In the present study we conducted a regression analysis of age at menarche against Maximum Peak Velocity (MPV) of height in non-athlete Korean girls which was derived with the wavelet interpolation method, and composed linear to quartic regression polynomials to obtain the best regression polynomial. We then applied the age at menarche and age at MPV of height of athletes to the best polynomial regression evaluation, and investigated the validity of a delayed menarche evaluation that we constructed. Moreover, the relation between delayed menarche and menstrual status was examined by investigating delayed menarche and menstrual pain in individuals for the first time. The subjects were 124 second year female students at a physical education high school in the suburbs of Pusan, South Korea. A questionnaire survey of these girls was conducted, from which their date of birth, age at menarche, and athletic activities in elementary, junior high, and high school were obtained. In addition, health check records were examined retrospectively, and longitudinal growth data for height were obtained from the 1st year of elementary school (7 years old) until the second year of high school (17 years old). Next, the same survey as above was also done for second year students at a general high school in the same area, as a control group. Three hundred forty-five non-athletes for whom all data were available were selected. As the results, the third order polynomial was found to be most suitable for the regression polynomial. When it was applied to individual female Korean athletes with respect to the regression evaluation, positive scores were obtained for many athletes and an overall delay in menarche was seen. Delayed menarche was not seen, however, in archery athletes. A strong delay in menarche was thus found in Korean athletes. And it was shown that 80% had moderate or greater menstrual pain and a close relation with menstrual abnormalities, the effectiveness of the delayed menarche evaluation was further validated.

The aquatic quality of the Naktong river after two of three months in June, 1991 with phenol spillage from a electrical factory in Kumi was investigated. The samples were collected at six sites of the Naktong river basin and Kachang and Kongsan lakes. Phenol was not detected from all water samples. Turbidity was very much increased to the down stream in the Naktong river. The BOD and COD values exceeded the 2nd grade(3 mg/l) of the Korean standard quality of Environmental Water Act at the all sampling sites of the Naktong river. Especially, the value of COD at Kaejin (12.5 mg/l) was poorly classified as to the 5th grade of water class for the environmental quality standards. Organophosphorous pesticides such as parathion, malathion, fenitrothion and diazinon were investigated but not detected. Diazinon was only detected at the Ilson bridge(1.42 ppb), Okkye stream(6.95 ppb), Waekwan bridge(0.32 ppb), Gangjung reservior(0.13 ppb), Kaejin(0.05 ppb). Of the carbamates such as carbanyl, isoprocarb and cabofuran, the carbofuran was detected all sites except tap water, and Kachang and Kongsan lakes. The content of heavy metals such ans Cd, Pb, Zn, Fe, Mn, Hg were not exceeding for drinking water standards at the all sampling region, but only mecury was detected from Okkye stream(0.018ppb) and Kaejin(0.09ppb). In the regions of Kachang and Kongsan lakes, the content of heavy metals were lower than that of reservoir of Naktong river.

Thirty consecutive patient seen in a pediatric out patient and emergency department, in whom the diagnosis of intussusception was considered, had an ultrasound examination of the abdomen before the barium enema. The peak age was 5~12 month (range 4~34 month). Intussusception was detected by ultrasonography in all 25 cases proved by barium enema (sensitivity 100%). Normal findings on ultrasonography correlated with a negative barium enema results in 5 of 5 cases (negative predictive value=100%). No intussusception was missed by ultrasonography. To determine which patient would most benefit from ultrasonography, we divided patients into either a high risk group (100% intussusception) or a low risk group (37.5% intussusception) on the basis of clinical symptoms. We conclude that ultrasonography can be used as a rapid sensitive screening procedure in the diagnosis or exclusion of childhood intussusception. Probability of surgical reduction was associated with size of of total thickness and external rim thickness.

Much has been learned of the pathogenesis and pathophysiology of the toxic shock syndrome (TSS) since the initial description in 1978 by Dr. James K, Todd. The clinical illness is defined by the criteria listed in the case definition formulated for epidemiologic studies. With the advent of widespread recognition of TSS, there have been numerous published reports describing the clinical and laboratory findings, primarily in menstruating females. And there have been also reported about six cases in Korea. Moreover, TSS is uncommon in the prepubertal age group and no case report in infant in Korea. We experienced two cases of TSS in infants aged 11/2 yrs and 9 months associated with respiratory infection-pneumonia, pyopneumothorax and localized skin abscess that were confused with Kawasaki disease (KD). The diagnosis was made on the basis of clinical features and laboratory findings, and the cases met the Centers of Disease Control case definition of TSS. And thus we report these cases and review related literatures.

