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.

Ethmoidectomy decompression for the treatment of Graves' optic neuropathy.

When orbital decompression becomes necessary in Graves' optic neuropathy, medial wall decompression is a necessary component of the decompression procedure. The ethmoidectomy approach allows more direct visualization of the posterior ethmoids and sphenoids to effect maximum decompression. This is particularly important in cases in which computed tomography shows the medial rectus muscle to be enlarged posteriorly in the orbit. The procedure provides excellent visualization of the medial rectus. As with any medial wall decompression procedure, postoperative restriction of horizontal motility is a frequent complication, often necessitating more than one subsequent operation. The authors describe their experience with the procedure in 25 patients with Graves' optic neuropathy.

Pleomorphic adenoma: a preliminary histopathologic comparison between tumors occurring in the deep and superficial lobes of the parotid gland.

Twenty-four cases of pleomorphic adenoma of the parotid gland were retrospectively reviewed. The histopathological features of capsular thickness, penetration and completeness, tumoral cell population and mitotic activity were analyzed in twelve superficial lobe and twelve deep lobe tumors. The capsules were found to be significantly thicker and less likely to be penetrated by tumor in the deep lobe group. No significant differences in completeness of encapsulation, cell population or mitotic activity were found between the two groups. This may explain the clinical suggestion that the less aggressive surgical approach which is often performed does not compromise the prognosis for recurrence in the deep lobe lesions.

AIDS-related Kaposi's sarcoma of the sphenoid sinus.

The head and neck region is frequently involved by AIDS-related Kaposi's sarcoma, the oral cavity being the most common site of occurrence. We report on the first case of AIDS-related Kaposi's sarcoma involving the sphenoid sinus where radionuclide bone scanning and MRI were effective in suggesting the diagnosis.

Air cyst of the maxillary sinus (pneumosinus dilatans, pneumocoele).

A cystic dilatation of a paranasal sinus by an entrapped air mass has been termed pneumosinus dilatans or a pneumocoele. The occurrence of this condition in the maxillary sinus is quite rare. In the present case, a mid-face mass mimicking an osteoma was the presenting sign of the disease. The pathogenesis, clinical features and radiological aspects of this entity are reviewed. In order to avoid confusion with other conditions of different aetiopathogenesis, we propose to label the lesion as 'air cyst' of the paranasal sinus, a term that best describes the nature of the lesion.

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.

Necrotizing soft-tissue infections in the head and neck: a clinicopathological study.

The clinicopathological aspects of 15 patients with necrotizing soft-tissue infections in the head and neck are reviewed. Our relatively large series suggests that the disease occurs more frequently than described in the literature. Histological studies showed that tissue superficial and deep to the fascia is frequently involved with the infectious inflammatory process, even in early stages of the disease. These pathologic changes were also found in healthy-appearing tissues at the periphery of the lesions. The early recognition of the disease and the prompt and aggressive surgical and medical therapeutic approach have resulted in far lower mortality rates (7%) than those reported in the literature. Frozen-section examination contributed to the maximal eradication of the pathologic process. This successful outcome was achieved in spite of the adverse associated clinical conditions, such as old age, debilitating disease, or complications, observed in half of the patients.

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.

Adenoid cystic carcinoma of the external auditory canal.

Adenoid cystic carcinoma of the external auditory canal is much less common than squamous cell carcinoma and basal cell carcinoma. Signs and symptoms of the case presented here consisted of a longstanding discharging ear, a progressive hearing loss, and the presence of a circumferential subcutaneous induration in the distal third of the external auditory canal. No dizziness, tinnitus, or facial weakness was present. Computed tomography showed a soft tissue mass in the external auditory canal and middle ear with no lytic areas of the mastoid or the temporal region. A biopsy specimen was interpreted as an adenoid cystic carcinoma. Treatment consisted of radical excision of the external auditory canal via a modified temporal bone resection. This radical approach resulted in the local eradication of the lesion.

[Cefaclor and trimethoprim-sulfamethoxazole for recurrent otitis media].

The efficacy of cefaclor and of trimethoprim-sulfamethoxazole (TMP-SMX) in the management of recurrent otitis media was evaluated in a randomized single-blind controlled trial. The median age of the patients was 12 months (range 5-37); there were 37 boys and 19 girls. All had received 1 or more courses of antibacterials for acute otitis media in the previous 2-3 weeks. 27 were treated with oral cefaclor suspension, 40 mg/kg/day in 3 divided doses, and 29 with 1 mg/kg/day of TMP-SMX (trimethoprim 8 mg, sulfamethoxazole 40 mg) in 2 divided doses, each group for 10 days. 70% of the cefaclor group and 90% of the TMP-SMX group were cured after the 10 days of therapy (0.1 greater than p greater than 0.05). Results were not better on the 21st day as compared with the 10th. Our data indicate a mild preference for TMP-SMX (although p was not less than 0.05), since it needs to be given only twice a day and costs less than cefaclor.
