Return to contact sports following infectious mononucleosis: the role of serial ultrasonography.

Splenic rupture is a rare but potentially fatal complication of infectious mononucleosis. Athletes returning to contact sports following infectious mononucleosis are at potential risk of splenic rupture secondary to abdominal trauma. No clear consensus exists as to when it is safe to allow these athletes to return to contact sports. Suggested periods of abstinence have ranged from 2 weeks to 6 months. We outline our experiences with the use of abdominal ultrasonography at 1 month after the diagnosis of infectious mononucleosis as a means of determining when athletes can safely return to contact sports. Our study group was made up of 19 such patients (mean age: 16.7 yr). We found that 16 of these patients (84%) had normal splenic dimensions on ultrasonography 1 month after diagnosis, and they were therefore allowed to return to contact sports. While the remaining 3 patients had an enlarged spleen at 1 month, their splenic dimensions had all returned to normal when ultrasonographic examination was repeated at 2 months postdiagnosis. We conclude that serial abdominal ultrasonography allows for informed decision making in determining when athletes can safely return to contact sports following infectious mononucleosis.

Laryngotracheoplasty to avoid tracheostomy in neonatal and infant subglottic stenosis.

OBJECTIVE: To outline the authors' experiences with performing laryngotracheoplasty as an alternative to tracheostomy in neonates and infants with symptomatic subglottic stenosis (SGS). STUDY DESIGN: Case series with chart review. SETTING: A tertiary referral pediatric hospital. SUBJECTS AND METHODS: Patients younger than 12 months undergoing single-stage laryngotracheoplasty for SGS at the authors' institution over a 3-year period. RESULTS: Ten patients (8 boys and 2 girls) underwent single-stage laryngotracheoplasty during the study period. There were 9 cases of acquired SGS and 1 case of congenital SGS. Eight patients had grade III SGS, and 2 patients had grade II SGS. In 9 of 10 patients, the procedure performed was an anterior cricoid split (ACS) and posterior cricoid split (PCS), with the placement of an anterior thyroid ala cartilage graft. One patient underwent ACS and PCS with the placement of a posterior rib cartilage graft, in combination with a right vocal cord lateralization. The mean period of intubation after surgery was 6.8 days (range, 5-9 days). Nine of 10 patients had a complete resolution of their airway symptoms following airway surgery, with a mean duration of follow-up of 305 days (range, 30-780 days). One patient required the placement of a tracheostomy tube 69 days postoperatively due to a failure to wean from ventilation in the setting of multiple comorbidities. CONCLUSION: Laryngotracheoplasty is a safe and effective alternative to long-term tracheostomy in infants and neonates with symptomatic SGS.

Objective assessment of supraglottoplasty outcomes using polysomnography.

OBJECTIVE: Supraglottoplasty is well documented as an effective procedure in the management of moderate to severe laryngomalacia. Traditionally assessed outcomes in the treatment of laryngomalacia include: reduced stridor, improved feeding and a resumption of weight-gain. Previous authors have documented the use of polysomnography in assessing the severity of paediatric laryngeal abnormalities. The aim of the current study was to objectively assess the efficacy of supraglottoplasty for laryngomalacia by comparing data from pre- and post-operative polysomnography. METHODS: A retrospective review was performed of patients undergoing supraglottoplasty for laryngomalacia at a tertiary referral paediatric hospital over a 35-month period. Patients were required to have undergone full overnight polysomnography both before and after supraglottoplasty. Pre- and post-operative polysomnographic results were compared and the statistical significance between mean values was determined. RESULTS: From a total of 46 patients, 10 were suitable for inclusion into the study. Mean age at first presentation was 2 months and 19 days (range 30-134 days). The surgical procedure performed was bilateral division of aryepiglottic folds alone in 1 patient (1/10), bilateral division of aryepiglottic folds and bilateral trimming of arytenoid mucosa in 5 patients (5/10) and bilateral aryepiglottic fold division, bilateral arytenoid mucosal trimming and epiglottic trimming or epiglottopexy in 4 patients (4/10). Statistically significant improvements occurred in mean values for Total Sleep Time (TST) (P=0.049), Lowest Oxygen Saturation Levels (SpO2 nadir) (P=0.006), Obstructive Apnoea Hypopnoea Index (OAHI) (P=0.009) and Respiratory Disturbance Index (RDI) (P=0.002), following supraglottoplasty. An improvement in mean Transcutaneous Carbon Dioxide (TcCO2) value occurred, but did not achieve statistical significance (57.1 vs. 52.8) (P=0.259). The mean age at which post-operative polysomnography confirmed a reversal of abnormal respiratory parameters following surgery was 5 months and 18 days. CONCLUSIONS: Polysomnography is an effective method for objectively assessing the efficacy of supraglottoplasty for laryngomalacia. Supraglottoplasty effectively reverses the abnormal respiratory parameters occurring in moderate to severe laryngomalacia.

Primary care management of otitis media among Australian children.

Acute otitis media (AOM) is diagnosed on the basis of acute onset of pain and fever; a red, bulging tympanic membrane; and middle ear effusion. AOM is managed with analgesia (paracetamol or non-steroidal anti-inflammatory drugs). Antibiotic therapy is minimally effective for most patients; it is most effective for children < 2 years with bilateral otitis media and for children with discharging ears. National guidelines recommend antibiotic therapy for Indigenous children with AOM. Evidence for corticosteroids, topical analgesia and xylitol are scant. Otitis media with effusion (OME) is diagnosed as the presence of middle ear effusion (type B tympanogram or immobile tympanic membrane on pneumatic otoscopy) without AOM criteria. Well children with OME with no speech and language delays can be observed for the first 3 months; perform audiological evaluation and refer to an ear, nose and throat (ENT) specialist if they have bilateral hearing impairment > 30 dB or persistent effusion. Children with effusions persisting longer than 3 months can benefit from a 2-4-week course of amoxycillin. Chronic suppurative otitis media is a chronic discharge through a tympanic membrane perforation. It is managed with regular ear cleaning (dry mopping or povidone-iodine [Betadine] washouts) until discharge resolves; topical ear drops (eg, ciprofloxacin); audiological evaluation; and ENT review.

Complications of otitis media in Indigenous and non-Indigenous children.

In Australia, three to five children die each year because of otitis media complications, and 15 children will suffer permanent hearing loss each year as a result of otitis media. Extracranial complications occur most commonly, and include mastoiditis, cholesteatoma and otitis media with perforation. Intracranial complications are less common, and include meningitis, brain abscess and lateral sinus thrombosis. In Australia, approximately 60% of extracranial and intracranial complications of otitis media occur in children. The contrasting rates of childhood otitis media among Indigenous and non-Indigenous children have implications for the frequency and types of complications occurring in both groups. Otitis media with effusion and acute otitis media predominate among non-Indigenous children, whereas chronic suppurative otitis media (CSOM) occurs most commonly among Indigenous children. The incidence of mastoiditis in Australia is low by international standards (2/100,000 children), but cholesteatoma rates among Indigenous children in Australia are higher than previously estimated (up to 10% in CSOM). A high rate of chronic tympanic membrane perforation occurs among Indigenous children, estimated to be as high as 80%. Intracranial complications of otitis media are uncommon, but are potentially life-threatening and are more likely to occur among Indigenous than non-Indigenous children. Reduced access to medical care, lower socioeconomic status and remote living conditions mean that levels of early childhood hearing loss among Indigenous children are likely to be underestimated. This has implications for early childhood speech and language development and education.
