Otolaryngology and infectious disease team approach for outpatient management of serious pediatric infections requiring parenteral antibiotic therapy.

Children with community-acquired serious otolaryngologic infections are conventionally hospitalized for parenteral antibiotic therapy. However, effective and safe outpatient therapy is desirable since it is less traumatic and less costly. During a 24-month period outpatient parenteral antibiotic therapy, usually once daily i.m. ceftriaxone, was evaluated in 41 children with serious otolaryngologic infections (acute mastoiditis, complicated otitis media, severe external otitis and severe sinusitis with orbital or periorbital involvement). Daily visits and compliant capable parents were considered essential for outpatient management. Diagnosis, plan for management and daily follow-up evaluations were carried out in cooperation by otolaryngology and infectious disease specialists. Nineteen children (45%) were treated initially in the hospital and 22 children (55%) were treated entirely as outpatients. The mean duration of outpatient treatment, using once daily i.m. ceftriaxone was 5.7 days (range 1-13). The overall clinical cure rate was 98% and no serious side effects were observed. One case of sinusitis-orbital cellulitis relapsed during therapy. Most patients and parents returned to normal life activities within 72 h from starting outpatient therapy. Our data suggest that many children with serious otolaryngologic infections can be managed successfully and safely as outpatients by a combined team of otolaryngology and infectious disease specialists.

Medical treatment of chronic suppurative otitis media without cholesteatoma in children--a two-year follow-up.

A prospective long-term study was carried out in 48 infants and children with chronic suppurative otitis media without cholesteatoma treated initially with wide spectrum intravenous antibiotics and suction and debridement. Patients were followed for a period of two years. All children were cured after completion of therapy. At 3 and 6 months follow-up 75% of the children were still free of discharge and at 12, 18 and 24 months the proportion of dry ears dropped to 71%, 66% and 52%, respectively. Eighty percent of all recurrences developed already during the first 6 months of follow-up. Pseudomonas aeruginosa was the most common pathogen isolated, both in the initial and recurrent bouts of the disease, and was commonly associated with other pathogens. Children with early reappearance of ear discharge were less likely to benefit from further antimicrobial or surgical treatment. The recurrence rate was not affected by the antibiotic regimen, age, duration of drainage before treatment or the presence of granulation tissue. No intracranial or intratemporal complications were observed during the follow-up period.

Outpatient management of chronic suppurative otitis media without cholesteatoma in children.

Prolonged antipseudomonal parenteral antibiotic therapy combined with daily aural toilet has been effective in resolving long standing ear discharge in children with chronic suppurative otitis media. However, such treatment suffered from the disadvantages of prolonged hospitalization. We conducted a prospective study to investigate the feasibility and efficacy of exclusive outpatient treatment of children with chronic suppurative otitis media without cholesteatoma who had failed ototopical/oral antimicrobial therapy. The treatment consisted of daily aural toilet (suction and debridement) and twice daily parenteral ceftazidime (50 mg/kg/dose). Thirty-seven children were included. The duration of discharge from the ear before treatment was 6 to 121 months (median, 30 months). Aerobic cultures yielded Pseudomonas aeruginosa in 97%, often with other organisms. The management and follow-up were performed jointly by otolaryngology and infectious diseases physicians using the hospital ambulatory services. The route of ceftazidime administration (intravenous or intramuscular) was chosen according to the parents' and patients' convenience. Discharge stopped within 3 to 20 days (median, 8 days) in all children but one. Seventy-six percent of the 29 children available for follow-up 12 months after treatment were still free of discharge. Our results demonstrate that a regiment combining daily aural toilet and twice daily parenteral ceftazidime is highly efficacious in resolving ear discharge in children with chronic suppurative otitis media without cholesteatoma and that such a regimen does not require hospitalization.

Aerobic bacteriology of chronic suppurative otitis media without cholesteatoma in children.

Medical management of chronic suppurative otitis media without cholesteatoma in children was shown recently to be efficacious. We undertook a prospective study in order to determine 1) the organisms associated with the disease and their sensitivity to various antibiotics and 2) their association with clinical variables. Pseudomonas was isolated from 84% of the patients, enteric gram-negative bacilli from 32%, Staphylococcus aureus from 20%, streptococci from 14%, and Hemophilus influenzae from 15%. Pseudomonas aeruginosa was the sole isolate in 48 of the 128 patients (38%). The sensitivity of P aeruginosa (78 isolates) was 100% (of isolates) to mezlocillin and ciprofloxacin, 99% to tobramycin and ceftazidime, 97% to piperacillin, 94% to gentamicin, and 78% to ceftriaxone. The isolated organisms and their sensitivity to antibiotics were not associated with age, sex, duration of otorrhea, or the presence of granulation tissue or polyps. We believe that our data may contribute to the appropriate choice of antibiotics when nonsurgical management of chronic suppurative otitis media without cholesteatoma is considered.

