    To evaluate the outcomes of conservatively managed staghorn calculi, specifically looking at morbidity and mortality, incidence of infections and progressive changes in renal function. A total of 22 patients with unilateral or bilateral staghorn calculi, who were treated conservatively, were included in the study. Patients were reviewed yearly with symptom assessment, urine culture and measurement of estimated glomerular filtration rate. The presentations to the urology department of staghorn calculi were incidental (41%), haematuria (36%), abdominal discomfort (5%) and recurrent urinary tract infections (UTIs; 18%). The reasons for conservative management in the cohort were comorbidities (59%), patient choice (36%) or poor access/anatomy (5%). In the whole cohort the rate of recurrent UTIs was 50%, the progressive renal failure rate was 14%, the disease-specific mortality rate was 9%, the dialysis dependence rate was 9% and the rate of hospital attendances attributable to stone-related morbidity was 27%. Comparison of outcome measures between the unilateral and bilateral staghorn stones showed statistically significant differences in disease-specific mortality (0 vs 40%) and morbidity (12 vs 80%) in favour of the unilateral group. Although there was a lower incidence of UTIs (41 vs 80%), renal deterioration (6 vs 40%) and dialysis requirement (6 vs 20%) in the unilateral group, these findings were not statistically significant. From the results, we conclude that conservative management of staghorn calculi is not as unsafe as previously thought. Careful patient selection to include unilateral asymptomatic stones with minimal infection, and thorough counselling with regard to the risks, could make conservative management a suitable option for specific patient groups. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    Full Text Available INTRODUCTION: Uretric stones can be treated with multiple modalities including medical therapy, uretroscopy, shockwave lithotripsy (SWS, percutaneous nephrolithotomy, open/laparoscopic stone removal, and/or combinations of these modalities. The aim is to study the effectivene ss of medical management of uretric stones and to compare the effectiveness of Tamsulosin and Tamsulosin with steroid . MATERIALS & METHODS: 120 Patients who came with acute uretric colic were categorized into III categories of less than 5mm, 5mm to 7mm and more than 7mm based on NCCT. They were consecutively allotted to one of the three groups, the group I patients received Anti - Biotics with NSAIDs group II received Tamsulosin in addition Anti - Biotics and NSAIDs and III rd group received Anti - Biotics, Tamsu losin, NSAIDs in addition Deflazacart 30mg for a period of 10 days. The results were evaluated at the end of 10 days medical treatment. RESULTS : 90 out of 120 patients were re - evaluated at the end of 10 days. The calculi of 7mm should be removed as the chances of passage is <20%. The medical treatment with Tamsulosin or Tamsulosin with Deflazacart does not offer significant benefit.

    The aim of this study was to determine the caries experience and oral health related quality of life of 12-year-olds on the Caribbean island of Montserrat. In addition, any difference in the dental caries experience was explored by gender and socio-economic status. A total of forty-six 12-year-olds were living on the island at the time of the study and 32 (69%) participated in the survey. Caries experience was recorded using the decayed, missing and filled teeth (DMFT) index by a trained and calibrated examiner according to the British Association for the Study of Community Dentistry (BASCD) criteria. The Care Index was used to describe the level of dental care. The Child Perception Questionnaire was used to investigate the impact of oral health conditions on oral health-related quality of life. Statistical software Dental Survey Plus and SPSS were used to analyse data. The findings of this study showed that the 12-year-olds had a mean DMFT of 1.91 and 59% had active untreated caries with an overall Care Index of 16%. While the perception of oral symptoms was low, over a third of children reported a functional impact as a result of their oral condition. It is concluded that there is a need for improved delivery of restorative care coupled with oral health promotion and dental health education.

    Congenital megaprepuce is a specific form of buried penis. Children affected by this malformation usually suffer from a subjective difficulty in voiding which is the main indication for early surgical correction. The aim of this study was to report a single center's 12-year experience in the treatment of megaprepuce in children, describing the surgical procedure we used to treat it and the results. We retrospectively reviewed the charts of all children who underwent congenital megaprepuce repair between January 1999 and August 2011 in our institution. Fifty-two children were operated during the study period. Our single surgical technique, not an original one, consists of fixing the penile shaft at the base of the penis, and widely reducing the inner prepuce. Four children (8%) underwent revision surgery but according to our criteria a very good result was observed in only 23 patients, and a less good but still acceptable result in 25 patients. Our 12-year experience in the surgical treatment of congenital megaprepuce demonstrated satisfying results from a safe and simple surgical technique, but to achieve the optimum result remains difficult.

    To assess the efficacy of ursodeoxycholic acid (UDCA) in patients with intrahepatic cholestasis of pregnancy (ICP) and in the outcome of pregnancy. Retrospective analysis of our 12-year experience treating ICP patients with UDCA. Thirty-two patients with pruritus starting before week 34 of pregnancy and with increased serum bile salts (BS) and alanine aminotransferase (ALT) received UDCA (15 mg/kg/day) for at least 3 weeks before delivery. They were compared with 16 historical controls who did not receive UDCA. All patients were followed up until delivery and in puerperium. Newborns were followed up during 3 months. UDCA treatment attenuated pruritus (P or = 37 weeks) occurred in 65.7% of UDCA-treated patients compared with only 12.5% in controls (P cholestasis, and facilitated deliveries at term in ICP patients, with a higher birthweight compared with historical controls. The drug was well tolerated and no adverse effects were detected in their infants.

Materials and Methods: Twenty-three pregnant women, aged between 19 and 28 years presented to the obstetric and urology departments with renal colic (17 cases, 73.9% and fever and renal pain (6 cases, 26.1%; suggesting ureteric stones. The diagnosis was established by ultrasonography (abdominal and transvaginal. Outpatient follow-up consisted of clinical assessment and abdominal ultrasonography. Follow-up by X-ray of the kidneys, ureter, and bladder (KUB, or intravenous urography (IVU was done in the postpartum period. Results: Double J (DJ stent was inserted in six women (26% with persistent fever followed by extracorporeal shock wave lithotripsy (ESWL one month post-partum. Ureteroscopic procedure and pneumatic lithotripsy were performed for 17 women (distal ureteric stone in 10, middle ureter in 5, and upper ureteric stone in 2. Stone-free rate was 100%. No urologic, anesthetic, or obstetric complications were encountered. Conclusions: Ureteroscopy, pneumatic lithotripsy, and DJ insertion could be a definitive and safe option for the treatment of obstructive ureteric stones during pregnancy.

    The Large Electron Positron Collider (LEP) has ended its last physics run in November 2000, and it is at present being dismantled to liberate the tunnel for the Large Hadron Collider (LHC) project to be completed by end of 2005. The cryogenic systems for the superconducting solenoid and focusing quadrupoles for the two LEP experiments, ALEPH and DELPHI, each supplying a cooling power of 800 W/4.5 K entropy equivalent, have accumulated more then 100'000 hours of running time. The paper summarises the 12 years cryogenic experience in the various operating modes: cool-down, steady state, recovery after energy fast dump, utilities failures and warm-up of the superconducting magnets. The detailed operation statistics is presented and compared to the other CERN cryogenic systems. Emphasis is given to the technical analysis of the fault conditions and of their consequences on the helium refrigeration production time in view of the future operation of the LHC cryogenics.

    Hirschsprung disease (HD) is a chronic condition associated with long-term morbidity. We assessed the short and long-term functional outcomes of operated patients in a single institution over a 12-year period. We conducted a retrospective review of all children operated for HD between 2002 and 2014. Postoperative functional outcomes were assessed using the Rintala Bowel Function Score (BFS, 0-20, 20=best score). We assessed hospital admissions, complications including Hirschsprung associated enterocolitis (HAEC) and the need for further surgical procedures. 72 (52 male) patients were studied, of whom, 6 (8%) had a positive family history, 5 (7%) had Trisomy 21 and 5 (7%) had total colonic HD. The median age at diagnosis was 6.5days (2 days-6.7 years) and median follow-up was 6years (1-12years). All patients except two underwent a Duhamel pull-through procedure. The median age at surgery was 4months (6days-90months). 37 (51%) procedures were performed single-stage and 7 (10%) were laparoscopically assisted. Our early complication rate was 15%; 11 (15%) patients were treated for HAEC and 43 (60%) did not require any further surgery. 12 (17%) underwent injection of botulinum toxin, 7 (10%) needed residual spur division and 4 (5%) required an unplanned, post pull-through enterostomy for obstructive defecation symptoms and HAEC. Two (3%) patients underwent an Antegrade Colonic Enema (ACE) stoma. The median BFS was 17 (5-20). There were two deaths both out of hospital. Long-term functional outcomes following Duhamel Pull-Through surgery are satisfactory although 40% of patients needed some form of further surgical intervention. The management of anal sphincter achalasia has improved with the use of botulinum toxin and we advocate aggressive and early management of this condition for symptoms of obstructive defecation and HAEC.

    The exact prevalence of oral lesions in childhood is not well known. We sought to define the prevalence of oral mucosal lesions in a large group of children. A retrospective cross-sectional study was performed using clinical charts from January 1997 to December 2007. Data collected included age, gender, and pathologic diagnosis. In total, 10,128 children (0-12 years old) were enrolled. Clinical diagnostic criteria proposed by the World Health Organization were followed. The frequency of children presenting oral mucosal lesions was 28.9%, and no differences related to gender were observed. The most frequent lesions recorded were oral candidiasis (28.4%), geographic tongue and other tongue lesions (18.5%), traumatic lesions (17.8%), recurrent aphthous ulcerations (14.8%), herpes simplex virus type 1 infections (9.3%), and erythema multiforme (0.9%). Children suffering from chronic diseases had a higher frequency of oral lesions compared with healthy children (chi-square: P oral disorders are associated with underlying medical conditions.

    Full Text Available Objective. Duodenal atresia (DA routinely has been corrected by laparotomy and duodenoduodenostomy with excellent long-term results. We revisited the patients with DA treated in the last 12 years (2004–2016 comparing the open and the minimally invasive surgical (MIS approach. Methods. We divided our cohort of patients into two groups. Group 1 included 10 patients with CDO (2004–09 treated with open procedure: 5, DA; 3, duodenal web; 2, extrinsic obstruction. Three presented with Down’s syndrome while 3 presented with concomitant malformations. Group 2 included 8 patients (2009–16: 1, web; 5, DA; 2, extrinsic obstruction. Seven were treated by MIS; 1 was treated by Endoscopy. Three presented with Down’s syndrome; 3 presented with concomitant malformations. Results. Average operating time was 120 minutes in Group 1 and 190 minutes in Group 2. In MIS Group the visualization was excellent. We recorded no intraoperative complications, conversions, or anastomotic leakage. Feedings started on 3–7 postoperative days. Follow-up showed no evidence of stricture or obstruction. In Group 1 feedings started within 10–22 days and we have 1 postoperative obstruction. Conclusions. Laparoscopic repair of DA is one of the most challenging procedures among pediatric laparoscopic procedures. These patients had a shorter length of hospitalization and more rapid advancement to full feeding compared to patients undergoing the open approach. Laparoscopic repair of DA could be the preferred technique, safe, and efficacious, in the hands of experienced surgeons.

    Full Text Available Introduction: Congenital diaphragmatic hernia (CDH is a severe malformation, displaying relevant mortality and morbidity rates in newborns.Aim: To characterize clinically and demographically all neonatal cases of CDH admitted to a level III Neonatal Intensive Care Unit during a 12-year period and to evaluate the predictive value of baseline characteristics on mortality and morbidity at discharge.Methods: Maternal/infant clinical and electronic records were ret-rospectively reviewed. All neonates with posterolateral CDH admitted between January 2003 and December 2014 were included.Results: Fifty-three newborns were included. Overall mortality during hospitalization was 22/53 (41.5%. Clinical characteristics associated with mortality were the presence of intrathoracic liver (p = 0.005, intrathoracic stomach (p = 0.015, elevated arterial pCO2 or lower pH values at admission (respectively, p = 0.001 and p < 0.001, pre-ductal oxygen saturation < 85% at admission (p = 0.012 and surgical repair with prosthetic patch (p = 0.041. Morbidity at discharge was reported in 7 (22.6% survivors. Stomach herniation and sepsis were associated with higher morbidity (respectively, p = 0.012 and p = 0.029. In a logistic regression, patch repair was the only variable with predictive value for death during hospitalization, with an odds ratio (OR of 15 (95% CI 0.98-228.9, and intrathoracic stomach was a predictor of morbidity at discharge (OR = 15.7, 95% CI 1.4-174.2.Conclusion: Structural characteristics, namely defect size and presence of intrathoracic stomach, remain the primary determinants of neonatal prognosis in CDH. Although post-natal approaches have progressively proven their value in increasing survival and improving management of high-risk cases, future researches should continue focusing on the definition of foetal anatomical markers of severity and prenatal treatment of CDH.

    With advances in endourology, open stone surgery for staghorn calculi has markedly diminished. Anatrophic Nephrolithotomy (AN) is performed for complex staghorn stones which cannot be cleared by a reasonable number of Percutaneous Nephrolithotomy (PNL) attempts. To assess the indications and outcomes of AN in the modern era. Between April 2008 and July 2015, AN was done in 14 renal units in 13 patients. In this retrospective study, demography, stone characteristics, operative details, clearance and long term outcomes were assessed. AN was performed for complex staghorn calculi involving pelvis and all calyces in 10 patients, infundibular stenosis in two patients and failed PNL in one patient. Mean (SD) in situ cold ischemia time was 47.64 (5.27) minutes. Retroperitoneal drain and double J stent were placed in all 13 patients. Median (IQR) estimated blood loss was 130 (75) ml. There was no perioperative mortality. Surgical site infection was seen in 2 patients and urosepsis in 2 patients. Drain was removed at a mean (SD) of 9.11 (6.15) days. Mean (SD) postoperative length of hospitalization was 15.44 (7.14) days. Stent removal was done in all patients between 2-8 weeks. Median (IQR) clearance was 95 (7.5%). There was no renal failure or new calculi during the follow up period {median (IQR): 1(3) years}. AN is effective in management of large staghorn calculi failed minimally invasive approaches and achieves 80%-100% clearance without much need for secondary interventions. Renal function is preserved and with emergence of laparoscopy and robotics, postoperative stay is minimized with expedited recovery and comparable results with open surgery.

    Full Text Available Objective: To report the experience of treating ureteral calculi byureteroscopy at the Faculdade de Medicina do ABC – SP, with anemphasis on the efficacy and safety of the method. Methods: Aretrospective analysis of 100 ureteroscopies performed fromJanuary 2001 to August 2003 in 98 patients with ureteral calculi.Results: A 91% success rate was observed with a single procedureusing this technique. Intracorporeal lithotripsy was necessary in61% of cases before removing the stone; in the remaining cases, itwas extracted with no disintegration. Endoscopic approach wasimpossible in only one patient who required conversion toconventional open surgery. The double-J stent was inserted in73.7% of procedures. Complications were observed in 8% of cases.Conclusion: The present study demonstrated results comparablewith those reported in large series in the literature. The high successrates, low morbidity, rapid convalescence and lack of estheticconsequences corroborate the role of ureteroscopy as an attractivealternative for treating ureteral calculi.

    2005-08-01

    Background: Even after surgery and radiotherapy, malignant gliomas still have a poor prognosis. The authors report on their experience with IORT in 71 patients. Patients and methods: From May 1992 to February 2004, 71 patients with malignant gliomas were treated with IORT. 26 patients suffered from grade III gliomas, 45 patients from glioblastomas (GBM). IORT was carried out using a standard electron tube and 9- to 18-MeV electrons. 52/71 patients who were primarily treated received 20 Gy IORT + 60 Gy postoperative radiotherapy, 19/71 patients with recurrences only received IORT (20-25 Gy). Results: The complication rates were 1.4% for wound infections and 5.6% for hemorrhage. Median disease-specific survival amounted to 14.9 months (gliomass III) and 14.2 months (GBM). The 2-year survival rates amounted to 26.9% (gliomas III) and 6.8% (GBM; p=0.0296). Total versus subtotal resection had no significant influence on survival (p=0.0741), nor had age, sex, tumor site, performance status, size, primary versus recurrence, and radiation dose. A comparison to a conventionally treated patient group did not show a significant survival improvement. 3 months after treatment, initial symptoms had improved in 59% (hemiparesis), 50% (aphasia), 50% (hemianopsia), and 60% (convulsions). Conclusion: IORT has been shown to be feasible; perioperative complication rates were not increased. Survival was generally not improved compared to a historical control group. Recurrences achieved the same survival as primary tumors, and GBM also had a slightly increased survival, thus being possible indications for IORT. (orig.)

    It is important to evaluate concurrently the benefit for dental caries and the risk for dental fluorosis from early exposure to fluoride among children. To evaluate associations of different levels of exposure to fluoride in early childhood with dental caries and dental fluorosis experience in school children. A Child Dental Health Survey (CDHS) was conducted among school children in the Australian state of New South Wales (NSW) in 2007. Trained and calibrated examination teams conducted oral epidemiologic examinations to assess caries experience as decayed, missing or filled tooth surfaces of the primary and permanent dentitions (dmfs/DMFS) and fluorosis using the Thylstrup & Fejerskov (TF) index on the maxillary central incisors only. A parental questionnaire collected information on residential histories and tap water usage to enable calculation of percentage of 3-year lifetime exposure to fluoride in water. Use of dietary fluoride supplements was also collected. Dental caries and fluorosis experience were compared among groups by levels of exposure to fluoride from water and fluoride supplements in bivariate and multivariable analysis, controlling for socioeconomic factors. Exposure to different fluoride sources varied in the group of 2611 children aged 8-12 years. Lower household income was significantly associated in both bivariate and multivariable analyses with the greater prevalence and severity of primary tooth caries among 8-10-year-old children and permanent tooth caries among 8-12 year old. Exposure to fluoride in water during the first 3 years of life was associated with both caries and fluorosis experience observed at age 8-12 years. Having higher percentage of 3-year lifetime exposure to fluoride in water was associated with higher prevalence of mostly mild fluorosis, but significantly lower prevalence and severity of caries in the primary and permanent dentitions. There were significant associations of dental caries and fluorosis experience with

    Although the specialty of cardiothoracic surgery has been practiced in Nigeria for many years, open heart surgery (OHS) has only in the last decade become relatively more frequent, mainly through visiting foreign cardiac surgical teams. At this early phase of development it is faced with multiple challenges, especially financing and local skilled manpower for which solutions have to be identified in order to ensure sustainability and future growth. This study is aimed at highlighting these obstacles to growth of cardiothoracic surgery based on our own institutional experience at Lagos State University Teaching Hospital (LASUTH) and the current status of OHS activity in other cardiothoracic centers in Nigeria. Prospectively acquired data from our center from March 2004 to December 2015 was reviewed. A telephone survey was also conducted with all other institutions in Nigeria performing cardiac surgery. During the study period 1,520 patients underwent various procedures with a mean age of 37±22.4 years and 813 (53.5%) were males. There were 450 major procedures (29.6%), 889 minor procedures (58.5%) and 181 endoscopic procedures (11.9%). The top ten clinical diagnoses were empyema thoracis (17.5%), malignant pleural effusion (14.7%), chest trauma (12%), hemodialysis access (6.1%), bradyarrhythmia (5.3%), aerodigestive foreign bodies (4.1%), vascular injury (3.9%), pericardial disease (3.8%), lung cancer (3.6%) and congenital heart disease (3.4%). The range of procedures was chest tube insertion (41.6%), endoscopy (11.9%), lung procedures (7%), arterio-venous fistula (6.1%), pacemaker implantation (5.3%), vascular repair (4.4%), OHS (3.4%), esophageal procedures (2.6%), chest wall surgery (2%), video assisted thoracic surgery (2%), closed heart surgery (1.6%), diaphragmatic procedures (1.6%) and thymectomy (1%). Survey of 15 centers in Nigeria with cardiac surgery activity showed a total of 496 OHS cases between 1974 and 2016, with 330 cases (66.5%) done between 2012

    Withdrawal from dialysis is a common mode of death in patients undergoing dialysis. Anecdotally most patients have a physician-directed dialysis withdrawal (DW) following an acute medical precipitant, rather than a patient-narrated planned withdrawal as part of a collaborative end-of-life care plan. We report a 12-year retrospective experience of patients undergoing dialysis who died following DW, and suggest clinical parameters which can be used to identify patients who are able to direct their end-of-life care process. Retrospective 12-year review of inhouse electronic and paper records. 867 patients undergoing dialysis died during the study period. 93 patients died from DW. 9 (10%) patients electively withdrew in the absence of an acute medical precipitant and 84(90%) withdrew from dialysis for medical reasons. Patients who chose to withdraw were 10 years younger at dialysis initiation and withdrawal, had greater reported sessional difficulties/intolerances (pdialysis (pdialysis withdrawn for medical reasons (pdialysis tolerance, cognitive decline, rehabilitation post an acute medical precipitant and, place of residence are parameters which differentiate between patients who choose to withdraw from dialysis and those who have dialysis withdrawn for medical reasons. These parameters can be used to identify terminal patients on dialysis who are able to be directive in their end-of-life advanced care planning. Published by the BMJ Publishing Group Limited.

    PurposeRetrospective evaluation of 12-year experience with endovascular management of acute mesenteric ischemia (AMI) due to embolic occlusion of the superior mesenteric artery (SMA).Materials and methodsFrom 2003 to 2014, we analysed the in-hospital mortality of 37 patients with acute mesenteric embolism who underwent primary endovascular therapy with subsequent on-demand laparotomy. Transcatheter embolus aspiration was used in all 37 patients (19 women, 18 men, median age 76 years) with embolic occlusion of the SMA. Adjunctive local thrombolysis (n = 2) and stenting (n = 2) were also utilised.ResultsWe achieved complete recanalization of the SMA stem in 91.9 %. One patient was successfully treated by surgical embolectomy due to a failed endovascular approach. Subsequent exploratory laparotomy was performed in 73.0 % (n = 27), and necrotic bowel resection in 40.5 %. The total in-hospital mortality was 27.0 %.ConclusionPrimary endovascular therapy for acute embolic SMA occlusion with on-demand laparotomy is a recommended algorithm used in our centre to treat SMA occlusion. This combined approach for the treatment of AMI is associated with in-hospital mortality rate of 27.0 %.

    The aim was to assess possible relationship between oral hygiene, salivary cariogenic microflora, buffer capacity, secretion rate and caries experience in 6 year olds and 12 year olds in Riga, and to evaluate these variables in relation to caries risk. 50 children aged 6 and 71 children aged 12 were examined clinically and by bitewing X-ray for caries diagnosis. Green-Vermillion oral hygiene index, stimulated salivary flow rate and buffer capacity were estimated (CRT-buffer; Ivoclar, Vivadent, Liechtenstein). Salivary mutans streptococci (MS) and lactobacilli (LB) (CRT-bacteria; Vivadent) were determined only for children with dmft/DMFT>4: 60% at age of 6, 54,9% at age of 12. All data were statistically analyzed using frequency tables, Pearson chi2test and ANOVA analysis. Mean DMFT was 0.12 in 6 year olds, and 4.6 in 12 year olds. Mean Green-Vermillion index was 0.75 in 6 year olds and 0.99 in 12 year olds. Caries experience and Green-Vermillion index were associated only in 6 year olds (p=0.024). Salivary MS was associated with Green-Vermillion index only in 12 year olds (p=0.086). Salivary MS and caries experience were associated only in 12 year olds (p=0.010). Salivary LB was associated with stimulated saliva's secretion rate only in 12 year olds (p=0.027). Salivary cariogenic microflora level and buffer capacity were associated in 6 year olds (p for MS=0.010; p for LB=0.052). Same association was observed only between salivary MS and buffer capacity in 12 year olds (p=0.081). Stimulated saliva's secretion rate and buffer capacity were associated only in 12 year olds (p=0.004). Information of caries risk factors should be used to work effectively on caries reduction in 6 year olds and 12 year olds in Riga.

    Treatment of malignant pleural mesothelioma (MPM) remains a clinical challenge. The aim of this study was to identify selection factors for allocation of MPM patients to multimodal therapy based on survival data from 12 years of experience. Eligible patients had MPM of all histological subtypes with clinical stage T1-3 N0-2 M0. Induction chemotherapy consisted of cisplatin/gemcitabine (cis/gem) or cisplatin/pemetrexed (cis/pem), followed by extrapleural pneumonectomy (EPP). Multivariate analysis was performed to assess independent prognosticators for overall survival (OS). A Multimodality Prognostic Score was developed based on clinical variables available before surgery. From May 1999 to August 2011, 186 MPM patients were intended to be treated with induction chemotherapy followed by EPP. Hematologic toxicity was significantly less frequent after cis/pem compared to cis/gem, but there was no difference in response or OS between the regimens. One hundred and twenty-eight patients underwent EPP with a 30-day mortality of 4.7%. Fifty-two percent of the patients received adjuvant radiotherapy. The median OS of patients undergoing EPP was significantly longer with 22 months (95% confidence interval: 20-24) when compared to 11 months (9-12) for patients treated without EPP. A prognostic score was defined considering tumor volume, histology, C-reactive protein level, and response to chemotherapy that identified patient groups not benefitting from multimodality treatment which was confirmed in an independent cohort. Patients receiving induction chemotherapy followed by EPP for MPM of all histological subtypes and irrespective of nodal status showed a median survival of 22 months. A prognostic score is proposed to help patient allocation for surgery after validation in an independent cohort.

    There are instances where small or large pockets are filled with diced cartilage in the nose, without use of wrapping materials. For this purpose, 1-cc commercial syringes were used. The obtained results were partial and incomplete. For better and improved results, the author designed new syringes, with two different sizes, which compress the diced cartilage for injection. The author presents his experience accrued over the past 12 years with 2366 primary, 749 secondary, 67 cleft lip and nose, and a total of 3182 rhinoplasties, using his new syringe design, which compresses diced cartilage and injects the diced cartilages as a conglutinate mass, simulating carved costal cartilage, but a malleable one. In 3125 patients, the take of cartilage graft was complete (98.2 percent) and a smooth surface was obtained, giving them a natural appearance. In 21 patients (0.65 percent), there was partial resorption of cartilage. Correction was performed with touch-up surgery by reinjection of a small amount of diced cartilage. In 36 patients (1.13 percent), there was overcorrection that, 1 year later, was treated by simple rasping. Compared with diced cartilage wrapped with Surgicel or fascia, the amount of injected cartilage graft is predictable because it consists purely of cartilage. The injected diced cartilage, because it is compressed and becomes a conglutinated mass, resembles a wood chip and simulates carved cartilage. It is superior to carved cartilage in that it is moldable, time saving, and gives a good result with no late show or warping. The injection takes only a few minutes.

    The main salivary glands are the submaxillary, sublingual and parotid glands. Infectious and tumoral conditions are prominent in the parotid gland whilst calculi are in submaxillary and sublingual glands. METHODS. Medical record review of 18 cases with a diagnosis of salivary calculi over a 13 year period. Data collected consisted in, clinical presentation, ultrasound (US), sialography (SG) and computarized tomography (CT), and treatment. 13 male and 5 female. Mean age was 7.2 years. All of them presented with pain and tenderness. Parotid gland was affected in 10 cases. An infectious cause for calculi was found in 7 while 3 presented calculi with no underlying infectious cause. Submaxillary gland was affected in 6 and sublingual in 2. No infectious condition was associated to submaxillary and sublingual calculi. Surgical treatment consisted in duct canalization for calculi removal and was performed in all patients after initial treatment with antibiotics. Neither complications nor relapse was found after surgical removal. Diagnosis of salivary calculi is made by clinical symptoms and imaging exams. Treatment is surgical and has to be performed after medical treatment for infection and inflamation.

    Aim: To audit the use of inferior vena cava (IVC) filter insertions at three UK centres over 12 years to assess whether trends in filter use in the UK mirrored those seen elsewhere. Materials and methods: Radiology department databases were interrogated for IVC filter insertions and removals between 1994 and 2006. Reports for these interventions, along with prior and subsequent imaging reports, were analysed. Follow-up data were obtained when available. Results: Five hundred and sixteen filters were placed with a significant year-on-year trend towards increasing use. Fifty-seven percent of filters placed were for absolute indications and 37% for relative indications. The filters were used for prophylaxis in 6% of patients in the absence of proven pulmonary embolism (PE) or deep vein thrombosis (DVT). A retrievable filter was used in 74% of cases with retrieval attempted in 40% of these and no evidence of an increasing rate of retrieval over time. A significant complication related to insertion or retrieval was encountered in 0.4 and 1% of procedures, respectively. Mean 24 h and 30 day mortalities were 1 and 8%, respectively. There was an absence of organized follow-up at all three centres. Conclusion: IVC filter use in the UK is increasing. The use of retrievable filters has not resulted in increased filter retrieval. Filter insertion and retrieval is associated with a low risk of significant complication, but lack of systematic follow-up limits conclusions regarding safety and efficacy.

    Pulmonary arterial hypertension (PAH) is associated with significant morbidity and mortality. In New Zealand, access to PAH-specific pharmacotherapy has been restricted for economic reasons. Since 2009, access to medication has been provided by a Special Authority scheme that ensures equity of access for all patients. Management of patients with PAH in this environment poses unique challenges. This study describes outcomes of patients managed in the Auckland PAH clinic over a 12-year period. The clinic database was interrogated. Patients were eligible for this study if they had PAH (World Health Organization (WHO) Class 1, 1' and 4) and had been managed in the clinic from the year 2000. One hundred and twenty-six patients (75% female, mean age at diagnosis 50) were included. Most had idiopathic PAH (37%) or PAH because of connective tissue disease (29%). At diagnosis, patients had advanced disease (median WHO Class III, 6-min walk distance 367 m and pulmonary vascular resistance of 10.6 Wood Units). Initial therapy was sildenafil in most cases. PAH-specific therapy was associated with improved WHO class and longer 6-min walk distance (P < 0.01 for both). Thirty per cent of patients were escalated to combination therapy. Survival was 91% at 1 year and 67% at 5 years. Despite historic difficulties with access to PAH-specific therapy, these data confirm benefits of therapy (primarily sildenafil as first-line treatment) for patients with PAH managed within the Auckland PAH clinic. Survival data are comparable with other reported cohorts. © 2012 The Authors; Internal Medicine Journal © 2012 Royal Australasian College of Physicians.

    Elevated atmospheric CO2 (eCO2) often increases photosynthetic CO2 assimilation (A) in field studies of temperate tree species. However, there is evidence that A may decline through time due to biochemical and morphological acclimation, and environmental constraints. Indeed, at the free-air CO2 enrichment (FACE) study in Oak Ridge, Tennessee, A was increased in 12-year-old sweetgum trees following 2 years of ∼40 % enhancement of CO2. A was re-assessed a decade later to determine if the initial enhancement of photosynthesis by eCO2 was sustained through time. Measurements were conducted at prevailing CO2 and temperature on detached, re-hydrated branches using a portable gas exchange system. Photosynthetic CO2 response curves (A versus the CO2 concentration in the intercellular air space (Ci); or A-Ci curves) were contrasted with earlier measurements using leaf photosynthesis model equations. Relationships between light-saturated photosynthesis (Asat), maximum electron transport rate (Jmax), maximum Rubisco activity (Vcmax), chlorophyll content and foliar nitrogen (N) were assessed. In 1999, Asat for eCO2 treatments was 15.4 ± 0.8 μmol m(-2) s(-1), 22 % higher than aCO2 treatments (P < 0.01). By 2009, Asat declined to <50 % of 1999 values, and there was no longer a significant effect of eCO2 (Asat = 6.9 or 5.7 ± 0.7 μmol m(-2) s(-1) for eCO2 or aCO2, respectively). In 1999, there was no treatment effect on area-based foliar N; however, by 2008, N content in eCO2 foliage was 17 % less than that in aCO2 foliage. Photosynthetic N-use efficiency (Asat : N) was greater in eCO2 in 1999 resulting in greater Asat despite similar N content, but the enhanced efficiency in eCO2 trees was lost as foliar N declined to sub-optimal levels. There was no treatment difference in the declining linear relationships between Jmax or Vcmax with declining N, or in the ratio of Jmax : Vcmax through time. Results suggest that the initial enhancement of photosynthesis to elevated CO2

    The aim of this study was to investigate the association between some educational indicators and dental caries experience of 12-year-old children in developing countries. The ecological association between DMFT levels amongst 12 year olds (DMFT-12 index) with six educational indicators (adult literacy rate, mean years of schooling, pupil-teacher ratio for primary level, educational expenditure as a percentage of gross national product, primary enrollment ratio and percent completing primary level) has been studied using developing countries as the unit of analysis. Pearson's correlation analysis and stepwise linear multiple regression technique were used to identify the significantly associated educational indicators with the DMFT-12 index. A negative association between DMFT-12 index and percent completing primary education level has been observed (r = -0.509; p education is significantly associated with DMFT-12 index scores (partial regression coefficient = -0.042; 95% confidence intervals: -0.064, -0.021). Dental caries experience of 12-year-old children appears to be highest in countries with low percent of primary level completion. Percent completing primary level education may be considered a good predictor of DMFT-12 index in developing countries.

A cohort of patients with Parkinson's disease received subthalamic nucleus deep brain stimulation from September 1998 to January 2010. Patient assessment data before and after the operation were collected prospectively. Forty-one patients (21 male and 20 female) with Parkinson's disease underwent bilateral subthalamic nucleus deep brain stimulation and were followed up for a median interval of 12 months. For the whole group, the mean improvements of Unified Parkinson's Disease Rating Scale (UPDRS) parts II and III were 32.5% and 31.5%, respectively (Pdeep brain stimulation protocol evolved and was substantiated by updated patient selection criteria and outcome assessment, integrated imaging and neurophysiological targeting, refinement of surgical technique as well as the accumulation of experience in deep brain stimulation programming. Most of the structural improvement occurred before mid-2005. Patients receiving the operation before June 2005 (19 cases) and after (22 cases) were compared; the improvements in UPDRS part III were 13.2% and 55.2%, respectively (Pdeep brain stimulation. A dedicated multidisciplinary team building, refined protocol for patient selection and assessment, improvement of targeting methods, meticulous surgical technique, and experience in programming are the key factors contributing to the improved outcome.

    Flap transposition is an infrequent but far from exceptional thoracic surgical procedure. The aim of this retrospective study was to report our experience in a referral unit of general thoracic surgery analyzing the early results after flap transposition. We retrospectively analyzed the clinical records, surgical notes, and postoperative results of a cohort of patients who underwent flap transposition in our unit from November 2000 to February 2013. Overall, a surgical approach adopting flap reconstruction techniques was performed in 81 patients (54 males, 27 females) with a median age of 62 years (range 20-87). Flap transposition was necessary to reconstruct chest wall after resection for malignancy (27 patients), to repair intrathoracic viscera perforation (15 patients), and to fill residual cavities secondary to pulmonary/pleural infection (39 patients). A pedicle muscle flap was transposed in most of cases (64 pts, 79 %), while in the remaining 17 cases (11 %), an omental flap was used. There were no immediate postoperative complications, while three in-hospital deaths occurred due to respiratory or multiorgan failure. Among patients undergone flap transposition to fill a residual cavity, we observed a recurrent bronchopleural fistula in three patients (7.7 %); such patients were treated by repeat flap transposition (2 cases) and by repeat cavernostomy (1 case). Flap transposition may be indicated as part of a multimodal treatment for severely ill patients requiring complex thoracic surgery.

    In response to the Bologna Declaration and contemporary trends in Animal Physiology education, the Animal Physiology course at the Faculty of Sciences, University of Novi Sad, Serbia, has evolved over a 12-yr period (2001-2012): from a classical two-semester course toward a one-semester course utilizing computer simulations of animal experiments, continual assessment, lectures, and an optional oral exam. This paper presents an overview of student achievement, the impact of reforms on learning outcomes, and lessons that we as educators learned during this process. The reforms had a positive impact on the percentage of students who completed the course within the same academic year. In addition, the percentage of students who completed the practical exam increased from 54% to >95% following the transition to a Bologna-based approach. However, average final grades declined from 8.0 to 6.8 over the same period. Students also appear reluctant to take the optional oral exam, and 82-91% of students were satisfied with the lower final grade obtained from only assessments and tests administered during the semester. In our endeavor to achieve learning outcomes set during the pre-Bologna period, while adopting contemporary teaching approaches, we sought to increase students' motivation to strive toward better performance, while ensuring that the increased quantity of students who complete the course is coupled with increased quality of education and a more in-depth understanding of animal physiology.

    All 583 attempts at endoscopic clearance of biliary calculi, performed in the Gastrointestinal Unit, Inselspital Bern, were retrospectively analyzed from 1980 until 1991. The average age of the patients was 70; 56% were female and 44% male. In 1980, 26 ERCPs for bile duct stone removal were performed, whereas in 1991 the number had increased to 90. The substantial increase in 1991 occurred after introduction of laparoscopic cholecystectomy. Over the total period of 12 years all stones were removed endoscopically after papillotomy in 82%, while the success rate in 1991 was 90%. Morbidity was 5.4% and lethality 0.2%. Total morbidity did not change markedly. However, the number of severe complications requiring surgical repair was reduced from 1.7% between 1980 and 1986 to 0% between 1987 and 1991. These results suggest that endoscopic removal of bile duct stones is increasingly performed with high success and low complication rates.

  15. Infliximab: 12 years of experience

    Science.gov (United States)

    2011-01-01

    Rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are immune-mediated conditions that share an inflammatory mechanism fuelled by excessive cytokines, particularly TNF. Control of inflammation and rapid suppression of cytokines are important in treating these diseases. With this understanding and the corresponding advent of TNF inhibitors, RA patients, AS patients and PsA patients have found more choices than ever before and have greater hope of sustained relief. As a widely used TNF inhibitor, infliximab has a deep and established record of efficacy and safety data. Extensive evidence - from randomised controlled clinical trials, large registries and postmarketing surveillance studies - shows that infliximab effectively treats the signs and symptoms, provides rapid and prolonged suppression of inflammation, prevents radiologically observable disease progression and offers an acceptable safety profile in RA, AS and PsA. In very recent studies, investigators have observed drug-free remission in some patients. Additionally, infliximab may interfere with rapidly progressing disease in RA by early addition to methotrexate in patients with signs of an aggressive course. Finally, infliximab has been shown to reduce PsA clinical manifestations such as nail involvement. With our current understanding, substantial data and increasing confidence regarding use in practice, infliximab can be considered a well-known drug in our continued campaign against inflammatory rheumatic diseases.

    Dental caries is the most prevalent disease in children. To determine the caries experience, prevalence, and severity in temporal and permanent dentition, likewise to establish the significant caries index in schoolchildren of Navolato, Sinaloa, Mexico as well as their treatment needs. A cross sectional study in 3048 schoolchildren aged 6 to 12 years. All subjects were clinically examined by three examiners (kappa>0.85), according to World Health Organization (WHO) guidelines. Caries detection criteria used were the WHO's criteria and Pitts' lesion d1. The mean age was 8.81 +/- 1.79 years old and 52.2% were girls. In the temporal dentition; the dmft was 4.68 +/- 3.21 and caries prevalence of 90.2% (dmft>3 was 60.8%, and dmft>6 was 27.4%). The overall significant caries index was 10.52 for 6 year olds. The noncavitated lesions (d1) represented 37.1% of the "decay" component. In the permanent dentition; the DMFT was 3.24 +/- 2.72 and caries prevalence was 82.0% (DMFT>3 was 47.8%, and DMFT>6 was 9.0%). The overall significant caries index was 10.87 for 12 year olds. The noncavitated lesions (d1) represented 63.4% of the "decay" component. The majority, 89.6% and 81.1% of children needed at least one restoration of one and two dental surfaces, respectively. Girls were more affected by caries than boys in permanent dentition, but not in temporal dentition. The caries experience increased with age. We observed high indices of caries, and high prevalence, severity and treatment needs. Noncavitated lesions were higher in permanent dentition that in primary dentition.

  18. Lambda Calculi: A Guide

    Hankin, Chris

    One of the universal notions of programming languages is functional abstraction. The methods of Java and the functions defined and used in functional programming languages, such as Haskell, are instances of this general notion. The inspiration for this form of abstraction mechanism comes from Mathematical Logic; notably Church's λ(lambda)-calculi and Schönfinkel's and Curry's Combinatory Logic. A proper study of these foundations leads to a better understanding of some of the fundamental issues in Computer Science.

  19. Observational Calculi and Association Rules

    Rauch, Jan

    2013-01-01

    Observational calculi were introduced in the 1960’s as a tool of logic of discovery. Formulas of observational calculi correspond to assertions on analysed data. Truthfulness of suitable assertions can lead to acceptance of new scientific hypotheses. The general goal was to automate the process of discovery of scientific knowledge using mathematical logic and statistics. The GUHA method for producing true formulas of observational calculi relevant to the given problem of scientific discovery was developed. Theoretically interesting and practically important results on observational calculi were achieved. Special attention was paid to formulas - couples of Boolean attributes derived from columns of the analysed data matrix. Association rules introduced in the 1990’s can be seen as a special case of such formulas. New results on logical calculi and association rules were achieved. They can be seen as a logic of association rules. This can contribute to solving contemporary challenging problems of data minin...

    Although children spend most of their time involved in activities related to school, few studies have focused on the association between school social environment and oral health. This cross-sectional study assessed individual and school-related social environment correlates of dental caries in Brazilian schoolchildren aged 8-12 years. A sample of children from 20 private and public schools (n=1,211) was selected. Socio-economic data were collected from parents, and data regarding children characteristics were collected from children using a questionnaire. Dental examinations were performed to assess the presence of dental plaque: dental caries experience (DMFT≥1) and dental caries severity (mean dmf-t/DMF-T). The social school environment was assessed by a questionnaire administered to school coordinators. Multilevel Poisson regression was used to investigate the association between school social environment and dental caries prevalence and experience. The dental caries prevalence was 32.4% (95% confidence interval: 29.7-35.2) and the mean dmf-t/DMF-T was 1.84 (standard deviation: 2.2). Multilevel models showed that the mean dmf-t/DMF-T and DMFT≥1 were associated with lower maternal schooling and higher levels of dental plaque. For contextual variables, schools offering after-hours sports activities were associated with a lower prevalence of dental caries and a lower mean of dmf-t/DMF-T, while the occurrence of violence and theft episodes was positively associated with dental caries. The school social environment has an influence on dental caries in children. The results suggest that strategies focused on the promotion of healthier environments should be stimulated to reduce inequalities in dental caries. © 2015 S. Karger AG, Basel.

  1. States in Process Calculi

    Full Text Available Formal reasoning about distributed algorithms (like Consensus typically requires to analyze global states in a traditional state-based style. This is in contrast to the traditional action-based reasoning of process calculi. Nevertheless, we use domain-specific variants of the latter, as they are convenient modeling languages in which the local code of processes can be programmed explicitly, with the local state information usually managed via parameter lists of process constants. However, domain-specific process calculi are often equipped with (unlabeled reduction semantics, building upon a rich and convenient notion of structural congruence. Unfortunately, the price for this convenience is that the analysis is cumbersome: the set of reachable states is modulo structural congruence, and the processes' state information is very hard to identify. We extract from congruence classes of reachable states individual state-informative representatives that we supply with a proper formal semantics. As a result, we can now freely switch between the process calculus terms and their representatives, and we can use the stateful representatives to perform assertional reasoning on process calculus models.

    We performed a review of the porphyrines content in a type of black, charcoal-like, renal calculi exhibiting infrared spectra (IRS) similar to those characteristic of "organic material" which has not yet been fully elucidate. Several other types of renal calculi, mainly those of small size, spontaneous passage renal stone, may also have diffuse or isolated dark charcoal components showing "organic material" IRS. After observing that haemoglobin has an "organic material" IRS, we studied, by a sensitive thin layer chromatography method, the presence of porphyrines in several types of dark or charcoal renal stones, since porphyrines are the physiological precursors of haemo group biosynthesis. We found two types of porphyrine content: coproporphyrin, in patients suffering from hepatopathy, and uroporphyrin and heptacarboxil-porphyrin in patients with some types of porphyria or with chronic renal failure.

    Background: Non-contrast thin-section helical CT has gained acceptance for the diagnosis of urinary tract calculi in adults, but experience with the technique in children is limited. Purpose: To evaluate the utility of non-contrast thin section helical CT for the diagnosis of urinary tract calculi in children. Materials and methods: Radiology databases at three pediatric institutions were searched to identify all pediatric patients evaluated by ''renal stone'' protocol CT scans (no oral or intravenous contrast, scans covering the entire urinary tract obtained in helical mode with narrow collimation (< 5 mm)). CT scans were reviewed for the primary finding of urinary tract calculi, for secondary signs of acute urinary tract obstruction and for evidence of alternative diagnoses. Medical records were reviewed to determine clinical presentation and to confirm the eventual diagnosis. Results: One hundred thirty-seven scans of 113 children (mean age: 11.2 years) were studied. Thirty-eight of 94 examinations (40%) performed on 82 children for acute pain and/or hematuria showed ureteral calculi. Alternative diagnoses were suggested by CT on 16 scans (17%). Twenty-eight scans were performed on 10 asymptomatic children with known calculus disease confirming renal stone burden on 21 scans (75%) and persistent ureteral calculi on 6 scans (21%). Upper tract calculi were demonstrated on 10 of 15 scans (67%) performed to evaluate for calculi in patients with known non-calculus genitourinary tract abnormalities. Conclusions: Non-contrast thin section helical CT is a useful method to diagnose urinary tract calculi in children. Radiation dose in this retrospective study may exceed the lowest possible radiation dose for diagnostic accuracy. Further research is needed to optimize CT imaging parameters, while maintaining diagnostic accuracy and minimizing radiation dose. (orig.)

    2016-11-15

    Pancreatolithiasis, or pancreatic calculi (PC), is a sequel of chronic pancreatitis (CP) and may occur in the main ducts, side branches or parenchyma. Calculi are the end result, irrespective of the etiology of CP. PC contains an inner nidus surrounded by successive layers of calcium carbonate. These calculi obstruct the pancreatic ducts and produce ductal hypertension, which leads to pain, the cardinal feature of CP. Both endoscopic therapy and surgery aim to clear these calculi and decrease ductal hypertension. In small PC, endoscopic retrograde cholangiopancreatography (ERCP) followed by sphincterotomy and extraction is the treatment of choice. Large calculi require fragmentation by extracorporeal shock wave lithotripsy (ESWL) prior to their extraction or spontaneous expulsion. In properly selected cases, ESWL followed by ERCP is the standard of care for the management of large PC. Long-term outcomes following ESWL have demonstrated good pain relief in approximately 60% of patients. However, ESWL has limitations. Per oral pancreatoscopy and intraductal lithotripsy represent techniques in evolution, and in current practice their use is limited to centers with considerable expertise. Surgery should be offered to all patients with extensive PC, associated multiple ductal strictures or following failed endotherapy.

