Hearing impairment in Angolan children with acute bacterial meningitis with and without otitis media.

AIM: Bacterial meningitis (BM) is a common cause of hearing loss in childhood. Our aim was to investigate bacterial aetiology, hearing impairment and outcome in childhood BM with vs. without otitis media (OM) in Angola. METHODS: Hearing was tested by auditory brainstem response in 391 (76%) children with confirmed BM. The bacteria identified from the ear discharge were compared to those from cerebrospinal fluid (CSF). The hearing findings were compared among children with vs. without OM on days 1 and 7 of hospitalization, and at follow-ups of 1, 3 and 6 month(s). RESULTS: No correlation was found in bacteriology between the ear discharge and CSF. On day 7 in hospital, hearing impairment (>40 dB) was common, regardless of whether concomitant OM or not (in 27% vs. 30%, respectively). Any hearing deficit on day 7 was associated with a higher risk of complicated or fatal clinical course (OR 2.76, CI95% 1.43-5.29, p = 0.002). CONCLUSION: No significant difference prevailed in hearing thresholds between children with or without OM in hospital on day 7 or at later follow-ups. Any hearing impairment during hospital stay associated with a higher risk for complicated clinical course or death.

Ramsay Hunt syndrome: long-term facial palsy outcome assessed face-to-face by three different grading scales and compared to patient self-assessment.

PURPOSE: To determine the long-term facial palsy outcome of Ramsay Hunt Syndrome by face-to-face grading by House-Brackmann Grading System, Facial Nerve Grading System 2.0, and Sunnybrook Facial Grading System concomitantly. To compare the applicability of the grading scales. To compare patients' self-assessed facial palsy outcome results to gradings performed by the investigator. To compare the face-to-face assessed facial palsy outcome to the initial palsy grade. METHODS: Fifty-seven patients self-assessed their facial palsy outcome and came to a one-time follow-up visit. The palsy outcome was graded by one investigator using the three above-mentioned grading systems concomitantly. The median time from syndrome onset to follow-up visit was 6.6 years. RESULT: A good long-term face-to-face assessed palsy outcome was enjoyed by 84% of the patients. Trying to assess only one House-Brackmann grade to represent the palsy outcome was impossible for most patients. Facial Nerve Grading System 2.0 worked better, but needed adjustments and certain sequelae findings needed to be neglected for it to be executable. The Sunnybrook system worked the best. Nearly 20% of the patients assessed themselves differently from the investigator: both better and worse. CONCLUSION: The Sunnybrook scale was the most applicable system used. With antiviral medication, the outcome of facial palsy in Ramsay Hunt syndrome starts to resemble that of Bell's palsy and emphasizes the importance of recognizing the syndrome and treating it accordingly. The results give hope to patients instead of the gloomy prospects that have stigmatized the syndrome.

Facial palsy in children: long-term outcome assessed face-to-face and follow-up revealing high recurrence rate.

PURPOSE: To evaluate the long-term (minimum of 2 years from the palsy onset) outcome of pediatric facial palsy by patient questionnaire and face-to-face assessment by the Sunnybrook facial grading system, House-Brackmann grading system, and Facial Nerve Grading System 2.0. To compare the outcome results of self-assessment with the face-to-face assessment. To assess the applicability of the grading scales. To assess the palsy recurrence rate (minimum of a 10-year follow-up). METHODS: 46 consecutive pediatric facial palsy patients: 38 (83%) answered the questionnaire and 25 (54%) attended a follow-up visit. Chart review of 43 (93%) after a minimum of 10 years for the facial palsy recurrence rate assessment. RESULTS: Of the 25 patients assessed face-to-face, 68% had totally recovered but 35% of them additionally stated subjective sequelae in a self-assessment questionnaire. Good recovery was experienced by 80% of the patients. In a 10-year follow-up, 14% had experienced palsy recurrence, only one with a known cause. Sunnybrook was easy and logical to use, whereas House-Brackmann and the Facial Nerve Grading System 2.0 were incoherent. CONCLUSIONS: Facial palsy in children does not heal as well as traditionally claimed if meticulously assessed face-to-face. Patients widely suffer from subjective sequelae affecting their quality of life. Palsy recurrence was high, much higher than previously reported even considering the whole lifetime. Of these three grading systems, Sunnybrook was the most applicable.

