Sleep health of healthcare workers in Kano, Nigeria.

BACKGROUND: The relevance of sleep in the life of a human being cannot be overemphasized in terms of physical and mental well-being. Among several factors that can affect the sleep health of an individual occupation have been found to play a prominent role. The literature is still scanty with regard to sleep studies in our environment. AIM: This study aims to assess the sleep health of tertiary healthcare workers in Kano Nigeria and find, if any, its determining or related factors. MATERIAL AND METHODS: This study was cross-sectional questionnaire-based survey and involved all consenting staff members of Aminu Kano Teaching Hospital, Kano, Nigeria. The Pittsburgh Sleep Quality Index Questionnaire was used to assess the sleep health of the participants. RESULTS: The participants' ages ranged from 18 to 65 years and have a mean age of 38.94 ± 8.07 years. There were 119 (74.4%) males and 41 (25.4%) females with a M:F ratio of 3:1 (χ2 = 19.415; P = 0.000). Among the 155 participants who completed all the aspects of the Pittsburgh Sleep Quality Index questionnaires, the overall sleep quality of the study population was found to be significantly poor [good sleepers = 71 (45.8%), poor sleepers = 84 (54.2%), χ2 = 116.4; P = 0.000]. Considering the various occupational groups working in the hospital, poor sleep was commonest among the nurses 35 (42.7%). Furthermore, among the nurses, poor sleep was significantly commoner in those on shift work 27 (77.1%) than those not on shift work 8 (22.9%); χ2 = 36.2; P = 0.000. Multivariate logistic regression analysis showed that age, sex, and duration in service were not significant predictors of poor sleep quality among the participants [odds ratio (OR) = 1.013, 95% confidence interest (CI) = 0.948-1.084, P = 0.698; OR = 0.691, 95% CI = 0.293-1.631, P = 0.399; and OR = 0.993, 95% CI = 0.932-1.058 P = 0.840, respectively). CONCLUSIONS: Our study found that a significant proportion of healthcare workers and particularly nurses had poor sleep quality. Also, age, sex, and duration in service were not significant predictors of poor sleep quality among the participants.

Indications for tonsillectomy and adenoidectomy: our experience.

BACKGROUND: Infection and obstruction are the most common indications for performing tonsillectomy and adenoidectomy. In the past, infection was the main indication for these procedures; however, in the last few decades obstruction is said to be more prominent as an indication when compared to infection. OBJECTIVE: The objective of this study was to report our observations of indications for tonsillectomy and adenoidectomy. MATERIALS AND METHODS: This is a 2 year retrospective analysis of case records of patients aged 0-18 years who have had tonsillectomy, adenoidectomy and adenotonsillectomy performed in a tertiary hospital. STATISTICAL ANALYSIS USED: IBM SPSS (for windows, version 19) software was used to analyze this data. RESULTS: A total of 115 patient's records were reviewed. Moreover, 33.9% were children under 3 years, 60.0% were between 4 years and 10 years and 6.1% were between the ages of 11 years and 18 years. Obstruction accounted for a total of 68.7% while infection accounted for only 31.3% of the indication for these procedures. CONCLUSION: Obstruction as an indication is proportionally higher in younger children while infection is proportionally higher in older children.

Hearing Results Post Tympanoplasty: Our Experience with Adults at the KKR ENT Hospital, India.

Chronic suppurative otitis media is often associated with some degree of hearing loss. Tympanomastoid surgery is considered effective in controlling infection and preventing recurrence. However, opinions differ with regards the post-operative hearing results. This study aims to assess the hearing results, and also ascertain the effects of some variables on hearing in adult patients with chronic suppurative otitis media after primary tympanoplasty. This was a retrospective review of the clinical records of adult patients with chronic suppurative otitis media, who had primary tympanoplasty at the KKR ENT Hospital and Research Institute in Chennai (India), between 1st June and 30th September, 2011. A total of 26 adult patients with a mean age of 35.85 years (SD 14.775) were studied. There were 16 males (61.54 %) and 10 females (38.46 %). The commonest presenting symptoms were ear discharge (80.8 %) and hearing loss (76.9 %); and the mean duration of symptom was 8.52 years (SD 8.599). The overall mean pre-operative pure tone average was 49.58 dB (SD 18.608), while the overall mean post-operative pure tone average was 37.38 dB (SD 17.837). The difference between the overall mean pre- and post-operative pure tone average (hearing gain) was 12.192 dB (SD 12.924); and this was found to be statistically significant (p < 0.05). Multiple linear regression model showed that only increasing age was significantly associated with increasing mean post-operative pure tone average. This study found primary tympanoplasty effective in improving hearing results in adults with chronic suppurative otitis media even in those with advanced ossicular lesions.

Sensorineural hearing loss in patients with chronic suppurative otitis media.

Even though there are other complications of chronic suppurative otitis media, the aspect of hearing loss is often studied. Nevertheless, the occurrence of sensorineural hearing loss in patients with this disease is still controversial. This study aim (1) to assess the association between sensorineural hearing loss and chronic suppurative otitis media, (2) to investigate some clinical factors that might affect the sensorineural component in patients with this disease. This was a retrospective analysis of the clinical records and pure tone audiograms of patients with chronic suppurative otitis media in a Nigerian Tertiary Health Institution from January 2003 to December 2008. Sixty-nine patients with a mean age of 28.93 years; standard deviation of 18.593 were studied. They had an age range of 4-73 years. The duration of otorrhea ranged from 2 months to 20 years; with a mean of 6.11 years (standard deviation of 6.393). The mean bone conduction threshold in the diseased ear was 39.07 dB (standard deviation of 12.028), and 10.26 dB (standard deviation of 2.620) in the control ear (P < 0.05). The mean bone conduction threshold differences between the diseased and control ears range from 21.69 to 34.52 dB across the frequencies 0.5, 1.0, 2.0, and 4.0 kHz. These differences tended to increase with increasing frequency and were all significant (P < 0.05). In the diseased ears, there were no significant correlation between the age, duration of otorrhea, and the degree of SNHL (r = 0.186, P > 0.05; r = 0.190, P > 0.05 respectively). Patients with chronic suppurative otitis media had a significant degree of sensorineural hearing loss in this study. The higher frequencies were more affected; however, the patient's age and duration of otorrhea seem not to have any correlation with the degree of sensorineural hearing loss.

