Society for Acute Medicine's Patients: Learning from Experience Report (SAM-PLER) A service evaluation of patient reported experience in Acute Medicine - establishing the feasibility of a quality improvement collaborative.

Patient reported experience measures (PREMS) are a key part of measured quality. There is no tool currently used in the UK in Acute Medicine. On the 8th of September 2022 10 units based in England, Scotland and Wales collected data for the validated PREM, alongside the EQ-5D and variables from the Society for Acute Medicine's Benchmarking Audit (SAMBA) dataset. 365 patients were screened, 200 were included (55%): 159 patients from AMUs and 41 from SDEC units. Overall experience of patients was rated 8.5/10, patients rated their experience of safety, trust and listening highly. Collection of PREMS was feasible. Further research is required to link experience to clinical outcome and explore tools that capture experience of patients with altered mental status.

An extendable optical fibre probe survey meter for naturally occurring radioactive material (NORM) and other weak emitters.

We have developed a radioluminescence-based survey meter for use in industries in which there is involvement in naturally occurring radioactive material (NORM), also in support of those needing to detect other weak emitters of radiation. The functionality of the system confronts particular shortcomings of the handheld survey meters that are currently being made use of. The device couples a LYSO:Ce scintillator with a photodetector via a polymer optical fibre waveguide, allowing for "intrinsically safe" inspection within pipework, separators, valves and other such component pieces. The small-diameter optical fibre probe is electrically passive, immune to electromagnetic interference, and chemically inert. The readout circuit is entirely incorporated within a handheld casing housing a silicon photomultiplier (SiPM) detection circuit and a microprocessor circuit connected to an LCD display. A 15 m long flexible PMMA optical fibre waveguide is butt coupled to an ABS plastic probe that retains the LYSO:Ce scintillator. Initial tests have included the use of lab-based mixed gamma-ray sources, measurements being made in concert with a reference conventional GM survey-meter. Characterization, via NORM sources at a decontamination facility, has shown useful sensitivity, covering the dose-rate range 0.10- to 28 µSv h-1 (R-squared 0.966), extending to 80 µSv/h as demonstrated in use of a Cs-137 source. The system is shown to provide an effective tool for detection of radioactivity within hard to access locations, in particular for sources emitting at low radiation levels, down to values that approach background.

Dientamoeba fragilis associated with microbiome diversity changes in acute gastroenteritis patients.

This study examined the correlation between intestinal protozoans and the bacterial microbiome in faecal samples collected from 463 patients in New Zealand who were diagnosed with gastroenteritis. In comparison to traditional microscopic diagnosis methods, Multiplexed-tandem PCR proved to be more effective in detecting intestinal parasites. Among the identified protozoans, Blastocystis sp. and Dientamoeba fragilis were the most prevalent. Notably, D. fragilis was significantly associated with an increase in the alpha-diversity of host prokaryotic microbes. Although the exact role of Blastocystis sp. and D. fragilis as the primary cause of gastroenteritis remains debatable, our data indicates a substantial correlation between these protozoans and the prokaryote microbiome of their hosts, particularly when compared to other protists or patients with gastroenteritis but no detectable parasitic cause. These findings underscore the significance of comprehending the contributions of intestinal protozoans, specifically D. fragilis, to the development of gastroenteritis and their potential implications for disease management.

Point of care ultrasound: Current and future directions for Acute Medicine.

Point of care ultrasound (POCUS) represents an exciting tool for current and future acute care practitioners. POCUS has come a long way in a short space of time and its widespread implementation may well be one of the biggest changes seen in acute medicine across the next decade. This narrative review explores the increasing evidence base for the accuracy of POCUS use in various acute scenarios, whilst also addressing current gaps in the evidence and areas for potential future POCUS development.

Awareness and Practice of Laparoscopic Surgery among Trainee Surgeons in Nigerian Tertiary Hospitals.