Ramsay Hunt syndrome: characteristics and patient self-assessed long-term facial palsy outcome.

PURPOSE: To explore the characteristics, medical treatments, and long-term facial palsy outcome in Ramsay Hunt syndrome. METHODS: Patient questionnaire including self-assessment of long-term facial palsy outcome and retrospective chart review. Initial facial palsy grade was compared to self-assessed or patient record stated palsy outcome. Occurrence of different characteristics (blisters, hearing loss, vertigo, etc.) of the syndrome were assessed. RESULTS: Altogether 120 patients were included of which 81 answered the questionnaire. All but one patient had received virus medication (aciclovir, valaciclovir), and half received simultaneous corticosteroids. If the medication was started within 72 h of Ramsay Hunt diagnosis, facial palsy recovered totally or with only slight sequelae in over 80% of the patients. Only a minority of the patients experienced varicella blisters simultaneously with facial palsy, blisters more often preceded or followed the palsy. Approximately 20% of the patients had their blisters in hidden places in the ear canal or mouth. CONCLUSIONS: The long-term outcome of facial palsy in medically treated Ramsay Hunt syndrome was approaching the outcome of Bell's palsy. It is crucial to ask and inform the patient about the blisters and look for them since, more often than not, the blisters precede or follow the palsy and can be in areas not easily seen.

Oral and Otorhinolaryngological Findings in Adults Who Were Diagnosed With Pediatric Onset Crohn's Disease: A Controlled Study.

BACKGROUND: Up to 50% of pediatric patients with Crohn's disease (CD) report oral manifestations, but less is known about their oral health when they become adults. GOALS: Our aim was to provide detailed descriptions of the presence of oral and otorhinolaryngological manifestations in patients with pediatric onset CD once they reached adulthood, to look for predisposing factors and to compare the findings to matched controls. STUDY: Adult patients diagnosed with CD in childhood at the Children's Hospital, University of Helsinki, Finland, after 2000 were invited for a follow-up appointment in 2016 and 24 were examined by a dentist and otorhinolaryngologist. They were compared with 22 matched controls from the Population Register Centre. The participants completed questionnaires about their general health, any special diets, and their health-related quality of life. Their nutrition was evaluated from food records. RESULTS: Patients with CD had minor oral manifestations at a median of 9 years after their childhood diagnosis and the most common was angular cheilitis, which affected 6 patients and 1 control, but was not statistically significant (P=0.0984). CD with perianal abscessing disease correlated to orofacial findings (P=0.0312). Most of the patients had normal otorhinolaryngological findings. Subjects with oral lesions had lower mean health-related quality of life scores than subjects without oral findings and the differences were clinically but not statistically significant. Oral manifestations were not associated with differences in energy intake. CONCLUSIONS: Oral manifestations in adult patients with pediatric onset CD were mild and were not associated with otorhinolaryngological pathology.

Detailed Follow-up Study of Pediatric Orofacial Granulomatosis Patients.

