Abstract
OBJECTIVE To determine the prevalence of nocturnal polyuria (NP) in patients with spinal cord injury (SCI) during three different particular phases, and investigate the impact of injury level and injury type on the prevalence of NP. DESIGN A cross-sectional study. SETTING Neurogenic Bladder Study Group from six different rehabilitation centers across the country. PARTICIPANTS 40 patients with SCI. OUTCOME MEASURES Patients were divided into three groups according to mobilization phase; 1st group included patients confined to bed (n = 14), 2nd group included patients sitting on a wheelchair (n = 19) and 3rd group included patients standing with an assistive ambulation device (n = 7). NP was assessed by nocturnal polyuria index (NPi) and nocturnal urine production (NUP) indexes. RESULTS No significant difference was found between the groups (P = 0.312 for NPi and P = 0.763 for NUP) in terms of the presence of NP according to their mobilization phase. The night and 24-hour urine volumes showed no significant difference between the groups (P = 0.907 and P = 0.395 respectively). The NPi and NUP values did not show a significant difference between male and female patients (P = 0.826, P = 0.364 respectively), patients with the injury level of ≥T6 and CONCLUSION In this study, NP was found to be a common problem in patients with SCI regardless of their mobilization phase, injury level and injury type. It was revealed that both NPi and NUP parameters could be used to determine the prevalence of NP in this patient group.

Abstract
The aims of this study were to determine the prevalence and predictors of nocturnal polyuria (NP) in Japanese patients. This multicentral, observational study enrolled patients with the chief complaint of nocturia at 17 Japanese institutions between January 2018 and December 2022. The frequency of daily voiding and volume of urination were evaluated using bladder diaries. NP was diagnosed in patients with an NP index of > 33%. The primary endpoint was NP prevalence in patients with nocturia. The secondary endpoints were the prevalence of NP according to sex and age and the identification of factors predicting NP. This study analyzed 875 eligible patients. NP was present in 590 (67.4%) patients, with prevalence rates of 66.6% and 70.0% in men and women, respectively. Age ≥ 78 years, body mass index (BMI) < 23.0 kg/m2, and patients with ischemic heart or cerebrovascular disease were significant predictors of NP (P < 0.001, P < 0.001, P = 0.014, P = 0.016, respectively). This is the first large multicenter study to investigate the prevalence of NP in Japanese patients with nocturia. NP has a prevalence of 67.4%. Significant predictors of NP include age, BMI, and cardiovascular disease.

Abstract
INTRODUCTION AND HYPOTHESIS Data from a large US population-based, cross-sectional, epidemiological study (the EpiNP Study) were used to assess the symptoms and bother experienced by women with nocturnal polyuria (NP). METHODS Consenting participants recruited from an online panel completed the baseline EpiNP survey online (Lower Urinary Tract Symptoms Tool and urological comorbidities). All reporting ≥2 voids/night and a random sample of 100 respondents, each reporting 0 or 1 void/night were asked to complete a 3-day web-based bladder diary recording time, volume, and urgency rating of each void. NP was calculated by the proportion of urine production that occurred during nocturnal hours using a Nocturnal Polyuria Index (NPI33) threshold of >0.33 or nocturnal urine production of >90 ml/h (NUP90). The frequency of participants reporting LUTS and bother was determined by age and NP: idiopathic NP, NP associated with overactive bladder (NPOAB), NP associated with comorbidities (NPCom), and no NP (did not meet NP criteria). RESULTS A total of 5,290 women completed the baseline survey. Mean age (range) was 54.9 (30-95) years; 1,841 (34.8%) reported ≥2 nocturnal voids. The prevalence of LUTS increased across the lifespan; however, bother associated with each LUTS decreased with increasing age. The percentage of women rating bother by nocturia episodes ≥2 "> somewhat" ranged from 40.3% to 68.3%, with bother ratings highest in the NPOAB and No NP groups. CONCLUSIONS NP is prevalent in women with considerable bother and is often associated with other urinary symptoms. Multifactorial causes and potential treatments of NP should be considered, particularly at a later age.