    To determine the diagnostic value of ultrasound in patient with clinically suspected ureteral calculi, a prospective study was performed on 58 patients. Of these, 42 patients had 44 ureteral calculi and 16 patients had no calculi. The sonographic of a distal shadowign highly echogenic reflector along the ureter, with or without dilatation of the proximal ureter. Ultrasound correctly diagnosed 42 stones among 44 calculi and there was one false positive examination. The overall diagnostic accuracy was 95% Ultrasonography appears to be a very useful adjunct for the diagnosis of ureteral calculi when excretory urography is equivocal or contraindicated. Also ultrasonography was valuable in monitoring passage of radiolucent ureteral stones

  15. Stochastic Simulation of Process Calculi for Biology

    Directory of Open Access Journals (Sweden)

    Andrew Phillips

    2010-10-01

    Full Text Available Biological systems typically involve large numbers of components with complex, highly parallel interactions and intrinsic stochasticity. To model this complexity, numerous programming languages based on process calculi have been developed, many of which are expressive enough to generate unbounded numbers of molecular species and reactions. As a result of this expressiveness, such calculi cannot rely on standard reaction-based simulation methods, which require fixed numbers of species and reactions. Rather than implementing custom stochastic simulation algorithms for each process calculus, we propose to use a generic abstract machine that can be instantiated to a range of process calculi and a range of reaction-based simulation algorithms. The abstract machine functions as a just-in-time compiler, which dynamically updates the set of possible reactions and chooses the next reaction in an iterative cycle. In this short paper we give a brief summary of the generic abstract machine, and show how it can be instantiated with the stochastic simulation algorithm known as Gillespie's Direct Method. We also discuss the wider implications of such an abstract machine, and outline how it can be used to simulate multiple calculi simultaneously within a common framework.

    To assess accuracy of ultrasonographic (US) follow-up of distal ureteral calculi by using computed tomography (CT) and conventional radiography (kidneys, ureters, and bladder) as reference standards. The study was approved by the Regional Ethics Committee, and written informed consent was obtained. One hundred fifty-eight patients with CT-diagnosed symptomatic ureteral calculi, for whom follow-up imaging was ordered, were enrolled from February 2006 to December 2008. Six were excluded, having not met study entry criteria, with 121 men (mean age, 49 years; range, 20-91 years) and 31 women (mean age, 44 years; range, 34-77 years) completing the protocol with adequate reference standard imaging. Targeted transabdominal US occurred coincidently with follow-up CT (n = 92) or radiography (n = 60), with US evaluation prospectively compared considering sensitivity and specificity. Statistical analysis was performed with a χ(2) test, t test, or paired t test, as appropriate. Results of nine US examinations were nondiagnostic because of inadequate ureteral visualization, and among these, two cases showed residual distal calculi. Of the remaining 143 patients, 33 had residual distal calculi, all visualized with US. There was a single false-positive study, giving sensitivity, including nondiagnostic US examinations, of 94.3% (95% confidence interval [CI]: 80.8%, 99.3%) and specificity of 99.1% (95% CI: 95.3%, 100%). All calculi appeared hyperechoic with posterior acoustic shadowing. Additional diagnostic features included presence of a hypoechoic rim and Doppler twinkle artifact. Mean stone length was 7.2 mm ± 2.6 (standard deviation) (range, 4-18 mm). Mean ureteral length visualized was 36.4 mm (range, 12-77 mm), with calculi positioned at a mean of 13.1 mm ± 11.2 (range, 0-40 mm) from the ureterovesical junction (UVJ). Nondiagnostic results were more likely with bladder volume of 110 mL or less (eight [16%] of 50 vs one [1%] of 102, P = .0009). Ureteral calculi within 35

    Full Text Available Purpose In this paper we present our experience with dissolution therapy of radiolucent calculi. Materials and Methods This was a retrospective analysis of patients who were offered urinary dissolution therapy between January 2010 and June 2011. Patients were treated with tablets containing potassium citrate and magnesium oxide. Partial dissolution was defined as at least a 50% reduction in stone size. Patients with complete or partial dissolution were classified in the successful dissolution group. Patients with no change, inadequate reduction, increase in stone size and those unable to tolerate alkali therapy were classified as failures. Patient sex, stenting before alkalinization, stone size, urine pH at presentation and serum uric acid levels were analyzed using Fisher t-test for an association with successful dissolution. Results Out of 67, 48 patients reported for follow up. 10 (15% had complete dissolution and 13 (19% had partial dissolution. Alkalinization was unsuccessful in achieving dissolution in 25 (37%. Stenting before alkalinization, patient weight ( 75kg and serum uric acid levels (≤ 6 vs. > 6 were the only factors to significantly affected dissolution rates (p = 0.039, p 0.035, p 0.01 respectively. CONCLUSIONS A policy of offering dissolution therapy to patients with radiolucent calculi had a successful outcome in 34% of patients.

    1983-10-01

    Eight male patients on clean intermittent catheterization programs for neurogenic bladder dysfunction developed vesical calculi around pubic hairs inadvertently introduced into the bladder, acting as a nidus for incrustation. In three patients, the radiographic appearance of serpentine calcifications in the pelvis was highly consistent with calcareous deposits on strands of hair. Familiarity with this radiologic appearance should suggest the diagnosis in the appropriate clinical setting and help avoid misinterpretation of these calcifications, atypical of usual bladder stones.

    Full Text Available We describe the case of a patient with calcium oxalate monohydrate and calcium oxalate dihydrate calculi occluded in cavities. All those calculi were located inside narrow cavities covered with a thin epithelium that permits their visualization. Urinary biochemical analysis showed high calciuria, not hypercalciuria, hypocitraturia, and a ratio [calcium]/[citrate] >0.33. The existence of cavities of very low urodynamic efficacy was decisive in the formation of such calculi. It is important to emphasize that we observed a thin epithelium covering such cavities, demonstrating that this epithelium may be formed after the development of the calculi through a re-epithelialization process.

  3. Intersection Type Systems and Explicit Substitutions Calculi

    Science.gov (United States)

    Ventura, Daniel Lima; Ayala-Rincón, Mauricio; Kamareddine, Fairouz

    The λ-calculus with de Bruijn indices, called λ dB , assembles each α-class of λ-terms into a unique term, using indices instead of variable names. Intersection types provide finitary type polymorphism satisfying important properties like principal typing, which allows the type system to include features such as data abstraction (modularity) and separate compilation. To be closer to computation and to simplify the formalisation of the atomic operations involved in β-contractions, several explicit substitution calculi were developed most of which are written with de Bruijn indices. Although untyped and simply types versions of explicit substitution calculi are well investigated, versions with more elaborate type systems (e.g., with intersection types) are not. In previous work, we presented a version for λ dB of an intersection type system originally introduced to characterise principal typings for β-normal forms and provided the characterisation for this version. In this work we introduce intersection type systems for two explicit substitution calculi: the λσ and the λs e . These type system are based on a type system for λ dB and satisfy the basic property of subject reduction, which guarantees the preservation of types during computations.

    2010-09-01

    Within the framework of basic-deformed and finite-difference calculi, as well as deformation procedures proposed by Tsallis, Abe, and Kaniadakis and generalized by Naudts, we develop field-theoretical schemes of statistically distributed fields. We construct a set of generating functionals and find their connection with corresponding correlators for basic-deformed, finite-difference, and Kaniadakis calculi. Moreover, we introduce pair of additive functionals, which expansions into deformed series yield both Green functions and their irreducible proper vertices. We find as well formal equations, governing by the generating functionals of systems which possess a symmetry with respect to a field variation and are subjected to an arbitrary constrain. Finally, we generalize field-theoretical schemes inherent in concrete calculi in the Naudts manner. From the physical point of view, we study dependences of both one-site partition function and variance of free fields on deformations. We show that within the basic-deformed statistics dependence of the specific partition function on deformation has in logarithmic axes symmetrical form with respect to maximum related to deformation absence; in case of the finite-difference statistics, the partition function takes non-deformed value; for the Kaniadakis statistics, curves of related dependences have convex symmetrical form at small curvatures of the effective action and concave form at large ones. We demonstrate that only moment of the second order of free fields takes non-zero values to be proportional to inverse curvature of effective action. In dependence of the deformation parameter, the free field variance has linearly arising form for the basic-deformed distribution and increases non-linearly rapidly in case of the finite-difference statistics; for more complicated case of the Kaniadakis distribution, related dependence has double-well form.

    2011-07-09

    Macroscopic renal calculi were seen in 50 of 492 (10.2 per cent) wild Eurasian otters found dead in England from 1988 to 2007. Forty-eight adults and two subadults were affected. Calculi were present in 15.7 per cent (31 of 197) of adult males and 12.7 per cent (17 of 134) of adult females. There was an increase in prevalence in the study population over time; no calculi were found in 73 otters examined between 1988 and 1996, but in most subsequent years they were observed with increased frequency. Calculi occurred in both kidneys but were more common in the right kidney. They varied greatly in shape and size; larger calculi were mostly seen in the calyces while the smallest ones were commonly found in the renal medulla. Calculi from 45 cases were examined by x-ray diffraction analysis; in 43 (96 per cent), they were composed solely of ammonium acid urate. Affected otters had heavier adrenal glands relative to their body size than unaffected otters (P0.05). Many otters had fresh bite wounds consistent with intraspecific aggression. The proportion bitten increased over time and this coincided with the increased prevalence of renal calculi.

    The purpose of this study was to determine the frequency of scrotal calculi in men referred for scrotal ultrasonography (US), to identify any associated pathologies, and to investigate if any relationship exists between scrotal lithiasis and pain. This was a retrospective study in which 4084 scrotal US examinations in 3435 men were evaluated. Scrotal US was performed using a high-frequency linear transducer. Forty patients were questioned as to whether scrotal pain was present. Patients were asked to grade their scrotal pain intensity using the Numerical Rating Scale. Sixty-seven of the 3435 patients with scrotal US examinations had scrotal calculi with a mean size of 3.7 ± 1.4 mm (range, 1.6-7 mm). Twenty patients with scrotal calculi had no scrotal pain. Nine patients with scrotal pain (22.5%) had no US or clinical abnormalities except scrotal calculi. The frequency of scrotal calculi was 1.95%. Approximately one-quarter of patients with scrotal calculi and pain had no additional abnormalities. Therefore, scrotal calculi should be considered in the differential diagnosis of scrotal pain.

    Calculi removed from human prostates affected with nodular hyperplasia were analyzed with scanning electron microscopy and EDAX system. The general spectrum was made up of Na, Al, Mg, S, P, Ca and Zn. Two types of stone were identified morphostructurally and microanalytically: calculi type I of nodular surface with high peaks of S, and calculi type II polyfaceted with high peaks of P and Ca. Their formation from corpora amylacea and/or exogenous constituents is discussed. The superficial deposit of Zn suggests its incorporation from the prostatic liquid and does not seem to play an important role in the genesis.

    Percutaneous ultrasonic lithotripsy of upper urinary tract lithiasis is a well-established procedure in adults. We successfully applied this technique to completely remove symptomatic renal calculi in two children with idiopathic hypercalciuria. The procedure was well tolerated and no complications occurred. Both patients were discharged within 4 days of the lithotripsy. This method is an alternative to surgery for the removal of large or impacted calculi from the upper urinary tracts of pediatric patients. (orig.).

    The purpose of the study is to develop an algorithm for the segmentation of renal calculi on ureteroscopic images. In fact, renal calculi are common source of urological obstruction, and laser lithotripsy during ureteroscopy is a possible therapy. A laser-based system to sweep the calculus surface and vaporize it was developed to automate a very tedious manual task. The distal tip of the ureteroscope is directed using image guidance, and this operation is not possible without an efficient segmentation of renal calculi on the ureteroscopic images. We proposed and developed a region growing algorithm to segment renal calculi on ureteroscopic images. Using real video images to compute ground truth and compare our segmentation with a reference segmentation, we computed statistics on different image metrics, such as Precision, Recall, and Yasnoff Measure, for comparison with ground truth. The algorithm and its parameters were established for the most likely clinical scenarii. The segmentation results are encouraging: the developed algorithm was able to correctly detect more than 90% of the surface of the calculi, according to an expert observer. Implementation of an algorithm for the segmentation of calculi on ureteroscopic images is feasible. The next step is the integration of our algorithm in the command scheme of a motorized system to build a complete operating prototype.

    1991-01-01

    In a series gathered over 5 years (November 1984 to November 1989), we have treated 356 patients with ureteral lithiasis. Out of these, 170 (134 men and 36 women) were treated with extracorporeal shock-wave lithotrity with a Dornier HM3 system, in situ and as a first intention. The calculi (176 stones) were regularly distributed along the ureter: their location was subpyelic in 44 cases, lumboiliac in 59, upper pelvic in 42 and lower pelvic in 32. The average diameter of the calculi was 10 mm for subpyelic stones and 8 mm for the others. A preliminary urine drainage was required for 24 calculi causing acute obstructive pyelonephritis (32 ureteral drains surrounding the stone, and 2 percutaneous nephrostomies). Radioscopic localization required intravenous pyelography during lithotrity in 52 cases (30%). On radiographs without preparation taken the next day, 170 stones were regarded as fragmented (96%). After some time the 6 patients whose calculus had not been fragmented underwent another treatment (4 ureterotomies and 2 ureteroscopies). Five patients had an additional treatment because of a painful and/or febrile episode (3 drain insertions and 2 ureterotomies) and 2 patients required a second session of lithotrity because fragmentation was not sufficient; 4 patients were lost to follow-up. A total of 153 patients (90%) got rid of their fragments, 146 during the first months and the remaining 7 before the sixth month. No severe complication was noted. Besides the 5 patients who had required additional treatment, 11 patients suffering from pain and/or fever had a medical treatment. These treatments lead us to proposing first-intention "in situ" extracorporeal shock wave lithotrity for all ureteral lithiases requiring a treatment.

  15. Existence families, functional calculi and evolution equations

    CERN Document Server

    deLaubenfels, Ralph

    1994-01-01

    This book presents an operator-theoretic approach to ill-posed evolution equations. It presents the basic theory, and the more surprising examples, of generalizations of strongly continuous semigroups known as 'existent families' and 'regularized semigroups'. These families of operators may be used either to produce all initial data for which a solution in the original space exists, or to construct a maximal subspace on which the problem is well-posed. Regularized semigroups are also used to construct functional, or operational, calculi for unbounded operators. The book takes an intuitive and constructive approach by emphasizing the interaction between functional calculus constructions and evolution equations. One thinks of a semigroup generated by A as etA and thinks of a regularized semigroup generated by A as etA g(A), producing solutions of the abstract Cauchy problem for initial data in the image of g(A). Material that is scattered throughout numerous papers is brought together and presented in a fresh, ...

    2012-12-01

    To determine caries prevalence and caries experience in 12-year-old children living in the Republic of Cyprus and to evaluate whether different variables were associated with caries experience. According to the WHO recommendation, schools were randomly selected by taking into account the distribution between rural and urban regions, so that 10% of Cypriot children attending the sixth grade could be examined. In the school year 2003/2004 the children were examined in schools by one person with the aid of artificial light but without taking radiographs or fibre-optic transillumination. DMFT, presence of fissure sealants and black stain were recorded. In total 951 children were examined. Caries prevalence was 32.6% (95% CI 29.62-35.6). The mean DMFT was 0.65 (sd 1.17) and the SiC was 1.95. Fissure sealants were found in 14.3% of the children. No association between frequency of tooth brushing, presence of fissure sealants or presence of black stain and caries experience was observed. Children living in rural areas had significantly higher mean DMFT values than children living in urban areas. A further caries decline may be attained by promoting a more extensive use of preventive measures like application of fluoride varnish or fissure sealants.

  18. Labelled Lambda-calculi with Explicit Copy and Erase

    2010-03-01

    Full Text Available We present two rewriting systems that define labelled explicit substitution lambda-calculi. Our work is motivated by the close correspondence between Levy's labelled lambda-calculus and paths in proof-nets, which played an important role in the understanding of the Geometry of Interaction. The structure of the labels in Levy's labelled lambda-calculus relates to the multiplicative information of paths; the novelty of our work is that we design labelled explicit substitution calculi that also keep track of exponential information present in call-by-value and call-by-name translations of the lambda-calculus into linear logic proof-nets.

    2013-03-26

    A 60-year-old woman presented with complaints of intermittent right flank pain which had begun one year ago. Ultrasonography and intravenous urogram showed right pelvic (15 mm) and inferior calyceal (6 mm) calculi along with suspected retrocaval course of right ureter, which was confirmed by contrast CT scan. Tc-99m diethylene-triamine-penta-acetic acid (DTPA) scan showed normal function and normal drainage of right kidney. Percutaneous nephrolithotomy (PCNL) was performed for right renal calculi. Because of curved ureteric course, negotiation of ureteric catheter in pelvis was anticipated to be troublesome, so intraoperative retrograde pyelogram (RGP) was performed to delineate the anatomy. Puncture was performed safely after air contrast pyelography. No complications occurred intraoperatively and postoperatively. On follow-up of up to 1 year patient was asymptomatic and renal scan showed normal function and drainage. So in the presence of retrocaval ureter and associated renal calculi, PCNL is a safe and optimal procedure and in condition of non-obstructive drainage, management of calculi only is adequate.

    Of 5 analysis tests of the 3rd International Ring Experiment for the control of the quality of methods of the analysis of urinary calculi 38 findings compiled according to 9 different techniques came in from 12 countries. The average deviation per component concerning all 5 analysis tests is considerably low with 0.10 mol proportions. The average quality measure SQ concerning all participants is approximately 2.00; it deteriorates from the X-ray diffraction method over the IR-technique to the other quantitative methods used. Advantages and disadvantages of the X-ray diffraction and IR-spectroscopic analysis are discussed. A methodically homogeneous and centralized performed analysis of urinary calculi shows advantages in the quality of the analyses.

    Full Text Available Context: There has been a paradigm shift in the management of ureteral calculi in the last decade with the introduction of new less invasive methods, such as ureterorenoscopy and extracorporeal shock wave lithotripsy (ESWL. Aims: Recent studies have reported excellent results with medical expulsive therapy (MET for distal ureteral calculi, both in terms of stone expulsion and control of ureteral colic pain. Settings and Design: We conducted a comparative study in between watchful waiting and MET with tamsulosin. Materials and Methods: We conducted a comparative study in between watchful waiting (Group I and MET with tamsulosin (Group II in 60 patients, with a follow up of 28 days. Statistical Analysis: Independent ′t′ test and chi-square test. Results: Group II showed a statistically significant advantage in terms of the stone expulsion rate. The mean number of episodes of pain, mean days to stone expulsion and mean amount of analgesic dosage used were statistically significantly lower in Group II (P value is 0.007, 0.01 and 0.007, respectively as compared to Group I. Conclusions: It is concluded that MET should be considered for uncomplicated distal ureteral calculi before ureteroscopy or extracorporeal lithotripsy. Tamsulosin has been found to increase and hasten stone expulsion rates, decrease acute attacks by acting as a spasmolytic, reduces mean days to stone expulsion and decreases analgesic dose usage.

    2001-01-01

    Full Text Available There is a paucity of cost-effectiveness studies in India comparing PCNL and ESWL in the treatment of renal cal-culi. We are dependent on costing studies from western literature, although the nature of expenses in developed countries is quite different from those in India. This study compares the two procedures with regards to cost-effec-tiveness & efficacy in clearing medium-sized renal calculi (2.0 cms at our institute. All costs borne by the patient & the institute were taken into account, including equip-ment costs, stay charges & cost of travel incurred, for re-peat visits to the institute. The groups compared had similar stone characteristics & were from our early experience with the two methods. All costing was done at 1998 rates by submitting case sheets to a fresh billing. PCNL, was significantly more efficient at clearing calculi (94% vs 69% than ESWL, but patients needed hospitalization. The re-quirement of ancillary procedures was significantly less with PCNL than ESWL (1 vs 35 and ESWL was more expensive although the difference was not statistically sig-nificant. High initial cost of a lithotripter along with the need for repeated visits to the hospital for clearance of the calculus contribute to the increased cost of ESWL. PCNL ensures clearance of calculi at a single hospital admission with minimal morbidity.

    A common clinical finding is that many schoolchildren display a nonacceptable oral hygiene. To evaluate the tooth-brushing behaviour in children aged 6-12 years. The study used a cross-sectional descriptive design. Children aged 6, 8, 10, and 12 years in an elementary school in a middle class area in Umeå, a city in northern Sweden, were invited and 82 (82%) consented. Visible plaque on buccal surfaces of incisors and canines was recorded from photographs of the participant's teeth before and after brushing using the scores of the Green and Vermillion Oral Hygiene Index. Brushing technique was recorded with a video camera. A questionnaire was used to collect data about oral hygiene habits at home. The ratio between the sum of plaque scores after and before brushing was statistically significantly higher in the 6-year-old group compared with the 10-year olds, (P brushing and the ratio between the sum of plaque scores after and before brushing (r = -0.31, P 0.05). Six-year olds spent statistically significantly less time for brushing than older children (P brushing was poor and averaged 19% for 6-year olds and 30% for older children. The results of brushing for children aged 8-12 years could benefit from increasing tooth-brushing time. Children could be given an increasing responsibility from 7 to 8 year of age but parental help is motivated up to 10 years of age. © 2010 The Authors.

    The hearing disorders of the child between 3 and 12 years are dominated by the conductive hearing loss. The questioning, looking for risk factors, as well as the otoscopy are essential to detect and diagnose a hearing disorder. Screening tests help to identify the children with risk of hearing loss. Then, the child is sent for diagnosis towards an ENT specialist or a specialized structure. In spite of the frequency of the conductive hearing loss, in case of the slightest doubt, a sensorineural hearing loss must be always looked for by a puretone audiometry examination via the headphones.

    To evaluate the long-term risk of recurrence of calcium oxalate (CaOx) cystic calculi in dogs of various breeds fed 1 of 2 therapeutic diets. Retrospective cohort study. Animals-135 dogs with a history of CaOx cystic calculi. Medical records for 4 referral hospitals were searched to identify dogs that had had CaOx cystic calculi removed. Owners were contacted and medical records evaluated to obtain information on postoperative diet, recurrence of signs of lower urinary tract disease, and recurrence of cystic calculi. Dogs were grouped on the basis of breed (high-risk breeds, low-risk breeds, and Miniature Schnauzers) and diet fed after removal of cystic calculi (diet A, diet B, and any other diet [diet C], with diets A and B being therapeutic diets formulated to prevent recurrence of CaOx calculi). Breed group was a significant predictor of calculi recurrence (as determined by abdominal radiography or ultrasonography), with Miniature Schnauzers having 3 times the risk of recurrence as did dogs of other breeds. Dogs in diet group A had a lower prevalence of recurrence than did dogs in diet group C, but this difference was not significant in multivariable analysis. Results indicated that Miniature Schnauzers had a higher risk of CaOx cystic calculi recurrence than did dogs of other breeds. In addition, findings suggested that diet may play a role in decreasing recurrence, but future prospective studies are needed to validate these observations.

    To determine if calcium deposits in the papillae can be identified by unenhanced computed tomography (uCT) even before renal stones develop. A retrospective review of 413 patients with calculi identified 31 patients (stone-forming group) with a history of urinary tract calculi with a calculus demonstrated by uCT and a stone-free uCT before calculi had developed. The control group (n = 31) was composed of live kidney donors with no history of calculi and a stone-free uCT. CT attenuation was measured in all CTs using two regions of interest of 0.05 cm{sup 2} and 0.1 cm{sup 2} over the tip and the neighbouring area of the papillae. Student's and Wilcoxon t-tests were used for comparing results in the two groups. The attenuation of the tip of the papilla was higher in the stone-forming group when compared to the controls after (45.2 HU versus 32.1 HU, P = 0.001) and even before frank calculi had developed (44.2 HU versus 32.1 HU, P = 0.003). There was no significant difference in papillary attenuation in the stone group before and after calculi had developed (45.2 HU versus 44.2 HU, P = 0.82). Stone-forming patients exhibit higher papillary density even before calculi develop. This could define a population at risk of developing calculi. (orig.)

    Full Text Available Calcium oxalate monohydrate (COM renal calculi can be classified into two groups: papillary and nonpapillary. In this paper, a comparative study between etiologic factors of COM papillary and nonpapillary calculi is performed. The study included 40 patients with COM renal calculi. The urine of these individuals was analyzed. Case history, lifestyle, and dietetic habits were obtained.No significant differences between urinary biochemical data of both groups were observed; 50% of COM papillary stone formers and 40% of COM nonpapillary stone formers had urolithiasis family history. A low consumption of phytate-rich products was observed for both groups. A relationship between profession with occupational exposure to cytotoxic products and COM papillary renal lithiasis was detected.The results suggest that COM papillary calculi would be associated to papillary epithelium alterations together with a crystallization inhibitors deficit, whereas COM nonpapillary calculi would be associated to the presence of heterogeneous nucleants and a crystallization inhibitors deficit.

    Due to the increase in the number of urinary calculi disease cases in Jordan, stone samples were collected from patients from various Jordanian hospitals (Princes Basma (PBH), King Abdullah University (KAUH), Al-Basheer (ABH) and Al-Mafraq (AMH)). This study concentrates on the effect of trace metals in patients of urinary calculi. Trace metals were detected in 110 urinary calculi samples using X-ray fluorescence (XRF) and atomic absorption spectroscopy (AAS) techniques. Of the calculi examined, 21 were pure calcium oxalate (CaOax), 29 were mixed calcium oxalate/uric acid, 23 were mixed calcium oxalate/phosphate (apatite), 25 were phosphate calculi (apatite/struvite), five were mixed calcium oxalate monohydrate/struvite, four were urate calculi (mixed ammonium acid urate/sodium acid urate) and three were pure cystine calculi. The concentration measurement of Ca and other trace metals levels has been found useful in understanding the mechanism of stone formation and in evaluating pathological factors. It has been found that Ca is the main constituent of the urinary calculi, especially those stones composed of calcium oxalate and calcium phosphate. The concentration of most of the trace metals that were analyzed was (Ca = 48.18, Na = 1.56, K = 0.9, Mg = 3.08, Fe = 1.17, Al = 0.49, Zn = 0.7, Cu = 0.19, Mn = 0.029, P = 10.35, S = 1.88, Sr = 0.306, Mo = 0.2, Cr = 0.146, Co = 0.05, Ni = 0.014)%. In conclusion, metals concentration in Jordanian patient's urinary calculi samples was higher than its equivalents of other patients'. It has been noted that there is no concentration of toxic trace elements (like Li, V, Pb, Cd, and As). Some heavy metals, however, were detected Mo, Cr, Co and Ni as traces. P and S ions are present in few calculi stones as traces.

    Objective: A meta-analysis was conducted to determine the accuracy of dual-energy computed tomography (DECT) for differentiating urinary uric acid and calcified calculi. Methods: The databases PubMed, EMBASE, Web of Science, and the Cochrane Library were searched up to May 2016 for relevant original studies. Data were extracted to calculate the pooled sensitivity, specificity, diagnostic odds ratio (OR), positive and negative likelihood ratios (PLR and NLR), and areas under summary receiver operating characteristic (AUROC) curves for analysis. Results: Nine studies (609 stones in 415 patients) were included. For differentiating uric acid (UA) and non-UA calculi with DECT, the analysis indicated: pooled weighted sensitivity, 0.955 (95% CI, 0.888–0.987); specificity, 0.985 (95% CI, 0.970–0.993); PLR, 0.084 (95% CI, 0.041–0.170); NLR 33.327 (95% CI, 18.516–59.985); and diagnostic OR 538.18 (95% CI, 195.50–1478.5). The AUROC value was 0.9901. For calcified stones, the analysis indicated: pooled weighted sensitivity, 0.994 (95% CI, 0.969–1); specificity, 0.973 (95% CI, 0.906–0.997); PLR, 11.200 (95% CI, 4.922–25.486); NLR 0.027 (95% CI, 0.010–0.072); and diagnostic OR 654.89 (95% CI, 151.31–2834.4). The AUROC value was 0.9915. Conclusion: This meta-analysis found that DECT is a highly accurate noninvasive method for characterizing urinary uric acid and calcified calculi.

    Full Text Available We describe a case of a giant conjunctival nevus presented in a 12-year-old girl with suspicious clinicomorphological appearance. The lesion was noticed by the parents at the age of 3 years as a “fleshy spot” on the bulbar conjunctiva. The lesion remained unchanged until approx. 6 months before recent admission. On slit-lamp examination, a large conjunctival lesion with variegate pigmentation and indistinct margins was detected on the superonasal part of the bulbar conjunctiva of the left eye. Intralesional cysts and vessels were detected with AS-OCT examination. Wide excision and cryotherapy to the scleral bed were performed and amniotic membrane graft was used to restore the ocular surface. Histopathological examination revealed compound type conjunctival nevus and disclosed any sign of malignancy. Although giant conjunctival nevus is a rare entity, precise diagnosis and adequate management are very important as it can be confused with malignant melanoma.

    Information about the long-term clinical survival of large amalgam and composite restorations is still lacking. This retrospective study compares the longevity of three- and four-/five-surface amalgam and composite restorations relative to patients' caries risk. Patient records from a general practice were used for data collection. We evaluated 1949 large class II restorations (1202 amalgam/747 composite). Dates of placement, replacement, and failure were recorded, and caries risk of patients was assessed. Survival was calculated from Kaplan-Meier statistics. After 12 years, 293 amalgam and 114 composite restorations had failed. Large composite restorations showed a higher survival in the combined population and in the low-risk group. For three-surface restorations in high-risk patients, amalgam showed better survival.

    OBJECTIVE. To characterize utilization of oral hygiene devices and customs in schoolchildren. MATERIAL AND METHODS. We performed a cross-sectional study in 1,404 schoolchildren (6- 12 year olds) from 14 public schools in Pachuca, Hidalgo, México, using a questionnaire for sociodemographic variables and 1) Tooth brushing frequency (customs were 85.5% tooth brushing, 90.9% toothpaste, 19.4% flossing, and 28.2% mouthwash. Only 11.8% of participants reported utilization in all 4 categories. We observed differences (p < 0.05) across sexes only in the use of toothpaste, as women used it more often. Differences across age were observed (p < 0.05) for tooth brushing (younger children brushed more often) and flossing (older children flossed more often). CONCLUSIONS. Tooth brushing was the oral hygiene practice more often performed in this sample, with other frequencies being relatively low. There were differences by age and sex across some variables.

    Scrotal calculi are rare, and their clinical significance is uncertain. Scrotal pain is a frequent, hard-to-manage problem in urology clinics. Our purpose in this study was to determine the relationship between the presence of scrotal calculi and scrotal pain in a prospective manner. Sonography and color Doppler ultrasound of the scrotum were performed in 758 consecutive patients referred with scrotal pain. The pain was rated by using an 11-point numeric rating scale; scores were compared among patients with scrotal calculi with and without additional scrotal pathology. Scrotal calculi were detected in 73 of the 758 patients (9.6%). Scrotal pain (n = 50 [61%]) and a palpable mass in the scrotum (n = 25 [30.5%]) were the most common complaints in patients with scrotal calculi. Hydrocele (n = 17 [29.8%]) and varicocele (n = 15 [26.3%]) were the most commonly associated abnormalities; there was a statistically significant association between the presence of scrotal calculi and hydrocele (p pain was present in 61 (83.5%) patients with scrotal calculi, and this association was significant (p pain and the correlation between location of calculi and pain in patients without additional scrotal abnormalities were also significant (p = 0.04 and p pain. Because the etiology of scrotal pain is essential for appropriate treatment, scrotal calculi should be kept in mind when making a differential diagnosis of scrotal pain. © 2014 Wiley Periodicals, Inc.

    The objectives of this research were: 1) to determine whether there were differences in empathy according to gender; 2) to analyze the relationships between empathy and social behaviour, self-concept, emotional stability, social interaction strategies, capacity to analyze emotions, intelligence, and creativity; and 3) to identify predicting variables of empathy. The sample consisted of 139 participants aged 10 to 12 years. ANOVA results showed gender differences in empathy, with significantly higher scores in females. Pearson coefficients suggest that participants with high empathy showed many positive social behaviours (prosocial, assertive, consideration, self-control, leadership), few negative social behaviors (passive, aggressive, antisocial, withdrawal) and many assertive strategies of social interaction; that they were named as prosocial classmates; and that they had high self-concept, high capacity to analyze negative emotions, high emotional stability and many behaviors and traits of creative personality. Multiple regression analyses permitted identification of the following predicting variables of empathy: high level of prosocial behaviour, low level of aggressive behaviour and high self-concept.

    Muscular hypertrophy secondary to denervation is very rare, but well-documented phenomena in adults. This is the first report of a child with neurogenic unilateral hypertrophy due to S1 radiculopathy. A 12-year-old girl presented with left calf hypertrophy and negative history of low back pain or trauma. The serum creatinine kinase level and inflammatory markers were normal. Magnetic resonance imaging showed muscle hypertrophy of the left gastrocnemius and revealed a protruded lumbar disc at the L5-S1 level. The protruded disc abuts the S1 root on the left side. Electromyography showed mild left S1 radiculopathy. Passive stretching and work load might clarify the origin of neurogenic hypertrophy but there is still a need for further evidence. Clinical, laboratory, magnetic resonance imaging and electromyography findings showed that S1 radiculopathy could be a cause of unilateral calf swelling in youth even in the absence of a history of back or leg pain.

    Exposure to metallic mercury can cause severe accidental intoxications in children, whose clinical symptoms can vary depending on the route of administration, the dose, as well as the time and duration of the exposure. It has become unusual in France, yet it must be considered when taking a patient's medical history in cases of multisystemic involvement without a clear explanation. We report the case of a 12-year-old patient hospitalized because of a cough, poor general condition, chills, night sweats, psychomotor retardation, and skin lesions that had been developing for several weeks. The initial clinical examination also revealed sinus tachycardia, arterial hypertension, and abolition of osteotendinous reflexes. Complementary examination results were normal apart from a glomerular proteinuria without renal failure. When interviewing the mother, she reported that the child had played with mercury balls 3 months earlier. The suspicion of poisoning was confirmed by blood and urine analysis as well as renal biopsy showing an aspect of membranous glomerulonephritis with IgG and C3 depositions. An intoxication via a transdermal route being unlikely on healthy skin, the Regional Health Agency's survey concluded that chronic intoxication had occurred by inhalation of the mercury spread on the floor at the time of the exposure, which was then vacuum cleaned and released again by the contaminated vacuum cleaner. The patient's outcome was favorable within a few weeks after initiating DMSA chelation therapy. Mercury poisoning should be considered in cases of a multisystemic disorder without clear explanation, in order to intervene quickly and thus prevent irreversible renal and neurological consequences.

    The identification and evaluation of activities capable of dislodging calyceal renal calculi require a patient surrogate or validated functional pyelocalyceal renal model. To evaluate roller coaster facilitation of calyceal renal calculi passage using a functional pyelocalyceal renal model. A previously described adult ureteroscopy and renoscopy simulator (Ideal Anatomic) was modified and remolded to function as a patient surrogate. Three renal calculi of different sizes from the patient who provided the original computed tomographic urograph on which the simulator was based were used. The renal calculi were suspended in urine in the model and taken for 20 rides on the Big Thunder Mountain Railroad roller coaster at Walt Disney World in Orlando, Florida. The roller coaster rides were analyzed using variables of renal calculi volume, calyceal location, model position on the roller coaster, and renal calculi passage. Sixty renal calculi rides were analyzed. Independent of renal calculi volume and calyceal location, front seating on the roller coaster resulted in a passage rate of 4 of 24. Independent of renal calculi volume and calyceal location, rear seating on the roller coaster resulted in a passage rate of 23 of 36. Independent of renal calculi volume in rear seating, calyceal location differed in passage rates, with an upper calyceal calculi passage rate of 100%; a middle calyceal passage rate of 55.6%; and a lower calyceal passage rate of 40.0%. The functional pyelocalyceal renal model serves as a functional patient surrogate to evaluate activities that facilitate calyceal renal calculi passage. The rear seating position on the roller coaster led to the most renal calculi passages.

    To assess the possible nature and role of trace elements in the pathogenesis of urinary stones. A series of 76 calculi from the East-Algerian region has been investigated through Fourier transform infrared spectroscopy for chemical analysis and X-ray fluorescence for detecting trace elements. Among the detected trace elements, Zn, Sr, Pb, Cu, Rb and Se, only the first three had significant values. Overall, the calcium components, namely calcium oxalate and calcium phosphate, were the most loaded by these elements contrary to organic components such as uric acid and cystine, which had low contents. The correlation of contents of Zn and Sr with the stone components (carbapatite, weddellite and whewellite) suggests an adsorption of these trace elements in the case of calcium stones rather than a catalytic process. 3.

    Medullary Sponge Kidney (MSK) is a benign disorder associated with renal stones in 60% of patients. Patients frequently have episodic painless hematuria but are otherwise asymptomatic unless renal calculi or infections complicate the disease. Nephrolithiasis is a relative, but frequently enforced, contraindication to space or other high performance flight. Two case reports of asymptomatic NASA flight crew with MSK and three cases of military aviators diagnosed with MSK are reviewed, all cases resulted in waiver and return to flight status after treatment and a vigorous follow up and prophylaxis protocol. MSK in aviation and space flight necessitates a highly case-by-case dependent evaluation and treatment process to rule out other potential confounding factors that might also contribute to stone formation and in order to re-qualify the aviator for flight duties.

    The effectiveness and side effects of ureteroscopic HoLL of ureteral stones should be evaluated. In 63 patients (17 female, 46 males) a total of 75 stones of 3-20 mm diameter were treated with ureteroscopic HoLL. 18.7 percent of stones were located in the proximal third, 24.0 percent in the middle third and 57.3 percent in the distal third of the ureter. HoLL was performed with small diameter semirigid and flexible ureteroscopes, 220 or 365 nm flexible laser fibers and a holmium:YAG laser at a power of 5-15 W (0.5-1.0 J, 10- 15 Hz). 47 of 63 patients (74.6 percent) were immediately free of stones, and 8 others (12.6 percent) lost their residual fragments spontaneously within two weeks. Another 2 patients received additional chmolitholysis for uric acid stone fragments, i.e. 90.5 percent of patients were stone free by one sitting of ureterscopic HoLL. Of the remaining 6 patients (9.5 percent) who still had residual calculi 4 weeks after HoLL, 2 asymptomatic patients refused any additional treatment, 2 patients preferred treatment with ESWL, and 2 patients had a successful second HoLL, thereby raising the success rate of ureteroscopic HoLL to 93.7 percent. 2 patients showed contrast medium extravasation on retrograde ureterograms, due to guide wire perforation. No ureteral stricture occurred. In conclusion, transurethral ureteroscopic HoLL proved to be a safe and successful minimal invasive treatment of ureteral calculi.

    One hundred and seven cystine-containing urinary calculi from 1 female and 101 male dogs were analyzed. Cystine-containing calculi accounted for 2% (107 of 5,375) of all canine urinary calculi submitted to the urinary stone analysis laboratory from July 1981 through December 1989. Male dogs that formed cystine calculi were compared with 3 other canine populations to determine whether certain breeds were apparently at increased or decreased risk for cystine calculus formation. In one or more of 3 population comparisons, significantly increased risk of cystine calculus formation was found in Mastiffs, Australian Cattle Dogs, English Bulldogs, Chihuahuas, Bullmastiffs, Newfoundlands, Dachshunds, Basenjis, Australian Shepherd Dogs, Scottish Deerhounds, Staffordshire Terriers, Miniature Pinschers, pitbull terriers, Welsh Corgis, Silky Terriers, and Bichon Frises. Significantly low risk of cystine calculus formation was found in German Shepherd Dogs, Poodles, Schnauzers, and mixed-breed dogs.

    Off-road motorcycling is one of the most popular sports activities practiced by millions of people in the world but little has been written on motocross traumatology and its prevention. This paper aims to evaluate motocross injuries in terms of injury ratio, location, causes, and possible prevention in a series of competitions organized by Motorcyclistic Federations over a 12-year period. We retrospectively evaluated 1,500 accidents with 1,870 rider injuries out of a group of 15,870 athletes participating in European off-road competition from 1980 to 1991. Data were collected from race medical reports, insurance declarations and follow-up forms filled up by riders involved in accidents. We then classified the type and location of the injury, modality of the accident, the protective gear used and the recovery of the riders. We compared our data to lesions noted in motorcycle road races using the chi-square test and the z-test. The overall incidence of motocross injuries in our study was 94.5 per thousand, while stadium cross competitions had a 150 per thousand rate and outdoor motocross a rate of 76 per thousand representing a risk of accident of 22.72 per thousand hours of riding. Among the total of 1,870 injuries, 1076 were bruises; 27.9% of these were in the upper extremities, 26.9% on the lower, 21.2% on the trunk, and 16% on the face. There were 450 fractures recorded, 50.9% in the upper extremities, 38% in the lower, and the rest were on the spine, chest, and skull. The 26 spine fractures (5.8%) produced permanent neurologic sequelae in eight patients. Ligamentous lesions accounted for 344 cases with 206 (59.9%) occurring in the lower extremities especially on the knee (42.4%). Head trauma was noted in 86 cases (5.7% of accidents) producing coma in 3%, and loss of consciousness in 14%. Limb involvement for all types of injuries were more frequent on the left side (60%). Motocross is a high-risk sport: our study revealed the most common modalities and types of

    PURPOSE: To determine the usefulness of reversed display of soft-copy abdominal radiographs for urinary calculi detection. MATERIAL AND METHODS: Sixty radiographs with a single urinary calculus less than 5 mm in the long diameter (15 in the kidney; 15 in the proximal ureter; 15 in the mid-ureter, 15 in the distal ureter) and 15 radiographs without calculi were evaluated. Four readers blinded to the presence or absence of urinary calculi on each radiograph reviewed the radiographs in the conventional display, reversed display, and combination of conventional and reversed displays at 1-week intervals. All images were evaluated in random order and the presence or absence of urinary calculi was interpreted using the confidence score from 1 to 5. RESULTS: Multireader analysis for calculi in all locations showed a greater area under the receiver operating curve for combination of the two displays (0.764) than for the conventional display alone (0.655) (P=0.031). In the single-reader analysis for calculi in all locations, the third reader showed a greater area under the receiver operating curve for the reversed display (0.784) than for the conventional display (0.622) (P=0.027). Multireader analysis of the calculi in the kidney showed a greater area under the receiver operating curve for combination of the two displays (0.824) than for the conventional display alone (0.703) (P=0.043). CONCLUSION: The reversed display of soft-copy abdominal radiographs may be useful for urinary calculi detection.

    To determine whether patients with proven ureteric calculi on IVU require repeat IVU after resolution of symptoms and passage of calculus on plain X-ray. IVU reports for a 12-month period were obtained and notes and X-rays of those patients with ureteric calculi were reviewed. Presentation, management and subsequent imaging after resolution of symptoms were determined for each patient. All X-rays were reviewed by a uroradiologist. Fifty-eight patients were investigated for the study. All initial IVUs showed upper tract dilation or obstruction. Forty-three eventually passed their calculi spontaneously and of these, 18 had KUB, all of which showed passage of the calculus and 25 had repeat IVU, 22 of which were normal. The 3 abnormal IVUs showed persisting calculi which were visible on the plain film. Fifteen patients required surgical intervention and all had repeat IVU, of which 5 were abnormal. This study suggests that following resolution of symptoms due to ureteric colic, patients who pass their calculi spontaneously can be followed up by KUB. Only those with persistent calculi on KUB or those who have had surgical intervention require repeat IVU.

    Thirty patients with partial or total staghorn stones or calculi larger than 30 mm were treated by piezoelectric lithotripsy (PEL) monotherapy using an EDAP LT-01 lithotripter with ultrasound guidance. Nineteen of these patients had pelvic stones; the other 11 had partial (9) or total (2) staghorn stones. All patients first underwent an initial lithotripsy session. No anesthesia or IV sedation was required in any case. If stone fragmentation was achieved during this first session, a double-J stent was inserted before the second lithotripsy session. Prior to the first session, 18 of 30 patients had sterile urine cultures; 12 of 30 presented major distension of the excretory tract. Results were analyzed to determine the factors influencing the outcome of this therapy. Three months after the first session, patients were considered cured if their stones had completely disappeared according to plain abdominal films (14 of 30, 46%). In seven patients (23.3%) fragmentation had occurred but residual fragments remained (1 to 3 fragments less than or equal to 4 mm). No fragmentation was obtained after the first session in nine patients (30.7%) (1 total staghorn stone, 8 pelvic stones). The mean number of treatment sessions was five (range, 1 to 15). Complications occurred in only 10% of patients (3 of 30): two steinstrassen and one acute pyelonephritis. Eighty-three percent of patients without major excretory tract distension and 55% of patients whose initial urine culture was sterile achieved a stone-free state. Therefore the best indications for PEL monotherapy for calculi larger than 30 mm are pelvic stones and partial staghorn stones and no major excretory tract dilatation in patients with sterile initial urine cultures.(ABSTRACT TRUNCATED AT 250 WORDS)

  10. Abortion in America: 12 years after Roe v. Wade.

    overturn the 7-to-2 Roe decision. In 1981, most abortions were obtained by young women, unmarried women, and white women. About 1.6 million abortions were reported for the US in 1981, representing about 26% of pregnancies that year. The US abortion rate remained essentially stable in 1981 and 1982 after rising each year between 1973 and 1980. The annual increases in the years just prior to 1980 were small. In 1981, as in 1980, 91% of abortions were performed at 12 or fewer weeks past the last menstrual period. Abortion services are most available, and rates are highest on the East and West coasts. 12 years after abortion was made legal in the US, the debate may get louder as prochoice activists launch efforts to match the campaign of the right-to-life movement.

