Routing in Clustered Multihop, Mobile Wireless Networks With Fading Channel

A clusterhead-token infrastructure for multihop,mobile wireless networks has been designed. Traditional routing algorithms in wireline networks are not feasible for mobile wireless environment due to the dynamic change in link connectivity. To gain better performance for clustered multihop, mobile wireless networks, routing must take into account radio channel access, code scheduling, and channel reservation. In this paper, we propose some heuristic routing schemes for clustered multihop, mobile wireless networks. A packet delay improvement up to fourfold has been observed in our simulations comparedwith shortest-path scheme, making multimedia tra c viable. A radio channel model has been included to investigate the impact of channel fading on our protocols. To reduce the run time, a parallel simulator has been designed. Speedups of up to tenfold have been observed on a 16 processor SP/2.
Vascular repair is vulnerable to renal regeneration in early stage of diabetic nephropathy

Recent studies on vascular homeostasis in type 2 diabetic patients associated with altered serum creatinine concentration or presence of microalbuminuria have revealed an impaired mechanism of vascular repair, namely defective angiogenic factors, such as VEGF receptor 1, angiopoietin-1 in conjunction with abnormally elevated levels of anti-angiogenic factors such as VEGF receptor 2 and angiopoietin-2 [1]. Such impaired vascular repair explains: 1) reduction in renal perfusion observed in these patients, 2) unresponsiveness to vasodilators that are usually initiated at the late stage of diabetic nephropathy, resulting in therapeutic failure and progressive impairment of renal function towards end-stage renal disease. Under common practices, type 2 diabetic patients have generally been underestimated at the early stage (normal serum creatinine and normo-albuminuria), and usually been left unattended.
Comparison of intravenous lidocaine and midazolam infusion for refractory convulsive status epilepticus in children

Abstract Twenty children including nine boys and eleven girls with a mean age of 3.8 years (range: 0.1–;12 years) and admitted with a diagnosis of refractory convulsive status epilepticus constituted the study group. Ten children among them were treated with intravenous lidocaine (group 1) and other ten received midazolam infusion (group 2) for control of seizures. Variables such as age, sex, neuroimaging, electroencephalographic findings, concomitant fever, neurodevelopmental delay, complications, seizure control and length of stay (days) in the intensive care unit were carefully recorded. Two out of ten (20%) patients in group 1 responded while as five out of ten (50%) patients in group 2 responded (P = 0.1). No paraclinical side effects occurred in any patients in both the groups. Two patients needed intubation in group 1 as against seven in group 2 (P = 0.03). Mean length of stay in the intensive care unit was 4.6 days in group 1 and 9.2 days in group 2 (P = 0.04). No significant differences were seen with regard to age, sex, electroencephalographic findings, neuroimaging abnormalities or neurodevelopmental delay between the two groups. In conclusion, lidocaine can be used in refractory status epilepticus treatment especially when respiratory care and intubation facilities are not present.
Anorectal malformations - their impact on early phases in life

Abstract: Background : Anorecta l malformation s (ARM) occur in 4: 10000 newborn children with the gender distribut ion 1:1.5 females:males. The reconstruction of ARM, posterior sagiccal anorectal plasty (PSARP), was implemenred worldwide in the late 1980s and therefore the follow-ups are limited. Aims: To assess bowel symptoms in children and adolescents with ARM, operated on with PSARP, and to evaluate the qualicy oflife (QoL) and sexual health among the same adolescents. To evaluate the outcome of appendicostomy in preschool children with ARM. To study the anatomical status of the pelvic floor, and its possible correlation with bowel symptoms, among females with ARM. Results: Fecal incontinence was reported by 45% of the 121 children, and by 75% of the 24 adolescents. Constipation was reported by 50% children and 83% adolescents. Symptoms were more frequenr among females than males with the same subcype of ARM. Physically related QoL was lowered for females with ARM , while the mental domains in QoL were higher for the males with ARM compared with healthy conrrols. Jnrimate situations were influen ced by gas and fecal incontinence for both genders. Appendico stomy in 17 preschool children with ARM improved the fecal continence significand y, but 43% had minor complications. All 17 females with ARM examined with perineal ultrasonograph y had multiple defects on the anal sphincter, withour correlation with the degree of bowel symptom s. Conclusion: Bowcl symptoms in chi ldren and adolcscenrs with ARM arc considerable and gender differen ces arc present. "fhe QoL and sexual health are i nAuenced both by gas and feca l incontin ence, and by self-efficacy, so directed psychological support could be valuable. Appendicostomy in preschool children is successful and wi ll be continued. Al l pregnant females with ARM should preferab ly be recommended to deliver by cesarian section. (Less)

