio and serum cholesterol level were similar in both groups. But peak level of CPK was significantly higher in the QMI group than that in the NQMI group(P<0.01). Left ventricular end-systolic dimension and ratio of left ventricular dimension to wall thickness in the QMI group were significantly higher than that in the NQMI group(P<0.01). There were no significant differences between two groups in the incidences of mortality, postinfarction angina and re-infarction. During the in-hospital period female gender, old age(more than 60 years), Killip class at admission, early reinfarction and a history of hypertension were significant prognostic factors. main causes of death during the in-hospital period were ventricular tachyarrthymia, heart failure and cardiogenic shock. The incidences of mortality, heart failure and post-infarction angina during a mean follow-up period of 14 months (6~30months) were same in the two groups. The late prognostic factors were old age(more than 60 years), Killip class at admission, heart failure occured during follow-up period(P<0.001) and a history of diabetes mellitus(P<0.05). The patients with late postinfarction angina had more dilated left ventricular end-systolic demension(P<0.05) and lower fractional shortening(P<0.01) than those of patients without late postinfraction angina. There were no significant difference in long term survival rate between QMI group and NQMI group. Further prospective study should be performed to clarify the short and long term prognosis in patients with acute myocardial infarction treated by reperfusion.

Treatment of rotator cuff tears by open subacromial decompression has known successful in decreasing pain and restoring function in patients who have failed nonoperative treatment. But, open rotator cuff repair may result in significant deficits in strength and active motion by deltoid separation from the acromion. Deltoid detachment may be avoided by repair using mini-open technique. Arthroscopic subacromial decompression and the rotator cuff repair revel satisfactory results. Subacromial decompression involves decompression of the coracoacromial arch including routine release or resection of the coracoacromial ligament. Recent ligament-cutting studies have confirmed the role of the coracoacromial ligament as a static restraint to superior humeral head displacement. Complete resection of the coracoacromial ligament may be avoided through minimized arthroscopic acromioplasty. We evaluated all 11 patients with rotator cuff tears who underwent arthroscopic minimized subacromial decompression and rotator cuff repairs using mini-open technique. Their average age was 53 years (26 to 64 years); and the average follow-up was 13 months. Preoperatively, all patients complained pain and weakness. Follow-up using modified Hospital for Special Surgery shoulder score showed good to excellent results in 10 cases and poor results in 1 case an average 13 months postoperatively. We found that arthroscopic minimized subacromial decompression and repair using mini-open technique are safe, effective procedure for addressing cuff tears of a wide range of sizes.

Purpose: Total hip arthroplasty (THA) using dual mobility components (DMC) is a reasonable surgical option for displaced femoral neck fractures in elderly patients, resulting in lower dislocation rates and improved stability. The purpose of this study was to investigate the clinical outcomes and risk factors responsible for mortality in elderly patients who were diagnosed with a displaced femoral neck fracture and had undergone DMC-THA. Materials and Methods: Out of 147 cases of THA from December 2018 to June 2020, a total of 79 cases were enrolled in this study, with the following characteristics: (1) Garden stage III or IV, (2) over 75 years of age, and (3) over 1 year of follow-up. All the patients received DMC-THA surgery using the anterolateral approach. Results: The mean follow-up period was 15.0±8.43 months and a total of one dislocation case was observed. The mortality rate was 17.7% (14/79), and it was especially higher in patients with a past medical history of malignancy (odds ratio [OR]=7.18, p=0.03) or a cognitive disorder such as dementia (OR=5.48, p=0.03). Preoperative low initial hemoglobin levels (OR=0.65, p=0.04) and low UCLA (Uni-versity of California at Los Angeles) score (OR=0.47, p=0.02) were also associated with mortality. Conclusion When considering THA as a treatment approach in elderly patients with a displaced femoral neck fracture, a high mortality rate is expected in patients with low preoperative hemoglobin levels or a history of malignancy or cognitive disorders. Hence, thorough monitoring and management should be undertaken before and after surgery.

