Purpose : Diabetes mellitus (DM) is known as one of the common causes of secondary enuresis in children. However, enuresis in diabetic children is overlooked only as a symptom of polyuria due to hyperglycemia. We evaluated the prevalence of nocturnal enuresis in children with diabetes mellitus in this paper. Methods : Among children with diabetes in three hospitals in Daegu area, 117 agreed to 'Tele research by means of a questionnaire'. Results : Diabetic patients were divided into two groups: Nocturnal enuresis and nonnocturnal enuresis group. thirty-two of 117 (27.0%) patients were in enuresis group, with more daytime urination than non-nocturnal enuresis group ($4.2{\pm}1.6/3.6{\pm}1.2$ times, P=0.016). HbA1c at diagnosis was $12.0{\pm}2.3%/12.0{\pm}2.5%$, and at follow-up $9.3{\pm}2.3%/8.3{\pm}2.3%$ (P =0.042). Insulin was administered at $1.1{\pm}0.5/1.1{\pm}0.4$ units/kg/day. Ten children of enuresis (31.2%) group were monosymptomatic (MNE) and 22 (68.8%) children were non-monosymptomatic enuresis (non-MNE). Fourteen (43.8%) of enuresis group had persistent symptoms, with 5 MNE and 9 non-MNE each. HbA1c at diagnosis was $11.1{\pm}2.5$, $12.4{\pm}2.1$, higher in non-MNE (P=0.144). Average arousal during sleep was step $3.3{\pm}1.2$, $2.5{\pm}1.0$, higher in improved enuresis group (P=0.059). Conclusion : Nocturnal enuresis among DM patients is underestimated. However, considering psychological and social effects of enuresis in children, extensive and long-term studies are needed in the future to clarify relationship between prevalence and DM control.

야뇨증은 소아뿐만 아니라 부모들에게 매우 애를 먹이는 현상이며, 때로는 정신적, 정서적 장애 또는 행동장애를 유발할 수도 있다. 적절한 치료를 하기 위하여서는 세심한 병력, 신체검사와 필요에 따라서 적절한 실험실 검사 및 방사선검사으로 단인증상성 야뇨증인지를 제대로 구별하여야 한다. 실제 임상에서 야뇨증의 치료는 그렇게 용이하지만은 않아 우선 어린이와 부모들이 야뇨증을 제대로 이해할 수 있도록 사전 교육을 통하여 적극적인 치료 의지를 갖도록 하는 것이 중요하다. 여러 가지 행동요법 및 야뇨경보기, 적절한 약물요법을 환자의 상황에 맞도록 적절한 치료 방법을 모색하여 보다 치료 효과가 높고 재발이 적도록 노력하여야 한다.

Purpose: Recently, the conception and cognition that enuresis was resolved spontaneously, have changed. We reviewed the attitudes of the primary care physicians who make diagnose and treat nocturnal enuresis. Methods: From January 2006 to February 2007, a total of 293 primary care physicians in Daegu city participated in this survey. Questionnaires included questions about physicians' opinions on the appropriated age for diagnosis of enuresis, the likely causes of enuresis, etc. Physicians are grouped in two according to whether enuresis is major field of their subspecialty; the pediatrician & urologist group and the other physician group. Results: 59.2% of pediatricians and urologists thought that enuresis is defined as the nightly involuntary release of urine by children of the age of 5 to 6, while 49.6% of other physicians did. For the causes of enuresis, most of clinicians checked "yes" to the question that "Under-developed bladder and nerve" and "Emotional problems". In the patient's behavioral reactions related to enuresis, "Lack of concentration in home and school" and "Frequent urination" were most responded. Attendance to the education program of enuresis in last five years and willing to participate in education program was statistically different among pediatricians-urologists and other physicians. Regarding the treatment of enuresis, most physicians used imiprarnin widely, but pediatricians and urologists preferred desmopressin. Alarm was the last one in treatment modality. Conclusion: This study revealed that pediatricians and urologists are attending more to the educational places and knowing much about the recent information on enuresis when compared to other primary care physicians, regarding the diagnostic age and treatment modality of enuresis. The education of enuresis for primary physicians is more needed.

This study was designed to evaluate the emotional and behavioral problems of nocturnal enuresis children(n=72) in general population. And this was compared with normal control children(n=72). The behavioral problems were assessed using a modified child behavior checklist(CBCL) parent form. The results indicated that enuretic children were rated significantly more anxious, fearful, depressed, inattentive, hyperactive, delinquent on the modified CBCL rating when compared to the age-, grade- and sex-matched normal control children. Finally, it was an impressive evidence that there exist many emotional and behavioral problems in children with nocturnal enuresis.

