BACKGROUND: Although hypochlorhydria, hypergastrinemia and antiparietal cell antibody have been well documented in the patients with hyperthyroidism, a cause of hypochlorhydria or hypergastrinemia is unknown at the present time. Therefore, in order to clarify an inhibitory mechansim of gastric acid secretion in the patients with hyperthyroidism, interrelationship among hypochlorhydria, hypergastrinemia and antiparietal cell antibody was investigated in this study. METHODS: The gastric secretory function, fasting and postprandial plasma concentrations of gastrin and titer of antiparietal cell antibody in the plasma were determined in the patients with hyperthyroidism and normal subjects. Immunoblot analysis was performed to identify the gastric membrane protein, a possible gastric antigen to antiparietal cell antibody. Using a immunocytochemical technique with electron microscopy, intracellular structure of the parietal cell reacted with antiparietal cell antibody was observed. RESULTS: The basal and pentagastrin-stimulated maximal acid output were reduced in the patients with hyperthyroidism. The fasting and postprandial plasma concentrations of gastrin were markedly elevated in the patients. The plasma gastrin concentration in the patients with the antiparietal cell antibody was higher than that of the norrnal subjects as well as the patients without the antibody not only in the fasting state but also in the postprandial state. However, the plasma gastrin concentration of the patients without the antiparietal cell antibody was elevated in the fasting state only. There was no difference in the gastrin content of the antral mucosa between the norrnal subjects and the patients. The antiparietal cell antibody was detected in 5 (38.5 %) out of 13 patients by using the indirect immunofluorescence method. Patient IgG dose-dependently inhibited rabbit gastric H (+),K (+)-ATPase activity. Among proteins of the rabbit gastric mucosa membrane, four high molecular weight proteins (91, 140, 170 and 210 K dalton) were reacted to the patient IgG. The patient IgG positive peroxidase-antiperoxidase (PAP) activity was electron microscopically detected on the intracellular cannalicular membrane of the parietal cell CONCLUSION: We conclude that hypochlorhydria and hypergastrinemia in the patients with hyperthyroidism are partially related to the antiparietal cell antibody and that the antigen to the antiparietal cell antibody may be H (+),K (+)-ATPase in the intracellular canalicular membrane of the parietal cell.

Infectious complications such as wound infection and intra-abdominal abscess are rarely fatal, but perplexing to both patients and surgeons, and still remain asserious problem after appendectomy in about 5% of the patients. To be helpful to reduce post-appendectomy complications, authors retrospectively analyzed 229 cases of appendectomy performed during the period of one year, from January 1 through December 31, 1995, to find out contributing factors to the post-appendectomy infectious complications such as wound infection or intra-abdominal abscess. The results were as follows. 1) Infectious complications are more common in patients with four or more days of symptom. 2) Infectious complications are more common in patients with complicated appendicitis such as gangrenous or perforated appendicitis. 3) Preoperative antibiotics are helpful to prevent infectious complications in cases of complicated appendicitis. 4) There is no difference in the incidence of infectious complications between the immediate operations and overnight delayed operations in patients who were admitted in the late evening or at night. 5) There is no difference in the incidence of infectious complications between operators: staff surgeons who exclusively operated on patients with complicated appendicitis and residents(with or without supervision of staff surgeons) who mostly operated on patients with simple appendicitis. This means technical superiority has its role in preventing infectious complications. Early diagnosis and operation before the gangrenous change or perforation are warranted. Preoperative antibiotics are effective in cases of complicated appendicitis, but not in cases of simple appendicitis. But the lack of objective criteria to decide complicated appendicitis before the operation remains problem, and prospective study to solve this problem is needed. Technical perfectness is required to protect the wound and to remove the appendix without contamination. Preventive measures are also important to prevent the infectious complications in cases of inevitably contaminated wounds or inta-abdominal spaces.

Thrombotic thrombocytopenic purpura (TTP) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, fever, and variable abnormalities in renal function and mental status. The pathogenesis of TTP is related to an inhibitor or deficiency of the von Willebrand factor (vWF)-cleaving protease (a disintegrin and metalloprotease with thrombospondin type 1 repeats; ADAMTS-13) that cleaves the large vWF multimers. Uncleaved, large vWF molecules are present in TTP and induce thrombosis in small vessels. Even though plasma exchange was proven effective in TTP, 20-40% of the cases showed refractory to plasma exchange. We describe a 41 years old female with plasma exchange refractory TTP who was completely recovered from anemia, thrombocytopenia, and accompanying symptoms following splenectomy.

