Bartter syndrome is a renal tubular defect in electrolyte transport characterized by hypokalemia, metabolic alkalosis, hyperreninemia, hyperaldosteronism, normal blood pressure, and other clinical symptoms. As a clinical and genetical heterogeneous disorder, this syndrome can be classified into two clinical variants, antenatal Bartter syndrome and classic Bartter syndrome according to the onset age. Nephrocalcinosis is common in antenatal Bartter syndrome, but is rare in classic Bartter syndrome. It can also be classified into five genetic subtypes by the underlying mutant gene, all of which are expressed in the tubular epithelial cells of the thick ascending limb of the loop of Henle. Patients with Bartter syndrome type 1, 2 and 4 present at a younger age than classic Bartter syndrome type 3. We have experienced a case of Bartter syndrome with nephrocalcinosis in a 42-year-old woman diagnosed by biochemical and radiologic studies. We had successful response with potassium chloride and spironolactone.

Spinal cord stimulation (SCS) is a reliable clinical option for treatment of refractory chronic pain. It is known to be effective method for treating sympathetic pain, failed back surgery syndrome, and complex regional pain syndrome etc. The devices and implantation techniques for SCS are already highly developed and continuously improving, but there are some complications that can not be corrected easily. Lead migration is the most common complication after SCS. It can cause failure of SCS that can make discomfort to patients. Here we describe our experience of lead migration in implanted SCS which was inserted to a patient with complex regional pain syndrome patient.

Isoniazid is one of the most commonly used antituberculosis drug. Acute into xication is characterized by repetitious convulsions, high anion gap metabolic a cidosis and coma. The basis of theraphy consists of parental pyridoxine admi nistration in a dose equivalent to that of isoniazid ingested. Here we present a case of seizure and metabolic acidosis due to only renal adjustment dosage of Isoniazid in an elderly woman.

We report oliguric mannitol-induced acute kidney injury (AKI) early treated by continuous renal replacement therapy. A 70-year-old woman was admitted to the Department of Neurology with diagnosis of acute intracranial hemorrhage. Mannitol was infused for intracranial pressure control. At admission third day, urine output was abruptly decreased to 57 ml during first 6 hours and blood urea nitrogen (BUN) and serum creatinine was increased to 54.2 mg/dL and 5.3 mg/dL respectively. Plasma osmolality was 340 mOsm/kg and osmolar gap was 70. Mannitol was immediately withdrawn and continuous renal replacement therapy (CRRT) was performed to remove mannitol rapidly. Urine output was increased 6 hours later after continuous veno-veno hemodiafiltration (CVVHDF) start. BUN and creatinine was decreased to 21.4 and 1.2 mg/dL at admission ninth day. Mannitol can develop oliguric AKI and CRRT may be of more benefit than conventional hemodialysis in the case of increased intracranial pressure.

The cirrhotic patients with ascites present unique challenge to the renal caregiver. Hydrothorax in a cirrhotic patient treated with PD poses a diagnostic dilemma. Proposed mechanisms for the development of a pleuro-peritoneal communication include congenital diaphragmatic defects, acquired weakening of diaphragmatic fibers caused by high intra-abdominal pressures during peritoneal dialysis, and impairments in lymphatic drainage. Pleural fluid analysis and diagnostic imaging assist in differentiation from other causes of pleural effusion. We report a case of hydrothorax in a compensated cirrhotic patient after recent introduction to peritoneal dialysis.

