From 1974 to 1990, 336 Bacteroides isolates were obtained from 312 specimens from 274 patients. They comprised 180 (54%) B. fragilis isolates, 55 (16%) B. theta-iotaomicron, 36 (11%) B. vulgatus, 34 (10%) B. distasonis, 21 (6%) B. ovatus and 10 (3%) B. uniformis. Infections in 253 (92%) patients were polymicrobial, but in 21 (8%) children, a Bacteroides sp. was isolated in pure culture. Most Bacteroides isolates were from peritoneal fluid (114), abscesses (110), wound infections (20), blood cultures (10) and from patients with pneumonia (14) or
chronic otitis media
(8). Predisposing conditions were present in 145 (53%) children; these were previous surgery (46), trauma (28), malignancy (21), prematurity (19),
immunodeficiency
(18), steroid therapy (12) foreign body (10), diabetes (9) and sickle cell disease (7). The micro-organisms isolated most commonly mixed with Bacteroides spp. were anaerobic cocci (221), Escherichia coli (122), Fusobacterium spp. (38) and Clostridium spp. (30). All patients received antimicrobial therapy in conjunction with surgical drainage or correction of pathology in 197 (72%) cases. All but 12 (5%) patients recovered. These data illustrate the importance of Bacteroides spp. in infections in children.

A survey of the isolation of Clostridium spp. from 1543 specimens sent to anaerobic microbiology laboratories revealed 113 isolates from 107 specimens (7.0% of all specimens) from 96 children. The isolates comprised 43 (38%) unidentified Clostridium spp., 37 (33%) C. perfringens, 13 (12%) C. ramosum, five (4%) C. innocuum, six (5%) C. botulinum, three (3%) C. difficile, two (2%) C. butyricum, and one isolate each of C. bifermentans, C. clostridiiforme, C. limosum and C. paraputrificum. Most clostridial isolates were from abscesses (38), peritonitis (26), bacteraemia (10), and
chronic otitis media
(7). Predisposing or underlying conditions were present in 31 (32%) cases. These were
immunodeficiency
(12), malignancy (9), diabetes (7), trauma (7), presence of a foreign body (6) and previous surgery (6). The clostridia were the only bacterial isolates in 14 (15%) cases; 82 (85%) cases had mixed infection. The species most commonly isolated with clostridia were anaerobic cocci (57); Bacteroides spp. (B. fragilis group) (50), Escherichia coli (22), pigmented Prevotella or Porphyromonas spp. (18) and Fusobacterium spp. (10). Most Bacteroides and Escherichia coli isolates with clostridia were from abdominal infections and skin and soft tissue infections adjacent to the rectal area; most pigmented Prevotella and Porphyromonas isolates were from oropharyngeal, pulmonary, and head and neck sites. Antimicrobial therapy was given to all patients, in conjunction with surgical drainage in 34 (35%). Only two patients died. These data illustrate the importance of Clostridium spp. in paediatric infections.

A total of 243 strains of Fusobacteria species was recovered from 226 of 1399 (16%) specimens obtained from 213 children. The strains included 65 (27%) Fusobacterium sp., 144 (59%) Fusobacterium nucleatum, 25 (10%) Fusobacterium necrophorum, five (2%) Fusobacterium varium, three (1%) Fusobacterium mortiferum, and one (0.4%) Fusobacterium gonidiaformans. Most Fusobacteria species were recovered from patients with abscesses (100), aspiration pneumonia (24), paronychia (15), bites (14), chronic sinusitis (ten),
chronic otitis media
(nine), and osteomyelitis (eight). Predisposing conditions were noted in 32 (15%) of the cases. These included
immunodeficiency
in nine (4%), steroid therapy in eight (4%), previous surgery in six (3%), diabetes in six (3%) and malignant neoplasms in five (2%). Fusobacteria sp. was the only isolate in 16 (8%) instances while mixed infections were encountered in 197 (92%) patients. The organisms most commonly isolated with Fusobacteria sp. were anaerobic cocci (155), pigmented Prevotella sp. and Porphyromonas sp. (95), Bacteroides fragilis group (80), Escherichia coli (43) and Bacteroides sp. (39). Most strains of B. fragilis group and E. coli were recovered from intra-abdominal infections and skin and soft tissue infections proximal to the rectal area. Most pigmented Prevotella sp. and Porphyromonas sp. were recovered from oropharyngeal and pulmonary sites and from sites around the head and neck. Antimicrobial therapy was administered to all patients; surgical drainage was performed in 85 (40%). All patients, except two who died, recovered. These findings illustrate the prevalence of Fusobacteria sp. associated with infections in children.

