The ENT manifestations of HIV infection in children

This study identified the ENT symptoms of 66 HIV infected children over an 8 year period (1986-1993) at Great Ormond Street Hospital for Children. The incidence, nature and age of onset of ENT symptoms were investigated; 91% of the children had ENT symptoms, the most common being cervical lymphadenopathy, oro-oesophageal candidiasis and otitis media. The HIV infected children suffered from the common ENT diseases of childhood. They also presented with specific conditions such as diffuse parotid swelling. Therefore, their clinical features differed from HIV infected adults as well as non-infected children. An increasing incidence of paediatric HIV infection was demonstrated by the study. Most were due to vertical transmission. ENT surgeons are likely to see more HIV infected children in future, either with the usual ENT diseases of childhood (to which they seem more susceptible) or with HIV-specific conditions. Although the diagnosis of HIV may be known, the ENT condition could be the initial presentation suggestive of immunodeficiency.     

ENT presentations in children with HIV infection

Illnesses of the ear, nose and throat (ENT) are common in children with human immunodeficiency virus (HIV) infection. We reviewed the case files of 107 HIV seropositive children in the paediatric HIV unit at St Mary's Hospital. The prevalence, age of onset and type of ENT disease were reviewed. We also determined sex distribution, maternal country of origin and mode of transmission of HIV. Fifty per cent of the HIV children had ENT illnesses. Fifty-five per cent of the children presented with their first ENT symptom before age 3 years with 98% of the children having ENT manifestations by age 9 years. The commonest ENT diseases were cervical lymphadenopathy (70%), otitis media (46%), oral candidiasis (35%) and adenotonsillar disease (31%). HIV transmission was vertical in 90%. Maternal country of origin was Africa in 70% and the UK in 13%. Compared with previous studies, the proportion of HIV children with ENT problems appears to have decreased. Although our figures report a similar ENT symptom profile, the age at onset of these symptoms has increased.     

Epstein-Barr virus infection as etiological and pathogenetic factor of exudative otitis media in childhood

A detailed examination of 40 children with recurrent exudative otitis media (EOM) using enzyme immunoassay and polymerase chain reaction suggested that ENT pathology in the above children (EOM, adenoiditis, tonsillopharyngitis, sinusitis) may be a complication of acute or chronic Epstein-Barr virus infection (EBVI) because primary EBVI infection or its long-term persistence followed secondary immunodeficiency resulting in lymphoid system impairment and damage of upper airway epithelium. This causes a recurrent and persistent course of EOM. Etiotropic and pathogenetically sound treatment of children with recurrent EOM includes antiviral therapy, immunocorrection, rehabilitation with participation of pediatrician, immunologist, infection therapist.     

Optimizing the diagnosis of gastroesophageal reflux in children with otolaryngologic symptoms

OBJECTIVES: Although many children with otolaryngologic (ENT) symptoms are being treated for gastroesophageal reflux (GER), how to diagnose GER in children with primarily or exclusively ENT symptoms has yet to be determined. This study compares the incidences of pathologic GER in the upper verses the lower esophagus in a cohort of children with ENT symptoms that were screened for GER. METHODS: The results of extended dual channel intraesophageal pH probe monitoring obtained from 14 infants and 14 children with ENT symptoms were retrospectively analyzed. The percent of total monitoring time that the pH was less than 4, reflux index (RI) was determined. The upper limits of normal distal and proximal esophageal RI were based on published data. To evaluate our results, upper esophageal reflux (UER) was also determined in 27 infants and children without ENT or pulmonary symptoms, who had normal lower esophageal reflux (LER) values. RESULTS: Mean upper esophageal RIs in the infants and children with normal LER were similar to previously published values for control infants and adults. Four (29%) of the ENT infants, 11 (79%) of the older ENT children, and 54% of the entire cohort had increased esophageal acid exposure. However, nine (60%) of the 15 pediatric ENT patients with GER had pH abnormalities limited to the upper esophagus. CONCLUSIONS: Standard distal pH probe monitoring alone gives a false negative result in a substantial proportion of the infants and children with ENT symptoms being evaluated for GER. Beyond its value in clinical practice, UER testing should be employed in research studies that evaluate the impact of GER therapy on ENT symptoms.     