Abstract
PURPOSE To evaluate the pathophysiology of nocturia based on the frequency volume chart, and determine the risk factors for nocturia occurring ≥2 times per night. MATERIALS AND METHODS In this retrospective study, we reviewed 311 patients with complaints of nocturia from January 2017 to February 2019 at our institution. Nocturnal polyuria (NP) and global polyuria (GP) were defined as NP index >0.35 regardless of age and 24 h urine volume >2.5 L/day, respectively. Decreased bladder capacity (dBC) was when the maximal voided volume was <325 mL. Decreased nocturnal bladder capacity (dNBC) was defined as nocturnal bladder capacity index >0. RESULTS In total, 273 patients were included in the primary analyses. Of 802 days from 273 frequency volume charts, the median number of nocturia was 1 episode per day. Further, NP (odds ratios [OR] 7.01), GP (OR 4.25), dBC (OR 3.00), dNBC (OR 10.12), and age (OR 1.04) had the association with nocturia ≥2 times per night. There was a significant stepwise increase in NP, dNBC, dBC, and GP with the number of nocturia episodes. As patient age increased, the likelihood of NP (P < 0.001) and dBC (P < 0.001) being the cause for nocturia tended to increase, but that of dNBC (P = 0.022) and nocturia without cause (P = 0.007) tended to decrease. Moreover, dBC was more likely to cause nocturia in female patients than in male patients (P < 0.001). CONCLUSION NP, dBC, dNBC, and GP are important factors involved in the pathophysiology of nocturia occurring ≥2 times per night.

Abstract
Central diabetes insipidus (CDI) is a complex disorder in which large volumes of dilute urine are excreted due to arginine-vasopressin deficiency, and it is caused by a variety of conditions (genetic, congenital, inflammatory, neoplastic, traumatic) that arise mainly from the hypothalamus. The differential diagnosis between diseases presenting with polyuria and polydipsia is challenging and requires a detailed medical history, physical examination, biochemical approach, imaging studies and, in some cases, histological confirmation. Magnetic resonance imaging is the gold standard method for evaluating the sellar-suprasellar region in CDI. Pituitary stalk size at presentation is variable and can change over time, depending on the underlying condition, and other brain areas or other organs - in specific diseases - may become involved during follow up. An early diagnosis and treatment are preferable in order to avoid central nervous system damage and the risk of dissemination of germ cell tumor, or progression of Langerhans Cell Histiocytosis, and in order to start treatment of additional pituitary defects without further delay. This review focuses on current diagnostic work-up and on the role of neuroimaging in the differential diagnosis of CDI in children and adolescents. It provides an update on the best approach for diagnosis - including novel biochemical markers such as copeptin - treatment and follow up of children and adolescents with CDI; it also describes the best approach to challenging situations such as post-surgical patients, adipsic patients, patients undergoing chemotherapy and/or in critical care.

Abstract
Most cases of acquired central diabetes insipidus are caused by destruction of the neurohypophysis by: 1) anatomic lesions that destroy the vasopressin neurons by pressure or infiltration, 2) damage to the vasopressin neurons by surgery or head trauma, and 3) autoimmune destruction of the vasopressin neurons. Because the vasopressin neurons are located in the hypothalamus, lesions confined to the sella turcica generally do not cause diabetes insipidus because the posterior pituitary is simply the site of the axon terminals that secrete vasopressin into the bloodstream. In addition, the capacity of the neurohypophysis to synthesize vasopressin is greatly in excess of the body's needs, and destruction of 80-90% of the hypothalamic vasopressin neurons is required to produce diabetes insipidus. As a result, even large lesions in the sellar and suprasellar area generally are not associated with impaired water homeostasis until they are surgically resected. Regardless of the etiology of central diabetes insipidus, deficient or absent vasopressin secretion causes impaired urine concentration with resultant polyuria. In most cases, secondary polydipsia is able to maintain water homeostasis at the expense of frequent thirst and drinking. However, destruction of the osmoreceptors in the anterior hypothalamus that regulate vasopressin neuronal activity causes a loss of thirst as well as vasopressin section, leading to severe chronic dehydration and hyperosmolality. Vasopressin deficiency also leads to down-regulation of the synthesis of aquaporin-2 water channels in the kidney collecting duct principal cells, causing a secondary nephrogenic diabetes insipidus. As a result, several days of vasopressin administration are required to achieve maximal urine concentration in patients with CDI. Consequently, the presentation of patients with central diabetes insipidus can vary greatly, depending on the size and location of the lesion, the magnitude of trauma to the neurohypophysis, the degree of destruction of the vasopressin neurons, and the presence of other hormonal deficits from damage to the anterior pituitary.