OBJECTIVES: Orofacial granulomatosis (OFG) is a chronic inflammatory condition affecting the orofacial area. Its connection to Crohn disease (CD) is debated. Our aim was to describe a cohort of pediatric patients with OFG in detail, study the long-term behavior of OFG, and evaluate factors predicting CD in patients with OFG. METHODS: We invited patients diagnosed with OFG at 2 university hospitals, Finland for a follow-up appointment. Patients (n = 29) were examined by a dentist and an otorhinolaryngologist using a structural schema. Orofacial findings were also recorded using digital photographing. Patients filled in questionnaires about general health and special diets. Patients' nutrition was evaluated from food records. The findings were compared between patients with OFG only and OFG with CD. RESULTS: Patients with CD had more findings in the orofacial area (total score for orofacial findings median 11) compared to patients with OFG only (total score median 7.5). There was no statistically significant difference in the type of lesions between these groups, except the upper lip was more often affected in patients with CD (n = 11) than in patients with OFG only (n = 0). Most of the patients had normal otorhinolaryngological findings. All patients with elevated anti-Saccharomyces cerevisiae antibody A levels had CD (n = 6) and they presented with more orofacial findings (total score) than patients with normal levels of anti-S cerevisiae antibody A (P = 0.0311). CONCLUSIONS: Long-term follow-up of pediatric-onset patients with OFG shows good prognosis. Patients with OFG do not seem to have otorhinolaryngological comorbidity. Anti-S cerevisiae antibody A may serve as a factor to indicate the possible presence of underlying CD in patients with OFG, but further studies are requested.

Metronidazole in conjunction with penicillin neither prevents recurrence nor enhances recovery from peritonsillar abscess when compared with penicillin alone: a prospective, double-blind, randomized, placebo-controlled trial.

OBJECTIVES: The objectives of this study were to evaluate the efficacy of metronidazole in conjunction with penicillin in preventing the recurrence of peritonsillar abscess (PTA) and to learn whether metronidazole enhances the recovery from PTA when compared with penicillin alone. METHODS: In this prospective, double-blind, randomized, placebo-controlled trial, 200 adult outpatients with PTA at our ear, nose and throat emergency department received either penicillin (1 000 000IU) × 3 and metronidazole (400 mg) × 3 for 10 and 7 days orally (combination group, N = 100) or penicillin and placebo (penicillin group, N = 100) after incision and drainage of the PTA. Afterwards they received a symptom questionnaire via e-mail daily for 2 weeks, then weekly for 6 weeks. The primary outcome was efficacy of metronidazole in conjunction with penicillin in preventing PTA recurrence in 56 days; the secondary outcome was ability of metronidazole plus penicillin to enhance recovery from PTA in 28 days. All healthcare contacts were registered during follow-up. Registered on www.clinicaltrials.gov with the identifier NCT01255670. RESULTS: Of the 200 patients, 20 returned to hospital with recurrent symptoms, 10 in each group (P = 1.00). In the combination group, the mean (SD) duration of throat-related symptoms was 5.6 (5.0) days and in the penicillin group it was 5.3 (2.7) days, values for fever were 1.5 (0.9) and 1.6 (1.0) days, respectively, and those for poor overall physical condition were 4.0 (3.9) and 4.5 (4.9) days; there were no significant differences between groups. The adverse effects nausea and diarrhoea lasted longer in the combination group (P = 0.01). CONCLUSIONS: For healthy adult PTA patients treated with incision and drainage, metronidazole neither prevents recurrence nor enhances recovery when combined with penicillin compared with penicillin alone, but instead leads to increased adverse effects.

Risk factors and morbidity of infantile haemangioma: preterm birth promotes ulceration.

AIM: We identified the characteristics of an infantile haemangioma (IH) that predispose children to complications, interventions and long-term morbidity and examined perinatal risk factors for IH. METHODS: We studied children with IHs admitted to Helsinki University Hospital's paediatric vascular anomaly clinic in Finland in 2004-2007 and registered perinatal records, IH characteristics, complications and interventions. These patients received a questionnaire on perinatal data and long-term morbidity resulting from IH. We analysed factors related to complications, interventions and morbidity and compared our cohort's perinatal data to the Finnish Medical Birth Register (FMBR) figures. RESULTS: We approached 185 families, of which 136 replied to the questionnaire. Children with facial, segmental and indeterminate IHs showed more complications, interventions and higher long-term morbidity. Preterm birth predisposed infants to ulceration of IHs, with a 95% confidence interval (CI) of 1.02-5.14 and odds ratio (OR) of 2.29. In addition to earlier known risks, maternal gestational diabetes mellitus rate was higher in our IH cohort than the rate in the FMBR (95% CI 1.39-4.95, OR 2.62). CONCLUSION: Physicians treating IHs should consider the elevated ulceration risk in preterm infants. The association between gestational diabetes mellitus and child's risk for an IH is uncertain and requires further research.

