This work presents the results of the comparison of two pheromone traps for the capture of the red palm weevil. Trap A was a yellow funnel trap with green top, while trap B was a yellow pitfall trap, both equipped with pheromone. The experiment took place at Sissi and Milatos villages of Lasithi prefecture, mid-North coastline of Crete, from March 2009 to February 2010. The total number of traps deployed at each sampling varied between 24 and 36 due to various disturbances (trap loss, dirt in traps etc.). In each location, always both trap types were present. A total of 3139 adults of red palm weevil were captured during the trials. Temporal variability shows similar pattern for both trap types, as well as for both sexes. Type A traps captured 1376 insects with a ratio of 1♂ to 3.40♀, while type “B” captured 1763 insects with a ratio of 1♂ to 3.15♀. ANOVA revealed significant differences between the two traps in the number of catches (Trap A: 38.22 insects per fortnight /trap, Traps B: 48.97 insects per fortnight /trap). Comparing females and males of both trap types as separate groups, the statistical significance is more profound. At Sissi on average 1.61 males and 5.32 females were captured per fortnight/trap, with an average male to female ratio of 1:3.30, being 1♂: 3.85♀ for type A traps and 1♂: 2.94♀ for type B traps. At Milatos 1.33 males and 4.04 females per trap were recorded and the male to female ratio was 1:3.04, this ratio being 1♂:2.36♀ and 1♂:3.86♀ for type A and B traps respectively. Impressively high captures (more than 150 up to almost 250 in traps of B type and from almost 150 up to more than 350 in traps of A type) were observed from September 2009 to January 2010 with a peak of 356 and 240 on January the 15th for both A and B type traps.

Introduction: The burden of haematological malignancies in developing countries is on the rise. This burden may be further aggravated in Bhutan due to the aging population and rapid modernization of the nation. Despite this, there is a paucity of information about the incidence and pattern of leukemia in the Bhutanese population. In this retrospective study, we aim to investigate the incidence and pattern of leukemia in Bhutan using a database of leukemia diagnosed at Jigme Dorji Wangchuck National Referral Hospital, Thimphu, Bhutan from January 2008 to December 2015. Methods: The diagnoses and classification of leukemias were based on the morphology of blood cells on peripheral blood and bone marrow smears. The data was analyzed with descriptive statistics. The age-standardized incidence rate per 100,000 populations and its 95% confidence interval was calculated to assess the statistical significance. Results: In total 118 patients were diagnosed with leukemia over the period of eight years. Leukemia was found to be more frequent in male (51.69%) compared to female (48.30%) with a male to female ratio of 1.1:1. Acute leukemia accounted for 66.95% of all leukemia case diagnosed, whereas chronic leukemia accounted for only 33.05% of the cases. The average, annual, age-standardized incidence rate of leukemia per 100,000 population was 2.30 (95% CI: 1.87-2.73). Conclusions: The incidence and pattern of leukemia in the Bhutanese population is similar to other published literature. Leukemia is not uncommon in the Bhutanese population, thus additional studies on risk factors for leukemia in the Bhutanese population is necessary.

Background: Refractive error is one of the eye disorders with the capability of causing visual impairment. We needed to know the various types and proportion of refractive errors seen in patients attending an eye clinic at the tertiary health centre.Aim: An observational study was carried out to determine the profile of refractive error in a southwestern Nigeria hospital.Methods: All new cases with the diagnosis of refractive error between January 2015 and December 2016 had autorefraction and subjective refraction to determine the types and values of refractive error. Data were analysed with SPSS 20. Statistical significance was inferred at p < 0.05.Results: Refractive error constituted 618 (21.4%) of the total new cases. The mean age was 39.3 ± 22.96 years. The male to female ratio was 1:1.8. Children constituted 25.7% of all the cases. The most common refractive error was myopia in 64.3%. A total of 312 (50.5%) patients had other co-existing ocular disorders with allergic conjunctivitis on the top of the list. The number of visually impaired reduced to 70 (5.64%) after the correction of existing refractive error with about 94.1% having their visual acuity restored to normal.Conclusion: Refractive error was a common eye disorder among our patients with the proportion of children about a quarter of all patients. We recommend that childhood refractive errors should be given prioritised attention in eye outreach programmes.