BACKGROUND: The advent of laparoscopy has been a notable landmark in surgery; however, there is a slow progress to widespread utilization in West Africa. AIMS: To study the awareness and practice of laparoscopic surgery among trainee surgeons in Nigerian tertiary hospitals while highlighting measures to mitigate challenges. MATERIALS AND METHODS: A cross-sectional study conducted during a 2-week West African College of Surgeons update course in September 2018 at Ilorin, Kwara State, Nigeria. A structured questionnaire was distributed to registered trainee surgeons for completion. Data collated included demographics, cognitive knowledge, common procedures in centres, referrals, routine practice, performing laparoscopic surgeon, and routine practice. Statistical analysis was done using IBM SPSS Statistics for Windows version 20 Armonk NY USA. RESULTS: There were 184 registered trainee surgeons with 80 respondents from 26 Nigerian tertiary health facilities. The age range was 29 -51 years (mean 35.0 ± 4.4) and a mean training duration of 3.3 years (R2= 0.12). Seven (63.6%) senior registrars and 54(76.3%) registrars were reported as first assistants in laparoscopic surgeries performed but no unassisted surgery. Four (15.4%) represented centres had no laparoscopy equipment or expertise. A non-referral rate of 52/80(65.0%) for laparoscopic surgery was recorded. CONCLUSION: Laparoscopic surgery is practiced in some Nigerian tertiary hospitals with trainee surgeons actively involved in performing these surgeries. However, there is limited unassisted experience by trainee surgeons in the basic laparoscopic surgeries predominantly performed.

CONTEXTE: L'avènement de la laparoscopie a été un jalon notable en chirurgie; cependant, il y a un lent progrès vers une utilisation généralisée en Afrique de l'Ouest. OBJECTIFS: Étudier la sensibilisation et la pratique de la chirurgie laparoscopique chez les chirurgiens stagiaires dans les hôpitaux tertiaires nigérians tout en mettant en évidence les mesures visant à atténuer les défis. MATÉRIEL ET MÉTHODES: Une étude transversale menée au cours d'un cours de mise à jour de 2 semaines du Collège ouest-africain des chirurgiens en septembre 2018 à Ilorin, État de Kwara, Nigéria. Un questionnaire structuré a été distribué aux chirurgiens stagiaires enregistrés pour qu'il le remplisse. Les données rassemblées comprenaient les données démographiques, les connaissances cognitives, les procédures courantes dans les centres, les références, la pratique de routine, le chirurgien laparoscopique en exercice et la pratique de routine. L'analyse statistique a été effectuée à l'aide d'IBM SPSS Statistics pour Windows version 200 Armonk NY USA. RÉSULTATS: Il y avait 184 chirurgiens stagiaires enregistrés avec 80 répondants de 26 établissements de santé tertiaires nigérians. La tranche d'âge était de 29 à 51 ans (moyenne 35,0 ± 4,4) et une durée moyenne de formation de 3,3 ans (R2 = 0,12). Sept (63,6%) registraires principaux et 54 registraires (76,3%) ont été signalés comme premiers assistants dans les chirurgies laparoscopiques effectuées mais pas de chirurgie non assistée. Quatre (15,4%) centres représentés n'avaient ni équipement ni expertise de laparoscopie. Un taux de non-référence de 52/80 (65,0%) pour la chirurgie laparoscopique a été enregistré. CONCLUSION: La chirurgie laparoscopique est pratiquée dans certains hôpitaux tertiaires nigérians avec des chirurgiens stagiaires activement impliqués dans la réalisation de ces chirurgies. Cependant, l'expérience non assistée des chirurgiens stagiaires est limitée dans les chirurgies laparoscopiques de base principalement pratiquées. MOTS CLÉS: Chirurgie, laparoscopie, formation.

Why has the caesarean rate increased dramatically in Bangladesh?

