Walking track analysis: an assessment method for functional recovery after sciatic nerve injury in the rat
Walking track analysis was first described by de Medinaceli et al. This technique
has been significantly modified to provide methods of indexing nerve
function that are more valid. Moreover, it has been questioned by several authors.
The aim of the present review is to offer a combined knowledge about
walking track analysis for scientists who deal with neuroscience
Awareness and Practice of Contraception among Female Secondary School Students in Uyo, Nigeria
Adolescent sexual activity is very prevalent in many countries. Unprotected premature sexual intercourse results in a high incidence of induced abortion, unwanted pregnancy and
sexually transmitted infections.
Objective: The aim of this study was to determine the degree of awareness of contraception and its practice among female secondary school students in Itu, Akwa-Ibom State, Nigeria.
Method: A descriptive cross sectional study design was used to recruit 378 consenting female students selected by simple random sampling. Semi-structured, self-administered
questionnaires were administered after explanation of the study and assurance of confidentiality. Three hundred and twelve forms were properly filled and analysis was done manually on these using simple proportions and percentages.
Results: Majority of the respondents were Ibibio 220 (70.5%) and between 13 and 17 yrs old (89.6%). Two hundred and thirty six
(75.6%) were aware of contraception. Twenty nine (16.0%) of those who were sexually active had ever practice any form of
contraception. The three common forms of contraception known were the male condom (36.0%), the calendar method (34.0%) and the oral contraceptive pills (25%). The foremost sources of information about contraception were from TV/radio (36.0%), parents (25.0%) and female friends (14.8%). Of those who were sexually active 116(64.8%) had sexual debut at 11-15years of age. Conclusion: This study demonstrated that the
level of awareness of contraception was high but the practice of contraception was comparatively low. It also demonstrated that
the age at sexual debut was early and the rate of sexual intercourse high. This emphasizes the need for provision of timely and accurate contraceptive information through sex
education in secondary schools in our environment.

The prevalence of syphilis in pregnant women in Akwa Ibom State, Southern Nigeria
Background: Treponema pallidum, the causative organism of syphilis has been a public health challenge for centuries. Syphilis is a significant cause of morbidities and mortalities in pregnant women, and information regarding its prevalence in Nigerian pregnant women is scanty particularly from the south‑south zone.
Objective: To determine the prevalence of syphilis in women receiving antenatal care in twelve health care centres in Akwa Ibom State, Nigeria.
Methodology: Pre‑coded structured questionnaires were administered to 911 participants over an eight week period. Venous blood samples were collected from each participant and tested with a Treponema pallidum immunochromatographic test.
Results: There were about 18 women (1.98%) tested positive to syphilis. Prevalence rates in urban and rural areas were 2.63% and 1.32% respectively. The women from urban areas had a 3.22 (95% CI 1.05‑9.85) increased risk of acquiring syphilis when compared to the rural dwellers. Women with tertiary level of education had a significantly reduced risk of acquiring syphilis compared to those with primary level education while having an unemployed husband increased the risk of acquiring the infection by 10 times.
Conclusion: Though VDRL is part of routine antenatal care screening, a policy of its use in the screening of all women receiving antenatal care in Akwa Ibom state should emphasized and it should be incorporated into the state Government’s free antenatal care program. Preferably, a single rapid test should be employed for screening, so that women testing positive could be treated at same clinic visit. Economic empowerment of women should be accorded priority and the practice of safe sex and use of contraception, especially barrier methods should be promoted
A molecular and parasitological survey of Hepatozoon canis in domestic dogs in Turkey
In this study, asymptomatic dogs in nine provinces of Turkey were surveyed to investigate
the prevalence and intensity of Hepatozoon canis infection. DNA obtained from blood
samples collected from 694 domestic dogs (243 stray, 288 shelter, and 163 pets) of both
genders and varying ages were evaluated by polymerase chain reaction (PCR). In addition,
285 thin blood smears prepared from these blood samples were also evaluated for
microscopic examination. Direct microscopy revealed Hepatozoon gamonts in the peripheral
blood of three of 285 (1.0%; 95% confidence interval (CI): 0.21–3.04) tested. Using PCR,
155 of the 694 (22.3%; 95% CI: 19.28–25.61) were found to be positive for the presence of H.
