Increased Risk of Migraine among Students with Asthma: Results of Headache and Asthma Study among University Students

BACKGROUND

Several studies in developed countries have investigated the relationship between migraine and asthma.

OBJECTIVE

To examine the relationship between asthma and migraine among university students in a low middle-income country.

METHODS

We conducted a cross-sectional study across three universities in the middle belt region of Nigeria. A self-administered questionnaire developed from the International Classification of Headache Disorders was used to screen for migraine. The European Community Respiratory Health Survey (ECRHS) survey tool screened for asthma and its related conditions. Migraine was diagnosed in subjects with recurrent, moderate to severe unilateral throbbing headaches associated with nausea, vomiting, or visual disturbances. Asthma was defined as reporting a previous asthma attack or currently taking asthma medication within the preceding 12 months.

RESULTS

The frequency of asthma was significantly higher among those with migraine than those without migraine (28.6% vs. 9.0%). Conversely, migraine was significantly prevalent in participants with asthma (7.1%vs. 1.9%). On multivariate analysis, there were significant associations between migraine and asthma [aOR = 2.56 (95% CI 1.15-5.77)]. Other factors associated with migraine were female gender [aOR = 2.22 (95% CI 1.06-4.65)] and family history of recurrent headache in firstdegree relatives [aOR = 4.03 (95% CI 1.15-5.77)].

CONCLUSION

Our study shows an increased frequency and risk of migraine in participants diagnosed with asthma and vice versa. These results support the bidirectional association between migraine and asthma. Physicians, therefore, should be aware of the possibility of migraine in patients with asthma who complain of headaches.

Clinicopathological Pattern and Management of Primary Lung Cancer in Ilorin, Nigeria

BACKGROUND

Lung cancer incidence and mortality rates have increased in some low and medium-resourced countries.

OBJECTIVES

This study aimed to describe the clinicopathological pattern and management of lung cancer seen in our setting.

METHODS

We reviewed cases of pulmonary neoplasm diagnosed and managed at the University of Ilorin teaching hospital over eight years. Cases with tissue diagnosis were enrolled in the study and relevant clinical data were collected from the medical record using a proforma.

DESIGN

Hospital-based retrospective study.

RESULTS

Out of the 71 cases of primary lung cancer reviewed, 44(62%) were males and the male to female ratio was 2:1. The mean age was 62±14 years and the occurrence was highest in aged 50-69 years. Thirty (42.3%) with histories of tobacco smoking were males. Adenocarcinoma accounted for 34(54.9%), 23(32.4%) were squamous cell carcinoma, 2(2.8%) were large cell carcinoma and 6(8.5%) were other histological variants. The majority (82.7%) presented at stage III-IV lung cancers, 56.3% had malignant pleural effusion and 74.6% received palliative care. Thirty-eight (53.3%) had chest tube drainage, 19(26.7%) underwent chemical pleurodesis and 22(31.0%) received Cisplatin-based systemic chemotherapy. One patient had curative surgery and none received radiotherapy. At 12 months, 4 (5.6%) were still alive, 14(19.7%) cases had medical records of their death and 53(74.7%) were lost to follow up.

CONCLUSION

This study has highlighted the clinicopathological trend, high rate of mortality and late presentation of lung cancer in our setting. There is a need to increase the awareness of the warning signs and risk factors to ensure early detection and facilitate curative therapy.

Assessment of Post-Treatment Health-Related Quality of Life among Patients with Pulmonary Tuberculosis in Ilorin, Nigeria

BACKGROUND

A lot of attention has generally been given to the microbiology and treatment of pulmonary tuberculosis with relatively limited consideration on its impact on the physical, psychological and social domains of the individual especially after successful drug treatment.

AIM AND OBJECTIVES

This study aimed at assessing the health-related quality of life (HRQoL) and related factors among individuals who had successfully completed treatment for pulmonary tuberculosis (PTB) in Ilorin.

METHODS

This was a hospital based cross-sectional study at the pulmonary outpatient clinics of the University of Ilorin Teaching Hospital and Kwara State Specialist Hospital, Sobi, Ilorin. HRQoL assessment was conducted in 308 consenting patients who had been certified microbiologically cured for bacteriologically confirmed PTB in the preceding three years using the validated St. George's Respiratory Questionnaire (SGRQ). All subjects also had plain chest radiograph done for assessment of the presence and extent of lung parenchymal damage.

RESULTS

The overall total median percentage HRQoL score was 18.5 (7.9-28.2) with the highest score in the activity component [33.7 (18.3-41.8)] and least scores in the impact component [10.0 (0.0-21.9)]. The independent predictors of impaired HRQoL were age > 40 years (p= 0.007), absence of formal education (p=0.004), mMRC score >1 (p= 0.002), PTB retreatment (p=<0.001) and radiographic scores >3 (p= <0.001).

