[Evaluation of the efficacy of ceftriaxone in acute suppurative otitis media and acute exacerbation of chronic suppurative otitis media. A comparative study with cefotiam as the control].

In order to objectively evaluate the efficacy and the safety of ceftriaxone (CTRX) using once daily administration of 1 g to cases of acute suppurative otitis media and acute exacerbation of chronic suppurative otitis media, a group comparison study by the envelope method was conducted using cefotiam (CTM) as the control drug (2 g twice daily). The results obtained are summarized as follows. 1. Clinical efficacies evaluated by the committee were 71% in the CTRX group and 86% in the CTM group for acute suppurative otitis media, and 63% and 60%, respectively, for chronic suppurative otitis media. When all cases were considered both groups evidenced a clinical efficacy of 64%, and no significant difference was observed between the 2 groups. 2. Clinical efficacies evaluated by the physician in charge were 65% in the CTRX group and 86% in the CTM group for acute suppurative otitis media, and 72% and 60%, respectively, for chronic suppurative otitis media. When all cases were considered efficacies were, respectively, 70% and 64%, showing no significant difference between the 2 groups. 3. Bacteriological efficacies were 88% in the CTRX group and 86% in the CTM group for acute suppurative otitis media, and 74% and 62%, respectively, for chronic suppurative otitis media. With all cases bacterial eradication rates were, respectively, 76% and 67%. Bacterial eradication rates were always higher for the CTRX group than for the CTM group, but the difference was not significant between the 2 groups. 4. Against infections caused by Staphylococcus aureus alone, CTRX showed equal clinical and bacteriological efficacies to CTM. 5. As side effects, dermatitis, vomiting, and malaise were observed in 5 cases (4%) of the CTRX group and 3 cases (3%) of the CTM group. As clinical testing abnormalities, elevations of GOT, GPT, and Al-P, and thrombocytopenia were noted only in 3 cases (5%) of the CTRX group. Furthermore, all of these abnormalities were temporary and of moderate degree or mild, thus the safety of either drug was considered high. 6. Clinical utilities were 71% in the CTRX group and 86% in the CTM group for acute suppurative otitis media, and 72% and 62%, respectively, for chronic suppurative otitis media. When all cases were included, they were 72% and 66%, respectively, and there was no significant difference between the 2 groups. It is concluded from the above results that CTRX is a highly useful drug with once daily administration of 1 g in the treatment of suppurative otitis media.

Medical profile of the language-delayed child: otitis-prone versus otitis-free.

Delay in language development may be associated with an underlying anatomical, neurosensory, or psychological disorder such as: deafness, cerebral palsy, cleft palate, autism, or mental retardation. A condition called specific developmental language delay may occur in children devoid of any other identifiable disorder or developmental delay. Language delay associated with early onset, severe-to-profound hearing impairment has been well documented. Controversial studies have also appeared in the communicative disorders' literature suggesting that fluctuating conductive hearing loss in early childhood can significantly affect the development of language and related academic skills. Some authors have claimed that these deleterious effects can be irreversible. This study focuses on 3 groups of preschool children, in whom hearing acuity has been documented: One group with recurrent otitis and language delay; a second group with an equally well documented otitis history but without language delay; and a third group with documented language delay in the absence of any known predisposing conditions, including early-onset, recurrent otitis media. Prenatal, birth and developmental histories of the children in each group were compared in detail to identify any factors which may enhance or ameliorate the effects of fluctuating conductive hearing loss on language development. In a population of 1864 children (ages 9-59 months) referred for otolaryngologic and/or communicative evaluation, 480 otherwise normal children (67.6% males; 32.4% females) were found to have a history of early-onset, recurrent otitis media and/or delayed speech and language development on the basis of an extensive evaluation battery. This population was further subdivided into 3 groups (I = otitis-positive/normal language; II = otitis-positive/language delay; and III = otitis-free/language delay). Among the 329 children with positive histories for early otitis media (Groups I & II), a significantly higher percentage of those demonstrating language delay were from homes in the lower socio-economic category. Race and sex showed no significant relationship to language delay among the otitis-positive groups, although males were twice as numerous as females in the over-all study population. Articulation errors on speech measures and borderline delays in other developmental milestones (standing, walking, and toilet training) were also significantly greater in the language-delayed group when compared with otitis-positive children whose language was age-appropriate.(ABSTRACT TRUNCATED AT 400 WORDS)

Otitis media in Greenland children: acute, chronic and secretory otitis media in three- to eight-year-olds.