OBJECTIVES: In the treatment of schizophrenia, treatment compliance is an important prognostic factor. As insight has a significant impact on treatment compliance, an appropriate assessment of insight is essential in the treatment of schizophrenia. This study examined the reliability and validity of the Korean version of Birchwood Insight Scale (BIS). METHODS: Fifty seven adult patients diagnosed with schizophrenia according to DSM-5 were recruited from a university hospital. They were evaluated using the Positive and Negative Syndrome Scale (PANSS), The Scale to Assessment Unawareness of Mental Disorder (SUMD) and BIS. Explorative factor analysis was performed to examine the construct validity of the Korean version of BIS. Concurrent validity was evaluated by a comparison with the PANSS G12 item and SUMD. The test-retest correlation was evaluated to examine the test-retest reliability. Multiple regression analysis was performed to examine the variables affecting insight. RESULTS: Explorative factor analysis showed that the Korean version of BIS was composed of 2 factors, which are ‘Awareness of symptoms’ and ‘Awareness of illness and need for treatment.’ The Korean version of BIS was reliable in terms of the internal consistency. Concurrent validity with the PANSS G 12 item and SUMD was statistically significant. The test-retest reliability was also statistically significant. Multiple regression analysis showed that the PANSS negative factor affects the BIS score, indicating that negative symptoms of schizophrenia may impair insight of the illness. CONCLUSION: This study suggests that the Korean version of BIS is a valid and reliable tool for assessing the insight of patients with schizophrenia.

Popliteal artery compression rarely occurs after posterior cruciate ligament (PCL) reconstruction using the tibial inlay technique that allows for direct visualization of the surgical field. However, we experienced a popliteal artery compression after PCL reconstruction performed using the technique, which eventually required re-operation. Here, we report this rare case and discuss reasons of popliteal artery compression.

A 44-year-old male presented with a month history of exertional dyspnea and dizziness. A peripheral blood smear revealed a pancytopenia with 3% of blasts. We were not able to obtain a bone marrow aspirate, but a biopsy specimen showed hypercellularity, proliferation of trilineage cell lines (panmyelosis) with extensive myelofibrosis, and clusters of immature cells at the paratrabecular area. After remission induction therapy with idarubicin 12mg/m2 (D1-3) and cytosine arabinoside 100mg/m2 (D1-7), the bone marrow blast count was decreased, but the marrow fibrosis and pancytopenia persisted. Peripheral blood stem cell transplantation from his HLA-matched brother was performed after administering fludarabine 30mg/m2 for 5 days and busulfan 3.2mg/kg for 2 days. Early engraftment occurred and the bone marrow reticulin fibrosis disappeared. Full-donor chimerism was demonstrated at day 22 by performing short tandem repeats analysis and this was maintained for 1 year. The patient has survived 20 months after transplantation without any complication.

BACKGROUND: Particulate matter may be toxic to human tissue. Ambient air particulate matter < or =10micrometer in aerodynamic size (PM10), which changes under different environmental conditions, is a complex mixture of organic and inorganic compounds. The Asian dust event caused by meteorological phenomena can also spread unique particulate matter in affected areas. We evaluated production of ROS, TGF-beta, fibronectin, and NF kappa B by exposing normal epithelial cells to Asian dust particulate matter. METHODS: Bronchial epithelial cells were exposed to 0, 50, 100microgramg/ml of a suspension of PM10 for 24 h. ROS were detected by measurement of DCF release from DCF-DA by FACScan. TGF-beta, fibronectin, and NF kappa B were detected by western blotting. RESULTS: PM10 exposure increased the expression of TGF-beta, fibronectin, and NF kappa B. ROS production and TGF-betalevels were significantly higher with 50 or 100microgram/ml PM10. Fibronectin and NF kappa B production were significantly higher after 100microgram/ml of PM10. CONCLUSION: PM10 from Asian dust particles might have fibrotic potential in bronchial epithelial cells via ROS induction after PM10 exposure.