Abstract
OBJECTIVE Polydipsia and polyuria are common reasons for referral to the Pediatric Endocrine clinic. In the absence of hyperglycemia, diabetes insipidus (DI) should be considered. The objectives of the study were to determine the prevalence of central DI (CDI) in a group of children presenting for evaluation of polydipsia and polyuria, and to determine if predictive features were present in patients in whom the diagnosis of DI was made. METHODS The study was a retrospective chart review of children presenting to the endocrine clinic with complaints of polydipsia and polyuria over a 5-year period. RESULTS The charts of 41 patients (mean age 4.9 ± 3.7 years, 28 males) were reviewed. CDI was diagnosed in 8 (20%) children based on abnormal water deprivation test (WDT) results. All but one patient had abnormal magnetic resonance imaging (MRI) findings, the most common being pituitary stalk thickening. Children with DI were older (7.86 ± 4.40 vs. 4.18 ± 3.20 years, P = .01) and had a higher propensity for cold beverages intake and unusual water-seeking behaviors compared to those without DI. Baseline WDT also revealed higher serum sodium (Na) and osmolality. CONCLUSION The incidence of CDI in children presenting with polydipsia and polyuria is low. Factors associated with higher likelihood of pathology include older age, propensity for cold beverage intake, and higher baseline serum Na and osmolality on a WDT. ABBREVIATIONS BMI = body mass index CDI = central diabetes insipidus DI = diabetes insipidus Na = sodium WDT = water deprivation test.

Abstract
OBJECTIVE To explore the pathway to diagnosis of type 1 diabetes (T1D) in children. DESIGN Questionnaire completed by parents. PARTICIPANTS Parents of children aged 1 month to 16 years diagnosed with T1D within the previous 3 months. SETTING Children and parents from 11 hospitals within the East of England. RESULTS 88/164 (54%) invited families returned the questionnaire. Children had mean±SD age of 9.41±4.5 years. 35 (39.8%) presented with diabetic ketoacidosis at diagnosis. The most common symptoms were polydipsia (97.7%), polyuria (83.9%), tiredness (75.9%), nocturia (73.6%) and weight loss (64.4%) and all children presented with at least one of those symptoms. The time from symptom onset to diagnosis ranged from 2 to 315 days (median 25 days). Most of this was the appraisal interval from symptom onset until perceiving the need to seek medical advice. Access to healthcare was good but one in five children presenting to primary care were not diagnosed at first encounter, most commonly due to waiting for fasting blood tests or alternative diagnoses. Children diagnosed at first consultation had a shorter duration of symptoms (p=0.022) and children whose parents suspected the diagnosis were 1.3 times more likely (relative risk (RR) 1.3, 95% CI 1.02 to 1.67) to be diagnosed at first consultation. CONCLUSIONS Children present with the known symptoms of T1D but there is considerable scope to improve the diagnostic pathway. Future interventions targeted at parents need to address the tendency of parents to find alternative explanations for symptoms and the perceived barriers to access, in addition to symptom awareness.

Abstract
AIM To investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of empagliflozin in patients with type 2 diabetes following oral administration of 10, 25 or 100 mg doses once daily over 28 days. METHODS A total of 78 patients were assigned to empagliflozin 10 mg (n = 16), 25 mg (n = 16) or 100 mg (n = 30) or placebo (n = 16) for 28 days. Assessments included adverse events (AEs) and pharmacokinetic and pharmacodynamic endpoints. RESULTS Empagliflozin exposure increased dose-proportionally over the dose range 10-100 mg and showed linear pharmacokinetics with respect to time. Urinary glucose excretion (UGE) increased from baseline to day 1 by 74, 90 and 81 g with empagliflozin 10, 25 and 100 mg, respectively. The increases in UGE were maintained over 28 days with multiple dosing. Virtually no change in UGE was observed in the placebo group. Significant reductions from baseline in mean daily plasma glucose and fasting plasma glucose were observed with empagliflozin compared with placebo. The incidence of AEs was similar in the empagliflozin and placebo groups (50.0, 56.3 and 66.7% with empagliflozin rising doses and 62.5% with placebo). The most frequently reported AEs were pollakiuria (10.3%), nasopharyngitis (9.0%), constipation (9.0%) and headache (7.7%). CONCLUSIONS Oral administration of empagliflozin at doses of 10, 25 or 100 mg once daily over 28 days resulted in significant increases in UGE and reductions in blood glucose compared with placebo, and were well tolerated in patients with type 2 diabetes.