CONCLUSION

There is impaired HRQoL following treatment for PTB in Ilorin. Hence, there is a need to incorporate HRQOL assessment as an adjunct outcome measure after PTB treatment especially in those with the above identified risk factors.

Acute Oxygen Therapy on Hospital Wards in Low Middle-Income Country: Experience from a Referral Centre in Ilorin, Nigeria

BACKGROUND

Oxygen is like any other medication that can cause severe consequences if administered inappropriately.

OBJECTIVE

To audit the pattern of acute oxygen therapy on regular hospital wards of a referral centre in Ilorin, Nigeria.

METHODS

We reviewed 150 patients that received or had a prescription for acute oxygen therapy in three months and extracted relevant information using a proforma.

RESULTS

About one-third of the patients (30%) were >65 years of age and the male to female ratio was 1:1. The commonest indication and medical condition for acute oxygen administration were hypoxemia (70.7%) and pneumonia (26.0%), respectively. Pneumonia accounted for most (41.2 %) of the oxygen therapy in childhood. The majority of patients (88.0%) had written order for oxygen prescription, 40.7% had a prescription to target oxygen saturation and only 31.3% achieved their target saturation. Oxygen prescription was adequate (documentation of delivery device, flow rate of oxygen, and target oxygen saturations) in 40.7% of patients. The assessment, monitoring and titration of oxygen therapy were adequate in 92.7%, 65.3% and 28 % of patients respectively. Overall mortality was 27.3% in patients receiving acute oxygen supplementation. Eleven patients had unstable COPD, and 63.6 %, 54.5 % and 45.6 % of them had adequate oxygen prescription, monitoring and titration respectively. The challenges to oxygen use were faulty delivery devices, emptied oxygen cylinders, inability to routinely do arterial blood gas analysis and lack of hospital oxygen protocol.

CONCLUSION

The current practice of acute oxygen therapy is not satisfactory and interventions are advocated to improve the healthcare providers' administration of oxygen.

Profile of patients with chronic obstructive pulmonary disease in Ilorin who were never-smokers

Background

The most recognized risk factor for chronic obstructive pulmonary disease (COPD) worldwide is cigarette smoking. However, recent surveys have revealed an increasing trend from nonsmoking causes especially from biomass exposure. This study, therefore, aimed to determine the proportion of patients and the clinical pattern of COPD among never-smokers in Ilorin.

Subjects and Methods

This is a retrospective study in which case records of patients with clinical diagnosis of COPD from January 2013 to December 2017 were reviewed. Data were collected with respect to their sociodemographic characteristics, clinical details, comorbid illnesses, and severity of the disease.

Results

A total of 135 case records of patients with COPD were reviewed, of which 66 had spirometric confirmation of the disease. In all, 38 (57.6%) of them were never-smokers with a male-to-female ratio of 1:1.1. The mean age of the subjects was 64.5 ± 11.7 years. Cough and exertional dyspnea were the most common symptoms (89.5% each), and systemic hypertension was the most common comorbid illness. Firewood exposure constituted the most common nonsmoking risk factor (47.4%), and the majority of the patients had mild COPD. When compared with ever-smokers, the mean post bronchodilator lung function parameters were found to be significantly better in never-smokers.

Conclusion

Over half of COPD cases in Ilorin were never-smokers with firewood exposure as the main risk factor. This study has further highlighted the need for increased awareness of the hazards of biomass fuel exposure in our setting.

Lung cancer awareness and anticipated delay before seeking medical help in the middle-belt population of Nigeria

SETTING

Ilorin metropolis in the middle-belt region of Nigeria.

OBJECTIVES

To determine the awareness about warning signs and risk factors for lung cancer and the anticipated delay before seeking medical care in the middle-belt population of Nigeria.

DESIGN

This was a cross-sectional study performed among 1125 adults. Lung cancer awareness measure (Lung CAM) was administered face to face by trained interviewers.

RESULTS

The respondents' Lung CAM score was low for warning signs and risk factors for lung cancer. Apart from tobacco smoking (69.9%) and air pollution (56.4%), other risk factors were poorly recognised by respondents. Higher education and income and having a relative or friends who had previously had lung cancer were significantly associated with awareness about warning signs and risk factors. The majority (66.8%) would seek help before 2 weeks if they noticed a warning sign. Anticipated delay was associated with non-recognition of any warning sign (OR 3.09, 95%CI 2.26-4.22), lower education (OR 1.90, 95%CI 1.40-2.57), lower income (OR 1.86, 95%CI 1.26-2.75) and males (OR 1.50, 95%CI 1.15-1.97).

CONCLUSION

The awareness of lung cancer warning signs and risk factors are not satisfactory in Nigeria. There is a need to increase awareness about the condition to prevent delays in seeking medical help.
