Probiotic Properties of Lactic Acid Bacteria Isolated from Spontaneously Fermented Kunun-Zaki

This study was conducted to investigate the probiotic properties of twenty lactic acid bacteria (LAB) previously isolated and identified from naturally fermented kunun-zaki (a Nigerian fermented cereal beverage). The probiotic properties of the twenty lactic acid bacteria (LAB) isolates were assessed using different standard methods and agar well diffusion method. The results showed that most of the isolates tolerated acidic pH and survived at 30-40oC. All the tested LAB isolates grew at 1% NaCl concentration and remarkably, six LAB isolates {L. brevis (3) and L. plantarum (3)} exhibited good growth at higher NaCl concentrations (10-15%). The highest percentage of cellular auto-aggregation was observed in L plantarum (84.86%) and the lowest was obtained in L. brevis (27.44%). All the twenty LAB isolates tested in-vitro in this study grew in bile salt; fermented glucose; produced good aroma; produced no hemolysis revealing they were not pathogenic and produced antagonistic activity against selected pathogens (Staphylococcus aureus, Salmonella typhi, Shigella. dysenteriae and Escherichia coli) which made them suitable and safe for human consumption as potential probiotics and for industrial purposes.

Patients’ perception of quality of tuberculosis healthcare service in South West Nigeria

Background: Nigeria has the highest burden of tuberculosis (TB) in Africa and is among the 14 countries in all the 3 world health organization global high-burden countries for TB, TB/HIV and MDR-TB. The aim of this study was to assess patients’ perception of the quality of TB healthcare in Southwest Nigeria Methods: The study utilized the cross-sectional design, and data was collected from drug-sensitive TB clients receiving care at health facilities providing TB healthcare services Results: The average time clients spent to get to TB facilities from home was 23 minutes, the average waiting time was 6.7 minutes, and the average medical visit time was 17 minutes. Sixty-seven percent of respondents strongly agreed that doctors explained medical test result with them and 68.7% strongly agree that they wanted the medical doctors to spend more time with them. The mean score for convenience of accessing drugs was 4.8±0.5 mins, mean score for convenience of accessing laboratory test was 4.7±0.6 mins and mean score for convenience of accessing chest x-ray was 3.8±1.4 mins. Overall, the quality of TB care was perceived to be good. Conclusions: Overall, the quality of TB services is very good from the perspectives of the patient, however, there is need to improve integrated patient-centered TB healthcare services by medical doctors. In addition, access to chest x-ray services should be improved to enhance quality of TB services.

Echocardiographic Evaluation of Patients with Goiter in a Nigerian Tertiary Hospital

Background: Goiter is endemic in iodine deficient areas of the world including Nigeria. Cardiovascular disorder is a cause of morbidity in patients with thyroid diseases. These cardiovascular disorders are more likely to be found in patients with hypothyroid or hyperthyroid goiter. Large euthyroid goiter can potentially compromise respiration with potentials for secondary cardiac changes. Despite these, echocardiography is not a routine assessment of these patients. This study set out to determine the baseline cardiac function in a cohort of patients with endemic goiter using echocardiography. Materials and Methods: A comparative study of One hundred goiter patients presenting consecutively at the out-patient clinic of a tertiary hospital and 50 age and gender matched healthy non-goitrous control subjects. They all had thyroid function tests, cardiovascular evaluation and echocardiography done. Results: The mean ages of the goiter and the control groups were 46.92 + 13.85 and 46.58 + 11.62 years respectively (P=0.8510). The goiter population comprised 12 males and 88 females while the control group had 6 males and 44 females. 47% of the goiter subjects were hyperthyroid, while 44% and 9% were euthyroid and hypothyroid respectively. All the control subjects were euthyroid. Systolic and diastolic dysfunction were seen in 18% and 24% of the goiter group respectively, compared to 2% and 5% of the control group (P<0.0001). Hyperthyroid and hypothyroid subgroups had higher rates of both systolic and diastolic dysfunction. Systolic dysfunction was seen in 6.4%, 4.5% and 100% of the hyperthyroid, euthyroid and hypothyroid subgroups respectively while diastolic dysfunction was seen in 23.4%, 9.2 and 100% of the subgroups. Prevalence of systolic and diastolic dysfunction in the euthyroid and control subjects were 4.5% vs 2% (P=0.1228) and 9.2% vs 5% (P=0.2018). Conclusion: This study concluded that cardiac dysfunction is common in both hypothyroid and hyperthyroid goiter population while the prevalence of cardiac dysfunction in the euthyroid population is not influenced by the presence of goiter. This may suggest that routine echocardiography is unnecessary in patient with euthyroid goiter

Diet containing seeds of Buchholzia coriacea accelerates healing of acetic acid induced colitis in rats