OBJECTIVE: The objective is to assess the reasoning by families in deciding between a home vs. facility delivery and vaginal vs. caesarean. STUDY DESIGN: The authors selected a convenience sample of 16 villages in Sathkira district in southwest Bangladesh. Evidence was drawn from detailed in-home post-delivery interviews with all mothers in these villages who delivered in 2015 or 2016. METHODS: Local family health workers and paramedics used a structured questionnaire that enabled gathering of relevant quantitative and qualitative evidence. Mothers' reasons for selection of delivery location and type were categorized, and regression analysis was conducted to assess significance of variables that proxy supply and demand factors. RESULTS: Among 492 completed interviews, 48% were home deliveries, 52% facility deliveries; two-thirds of facility deliveries in private clinics. Overall, sample caesarean rate is 39%, public hospital rate 53%, private clinic rate 86%. Over half of reasons for home delivery refer to pregnancy without complication or access to trusted birth attendant. Over half of reasons for facility delivery refer to medical complications allegedly precluding home delivery, or requiring home-to-facility transfer during labour for reasons not clear to the mother. The decision depends on both 'demand' factors originating with the family (proxied by family income, birth order and education levels) and 'supply' factors originating with obstetric care providers (proxied by number of antenatal visits and variation of caesarean rate by village). In a regression controlling for both demand and supply variables, the above proxy variables are all significant. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Bangladesh has inadequate nursing support for vaginal delivery in either home or facility. Hence, physicians frequently recommend that women deliver in a facility (usually a physician's clinic). Physicians are reluctant to hire adequate nurses to attend vaginal deliveries. Hence, families with some discretionary income are increasingly opting for a caesarean over vaginal delivery. Facility deliveries reduce incidence of obstructed labour fistula, but probably contribute to rising incidence of iatrogenic fistula. Reducing caesarean rates requires a large increase in numbers of nurses and midwives, and acceptance by physicians of a broad scope of practice for nurses/midwives in vaginal deliveries.

Loss-of-Function GRHL3 Variants Detected in African Patients with Isolated Cleft Palate.

In contrast to the progress that has been made toward understanding the genetic etiology of cleft lip with or without cleft palate, relatively little is known about the genetic etiology for cleft palate only (CPO). A common coding variant of grainyhead like transcription factor 3 ( GRHL3) was recently shown to be associated with risk for CPO in Europeans. Mutations in this gene were also reported in families with Van der Woude syndrome. To identify rare mutations in GRHL3 that might explain the missing heritability for CPO, we sequenced GRHL3 in cases of CPO from Africa. We recruited participants from Ghana, Ethiopia, and Nigeria. This cohort included case-parent trios, cases and other family members, as well as controls. We sequenced exons of this gene in DNA from a total of 134 nonsyndromic cases. When possible, we sequenced them in parents to identify de novo mutations. Five novel mutations were identified: 2 missense (c.497C>A; p.Pro166His and c.1229A>G; p.Asp410Gly), 1 splice site (c.1282A>C p.Ser428Arg), 1 frameshift (c.470delC; p.Gly158Alafster55), and 1 nonsense (c.1677C>A; p.Tyr559Ter). These mutations were absent from 270 sequenced controls and from all public exome and whole genome databases, including the 1000 Genomes database (which includes data from Africa). However, 4 of the 5 mutations were present in unaffected mothers, indicating that their penetrance is incomplete. Interestingly, 1 mutation damaged a predicted sumoylation site, and another disrupted a predicted CK1 phosphorylation site. Overexpression assays in zebrafish and reporter assays in vitro indicated that 4 variants were functionally null or hypomorphic, while 1 was dominant negative. This study provides evidence that, as in Caucasian populations, mutations in GRHL3 contribute to the risk of nonsyndromic CPO in the African population.

Effectiveness of Contour Augmentation with Guided Bone Regeneration: 10-Year Results.