Introduction: Neonatal tetanus is a highly debilitating disease with high mortality. Global efforts at eliminating the disease in developing countries are yielding results but slower than expected. The high case fatality of neonatal tetanus remains a therapeutic challenge to physicians and requires continuous evaluation. This study aimed to determine the incidence and outcome of neonatal tetanus in Zaria, northwestern Nigeria. Methodology: A retrospective study of neonatal tetanus was conducted at the Neonatal Unit of Ahmadu Bello University Teaching Hospital, Zaria, between January 2005 and December 2009. Data generated were analyzed using the Epi Info version 3.5.1 software and statistical significance was set at p < 0.05. Results: Of the 2,692 newborns admitted during the study period, 20 had tetanus, giving an overall prevalence of 0.7%. There were 14 males and 6 females (male to female ratio 2.3:1). The mean age and weight at presentation were 8.3 ± 4.0 days and 2.7 ± 0.3 kg, respectively. The mean incubation period was 3.2 ± 2.0 days. Four infants (20.0%) survived, one was discharged against medical advice and 15 (75.0%) died. Factors associated with mortality were presentation at less than seven days of life, low Hendrickse score at presentation (p = 0.0005) and hypoglycaemia (p = 0.0374). Conclusion: The incidence and the mortality rate of neonatal tetanus appear to be lower than those previously reported by our centre for the same region. Therefore, the ongoing global efforts for disease elimination and further improvements in the quality of care should be sustained.

Abstract Purpose The aim of this study was to conduct epidemiologic investigations on the pattern of the lesion and differences between treatment modalities in terms of recurrence by reviewing follow-up records to form a basis for planning patient follow-up visits. Materials and methods In this retrospective, single-center cohort study, 266 patients diagnosed with odontogenic keratocyst between 1993 and 2013 were included. Medical records and radiographic images were analyzed for age distribution, occurrence site and size, treatment modalities, and recurrence. Results The average age at first diagnosis was 33.1 years, and the male to female ratio was 1.33:1.00. The highest rate of incidence was in the third decade followed by the fourth, second, and fifth decades. The incidence in the maxilla was 34%, and 66% in the mandible. Mandibular ramus was most commonly involved. Lesions between 3 and 6 crowns were the most common, and the rate of recurrence increased with size. Enucleation after decompression had higher rate of recurrence (35.8%) than enucleation (27.1%), but there was no statistical significance. Conclusion The recurrence of odontogenic kerotocyst (OKC) was significantly associated with large size, multilocular form, and surgical procedure. A 10-year follow-up period is recommended to determine any recurrence of OKC.

Introduction: This study was designed to determine the epidemiological profile of hip fractures among Greek population with special importance to the cause of fracture, their characteristics, the treatment instituted and to assess the incidence.   Methods: The current study conducted in a single hospital in the northern part of Greece, in the regional unit of Grevena, during the 2016 calendar year. Patients themselves, or a relative member or a caregiver, were interviewed by a questionnaire regarding to the past medical history, time and place of the fracture occurrences.   Results: The 73 patients included in the study presented a mean age of 83.5 years, with a male-to-female ratio of 1:2.17. Falling from the same level was the cause of 97.6% of the fractures. Transtrochanteric fractures accounted for 52.1% of the fractures, femoral neck fractures, 38.4% and subtrochanteric fractures, 9.6%. More fractures are seen during the summer months (32.9%), inside the house (61.6%) and during the morning (49.3%). The overall annual incidence rate was 672.2 per 100,000 inhabitants (442.6 and 882.9 per 100,000 male and female, respectively). Length of waiting time to surgery was 1.87 days and length of hospital stay was 8.46 days, without statistical significance according to the type of surgery, the age group and the associated comorbidities. Hypertension (87.7%) was the most common comorbidity, followed by heart disease (50.7%) and depression (31.5%).   Conclusion: The patients attended at this hospital presented an epidemiological profile similar to the worldwide literature. Hip fracture rates in the region of Grevena are higher than other regions in Greece, such as Athens and Crete.