The role of plain radiographs in the diagnosis of chronic maxillary rhinosinusitis in adults.

BACKGROUND: Computed tomography is currently the gold standard for the diagnosis of chronic rhinosinusitis. However, this facility is not readily available in many developing countries. Thus, plain sinus radiography is still widely in use in our practice. OBJECTIVES: To assess the diagnostic value of plain radiographs in adult patients with uncomplicated chronic maxillary rhinosinusitis. METHODS: This study was carried out at a tertiary health facility in Northern Nigeria. All adult patients with clinical and radiological diagnosis of chronic maxillary rhinosinusitis were included. RESULTS: A total of 88 patients were recruited into the study. There were 51 males (58.0%) and 37 (42.0%) females. Their ages ranged from 18 to 60 years; with a mean age of 31.7±9.20 years. Mucosal thickening was the commonest diagnostic plain radiographic feature, and fluid level was the least. Maxillary antra with diagnostic plain radiographic interpretations of fluid level, haziness and opacity had high specificities (100%, 95.2%, and 85.7%) and high positive predictive values (100%, 75%, and 70%) respectively. CONCLUSIONS: Plain radiographs are relevant in the diagnosis of chronic maxillary rhinosinusitis in our locality only when they show features of fluid level: findings of haziness and opacity are of less diagnostic value.

Plain radiographic evaluation of children with obstructive adenoids.

BACKGROUND: There are several methods of evaluating adenoidal size pre-operatively. Plain nasopharyngeal radiography is a common investigative modality: it has been advocated, and also condemned. AIM: This study was intended to assess nasopharyngeal airway obstruction by the adenoids using plain X-rays; and also to find correlation if any, with the symptomatology. METHODS: This is a retrospective study carried out between January and December 2008. The case notes and plain X-rays of the nasopharynx of 34 paediatric patients with clinical features of obstructive adenoids were analyzed. RESULTS: A total of 34 children were studied, 22 (64.7%) were males and 12 (35.3%) were females. Their ages ranged between 7 months and 10 years: mean age was 3.55 years, standard deviation 2.723. Majority (67.6%) of the children were in the age group 0-4 years. The lowest symptomatology assessment score was 0 and the highest was 3. Children 4 years and below had the highest symptomatology scores. The minimum adenoidal-nasopharyngeal ratio was 0.35 and the maximum was 0.94. There was no significant difference in the mean adenoidal-nasopharyngeal ratio of males and females (t=0.407; p=0.692). Many (75.0%) of the children with moderate to severe nasopharyngeal airway obstruction by the adenoids were in the age bracket 0-4 years. The lowest adenoidal-nasopharyngeal ratio score was 0 and the highest was 3. Children 4 years and below had the highest adenoidal-nasopharyngeal ratio scores. There was a very weak nonsignificant correlation between the symptomatology assessment score and the radiological assessment score (r=0.168; p=0.375). CONCLUSION: The adenoidal-nasopharyngeal ratio is reliable in assessing the nasopharyngeal airway in children with obstructive adenoids.

Plain radiographic evaluation of the nasopharynx: do raters agree?

BACKGROUND: Subjective plain radiographic evaluation of the nasopharynx has been a widely adopted technique. Although it has its own limitations, its ease of interpretation and simplicity are some of its advantages. AIM: To investigate the reliability, using kappa, in subjectively reporting plain nasopharyngeal radiographs in children with symptoms suggestive of enlarged adenoids. METHODS: This was a retrospective study of the clinical records, and plain X-rays of the nasopharynx of paediatric patients with clinical features of adenoid hypertrophy in a Nigerian Tertiary Health Institution from January 2008 to December 2008. RESULTS: Fifty-one children with a mean age of 3.4 years; standard deviation of 2.772 was studied. They had an age range of 2 months to 12 years. Most (66.6%) of the children studied were in the age bracket 0-4 years. The inter-rater reliability between the two Otolaryngologists, and that between an Otolaryngologist and a Radiologist using kappa statistics were 0.6696, 95% CI (0.5035-0.8357; p<0.05) and 0.8182, 95% CI (0.7073-0.9291; p<0.05) respectively. While the kappa intra-rater reliabilities for the two Otolaryngologists were 0.6931, 95% CI (0.5473-0.8389) and 0.9591, 95% CI (0.9033-1.000). CONCLUSION: There was a high level of agreement among trained raters, in subjectively interpreting plain nasopharyngeal radiographs in children with suspected adenoidal obstruction.

Implementing a hospital based injury surveillance system: a case study in Nigeria.

A pilot study of violent injury surveillance was implemented in two hospitals in Kano, Nigeria, in two phases: a formative evaluation including training and arranging the collection of hospital information, followed by a 6 month prospective data collection. Road traffic injuries constituted about 80 per cent of the cases, gunshot injuries were the commonest in victims of interpersonal violence (IPV). The causes and context of IPV, the relationship of victims and perpetrators, and the place, related activities and anatomical site of injuries from IPV are summarized.
