2.Classification and antibiotic sensitive of caused bacterium in some cases of pneumonia
Journal of Practical Medicine 2004;471(1):35-39
82 cases of pneumonia patients in the community and 3 cases at the hospital aged 62 in average, randomly collected were diagnosed bacteriologically using the samples gathered endoscopically which underwent a quantified culture and the antibiogramme was made by the method of dispersion on ager disk. Results showed that the pathogenes were mainly streptococci then gram(-) bacilli, sensitive with classic beta-lactam antibiotic group. The previous treatment by antibiotic before bacterical detection affected dramatically on the antibiotic sensitivity of pathogenic bacteria, especially with betalactam antibiotic, commonly used now a day.

3.Patient Stratification and Decision to Hospitalize Patients with Community-Acquired Pneumonia.
Journal of the Korean Medical Association 2007;50(10):868-876
Patients with community-acquired pneumonia can be divided into four groups, each with a list of likely pathogens and suggested empiric therapy accordingly. Patient classification is based on the assessment of place of therapy, the presence of cardiopulmonary disease, and the presence of modifying factors. The admission decision remains to be difficult and follows the prognostic scoring rules (the Pneumonia Patients Outcome Research Team, PORT) are widely using as admission criteria. Still clinicians use inconsistent admission criteria and often overestimate patients risk. In general, hospitalization is needed if patients have multiple risk factors for a complicated course. Admission to the intensive care unit is needed for patients with severe community-acquired pneumonia.

BACKGROUND: The incidence of penicillin-resistant streptococcus pneumoniae(PRSP) accounts for almost 70% of all pneumococcal pneumonia cases in Korea. It is still unclear as to whether the efficacy of penicillin or equally active beta-lactam agents is compromised in PRSP pneumonia. This study investigated the prevalence of PRSP in community-acquired pneumonia and its clinical course. METHODS: A total of 42 patients with community-acquired pneumococcal pneumonia were evaluated from July 1999 to May 2001. The cultured strains of Streptococcus pneumoniae were divided into susceptible, intermediately resistant, and resistant strains by an E-test, and the effect of the clinical course was investigated. RESULTS: From a total of 42 patients, 22 (52.4%) patients had an intermediate resistance (MIC 0.1-1 microgram/ml) and six (14.3%) showed a high resistance (MIC> or =2.0 microgram/ml) with current penicillin susceptibility categories. However, according to the classification of the DRSPTWG (Drug Resistant Streptococcus pneumoniae Therapeutic Working Group), there were 11 cases (26.2%) of intermediate resistance and no case of high resistance. Under empirical antimicrobial treatment, there was no difference in the clinical outcome between the penicillin susceptible and resistant group. CONCLUSION: The clinical outcome of PRSP pneumonia with empirical therapy was acceptable. These results suggest that the current MIC breakpoint for penicillin resistance in Streptococcus pneumoniae has been set at a very low level and penicillin resistance according to the NCCLS classification does not significantly influence the outcome of the empirical treatment for pneumococcal pneumonia.

PURPOSE: Acute respiratory infection, particularly pneumonia, is the most common cause of hospitalization and death among children in developing nations. This study aimed to investigate the characteristics of children and adolescents with pneumonia who visited Emergency Department (ED) in South Korea in 2012. METHODS: We analyzed National Emergency Department Information System (NEDIS) records from 146 EDs in South Korea for all pediatric patients aged ≤18 years who were diagnosed with pneumonia between January and December 2012. RESULTS: Among 38,415 subjects, the male-to-female ratio was 1:0.8. Patients aged <12 months comprised 18.0% of the study population; those aged 1 to 3 years, 54.4%; those aged 4 to 6 years, 16.8%; those aged 7 to 12 years, 7.4%; and those aged 13 to 18 years, 3.4%. Presentation rates were highest in April, followed by January, March, and May. The hospital admission rate was 43.5%, of which 2.6% were in intensive care units. The mortality rate was 0.02%. Based on the International Classification of Diseases, 10th Revision, diagnostic codes, the types of pneumonia according to cause were viral pneumonia (29.0%), bacterial pneumonia (5.3%), Mycoplasmal pneumonia (4.5%), aspiration pneumonia (1.3%), and pneumonia of unknown origin (59.3%). CONCLUSION: Despite the limited data due to the ED data from the NEDIS lacking laboratory results and treatment information, this study reflects well the outbreak patterns among children and adolescents with pneumonia. Our results provide a basis for future studies regarding ED treatment for children and adolescents with pneumonia.