Abstract
INTRODUCTION AND HYPOTHESIS The aim of the present study was in a case-control design to evaluate the association between nocturia and obstructive sleep apnea, in men and women who had nocturia ≥ 2 per night (nocturics) compared to those without nocturia (controls). METHODS Participants were randomly selected among respondents in a population study of 4000 elderly individuals. Nocturia was assessed using the validated Nocturia, Nocturnal Enuresis, and Sleep-interruption Questionnaire (NNES-Q). Nocturia (≥ 2 voids/night) or control (< 1 void/night) status was assessed by a 3-day frequency volume chart (FVC). Furthermore, all participants completed an overnight ambulatory polygraphic recording to identify obstructive sleep apnea (OSA). RESULTS Of 1111 eligible individuals, a total of 75 nocturics and 75 controls (13.5%) were included. Overall, the prevalence and severity of OSA among nocturics and controls was not significantly different. In a sub-analysis we found that 22 nocturics with OSA (69%) had nocturnal polyuria. This led to a significantly increased risk of having OSA (OR 2.8, 95% CI: 1.1-7.3, p < 0.05) when having nocturnal polyuria compared to other pathophysiological causes of nocturia (polyuria, low bladder capacity, a combination of nocturnal polyuria/low bladder capacity, and neither nocturnal polyuria/low bladder capacity). CONCLUSIONS Nocturia twice or more was not significantly associated with OSA. However, nocturics with nocturnal polyuria had a significantly higher risk of having OSA than nocturics with other pathophysiologies.

Abstract
The aim of the study was to elucidate a relationship between the development of hypernatremia and the frequency of poor outcomes in children with severe brain injury (SBI). The retrospective study enrolled 77 children (54 boys and 23 girls) aged 1 month to 18 years, who had SBI in the period of January 2008 to September 2009, and were divided into 3 groups after treatment termination. The admission injury severity criterion was Glasgow coma scale (8 scores or less) rating. Group A comprised 51 children with SBI without hypernatremia; Group B included 14 children with SBI and hypernatremia. Group C consisted of 12 children with SBI, hypernatremia, and polyuremia. The latter group was appraised as a group with evolving central diabetes insipidus. A total of 26 (33.8%) patients had hypernatremia. Poor outcomes (Glasgow outcome scores of 1-3) at 30 days were noted in only Groups B and C: comparison of outcomes in Groups B and C showed the higher incidence of poor outcomes in 10 (84%) Group C patients (with hypernatremia and polyuria) and 4 (28%) children in Group B. Comparison of Groups B and C children indicated that the hazard ratio was 0.3. Therefore, the risk of poor outcomes is much higher in the development of central diabetes insipidous in the presence of hypernatremia.

Abstract
This retrospective survey examines the etiology of nephrocalcinosis (NC) in 40 patients (26 boys), over an 8-year period. The median age at onset of symptoms and presentation was 36 months and 72 months, respectively. Clinical features included marked failure to thrive (82.5%), polyuria (60%) and bony deformities (52.5%). The etiology of NC included distal renal tubular acidosis (RTA) in 50% patients and idiopathic hypercalciuria and hyperoxaluria in 7.5% each. Other causes were Bartter syndrome, primary hypomagnesemia with hypercalciuria, severe hypothyroidism and vitamin D excess. No cause for NC was found in 12.5% patients. Specific therapy, where possible, ameliorated the biochemical aberrations, although the extent of NC remained unchanged. At a median (range) follow up of 35 (14-240) months, glomerular filtration rate (GFR) had declined from 82.0 (42-114) ml/min per 1.73 m2 body surface area to 70.8 (21.3-126.5) ml/min per 1.73 m2 body surface area (P = 0.001). Our findings confirm that, even with limited diagnostic facilities, protocol-based evaluation permits determination of the etiology of NC in most patients.