Objective: To investigate the anti-colitic effects of diet containing seeds of Buchholzia coriacea (B. coriacea) on acetic acid induced ulcerative colitis. Methods: Male Wistar rats (70-100 g) were fed with standard diets (control group) or with same diet containing B. coriacea seeds at 12.5% or 25% for six weeks. At the sixth week, colitis was induced by intra-rectal administration of 1 mL/200 g 6% acetic acid. Animals were sacrificed at days 0 (before induction), 1, 3 and 7 post induction to assess disease severity via evaluation of stool consistency, haematological variables and histomorphometry of colon tissues. Results: A significant increase in body weight was observed in the 12.5% B. coriacea fed group compared to the control. B. coriacea significantly reduced stool consistency and microscopic scores. Histological evaluation revealed significantly decreased inflammatory aggregates in B. coriacea fed groups compared to control after colitis induction. There was a significant decrease in packed cell volume, red blood cell and haemoglobin concentration in the control group at day 1 post colitis induction compared to 12.5% B. coriacea fed groups. Neutrophils and white blood cell were also significantly increased after colitis induction in the control group while these were significantly decreased in the B. coriacea fed groups. Conclusions: The addition of B. coriacea seeds to diets promotes healing of acetic acid induced colitis by suppressing infiltration of inflammatory aggregates and ameliorating anemia.

Primary health workers' knowledge and practices relating to neonatal jaundice in Ibadan, Nigeria

Background: Over half of births and newborn care occur in primary healthcare facilities in Nigeria, but information on activities of personnel working there is scarce. Aim: To assess the knowledge and practices relating to neonatal jaundice (NNJ) among community health workers (CHWs) and community birth attendants (CBAs) in Nigeria. Setting: We conducted a cross-sectional survey of all 227 CHWs and 193 registered CBAs in Ibadan, Nigeria.Methods: Knowledge and practices regarding NNJ were measured using a pretested questionnaire. Knowledge and practices were assessed on a 33-point scale and a 13-point scale, respectively. Scores ≤ 17 and ≤ 9 was regarded as poor knowledge and as wrong practice, respectively. Results: Many (64.5%) of the respondents could not correctly describe examination for NNJ (CHWs: 49.4%; CBAs: 50.6%). Of the 200 (47.6%) who treated NNJ 3 months prior to the study, 62.5% (CHWs: 66.9% and CBAs: 53.7%) treated NNJ with orthodox drugs. Drugs prescribed included: antibiotics (93.3%), antimalarials (5.3%), multivitamins (28.0%), paracetamol (6.2%) and phenobarbitone (7.1%). Significantly more CHWs than CBAs practiced exposure to sunlight (33.1% versus 16.4%) and administration of glucose water (28.6% versus 14.9%), while 58.0% of all respondents referred cases to secondary health facilities. Overall, 80.2% had poor knowledge (CHWs: 78.9%; CBAs: 81.9%) and 46.4% engaged in wrong practices (CHWs: 57.3%; CBAs: 33.7%). CHWs were more likely to indulge in wrong practices than CBAs (OR = 2.22, 95% CI = 1.03, 4.79). Conclusion: Primary Health Workers in Ibadan had poor knowledge and engaged in wrong practices about NNJ. The needs to organise regular training programmes were emphasised

Current practice of ophthalmic anesthesia in Nigeria

To assess the current techniques of ophthalmic anesthesia in Nigeria A cross sectional survey among Nigerian ophthalmology delegates attending the 36[th] Annual Scientific Congress of the Ophthalmology Society of Nigeria. Self administered and anonymous questionnaires were used and data were collected to include details of the institution, preferred local anesthesia techniques, the grade of doctor who administers the local anesthesia, complications, preferred facial block techniques [if given separately], and type of premedication [if used]. Out of the 120 questionnaires distributed, 81 forms were completed [response rate 67.5%]. Out of the 74 who indicated their grade, 49 [66.2%] were consultants, 22 [29.7%] were trainees, and 3 [7.1%] were ophthalmic medical officers. For cataract surgery, peribulbar anesthesia was performed by 49.1% of the respondents, followed by retrobulbar anesthesia [39.7%]. Others techniques used were topical anesthesia [5.2%], subtenon anesthesia [4.3%], subconjunctival anesthesia [2.6%], and intracameral anesthesia [0.9%]. For glaucoma surgery, 47.2% of the respondents use peribulbar anesthesia, 32.1% use retrobulbar anesthesia, 9.4% used general anesthesia, and 6.6% used subconjunctival anesthesia. Among the trainees, 57.8% routinely perform retrobulbar anesthesia while 55.6% routinely perform peribulbar anesthesia. At least one complication from retrobulbar anesthesia within 12 months prior to the audit was reported by 25.9% of the respondents. Similarly, 16.1% of the respondents had experienced complications from peribulbar anesthesia within the same time period. Retrobulbar hemorrhage is the most common complication experienced with both peribulbar and retrobulbar anesthesia. Presently, the most common technique of local anesthesia for an ophthalmic procedure in Nigeria is peribulbar anesthesia, followed by retrobulbar anesthesia. Twelve months prior to the study, 25.9% of the respondents had experienced at least one complication from retrobulbar anesthesia and 16.1% from peribulbar anesthesia. Retrobulbar hemorrhage was the most common complication reported