In aesthetic sites, the integrity of the facial bone wall dimension in the anterior maxilla is jeopardized by physiologic and structural changes postextraction. An effective regenerative protocol is key to reestablish and maintain the hard and soft tissue dimensions over time. The present prospective case series study examined the effectiveness of early implant placement with simultaneous contour augmentation through guided bone regeneration with a 2-layer composite graft in postextraction single-tooth sites over an observation period of 10 y among 20 patients. The median peri-implant bone loss was 0.35 mm between the 1- and 10-y examination. A success rate of 95% was obtained, with pleasing aesthetic outcomes and a high median Pink Esthetic Score (8). Implant crowns (ICs) revealed significant median facial recession between IC10y and IC1y (0.17 mm). The facial bone wall dimensions were assessed by preoperative cone beam computed tomography and 2 subsequent scans taken at 6 and 10 y. The median facial bone wall thickness increased significantly from 0 mm at surgery to 1.67 mm at the 10-y examination. The facial vertical bone wall peak (DIC) was located at a median distance of 0.16 mm coronal to the implant shoulder. The facial vertical bone loss of DIC amounted to 0.02 mm between 6 and 10 y. Equivalence testing was performed for the null hypothesis of a difference of >0.2 mm per year between 2 respective time points, showing stable bone conditions. Modulating factors influencing the regenerative outcomes at 10 y were the preoperative proximal crest width and soft tissue thickness. In conclusion, the present study confirmed the long-term effectiveness of early implant placement with simultaneous contour augmentation through guided bone regeneration with a 2-layer composite graft in postextraction single-tooth sites offering stable bone conditions with low risks of mucosal recessions over an observation period of 10 y ( ClinicalTrials.gov NCT03252106).

Association Studies and Direct DNA Sequencing Implicate Genetic Susceptibility Loci in the Etiology of Nonsyndromic Orofacial Clefts in Sub-Saharan African Populations.

Orofacial clefts (OFCs) are congenital dysmorphologies of the human face and oral cavity, with a global incidence of 1 per 700 live births. These anomalies exhibit a multifactorial pattern of inheritance, with genetic and environmental factors both playing crucial roles. Many loci have been implicated in the etiology of nonsyndromic cleft lip with or without cleft palate (NSCL/P) in populations of Asian and European ancestries, through genome-wide association studies and candidate gene studies. However, few populations of African descent have been studied to date. Here, the authors show evidence of an association of some loci with NSCL/P and nonsyndromic cleft palate only (NSCPO) in cohorts from Africa (Ghana, Ethiopia, and Nigeria). The authors genotyped 48 single-nucleotide polymorphisms that were selected from previous genome-wide association studies and candidate gene studies. These markers were successfully genotyped on 701 NSCL/P and 163 NSCPO cases, 1,070 unaffected relatives, and 1,078 unrelated controls. The authors also directly sequenced 7 genes in 184 nonsyndromic OFC (NSOFC) cases and 96 controls from Ghana. Population-specific associations were observed in the case-control analyses of the subpopulations, with West African subpopulations (Ghana and Nigeria) showing a similar pattern of associations. In meta-analyses of the case-control cohort, PAX7 (rs742071, P = 5.10 × 10(-3)), 8q24 (rs987525, P = 1.22 × 10(-3)), and VAX1 (rs7078160, P = 0.04) were nominally associated with NSCL/P, and MSX1 (rs115200552, P = 0.01), TULP4 (rs651333, P = 0.04), CRISPLD2 (rs4783099, P = 0.02), and NOG1 (rs17760296, P = 0.04) were nominally associated with NSCPO. Moreover, 7 loci exhibited evidence of threshold overtransmission in NSOFC cases through the transmission disequilibrium test and through analyses of the family-based association for disease traits. Through DNA sequencing, the authors also identified 2 novel, rare, potentially pathogenic variants (p.Asn323Asp and p.Lys426IlefsTer6) in ARHGAP29 In conclusion, the authors have shown evidence for the association of many loci with NSCL/P and NSCPO. To the best of this knowledge, this study is the first to demonstrate any of these association signals in any African population.

EFFICACY AND SAFETY OF ORAL KETAMINE PREMEDICATION IN CHILDREN UNDERGOING DAY CASE SURGERY.

