A prospective study of 40 children with epilepsy was carried out between June 1990 and August 1991 at Port Moresby General Hospital. Half of the children had yet to start school. Significant features in their past medical histories were acute meningitis (38%), tuberculous meningitis (10%), febrile convulsions (10%) and head trauma (5%). Most cases had grand mal epilepsy (80%). The majority of the children with epilepsy (90%) were treated with a single drug, which was usually phenobarbitone. 22% had received more than one drug, but not simultaneously. Significant side-effects requiring change of treatment occurred in 10%. Disturbed behaviour was reported in 55% and 22% had a poor social outcome. 45% had complete control of fits clinically. This study showed that in Port Moresby acute meningitis is a significant cause of epilepsy in young children, the majority of whom present with grand mal epilepsy, which is usually controlled by phenobarbitone, a readily available and cheap drug and still a useful anticonvulsant in the developing world.

To determine the health care needs and practices of the area covered by the Koje-Do Community Health and Development Project, a questionnaire survey was conducted by trained public health nurses to 971 randomly selected members of 160 families from the 8 villages of the area. The self-reported illness prevalence rate, the self-reported diagnosis of illness, treatment, sources of treatment and reasons for failure to obtain treatment were discussed by the epidemiological, socioeconomical factors such as age, sex, occupation, education and family size. Some significant findings are: 1. The parents of girls less than 6 years old reported only about half of the rate illness (32%) that the parents of boys the same age reported (56%). About twice as many women (7.4%) reported vague symptoms as men (3.2%). 2. The age group 0-5 years old had an illness prevalence of 44%, those 6-34 years old reported 28% ill and those 35 years old and older reported 49% ill during the preceeding months. The most striking effect of age upon the diagnosis reported in the high rate of respiratory and ENT illnesses in 0-5year old age group. Age significantly reduced the rates of treatment for those incapacitate by their illnesses in the 6-10 and 50-plus year old age groups. 3. If the head of household was literate the family members are more likely to receive treatment, and less likely to use herb doctors. 4. Occupation and age adjusted family size did not affect significantly the illness prevalence, diagnosis of the illness and treatment. 5. Thirty-six percent (36%) of the subjects reported an illness during the preceeding month and 12% of them were incapacitated by the illness. 6. Fifty-eight percent (58%) of those ill and 73% incapacitated by illness received treatment. 7. Fourty-four percent (44%) of the treatment was obtained from local drug outlets, 21% from the mainland, 15% from local physician and 10% from herb doctors. 8. Fourty-eight percent (48%) of those failing to receive treatment did so because the illness was not serious enough, 46% because treatment was too expensive, 3% because treatment was not effective, 1% because treatment was not easily available and 2% for other reason.

Purpose: Preoperative identification of the intraosseous posterior superior alveolar artery (PSAA) is critical when planning sinus surgery. This study was conducted to determine the distance between the cementoenamel junction and the PSAA, as well as to identify factors influencing the detection of the PSAA on cone-beam computed tomography (CBCT). Materials and Methods: In total, 254 CBCT scans of maxillary sinuses, acquired with 2 different scanners, were examined to identify the PSAA. The distance from the cementoenamel junction (CEJ) to the PSAA was recorded at each maxillary posterior tooth position. Binomial logistic regression and multiple linear regression were employed to evaluate the effects of scanner type, CBCT parameters, sex, and age on PSAA detection and CEJ-PSAA distance, respectively. P-values less than 0.05 were considered to indicate statistical significance. Results: The mean CEJ-PSAA distances at the second molar, first molar, second premolar, and first premolar positions were 17.0±4.0 mm, 21.8±4.1 mm, 19.5±4.7 mm, and 19.9±4.9 mm for scanner 1, respectively, and 17.3±3.5 mm, 16.9±4.3 mm, 18.5±4.1 mm, and 18.4±4.3 mm for scanner 2. No independent variable significantly influenced PSAA detection. However, tooth position (b = - 0.67, P<0.05) and scanner type (b = - 1.3, P<0.05) were significant predictors of CEJ-PSAA distance. Conclusion CBCT-based estimates of CEJ-PSAA distance were comparable to those obtained in previous studies involving cadavers, CT, and CBCT. The type of CBCT scanner may slightly influence this measurement. No independent variable significantly impacted PSAA detection.

OBJECTIVES: Recently, bioceramic sealers like EndoSequence BC Sealer (BC Sealer) have been introduced and are being used in endodontic practice. However, this sealer has limited research related to its retreatability. Hence, the aim of this study was to evaluate the retreatability of two sealers, BC Sealer as compared with AH Plus using micro-computed tomographic (micro-CT) analysis. MATERIALS AND METHODS: Fifty-six extracted human maxillary incisors were instrumented and randomly divided into 4 groups of 14 teeth: 1A, gutta-percha, AH Plus retreated with chloroform; 1B, gutta-percha, AH Plus retreated without chloroform; 2A, gutta-percha, EndoSequence BC Sealer retreated with chloroform; 2B, gutta-percha, EndoSequence BC Sealer retreated without chloroform. Micro-CT scans were taken before and after obturation and retreatment and analyzed for the volume of residual material. The specimens were longitudinally sectioned and digitized images were taken with the dental operating microscope. Data was analyzed using an ANOVA and a post-hoc Tukey test. Fisher exact tests were performed to analyze the ability to regain patency. RESULTS: There was significantly less residual root canal filling material in the AH Plus groups retreated with chloroform as compared to the others. The BC Sealer samples retreated with chloroform had better results than those retreated without chloroform. Furthermore, patency could be re-established in only 14% of teeth in the BC Sealer without chloroform group. CONCLUSION: The results of this study demonstrate that the BC Sealer group had significantly more residual filling material than the AH Plus group regardless of whether or not both sealers were retreated with chloroform.

