The efficacy and tolerance of the new oral cephalosporin cefaclor was tested in 61 patients treated for a variety of moderate to severe ENT infections which were not expected to undergo a spontaneous remission without antibacterial therapy. The most frequently isolated pathogens were streptococci and Staphylococcus aureus. The dosage consisted of 500 mg cefaclor three times daily, and the treatment lasted between 4 and 43 days (average 14 days). In 35 cases, some of whom had already been treated unsuccussfully with another antibiotic, the results were very good. In 22 patients locally applied medicaments or surgery contributed to the good result. In four patients an unequivocal evaluation was not possible or therapy was not successful. The frequently noted rapid response to treatment with cefaclor was impressive. No relapses were recorded. In pharmacokinetic studies a cefaclor concentration of 2.8 mcg/g was obtained in the tonsils 90 minutes after oral administration of 1000 mg. Clinical examinations in 61 patients and a complete range of laboratory tests in 47 patients did not reveal any case of allergic reaction. One patient only complained of nausea and diarrhoea. In two patients temporary low grade thrombopenia and thrombocytosis respectively were observed. In several patients a slight transitory rise in transaminases was seen. Cefaclor thus proved to be an effective and well-tolerated antibiotic. Its indications in the treatment of ENT infections are discussed.

Infection from human immunodeficiency virus (HIV) is well known for the particular host susceptibility to a variety of opportunistic infections and unusual malignant neoplasms. Although no tumor develops exclusively in concomitance with HIV infection, malignancies in these patients have different clinical behaviour, response to treatment and prognosis than the pattern observed in HIV negative hosts. Kaposi's sarcoma (EKS) and non-Hodgkin's lymphoma (NHL) are tumors per se diagnostic of AIDS in patients with HIV infection. From 1987 to 1991, 210 HIV positive patients underwent ENT examination without symptom-related selection: 128 were intravenous drug users, 50 homosexual males, 22 heterosexuals, 4 intravenous male homosexual drug users, 3 blood recipients and 3 subjects without known risk factors. Sixteen were allocated in group II, 37 in III, 9 in IV A, 2 in IV B, 31 in IV C1, 37 in IV C2, 48 in IV D and 30 in IV E. Fourteen had head and neck EKS localization. All were males, with a median age of 40 of which 11/14 were homosexuals. The concomitant involvement of skin and mucosa was the most common manifestation and the palate was the most frequently affected mucosal site. Twenty-four had NHL localized within the head and neck: 21 males and 4 females with a average age of 38, 10 intravenous drug users, 9 homosexual males, 3 heterosexuals, 1 blood recipient, 1 subject without known risk factors. Extranodal localization was the most frequent characteristic while the gums were the most commonly involved site. The main characteristics of head and neck manifestations of EKS and NHL are reported with references to literature. The majority of HIV infected patients with EKS or NHL have ENT localizations, perhaps because lymphatic tissue, a HIV target, is well represented in this area and contamination by infectious agents (such as Epstein-Barr virus and cytomegalovirus, probably involved in the pathogenesis of EKS and NHL) can easily occur in the head and neck. The otolaryngologist should be aware of the various, and sometimes misleading, characteristics of these diseases.

The purpose of this research study was to determine whether the clean technique of tracheotomy care is the same, or more, secure from the aseptic, by testing the difference in the level of postoperative pulmonary infection between tracheotomized patients receiving aseptic and those receiving clean tracheotomy care. The sample consisted of 103 patients with tracheotomy (transient or permanent) from ENT or IC units of four big hospitals of Athens. The level of the patient's pulmonary infection was defined using the Weighted Level of Pulmonary Infection Tool, which was constructed especially for this research study. The data were analysed using the x2 statistical test, and the coefficients phi, Cramer's V and Kendall's, while, with the same statistics, the relationship between certain important external variables and the dependent variable was examined. The findings indicated that no statistically significant difference exists between clean and aseptic technique as to the level of pulmonary infection when used for tracheotomy postoperative care of tracheotomized patients.

2 g ampicillin and 1 g sulbactam were given by infusion to 24 patients who were to be operated on in the ENT region. About 1 hour later during the operation samples of serum and of various tissues were taken and analysed for ampicillin and sulbactam. The mean serum concentrations of ampicillin and sulbactam were 59.2 mg/l and 31.6 mg/l, respectively. At the same time the concentrations of the two drugs were usually lower in the tissues than in serum. About 1 hour after the infusion the mean tissue concentration of ampicillin was 33.5 mg/kg and of sulbactam 19.5 mg/kg. The results show that ampicillin and sulbactam penetrate within an hour into the different tissues affected by the operation and maintain about the same ratio as in serum (2:1). The concentrations of ampicillin and sulbactam measured in the different compartments are capable of inhibiting the bacteria most frequently involved in ENT infections. These measurements unequivocally support the use of the ampicillin/sulbactam combination in the treatment and perioperative prophylaxis of bacterial infections of the ENT tract.

