The solid foundation laid by Prof Theophilus Oladapo Ogunlesi and other founding fathers of the National Postgraduate Medical College of Nigeria (NPMCN) has consistently achieved its mandate of producing specialist medical practitioners in Nigeria. The ever-changing world requires that we have in Nigeria a critical mass of subspecialists to tackle the various old and emerging ailments that afflict the citizenry. Subspecialist training is popular among Nigerian specialists. While those who are not yet subspecialists crave for the training. Nigerian-born sub-specialists in the diaspora are willing to assist in the training. It is now left to policy makers and captains of the training institutions to seize the chance and move us forward with a view to improving the current embarrassingly low number of subspecialists in Nigeria. The NPMCN is hereby beckoned to take the lead. In doing so, it should combine excellence with relevance.

The National Health Insurance Scheme (NHIS) faced several inherent and systemic drawbacks towards achieving universal health coverage for all Nigerians, and this has led to the signing of the new National Health Insurance Authority Act (NHIA), 2022. This article highlights the benefits of NHIA, discusses the possible challenges and the way forward in its implementation. A narrative review of past literature searched in PubMed, MEDLINE, African Journal Online, and Goggle was conducted. A total of 76 publications were initially retrieved and following data triangulation, 55 were finally used. The authors also included their experiences. The NHIA addressed some of the shortcomings of the previous NHIS, however, it would still face several challenges in its implementation such as low government funding priority to health, shortage of healthcare workers and poor healthcare coverage, as well as problems with enforcement as it mandates all Nigerians to enroll. These and other impending constraints must be surmounted and all stakeholders must be involved to ensure the Act accomplishes its aim.

A 15-year-old boy came to the eye clinic with reduced vision in the left eye of a year's duration and prior trauma. Best-corrected visual acuity was 6/9 and hand movement in both eyes, respectively. The anterior segment examination was essentially normal except for a Marcus Gunn pupil and a polar cataract in the left eye. Goldmann applanation tonometry was 10 and 06 mmHg, respectively, in the right and left eyes. Binocular indirect ophthalmoscopy of the right eye revealed pink disc, normal vessels and the Mizuo-Nakamura phenomenon with a cartwheel appearance at the macula. The left eye had a total retinal detachment with proliferative vitreoretinopathy and retinal tear at 12 o' clock. Optical coherence tomography revealed posterior vitreous detachment and schitic cavities at the macula in the left eye. A diagnosis of left rhegmatogenous retinal detachment with background X-linked juvenile retinoschisis was made. The patient was advised on a pars plana vitrectomy under guarded visual prognosis.

The coronavirus disease-19 pandemic has spread to all parts of the world. As of 20 May 2022, over 500 million confirmed cases have occurred with over 6 million deaths. In Nigeria, over 255,000 cases have occurred with more than 3000 deaths. The pandemic has adversely affected virtually all aspects of human endeavour, with a severe impact on the health system. The Nigerian health system was ill prepared for the pandemic, and this further weakened it. The impacts of the pandemic on the health system include disruption of health services, low motivation of the health workforce, unresponsive leadership and poor funding. The national response, though initially weak, was ramped up to expand capacity building, testing, public enlightenment, creation of isolation and treatment centres and research. The funding for the national response was from the government, private sector and multilateral donors. Nigeria must comprehensively strengthen its health system through motivating and building the capacity of its human resources for health, improved service delivery and provision of adequate funding, to be better prepared against future pandemics.

Carbapenemase-producing Enterobacteriaceae (CPE) have become one of the greatest public health challenges globally. In the past decade, antimicrobial resistance (AMR) was viewed as a clinical problem in many parts of the world; hence, the role and magnitude of the contribution of the environment were not well appreciated. This review article was done with online published articles extracted from different databases using search terms related to the work. Evidence has shown that there exists the presence of carbapenemase genes in the environment, consequently fuelling the dissemination with alarming consequences. CPE when acquired causes life-threatening infections in humans. The health and economic impact of these infections are numerous, including treatment failure due to limited therapeutic options which hamper the containment of infectious diseases, further contaminating the environment and worsening the public health challenge. It is a well-known fact that the rate of emergence of resistant genes has outpaced the production of new antimicrobial agents, so it is pertinent to institute effective environmental measures to combat the spread of AMR organisms before it will completely gain a foothold and take us back to 'the pre-antibiotic era'. Environmental sources and reservoirs of resistant genes should therefore be amongst the primary targets for the control and prevention of the spread of resistant genes in the environment. This calls for the effective implementation of the 'one health' strategy with stakeholders committed to the design and enforcement of environmental mitigation policies and guidelines.