Current indications for (adeno)tonsillectomy in children: a survey in The Netherlands

OBJECTIVE: Despite the fact that (adeno)tonsillectomy is one of the procedures most frequently performed on children, studies of current indications are scarce. The purpose of this study is to determine the indications for (adeno)tonsillectomy in children younger than 15 years of age according to Dutch ENT surgeons and general practitioners (GPs). METHODS: During a period of 8 months, 18 ENT surgeons in seven ENT practices and 210 referring GPs filled out standard questionnaires for 349 children listed for tonsil surgery. RESULTS: Apart from recurrent tonsillitis (ENT: 40%, GP: 35%), findings such as enlarged tonsils (ENT: 42%, GP: 24%) and tonsillar crypt debris (ENT: 29%, GP: 17%) and non-specific symptoms such as listlessness (ENT: 28%, GP: 19%) and poor appetite (ENT: 28%, GP: 16%) were considered important criteria for surgery. Symptoms of obstructive sleep apnea were present in 25% (ENT) and 6% (GP) of patients but were considered indicative for surgery in only 11% (ENT) and 4% (GP). In contrast to ENT surgeons, GPs considered otitis media and hearing loss relatively important for (adeno)tonsillectomy. CONCLUSIONS: Apart from the generally accepted indications such as recurrent tonsillitis and obstructive sleep apnea, other indications play an equally important role in the decision to perform tonsil surgery in The Netherlands.     

Pattern of ENT problems in patients with primary defects of humoral immunity

Fibroendoscopy, otomicroscopy, rhinomanometry, CT of the paranasal sinuses, examination of mucociliary transport in the nasal cavity and ENT microflora, threshold tonal audiometry, impedance audiometry were performed in 20 patients with primary immunodeficiency. The patients were found to have paranasal inflammation, slow mucociliary transport, abnormal nasal breathing, acoustic tube dysfunction, chronic inflammation or exudation in the middle ear, conductive hipoacusis, etc. The findings confirm that ENT are target organs in primary immunodeficiency.     

Prognostic factors for persistent otitis media with effusion in infants.

OBJECTIVE: To study prognostic factors for persistent otitis media with effusion (OME) in a birth cohort of 30,099 children born in the eastern part of The Netherlands between January 1, 1996, and April 1, 1997. DESIGN: Case-referent study. SUBJECTS: Children who failed a triple hearing test before their first birthday and were subsequently diagnosed with bilateral OME during 3 of the 4 bimonthly visits to an ear, nose, and throat (ENT) department (n = 372). The persistent cases were compared with 3 referent groups: (1) all the children who attended the first of 3 hearing tests; (2) all the children of the birth cohort who were referred to an ENT department after the third hearing test; and (3) all the children who were diagnosed with bilateral OME during the first visit to an ENT department. RESULTS: When all the children who participated in the first hearing test were taken as referents, persistent OME was associated with upper respiratory tract infections, attending a day-care center, having older siblings, and a family history of otitis media. When all the children who were referred to an ENT department were taken as referents, only attending a day-care center was associated with persistent OME. When the children diagnosed with bilateral OME during the first visit to an ENT department were taken as referents, no prognostic factors were found for OME persistence. CONCLUSION: When a child is referred early, an otolaryngologist can ask the parent about the presence of prognostic factors to decide which policy to follow.     

Frequency and structure of chronic diseases of ear, throat and nose among population and their dynamics]

Medical examinations of children and adults have shown that ENT diseases amount to 230 and 190 per 1000, respectively. In terms of types of ENT diseases, chronic tonsilitis (38.4%) and adenoids (23.3%) are most prevalent among children and neurosensory hypoacusis (31.1%) and chronic pharyngitis (19.3%)--among the adult population. Trends in the prevalence and types of chronic ENT diseases have been identified.     

Acute otitis media in children: the strategy of patient care

Acute otitis media in children is an emergency ENT pathology encountered not only by otorhinolaryngologists but also in the practical work of general pediatrists, infectionists, allergologists, and representatives of other medical disciplines. Retrospective analysis demonstrates a progressively increasing ENT morbidity rate, especially that of non-purulent forms. Clinical and laboratory characteristics of 130 emergency patients examined in the present study using PCR-testing and bacteriological methods provided data on the activity of Streptococci, Mycoplasmas, Chlamidiae, viruses, and other causative agents of ENT diseases. A strategy for the combined treatment of patients with ENT pathology in an infectious department under control of an otorhinolaryngologist is proposed taking into consideration etiology and pathogenesis of the disease.     