Abstract
This study was undertaken to evaluate the relation between hip fractures and nocturnal micturition habits in elderly men and women. A questionnaire survey was undertaken among 10,216 elderly subjects. The mean (+/-S.D.) ages of the men and women were 73.0+/-6.0 and 72.6+/-6.7 years, respectively. A hip fracture during the past five years had occurred in 97 (3.9%) of the men and 175 (4.6%) of the women and the occurrence increased with increasing age in both sexes. In both men and women nocturnal micturition increased with age. Among men, passing of subjectively large amounts of urine at night was reported to occur never or very seldom in 63.3% and rather seldom, rather often, and very often in 21.9%, 12.7%, and 2.1%, respectively. The corresponding frequencies in women were 65.1%, 17.2%, 13.7%, and 3.9%, respectively. Multiple logistic regression analysis with sex, nocturia, and nocturnal voided volumes as independent variables and occurrence of hip fracture during the last five years as the dependent variable showed that the risk of having had a hip fracture was increased by nocturia three or more episodes versus two or fewer; odds ratio (OR) 1.8, confidence interval (CI) 1.1-3.0, and by large nocturnal urine volumes, very often versus very seldom or never; (OR 3.5; CI 1.8-7.3). One can conclude that in these elderly subjects the risk of hip fractures during a five-year period was increased independently by increased nocturnal micturition and increased nocturnal urine output.

Abstract
Nocturia is a common symptom associated with benign prostatic hyperplasia which can persist even after effective treatment of BPH. Other causes may be responsible. We investigated a group of patients who were treated for BPH and continue to have nocturia. Our study has found a high prevalence (85.4%) of nocturnal polyuria in this group of patients. It has important clinical implication since the condition can be effectively treated with oral desmopressin. Empirical treatment without a routine frequency volume chart may be appropriate due to its high prevalence.

Abstract
OBJECTIVE This study was undertaken to determine the prevalence of nocturnal polyuria in women complaining of nocturia and overactive bladder (OAB) symptoms and to identify clinical and health characteristics associated with nocturnal polyuria. STUDY DESIGN Women presenting to a urogynecology clinic with complaints of nocturia and OAB symptoms were asked to participate. They completed a health characteristic summary, 3-day voiding diary, Nordic sleep questionnaire, urinary distress inventory (UDI), and a nocturia distress visual log (NDVL). The 24-hour urine production, nighttime urine volume, and maximum bladder capacity were calculated from the bladder diary. Nocturnal polyuria was defined as production of greater than 33% of the 24-hour urine volume during an 8-hour sleep period. A histogram was performed to analyze at what age the prevalence of nocturnal polyuria increased. Women were then divided by presence or absence of nocturnal polyuria and compared by the health and clinical characteristics. RESULTS Fifty-five women met the qualifications and participated in the study. Average age of the cohort was 65.8 +/- 13.5 years. The risk of nocturnal polyuria increased with age 65 years or older (prevalence for age 65-74 = 0.86 [0.62-1.00]) and with white race. On the basis of the mean population values for UDI, NDVL, sleepiness scores, and insomnia scores, all women were bothered by their nocturia. Median number of nighttime voids, 24-hour urine production, maximum bladder capacity, nocturnal index, UDI, NDVL, sleepiness scores, and insomnia scores did not differ, based on presence or absence of nocturnal polyuria. CONCLUSION Among women complaining of nocturia and overactive bladder symptoms, age 65 years or older and white race appear to be risk factors for nocturnal polyuria.

Abstract
The aim of this study was to assess components of variation in nocturia and to determine any putative geomagnetic influence. A 54-year old man with benign prostatic hyperplasia had recorded for about 4 years the number of times he awoke each night to urinate. The data have been reanalyzed for chronomics, the mapping of time structures (chronomes), involving the computation of least squares spectra of the urinary record and of environmental variables recorded during the same 4-year span. In addition to the previously reported monthly variation, other periodicities have been documented, including two separate components with periods of one week and of a near-week. The precise 7-day period may be a mainly exogenous resonance with external influences such as a weekly social schedule, whereas the near-week may be a partial resonance with natural changes in geomagnetics, reflecting in part changes in other non-photic natural environmental factors.

