ABSTRACT
Background: Traumatic diaphragmatic injury (TDI) is a relatively rare condition, and there is a high tendency for it to be missed if thorough clinical assessment and imaging review are not carried out. The surgical approach for TDI can be challenging, especially with bowel perforation. Materials and Methods: This is a retrospective case series of all consecutive patients with TDI from two tertiary hospitals in the southern part of Nigeria between January 2013 and December 2019. The demographic data of the patients, type, cause, and clinical diagnosis, intraoperative findings, Injury Severity Score, and outcome were noted. The descriptive statistics were presented in percentages and fractions. Results: Fourteen (4.3%) of the 326 chest trauma patients had TDI with 57.1% from penetrating causes and 42.9% from blunt causes. The causes of the TDI were gunshot injuries (42.9%), road traffic crashes (35.7%), stab injury (14.3%), and domestic accidents (7.1%). The preoperative method of diagnosis was mainly by massive haemothorax necessitating open thoracotomy (42.9%) and mixed clinical evaluation, chest radiograph, and upper gastrointestinal contrast studies (35.7%), and the drainage of intestinal content following the insertion of a chest tube to initially drain haemothorax (21.4%) and other modality of diagnoses (7.1%). The operative finding was mainly intestine content in the chest (50%) and only diaphragmatic injury (35.7%). The major complication after surgery was empyema thoracis (14.3%) and the mortality rate (14.3%). Conclusion: Penetrating injury of the chest was the major factor responsible for the TDI, and even with bowel perforation and acute TDI, thoracotomy offered an effective surgical approach for all the patients.
ABSTRACT
Background: The emergence of COVID-19 had a massive impact on the health system globally. While there are many kinds of literature reporting the impact on postgraduate medical training in other parts of the world, this cannot be said about Nigeria. Methodology: This was a national cross-sectional study among Resident doctors via an online google form survey for 8-months. Stratified cluster design where the entire country was stratified into the six geopolitical zones, and Tertiary Health Institutions (THI) were randomly selected from each of these zones. Data from the 47-item google form were analysed with Statistical Package for Social Science (SPSS) version 23, and internal consistency reliability was measured by Cronbach's alpha coefficient. Categorical variables were compared using chi-square, and the p-value was <0.05. Results: A total of 239 residents from THI in all six geopolitical zones completed the survey. The mean± standard deviation of the age of respondents, years in practice, and years in residency were 36.3±4.4); 10.2±7.6 years, and 4.2±2.6 years, respectively. The Cronbach's alpha coefficient was 0.95. Less than half had delayed the progression of residency (44.4%). The least strongly positive impacts were related to recruitments (4.2%), laboratory testing (4.2%), and ward rounds (4.2%); and the more strongly positive disruptive impact was on postgraduate seminars (9.2%), research (8.4%), professional examinations (8.0%) and residents' clinical schedules (8.0%). Conclusion: COVID-19 has caused a considerable delay in residents' training programs, and resident doctors have great concerns regarding the pandemic. This impact is perceived by them in almost all aspects of the training.
ABSTRACT
Background: The data on the epidemiology of lung cancer in Niger delta states is scarce. Therefore, this study aims to determine the epidemiological profile of lung cancer in two Niger Delta states in Nigeria. Methodology: This was a retrospective analysis of all patients managed for histologically diagnosed lung cancer from Jan 2014 to Dec 2019 at two tertiary hospitals in Niger Delta states of Nigeria. The demographics, diagnoses, results of investigations, and outcomes were analysed using descriptive statistics. Results: Forty-three patients were reviewed with a male-to-female ratio of 1.5:1 and an age range between 13-89 years with a mean of 53.5+17.0 years. The following number of patients; 1(2.3%), 26(60.5%), 4 (9.3%) and 12(27.9%) were distributed according into the following age groups ;< 20, 20-59, 60-64 and >65 respectively. Eleven (25.6%) patients were smokers. The commonest symptoms were dyspnoea in 39(90.7%), cough in 35(81.4%), weight loss in 29(67.4%), chest pain in 28(65.1%), and change in voice (hoarseness of voice) in 8(18.6%); while the signs were respiratory distress in 33(76.7%), digital clubbing in 8(18.6%), superior vena cava syndrome in 2(4.7%).The left lung was commonly affected in 24(55.8%) patients, and the left upper lobe was the most common in 21 (20.2%), while the right upper lobe was the least in 13(12.6%) patients. The histological types were Adenocarcinoma in 26(60.5%), squamous cell carcinoma in 15(34.9%) patients, and small cell carcinoma in 2(4.7%) patients. Fifteen (34.9%) patients had elevated platelets. The modalities of pathologic diagnoses were: Mini-Thoracotomy10 (23.3%), Tru-cut biopsy 28 (65.1%), and Bronchoscopy 5 (11.6%).The mortality rate after six months following lung cancer diagnosis was 7(16.2%). Conclusion: In our environment, lung cancer may have a bimodal distribution, peaking in the middle age group and elderly patients who were mainly non-smokers. Elevation of platelets was observed in a significant number of patients.