儿童咽喉反流性疾病研究进展

咽喉反流性疾病（1aryngopharyngeal reflux disease,LPRD）是指胃内容物反流至食管上括约肌以上部位,流至咽喉部,与呼吸道和消化道上部组织接触,引起一系列症状和体征的总称。据国外研究表明到耳鼻咽喉科就诊的门诊患者约10%患有LPRD。虽然最近几年,耳鼻咽喉科医师逐渐在重视LPRD的诊疗,但LPRD目前仍是一个不明确的疾病,我们对其真实的发病率及重要性知之甚少,尤其在儿童中LPRD的评估仍存在争议。目前仍有许多工作亟待开展。     

Vertigo and imbalance in children: a retrospective study in a Helsinki University otorhinolaryngology clinic

OBJECTIVE: To determine medical characteristics of children with vertigo who visited an otorhinolaryngology (ENT) clinic during a 5-year period. DESIGN: A retrospective chart review carried out between 2000 and 2004. SETTING: Helsinki University Central Hospital tertiary referral center ENT clinic. SUBJECTS: A total of 119 children (63 girls and 56 boys), ranging in age from 7 months to 17 years (mean age, 10.9 years at examination). MAIN OUTCOME MEASURES: Patients were identified from the ENT clinic database based on hospital discharge codes, with data stored in the database and the SPSS program applied for statistical analysis. RESULTS: Only 0.7% of children visiting the hospital during the 5-year period had vertigo. Benign paroxysmal vertigo of childhood, migraine-associated dizziness, vestibular neuronitis, and otitis media-related dizziness accounted for vertigo in most of the children. CONCLUSIONS: Vertigo is a rare primary complaint of children in an ENT clinic. In achieving a diagnosis, the most valuable tools are medical history, an otoneurologic examination, electronystagmography, and audiography.     

Bacteriology of the middle meatus in children.

Little is known about the bacteriology of the middle meatus in children. Therefore, middle meatal samples were obtained from 50 children who underwent adenoidectomy or adenotonsillectomy, while a group of 50 children submitted to minor non-ENT surgical procedures, were used as a control group. Haemophilus influenzae, Moraxella catarrhalis and Streptococcus pneumoniae were the most frequent cultured organisms, not only in the ENT group (in 68, 50 and 60% of the children respectively) but also in the control group (40, 34 and 50%). These three potential pathogens were more frequently seen among the children of the ENT group but only for H. influenzae was the observed difference statistically significant (P = 0.009). On semiquantitative analysis, there seemed to be more negative cultures or cultures with only a few colonies in the control group, while the richer cultures were obtained from the ENT group. Again, only for H. influenzae, these differences reached a statistical significance (P = 0.003). Streptococcus viridans and Neisseria species, both organisms that might be able to inhibit colonisation by some of the pathogens, were more frequently cultured in the control than in the ENT group: Strep. viridans 30 vs. 10% (P = 0.025) and Neisseria species 14 vs. 2% (P = 0.069).     

Otitis media,respiratory tract infections and hearing loss in pre-term and low birthweight infants¶

In 1983, 1338 liveborn infants with a gestational age of less than 32 weeks and/or a birthweight of less than 1500 g, were enrolled in a national follow-up study in The Netherlands. At the age of 5 years, 966 children were alive. Of these, 927 (96%) were assessed on a home visit 2–6 weeks after their fifth birthday by three specially trained paediatricians. An assessment of ENT morbidity was made and compared with ENT morbidity in full-term children of the same age group. Markedly preterm birth or very low birthweight does not seem to be a risk factor for developing middle ear disease in childhood, however, the rate of ENT problems seems to be higher than in the general population of Dutch preschool children.     

Tinnitus in childhood

Ninety-three healthy children attending routine school and community medical examinations were questioned about tinnitus, 27 of them (29%) described tinnitus. Nine children (9.6%) were bothered by their symptom, the others were not. The incidence of tinnitus in this group was compared with that in a group of 109 children with ear disease. Forty-two children (38.5%) in this group reported tinnitus. This difference is not statistically significant. Details of children attending paediatric ENT clinics were recorded by two ENT surgeons. Four hundred and three children were seen during the study period and of these 13 (3%) reported tinnitus spontaneously. All these children had evidence of ear disease at the time of the consultation. The incidence of tinnitus in those members of this group with abnormal ears was significantly higher than in those children with no evidence of ear disease (P = less than 0.02). Tinnitus may be a manifestation of ear disease in children, but may also be described by children with normal ears.     