    Full Text Available BACKGROUND Urinary calculus disease is one of the 3 most common urological diseases. It affects about 12% of the world population. Of all the urinary tract stones 20% are ureteral stones of which 70% are found in the lower third of ureter. Patients with ureteric calculi have wide range of complications which include acute pain necessitating hospitalization, urinary tract infection, anuria, acute renal failure, chronic renal failure, hydronephrosis, pyelonephritis and dehydration. The objective of the study is to study the effect of alpha adrenergic blockers in the passage of calculi in the lower third of the ureter compared to NSAIDs and oral fluids. MATERIALS AND METHODS The study included a total of 60 patients between the study period from Aug 2014 to Aug 2015. 30 patients were chosen randomly and advised to take plenty of oral fluids and treated with NSAID (diclofenac. The patients were then observed weekly and asked for any history of passage of calculi and ultrasound scan was repeated after 15 days to look for any passage of calculi. The findings were recorded and the patients are monitored and followed up for a period of one month. If the stone was passed successfully, it was confirmed with ultrasonography. After 1 month if treatment failed, conservative management was discontinued and advised surgery. RESULTS Majority of the patients were in the age group 20-40 yrs. The mean size of the calculi was 6.62 cms on the right side and 6.0 cms on left side. Out of the 30 patients who were on alpha 1 blocker 22 patients had passed calculi and 8 patients had no results with 73 % success rate. In 30 patients who were not on alpha adrenergic blockers 7 passed out the calculi and 23 did not pass the calculi. 5 among the 23 underwent urethrorenoscopy (URS. CONCLUSION Alpha adrenergic blockers is an effective and safe drug in the management of calculi in the lower third of the ureter. Most patients with ureteric calculi were rendered stone free with

    This case report describes the successful treatment of a severe chronic periodontitis case by nonsurgical therapy and a strict maintenance program over a 12-year period. A 38-year-old man concerned about the protrusion of his maxillary incisors was referred for periodontal treatment. The teeth in the maxillary arch had generalized severe chronic periodontitis. Several treatment options were presented to the patient including the most aggressive, extraction of all maxillary teeth, and the most conservative, scaling and root planing. The patient opted to having the most conservative approach, even though the prognoses for the maxillary teeth were unfavorable. Therefore, he received nonsurgical therapy via scaling and root planing combined with systemic antibiotics before referral to an orthodontist to address the esthetic concerns. The maxillary dentition was treated with orthodontic therapy to retract and align the maxillary anterior segment. Periodontal maintenance (1-hour session), including subgingival instrumentation, was performed 4 times per year until the end of the 12-year follow-up period. The patient only missed 2 appointments in 12 years. Twelve years later, the results revealed that all but 1 maxillary tooth were maintained in a state of acceptable health, function, and esthetics. Although most would agree with the initial poor prognosis of this patient's case, nonsurgical periodontal therapy was utilized with a 3-month periodontal maintenance program and demonstrated long-term success. The outcome presented in this case report may only have been possible because of patient compliance, professional experience, skill, and supervision throughout the course of treatment.

    Full Text Available ABSTRACT   Introduction: Basic Health Research 2013 showed Dental Caries Index in school age student in West Java was lower than the expected target, with occlusal surface as most affected part. The purpose of this study was to determine the risk status of dental caries in school age student by using cariogram analysis. Methods: Observational research. Study was conducted on 30 student aged 11-12 years with caries high risk on occlusal surfaces. Purposive sampling was taken from students of SDN Cikawari and SDN Mekarjaya Bandung Regency with high DMF-S index. Inclusion criteria: male and female, aged 11-12 years, good systemic health, SDN Mekarjaya and SDN Cikawari Bandung Regency students. Exclusion criteria: suffering from systemic disorder, currently in long-term antibiotic therapy, orthodontic appliance usage. Case history, eating habits and intake of fluoride, caries experience, salivary volume and buffering capacity of each sample was examined using cariogram examination method. Results: The cariogram analysis showed 43% chance of caries avoidance. Diet control was 23.3%, includes two factors: sugary foods and eating frequency. Bacteria control was 11.9% by evaluating both bacterial factors (the amount of plaque and the bacteria Streptococcus mutans. Vulnerability control was 14.4%, including caries prevention by the continuation of fluorine program and other conditions control that affect salivary secretions. Conclusion: Based on cariogram analysis found that all samples who had occlusal surfaces caries were at a high risk category, but still having moderate potential of avoiding new caries occurrence by controlling risk factors.

    2004-12-01

    Full Text Available Abstract Background Micro computed tomography (micro CT has been shown to provide exceptionally high quality imaging of the fine structural detail within urinary calculi. We tested the idea that micro CT might also be used to identify the mineral composition of urinary stones non-destructively. Methods Micro CT x-ray attenuation values were measured for mineral that was positively identified by infrared microspectroscopy (FT-IR. To do this, human urinary stones were sectioned with a diamond wire saw. The cut surface was explored by FT-IR and regions of pure mineral were evaluated by micro CT to correlate x-ray attenuation values with mineral content. Additionally, intact stones were imaged with micro CT to visualize internal morphology and map the distribution of specific mineral components in 3-D. Results Micro CT images taken just beneath the cut surface of urinary stones showed excellent resolution of structural detail that could be correlated with structure visible in the optical image mode of FT-IR. Regions of pure mineral were not difficult to find by FT-IR for most stones and such regions could be localized on micro CT images of the cut surface. This was not true, however, for two brushite stones tested; in these, brushite was closely intermixed with calcium oxalate. Micro CT x-ray attenuation values were collected for six minerals that could be found in regions that appeared to be pure, including uric acid (3515 – 4995 micro CT attenuation units, AU, struvite (7242 – 7969 AU, cystine (8619 – 9921 AU, calcium oxalate dihydrate (13815 – 15797 AU, calcium oxalate monohydrate (16297 – 18449 AU, and hydroxyapatite (21144 – 23121 AU. These AU values did not overlap. Analysis of intact stones showed excellent resolution of structural detail and could discriminate multiple mineral types within heterogeneous stones. Conclusions Micro CT gives excellent structural detail of urinary stones, and these results demonstrate the feasibility

    Full Text Available BACKGROUND: People with schizophrenia have been demonstrated to have higher overall morbidity and all-cause mortality rates from general medical conditions. However, little attention has been given to the urinary system of people with schizophrenia. As no direct evidence has been reported demonstrating a link between schizophrenia and urinary calculi, this study utilized a population-based case-control study design to investigate the possibility of an association between schizophrenia and the occurrence of urinary calculi. METHOD: This study used data from the Taiwan Longitudinal Health Insurance Database. Cases consisted of 53,965 urinary calculi patients newly diagnosed between 2002 and 2008. In total, 269,825 controls were randomly selected and matched with the cases in terms of age and sex. Each person was traced to discern whether he had previously received a diagnosis of schizophrenia. Conditional logistic regression models were performed for the analysis. RESULTS: A total of 3,119 (1.0% subjects had been diagnosed with schizophrenia prior to the index date. This included 0.7% of the patients with urinary calculi, and 1.0% of the controls. A prior diagnosis of schizophrenia was independently associated with a 30% decrease (95% CI = 0.62-0.76 in the occurrence of urinary calculi. The reduction was even more remarkable in males (38%, 95% CI = 0.55-0.71 and in elder individuals independent of gender (48% in those aged >69, 95% CI = 0.36-0.77. CONCLUSION: Our findings suggest that there is an inverse association between schizophrenia and urinary calculi. Future studies are needed to elucidate the mechanisms by which schizophrenia negatively associates with urinary calculi.

    2007-08-01

    To determine the prevalence of renal calculi in patients treated with zonisamide during randomized, controlled and open-label clinical trials, and from post-marketing surveillance data. Reports of renal calculi from four placebo-controlled double-blind trials of zonisamide, their long-term open-label treatment extension phases, and the US/European zonisamide clinical trial programme were reviewed. One double-blind study and its extension included routine ultrasound screening to identify asymptomatic calculi. Post-marketing surveillance data were also investigated, as was concomitant treatment with topiramate. No symptomatic renal calculi were reported during four randomized double-blind, placebo-controlled trials involving 848 subjects (including 498 zonisamide recipients) treated for up to 3 months. In long-term extension studies with treatment for up to 24 months, symptomatic renal calculi were reported in 9/626 (1.4%) patients. Pooled safety data from all US/European clinical trials identified 15/1296 (1.2%) patients with symptomatic renal calculi during treatment for up to 8.7 years. Post-marketing surveillance revealed nine cases from 59 667 patient-years of exposure in the USA, and 14 from 709 294 patient-years of exposure in Japan; only one case occurred during concomitant topiramate and zonisamide treatment. No imbalance in electrolyte levels was found from 35 patients receiving such co-treatment in clinical trials. The available data suggest that the risk of developing renal calculi during zonisamide treatment is low. Data are insufficient to determine whether concomitant treatment with topiramate increases the risk of renal stones.

    The incidence of urinary stones in Danish children is unknown. An estimate from The National Diagnosis Registry in Denmark is approximately 1:13,500. The purpose was to estimate the incidence of urinary stones and their composition in children in relation to sex, age and family history. A retrospective review of all children presented at Aarhus University Hospital, Skejby, or Roskilde Hospital from October 1999 through October 2005 with urinary tract calculi. 42 patients with an average age of 7.9 years. The sex ratio was 1.7 boys to 1 girl. 7 were of an ethnic origin other than Danish. 12, all boys, had inborn urogenital tract malformation. Two had secondary malformation and one had inborn error of metabolism. The incidence of urogenital infection was higher in children with malformation. In 26 patients, stone analysis and composition were available. 54% of the stones had a calcium component. One third of the children had a family history of urolithiasis. Urinary tract stone is a rather difficult pediatric diagnosis. The most frequent symptom is abdominal pain. Ultrasound established the diagnosis in 50% of cases. All concrements were diagnosed with excretory urogram or computerized tomography. 30% of the children had a family history of urolithiasis. This confirms the importance of metabolic screening and stone analysis in children.

    Full Text Available Extracorporeal Shock Wave Lithotripsy (ESWL is still the treatment of choice for most renal and upper ureteric stones; however the outcome depends on multiple factors. The objective of this study was to investigate the effects of stone density, as measured by Hounsfield Units (H.U by non-contrast Computerized Tomography (CT, stone size and stone location on ESWL treatment outcome of urinary calculi in Jordanian patients. 65 patients underwent clinical, biochemical and radiological assessments followed by ESWL treatment. Statistical analyses including chi-square, analysis of variance (ANOVA, correlation, regression were performed for statistical significance between ESWL treatment, stone fragmentation and stone density, size and location in the renal pelvis. ESWL success rate was high (94% for low density stones (< 500 Hounsfield units. In general CT densities of 750 Hounsfield units or less were almost always successfully treated by ESWL. An inverse association between ESWL treatment outcome and stone size was also documented. CT stone density and stone size combined account for nearly 73% of the variation in the number of shock waves required to attain fragmentation. Stones located in lower calyceal area had less success rates. In conclusion, stones with higher density, large size and lower location may better be managed by percutaneous nephrolithotomy.

    To determine the impact of staghorn calculi branch number on outcomes of percutaneous nephrolithotomy (PNL). Retrospectively, we evaluated 371 patients (386 renal units) who underwent PNL for staghorn calculi. All calculi were showed with CT three-dimensional reconstruction (3DR) imaging preoperatively. From 3DR images, the number of stone branching into minor renal calices was recorded. According to the number, patients were divided into four groups. Group 1: the branch number 2-4; Group 2: the branch number 5-7; Group 3: the branch number 8-10; Group 4: the branch number >10. The number of percutaneous tract, operative time, staged PNL, intraoperative blood loss, postoperative hospital stay, complications, main stone composition, and stone clearance rate were compared. A significantly higher ratio of multitract (pPNL (pPNL for calculi with a stone branch number ≥5. There was no statistical difference in intraoperative blood loss (p=0.101) and main stone composition (p=0.546). There was no statistically meaningful difference among the four groups based on the Clavien complication system (p=0.46). With the stone branch number more than five, the possibility of multitract and staged PNL, lower rate of stone clearance, and a longer postoperative hospital stay increases for staghorn calculi.

    Purpose: Renal calculi are common extracolonic incidental findings on computed tomographic colonography (CTC). This work aims to develop a fully automated computer-aided diagnosis system to accurately detect renal calculi on CTC images. Methods: The authors developed a total variation (TV) flow method to reduce image noise within the kidneys while maintaining the characteristic appearance of renal calculi. Maximally stable extremal region (MSER) features were then calculated to robustly identify calculi candidates. Finally, the authors computed texture and shape features that were imported to support vector machines for calculus classification. The method was validated on a dataset of 192 patients and compared to a baseline approach that detects calculi by thresholding. The authors also compared their method with the detection approaches using anisotropic diffusion and nonsmoothing. Results: At a false positive rate of 8 per patient, the sensitivities of the new method and the baseline thresholding approach were 69% and 35% (p < 1e − 3) on all calculi from 1 to 433 mm{sup 3} in the testing dataset. The sensitivities of the detection methods using anisotropic diffusion and nonsmoothing were 36% and 0%, respectively. The sensitivity of the new method increased to 90% if only larger and more clinically relevant calculi were considered. Conclusions: Experimental results demonstrated that TV-flow and MSER features are efficient means to robustly and accurately detect renal calculi on low-dose, high noise CTC images. Thus, the proposed method can potentially improve diagnosis.

    Full Text Available The surgical management of pediatric upper urinary tract calculi has evolved from open surgery to minimally invasive techniques. With advancement in instrumentation, endourological procedures are being performed more commonly in children. However, the endourological management of renal and ureteral stones in the pediatric population is considered challenging, owing to the smaller size of the urinary tract. Various minimally invasive techniques that are being applied in the management of pediatric urolithiasis, include shock wave lithitripsy (SWL, percutaneous nephrolithotomy (PCNL, ureterorenoscopy and a combination of these procedures. The role of SWL is well established and is considered the first line of treatment in the management of urinary calculi in pediatric patients. Recent reports have confirmed the safety of PCNL and ureteroscopy in children, although they are not as widely practiced in children as in adults. This article reviews literature published till October 2005, pertaining to the minimally invasive management of pediatric upper urinary tract calculi.

    Full Text Available Flexible retrograde ureteroscope is now being widely used in endoscopic management of the urinary calculi. We report technique of supine ante grade flexible ureteroscopy in treating impacted upper and mid ureteric calculi in a pediatric patient. A six year-old boy with a history of acute right ureteric colic was investigated and found to have right upper and middle impacted ureteric calculi. He was planned for ureteroscopy, but the intramural part of the ureter could not be dilated. Hence, a decision was taken to do an antegrade flexible ureteroscopy in the supine position. An antegrade renal access was established in the supine position using ultrasound- guided puncture, a 22 Fr Amplatz was placed after serial dilatation of the tract and the stones were accessed using a flexible ureteroscope. The stones were then disintegrated using holmium laser. The ureter was stented at the end of the procedure. IVU done after six months revealed normal right kidney.

    Classification of differential forms on κ-Minkowski space, particularly, the classification of all bicovariant differential calculi of classical dimension is presented. By imposing super-Jacobi identities we derive all possible differential algebras compatible with the κ-Minkowski algebra for time-like, space-like and light-like deformations. Embedding into the super-Heisenberg algebra is constructed using non-commutative (NC) coordinates and one-forms. Particularly, a class of differential calculi with an undeformed exterior derivative and one-forms is considered. Corresponding NC differential calculi are elaborated. Related class of new Drinfeld twists is proposed. It contains twist leading to κ-Poincaré Hopf algebra for light-like deformation. Corresponding super-algebra and deformed super-Hopf algebras, as well as the symmetries of differential algebras are presented and elaborated. Using the NC differential calculus, we analyze NC field theory, modified dispersion relations, and discuss further physical applications.

    Full Text Available Background The study of ancient microorganisms in mineralized dental plaque or calculi is providing insights into microbial evolution, as well as lifestyles and disease states of extinct cultures; yet, little is still known about the oral microbial community structure and function of pre-Columbian Caribbean cultures. In the present study, we investigated the dental calculi microbiome and predicted function of one of these cultures, known as the Saladoid. The Saladoids were horticulturalists that emphasized root-crop production. Fruits, as well as small marine and terrestrial animals were also part of the Saladoid diet. Methods Dental calculi samples were recovered from the archaeological site of Sorcé, in the municipal island of Vieques, Puerto Rico, characterized using 16S rRNA gene high-throughput sequencing, and compared to the microbiome of previously characterized coprolites of the same culture, as well modern plaque, saliva and stool microbiomes available from the Human Microbiome Project. Results Actinobacteria, Proteobacteria and Firmicutes comprised the majority of the Saladoid dental calculi microbiome. The Saladoid dental calculi microbiome was distinct when compared to those of modern saliva and dental plaque, but showed the presence of common inhabitants of modern oral cavities including Streptococcus sp., Veillonella dispar and Rothia mucilaginosa. Cell motility, signal transduction and biosynthesis of other secondary metabolites may be unique features of the Saladoid microbiome. Discussion Results suggest that the Saladoid dental calculi microbiome structure and function may possibly reflect a horticulturalist lifestyle and distinct dietary habits. Results also open the opportunity to further elucidate oral disease states in extinct Caribbean cultures and extinct indigenous cultures with similar lifestyles.

    The study of ancient microorganisms in mineralized dental plaque or calculi is providing insights into microbial evolution, as well as lifestyles and disease states of extinct cultures; yet, little is still known about the oral microbial community structure and function of pre-Columbian Caribbean cultures. In the present study, we investigated the dental calculi microbiome and predicted function of one of these cultures, known as the Saladoid. The Saladoids were horticulturalists that emphasized root-crop production. Fruits, as well as small marine and terrestrial animals were also part of the Saladoid diet. Dental calculi samples were recovered from the archaeological site of Sorcé, in the municipal island of Vieques, Puerto Rico, characterized using 16S rRNA gene high-throughput sequencing, and compared to the microbiome of previously characterized coprolites of the same culture, as well modern plaque, saliva and stool microbiomes available from the Human Microbiome Project. Actinobacteria, Proteobacteria and Firmicutes comprised the majority of the Saladoid dental calculi microbiome. The Saladoid dental calculi microbiome was distinct when compared to those of modern saliva and dental plaque, but showed the presence of common inhabitants of modern oral cavities including Streptococcus sp., Veillonella dispar and Rothia mucilaginosa. Cell motility, signal transduction and biosynthesis of other secondary metabolites may be unique features of the Saladoid microbiome. Results suggest that the Saladoid dental calculi microbiome structure and function may possibly reflect a horticulturalist lifestyle and distinct dietary habits. Results also open the opportunity to further elucidate oral disease states in extinct Caribbean cultures and extinct indigenous cultures with similar lifestyles.

The diagnosis is often missed at intravenous urography (IVU and US because the ipsilateral ureter and kidney are grossly normal. In this case the diagnosis was established with ultrasound (US and mainly with multidetector computerized tomography (MDCT imaging using multiplanar reformats and 3-D reconstructions which were unique to this case. MDCT scans not only revealed the exact diagnosis and anatomic relationships but also ruled out other pathologies included in the differential diagnosis as well, such as ureter and bladder diverticula.

    Few Western studies have focused on percutaneous techniques using percutaneous transhepatic choledochoscopy (PTHC) and holmium:yttrium-aluminum-garnet (YAG) laser to ablate biliary calculi in patients unable or unwilling to undergo endoscopic or surgical removal of the calculi. The authors report the efficacy of the holmium:YAG laser in clearing complex biliary calculi using percutaneous access techniques. This study retrospectively reviewed 13 non-Asian patients with complex secondary biliary calculi treated percutaneously using holmium:YAG laser. Percutaneous access was accomplished via left, right, or bilateral hepatic ducts and upsized for passage of a 7-Fr video choledochoscope. Lithotripsy was performed under choledochoscopic vision using a holmium:YAG laser with 200- or 365-microm fibers generating 0.6 to 1.0 joules at 8 to 15 Hz. Patients underwent treatment until stone clearance was confirmed by PTHC. Downsizing and subsequent removal of percutaneous catheters completed the treatment course. Seven men and six women with an average age of 69 years underwent treatment. All the patients had their biliary tract stones cleared successfully. Of the 13 patients, 3 were treated solely as outpatients. The average length of percutaneous access was 108 days. At this writing, one patient still has a catheter in place. The average number of holmium:YAG laser treatments required for stone clearance was 1.6, with no patients requiring more than 3 treatments. Of the 13 patients, 8 underwent a single holmium:YAG laser treatment to clear their calculi. Prior unsuccessful attempts at endoscopic removal of the calculi had been experienced by 7 of the 13 patients. Five patients underwent percutaneous access and subsequent stone removal as their sole therapy for biliary stones. Five patients were cleared of their calculi after percutaneous laser ablation of large stones and percutaneous basket retrieval of the remaining stone fragments. There was one complication of pain

    Full Text Available Standard treatment modalities of caliceal diverticular calculi range from extracorporal shockwave lithotripsy (SWL over retrograde intrarenal surgery (RIRS, percutaneous nephrolithotomy (PNL and laparoscopic stone removal. A 55-year-old woman presented with a history of pyelonephritis based on a caliceal diverticular calculus. Due to the narrow infundibulum and anterior location, a robot-assisted laparoscopic calicotomy with extraction of the calculi and fulguration of the diverticulum was performed, with no specific perioperative problems and good stone-free results. This article shows technical feasibility with minimal morbidity of robot-assisted laparoscopic stone removal and obliteration of a caliceal diverticulum.

    Full Text Available Background and Objectives: The group of 6-12 year-old students are the main target of oral health programs due to the high prevalence of dental caries and the formation of permanent teeth during this age and the lifestyle-shaping nature of the period. Schools provide the easiest and most effective means of accessing this group. The present study was conducted to examine the impact of school-based interventions on improved oral health in 6-12 year-old students. Materials and Methods: The present systematic review searched for its English and Persian keywords in databases such as the Scopus, Proquest, Science Direct, Pubmed, Springer, Biomed Central, Google Scholar, IranMedex and SID and examined studies published between January 2004 and September 2014 about educational interventions aiming to prevent oral diseases and promote associated health behaviors in students. Results: The 17 studies selected for examination were divided into two categories: first, assessing an education based on self-care behaviors and preventive services second, assessing an education based on self-care behaviors only. Those interventions that were consistent in nature, involved the parents and the school personnel, used behavior change models, used a combination of several training methods, used practical experiences and provided preventive services were more effective in promoting knowledge and health behaviors and reducing dental caries and plaque in this group of children. Conclusion: Providing consistent community-based education, using a combination of several organized educational programs, following up on the children's progress, using behavior change theories and models and providing prevention services are the most effective measures for achieving the desired goals.

    The frequent and high consumption of sugar products, particularly sucrose, is one of the causative factors of dental caries. Meta-analyses assessing the relationship between sugar intake and dental caries revealed that a restricted sugar intake to less than 10% of the daily energy intake results in substantial health benefits. Sugar consumption in Poland is 2-fold higher than recommended by the WHO. As change in dietary habits is slow, knowledge of whether a gradual reduction of sugar consumption influences beneficially the dental condition is important. Assessment of the relationship between caries experience and sugar consumption in 12-year-old children. The data obtained from the Statistical Agricultural Yearbooks of the Central Statistical Office in Poland regarding the average yearly sugar intake by a person in the years 1995-2013, and caries prevalence (frequency and DMFT) resulting from the national epidemiological studies of the 12-year-old children conducted by the Ministry of Health in those years were analyzed. The data was analyzed by linear regression. Regression function parameters and coefficients of determination were assessed for a possible link between sugar consumption and dental caries frequency and severity was expressed as DMFT value. The mean yearly sugar intake by a statistical Pole ranged from 43.6 kg (2002) to 35.3 kg (2006). Despite a slight trend to lower the sugar consumption, its mean intake in 1995 and 2013 was the same (41.9 kg). Caries frequency and DMFT decreased in 2012 compared to 1995 from 90.5% to 79.6% and from 4.3 to 3.53 kg in 2012, respectively. The increased sugar intake by 1 kg/year caused the increase of caries frequency by 1% and DMFT value by 0.2. Even a relatively low decrease in sugar consumption can exert some beneficial influence on the dental condition in adolescents, particularly upon the severity of caries.

    To evaluate the development, safety and efficacy of percutaneous nephrolithotomy(PNL) for management of upper urinary tract calculi in pediatric patients. In the study, 77 pediatric patients undergoing 87 PNLs through mini or standard tract for upper urinary tract calculi between January 2005 and December 2016 in Peking University People's hospital were reviewed, including 69 renal calculi, 6 upper ureteral calculi, 12 renal and upper ureteral calculi, 35 single calculi, 43 multiple calculi and 9 staghorn calculi. The development and efficacy of PNL in pediatric patients were studied by analyzing the characteristics and clinical indexes, and by reviewing the associated literature. The Clavien classification system was used to evaluate the complications after PNL. A total of 87 PNLs were performed in 77 pediatric patients. Eighty-one upper urinary tract calculi were managed through a single tract(93.1%), 5 pediatric patients were managed through 2 tracts(5.7%), and 1 pediatric patient was managed through 3 tracts(1.2%). The mean operating time was (77.0±29.8) min. The stone-free rate after one session was 100% for single calculi and 71.2% for multiple or staghorn calculi, 5(5.8%) children underwent auxiliary procedure to remove the residual calculi and the final stone-free rate of PNL was 88.5%. One of the main complications of pediatric PNL was fever. Sixteen (18.4%) had moderate fever(38-39 °C), 5 (5.7%) had high fever (39-40 °C) and there were no severe complications of infection, such as sepsis or septic shock. The mean hemoglobin loss was (10.3±16.1) g/L and the serum creatinine rise was (7.0±13.3) μmol/L. One(1.2%) pediatric patient suffered ureteroscopic lithotripsy because of the obstruction by the residual stone in ureter. No injury of organs or retroperitoneal urinary extravasation occurred. General assessment of the complications showed Clavien grade I complications in 14 (16.1%) pediatric patients, grade II in 7(8.0%) children and grade III in 1

    ABSTRACT Objective: To report our experience of minimally invasive percutaneous nephrolithotomy(MPCNL) in managing upper urinary tract calculi complicated with severe spinal deformity. Materials and Methods: Between August 2001 to December 2012, 16 upper urinary calculi in 13 patients with severe spinal deformity were treated by MPCNL. Preoperative investigation of the respiratory function, evaluation of anatomy by intravenous urography (IVU) and CT scan, and preoperative kidney ultrasonagraphy with simulation of the percutaneous puncture were performed in all patients. The percutaneous puncture was guided by ultrasonography. Results: A total of 19 MPCNL procedures were performed in 16 kidneys, with an average 1.2 procedures in each kidney. Three kidneys needed two sessions of MPCNL, and 2 kidneys needed combined treatment with retrograde flexible ureterscopic lithotripsy. All procedures were successfully completed with no major complications during or after surgery. The mean (range) operative duration was 67 (20-150) min and the mean postoperative haemoglobin drop was 1.0 (0.2-3.1) g/dL. Complete stone-free status was achieved in 14 kidneys. At a mean follow-up of 48(3-86) months, recurrence of small lower calyx stone was detected in one patient. Recurrent UTI was documented by urine culture in two patients and managed with sensitive antibiotics. Conclusion: PCNL for patients with severe spinal deformities is challenging. Ultrasonography-assisted puncture can allow safe and successfully establishment of PCN tract through a narrow safety margin of puncture and avoid the injury to the adjacent organs. However, the operation should be performed in tertiary centers with significant expertise in managing complex urolithiasis. PMID:27509373

  6. Renal papillary calcification and the development of calcium oxalate monohydrate papillary renal calculi: a case series study

    Science.gov (United States)

    2013-01-01

    Background The objective of this study is to determine in a case series (four patients) how calcified deposits in renal papillae are associated with the development of calcium oxalate monohydrate (COM) papillary calculi. Methods From the recently collected papillary calculi, we evaluated retrospectively patients, subjected to retrograde ureteroscopy, with COM papillary lithiasis. Results The COM papillary calculi were found to result from subepithelial injury. Many of these lesions underwent calcification by hydroxyapatite (HAP), with calculus morphology and the amount of HAP in the concave zone dependent on the location of the calcified injury. Most of these HAP deposits grew, eroding the epithelium covering the renal papillae, coming into contact with urine and starting the development of COM calculi. Subepithelial HAP plaques may alter the epithelium covering the papillae, resulting in the deposit of COM crystals directly onto the epithelium. Tissue calcification depends on a pre-existing injury, the continuation of this process is due to modulators and/or crystallization inhibitors deficiency. Conclusions Since calculus morphology and the amount of detected HAP are dependent on the location and widespread of calcified injury, all types of papillary COM calculi can be found in the same patient. All patients had subepithelial calcifications, with fewer papillary calculi, demonstrating that some subepithelial calcifications did not further evolve and were reabsorbed. A high number of subepithelial calcifications increases the likelihood that some will be transformed into COM papillary calculi. PMID:23497010

    This work shows the study performance to intestinal enterolithis from a 91 year old patient with multiple enterolithiasis confirmed by abdominal X-ray and TAC analyses showing the presence of intestinal, renal and bile stones. This enterolithis is associated with colon adenocarcinoma. The enteroliths were obtained by hemicolectomia and were analyzed by infrared spectroscopy (IR), giving non-stoichiometry carbonate apatite whitloquite-like with, possibly, organic material. By atomic emission spectroscopy we found Ca, Mg, K, Na and K (mg/100 mg of calculi) and Zn, Ba, Mn, Fe, Cu, Si, Ti and Br in minor proportion (microg/100 mg of calculi). Because of calculi morphology and the IR spectra (non-stoichiometry carbonate apatite) we carried out analysis by high performance liquid chromatography (HPLC) and found coproporphyrin (about microg/g of calculi) and uroporphyrin, protoporphyrin and heptacarboxy-porphyrin in minor extent. Calculi were also studied by scanning electronic microscopy and EDX and X-ray diffraction giving crystals of CaP4O11. All these results show that intestinal enteroliths composition are similar to renal calculi although its morphology differs from renal calculi.

    Full Text Available Background: Urolithiasis, usually affecting people in the prime of life, causes significant morbidity and loss of productivity. Uretericstones account for 2/3rd of all urinary calculi brought to attention of doctors. The damaging effects of the calculi may result in obstruction with dilatation of the urinary tract, leading to stasis and severe infection. Aims and Objectives: To evaluate patients with urinary stones with regards to the incidence, age, sex,clinical presentation, site, size, side, management and their complications. Material and Methods:It was a prospective study carried out by Department of Surgery at Annasaheb Chudaman Patil Memorial Medical College, and Hospital Dhule for a period of two years. Patients were selected after they were diagnosed as having ureteric calculi. The patients were treated by conservative or surgical methods, and the outcome was monitored. Statistical analysis of the data was done for obtaining results.Result: The majority of the patients were males with peak age group in the second and third decade. Pain in abdomen or loin tenderness was the most common presenting symptom. Most of the patients were treated by conservative medical management. Endourological procedures were the most commonly performed surgical intervention. Conclusion: Most of the patients with ureteric calculi present with painin abdomen and majority can be treated by medical management. With the availability of better facilities the requirement for open surgery is decreasing and endourological procedures are becoming the means of surgical intervention.Complications are minimal with surgical expertise for endourological procedures.

    The aim of our study was to compare non-contrast spiral CT, US and intravenous urography (IVU) in the evaluation of patients with renal colic for the diagnosis of ureteral calculi. During a period of 17 months, 112 patients with renal colic were examined with spiral CT, US and IVU. Fifteen patients were lost to follow-up and excluded. The remaining 97 patients were defined to be either true positive or negative for ureterolithiasis based on the follow-up data. Sensitivity, specificity, positive and negative predictive value and accuracy of spiral CT, US and IVU were determined, and secondary signs of ureteral stones and other pathologies causing renal colic detected with these modalities were noted. Of 97 patients, 64 were confirmed to have ureteral calculi based on stone recovery or urological interventions. Thirty-three patients were proved not to have ureteral calculi based on failure to recover a stone and diagnoses unrelated to ureterolithiasis. Spiral CT was found to be the best modality for depicting ureteral stones with a sensitivity of 94 % and a specificity of 97 %. For US and IVU, these figures were 19, 97, 52, and 94 %, respectively. Spiral CT is superior to US and IVU in the demonstration of ureteral calculi in patients with renal colic, but because of its high cost, higher radiation dose and high workload, it should be reserved for cases where US and IVU do not show the cause of symptoms.

    Conclusion: Both OSS and PNL are viable options for the management of staghorn stones. Considering the lower postoperative complication rate and need for auxiliary treatment, we suggest that OSS is more suitable for staghorn stones with large burdens. OSS should still be considered as a valid treatment for patients with complex staghorn calculi, although PNL is a less invasive treatment option in most cases.

    2017-04-01

    During the past 12 years, we have been engaging secondary level science students (15 to 18 years old) in the extracurricular activities of our school's Earth and Space Sciences Club, providing them with some of the skills needed to excel in science, technology, engineering, arts, and mathematics (STEAM). Our approach includes the use of authentic scientific data, project based learning, and inquiry-centred activities that go beyond the models and theories present in secondary level textbooks. Moreover, the activities and projects carried out, being eminently practical, also function as an extension of the curriculum and frequently enable the demonstration of the applicability of several concepts taught in the classroom in real life situations. The tasks carried out during these activities and research projects often require the combination of two or more subjects, promoting an interdisciplinary approach to learning. Outside of the traditional classroom settings, through interdisciplinary explorations, students also gain hands-on experience doing real science. Thereby, during this time, we have been able to promote meaningful and lasting experiences and spark students' interest in a wide diversity of topics.

    This thesis work is about the validation of the new criticality-safety package CRISTAL and contributes to the modernization and the improvement of the computational tools. The first part presents neutronic elements, the objectives of safety criticality studies and the package CRISTAL. Then, the validation work concerned two series of experiments involving uranyl solutions (UO{sub 2}F{sub 2}) and UO{sub 2} powders. For these experiments, the differences between the computation results and the experimental results were analysed. It was highlighted interesting physical phenomena such of the compensations of errors between the approximate representation by the 99 energy group structure on the first resonance of oxygen and the anisotropy of the diffusion simulation as well as the influence of uranium 234 in high enriched solutions in uranium 235. Once the work of the experimental qualification carried out, raises the question of the use the base of qualification and the ''calculation-experiment'' variations which are referred to it. It is often difficult to establish the link between the ''studied configuration'' and the experiments of the base of qualification. The presented characterisation system proposes to answer in a way automatic and quantified this difficulty: - in bringing an answer on the package qualification for the studied configuration, - in giving an estimate of the package bias. To answer these points, it was defined a set of 35 characteristic neutronic parameters representing the behaviour of the medium. To process the information brought by these parameters and to use it to answer the objectives of the system, we called upon statistical methods (Principal Components Analysis and Sliced Inverse Regression). The results obtained in the feasibility studies showed the relevance of these methods for the considered objectives. (author)

    Tubeless percutaneous nephrolithotomy (PNL) remains a challenging technique for the surgical treatment of staghorn renal calculi. Our study was designed to compare surgical outcomes between conventional and tubeless PNL. We retrospectively enrolled consecutive patients who underwent conventional or tubeless PNL under general anesthesia performed by a single surgeon (H.J.) for the treatment of staghorn calculi between 2003 and 2012. All patients were divided into two groups: group 1 included patients who underwent conventional PNL and group 2 included patients who were managed by tubeless PNL for the treatment of staghorn calculi. Preoperative and postoperative parameters were analyzed between the two groups, including age, stone burden, complications, any interventions, and duration of hospital stay. A total of 165 patients (group 1, 106; group 2, 59) were enrolled in the study. No significant differences in age, sex, body mass index, or stone laterality were observed between the two groups. The mean stone burdens (±standard deviation) of group 1 and group 2 were 633.6 (±667.4) and 529.9 (±362.8), respectively (p=0.271). The postoperative stone-free clearance rate was higher in group 2 (78.0%) than in group 1 (69.8%); however, the difference was not clinically significant (p=0.127). In addition, no significant differences in postoperative complications, including fever, bleeding, infection, or additional interventions, were observed between the two groups. Our results demonstrated that tubeless PNL has the same effectiveness and safety as conventional PNL in the treatment of staghorn calculi. Tubeless PNL may be feasible for managing renal staghorn calculi.

  16. [Computer-assisted total knee arthroplasty: 12 years experience in Grenoble].

    Computer-assisted total knee arthroplasty was developed in Grenoble in the mid-1990s. The first human implantation was performed on 21 January 1997, with no particular problems. Since this date more than 200,000 patients have been implanted with our device all over the world. The device is passive (not active like a robot), and requires no pre- or perioperative imaging. It is based on kinematics and palpation, the surgeon remaining in charge at all times. The computer helps to identify the lower leg axis, to accurately fix the bone cutting guides, and to check the ligament balance. These steps are not easy to perform with conventional ancillaries. The effectiveness of computer-assisted total knee replacement is well documented, although it is too early to claim that a "well-aligned" prothesis will have a better survival rate. Long-term follow-up studies are needed, with modern prostheses, to confirm the results of historical studies.

    Full Text Available Background: Congenital lobar emphysema (CLE is characterised by over distension of one lobe and pressure on the adjacent lobe and mediastinum. In this study, we review the pathological results of our paediatric patients with CLE, highlighting the early and late complications that occurred in these patients. Patients and Methods: In a prospective study from 1996 to 2008, we evaluated 30 patients with CLE diagnosis. Variables collected included sex, age at the time of diagnosis, radiological diagnostic method, type of treatment, pathological analysis, surgical findings and early postoperative complications. Parents were asked to refer to our clinic for follow-up and evaluation of late complications. Results: Thirty patients and males accounted for majority of the study population (n = 20, 67%. The mean age of male and female patients (at admission was 7.2 ± 2.3 and 4.7 ± 1.2 months respectively (P = not significant. The main diagnostic method was chest x-ray (CXR in all patients. Abnormal bronchial cartilage was found in 71% of patients. The most affected lobe was left upper lobe (50%. Associated anomalies were seen in four patients. Early postoperative periodhadtwo cases of pneumothoraces. At six month follow up, five (25% males and four females (40% had delayed weight gain. Permanent oxygen dependency was seen in two patients. Twenty- six patients underwent thoracotomy. Mortality rate was 13%. Base deficit at the time of admission was greater in those patients who eventually died, (-8.6 ± 1.2 versus -3.1 ± 0.4 (P = 0.0003. There were two deaths in the bilobar involvement group and two in the unilobar involvement group (P = 0.07, near significant. Conclusion: This study confirms that the number of affected lobes and base deficit at the time of admission were associated with significantly increased mortality.

    This study aims to review flexion type supracondylar humerus fractures in children and treatment options. Forty-seven patients (26 males, 21 females; mean age 8.6±3.2 years; range 4 to 15 years) who admitted to and were hospitalized in a pediatric orthopedics clinic between January 2002 and January 2014 due to flexion type supracondylar humerus fracture were included in this retrospective study. Fractures were classified according to Wilkins modification of Gartland system. Closed reduction and percutaneous pinning (CRPP) were administered in all patients with type 2 and 3 fractures. An overhead traction or open reduction was applied when closed reduction could not be achieved with three manipulations. Patients were evaluated clinically and radiologically. The results were graded according to Flynn criteria. Four patients with type 1 fracture were treated conservatively. Of the remaining patients, we were able to perform CRPP successfully in 36 (83.7%). While six patients (14%) were treated with open reduction and internal fixation, one patient (2.1%) was treated with overhead traction. The results were excellent or good in 44 patients (93.7%). Compared with extension type fractures, these fractures are seen in older children and are rarer. One should be prepared to perform open reduction especially for type 3 fractures. In our study, results of patients with type 3 fractures treated with CRPP were superior.

    Full Text Available Abstract Multiple osteochondromas (MO are a rare autosomal dominant disorder characterized by the presence of osteochondromas located on the long bones and axial skeleton. Patients present with growth disturbances and angular deformities of the long bones as well as limited motion of affected joints. Forearm involvement is found in a considerable number of patients and may vary from the presence of a simple osteochondroma to severe forearm deformities and radial head dislocation. Patients encounter a variety of problems and symptoms e.g., pain, functional impairment, loss of strength and cosmetic concerns. Several surgical procedures are offered from excision of symptomatic osteochondromas to challenging reconstructions of forearm deformities. We describe visualizing, planning and treating these forearm deformities in MO and, in particular, a detailed account of the surgical correction of Masada type I and Masada type II MO forearm deformities.

    We reviewed data collected from 1993 to 2004 as part of the routine activities of the national tuberculosis (TB) control programme (NTP) in Morocco. More than 1 million household TB contacts were identified in approximately 200,000 investigations. On average, 77% of identified contacts were screened every year; overall prevalence was 2.5%. The proportion of TB cases identified in household contacts of registered cases was 5.6%. This was significantly higher in children under 10 years and in patients registered and diagnosed with symptomatic primary complex. Performing TB contact investigations as part of the routine activities of NTP services is feasible in low-middle-income countries.

    To characterize clinically all of the patients with spontaneous pneumomediastinum (SPM) admitted to an adult pulmonology ward in Lisbon, Portugal. This was a retrospective descriptive study of all adult patients (≥ 18 years of age) diagnosed with SPM between January of 2004 and September of 2015. At least one predisposing factor was identified in most (88.9%) of the 18 patients who presented with SPM during the study period. With regard to precipitating factors, bouts of cough were present in 50.0% of the patients. Other precipitating factors included a sudden increase in tobacco consumption, inhaled drug use, occupational inhalation of varnish fumes, intense exercise, and vomiting. The most common complaints were dyspnea (in 83.3%) and chest pain (in 77.8%). Other complaints included cough, neck pain, dysphagia, and odynophagia. Subcutaneous emphysema was found in most of the patients. The diagnosis of SPM was based on chest X-ray findings in 61.1% of the patients. Although SPM is a rare condition, it should be considered in the differential diagnosis of chest pain and dyspnea. It can develop without a triggering event or conclusive findings on a chest X-ray, which is usually sufficient for diagnosis.

Estudo descritivo retrospectivo no qual foram analisados todos os pacientes adultos (≥ 18 anos de idade) com diagnóstico de PME entre janeiro de 2004 e setembro de 2015. Pelo menos um fator predisponente foi identificado na maioria (isto é, em 88,9%) dos 18 pacientes que apresentaram PME durante o período de estudo. No tocante a fatores precipitantes, crises de tosse ocorreram em 50,0% dos pacientes. Outros fatores precipitantes foram um aumento repentino do consumo de tabaco, uso de drogas inalatórias, inalação ocupacional de vapores de vernizes, exercício intenso e vômitos. As queixas mais comuns foram dispneia (em 83,3%) e dor torácica (em 77,8%). Outras queixas foram tosse, cervicalgia, disfagia e odinofagia. Constatou-se a presença de enfisema subcutâneo na maioria dos pacientes. O diagnóstico de PME baseou-se na radiografia de tórax em 61,1% dos pacientes. Embora seja uma doença rara, o PME deve ser levado em conta no diagnóstico diferencial de dor torácica e dispneia. O PME pode surgir sem um evento desencadeante e sem achados conclusivos na radiografia de tórax, que é geralmente suficiente para o diagnóstico.

    Conclusion: In order to allow prompt diagnosis of congenital VCP, FB should be performed in every newborn infant with stridor. Patients with congenital VCP should undergo additional imaging studies to detect any associated neurological abnormalities and intrathoracic comorbidities. The majority of patients can be managed conservatively and monitored carefully using serial FB. Corrective surgery should be reserved for those with a lack of resolution at prolonged follow-up, and those with significant comorbidities.

    Full Text Available Protein-losing enteropathy (PLE is a complication in some systemic lupus erythematosus (SLE patients that is often misdiagnosed. With this study, we provide insight into clinical characteristics, laboratory characteristics, diagnostic tests, risk factors, treatment, and prognosis of the disease.A retrospective, case-control study was performed in 44 patients with SLE-related PLE (PLE group and 88 patients with active SLE (control group admitted to our care from January 2000-January 2012. Risk factors for SLE-related PLE were examined, and we analyzed the accuracy of single and combined laboratory characteristics in discriminating SLE-related PLE from active SLE. Serum albumin and C3 levels were measured as outcome during and after treatment with corticosteroids and immunosuppressive agents.The PLE group had lower mean serum albumin and 24-hour urine protein levels, higher mean total plasma cholesterol levels, and greater frequencies of anti-SSA and SSB seropositivity compared with the control group. Anti-SSA seropositivity, hypoalbuminemia, and hypercholesterolemia were independent risk factors for SLE-related PLE. The simultaneous presence of serum albumin (<22 g/l and 24-hour urine protein (<0.8 g/24 h had high specificity, positive predictive value, negative predictive value, and positive likelihood ratio, a low negative likelihood ratio and no significant reduction in sensitivity. High dosage of glucocorticosteroid combined with cyclophosphomide were mostly prescribed for SLE-related PLE.SLE-related PLE should be considered when an SLE patient presents with generalized edema, anti-SSA antibody seropositivity, hypercholesterolemia, severe hypoalbuminemia, and low 24-hour urine protein levels. Aggressive treatment for lupus might improve prognosis.

    Although the existing evidence suggests that there is no obviously superior conservative method for treating cervical intraepithelial neoplasia (CIN), one of the most widely used is the large loop excision of the transformation zone (LLETZ). A total of 897 women who were treated with LLETZ at our colposcopy clinic from 1989 to 2000 were retrospectively studied. Forty women did not have significant cervical pathology (4.5% over-treatment rate). Clear margins of excision were obtained in 748 (88.5%) of the 845 cases of CIN or microinvasive cancers. Treatment failure rates were 4.7% for clear margins and 26.8% for involved or uncertain. LLETZ is a fast and reliable method of treating CIN and microinvasive carcinoma. Generalized cauterization of the resulting crater should be avoided and satellite HPV lesions ablated. Involved margins have a higher treatmentfailure rate, therefore a larger excision is recommended as cervical craters regenerate. Treatment in pregnant women can be delayed until postpartum provided they have adequate surveillance during pregnancy.

  9. "Wild Child": how three principles of healing organized 12 years of psychotherapy.

    Terr, Lenore C

    2003-12-01

    Methods of conducting psychotherapy in the most severe forms of childhood posttraumatic stress disorder (PTSD), especially in those traumas discovered very early in life, are rarely reported. This paper presents such a report and in the process emphasizes three elements of treatment: abreaction (full emotional expression of the traumatic experience), context (understanding and gaining perspective on the experience), and correction (finding ways personally or through society to prevent or repair such experiences). With traumatized children, all three elements may be inserted into their therapeutic play, art, and/or talk. An overarching mood of light humor helps the transference stay positive and the child interested. The case of "Cammie," an infant who was bitten, shaken, and sexually abused, and whose 25-day-old sister was discovered at home, murdered, is the subject of this report. This little girl, upon removal at 13 months of age from her home of origin, growled, bit, sniffed sexual organs, rarely spoke, and behaved like the "feral children" described in the classic psychiatric literature. Two respected professionals diagnosed her as mentally retarded. A year in an outstanding foster home did little to improve her. At 29 months of age she was brought to the author, who saw enough imagination and pithy language to believe the child to be intelligent but severely traumatized. The author had begun to conceptualize three principles of PTSD treatment after a study of normal schoolchildren's reactions to the 1986 Challenger disaster. These three principles were used with varying emphases at different phases throughout the "wild child's" 12-year course of once-monthly therapy. Improvement beyond anyone's expectations ensued.

    Parenteral antibiotic treatment has been classically developed in hospitals and is considered as a hospital procedure. The development of Hospital at Home Units (HHU) has led to an increase in outpatient parenteral antibiotic therapy (OPAT) in paediatrics patients. The objective of this study is to describe our experience, as an HHU integrated within a Paediatric Department, in home antimicrobial therapy over a period of 12 years. This prospective and descriptive study included every patient with a disease requiring parenteral antimicrobial therapy who was admitted to our HHU from January 2000 to December 2012. During the study there were 163 cases on OPAT. The mean age of the patients was 11.1 years, and the sample group was comprised of 33 males and 22 feamales. The main sources of the treated infections were respiratory tract (76%), catheter-related bloodstream (9.2%), and urinary tract infections (5.5%). Amikacin was the most widely used antibiotic. Almost all treatments (96.6%) were via an intravenous route. Catheter-associated complications were more common than drug-associated complications. Successful at-home treatment was observed in 90.2% of cases. OPAT is a good and safe alternative in many paediatric diseases. Copyright © 2013 Asociación Española de Pediatría.