OBJECTIVES: The aim of this study was to explore the changes of bronchoscopic features according to epidemiologic change of lung cancer. METHODS: We performed a retrospective review of the clinical characteristics of 1,139 lung cancer patient who underwent bronchoscopy at Kosin University Hospital from January 2000 to December 2010. RESULTS: The age of patients increased significantly during the last decade (P < 0.001). The most common histological type was adenocarcinoma (38.1%), followed by squamous carcinoma (35.7%) and small cell carcinoma (15.3%). There was an increasing incidence of adenocarcinoma over the time (P < 0.001). Bronchoscopic feature were divided into two classes; central type, peripheral type. The peripheral type was predominant (62.3%). The proportion of peripheral type has been increased in process of time (49.7% vs. 63.7% vs. 73.7%; P < 0.01). Among the major histopathologic type of lung cancer, adenocarcinoma (81.3%) and unclassifiable non-small-cell lung cancer (73.4%), small cell carcinoma (56.9%) were associated with preferential occurrence of peripheral type. Squamous cell carcinoma of the lung more often arised in central type (59%). However, the proportion of peripheral squamous cell carcinoma has been increased. On the subgroup analysis, the median survival time of peripheral type with adenocarcinoma and small cell carcinoma were longer than central type (P < 0.05). CONCLUSIONS: The age of the lung cancer patients at diagnosis was getting older. The most frequent histopathologic type was adenocarcinoma. The proportion of peripheral type lung cancer gradually increased over the time. The survival time of peripheral type lung cancer was longer than central type.

Tsutsugamushi disease (Scrub typhus) is an acute febrile illness caused by infection with Orientia tsutsugamushi and characterized by focal or disseminated vasculitis, which may involve the lungs, heart, liver and central nervous system. Tsutsugamushi meningitis are reported worldwide, but central diabetes insipidus associated with CNS involvement have not been reported. A 53-year-old female diagnosed with tsutsugamushi disease showed polyuria during therapy with doxycycline. After injection of vasopressin, urine output was decreased and urine osmolarity was increased. So, we diagnosed as central diabetic insipidus. We report a case of central diabetes insipidus occurring during therapy for tsutsugamushi disease.

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is characterized by congenital aplasia of the uterus and the upper part of the vagina in women showing normal development of secondary sexual characteristics and a normal 46, XX karyotype. MRKH syndrome usually remains undetected until the patient presents with primary amenorrhea despite normal female sexual development. MRKH syndrome is the second frequent cause of primary amenorrhea. There have been several reports concerning gynecologic disease in MRKH syndrome, but there has been few case about MRKH syndrome with gonadal agenesis. We report an exceptional association between bilateral ovarian agenesis 46,XX and MRKH syndrome. A 27-year-old woman who presented with primary amenorrhea and absence of secondary sexual development. She had normal, 46XX karyotype, but no upper vagina, uterus and both ovary. And there was no urogenital and skeletal malformation. She was diagnosed as the atypical form of MRKH syndrome (bilateral gonadal agenesis 46 XX).

A 77-year old woman was referred to hospital with dyspnea and chest dull pain for 5 months. The chest radiograph showed a mass located in the mediastinum. Trachea was deviated to right side. Chest computed tomography showed an enhancing large mass at the middle mediastinum. Endobronchial ultrasonography showed hyperechoic mediastinal mass. We performed endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA). Histologic finding was thyroid tissue with a benign looking papilla. Ectopic thyroid is an uncommon embryological aberration characterized by the presence of thyroid tissue in a site other than in its usual pretracheal region. It occurs along the path of descent of the developing thyroid primodium from the foramen cecum. It is extremely rare for mediastinal ectopic thyroid tissue diagnosised by EBUS-TBNA, so we report here on a case of mediastinal ectopic thyroid and we review the relevant medical literature.

Pulmonary embolism is caused by various conditions including genetic and acquired factors, and among them, C and S protein deficiency are known as a cause of pulmonary embolism although their incidences are low. Apical hypertrophic cardiomyopathy is known as a subtype of hypertrophic cardiomyopathies which was reported to be a cause of diastolic heart failure or thromboembolism by activating coagulation system, and this may have an effect on developing pulmonary embolism. We report this since we experienced a case of both C and S protein deficiencies in a patient with apical hypertrophic cardiomyopathy who was diagnosed as pulmonary embolism and has been examined to find the cause of the disease.