Effects of sodium hypochlorite on soft tissues after its inadvertent injection beyond the root apex.

The effects of an inadvertent injection of sodium hypochlorite into the cheek during irrigation of the right maxillary central incisor root canal are reported. The patient suffered from severe pain, edema, and necrosis of subcutaneous tissues and mucosa. Surgical intervention was necessary to contain the destructive process which extended from the upper lip to the right eye. The histopathological examination demonstrated the high cytotoxicity of sodium hypochlorite on vital tissue.

Salmonella neck abscess associated with jugular vein thrombosis.

An unusual case of synergistic infection caused by Salmonella paratyphi and anaerobic streptococcus resulting in necrotizing cervical infection associated with deep neck abscess and internal jugular vein thrombosis, is presented. Salmonella acting as an oxygen consumer in the infected tissues, facilitates the growth of anaerobic cocci, hence the development of a devastating soft tissue infection. The precipitating cause was a tonsillar infection developing due to 'post-anginal sepsis'. The aetiopathogenesis of the cervical infection is discussed.

Chronic suppurative otitis media without cholesteatoma in children in southern Israel: incidence and risk factors.

The incidence and risk factors for chronic suppurative otitis media without cholesteatoma in children in Southern Israel were determined by comparing 88 children with the disease to 76 controls with similar age distribution who visited 3 clinics serving representative populations of the region. Data were collected during the child's visit to the clinic by means of a structured interview with the parents and by extracting information from medical records. The calculated yearly incidence was 39/100,000 children 0 to 15 years of age. Significantly increased risk for chronic suppurative otitis media was associated with a history of acute and recurrent otitis media, a parental history of chronic otitis media, larger families and more siblings, a higher crowding index and care in large daycare centers. The sex, parental age and education, allergy, sinusitis and recurrent upper respiratory tract infections were not associated with chronic suppurative otitis media.

Maxillary myxoma in children.

Myxoma of the maxilla is a rare, slowly growing, benign mesenchymal tumor. Pathologically, it may be difficult to differentiate from other tumors with myxoid stroma and is occasionally misinterpreted as malignant. This tumor is particularly uncommon in children; in a search of the literature, we were able to document only 17 cases of myxomas in the maxilla in patients aged 14 years or less. This report on two children with myxoma of the maxilla emphasizes the importance of including myxoma in the differential diagnosis of children with maxillofacial tumors, and underlines the difficulties in making a correct diagnosis.

Medical management of chronic suppurative otitis media without cholesteatoma in children.

To determine whether systemic administration of antibiotics may eliminate or reduce the need for tympanomastoid surgery in chronic suppurative otitis media without cholesteatoma, we undertook a randomized, prospective study comparing three regimens: (1) daily suction and débridement, with intravenous administration of mezlocillin until 3 days after the discharge stopped, (2) daily suction and débridement, with intravenous use of ceftazidime until 3 days after the discharge stopped, and (3) daily suction and débridement without antibiotics. No topical antimicrobial agents were used during the study. Fifty-one patients were included, and 48 children completed the study. The duration of discharge from the ear before treatment was 2 to 123 months (median 20 months). In 26 patients (51%), the disease was bilateral. Aerobic cultures, obtained with the Alden-Senturia middle ear aspirator, yielded Pseudomonas aeruginosa in 98%, enteric gram-negative bacilli in 33%, staphylococci in 25%, and Haemophilus influenzae in 12%. The first 33 patients were randomly assigned to one of the three regimens. In the 21 patients treated with suction and antibiotics (either mezlocillin or ceftazidime), the discharge stopped completely, versus in only 1 (8%) of 12 patients in the suction-only regimen (p less than 0.01). Therefore the following 18 patients were randomly assigned to one of only two groups, which included the two suction-and-antibiotic regimens. In all patients treated initially with antibiotics, discharge stopped after 4 to 18 days (mean 12.0 days), but 25% needed treatment for greater than 14 days. Amoxicillin prophylaxis was administered to 27 (56%) of the patients after completion of therapy. All patients were followed for 6 months. Drainage recurred in 12 (25%) patients during the first 3 months after the study. The recurrence rate was not affected by the antibiotic regimen, the patient's age, the duration of drainage before initiation of antibiotic therapy, or prophylaxis. We conclude that intravenous wide-spectrum antibiotic therapy in conjunction with daily suction and débridement is efficacious for the treatment of chronic suppurative otitis media without cholesteatoma.