Complications of sclerotherapy for 75 head and neck venous malformations.

Sclerotherapy is one treatment option for head and neck venous malformations (VMs). Evaluation of complication risks is, however, essential to improve its safety. We aimed to systematically report sclerotherapy complications by means of the Clavien-Dindo classification and to distinguish factors predisposing to complications. We identified our institution's head and neck VM patients who received sclerotherapy between 1 January 2007 and 31 August 2013, analyzed patient reports retrospectively, and applied to them the Clavien-Dindo classification. Our 75 VM patients underwent a total of 150 sclerotherapy sessions. The most common sclerosants were 3 % sodium tetradecyl sulfate and polidocanol. Complications occurred in 13 patients (17.3 %) and in 15 sessions (10.0 %); 3 complications required extensive postprocedural treatment and caused permanent morbidity, whereas 12 received conservative treatment. Patients with sclerotherapy complications underwent more treatments (p = 0.009) and more often needed further surgery (p = 0.007). We thus consider sclerotherapy a relatively safe treatment modality for head and neck VMs. To avoid complications, evaluation of VM characteristics and optimal treatment technique in a multidisciplinary team is vital.

An interdisciplinary specialist team leads to improved diagnostics and treatment for paediatric patients with vascular anomalies.

AIM: Patients with vascular anomalies are often misdiagnosed, leading to delayed or improper treatment. The aim of this study was to evaluate the impact of an interdisciplinary team on the diagnosis and treatment of paediatric patients with vascular anomalies. METHODS: We reviewed the paediatric patients evaluated by our interdisciplinary team between 2002 and 2012, analysing the referral diagnosis, final diagnosis, patient age, sex, clinical history, laboratory tests, imaging studies and treatments. RESULTS: Of the 480 patients who were evaluated, 435 (90.6%) had a vascular anomaly: 30.7% of all patients had a tumour and 55.2% had a malformation. Haemangiomas comprised 93.2% of all tumours, while malformations included capillary (9.8%), lymphatic (30.1%), venous (36.8%), arteriovenous (3.8%) and combined slow-flow (7.9%) malformations. Tumours were initially diagnosed correctly in 89.2% of the patients, but only 38.0% of the malformations were diagnosed correctly. Improper treatment was given to 1.4%, due to incorrect diagnoses. CONCLUSION: This study showed that haemangiomas were likely to be diagnosed correctly, but other tumours and vascular malformations were likely to be misdiagnosed. Misdiagnosis seldom led to improper treatment, but probably led to delayed treatment in many cases. The interdisciplinary approach led to improved diagnostics and treatment.

[Medical intern or locum doctor--does job position affect learning?]. / Amanuenssi vai viransijainen--vaikuttaako työsuhde oppimiseen?

At the University of Helsinki, the licentiate degree in medicine involves internships that can be conducted as a medical intern or locum doctor. The students and their supervisors fill out a feedback form, which helps in assessing the students' improvement in various areas. Based on the feedback form between 2008 and 2013, students having worked as locum doctor rated better improvement in their diagnostic skills, writing medical records, interacting with the patient, and operating in the work community. Supervisor evaluations did not show a similar clear difference between the job positions.

Vaccine-induced waning of Haemophilus influenzae empyema and meningitis, Angola.

In Angola during 2003-2012, we detected Haemophilus influenzae in 18% of 2,634 and 26% of 2,996 bacteriologically positive pleural or cerebrospinal fluid samples, respectively, from children. After vaccination launch in 2006, H. influenzae empyema declined by 83% and meningitis by 86%. Severe H. influenzae pneumonia and meningitis are preventable by vaccination.