BACKGROUND: Oral premedication for paediatric age group is an uncommon practice amongst anaesthetists in Nigeria. Both parents and the child suffer some form of emotional or psychological distress. AIM: To determine the efficacy and safety of oral formulated ketamine for premedication in children scheduled for ambulatory surgeries. METHODS: Seventy three children aged 1 - 6 years with American Society of Anesthesiologists (ASA) physical status I-II were prospectively studied. They were assigned randomly to receive either 5 mg/kg (Group A), 10 mg/kg (Group B), or no ketamine (Group C).The children were observed for acceptance of premedication, sedation and anxiolysis at 10, 20 and 30 minutes after drug administration. Behavior/response of each child at the time of separation from parents, intravenous access, and acceptance of facemask for induction, postanaesthetic arousal state and complications were also recorded. RESULTS: There were 73 children in this study with a mean age of 37.4±18.0 months. The groups were comparable in age. The studied agent was tolerated by both groups that received premedication with no significant difference (P 0.73). Adequate sedation and anxiolysis were observed in groups A and B, (52%, 84%) and (68%, 88%) respectively. However, more children in group B (82.6%) had satisfactory behaviour at separation from parents and a better acceptance of anaesthetic face mask (64%) at induction than those in groups A and C (33.3%, 21.7%, respectively). No side effect was recorded in either of the premedication groups or the control group. CONCLUSION: Oral ketamine is acceptable and safe premedication for children. It provided good sedation, relieved anxiety and had no side effect in the children at the studied doses.

Extreme chromosomal instability forecasts improved outcome in ER-negative breast cancer: a prospective validation cohort study from the TACT trial.

BACKGROUND: Chromosomal instability (CIN) has been shown to be associated with drug resistance and poor clinical outcome in several cancer types. However, in oestrogen receptor (ER)-negative breast cancer we have previously demonstrated that extreme CIN is associated with improved clinical outcome, consistent with a negative impact of CIN on tumour fitness and growth. The aim of this current study was to validate this finding using previously defined CIN thresholds in a much larger prospective cohort from a randomised, controlled, clinical trial. PATIENTS AND METHODS: As a surrogate measurement of CIN, dual centromeric fluorescence in situ hybridisation was performed for both chromosomes 2 and 15 on 1173 tumours from the breast cancer TACT trial (CRUK01/001). Each tumour was scored manually and the mean percentage of cells deviating from the modal centromere number was used to define four CIN groups (MCD1-4), where tumours in the MCD4 group were defined as having extreme CIN. RESULTS: In a multivariate analysis of disease-free survival, with a median follow-up of 91 months, increasing CIN was associated with improved outcome in patients with ER-negative cancer (P trend = 0.03). A similar pattern was seen in ER-negative/HER2-negative cancers (Ptrend = 0.007). CONCLUSIONS: This prospective validation cohort study further substantiated the association between extreme CIN and improved outcome in ER-negative breast cancers. Identifying such patients with extreme CIN may help distinguish good from poor prognostic groups, and therefore support treatment and risk stratification in this aggressive breast cancer subtype.

A time series based sequence prediction algorithm to detect activities of daily living in smart home.

OBJECTIVES: The goal of smart homes is to create an intelligent environment adapting the inhabitants need and assisting the person who needs special care and safety in their daily life. This can be reached by collecting the ADL (activities of daily living) data and further analysis within existing computing elements. In this research, a very recent algorithm named sequence prediction via enhanced episode discovery (SPEED) is modified and in order to improve accuracy time component is included. METHODS: The modified SPEED or M-SPEED is a sequence prediction algorithm, which modified the previous SPEED algorithm by using time duration of appliance's ON-OFF states to decide the next state. M-SPEED discovered periodic episodes of inhabitant behavior, trained it with learned episodes, and made decisions based on the obtained knowledge. RESULTS: The results showed that M-SPEED achieves 96.8% prediction accuracy, which is better than other time prediction algorithms like PUBS, ALZ with temporal rules and the previous SPEED. CONCLUSIONS: Since human behavior shows natural temporal patterns, duration times can be used to predict future events more accurately. This inhabitant activity prediction system will certainly improve the smart homes by ensuring safety and better care for elderly and handicapped people.

Circumcision: perspective in a Nigerian teaching hospital.