    O'Brien, Deirdre

    2012-02-01

    BACKGROUND: Candida infection of the central nervous system (CNS) following neurosurgery is relatively unusual but is associated with significant morbidity and mortality. We present our experience with this infection in adults and discuss clinical characteristics, treatment options, and outcome. METHODS: All episodes of Candida isolated from the central nervous system were identified by searching our laboratory database. Review of the cases was performed by means of a retrospective chart review. RESULTS: Eleven episodes of Candida CSF infection following neurosurgery were identified over a 12-year period. Candida albicans was the predominant species isolated (n = 8, 73%). All infections were associated with foreign intracranial material, nine with external ventricular drains (82%), one with a ventriculoperitoneal shunt, one with a lumbar drain, and one with Gliadel wafers (1,3-bis [2-chloroethyl]-1-nitrosurea). Fluconazole or liposomal amphotericin B were the most common anti-fungal agents used. The mortality rate identified in our series was 27%. CONCLUSIONS: Candida infection following neurosurgery remains a relatively rare occurrence but one that causes significant mortality. These are complex infections, the management of which benefits from a close liaison between the clinical microbiologist and neurosurgeon. Prompt initiation of antifungal agents and removal of infected devices offers the best hope of a cure.

    To study the association between parental corporal punishment and psychological maladjustment in children. Potential mediating variables of this association were explored. The relationship between corporal punishment and physical abuse was also investigated. DESIGN, SETTING AND SAMPLE: The children (N = 1226, 12-year olds) were selected from government schools in the Colombo district, using a stratified random sampling technique. Self-administered instruments, adapted and validated to the Sri Lankan context were used. The experience of parental corporal punishment was shown to be moderately, but significantly, associated with psychological maladjustment in children. This association was enhanced by the child witnessing or experiencing non-parent-to-child violence (eg. domestic, community, teacher and peer violence). The extent of the child's support network, the nature of the parent-child relationship and the child's attitude to corporal punishment did not significantly alter the association between corporal punishment and psychological maladjustment. Corporal punishment was also moderately, but significantly, associated with child physical abuse. Parental corporal punishment is associated with psychological harm for children; this association is further enhanced by other forms of violence in a child's life.

    Full Text Available Generally, 15-25% of general population experience urticaria during their life. The prevalence of chronic urticaria is about 0.1-0.3% in children and most often occurs between ages of 6-11 years. There are several causes for development of chronic urticaria. Known etiologies of chronic urticaria in children vary from 21% to 83%. Chronic urticaria caused by infections is more common in children than adults. Diagnosis of chronic urticaria is based on clinical history and physical examination and routine laboratory testing in the absence of a clinical history is rarely helpful. Similar to adults, antihistamines are the first line of treatment. Omalizumab as a biological engineering molecule is a recombinant humanized monoclonal antibody, which targets the CH3 domain of the ε chain of the free IgE. Omalizumab has been used in patients with H1-antihistamine-refractory chronic idiopathic urticaria (CIU. Here in we made a review about possible mechanisms by which omalizumab may be effective in children above 12 years with chronic urticaria, and also focused on its therapeutic effects, onset criteria and possible side effects.

She was diagnosed with allograft hydronephrosis and double J stents obstruction by calculi formation after transplantation and treated with triplicate stents replacements in another hospital without clinical manifestations improvements. Through detailed exploration of medical history, we conclude that the abnormal calculi formation is due to the calcitriol (1,25-dihydroxyvitamin D3 administration, a drug which can increase renal tubular reabsorption of calcium for treating posttransplant HPT bone disease. After discontinuing calcitriol, the patient was stone-free and had a good recovery without severe complications during the 9-month follow-up. Our novel findings may provide an important clue and approach to managing formidable repetitive double J stent calculi formation in the clinical trial.

    Investigated anxiety symptoms in normal school children 4 to 12 years of age (N = 190). The percentages of children reporting fears, worries, and scary dreams were 75.8, 67.4, and 80.5%, respectively, indicating that these anxiety symptoms are quite common among children. Inspection of the developmental pattern of these phenomena revealed that fears and scary dreams were common among 4- to 6-year-olds, became even more prominent in 7- to 9-year-olds, and then decreased in frequency in 10- to 12-year-olds. The developmental course of worry deviated from this pattern. This phenomenon was clearly more prevalent in older children (i.e., 7- to 12-year-olds) than in younger children. Furthermore, although the frequency of certain types of fears, worries, and dreams were found to change across age groups (e.g., the prevalence of fears and scary dreams pertaining to imaginary creatures decreased with age, whereas worry about test performance increased with age), the top intense fears, worries, and scary dreams remained relatively unchanged across age levels. An examination of the origins of these common anxiety phenomena showed that for fears and scary dreams, information was the most commonly reported pathway, whereas for worry, conditioning experiences were more prominent.

    Renal calculi are one of the most painful urologic disorders causing 3 million treatments per year in the United States. The objective of this paper is the automated detection of renal calculi from CT colonography (CTC) images on which they are one of the major extracolonic findings. However, the primary purpose of the CTC protocols is not for the detection of renal calculi, but for screening of colon cancer. The kidneys are imaged with significant amounts of noise in the non-contrast CTC images, which makes the detection of renal calculi extremely challenging. We propose a computer-aided diagnosis method to detect renal calculi in CTC images. It is built on three novel techniques: 1) total variation (TV) flow to reduce image noise while keeping calculi, 2) maximally stable extremal region (MSER) features to find calculus candidates, 3) salient feature descriptors based on intensity properties to train a support vector machine classifier and filter false positives. We selected 23 CTC cases with 36 renal calculi to analyze the detection algorithm. The calculus size ranged from 1.0mm to 6.8mm. Fifteen cases were selected as the training dataset, and the remaining eight cases were used for the testing dataset. The area under the receiver operating characteristic curve (AUC) values were 0.92 in the training datasets and 0.93 in the testing datasets. The testing dataset confidence interval for AUC reported by ROCKIT was [0.8799, 0.9591] and the training dataset was [0.8974, 0.9642]. These encouraging results demonstrated that our detection algorithm can robustly and accurately identify renal calculi from CTC images.

    To investigate the therapeutic effects of the aqueous extract of Cerasus Avium stem on kidney calculi. In this experimental study, forty-eight (48) male Wistar rats were randomly allocated into six (6) groups and were studied during a 30 day period. Group A served as normal control and Group B received 1% ethylene glycol in drinking water (EG group). C, D, E, and F Groups, received 1% ethylene glycol from day 1 and were used as prevention and treatment subjects. Rats in prevention groups of low dose (C) and high dose (D) extract, were gavaged with 200 and 400 mg/kg extract respectively from first day of the experiment and treatmentgroups of low dose (E) and high dose (F) extract, were gavaged with 200 and 400 mg/kg extract respectively from the 15th day of the experiment. On the 30th days of the experiment, serum level of magnesium and potassium decreased significantly in EG group compared with A,C,D,E and F groups (P < .05), while serum level of calcium, creatinine, uric acid, sodium and urine level of calcium, creatinine, uric acid, increased significantly in EG group compared with A,C,D,E and F groups (P < .05). In the prevention and treatment groups, the number of deposits decreased significantly compared with EG group on the 30th day (P < .05). Cerasus Avium stem has a therapeutic effect on calcium oxalate stones in rats with nephrolithiasis and reduces the number of calcium oxalate deposits.

  1. Effective Root-Finding Methods for Nonlinear Equations Based on Multiplicative Calculi

    Full Text Available In recent studies, papers related to the multiplicative based numerical methods demonstrate applicability and efficiency of these methods. Numerical root-finding methods are essential for nonlinear equations and have a wide range of applications in science and engineering. Therefore, the idea of root-finding methods based on multiplicative and Volterra calculi is self-evident. Newton-Raphson, Halley, Broyden, and perturbed root-finding methods are used in numerical analysis for approximating the roots of nonlinear equations. In this paper, Newton-Raphson methods and consequently perturbed root-finding methods are developed in the frameworks of multiplicative and Volterra calculi. The efficiency of these proposed root-finding methods is exposed by examples, and the results are compared with some ordinary methods. One of the striking results of the proposed method is that the rate of convergence for many problems are considerably larger than the original methods.

    Hereditary xanthinuria is an extremely rare purine metabolism disorder caused by a genetic abnormality in xanthine dehydrogenase. A new case of hereditary xanthinuria type 1 accompanied by bilateral renal calculi was encountered. We performed an allopurinol loading test and diagnosed classical type 1 xanthinuria. Through genetic diagnosis, we identified a mutation site in the xanthine dehydrogenase gene. Genetic analysis revealed a homozygous deletion of cytosine 2,567 in the xanthine dehydrogenase gene, and as a result, a stop codon was formed at position 928. Renal failure caused by the deposition of xanthine crystals is a known complication because xanthine is poorly soluble in water. With high fluid intake and low purine diet, no significant increase in calculi has been observed in this patient for 2 years.

    Full Text Available The present report was carried out to manage a case of calculi in the bladder of African spurred tortoise. A 6 year old African spurred tortoise presented with history of anorexia and whitish discharged from the vent. Upon physical examination, the tortoise were 10% dehydrated, hindlegs muscle wasting and whitish materials came out from the vent. Plain radiograph revealed increased radiopacity in the bladder and also both right and left kidney. Contrast gastrointestinal radiograph showed less possibility of foreign body. Inconclusive radiological findings required the decision to proceed with exploratory transplastron coeliotomy by using dental burr. About 4 cm solid, hard whitish mass was removed from the bladder and both kidney was congested with whitish material. The findings were suggestive for urates crystal calculi based on histology result. [Vet. World 2012; 5(8.000: 489-492

    To report the experience of the authors with efficacy and toxicity of periocular chemotherapy over a 12-year period. 102 periocular injections of 2 cc (10 mg of carboplatin/1 cc) were given every 4-6 weeks in 33 eyes of 29 patients. Patient's data were reviewed retrospectively. Thirty-three eyes were followed for 7-148 months following initiation of periocular injections, and 13 (39%) have avoided enucleation. There were two cases of second malignancy resulting in one death and one survivor, two survivors of metastatic disease, and two survivors of orbital recurrence. Twenty eyes were enucleated for disease progression at a mean time of 15 months postinitiation of periocular carboplatin (POC). The Kaplan-Meier estimate of eye survival at 36 months is 36%. Eleven of the 13 salvaged eyes received concurrent treatment with chemotherapy (n=4, 30%), external beam radiation and chemotherapy in (n=6, 46%), or brachytherapy (n=1, 8%). Two of the salvaged eyes (16%) were treated with POC alone. Orbital swelling occurred in 14/33 (42%) eyes. There were no symptomatic motility disorders. One severe toxicity reaction resulted in acute loss of vision, down to light perception, which failed to recover and one eye had progression of optic nerve pallor. This paper demonstrates that POC has limited short-term and long-term systemic toxicity and most of the ocular complications were acute, not delayed. Only two select cases showed long-term complete responses to POC alone and the data do not support the use as monotherapy, although where it was used in combination with other modalities, 39% of the eyes were saved.

    In dual energy (DE) computed tomography (CT), spectral shaping by additional filtration of the high energy spectrum can theoretically improve dual energy contrast. The aim of this in vitro study was to examine the influence of an additional tin filter for the differentiation of human urinary calculi by dual energy CT. A total of 36 pure human urinary calculi (uric acid, cystine, calciumoxalate monohydrate, calciumoxalate dihydrate, carbonatapatite, brushite, average diameter 10.5 mm) were placed in a phantom and imaged with 2 dual source CT scanners. One scanner was equipped with an additional tin (Sn) filter. Different combinations of tube voltages (140/80 kV, 140/100 kV, Sn140/100 kV, Sn140/80 kV, with Sn140 referring to 140 kV with the tin filter) were applied. Tube currents were adapted to yield comparable dose indices. Low- and high energy images were reconstructed. The calculi were segmented semiautomatically in the datasets and DE ratios (attenuation@low_kV/attenuation@high_kV) and were calculated for each calculus. DE contrasts (DE-ratio_material1/DE-ratio_material2) were computed for uric acid, cystine and calcified calculi and compared between the combinations of tube voltages. Using exclusively DE ratios, all uric acid, cystine and calcified calculi (as a group) could be differentiated in all protocols; the calcified calculi could not be differentiated among each other in any examination protocol. The highest DE ratios and DE contrasts were measured for the Sn140/80 protocol (53%-62% higher DE contrast than in the 140/80 kV protocol without additional filtration). The DE ratios and DE contrasts of the 80/140 kV and 100/Sn140 kV protocols were comparable. Uric acid, cystine and calcified calculi could be reliably differentiated by any of the protocols. A dose-neutral gain of DE contrast was found in the Sn-filter protocols, which might improve the differentiation of smaller calculi (Sn140/80 kV) and improve image quality and calculi differentiation in

    In the following study, we observe the progress of various invasive calculi treatments that have taken place in our hospital in the last 15 years. We extracted data from our hospital database on patients who underwent extracorporeal shock wave lithotripsy (ESWL), endoscopic surgery and open surgery. We analyzed how the incidence of these treatments has evolved over the last 15 years. We also studied the number of publications in PubMed that reference invasive calculi treatments. From January 1998 to December 2012, a total of 10,947 patients were treated instrumentally for lithiasis, 9,695 of whom (90.4%) underwent ESWL and 1,034 of whom underwent endoscopic or open surgery (9.6%). The incidence of lithotripsy treatments reached its maximum in 2006, with a progressive reduction thereafter. The incidence of endoscopic surgery increased progressively until 2009 and then leveled off. We can see how in recent years there has been a clear increase in the number of studies that have covered endoscopic surgery, with a decreasing number covering ESWL. In our community, ESWL remains the most widely used invasive treatment for calculi. In recent years, there has been a reduction in the number of ESWL treatments and an increase in the number of endoscopic treatments, with open surgery showing a clearly decreasing trend.

    Nephrolitiasis, once considered an adult disease, has become increasingly prevalent in children, with na increase from 6% to 10 % annually in past 25 years. Kidney stones in pediatric population can result from metabolic diseases in up to 50% of children affected. Other factors associated with litiasis are infection, dietary factors, and anatomic malformations of urinary tract. Standard treatment procedures for pediatric population are similar to adult population. Extracorporeal shock wave lithotripsy (ESWL), ureterorenoscopy (URS), percutaneous nepfrolithotomy (PCNL), as well as laparoscopic and retroperitoneoscopic approaches can be indicated in selected cases. The advantages of laparoscopic or retroperitoneoscopic approaches are shorter mean operation time, no trauma of renal parenchyma, lower bleeding risk, and higher stone-free rates, especially in pelvic calculi with extrarenal pelvis, where the stone is removed intact. A 10 year-old girl presented with right abdominal flank pain, macroscopic hematuria,with previous history of urinary infections.. Further investigation showed an 1,5 centimeter calculi in right kidney pelvis. A previous ureterorenoscopy was tried with no success, and a double J catheter was placed. After discussing options, a retroperitoneoscopic pielolithotomy was performed. The procedure occurred with no complications, and the calculi was completely removed. The foley catheter was removed in first postoperative day and she was discharged 2 days after surgery. Double J stent was removed after 2 weeks. Retroperitoneoscopic pielolithotomy is a feasible and safe procedure in children, with same outcomes of the procedure for adult population.

    Advances in endoscopic techniques have transformed the management of urolithiasis. We sought to evaluate the role of such urological interventions for the treatment of complex biliary calculi. We conducted a retrospective review of all patients (n=9) undergoing percutaneous holmium laser lithotripsy for complicated biliary calculi over a 4-year period (12/2003 to 12/2007). All previously failed standard techniques include ERCP with sphincterotomy (n=6), PTHC (n=7), or both of these. Access to the biliary system was obtained via an existing percutaneous transhepatic catheter or T-tube tracts. Endoscopic holmium laser lithotripsy was performed via a flexible cystoscope or ureteroscope. Stone clearance was confirmed intra- and post-operatively. A percutaneous transhepatic drain was left indwelling for follow-up imaging. Mean patient age was 65.6 years (range, 38 to 92). Total stone burden ranged from 1.7 cm to 5 cm. All 9 patients had stones located in the CBD, with 2 patients also having additional stones within the hepatic ducts. All 9 patients (100%) were visually stone-free after one endoscopic procedure. No major perioperative complications occurred. Mean length of stay was 2.4 days. At a mean radiological follow-up of 5.4 months (range, 0.5 to 21), no stone recurrence was noted. Percutaneous endoscopic holmium laser lithotripsy is a minimally invasive alternative to open salvage surgery for complex biliary calculi refractory to standard approaches. This treatment is both safe and efficacious. Success depends on a multidisciplinary approach.

    Nephrocalcinosis and/or urinary calculi are rare in infants. Furosemide treatment during the neonatal period, vitamin D intoxication, hereditary diseases such as hyperoxaluria or distal tubular acidosis are among the most common aetiologies. We report the case of a 6-month-old boy with an extra-hepatic biliary duct atresia treated by the Kasai procedure and a gastro-oesophageal reflux treated with a silicate containing milk thickener (Gelopectose, 5.5% colloidal silicate) since the neonatal period. He did not present any other endogenous risk factor for urinary stone formation (normal urinary calcium/creatinine ratio; normal urinary magnesium excretion). The nephrolithiasis was discovered as the boy presented painful episodes of macroscopic haematuria. Ultrasound examination revealed bilateral nephrocalcinosis and multiple bilateral calculi without infection or urinary obstruction. Infrared spectroscopy revealed silicate as the major component suggesting silicate absorption to be responsible for the described symptoms. After replacement of the silicate-containing agent by a silicate-free milk thickener, the lesions were completely reversible as confirmed by repeated renal ultrasound examinations over a 2-month period. Silicate-containing milk thickeners can be responsible for urinary calculi and/or nephrocalcinosis.

    Full Text Available Purpose: to determine the level of physical development and physical preparedness of weight-lifters of 10–12 years old. Material & Methods: boys of 10–12 years old, who go in for weightlifting sections in CYSS HTZ, and also in sports boarding school No 2 of Kharkiv, participated in this research. 34 boys were attracted to the experiment. Research methods: theoretical method and generalization of literature, pedagogical observation, pedagogical experiment, method of mathematical statistics. Results: differences in intensity of gain of indicators of physical development for the biennium of observations display unevenness and heterochrony of ripening of organism of children were found. The noticeable difference in intensity of gain of the majority of the studied indicators of physical development is noted even for such rather short period (two years. The increase during the whole biennium is established for absolute values of the general physical operability of the tested. However, the size of relative intensity of gain of absolute values of general physical working capacity at stages of observations is different: the first year – 10,48%, the second – 0,86% (t=22,3; р<0,01. In other words, indicators of general physical working capacity considerably grow for the first year of observations (10–11 years old, and practically do not change for the second year (11–12 years old. Conclusions: the established decrease in relative sizes of the general physical working capacity, which is noted at boys in total with the deterioration in results in run at distance of 1000 m, allowed to draw conclusion on the underdevelopment at them the major physical qualities and systems of organism, which define endurance and general physical working capacity. Undoubtedly, the insufficient level of endurance and general physical working capacity reduces adaptation opportunities of boys-weight-lifters.

    Three hundred seventeen specimens of urinary calculi of renal origin from 214 female dogs and 103 male dogs, and 71 specimens of urinary calculi of renal origin from 38 female cats and 33 male cats were submitted for mineral analysis between July 1, 1981, and December 31, 1993. Among dogs, 45 breeds were affected with renal calculi. Thirty-three breeds and a crossbred group were represented among females, but 8 breeds and the crossbred group accounted for 81% of the total. Among male dogs, 30 breeds and a crossbred group were represented, but 7 breeds and the crossbred group accounted for 69% of the total. Among cats, 10 breeds and a crossbred group were represented. Dogs and cats with renal calculi were older than those of 2 comparison population groups. More than one-half of the renal calculi in both dogs and cats were from the 1st known episode of urolithiasis. The risk of formation of renal calculi was found to be higher for cats than for dogs, when compared to other stone-forming cats and dogs (approximately 4.95 per 100 stone-forming cats and 2.88 per 100 stone-forming dogs). Among dogs, breeds at highest risk of developing renal calculi were Miniature Schnauzers, Shih Tzus, Lhasa Aposos, Yorkshire Terriers, and female Pugs. Also at high risk were male Dalmatians and male Basset Hounds. Among small dogs, females generally were at higher risk of developing renal calculi than were males. Regardless of size, terrier breed males generally were at higher risk of developing renal calculi. Breeds of dogs at low risk for development of renal calculi included crossbreds. German Shepherd Dogs, Labrador Retrievers, Golden Retrievers, and female Dachshunds. When only 1 kidney was involved, the risk of left renal calculus was greatest for both dogs and cats, but bilateral renal involvement was relatively common in both species (19% and 9%, respectively). Among dogs, specimens composed of 1 mineral substance (e.g., struvite) occurred more often in males (58.3%) than in

    Dental caries and trauma are the most common oral health problems for many decades. There is need for prevalence data to analyze the nature of the problems and to take necessary steps in improving public health. To assess the prevalence of dental caries and traumatic dental injuries among schoolchildren of age 6 to 12 years in Bhopal city. Cross-sectional study design was selected. Universal sampling method was followed in this study. A total of 1,204 children were examined. The distribution of samples was done based on age, gender, residing area, and type of school. Data were collected and statistically evaluated under chi-square test and analysis of variance. The overall caries experience (73.17%) was found to be higher than that of traumatic injury experience (20.9%). There was age-related correlation between age and decay, missing, and filled teeth score. Since most injuries occur at home or at school, educating the individual is the key that will have a great impact on the prognosis of traumatic injuries. Also good food habits need to be instilled in children from a tender age with the help of parents, which is the ultimate solution to fight caries.

    Gendicine (Recombinant Human p53 Adenovirus, AdRSV-p53), developed by Shenzhen SiBiono GeneTech Company, was approved by CFDA in 2003. It has been used in clinical oncology for 12 years since it entered the market in 2004. As the first-in-class product for cancer gene therapy, Gendicine met its expectation and demonstrated with ample clinical data that it is safe and effective for treating cancer. SiBiono manufactured 41 batches in compliant with CFDA QC/QA requirements. Total 169,571 vials (1.0x1012 vector particles per vial) were used in more than 50,000 patients, among them about 5,000 were international form over 50 nations outside China. Comparing with the first-line standard therapies, intratumor injection of Gendicine combined with chemotherapy and radiotherapy resulted in response rate significantly higher than chemo or radiotherapy alone. The approved indication for Gendicine is Head & Neck Cancer, including NPC. However, Gendicine has been successfully applied for various types and at different disease stage cancers. Furthermore, Gendicine combination regimen has brought long-term benefits to the treated patients with 5-8 year progression-free survival significantly longer than standard therapy alone. Gendicine is a type of biological therapy and is minimally invasive via intratumor injection, intra-cavity or vascular infusion. No serious adverse event reported on Gendicine, except the vector-associated transient fever, which occurred in 50-60% patients treated. The fever, ranged 38-39.50C, took place within 24 hours after Gendicine administration and persisted a few hours. In this review, 30 clinical studies on Gendicine combination regimen with published data and 10 studies with long-term survival follow-up data are summarized and reported. Various types of cancer and a few special clinical cases treated with Gendicine are analyzed. Gendicine's manufacture accomplishments and clinical experience may cast some lights for the international gene therapy

    The aim of the study was to review the operative experiences of emergency hysterectomy for life-threatening postpartum hemorrhage (PPH) performed over a 12-year period at Fujian Provincial Maternity and Children's Hospital; to examine the incidence and risk factors for emergency obstetric hysterectomy; and to evaluate the curative effectiveness and safety of subtotal hysterectomy for life-threatening PPH.The records of all cases of emergency obstetric hysterectomy performed at Fujian Maternity and Children Health Hospital between January 2004 and June 2016 were analyzed. The incidence, risk factors, and outcomes of hysterectomy, the peripartum complications, and the coagulation function indices were evaluated.A total of 152,023 of women were delivered. The incidence of emergency postpartum hysterectomy was 0.63 per 1000 deliveries: 96 patients underwent hysterectomy for uncontrolled PPH, 19 (0.207‰) underwent hysterectomy following vaginal delivery, and 77 (1.28‰) underwent the procedure following cesarean delivery (P postpartum prothrombin activity ≤ 50% (61.5%), placenta accreta (43.76%), uterine atony (37.5%), uterine rupture (17.5%), and grand multiparity > 6 (32.3%). Forty-one patients underwent subtotal abdominal hysterectomy (STH) and 55 patients underwent total abdominal hysterectomy (TH). The mean operation time was significantly shorter for TH (193.59 ± 83.41 minutes) than for STH (142.86 ± 78.32 minutes; P = .002). The mean blood loss was significantly greater for TH (6832 ± 787 mL) than for STH (6329 ± 893 mL; P = .003). The mean number of red cell units transfusion was higher during TH (16.24 ± 9.48 units vs 12.43 ± 7.2, respectively; P = .047). Postoperative prothrombin activity was significantly higher than preoperative levels (56.84 ± 14.74 vs 44.39 ± 15.69, respectively; P postpartum prothrombin activity < 50% was the greatest risk factor for hysterectomy in most women who

    An appropriate level of human resources for oral health [HROH] is required to meet the oral health needs of population, and enable maximum improvement in health outcomes. The aim of this study was to estimate the required HROH to meet the oral health needs of the World Health Organization [WHO] reference group of 12-year-olds in China and consider the implications for education, practice, policy and HROH nationally. We estimated the need of HROH to meet the needs of 12-year-olds based on secondary analysis of the epidemiological and questionnaire data from the 3rd Chinese National Oral Health Survey, including caries experience and periodontal factors (calculus), dentally-related behaviour (frequency of toothbrushing and sugar intake), and social factors (parental education). Children's risk for dental caries was classified in four levels from low (level 1) to high (level 4). We built maximum and minimum intervention models of dental care for each risk level, informed by contemporary evidence-based practice. The needs-led HROH model we used in the present study incorporated need for treatment and risk-based prevention using timings verified by experts in China. These findings were used to estimate HROH for the survey sample, extrapolated to 12-year-olds nationally and the total population, taking account of urban and rural coverage, based on different levels of clinical commitment (60-90%). We found that between 40,139 and 51,906 dental professionals were required to deliver care for 12-year-olds nationally based on 80% clinical commitment. We demonstrated that the majority of need for HROH was in the rural population (72.5%). Over 93% of HROH time was dedicated to prevention within the model. Extrapolating the results to the total population, the estimate for HROH nationally was 3.16-4.09 million to achieve national coverage; however, current HROH are only able to serve an estimated 5% of the population with minimum intervention based on a HROH spending 90% of

    2007-04-01

    77 individuals convicted of a drinking and driving (DUI) offense were screened for recidivism approximately 12 years following their first offense. At the time of the initial DUI conviction, participants were administered the MAST and the MMPI-2. Participants' drinking history and driving history and arrest at the time of screening and at a 12-year follow-up were also reviewed. The results indicate that, among DUI recidivists, on average 6 years elapsed between their first and second DUI offenses. Driving history prior to the first DUI offense was predictive of later recidivism. The only significant finding from the MAST and MMPI results was that repeat offenders tended to have higher scores on the L and K validity scales of the MMPI. These results are discussed in the context of Jessor's Problem-Behavior Theory and as well their clinical implications for screening and treatment decisions involving first time DUI offenders.

    One of the etiological factors of dental caries are improper eating habits, which also influence the nutritional state of the organism. This similarity tends to establish the relationship between the intensity of tooth decay, and body weight disorders. The aim of this study was to assess the prevalence of dental caries in 7 and 12-year-old children, depending on the nutritional status. The study included 225 children of both sex, age 7 (132) and 12 years (93) attending to randomly selected schools in Poznań. Dental examination was performed by dentists in schools in artificial light using mirrors and dental probe (criteria according to WHO 1997 ). Based on collected data, caries frequency and caries intensity were calculated (DMF-t -7 and 12-year-olds and dmf-t 7-year olds). Anthropometric measurements such as height and weight were made by school nurses in accordance with guidelines for the performance of screening tests for people of school age. A deficiency or excess body weight in surveyed children rated BMI (Body Mass Index), including percentile ranges for the population of children in Poznań. Assessment of dental caries in groups of pupils were formed due to nutritional status of the respondents i. e. normal-weight and underweight and overweight. Caries frequency in children of normal weight in the population of 7-year-olds was 82.2% and 53.2% of children aged 12 years. In the group of 7-year-old pupils with overweight and underweight was respectively, 95.0% and 90.9%, 84.2% and 50.0% in the older group. A statistically significant difference between the attendance of dental caries in a group of 12-year-old children with overweight and normal weight and its deficiency was show. The average value of dmf-t in 7-year-old children was 4.02, and the DMF-permanent dentition - 0.19 and the children with over- and underweight respectively dmf- 4.25 and 3,82 and DMF- 0.35 and 0,27.

    To investigate the impact of staghorn stone branch number on outcomes of percutaneous nephrolithotomy (PNL). From January 2009 to January 2013, the 371 patients with staghorn stones who were referred to our hospital for PNL were considered for this study. All calculi were showed with CT 3-dimentional reconstruction (3-DR) imaging. The computerized database of the patients had been reviewed. Our exclusion criterion was patients with congenital renal anomalies, such as horse-shoe and ectopic kidneys. And borderline stones that branched to one major calyx only were also not included. From 3-DR images, the number of stone branching into minor renal calices was recorded. We made "3" as the branch breakdown between groups. And the patients were divided into four groups. The number of percutaneous tract, operative time, staged PNL, intra-operative blood loss, complications, stone clearance rate, and postoperative hospital day were compared. The 371 patients (386 renal units) underwent PNL successfully, included 144 single-tract PNL, 242 multi-tract PNL, 97 staged PNL. The average operative time was (100 ± 50) minutes; the average intra-operative blood loss was (83 ± 67) ml. The stone clearance rate were 61.7% (3 days) and 79.5% (3 months). The postoperative hospital stay was (6.9 ± 3.4) days. A significantly higher ratio of multi-tract (χ(2) = 212.220, P PNL (χ(2) = 49.679, P PNL for calculi with stone branch number ≥ 5. There was no statistically meaningful difference among the 4 groups based on Clavien complication system (P = 0.460). The possibility of multi-tract and staged PNL, lower rate of stone clearance and longer postoperative hospital day increase for staghorn calculi with stone branch number more than 5.

    To determine the community incidence of knee pain and associated risk factors over a 12-year period in people over the age of 40 years. A cohort study of knee pain was undertaken in 2156 people from four general practices in North Nottinghamshire, UK. Knee pain was defined as 'pain around the knee for most days of at least a month'. Cumulative incidence over 12 years and person-year incidence rate of knee pain were estimated. Survival analysis was undertaken for time to the onset of knee pain. Hazard ratio (HR) and 95% confidence interval (CI) were estimated for relative risk between exposure and non-exposure. Cox regression model was used to adjust for confounding factors. The 12-year cumulative incidence of knee pain was 34.4% (32% for men and 35% for women), corresponding to an average incidence rate of 32 (31 for men and 34 for women)/1000 person-years. Incident knee pain was associated with female gender (HR 1.27, 95% CI 1.08, 1.49), obesity (1.80; 95% CI 1.37, 2.38), varus (1.68, 95% CI 1.15, 2.47) and valgus (1.83, 95% CI 1.05, 3.20) mal-alignment, and knee injury (2.37, 95% CI 2.98, 2.85). For people over age 40, one in three will develop knee pain within 12 years. On average, the risk of knee pain was 32/1000 person-years. This risk is associated with a variety of constitutional and environmental biomechanical insults to the knee. Some of these could be modified to possibly reduce the incidence of the condition.

Multiple linear regression showed a statistically significant interaction between ward Townsend score, mean DMFT and water fluoridation, showing that the more deprived the area the greater the reduction in tooth decay. At a Townsend score of zero (the English average) there was a predicted 37% reduction in decay in 12-year-olds in fluoridated wards. Tooth decay is strongly associated with social deprivation. The findings confirm that the implementation of water fluoridation has markedly reduced tooth decay in 12-year-old children and that socio-economic dental health inequalities are reduced.

    This study assesses the dental erosion status of 12-year-old Indonesian children and studies the determinants of dental erosion of these children. The survey was performed in 2016 with ethics approval. A multistage cluster proportional to size random sampling method was adopted to select 12-year-old children in 24 primary schools in Jakarta. The parents were asked to complete a self-administered questionnaire concerning their children’s diet and oral health habits. The children were examined by a single calibrated examiner. Detection of dental erosion followed basic erosive wear examination (BEWE) criteria. A total of 487 children participated in the survey. Most children (88%) had at least some signs of erosion (BEWE > 0), with dentin being involved in 50% of the cases (BEWE = 2). Dental erosion was significantly related to gender, the frequencies of citric tea consumption, parent’s dental knowledge, father’s education, and dental caries (OR = 3.148). The 12-year-old Indonesian school children who lived in Jakarta had signs of erosion, although severe erosion was not found. Screening programs should be provided to identify risk groups so early preventive measures can be taken.

    There is a lack of validated instruments for quantifying feeding behavior among parents of older children and adolescents. The Comprehensive Feeding Practices Questionnaire (CFPQ) is a self-report measure to assess multiple parental feeding practices. The CFPQ is originally designed for use with parents of children ranging in age from about 2 to 8 years. It is previously validated with American and French parents of children within this age range. The aim of the present study was to adapt and test the validity of this measure with parents of older children (10-to-12-year-olds) in a Norwegian setting. A sample of 963 parents of 10-to-12-year-olds completed a Norwegian, slightly adapted version of the CFPQ. Scale analyses were performed to test the validity of the instrument in our sample. Although a few problematic items and scales were revealed, scale analyses showed that the psychometric properties of the slightly adapted, Norwegian version of the CFPQ were surprisingly similar to those of the original CFPQ. Our results indicated that the CFPQ, with some small modifications, is a valid tool for measuring multiple parental feeding practices with parents of 10-to 12-year-olds.

    Full Text Available The present study aims to determine the level of oral hygiene, periodontal status and treatment needs, indicating if there are differences between men and women, in 12-year-old students from Castro, Los Lagos region, during March and April of 2014. A cross-sectional study was carried out. A total of 242 12-year-old students from municipal and subsidized private schools in Castro were selected through a stratified random sample representative of each school. Students were evaluated by a calibrated examiner to determine the Simplified Oral Hygiene Index (OHI-S and the Community Periodontal Index of Treatment Needs (CPITN. Data were transferred to a Microsoft Excel spreadsheet and statistically analyzed to calculate the amount and percentage of the variables. Mann-Whitney U-test was used for comparison between genders. From the total, 59.5% of the students have regular hygiene. Also, 86.4% of the assessed adolescents have gingivitis and 13.6% of them have periodontitis. The periodontal treatment need indicates that 58% of the students require oral hygiene instructions and scaling. No statistically significant differences were found for gender. There is a higher prevalence of periodontal diseases associated with regular oral hygiene than the regional and national reference in 12-year-old adolescents in Castro. Then, it is necessary to teach and promote specific public health strategies based on epidemiological data

    Full Text Available Emphysematous pyelonephritis is a life threatening, necrotizing upper urinary tract infection associated with gas within the kidney and/or perinephric space. To prevent mortality from this fulminant infection, early diagnosis is essential. CT scan should be done early in patients with suspected emphysematous pyelonephritis. Here, we present a case of Type II Diabetes Mellitus complicated with left obstructive ureteric calculi, diagnosed on CT scan to have extensive bilateral emphysematous pyelonephritis of class 4. We treated conservatively with antibiotics and DJ stent. The patient responded and a repeat CT scan was done after 4 weeks which showed no evidence of emphysematous pyelonephritis.

    According to current guideline recommendations extracorporeal shock wave lithotripsy (SWL) remains the first choice treatment for small and mid-sized renal calculi. However, the results of SWL treatment for lower pole stones can be disappointing whilst more invasive endoscopic modalities, such as flexible ureterorenoscopy (fURS) and percutaneous nephrolithotomy (PNL) are often considered more effective. This article summarizes a point-counterpoint discussion at the 9th eULIS symposium in Como, Italy, and discusses the potential advantages and disadvantages of the different therapeutic approaches.

    Atmospheric hydrogen (H2) and carbon monoxide (CO) have been measured at the Royal Holloway site, 30km WSW of London, for 12 years. This site receives air that has passed over London when there are easterly winds and cleaner, background air when the wind comes from the SW. H2 and CO mixing ratios are measured continuously at 30 minute intervals on a Trace Analytical Reduction Gas Detector coupled to a HP5890 GC since September 1996, and on a Peak Performer I (or PP1) since July 2007 at 5 minute intervals. Both instruments use 2 1/8" packed columns in series: a Unibeads 1S and a Molecular Sieve 5A. The PP1 detector (Reduced Compound Photometer) is an updated version of the old RGD2, and both use zero air as the carrier gas. CO is calibrated twice a month against NOAA-CMDL standards (mixing ratios range: 186 to 300 ppb). H2 was uncalibrated until 2006, but is now calibrated monthly against internal standards (range 530 to 750 ppb) measured at MPI-Jena as part of the Eurohydros project. A linearity correction is applied to each instrument, based on the standard measurements. A secondary standard is measured before each sample on the GC-RGD and another one is measured 4 to 6 times in a row twice a day on the PP1. A target gas is measured daily on both instruments since September 2008. The secondary standards and the target gas are dry ambient air in 70L stainless steel tanks filled to a pressure of 8 bars. Comparison of results from the two instruments suggests that for the most part the data are in good agreement, but an interlaboratory round robin comparison exercise for the Eurohydros project showed that the RGD is not linear at low values of CO. This is particularly noticeable for CO levels below 150 ppb. The long-term record of CO at Royal Holloway shows a significant decline since the start of the record: the annual mean CO mixing ratio in 2008 was three times lower than in 1997. Flux calculations, by ratio against 222Rn, CH4 and CO2, suggest CO emissions

    Treatment of patients with staghorn calculi with percutaneous nephrolithotomy can be challenging, often necessitating multiple tracts or sessions for complete stone clearance. Although open anatrophic nephrolithotomy can result in higher stone-free rates, it is rarely performed because of increased morbidity. To provide a minimally invasive alternative, we developed the technique of robot-assisted anatrophic nephrolithotomy (RANL) incorporating ice slush for renal hypothermia. Three patients with staghorn calculi (mean total stone volume 12887.67 mm(3)) underwent RANL with iced cold ischemia. A GelPOINT™ port was used for ice slush insertion. Intracorporeal temperatures were cold ischemia. Mean console and cold ischemia times were 167 and 56.7 minutes, respectively. Mean blood loss was 100 mL. There were no complications. Two patients had residual fragments measuring 13 mm, and two 9 mm stones, respectively. RANL with iced cold ischemia is a safe and feasible option that may be considered in patients with staghorn stones. Further study is needed to refine the technique and assess long-term functional outcomes.

    Plasma levels and urinary amino acid excretions were estimated by high-performance liquid chromatography in 15 control subjects and 36 stone formers (SFs) classified according to the stone type: (1) 22 cases with calcium oxalate stones; (2) four cases with pure uric acid stones; (3) 10 cases with magnesium-ammonium phosphate stones, either pure or mixed with apatite. Some types of stones (namely oxalate and uric acid calculi) are mainly formed as a result of a metabolic deficiency that may affect the amino acid metabolism, and thus may be reflected in the urinary amino acid pattern. Data demonstrated clearly that there is a general tendency towards decreased amino acid excretions in all SFs with all types of stones. As a whole, one can observe a higher percentage of patients with calcium oxalate and phosphate calculosis, who have low urine excretions of amino acids; about 50% are the SFs with lower urine excretion of serine, glycine, taurine and i-leucine; the high percentage of patients with CaOX calculi shows lower urine excretions of tyrosine and ornithine.

    We evaluated the efficacy of ureteroscopic therapy (electrohydraulic lithotripsy [EHL] and intraductal laser lithotripsy [ILL]) in patients with challenging biliary stones secondary to anatomic variations resulting from a previous surgical procedure, including liver transplantation. A retrospective chart review was performed for all patients with previous surgical alteration of the gastrointestinal (GI) tract who underwent EHL or ILL via peroral or percutaneous access for choledocholithiasis by a single surgeon at our institution from 2000 to 2012. A database containing clinical and surgical variables was created, and long-term follow-up was conducted (3-138 months; median, 99 months). Thirteen patients (51.7±20.0 years; M:F, 10:3) in whom endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTHC), or both failed were identified. Failure of ERCP/PTHC was because of inaccessibility of the calculi in all cases. Stone clearance was achieved in 12/13 (93%) patients; 8/12 (62%) after one procedure, and 4/12 (31%) after two procedures. One patient with biliary cast syndrome needed four interventions over 9 years. Major complications were low, with only one patient with hypotension and cholangitis that resolved with 24 hours of administration of intravenous fluids and antibiotics. Both endoscopic and percutaneous lithotripsies are effective treatments for refractory biliary calculi resulting from the post-surgical GI tract. Although a staged second procedure may be necessary in patients with significant stone burden, this is significantly better than extensive open surgery.

    The aims of this study were to determine the clinical characteristics of patients with urinary sepsis associated to ureteral calculi admitted to the Intensive Care Unit (ICU), and to identify predictors of mortality in the first 24 hours of admission. A retrospective observational study covering a 16-year period (2006-2011) was carried out. The combined clinical/surgical ICU of a secondary-level University hospital. All patients admitted to the ICU due to obstructive urinary sepsis. None. We analyzed general clinical and laboratory test and urological data. The diagnostic technique, affected side, decompression technique, isolated microorganism and antibiotic therapy used were also considered. The assessment of risk factors was performed by multiple logistic regression analysis. A total of 107 patients admitted to the ICU were included in the study, with a mortality rate of 19.6%. The diagnosis was mainly established by ultrasound, and the most commonly used decompression technique was retrograde JJ stenting. Microorganisms were isolated in 48.6% of the patients. In total, 20.6% of the patients had bacteremia. Multivariate analysis found age, acute renal failure and the use of vasoactive drugs administered continuously for the first 24 hours of admission to be independently associated to mortality. Advanced age, acute renal failure and the need for vasoactive drugs were associated to an increased risk of mortality in patients with urinary sepsis associated to upper urinary tract calculi.

    To determine the risk of concussion among youth football players (ages 8-12 years). Participants included 468 male youth football players in western Pennsylvania during the 2011 youth football season. Incidence rates (IRs) and incidence density ratios (IDRs) of concussion were calculated for games and practices and for age groups. There was a total of 11,338 (8415 practice and 2923 game) athletic exposures (AEs) in the study period, during which 20 medically diagnosed concussions occurred. A majority of concussions were the result of head-to-head (45%) contact. The combined concussion IR for practices and games was 1.76 per 1000 AEs (95% CI 0.99-2.54). The concussion IR was 0.24 per 1000 AEs (95% CI 0.04-0.79) in practices and 6.16 per 1000 AEs (95% CI 3.76-9.54) in games. The IDR for concussions in games to practices was 25.91 (95% CI 6.01-111.70). The IDR of concussions for youth aged 11-12 years compared with youth aged 8-10 years was 2.72 (95% CI 0.66-4.78). The overall IR for concussion in youth football players aged 8-12 years was comparable with that reported previously for high school and collegiate samples. However, participation in games was associated with an increase in risk of concussion compared with practices, which was higher than rates previously reported for high school and collegiate athletes. Younger players were slightly less likely to incur a concussion than were older players. Copyright © 2013 Mosby, Inc. All rights reserved.

    Background Many studies have assessed perspectives of medical students toward institutional diversity, but few of them have attempted to map changes in diversity climate over time. Objective This study aims to investigate changes in diversity climate at a Jesuit medical institution over a 12-year period. Methods In 1999, 334 medical students completed an anonymous self-administered online survey, and 12 years later, 406 students completed a comparable survey in 2011. Chi-square tests assessed the differences in percent responses to questions of the two surveys, related to three identities: gender, race, and sexual orientation. Results The 1999 versus 2011 samples were 46% versus 49% female, 61% versus 61% Caucasian, and 41% vs. 39% aged 25 years or older. Findings suggested improvements in medical students’ perceptions surrounding equality ‘in general’ across the three identities (p<0.001); ‘in the practice of medicine’ based on gender (p<0.001), race/ethnicity (p=0.60), and sexual orientation (p=0.43); as well as in the medical school curriculum, including course text content, professor’s delivery and student–faculty interaction (p<0.001) across the three identities. There was a statistically significant decrease in experienced or witnessed events related to gender bias (p<0.001) from 1999 to 2011; however, reported events of bias based on race/ethnicity (p=0.69) and sexual orientation (p=0.58) only showed small decreases. Conclusions It may be postulated that the improvement in students’ self-perceptions of equality and diversity over the past 12 years may have been influenced by a generational acceptance of cultural diversity and, the inclusion of diversity training courses within the medical curriculum. Diversity training related to race and sexual orientation should be expanded, including a follow-up survey to assess the effectiveness of any intervention. PMID:24581334

    Undifferentiated sarcomas are rare tumors not classified into any sarcoma subtype. Due to their rarity, imaging findings of undifferentiated sarcomas are poorly characterized. The purpose of this report was to present imaging findings of a pathologically confirmed undifferentiated sarcoma originated from the left kidney of a 12-year-old boy. The mass was infiltrative involving the renal pelvis. It mimicked massive hilar lymphadenopathy with a preserved renal contour visible by both ultrasonography and CT. Renal vein thrombosis was also observed. Although undifferentiated sarcomas are rare, they should be considered in differential diagnosis of infiltrative renal masses with renal pelvis invasion in children.

We present a case of GCA in a 12-year-old girl with severe headache and tender scalp especially over the right temporal area. The right superficial temporal artery was cord like and nodular and the pulsations were barely felt. Several small tender nodular swellings were felt in the occipital area. She had been previously diagnosed as a case of nephrotic syndrome due to underlying membranoproliferative glomerulonephritis. This report is aimed at drawing attention to this rare form of vasculitis in children aiming at decreasing its morbidities.

    Personality may be an important yet understudied influence on childhood obesity. We investigated the association between children's personality traits and weight status in a sample of 1533 6-12 year olds. Mothers rated their child's personality using the Norwegian Hierarchical Personality Inventory for Children, and reported on their child's height and weight. Relative to their normal weight peers, overweight children were rated lower on energy, optimism, compliance, concentration, perseverance, and self-confidence, and higher on egocentricity, irritability, and anxiety. These findings suggest possible mechanisms to investigate in future research relating personality to childhood obesity. © 2015 World Obesity.

