An overview of intensive care unit services in Nigeria.

PURPOSE: To have a current overview of the state of critical care services in Nigeria, with a view to having information about the basic infrastructure, personnel, equipment, and processes in place to complement the acute peri-operative and medical emergencies in Nigeria. MATERIALS AND METHODS: This was a cross-sectional survey of public and private intensive care units (ICUs) in Nigeria at the instance of the Intensive and Critical Care Society of Nigeria. Structured questionnaires were sent and collated over a 4-month period. Information on the institutions, ICU equipment and personnel were collected and analyzed using SPSS version 21(Chicago, Illinois). Data are presented in numbers, percentages, medians, and interquartile ranges (IQR) as appropriate. RESULTS: A total of 30 ICUs spread within all the six geo-political zones in Nigeria took part in this survey. Majority (63.3%) of them were located in teaching hospitals. The median number of ICU beds and equipment in hospitals surveyed were beds, 5(4-6), ventilators, 3 (1-4); multiparameter monitor, 4 (3-5.25) and arterial blood gas machine, 0(0-1). The anaesthetists led in running 90% of the units. CONCLUSION: This survey showed a low ICU bed capacity and deficits in basic and advanced haemodynamic monitoring equipment. There is also shortage of trained ICU Physicians.

Nigerian surgical outcomes - Report of a 7-day prospective cohort study and external validation of the African surgical outcomes study surgical risk calculator.

BACKGROUND: Surgical outcomes study for individual nations remains important because of international differences in patterns of surgical disease. We aimed to contribute to data on post-operative complications, critical care admissions and mortality following elective surgery in Nigeria and also validate the African Surgical Outcomes Study (ASOS) surgical risk calculator in our adult patient cohort. MATERIALS AND METHODS: We conducted a 7-day, national prospective observational cohort study in consented consecutive patients undergoing elective surgery with a planned overnight hospital stay following elective surgery during a seven-day study period. The outcome measures were in-hospital postoperative complications, critical care admissions and in-hospital mortality censored at 30 days. Also, we identified variables which significantly contributed to higher ASOS surgical risk score. External validation was performed using area under the receiver operating characteristic curve (ROC) for discrimination assessment and Hosmer-Lemeshow test for calibration. RESULTS: A total of 1,425 patients from 79 hospitals participated in the study. Postoperative complications occurred in 264(18.5%, 95% CI 16.6-20.6), 20(7.6%) of whom were admitted into the ICU and 16(6.0%) did not survive. Total ICU admission was 57 (4%), with mortality rate of 23.5% following planned admission and overall in-hospital death was 22(1.5%, 95% CI 0.9-2.2). All prognostic factors in the ASOS risk calculator were significantly associated with higher ASOS score and the scoring system showed moderate discrimination (0⋅73, 95% CI 0.62-0.83). Hosmer-Lemeshow χ2 test revealed scale was well calibrated in the validation cohort. CONCLUSION: NiSOS validates the findings of ASOS and the ability of the ASOS surgical risk calculator to predict risk of developing severe postoperative complications and mortality. We identified failure-to-rescue as a problem in Nigeria. Furthermore, this study has provided policy makers with benchmarks that can be used to monitor programmes aimed at reducing the morbidity and mortality after elective surgery. We recommend the adoption of the ASOS surgical risk calculator as a tool for risk stratification preoperatively for elective surgery.

Blood cellular markers of inflammation in Breast Cancer and response to Neoadjuvant Chemotherapy

Background:Breast cancer is the most common female malignancy in Nigeria. Neoadjuvant chemotherapy is the first line treatment for locally advanced breast cancer. The advancement of many cancers is accompanied by inflammation, and inflammatory cells play an essential role in the progression.Objective:To determine if haematological parameters can predict the responsiveness of breast cancer to neoadjuvant chemotherapy regime.Method:A prospective cohort study of all breast cancer patients who had neoadjuvant chemotherapy betweenJuly 2017 andDecember 2018was carried out. Haematological parameters of red cell count (RCC), white cell count(WCC), neutrophil count (NC), lymphocyte count (LC), platelet count (PC), red cell distribution width (RCDW), mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were measured. Response to chemotherapy was assessed by measuring the longest diameter of the lump and largest lymph node and applying the UICC criteria.Results: Thirty-five females with breast cancer with the age range of 33-82 years and mean age of 48± 11yearswere studied. The overall clinical response rate was 80% consisting of 40% complete clinical response, 40% partial clinical response, 8.6% stable disease and 11.4% progressive disease. Eleven (78.6%) with PLR values below average had good clinical response while 21.4% of those with PLR value above average had a good clinical response(χ2= 8.4, p =0.006)Conclusion: The study showed that PLR is associated with complete clinical response to neoadjuvant chemotherapy and should be used as part of routine assessment before chemotherapy

Large penile plexiform neurofibroma in an 11-year old boy.

Background: Neurofibromatosis is a genetically inherited disorder of the nervous system (brain and spinal cord) which mainly affects the development of nerve (neural) cell tissues, causing tumors (neurofibromas) to develop on nerves. It is the most common single gene disorder of the nervous system and inheritance is through autosomal dominance. They are usually classified into types 1 and 2, the type 1 is the commoner type and also known as superficial neurofibroma. Plexiform neurofibromas are the next most common type of tumor in individuals with type 1 neurofibroma. Plexiform neurofibromas are histologically benign tumors that are made up of a variety of cell types including neuronal axons, Schwann cells, fibroblasts, mast cells, macrophages, perineural cells and extracellular matrix materials such as collagen. They can occur in any part of the body and can grow throughout the person's lifetime, often becoming disfiguring, disabling or deadly via compression of vital structures or conversion to a malignant sarcoma or malignant peripheral nerve sheath turmor. The aim of this report is to present a large penile plexiform neurofibroma which required extensive dissection for complete excision and reconstruction of the phallus and glans penis. Objectives: To present a huge penile plexiform neurofibroma and the mode of surgical treatment. Methods: The huge penile plexiform neurofibroma was completely excised and the penile defect resulting from the excision was repaired. Conclusion: Plexiform neurofibromas are congenital tumors of peripheral nerve sheaths which may also develop near nerve roots deep within the body. They are usually benign but carry a malignant potential in 5-10% of patients. Plexiform neurofibromas are commoner in the face, chest and limbs but the index case occurred on the penile shaft.