Assessment of common otolaryngological diseases among children in rural primary schools in south eastern Nigeria

ObjectivesDespite a global improvement in health care delivery, rural areas in developing countries still have poor access to specialist care. This study aims to assess the occurrences of ear, nose, and throat (ENT) disorders among rural primary school children in south-eastern Nigeria.MethodsTwo rural primary schools were selected randomly from one of the rural regions of South Eastern State of Nigeria. All the pupils of the schools who gave consent were recruited. A structured study proforma investigating the pupils' biodata, otolaryngological symptoms, ear, nose and throat examination findings, was used to evaluate each pupil in the presence of the teachers.ResultsA total of 246 children participated in the study. 145(58.9%) were males while 101(41.1%) were females with a mean age of 8.5 ± 2.4 years. The commonest symptoms reported were nasal discharge (20%) followed by nasal obstruction (11.1%), itching of the ears (11.1%) and sneezing bouts (10%), while 3.7% had subjective hearing impairment. The commonest ENT finding was cerumen auris (43%) and this was observed in 43.4% of males and 42.4% of females, 11% had abnormal tympanic membranes and 20% had grades 3/4 tonsils(Brodsky grading).ConclusionENT disorders are still common in children in the rural areas of developing countries. To avoid the morbidity associated with these preventable and easily manageable disorders, community health workers should be trained to manage common ENT disorders and mobile clinics with scheduled visits made available in areas where ENT services remain inaccessible.     

Snoring,apnoea and ENT symptoms in the paediatric community

This study was designed to determine the prevalence of snoring and assess the extent of associated ENT symptoms in children up to 10 years of age. A questionnaire was presented to the parents of 245 children chosen at random from the General Practice list of the town of Frome, Somerset, UK. The prevalence of snoring was found to be 27%. This increased to 47% in the presence of an upper respiratory infection. Snoring was found to be significantly (P < 0.001) associated with a history of poor hearing, restless sleep, and having a cold. Less significant (P < 0.01) associations occurred with parental smoking, eczema, sleep talking, moving around the bed at night, sore throats, having a runny nose and mouth breathing. Snoring is a common symptom in children up to 10 years of age. Without evidence of other ENT disease the snoring child does not require referral to an ENT department for further investigation.

A national survey of disinfection techniques for flexible nasendoscopes in UK ENT out-patient departments

Flexible fibre-optic nasendoscopes have become a ubiquitous ENT out-patient tool for the inspection of the nasopharynx, larynx and hypopharynx. Disinfection of the instrument between patient use is important to prevent potential spread of infection but the methods used vary considerably. We designed a questionnaire which was piloted and then sent to 115 UK ENT out-patient departments to establish current UK practice. Most units (67 per cent) use a chemical soak system but the type of chemical disinfectant, the method of delivery and the duration of soak varied considerably. A few hospitals use a disposable plastic sheath system and others simply wipe the instrument with an alcohol swab in between patient use. The protocols for disinfection after high risk patients e.g. human immunodeficiency virus (HIV), hepatitis B varied from hospital to hospital. The results demonstrate a lack of standard practice that is wasteful of financial resources and may expose patients to unnecessary risk. There is a need for an authoritative ENT body to publish national guidelines as may be found in other specialties and other countries.     

The influence of application of the assisted reproductive technologies on the state of ENT organs in children

The objective of the present study was to estimate the state of ENT organs in the children born after assisted reproductive technologies (ART). A group of 208 children at the age from 1 to 3 years enrolled in the study included 97 ones born following application of the assisted reproductive technologies. It is concluded that the use of the assisted reproductive technologies has no appreciable effect on the extent and the structure of ENT organ morbidity in the children.     

Acute tonsillitis as the first manifestation of post-transplant lymphoproliferative disorder

Post-transplant lymphoproliferative disorder (PTLD) is a life-threatening complication that may follow orthotopic liver transplantation (OLT) in children. The first symptoms are often in the ear, nose, or throat (ENT) area. This abnormal proliferation of lymphoid cells is related to Epstein-Barr virus (EBV) infection in immunocompromised children. The incidence of PTLD, EBV status before OLT and at the diagnosis of PTLD, delay between OLT and PTLD, localization, pathological investigations, and the treatment and evolution of PTLD were prospectively evaluated in 77 pediatric liver transplant recipients. Eight patients (10%) developed PTLD, all with an ENT presentation. Seven had acute nonbacterial tonsillitis (with a negative throat swab), and 1 had a pharyngolaryngeal localization at the time of the diagnosis. Four patients had associated involvement outside the ENT area. All patients were EBV-seronegative at the time of OLT; 6 underwent seroconversion at the time of diagnosis, and 2 within 9 and 20 months of diagnosis. All patients presented with low-grade PTLD. All patients with acute tonsillitis associated with EBV seroconversion underwent immediate tonsillectomy, and immunosuppression was decreased as much as tolerated. This therapeutic protocol led to complete recovery in all patients. After OLT in children, nonbacterial tonsillar inflammation or hypertrophy associated with an EBV infection is often the first manifestation of PTLD. Tonsillectomy combined with tapering of immunosuppression offers the best chance for a complete recovery.
