RESUMO
We report a rare case of the concurrent manifestation of central diabetes insipidus (CDI) and type 2 diabetes mellitus (DM). A 56 year-old man was diagnosed as a type 2 DM on the basis of hyperglycemia with polyuria and polydipsia at a local clinic two months ago and started an oral hypoglycemic medication, but resulted in no symptomatic improvement at all. Upon admission to the university hospital, the patient's initial fasting blood sugar level was 140 mg/dL, and he showed polydipsic and polyuric conditions more than 8 L urine/day. Despite the hyperglycemia controlled with metformin and diet, his symptoms persisted. Further investigations including water deprivation test confirmed the coexisting CDI of unknown origin, and the patient's symptoms including an intense thirst were markedly improved by desmopressin nasal spray (10 microg/day). The possibility of a common origin of CDI and type 2 DM is raised in a review of the few relevant adult cases in the literature.

Hyponatremia is the most common electrolyte disorder in hospitalized patients. Many studies documented that it was related to increased morbidity and mortality in patients with congestive heart failure, liver cirrhosis, and neurologic diseases. Although knowledge of hyponatremia has been cumulated, the optimal management of hyponatremia remains incompletely established in clinical practice because of the diversity of underlying disease states, and its multiple causes with differing pathophysiologic mechanisms. Since vasopressin receptor antagonists have unique aquaretic effect to selectively increase electrolytes-free water excretion, clinicians could apply a more effective method to treat hyponatremia. Tolvaptan has significant evidence that it improves serum sodium levels in patients with euvolemic or hypervolemic hyponatremia related with heart failure, cirrhosis or syndrome of inappropriate anti-diuretic hormone. Tolvaptan has acceptable safety and tolerability for long-term usage in chronic hyponatremia, and the beneficial effects on serum Na+ occurred in patients with both mild and marked hyponatremia.

This is a case of a sudden cardio-pulmonary arrest in a 29 year-old female, which occurred immediately after a large bolus infusion of propofol (100 mg) intravenously during dilatation and curettage. The arrest suddenly occurred, and the patient was eventually transferred to our emergency room (ER) on cardiopulmonary resuscitation. At that time, severe hyperkalemia up to 9.1 mEq/L and ventricular fibrillation were noted. Resuscitation in ER worked successfully with conversion of electrocardiograph to sinus rhythm, but this patient expired unfortunately. On view of this acute event immediately after the bolus injection of propofol accompanied without other identified causes, severe hyperkalemia induced by propofol was strongly assumed to be the cause of death. To our understanding with the literature survey, propofol as a cause of hyperkalemia has not been well described yet. Through this case, the relationship as a cause and an effect between propofol and hyperkalemia is suggested.

The risk of development of hypoglycemia increases during glycemic control in end-stage renal disease (ESRD) patients. We report the case that an ESRD patient on maintenance hemodialysis has experienced sustained hypoglycemia with a nateglinide. A 73-year old male ESRD patient on hemodialysis was admitted with exertional dyspnea and increased liver function test. On the 4th day after admission, he had mental change with his blood glucose level of 41 mg/dL. His mental state improved promptly after intravenous injection of 25 g of glucose. To prevent rebound hypoglycemia 10% glucose solution was continuously infused and nateglinide was discarded. However, he has had recurrent hypoglycemic attacks until the 6th day after admission, and thereafter there was no further hypoglycemic attack. On the 5th day of admission, when there was second hypoglycemic attack, the fasting insulin level was 31.62 U/mL, indicating that hypoglycemia was accompanied by insulin hypersecretion. In conclusion, we suggest that nateglinide may provoke a severe and sustained hypoglycemia in an ESRD patient on maintenance hemodialysis and its use might be avoided.

BACKGROUND: Being able to hydrolyze the majority of b-lactam antibiotics that are currently in use, extended-spectrum b-lactamases (ESBLs) pose a serious clinical problem. In order to solve this problem, it is recommended to use beta-lactam/beta-lactamase inhibitor instead of extended-spectrum cephalosporins. This study investigated the relationship between piperacillin/tazobactam use and ESBL-producing Klebsiella pneumoniae and Escherichia coli in stool colony. MATERIALS AND METHODS: A prospective study was performed in hemato-oncology department patients of Hanyang University Hospital. During the pre-intervention period of 3 months (Feb. 2005 to Apr. 2005), antibiotics were prescribed liberally. During the intervention period of 6 months (May. 2005 to Oct. 2005), use of the 3rd (4th) generation cephalosporins and carbapenems were restricted and piperacillin/tazobactam was recommended. All enrolled patients performed stool culture or rectal swab culture. ESBL confirmed by Double disk synergy test and commercial identification kit. Between the pre-intervention and intervention groups, acquisition rates of ESBL producing organisms were compared. RESULTS: 50 cases were enrolled in pre-intervention period and 112 cases were enrolled in intervention period. In intervention period, use of 3rd (4th) generation cephalosporins and carbapenems decreased from 27 daily define dose/1,000patient/days to 6.82 DDD/1,000patient/days, but use of piperacillin/tazobactam increased from 1.98 DDD/1,000patient/days to 5.66 DDD/1,000patient/days. The intestinal acquisition rate of ESBL producing organism decreased from 30% to 12%. There was no difference in overall mortality of infectious disease between two phase. CONCLUSION: Use of piperacillin/tazobactam instead of extended-spectrum cephalosporins reduces intestinal acquisition rate of ESBL producing K. pneumoniae and E. coli. Therefore, in order to decrease the number of ESBL producing organism, we recommend using piperacillin/tazobactam instead of using extended-spectrum cephalosporins.

