Arterial blood gas analysis has become an integral part of the clinical evaluation of the patient with known or suspected pulmonary disease. However, when the results of the measurements show arterial hypoxemia which is out of proportion to the clinical and X-ray evidence of lung disease, we may consider potential errors in measurement involving the blood gas analyzer or methods of blood sample storage. We experienced spurious hypoxemia in a patient with extreme leukocytosis (220.0 X 10(3)/mm3) secondary to leukemia. The degree of PaO2 decay was blunted by placing the blood on ice.

OBJECTIVE: Left ventricular hypertrophy is common and major complication in patients with end stage renal disease (ESRD), but pathogenesis is not clear. We have used echocardiography to evaluate influential factors and contractile performance according to the geometry of left ventricle. METHODS: We measured left ventricular mass, the extent of pericardial effusion and systolic function of left ventricle with M-mode and two dimensional echocardiography in 99 cases of ESRD from March 1993 to March 1996. RESULTS: 1) Body surface area and systolic blood pressure was higher in men than those in women. But, there was no difference in LV mass index or systolic function between the sex. 2) Among the 99 patients with ESRD, 89 cases (90%) had increased ventricular mass and 10 cases had normal ventricular mass. In the left ventricular hypertrophy groups, 60 cases had concentric hypertrophy, 29 cases had eccentric hypertrophy. 3) In patients with normal ventricular mass, hypertension and pericardial effusion were less frequent than in those with left ventricular hypertrophy. In patients with concentric hypertrophy, systolic blood pressure and body surface area were increased and serum albumin was decreased as compared to patients with eccentric hypertrophy. In patients with eccentric hypertrophy, duration of dialysis was increased. But, the result of Logistic analysis showed that systolic blood pressure and serum albumin were reliable factors for the geometry of left ventricle. 4) In patients with eccentric hypertrophy, LV mass index was significantly correlated with the concentration of serum alkaline phosphatase and phosphate. But, in patients with concentric hypertrophy, any factors were not correlated with LV mass index. 5) Systolic performances such as ejection fraction and fractional shortening were decreased in patients with eccentric hypertrophy. 6) The pattern of left ventricular hypertrophy was not different among non-dialysis group, hemodialysis group and CAPD group. CONCLUSION: In patients with ESRD, left ventricular hypertrophy is a common complication and most common hypertrophic type is concentric hypertrophy. The geometry of left ventricular hypertrophy may be influenced by various factors such as systolic blood pressure and serum albumin concentration and influence on the systolic performance of left ventricle. Further study for the geometry of left ventricle and the prognosis may be necessary for the improvement of cardiovascular complications in patients with ESRD.

Gastric polyps are uncommon. The incidence of gastric polyps has been reported between 0.4% and 2.0%. Two histologically distinct forms of gastric polyps are hyperplastic polyps and adenomatous polyps. Hyperplastic polyps are multiple in up to a half of cases. When the polyps number is more than 50, the term "Hyperplastic polyposis" is applied and such cases are even more rare. Polypoid lesions of the stomach have heen reported in many of the polyposis syndromes, such as Familial polyposis coli, Gardners syndrome, Peutz-Jeghers syndrame, Juvenile polyposis and Cowdens disease. Only 1 case of gastric hyperplastic polyposis associated with colonic hyperplastic polyposis has been reported. The patient under study is not included in any polyposis syndrome and has no familial tendency, We report a case of gastric hyperplastic polyposis with colonic hyperplastic polyposis with literatures reviews.

BACKGROUND AND PURPOSE: Upper respiratory infection (URI), including influenza, may exacerbate the symptoms of myasthenia gravis (MG), which is an autoimmune disease that causes muscle weakness. There is also concern that the influenza vaccine may trigger or worsen autoimmune diseases. The objective of this study was to determine the impacts of influenza infection and vaccination on symptom severity in MG patients. METHODS: Patients diagnosed with MG were enrolled from 10 university-affiliated hospitals between March and August 2015. Subjects completed a questionnaire at the first routine follow-up visit after enrolling in the study. The patient history was obtained to determine whether a URI had been experienced during the previous winter, if an influenza vaccination had been administered before the previous winter, and whether their MG symptoms were exacerbated during or following either a URI or vaccination. Influenza-like illness (ILI) was defined and differentiated from the common cold as a fever of ≥38℃ accompanied by a cough and/or a sore throat. RESULTS: Of the 258 enrolled patients [aged 54.1±15.2 years (mean±SD), 112 men, and 185 with generalized MG], 133 (51.6%) had received an influenza vaccination and 121 (46.9%) had experienced a common cold (96 patients) or ILI (25 patients) during the analysis period. MG symptoms were aggravated in 10 (40%) patients after ILI, whereas only 2 (1.5%) experienced aggravation following influenza vaccination. The rate of symptom aggravation was significantly higher in patients experiencing an ILI (10/25, 40%) than in those with the common cold (15/96, 15.6%, p=0.006). CONCLUSIONS: The results of this study suggest that the potential risk of aggravating autoimmune disease is higher for ILI than for influenza vaccination, which further suggests that influenza vaccination can be offered to patients with MG.

BACKGROUND: Consultation and referral are important characteristics of modern medicine which has become more segmented and more specialized. In particular, they give essential value to family practitioners to coordinate patients accordingly for proper care. This study analyzed the referred patients in family practices under Cheonan practice based-research network (CPBRN). METHODS: The data was collected via questionnaire in ten family clinics under CPBRN system during the four weeks from June 15, 2006 to July 12, 2006. RESULTS: The total number of referred cases was 103 (0.7%) out of a total of 14,466 office visits. Among the total, 68.9% of referred cases was physician-drived and 31.1% was patient-requested. The reason for referral were 'to get a second opinion of specialist' (34), 'high severity' (20), 'lack of examination tool' (18), 'lack of skill' (10) and 'no response to treatment' (2) in physician-drived cases, whereas in patient-requested cases, they were 'request for advanced hospital' (26) and 'want to meet specialist' (2). The patients were referred to tertiary hospital in 66.7%, secondary hospital in 15.9%, and other specialists of primary setting in 10.1%. Overall, 66.7% of the referred hospital was located in the city area. The main health problems of referred patients was divided into 'gastrointestinal' (17.5%), 'musculoskeletal' (13.6%), 'dermatology' (10.7%) and so on. The speciality consulting physicians were 'internal medicine' (34%), 'pediatrics' (13.6%), and 'orthopedic surgery' (10.7%) specialists. CONCLUSION: The referral rate of family practice in Korea was 0.7%. The main reason for referral was 'to get a secondary opinion of a specialist'. The most common referral problem was 'gastrointestinal'. 'Internal medicine' was the most frequently consulted specialty.