Approches archéométriques des productions faïencières françaises au XVIIIe siècle : le cas de la manufacture Babut à Bergerac (env. 1740 - 1789)

La faience est une ceramique caracterisee par son revetement vitreux blanc opaque, grâce a l’adjonction d’oxyde d’etain ; sur ce fond on peut apposer les decors polychromes. Resultant d’une technologie abbaside (VIIIe siecle), elle connait son apogee en France au XVIIIe siecle. Les precedentes etudes menees sur la faience moderne ont mis en evidence la necessite de proceder a une approche pluridisciplinaire pour apprehender ce materiau complexe, ses techniques de fabrication, et cerner les enjeux de sa production. Ce travail de recherche s’inscrit dans la continuite pour s’elargir aux productions faiencieres du Sud Ouest de la France quelques peu delaissees du point de vue archeometrique. La manufacture Babut, premiere faiencerie etablie a Bergerac, fut selectionnee dans ce but. La production perdure sur cinquante ans environ, jusqu’a la Revolution Francaise.En prenant en consideration ces observations, cette these a permis tout d’abord d’identifier la production du point de vue des materiaux et des techniques, de mettre en place un referentiel geochimique, ainsi qu’etablir un corpus stylistique de base pour cette manufacture. Ensuite l’etude a porte sur l’evaluation du potentiel de methodes d’analyses non destructives pour l’attribution de provenance directe a partir de la surface des glacures. Et enfin ce travail a permis d’examiner la place de la faience bergeracoise et de sa production au sein du tissu industriel regional, et les replacer dans le contexte plus general de la production faienciere francaise a l’aube de la Revolution industrielle.
Surgical Stabilisation of the Atlantoaxial Joint in a Cat

Summary A 15-month-old male exotic shorthair cat was presented to the Murdoch University Veterinary Hospital with a 13 month history of progressive ataxia and paresis. Radiography and myelography confirmed atlantoaxial instability and ventral compression of the spinal cord. Surgical stabilisation was achieved with two Kirschner wires and a bone graft via a ventral approach, and an external splint was applied for eight weeks. Four months postoperatively the cat had steadily improved, though neurological deficits were still present and arthrodesis of the atlantoaxial joint was not complete. Atlantoaxial subluxation has only rarely been reported in the cat. This is the third reported case of surgical correction, and a favourable prognosis was achieved in all three cases using a ventral technique. Cardiac arrest has been associated with both ventral and dorsal techniques, and is usually a fatal complication. Fortunately in this case the cat was successfully resuscitated and made a full recovery.
Evaluación de la satisfacción educativa de médicos residentes

La educacion medica moderna esta centrada en los alumnos y es pertinente valorar la satisfaccion educativa de los medicos en formacion. Se valido un cuestionario e investigo la satisfaccion educativa de los medicos residentes del Hospital General de Mexico. Objetivo: validar un cuestionario para evaluar la satisfaccion educativa de los medicos residentes del Hospital General de Mexico. material y metodos: Estudio observacional, descriptivo, transversal, prospectivo. Se valido un cuestionario de 21 reactivos, aplicado posteriormente a una muestra representativa de residentes. Cada reactivo se valoro ascendentemente de 0 al 10 de acuerdo con el grado de satisfaccion percibido: 0-5 = malo, 6-7 = regular, 8 = bueno, 9 = muy bueno, 10 = excelente. Se realizo estadistica descriptiva e inferencial de los resultados con el software SPSS version 17.0. resultados: El cuestionario tuvo validez interna con una alfa de Cronbach > 0.91 por reactivo. Participaron 355 residentes de las 37 especialidades. La percepcion del desempeno de los profesores titulares tuvo una amplia heterogeneidad: 23.7% de los residentes lo percibio como excelente, 20.6% como muy bueno, 16.9% como bueno, 23.1% como regular y 15.8% como malo. Los residentes de cuarto en adelante evaluaron mejor el desempeno docente (p = 0.001); lo mismo sucedio con los residentes de especialidades medico-quirurgicas (p = 0.02) y con los residentes de edad intermedia (p = 0.001) al igual que los no solteros (p < 0.001). Al contrastar la valoracion del desempeno del profesor y el desempeno global del curso se obtuvo una correlacion lineal, directa y significativa, con un coeficiente de relacion de Spearman de 0.78; el de regresion tuvo una p < 0.001. Conclusiones: Existio gran heterogeneidad de resultados. El desempeno de los profesores fue el componente primordial para juzgar la calidad de los cursos
The processing of derivations in native and non-native speakers of Dutch

