Infratentorial atypical choroid plexus papilloma in an adult: A case report and literature review

Atypical choroid plexus papilloma is classified as WHO (World Health Organization) Grade II subtype of choroid plexus tumor, and it has intermediate pathological features, prognosis, and clinical outcome rates between choroid plexus papilloma and choroid plexus carcinoma. These tumors are more common in children compared with adults and are usually located in the lateral ventricles. We present a case of an adult with atypical choroid plexus papilloma located in the infratentorial region. A 41?year?old woman underwent evaluation for headache and dull aching neck pain. Magnetic resonance imaging (MRI) of the brain revealed a well?defined intraventricular mass lesion in the fourth ventricle and foramen of Luschka. She underwent craniotomy and gross total excision of the lesion. Histopathological and immunohistochemical findings confirmed the diagnosis of atypical choroid plexus papilloma (WHO Grade II). We discuss the various treatment options for this condition and review the relevant literature.

Differential Effect Of Family Disintegration On The Correlation Of Mental Health To Locus Of Control And Self-Efficacy Of Adolescents

The study aims to explore the relationship of mental health to internal locus of control and self-efficacy of adolescents, and further to explore the differential effect of family integration on the relationship. The descriptive correlational study collected data from a random sample of 1246 adolescent learners from different secondary schools of Kerala by administering standardized psychometric instruments. Statistical analysis brought out that both internal locus of control and self-efficacy of the adolescents from broken and intact families are significantly and positively correlated to their mental health. Significant differences were observed between adolescents from broken and intact families with respect to the correlation of mental health to internal locus of control and self-efficacy. Adolescents from broken families excelled their counterparts from intact families in the degree of relationship between the variables. The study revealed that the mental health of adolescents from broken families is more strongly influenced by their internal locus of control and self-efficacy than that of adolescents from intact families

DEMOGRAPHIC FACTORS AFFECTING COMMON ERRORS IN TENSE IN ENGLISH AMONG NINTH STANDARD STUDENTS

This descriptive study aims to find out the differential effect of gender, residential locale and medium of instruction on the errors made by the ninth grader students in the usage of English tenses. Three null hypotheses were tested by collecting data from a random sample of 291 ninth grade students from schools in Coimbatore district. The English Tense Error Analysis Test was administered to find out the common errors committed by the students in using the language. Independent sample t-test revealed significant differential effect of gender, residential locale and medium of instruction on common errors in English tense usage of ninth grade students. Boys compared to girls, rural students compared to urban students and Tamil medium students compared to English medium students make significantly high mistakes in English tense.

In vitro screening of multidrug resistance uropathogenic Escherichia coli from the urban area of Namakkal district

The aim of the study is to screen the multiple drug resistance (MDR) Uropathogenic Escherichia coli (UPEC) fromthe urban area of Namakkal district. To detect UPEC resistant by using different antibiotics and to analyze the virulentcharacteristics of UPEC and amplification of extended-spectrum beta-lactamases genes by multiplex polymerasechain reaction. Total 450 samples individually collected from the urinary tract infection (UTI) patients’ and directstreaked on to the eosin methylene blue agar plates. Significant growth indicates E. coli. HiCrome UTI agar was usedfor rapid identification of uropathogenic E. coli. Out of 450 samples, only 62 isolates of E. coli were subjected tovirulence characteristics, such as slime production (34%), hemolytic activity (56%), and beta-lactamase production(43%). Antibiotic sensitivity test was performed with 13 different antibiotics. Among them, 62 isolates were E. coli,only five were resistant to 10 antibiotics, possess virulence characteristics. Four strains (E-12, E23, E-58, and E-97)have Temoneira, sulfhydryl variable, and cefotaxime hydrolyzing capabilities (CTX-M) antibiotic resistance genes,and E-07 have only CTX-M gene. As E. coli is the main infectious agent in patients with UTI and a potent pathogen,it was difficult to treat with routine antibiotics because day-by-day microbes are resisting to common drugs. Hence,they need alternative therapy

Hemiarthroplasty in the Hip Fracture Patient with Renal Impairment: To Cement or Not to Cement / 대한고관절학회지