PURPOSE: Understanding changes in pathogen and pneumonia prevalence among pediatric pneumonia patients is important for the prevention of infectious diseases. METHODS: We retrospectively analyzed data of children younger than 18 years diagnosed with pneumonia at 117 Emergency Departments in Korea between 2007 and 2014. RESULTS: Over the study period, 329,380 pediatric cases of pneumonia were identified. The most frequent age group was 1–3 years old (48.6%) and the next was less than 12 months of age (17.4%). Based on International Classification of Diseases, 10th revision diagnostic codes, confirmed cases of viral pneumonia comprised 8.4% of all cases, pneumonia due to Mycoplasma pneumoniae comprised 3.8% and confirmed cases of bacterial pneumonia 1.3%. The prevalence of confirmed bacterial pneumonia decreased from 3.07% in 2007 and 4.01% in 2008 to 0.65% in 2014. The yearly rate of pneumococcal pneumonia also decreased from 0.47% in 2007 to 0.08% in 2014. A periodic prevalence of M. pneumoniae pneumonia (MP) was identified. CONCLUSION: The increased number of patients with pneumonia, bacterial pneumonia, pleural effusion, and empyema in 2011 and 2013–2014 resulted from an MP epidemic. We provide evidence that the frequency of confirmed cases of bacterial pneumonia and pneumococcal pneumonia has declined from 2007 to 2014, which can simultaneously reflect the effectiveness of the pneumococcal conjugate vaccine.

BACKGROUND: One of the factors that affect the anesthetic risk is preoperative status especially in geriatric patients. So we studied about followings; 1) Can we use APACHE scoring index when we assess the physical status of geriatric patients preoperatively? 2) Is it meaningful in saying the risk of anesthesia? 3) Which one is more significant in predicting the morbidity and mortality: acute physiologic status vs chronic health status? METHOD: Preoperative status of the geriatric patients (above 65 years old), who were received operation from June 1994 to March 1996 at Hanil General Hospital, were assessed by APACHE scoring index and ASA classification. Age, sex, type of operation, emergency or elective, method of anesthesia, duration of procedure, APACHE scoring index, ASA classification, perioperative complication, postoperative complication is coded by grading or type. RESULT: Perioperative complication was showed statistically significant with acute physiologic score (APS) and duration of procedure. Postoperative complication was showed statistically significant with APACHE score or ASA class. Total complication was affected by duration of procedure and APS score. There was also correlation between ASA class and total complication. Among 265 cases, 1 case expired during operation and 7 cases expired after operation. Causes of postoperative death were pneumonia, hemorrhagic shock etc. CONCLUSION: In geriatric patients, 1) APACHE scoring index is available for preoperative assessment. 2) APACHE scoring index is meaningful in predicting the risk of anesthesia. 3) Perioperative complication was more correlated with acute physiologic status than chronic health evaluation.

The aims of this study were to evaluate the prognostic predictabilities of the risk classifications (Waterston, Montreal, and Spitz), preoperative treatment of pneumonia and the length of esophageal gap in esophageal atresia. Twenty-five cases of esophageal atresia were reviewed retrospectively. The data was analyzed with Likelihood ratio test for trend and Fisher's exact test. Survival rates were 100.0% in group A and B, and 60.0% in group C according to Waterston classification (p=0.027). By Montreal classification, 95.7% in group I and 50.0% in group II (p=0.086). By Spitz classification, 95.5% in group I and 66.7% in group II (p=0.159). The survival rate was 85.7% in the patients with pneumonia preoperatively treated and 94.4% in the patients without pneumonia. The difference was not significant (p=0.490). Survival rate in the patients with long gap (> or = 3cm) was 50.0% and 100.0% in patients with short gap (< 3cm) with significant difference (p=0.020). The Waterston classification could be modified into two groups because the prognosis of both group A and B were the same. Preoperative pneumonia does not seem to be a risk factor. The length of the esophageal gap showed prognostic value.

BACKGROUND: The clinical and histopathological classification of erythema multiforme(EM) and Stevens-Johnson syndrome (SJS) are difficult due to a lack of clear-cut criteria. In recent studies, some authors suggested that erythema multiforme and Stevens-Johnson syndrome were clinically and histopathologically different disorders. OBJECTIVE: The purpose of this study was to review the clinicopathological characteristics of the EM and SJS and to suggest specific findings for differentiating between the two diseases. METHODS: Fifty four patients with EM and SJS diagnosed in the Department of Dermatology of Dong-San Hcepita1 from January 1987 through to December 1996 were studied retrospectively. RESULTS: The results were summarized as follows. l. In view of causal factors, 54 cases were classified as drug-induced (n=22, 41%), herpes-induced (n=16, 30%), tuberculosis (n= 2, 3%), pneumonia (n=l, 2%), unknown (n=13, 24%). 2. Fifty four cases were clinically classified as SJS (n= 29, 54%), EM minor (n=-15, 2S%) and EM major (n = 10, 18%). 3. Erythema multiforme was found to be more related to herpes (13 of 25 cases) than to drugs (3 of 25 cases), while SJS was more related to drugs (19 of 29 cases) than to herpes (3 of 29 cases). 4. Varying degrees of necroti changes of keratinocytes were found in all the cases. The severity of degree or extent of necrosis was higher in patients with SJS than EM. 5. In demial changes, EM showed differences from SJS by having a denser and deeper lymphocytic infiltrate, and increased amount of extravasated erythrocytes. CONCLUSION: Taken together, although our findings could not provide a defmite clue to determine whether EM and SJS are different distinet entities or not, this study may be useful to differentiate and to understand the pathogenesis of EM and SJS. A prospective large scaled study should be conducted to definitively characterize these entities.