The middle ear status was examined in 142 children aged three to eight years from Sukkertoppen and Kangamiut in Greenland. The investigation is based on social-pediatric and otologic histories and on objective examination using otomicroscopy and tympanometry. Three-fourths of the small children had a previous history of otitis, some with repeated instances. Otomicroscopic findings revealed suppurative, chronic otitis in 6% and sequelae of chronic otitis in 13%. Tympanometry disclosed a reduced middle ear pressure in another 26% of the ears examined. Comparison of children with healthy ears with the groups with affections of the middle ear showed a tendency to an increased risk of otitis in families at a low social stratum, whereas the mode of habitation seemed insignificant. Finally, a large milk intake both in connection with breast-feeding and later in life seemed to reduce the frequency of otitis. The investigation showed that acute otitis and chronic otitis media in particular are more prominent in Greenland than in Denmark. Attention is drawn to the handicap associated with a high incidence of chronic otitis media and the concomitant hearing loss to a population isolated in point of language. The successful achievements of a health information campaign and an active therapeutic program, which has reduced the prevalence of chronic otitis among the Innuit population native to Alaska and Canada, provides the rationale for an increased otologic effort in Greenland.

A history of acute suppurative otitis media and allergic symptomatology in children with chronic secretory otitis media and controls.

The parents of children with secretory otitis media and the parents of healthy children attending for routine school or community medical examinations have been questioned about previous acute otitis media, aural discharge, chronic nasal symptoms and allergic disorders. Eighty-nine pairs of children, matched for age and sex, were available for analysis. There was a significantly higher incidence of acute otitis media, aural discharge and chronic nasal symptoms in the secretory otitis group (P = less than 0.001). Amongst the allergic symptoms and disorders, the only significant differences demonstrated were for drug allergy, eye itching and eye running (P = less than 0.05). The results confirm that a relationship exists between acute otitis media and secretory otitis media and also support the conventional image of the child with secretory otitis as a mouth breather with nasal symptoms. They do not lend support to the view that allergy is an important factor in the pathogenesis of secretory otitis.

Lysozyme activity and immunoglobulins in middle ear effusion fluid in acute purulent otitis media and in otitis media with effusion.

147 samples of punctured middle ear effusion fluid from cases of otitis media with effusion and 150 samples from patients with acute purulent otitis media were tested for lysozyme activity. In otitis media with effusion the concentration was 182.0 U/ml, in acute otitis 433.8 U/ml. The lysozyme concentration in otitis media with effusion depended upon the nature of the effusion. Serous fluid showed an activity of 124.8 U/ml and mucoid 311.6 U/ml, respectively. In culture-positive cases of acute otitis media the lysozyme level was 423.4 U/ml. Culture-negative cases showed about the same concentration, 438.3 U/ml. The possible role of lysozyme in defence systems of the middle ear is discussed.

Surgical management of otitis media and otitis interna.

Surgical management of otitis media and otitis interna includes the following options: lateral bulla osteotomy, ventral bulla osteotomy, or curettage of the tympanic cavity. Because otitis media frequently accompanies chronic nonresponsive otitis externa, one of the above procedures may be combined with operative procedures of the external ear canal. Also, gentle selective curettage of the tympanic cavity may be combined with either lateral or ventral bulla osteotomy in the treatment of otitis media and interna. The choice of surgical procedure(s) should be based on the condition of the external ear canal (vertical and horizontal parts), the duration of clinical signs, response to previous surgery, and the familiarity of the surgeon with the different approaches and techniques. With the increased reporting of long-term results following surgical management of otitis externa, media, and interna, more meaningful conclusions concerning selection of surgical procedure may be made in the future.

Quantitative bone and 67Ga scintigraphy in the differentiation of necrotizing external otitis from severe external otitis.