The processing of morphologically complex verbs was investigated in native and German non-native speakers of Dutch. Both semantically transparent derivations (in which the meaning of the whole can be derived from the meaning of the parts; e.g., opschrijven ‘write down’ with stem schrijven ‘write’) and semantically opaque derivations (e.g., toegeven ‘admit’ with stem geven ‘give’) were presented. These derivations had either a motor-related stem (i.e., referring to an action requiring the use of certain muscles, e.g., schrijven ‘write’) or a non-motor stem (e.g., kiezen ‘pick’, as in uitkiezen ‘pick out’). Two studies using functional magnetic resonance imaging showed activation of the same brain areas for both groups when they read these words: morphologically primed transparent derivations led to repetition suppression effects in the left inferior frontal gyrus, suggesting they were decomposed; opaque derivations with a motor stem did not lead to increased activation in the motor cortex, suggesting they were processed holistically. These results indicate that German non-native speakers process Dutch derivations similarly to native speakers. The stems of these derivations, when presented separately, were also processed in a similar way: in both groups, reading motor verbs like schrijven (‘write’) led to increased activation in the motor cortex. Further research using behavioral priming in native speakers of Dutch showed that transparent derivations containing a motor verb as their stem (e.g., opschrijven) elicited priming effects, in contrast with other types of derivations (e.g., uitkiezen or toegeven), possibly due to stronger activation of the meaning of motor words. However, this was only the case in a priming context emphasizing semantic relations. Thus, the processing of derivations seems to be flexible: it does not only depend on the verbs themselves, but also on the context in which they appear. Results were interpreted in the context of embodied cognition and models of derivation processing.
Child Sexual Abuse in Minna, Niger State Nigeria

Background: Child sexual abuse is a widespread form of child abuse that has remained the most under-reported. In our communities, much remains unknown of this act which often leaves victims traumatised with unsavoury memory that tends to affect their psychosocial development. The study evaluted the socio-demographic features and the nature of sexual abuse as seen in the outpatient department of general hospital Minna, Niger state. Patients and Methods: The case notes of patients who presented to the General Out-patient Department (GOPD) of General Hospital Minna were analysed for cases, of sexual assault, sexual abuse or rape seen between January 2008 and December 2008. Results: A total of 32 cases were seen, 90.1% of whom were children less than 17 years old; 75% were aged 6 - 15 years. All the cases were of the penile penetrative type (vaginal in girls and anal in boys). All the perpetrators were adult males known to, and resident in, the neighbourhood of their victims. Conclusion: There is need to build the capacity of health care providers to enable them manage child sexual abuse and its long-term effects in Minna.

Mood and cognitive side effects of interferon-α therapy

Abstract The central nervous system side effects associated with interferon-alpha (IFN-alpha) therapy, including depression and cognitive changes, can compromise otherwise effective immunotherapy. The term "depression" has multiple meanings ranging from a feeling of sadness to a neuropsychiatric disorder with defined diagnostic criteria. A syndrome of mood disturbance with memory impairment, cognitive slowing, and impaired executive function is common with IFN-alpha therapy and is consistent with mild subcortical dementia. Cognitive deficits and mood disorder may occur independently, and in some cases depression is a reactive phenomenon. Risk factors for development of IFN-alpha neurotoxicity include duration of treatment, high-dose therapy, and prior cranial irradiation or neurologic illness. Past or current psychiatric illness also may put the patient at risk. Subtypes of major depression are associated with neuroendocrine and neurochemical alterations that are consistent with the observed activities of IFN-alpha. This may provide insight into the etiology of IFN-alpha neurotoxicity, as well as possible interventions. Assessment of the neuropsychiatric status of patients treated with IFN-alpha should be a standard of care. Possible pharmacologic interventions to decrease the neurotoxicity associated with IFN-alpha therapy include antidepressants, psychostimulants, and opioid antagonists. Preliminary clinical and research experience suggests that it is possible to effectively palliate IFN-alpha toxicity.
ORAL HEALTH: KNOWLEDGE AND PRACTICES IN RURAL COMMUNITY