    Full Text Available Abstract Background Socioeconomic differences in oral health have been reported in many countries. Poverty and social exclusion are two commonly used indicators of socioeconomic position in Latin America. The aim of this study was to explore the associations of poverty and social exclusion with dental caries experience in 12-year-old children. Methods Ninety families, with a child aged 12 years, were selected from 11 underserved communities in Lima (Peru, using a two-stage cluster sampling. Head of households were interviewed with regard to indicators of poverty and social exclusion and their children were clinically examined for dental caries. The associations of poverty and social exclusion with dental caries prevalence were tested in binary logistic regression models. Results Among children in the sample, 84.5% lived in poor households and 30.0% in socially excluded families. Out of all the children, 83.3% had dental caries. Poverty and social exclusion were significantly associated with dental caries in the unadjusted models (p = 0.013 and 0.047 respectively. In the adjusted model, poverty remained significantly related to dental caries (p = 0.008, but the association between social exclusion and dental caries was no longer significant (p = 0.077. Children living in poor households were 2.25 times more likely to have dental caries (95% confidence interval: 1.24; 4.09, compared to those living in non-poor households. Conclusion There was support for an association between poverty and dental caries, but not for an association between social exclusion and dental caries in these children. Some potential explanations for these findings are discussed.

    Some studies suggest that simultaneous or sequential cochlear implantation in a short period of time offers additional benefits. There is controversy regarding the existence of an age limit after which a second implantation offers less benefit for the acquisition of communication skills. The objectives of this study were to confirm that sequential cochlear implantation offers benefits compared to unilateral implantation and to study whether, at 12 years of age, there are significant differences regarding the age at the time of the second implantation. Descriptive and observational study of a population of 12-year-old children carrying cochlear implants (n=69). A liminal pure tone audiometry and an open-field verbal discrimination test (disyllables, common phrases in an open context, with and without noise) were conducted to evaluate audiological benefits. Verbal discrimination results were better among patients who had been implanted before the age of 2 years, although the differences were not statistically significant (P>.5). Children who had received bilateral cochlear implants before the age of 2 years and with a period less than 4 years between both implants presented better verbal discrimination percentages (Pcochlear implantation with a short period between both implants provided significant benefits regarding intelligibility. There seem to be a specific age and interimplant period, after which the auditory benefit on the first implant becomes reduced. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    To assess short- and long-term effects of rapid maxillary expansion (RME) on nasal flow in young children. Since RME has been reported to positively influence nasal obstruction in subjects with respiratory problems by reducing nasal resistance, a similar efficacy of RME could be expected in children with deciduous and/or mixed dentition who are affected by maxillary constriction and nasal obstruction from a different cause. Prospective study of children younger than 12 years, with different grades of malocclusion and oral breathing. Data included active anterior rhinomanometry in both the supine and orthostatic positions, as well as radiographic cephalometric measurements. Tertiary care university hospital. Data were prospectively collected from 2005 to 2007. Nasal flow and resistance were measured in 65 children younger than 12 years, with mixed or deciduous dentition and different grades of malocclusion and oral breathing. Efficacy of RME for resolution of maxillary constriction. After RME, an improvement of nasal flow and resistance has been recorded in patients, in the supine position, who presented both anterior and posterior obstruction. Less notable changes were shown in isolated forms of obstruction and in the orthostatic position. In cases of maxillary constriction and nasal airway obstruction, RME has proved to be efficient for the improvement of nasal respiration in children via a widening effect on the nasopharyngeal cavity.

    This study investigated whether parenting behaviors differed between parents of 68 clinically anxious children and 106 healthy control children aged 4-12 years. The effects of parent gender, child gender and child age on parenting were explored. Mothers and fathers completed a questionnaire to assess parenting behaviors in for children hypothetically anxious situations. Results showed that parents of clinically anxious children reported more anxiety-enhancing parenting (reinforcement of dependency and punishment) as well as more positive parenting (positive reinforcement). For the clinical sample, fathers reported using more modeling/reassurance than mothers, and parents reported using more force with their 4-7-year-olds than with their 8-12-year-olds. No interaction effects were found for child gender with child anxiety status on parenting. Results indicate that for intervention, it is important to measure parenting behaviors, and to take into account father and mother differences and the age of the child. Copyright © 2015 Elsevier Ltd.

    Asthma, which is characterized by mouth breathing and by the use of drugs for its treatment, affects between 1 and 30% of children and adolescents. There are only few studies reporting its impact on the oral cavity. To find out the most common asthma-associated repercussions in 6 to 12-year-old children. Cross-sectional, comparative, analytical study carried out in 2 primary schools from Coclique, Veracruz, Mexico, in 6 to 12-year-old children. The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire for parents was used. In a population of 409 children, a prevalence of asthma of 6.84% (n = 28) was found, which was higher in males (15, 54%); boys aged 6, 7 and 11 years and girls aged 8, 9 and 10 years were most affected. Risk factors for oral manifestations were acidic pH (OR = 170), caries (OR = 4.29), anterior open bite (OR = 66.78), gingivitis (OR = 9.75), atypical swallowing (OR = 15.70) and high-arched palate (OR = 45.60). Children with chronic conditions such as asthma require an oral and dental preventive program as part of their interdisciplinary care.

  2. Results and Implications of a 12-Year Longitudinal Study of Science Concept Learning

    This paper describes the methods and outcomes of a 12-year longitudinal study into the effects of an early intervention program, while reflecting back on changes that have occurred in approaches to research, learning and instruction since the preliminary inception stages of the study in the mid 1960s. We began the study to challenge the prevailing consensus at the time that primary school children were either preoperational or concrete operational in their cognitive development and they could not learn abstract concepts. Our early research, based on Ausubelian theory, suggested otherwise. The paper describes the development and implementation of a Grade 1-2 audio tutorial science instructional sequence, and the subsequent tracing over 12 years, of the children's conceptual understandings in science compared to a matched control group. During the study the concept map was developed as a new tool to trace children's conceptual development. We found that students in the instruction group far outperformed their non-instructed counterparts, and this difference increased as they progressed through middle and high school. The data clearly support the earlier introduction of science instruction on basic science concepts, such as the particulate nature of matter, energy and energy transformations. The data suggest that national curriculum standards for science grossly underestimate the learning capabilities of primary-grade children. The study has helped to lay a foundation for guided instruction using computers and concept mapping that may help both teachers and students become more proficient in understanding science.

    Window replacement is a key method of reducing childhood lead exposure, but the long-term effectiveness has not been previously evaluated. Windows have the highest levels of interior lead paint and dust compared to other building components. Our objective was to conduct a follow-up study of residential window replacement and lead hazard control 12 years after homes were enrolled in an evaluation of the HUD Lead Hazard Control Grant Program, sampling settled lead dust in housing in four cities (n=189 homes). Previous work evaluated lead hazard controls up to 6 years after intervention using dust lead measurements and two years after intervention using both dust and blood lead data. But the earlier work could not examine the effect of window replacement over the longer time period examined here: 12 years. The individual homes were assigned to one of three categories, based on how many windows had been replaced: all replacement, some replacement, or non-replacement. Windows that were not replaced were repaired. We controlled for covariates such as site, housing condition, presence of lead paint, and season using longitudinal regression modeling. Adjusted floor and sill dust lead geometric mean dust lead loadings declined at least 85% from pre-intervention to 12 years after the intervention for homes with all replacement windows, some windows replaced and no windows replaced. Twelve years after intervention, homes with all replacement windows had 41% lower interior floor dust lead, compared to non-replacement homes (1.4 versus 2.4 μg/ft2, plead was 51% lower (25 versus 52 μg/ft2, p=0.006) while controlling for covariates. Homes with some windows replaced had interior floor and window sill dust lead loadings that were 28% (1.7 versus 2.4 μg/ft2, p=0.19) and 37% (33 versus 52 μg/ft2, p=0.07) lower, respectively, compared to non-replacement homes. The net economic benefit of window replacement compared to window repair (non-replacement) is $1700-$2000 per housing unit

    Dental caries is the most prevalent chronic illness worldwide. In the US dental caries has been described as a "silent epidemic", affecting 58.2 % of 12-15 year-olds, particularly in minority and immigrant groups. Caries is associated with complex yet preventable biological and behavioral factors such as dental plaque and diet, as well as social determinants of health. In developed nations, a higher risk caries has been associated with populations of low socio-economic status (SES), especially in areas with greater income disparity. An island-wide study conducted in Puerto Rico in 1997 revealed a high prevalence of dental caries in 12-year-olds and a significant health disparity between children attending private and public schools. The purpose of the present study was twofold: 1) to estimate caries levels of 12-year-old school Puerto Ricans in 2011; and 2) compare results to data obtained in 1997 to explore any possible change in caries outcomes after a government health insurance (GHI) reform was implemented. In this cross-sectional study, a probability sample of 133 out of 1,843 schools was selected proportional to enrollment size, and stratified by 1997 GHI regions, school type, and gender. Calibrated examiners conducted oral soft tissue and caries examinations. Dental caries prevalence was estimated. Mean Decayed Missing Filled Tooth/Surface (DMFT/S) indices and mean Significant Caries Index (SiC) were calculated and compared retrospectively to data obtained in 1997. The final sample included 1,587 school-enrolled children. About 53 % of participants were female and 77 % attended public schools. Between 1997 and 2011, reductions were observed in caries prevalence (81 to 69 %), mean DMFT scores (3.8 to 2.5), mean DMFS scores (6.5 to 3.9), and mean SiC index (7.3 to 5.6) in both private and public schools, with a more prominent decrease in private schools. Between 1997 and 2011, overall the filled component increased (50 to 67 %), while decayed and missing

    The developmental sequence of attention and executive functions (EFs) was studied by utilizing normative data from four hundred 3- through 12-year-old Finnish children. Data from 10 subtests measuring impulse control and inhibition of irrelevant responses, auditory and visual attention, visual search, planning, and verbal and visual fluency were included. The development proceeded sequentially, from motor inhibition and impulse control to functions of selective and sustained attention, and finally to EFs of fluency. Significant relations between gender and development and between parent education and development were found in several subtests. In a factor analysis, inhibition, auditory attention, visual attention, and the EF of fluency clustered into separate factors. The developmental staging and clustering of functions suggests that, although inhibition, attention, and EFs are highly interrelated cognitive functions, their developmental sequences are separate from one another. The development of basic inhibitory functions precedes the development of more complex functions of selective attention, and EFs continue to develop into adolescence.

    A 12-year-old girl was admitted for abdominal pain and signs of acute kidney injury. Physical examination showed abdominal distension and a tumefaction in the lower abdomen. Laboratory and clinical findings were consistent with acute kidney injury. Abdominal ultrasonography showed an oval mass, which corresponded with hematometrocolpos, and right-sided hydronephrosis. Catheterization followed by cruciate hymenectomy was performed. The patient recovered completely. Imperforate hymen is an obstructive anomaly of the female reproductive tract of unknown etiology that can cause a variety of symptoms. It is a rare, but possible cause of acute kidney injury. Patient history data and genital examination findings are sufficient to establish the diagnosis. Abdominal ultrasonography is the most useful diagnostic modality.

    Full Text Available Proteus syndrome is an exceptionally rare congenital disorder with asymmetrical disproportionate overgrowth that includes any tissue of the body. Most of the patients with Proteus syndrome are generally needed to operate for overgrowths and related deformities. However, pulmonary manifestations such as cystic lung and vertebral abnormalities including kyphoscoliosis can lead to high anesthesia risk. The patients with Proteus syndrome should be evaluated in detail preoperatively, and managed carefully during and after anesthesia. Although up to 200 cases with Proteus syndrome have been reported to date, there are few reports on anesthetic management in such cases. In this paper, we present a Proteus syndrome in a case of 12-year old boy who was succesfully operated for foot reconstruction without any anesthesia-related complication.

    Full Text Available Priapism is caused by an imbalance between penile blood inflow and outflow. There are two types of priapism: low-flow priapism due to venous occlusion and high-flow priapism due to uncontrolled arterial flow to the veins. High-flow priapism most frequently occurs as a result of penile trauma in which the intercavernosal artery disruption causes an arteriocavernosal fistula. It is rarely encountered in the pediatric and prepubertal population. Clinically, it manifests as a painless, prolonged erection after perineal trauma. Treatment ranges from expectant management to open surgical exploration with vessel ligation. We report the successful treatment of high-flow priapism in a 12-year-old prepubertal boy with superselective embolization.

    We report a case of Fournier's gangrene in a 12-year-old boy from St. Boniface Hospital in Fond-des-Blancs, Haiti. Fournier's gangrene, a fulminant necrotizing fasciitis of the penis and scrotum, is a rare and life-threatening infection that requires hospitalization, broad-spectrum antibiotics, and surgical debridement.1-3 It is usually associated with impaired cellular immunity due to systemic disorders such as diabetes and liver disease.4,5 This patient had none of those risk factors, but had severe, longstanding phimosis, for which circumcision had been recommended many years before. This case illustrates how lack of access to basic surgical care for an easily treatable condition leads to advanced presentation of a severe disease process.

The onset was preceded by a sore throat 4 weeks prior, but no recent immunizations and no sick contacts. He began having problems "catching his toes" for 2 weeks. He had no visual complaints and no bowel or bladder incontinence. He had no recent travel and there were no heavy metal or solvent exposures. He had no prior medical history and he was on no prescription medications. Developmentally, he was on track and had just successfully completed fifth grade. However, he was reported to be behaviorally oppositional, especially regarding his diet which was restricted to beef jerky, yogurt from a squeeze tube, and fruit drinks. Family history included diabetic peripheral neuropathy in his mother, idiopathic peripheral neuropathy in his maternal grandfather, and left lower extremity neuropathy from trauma in his father. There was no known family history of recurrent pressure palsies or cardiac problems.

    We report a 12-year-old boy who presented with abdominal pain and who was found to have an aneurysm of the abdominal aorta (AAA). The patient was born from a quadruplet pregnancy induced by in vitro fertilization. Postnatal transient respiratory distress required assisted ventilation that had been monitored by two consecutive umbilical arterial catheters (UAC). AAA is a rare condition in childhood. Infection and/or trauma are known to be the most frequent causes. Most of the reported cases have occurred in children in whom a UAC had been placed during the neonatal period. In this patient the delay between UAC placement and diagnosis was considerable. At the time of this report the patient had remained well during a follow-up of 8 years after treatment. (orig.)

    Peripheral odontogenic myxoma is a rare odontogenic tumor representing an extra osseous counterpart of central odontogenic myxoma. It is commonly seen in gingiva between the 3rd and 4th decades of life and appears predominantly in females. Compared to central odontogenic myxoma, it is a less aggressive, slow-growing lesion with a low recurrence rate. However, close postoperative follow-up is required because of the unlimited growth potential of incompletely removed lesions. It shares many features with other soft tissue myxoid proliferations occurring in the oral cavity and hence needs to be differentiated from them. Very few cases of peripheral odontogenic myxomas have been reported and, to the best of our knowledge, no case has been reported in a pediatric patient. We present an unusual case of peripheral odontogenic myxoma occurring in a 12-year-old girl located in the anterior mandibular gingiva, with an emphasis on differential diagnosis.

    BACKGROUND: Infective endocarditis (IE) is a complex disease necessitating extensive clinical guidelines. The guidelines from the American Heart Association (AHA) and the European Society of Cardiology (ESC) have been markedly extended during the last 12 years. We examined the evidence base......, P=.02, a 12.2-fold increase). CONCLUSIONS: The number of IE guideline recommendations has increased 6- to 7-fold during the last decade without a corresponding increase in evidence. These results highlight the strong need for more clinical studies to improve the level of evidence in IE guidelines....... for these changes. METHODS: IE guidelines published by AHA and ESC were reviewed. We categorized and combined guidelines into 3 time periods: (1) 2004 (AHA) and 2005 (ESC), (2) 2007 (AHA) and 2009 (ESC), and (3) 2015 (AHA) and 2015 (ESC).

    To describe the habitual transport patterns of 11 to 12-year-old children in Australia, to determine the personal and environmental factors associated with active transport (AT), and to quantify how much AT contributes to overall daily energy expenditure (EE). The participants in this study were 136 children aged 11-12 year olds from eight randomly chosen primary schools in Adelaide, South Australia. Each child recalled their trips on two school days and a non-school day. Mass and stature were measured, and children completed a computerised activity recall and a neighbourhood satisfaction questionnaire. Trips were categorised according to their destination, child and parent dissatisfaction with the neighbourhood, and the gender, socio-economic status (SES), BMI and activity levels of the children undertaking them. These categories, along with the distance to the destination, were used as independent variables in a logistic regression model, with trip mode (passive versus active) as the dependent variable. Children made an average of 1.0 active trips per day, with a median trip length of 0.63 km, while the median total distance covered actively per child per day was 0.61 km. Twenty-six per cent of children did no AT over the three days, and 67% did no AT on a weekend day. Distance was by far the strongest predictor of the likelihood that a trip would be active. Trips made by girls were less likely to be active compared with boys. Trips to the shops were less likely to be active than trips to school. Children's AT accounted for 1.3% of their daily EE. The active transport levels of children were very low. Interventions should focus on making neighbourhoods safer and more accessible to children and should promote bicycle use.

    The objective of this study was to prospectively evaluate the long-term efficacy of rapid maxillary expansion (RME) in a group of children with obstructive sleep apnea (OSA). Thirty-one children diagnosed with OSA were involved in the study. These children had isolated maxillary narrowing and absence of enlarged adenotonsils at baseline. Twenty-three individuals (73% of the initial group) were followed up annually over a mean of 12 years after the completion of orthodontic treatment at a mean age of 8.68 years. Eight children dropped out over time due to either moving out of the area (n = 6) or refusal to submit to regular follow-up (n = 2). Subjects underwent clinical reevaluation over time and repeat polysomnography (PSG) in the late teenage years or in their early 20s. During the follow-up period, eight children dropped out and 23 individuals (including 10 girls) underwent a final clinical investigation with PSG (mean age of 20.9 years). The final evaluation also included computerized tomographic (CT) imaging that was compared with pre- and post-initial treatment findings. Yearly clinical evaluations, including orthodontic and otolaryngological examinations and questionnaire scores, were consistently normal over time, and PSG findings remained normal at the 12-year follow-up period. The stability and maintenance of the expansion over time was demonstrated by the maxillary base width and the distance of the pterygoid processes measured using CT imaging. A subgroup of OSA children with isolated maxillary narrowing initially and followed up into adulthood present stable, long-term results post RME treatment for pediatric OSA.

    Full Text Available Background The causes of obesity in children are multifactorial, including genetics, physiology, metabolism, psychology, socioeconomic status, lifestyle, and culture. Objective To assess for relationships between obesity in 6 to 12-year-old children and maternal nutritional status, maternal education, eating breakfast, eating fast food, physical activity, TV watching, and playing video games. Methods This case-control study included students of Sejahtera Public School aged 6 to 12 years. Questionnaires were distributed to their parents for data on maternal education, eating breakfast, eating fast food, physical activity, TV watching and playing video games. Maternal nutritional status was assessed by one of the researchers. Univariate analysis with Chi–square test was used to assess every risk factor. Those with a P value of <0.25 were subjected to multivariate analysis, performed using multiple logistic regression analysis. Results From June to July 2013, 60 obese children and 60 wellnourished children, as a control group, were enrolled in the study. Obese mothers tended to have obese children [odds ratio/OR 252.48; 95%CI 33.4 to 1908.4]. Children who ate fast food 6–8 times/week, had low physical activity, and watched TV more than 8 hours/week had significantly higher risk for obesity [OR 12.94, 95%CI 1.7 to 100.7; and OR 266.94, 95% CI 7.8 to 9137.7; OR 21.44, 95%CI 2.68 to 171.61; respectively]. Maternal education, eating breakfast, and playing video games were not significant risk factors for childhood obesity. Conclusion Maternal obesity, eating fast food 6-8 times per week, low physical activity and watching TV more than 8 hours/ week are risk factors for childhood obesity.

    To examine the role of genetic and environmental factors on sleep behavior in 12-year-old twins matched for family environment. Population-based twin cohort. Participants were assessed in their home environment. One hundred thirty-two adolescent twins comprising 25 monozygotic (MZ) and 41 dizygotic (DZ) twin pairs; aged 12.2 ± 0.1 y (mean ± standard deviation). N/A. For 2 weeks in their home environment, participants wore a wrist activity monitor and completed a daily sleep diary. Sleep diaries included reports of bedtime, wake time, and estimated sleep onset time. Mean timing, duration, and quality of sleep during the 2 weeks were calculated for each individual and compared within twin pairs. MZ twin correlations were higher than the DZ correlations for total sleep time (MZr = 0.64; DZr = 0.38) and sleep onset latency (MZr = 0.83; DZr = 0.53) and significantly higher for wake after sleep onset (MZr = 0.66; DZr = 0.04) and sleep efficiency (MZr = 0.82; DZr = 0.10). Univariate modeling showed additive genetic factors accounted for 65% of the variance in total sleep time, 83% in sleep onset latency, and 52% and 57% of the variance in wake after sleep onset and sleep efficiency, respectively. A predominant influence of shared environment was found on the timing of sleep (67% for sleep start time, 86% for sleep end time). There is a strong genetic influence on the sleep-wake patterns of 12-year-old adolescents. Genes have a greater influence on sleep initiation and sleep maintenance and a smaller role in sleep timing, likely to be influenced by family environment.

    In November 1999, the Queensland Health (QH) Transition to Practice Nurse Education Program - Intensive Care (TPNEP-IC) was initiated in QH Intensive Care Units (ICUs) across Queensland. This 12-month, state-wide, workplace based education program has set minimum standards for intensive care nursing education and therefore minimum standards for intensive care nursing practice in QH. In the 12 years of operation, 824 nurses have completed TPNEP-IC, 761 achieving academic credit status and 453 utilising this academic credit status to undertake postgraduate study in critical/intensive care nursing at three Queensland universities. These outcomes were achieved through the appointment of nurse educators within ICUs who, through a united and strong commitment to this state-wide approach formed collaborative professional networks, which resulted in the development, implementation and maintenance of the program. Furthermore, these networks enabled a framework of support for discussion and dissemination of evidence based practice, to endorse quality processes for TPNEP-IC and to nurture leadership potential among educators. Challenges to overcome included obtaining adequate resources to support all aspects of the program, gaining local management and administrative support, and embedding TPNEP-IC within ICU culture. The 12 years of operation of the program have demonstrated its long term sustainability. The program is being launched through a new blended learning approach utilising e-learning strategies. To capitalise on the current success, a strong commitment by all stakeholders will be required to ensure the ongoing sustainability of the program.

    Evidence from the literature has shown that people with a lower socioeconomic status enjoy less good health than people with a higher socioeconomic status. The Italian deprivation index (DI) was used with the aim to evaluate the association between the DMFT index and risk factors for dental caries, including city population and DI. The study included 4,305 12-year-old children living in 38 cities classified by demographic size as small, midsize and large. Zero-inflated negative binomial multilevel regression models were used to assess risk factors for DMFT and to address excess of zero DMFT and overdispersion through a Bayesian approach. The difference in the average level of DMFT among children living in cities with different DI quintile was not statistically significant (p = 0.578). The DI and ln(population), included as city-level fixed effects in the two-level variance components model, were not statistically significant. Consuming sweet drinks on average increased the mean DMFT of a susceptible child, while having a highly educated mother reduced it. Unobserved heterogeneity among cities was detected for the probability to be non-susceptible to caries (city-level variance = 0.26 with 95% credibility interval 0.09-0.57), while no territorial effect was found for the mean DMFT of the susceptible children. Our results suggest that the DI and city population did not play a role in explaining between-city variability. Interventions against social deprivation can be influential on the perception of oral health in Italian 12-year-old children to the extent that they can also affect individual level factors.

    Full Text Available Background Acute leukemia is a malignant, rapidly progressive disease of the bone marrow and blood that most commonly occurs in children. Abnormalities of blood caused by leukemia and also accumulation of leukemic cells in different parts of the oral cavity cause a wide spectrum of oral manifestations. Objectives The current study aimed to estimate the incidence of leukemia among children in Tehran and evaluate oral manifestations of the disease as potential diagnostic markers. Patients and Methods In this retrospective cross-sectional study, medical records of children younger than 12 years referred to Mofid hospital, Ali-Asghar hospital and Children’s medical center from 1997to 2011 were retrieved from the hospital archives and evaluated. Records of 100 patients with leukemia were randomly selected for evaluation. The obtained data were transferred to the questionnaires. Data were analyzed using SPSS version 11.5 and Chi-square test. Results Of the 3,789 children younger than 12 years referred to the hematology department of Tehran pediatric hospitals from 1997 to 2001, 1,372 had acute leukemia, put of which 94% had acute lymphoblastic leukemia and 5% had acute myeloid leukemia. Boys aged 5 - 10 years made up 69% of the acute leukemia cases. The most common oral manifestation was gingival bleeding and petechiae. The most important disease other than leukemia was anemia in the patients. Conclusions The present study highlights the role of dentists to detect oral manifestations of leukemia and their possible role in early diagnosis of patients with the disease.

    The present study focuses on the long-term prognosis of radiographically verified stenosis of the lower lumbar spine. The purpose here was to describe the outcome 12 years after radiographic diagnosis of spinal stenosis and to identify factors predicting disability after operative or conservative treatment. Data were compiled on 75 patients (43 men and 32 women) with changes in functional myelography diagnostic for spinal stenosis. Their mean age at the interview 12 years later was 61 years. The sagittal diameter of the dural sac was measured from baseline myelographs at all intervertebral levels and was corrected for magnification. In the interview, subjective outcome assessment was obtained with a structured questionnaire, and the low-back disorder was scored using the Oswestry disability index. The sagittal diameter of the dural sac was severely stenotic (<7.0 mm) in 32 patients (26 operated), and moderately stenotic (7.0-10.5 mm) in 43 patients (31 operated). The severity of the stenosis significantly predicted disability, even when the effects of age, sex, therapy regimen, and body mass index were adjusted for. For moderate and severe stenosis, the adjusted mean Oswestry indices were 28.4 and 39.1, respectively (p = 0.01). Therapy as such (operative versus nonoperative) did not significantly correlate with later disability. The radiographic severity of lumbar spinal stenosis predicts disability independently of therapy regimen. Randomized clinical trials are needed to establish the indications for surgical and conservative treatment. Radiographic severity of the stenosis should be considered as an effect-modifying or confounding factor in clinical trials and other studies focusing on the outcome of lumbar spinal stenosis.

    Full Text Available Overweight children and childhood obesity are a public health problem in Mexico. Obesity is traditionally assessed using body mass index (BMI, but an excess of adiposity does not necessarily reflect a high BMI. Thus, body composition indexes are a better alternative. Our objective was to generate body composition percentile curves in children from Mexico City. A total of 2026 boys and 1488 girls aged 6 to 12 years old were studied in Mexico City. Body weight, height, and BMI calculation were measured. Total body fat percentage (TBFP was derived from the skinfold thicknesses, and fat mass (FMI and free fat mass indexes (FFMI were calculated. Finally, age- and gender-specifıc smoothed percentile curves were generated with Cole’s Lambda, Mu, and Sigma (LMS method. In general, height, weight, waist circumference (WC, and TBFP were higher in boys, but FFM was higher in girls. TBFP appeared to increase significantly between ages 8 and 9 in boys (+2.9% and between ages 10 and 11 in girls (+1.2%. In contrast, FFM% decreased noticeably between ages 8 and 9 until 12 years old in boys and girls. FMI values peaked in boys at age 12 (P97 = 14.1 kg/m2 and in girls at age 11 (P97 = 8.8 kg/m2. FFMI percentiles increase at a steady state reaching a peak at age 12 in boys and girls. Smoothed body composition percentiles showed a different pattern in boys and girls. The use of TBFP, FMI, and FFMI along with BMI provides valuable information in epidemiological, nutritional, and clinical research.

    Women with a history of preeclampsia have increased risk of cardiovascular disease later in life. However, it is unclear whether early gestational age at preeclampsia onset is associated with higher cardiovascular disease risk. This study aimed to test the association between gestational age at preeclampsia onset (including the early-onset/late-onset preeclampsia distinction) and subclinical atherosclerosis and arterial stiffness in age-matched women 12 years after index pregnancy. Eligible participants were identified in two Danish registries. Main outcome measures were carotid plaque presence, carotid intima-media thickness, aortic pulse wave velocity, and augmentation index adjusted for heart rate. Twenty-four women with previous early-onset preeclampsia, 24 with previous late-onset preeclampsia and 24 with previous normotensive pregnancies were included after matching on age (±2 years) and time since delivery (±1 year). In all outcome measures, the early-onset group had the highest percentage or mean value. In the adjusted analysis, the early-onset group significantly differed from the late-onset group in all outcome measures except aortic pulse wave velocity. The early-onset group also had significantly higher carotid intima-media thickness (average and left) compared with the normotensive group. Gestational age at preeclampsia onset as a continuous variable was significantly associated to both carotid plaque presence and carotid intima-media thickness (average and right). Gestational age at preeclampsia onset is negatively associated with markers of subclinical atherosclerosis 12 years after delivery. Potentially, gestational age at preeclampsia onset might be helpful in directing cardiovascular disease prevention after preeclampsia. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    Full Text Available OBJECTIVE: The aim of this work was the follow-up and evaluation of valve replacement in children under 12 years of age. METHODS: Forty-four children less than 12 years old were underwent valve replacement at INCOR-HCFMUSP between January 1986 and December 1992. Forty (91% were rheumatic, 39 (88.7% were in functional classes II or IV, 19 (43.2% were operated upon on an emergency basis, and 6 (13.6% had atrial fibrillation. Biological prostheses (BP were employed in 26 patients (59.1%, and mechanical prostheses (MP in 18 (40.9%. Mitral valves were replaced in 30 (68.7%, aortic valves in 8 (18.2%, a tricuspid valve in 1 (2.3%, and double (aortic and mitral valves in 5 (11.4 of the patients. RESULTS: Hospital mortality was of 4.5% (2 cases. The mean follow-up period was 5.8 years. Re-operations occurred in 63.3% of the patients with BP and in 12.5% of those with MP (p=0.002. Infectious endocarditis was present in 26.3% of the BP, but in none of the cases of MP (p=0.049. Thrombosis occurred in 2 (12.5% and hemorrhage in one (6.5% of the patients with a MP. Delayed mortality occurred in 5 (11.9% of the patients over a mean period of 2.6 years; four had had BP and one had a MP (NS. Actuarial survival and re-operation-free curves after 10 years were respectively, 82.5±7.7 (SD% and 20.6±15.9%. CONCLUSION: Patients with MP required fewer re-operation, had less infectious endocarditis and lower late mortality rates compared with patients with bioprostheses. The former, therefore, appear to be the best valve replacement for pediatric patients.

    This study examines the selective, sustained, and executive attention abilities of very preterm (VPT) born children in relation to concurrent structural magnetic resonance imaging (MRI) measures of regional gray matter development at age 12 years. A regional cohort of 110 VPT (≤32 weeks gestation) and 113 full term (FT) born children were assessed at corrected age 12 years on the Test of Everyday Attention-Children. They also had a structural MRI scan that was subsequently analyzed using voxel-based morphometry to quantify regional between-group differences in cerebral gray matter development, which were then related to attention measures using multivariate methods. VPT children obtained similar selective (p=.85), but poorer sustained (p=.02) and executive attention (p=.01) scores than FT children. VPT children were also characterized by reduced gray matter in the bilateral parietal, temporal, prefrontal and posterior cingulate cortices, bilateral thalami, and left hippocampus; and increased gray matter in the occipital and anterior cingulate cortices (family-wise error-corrected pmatter in the anterior cingulate cortex (p=.04). Poor executive shifting attention was associated with reduced gray matter in the right superior temporal cortex (p=.04) and bilateral thalami (p=.05). Poorer executive divided attention was associated with reduced gray matter in the occipital (p=.001), posterior cingulate (p=.02), and left temporal (p=.01) cortices; and increased gray matter in the anterior cingulate cortex (p=.001). Disturbances in regional gray matter development appear to contribute, at least in part, to the poorer attentional performance of VPT children at school age. (JINS, 2017, 23, 539-550).

    Extracorporeal lithotripsy does not always provide satisfactory results for the treatment of ureteral stones. Such cases appear to be excellent indications for endocorporeal lithotripsy based on an association of ureteroscopy and laser. To compare the performances of 2 pulsed lasers, the pulsed dye laser (Candela) and solid Q switched laser (HMT), for the treatment of these calculi 161 ureteral stones were treated successively from November 1990 to March 1992 by a combination of ureteroscopy and laser. Endocorporeal lithotripsy was performed in 102 cases with the Candela laser, in 47 with the HMT laser and in 7 with both lasers. With a stable success rate greater than 90%, both lasers demonstrated equivalent performances regardless of the location of the stone along the ureter. However, while stone fragmentation was more rapid with the Candela laser, the HMT laser appeared to be more effective for dark stones (monohydrate calcium oxidate).

    Full Text Available Introduction and objective: Tooth caries is the most prevalent infectious disease in children. The purpose of this study was to assess carries experience indexes and related factors among 7-12 year-old school children in Yasuj, Iran, in 2014. Materials and methods: In the present Cross-sectional and analytical study, using a two-stage random sampling, 460 students from primary schools of Yasuj city and surrounding villages were selected. The children were clinically examined at their school by a professional calibrated dentistry team. Their demographic and socioeconomic status, mouth health behaviors and teeth carries status and consumed nutritional materials were gathered by a questioner and a dental chart. The data were analyzed using inferential statistical methods. The SPSS software version 22 was used to extract the outputs and &alpha=0.05 was considered as the significant level. Results: The dental caries prevalence of deciduous, permanent and total of  two type of dents were  75.2, 41.1 and  89.8 percent, respectively and the dmft, DMFT and dmft+DMFT indexes were 3.57, 0.87, and 4.44, respectively.. The caries prevalence of permanent teeth and DMFT in girls were significantly higher than boys (p=0.046, but the caries prevalence in total of dents in boys was significantly higher than girls ( p=0.32. Furthermore, the dental caries prevalence in permanent teeth and DMFT in children resident in rural areas were significantly higher than those in urban areas (p0.1.  Conclusions: Prevalence and severity score of dental caries among 7 - 12 year-old Yasuj students were higher than the WHO standards. The tooth caries experiences were more prevalent in boys and in children resident in rural areas, increased with age and decreased with BMI and less prevalent in children with higher family socioeconomic status. Tooth brushing and flossing and consuming dairy foods were protective agents in occurring tooth caries in primary school children in

Intravenous urography, performed in 1995, revealed right staghorn calculus and hydronephrosis. Chest X-ray showed markedly restricted lung volume due to severe kyphoscoliosis. In 2000, she was declared unsuitable for anaesthesia due to a lack of venous access and a high likelihood of difficulty in weaning off the ventilator in the postoperative period. In June 2002, she developed anuria (urine output=18 ml/24 h) due to ball-valve-type obstruction by a renal stone at the ureteropelvic junction. Urea: 14.4 mmol/l; creatinine: 236 microl/l. Ultrasound showed right hydronephrosis. Percutaneous nephrostomy was performed. Following relief of urinary tract obstruction, there was postobstructive diuresis (3765 ml/24 h). However, the patient expired 19 days later due to progressive respiratory failure. In this spina bifida patient, who had reached the age of 35 years, severe kyphoscoliosis and lack of vascular access presented insurmountable challenges to implement the desired surgical procedure for removal of stones from a solitary kidney.

    Carbon dioxide (CO2) exchanges between crops and the atmosphere are influenced by both climatic and crop management drivers. The investigated crop, situated at the Lonzée Terrestrial Observatory (LTO, candidate ICOS site) in Belgium and managed for more than 70 years using conventional farming practices, was monitored over three complete sugar beet (or maize)/winter wheat/potato/winter wheat rotation cycles from 2004 to 2016. Continuous eddy-covariance measurements and regular biomass samplings were performed in order to obtain the daily and seasonal Net Ecosystem Exchange (NEE), Gross Primary Productivity, Total Ecosystem Respiration, Net Primary Productivity, and Net Biome Production (NBP). Meteorological data and crop management practices were also recorded. The main objectives were to analyze the CO2 flux responses to climatic drivers and to establish the C budget of the cropland. Crop type significantly influenced the measured CO2 fluxes. In addition to crop season duration, which had an obvious impact on cumulated NEE values for each crop type, the CO2 flux response to photosynthetic photon flux density, vapor pressure deficit and temperature differed between crop types, while no significant response to soil water content was observed in any of them. Besides, a significant positive relationship between crop residue amount and ecosystem respiration was observed. Over the 12 years, NEE was negative (-4.34 ± 0.21 kg C m-2) but NBP was positive (1.05 ± 0.30 kg C m-2), i.e. as soon as all lateral carbon fluxes - dominated by carbon exportation - are included in the budget, the site behaves as a carbon source. Intercrops were seen to play a major role in the carbon budget, being mostly due to the long time period it represented (59 % of the 12 year time period). An in-depth analysis of intercrop periods and, more specifically, growing cover crops (mustard in the case of our study), is developed in a companion poster (ref. abstract EGU2017-12216, session SSS9

    Objectives Among 11–12 year-old girls who received the human papillomavirus (HPV) vaccine, we explored, over the subsequent 30 months: 1) trajectories of knowledge about HPV/HPV vaccines and vaccine-related risk perceptions; 2) whether knowledge and risk perceptions impacted sexual attitudes and sexual experience; and 3) whether mothers, clinicians, and media influenced girls’ risk perceptions, attitudes, and behavior. Methods Girls and mothers (n=25 dyads) completed separate, semi-structured interviews within 2 days of, and 6, 18, and 30 months after, their first HPV vaccine dose. Knowledge, risk perceptions related to HPV and other sexually transmitted infections (STIs), and attitudes about sexual behaviors were assessed. Sexual experience was assessed at girls’ 30 month interviews. Clinicians completed interviews at baseline. Transcribed interviews were analyzed using framework analysis. Results Girls’ baseline knowledge was poor but often improved with time. Most girls (n=18) developed accurate risk perceptions about HPV but only half (n=12) developed accurate risk perceptions about other STIs by 30 months. The vast majority of girls thought that safer sex was still important, regardless of knowledge, risk perceptions, or sexual experience. Girls whose HPV knowledge was high at baseline or increased over time tended to articulate accurate risk perceptions; those who were able to articulate accurate risk perceptions tended to report not having initiated sexual activity. Girls whose mothers demonstrated higher knowledge and/or communication about HPV vaccination tended to articulate accurate risk perceptions, whereas clinicians and media exposure did not appear to influence risk perceptions. Conclusions Higher knowledge about HPV vaccines among mothers and girls was linked with more accurate risk perceptions among girls. Clinicians may play an important role in providing education about HPV vaccines to mothers and girls. PMID:26116249

  6. Balloon-borne radiometer measurements of Northern Hemisphere mid-latitude stratospheric HNO3 profiles spanning 12 years

    2007-12-01

    Full Text Available Low-resolution atmospheric thermal emission spectra collected by balloon-borne radiometers over the time span of 1990–2002 are used to retrieve vertical profiles of HNO3, CFC-11 and CFC-12 volume mixing ratios between approximately 10 and 35 km altitude. All of the data analyzed have been collected from launches from a Northern Hemisphere mid-latitude site, during late summer, when stratospheric dynamic variability is at a minimum. The retrieval technique incorporates detailed forward modeling of the instrument and the radiative properties of the atmosphere, and obtains a best fit between modeled and measured spectra through a combination of onion-peeling and optimization steps. The retrieved HNO3 profiles are consistent over the 12-year period, and are consistent with recent measurements by the Atmospheric Chemistry Experiment-Fourier transform spectrometer satellite instrument. We therefore find no evidence of long-term changes in the HNO3 summer mid-latitude profile, although the uncertainty of our measurements precludes a conclusive trend analysis.

    This paper summarizes a series of analyses of clustered, sequential activity/location data collected by Harvard University for 160 children aged 7-12 years in Southern California (Geyh et al., 2000). The main purpose of the paper is to understand intra- and inter-variability in the time spent by the sample in the outdoor location, the location exhibiting the most variability of the ones evaluated. The data were analyzed using distribution-free hypothesis-testing (K-S tests of the distributions), generalized linear modeling techniques, and random-sampling schemes that produced "cohorts" whose descriptive statistical characteristics were evaluated against the original dataset. Most importantly, our analyses indicate that subdividing the population into appropriate cohorts better replicates parameters of the original data, including the interclass correlation coefficient (ICC), which is a relative measure of the intra- and inter-individual variability inherent in the original data. While the findings of our analyses are consistent with previous assessments of "time budget" and physical activity data, they are constrained by the rather homogeneous sample available to us. Owing to a general lack of longitudinal human activity/location data available for other age/gender cohorts, we are unable to generalize our findings to other population subgroups.

    The aim of this ecological study was to analyze to what extent World Health Organization goals were met in relation to dental caries in 2000 in Minas Gerais State, Brazil, identifying factors associated with variation in DMFT and the occurrence of DMFT children and in the percentage of caries-free 5-year-olds. Secondary data from different sources were used. Linear regression and multiple logistic regression techniques were applied to the analysis of the numerical and dichotomous dependent variables. Socioeconomic and dental services supply/utilization indicators were used as potential explanatory variables. The goals expressed by DMFT < or = 3 at 12 years and a minimum of 50% caries-free 5-year-olds were met by 37% and 9% of the State's municipalities, respectively. In general the dependent variables were associated with socioeconomic level, and no associations were identified with dental care. The results should not be generalized, but they do suggest inequities in oral health and the role played by socioeconomic factors and water fluoridation.

    Full Text Available Introduction: Dental erosion is tooth surface loss caused by chemical processes without bacterial involvement, which can affect children because of various dietary and other lifestyle factors. Aims: The aim of this study was to assess the prevalence of dental erosion in 12-year-old schoolchildren in Lucknow city. Materials and Methods: A total of 212 schoolchildren were selected through multistage cluster random sampling method. A pretested self-administered pro forma was used to record demographic data, medical history, and dietary habits. The clinical examination was done to evaluate dental erosion of children using dental erosion index by O'Sullivan. Descriptive analytical tests were used including distribution of erosion, its extent and severity. The findings were compared across the study participants using Chi-square test. Results: The overall prevalence of dental erosion was 34.12% with no significant sex difference. Dental erosion was significantly related to the frequency of consumption of fruit juices (67.07% followed by carbonated drinks (64.47%. In most of the cases, more than half of their surfaces were diagnosed as affected by erosion (26.25% central incisors, 4.83% lateral incisors. Conclusions: Dental erosion among the study group was found to be 34.12%, providing evidence that dental erosion is becoming a significant problem in Lucknow schoolchildren.

    Full Text Available Idiopathic central serous chorioretinopathy (CSC typically affects middle-aged males. To date, only one case of idiopathic CSC in a prepubertal subject has been reported. Atypical idiopathic CSC presentation may be challenging to diagnose. Exclusion of secondary causes of serous retinal detachment (SRD is warranted. We describe the atypical case of a 12-year-old female with a circumscribed SRD that resolved spontaneously and with fluorescein angiography (FA findings that were compatible with idiopathic CSC. Optical coherence tomography (OCT and systemic assessment were performed to exclude other etiologies. FA demonstrated multiple focal leaks in early phases, with subretinal leakage and pooling in late phases. OCT showed a localized circumscribed retinal detachment. Complete blood count was within normal limits. Serum cortisol was normal (22.1 µg/dl and mean arterial blood pressure was 100/60 mm Hg, thereby excluding secondary causes of CSC. This is the second reported case of idiopathic CSC in a prepubertal female and the first one documented by FA and OCT, as well as other studies to exclude secondary causes. Albeit rare, idiopathic CSC should be considered in the differential diagnosis of SRD in this (prepubertal age group, after excluding secondary ocular or systemic etiologies.

    Full Text Available This study examines the effects of the sport migration that occurred over a 12 year period in the secondary sport of basketball in the Czech Republic, in terms of its effect on the popularity of the sport within the culture. The factors of fan attendance and youth membership are isolated and measured quantitatively, using multi-level analysis within teams, between teams and at a federation level. The study was carried out in order to measure the effect of the use of immigrant athletes from an individual team management perspective and from a league growth perspective. It was found that while foreigners displace national athletes, fans were attracted to the use of foreigners and youth were attracted to play the game. The use of foreigners had the most significant correlations at the between team level to home attendance and final placement in the league. Multi-level analysis was used to show that the use of foreigners can be a facilitator for federations and team management to build the popularity of secondary sports in a culture, with certain limitations. This quantitative study of a secondary sport is an addition to the majority of the literature on sport migration, which has been largely conducted on primary sports from a qualitative, sociological perspective.

    Research projects now rely on an array of different channels to increase impact, including high-level scientific output, tools, and equipment, but also communication, outreach, and educational activities. This paper focuses on education for children aged 5-12 years and presents activities that aim to help them (and their teachers) grasp some of the complex underlying issues in environmental science. More generally, it helps children to become familiarized with science and scientists, with the aim to enhance scientific culture and promote careers in this field. The activities developed are focused on rainfall: (a) designing and using a disdrometer to observe the variety of drop sizes; (b) careful recording of successive dry and rainy days and reproducing patterns using a simple model based on fractal random multiplicative cascades; and (c) collaboratively writing a children's book about rainfall. These activities are discussed in the context of current state-of-the-art pedagogical practices and goals set by project funders, especially in a European Union framework.

    Full Text Available Calcinosis cutis is an uncommon disorder caused by an abnormal deposit of calcium phosphate in the skin in various parts of the body. Four main types of calcinosis cutis have been recognized according to etiology: associated with localized or widespread tissue changes or damage (dystrophic calcification, that associated with an abnormal calcium and phosphorus metabolism (metastatic calcification, not associated with any tissue damage or demonstrable metabolic disorder (idiopathic calcification, and Iatrogenic. Very few cases of idiopathic calcinosis cutis are reported in early childhood in the literature. We report one such case of idiopathic calcinosis cutis over elbow in a 12-year-old female child. Histological examinations of the lesions resected in this case reveal calcium deposits in the dermis, surrounded by foreign body giant cells. Idiopathic calcinosis cutis is a rare phenomenon and occurs in the absence of known tissue injury or systemic metabolic defect. It is important to delineate it from other calcification disorders for further plan of management. Medical therapy in calcinosis cutis is of limited benefit in pediatric age group and poses a challenging problem of postsurgical management.

    The aim of this study was to establish orthodontic treatment need according to the Dental Aesthetic Index (DAI) and Aesthetic Component (AC) and Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and to determine its association with gender among Saharan schoolchildren. The study was carried out in accordance with World Health Organization (WHO) recommendations for oral health surveys at 12 years of age. The sample comprised 248 Sahrawi children (135 girls and 113 boys) living in refugee camps in Tindouf, Algeria. None of the children had previously received any orthodontic treatment. A chi-square test was used to analyse the IOTN results by gender, and a Student's t-test was employed for the DAI results. The mean DAI was 23.32 with a standard deviation of 6.05, 4 percent with a very severe and 9.2 per cent with severe malocclusion. Orthodontic treatment need was 16.1 and 2.0 percent, respectively, according to grades 4 and 5 of the IOTN DHC, 13.7 percent according to the IOTN AC, and 28.6 percent according to the modified IOTN (IOTN DHC grades 4-5 and/or IOTN AC grades 8-10). There were no statistically significant differences by gender. The orthodontic treatment need of Western Saharan schoolchildren is similar to that reported by many recent studies in European and in Sub-Saharan countries.