Granular cell lesions in head and neck: a clinicopathological study.

Twenty-five cases of granular cell lesions in the region of the head and neck are presented. The adult form (18 cases) was more frequent in women, and the most frequent sites were the tongue, the skin, and subcutaneous tissues, followed by the lip and buccal mucosa. One lesion occurred in the larynx. The congenital forms (7 cases) all occurred in female infants and involved the mucosa overlying either the anterior ridge of the maxilla or the mandible. Immunohistochemical studies revealed positive staining for S100 protein in all the granular cell tumors of the adult but in none of the congenital granular cell epulides. Embryonic antigen was present in the cells of all the congenital cases and in three-quarters of the adult cases. The significance of the histological and immunohistochemical findings is discussed. We conclude that the congenital and adult lesions are similar morphologically but are not necessarily of similar histogenesis. The findings with respect to S100 protein favor a neural (Schwann cell) origin of the adult granular cell tumor, but not the congenital form.

Ventricular dysfunction in children with obstructive sleep apnea: radionuclide assessment.

Ventricular function was evaluated using radionuclide ventriculography in 27 children with oropharyngeal obstruction and clinical features of obstructive sleep apnea. Their mean age was 3.5 years (9 months to 7.5 years). Conventional clinical assessment did not detect cardiac involvement in 25 of 27 children; however, reduced right ventricular ejection fraction (less than 35%) was found in 10 (37%) patients (mean: 19.5 +/- 2.3% SE, range: 8-28%). In 18 patients wall motion abnormality was detected. In 11 children in whom radionuclide ventriculography was performed before and after adenotonsillectomy, right ventricular ejection fraction rose from 24.4 +/- 3.6% to 46.7 +/- 3.4% (P less than 0.005), and in all cases wall motion showed a definite improvement. In five children, left ventricular ejection fraction rose greater than 10% after removal of oropharyngeal obstruction. It is concluded that right ventricular function may be compromised in children with obstructive sleep apnea secondary to adenotonsillar hypertrophy, even before clinical signs of cardiac involvement are present.

Obstructive sleep apnea in young infants.

Obstructive sleep apnea (OSA) was diagnosed in 14 infants less than 18 months of age. Snoring, apnea, failure to thrive, developmental delay and recurrent respiratory infections were the main presenting symptoms. The diagnosis was made by polysomnographic studies or overnight monitoring. Adenotonsillectomy resulted in the relief of symptoms and signs in 13 children. In one infant prolonged nasopharyngeal intubation was needed. An increased awareness of OSA in young infants may prevent the delay in diagnosis, will allow early treatment and thus prevent the development of sequela or complications associated with this syndrome.

Acute upper airway obstruction due to myxoedema and upper airway abnormalities.

Acute upper airway obstruction (U.A.O.) in adults is not as common as in children. The most common cause is choking on food, and associated endocrine disorders are among the rarest causes. Airway obstruction in adults has a variety of symptom-complexes, which manifest themselves as acute or chronic (incomplete) conditions, or only during sleep (sleep apnoea syndrome). There is an overlap between these symptoms and their aetiologies. A case of acute U.A.O. at the pharyngeal level in a hypothyroid patient is presented. Following airway relief and supplemental thyroxin treatment, the patient became asymptomatic during the daytime, but showed a severe form of sleep apnoea syndrome which required further surgical treatment to reach full cure.

Cor pulmonale due to adenoidal or tonsillar hypertrophy or both in children. Noninvasive diagnosis and follow-up.

Four children, aged 1 to 3 1/2, were first seen with cor pulmonale, pulmonary edema and severe respiratory distress due to chronic upper airway obstruction secondary to adenoidal or tonsillar hypertrophy or both. Arterial blood gas values, electrocardiograms and chest x-ray films were compatible with cor pulmonale. Echocardiography (four cases) and radionuclide angiography (two cases) showed severe right ventricular and right atrial dilation with reduced right ventricular ejection fraction. Following surgery, all four children improved; their echocardiographic and radionuclide findings returned to normal. Cardiac catheterization, traditionally performed in such cases, was unnecessary. The diagnosis and follow-up of this syndrome are adequately performed noninvasively.