canis DNA. The prevalence of infection was higher in adult dogs (26.2%; 95% CI: 22.1–30.7)
than young animals (16.4%; 95% CI: 12.2–21.3). Although the prevalence determined by
PCR was higher in male dogs (24.5%; 95% CI: 19.6–29.9) than in female dogs (20.8%; 95%
CI: 16.9–25.1), gender differences were not significant. Pet dogs had a lower prevalence of
infection (10.4%; 95% CI: 6.2–16.2) compared to stray (26.3%; 95% CI: 20.9–32.3) and shelter
dogs (25.7%; 95% CI: 20.7–31.1), but no significant association between stray and shelter
dogs was found for the presence of the parasite. Partial sequences of the 18S ribosomal RNA
(rRNA) gene shared 99–100% similarity with the corresponding H. canis isolates. This epidemiological
survey revealed a high prevalence of H. canis in dogs from several provinces
in Turkey, and it suggests that the age and origin are associated with the parasite
Molecular detection of tick-borne rickettsial and protozoan pathogens in domestic dogs from Turkey
Background: Canine tick-borne parasites have emerged in recent years, showing a wider geographic distribution
and increased global prevalence. In addition to their veterinary importance, domestic dogs play an important role
in the transmission cycles of some agents by acting as reservoirs and sentinels. This study investigated Babesia,
Theileria, Anaplasma, and Ehrlichia species in asymptomatic dogs in ten provinces of Turkey.
Methods: DNA obtained from blood samples collected from 757 domestic dogs (243 stray, 351 shelter, 163 pet)
of both sexes and various ages were evaluated using PCR and reverse line blotting (RLB) assays.
Results: Of the 757 dogs tested, 41 (5.4%) were found to be infected with one or more parasites. Ehrlichia canis
(37/757, 4.9%) was the most common canine tick-borne pathogen, followed by Anaplasma platys (4/757, 0.5%).
Babesia canis and Theileria annulata were each detected in 1 (0.13%) sample. Combined infection of E. canis and
A. platys was detected in 2 (0.3%) samples. The prevalence of tick-borne pathogens was higher in adult dogs
(6.8%) than in those under one year old (3.1%). Difference in infection rate of male and female dogs was not significant.
Pet dogs had a lower prevalence of infection (1.2%) compared to stray (7.4%) and shelter dogs (6%) although the
difference between stray and shelter dogs was not significant.
Conclusions: Babesia canis, T. annulata, A. platys, and E. canis species were identified at the molecular level in
dogs in several provinces of Turkey, with E. canis being the most common species among tick-borne pathogens.
Detailed studies should be conducted regarding the existence and prevalence of B. canis and Dermacentor reticulatus
in eastern Turkey
THE EFFECTS OF HYDROGEN PEROXIDE BLEACHING ON THE STRENGTH PROPERTIES OF RAPHIA HOOKERI CHEMI-MECHANICAL PAPER
The effects of hydrogen peroxide bleaching on the strength properties of Raphia hookeri Chemi-mechanical Paper (CMP) had been investigated. The raphia piassava were reduced to match-stick sized chips manually. The raphia chips were impregnated with a mixture of sodium hydroxide and sodium sulphite for 30 minutes. The chips were beaten and refined to a freeness of 202 CSF. Half of the stock was bleached using 1.39% hydrogen peroxide on Borne-dry (BD) pulp. The bleached and unbleached R. hookeri pulp were formed into paper sheets and tested for physical strength properties. The result showed that there was 17.51% brightness gain for the bleached R. hookeri CMP. Secondly, there was slight reduction in the tear strength (from 880 to 778.67mN), tensile strength (from 20.05 to 2.01 kNm-1) and percentage stretch (from 2.56 to 1.83) of the bleached R. hookeri CMP due to the effects of hydrogen peroxide on the fibres.
 
Intrauterine adhesions in the University of Uyo Teaching Hospital, Uyo, South-South, Nigeria: A ten year review
Background: Asherman's syndrome is a clinical entity that can cause menstrual abnormalities and infertility.
Objectives: This study was done to determine the risk factors, and management outcome of intrauterine adhesions in our hospital.
Subjects and Methods: We carried out a retrospective study of the patients who were treated for intrauterine adhesions at the University of Uyo Teaching Hospital over a 10 years period-from January 1st 2006 to December 2016.
Results: During the study period, a total of 1977 gynecological surgeries were performed of which 83 were for intrauterine adhesions, giving a rate of 4.2%. However, only 52 folders were retrieved, giving a retrieval rate of 62.5%. Analyses, using ratios and percentages, was based on these. Most patients belonged to the 30-34 age group (28.9%) followed by the 20-24 age group (25.0%). The majority of the patients were nulliparous (58.9%), married (65.4%) and had a tertiary education (50.0%). Dilatation and curettage for induced abortion (42.3%), open myomectomy (26.9%), and caesarean section (19.2%) were the common risk factors. Amenorrhoea (65.4%), and hypomenorrhoea (30.8%) were the commonest modes of presentation. All the patients were managed by blind adhesiolysis, done overwhelmingly by the resident doctors, under anaesthesia with a significant percentage (65.3%) showing that there is no change in menstrual condition.
Conclusion: Ashermans syndrome is a relatively common condition, and it is necessary to train doctors in the use of, and acquire, a hysteroscope, for the proper management of this condition. Meanwhile, more senior personnel should be involved in the blind adhesiolysis, and Foley catheter that appears superior as a uterine splint to the intrauterine contraceptive device