Intravenous immunoglobulin (IVIG) therapy has been introduced to idiopathic dilated cardiomyopathy due to their antiviral and anti-inflammatory effects. But each study reported conflicting result and treatment regimen has not been clearly established. We experienced a case of 28-year-old woman with idiopathic dilated cardiomyopathy with severely depressed cardiac function. Its onset time was obvious within 1 month. Despite of conservative treatment of heart failure, sudden cardiac arrest was developed. We tried IVIG therapy, and her symptoms and cardiac function were improved after IVIG treatment.

Paraneoplastic limbic encephalitis is a rare disorder that is characterized by personality changes, irritability, depression, seizures, memory loss and dementia, and is commonly associated with small cell lung cancer. The cause is unknown but it is believed to be an autoimmune disorder that develops secondary to a carcinomatous process. We report a patient with the clinical feature consistent with limbic encephalitis. A 64-year-old women developed disorientation, memory loss and general weakness. She was diagnosed with NSCLC (adenocarcinoma) with a brain metastasis 1 year earlier and was treated with radiation and chemotherapy. Although the lung mass and brain metastatic lesions had improved, the brain T2-weighted MRI showed high signal intensity in the right temporal region. This lesion consisted of with limbic encephalitis and was negative to the other viral and immune markers. The patient's symptoms did not improve after steroid treatment. Our case demonstrated that a NSCLC (adenocarcinoma) also can be associated with paraneoplastic limbic encephalitis.

Tsutsugamushi disease (Scrub typhus) is an acute, febrile illness caused by Orientia tsutsugamushi, which is transmitted to humans through chigger bites. Leptospirosis, a febrile disease caused by various pathogenic Leptospira, and is acquired by exposure to contaminated water and soil. Both diseases have been the most common acute febrile diseases in the autumn in Korea for many years. Concomitant leptospirosis and scrub typhus is quite rare. We report a case of a coinfection with leptospirosis and scrub typhus in a 51-year-old male who presented with fever, abdominal pain and acute dyspnea. The patient was diagnosed with as acalculous cholecystitis, acute respiratory distress syndrome, and septic shock caused by the infection. This is the first case report of a coinfection with leptospirosis and scrub typhus in Korea.

The records of 14 patients with traumatic diaphragmatic rupture seen at Dongguk University Hospital from February 1992 through December 1995 were reviewed. Ten patients were male and four were female(M:F=2.5:1). The age distribution ranged from 17 to 73 years with the mean age of 41.7 years. The 14 patients included 12 who had blunt trauma(traffic accident 11, crushing injury 1) and 2 with penetrating diaphragmatic rupture(stab wound 2). Of those 12 blunt trauma, 7 patients(58.3%) were left sided and 5(41.7%) involved the right hemidiaphragm. The diagnosis was made preoperatively in 8 patients (57.1%) and during surgery in 6(42.9%). All right-sided injuries were repaired through a thoracotomy and left-sided defects were corrected through a laparotomy in 6, laparotomy and thoracotomy in 1. There were 2(14.3%) operative deaths that were caused by myocardial infarction and the sequelae of combined injuries.

Since 1981 there have been many clinical and experimental reports of venous skin flap, which was nourished solely by venous blood, or by arteria1 blood flowing through the venous network. But, the mechanism of survival has not been completely understood. Unfortunately, partial flap necrosis and unstable postoperative recovery course make surgeons hesitant in choosing the venous flap. In order to increase the survival of a venous flap, surgical delay procedure or increasing the number of draining veins have been successfully tried. Historically, tissue expansion has the same effect on skin vascularity as delaying the area The increase in the caliber of the blood vessels and adequate neovascularization of the expanded tissue can increase the size and vascularity of the flap while allowing primary closure of the donor defect. In order to investigate the survival pattern of expanded arterialized venous flap, the author conducted the following study. The arterialized venous flaps were divided into control and two experimental groups. The conventional nonexpanded arterialized venous flap of 5x5 cm in size was used as control group On experimental group I, preoperative tissue expansion was performed during 3 weeks, and then arterialized venous flap with the same size was made. On experimental group II, expanded arterialized venous flap with 10x10 cm in size was made. The mean survival rate of control, experimental group I and II was 81.2%, 98.8% and 99.1%, respectively. The angiogram of expanded flap showed dilatation of the vessels and neovascularization with tortuous vessels to the peripheral area of the flap. In conclusion, the survival of expanded arterialized venous flap was superior than that of conventional arterialized venous flap. The expanded venous flaps appear to be useful in producing large flaps, in decreasing marginal necrosis of the flap as well as minimizing donor defect.

The ideal breast reduction should create beautiful breasts with limited scars. Unfortunately, no surgeon has ever been able to produce such a result. Most recent breast reduction techniques tend to produce minimal breast scars and avoid the classic inverted-T incision. The vertical mammaplasty can be used in mild to moderate cases of breast reduction, producing consistently good, stable results with limited scars. This technique uses adjustable preoperative markings, an upper pedicle for the areola, and a central breast reduction with limited skin undermining. The shape of the breast is created by suturing of the gland and does not rely on the skin. The adjunctive use of liposuction in fatty breasts can be considered safe and efficient. We have performed reduction mammaplasty using the vertical mammaplasty technique in 12 patients. Overall number and extent of complications were small, and patient satisfaction was high for this procedures. The advantages of vertical mammaplasty technique compared with other methods are as follows ; 1. The markings are adjustable to nearly all patients. 2. Stable contours are produced because the gland is strongly sutured. 3. Few postoperative complications occur. 4. Limited scars(only vertical scars) are created 5. The procedure is easy to learn and perform.