Neuropilin-2 and vascular endothelial growth factor receptor-3 are up-regulated in human vascular malformations.

Despite multiple previous studies in the field of vascular anomalies, the mechanism(s) leading to their development, progression and maintenance has remained unclear. In this study, we have characterized the expression levels of vascular endothelial growth factors and their receptors in 33 human vascular anomalies. Analysis with quantitative real-time PCR and gene-specific assays showed higher expression of neuropilin-2 (NRP2) and VEGF-receptor-3 (VEGFR-3) mRNAs in vascular malformations (VascM) as compared to infantile hemangiomas (Hem). In addition, the expression levels of PlGF and VEGF-C mRNA were significantly higher in venous VascM when compared to the other VascM and Hem. Higher expression of NRP2 and VEGFR-3 were confirmed by immunohistochemistry. To further study the importance of NRP2 and VEGFR-3, endothelial cell (EC) cultures were established from vascular anomalies. It was found that NRP2 and VEGFR-3 mRNA levels were significantly higher in some of the VascM ECs as compared to human umbilical vein ECs which were used as control cells in the study. Furthermore, adenoviral delivery of soluble decoy NRP2 prevented the proliferation of ECs isolated from most of the vascular anomalies. Our findings suggest that NRP2 functions as a factor maintaining the pathological vascular network in these anomalies. Thus, NRP2 could become a potential therapeutic target for the diagnosis and treatment of vascular anomalies.

The use of the probiotic Lactobacillus rhamnosus GG and viral findings in the nasopharynx of children attending day care.

Limited data are available on the effects of probiotics on the nasopharyngeal presence of respiratory viruses in children attending day care. In this substudy of a randomized, double-blinded, placebo-controlled 28-week intervention study, nasopharyngeal swab samples were collected, on visits to a physician due to symptoms of infection, from children receiving control milk (N = 97) and children receiving the same milk supplemented with probiotic Lactobacillus rhamnosus GG (N = 97). The presence of 14 respiratory viruses was assessed by PCR methods, and viral findings were compared with symptom prevalences in the intervention groups. Rhinovirus was identified in 28.6% of 315 swab samples, followed by respiratory syncytial virus (12.4%), parainfluenza virus 1 (12.1%), enterovirus (8.9%), influenza A(H1N1)pdm09 (7.9%), human bocavirus 1 (3.8%), parainfluenza virus 2 (3.2%), adenovirus (2.9%), and influenza A(H3N2) (0.6%). The children in the probiotic group had less days with respiratory symptoms per month than the children in the control group (6.48 [95% CI 6.28-6.68] vs. 7.19 [95% CI 6.98-7.41], P < 0.001). Probiotic intervention did not reduce significantly the occurrence of the examined respiratory viruses, or have an effect on the number of respiratory symptoms observed at the time of a viral finding. Rhinovirus, respiratory syncytial virus, and parainfluenza virus 1 were the most common respiratory viruses in symptomatic children. Children receiving Lactobacillus rhamnosus GG had fewer days with respiratory symptoms than children in the control group, although probiotic intervention was not effective in reducing the amount of viral findings or the respiratory symptoms associated with viral findings.

Recovery of probiotic Lactobacillus rhamnosus GG in tonsil tissue after oral administration: randomised, placebo-controlled, double-blind clinical trial.

