Abstract: Background/Objectives: Performance of the vaccination programme in Nigeria is lower than the regional average as well the 95% target necessary for sustained control of vaccine preventable diseases. This study is aimed at assessing the vaccination coverage and its associated factors in children aged 11 - 23 months in Enugu Metropolis. Methods: A cross sectional study in which caregivers and their children pair, aged 11 - 23 months attending children’s outpatient clinics in Enugu metropolis was undertaken. Respondents were selected consecutively while data were collected using pretested interviewer administered semi-structured questionnaire. Data were analyzed using SPSS version 20.0 while level of significance was set at p < 0.05. Logistic regression analysis was used to identify independent predictors of full vaccination. Results: Of 351 subjects studied, 84.9% (298) were fully immunized according to the national programme on immunization schedule using both vaccination cards and history. The OPV0, OPV3, pentavalent-1, pentavalent-3 and measles coverage at the time of survey were 100.0%, 97.2%, 98.0%, 98.6%, 96.9% and 95.4%, respectively. On logistic regression: maternal occupation (government employees), children born in government hospitals and knowledge of when to start and complete vaccinations in a child were the likely predictors for completion of full vaccination in the children. Conclusion: The vaccination coverage among the study group was adjudged to be relatively high. Delivery of a child in a government hospital and the knowledge of the age when routine vaccinations should begin and end in a child were the independent predictors of the high vaccination coverage rate observed. Awareness and health education efforts in government tertiary hospitals should be extended to private and other hospitals to improve and sustain national vaccination coverage in Nigeria.

Abstract: This study was aimed at using the infrared tympanic thermometer (IRTT) in oral mode to measure temperature in febrile and afebrile children less than 5 years.Rectal and tympanic temperatures were measured consecutively in 400 febrile and 400 afebrile under-5 children matched for age, using the mercury-in-glass thermometer and the IRTT in oral mode respectively.In the febrile children, the mean tympanic temperature was 38.6 ± 0.9°C, while the mean rectal temperature was 39.0 ± 0.8°C. In the afebrile group, the mean tympanic temperature was 37.0 ± 0.4°C, while the mean rectal temperature was 37.4 ± 0.3°C. The mean difference between rectal and tympanic temperatures in both groups was statistically significant. There was good correlation between the two temperatures. The tympanic thermometer used in the oral mode had a sensitivity of 87.3% and a specificity of 96.5%.The IRTT (oral mode) may not be reliable in estimating 'core' body temperature in children under the age of five years, but with a fairly good sensitivity and specificity, as well as its other advantages such as short duration of measurement, convenience and safety, it is a useful instrument for screening children with fever in a busy setup.The best site to measure 'core' temperature is the temperature regulating centre situated in the hypothalamus, but since this is not feasible, body sites that most closely approximate the 'core' temperature provide the most accurate readings [1]. The pulmonary artery, oesophagus, trachea, nasopharynx and bladder have all been used in anaesthetized patients [2]. However, access to these sites require invasive procedures and are not feasible for routine clinical use, hence the use of rectal temperature as the 'gold standard' in most clinical settings [3,4]. Apart from the rectum, the oral cavity and axilla have traditionally been used to take temperature in children, using mercury- in -glass thermometer. In recent years, however, the use of mercury thermometers has been di

Abstract:
Background: Assessment of the safety profile of the new rotavirus vaccines in Africa requires base-line epidemiological data on intussusception. Hence, this study was aimed at describing the prevalence and associated factors of intussusception in under-five children in Enugu, Southeast, Nigeria. Methods: This was a retrospective descriptive study involving the sixty reported cases of intussusception in under-five children admitted in a hospital in Enugu between 2007 and 2012. Cases of intussusception were selected using the Brighton collaboration intussusception working group level I diagnostic criteria. Information sought from the patients’ folders included demographic characteristics and clinical manifestations including history of previous rotavirus vaccination, duration of illness prior to presentation, diarrhoea, vomiting, passage of red currant jelly-like stool, abdominal mass and distension, method of diagnosis, treatment option(s) employed and their outcomes. The data was analyzed using SPSS version 17.0. Results: The majority of the cases were aged less than one year (53; 88.3%) while the average incidence of intussusception was 0.1 per 1000. None of the cases had received rotavirus vaccinations. The common clinical presentations were vomiting, 55 (17.2%), passage of red currant stool 50 (15.6%), fever 50 (15.6%) and abnormal/absent bowel sound 43 (15.9%). Diagnosis was essentially with the aid of abdominal ultrasonography, 38 (63.3%) while surgery (laparotomy) was the treatment of choice in most cases 48 (80.0%). The case fatality rate was 3 (5.0%). Conclusion: None of the cases studied could be directly linked to rotavirus vaccinations. But seasonal peak incidence coincided with rotavirus diarrhea peak incidence. Efforts should be made to institute post-rotavirus vaccine licensure prospective surveillance study in order to fully determine any relationship between rotavirus vaccination and intussusception in Enugu, South east, Nigeria.