OBJECTIVETo develop the reproducible in vitro propagation protocols for the medicinally important plants viz., Achyranthes aspera (A. aspera) L. and Achyranthes bidentata (A. bidentata) Blume using nodal segments as explants.

METHODSYoung shoots of A. aspera and A. bidentata were harvested and washed with running tap water and treated with 0.1% bavistin and rinsed twice with distilled water. Then the explants were surface sterilized with 0.1% (w/v) HgCl2 solutions for 1 min. After rinsing with sterile distilled water for 3-4 times, nodal segments were cut into smaller segments (1 cm) and used as the explants. The explants were placed horizontally as well as vertically on solid basal Murashige and Skoog (MS) medium supplemented with 3% sucrose, 0.6% (w/v) agar (Hi-Media, Mumbai) and different concentration and combination of 6-benzyl amino purine (BAP), kinetin (Kin), naphthalene acetic acid (NAA) and indole acetic acid (IAA) for direct regeneration.

RESULTSAdventitious proliferation was obtained from A. aspera and A. bidentata nodal segments inoculated on MS basal medium with 3% sucrose and augmented with BAP and Kin with varied frequency. MS medium augmented with 3.0 mg/L of BAP showed the highest percentage (93.60±0.71) of shootlets formation for A. aspera and (94.70±0.53) percentages for A. bidentata. Maximum number of shoots/explants (10.60±0.36) for A. aspera and (9.50±0.56) for A. bidentata was observed in MS medium fortified with 5.0 mg/L of BAP. For A. aspera, maximum mean length (5.50±0.34) of shootlets was obtained in MS medium augmented with 3.0 mg/L of Kin and for A. bidentata (5.40±0.61) was observed in the very same concentration. The highest percentage, maximum number of rootlets/shootlet and mean length of rootlets were observed in 1/2 MS medium supplemented with 1.0 mg/L of IBA. Seventy percentages of plants were successfully established in polycups. Sixty eight percentages of plants were well established in the green house condition. Sixty five percentages of plants were established in the field.

CONCLUSIONSThe results have shown that use of nodal buds is an alternative reproducible and dependable method for clonal propagation of A. aspera and A. bidentata. The high rate of direct shoot-root multiplication and their high rate of post-hardening survival indicate that this protocol can be easily adopted for commercial large scale cultivation.

OBJECTIVE: to map a mouse deafness gene, identify the underlying mutation and develop a mouse model for human deafness. METHODS: genetic linkage cross and genome scan were used to map a novel mutation named hypoplasia of the membranous labyrinth (hml), which causes hearing loss in mutant mice. RESULTS: 1. hml was mapped on mouse Chr 10 (~43 cM from the centromere) suggests that the homologous human gene is on 12q22-q24, which was defined on the basis of known mouse-human homologies (OMIM, 2004). 2. This study has generated 25 polymorphic microsatellite markers, placed 3 known human genes in the correct order in a high-resolution mouse map and narrowed the hml candidate gene region to a 500kb area.

Purpose: Visual impairment from retinal re-detachment could be debilitating. The aim of this review is to evaluate the role of 360° laser retinopexy on success rate of rhegmatogenous retinal detachment (RRD) repair by a meta-analysis study. Methods: The PubMed, Scopus, and the Cochrane Library databases were searched comprehensively from the date of database inception to January 2021, evaluating the role of 360° laser retinopexy in visual and anatomical success rate of RRD repair. This review was conducted based on the preferred reporting items for systematic review and meta-analysis (PRISMA) protocols. Results: Among 202 articles screened for eligibility, six studies were found to be eligible for inclusion in our final analysis. Our meta-analysis demonstrates that prophylactic treatment with circumferential laser photocoagulation has no significant effect on the initial rate of retinal re-detachment or final best-corrected visual acuity following pars plana vitrectomy repair of RRD. Subgroup analysis of studies (n = 3) with 23-gauge pars plana vitrectomy, however, favors attachment rate in patients undergoing 360° prophylactic laser treatment. Conclusions Three hundred and sixty degree laser retinopexy appears to have favorable outcomes in patients undergoing 23-gauge retinal detachment repair. This protective effect, however, is not apparent with inclusion of 20-gauge vitrectomy studies.

Background: Low self-esteem can be an issue among health-care workers due to the hierarchical medical system. Health-care workers are also in a high pressure environment that can lead to stress and burnout. This study was conducted to estimate the proportion of health-care workers with low self-esteem, high stress, and burnout and the factors associated with these in a private hospital in Bangalore city. Methods: This cross-sectional study included a random sample of health-care workers of various cadres – doctors, nurses, nursing aides, technicians, and workers in ancillary departments such as laundry, dietary, central sterile supply department, and pharmacy, with probability proportional to size. Rosenberg Scale for Self-esteem, Cohen's Perceived Stress Scale, and Shirom–Melamed Burnout Measure were used as study tools. Results: Among the 306 health-care workers, there were high levels of low self-esteem (48.4%), stress (38.6%), and burnout (48.7%), with the lowest levels being among doctors. Those aged younger than 30 years had significantly lower self-esteem and greater stress. Conclusions Health-care workers with low self-esteem were nearly thrice more likely to suffer high stress, Odds Ratio (OR) = 2.84 (1.36–5.92), and those who were stressed had more than three times higher chance of experiencing burnout, OR = 3.6 (2.02–6.55). Path analysis showed that low self-esteem among health-care workers had a direct effect on burnout, as well as an indirect effect through stress (mediator variable). This study indicates the need for screening and counseling for low self-esteem, stress, and burnout as part of a periodic medical examination of all cadres of health workers.