The present randomised, double-blind, placebo-controlled study was conducted to determine whether consumption of probiotic Lactobacillus rhamnosus GG (GG) would lead to the recovery of GG in tonsil tissue. After 3 weeks' daily consumption of GG as a single strain (n 20), GG as a part of a multispecies combination (n 17) or placebo (n 20), tonsil tissue samples were collected from fifty-seven young adults during tonsillectomy due to chronic or recurrent tonsillitis. Strain-specific real-time PCR was used to detect GG in the tonsil tissue. GG was recovered in the tonsil sample of 40% of the subjects in the GG group, 41% in the multispecies group and 30% in the placebo group (P value between groups 0.79). In all subjects with positive recovery of GG in the tonsil tissue, GG was also recovered in the faecal sample taken at the start of the intervention and at the time of the tissue sample collection, which indicates more persistent adherence of the probiotic. To conclude, GG can be recovered from tonsil tissue after oral administration as a singlestrain probiotic or as a part of a multispecies probiotic combination. The present results suggest that individual variation exists in the ability of GG to adhere to tonsil tissue. Persistence of GG appears to be high in tonsil tissue as well, in addition to persistence in faecal samples, which has been demonstrated previously. Further clinical trials are warranted to evaluate whether probiotic adherence in the tonsil tissue could have a role in respiratory symptom prevalence.

The clinical picture of juvenile parotitis in a prospective setup.

AIM: To characterize the features of juvenile parotitis in a prospective setup and epidemiology. METHODS: All children with parotitis admitted to Helsinki University Central Hospital 2005-2010 were recruited. Clinical characteristics, given treatment, outcome, blood leukocyte count, C-reactive protein, serum amylase and trypsinogen, SPINK-1 genotype and mumps antibodies were recorded. To map the epidemiology, a questionnaire was sent to 1000 randomly selected 13-year-old children. RESULTS: The prospective study included 41 children (aged ≤ 17) with acute parotitis, all in good general condition. Serum amylase, but not trypsinogen, was elevated in majority of the cases (79%) and C-reactive protein in 68%. Eleven (27%) children had an elevated blood leukocyte count. None had acute mumps. Most children recovered well, 51% being treated symptomatically only. Seven children were treated on ward. Seventeen (46%) children had recurrent symptoms. One child (2.4%) had SPINK P55S mutation. According to the epidemiological questionnaire, 1.1% of the respondents (8/728, response rate 73%) reported a verified episode(s) of parotitis. CONCLUSION: Juvenile parotitis has a frequency close to 1%. In the majority, the general condition is good during the episode. Serum amylase serves as an additional marker for the disease. Parotitis has a tendency to recur in almost half of the cases.

Picornaviruses in cerebrospinal fluid of children with meningitis in Luanda, Angola.

Human enteroviruses are the most common cause of viral meningitis. Viral-bacterial interaction may affect the clinical course and outcome of bacterial meningitis. In Africa, viruses might be responsible for 14-25% of all meningitis cases. However, only few studies from Africa have reported detection of viruses in the cerebrospinal fluid (CSF) or mixed viral-bacterial infections of the central nervous system (CNS). The aim of the present study was to investigate the presence of picornaviruses in the CSF of children suffering from meningitis in Luanda, Angola. The study included 142 consecutive children enrolled in a prospective study of bacterial meningitis in Luanda between 2005 and 2006, from whom a CSF sample was available. CSF samples were obtained at hospital admission, stored in a deep-freeze, and transported to Finland for testing by real-time PCR for picornaviruses. Enteroviruses were detected in 4 (3%) of 142 children with presumed bacterial meningitis. A 5-month-old girl with rhinovirus and Haemophilus influenzae meningitis recovered uneventfully. An 8-year-old girl with human enterovirus and pneumococcal meningitis developed no sequelae. A 2-month-old girl with human enterovirus and malaria recovered quickly. A 7-month-old girl with human enterovirus was treated for presumed tuberculous meningitis and survived with severe sequelae. Mixed infections of the CNS with picornaviruses and bacteria are rare. Detection of an enterovirus does not affect the clinical picture and outcome of bacterial meningitis.

Occurrence of human bocaviruses and parvovirus 4 in solid tissues.

