Some Histological Changes in the Intestines of Alloxan Induced Diabetic Mellitus Albino Rats

Changes in intestinal histology of the Albino rats with alloxan induced diabetes mellitus was investigated using fifteen (15) albino rats. The rats were divided into 3 groups A, B, C. Group A served as the control group, group B served as the experimental low dose treated with 100mg/bw of Alloxan, while group C served as the experimental high dose was treated with 200mg/bw of Alloxan. The small intestines were removed and passed through routine tissue processing. The results in the rat of the control group A showed the mucosa, sub-mucosa, muscle and serious layer, luminar surfaces of the villi were lined by simple columnar cells. The brunner glands were also seen in the submucosa. While in rat of group B (low dose); the brunner glands appear to have decreased in size and number of goblet cells appeared more columnar. The histology of the layer was almost as similar to that of the control group. Group C (high dose); whereas in rats in group C was degeneration of the brunner glands characterized by pale staining cytoplasm; the nuclei of the columnar cells of the villi appear pykonotic; there was also loss of villi; the sub-mucosa coat appears to have undergone fibrotic changes; and, the various layers appear indistinct. Our results suggest that high dose of alloxan causes degeneration of the various layers of the duodenum. Keywords: Alloxan, Diabetes mellitus, Wistar rats, Histological change

Bank Portfolio Structure and Absorption Theory of Economic Development: A Theoretical Proposition

The focus of this article was on theoretical proposition of Bank Portfolio Structure and Economic Absorption Theory of economic development. Specifically, this work sought to establish the basis of bank portfolio rigidity and to identify the causes of economic absorption problems and their implications on economic development. The theoretical and conceptual research designs were used. Existing literatures were reviewed using archival retrieval approach, library search and internet exploration. The information obtained was judgmentally, logically and qualitatively analyzed. It was discovered among other aspects, that, bank portfolio rigidity stems from regulatory policy defects using inconsistent monetary policy tools such as high liquidity ratio and cash ratio, etc. and compelling the banks to adhere to the regulatory requirement, as well as lack of adequate and quality stock of infrastructure and technology as the basic causes of economic absorption problems. Above all, low level of economic absorption has been discovered to hinder effective contributions of banks to economic development. Following from above, it was therefore recommended that regulatory tools used by Central Banks should be aligned with the development needs of the economy and the direction of governments. The monetary policy tools such as liquidity and cash ratios should also be moderated and stabilized for stable bank portfolio performance as well as aggressive improvement in the stock and quality of infrastructure and technology within an economy. With the new theory, it is expected that policy formulations and adjustments concerning bank portfolio structure and management would be designed with adequate flexibility and focus on long term loans and investments coupled with improved stock and quality of infrastructure to enhance economic development. This theory therefore provides another frontier of research on bank portfolio structure and contributions to economic development.

Clinical characterisation and management outcomes of COVID-19 infection in pregnancy in a Nigerian tertiary hospital

Background: Literature on the antenatal and perinatal management and outcomes of COVID-19 infection in pregnancy in Nigeria and sub-Saharan Africa is gradually emerging but sparse. There is an urgent need to build up the knowledge base of COVID-19 infection in Nigerian pregnant women. The objective of the current study was to determine the clinical characteristics and management outcomes of COVID-19 infection in pregnancy at the Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife, Nigeria.Methods: A one-year retrospective review of all cases of COVID-19 infection in pregnancy managed at the OAUTHC. Relevant data were extracted from the case records of all cases managed using a purpose-designed proforma. Data collected was analysed using IBM-SPSS, version 24. Associations between categorical variables were assessed using chi square, with level of significance set at <0.05.Results: A total of 22 cases were managed. Majority (15, 68.2%) of the women were either asymptomatic or had mild symptoms. The commonest symptom was cough (8, 36.4%). The mean duration of admission was 6.6±4.2 days. The most common maternal and perinatal complication was preterm delivery/birth (3, 13.6%). There was no maternal mortality. The mean birth weight of the babies was 3226g±597g, with mean 1- and 5- minutes Apgar scores of 8.0±1.3 and 9.5±0.6 respectively.Conclusions: Although COVID-19 infection in pregnancy is an asymptomatic or mild infection in the majority of cases in Ile-Ife, Nigeria, it is associated with adverse maternal and perinatal outcomes. Further studies are recommended to determine transplacental transmission of COVID-19 infection and antibodies