Purpose: The Pathogenesis of primary noctllrnal enuresis(PNE) is still controversial. Genetic factor and maturational delay of micturition reflex including arousal disorder, lack of nocturnal Arginine Vasopressin(AVP) release and functional bladder capacity have been suggested. We analyzed the risk factors of PNE. Methods: Fifty five children with PNE (20 enuretics diagnosed at school physical examination of the first grade students at Mok-Dong Elementary School and 35 enuretics (Age 6-7 year) diagnosed at Ewha Womans University Mok Dong Hospital) and 221 control students without PNE at school physical examination were included. Genetic, stress and developmental factors, arousability, water intake, urine volume, maximun voiding volume and daytime voiding dysfunction were compared. Results: 1) There was no significant difference between PNE and control group in sex ratio, birth order, percentage of working mothers, parental and child personality, age to start walking, school record and duration of sleep. 2) Family history in the PNE group was significantly higher than control group ($20.0\%\;vs\;2.7\%$)(P<0.05). 3) The difficulty in arousal in the PNE group was significantly more common than the control group ($70.9\%\;vs\;54.3\%$)(P<0.05). 4) Nocturnal water intake in the PNE group was significantly greater than the control group ($330{\pm}158.2\;mL\;vs\;235{\pm}129.5\;mL$). Nocturnal urine volume in the PNE group was significantly greater than the control group ( $390{\pm}61.5\;mL\;vs\;140{\pm}43.2\;mL$)(P<0.05). Daily water intake and daily urine volume did not significantly differ between the two groups. 5) Maximum urine volume per void in the PNE group was significantly lower than the control group ($107{\pm}35.9\;mL\;vs\;236{\pm}41.3\;mL$). Daytime voiding dysfunction in the PNE group was significantly more common than the control group ($80.0\%\;vs\;57.9\%$). The voiding frequency in the PNE group was significantly greater than the control group ($7.0{\pm}3.6\;vs\;5.4{\pm}1.6$)(P<0.05). Conclusion: In addition to genetic factors and maturational delay of micturition reflex (difficulty in arousal, nocturnal polyuria and decreased functional bladder capacity) nocturnal polydypsia was found to be the important risk factors fur PNE. So nocturnal fluid restriction should be encouraged as the first-line management of PNE.

Purpose : It is important to take a precise history of patients to diagnose enuresis. However, this is difficult to perform in the outpatient department, because the consultation time is limited. So by taking the medical histories with questionnaires, we classified the enuresis patients into monosymptomatic and non-monosymptomatic groups and compared the clinical characteristics between the two groups in order to determine whether this would aid in the diagnosis and treatment of enuresis. Methods : Thirty-four enuresis patients seen in the Department of Pediatrics at Yeungnam University Hospital from 2004 January to 2005 July were enrolled in this study. Two to three weeks before starting medical treatment, questionnaires about the patients' urination habits and past medical history were taken from the Parents with consents. Results : There were 21 patients in the monosymptomatic group and 13 patients in the non-monosymptomatic group. There was no difference in the delivery mode, birth weight, birth order, sleep habit, constipation, and treatment results between the two groups. Urinary infection was more frequently observed in the non-monosymptomatic group. There was a higher incidence of daytime incontinence and a past medical history of allergy in the non-monosymptomatic group. Oriental medicine was the most common treatment of enuresis before visiting the hospital, but the treatment effect was minimal. Conclusion : Comparison between the monosymptomatic and non-monosymptomatic group with the questionnaires was helpful for detailed diagnosis and treatment of enuresis. A more effective education for enuresis patients is needed, since before visiting the hospital many of them wasted their efforts with ineffective oriental medicine treatment.

This study was conducted to investigate the effects of dietary activated coconut charcoal (ACC) on Performance, e99 quality and Plasma cholesterol level of Plasma in laying hens. One hundred forty four, 47-wk-old, ISA Brown commercial layers were used in a 28-d feeding trial after a 7-d adjustment Period. Four dietary treatments were 0, 0.5, 1.0 and 1.5e% levees of ACC supplemented to a corn-soybean meal basal diet. Egg Production was significantly increased as the levels of ACC increased. However, egg weight was significantly decreased by the addition of ACC in diets. Egg shell breaking strength tended to decrease as the level of ACC increased, however, no significance was found in this respect. As the levels of ACC increased, egg shell thickness decreased significantly. Although not significant, yolk color tended to increase by the addition of ACC. Egg folk index were significantly increased by the addition of ACC In diet. No significant difference was found among four treatments in total cholesterol, HDL cholesterol, and LDL+VLDL cholesterol concentrations in plasma. In conclusion, dietary supplementation of ACC to layer diets could be used to increase egg Production, and yolk index.