Human
immunodeficiency
virus (HIV), the causative agent of acquired immunodeficiency syndrome (AIDS), has reached worldwide epidemic proportions and is increasing. Otologists, neurotologists, and audiologists practicing in metropolitan centers in North America can expect to encounter patients with HIV-related illnesses, including patients with AIDS-related complex (ARC) and AIDS. Five representative cases are presented:
chronic otitis media
, facial palsy, Gradenigo's syndrome with facial paralysis, otosyphilis, and Kaposi sarcoma of the mastoid. The common link in all cases was HIV infection. This presentation discusses the management of several HIV-infected patients with otologic and neurotologic findings. HIV infection has extended to all parts of North America. The worldwide incidence is increasing. As the epidemic continues to unfold, new challenges to both the diagnosis and treatment of otologic and neurotologic disease in HIV-positive patients will confront the audiologist and otolaryngologist. Recommendations for the safety of the examining audiologist and treating physician are given.

From 1974 to 1994, 2033 microbiological specimens from children were submitted for cultures for anaerobic bacteria. Fifty-seven isolates of Bifidobacterium spp. were obtained from 55 (3%) children, 67 isolates of Eubacterium spp. from 65 (3%) children and 41 isolates of Lactobacillus spp. from 40 (2%) children. Most Bifidobacterium isolates were from
chronic otitis media
, abscesses, peritonitis, aspiration pneumonia and paronychia. Most Eubacterium isolates were from abscesses, peritonitis, decubitus ulcers and bites. Lactobacillus spp. were mainly isolated from abscesses, aspiration pneumonia, bacteraemia and conjunctivitis. Most (> 90%) infections from which these species were isolated were polymicrobial and yielded a mixture of aerobic and anaerobic bacteria. The organisms most commonly isolated with the non-sporing anaerobic gram-positive rods were Peptostreptococcus spp., Bacteroides spp., pigmented Prevotella and Porphyromonas spp., Fusobacterium spp., Staphylococcus aureus and Escherichia coli. Most Bacteroides spp. and E. coli were isolated from intra-abdominal infection and skin and soft tissue infection around the rectal area, whereas most Prevotella, Porphyromonas and Fusobacterium isolates were from oropharyngeal, pulmonary and head and neck sites. The predisposing conditions associated with the isolation of non-sporing anaerobic gram-positive rods were previous surgery, malignancy, steroid therapy and
immunodeficiency
. Antimicrobial therapy was given to 149 (83%) of the 160 patients, in conjunction with surgical drainage or correction of pathology in 89 (56%).

Immunohistochemical analyses were conducted on archival celloidin-embedded human temporal bone sections from an 8-month-old boy with
chronic otitis media
and DiGeorge syndrome. We employed antigen retrieval methods with saturated sodium hydroxide-methanol solution, microwave incubation, and proteolytic treatment to demonstrate the distribution of T-lymphocytes, B-lymphocytes, macrophages, and intercellular adhesion molecule 1 (ICAM-1) expression in the middle ear. B-lymphocytes and macrophages were observed predominantly within the middle ear mucosa. T-lymphocytes were rare. Further, ICAM-1 was expressed in the vascular endothelium of the lamina propria, as well as infiltrating mononuclear cells. This suggests that the expression of ICAM-1 can be induced in the middle ear with otitis media, even if T-lymphocytes are depressed in a cell-mediated
immunodeficiency
disorder such as DiGeorge syndrome.

In order to determine the clinical and laboratory features of X-linked agammaglobulinemia, the records of 33 male patients with XLA were reviewed during 22 years (1980-2002) in the Iranian referral center of primary
immunodeficiency
disorders. The patients' ages ranged from 20 to 360 months (median 113 months). The median age at the onset of the disease was 8 months and the median age of diagnosis was 48 months, with a median diagnosis delay of 33 months. Almost all of the patients presented common infectious diseases, which were: pneumonia, otitis, diarrhea, sinusitis, and arthritis. During the course of illness, infections in the respiratory tract, gastrointestinal tract, central nervous system, and musculoskeletal system were seen in 93.9%, 75.8%, 33.3%, and 21.2% of XLA patients, respectively. The most common complications of these patients were chronic infections in 75.8% of them, including:
chronic otitis media
, chronic sinusitis, chronic diarrhea, and bronchiectasis.

The main clinical presentation of patients with primary antibody deficiency (PAD) incorporates upper respiratory tract infections comprising otitis media, sinusitis and pneumonia. This study was designed to investigate clinical and paraclinical otological complications in major types of PAD. A cross sectional study was conducted on 55 PAD patients with diagnosis of selective IgA deficiency, common variable
immunodeficiency
(CVID), X-linked agammaglobulinemia (XLA), and hyper IgM syndrome. All patients underwent otological examinations, audiometry, and auditory brain stem response. Otological complications were detected in 54.5% of PAD patients. Conductive hearing loss was the main finding amongst PID patients (73.3%) followed by sensorineural hearing loss which was present in 8 cases. Otitis media with effusion (21.8%),
chronic otitis media
(27.2%), tympanosclerosis with intact tympanic membrane (5.4%) and auditory neuropathy (3.6%) were most important found complications. CVID and XLA patients with prophylactic usage of antibiotics had lower rate of audiological complications (p=0.04) and otitis media with effusion (p=0.027). As our results showed, asymptomatic otological findings were not rare in PAD patients; therefore, a systematic otological investigation is recommended as an integral part of the management and follow-up of these patients.
