We report the treatment of a 48-year-old man who developed unilateral left rhinorrhea after a nasopharyngeal swab sample. It is aimed to draw attention to this complication that can be prevented with the appropriate technique during nasopharyngeal swab sampling.展开更多

Pregnant women that presented with vaginal candidiasis constituted 40%(n=360) of the total 840 cases.Other risk groups included the immuno-suppression with 24%(n=202),group on hormonal therapy with 15%(n=126) and broad spectrum antibiotics users with 16%(n=134).Conclusions: The results show that Candida is the most common cause of vaginitis and vulvo-vaginal candidiasis followed by C.albicans in the young adults aged 21 to 30 years,pregnant mothers, immuno-suppression,contraceptive and broad spectrum antibiotic users.Proper management of vaginal candidiasis and vulvo-vaginal candidiasis is recommended especially among the risk groups in order to avoid complications and reduce HIV transmission.展开更多

This may be a predisposing factor to infections in the urogenital system. This study aimed to assess the endocervical swab microscopy, culture and sensitivity in patients with third degree uterovaginal prolapse at the National Obstetric Fistula Centre, Abakaliki, South-East Nigeria. Methodology: This is a cross-sectional prospective study to assess the endocervical swab microbial findings in patients with third degree uterovaginal prolapse using simple random sampling technique. Data on sociodemographic variables, risk factors for pelvic organ prolapse, and endocervical swab findings among women with third degree uterovaginal prolapse were collated and analysed using statistical methods. Results: The mean age and parity were 50.5 years ± 9.1 and 6.7 ± 2.0 respectively. Thirty-six (85.7%) of the clients were grandmultipara and 37 (88.1%) were farmers. Pus cells were present in all samples while 27 (64.3%) had microbial isolates. Streptococcus pyogenes was isolated in 7 (16.7%), Streptococcus faecalis in 5 (11.9%), Escherichia coli in 5 (11.9), Staphylococcus aureus in 4 (9.5%), Klebsiella pneumoniae in 2 (4.8%) and Yeast cells in 4 (9.5%) of the endocervical swabs. All isolates were sensitive to gentamicin. Bacterial isolates were resistant to amoxicillin/clavulanic acid. Conclusion: This study showed growth of pathogenic organisms from the endocervix of women with third degree uterovaginal prolapse. A 100% sensitivity to gentamicin was observed in the study.展开更多

Science has managed, in a short time, to characterize a new disease, sequence a new viral genome, develop diagnostics, produce treatment protocols and establish the efficacy of drugs and vaccines in randomized controlled trials. In this paper we have dealt with different topics regarding the pandemic linked to COVID-19. Objectives: Aim of this paper is to compare the number of deaths attributable to COVID-19, that occurred in the different Italian macro-areas, in the different pandemic waves;we studied the trend of the curves relating to the proportion of deaths to the number of infected in the Italian macro-areas for the pandemic waves and analysed the mortality data, focusing on the Italian context and comparing it with other foreign countries. We examined the data regarding swabs, hospitalizations, home isolation, admissions to intensive care and deaths registered in pandemic period. Results: Geographically, Italy was differently affected by the pandemic. Northern Italy was the most affected area. In comparison with some foreign countries, Italy is one of the nations that paid the most in terms of deaths, due to: delays in understanding the seriousness of the emergency;the slow management in the tracking systems of contagions;the high number of hospitalizations;a corporate organizational system poorly planned. Conclusion: The years 2020 and 2021 have been dramatic and unprecedented. The year 2021 was the year of redemption, where, despite social, economic and health difficulties, thanks to mass vaccination, we were able to give a real strong response to the pandemic. Trust in science has led to a drastic decrease in mortality throughout the world.展开更多
