Introduction: The bacteriological diagnosis of tuberculosis is mainly based on the isolation and identification of the responsible mycobacteria. However, the slow growth of mycobacteria remains a real obstacle for studies interested in this disease. Microscopic examination is the initial step and often the only possibility in many developing countries to make the diagnosis. Faced with this problematic, this work focused on evaluating the contribution of centrifugation of the pathological product on the positivity of the microscopic examination and to make a comparison of the cultures of mycobacteria in Löwenstein Jensen (LJ) and in Middlebrook 7H9 (MB7H9) for the bacteriological diagnosis of tuberculosis.
Methods: Over a period of 6 months, all samples for diagnosis of tuberculosis, received at the Bacteriology-Virology-Hygiene laboratory of the IBN ROCHD University Hospital center in Casablanca were included in our work. Middlebrook 7H9 was prepared at our laboratory.
Results: On 613 clinical samples analyzed. The study showed that smear microscopy after centrifugation showed a better yield with a specificity of 100%; it increased the sensitivity of direct examination, allowing a gain of 50%, with a VPP of 100% and a VPN of 97, 56%. The MB7H9 liquid also gave a better yield with a very short growth time compared to the solid LJ.
Conclusion: The implementation of MB7H9 culture technique requires well-adapted structures and its systematic use in bacteriological diagnosis remains dependent on financial resources.

We report the case of a patient admitted to the emergency department in whom the diagnosis of thrombotic thrombocytopenic purpura was made after a series of laboratory and clinical analyzes.
The clinical signs appeared 3 weeks after his second AstraZeneca / Oxford anti-COVID-19 vaccination and worsened after a month. The patient benefited from plasma exchange sessions, targeted therapy based on 4courses of Rituximab, Sodium Valproate 500 mg, and Prednisone 20 mg. Both biological and clinical evolution is favorable from the first week of treatment.
Successful treatment of TTP regardless of its etiological origin is based on plasmapheresis, corticosteroids and Rituximab, and the only treatment that can be offered urgently is plasma exchange.
The onset of PTT along with other clinical signs immediately after AstraZeneca / Oxford vaccination suggests the potential, but unproven, role of AstraZenica vaccination in PTT pathogenicity.

Shoe manufacturing industry is an emerging and hazardous industry involving enormous labor, low variability of the process and highly monotonous tasks leading to work related Musculoskeletal disorder (MSD) symptoms. Therefore, need of implementation of Ergonomic principles in shoe manufacturing has become very important. Ergonomic studies on industrial and operational workers in large number are available in literature but literature regarding physical issues of shoe manufacturing workers is very limited. Therefore, to resolve physical issues in small and medium labor intensive shoe manufacturing industries, need of an ergonomic study was felt, which was conducted in shoe industries of Agra to find out the association between perceived stress and MSDs and influence of psychosocial and biomechanical factors on symptoms related to musculoskeletal disorder. Two types of industries, old conventional and semi-automatic were selected to conduct the study. Total 435 workers were selected. Finally a sample of 266 was selected. The results of the study showed that MSD symptoms in the various parts were found to be associated with age, inappropriate posture, bullying and perceived effort, very low social support, long time of working in the company and perceived effort were associated with the MSD symptoms. Hence, it has been seen that mainly psychosocial factors and biomechanical factors were associated with MSDs and were having large effect on MSD symptoms occurrence.

Stabilization exercises improve muscle performance and are effectively used to alleviate chronic low back pain. The aim of present study is to evaluate and differentiate the magnitude of electromyography activity of erector spinae and external oblique muscles during bridge and pelvic-tilt stabilization exercises. Thirteen healthy males have volunteered in this research. Muscle activity is recorded bilaterally of erector spinae and external oblique with Biopac MP150duringstabilization exercises. Normalized EMG values for erector spinae and external oblique muscles are evaluated as percentage of maximum voluntary contraction. Statistical analysis is performed using one-way ANOVA. The right erector spinae presents the highest activity during bridge exercise, whereas the left erector spinae shows highest activity during pelvic-tilt exercise. Mean activation of erector spinae is higher than that of external oblique during both stabilization exercises. NOVA reveals that bridge exercise produces significantly greater activity as compared to pelvic tilt exercise for for the both sides of erector spinae and the right side of external oblique.The mean activity of both SE viz. erector spinae and external oblique muscles are different in bridge and pelvic-tilt exercises. The findings of this research may be helpful to therapists when guiding a patient through a rehabilitation program for lower back pain, by first selecting pelvic-tilt exercise that produces low levels of electromyography activity in selected muscle and then bridge exercise that induces significantly higher electromyography activity.

This study focused on the applicability of universal basic education in selected primary schools in Calabar Municipality of Cross River State, Nigeria. The implication to Educators in Test, Measurement and Evaluation. To guide the study, three research questions and hypotheses were postulated. In line with the study, the ex-post facto research design, with a population of 7, 234   primary school pupils of universal basic education across 23 primary schools in Calabar Municipality Local Government area of Cross River State, Nigeria out of which are 3,561 males and 3, 673 females. A sample of 224 was drawn from the target population using simple percentages for sample size and the simple random sampling technique was employed in selecting the respondents. An 18-item questionnaire was developed and administered to 224 primary school pupils in 6 primary schools in Calabar municipality while 218 were retrieved. A research questionnaire titled Applicability of Universal Basic Education Programme Questionnaire (AUBEPQ)” was the major instrument used for the study; the instrument was duly validated using internal consistency reliability and it yielded an index of 076 to .86. The research questions were answered and the data collected were analyzed using the mean and standard deviation, while null hypotheses were tested using one sample t-test at 0.05 level of significance. The result showed there was a significant improvement in the level of free and compulsory education in primary schools in Calabar municipality local government area of Cross River State; and the dropout tendency among primary school pupils in Calabar municipality is significantly high; also the level of appropriate literacy skills provided by the UBE programme in the area of study is significantly high. Based on these findings, it was concluded that the objectives of the UBE programme be revisited for effective implementation to curb the dropout tendency among primary school pupils. The study recommended that the UBE programme should be free of payment among other things including the provision of all learning materials for school pupils.

Objective of this study: This questionnaire analysis aimed to state oral manifestations that have been seen in Egyptian infected with (severe acute respiratory syndrome coronavirus 2 – SARSCOV-2) during the pandemic second wave.
Material and methods: patients were asked to fill out a questionnaire about their symptoms in dental clinics and. The questionnaire was completed by 60 patients (43 females and 71 male) aged between (25-55), questionnaire included questions about these symptoms pain related to prosthesis, dryness, mouth burn, candida, inflammation, and the recovery time.
Results: only 30% of patients who completed the survey said they had oral manifestation during infection period, varies between inflammation, dryness, and candida infection and the symptoms sustained after recovery from infection by COVID-19, patients took this survey and had complete dentures mentioned no symptoms related to denture foundation area excepts one patient mentioned problems with denture fit after recovery.
Conclusion: As any part of the body oral cavity has also been affected by the novel COVID-19 viruses, symptom and oral manifestation is still under investigations. Absence or presence of symptoms and its severity varies from one person to another.