Qualitative technetium Tc 99m bone scintigraphy using phosphate compounds and gallium 67 scintigraphy were described as a helpful means in diagnosing necrotizing external otitis (NEO). They were, however, claimed to be nonspecific. Quantitative Tc 99m methylene diphosphonate bone scintigraphy and gallium 67 scintigraphy were performed in eight patients with NEO and in 20 patients with severe external otitis, in order to prove usefulness of scintigraphy in the diagnosis of NEO. Ratios of lesion to nonlesion for bone scintigraphy were 1.67 +/- 0.16 in patients with NEO and 1.08 +/- 0.09 in patients with severe external otitis, and for gallium 67 scintigraphy they were 1.35 +/- 0.24 in NEO patients and 1.05 +/- 0.03 in patients with severe external otitis. There was no difference in uptake between diabetic patients with severe external otitis and nondiabetic patients. The scintigraphic studies were also evaluated using a qualitative scoring method (scores 0 to +4), according to the intensity of the radiopharmaceutical uptake. This method was found to be inferior in the diagnosis of NEO compared with the quantitative method. We conclude that lesion-to-nonlesion ratios greater than 1.5 and 1.3 on bone and gallium 67 scintigraphy, respectively, are indicative of NEO. Quantitative bone scintigraphy, which is quicker to perform, may be used as a single imaging modality for the diagnosis of NEO.

[Personal studies on the current spectrum of pathogenic bacteria in otitis externa and chronic otitis media].

From 1985-1987 smears (for Gram staining) and swabs (for culture and antibiogram) were done in 294 patients suffering from chronic otitis media, and in 67 cases of external otitis. Besides the comparison of these two procedures, the microbial spectrum in case of external otitis and chronic otitis media is considered and compared to the literature. Pseudomonas aeruginosa and Staphylococcus aureus are the most frequent pathogens. Often gram-positive rod-shaped bacilli were also found, the pathogenicity of which has been underestimated in the literature up to now. The anaerobes did not play an important role in our patients. The value of gram staining (immediate information and safer antibiotic therapy) is pointed out on the basis of the reported results.

Chronic otitis externa and otitis media treated by total ear canal ablation and ventral bulla osteotomy in thirteen dogs.

Ventral bulla osteotomy was combined with total ear canal ablation for the treatment of chronic otitis externa and otitis media in 13 dogs (14 ears) that had been refractory to medical and surgical treatments. Resolution of disease occurred in 11 dogs (12 ears). One dog with unilateral disease underwent a second operation before achieving a good result. One dog was euthanatized for persistent unilateral disease after three surgical procedures. The recurrence of disease in these two dogs (15%) was associated with remnants of ear canal integument within the osseous horizontal canal or tympanic bulla. Facial paralysis occurred in four dogs (31%) and there were no complications in eight dogs (62%). This technique shows no advantage over lateral bulla osteotomy combined with total ear canal ablation for the treatment of chronic otitis externa and otitis media.

Nasopharyngeal secretory immunoglobulins in children with recurrent acute otitis media and secretory otitis media.

Secretory IgA (SIgA) and secretory IgM (SIgM), total IgA and total IgM were measured in plasma and nasopharyngeal secretions (NPS) from young children with different degrees of otitis proneness. Significantly higher levels of plasma IgM and lower levels of NPS-SIgM were found in children with recurrent episodes of acute otitis media (rAOM) compared with children suffering from secretory otitis media (SOM) and healthy controls. Both plasma IgA and NPS-SIgA were evenly distributed in the three groups of children investigated, and in most children the levels of NPS-SIgA exceeded plasma IgA levels. Plasma SIgA was significantly increased in children with rAOM and SOM, probably resulting from frequent occurrence of inflammatory events at the nasopharyngeal level. No correlation could be demonstrated between NPS-SIgA and plasma IgA, or between NPS-SIgM and plasma IgM. Also, for both NPS-SIgA and NPS-SIgM, there was no correlation with age. A negative correlation was observed between the transudation index of albumin to the nasopharynx and the ratio of NPS-SIgA to total NPS-IgA. A ratio of 1 (100%) corresponded to a transudation index of 8%. The ratios of NPS-SIgA to total NPS-IgA varied considerably and a range of 39%-88% could only to some extent be explained by transudation of plasma IgA to NPS. The results of the present study show that the children with rAOM and SOM are well furnished with locally produced SIgA antibodies at the nasopharyngeal level. In children with SOM, the nasopharyngeal hypofunction in the case of low NPS-SIgM seems to be less pronounced compared with that of otitis-prone children.

