This study includes 19 cases of complicated low extremity injury to whom underwent microvascular free-tissue transfer in cases of open comminuted fracture, osteomyelitis, and vascular compromise or extensive soft tissue defect from Nov. 1994 to July 1997. The average time after injury to coverage was 25 days. The nineteen patients underwent a total of nineteen free tissue transfers primarily, and eighteen (94.7 per cent) of the transfers survived. Major complications were encountered recurrent failure of the free tissue transfer in one patient and partial necrosis in the other flap, which were successfully treated by flow-through radial forearm free flap and distally based superficial sural artery flap respectively. Two patients were sustained below knee amputation, one above knee amputation, despite of survival of flaps. This reveals limb salvage in 84 percent. The microvascular reconstruction is a versatile and reliable methods in complicated cases after severe trauma. Free tissue transplantation should be considered as a primary treatment in such complicated cases.

The metabolic syndrome is a constellation of interrelated risk factors of metabolic origin that appear to directly promote the development of cardiovascular disease. The syndrome is also strongly associated with type 2 diabetes mellitus or the risk for this condition. In this article, we propose preventive measures for the metabolic syndrome through reviewing recent clinical studies for diabetes prevention. Randomized, controlled trials conducted in 3 countries have established that the maintenance of modest weight loss through diet and physical activity reduces the incidence of type 2 diabetes in high-risk persons by about 40% to 60% over 3 to 4 years. Drug therapy to prevent or delay diabetes appears to be much less beneficial than lifestyle modification. The Diabetes Prevention Program shows that interventions that prevent diabetes will also reduce the development of the metabolic syndrome. Consequently, lifestyle interventions should be primarily considered for the prevention of the type 2 diabetes and metabolic syndrome.

Obesity is a chronic disorder that requires a life long effort for the successful treatment. Although various pharmacological and surgical treatments have been developed, a dietetic therapy is still the basic therapeutic tool for the management of obesity. This article briefly reviews the basic concepts, efficacy and side effects of the diet modalities that have been recently used in obesity treatment.

As our population ages, so grows the amount of medical expenditures. In the future, elderly people will be better organized, more assertive and have higher expectations of their quality of life. More advanced health technologies have been developed with potential harm as well as beneficial effectiveness. We should provide the patients with health technologies with high scientific evidences. Randomized control trials (RCTs) provide the highest level of scientific evidence, but cannot always be performed because of ethical, practical or financial limitations, and do not always reflect what occurs in real clinical practice. However, patient registries can be used to evaluate patient outcomes through prospective evaluation of a structured collection of clinical information. Therefore, patient registries can complement RCTs.

Background: This study was designed to determine whether presynaptic receptor blockade could be differentiated from postsynaptic receptor blockade by examining the effect of increasing frequencies of indirect stimulation on partial twitch depression in vitro rat phrenic nerve hemidiaphragm preparations. Methods: After isolating rat phrenic nerve hemidiaphragm preparation, T200/T1 ratio (twitch height of the 200th stimuli divided by that of the 1st stimuli) at frequencies of 0.2, 0.5, 1.0, and 2.0 Hz using a drug concentration which provided approximately 20% twitch depression at 0.1 Hz was calculated. To compare T200/T1 ratios with TOF ratios, 2.0 Hz TOF response was measured immediately after 200th stimuli at either frequency of stimulation. Results: Hexamethonium caused a marked decrease in T200/T1 ratio at 0.5~2.0 Hz of stimulation, whereas alpha-bungarotoxin caused no change in T200/T1 ratios at up to 2.0 Hz of stimulation. The T200/T1 ratios produced by d-tubocurarine, vecuronium, mivacurium, and rocuronium located intermediate between alpha-bungarotoxin and hexamethonium, however significant differences among four drugs were found at 2.0 Hz. The propensity for decrease in T200/T1 ratios at 2.0 Hz might differ from this study: hexamethonium >d-tubocurarine >rocuronium >mivacurium = vecuronium >alpha-bungarotoxin. T200/T1 ratios at 2.0 Hz were not different from TOF ratios. Conclusions: When the observed effects in this study were provided with result of alpha-bungarotoxin acting predominantly at postsynaptic receptors and hexamethonium acting predominantly at presynaptic receptors, the effects of nondepolarizing muscle relaxants at each binding site could be differentiated by examining the T200/T1 ratios at 2.0 Hz.

The Committee of Education of the Korean Diabetes Association discussed the need to develop the Diabetes Education Recognition Program. In 2011, the current certification program was reviewed and a survey was conducted to improve the Diabetes Education Recognition Program. This improved program will be a standard for qualified diabetes education for diabetes educators and institutes, and will ultimately become a national standard for diabetes education.

To classify the causes of hypogonadotropic hypogonadism in Korean patients, and to improve the endocrinologic evaluation for the disease, we retrospectively studied the clinical findings and result of combined pituitary stimulation test in 35 patients with hypogonadotropic hypogonadism. The following results were obtained.1) The ratio of male to female was 1.3:1, and the 50% of male patients was under 20 years of age and the 20% of female patients in 30th decades. 2) The chief complaints of male patients on the admission were the failure of secondary sexual characteristics(95.0%) and loss of hair(5.0%), those of female patients were amenorrhea(46.7%), infertility(26.7%), failure of secondary characteristics(13.3%) and loss of hair(13.3%). 3) The causes of male hypogonadotropic hypogonadism were craniopharyngioma(35.0%), idiopathic(30.0%), Kallmann's syndrome(15.0%), pituitary adenoma(10.0%) and germinoma(5.0%), and those of female hypogonadotropic hypogonadism were prolactinoma(13.3%), Sheehan's syndrome(26.6%), pituitary adenoma(6.7%), tuberculous granuloma(6.7%), germinoma(6.7%), idiopathic hypogonadotropic hypogonadism(40.0%).4) The responses of LH and FSH to GnRH test were absent or markedly blunted in diffuse pituitary diseases such as pituitary tuberculous granuloma, pituitary macroadenomas, Sheehan's syndrome. However those were also absent or blunted in Cushing's disease and hypothalamic disease such as Kallmann's syndrome, germinoma, craniopharyngioma, idiopathic hypogonadotropic hypogonadism. 5) The responses of LH, FSH increased after repeated injection of GnRH in a patient with germinoma. 6) In diffuse destructive pituitary diseases such as Sheehan's syndrome, nonfunctioning macroadenomas, tuberculous granuloma, large prolactinoma, the combined deficiency of pituitary hormones other than gonadotropins was observed. 7) In many cases with hypothalamic diseases, the combined defects of pituitary hormone response were also seen.These data suggest that GnRH test is not always useful to localize the lesion between pituitary and hypothalamus, and combined pituitary stimulation test revealed defects of pituitary hormones other than gonadotropin in various hypothalamic diseases.Therefore repeated GnRH test would be useful for the differential diagnosis, and CRH test and GRH test would be necessary to demonstrate whether pituitary abnormality is present.