    The treatment of metacarpophalangeal destruction by rheumatoid arthritis is an indication for arthroplasty, the swanson spacer is one of the options. The flexible silicone spacer may be implanted with or without titanium guide sleeves ("grommets"). However, the imaginary abrasion protection for the silicone grommets may in turn lead through micro-movements to wear. A 69 years old female patient suffering from rheumatoid arthritis for 30 years is presented. 12 years ago swansen spacers were implanted to metacarpo-phalangeal joints 2 -5 of the right hand. Due to pain, limited movement and swelling at the volar MCP joints she presented at our clinic. Volar synovectomy of the 3rd ray of the right hand was performed, the A2 ring band could be spared. There was massive metallosis induced by wear of the grommets in the third volar tendon sheath, the other flexors were free of metallosis. These results show that in synovitis after swanson spacer implantation using grommets the differential diagnosis of metallosis must be included and complete synovectomy is the treatment of choice.

    To investigate the prevalence of oral lichen planus in patients younger than 18 years, referred to a dermatology centre in Iran during 2002-2014. Lichen planus is a chronic inflammatory, immune-mediated disease that could affect the oral mucosa and is a pre-cancerous condition. The disease usually develops in middle age with female predominance and is rare in children. In this retrospective study, cases with definitive histopathologic diagnosis of lichen planus, over a 12-year period from 2002 to 2014 from a dermatologic hospital archive were evaluated. The prevalence of both cutaneous and oral lichen planus, the male:female ratio and site of involvement were calculated using SPSS version 21. Thirty-six of 564 patients younger than 18 years old diagnosed with lichen planus. Two females (0.4%) had oral lichen planus. One patient had erosive, and one had bullous, oral lichen planus. Oral lichen planus had a very low frequency in Iranian population younger than 18 years old, identifying these patients is recommended for long-term follow-up.

    Neck pain in the pediatric population has a broad differential diagnosis, ranging from benign to imminently life-threatening causes. Trauma and infection represent the most common etiologies of pediatric neck pain in the pediatric emergency department (PED) setting. Malignancy, though a rare cause of pediatric neck pain, is important to consider in patients with acquired torticollis or focal neurologic signs. We describe the case of a previously healthy 12-year-old female who presented to the PED with neck pain radiating down her upper extremities. The physical examination revealed diminished strength in her upper extremities compared to her lower extremities. Further evaluation revealed lymphadenopathy in the cervical and mediastinal areas and an epidural tumor in the cervical spinal column. The ultimate diagnosis was Hodgkin lymphoma presenting in an unusual manner with cervical spinal cord compression. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Neck pain is a common chief complaint among pediatric patients in the emergency setting. This case of spinal cord compression caused by malignancy illustrates the necessity of detailed spinal imaging in patients with neck pain and "red flag" signs, including but not limited to an abnormal neurologic examination.

    Full Text Available Introduction: Asthma is a growing public health problem affecting over 300 million people worldwide. Asthmatic children have an altered immune response and a high tendency to mouth breathing especially during an episode of rhinitis or an attack thus predisposing them to serious oral health problems. Aim: This study aims to assess oral health status of asthmatic children aged 6–12. Materials and Methods: A cross-sectional study was conducted among 450 asthmatic children aged 6–12 years in Lucknow, asthmatic children were chosen from pediatric department of major hospitals. Gingival index (GI, oral hygiene index-simplified (OHI-S, and dentition status and treatment need of World Health Organization oral health survey pro forma (1997 were used to assess oral health status. ANOVA, Chi-square test, and descriptive statistics were carried out. SPSS 16 was used for the data analysis. Results: Mean dynamical mean-field theory (DMFT was 2.98 ± 1.52 and 3.05 ± 1.60, mean GI score was 1.55 ± 0.52 and 1.53 ± 0.42 and mean OHI-S was 2.59 ± 0.68 and 2.48 ± 0.77 among the male and female asthmatic children. Conclusion: Female asthmatic children had higher mean DMFT score, but lower mean GI score and oral hygiene score than male children in comparison and also they had a compromised oral hygiene status.

    Since its inception 12 years ago, a large, independent OPO experienced a 631% growth in the number of organ donors. These increases in organ recovery were achieved initially through successful mergers, and later, following the mergers, through focused management, OPO organizational development, and hospital marketing and system development. The cumulative percentage increases beginning in 1987 resulted in the OPO achieving 27.2 donors per million population. In 1996 a system of routine notification of all hospital deaths was implemented and a 24-hour communications center was operated. After 3 full years of routine notification, 73% of all deaths were called to the OPO, resulting in the following increases: total referrals, 691%; organ referrals, 41%; organ donors, 16%; bone donors, 149%; skin donors, 123%; and heart valve donors, 78%. The 16% increase in organ donors was twice the national growth rate and significantly more than the 2% growth experienced by the OPO in the year preceding the implementation of routine notification. The OPO has demonstrated sustained growth over the past decade in a time when erosion of donor recovery levels is always a possibility and frequently a reality for many OPOs.

    Full Text Available Objective. To identify dental pain prevalence and associated factors in Mexican schoolchildren. Methods. This cross-sectional study included 1,404 schoolchildren aged 6 to 12 years from public schools in the city of Pachuca de Soto, Hidalgo, Mexico. Data were collected through a questionnaire that addressed sociodemographic and socioeconomic factors, eating and dental hygiene habits, and behavior variables. The dependent variable was self-reported dental pain in the 12 months prior to the survey. Data were analyzed using nonparametric statistics and a binary logistical regression model. Results. Dental pain prevalence among the studied children was 49.9%. The variables associated in the final model (p<0.05 were younger mother’s age, higher socioeconomic level, absence of an automobile in the home, fried food, fruit intake, lower tooth brushing frequency, never having used mouthwash or not knowing about it, and parents/guardians with regular to high levels of knowledge about oral health and a regular or good/very good perception of their child’s oral health. Conclusions. One in two children in the study had experienced dental pain in the twelve months prior to the survey. The association of socioeconomic variables with dental pain suggested inequalities among the children in terms of oral health.

    To study the relationship between impulsivity and sleep disorders in children. A total of 1 736 children at ages of 6 to 12 years were randomly sampled from five districts of Changsha. Their parents completed the questionnaires about children's sleep conditions and behaviors (using Barratt Impulsiveness Scale 11th version). Five hundred and fifty-four children (31.9%) had sleep disorders. The incidence of sleep disorders in boys was significantly higher than that in girls (35.4% vs 28.3%; P<0.01). The scores of attentional, motor, and non-planning impulsiveness factors as well as the total score of Barratt Impulsiveness Scale in children with sleep disorders were significantly higher than those in children without (P<0.01). The incidence of daytime sleepiness (35.9%) in children with sleep disorders was significantly higher than that in children without (24.7%; P<0.01). The scores of attentional, motor, and non-planning impulsiveness factors increased with the grade of sleep disorders, and reached a peak at the fifth grade. The children with frequent sleep snoring showed higher scores of above three impulsiveness factors than children without sleep snoring or having rare snoring (P<0.01). Sleep disorders are associated with impulsivity in children. It is thus essential to pay close attentions to children's sleep for children with relatively high impulsiveness.

    Objectives: The present study was conducted with an aim to assess the caries profile of 12 year old Indian children using Cariogram. Study design: Hundred children were interviewed to record any illness, oral hygiene practices and fluoride exposure after obtaining a three day diet diary. Examination was done to record plaque and dental caries status. Stimulated saliva was collected and salivary flow rate, salivary buffering capacity, Streptococcus mutans and Lactobacillus were assessed. The information obtained was scored and Cariogram was created. Differences between mean decayed, missing and filled teeth ( DMFT) and Cariogram risk groups were assessed using ANOVA. Spearman Correlation coefficients were used to explore correlation among Cariogram scores and individual variables. Results: It was found that 21, 45, 21 and 13 children had 0-20%, 21-40%, 41-60% and 61-100% chance of avoiding caries respectively in future. Significant correlation was observed between cariogram score and DMFT, diet content, diet frequency, plaque scores, Streptococcus mutans counts and fluoride programme. Conclusions: Cariogram model can identify the caries-related factors that could be the reasons for the estimated future caries risk, and therefore help the dentist to plan appropriate preventive measures.

    OBJECTIVE: Observed racial disparities in child safety seat use have not accounted for socioeconomic factors. We hypothesized that racial differences in age-appropriate restraint use would be modified by socioeconomic status and child passenger safety information sources. METHODS: A 2-site, cross-sectional tablet-based survey of parents seeking emergency care for their 1- to 12-year-old child was conducted between October 2011 and May 2012. Parents provided self-report of child passenger safety practices, demographic characteristics, and information sources. Direct observation of restraint use was conducted in a subset of children at emergency department discharge. Age-appropriate restraint use was defined by Michigan law. RESULTS: Of the 744 eligible parents, 669 agreed to participate and 601 provided complete responses to key variables. White parents reported higher use of car seats for 1- to 3-year-olds and booster seats for 4- to 7-year-olds compared with nonwhite parents. Regardless of race, restraint use compared with nonwhite parents, controlling for education, income, information sources, and site. There was substantial agreement (82.6%, κ = 0.74) between parent report of their child’s usual restraint and the observed restraint at emergency department discharge. CONCLUSIONS: Efforts should be directed at eliminating racial disparities in age-appropriate child passenger restraint use for children <8 years. Booster seat use, seat belt use, and rear seating represent opportunities to improve child passenger safety practices among older children. PMID:24420814

The changes in the age borders and childhood structure along with their causes are demonstrated. The childhood crisis is described, its place in the child’s development process identified. The author emphasizes the visible discord between the worlds of adults and children: being less involved in upbringing process nowadays, adults appear to be less exact in their attitude to children; their demands lack clearness and specificity. Both teachers and adults demonstrate helplessness and aloofness, which reflects in children’s consciousness and their attitude to adults, and results in the lost sense of responsibility, infantilism, egoism and moral emptiness of growing generation.

    Full Text Available Introduction Tachycardia-induced cardiomyopathy (TIC is a ventricular dysfunction secondary to chronic and persistent tachycardia that can regress partially or completely following heart rate normalization. Paroxysmal atrial tachycardia and permanent junctional reciprocating tachycardia are two types of frequent arrhythmias that can cause cardiomyopathy in children. Case Presentation A 12-year-old child with obesity (body mass index > 26.8 was admitted with fatigue, pallor and tachypnea to the clinic. He had palpitation for the past 24 hours. On the cardiac auscultation, holosystolic 2/6 murmur was heard in the apex as well as gallop rhythm. Electrocardiogram revealed heart rate of 150 - 160 bpm and negative P waves in II, III and AVF leads. The echocardiography revealed dilated cardiomyopathy with an ejection fraction of 30%. Conclusions Diagnosis of tachycardia-induced cardiomyopathy in children is important, since appropriate treatment improves the prognosis. Every child with recurrent and persistent palpitation with the first episode of congestive heart failure should be evaluated for tachycardia- induced cardiomyopathy.

    This study focused on the relations between performance on a three-choice probability-learning task and conceptions of probability as outlined by Piaget concerning mixture, normal distribution, random selection, odds estimation, and permutations. The probability-learning task and four Piagetian tasks were administered randomly to 100 male and 100 female, middle SES, average IQ children in three age groups (5 to 6, 8 to 9, and 11 to 12 years old) from different schools. Half the children were from Middle Eastern backgrounds, and half were from European or American backgrounds. As predicted, developmental level of probability thinking was related to performance on the probability-learning task. The more advanced the child's probability thinking, the higher his or her level of maximization and hypothesis formulation and testing and the lower his or her level of systematically patterned responses. The results suggest that the probability-learning and Piagetian tasks assess similar cognitive skills and that performance on the probability-learning task reflects a variety of probability concepts.

    A 12 year global database of rain-corrected satellite scatterometer surface winds for tropical cyclones (TCs) is used to produce composites of TC surface wind speed distributions relative to vertical wind shear and storm motion directions in each TC-prone basin and various TC intensity stages. These composites corroborate ideas presented in earlier studies, where maxima are located right of motion in the Earth-relative framework. The entire TC surface wind asymmetry is down motion left for all basins and for lower strength TCs after removing the motion vector. Relative to the shear direction, the motion-removed composites indicate that the surface wind asymmetry is located down shear left for the outer region of all TCs, but for the inner-core region it varies from left of shear to down shear right for different basin and TC intensity groups. Quantification of the surface wind asymmetric structure in further stratifications is a necessary next step for this scatterometer data set.

    To report a first case of Terson-like syndrome associated with asphyxiophilic practices in an adolescent. A 12-year-old boy was referred for decreased visual acuity in his right eye. His father had been diagnosed 3 weeks before with subarachnoidal hemorrhage. Fundus examination showed a dense preretinal hemorrhage in the right eye suggestive of Terson syndrome. Angio-magnetic resonance imaging eliminated aneurysm and arteriovenous malformation from the diagnosis. After questioning the boy further, he reported that he had participated in the "scarf game", a very popular (but lethal) asphyxiophilic practice in middle school, some hours before he noticed a sharp drop in the visual acuity of his right eye. After 2 months of follow-up, he recovered 20/20 vision in his right eye. Retinal hemorrhages are quite rare in children. When the cause is not clear (subarachnoidal hemorrhage, arteriovenous malformation, shaken baby syndrome), it must be determined whether the patient has participated in the asphyxiophilic "scarf game" in order to prevent its lethal consequences.

    Full Text Available INTRODUCTION: Oral hygiene is an essential element of health education programs for schoolchildren. AIM: The study aims to assess the skills when conducting oral hygiene of a group of schoolchildren and to conduct training in its rules. MATERIAL AND METHODS: The study covers 30 children aged 6-12 years. The training was conducted by the methods of the visual pedagogy and implementation of the technique “Say, show, do”. The assessment of the oral-hygiene status was held by the simplified oral hygiene index-Greene & Vermillion. RESULTS AND CONCLUSION: The children do not have proper oral hygiene habits. The daily oral care is inadequate. The number of cleaned tooth surfaces during oral hygiene practice is small. Children have no developed proper oral hygiene skills, and brush only the vestibular surfaces of the teeth (80%, 13.3% the vestibular and the occlusal, and 6.7% only cover lingual surfaces too. The unsatisfactory oral hygiene status is also a result of using only one type of toothbrush movements. The improvement of children's health knowledge should play key role in correcting their oral hygiene technique.

    Orofacial pain is often difficult to diagnose and treat. However, there have been few reports on the clinical observation of dental patients with orofacial pain. We retrospectively investigated the characteristics of 221 dental patients who had suffered from persistent orofacial pain. Data were collected from the outpatient medical records in our clinic over the past 12 years. More than half of the patients (53.8%) had suffered with pain for more than 6 months from pain onset until the first visit to our clinic. The main diagnoses were neuropathic pain (30.3%), myofascial pain (23.5%), psychogenic pain (20.4%), odontogenic toothache (17.2%), and others (7.7%) such as temporomandibular disorders and glossitis. The treatments included pharmacotherapy, splint therapy, and others such as nerve block, dental treatment, physiotherapy, and/or psychotherapy. Excluding the patients (52 of 221 initially enrolled patients) with unknown responses to treatment, 65.7% showed remission or a significant improvement in pain in response to treatment. Although only a small group of patients had odontogenic toothache, the rate of improvement was highest for this disorder. In conclusion, early consultation with a dentist is useful to prevent chronicity of odontogenic pain and to make a differential diagnosis in patients with orofacial pain.

    Full Text Available Background: Fluoride increases tooth resistance to dental caries, but mild toxicity due to excessive ingestion of fluoride can cause dental fluorosis. Drinking water naturally contains fluoride and is a major source of fluoride. In Bushehr port, drinking water is supplied from limestone springs with normal fluoride levels but dental fluorosis is observed. Methods: A total of 95 native school children (between the ages of 10-12 years old were randomly selected from four Bushehr port regions. Dental fluorosis, height and weight were examined. Probable attributing factors of dental fluorosis were also questioned. A 16 to 18 hours urinary fluoride concentration was measured with a fluoride ion selective electrode. Results: Dental fluorosis in four upper incisors was apparent in 52.6 % of the subjects. The urinary fluoride concentration was 2.18 mg/lit. Fluoride concentration in drinking water of schools ranged from 0.41 to 0.58 mg/lit. Forty percent of subjects were caries free. Conclusion: In spite of the normal range of fluoride concentration in the drinking water of Bushehr, dental fluorosis and urinary fluoride concentration are higher than the recommended ranges. Therefore, it is necessary to further investigate the amount and effects of fluoride ingestion in residents of Bushehr province.

    Infective endocarditis (IE) is a complex disease necessitating extensive clinical guidelines. The guidelines from the American Heart Association (AHA) and the European Society of Cardiology (ESC) have been markedly extended during the last 12 years. We examined the evidence base for these changes. IE guidelines published by AHA and ESC were reviewed. We categorized and combined guidelines into 3 time periods: (1) 2004 (AHA) and 2005 (ESC), (2) 2007 (AHA) and 2009 (ESC), and (3) 2015 (AHA) and 2015 (ESC). Number of recommendations, classes of recommendations (I, II, or III), and levels of evidence (LOE) (A, B, or C) were assessed and the changes over time. From period 1 to period 3, we found a statistically significant increase in total number of IE recommendations from 37 to 253 (Pguideline recommendations has increased 6- to 7-fold during the last decade without a corresponding increase in evidence. These results highlight the strong need for more clinical studies to improve the level of evidence in IE guidelines. Copyright © 2017 Elsevier Inc. All rights reserved.

    This thesis is based on a cross-sectional comparative study of dental health, treatment needs and attitudes to dental care in groups of 5- and 12-year-old children from the following eight cities in respective EU countries: Athens-Greece, Berlin-Germany, Cork-Ireland, Dundee-Scotland, Gent-Belgium, Sassari-Italy, Stockholm-Sweden and Valencia-Spain. A total of 3,200 children, 200 in each age group, were clinically examined by well-calibrated dentists, the parents completing a questionnaire on dental habits, parental and children's attitudes to dental care, smoking habits and parental occupations. The results disclosed pronounced differences in dental health and treatment need among the children from the different countries. The Scottish, Italian and German 5-year-olds exhibited the highest values for decayed, missing and filled teeth (dmft). The m component dominated for the Scottish sample, the d component in the Italian and d and f in the German sample. The highest values for DMFT in the 12-year-olds were found in the German, Greek and Italian samples followed by the Swedish sample. The F component dominated in the German and Swedish samples, while D dominated in the Greek and Italian samples. Analyses of the influence of socio-demographic and behavioural factors on the dental health, expressed as dmft/DMFT, showed that the most important factors explaining differences in caries experience were toothache, social class of the family and dental fear in the children. The frequency of similar attitudes (dental fear) in subjects and parents was 50% or higher in all the samples, and the frequency of similar dental attendance patterns in child and parent was 42% or higher in all the samples. For both age groups the proportion of subjects with regular dental attendance habits was highest in the Swedish, Belgian, German and Scottish samples. These findings, together with the high frequency of regular attenders without treatment need in the Swedish 5-year-olds indicate

    The theory, development and results of three quantitative analytical procedures are described and the crystallization experiments in a rotary evaporator are presented. Of the different methods of quantitative X-ray powder diffraction analyses, the internal standard method and a microanalytical technique were identified as the two most useful procedures for the quantitative analysis of urinary calculi. Reference intensity ratios for 6 major stone phases were determined and were used in the analysis of 20 calculi by the internal standard method. Inductively coupled plasma atomic emission spectroscopic (ICP-AES) methods were also investigated, developed and used in this study. Various procedures for the digestion of calculi were tested and a mixture of HNO3 and HC1O4 was eventually found to be the most successful. The major elements Ca, Mg, and P in 41 calculi were determined. For the determination of trace elements, a new microwave-assisted digestion procedure was developed and used for the digestion of 100 calculi. Fluoride concentrations in two stone collections were determined using a fluoride-ion sensitive electrode and the HNO3/HC1O4 digestion prodecure used for the ICP study. A series of crystallization experiments involving a standard reference artificial urine was carried out in a rotary evaporator. The effect of pH and urine composition was studied by varying the former and by including uric acid, urea, creatinine, MgO, methylene blue, chondroitin sulphate A, and fluoride in the reference solution. Crystals formed in these experiments were subjected to qualitative and semi-quantitative X-ray powder diffraction analyses. Scanning electron microscopy of several deposits was also carried out. Similar deposits to those observed in calculi were obtained with the fast evaporator. The results presented suggest that this system provides a simple, yet very useful means for studying the crystallization characteristics of urine solutions.

    Dental caries is one of the most prevalent chronic diseases affecting children in Sub-Saharan Africa. Previous studies show a higher prevalence of dental caries in children from low socio-economic status backgrounds. The purpose of this study was to determine the prevalence of dental caries among 12 year old children in urban and rural areas of Zimbabwe and establish preliminary baseline data. A descriptive cross-sectional study was conducted among 12 year old children at primary schools in Harare and Bikita district. A Pre-tested questionnaire was administered to elicit information from the participants on tooth cleaning, dietary habits and dental experience. Dental caries status was assessed using the DMFT index following World Health Organization (WHO) guidelines. Our results showed a high prevalence of dental caries in both urban (59.5%) and rural (40.8%) children. The mean DMFT in urban and rural areas was 1.29 and 0.66, respectively. Furthermore, our data showed a general lack of knowledge on oral health issues by the participants. There is high prevalence of dental caries among 12 years old school children in both urban and rural areas of Zimbabwe. This calls for early preventive strategies and treatment services. We recommend incorporation of oral health education in the elementary school curricula.

    The strength of adhesion between dental calculus and enamel or dentin surfaces determines the ease with which the calculus can be removed by brushing or professional dental treatment. In this study, we examined the adhesion of canine calculi formed on substrata with different surface free energies (sfe) and roughness by means of scanning electron microscopy. In 4 beagle dogs fenestrated crowns were made on the upper fourth premolars. Subsequently, facings of glass (sfe = 120 mJ. m-2), bovine ...

    To assess the association between weight status and dental caries among 12-year-old Brazilian schoolchildren. This cross-sectional study was carried out in Porto Alegre using a multistage probability sampling strategy to draw a representative sample of schoolchildren attending public and private schools. Data on demographics, socioeconomic status, oral hygiene habits, anthropometrics, and dental caries were collected. Overweight and obesity were defined according to WHO categories for BMI (body mass index)-for-age Z-scores. Survey Poisson regression models were used to assess the association between weight status and dental caries. Estimates were adjusted for gender, socioeconomic status, and brushing frequency. Prevalence ratios (PR), rate ratios (RR) and 95% confidence intervals (95% CI) were reported. One thousand five hundred and twenty-eight of 1837 eligible schoolchildren were examined. Prevalence of overweight and obesity were 22.15% (95% CI = 20.59-23.72) and 13.61% (95% CI = 11.44-15.78), respectively. Caries experience was observed in 55.23% (95% CI = 45.26-65.19) of children. Schoolchildren presented, on average, 1.39 (95% CI = 1.07-1.71) decayed, missing or filled teeth. No significant differences in caries experience or extent were observed among BMI groups. After adjusting for important cofactors, weight status was not associated with caries prevalence (overweight, PR = 0.99; 95% CI = 0.89-1.10; obese, PR = 1.00; 95% CI = 0.87-1.16) or caries extent (overweight, RR = 0.91; 95% CI = 0.74-1.12; obese, RR = 0.86; 95% CI = 0.72-1.04). Our findings indicate that overweight and obese adolescents should not be regarded as at higher risk of dental caries in this population. © 2012 John Wiley & Sons A/S.

    Acute otitis media (AOM) is the most common bacterial infection among young children in the United States. There are limitations and concerns over its treatment with antibiotics and surgery and so effective preventative measures are attractive. A potential preventative measure is xylitol, a natural sugar substitute that reduces the risk of dental decay. Xylitol can reduce the adherence of Streptococcus pneumoniae (S pneumoniae) and Haemophilus influenzae (H influenzae) to nasopharyngeal cells in vitro. This is an update of a review first published in 2011. To assess the efficacy and safety of xylitol to prevent AOM in children aged up to 12 years. We searched CENTRAL (to Issue 12, 2015), MEDLINE (1950 to January 2016), Embase (1974 to January 2016), CINAHL (1981 to January 2016), LILACS (1982 to January 2016), Web of Science (2011 to January 2016) and International Pharmaceutical Abstracts (2000 to January 2016). Randomised controlled trials (RCTs) or quasi-RCTs of children aged 12 years or younger where xylitol supplementation was compared with placebo or no treatment to prevent AOM. Two review authors independently selected trials from search results, assessed and rated study quality and extracted relevant data for inclusion in the review. We contacted trial authors to request missing data. We noted data on any adverse events of xylitol. We extracted data on relevant outcomes and estimated the effect size by calculating risk ratio (RR), risk difference (RD) and associated 95% confidence intervals (CI). We identified five clinical trials that involved 3405 children for inclusion. For this 2016 update, we identified one new trial for inclusion. This trial was systematically reviewed but due to several sources of heterogeneity, was not included in the meta-analysis. The remaining four trials were of adequate methodological quality. In three RCTs that involved a total of 1826 healthy Finnish children attending daycare, there is moderate quality evidence that

    Sedentary behavior and physical activity may be independent risk factors for psychological distress in adolescents, although there is no existing information for children. We examined the cross-sectional association between psychological distress, television and screen entertainment time, and physical activity levels among a representative sample of children aged 4 to 12 years from the 2003 Scottish Health Survey. Participants were 1486 boys and girls (mean age: 8.5 +/- 2.3 years). Parents answered on behalf of children who were required to be present. The parents completed the Strengths and Difficulties Questionnaire and information on television and screen entertainment time, physical activity, and dietary intake of their children. An abnormally high Strengths and Difficulties Questionnaire total difficulties score (20-40) was found in 4.2% of the sample. Approximately 25% of the children were exposed to television and screen entertainment at least 3 hours/day. In general linear models, television and screen entertainment time per week and physical activity levels were independently associated with the Strengths and Difficulties Questionnaire total difficulties score after adjustment for age, gender, area deprivation level, single-parent status, medical conditions, and various dietary intake indicators. There was also an additive interaction effect showing that the combination of high television and screen entertainment time and low physical activity was associated with the highest Strengths and Difficulties Questionnaire score. Higher television and screen entertainment exposure (>2.7 hours/day) alone resulted in a 24% increase in the Strengths and Difficulties Questionnaire score in comparison with lower television and screen entertainment exposure (television and screen entertainment time and low physical activity levels interact to increase psychological distress in young children.

    Driver distraction has been identified as a threat to individual drivers and public health. Motor vehicle collisions remain a leading cause of death for children, yet little is known about distractions among drivers of children. This study sought to characterize potential distractions among drivers of children. A 2-site, cross-sectional, computerized survey of child passenger safety practices was conducted among adult drivers of 1- to 12-year-old children who presented for emergency care between October 2011 to May 2012. Drivers indicated the frequency with which they engaged in 10 potential distractions in the past month while driving with their child. Distractions were grouped in 4 categories: (1) nondriving, (2) cellular phone, (3) child, and (4) directions. Information about other unsafe driving behaviors and sociodemographic characteristics was collected. Nearly 90% of eligible parents participated. Analysis included 570 drivers (92.2%). Non-driving-related and cellular phone-related distractions were disclosed by >75% of participants. Fewer participants disclosed child (71.2%) and directions-related distractions (51.9%). Child age was associated with each distraction category. Cellular phone-related distractions were associated with the child riding daily in the family car, non-Hispanic white, and higher education. Parents admitting to drowsy driving and being pulled over for speeding had over 2 times higher odds of disclosing distractions from each category. Distracted driving activities are common among drivers of child passengers and are associated with other unsafe driving behaviors. Child passenger safety may be improved by preventing crash events through the reduction or elimination of distractions among drivers of child passengers.

    Full Text Available The aims of this study were to describe the anthropometric characteristics, body composition and somatotype of top-level male table tennis players, to compare the first 12 top-level table tennis players with the lower ranked players, and to establish profile chart for total of 112 top-level table tennis players. A total of 112 top-level table tennis players, aged between 9 and 12 years participated in this study. The athletes were divided into three groups, the first 12 (Group A, n=12 and the lower ranked players (Group B, n=47 and (Group C, n=53. In the analysis and comment of the data, One Way Variance Analysis (ANOVA Test were used. There were no significant differences in anthropometric characteristics, body composition and somatotype among the groups. A mesomorph – endomorph somatotype was registered for total of 112 top-level table tennis players. But analysis, taking into account, revealed a balanced ectomorph somatotype for the first 12 players, and a mesomorph - ectomorph somatotype for B group and a mesomorph - endomorph somatotype for C group. Although the influence of anthropometric characteristics on table tennis performance is not clear yet, it seems obvious that a mesomorph - ectomorph predominance can play a decisive role in any sport, On the other hand, high levels of body fat could have a negative effect on sport performance. Regarding to somatotype assessment, balanced ectomorph was the most important component in the first 12 players. In the present study, a greater body fat mass were observed lower ranked players than first 12 players

    According to a recent study it could be shown that more than one third of female high school students and more than 20 % of male students in the age of 14 to 18 years indicated an impaired eating behaviour, expressed as a medium or high risk to develop eating disorders based upon the standardized Eating Attitudes Test (EAT) . The current study tested the prevalence of weight concerns and dieting as an indicator of problematic eating behaviour among younger children. 230 Thuringian female and male students in the 3 (rd) and 4 (th) year (between 8 and 12-years-old) as well as their parents were investigated using standardized and modified instruments. Weight and height were measured directly to determine the Body Mass Index (BMI) that was put into relation to some factors of potential influence such as parents, peers, media and eating behaviours. It could be shown that 42 % of the boys and 53 % of the girls preferred a thin ideal body image; 32 % of the children revealing normal weight expressed the wish to be thinner. 18 % of the boys and 19 % of the girls tried to lose weight at the time of the investigation. Dieting was influenced by the perceived (not actual) dieting behaviour of the parents. The BMI significantly predicted weight concerns: In total, 85 % of the overweight children but also 17 % of the children with normal weight were convinced to be overweight. The girls' eating behaviour was mostly influenced by the peers, the boys' behaviour by criticism of the parents. Generally, a significant influence of the media could be demonstrated.

    The purpose of this study was (1) to evaluate the rates of reverse shoulder arthroplasty (RSA) revisions during a 12-year period, (2) to assess the influence of primary diagnosis and the impact of implant modifications on revisions, (3) to describe surgical management of failed RSA, and (4) to analyze outcomes of patients with minimum 24-month follow-up. A retrospective database review identified primary diagnosis for 1418 patients who underwent RSA from 2000 to 2012. A subgroup of 85 patients required return to the operating room for removal or exchange of components. Indication to reoperate, intraoperative management, and outcomes were reviewed. Indications were grouped into 7 categories: baseplate failure, humeral component dissociation, glenosphere dissociation, glenohumeral dislocation, aseptic humeral loosening, periprosthetic fracture, and infection. During the study, design modifications were made to the baseplate, humeral socket, and glenosphere. Surgical strategies were analyzed through operative reports. Range of motion, American Shoulder and Elbow Surgeons scores, and Simple Shoulder Test scores were collected before and after surgery and compared for 58 patients with 2-year follow-up. Overall revision rate was 6%. Patients undergoing RSA for failed hemiarthroplasty had the highest revision rate (10%). Indications for revision included baseplate failure (2.5%), infection (1.3%), humeral dissociation (0.7%), glenosphere dissociation (0.6%), periprosthetic fracture (0.4%), glenohumeral dislocation (0.4%), and aseptic humeral loosening (0.3%). Baseplate modifications reduced the incidence of baseplate failure to 0.3%. Range of motion and the Simple Shoulder Test and American Shoulder and Elbow Surgeons scores improved. Although revision RSA is challenging, with higher risk for complications compared with primary RSA, patients still exhibit significant clinical improvements.

    Epidemiological information about prevalence of child mental health problems is essential to inform policy and public health practice. This information is weak in many developing countries and those in developmental transition. There have been few such studies in Arab countries and none in Egypt. We conducted a population prevalence study of emotional and behavioural disorders among 1186 6-12 year old children in Minia, Egypt. Data was collected from teachers and parents using the Strengths and Difficulties Questionnaire with a 98 and 91% response respectively. Prevalence of abnormal symptom scores is reported for both parents and teachers. Prevalence of probable psychiatric diagnoses was measured using the SDQ multi-informant algorithm. These prevalences have then been compared to published UK data. The prevalence of emotional and behavioural symptoms was high as reported by both parents and teachers (Abnormal total difficulties: teachers 34.7% (95% CI 32.0-37.5), parents 20.6% (18.2-23.2). Abnormal prosocial scores: teachers 24.9% (22.5-27.5), parents 11.8% (9.9-13.9)) but prevalence of probable psychiatric diagnoses was much lower (Any psychiatric diagnosis 8.5% (6.9-10.5); Emotional disorder 2.0% (1.2-3.0); Conduct disorder 6.6% (5.1-8.3); Hyperactivity disorder 0.7% (0.3-1.4)). Comparison with UK data showed higher rates of symptoms but similar rates of probable disorders. Despite public, professional and political underestimation of child mental health problems in Egypt, rates of symptoms are higher than in developed countries, and rates of disorders are comparable. These findings support greater investment in community and primary care prevention and treatment initiatives.

    Academic achievement by 23 children 10 to 12 years after treatment of Haemophilus influenzae meningitis was assessed using individually administered standardized tests, review of school transcripts, and parent and teacher questionnaires. The children's performance was compared with (1) their own performance in a previous study 6 to 8 years after the illness; (2) the performance of 23 similarly aged siblings in the previous study, a comparison which served to age match subjects and sibling controls; and (3) the performance of 11 of those similarly aged siblings retested in the current study. Subjects scored in the average range on all measures. Scores were comparable to results 4 years previous in four of six academic measures, with minor deterioration in reading single words and decoding nonsense words. There were no differences between subjects in the current study and control subjects from the previous study, except in decoding nonsense words, and no differences between subjects and control subjects in the current study, except in paragraph reading accuracy. Scholastic grade point averages and scores on parent and teacher behavior problem-rating scales showed no group differences. Subjects used more school-based remedial services, although the trend did not achieve statistical significance. Parents reported spending more time with subjects than with control subjects helping with homework. These findings suggest that children who have recovered from meningitis due to H influenzae can maintain scores and grades comparable to their siblings as they progress to middle school. Their academic success may involve more school and family support to compensate for the mild differences in intelligence quotient and neuropsychologic testing found in the previous study.

    Full Text Available The quality of life in patients with chronic problems as the asthma, at present performs major importance in view of the increase of the life expectancy. Nevertheless, often this one does not accompany of conditions biopsicosocial acceptable, that allow to the person to enjoy good emotional condition, as well as the accomplishment of his or her physical, social and school activities. The objective of this study is to know the quality life of the physical, emotional, social, and scholar valuation. Methodology: This study was realized with a number of 124 children sample in ages of 8 to 12 years old with asthma diagnostic.Results: The most damage aspects within quality life dimension were run, work out; lower energy and feeling pain. Emotional aspects were be worried about the future and insomnia, respect to social dimension the problem was children can’t keep in the same condition than others while they are playing; and about school dimension the problem was school absence because of their need of going to the doctor or hospital. Discussion: The aspects of the physical dimension that were more affected to are the follow: run, to do exercise, to have little energy, and to feel pain. Both first ones have relation with the (reported by the Spanish Society of Neumología and Paediatrics (s.f., Where they brought (reported that the children more affected because of the asthma to were those that run and to do exercise. With regard to having little energy and feeling pain, this can owe to persistent accesses of cough, that really they cause weakness and pain in the thoracic box. Conclusions: These results suggest that it is important to stimulate the self-esteem of the children who endure asthma across his participation in an equipment or group.

    Purpose: Although radiosurgery is an accepted treatment method for intracranial arteriovenous malformations (AVMs), its long-term therapeutic effects have not been sufficiently evaluated, and many reports of long-term observations are from gamma-knife facilities. Furthermore, there are few reported results of treatment using only linear accelerator (LINAC)-based radiosurgery (LBRS). Methods and Materials: Over a period of more than 12 years, we followed the long-term results of LBRS treatment performed in 51 AVM patients. Results: The actuarial obliteration rates, after a single radiosurgery session, at 3, 5, 10, and 15 years were 46.9%, 54.0%, 64.4%, and 68.0%, respectively; when subsequent radiosurgeries were included, the rates were 46.9%, 61.3%, 74.2%, and 90.3%, respectively. Obliteration rates were significantly related to target volumes ≥4 cm{sup 3}, marginal doses ≥12 Gy, Spetzler-Martin grades (1 vs other), and AVM scores ≥1.5; multivariate analyses revealed a significant difference for target volumes ≥4 cm{sup 3}. The postprocedural actuarial symptomatic radiation injury rates, after a single radiation surgery session, at 5, 10, and 15 years were 12.3%, 16.8%, and 19.1%, respectively. Volumes ≥4 cm{sup 3}, location (lobular or other), AVM scores ≥1.5, and the number of radiosurgery were related to radiation injury incidence; multivariate analyses revealed significant differences associated with volumes ≥4 cm{sup 3} and location (lobular or other). Conclusions: Positive results can be obtained with LBRS when performed with a target volume ≤4 cm{sup 3}, an AVM score ≤1.5, and ≥12 Gy radiation. Bleeding and radiation injuries may appear even 10 years after treatment, necessitating long-term observation.

    Declines in plant diversity will likely reduce soil microbial biomass, alter microbial functions, and threaten the provisioning of soil ecosystem services. We examined whether increasing temporal plant biodiversity in agroecosystems (by rotating crops) can partially reverse these trends and enhance soil microbial biomass and function. We quantified seasonal patterns in soil microbial biomass, respiration rates, extracellular enzyme activity, and catabolic potential three times over one growing season in a 12-year crop rotation study at the W. K. Kellogg Biological Station LTER. Rotation treatments varied from one to five crops in a 3-year rotation cycle, but all soils were sampled under a corn year. We hypothesized that crop diversity would increase microbial biomass, activity, and catabolic evenness (a measure of functional diversity). Inorganic N, the stoichiometry of microbial biomass and dissolved organic C and N varied seasonally, likely reflecting fluctuations in soil resources during the growing season. Soils from biodiverse cropping systems increased microbial biomass C by 28-112 % and N by 18-58 % compared to low-diversity systems. Rotations increased potential C mineralization by as much as 53 %, and potential N mineralization by 72 %, and both were related to substantially higher hydrolase and lower oxidase enzyme activities. The catabolic potential of the soil microbial community showed no, or slightly lower, catabolic evenness in more diverse rotations. However, the catabolic potential indicated that soil microbial communities were functionally distinct, and microbes from monoculture corn preferentially used simple substrates like carboxylic acids, relative to more diverse cropping systems. By isolating plant biodiversity from differences in fertilization and tillage, our study illustrates that crop biodiversity has overarching effects on soil microbial biomass and function that last throughout the growing season.

    Full Text Available BACKGROUND AND OBJECTIVE Anaemia is one of the most important public health problem among children. The infants, preschool children, adolescents and pregnant women are at highest risk of nutritional anaemia. The aim of this study was to evaluate the prevalence of anaemia and its correlation to age, gender, haemoglobin values and magnitude of anaemia among the children of North East India. METHODS A cross sectional study was conducted in a tertiary care hospital between October 2013 to September 2014. A total of 500 children in the age group 0 to 12 years were enrolled after obtaining written informed consent from the parents. Haemoglobin estimation was done by Sahli’s method using finger prick blood samples. As per WHO recommendation, haemoglobin values below 11 gm/dl was considered anaemic. Statistical data were analysed. RESULTS The overall prevalence of anaemia was 71.2% with males having 5.2%higher than females. The majority of age group comprises 1 to ≤5 years (36.0% and 83.3% of them were anaemic. The highest value of haemoglobin estimated was 14.8 gm/dl with the lowest value of 5.2 gm/dl. The mean haemoglobin level was 10.76±1.21 gm/dl. 53.4% children were mildly anaemic. Both male and female children were affected more with mild anaemia than other types of anaemia. CONCLUSION Our results suggest that all the children should be screened for anaemia irrespective of age and sex as the prevalence is high. Early intervention and appropriate measures should be taken to prevent from anaemia and its associated diseases.

    The nearby (6.5 pc) star HD 219134 was recently shown by Motalebi et al. and Vogt et al. to host several planets, the innermost of which is transiting. We present 27 years of radial velocity (RV) observations of this star from the McDonald Observatory Planet Search program, and 19 years of stellar activity data. We detect a long-period activity cycle measured in the Ca II SHK index, with a period of 4230 ± 100 days (11.7 years), very similar to the 11 year solar activity cycle. Although the period of the Saturn-mass planet HD 219134 h is close to half that of the activity cycle, we argue that it is not an artifact due to stellar activity. We also find a significant periodicity in the SHK data due to stellar rotation with a period of 22.8 days. This is identical to the period of planet f identified by Vogt et al., suggesting that this RV signal might be caused by rotational modulation of stellar activity rather than a planet. Analysis of our RVs allows us to detect the long-period planet HD 219134 h and the transiting super-Earth HD 219134 b. Finally, we use our long time baseline to constrain the presence of longer period planets in the system, excluding to 1σ objects with M{sin}I\\gt 0.36{M}J at 12 years (corresponding to the orbital period of Jupiter) and M{sin}I\\gt 0.72{M}J at a period of 16.4 years (assuming a circular orbit for an outer companion).

    INTRODUCTION & AIMS: The identification of determinants of childhood overweight is crucial to early diagnosis and prevention. The aim of this study was to assess perinatal and parental related risk factors concerning children for having excessive body weight. Cross-sectional study involving 3,101 children participating in the programme "Alimenta su salud" conducted in Castilla-La Mancha (Spain). Anthropometric and sociodemographic data were obtained from a general questionnaire. Analysed factors as potential predictors of childhood overweight were sex, age, birth weight, infant feeding, number of siblings, as well as parental marital status, educational level and obesity. Prevalence of overweight stratified by potential determinants was assessed. Univariate and multivariate logistic regression analyses were used to examine the associations between variables and the likelihood of being overweight. The overweight prevalence (including obesity) was 30.3% in boys and 28.3% in girls, according to the IOTF criteria. Higher rates in younger subjects and some gender differences were observed. Parental obesity was the most important predictive variable for childhood overweight in both sexes and birth weight over 3,500 g in girls (OR 1.8, 95% CI 1.3-2.3). Having one or more siblings (OR 0.7, 95% CI 0.5-0.9) and higher paternal education (OR 0.8, 95% CI 0.6-0.9) in boys, and older age in girls (OR 0.7, 95% CI 0.5-.09), resulted protective factors against childhood overweight. No independent effects of marital status, maternal education and infant feeding patterns on childhood excess weight were identified. Perinatal and parental factors could contribute to predict the risk of being overweight/obese in children aged 6 to 12 years, which should be considered when formulating obesity prevention and intervention strategies, stressing the importance of targeting obese parents with young children.

    The European Commission has identified schools as a priority setting for health promotion, including nutrition education and intervention. The present study examined the school-day diet of Irish primary-school children with the aim of identifying opportunities for dietary improvement. Data from The National Children's Food Survey (2003-2004) were used to establish a dataset of school-days. Dietary intake data were collected from 594 children (5-12 years) using a 7-day weighed food-record. The nutritional quality of the diet was examined for the total school-day and for food eaten 'before school', 'at school' and 'after school'. Examination of dietary intake on school-days has highlighted nutritional imbalances for intakes of fat, saturated fat, added sugars, sodium and dietary fibre (DF). Mean energy (E) intake for the overall school-day was 7.1 MJ, with 16% of energy provided from food eaten 'before school', 33%E from food eaten 'at school' and 53% of energy from food eaten 'after school'. Relative to the overall school-day, food eaten 'before school' was lower in saturated fat and sodium, and higher in DF and many micronutrients. Food eaten 'at school' was relatively high in added sugars and sodium; lower in DF and micronutrients; and similar in saturated fat compared to the overall school-day. Food eaten 'after school' was relatively high in DF and vitamin A; similar in saturated fat, magnesium and sodium; and lower in added sugars and other micronutrients compared to the overall school-day. To improve the overall nutritional quality of the school-day diet, food eaten at school should be targeted. © 2014 The British Dietetic Association Ltd.

