Hearing disorder in HIV positive adult patients not on Anti - Retroviral drugs at Kenyatta National Hospital
Objectives: To determine the prevalence and type of hearing disorders in HIV positive patients not on anti - retroviral drugs (ARVs) and correlate this with the world health Organization (WHO) stage of HIV disease and CD4 positive cell counts.Design: Case control study.Setting: comprehensive care clinic (CCC) and voluntary counseling and testing centre at Kenyatta National Hospital.Subjects: One hundread and ninety four HIV positive patients attending CCC and 124 HIV negative subjects recruited from voluntary counseling and testing (VCT) centre.Results: Hearing loss (HL) was present in 33.5% of HIV positive compared to 8.1% in negative subjects. No gender bias in HL Sensorineural hearing loss (SNHL) was the most common and the frequencies most ‘affected were four and eight kHzConclusion: Hearing loss is more prevalent in HIV positive individuals not on anti - retroviral drugs than negative normal subjects. Low CD4 cell count and advanced HIV diseases were associated with increased chance of having a hearing loss. Otological care should be part of the comprehensive care of HIV positive patients
Hearing Disorders in HIV Positive Adult Patients
Background: This study was aimed at determining the prevalence and type of hearing disorders in HIV positive patients and any correlationship with the CD4 counts/stage of HIV/AIDS in patients attending the comprehensive care clinic (CCC).Methods: Case control study of 194 HIV positive patients attending CCC recruited into the study after informed consent. A thorough clinical examination and otoscopy done followed by tuning fork tests, Pure Tone Audiometry and tympanometric tests. This was compared with 124 HIV negative subjects matched for age and sex who were recruited from the voluntary counseling and testing centre. The world health organization staging of the HIV/AIDS disease and the CD4 positive lymphocyte cell count were carried out and correlated with any hearing disorder. Results were analyzed using statistical package for social sciences version 10.0.Results: Hearing loss (HL) was present in 33.5% of HIV positive compared to 8.1% in negative subjects. No gender bias in HL but HL worsened with advancement of age. SNHL was the most common and the higher frequencies were the most affected. Low CD4 cell count and advanced HIV disease were associated with increased chance of having a hearing loss.Conclusion: Hearing loss is more prevalent in HIV positive individuals than negative normal subjects and tends to worsen with the advancement of the HIV disease. This may negatively impact on the overall care and standard of living of HIV positive patients, hence otological care should be part of the comprehensive care
Bronchoscopy for Removal of Aspirated Tracheobronchial Foreign Bodies at Kenyatta National Hospital, in Kenya
Background: This study was aimed at defining the presentation, morbidity and mortality following inhalation and subsequent removal of tracheobronchial foreign body using a rigid bronchoscope.Methods: This was a retrospective, cross-sectional study undertaken in the Ear Nose and Throat-Head and Neck Surgery Unit of Kenyatta National Hospital. The study population consisted of patients with brochoscopically proven tracheobronchial foreign body. Case notes of 107 consecutive admissions with brochoscopically verified tracheobronchial foreign bodieswere analyzed for age, sex, time interval between inhalation and removal, duration of stay in hospital, complications and mortality.Results: The vast majority of patients were below 3 years of age and 63% of them presented within 3 days after onset of symptoms. The right bronchus was the most frequent destination of inhaled foreign bodies (50.5%) followed by the left bronchus (17.8%) and carina (14.2%) inthat order. The turnover of patients with inhaled foreign bodies was high with 86.9% being discharged within 6 days after surgery. The bronchoscopic procedure was uneventful in 76.6% of patients. Repeat bronchoscopy was performed in three patients with one undergoing eventual thoracotomy.Intraoperative cardiac arrest occurred in 5 cases (4.6%) with successful resuscitation in 2 and mortality in three (2.7%) % cases.Conclusion: Bronchoscopic removal of inhaled foreign bodies remains one of the riskiest otolaryngologic emergencies in Kenyatta National Hospital partly because of involvement of the life sustaining airway and partly because of lack of ideal equipment and adequate expertise. The need for hands on experience and close cooperation and familiarity between theanaesthesiologist and the bonchoscopist is emphasized
Fatal Injuries in the Slums of Nairobi and their Risk Factors: Results from a Matched Case-Control Study