Background: The coronavirus disease (COVID-19) can manifest in a range of symptoms, including both asymptomatic systems which appear nearly non-existent to the patient, all the way to the development of acute respiratory distress syndrome (ARDS). Specifically, COVID-19–associated pneumonia develops into ARDS due to the rapid progression of hypoxia, and although arterial blood gas analysis can assist in halting this deterioration, the current environment provided by the COVID-19 pandemic, which has led to an overall lack of medical resources or equipment, has made it difficult to administer such tests in a widespread manner. As a result, this study was conducted in order to determine whether the levels of oxygen saturation (SpO2) and the fraction of inhaled oxygen (FiO2) (SF ratio) can also serve as predictors of ARDS and the patient’s risk of mortality. Methods: This was a retrospective cohort study conducted from February 2020 to Mary 2020, with the study’s subjects consisting of COVID-19 pneumonia patients who had reached a state of deterioration that required the use of oxygen therapy. Of the 100 COVID-19 pneumonia cases, we compared 59 pneumonia patients who required oxygen therapy, divided into ARDS and non-ARDS pneumonia patients who required oxygen, and then investigated the different factors which affected their mortality. Results: At the time of admission, the ratios of SpO2, FiO2, and SF for the ARDS group differed significantly from those of the non-ARDS pneumonia support group who required oxygen (p<0.001). With respect to the predicting of the occurrence of ARDS, the SF ratio on admission and the SF ratio at exacerbation had an area under the curve which measured to be around 85.7% and 88.8% (p<0.001). Multivariate Cox regression analysis identified that the SF ratio at exacerbation (hazard ratio [HR], 0.916; 95% confidence interval [CI], 0.846–0.991; p=0.029) and National Early Warning Score (NEWS) (HR, 1.277; 95% CI, 1.010–1.615; p=0.041) were significant predictors of mortality. Conclusion The SF ratio on admission and the SF ratio at exacerbation were strong predictors of the occurrence of ARDS, and the SF ratio at exacerbation and NEWS held a significant effect on mortality.

OBJECTIVE: Anxiolytics and antidepressants are commonly used to treat depressive disorders in pregnant women. Specific and clear evidence is required when managing pregnant patients with such medications to ensure safety. However, information provided by approval label information is insufficient and often different among many countries. By analyzing label information of approval label and other references, this study aims to show the limitations and suggest appropriate directions for retrieving safety information. METHODS: We selected five anxiolytics and eleven antidepressants, which belongs to Korea drug classification codes 117 (psychotropic agents). We chose four countries, Korea, the United States of America (USA), the United Kingdom, Japan and collected safety information for pregnant women in label information. We evaluated the safety information based on recommendation level and evidence level. Then, kappa value and overall agreement were calculated using SAS 9.3. to assess data homogeneity. We further searched Reprotox and a textbook about contraindicated drugs in label information. RESULTS: Recommendation level and evidence level was different in each country. The number of commonly contraindicated drug in label information of four countries was none, and contraindicated drugs in labels were different respectively. Kappa value of evidence level between label information of Korea and Japan, the USA and Japan was 0.61, 0.43 respectively, corresponding to 'substantial agreement' and 'moderate agreement'. The overall agreement was 75%, 62.5% respectively. The information of label was different from that of other references, Reprotox and a textbook in terms of the clinical evidences and recommendation levels. CONCLUSION: Safety information of anxiolytics and antidepressants in label information needs to be updated on a regular basis both for health professionals and patients. With the implication of the inconsistent guidance for the safety information in pregnant women, reliable safety information in pregnant women would be needed.

A few cases of laparoscopic surgery for urachal remnant in children has been reported in English literature. With recent developments in minimal invasive surgery, laparoscopic approach for urachal remnant in adulthood is recommended by some laparoscopic surgeons because of its technical feasibility and safety as well as cosmesis. Recently we experienced a case of complicated urachal remnant in a 14-month-old girl, who was managed by laparoscopic approach. At presentation, she complained of high fever and lower urinary tract symptoms. After 6 weeks of antibiotics therapy, laparoscopic surgery was performed transperitoneally via 3 ports. Our experience suggests that laparoscopic excision of urachal remnant can be performed easily and safely in children.

BACKGROUND: All types of membranoproliferative glomerulonephritis (MPGN) are progressive diseases with poor prognoses. Recently, a newly proposed classification of these diseases separated them into immune complex- and complement- mediated diseases. We investigated the frequency of C3 glomerulonephritis among previously diagnosed MPGN patients. METHODS: We conducted a retrospective study of patients diagnosed with MPGN at three tertiary care institutions between 2001 and 2010. We investigated the incidence of complement-mediated disease among patients diagnosed with MPGN. Progressive renal dysfunction was defined as a 50% reduction in the glomerular filtration rate or the need for renal replacement therapy. RESULTS: Among the 3,294 renal biopsy patients, 77 (2.3%) were diagnosed with MPGN; 31 cases were excluded, of which seven were diagnosed with systemic lupus nephritis, and the others were not followed for a minimum of 12 months after biopsy. Based on the new classification, complement-mediated MPGN was diagnosed in two patients (4.3%); only one patient developed progressive renal dysfunction. Among the immune complex-mediated MPGN patients, 17 patients developed progressive renal dysfunction. Serum albumin and creatinine levels at the time of MPGN diagnosis were risk factors of renal deterioration, after adjusting for low C3 levels and nephrotic syndrome. CONCLUSION: Complement-mediated glomerulonephritis was present in 4.3% of patients previously diagnosed with MPGN.