PURPOSE: Patients with chronic kidney disease (CKD) have a higher risk of complications when undergoing hip hemiarthroplasty. The primary aim is to test the null hypothesis that there is no difference between cemented and uncemented stem loosening rates in patients with CKD who receive a hip hemiarthroplasty for femoral neck fractures. The secondary aim is to determine the effect of increasing severity of renal disease on the rate of stem loosening in this CKD patient subset. MATERIALS AND METHODS: A retrospective study of all patients with CKD who underwent a hip hemiarthroplasty for a traumatic femoral-neck fracture between 2003 and 2013 was performed. Patients with a minimum of two-year follow-up were included; those with pathological fractures or loosening due to infection were excluded. The outcome measure was radiographic aseptic loosening of the stem, defined as progressive radiolucency of more than 2 mm, progressive subsidence or migration of the implant. RESULTS: One-hundred and nineteen cases were included in this study. Loosening occurred in 11 cases (9.24%). A comparison between cemented and uncemented groups revealed no difference in the rate of loosening (P=0.079). In all cases, worsening renal function did not increase the rate of loosening (P=0.311). The rate of loosening did not increase with worsening renal function in either the cemented (P=0.678) or uncemented groups (P=0.307). CONCLUSION: There is no difference in the rate of loosening between cemented and uncemented hemiarthroplasty for femoral neck fractures in the elderly with CKD. The rate of loosening did not increase with worsening renal function. All patients with renal impairment, not just those with end-stage renal failure, warrant close follow-up as early loosening can occur throughout the entire spectrum of renal disease.

Paraoxonase 1 status in keratoconus: a preliminary study of activity and polymorphism / Estatus de la paraoxonasa 1 en el queratocono: estudio preliminar de actividad y polimorfismo

OBJECTIVE: To determine the activity of paraoxonase 1 (PON1) in keratoconus in a Malaysian population in comparison with non-keratoconic subjects. METHODS: Clinical eye examinations were performed on patients with keratoconus and non-keratoconic subjects after questionnaires were completed. Blood samples were collected and subjected to spectrophotometry analysis of paraoxonase and diazoxonase activities for the determination of the status of PON1 of every individual. RESULTS: Of the 11 keratoconic patients and 55 non-keratoconic control samples collected, eight patients of Indian ethnicity were keratoconic (73%), whereas 33 non-Indians were non-keratoconic (60%; p = 0.047). Paraoxonase activity was lower in Indians compared to the non-Indians ie Malays and Chinese (p = 0.008). Keratoconic subjects had a lower paraoxonase activity compared to non-keratoconics (p = 0.038). CONCLUSIONS: The reduced paraoxonase activity in keratoconic patients suggests that the keratoconic corneas were more susceptible to oxidative stress. Reduced paraoxonase activity and keratoconus status appears to be associated with ethnicity.

OBJETIVO: Determinar la actividad de paraoxonasa 1 (Pon 1) en el queratocono en una población malaya, en comparación con sujetos no queratocónicos. MÉTODOS: Se realizaron exámenes clínicos oculares a pacientes con queratocono y a sujetos no queratocónicos luego que los mismos respondieran a los cuestionarios. Se recogieron muestras de sangre, que fueron entonces sometidas a análisis espectrofotométrico en relación con las actividades de la paraoxonasa y la diazoxonasa para la determinación del estatus de la paraoxonasa 1 de cada individuo. RESULTADOS: De los 11 pacientes queratocónicos y las 55 muestras de control no queratocónicas recogidas, 8 pacientes de etnicidad india fueron queratocónicos (73%), mientras que 33 no indios fueron no queratocónicos (60%; p = 0.047). La actividad de la paraoxonasa fue más baja en los indios en comparación con los no indios, es decir, los malayos y los chinos (p = 0.008). Los sujetos queratocónicos tenían una actividad de la paraoxonasa más baja, comparada con los no queratocónicos (p = 0.038). CONCLUSIONES: La actividad de la paraoxonasa reducida en los pacientes queratocónicos sugiere que las córneas queratocónicas son más susceptibles al estrés oxidativo. La actividad de la paraoxonasa reducida y el estatus del queratocono parecen estar asociados con la etnicidad.

Achalasia cardia with esophageal varix managed with endoscopic ultrasound-guided botulinum toxin injection.

Achalasia cardia is a motility disorder of the esophagus characterized by failure of relaxation of the lower esophageal sphincter. Nitrates and calcium channel blockers, pneumatic dilatation, botulinum toxin injection and surgical myotomy have been described in literature as possible management options. We present a patient who presented with achalasia and was co-incidentally diagnosed to have cryptogenic cirrhosis with portal hypertension and had esophageal varices. This clinical combination precluded the use of pneumatic dilatation and surgical myotomy.We injected botulinum toxin into the lower esophageal sphincter using a celiac plexus neurolysis needle under endoscopic ultrasound guidance; the clinical response was good.