Abstract
STUDY OBJECTIVE The purpose of this study was to examine the relationship between nocturia and obstructive sleep apnea (OSA) in community dwelling older men and women. DESIGN A repeated measures design was employed over a 24-hour period. SETTING The study was conducted in a clinical research center. PARTICIPANTS Thirty community-dwelling elders (mean age=65.5, SD=8.4 years) with symptoms of nocturia and sleep disordered breathing, volunteered to participate. Both men (n = 13) and women (n = 17) and minority subjects (African-Americans, n = 19; Caucasian, n = 11) were included in the study. INTERVENTIONS NA. MEASUREMENTS Blood specimens were collected every 4 hours, except for an 8-hour collection period overnight. Urine specimens were collected ad libitum and at the end of each data collection interval. Urine and blood specimens were analyzed for ANP and AVP content. Polysomnography was conducted using a full 18-channel montage. Apnea was defined as a decrease in airflow of > or = 90% for a minimum of 10 seconds. Hypopnea was defined as > or = 30% decrease in airflow and desaturations required a > or = 3% decrease in oxygen saturation for a minimum of 10 seconds. The apnea hypopnea index (AHI) was calculated as the sum of apneas and hypopneas divided by hours of sleep. RESULTS Twenty of the thirty subjects were found to have clinically diagnosable OSA (AHI > or = 5). AVP excretion was not correlated with changes in AHI levels. Conversely, total urine output, plasma ANP and urine ANP excretion were significantly higher among subjects with higher AHI levels (> 15). CONCLUSION In subjects with elevated AHI (> 15), nighttime urine production and ANP excretion are elevated.

Abstract
OBJECTIVE To determine the age prevalence of nocturnal polyuria among older women in the community, and to investigate the relationship between nocturnal polyuria and nocturia. PATIENTS AND METHODS In all, 1183 women aged > or = 50 years, who were registered with a family doctor practice and who had taken part in a prevalence study, were sent brief questionnaires and a frequency/volume chart (FVC) to complete. RESULTS There were 227 FVCs with adequate data and 264 completed questionnaires available for analysis. The prevalence of nocturnal polyuria increased disproportionately with age. There was no clear relationship between nocturia or nocturnal polyuria and daytime frequency, nor was there a clear relationship between diuretic use and nocturnal polyuria. CONCLUSION Nocturnal polyuria is common among women in the community and not obviously related to daytime frequency. Night-time symptoms are common in women as well as men, and are troublesome to them.

Abstract
During a recent epidemic of Plasmodium falciparum malaria in Hlabisa district, KwaZulu Natal, polyuria was recognized in a subset of adults presenting to hospital with severe disease. In January to May 2000, following consent, cases of severe malaria provided blood spots for HIV testing, clinical data, and blood and urine samples for investigation of the polyuria. Four hundred and eleven adults with malaria were admitted, of whom 175 had severe malaria and 37 had polyuria (21% of severe cases). In those with polyuria the mean 24-h urine output was 3018 ml or 2.85 ml/kg/h. Ten of 15 (66%) patients investigated had urine and plasma osmolalities consistent with diabetes insipidus. There was no significant association between polyuria and sex, age, HIV status or features of severe malaria. Whether the polyuria in these non-immune adults is a localized problem unrelated to malaria, or a hitherto unrecognized complication of severe malaria is not clear. Physicians are alerted to this observation, and the need for more clinical and pathophysiological studies.