    Background Approximately 600 million children of preschool and school age are anaemic worldwide. It is estimated that half of the cases are due to iron deficiency. Consequences of iron deficiency anaemia during childhood include growth retardation, reduced school achievement, impaired motor and cognitive development, and increased morbidity and mortality. The provision of daily iron supplements is a widely used strategy for improving iron status in children but its effectiveness has been limited due to its side effects, which can include nausea, constipation or staining of the teeth. As a consequence, intermittent iron supplementation (one, two or three times a week on nonconsecutive days) has been proposed as an effective and safer alternative to daily supplementation. Objectives To assess the effects of intermittent iron supplementation, alone or in combination with other vitamins and minerals, on nutritional and developmental outcomes in children from birth to 12 years of age compared with a placebo, no intervention or daily supplementation. Search methods We searched the following databases on 24 May 2011: CENTRAL (2011, Issue 2), MEDLINE (1948 to May week 2, 2011), EMBASE (1980 to 2011 Week 20), CINAHL (1937 to current), POPLINE (all available years) and WHO International Clinical Trials Registry Platform (ICTRP). On 29 June 2011 we searched all available years in the following databases: SCIELO, LILACS, IBECS and IMBIOMED. We also contacted relevant organisations (on 3 July 2011) to identify ongoing and unpublished studies. Selection criteria Randomised and quasi-randomised trials with either individual or cluster randomisation. Participants were children under the age of 12 years at the time of intervention with no specific health problems. The intervention assessed was intermittent iron supplementation compared with a placebo, no intervention or daily supplementation. Data collection and analysis Two authors independently assessed the eligibility of studies

    To compare percutaneous nephrostomy (PCN) tube vs JJ ureteric stenting as the initial urinary drainage method in children with obstructive calcular anuria (OCA) and post-renal acute renal failure (ARF) due to bilateral ureteric calculi, to identify the selection criteria for the initial urinary drainage method that will improve urinary drainage, decrease complications and facilitate the subsequent definitive clearance of stones, as this comparison is lacking in the literature. A series of 90 children aged ≤12 years presenting with OCA and ARF due to bilateral ureteric calculi were included from March 2011 to September 2013 at Cairo University Pediatric Hospital in this randomised comparative study. Patients with grade 0-1 hydronephrosis, fever or pyonephrosis were excluded. No patient had any contraindication for either method of drainage. Stable patients (or patients stabilised by dialysis) were randomised (non-blinded, block randomisation, sealed envelope method) into PCN-tube or bilateral JJ-stent groups (45 patients for each group). Initial urinary drainage was performed under general anaesthesia and fluoroscopic guidance. We used 4.8-6 F JJ stents or 6-8 F PCN tubes. The primary outcomes were the safety and efficacy of both groups for the recovery of renal functions. Both groups were compared for operative and imaging times, complications, and the period required for a return to normal serum creatinine levels. The secondary outcomes included the number of subsequent interventions needed for clearance of stones. Additional analysis was done for factors affecting outcome within each group. All presented patients completed the study with intention-to-treat analysis. There was no significant difference between the PCN-tube and JJ-stent groups for the operative and imaging times, period for return to a normal creatinine level and failure of insertion. There were significantly more complications in the PCN-tube group. The stone size (>2 cm) was the only factor

    Full Text Available Introduction : Ureteral stones are a common problem in daily emergency department practice. Patients may be offered medical expulsive therapy (MET1 to facilitate stone expulsion and this should be offered as a treatment for patients with distal ureteral calculi, who are amenable to waiting management. Emergency department clinicians and family practitioners are often in the front line regarding the diagnosis and treatment of symptomatic nephrolithiasis and this commentary is dedicated to them because their decisions directly influence the outcome of the acute stone episode and appropriate referral patterns. Materials and Methods : The aim of this systematic review and meta-analysis was to understand the role of MET in the treatment of obstructing ureteral calculi. A bibliographic search covering the period from January 1980 to March 2010 was conducted in PubMed, MEDLINE and EMBASE. The searches were restricted to publications in English. This analysis is based on the 21 studies that fulfilled the predefined inclusion criteria. Results : A metaregression analysis of expulsion time showed a statistically significant advantage in the experimental group, in which the mean expulsion time was 6.2 days compared to 10.3 days in controls. The treatment effect on expulsion rate (P = 0.53 was partially lost as the size of the stones decreased because of the high spontaneous expulsion rate of small stones and the expulsion time was not influenced by pharmacological treatment (P = 0.76 if the stone size was smaller than 5 mm. Analysis of the tamsulosin database : A total of 1283 participants were included in the 17 studies. These studies showed that compared to standard therapy or placebo, tamsulosin had significant benefits, being associated with both a higher stone expulsion rate (P < 0.001 and reduction of the expulsion time (P = 0.02. Reductions in the need for analgesic therapy, hospitalization and surgery are also shown. Analysis of the nifedipine

    The value of flexible ureterorenoscopy (fURS) and miniaturized PNL (mPNL) for larger renal calculi is under discussion. This non-randomized prospective study aimed to evaluate fURS and mPNL for solitary renal stones of 10-30 mm size. fURS was carried out in 21 patients with last generation 7.5F endoscopes. Ureteral access sheaths were used in 19 patients. For mPNL, an 18F modified Amplatz sheath with a 14F nephroscope were used (n = 25). The procedure was performed either tubeless with an antegrade stent or a nephrostomy. Outcome and complications of both procedures were assessed. Patients' demographics and stone sizes were comparable (18 ± 5 vs. 19 ± 4 mm, P = 0.08). Patients in the fURS group had a higher mean BMI (31 vs. 27, P < 0.05). Total OR time was significantly longer for fURS (106 ± 51 vs. 59 ± 19 min., P < 0.001). More patients were stone-free after one single percutaneous treatment, while 2nd-stage treatments with fURS were common (total procedures 1.04 vs. 1.52, P < 0.001; immediate stone-free rate (SFR) 96% vs. 71.5%, P < 0.001). SFR after 4 weeks was 100% (mPNL) and 85.8% (fURS) (P < 0.01). Minor complications as classified by Clavien I or II occurred in 16 and 23.8%, mPNL and fURS, respectively, P = 0.13). No major complications (Clavien III-V) occured in both groups. Our series supports both the concept of either percutaneous or retrograde endoscopic treatment for renal calculi with both modalities offering excellent safety. However, while for fURS, a significantly higher rate of 2nd-stage procedures was necessary, and mPNL led to faster and higher SFR without increasing complication rate.

    Mechanical endovascular embolectomy using stent retrievers has gained popularity for treatment of large vessel occlusion in acute ischemic stroke. Use of open embolectomy as a direct surgical treatment has been limited, likely owing to the technical difficulty, therapeutic time window, and time-consuming procedure. We retrospectively reviewed clinical and radiographic records of patients who underwent open embolectomy for major artery occlusion at an acute stage. Clinical features, complications, and outcome of patients were analyzed. From January 2004 to September 2016, 153 patients underwent 157 open embolectomies for major artery occlusion. Complete recanalization was achieved in 96.2% of patients. A favorable outcome was observed in 43.9%. Cerebral aneurysm along the occluded artery was observed in 11 patients with 12 aneurysms. Open embolectomy resulted in a high complete recanalization rate with an acceptable safety profile. Open embolectomy is a safe and durable method of cerebral recanalization in patients with embolic stroke and can be considered as a potential treatment if endovascular embolectomy cannot be performed. The details of the occluded arteries presented here will be useful for endovascular surgeons to prevent complications. Copyright © 2017 Elsevier Inc. All rights reserved.

    Conclusion: Serum ceruloplasmin and 24-hour urinary copper examinations could be used to rule out WD in children with chronic hepatitis and hemolytic anemia. Gene analysis is helpful for prompt diagnosis of asymptomatic siblings and patients with atypical features. Zinc treatment is generally safe in pediatric patients with WD. However, its adverse effects should be monitored.

    Wilson's disease (WD) is an autosomal recessive defect of cellular copper export. Early diagnosis in children is difficult due to its obscure clinical presentations. The efficacy of zinc salts is well documented, although there are limited data concerning zinc use in pediatric patients with WD. We performed a retrospective analysis of clinical features, laboratory results and treatment responses in children with WD diagnosed at Taichung Veterans General Hospital between 1996 and 2008. Diagnosis was established by low serum ceruloplasmin, high 24-hour urinary copper excretion, presence of Kayser-Fleischer rings, and mutation analysis. Eleven children were included in this study. The main initial presentations were impaired liver function tests (6/11) and hemolytic anemia (2/11). Gene studies in seven children showed six different mutations (G934D, R778Q, C490X, 304insC, IVS4-1 G > C, P992I) and one possible novel mutation (L1181P). All patients had improved liver function tests and hemoglobin levels after treatment with D-penicillamine, trientine and zinc supplement therapy. During a mean period of 3.4 +/- 2.1 years with zinc therapy, six patients had serum zinc levels above the normal limit, and seven patients had serum copper levels below the normal range. Serum ceruloplasmin and 24-hour urinary copper examinations could be used to rule out WD in children with chronic hepatitis and hemolytic anemia. Gene analysis is helpful for prompt diagnosis of asymptomatic siblings and patients with atypical features. Zinc treatment is generally safe in pediatric patients with WD. However, its adverse effects should be monitored. Copyright 2010 Taiwan Pediatric Association. Published by Elsevier B.V. All rights reserved.

    Penetrating spinal cord injuries (SCIs) are an uncommon injury and not reported very frequently. SCIs cause sensory, motor and genitourinary system problems or a combination of sensorimotor dysfunctions. These are among the most debilitating kinds of disorders and negatively affect quality of life, not only for the patient, but also for their family members. Therefore, the present study aims to evaluate complete or incomplete SCIs and the course of the injury and the prognosis for SCIs caused by stab wounds. This case-series design study was performed on 57 patients attending the emergency department of Taleqani Trauma Center (Kermanshah, Iran) due to SCIs caused by violent encounters involving sharp objects such as a knife, dagger, whittle and Bowie-knife between 1999 and 2011. An assessment of sensory and motor functions was performed as part of the neurological examination on admission, and during the treatment, using the Frankel Classification grading system, and the results were recorded. The average age of patients was 27 years (SD= 7.9, Range=17 to 46 years). The results of the study showed a proportion of cervical, thoracic and lumbar injuries of 23 (40%), 24 (42%) and 10 (18%), respectively. There was no case of cerebrospinal fluid leakage (CSF) or infection at the wound site in the subjects. Regarding the extent of the SCI, the combined neurological assessment showed that several patients (43%) had a complete SCI with no sensory and motor functions in the sacral segments and the segments below the site of injury. In 32 patients (57%) incomplete injuries were observed; i.e. they showed only some degrees of sensory-motor functions that were below the neurological level. Both complete and incomplete SCIs are of great importance because the prognosis of SCI is directly associated with the location and extent of injury. It should be considered that partial recovery from SCIs is possible in few cases of complete injuries. Therefore, all the patients should be treated carefully and seriously.

    There are no comprehensive surveys relating the reported high prevalence of asthma and allergic diseases in athletes to comorbidities and immune changes associated with intense chronic exercise. This 12-year survey aims to evaluate several clinical, functional and immunological parameters in order to assess features, trend and burden of asthma, allergy, infections and autoimmune diseases, in a large homogeneous population of Olympic athletes. Six hundred and fifty-nine Italian Olympic athletes were studied through four cross-sectional surveys performed between 2000 and 2012 before the Summer and Winter Olympics. Clinical diagnosis of allergic, autoimmune and infectious diseases was complemented by: skin-prick tests (n = 569); pulmonary function tests (n = 415); total (n = 158) and specific (n = 72) serum IgE; serum autoantibodies (n = 30), cytokines and growth factors (n = 92); flow cytometry (n = 135). The prevalence of asthma and/or exercise-induced bronchoconstriction was 14.7%, with a significant increase (P = 0.04) from 2000 (11.3%) to 2008 (17.2%). The prevalence of rhinitis, conjunctivitis, skin allergic diseases and anaphylaxis was 26.2%, 20.0%, 14.8% and 1.1%, respectively. Sensitization to inhalant allergens was documented in 49.0% of athletes, being 32.7% in 2000 and 56.5% in 2008 (P < 0.0001). Food, drug and venom allergy was present in 7.1%, 5.0% and 2.1% of athletes, respectively. The high prevalence of asthma and allergy was associated with recurrent upper respiratory tract (10.3%) and herpes (18.2%) infections, an abnormal T cell subset profile and a general down-regulation of serum cytokines with a significantly lower IFN-γ/IL-4 ratio. A chronic and intense physical exercise may cause a transient immunodepression with a preferential shift to a Th2 response, associated with abnormalities of the respiratory tract.

    Full Text Available Overweight and obesity are increasing health problems that are not restricted to adults only. Childhood obesity is associated with metabolic, psychological and musculoskeletal comorbidities. However, knowledge about the effect of obesity on the foot function across maturation is lacking. Decreased foot function with disproportional loading characteristics is expected for obese children. The aim of this study was to examine foot loading characteristics during gait of normal-weight, overweight and obese children aged 1-12 years.A total of 10382 children aged one to twelve years were enrolled in the study. Finally, 7575 children (m/f: n = 3630/3945; 7.0±2.9 yr; 1.23±0.19 m; 26.6±10.6 kg; BMI: 17.1±2.4 kg/m2 were included for (complete case data analysis.

    As part of a risk-management approach, sound epidemiological data are needed to develop prevention programs. A recent review on soccer injuries of players younger than 19 years concluded that prospective data concerning children are lacking. To analyze the incidence and characteristics of soccer injuries in children aged 7 to 12 years. Descriptive epidemiological study. The present survey was a prospective descriptive epidemiological study on soccer injuries over 2 seasons in the Czech Republic and Switzerland. Exposure of players during training and match play (in hours) and injury data were reported by coaches via an Internet-based registration system. Location, type, and severity of injuries were classified according to an established consensus. Injury characteristics are presented as absolute numbers and injury incidence rates (injuries per 1000 hours of soccer exposure). An injury was defined as any physical complaint sustained during a scheduled training session or match play resulting in at least 1 of the following: (1) inability to complete the current match or training session, (2) absence from subsequent training sessions or matches, and (3) injury requiring medical attention. In total, 6038 player-seasons with 395,295 hours of soccer exposure were recorded. The mean (±SD) age of the players was 9.5 ± 2.0 years, and 3.9% of the participants were girls. A total of 417 injuries were reported. Most (76.3%) injuries were located in the lower limbs, with 15.6% located in the upper limbs. Joint and ligament injuries comprised 30.5%, contusions 22.5%, muscle and tendon injuries 18.5%, and fractures and bone injuries 15.4% of all injuries; 23.7% of injuries led to more than 28 days of absence from sport participation. The overall injury incidence was 0.61 (95% CI, 0.53-0.69) injuries per 1000 hours of soccer exposure during training sessions and 4.57 (95% CI, 4.00-5.23) during match play. Injury incidence rates increased with increasing age. The observed injury

    Full Text Available Introduction: The World Health Organization has a long tradition on the methodology and monitorization of oral health epidemiological investigations, even in the field of dental caries. According to the targets to be attained in 2020, at the age of 6 years, 80% of children should be cavity‐free and, at the age of 12, DMFT should be no more than 1.5. Based on WHO targets for 2020, an epidemio‐ logical study was performed on school children affected by dental caries, aged between 7‐12 years, from the rural areas of the Dolj County. Methodology: The study protocol included conventional and meticulous visual clinical examination of students, according to WHO methodology, in the Pedodontic Clinics of Craiova ‐ Faculty of Medical Dentistry. Also calculated was the DMFT index, by analy‐ sis of the DT, MT, FT components, as well as the dmft index, by analysis of the dt, mt, ft components. Results: The mean indices of carious experience in temporary den‐ tition decrease with age, due to the progressive disappear‐ ance of milk teeth. The DMFT index values are given, in particular, by components that indicate the number of teeth affected by caries and not of the blocked ones. Con‐ clusions: The results obtained emphasize the need for den‐ tal health education programs at national and community level, the kindergartens and schools having a great poten‐ tial to influence dental health care habits in children. Also emphasized was the need for regional prevention pro‐ grams, as part of an overall national program, which has to consider the socio‐economic and cultural factors.

    Research on relationships between personality and cognitive abilities has so far resulted in inconsistent findings regarding the strength of the associations. Moreover, relationships have rarely been compared longitudinally and bidirectionally between midlife versus late-life cohorts by considering different personality traits as well as multiple cognitive domains over a long-term follow-up period. We hypothesize that the interplay between the "Big Five" personality traits (Neuroticism, Extraversion, Openness to Experience, Agreeableness and Conscientiousness) and cognitive abilities (information processing speed, crystallized intelligence, fluid intelligence) may change from midlife to old age due to age-associated changes in cognitive and personality plasticity. We used data from the German Interdisciplinary Longitudinal Study of Adult Development (ILSE study; n = 1,002). Participants were either born in 1950/52 (midlife sample, n = 502) or in 1930/32 (late-life sample, n = 500) and followed up for up to 12 years. Based on bivariate latent change score regression models (adjusted for gender, education, self-rated and physician-rated health), we observed that, apart from very few exceptions, the intervariable cross-lagged associations between personality traits and cognitive abilities were generally similar between cohorts. Moreover, in case of neuroticism, extraversion, and openness, the effects of cognitive abilities on change in personality were stronger than the reversed effects. Our findings thus suggest that the so far predominant perspective of personality in middle adulthood and late-life as a predictor, rather than as an outcome, of cognitive abilities needs more differentiation and reconsideration.

    To study the impact of preprocedure intravenous urography (IVU) on the outcome of SWL for renal stones. Two hundred patients with radiopaque renal stones IVU before the start of SWL, whereas patients in the second group (n = 100) underwent SWL without IVU. Thirteen patients in the IVU group and seven patients in the no-IVU group were excluded from the study. Patients in both groups received the same treatment and follow-up protocols. Intraoperative and postoperative complications were evaluated in all patients. An endpoint assessment by plain film was done 3 months after the conclusion of treatment to evaluate the success and stone-free rates. The success rate (81.6% in group 1 v 77.4% in group 2), stone-free rate (65.5% v 62.3%), re-treatment rate (59.8% v 69.9%), auxiliary-procedure rate (6.9% v 5.4%), and complication rate (11.5% v 14%) were similar in the two groups. It is not necessary to obtain an IVU for patients who have renal calculi with no or minimal back pressure before scheduling them for SWL, thus minimizing the cost, avoiding exposure to contrast medium, and reducing radiation exposure.

    Thirty patients with partial or total staghorn lithiasis or calculi larger than 30 mm were treated by piezoelectric lithotripsy (PEL) monotherapy using an EDAP LT-01 lithotripter with ultrasound guidance. Nineteen of these patients had a pelvic stone; the other 11 had partial (nine) or total (two) staghorn lithiasis. All patients first underwent an initial lithotripsy session. No anesthesia or intravenous sedation was required in any case. If stone fracturization was achieved after this first session, a double J stent was inserted before the second lithotripsy session. Prior to the first session, 18 of 30 patients had a sterile urine culture; 12 of 30 presented major distention of the excretory tract. Results were analyzed to determine those factors influencing the outcome of this therapy. Three months after the first session, patients were considered cured if their stone had completely disappeared on abdominal plain films (14/30 = 46%). In seven patients (23.3%), fracturization had occurred but residual fragments remained (1-3 fragments less than or equal to 4 mm). No fracturization was obtained after the first session in nine patients (30.7%) (one total staghorn lithiasis, eight pelvic stones). The mean number of treatment sessions was five (range 1-15). Complications occurred in only 10% of patients (3/30): two steinstrasse and one acute pyelonephritis. Eighty-three percent of patients without major excretory tract distention and 55% of patients whose initial urine culture was sterile, achieved a stone-free state.(ABSTRACT TRUNCATED AT 250 WORDS)

  18. Scintigraphy and Doppler ultrasonography for the evaluation of obstructive urinary calculi

    2001-06-01

    Full Text Available Forty-seven patients with unilateral obstructive calculi (12 males and 35 females were submitted to 99mTc-diethylene triamine pentaacetic acid (DTPA or 99mTc-dimercaptosuccinic acid (DMSA scans for assessment of renal function. The scans revealed unilateral functional deficit in 68 and 66% of the patients, respectively. A calculus size of 1.1 to 2.0 cm was significantly associated with deficit detected by DTPA, but duration of obstruction and calculus localization were not. After relief of the obstruction, the mean percent renal function of the affected kidney was found to be significantly increased from 25 ± 12% to 29 ± 12% in DTPA and from 21 ± 15% to 24 ± 12% in DMSA. Initial Doppler ultrasonography performed in 35 patients detected an increased resistive index in 10 (29%. In the remaining patients with a normal resistive index, ureteral urinary jet was observed, indicating partial obstruction. The high frequency of renal function impairment detected by DTPA and of tubulointerstitial damage detected by DMSA as well as the slight amelioration of unilateral renal function after relief of obstruction suggest that scintigraphy assessment may help evaluate the unilateral percentage of renal function and monitor renal function recovery when it occurs. The presence of a urinary jet detected by Doppler ultrasonography further indicates the severity of obstruction and the recovery prognosis.

    This study examines 1,791 consecutive laparoscopic adjustable gastric banding (LAGB) procedures with up to 12 years follow-up. Long-term results of LAGB with a high follow-up rate are not common. Between September 1993 and December 2005, 1,791 consecutive patients (75.1% women, mean age 38.7 years, mean weight 127.7 +/- 24 kg, mean BMI 46.2 +/- 7.7) underwent LAGB by the same surgical team. Perigastric dissection was used in 77.8% of the patients, while subsequently pars flaccida was used in 21.5% and a mixed approach in 0.8%. Data were analyzed according to co-morbidities, conversion, short- and long-term complications and weight loss. Fluoroscopy-guided band adjustments were performed and patients received intensive follow-up. The effects of LAGB on life expectancy were measured in a case/control study involving 821 surgically-treated patients versus 821 treated by medical therapy. Most common baseline co-morbidities (%) were hypertension (35.6), osteoarthritis (57.8), diabetes (22), dyslipidemia (27.1), sleep apnea syndrome (31.4), depression (21.2), sweet eating (22.5) and binge eating (18.5). Conversion to open was 1.7%: due to technical difficulties (1.2) and due to intraoperative complications (0.5). Together with the re-positioning of the band, additional surgery was performed in 11.9% of the patients: hiatal hernia repair (2.4), cholecystectomy (7.8) and other procedures (1.7). There was no mortality. Reoperation was required in 106 patients (5.9%): band removal 55 (3.7%), band repositioning 50 (2.7 %), and other 1 (0.05 %). Port-related complications occurred in 200 patients (11.2%). 41 patients (2.3%) underwent further surgery due to unsatisfactory results: removal of the band in 12 (0.7%), biliopancreatic diversion in 5 (0.27%) and a biliopancreatic diversion with gastric preservation ("bandinaro") in 24 (1.3%). Weight in kg was 103.7 +/- 21.6, 102.5 +/- 22.5, 105.0 +/- 23.6, 106.8 +/- 24.3, 103.3 +/- 26.2 and 101.4 +/- 27.1 at 1, 3, 5, 7, 9, 11 years

    To evaluate the clinical application value of X-ray digital DTSynthesis (DTS) based on IVU (Intravenous Urography)in urinary calculi contrasted with unenhanced multidetector-row computerized tomography. 75 patients suspected of urinary calculi underwent IVU, DTS based on IVU and UMDCT. The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive of the three imaging ways were acquired according to operations, respectively. Chi-square test was used to evaluate the difference among the three ways. In 75 cases, 60 cases were proved to be urinary calculi. The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive of IVU, DTS based on IVU,UMDCT is 70.0%, 73.3%, 70.7%, 91.3%, 37.9%; 91.7%, 86.7%, 90.7%, 96.5%, 72.2%; 96.7%, 86.7%, 94.7%, 96.7%, 86.7%, respectively.No significant differences between DTS based on IVU and UMDCT were found in sensitivity, specificity, accuracy, positive predictive value and negative predictive. Both cases are better than IVU in diagnostic ability. There is no significant difference in diagnostic ability of urinary calculi between DTS and UMDCT. DTS can be used as a routine imaging technique in diagnosis and follow up of urinary calculi.

It was selected 210 children, which were interviewed in the preoperative holding area of a general hospital. Anxiety was evaluated using the modified Yale Preoperative Anxiety Scale (mYPAS). Sociodemographic and clinical variables were analyzed as exposure and anxiety (mYPAS final score>30) as outcome. Logistic regression was used to identify factors associated with preoperative anxiety. forty-two percent (42.0%) of children presented preoperative anxiety (CI95%: 35.7%-48.6%), with mean scores equal to 30.1 (SD=8.4). Factors associated with preoperative anxiety were: age group of 5-6 years (OR=2.28; p=0.007) and socioeconomic status classified as class C (OR=2.39; p=0.016). the evaluation of children who wait for outpatient surgery should be multidimensional and comprise information on age and socioeconomic status, in order to help in the identification and early treatment of preoperative anxiety. estimar a prevalência e os fatores associados à ansiedade pré-operatória em crianças que aguardam cirurgia ambulatorial. análise transversal de dados da linha de base de um estudo de coorte prospectiva que investiga os preditores de dor pós-operatória em crianças de 5 a 12 anos, submetidas à herniorrafia inguinal e umbilical.

    Full Text Available A number of trials have been undertaken to assess whether the intake of omega-3 long-chain polyunsaturated fatty acids (n-3 LCPUFA during pregnancy can influence the neurological development of the offspring, yet no consensus from these trials has been reached. We aimed to investigate the long-term effects (12 years of fish oil supplementation in pregnancy on neurodevelopment, including cognition, language and fine motor skills. In a follow up of a previously published randomised controlled trial of 98 pregnant women, their children were assessed at 12 years of age using a battery of neurodevelopmental assessments. Fifty participants were assessed at 12 years, with 25 participant’s mothers receiving fish oil supplementation, and 25 receiving control capsules. There were no significant differences for any of the assessment measures completed. Our data indicate that fish oil supplementation during pregnancy does not influence the cognition, language or fine motor skills of children in late primary school (12 years of age.

    To assess self-perceived oral health-related quality of life (OHRQoL) in 12-year-olds living in two areas in the Barents region: North-West Russia (Arkhangelsk) and Northern Norway (Tromsø). Sampling was performed according to a stratified cluster design and consisted of 590 Russian and 264 Norwegian 12-year-olds and their parents. After written consent from their parents, 514 Russian (87% attendance) and 124 Norwegian (47% attendance) children entered the study. The study included clinical examination (children) and questionnaires (children and parents). Dental caries and the aesthetic dental appearance were recorded under field conditions. Self-reports on background variables and oral health-related quality of life questions (CPQ11-14) were completed in classroom settings by children and at home by parents. OHRQoL was found to vary depending on country of origin, with higher scores of CPQ11-14 domains among 12-year-olds from Russia. OHRQoL was found to be associated with dental caries, with higher scores among 12-year olds with caries. Inferior emotional and social well-being were established as having the strongest association with quality of life. Dental caries showed an independent effect on OHRQoL scores, but this effect disappeared when controlling for background variables, with country of origin, family economy, parental education and aesthetic appearance as the most influential (R²=0.14). Norwegian 12-year-olds had better oral health and OHRQoL than their Russian counterparts. The impact of dental caries on OHRQoL was weak and aesthetic dental appearance and socio-economic determinants were found to be more important, probably reflecting the great differences in the standards of living between Northern Norway and North-West Russia.

    Full Text Available Purpose: To determine the efficacy of phosphodiesterase type 5 inhibitors (PDE5i as medical expulsive therapy (MET for the treatment of distal ureteral calculi. Materials and Methods: A search strategy was conducted in the MEDLINE, CENTRAL, and Embase databases. Searches were also conducted in other databases and unpublished literature. Clinical trials were included without language restrictions. The risk of bias was evaluated with the Cochrane Collaboration’s tool. An analysis of random effects due to statistical heterogeneity was conducted. The primary outcome was the expulsion rate of the distal ureteral calculus in 28 days. The secondary outcomes were the time to expulsion, side effects of treatment, and amount (mg of nonopioid analgesia. The measure of the effect was the risk difference (RD with a 95% confidence interval (CI. The planned interventions were PDE5i vs. placebo, tadalafil vs. placebo, and tadalafil vs. tamsulosin. Results: Four articles were included in the qualitative and quantitative analysis. Records of 580 patients were found among the four studies. A low risk of bias was shown for the majority of the study items. The calculi expulsion rate had an RD of 0.26 (95% CI, 0.15–0.37 and a less prolonged expulsion as a secondary outcome with a mean difference of -4.39 days (95% CI, -6.69 to -2.09 in favor of PDE5i compared with the placebo. No significant difference was found for these outcomes when comparing tadalafil with tamsulosin. Conclusions: Compared with a placebo, PDE5i could be effective as MET for the treatment of distal ureter calculi.

    This prospective case study illustrates the ideas on the developmental origins of some cases of autism that were described in Part 1 of this article. We explored and found support for several systemic hypotheses regarding the experience of 'Graeme' and his mother. Graeme's story is told prospectively from the age of 3 until 15. Three independent sources of information are reported: hypotheses from the literature and case review in Part 1 of this article, the school's experience, and observations from the assessments of attachment when Graeme was turning 6. These three streams of information are integrated here. The review of the literature and clinical cases gives us a wide-angle lens, empirically supporting our focus on danger in relationships. The school's experience describes working with a child with undiagnosed autism. The assessments of attachment both provide information about family members' psychological strategies for protection from danger and also include the mother's childhood history of family threat. Their synthesis permits us to construct a developmental history, from Graeme's mother's childhood history of being triangulated into her parents' hidden marital discord to it's repetition for Graeme in her own marriage. New observations included mum's postural/gestural communication to Graeme and her possible ambivalence about males. Strikingly, Graeme was a case study (Attachment & Family Therapy, ch. 6) before he was diagnosed with autism. That presentation focused on Graeme's feeling of rejection by his father. In the same book, an interpersonal formulation of autism was offered (ch. 3), but it was not connected to Graeme, showing that when one lacks crucial information, the clinical formulation is distorted. The crucial information in this case was the mother's psychological history. Our case suggests that filling the blind spot in the research on autism with information about family functioning over at least two generations might change the

    Full Text Available Purpose To investigate the anti-urolithiatic effect of cow urine ark (medicinal distilled cow urine on ethylene glycol (EG induced renal calculi. Materials and Methods 36 male Wistar rats were randomly divided into 6 equal groups. Group I animals served as vehicle control and received distilled water for 28 days. Group II to VI animals received 1% v/v EG in distilled water for 28 days. Group II served as EG control. Group III and IV (preventive groups received cow urine ark orally for 28 days in doses of 1 mL/kg and 2 mL/kg, respectively. Group V and VI (treatment groups received 1 mL/kg and 2 mL/kg cow urine ark orally, respectively from 15th to 28th days. 24-hour urine samples were collected on day 0 and 28. Urine volume and oxalate levels were measured. On day 28, blood was collected for biochemical parameters. Animals were sacrificed and kidneys were harvested, weighed and histopathologically evaluated for calcium oxalate (CaOx crystals. To calculate the percentage of inhibition of mineralization, simultaneous flow static in-vitro model was used. Results EG significantly increased urine oxalate, serum creatinine, blood urea level; kidney weight and CaOx deposits. Provision of cow urine ark resulted in significantly lower levels of urine oxalate, serum creatinine, blood urea and CaOx depositions as compared to Group II. (p value < 0.05 It also significantly restored kidney weight. (p value < 0.05 Cow urine ark inhibited 40% and 35% crystallization of CaOx and calcium phosphate, respectively. Conclusion Cow urine ark is effective in prevention and treatment of EG induced urolithiasis in Wistar rats.

    Renal calculi formation is one of the most common urological disorders. Urinary stone disease is a common disease, which affects 10‑12% of the population in industrialized countries. In males, the highest prevalence of the disease occurs between the age of 20 and 40 years, while in females, the highest incidence of the disease occurs later. Previous studies have shown that long‑term exposure to oxalate is toxic to renal epithelial cells and results in oxidative stress. In the present study, a methanolic extract of aerial parts of Urtica dioica was screened for antiurolithiatic activity against ethylene glycol and ammonium chloride‑induced calcium oxalate renal stones in male rats. In the control rats, ethylene glycol and ammonium chloride administration was observed to cause an increase in urinary calcium, oxalate and creatinine levels, as well as an increase in renal calcium and oxalate deposition. Histopathological observations revealed calcium oxalate microcrystal deposits in the kidney sections of the rats treated with ethylene glycol and ammonium chloride, indicating the induction of lithiasis. In the test rats, treatment with the methanolic extract of Urtica dioica was found to decrease the elevated levels of urinary calcium, oxalate and creatinine, and significantly decrease the renal deposition of calcium and oxalate. Furthermore, renal histological observations revealed a significant reduction in calcium oxalate crystal deposition in the test rats. Phytochemical analysis of the Urtica dioica extract was also performed using liquid chromatography‑electrospray ionization tandem mass spectrometry and high-performance liquid chromatography with photodiode array detection, to determine the chemical composition of the extract. The eight chemical constituents identified in the extract were protocatechuic acid, salicylic acid, luteolin, gossypetin, rutin, kaempferol‑3‑O‑rutinoside, kaempferol‑3‑O‑glucoside and chlorogenic acid.

    The management of upper urinary tract stones in patients with spina bifida is challenging but poorly described in the literature. We compared urolithiasis interventions and related complications in patients with spina bifida to those in other stone formers using a national database. We retrospectively reviewed the NIS to identify hospital admissions for renal and ureteral stones from 1998 to 2011. We used ICD-9-CM codes to identify urological interventions, including shock wave lithotripsy, ureteroscopy, percutaneous nephrolithotomy and ureteral stent placement. NSQIP data were used to identify postoperative complications. We identified 4,287,529 weighted stone hospital admissions, including 12,315 (0.3%) of patients with spina bifida. Compared to those without spina bifida the patients with spina bifida who had urolithiasis were significantly younger (mean age 34 vs 53 years), more likely to have public insurance (72% vs 44%) and renal vs ureteral calculi (81% vs 58%), and undergo percutaneous nephrolithotomy (27% vs 8%). After adjusting for age, insurance, comorbidity, treatment year, surgery type, stone location and hospital factors patients with spina bifida were more likely to have urinary tract infections (OR 2.5), urinary complications (OR 3.1), acute renal failure (OR 1.9), respiratory complications (OR 2.0), pneumonia (OR 1.5), respiratory insufficiency (OR 3.2), prolonged mechanical ventilation (OR 3.2), sepsis (OR 2.7), pulmonary embolism (OR 3.0), cardiac complications (OR 2.4) and bleeding (OR 1.6). Compared to those without spina bifida the patients with spina bifida who were hospitalized for urolithiasis were younger, and more likely to have renal stones and undergo percutaneous nephrolithotomy. Urolithiasis procedures in patients with spina bifida were associated with a significantly higher risk of in-hospital postoperative complications.

    Full Text Available Abstract Background The aim of this study was to comprehensively examine clinical risk factors, including suicide intent and hopelessness, for suicide and risk of death from all causes after attempted suicide over a 12-year follow-up period. Methods A systematic sample of 224 patients from consecutive cases of attempted suicide referred to health care in four Finnish cities between 1 January and 31 July 1990 was interviewed. Results After 12 years of follow-up 22% of these patients had died, 8% by committing suicide. The only statistically significant risk factor for eventual suicide was high scores on Beck's Suicidal Intention Scale. Male gender, older age, physical illness or disability and high scores on Beck's Suicidal Intention Scale predicted death overall. Conclusions Following attempted suicide, high intention to kill oneself is a significant risk factor for both death from all causes and suicide.

    A number of children are unable to comply with an MRI procedure and require general anesthetic. However, we lack information about which factors are associated with MRI compliance in young children. To determine the strongest predictors of MRI compliance, focusing on variables that can be easily rated by patients' parents. A sample of 205 children ages 3-11 years (mean age 6.6 years) who were at risk of non-compliance were recruited from a children's hospital. Their parents completed a behavior assessment scale for children as well as a questionnaire that assessed their expectations of compliance and perception of their child's typical medical compliance. The children subsequently completed a mock MRI with an educational play therapist and a clinical MRI, with the quality of the scan scored by the MRI technologist. Overall, 88.3% of children complied with the clinical scan and achieved diagnostic images, with age unrelated to compliance in this well-prepared patient group. The strongest predictors of MRI compliance were parental expectations and ratings of how well the child typically copes with medical procedures. Non-compliance was related to child attention problems and to poor adaptability among children. A total of 64 preschool-age children (91.4%) and 110 school-age children (95.7%) were correctly classified as compliant or non-compliant based on these predictor variables. A child's temperament, medical experiences and parental expectations provide important information in predicting which children successfully comply with an MRI procedure and which require general anesthesia. Further study is needed to explore the utility of these variables in predicting compliance at sites that do not have access to an MRI simulator. (orig.)

    To establish a reference interval of alkaline phosphatase for healthy children of various ethnicities, aged 0 years to 12 years in China. According to the Clinical and Laboratory Standards Institute guideline C28-A3, blood specimens were collected in the morning after overnight fasting from 502 healthy children to determine the alkaline phosphatase (ALP) level, using the Beckman AU5800 automatic biochemical analyzer. Children were grouped by sex and age. The age groups were as follows: 0 to 1 year, 1 to 3 years, 3 to 6 years, and 6 to 12 years. There were no significant differences between the sex and age groups for the age groups of 0 to 1 year, 1 to 3 years, and 3 to 6 years; as a result, we combined those groups into a single group. The reference interval of ALP is 81.9 to 350.3 U per L in the group aged 0 to 6 years and 48.8 to 445.9 U per L in the group aged 6 to 12 years. The results of this study establish a reference interval for ALP in healthy children, which will provide a basis for screening, diagnosing, and monitoring bone or liver-related diseases in children.

    2010-06-01

    Full Text Available Abstract Background Transgenic trees currently are being produced by Agrobacterium-mediated transformation and biolistics. The future use of transformed trees on a commercial basis depends upon thorough evaluation of the potential environmental and public health risk of the modified plants, transgene stability over a prolonged period of time and the effect of the gene on tree and fruit characteristics. We studied the stability of expression and the effect on resistance to the fire blight disease of the lytic protein gene, attacin E, in the apple cultivar 'Galaxy' grown in the field for 12 years. Results Using Southern and western blot analysis, we compared transgene copy number and observed stability of expression of this gene in the leaves and fruit in several transformed lines during a 12 year period. No silenced transgenic plant was detected. Also the expression of this gene resulted in an increase in resistance to fire blight throughout 12 years of orchard trial and did not affect fruit shape, size, acidity, firmness, weight or sugar level, tree morphology, leaf shape or flower morphology or color compared to the control. Conclusion Overall, these results suggest that transgene expression in perennial species, such as fruit trees, remains stable in time and space, over extended periods and in different organs. This report shows that it is possible to improve a desirable trait in apple, such as the resistance to a pathogen, through genetic engineering, without adverse alteration of fruit characteristics and tree shape.

    It has been reported that borderline personality related characteristics can be observed in children, and that these characteristics are associated with increased risk for the development of borderline personality disorder. It is not clear whether borderline personality related characteristics in children share etiological features with adult borderline personality disorder. We investigated the etiology of borderline personality related characteristics in a longitudinal cohort study of 1,116 pairs of same-sex twins followed from birth through age 12 years. Borderline personality related characteristics measured at age 12 years were highly heritable, were more common in children who had exhibited poor cognitive function, impulsivity, and more behavioral and emotional problems at age 5 years, and co-occurred with symptoms of conduct disorder, depression, anxiety, and psychosis. Exposure to harsh treatment in the family environment through age 10 years predicted borderline personality related characteristics at age 12 years. This association showed evidence of environmental mediation and was stronger among children with a family history of psychiatric illness, consistent with diathesis–stress models of borderline etiology. Results indicate that borderline personality related characteristics in children share etiological features with borderline personality disorder in adults and suggest that inherited and environmental risk factors make independent and interactive contributions to borderline etiology.

    To retrospectively determine which features of urinary calculi are associated with their detection after virtual elimination of contrast medium at dual-energy computed tomographic (CT) urography by using a novel tin filter. The institutional ethics committee approved this retrospective study, with waiver of informed consent. A total of 152 patients were examined with single-energy nonenhanced CT and dual-energy CT urography in the excretory phase (either 140 and 80 kV [n=44] or 140 and 100 kV [n=108], with tin filtration at 140 kV). The contrast medium in the renal pelvis and ureters was virtually removed from excretory phase images by using postprocessing software, resulting in virtual nonenhanced (VNE) images. The sensitivity regarding the detection of calculi on VNE images compared with true nonenhanced (TNE) images was determined, and interrater agreement was evaluated by using the Cohen k test. By using logistic regression, the influences of image noise, attenuation, and stone size, as well as attenuation of the contrast medium, on the stone detection rate were assessed. Threshold values with maximal sensitivity and specificity were calculated by means of receiver operating characteristic analyses. Eighty-seven stones were detected on TNE images; 46 calculi were identified on VNE images (sensitivity, 52.9%). Interrater agreement revealed a κ value of 0.95 with TNE images and 0.91 with VNE data. Size (long-axis diameter, P=.005; short-axis diameter, P=.041) and attenuation (P=.0005) of the calculi and image noise (P=.0031) were significantly associated with the detection rate on VNE images. As threshold values, size larger than 2.9 mm, maximum attenuation of the calculi greater than 387 HU, and image noise less than 20 HU were found. After virtual elimination of contrast medium, large (>2.9 mm) and high-attenuation (>387 HU) calculi can be detected with good reliability; smaller and lower attenuation calculi might be erased from images, especially with

    ABSTRACT Background: A malocclusion is an irregularity of the teeth or a malrelationship of the dental arches beyond the range of what is accepted as normal. Objectives: To determine the prevalence of malocclusion in children aged 10-12 years in Kozhikode district of Kerala, South India. Materials and methods: A descriptive cross-sectional study was conducted among schoolchildren aged 10-12 years in six schools in Kozhikode district of Kerala, South India. A total of 2,366 children satisfied the inclusion criteria. Occlusal characteristics like crossbite, open bite, deep bite, protrusion of teeth, midline deviations, midline diastema and tooth rotation were recorded. The data were tabulated and analyzed using Chi-square test. Results: The results revealed that the overall prevalence of malocclusion was 83.3%. Of this, 69.8% of the children had Angle’s class I malocclusion, 9.3% had class II malocclusion (division 1 = 8.85%, division 2 = 0.5%) and 4.1% had class III malocclusion; 23.2% showed an increased overjet (>3 mm), 0.4% reverse overjet, 35.6% increased overbite (>3 mm), 0.29% open bite, 7.2% crossbite with 4.6% crossbite of complete anterior teeth, 63.3% deviation of midline, 0.76% midline diastema and 3.25% rotated tooth. No significant differences in gender distributions of malocclusions were noted except for increased overjet and overbite. Conclusion: There is high prevalence of malocclusion among schoolchildren in Kozhikode district of Kerala. Early interception and early correction of these malocclusions will eliminate the potential irregularities and malpositions in the developing dentofacial complex.

    We report updated results at a median follow-up of 12 years of a phase II trial assessing first-line MATILDE chemotherapy and response-tailored radiotherapy in patients with primary CNS lymphomas (PCNSL). Forty-one HIV-negative patients (18-70 years; Eastern Cooperative Oncology Group performance status ≤3) with histologically confirmed PCNSL received 3 courses of MATILDE chemotherapy followed by whole-brain radiotherapy (WBRT). Chemotherapy activity was the primary endpoint. Overall response rate was 76% (95% confidence interval [CI] 63%-89%) after chemotherapy and 83% (95% CI 71%-95%) after chemotherapy ± radiotherapy. At a median follow-up of 144 months (range 47-153), 31 patients experienced an event: relapse in 24, progressive disease in 3, and toxic death in 4, with a 5-year progression-free survival of 24% ± 8%. Two patients experienced a late relapse (100 and 101 months). Nine patients are alive and disease-free, 8 of whom are alive at >10 years, with a 5-year overall survival of 30% ± 7%. At 10 years from diagnosis, no patient showed chronic hematologic and nonhematologic toxicities, with a Mini-Mental State Examination score of ≥29 in all cases but one. At a median follow-up of 12 years, MATILDE regimen followed by WBRT confirmed the previously reported survival plateau, which further proves its long-lasting efficacy with acceptable neurologic deficits. This study provides Class IV evidence that in patients with PCNSL, MATILDE chemotherapy followed by response-tailored radiotherapy increases the probability of disease remission at 12 years.

    To evaluate the effect of exposure to positive images of dentistry on dental anxiety among 7 to 12 years old children. Controlled trial. Assessment of anxiety and analysis of data were conducted blind to experimental condition. Assessment of anxiety was carried out in the waiting room prior intervention, postintervention into the operatory during the treatment and again after the completion of treatment. Anticipatory anxiety was recorded by Venham's picture test (VPT). Sixty children of 7 to 12 years age group. PARTICIPANTS were randomly assigned to one of two conditions. In both conditions the participant was asked to look at photographs for 2 minutes in the waiting area prior to their appointment. The intervention consisted of viewing positive images of dentistry and dental treatment (study group), the (control group) consisted of neutral images. The assessment of anticipatory dental anxiety was made blind to experimental condition and statistical analysis was conducted blind to group membership. Anticipatory anxiety assessed by the VP T. A total of 60 subjects participated in the study and were equally and randomly allotted to study group (positive image) and control group (neutral image). The mean anxiety score found at waiting area before intervention, after intervention (OPD) and postoperative was statistically significant in study group.

    Full Text Available Incidence rate of symphysis mandible fracture in children was about 15 – 20%. Boys are effected twice as frequently as girls. The pattern of craniomaxillofacial fractures seen in children varies with evolving skeletal anatomy and socioenvironmental factors. The treatment of pediatric maxillofacial fractures is due to physiological, developmental, and anatomical characteristic of children. Management of pediatric mandible fracture by anatomic reduction is combine with stabilization adequate to maintain it until bone union has occured. This case report is aimed to explain about the management of simphysis mandible fracture in pediatric using erich arch bar. A 12 years old boy has fracture in mandible due to accident with mechanisme the chin hit the touching motorcyle tank. Clinically, was a deformity at the anterior of mandible and malocclusion has occured. Patient also complaint a  pain with swelling and bleeding at the regio of fracture and lip. Suturing was done  in wound area intra and extra oral, followed by application of arch bar in maxilla and mandible. Control at the third day was found a vague fracture line in panoramic radiograph. Management of emergency trauma in oral and maxillofacial surgery was based on principle of ATLS was done in this case. Following treatment was application of erich arch bar for mobility reducing the fracture of mandible symphisis. Management of mandibular symphisis fracture in 12 years old children with full eruption of teeth has been given a good healing  due to the teeth  was act to develop retention and stabilize the erich arch bar. Management of pediatric simphysis mandible fracture for 12 years old children with full eruption of teeth using erich bar revealed a healed fracture.

    Full Text Available The purpose of this study was to investigate the effects of 16 weeks of n-3 LC-PUFA (omega 3 long-chain polyunsaturated fatty acid supplementation on tennis skill acquisition in 10-12 year old girls. This research was a single-blind placebo-controlled trial. 29 girls (10-12 years of age who had never played tennis before took part in the study. Ball Throws to the Target (BTT and Tennis Ability Test (TAT were performed three times. Before participants were allocated to the groups and received n-3 LC-PUFA or olive oil, they underwent preparatory training for three weeks. Anthropometric measurements, nutrition analysis, and 1st BTT and TAT tests were performed and they continued the preparatory training until the 3rd week. Then they were randomly allocated to two groups to receive either n-3 LC-PUFA (omega group; 670 mg · day-1; n=16 or olive oil (placebo group; 670 mg · day-1; n=13 during 16 weeks of tennis training which involved 3 hours per week for 19 weeks. The results show that significant improvements in TAT were found in both groups but the omega group had significantly higher scores than the placebo group at the 3rd measurements. Although there were no differences between groups at all measurements of BTT, the omega group showed significant improvement between the 1st and 3rd measurements. This study suggests that daily 670 mg n-3 LC-PUFA supplementation for 16 weeks might improve tennis ability test scores of 10-12 year old girls.

    Celiac disease (CD) is associated with thyroid autoimmunity and other autoimmune diseases. However, data are lacking regarding the relationship between thyroid autoimmunity and thyroid function, especially in regard to CD. Our aim was to investigate the impact of thyroid autoimmunity on thyroid function in 12-year-old children with CD compared to their healthy peers. A case-referent study was conducted as part of a CD screening of 12-year-olds. Our study included 335 children with CD and 1,695 randomly selected referents. Thyroid autoimmunity was assessed with antibodies against thyroid peroxidase (TPOAb). Thyroid function was assessed with thyroid stimulating hormone and free thyroxine. TPOAb positivity significantly increased the risk of developing hypothyroidism in all children. The odds ratios (with 95% confidence intervals) were: 5.3 (2.7-11) in healthy 12-year-olds, 10 (3.2-32) in screening-detected CD cases, 19 (2.6-135) in previously diagnosed CD cases, and 12 (4.4-32) in all CD cases together. Among children with TPOAb positivity, hypothyroidism was significantly more common (odds ratio 3.1; 95% CI 1.03-9.6) in children with CD (10/19) than in children without CD (12/46). The risk of thyroid dysfunction due to thyroid autoimmunity is larger for those with CD than their healthy peers. Our study indicate that a gluten-free diet does not reduce the risk of thyroid dysfunction. Further studies are required for improved understanding of the role of the gluten-free diet for the risk of autoimmune diseases in children with CD.

