Effect of Intramuscular Hyoscine-N-Butyl Bromide on Tubal Spasm and Pain Perception in Women with Infertility Undergoing Hysterosalpingography: A Randomised Controlled Trial

Background: A tubal patency test is essential in evaluating women with infertility. Hysterosalpingography (HSG) is the investigation of choice for assessing tubal patency. Objective: To evaluate the effect of intramuscular hyoscine-N-butyl bromide on tubal spasms and pain perception during hysterosalpingography. Methods: This randomized, controlled trial was conducted at the Radiology Departments and Infertility Clinics of four health institutions in Bayelsa State, Nigeria, between January 2021 and April 2022. Five hundred and twenty infertile women undergoing hysterosalpingography were randomized into two groups. Women in group I (control) received a placebo, while women in Group II (experimental) received 20 mg of intramuscular hyoscine-N-butyl bromide. Pain scores at different steps of the procedure were recorded. Results: The overall mean pain scores progressively decreased from contrast instillation (4.97 ± 2.08) through 30-minutes post-procedure (3.54 ± 1.54) to 24 hours post-procedure (1.96 ± 1.78). Pain scores at contrast instillation, 30 minutes and 24 hours after HSG were significantly lower in the hyoscine group compared to the placebo group (p = 0.001 each). There were significantly fewer women with tubal blockage in the hyoscine group compared to the placebo group [78 (30.0%) vs 131 (50.4%); p = 0.001]. Conclusion: Intramuscular hyoscine-N-butyl bromide before hysterosalpingography significantly reduces pain and tubal spasm during the procedure

Relationship Between Subchorionic Haematoma and Abdominal Massage in Pregnancy in the Niger Delta Region of Nigeria: A Pilot Study

Background: Abdominal massage (AM) in pregnancy is a common practice in the Niger Delta region of Nigeria. AM may cause events such as subchorionic haematoma (SAH) and increase the risk of miscarriages and adverse maternal and perinatal outcomes. Objective: To determine the relationship between AM and SCH in the Niger Delta region of Nigeria. Methods: A cross-sectional study was conducted from January to June 2022 at the Obstetrics and Radiology Units of four health facilities in Bayelsa State, Nigeria. Consenting eligible pregnant women presenting to the antenatal clinic during the first trimester were consecutively included. An obstetric ultrasound scan was performed transabdominal. Results: Of the 403 women recruited, 241 (59.8%) were aged (20 – 29 years). The mean age was 28.02 ± 5.99 years. The mean body mass index was 23.82±4.60 kg/m2. While 170 (42.2%) had undergone AM in the first trimester of the index pregnancy, 126 (31.3%) had vaginal bleeding, and SCH occurred in 109 (27.0%) women. Women who had AM had 210 (CI: 58 – 878) times the odds of having SCH and 3.3 (CI: 2.14 – 5.15) times the odds of vaginal bleeding than women who did not have AM. Only 2 (1.8%) women with SCH did not have AM. Conclusion: There exists a strong association between the occurrence of SCH among pregnant women who have had AM. More health education is needed for women in the Niger Delta region and Nigeria to eradicate the archaic practice and improve pregnancy outcomes

Cyclophilin B Interacts with Sodium-Potassium ATPase and Is Required for Pump Activity in Proximal Tubule Cells of the Kidney

Cyclophilins (Cyps), the intracellular receptors for Cyclosporine A (CsA), are responsible for peptidyl-prolyl cis-trans isomerisation and for chaperoning several membrane proteins. Those functions are inhibited upon CsA binding. Albeit its great benefits as immunosuppressant, the use of CsA has been limited by undesirable nephrotoxic effects, including sodium retention, hypertension, hyperkalemia, interstial fibrosis and progressive renal failure in transplant recipients. In this report, we focused on the identification of novel CypB-interacting proteins to understand the role of CypB in kidney function and, in turn, to gain further insight into the molecular mechanisms of CsA-induced toxicity. By means of yeast two-hybrid screens with human kidney cDNA, we discovered a novel interaction between CypB and the membrane Na/K-ATPase β1 subunit protein (Na/K-β1) that was confirmed by pull-down, co-immunoprecipitation and confocal microscopy, in proximal tubule-derived HK-2 cells. The Na/K-ATPase pump, a key plasma membrane transporter, is responsible for maintenance of electrical Na+ and K+ gradients across the membrane. We showed that CypB silencing produced similar effects on Na/K-ATPase activity than CsA treatment in HK-2 cells. It was also observed an enrichment of both alpha and beta subunits in the ER, what suggested a possible failure on the maturation and routing of the pump from this compartment towards the plasma membrane. These data indicate that CypB through its interaction with Na/K-β1 might regulate maturation and trafficking of the pump through the secretory pathway, offering new insights into the relationship between cyclophilins and the nephrotoxic effects of CsA

Knowledge, Attitude and Uptake of Pap Smear among Female Healthcare Professionals in a Nigerian Teaching Hospital

Background: Despite the high prevalence of cervical cancer (CC) in Nigeria, the uptake of screening services, including Pap smear, remains poor, even amongst healthcare providers. Objective: To assess Pap smear knowledge, attitude, and uptake among female healthcare professionals (FHPs). Methods: A cross-sectional descriptive study was conducted at the University of Ilorin Teaching Hospital (UITH), Kwara State, Nigeria, using a self-administered questionnaire. Results: A majority (343, 98.6%) of the FHPs knew Pap smear. Five (26.3%) medical laboratory scientists did not know what a Pap smear was. All the nurses, doctors, pharmacists, physiotherapists and medical social workers knew Pap smear. Only a fifth (71; 20.4%) of the FHPs had ever done a Pap smear. The most common reason cited for not having done a Pap smear was lack of time (109; 31.3%). There was a relationship between age and uptake of Pap smear (p = 0.024). Only 188 (54%) of the FHPs had ever recommended Pap smear to other women. Conclusion: Despite the high level of knowledge of Pap smear amongst FHPs in Nigeria, attitude and uptake remain poor. There is a need for further training and education of FHPs on the benefits of CC screening to increase their uptake and improve their effectiveness in promoting positive attitudes towards CC screening and prevention in the general population