Microbiology of recently treated acute otitis media compared with previously untreated acute otitis media.

Isolates were obtained from 169 middle ear aspirates of 148 children with recently treated acute otitis media (RTOM) and from 123 aspirates of 84 children with previously untreated acute otitis media (UOM). In RTOM Streptococcus pneumoniae and Group A streptococcus (P less than 0.02) were recovered less frequently whereas Staphylococcus aureus (P less than 0.001) and Haemophilus influenzae (P less than 0.02) were recovered more frequently than in UOM. Patients with RTOM had more beta-lactamase-producing organisms and multiple isolates. Bilateral sterile aspirates were more common in RTOM although bilateral otitis media was more common in UOM. In RTOM most Branhamella catarrhalis isolates were co-pathogens whereas Staphylococcus epidermidis were always isolated in pure culture. Amoxicillin was the antimicrobial most frequently (83.9%) received for the recently treated episode of otitis media. In RTOM 62.4% of isolates were susceptible to previously prescribed antibiotics, suggesting that factors other than antimicrobial susceptibility are also important in the occurrence of RTOM.

Clinical-histopathological correlations in experimental otitis media: implications for silent otitis media in humans.

Clinical-histopathological correlations were sought in an experimental animal model of otitis media. Among 20 chinchillas inoculated intranasally with wildtype influenza A/Alaska virus (H3N2) and type 7F Streptococcus pneumoniae, 15 animals (18 ears) developed otoscopic and tympanometric signs of otitis media with middle ear effusion. Middle ear inflammation was most intense 10 days after virus inoculation. Twenty-two days after virus inoculation, eight ears showed diffuse middle ear histopathology and contained effusion, which cultured pneumococcus, five ears showed focal histopathology, and four of the five contained no effusion. Clinical manifestations of otitis media had disappeared in four of the 13 ears with pathology at sacrifice; otoscopy was normal in all four ears, tympanometry was normal in three ears, and both otoscopy and tympanometry were normal in one ear. All four of these ears with clinically "silent" middle ear histopathology had shown abnormalities of ear drum appearance or tympanometry between 7 and 14 days after inoculation. Discordance between histopathology and the clinical examination performed at sacrifice was greatest for ears with focal pathology.

Tuberculous otitis media as a secondary infection to chronic otitis media with cholesteatoma.

A series of six cases of tuberculous otitis media is reviewed. All patients had a history of chronic otorrhea and were operated on with a presumptive diagnosis of chronic otitis media with cholesteatoma. Postoperatively the diagnosis of tuberculosis was established by histologic examination of the granulation tissue from the middle ear and mastoid. We believe that any patient with a long history of discharging ears needs histologic examination, as tuberculous otitis might be the cause of infection. We report our findings in these patients and discuss the possibility of penetration of tuberculous mycobacteria into the ear and mastoid. In our opinion, the tuberculosis is secondary to established ear infection.

C1q and C1 subcomponent complexes in otitis-prone and non-otitis-prone children. A prospective study of children during their first years of life.

Children with recurrent acute otitis media (rAOM) often show reduced C1q concentrations and an excess of (C1r-C1s)2 complexes. It is not known if such C1 aberrations precede development of rAOM or are a consequence of the infections. For this reason, serial investigation of C1q and C1 subcomponent complexes from birth until the age of three was performed in 113 children, 13 of whom developed rAOM. C1q concentrations at birth were found to be lower in the rAOM group than in children who did not experience acute otitis media, and were also correlated with age at the time of the first AOM episode. However, the wide variation of C1q within the groups precluded the use of C1q as a predictive marker. Excess (C1r-C1s)2 complexes were consistently absent at birth. High concentrations were found in children with established otitis media and the complexes persisted in association with recurrent disease. In conclusion, the C1 aberrations characteristic of rAOM were mainly acquired as a result of infection.

Medical treatment of chronic otitis media with effusion (secretory otitis media).