    Objective: To explore the clinical effects of retroperitoneal laparoscopic ureterolithotomy (RPLU) and flexible-ureteroscopic holmium laser lithotripsy (f-UHLL) for complicated upper ureteral calculi. Methods: A total of 45 cases of complicated upper ureteral calculi between March 2014 and January 2016 in Department of Urology, Affiliated Jiangyin Hospital of Southeast University Medical College were retrospectively analyzed, there were 32 males and 13 females, ranging from 27 to 45 years with an average age of (34.1±9.5) years. Of the 45 patients, 28 had ureteral distortion and 17 had concurrent ureteral stones in the lower or middle ipsilateral ureter. In those patients, 20 cases underwent f-UHLL, and 25 cases received RPLU. The stone size, operation time, hospital stay, stone clearance rates and postoperative fever rates between the two groups were compared with t test and χ(2)test. Results: The operation was successfully performed in all patients, no complications with leakage of urine or ureteral perforation occurred, and no significant difference in renal function between the two methods were founded in postoperative period. There was no significant difference in operation time((78.4±8.5) minuetes vs.(73.3±11.3) minuetes, t=0.61, P=0.67), time of double J tube removed ((33.8±3.4)days vs. (37.6±8.9) d, t=2.37, P=0.08) and ipsilateral renal glomerular filtration rates ((41.3±7.6)ml/minuetes vs.(40.5±7.1) ml/min, t=0.78, P=1.27) between the two groups. However, the hospitalization time ((5.9±1.7)days vs. (4.2±1.6) days, t=1.92, P=0.04), postoperative fever rates (4% vs.30%, χ(2)=5.72, P=0.03) and calculus clearance rates (100% vs. 75%, χ(2)=7.03, P=0.01) in RPLU were significantly higher than f-UHLL. Besides, 5 patients in the f-UHLL group had postoperative stone residue and were treated with extracorpore shock wave lithotripsy. Conclusions: Both RPLU and f-UHLL are safety and validity for complex upper ureteral calculi. RPLU can improve the rate of

    Digital textbooks are being used to reduce production and storage costs of printed copies, enhance usage, and include search capabilities, but the use of digital texts is not universally accepted. In 2001, the New York University College of Dentistry introduced a digital reference library, the VitalBook. Beginning in 2005, the college annually surveyed senior students and, from 2012, also surveyed alumni on their opinions and extent of use of the VitalBook. The aim of this study was to evaluate 12 years of students' perspectives and three years of alumni perspectives on the value of the VitalBook to their dental educational experience. Students were asked how frequently they used the VitalBook, if it was a good investment, if they would use it after graduation, and if they would recommend it to others. Alumni were asked the last three questions. This study reports the results from 4,105 students over 12 years (average response rate 95.3%) and 184 alumni over three years (average response rate 17.4%). The results indicated that students used the VitalBook on average 24% of their study time, but they were split regarding the other questions. The majority opinion in 2005 was negative on all questions. These opinions shifted to become more favorable to a peak in 2010, but declined since then to a more negative overall view of the VitalBook. A split opinion among students continued through 2016, with fewer recommending it although more considered it a good investment with plans to use it after graduation. Alumni mirrored their responses as students. These results suggest that, as more flexible and dynamic digitized reference systems emerge, the use of student-paid traditional digitized textbooks may become an even less favored choice.

This study involved 103 children (43 boys and 60 girls categorized into two groups: G1 (7 to 9 years old and G2 (10 to 12 years old. The flexitest protocol, active and passive, and the SAPO® were used to evaluate joint range of motion. A paired t test was applied to compare active and passive joint range of motion and an independent t test (p < .05 was used to compare active and passive range of motion between gender and age. Results showed that the passive joint ranges of motion of the lower limbs are higher than active motion (p < .001. Girls presented greater passive ankle flexion than boys did (p = .002. Children between 7 and 12 years of age presented similar standards of joint range of motion of low limb. Significant differences were found between passive and active angular range of motion in the hip, knee and ankle. There were no differences between boys and girls in the joint range of motion as well as among age groups.

    Background: This study was taken to assess the prevalence of deleterious oral habits among 6-12 year old school going children. Materials & Methods: A sample size of 832 children was finalized with simple random sampling technique including 444 males and 388 females. To get the demographic information and presence of harmful oral habits a closed-ended questionnaire was developed. Clinical evaluation was also done using mirror and water tests. Chi-square test was done to compare the prevalence of oral habits among different age groups and gender at pBruxism (17.3%) was most commonly seen followed by bottle feeding (10.1%), thumb sucking (8.7%), nail biting (5.8%), tongue thrusting (4.9%) and mouth breathing (4.3%). Prevalence of all deleterious habits were more among female children and it also showed significant differences according to age. Conclusion: The data showed high prevalence of these oral habits. This highlighted the need for preventive orthodontic treatment at early age of life so that future occurrence of malocclusion can be avoided.

    Childhood obesity is a multifactorial disease, in which unhealthy dietary patterns and sedentary lifestyles play a decisive role. The aim of this study was to assess the weight status, dietary habits and physical activity in Castile-La Mancha children. A cross-sectional study was conducted on 3061 children 6-12 years-old who were participating in the programme, "Alimenta su salud". Anthropometric measurements, food consumption frequency, dietary habits and physical activity were assessed by a questionnaire, including gender, age and geographical influences. The prevalence of subjects with excess weight-for-height was 24.0% and obesity was 14.3%, with geographical differences. Girls more often have mid-morning snacks, consume more supplements, and reported to be less active than boys. Special diets and sports activities were lower in children aged 6-9 years as compared to the 10-12 years old group. The intake of vegetables and fruit is low, while there is overconsumption of sausages, pastries, salted snacks, sweets and fast food, with some differences by age group. One out of four children is overweight or obese in this population. Children do not meet recommendations for fruit and vegetables and there is a high consumption of foods associated with obesity risk. Physical inactivity was more prevalent during the weekends, and among girls. Copyright © 2010 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

    Full Text Available A 12-year sea-state hindcast for Taiwanese waters, covering the period from 2005 to 2016, was conducted using a fully coupled tide-surge-wave model. The hindcasts of significant wave height and peak period were employed to estimate the wave power resources in the waters surrounding Taiwan. Numerical simulations based on unstructured grids were converted to structured grids with a resolution of 25 × 25 km. The spatial distribution maps of offshore annual mean wave power were created for each year and for the 12-year period. Waters with higher wave power density were observed off the northern, northeastern, southeastern (south of Green Island and southeast of Lanyu and southern coasts of Taiwan. Five energetic sea areas with spatial average annual total wave energy density of 60–90 MWh/m were selected for further analysis. The 25 × 25 km square grids were then downscaled to resolutions of 5 × 5 km, and five 5 × 5 km optimal areas were identified for wave energy converter deployments. The spatial average annual total wave energy yields at the five optimal areas (S1–(S5 were estimated to be 64.3, 84.1, 84.5, 111.0 and 99.3 MWh/m, respectively. The prevailing wave directions for these five areas lie between east and northeast.

    The aim of the study is to assess smoking behaviour, knowledge of cigarette brands and access to cigarettes among children 8-12 years old in the Czech Republic. Between 2009 and 2012, a cross sectional survey was conducted among 4,439 children aged 8-12 years attending 51 primary schools in Prague and Central Bohemia, Czech Republic. Data including age, gender, ever smoking, parental and sibling smoking, knowledge of cigarette brands, sources of cigarettes, and smoking frequency were collected. Fifty nine percent of all children could name one or more cigarette brands, 62.8% of boys and 55.3% of girls (pbrands were Marlboro and the local brand Petra. Marlboro was better known among boys, while Petra was more known among girls. Children whose parents smoke showed higher brand awareness than children with non-smoking parents, 72.5% and 45.6%, respectively (pbrand awareness and ever smoking provide evidence that tobacco control policies in the Czech Republic do not adequately protect children. Tougher legislation and effective strategies in accordance with the WHO Framework Convention on Tobacco Control are therefore required to better protect children from harmful effects of smoking and the influence of tobacco industry in the Czech Republic.

    This study investigated the development of multitasking ability across childhood. A sample of 65 typically developing children aged 7, 9, and 11years completed two multitasking tests across three time points within a year. Cross-sectional and longitudinal data consistently indicated continuous linear growth in children's multitasking ability. By the age of 12years, children could effectively perform a simple multitasking scenario comprising six equally important tasks, although their ability to strategically organize assorted tasks with varied values and priorities in a complex multitasking setting had not reached proficiency yet. Cognitive functions underlying a complex multitasking scenario varied in their developmental trajectories. Retrospective memory developed continuously from 7 to 12years of age, suggesting its supporting role in the development of multitasking. Planning skills developed slowly and showed practice effects for older children but not for younger children. The ability to adhere to plans also developed slowly, and children of all age groups benefited from practice. This study offers a preliminary benchmark for future comparison with clinical populations and may help to inform the development of targeted interventions. Copyright © 2017 Elsevier Inc.

    The objective of this study was to assess the association between oral health-related quality of life (OHRQoL), measured through the Child-OIDP, and demographic characteristics, self-reported oral problems, and clinical oral health measures, among 11- to 12-year-old school children in the city of Rio de Janeiro, Brazil. A cross-sectional study was conducted, having as its target population 11- and 12-year-old students of both sexes, formally enrolled in 6- and 7-year school classes at public schools. A probabilistic sample with complex design was used. OHRQoL was assessed by the Brazilian version of Child-OIDP. Oral exams were conducted, and the presence of dental biofilm, gingival bleeding, DMFT, fluorosis, enamel defects, dental trauma, and malocclusion were recorded. A total of 571 school children participated with a mean age of 12.0 years and 95% confidence interval (95% CI) from 11.9 to 12.1. A total of 88.7% of the school children presented the impact of oral problems in at least one of the eight daily performances. The activities that had most impacts were eating (81.3%), cleaning mouth (40.5%), and smiling (32.2%). The mean Child-OIDP index was 7.1 with 95% CI from 6.2 to 8.1. The highest scores were in relation to eating (mean = 25.0; 95% CI from 22.4 to 27.6), cleaning mouth (mean = 12.0; 95% CI from 9.1 to 14.9), and smiling (mean = 10.0; 95% CI from 7.5 to 12.5). In the logistic regression model, the Child-OIDP was associated with dental caries experience and with the perception of sensitive teeth, perception of gingival bleeding, and perception of inadequate position of the teeth. In the multinomial regression, we found that the odds of having higher levels of Child-OIDP were positively associated with dental caries experience. Self-reported dental caries, mobile milk teeth, tooth position, bleeding gums, and bad breath were associated with worst OHRQoL. It can be concluded that there is an association between dental caries experience and the Child

    Full Text Available A field experiment was performed in Southwest Germany to examine the effects of long-term reduced tillage (2000–2012. Tillage treatments were deep moldboard plow: DP, 25 cm; double-layer plow; DLP, 15 + 10 cm, shallow moldboard plow: SP, 15 cm and chisel plow: CP, 15 cm, each of them with or without preceding stubble tillage. The mean yields of a typical eight-year crop rotation were 22% lower with CP compared to DP, and 3% lower with SP and DLP. Stubble tillage increased yields by 11% across all treatments. Soil nutrients were high with all tillage strategies and amounted for 34–57 mg kg−1 P and 48–113 mg kg−1 K (0–60 cm soil depth. Humus budgets showed a high carbon input via crops but this was not reflected in the actual Corg content of the soil. Corg decreased as soil depth increased from 13.7 g kg−1 (0–20 cm to 4.3 g kg−1 (40–60 cm across all treatments. After 12 years of experiment, SP and CP resulted in significantly higher Corg content in 0–20 cm soil depth, compared to DP and DLP. Stubble tillage had no significant effect on Corg. Stubble tillage combined with reduced primary tillage can sustain yield levels without compromising beneficial effects from reduced tillage on Corg and available nutrient content.

    This is the first reported case of bilateral sleeve fractures of the patellae in a child with crouch gait. A 12-year-old boy with hereditary spastic paraparesis (HSP), who was found to have mid-stance crouch of 20° on previous gait analysis, presented with pain of gradual onset and limited mobility. There was no history of trauma. Three-dimensional gait analysis showed that extensor mechanism function during loading response was intact, but knee flexion in swing was significantly reduced, indicating protective guarding by rectus femoris. X-rays showed bilateral minimally displaced sleeve fractures of the patellae. These were treated with immobilisation in cylinder casts in extension for 4 weeks. Follow-up X-rays showed that the fractures had successfully united and the patient progressed to full weight bearing and mobility as tolerated.

    The purpose of this study was to evaluate differences between how mothers and fathers monitor their children's sugar-sweetened beverages (SSBs; 7-12 years) using constructs from the integrated behavioral model (IBM). Mothers ( n = 167) and fathers ( n = 117) completed a valid and reliable survey evaluating the extent that they monitored their child's SSB intake and constructs of the IBM. Results showed significant differences between groups, with mothers consistently having higher levels of monitoring SSBs and IBM constructs. Regression models also showed that the core constructs of the IBM predicted a significant amount of the variance for monitoring SSBs for both mothers and fathers (39.4% and 18.3%, respectively), with intentions being the primary predictor for mothers and skillfulness the primary predictor for fathers. This study provides preliminary evidence that mothers and fathers monitor their children's SSB intake differently, and factors that determine monitoring SSB intake of children differ between mothers and fathers.

    Asthma is a common chronic disease. Asthma and anti-asthmatic medications have been suggested as risk factors for increased susceptibility to caries. This study was conducted to evaluate the effects of different types and forms of antihistaminic medications and the duration of drug consumption on the severity of dental caries in asthmatic children. This cross-sectional study was conducted in Asthma and Allergy Department of Children's Medical Center in Tehran, Iran. Eighty-five children between three to 12 years who had been diagnosed with asthma, by means of taking medical history, clinical examination and spirometry were chosen by non-simple random sampling. The participants and their parents were interviewed. Oral examination was performed by a qualified dentist. The data were collected by use of questionnaires and analyzed by the stepwise multivariate linear regression analysis, using SPSS version 16. Pdental caries even in presence of confounders (sex, age, duration of disease, tooth brushing, sugar consumption, fluoride therapy, mouth dryness).

    The principle of inclusive education has been increasingly recognised over recent decades and most countries officially support schooling of children with disabilities in mainstream settings. The SPARCLE study offers the opportunity to report on the schooling practices for children with cerebral palsy according to the nature and severity of their impairments and the schooling policy in European regions. The aim of this paper is to describe the type of schooling of children with cerebral palsy in various European regions after controlling for relevant individual factors. Children aged 8-12 years with cerebral palsy from 9 European regions and their families were interviewed. Our findings support the hypothesis that between-region variations in the type of schooling are still significant after adjustment for individual factors; and that motor function and intellectual ability have different effects on inclusion in mainstream school, depending on the region.

    In this study, we report the case of a 12-year-old male with X-linked ichthyosis (XLI) in association with glomerular sclerosis, and our investigation into the deletion pattern of the STS gene and the flanking regions in DNA samples of family members. We observed no features typical of renal osteodystrophy or rickets, with the exception of short stature, in the three afffected male family members. Audiometry, visual acuity and olfactory sensation were normal. By performing PCR analysis of the steroid sulfatase (STS) gene and flanking regions on our patients, we discovered a complete deletion that involved the entire region from DXS1139 to DXF22S1. Further studies are required to determine whether the STS gene or the co-deleted flanking sequences are the cause of renal disease associated with XLI.

    Between 1992 and 2003, a period of 12 years after the definitive ban on battery cages in Switzerland, more than 10,000 replacement chicks and laying hens were examined postmortem. There was a significant decrease in the incidence of viral diseases, mostly due to a reduction in Marek's disease, but there was a marked increase in bacterial diseases, particularly since 1999, mainly due to colisepticaemia in young laying hens. There was a steady decrease in parasitic infections, but the incidence of non-infectious diseases varied from year to year, with no clear trends. There were no significant emerging diseases or economic losses in the alternative housing systems. Vaccination and hygiene were the most effective precautions against infections, and control strategies brought about a marked decline in notifiable diseases, especially for Salmonella Enteritidis. Fifteen years after the ban on battery cages in Switzerland, the health and egg production of laying hens is good.

    The major effect of weightbearing exercise on adult bone mass may be exerted during childhood. We examined the relationship between reported hours of ballet classes per week undertaken as a child and adult bone mineral density (BMD) at the hip, spine, and forearm. We performed a retrospective cohort study in 99 female retired dancers (mean age 51 years, SD 14 years) and 99 normal controls, derived from a twin study, matched hierarchically for age, height, weight and menopausal status. Starting age of ballet was recalled and weekly hours of ballet as a child was self-reported on two occasions. BMD was measured using dualenergy X-ray absorptiometry and reported as a Z-score. Self-reported hours of ballet class undertaken per week at each age between 10 and 12 years was positively associated with a difference in BMD between dancers and controls at both the femoral neck site (beta = 0.73, p = 0.001) and the total hip site (beta = 0.55, p ballet), measures of menstrual disturbance (age of menarche, history of irregular menses), dietary history (calcium intake as a child, adolescent or adult) or lifestyle factors (lifetime smoking, lifetime alcohol). Although starting age of ballet was negatively associated with weight-adjusted within-pair hip BMD difference, it was no longer associated after adjustment for weekly hours of ballet. There was no relationship between hours of ballet undertaken as a child and differences in BMD at the lumbar spine or upper limb, at any age. Our data suggest that classical ballet classes undertaken between the ages of 10 and 12 years are independently and positively associated with a difference in hip BMD between dancers and controls. The findings are consistent with the hypothesis that this age range identifies a stage of development when the proximal femur is particularly responsive to weightbearing exercise.

    To investigate the oral hygiene practice, the prevalence of dental plaque, gingivitis and calculus among 12-year-old Sudanese schoolchildren in Khartoum province, and to correlate the above to gender and educational level of parents. A total of 636 children 12 years of age, whose parents granted permission, were examined from public and private schools in different geographical locations representing different socioeconomic classes in Khartoum province. The variables of this study had been collected by a single examiner using a direct interview questionnaire and clinical examination with appropriate indices. The intraexaminer reliability was (Alpha = 0.9321). Regular brushing in 92.3%, irregular in 6.9% and no brushing in 0.8% of all children. The frequency of brushing was 81.4% once, 16.4% twice and 1.4% more than twice a day. For all children, 93.1% used the toothbrush while 3.9% used a Miswak. Concerning the technique of brushing, 14.3% brushed vertically, 82.7% brushed horizontally and only 2% brushed in a circular way. It was found that only 5.2% used other oral hygiene means (dental floss and tooth pick) for cleaning teeth. The results showed a high correlation between oral hygiene practices of the children and both parents' education (P = 0.001) as well as gender (P = 0.001). The mean of plaque index was (0.888), gingival index was (0.686) and calculus index was (0.107). In the entire sample these indices were found to differ significantly with sex (P = 0.000), parents' education (P = 0.000) and brushing practice (P = 0.000).) It was recommended that, providing intensive advice and supervision concerning oral hygiene practices through public and school health care is mandatory. Other studies for rural and urban areas of different age groups should be done for comparisons.

    Eye diseases with increasing mortality are common health problems that affect people of all ages and demographic backgrounds. In this study, we study the publication characteristics in international ophthalmic journals of the US, the UK, Germany, Australia, Japan, and China. Articles published in 53 ophthalmic journals from 2000 to 2011 were retrieved from the PubMed database. We recorded the number of articles published each year, analyzed the publication type, and evaluated the accumulated and average impact factors (IFs), and the distribution of articles in ophthalmic journals in relation to IFs. The characteristics of publication outputs from China and other top-ranking countries were compared. The total number of articles increased significantly during the past 12 years, with an increase of 51.0%. The growth in the annual number of articles from the US, the UK, Australia, and China showed a significantly positive trend. Publications from the US exceeded those from any other country and had the highest IFs, largest number of total citations of articles, and the most articles published in leading ophthalmic journals. During the past 12 years, China contributed 3.5% of the total publications, and the number of Chinese articles showed a more than 6-fold increase (from 99 to 605, R2 =0.947, P<0.001). The numbers of IFs and citations of articles originating in China were mostly lower than for other top-ranking counties. Research on ophthalmic journals has maintained an upward growing trend from 2000 to 2011. Chinese ophthalmology research has developed rapidly, but the gap still exists between China and other top-ranking countries for the advanced level of research.

    Generalized anxiety disorder (GAD) is a chronic and highly prevalent disorder associated with increased disability and mortality in the elderly. Treatment is difficult with low rate of full remission, thus highlighting the need to identify early predictors for prevention in elderly people. The aim of this study is to identify and characterize incident GAD predictors in elderly people. A total of 1711 individuals aged 65 years and above and free of GAD at baseline were randomly recruited from electoral rolls between 1999 and 2001 (the prospective ESPRIT study). The participants were examined at baseline and five times over 12 years. GAD and psychiatric comorbidity were diagnosed with a standardized psychiatric examination, the Mini-International Neuropsychiatry Interview on the basis of DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, fourth edition) criteria and validated by a clinical panel. During the follow-up, 8.4% (95% confidence interval=7.1-9.7%) of the participants experienced incident GAD, 80% being first episodes; the incident rate being 10 per 1000 person-years. The principal predictors of late-onset incident GAD over 12 years derived from a multivariate Cox model were being female, recent adverse life events, having chronic physical (respiratory disorders, arrhythmia and heart failure, dyslipidemia, cognitive impairment) and mental (depression, phobia and past GAD) health disorders. Poverty, parental loss or separation and low affective support during childhood, as well as history of mental problems in parents were also significantly and independently associated with incident GAD. GAD appears as a multifactorial stress-related affective disorder resulting from both proximal and distal risk factors, some of them being potentially modifiable by health care intervention.

    To assess the epidemiology and risk indicators for dental erosion among 12-year-old schoolchildren in South Brazil. A population-based cross-sectional survey was conducted in Porto Alegre, Brazil, using a representative sample of 12-year-old schoolchildren (n = 1,528). Dental erosion was recorded according to the Basic Erosive Wear Examination (BEWE) index. Parents answered questions on socio-economic status, brushing frequency and general health. Schoolchildren answered questions on dietary habits. Anthropometric data were collected. Statistical analysis included logistic and Poisson regression models. The prevalence of dental erosion was 15% [95% confidence interval (95% CI): 13.6-16.5], being mainly mild erosion. Boys [odds ratio (OR) = 1.57, 95% CI: 1.17-2.10], private school attendees (OR = 1.45, 95% CI: 1.01-2.06) and schoolchildren reporting the daily consumption of soft drinks (OR = 5.04, 95% CI: 1.17-21.71) were more likely to have at least one tooth with dental erosion. Gender [boys, rate ratio (RR) = 1.66, 95% CI: 1.28-2.17], type of school (private, RR = 1.89, 95% CI: 1.53-2.35), the consumption of soft drinks (sometimes: RR = 5.27, 95% CI: 1.46-19.05; daily: RR = 6.82, 95% CI: 1.39-33.50) and the daily consumption of lemon (RR = 1.49, 95% CI: 1.11-2.00) were significantly associated with the number of affected surfaces. The present study found a moderate prevalence of dental erosion among young schoolchildren, with mild erosion being the most prevalent condition. Socio demographic variables and dietary habits were associated with dental erosion in this population. © 2015 FDI World Dental Federation.

    Objectives: to evaluate whether total and differential WBC counts are altered in young obese patients (aged 6-12 years) and if a relationship exists between WBC counts and the severity of obesity as well as with CRP level. Materials and Methods: a group of 77 obese patients [32 males and 45 females] and 19 controls [7 males and 12 females] were studied. Total WBC count was performed by using an automatic blood cell counter. Blood cell morphology and WBC differential count were evaluated in Wright stained blood films. The plasma levels of CRP were evaluated by immunoturbidimetry. Results: obese participants presented with a statistically significant higher neutrophil percentage and CRP levels when compared to controls; the median CRP value was about 5 times higher than that observed in controls. Absolute neutrophil count and neutrophil/lymphocyte ratio were also higher in patients, though without statistical significance. The parameters that were statistically significant related with adiposity markers were neutrophil count and CRP levels. The neutrophil count was positively and statistically correlated with body mass index (BMI), BMI z-score, waist circumference and waist/height ratio, and also with CRP levels. In multiple regression analysis, the only variable that remained statistically associated with neutrophil count was CRP (neutrophil count = 2.612 + 0.439lnCRP; standardised coefficient/beta: 0.384, P=0.001). When performing multiple regression without CRP, the only variable that remained statistically associated with neutrophil count was BMI. Conclusions: our results demonstrated in obese patients aged 6-12 years, a significant change in the differential leukocyte count towards neutrophilia, together with a significant higher CRP concentration, and that absolute neutrophil count correlates with obesity markers and with CRP levels. Our data also indicate that neutrophil count, a current clinically used low-cost parameter, may be used as an obesity

    Full Text Available The high occurrence of overweight and obesity amongst children is a disturbing health problem worldwide. Possible causes of increasing childhood obesity are inactivity and energy imbalances. The aim of this study was to analyse the total energy expenditure (TEEand physical activity levels in 9-year-old – 12-year-old overweight and obese children during a weekday and a weekend day, as well as during a weekday morning and afternoon. Twenty-four 9-year-old – 12-year-old children (seven boys and 17 girls, of whom nine were overweight and 15 were obese, were selected from seven public primary schools for this study. Body mass index (BMI cut-off points were used to distinguish between overweight and obese. Each participant wore an ACTICAL™ monitor to determine their physical activity levels and TEE. It was found that the TEE of the children did not differ between a week day and a weekend day, although the TEE of the week day afternoon differed significantly from that of the weekday morning. Unlike the overweight children, none of the obese children met the requirements of 60 minutes of moderate-intensity physical activity per day. Strategies should be found to increase the activity levels of overweight and, especially, obese children, specifically during the mornings and over weekends.

    The study is going to investigate the fundamental frequency (F(0)) and perturbation measures of sustained vowels in 360 native Malaysian Malay children aged between 7 and 12 years using acoustical analysis. Praat software (Boersma and Weenink, University of Amsterdam, The Netherlands) was used to analyze the F(0) and perturbation measures of the sustained vowels. Statistical analyses were conducted to determine the significant differences in F(0) and perturbation measures across the vowels, sex, and age groups. The mean F(0) of Malaysian Malay male and female children were reported at 240±34.88 and 254.48±23.35Hz, respectively. The jitter (Jitt), relative average perturbation (RAP), five-point period perturbation quotient (PPQ5), shimmer (Shim), and 11-point amplitude perturbation quotient (APQ11) of Malaysian male children were reported at 0.43±0.26%, 0.25±0.16%, 0.26±0.15%, 2.48±1.61%, and 1.75±1.04%, respectively. As for female children, the Jitt, RAP, PPQ5, Shim, and APQ11 were reported at 0.42±0.22%, 0.25±0.14%, 0.25±0.13%, 2.47±1.53%, and 1.75±1.10%, respectively. No significant differences in F(0) were reported across the Malay vowels for both males and females. Malay females had significantly higher F(0) than that in Malay males at the age of 8, 10, and 12 years. Malaysian Malay children underwent the nonsystematic decrement in F(0) across the age groups. Significant differences in F(0) were found across the age groups. Significant differences in perturbation measures were observed across the vowels in certain age groups of Malay males and females. Generally, no significant differences in perturbation measures between the sex were observed in all the age groups and vowels. No significant differences in all the perturbation measures across the age groups were reported in both Malaysian Malay male and female children. Copyright © 2012 The Voice Foundation.

    Background Total knee replacement is the only surgical option to treat painful degenerative osteoarthritis, restore knee function, improve quality of life, and enable patients to return to sports activity. With an aging population expecting an active life after retirement, patients' expectations of improvement after surgery are increasing as well. In view of the growing demand for higher performance, exercise and athletic activity, clinicians have been increasingly forced to question how much athletic activity a patient may resume after total knee replacement, and what types of athletic activity seem to be acceptable. However, there is currently no consensus on the appropriate intensity of physical activity after total knee arthroplasty or how activity levels affect the rate of revision surgery. Patients, material and methods In a retrospective study with a follow-up period of 12 years, 130 patients were asked about their sport activities 22 months before and after total knee replacement. Based on their answers, the patients were divided into one sports group (group A) and one group without any sports activity (group B). Seven years after surgery the same patients were asked about their sports activity again, and 12 years postoperatively they were additionally asked about whether or not they underwent revision surgery. Results Twenty-two months after total knee replacement 88 (67.7 %) of the 130 patients practiced sports for a minimum of 3 times a week (group A), whereas 42 (32.3 %) patients reported that they practiced no sports (group B). In 2010 - 7 years postoperatively - 60 patients of group A and 27 patients of group B took part in the survey; their levels of sports activity had not changed over the previous 7 years. In 2015, 46 patients out of group A and 21 patients out of group B were questioned. We saw a revision rate of 15.2 % (7 out of 46 patients) in the group with continuous sports activity, whereas we found an increased revision rate

    Atrophy of the mesial temporal structures, especially the hippocampus, has been implicated in temporal lobe epilepsy. However, to date, there is very scant data regarding normal volumes of the hippocampus in the pediatric population. This is a pilot study to estimate the normal volumetric data for the Indian pediatric population between 6 and 12 years of age. We have also tried to understand whether age and gender have an effect on the hippocampal volumes in this age group. The study group comprised 20 children, 6-12-years old without history of epilepsy or other neurological deficits. There were nine boys and 11 girls. All scans were performed on a 1.5T GE echo speed scanner. 3D fast SPGR sequence was prescribed in the coronal plane. The images were post-processed on an Advantage Windows 3.1 workstation. Using an automated program, the same observer calculated the hippocampal area, in cubic centimeters, clockwise and anticlockwise. The clockwise/anticlockwise data were subjected to correlation analysis for detecting intra-observer agreement. The mean and SD for left and right hippocampal volumes were estimated. The lower and upper limits for normal hippocampal volumes were determined using 95% ({+-} 2SD) limits on either side of the mean. In order to understand the effect of age on various hippocampal volumes we performed regression analysis. Mann-Whitney's test was used to test the significance of differences for gender variations. Correlation analysis established that there was intra-observer agreement. In the Indian pediatric population we have found the mean right hippocampal volume (RHV) to be 2.75 cm{sup 3} and mean left hippocampal volume (LHV) to be 2.49 cm{sup 3}. Mean hippocampal volume was found to be 2.67 cm{sup 3} (SD=0.42). The upper and lower limits for hippocampal volumes were 3.51 cm{sup 3} and 1.83 cm{sup 3}, respectively, based on 95% ({+-} 2SD) limits on either side of the mean. There was no effect of age or gender on the hippocampal

    Gingivitis is a common oral health problem. Untreated gingivitis may progress to periodontitis, a common cause of tooth loss. The prevalence of gingivitis and calculus among Puerto Rican children is unknown. Understanding this prevalence can support early public health preventative strategies. This study aims to estimate the prevalence of gingivitis and calculus among 12-year-old Puerto Ricans by health region and to explore differences in distribution by school type (proxy for socio-economic status) and gender. A probability-based sample of 113 schools was selected proportional to enrollment size and stratified by health region, school type, and gender. Two trained examiners evaluated the presence of gingivitis and both supragingival and subgingival dental calculus. Gingivitis was defined as the presence of gingival bleeding upon gentle probing (BOP) in at least one site, and the extent of the problem was classified according to the percentage of teeth whose gingiva presented BOP (limited: 25-49% of the teeth tested; extensive: >50% of teeth tested). Logistic and linear regression models, adjusted for health regions, were used to compare gingivitis and calculus prevalence and extent between genders and school types. Gingivitis was found in 80.41% of the 1586 children evaluated. Urban-public schoolchildren had a slightly higher prevalence (83.24%) compared to private (79.15%, p = 0.16); those in rural-public (77.59%) and private schools had similar prevalence (p = 0.15). Extensive gingivitis was present in 60.81% of all children. The mean percentage of sites presenting BOP (BOP%) was 17.79%. Rural and urban public schoolchildren presented significantly higher BOP% compared to children from private schools (p = 0.0005, p = 0.002, respectively). Dental calculus was detected in 61.59% of the sample, boys presenting significantly higher (p = 0.005) total and supragingival calculus. Rural-public schoolchildren had a significantly higher prevalence of

    This report sheds light on a successful treatment in febrile infection-related epilepsy syndrome (FIRES) with the combined use of lidocaine and MgSO4. We report a 12-year-old previously healthy girl who experienced an upper respiratory infection with fever and headache for 2 days, then suddenly went into a coma followed by repetitive status epilepticus. All tests for CNS infection, metabolic and toxic diseases, and autoimmune encephalitis were negative. Hence, the diagnosis of FIRES was made. During 5 weeks of hospital treatment, various antiepileptic drugs were administered at different times without success. To achieve seizure control, we then attempted the use of lidocaine first, then followed by MgSO4. The SE was successfully controlled when lidocaine plus MgSO4 was introduced. At follow-up, almost no neurological sequelae remained. This is the first report describing the combined use of lidocaine and MgSO4 with successful treatment outcomes. This experience has indicated that even FIRES can be controlled if treated promptly with certain agents. However, more studies are needed to explore the mechanisms and effects of lidocaine and MgSO4 in FIRES.

    Full Text Available The nutcracker syndrome (NCS is a rare cause of haematuria. It embraces an extended nonpathognomonic spectrum of symptoms that imply a difficult diagnosis. Ultimately it may be associated with substantial morbidity and even life-threatening events. We report a rare cause if a 12-year-old boy who presented with a history of frequent intermittent episodes of painless constant haematuria. The cystoscopy showed a bloody urine ejaculate from the left ureter meatus. The Doppler ultrasonography showed turbulent pattern of venous blood flow of the posterior renal vein branch behind the aorta. The abdominopelvic computer tomography (apCT revealed left renal vein (LRV duplication with a dilated retroaortic branch, entrapped between the aorta and the vertebral column, promoting the renal nutcracker syndrome. The patient was initially hospitalized and managed with oral iron supplements and continuous saline bladder irrigation, not requiring additional treatment. The child is currently asymptomatic, with haemoglobin value returning to normal and therefore proposed to conservative management with close followup. The authors present a case report of episodic haematuria caused by a rare entity—posterior nutcracker syndrome with renal vein duplication.

    Full Text Available Background: Celiac disease (CD is an autoimmune disorder deriving from an aberrant adaptive immune response against gluten-containing grains in genetically predisposed subjects. In a number of patients, CD is associated with one or more other autoimmune diseases. Primary Addison’s disease (AD and CD may co-exist, although this association is relatively uncommon in children. In addition, it is not precisely defined whether a gluten-free diet influences the course of AD. Case presentation: A case of CD in a 12-year-old boy presenting as acute adrenal insufficiency is described here. A gluten-free diet had a significant therapeutic role in this case, wherein most of the clinical signs and symptoms of AD disappeared in a few days. In addition, the dosage of cortisol acetate, initially administered to treat the AD, was able to be rapidly reduced. Conclusion: This case highlights that CD can be associated with AD in children, and a gluten-free diet seems to positively influence the course of AD.

    Full Text Available Retention harvesting, an approach that intentionally retains legacy features such as mature overstory trees, provides options for achieving ecological objectives. At the same time, retained overstory trees may compete with the nearby recovering understory for resources, and much remains to be learned about potential trade-offs with regeneration objectives, particularly over extended time periods. We assessed the influence of aggregated retention (reserved mature overstory and understory patches versus intact forest on structure and productivity (standing biomass of the adjacent woody understory and regeneration 12 years after harvest in northern Minnesota, USA. Each site was dominated by Populus tremuloides Michx., a species that regenerates prolifically via root sprouts following disturbance. Overall, fewer differences than expected occurred between the effects of intact forest and aggregated retention on regeneration, despite the small size (0.1 ha of aggregates. Instead, harvest status and distance from harvest edge had a greater influence on structure and standing woody biomass. Proximity to aggregates reduced large sapling biomass (all species, combined relative to open conditions, but only up to 5 m into harvested areas. This suggests the trade-off for achieving productivity objectives might be minimal if managers use retention aggregates in this region to achieve ecological objectives and meet management guidelines.

    to evaluate the effectiveness of the Ponseti method in treating syndrome-associated (nonidiopathic) congenital talipes equinovarus. This was a retrospective consecutive review over a 12-year period in a tertiary centre of all patients with syndrome-associated talipes equinovarus treated with the Ponseti method. The primary outcome measure at the final follow-up was the functional correction of the deformity. There were 16 (28 feet) children, with an average follow-up of 7 years (range: 4-12). The average age at presentation was 6.1 (range: 2-17) weeks. Deformities were severe, with an average Pirani score of 5.0 (range: 3.0-6.0). Initial correction was achieved in all children, with an average of 6 (range: 4-9) Ponseti casts and a tendo-Achilles tenotomy performed in 21/28 (75%) feet. Satisfactory outcome at the final follow-up was achieved in 23/28 (82%) feet. The Ponseti method is an effective first-line treatment for syndrome-associated talipes equinovarus to achieve functional painless feet; children will often require more casts and have a higher risk of relapse.

    The World Health Organization (WHO) indicates that the consumption of alcoholic beverages at social gatherings is common in many parts of the world and can have negative health and social consequences. Early initiation of alcohol use is a major risk factor for the development of patterns of abusive consumption of alcohol. To analyze the expectations towards alcohol consumption and to identify the age of onset of alcohol use in school children between 8 and 12 years of age. The study was exploratory, descriptive and cross-sectional. Data were collected from February to March, 2016, at the elementary schools Prof. Claudio Cortés Castro and Manuel Prieto Diaz in the city of Villahermosa, Tabasco. The questionnaire of expectations towards alcohol for children was applied. Sample size was 203 children. Twenty eight percent of children had consumed alcohol once in life; mean age of consumption onset was between 8 and 9 years old. Most frequently, the drink was beer, mostly provided by the father in places of family life. Among alcohol consumption expectations, dimensions scoring higher were aggressiveness and sociability and the dimension scoring lower was that of negative states. With respect to expectations towards alcohol consumption, children think that consuming alcohol promotes aggressive behavior followed by swear words, disturbing other people and discussing with them. In contrast, there are situations produced by alcohol consumption that children fail to appreciate, such as sadness and shame.

    The objective of this study was to analyze the frequency and distribution of odontogenic tumors (OTs) in the Cappadocia region of Turkey, and to compare the findings with those reported in the literature. The records of the Oral and Maxillofacial Surgery and Pathology Departments at Erciyes University, with histologic diagnosis of odontogenic tumors (based on the World Health Organization classification, 2005), over a 12-year period, were analyzed. The relative frequency of different types of tumors was also analyzed and compared with the literature. OTs in the present study constituted 2.74% of all the 7,942 registered biopsies. A total of 218 cases of OTs were collected and reviewed. Of these, (94.04%) were benign and (5.96%) were malignant. The mandible was the most commonly affected anatomic location, with 170 cases (77.9%). Ameloblastoma with a predilection for the posterior mandible was the most frequent odontogenic tumor (30.28%), followed by keratocystic odontogenic tumor (19.5%), odontoma (13.4%), and odontogenic myxoma (8.5%). OTs are rare neoplasms and appear to show geographic variations in the world. In Cappadocia, Turkey, they are more common in the mandible, with ameloblastoma followed by keratocystic odontogenic tumors with the incidences observed in the present study being similar to those of previous studies from Asia and Africa, and in contrast to those reported from American countries.

    Full Text Available The prevalence of obesity and overweight has been increasing worldwide over the last few years. The purpose of this study was to estimate the prevalence of obesity and overweight in schoolchildren aged 7 to 12 years from a mid-sized city in southern Brazil, and to determine possible associations with socioeconomic status, aerobic fitness, dietary habits, and leisure activities (sedentary and physical activity. A cross-sectional study was conducted and 1,442 children were evaluated regarding body weight and height. Obesity was defined based on BMI for gender and age. Descriptive, bivariate and multivariate analyses were carried out between the independent variables and outcome. The prevalence of obesity and overweight was 8% (CI: 7.54-8.45 and 19.9% (CI: 19.62-20.17, respectively. Aerobic fitness (p< 0.000, PR=0.59, practicing out-of-school time sports (p=0.005, PR=1.41, sedentary habits (TV, video games and computer (p=0.004, PR=1.50, and high socioeconomic level (p< 0.000, PR=2.64 were significantly associated with obesity and overweight in the adjusted multivariate model. Dietary habits were directly associated with obesity and overweight, but did not remain in the final multivariate model. The prevalence of obesity and overweight in this population was high and should be a matter of concern to city health authorities.

    To examine differences in quality of life according to family structure in Spanish children for the first time, and to determine whether the quality of life of children with divorced parents differs according to perceived interparental conflict. A cross-sectional, descriptive study was carried out in 1,025 children aged between 8 and 12 years old, recruited from seven randomly-selected schools in the province of Alicante. Of the total sample, 861 children had married parents and 164 had divorced parents. The children completed the Child Health and Illness Profile-Child Edition and those with divorced parents also provided information on the current relationship between their parents. Quality of life was higher in children with married parents than in those with divorced parents, with higher scores in all dimensions. Children who reported conflict between their parents after the divorce had worse quality of life. These results confirm significant differences in quality of life according to family structure and revealed the relationship between children's self-perceived health and interparental conflict after divorce. We emphasize the importance of health professionals in providing guidance to divorced parents on preventing their children's health problems and facilitating adaptation to the new family situation.

    A healthy worker effect due to respiratory disability has been noted in the farming population, but other factors may also interfere. Little has been published about factors influencing the early cessation of work in self-employed dairy farmers. Two hundred and nineteen dairy farmers were included from a cohort constituted in eastern France in 1993-1994 with a 12-year follow-up. Spirometric data, personal, and farm characteristics were registered. Cox models with delayed entry in which age was the time-scale were applied to identify the baseline predictive factors of the early cessation of dairy farming. Working in a modern farm was protective against early cessation of dairy farming (hazard ratio: 0.36 [95% CI: 0.16-0.81]), especially in men. Having asthma was a predictive factor of early cessation, especially in women (hazard ratio: 16.12 [95% CI: 3.28-79.12]). The most predictive factors of early cessation of dairy farming were health related in women and farm related in men. Copyright © 2011 Wiley Periodicals, Inc.

    Although leisure activities benefit the mental health of the elderly population, the effect of changes in leisure activities on dimensions of depressive symptoms remains unclear. This investigation examined the influences of changes in intellectual, social, and physical activities between waves on four dimensions of depressive symptoms at follow-up. Random effects modeling was utilized with data from a nationwide longitudinal study conducted in Taiwan. The study data comprised 6,942 observations from 2,660 older adults over a 12-year period. The results suggested that changes in physical activities contributed to depressive symptoms which reflected positive affect in the later wave. Increased social activities between waves predicted higher positive affect and lower interpersonal difficulties scores at follow-up. Increased intellectual activities between waves did not substantially affect any domain of depressive symptoms. In contrast, declines in intellectual activities between waves predicted higher scores in three depressive symptoms domains, including depressed mood, somatic symptoms, and interpersonal difficulties. Engagement in a varied range of activities benefits mental health among elders more than participation in any single type of activity among elders. Reducing physical activities can lower positive affect, while the adverse effect may be balanced by increasing social activities. Also, the impact of decreasing intellectual activities on the interpersonal difficulties domain of depressive symptoms may be offset by increasing social activities. © The Author 2014.

    Staphylococcus aureus bloodstream infections (BSI) are a significant cause of morbidity and mortality in haemodialysis patients. This study describes a 12-year retrospective review of S. aureus BSI in a large haemodialysis centre in a tertiary referral hospital. The overall rate of S. aureus BSI was 17.9 per 100 patient-years (range 9.7-36.8). The rate of meticillin-resistant S. aureus (MRSA) BSI was 5.6 per 100 patient-years (range 0.9-13.8). Infective complications occurred in 11% of episodes, the most common being infective endocarditis (7.6%). Ten percent of patients died within 30 days of S. aureus being isolated from blood. Most cases of S. aureus BSI (83%) were related to vascular catheters. The provision of lower-risk vascular access, such as arteriovenous fistulae, and reduced use of intravascular catheters should be priorities in all haemodialysis units. Where alternative vascular access cannot be established, interventions to reduce the risk of catheter-related infections should be implemented to reduce morbidity and mortality in this vulnerable patient group.

    Refractive error is one of the leading causes of visual impairment in children. An analysis of risk factors for refractive error is required to reduce and prevent this common eye disease. To identify the risk factors associated with refractive errors in primary school children (6-12 year old) in Nakhon Pathom province. A population-based cross-sectional analytic study was conducted between October 2008 and September 2009 in Nakhon Pathom. Refractive error, parental refractive status, and hours per week of near activities (studying, reading books, watching television, playing with video games, or working on the computer) were assessed in 377 children who participated in this study. The most common type of refractive error in primary school children was myopia. Myopic children were more likely to have parents with myopia. Children with myopia spend more time at near activities. The multivariate odds ratio (95% confidence interval)for two myopic parents was 6.37 (2.26-17.78) and for each diopter-hour per week of near work was 1.019 (1.005-1.033). Multivariate logistic regression models show no confounding effects between parental myopia and near work suggesting that each factor has an independent association with myopia. Statistical analysis by logistic regression revealed that family history of refractive error and hours of near-work were significantly associated with refractive error in primary school children.

    Full Text Available Pseudotumor cerebri (PTC is defined by clinical criteria of increased intracranial pressure, elevated intracranial pressure with normal cerebrospinal fluid (CSF composition, and exclusion of other causes such tumors, vascular abnormalities, or infections. The association of PTC with levothyroxine (LT4 has been reported. A 12-year-old boy has been followed up for autoimmune thyroiditis under LT4. Family history was irrelevant for endocrine or autoimmune diseases. A TSH level of 4.43 μUI/mL (0.39–3.10 motivated a LT4 adjustment from 75 to 88 μg/day. Five weeks later, he developed horizontal diplopia, convergent strabismus with left eye abduction palsy, and papilledema. Laboratorial evaluation revealed elevated free thyroxine level (1.05 ng/dL [0.65–1.01] and low TSH, without other alterations. Lumbar puncture was performed and CSF opening pressure was 24 cm H2O with normal composition. Blood and CSF cultures were sterile. Brain MRI was normal. LT4 was temporarily discontinued and progressive improvement was observed, with a normal fundoscopy at day 10 and reversion of diplopia one month later. LT4 was restarted at lower dose and gradually titrated. The boy is currently asymptomatic. This case discloses the potential role of LT4 in inducing PTC. Despite its rarity and unclear association, PTC must be seen as a potential complication of LT4, after excluding all other intracranial hypertension causes.
