Osteoporosis, a disease characterized by low bone mass and microarchitectural deterioration of bone tissue leading to enhanced bone fragility and fracture risk, is a major public health problem. The diagnostic methods for osteoporosis include simple radiography, bone scan, DXA (Dual energy X-ray Absortiometry) and biochemical markers of bone turnover. Optimal treatment and prevention of osteoporosis require modification of risk factors, particularly smoking cessation, adequate physical activity, and attention to diet, in addition to pharmacologic intervention. The estrogens and raloxifene both prevent bone loss in postmenopausal women, and the estrogens probably also decrease the risk of first fracture. There is good evidence that raloxifene prevents further fractures in postmenopausal women who already have had fractures and some evidence that estrogen does as well. Bisphosphonate prevents bone loss and reduces fractures in healthy and osteoporotic postmenopausal women and in osteoporotic men as well. Risedronate is more potent and has fewer side effects than alendronate and reduces the incidence of fractures in osteoporotic women. Calcitonin increases bone mineral density in early postmenopausal women and men with idiopathic osteoporosis, and also reduces the risk of new fractures in osteoporotic women. All of the agents discussed above prevent bone resorption, whereas teriparatide and strontium increase bone formation and are effective in the treatment of osteoporotic women and men. New avenues for targeting osteoporosis will emerge as our knowledge of the regulatory mechanisms of bone remodeling increases, although issues of tissue specificity may remain to be addressed.

Transcranial cerebral oximetry has been successfully used in a variety of neurosurgical conditions, primarily those associated with disturbed cerebral circulation. It has been also used in intraoperative monitoring of aortic dissection and surgical procedures performed under deep hypothermia and circulatory arrest. During disending aortic arch exposure, sudden cerebral oxygen saturation change from 63% to 48% was detected. After therapeutic bypass, cerebral oxygen saturation was increased to 65%. During aortic arch repair, deep hypothermic circulatory arrest with retrograde cerebral perfusion was applied for 130 min and cerebral oxygen saturation slowly decreased from 65% to 52%. Patient was discharged from hospital without neurologic complication and cognitive funtion disturbance.

Cheilitis granulomatosa is a macrocheilia having a sudden onset and a progresaive eourse that terminates in chronic enlargement of the lips. Labial enlargement can occur alone or in combination with intermittent facial paralysis and fissured tongue. The traid of abnormalities has been termed the Melkersaon-Rosenthal syndrome. The term, cheilitis granulomatosa, is now generally accepted as the description of the labial conditian with or without the other components of the triad. We have experiegced a case of cheilitis granulomatosa in a 23-year-old man and excellent result were obtained after local triamcinolone acetonide injections. On the first examination, the upper lip was estimated at approximately twice the normal size and the tongue was moderatedly furrowed. The consistency was elastic, but firm due to the nan pitting edema of the entire upper lip. We have treated him with intralesional injections of triamcinolone acetonide. Total injeetions were fifteen times in 6 months period. After the treatment, climcally ohaerved ehanges eonsisted of a decrease in lip volume, diminished edema plus a gradual softening of lip texture.

The Palmaris longus tendon is important not because of its function but because of its usefulness as a donor tendon. Variations in the palmaris longus muscle ar elfrequent and the most common variation of the muscle is its absence. The incidence of absence of this muscle varies in different racial groups. Reinmann and his coworkers found the palmaris longus muscle absent in 12.9% of in their 1,600 limbs surgery. We have experiened 307 cases of palmaris longus graft surgery and found that there were 4 cases of absence of the palmaris longus tendon. We examined 2,000 limbs of Korean to see the presence of the palmaris longus muscle. Among 1,000 persons, the muscle was absent bilaterally in 11 persons(1.1%). It was absent unilaterally in 32 persons(3.2%). The probability that the muscle is absent in any single limb is 2.7%. There was no significant differences in the incidence of absence by sex or right and left side.

Purpose: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) risk calculator is useful in predicting postoperative adverse events. However, its accuracy in specific disorders is unclear. We validated the ACS NSQIP risk calculator in patients with gastric cancer undergoing curative laparoscopic surgery. Materials and Methods: We included 207 consecutive early gastric cancer patients who underwent laparoscopic gastrectomy between January 2018 and January 2019. The preoperative characteristics and risks of the patients were reviewed and entered into the ACS NSQIP calculator. The estimated risks of postoperative outcomes were compared with the observed outcomes using C-statistics and Brier scores. Results: Most of the patients underwent distal gastrectomy with Roux-en-Y reconstruction (74.4%). We did not observe any cases of mortality, venous thromboembolism, urinary tract infection, renal failure, or cardiac complications. The other outcomes assessed were complications such as pneumonia, surgical site infections, any complications requiring re-operation or hospital readmission, the rates of discharge to nursing homes/rehabilitation centers, and the length of stay. All C-statistics were <0 and the highest was for pneumonia (0.65; 95% confidence interval: 0.58–0.71). Brier scores ranged from 0.01 for pneumonia to 0.155 for other complications. Overall, the risk calculator was inconsistent in predicting the outcomes. Conclusions The ACS NSQIP surgical risk calculator showed low predictive ability for postoperative adverse events after laparoscopic gastrectomy for patients with early gastric cancer. Further research to adjust the risk calculator for these patients may improve its predictive ability.

Basal cell epithelioma arising from epidermis and its appendages is a common skin tumor. But multiple occurence of basal cell epitheliomas and that of arising in an epidermal nevi are extremely rsre. Since the first report by Toyama and Kojima in 1937, only few cases were reported in the world literatures. We observed a case of multiple basal cell epitheliomas arising in an epidermal nevi in a 54-year-old female patient who had rhomboidal verrucous patch on the right side of the cheek and arciform erythematous verrucous eruption from the right side of the eyebrow to the lower eyelid. Clinical features were not compatible with any type of basal cell epithelioma. But histological finding revealed basal cell epithelioma with epidermal nevi. Literatures were briefly reviewed.

Experiments were performed to investigate the effects of pinealectomy on the renin-angiotensin system in Sprague-Dawley rats. The results obtained were as follows. 1) There was no differences of systolic blood pressure, heart rate, water intake, and plasma electrolytes between pinealectomized and sham-operated rats. 2) Renin activity in plasma and pituitary gland did not differ in two experimental groups. 3) The pituitary gland contained the renin activity of about 50pg AI/hr/mg of wet weight. The results suggest that the pineal gland has no correlation with cardiovascular and renin-angiotensin system.

Six cases of lunate dislocation were treated in the departments of orthopaedic surgery, Hangang Sacred Heart Hospital and Kangnam Sacred Heart Hospital, Hallym College during the period from March 1, 1978 to August 31, 1982. The results were as follows; l. Among the total 6 cases, two cases had lunate dislocation only and the other four had associated injuries of the same wrist joints. 2. Marupulative reduction was successful in only one case. Five cases were treated by open reduction, and for four of them internal fixation was tried. 3. Postoperative roentgenograms showed acceptable reductions in all cases except one which redislocation occurred. This case showed lunate dorsiflexion instability and was treated with extensor carpi radialis longus tenodesis. 4. The cases with pure lunate dislocation yielded better functional recovery than those with associated carpal injuries.