Bisphosphonate is used widely for osteoporosis management. On the other hand, some studies have reported that prolonged use of bisphosphonate without a proper resting period can cause insufficiency fracture and, in rare cases, fractures on the femur neck. This paper reports a case of an elderly patient who suffered bilateral femur neck insufficiency fractures induced by non-stopped long-term bisphosphonate therapy. The patient complained of pain in her buttocks at the first visit. During the admission period, inguinal area pain newly developed. Both a femur neck insufficiency fracture was observed on the hip radiographic image. Hip pinning and postoperative parathyroid hormone treatment were performed. The patient was discharged without specific complications and reported improvement in symptoms on the last follow-up. Several authors have reported one-sided femoral neck insufficiency fractures due to bisphosphonate use, but the present case is uncommon in that it occurred simultaneously in both femur necks. In addition, in the case of bilateral femur fractures, the walking ability after surgery is lower than that of one-sided fracture cases, so active rehabilitation is necessary.

The bladder is involved in 1% to 3% of all hernia cases. We report a case of a large paraperitoneal bladder hernia (BH) in a 59-year-old man who had a palpable scrotal mass. Several techniques and approaches have been described for managing BHs. We performed a laparoscopic partial cystectomy and herniorrhaphy. This is the first case report on the repair of a large BH by use of a laparoscopic technique in Korea.

To evaluate effect of coronary collateral circulation on left ventricular function in patients with acute myocardial infarction, global ejection fraction(EF), left ventricular end distolic pressure(LVEDP), peak creatine kinase(CK) level and regional wall motion were analysed and compared in 30 patients with acute myocardial infarction according to grade of coronary collateral circulation. Patients with total or near total(above 95% of diameter) occlsion of left anterior descending coronary artery without significant lesion in right coronary artery or left circumflex artery were selected and divided into 3 groups according to the degree of collateral circulation on coronary angiography, to be compared by the index of ejection fraction, peak creatine kinase level, left ventricular and diastolic pressure and regional wall motion. The result are as following : 1) There were no statistically significant differences in ejection fraction, peak creatine kinase level, left ventricualr and diastolic pressure among the groups. 2) Regional wall motion of infarct related area of G2+3 group(adequate collateral) were better than that of G0(no collateral) group(p<0.05). Therefore, adequate coronary collateral circulation in acute myocardial infarction is thought to have beneficial effect on left ventricular function especially in regional wall motion of infarct related area.

BACKGROUND: Reperfusion of ischemic myocardium is clinically encountered during thrombolytic therapy of acute myocardial infarction, percutaneous transluminal coronary angioplasty(PTCA), and coronary artery bypass graft(CABG). Reperfusion results in endothelial dysfunction characterized by a reduced release of endothelium-derived relaxing factor(EDRF) in animal studies. Studies with experimental animals have emphasized the role of oxygen free radicals and lipid peroxidation in pathophysiology of reperfusion injury and myocardial stunning. The object of this study is to determine whether endothelial dysfunction was developed after open heart surgery and to evaluated the role of oxygen free radical and lipid peroxidation in reperfusion injury. METHODS: The study group was comprised 13 patients who underwent open heart surgery(male/female : 2/11, mean age : 43+/-4 year, Atrial septal defect in 4, Ventricular septal defect in 1, Mitral regurgitation in 2, Tetralogy of Fallot in 1, and Aortic stenosis and Regurgitation with Mitral stenosis in 5 patients). The endothelial function was evaluated with the vasomotor response to acetylcholine and nitroglycerin by change of arterial diameter during the continous infusion of acetylcholin, from 10(-9) to 10(-6) molar concentration to the coronary artery and intracoronary injection of 200microg nitroglycerin after acetylcholine infusion. The infusion study was performed before and 10 days after surgery. For analysis of the role of oxygen free radical and lipid peroxidation in reperfusion injury, blood samples for malondialdehyde and neutrophil respiratory burst test(hydrogen peroxide amount of neutrophils) were obtained in pre-declamping of aorta and 5 min, 10 min, and 20 min after declamping of aorta from coronary sinus. RESULTS: 1) The vasoconstrictor response to acetylcholine, 10(-9) to 10(-6)M concentration, at proximal and distal left anterior descending coronary artery, were increased significantly in post-operation infusion study but there was no singnificant difference in vasodilator response to nitroglycerin. 2) The mean absorbance value of malondialdehyde(MDA) in pre-declamping and 5min, 10min, and 20min after reperfusion were 96+/-12, 73+/-12, 89+/-11 and 77+/-12, respectively. There was no significant difference in plasma MDA level and hydrogen peroxide amount of neutrophils after reperfusion(aortic declamping). CONCLUSION: These data suggest that endothelium dependent vascular relaxation is impaired in patients with open heart surgery and post-ischemic reperfusion injury may be responsible for the abnormal response. But we did not determine the role of lipid peroxidation and oxygen free radical in reperfusion injury.