Abstract
Although nocturnal voiding is frequently attributed to urologic disorders, nocturia and enuresis are also important symptoms of sleep-disordered breathing. However, polyuria can be elicited by obstructive sleep apnea as well as bedrest, microgravity and other experimental conditions where the blood volume is shifted centrally to the upper body. The nocturnal polyuria of sleep apnea is an evoked response to conditions of negative intrathoracic pressure due to inspiratory effort posed against a closed airway. The mechanism for this natriuretic response is the release of atrial natriuretic peptide due to cardiac distension caused by the negative pressure environment. This cardiac hormone increases sodium and water excretion and also inhibits other hormone systems that regulate fluid volume, vasopressin and the rennin-angiotensin-aldosterone complex. Treatment of sleep apnea and airway compromise has been shown to reverse nocturnal polyuria and thereby reduce or eliminate nocturia and enuresis. Thus, careful evaluation of nocturia and enuresis for evidence of nocturnal polyuria can increase the diagnostic certainty of referring primary care providers and sleep specialists. In addition, the resolution of these bothersome symptoms after treatment can contribute to patient satisfaction as well as reinforce treatment compliance.

Abstract
The goals of this study were to describe the pattern of voiding disorders in children in our community, to describe clinical criteria for making the specific diagnoses, and to comment on management. The medical records of 226 children referred because of voiding dysfunction or urinary tract infections (UTI) were evaluated. Children with normal voiding patterns when uninfected, with monosymptomatic nocturnal enuresis, and with known neurologic or anatomic abnormalities were excluded. Detrusor instability, an abnormal voiding pattern characterized by urgency with or without frequency, was the diagnosis in 175 of the 226 children. Children with detrusor instability who used various posturing maneuvers to avoid urinary incontinence had a significantly higher incidence of UTIs than those who did not attempt to obstruct urine outflow. Detrusor instability appeared to be secondary to constipation in 19 of the children. The other diagnoses were extraordinary daytime urinary frequency, infrequent voiding, monosymptomatic daytime wetting, transient voiding dysfunction, giggle incontinence, dysfunctional voiding, and unexplained dysuria. It is concluded that children with detrusor instability who use posturing maneuvers to avoid incontinence are at high risk for recurrent UTIs. Constipation is 1 cause of detrusor instability. Dysfunctional voiding, the form of voiding dysfunction most likely to result in renal damage, was present in only 2 of 226 children seen for voiding disorders.

Abstract
AIM The aim of study was analysis of type 1 diabetes mellitus symptoms at admission to hospital. MATERIAL AND METHODS Thirty-seven patients (21 boys and 16 girls) aged from 1.87 to 19.75 years with admitting diagnosis of diabetes mellitus in the year 2000 (the greatest count of patients) were analyzed. In statistical analysis the t-Student test was used. RESULTS The most frequent symptoms was dry sensation in mouth 95% of patients, polydypsia 84%, polyuria 65%, lose on weight 49%, nocturia - 27% children. Nine children were admitted to hospital in serious ketoacidosis. Twenty-eight children were admitted to hospital in good condition. There were not essential abnormalities in the blood. Observation period in poor general condition group was shortest for children living in the country - on the average 9 days versus patient from cities - 18 days. There was not difference in good general condition group. HbA1c, pH, HCO3 values were statistically significant. In 3 cases diagnosis of diabetes mellitus was preceded by an eliminating others diseases. In 2 children hyperglycemia was established by chance. CONCLUSION 1) Ketoacidosis symptoms and serious state was observed in 1/4 patient admitted to hospital. 2) It is necessary to take diabetes mellitus into consideration more often in differentiation in pediatric practice. 3) Short observation period of severe ketoacidosis symptoms in-patient from country origin and dismiss preliminary diagnosis may indicate insufficient healthy education - especially in the field of diabetes mellitus. 4) Less than half of patients report to family doctors.

