A fatal case of Gradenigo's syndrome in Zimbabwe and the Danish-Zimbabwean ENT collaboration.

As a part of a bilateral educational exchange program two Danish ENT residents were invited to Zimbabwe in 2015. During this exchange a 9-year-old girl was admitted due to complications to acute otitis media (AOM). She developed Gradenigo's syndrome and later on a brain abscess leading to a fatal outcome. Life threatening complications to AOM are rare in developed countries today but are still a challenge in developing countries. We put forward this case from a developing country to bring focus to the fact that a fatal outcome is the consequence if specialist treatment is not accessible.

The introduction of emergency cricothyroidotomy simulation training in Zimbabwe contributed to the saving of two lives.

BACKGROUND: In developing countries with limited access to ENT services, performing emergency cricothyroidotomy in patients with upper airway obstruction may be a life-saving last resort. An established Danish-Zimbabwean collaboration of otorhinolaryngologists enrolled Zimbabwean doctors into a video-guided simulation training programme on emergency cricothyroidotomy. This paper presents the positive effect of this training, illustrated by two case reports. CASE REPORTS: A 56-year-old female presented with upper airway obstruction due to a rapidly progressing infectious swelling of the head and neck progressing to cardiac arrest. Cardiopulmonary resuscitation was initiated and a secure surgical airway was established via an emergency cricothyroidotomy, saving the patient. A 70-year-old male presented with upper airway obstruction secondary to intubation for an elective procedure. When extubated, the patient exhibited severe stridor followed by respiratory arrest. Re-intubation attempts were unsuccessful and emergency cricothyroidotomy was performed to secure the airway, preserving the life of the patient. CONCLUSION: Emergency cricothyroidotomy training should be considered for all surgeons, anaesthetists and, eventually, emergency and recovery room personnel in developing countries. A video-guided simulation training programme on emergency cricothyroidotomy in Zimbabwe proved its value in this regard.

Hearing impairment and deafness among HIV infected children and adolescents in Harare, Zimbabwe.

Background: Among HIV-infected children ear infections are recurrent and chronic, which may lead to hearing loss. Objective: To determine the prevalence, cause and severity of hearing impairment among HIV-infected children aged 5-17 years attending for HIV care in Harare. Design and Setting: An analytical cross-sectional survey conducted at Newlands Clinic, an opportunistic infections clinic in Harare. Materials and Methods: Participants underwent a standardised otoscopic examination of the ear and Pure Tone Audiometry (PTA). Factors associated with hearing impairment were investigated using multivariate logistic regression. Results: Three hundred and eighty (380) participants (55% female and mean age 11 years (SD: 3.3 years)) were consecutively recruited. The vast majority of participants (n=338; 89% were taking antiretroviral therapy (ART) for a median of 3 (IQR: 2-5) years at recruitment, and the most recent median CD4 Count (i.e. CD4 count measured within 6 months of the study recruitment) was 725 (IQR: 497-1000) cells/µL, with no difference by ART status. 61% (n= 231) of participants had an abnormal ear examination. Of the 359 participants who underwent audiometry, the prevalence of hearing impairment was 32.3% (95%CI: 27.5%-37.4%) based on a PTA threshold ≥26Db. Hearing impairment was associated with a recent CD4 count <350cell/µL (OR 2.1, P<0.037). Conclusion: There is a high prevalence of hearing impairment among HIV-infected children and adolescents. Low CD4 count remains a risk factor even among those who are on ART. We recommend that HIV infected children and adolescents, particularly those with low CD4 counts, should have routine evaluation of hearing as part of HIV care.