To determine whether antimicrobial therapy is of value in the treatment of chronic otitis media with effusion (secretory otitis media), we treated 1,429 4- to 8-year-old children--2224 affected ears--with a fixed regimen of an antibiotic mixture (Pediazole) for 10 days and a decongestant (Novafed) for 30 days. We observed the children monthly to determine the rate of clearance. Validity of diagnosis was greater than 90% with an algorithm of pneumatic otoscopy and tympanometry. Medication compliance was not measured. At 1 month, 45% of the children (48% of the ears) had cleared and at 2 months, 60% of the children (63% of the ears) had cleared. Factors such as sex and prior treatment in the preceding 3 months were no different in the cured vs. the uncured groups. Age significantly influenced the cure rate (P less than 0.0001); the older the child, the higher the clearance rate. Tympanograms type 5, 8, and 12-14 were significantly more prevalent in the uncleared group (P = 0.0001). The clear rate for unilateral cases was 76% and for bilateral cases, 47% (P less than 0.0001). Children with chronic otitis media with effusion are most likely to be cured by medical therapy/time if they are older, have unilateral disease, or a peaked tympanogram. Surgery should be withheld in these children for 2 or more months to permit the highest rate of spontaneous resolution.

Antibody activity before and after pneumococcal vaccination of otitis-prone and non-otitis-prone children.

The antibody activity of the IgM class and subclasses of IgG and IgA against pneumococcal bacteria of types 3, 6A and 19F was studied before and after administration of a pneumococcal vaccine (Pneumovax) in a group of children with recurrent acute otitis media (rAOM) and in groups of non-otitis-prone children. Only occasionally was there a significant rise in antibody activity after vaccination in any of the groups. There was no difference in the response to vaccination between rAOM children and healthy children. However, rAOM children exhibited lower antibody activities in most Ig subclasses against pneumococcus type 6A--a common causative agent in AOM--before as well as after vaccination compared with the healthy children. The results indicate that the response to vaccination is equally poor in all children, irrespective of whether they have a history of frequent attacks of acute otitis media, but, in contrast to healthy children, the rAOM children seem to have an inability to mobilize antibodies in response to infections with some pneumococcal types.

Antimicrobial therapy for otitis media with effusion ('secretory' otitis media).

OBJECTIVE: To determine the effectiveness of antimicrobial treatment for otitis media with effusion ("secretory" otitis media) in children. DATA SOURCE: We report the reexamination of a previously published study by Mandel et al that evaluated the efficacy of a 2-week course of antimicrobials (amoxicillin trihydrate) with and without a 4-week course of an oral decongestant-antihistamine combination in a double-blind, placebo-controlled, randomized trial involving 518 infants and children with otitis media with effusion. DATA SYNTHESIS: At 4 weeks, amoxicillin efficacy as determined by a tympanometric criterion (P = .121) or by a measure of improvement in hearing (P = .311) was insignificant. Only by otoscopic judgment, which is shown to contain a systematic bias as used in this clinical trial, could an argument be made for a marginal efficacy of amoxicillin at the 4-week end point. Logistic regression analyses of the combined effects of treatment and prognostic factors showed no significant differences between placebo- and antibiotic-treated groups for unilateral effusions and for bilateral effusions. When subjects with unilateral and bilateral effusions were combined, the estimated efficacy of antibiotic treatment was 12.3% by otoscopy (P = .014) and 4.8% by tympanometry (P = .171). We also demonstrate the sensitivity of outcome to diagnostic measures used and provide statistical evidence questioning the validity of otoscopic observations in this study. Six weeks after the termination of amoxicillin therapy, the recurrence of effusion was two to six times higher in the amoxicillin-treated children than in those treated with placebo (P = .001), and resolution of effusion was not significantly different among antibiotic and placebo groups (13.6% and 11.3%, respectively; P = .477). CONCLUSIONS: Amoxicillin with and without decongestant-antihistamine combination is not effective for the treatment of persistent asymptomatic middle-ear effusions in infants and children.

[A severe form of external otitis: necrosing diabetic otitis].

Otitis externa are of usual observation in inter-tropical regions. Pseudomonas aeruginosa is responsible generally. But, when immunodeficiency is associated or on diabetic diathesis, such an otitis externa can be extremely dangerous: extensive osteitis of the base of the skull, paralysis of the last pairs of cervical nerves rapidly creeping, built a clinical identity called malignant external otitis, leading to death in 50% of the cases.