Background: Good oral health is a key for ensuring overall well-being. Dental caries and periodontitis may also be linked to different systemic diseases. Good oral health practices are the clue for preventing the diseases of the oral cavity. Objectives: To assess the oral health knowledge and oral health practice of the people in a rural community. Materials and Methods: Study was conducted in Dehradun district of Uttarakhand state. Sample population has been selected based on systematic random sampling. Study has included 798 participants above 3 years of age. Statistical Analysis Used: Percentage. Results: Study results have shown poorest oral health status amongst population below 19 years of age. Constant pain in teeth/ gums was also reported maximum in this age group. Habit of having sticky food was reported maximum in 3-10 years age group with poorest practice of brushing teeth (daily brushing was reported by only 67% population and twice a day was reported by only 2.4%.). Discussion: Study results have shown that perception of having good oral health is high in this population but oral health practices are not satisfactory. Conclusion: Study finding recommends that oral health awareness needs to be increased in the area especially focusing young children. Awareness programs should be supplemented with primary care services for better oral health and hygiene.
Cardiovascular Monitoring and Substitution of the Blood Volume During Liver Transplantation

Orthotopic liver transplantation (OLT) became a treatment modality in Denver (Starzl et al., 1963) and Cambridge, England in 1968 (Calne, 2008) although exposing critically ill patients to extensive surgery was a challenge and in the 1970s, the one year survival rate remained in the vicinity of only 25% (Starzl et al., 1981). One problem was to manage the often impressive blood loss and rapid infusion devices were developed to provide large amounts of blood products at body temperature (Stammers et al., 2005). During OLT the blood loss has, fortunately, declined and in the 1980s, the average number of blood units administered was reduced to 20 and in some centres, ~ 80% of patients are now without a need for administration of blood (Massicotte et al., 2004). Yet, there remains differences among centres and for a number of patients, OLT is associated with a significant blood loss (Massicotte et al., 2004). Furthermore, haemodynamic challenges are inevitable during the operation. Corresponding to the metabolic activity of the liver, the hepatectomy is likely to reduce cardiac output (CO) and in cases for which caval and portal clamping are used, blood accumulates in the splanchnic region and in the lower part of the body which together leads to a decline in CO by 40%-50% (Ozier & Klinck, 2008). Conversely, CO often doubles during reperfusion of the grafted liver as peripheral vasodilatation is provoked by the release of blood from the splanchnic region mixed with the chilled outflow from the liver, potentially with a high potassium concentration (Ozier & Klinck, 2008). Also it may be that the heart is unable to respond with an adequate increase in CO to reperfusion of the grafted liver, or that there is a reduction in CO despite an, apparently, adequate central blood volume (CBV), accepting that reperfusion of the liver and re-establishing splanchnic blood flow may release some cardio-inhibiting factor (Jordan et al., 1999). Given redistribution of the blood volume during OLT, monitoring of the circulation is, ideally, directed to secure CBV rather than the total blood volume.

La transicin demogrfico-epidemiolgica en Chile, 1960-2001

Fundamento: En Chile se ha modificado de manera significativa la estructura demografica y las causas de morbilidad y de mortalidad de la poblacion en un periodo relativamente breve de tiempo. Estas variaciones se enmarcan dentro de los procesos denominados transicion demografica y transicion epidemiologica respectivamente. El proposito de este trabajo es evidenciar la transicion demografica y la transicion epidemiologica ocurridas en el pais entre 1960 y 2001. Metodo: Se trata de un estudio de series temporales que recoge informacion demografica y de mortalidad de Chile entre los anos 1960 y 2001. Los datos fueron obtenidos de los Anuarios de Demografia del Instituto Nacional de Estadisticas (INE), de informacion producida por el Departamento de Estudios Prospectivos del Ministerio de Planificacion y Cooperacion y del Ministerio de Salud de Chile. Resultados: En 1960 un 39,6% de la poblacion tenia menos de 14 anos, la tasa de natalidad era de 36,3 por 1000, la tasa de mortalidad general de 12,3 por 1.000 y la tasa de mortalidad infantil de 120 por 1.000. El 44% de la mortalidad general se generaba en causas infecciosas y perinatales. En el ano 2001 un 28% de la poblacion tiene menos de 14 anos, la tasa de natalidad es de 18,3 por 1.000, la tasa de mortalidad general de 5,4 por 1.000 y la tasa de mortalidad infantil de 8,9 por 1000. El 68% de la mortalidad general se produce por enfermedades cronicas. Conclusiones: En base a los resultados, es posible afirmar que Chile se encuentra en una fase tardia tanto de transicion demografica como de transicion epidemiologica. Conocer la realidad de Chile aportara informacion a aquellos paises de America Latina que se encuentren en fases mas tempranas de este tipo de transiciones.