BACKGROUND: The practice and pattern of male infants circumcised is influenced by culture, religion and socio-economic classification. The debate about the benefits and risks of circumcision has made a hospital-based practice the most acceptable. OBJECTIVE: The objective of this study is to evaluate the ages, indications, co-morbidity, types and methods of circumcision, usage and mode of anaesthesia and outcome of male circumcision at a tertiary health centre in Nigeria. MATERIALS AND METHODS: A retrospective review of male circumcision in a paediatric surgery unit was done from January 2002 to December 2007. The data was analysed using SPSS software version 15. RESULTS: There were 438 boys with age ranged between 6 days and 10 years (median 28 days, mean 53.6 days standard deviation 74.2). Neonatal circumcision (<29 days) was 201 (46%) and 318 (72.6%) of the children were circumcised by the 3 rd month of live. Religion or tradition were the major indicators in 384 (87.7%) patients while phimosis 38 (8.7%), paraphimosis 4 (1%), redundant post circumcision skin 10 (2.3%) and defective prepuce in 2 (0.5%) were other indications. Plastibel™ (PD) was used in 214 (48.9%), classical circumcision 194 (44.2%), guillotine technique (GT) and Gomco™ 10 (2.3%) cases each while 10 (2.3%) had a refashioning/re-excision post previous circumcision. There was an increase in use of PD, drop in the use of GT; and increase in the number of circumcision done over the years. Only 39.7% had anaesthesia administered and complication rate was 6.7%. CONCLUSION: Neonatal circumcision was highest in the hospital-based circumcision practice, which allowed the expected ideals in the use of devices in a tertiary health centre. However, the low rate of anaesthetic use is unacceptable.

Congenital giant hydroureteric cistern in a duplex system of an infant.

Duplex collecting system is a congenital genitourinary anomaly commonly found incidentally. Our experience with a duplex system associated with giant hydroureter presenting as mobile abdominal swelling that was noticed from birth, constipation, and failure to thrive is described. Ultrasound and IVU did not assist in making the diagnosis, while a barium enema suggested a colonic duplication. Congenital giant hydroureter should be considered as a differential diagnosis in infants with cystic abdominal swelling. A preserved renal moiety attributed to a dilated ureteric cistern was a unique theory in this case.

Amelogenesis imperfecta: a diagnostic and pathological review with case illustration.

Amelogenesis mperfecta is an inherited disorder of enamel development, which results n morphological defects of both the primary and secondary dentition, usually in the absence of systemic involvement. Mutational defects involving the genes that encode for enamel matrix proteins and proteinases are mplicated in this disorder. The phenotypic expression is variable, spanning a spectrum from barely discernible changes to severe aesthetic and functional enamel defects. The specific type and location of the genetic mutation, as well as the mode of inheritance, determine the clinical presentation Clinical recognition and early therapeutic intervention are required for the most successful outcome. An essentia component of the treatment process includes patient counselling and education. Patient management requires a dedicated multi-disciplinary approach. The disorder is reviewed here with emphasis on the clinical significance for the oral healthcare worker. In addition, a case is presented in order to provide an example of treatment panning and dental management.

Outcome of management of complicated extragonadal teratoma in a resource poor setting.

