Aim: Microorganisms are ubiquitous in the built environment and their presence has been documented to have adverse effect on the users of such buildings. This study was conducted to assess the Bioaerosol concentrations of selected offices. Study Design:  A random sampling technique was adopted to select the eight (8) offices for the study based on accessibility and visitation. Place and Duration of Study:    The study was carried out in selected offices within Captain Elechi Amadi Polytechnic, Rumuola, Port Harcourt.            Methodology:   Sedimentation technique was employed for the assessment involving Nutrient Agar, Mac Conkey Agar and Potato Dextrose Agar. The analysis was replicated thrice for both morning and afternoon sessions Results: The results reveal that the mean total heterotrophic bacterial counts ranged from 5.85 x 103cfu/m3 (SUG Office) to 3.80 x 104 cfu/m3 (Lecturer Office 2) for the morning session while the afternoon session ranged from 1.13 x 104 cfu/m3 (SUG Office) to 6.54 x 104 cfu/m3 (Lecturer Office 2). The mean total coliform counts for the morning session ranged from 1.17 x 104 cfu/m3 (ICE Office) to 4.07 x 104 cfu/m3 (Lecturer Office 2) while the afternoon session ranged from 7.87 x 103 cfu/m3 (Admission Office) to 2.40 x 104 cfu/m3 (DSA Office). The mean total fungal counts ranged from 1.24 x 104 cfu/m3 (DSA Office) to 3.91 x 104 cfu/m3 (CSO Office) for the morning session while the afternoon session ranged from 8.87 x 103 cfu/m3 (CSO office) to 5.13 x 104 cfu/m3 (Lecturer Office 2). Conclusion: This shows that the selected offices in Captain Elechi Amadi Polytechnic are being affected by the airborne bacteria and fungi higher than the recommended limit of 103 cfu/m3. This can result in health challenges of the staff and students thereby reducing productivity, hence a need to control factors that increase the presence of bioaerosols and ensure good sanitary practices in offices.

An essential mandate of food and drug regulatory agencies is to ensure that products offered for public consumption are free from such level of microbial contamination as to endanger the health of consumers. A number of herbal remedies offered to the public were found not to be regulated as evidenced by the absence of regulation numbers on the labels. Thus, this study sought to determine the level of bacterial contamination of packaged, labeled, non-regulated herbal remedies sold in Port Harcourt.  Seventy two samples of twelve different locally produced, liquid, packaged, labeled, orally administered, non-regulated herbal remedies were purchased randomly from retail outlets within Port Harcourt metropolis. They were assessed for total heterotrophic bacterial counts (THBC) and total coliform counts (TCC). One hundred and sixty four bacterial strains obtained were characterized and identified by standard techniques employing Gram staining and biochemical methods. The mean THBC was 3.77±0.77 Log10cfu/ml ranging from 3.20±0.99 to 4.37±0.91Log10cfu/ml. The mean TCC was 3.17±1.02 Log10cfu/ml; with the range between 2.32±1.81 and 3.98±0.47 Log10cfu/ml. All 164 bacterial isolates belong to eleven genera, and 22 species namely Staphylococcus aureus (59;36.0%), Enterobacter cloacae (13; 7.9%), Enterobacter pyrinus (10; 6.1%), Klebsiella pneumoniae (10; 6.1%), Pseudomonas aeruginosa (10; 6.1%), Bacillus subtilis, (8; 4.9%) Enterobacter aerogenes (7;4.3%), Serratia rubidaea (7;4.3%), Proteus (Cosenza) myxofaciens (6;3.7%), Staphylococcus epidimidis (6;3.7%) Serratia marcescens  (4;2.4%) Bacillus cereus (3;1.8%), Citrobacter rodentium (3;1.8%), Enterobacter hormaechei, (3;1.8%) Klebsiella oxytoca, (3;1.8%)  Proteus mirabilis (3;1.8%). Hafnia alvei (2;1.2%), Salmonella pullorum (2;1.2%), Streptococcus pyogenes (2;1.2%) Enterobacter cancerogenus (1; 0.6%) Salmonella enterica (1; 0.6%), Salmonella typhi (1; 0.6%). Given that these products were processed, packaged, labeled and offered for sale to the public without regulatory numbers, it is suggested that regulatory agencies should ensure that all such products are brought within the ambits of the regulatory laws.

There is an increasingly high suspicion of occupational health diseases amongst workers in sawmill factories. Hence this study aimed to determine the microbial diversity in some sawmill factories in Okada, Edo State, Nigeria to evaluate potential implications of the factory’s processing area on the health of the workers and wood merchants. Bacteria and fungi count in the bioaerosols within the processing area of each factory was performed with the passive air sampling technique. While in the sawdust samples, microbial counts were carried out with the pour plate technique. Identification of the microbes was performed with macroscopic and microscopic examinations as well as standard phenotypic tests. Mean total viable count (TVC) and total fungi count (TFC) of bioaerosols in the air within the processing area of the sawmill factories were found to be greater than 4162.99 CFU/m3 while mean total coliform count (TCC) was reported as 756.28 CFU/m3. Fisher (F) one-way ANOVA test of the TVC and TCC dataset of bioaerosols from the four sawmill factories indicated no significant difference (p = 0.77 and 0.83 for TVC and TFC respectively) in the mean TVC and TFC of the bioaerosols. Bacterial (Micrococcus, Staphylococcus, Bacillus, Klebsiella and Serratia) and fungal (Saccharomyces, Aspergillus, Cladosporium and Penicillium) species were isolated from the bioaerosols and sawdust samples. Results of this study indicated that workers in the sawmill factories and other wood merchants who visit sawmill processing area are most likely exposed to airborne contaminants that may cause occupational diseases such as ophthalmic irritations and dermatitis. Hence it is recommended that sawmill workers and other visitors wear personal protective gadgets in the processing area of the sawmill factories.

OBJECTIVES: The objective of this study was to compare working length calculated with conventional radiographs and an electronic apex locator (IPEX II) during the root canal treatment of mandibular anterior teeth. METHODOLOGY: A cross-sectional study was done in the Department of Operative Dentistry, Sardar Begum Dental Hospital, Peshawar during February and March 2018. A consecutive sampling technique was used for sampling. Only 30 patients fulfilled the inclusion criteria of our study. Detailed medical and dental history was taken. Only patient fulfilling inclusion criteria were enrolled in the study. Data were analyzed using SPSS version 20. RESULTS: The mean age for patients was 45.33±5.16. 33% out of 30 patients (10) were male and 20 were females. The mean working length calculated from radiographs was 22.25±1.29 (min 20.09-max 24.10). The mean working length calculated by the electronic apex locator (IPEX II) was 22.17±1.28 (min 20.00-max 24.07). The mean difference between working length calculated by radiograph and electronic apex locator was -0.084mm, which means the working length determined by radiographs and by electronic apex locator has no difference in mandibular anterior teeth with single canals. CONCLUSION: Both the methods can be used effectively in endodontics for single-rooted mandibular teeth, but if both are used in combinations can lead to an improvement in the working length accuracy, which may significantly reduce the number of radiographs exposure, and increase the success and comfort for endodontic patients.