Trends in vaginal hysterectomy in a Nigerian teaching hospital: A 14-year review

Background: The procedure of vaginal hysterectomy is a fast disappearing art. This study looks at 14 years’ experience of vaginal hysterectomy in Ile‑Ife, Nigeria.Objectives: To determine and compare the rate, indications, and complications of vaginal hysterectomy over a 14-year period at Ile‑Ife, Nigeria.Methods: The medical records of patients managed with vaginal hysterectomies performed from 1st January 2005 to 31st December 2018 were reviewed. The demographics and indications for vaginal hysterectomy were extracted. Data were analyzed using Statistical Package for Service Solutions – IBM version 22. Frequencies and percentages were calculated and associations compared where applicable using Chi‑square with level of significance set at &lt;0.05.Results: Pelvic organ prolapse accounted for 0.8% of gynecological admissions and vaginal hysterectomy accounted for 2.3% of major&nbsp; gynaecological operations. The mean age was 66.1 ± 9.2 years with a mean age of menopause of 15.2 ± 7.1 years. The mean parity was 6.2 ± 1.6. Pelvic organ prolapse was the commonest indication. The mean blood loss at surgery was 314.2 ± 184.8 ml. The modal post‑operative complication was post‑operative anemia, and hypertension was the commonest comorbidity. The mean duration of surgery was 3 ± 0.9 h and the mean duration of admission was 5.4 ± 2.7 days.Conclusion: The rate of vaginal hysterectomy is on the decline. This may be due to case under reporting, limiting of family size, or low uptake of farming occupation in our society. Key words: Comorbidities; complications; incidence; indications; vaginal hysterectomy

FIGO best practice guidance in surgical consent

Obtaining medical consent preoperatively is one of the key steps in preparing for surgery, and is an important step in informed decision making with the patient. According to good medical practice guidelines, doctors are required to have the knowledge and skills to treat patients as well as inform them, respect their wishes, and establish trust between themselves and their patients. Valid consent includes elements of competence, disclosure, understanding, and voluntariness. Documentation of these elements is also very important. The International Federation of Gynecology and Obstetrics (FIGO) Education Communication and Advocacy Consortium (ECAC) has realized that the quality of consent varies considerably across the world and has developed simple guidelines regarding consent and procedure-specific checklists for the most common obstetric and gynecological procedures

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Role of academia in enhancing technology and innovation for a post COVID-19 recovery and growth

The COVID-19 pandemic represents one of the greatest challenges of this century with wide ranging impacts not only on health but practically every sector of the human society. The pandemic stretched our resources and coping capacities to almost breaking points even in wealthy economies and further exposed crucial weaknesses in infrastructure, human resources and emergency preparedness of most nations. This review article explored the role of technology and innovation in post COVID-19 growth and recovery.The academia has facilitated better understanding of the COVID-19 pandemic by increasing the body of knowledge on the disease. Better understanding of the disease informed technology and innovations which has made it possible to end the pandemic lockdown, and chart the course for recovery and growth.Relevant articles from a search of electronic databases were reviewed and the role of academia as well as some of the innovations that opened the pathway for recovery were highlighted.Recovery and growth after the COVID-19 pandemic will require synergistic efforts between the academia and the industry, more like taking the “Gown” to “Town”. Research and development in academia, and industrial technology and innovation are veritable tools for a post COVID-19 recovery

Suspected pulmonary embolism postcesarean section in a patient with autosomal dominant polycystic kidney disease

Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetically inherited kidney disease worldwide. It is however relatively underdiagnosed in Africans because its diagnosis is often incidental. During pregnancy, ADPKD is associated with increased risk of preeclampsia and venous thromboembolism. The case of a 33‑year‑old lady incidentally diagnosed with ADPKD during pregnancy is presented. She developed preeclampsia at term and had cesarean delivery of twins. She however suffered cardiopulmonary arrest postoperatively and this created a treatment dilemma because therapeutic anticoagulation which was the primary treatment for her suspected pulmonary embolism was absolutely contraindicated if the actual cause of her collapse was ruptured cerebral aneurysm which was also a feature of ADPKD. We decided to resuscitate aggressively and perform an urgent cranial computed tomography which ruled out intracranial hemorrhage. We then commenced anticoagulation and she made an excellent recovery. This case illustrates the importance of a timely multidisciplinary approach to patient management