Injuries contribute significantly to the rising morbidity and mortality attributable to non-communicable diseases in the developing world. Unfortunately, active injury surveillance is lacking in many developing countries, including Kenya. This study aims to describe and identify causes of and risk factors for fatal injuries in two slums in Nairobi city using a demographic surveillance system framework. The causes of death are determined using verbal autopsies. We used a nested case-control study design with all deaths from injuries between 2003 and 2005 as cases. Two controls were randomly selected from the non-injury deaths over the same period and individually matched to each case on age and sex. We used conditional logistic regression modeling to identity individual- and community-level factors associated with fatal injuries. Intentional injuries accounted for about 51% and unintentional injuries accounted for 49% of all injuries. Homicides accounted for 91% of intentional injuries and 47% of all injury-related deaths. Firearms (23%) and road traffic crashes (22%) were the leading single causes of deaths due to injuries. About 15% of injuries were due to substance intoxication, particularly alcohol, which in this community comes from illicit brews and is at times contaminated with methanol. Results suggest that in the pervasively unsafe and insecure environment that characterizes the urban slums, ethnicity, residence, and area level factors contribute significantly to the risk of injury-related mortality
Hereditary haemorrhagic telangiectasia in a black adult male: case report
Hereditary haemorrhagic telangiectasia, (HHT) or Rendu-Osler-Weber disease is a genetic autosomal dominant disorder that is characterised by telangiectasias, (small vascular malformations), in mucocutaneous tissues and arterial venous malformations, (AVMs), in various internal organs. Although HHT is relatively common in whites, the disorder has been reported to be rare in people of black African descent. Majority of HHT patients present with recurrent epistaxis, which in a significant proportion of patients is severe, warranting repeated blood transfusions and iron supplementation. Telangiectasias are most frequent on the tongue, hands, nose, lips and the gastrointestinal tract (GIT). AVMs occur in internal organs, particularly the lungs, brain, and the liver. Early and correct diagnosis of HHT is crucial as patients derive benefit from certain specific treatment modalities. Besides, AVMs which occur in various organs pose serious complications
that may lead to death and therefore require early detection. We report a 55 year old black African male with HHT who presented with severe recurrent epistaxis and haematochezia leading to severe anaemia requiring repeated blood transfusions. His son, daughter and a maternal uncle experience milder recurrent epistaxis. The management of this patient and a brief review of the clinical features and management of HHT is presented. Our aim is to raise awareness of the occurrence of HHT in Kenya, in order to enhance early diagnosis and appropriate management.East African Medical Journal Vol. 85 (8) 2008: pp. 412-41

Avaliação da sintomatologia pré e pós-operatória de pacientes submetidos à turbinectomia inferior Assessment of pre and postoperative symptomatology in patients undergoing inferior turbinectomy
A turbinectomia parcial inferior é um procedimento comumente realizado para tratamento da obstrução nasal secundária à rinite hipertrófica e não-responsiva a tratamento clínico. O presente trabalho procura avaliar o impacto desse tipo de procedimento na qualidade de vida dos pacientes, analisando a melhora dos sintomas de obstrução nasal, coriza, crises esternutatórias e prurido nasal após seis meses do procedimento cirúrgico. FORMA DE ESTUDO: clínico prospectico. MATERIAL E MÉTODO: Quarenta e nove pacientes submetidos à turbinectomia parcial inferior associada ou não à septoplastia receberam questionários onde graduavam a intensidade dos sintomas supracitados. Por meio da comparação entre a intensidade dos sintomas no pré-operatório e os seis meses após a cirurgia foi possível avaliar o grau de melhora de cada sintoma. O resultado foi, então, classificado em nulo, bom, regular e ótimo, na dependência da subtração do escore após seis meses de cirurgia pelo escore pré-operatório. RESULTADOS: A obstrução nasal apresentou resultado bom ou ótimo em 98% dos pacientes. Quanto à coriza, a cirurgia teve resultado bom ou ótimo em 49% dos casos. As crises esternutatórias apresentaram estes resultados em 81,6% e, com relação ao prurido nasal, 45% dos pacientes obtiveram este índice de melhora. CONCLUSÃO: Esse estudo mostra que os benefícios clínicos obtidos com a turbinectomia parcial inferior não se limitam a melhora da obstrução nasal, estendendo-se também a outros sintomas da rinopatia alérgica, notadamente no que se refere às crises esternutatórias.<br>Partial inferior turbinectomy is a procedure directed to treat nasal obstruction secondary to hypertrophy rhinitis. This study evaluates the impact of this procedure in the quality of life of the patients, analyzing the improvement of other symptoms such as rhinorrhea, nasal itching and sneezing after six months of the surgical procedure. STUDY DESIGN: clinical prospective. MATERIAL AND METHOD: Forty-nine patients submitted to turbinectomy associated or not with septoplasty, received questionnaires to grade the intensity of symptoms. Through the comparison of severity of symptoms before and after six months of the surgery, it was possible to evaluate the degree of improvement of each symptom. The results were classified as null, good, moderate and great, and we subtracted postoperative score from the preoperative score. RESULTS: The nasal obstruction presented good or great results in 98% of the patients. For rhinorrhea, the surgery has resulted in good or great improvement in 49% of the cases. Sneezing presented good or great results in 81.6% of the patients and, nasal itching, 45%. CONCLUSION: The study showed that the clinical benefits obtained with the partial inferior turbinectomy are not limited to nasal obstruction, extending also to others symptoms of rhinitis, mainly in relation to sneezing crisis
