2.Use of the Circular Grip During Intermittent Catheterization.
Korean Journal of Urology 1997;38(10):1081-1083
A prospective study was carried out on the efficacy of a circular grip which we devised to facilitate a non-sterile intermittent catheterization. The series included 16 females, the mean follow-up time being 7 months. Most patients were suffering from neurogenic bladder disorders and bladder retention after operation. All of them used the circular grip during intermittent catheterization and continued to undergo intermittent catheterization. The technique of the use of the circular grip during intermittent catheterization was usually learnt easily and provided reassurance to the patient and family about intermittent catheterization.

OBJECTIVEPreviously documented indirect adjustment methods could only adjust for the confounding effects from cigarette smoking. The aim of this paper is to introduce a novel method for dealing with the effects of smoking in occupational, epidemiological cohort studies using a 'smoking adjustment factor'.
METHODSA retrospective cohort study among male silicotic workers purely exposed to silica dusts in Hong Kong (1981 - 1999) was used as an example. 'Smoking adjustment factor' in occupationally exposed smoking and nonsmoking sub-cohorts was expressed as 1/(1- PAR% )xRR and 1/1- PAR% respectively. Relative exposure effect and Synergy index were estimated to assess the multiplicative and additive interactions.
RESULTS'Smoking adjustment factor' for non-smoking and smoking silicotic workers was 1/0.33 and 1/1.62 respectively. Lung cancer standardized mortality ratio(SMR) of all cohort members was reduced from 1.61(95% CI: 1.22-2.10) to 1.08(95% CI:0.81-1.41) after indirectly adjusted for smoking effect. Results from our novel indirect method were in line with that from Axelson' s approach. Relative silicosis effect and synergy index were estimated to be 0.63 (95% CI:0.08-0.79) and 0.90 (95 % CI:0.42-1.94) ,suggesting a significant but negative multiplicative interaction between smoking and silicosis on the risk of lung cancer mortality.
CONCLUSIONThe merit of this new method was the ability to adjust for the confounding effect and evaluate the interactive effect with smoking. However, comparability of age distribution between occupationally exposed smoking and nonsmoking sub-cohorts was a prerequisite for the accurate estimations of the smoking indirectly adjusted SMR, relative exposure effect, and/or synergy index.

Population attributable fraction (PAF) is an important public health parameter that is familiar to epidemiologists. The calculation of PAF is frequently based on the relative risk (RR) of a risk factor for a certain disease and the prevalence of exposure to the risk factor in the total population (Pe). We introduce here the method for making a nomogram linking PAF to RR and Pe. The nomogram will be very handy for public health professionals in estimating PAF quickly and accurately when information on RR and Pe is available.

Sparganum infestation of the human body was reported over 120 cases and of the urogenital region was reported over 30 cases in korean literatures since 1924. But, infestation of the penis was reported two cases. We experienced a case of sparganosis in the penile shaft and reporte this case with the review of literature of sparganosis of the genitourinary region.

OBJECTIVESTo assess the association of socioeconomic indicators with various chronic and acute illnesses and the utilization of public health care in a new town in Hong Kong, China.
METHODSIllness experience and socioeconomic and demographic data of 7570 residents from 2022 randomly selected households were collected through telephone interviews. The relationships between socioeconomic indicators and illnesses/choice of health care were explored using stepwise logistic regressions after adjusting for sex and age.
RESULTSSignificant positive associations were noted between low household income and diabetes mellitus, any chronic illnesses among adults and flu among younger subjects; low educational level and accident-related illness among adults; being born in Chinese mainland and flu, any acute illness in adults. For the utilization of public health care, low household income was the most consistent risk factor.
CONCLUSIONThis study did not demonstrate a unidirectional socioeconomic gradient in health but supported the hypothesis that socioeconomic deprivation was associated with the utilization of public health care.