Human bocaviruses 1-4 (HBoV1-4) and parvovirus 4 (PARV4) are recently discovered human parvoviruses. HBoV1 is associated with respiratory infections of young children, while HBoV2-4 are enteric viruses. The clinical manifestations of PARV4 remain unknown. The objective of this study was to determine whether the DNAs of HBoV1-4 and PARV4 persist in human tissues long after primary infection. Biopsies of tonsillar tissue, skin, and synovia were examined for HBoV1-4 DNA and PARV4 DNA by PCR. Serum samples from the tissue donors were assayed for HBoV1 and PARV4 IgG and IgM antibodies. To obtain species-specific seroprevalences for HBoV1 and for HBoV2/3 combined, the sera were analyzed after virus-like particle (VLP) competition. While HBoV1 DNA was detected exclusively in the tonsillar tissues of 16/438 individuals (3.7%), all of them ≤8 years of age. HBoV2-4 and PARV4 DNAs were absent from all tissue types. HBoV1 IgG seroprevalence was 94.9%. No subject had HBoV1 or PARV4 IgM, nor did they have PARV4 IgG. The results indicate that HBoV1 DNA occurred in a small proportion of tonsils of young children after recent primary HBoV1 infection, but did not persist long in the other tissue types studied, unlike parvovirus B19 DNA. The results obtained by the PARV4 assays are in line with previous results on PARV4 epidemiology.

Prognostic accuracy of five simple scales in childhood bacterial meningitis.

BACKGROUND: In childhood acute bacterial meningitis, the level of consciousness, measured with the Glasgow coma scale (GCS) or the Blantyre coma scale (BCS), is the most important predictor of outcome. The Herson-Todd scale (HTS) was developed for Haemophilus influenzae meningitis. Our objective was to identify prognostic factors, to form a simple scale, and to compare the predictive accuracy of these scales. METHODS: Seven hundred and twenty-three children with bacterial meningitis in Luanda were scored by GCS, BCS, and HTS. The simple Luanda scale (SLS), based on our entire database, comprised domestic electricity, days of illness, convulsions, consciousness, and dyspnoea at presentation. The Bayesian Luanda scale (BLS) added blood glucose concentration. The accuracy of the 5 scales was determined for 491 children without an underlying condition, against the outcomes of death, severe neurological sequelae or death, or a poor outcome (severe neurological sequelae, death, or deafness), at hospital discharge. RESULTS: The highest accuracy was achieved with the BLS, whose area under the curve (AUC) for death was 0.83, for severe neurological sequelae or death was 0.84, and for poor outcome was 0.82. Overall, the AUCs for SLS were ≥0.79, for GCS were ≥0.76, for BCS were ≥0.74, and for HTS were ≥0.68. CONCLUSIONS: Adding laboratory parameters to a simple scoring system, such as the SLS, improves the prognostic accuracy only little in bacterial meningitis.

Hearing loss in Angolan children with sickle-cell disease.

BACKGROUND: Hearing loss and pneumococcal infections occur in children with sickle-cell disease (SCD). We assessed the prevalence of hearing loss and otological findings, especially otitis media, among children with SCD in Luanda, Angola. METHODS: We performed otorhinolaryngological examination, tympanometry and, at ages over 5 years, pure-tone audiometry, in 61 outpatients of the SCD clinic and 61 healthy controls in the Paediatric Hospital of Luanda. RESULTS: Bilateral hearing loss exceeding 25 dB occurred in nine (36%; median age 7.8 years) SCD children versus three (11%; P = 0.047) control children. The hearing loss in the SCD group was predominantly mild (26-40 dB), involved low- and speech-range frequencies, and was sex independent. Acute otitis media occurred in two (3%) children with SCD versus four (6%; P = 0.68) control children, chronic otitis in zero versus two (3%; P = 0.50), and middle-ear effusion in one versus one (2%; P > 0.99). We found no significant differences in the otological profiles of the study groups. CONCLUSIONS: In sub-Saharan Africa, hearing screening of SCD children is a must at preschool age. The actual prevalence of otitis media and its role in the cause of hearing loss in children with SCD remain subjects for further research.