Larvicidal and pupicidal activity of spinosad against the malarial vector Anopheles stephensi

OBJECTIVE@#To investigate the larvicidal and pupicidal activity of spinosad against Anopheles stephensi Listen.@*METHODS@#Spinosad from the actinomycete, Saccharopolyspora spinosa was tested against Anopheles stephensi at different concentrations (0.01, 0.02, 0.04, 0.06 and 0.08 ppm.), and against first to fourth instar larvae and pupae.@*RESULTS@#The larval mortality ranged from 36.1±1.7 in (0.01 ppm) to 79.3±1.8 (0.08 ppm) the first instar larva. The LC(50) and LC(90) values of first, second, third and fourth instar larva were 0.001, 0.031, 0.034, 0.036 and 0.0113, 0.102, 0.111, 0.113, respectively. The pupal mortality ranged from 33.0±2.0 (0.01 ppm) to 80.0±0.9 (0.08 ppm). The LC(50) and LC(90) values were 0.028 and 0.1020, respectively. The reduction percentage of Anopheles larvae was 82.7%, 91.4% and 96.0% after 24, 48, 72 hours, respectively, while more than 80% reduction was observed after 3 weeks.@*CONCLUSIONS@#In the present study spinosad effectively caused mortality of mosquito larvae in both the laboratory and field trial. It is predicted that spinosad is likely to be an effective larvicide for treatment of mosquito breeding sites.

Prevalence and manifestations of water-born fluorosis among schoolchildren in Kaiwara village of India: a preliminary study

Background: Fluorosis is an endemic condition with prevalence in 19 states and union territories in India. It is an urgent task to survey the fluorosis-related problems in these regions. Objective: To study the clinical manifestations of water-born fluorosis among schoolchildren in Kaiwara village of India. Methods: A cross-sectional study was conducted in all schoolchildren between 1st and 7th standard studying in Kaiwara village, Karnataka State, India. Parameters studied included fluoride ingestion through drinking water, fluoride excretion through urine, clinical features of fluorosis. These included dental staining, genu valgum, goiter, and conjunctival xerosis. Fluoride in water and urine samples was estimated using an ion meter. Results: Of the 416 schoolchildren studied, 24.0% children had dental fluorosis, 11.4% children had genu valgum, 20.9% had goiter, and 10.3% had xerosis of the conjunctiva. One hundred children passed high levels of fluoride in urine, while 90% of water samples consumed by the local residents contained high levels of fluoride. Conclusion: It was proved that water-born fluorosis is endemic in Kaiwara village. The endemic prevalence of the syndrome of fluorosis among school children was characterized by dental mottling, genu valgum, endemic goiter, and xerosis of the conjunctiva.

Communicable diseases monitored by disease surveillance in Kottayam district, Kerala state, India.

BACKGROUND & OBJECTIVES: A disease surveillance model developed in the North Arcot district, Tamil Nadu, was found to be practical, efficient, inexpensive and useful for public health action to monitor the success of ongoing interventions and to detect and intercept outbreaks. It was centred in the private (voluntary) sector with full co-operation and participation by the government sector. As Kerala state wanted to replicate this model in all districts, one district was chosen to pilot test it centred within the existing district public health system, soliciting participation from the private sector. A two-year (1999-2001) performance of this model is presented. METHODS: After elaborate preparations including the selection of 14 diseases to be reported and training of doctors in the private sector health care institutions and doctors and paramedical staff in all government health centres and hospitals, printed post cards were widely distributed. The business reply system was used so as to avoid handling postage stamps. Cards were received by the nodal officer in the district public health office and checked on a daily basis to detect disease prevalence and evidence of clustering in time and space. Swift action was taken on detecting case clustering. A monthly bulletin containing disease summaries and other useful information was freely distributed to all reporting centres. RESULTS: On an average, just over 100 disease reports were received every month. The most frequently reported diseases were, in the descending order, leptospirosis, acute dysentery, typhoid fever and acute hepatitis. Among vaccine-preventable childhood diseases, only measles was reported, but no diphtheria, tetanus or whooping cough. Several outbreaks were detected early and interventions applied to intercept them. The most striking example was that of cholera, the occurrence of which was detected swiftly for instituting highly successful control measures. INTERPRETATION & CONCLUSION: The district level disease surveillance system centred in the government public health system has been highly successful. Disease surveillance was responsible for the government to obtain information on the prevalence of leptospirosis in the district. The reports enabled the public health officers to detect disease-clustering as the early signals of outbreaks and to take quick remedial measures.