BACKGROUND/AIMS: In 1977, Teele and Smith reported their positive experience using an ultrasonographic in the evaluation of Congenital Hypertrophic Pyloric Stenosis (CHPS). Since that time, ultrasonography has been advocated by some as the diagnostic procedure of choice, although a number of false-negative cases have been encountered at any rate, in 1994, Becker reported that an endoscopy was far more accurate than an ultrasonography, the diagnosis being made in 97% and 81% of the cases. Therefore, we performed a prospective study to evaluate the diagnostic value of an upper gastrointestinal endoscopy in CHPS patients. METHODS: We reviewed the clinical records of 12 pediatric patients experiencing vomiting, who had visited Pusan National University Hospital from January 1993 to March 1997. We performed on upper gastrointestinal endoscopy and abdominal ultrasonography simultaneously in order to evaluate the diagnostic value of an upper gastrointestinal endoscopy in CHPS patients. RESULTS: The male to female ratio was 11: 1. In 7 of 12 patients, 58%, vomited within 4 weeks after birth. Diagnostic sensitivity by abdominal ultrasonography was about 75%, and by upper GI endoscopy, almost 100%. Associated lesions were discovered in 5 cases, 3 esophagitis and 2 gastritis in the upper GI endoscopy. CONCLUSIONS: The upper GI endoscopy was more accurate in the diagnosis of CHPS than the ultrasonography, and was more effective in the diagnosis of associated lesions.

When study on epidemiological causation is carried out,logistic regression has been commonly used to estimate the independent effects of risk factors.as well as to examine possible interactions among individual risk factor by adding one or more product terms to the regression model.In logistic or Cox's regression model.the regression coefficient of the product term estimates the interaction on a muhiplicative scale while statistical significance indicates the departure from multiplicativity.Rothman argues that when biologic interaction iS examined,we need to focus on interaction as departure from additivity rather than departure from multiplicativity.He presents three indices to measure interaction on an additive scale or departure from additivity.using logarithmic models such aS logistic or Cox's regression model.In this paper,we use data from a case-control study of female lung cancer in Hong Kong to calculate the regression coefficients and covariance matrix of logistie model in SPSS.We then introduce an Excel spreadsheet set up by Tomas Andersson to calculate the indices of interaction on an additive scale and the corresponding confidence intervals.The results can be used as reference by epidemiologists to assess the biologic interaction between factors.The proposed method is convenient and the Excel spreadsheet is available online for free.

Purpose:
A CT angiography spot sign (CTA-spot) is a significant predictor of the early expansion of an intracerebral hemorrhage (ICH-Ex). Dynamic-susceptibility-contrast magnetic resonance imaging (DSC-MRI) can track the real-time leaking of contrast agents. It may be able to indicate active bleeding, like a CTA-spot.
Materials and Methods:
From September 2014 to February 2017, we did noncontrast CT, CTA, and DSC-MRI examinations of seven patients with acute ICH. We investigated the time from symptom onset to the first contrast-enhanced imaging.We evaluated the time course of the contrast leak within the ICH at the source image of the DSC-MRI and the volume change of ICH between non-contrast CT and DSCMRI. We compared the number of slices showing CTA-spots and DSC-MRI leaks.
Results:
The CTA-spot and DSC-MRI leak-sign were present in four patients, and two patients among those showed ICH-Ex. The time from the symptom onset to CTA or DSC-MRI was shorter for those with a DSC-MRI leak or CTA-spot than for three patients without either (70-130 minutes vs. 135-270 minutes). The leak-sign began earlier, lasted longer, and spread to more slices in the patients with ICH-Ex than in those without ICH-Ex. The number of slices of the DSC-MRI leak and the number of the CTA-spot were well correlated.
Conclusion
DSC-MRI can demonstrate the leakage of GBCA within hyperacute ICH, showing the good contrast between hematoma and contrast. The DSC-MRI leakage sign could be related to the hematoma expansion in patients with ICH.