Psychosocial issues in palliative care: A review of five cases
Onyeka Tonia
Indian Journal of Palliative Care , 2010,
Abstract: Palliative care is not just vital in controlling symptoms of the patient′s disease condition, but also aims to extend the patient′s life, giving it a better quality. However, several times in the course of management, the psychosocial impact of cancer, HIV/AIDS, and other life-limiting disease conditions may not be noticed and dealt with during the admission period, thereby giving rise to a more complex situation than the disease condition itself. This article aims to review some psychosocial issues and measures that can be taken to address them. It highlights the various roles and the importance of the clinician, nurse, social worker, and other members of the multidisciplinary team in tackling these issues and will help healthcare professionals in this field achieve better practice in the future.
Masseter muscle rigidity: Atypical malignant hyperthermia presentation or isolated event?
Onyeka Tonia
Saudi Journal of Anaesthesia , 2010,
Abstract: This report describes a case of masseter muscle rigidity encountered at the start of an elective gynaecological procedure. At preoperative assessment, the patient, a 41-year old woman with a previous non-eventful surgical and anesthetic history was given a Mallampati score of 3. Following suxamethonium administration, full mouth opening proved difficult. Laryngoscopy and tracheal intubation were not possible leading to the eventual use of a laryngeal mask airway and resulting in a successful anaesthetic outcome. A number of possibilities that may account for this situation as well as viable options for airway access in such cases are discussed below.
Choice of Future Career amongst Medical Students in Enugu, Nigeria: Implications for Anaesthesia
TC Onyeka, NP Ewuzie
Nigerian Journal of Surgery , 2010,
Abstract: Background Despite its central role in modern healthcare delivery, anaesthesia has failed to attract adequate medical manpower in most developing countries. As a result, majority of anaesthetics are performed by non-physician practitioners. Objectives In this study, we examined the factors influencing choice of future career by medical student inEnugu, Nigeria and the implications for anaesthesia. Methods We distributed questionnaires to medical students in the last two years of their training at the University of Nigeria, Enugu, asking them to indicate in order of priorities three specialties they will most likely consider for future career. They were also requested to state fourmost important factors influencing their choice. Results All 195 completed forms were returned; 64%were males and the average age of the respondents was 25.1 years. One hundred and eighty students (93%) agreed to specialise, 1 did not while 12 were undecided. Only 1% of the students chose anaesthesia as their first choice. The other specialties like surgery (29%), paediatrics (14%), public health (14%), obstetrics and gynaecology (12%), radiology (11%), internal medicine (5%) and ophthalmology (5%) were considerably of more interest to them. Ability to pursue other hobbies (40%), academic and research opportunities (23%), availability of training post (10%), career progression (10%), earning potential (9%) and influence of a role model (6%) were the factors affecting career decisions among the students. Conclusion This study has highlighted a very low level of interest for anaesthesia amongst Nigerian undergraduates. It also showed that ability to pursue other hobbies, availability of posts as well as academic and research opportunities are the main influencing factors in the choice of future specialty.We call for urgent measures be put in place tomake anaesthesiamore attractive to youngmedical graduates.

A. C. Onyeka, V. U. Nlebedim, C. H. Izunobi
Open Journal of Statistics (OJS) , 2014, DOI: 10.4236/ojs.2014.44029
Abstract:

This paper is an extension and generalization of the study carried out by [1] on the estimation of the population ratio (R) of the population means of two variables (y and x) under Simple Random Sampling (SRS) scheme, using a variable transformation of the auxiliary variable, x. All the six estimators proposed by [1] are easily identified as special cases of the proposed class of estimators. Asymptotic properties of the proposed class of estimators are derived theoretically and subsequently verified using empirical illustrations. Some of the proposed estimators are found to have relatively large gains in efficiency over the customary ratio estimator, \"\"\"\"\"\" for the given data set.

Abstract: Extending the work carried out by [1], this paper proposes six combined-type estimators of population ratio of two variables in post-stratified sampling scheme, using variable transformation. Properties of the proposed estimators were obtained up to first order approximations,(on1), both for achieved sample configurations (conditional argument) and over repeated samples of fixed size n (unconditional argument). Efficiency conditions were obtained. Under these conditions the proposed combined-type estimators would perform better than the associated customary combined-type estimator. Furthermore, optimum estimators among the proposed combined-type estimators were obtained both under the conditional and unconditional arguments. An empirical work confirmed the theoretical results.

Open Journal of Statistics (OJS) , 2015, DOI: 10.4236/ojs.2015.51004
Abstract: The study proposes, along the line of [1], six separate-type estimators for estimating the population ratio of two variables in post-stratified sampling, using variable transformation. Properties of the proposed estimators were obtained up to first order approximations, both for achieved sample configurations (conditional argument) and over repeated samples of fixed size n (unconditional argument). Efficiency conditions, under which the proposed separate-type estimators would perform better than the associated customary separate-type estimators in terms of having smaller mean squared errors, were obtained. Furthermore, conditions under which some of the proposed separate-type estimators would perform better than other proposed separate-type estimators were also obtained. The optimum estimators among the proposed separate-type estimators were obtained and an empirical illustration confirmed the theoretical results.