BACKGROUND: Extragonadal teratomas (EXGTs) are ubiquitous in the human body; hence, they have varied presentation. In underdeveloped areas presentation and management are affected by socio-economic, cultural and health facilities factors. The aim of this study was to review the outcome of management of complicated EXGT in a tertiary health centre. MATERIALS AND METHODS: A review data of paediatric patients with EXGT was done between January 1999 and December 2012. Variables reviewed were bio-data, mode of presentation and site of tumour, comorbidity, treatments and outcome. The data was analysed with Statistical Package for Social Sciences (SPSS (R)) version 16.0. RESULTS: There were 21 complicated EXGT (77.8%) among 27 children, age ranges from 4 days to 16 years (median = 2 years). Male:Female ratio of 1:2. The complications per region of the body at presentation were cervical 4 (66.7%), mediastinal 2 (100%), abdominal 3 (75%) and sacrococcygeal 12 (75%). The complications were respiratory distress 6, intestinal obstruction 5, faecal incontinence 2, bladder outlet obstruction 3, malignant transformation 5, ruptured sacrococcygeal teratoma 2, ulcerated tumour 2, anaemia 3 and malnutrition 3. There were 5 (23.8%) progressive disease post-excision outside our facility. Excision biopsy was successful in 19 (85%) patients two of which had neoadjuvant cytotoxic therapy. Overall mortality was 5 (23.8%) (septicaemia, anaemia, respiratory distress, renal failure) and post-excision mortality was 11.8% (endotracheal tube blockage and progressive disease). CONCLUSION: Delay presentation (due to local belief, ignorance and poverty) malnutrition, sepsis, malignant transformation characterised presentation of children in this study and the lack of paediatric intensive care unit facility and intensivists compromised survival of children with EXGT.

Prevalence of snoring and symptoms of sleep disordered breathing among primary school pupils in Ilorin, Nigeria.

BACKGROUND/AIM: Snoring is the production of sound from the upper aero-digestive tract during sleep due to turbulent airflow This study is to determine the prevalence, pattern, night and daytime symptoms of snoring among nursery and primary school pupils in Ilorin, Nigeria due to its public health importance. MATERIALS AND METHODS: This cross sectional survey was carried out among nursery /primary school pupils in Ilorin, Kwara state between April and September, 2010. Ten schools were selected randomly from 100 schools sited within the 3LGAs of Ilorin municipality. Also private and public schools with different parental social economic status were selected. The pupils were selected from nursery 2 to primary 6 in each school using the class registers with the aid of a table of random numbers with 1500 children assessed. The parents/guardians were made to fill the questionnaires and same returned with visitations to the schools twice weekly and reminders sent via phone calls. Data were analyzed using EPIINFO 2002 version 2 software. RESULTS: 1500 questionnaires were given out but 909 were completely filled and returned (response rate of 61%.). There were 598(65.8%) non snorers (NSn) and 311(34.2%) snorers (Sn) at different scales with 153 male snorers to 158 female snorers. The ages of the children ranges from 3 to 16 years (mean ± SD, 8.3 ± 4.8 years. The mean age for the Sn was 8.2 and 8.3 for NSn (range 3-6 years). No statistical difference in age, gender or socio-economic status between Sn and NSn. 598(65.8%) were non snorers (NSn) and 311(34.2%) were snorers (Sn) especially in the age groups 3-6 years, 121(38.9%) and above 6 years of age 101(32.7%) and below 3 years were 89(28%). CONCLUSION: Snoring is an important health problem among the pupils as a significant percentage snores and most of them are between third and sixth year of life.

ISSR and RAPD based evaluation of genetic stability of encapsulated micro shoots of Glycyrrhiza glabra following 6 months of storage.

In vitro grown axillary micro shoots of Glycyrrhiza glabra were encapsulated in alginate beads. Following 6 months of normal storage at 25 ± 2°C the re growth of encapsulated G. glabra micro shoots, reached 98% within 30 days of incubation on MS medium supplemented with 0.1 mg/l IAA. Re growth was characterized by the development of both shoot and root from single encapsulated micro shoot. Healthy plants were established to glass house with 95% survival. The genetic fidelity of plants obtained after conversion of alginate beads was ascertained through 10 RAPD and 13 ISSR primers. Of the 10 RAPD primers tested, 6 of them produced 14 clear and reproducible amplicons with an average of 2.3 bands per primer out of which 28.57% were polymorphic generated by only two primers. Eight ISSR primers produced total 37 bands ranging between 300 and 3,500 bp length. Number of scorable bands for each primer varied from 3 to 8 with an average of 4.6 bands per primer. Cluster analysis from ISSR and RAPD showed that all the tested plants including the mother plant distributed in two major groups with similarity coefficient ranging from 0.91 to 0.96 for RAPD and 0.89 to 0.97 for ISSR.