Abstract
OBJECTIVES To describe the normal values for nocturnal urine production and its determinants, as well as the relation between nocturnal urine production and voiding frequency. METHODS Data were collected from 1688 men aged 50 to 78 years without bladder or prostate cancer, radical prostatectomy, neurogenic bladder dysfunction, or negative advice from their general practitioner. Measurements included self-administered questionnaires, a 3-day frequency-volume chart, transrectal ultrasonography of the prostate, uroflowmetry, and postvoid residual urine volume measurement. The mean nocturnal urine production was computed from the frequency-volume charts. Linear regression analyses were performed to determine associated factors for nocturnal urine production. Areas under the receiver operating characteristic curves were used to describe the discriminative value of nocturnal urine production on nocturnal voiding frequency. A cutoff value for "increased" nocturnal urine production was defined using logistic regression analysis. RESULTS The nocturnal urine production was 60.6 mL/hr for the total study population; it increased with age and was significantly higher in men with 24-hour polyuria. Nocturnal urine production was on average higher in men with increased nocturnal voiding frequency, but had only a reasonable discriminative value on nocturnal voiding frequency (areas under receiver operating characteristic curve of 0.71 and 0.76). Nocturnal urine production exceeding 90 mL/hr is suggested as abnormal. CONCLUSIONS On average, nocturnal voiding frequency is indicative of nocturnal urine production. However, nocturnal urine production is only a modest discriminator for increased nocturnal voiding frequency. Therefore, the use of nocturnal urine production as an explanatory variable for nocturnal voiding frequency in daily practice is of little value.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence of polydipsia-hyponatremia among patients with schizophrenia in an Asian mental hospital. METHOD Seven hundred and twenty-eight inpatients with schizophrenia were assessed for polydipsia-hyponatremia using case notes reviews, specific gravity of urine, normalised diurnal weight gain, and serum sodium levels. RESULTS One hundred and three (13.8%) patients had polydipsia, 30 (4.1%) had polydipsia-hyponatremia and 14 (1.9%) had a history of water intoxication. Eight of the 30 patients were receiving carbamazepine, three were on tricyclic antidepressants and two had diabetes mellitus and were on sulfonylureas. CONCLUSION The prevalence of water intoxication among polydipsic patients was low compared to Western studies. This could be due to different methods of assessing polyuria, or ethnic differences and/or the prohibition of smoking in our patients. Certain medications might have also contributed to hyponatremia.

Abstract
The value of a water deprivation test incorporating urinary arginine vasopressin (AVP) measurement was investigated in 13 patients with polydipsia and/or polyuria (complete central diabetes insipidus [CCDI] in four; incomplete central diabetes insipidus [ICDI] in five; secondary nephrogenic diabetes insipidus [NDI] in three; compulsive water drinking [CWD] in one) and a group of 25 control subjects (C). Urine samples were collected after water deprivation during sleep and the urinary osmolalities and AVP concentrations were measured. Analysis of the results of 104 urine samples from the 25 control subjects demonstrated a close correlation between urinary osmolality and AVP (r = 0.89, P < 0.001). After water deprivation during sleep, the respective mean maximal urinary osmolalities and AVP concentrations were: 127.4 +/- 34.4 mOsm/kg and 1.1 +/- 0.5 pg/mL in the patients with CCDI (14 samples, four children); 410.3 +/- 101.8 and 6.1 +/- 3.5 in those with ICDI (16 samples, five children); 348.7 +/- 71.2 and 100 +/- 45.1 in those with NDI (nine samples, three children); 541.5 +/- 143.5 and 43.6 +/- 33.2 in the patient with CWD (two samples, one child) and 898.8 +/- 186.3 and 97.4 +/- 50.4 in group C (54 samples, 18 children). Furthermore, the urinary AVP level relative to the osmolality in each patient varied depending on the AVP secretion status and renal concentrating ability. Each patient, except the one with CWD, could be discriminated from the normal subjects using this test. It seems that this test is easy to perform and useful for diagnosis and follow-up of patients with partial/complete posterior pituitary function defects and those with renal concentration impairment.

Abstract
Insulin-dependent diabetes mellitus is common in Tunisia. Eighty-six pediatric cases managed at the diabetes clinic of a department of pediatrics in Tunis from 1979 through 1989 were studied. Relevant clinical and biological findings were abstracted from case-records. Admissions of patients with diabetes mellitus accounted for approximately 0.44% of admissions to the pediatric ward during the study period. Mean age of patients was 7 years. Sex ratio was 0.89. Polyuria with polydipsia and ketoacidosis were the two most common presenting manifestations. Mean blood glucose level at diagnosis was 22.44 mmol/l. Rate of consanguinity was 48%. HLA typing studies demonstrated a high prevalence of DR3 and DR4 alleles and especially of simultaneous expression of both these alleles. Several factors are incriminated in the development of childhood insulin-dependent diabetes mellitus.