The clinical efficacy and tolerance of cefixime were evaluated in an open uncontrolled clinical trial including 37 patients suffering from ENT-infections. The MIC90 values of this new oral cephalosporin against gram-negative pathogens are less than 1 mg/l. The antibacterial activity of cefixime against gram-negative pathogens is stronger than that of other oral cephalosporins. Cefixime was administered for five to twelve days twice daily in a dose of 200 mg. In one patient the treatment with cefixime was discontinued after five days due to perioral dermatitis. In 33 of 36 patients cure or distinct improvement was observed after cefixime treatment, showing a clinical success rate of 91.7%. Causative organisms were isolated in 17 of 37 patients (47.2%). After the cefixime therapy the causative organisms were eradicated in 13 of 17 patients (76.5%). The tolerance of cefixime is comparable with that of other oral cephalosporins.

The recurrent and severe infections of the ENT region during childhood are frequently related to cranio-facial malformations or/and deficiency of the immune system. The cranio-facial abnormalities are at risk to be complicated by transmission deafness either primary or secondary through recurrent middle ear infections. In our pediatric out-patient clinic, most of the patients suffering severe recurrent ENT problems show variable malformations: abnormal implantation or shape of the external ear, a microretrognathism, cervical or facial branchial fistulae, high or ogival palate with anomalies of the dental occlusion or a bifid uvula. All these abnormalities share their origins in a pathological development of the first branchial arch. These developmental anomalies may directly lead to deafness (especially due to an abnormal middle car ossicular development since they are derived in part from the first arch). They may also favor secondary pathologies (middle ear otitis, abnormal soft palate). Moreover the development of the immune system is also dependent of a normal function of the endoblastic epithelium of the pharyngeal pouches which is a part of the branchial system. Immune dysfunctions may therefore accentuate the severity of the ENT Infections.

Over the last 3 years, 403 patients operated in the Department of Cardiovascular Surgery of Broussais Hospital have been transferred to a Department of Internal Medicine for secondary postoperative care. A total of 245 non-cardiac complications (64%) and 134 cardiac or vascular complications (36%) were observed in 321 of these 403 patients (80%). Infections accounted for 26% of non-cardiac complications (63/245). They included 9 cases of mediastinitis, 2 cases of septicemia, 6 endocarditis, 6 wound infections, and 40 other infections (ENT, gastrointestinal, pulmonary, urogenital). The non-cardiac, non-infectious complications comprised mainly delayed healing (39 cases) and pleuropulmonary (29 cases), ENT (9 cases), gastrointestinal (31 cases), urogenital (12 cases), hematological (17 cases) and neuropsychiatric (9 cases) complications; and, finally, 37 inflammatory syndromes. The cardiac complications were pericarditis with or without tamponade (24 cases), arrhythmias or conduction disturbances (50 cases), haemodynamic (54 cases) and vascular (6 cases complications. These very varied complications sometimes occurred late and could be latent. They resulted in prolongation of the duration of hospitalization, so increasing the overall health costs.

Three hundred and one patients with maxillary sinusitis participated in a double-blind, randomized study at 11 ENT-clinics in Europe. Sinusitis was diagnosed by the presence of at least two signs and symptoms and sinus X-ray showing more than 6 mm swelling of the maxillary mucosa. A microbiological specimen was obtained by intrasinusal aspiration. The patients were randomly assigned to treatment either with bacampillin 800 mg b. i. d. or with amoxicillin 500 mg t. i. d. for ten days. The most frequently isolated bacteria were Haemophilus influenzae (94 strains), Streptococcus pneumoniae (66 strains) and Branhamella catarrhalis (12 strains). In 96 of the patients, no microorganisms could be isolated. Beta-lactamase production was found in one H. influenzae strain and in three B. catarrhalis strains. Two hundred and seventy-one patients could be evaluated for efficacy at the follow-up visit day 8-25. The overall clinical outcome was the same in both treatment groups. Adverse events such as skin reactions and upper and lower gastrointestinal reactions occurred in 17.4% of the amoxicillin treated patients and in 10.8% of the bacampicillin treated patients (p = 0.101).

As reported in the literature and observed in clinical practice, a variety of tracheotomy care procedures (tracheotomy suctioning and cleaning techniques) are currently used. The purpose of this research was to determine if clean tracheotomy care was more effective than sterile as measured by levels of postoperative pulmonary infection. Ten hospitals with large Head and Neck/ENT services were selected as data collection sites. At these centers a minimum of 15 tracheostomy patient charts were reviewed pre- and postoperatively for clinical and laboratory data related to infection. Patient level of infection was defined using the Weighted Level of Pulmonary Infection Tool, which was constructed for this study. Three categories of aseptic type emerged (clean, sterile, and mixed) because existing tracheotomy care procedures did not fall into one of the two hypothesized types. Data were analyzed using a maximum likelihood approach to mixed model analysis of variance or covariance. The findings indicated significant differences among the three procedures with laboratory, but not clinical, data. Laboratory data supported practicing clean procedures as those associated with the least postoperative infection.

A questionnaire survey of 225 general practitioners was carried out to establish the proportion of their workload formed by paediatric ENT problems. Approximately 50% of children seeking medical care from their general practitioners had problems in this area. Infections of the upper respiratory tract and associated organs were the most commonly dealt with complaints. The monthly referral rate by GPs of paediatric patients in their practice to an ENT outpatient clinic was 4.3%. As ENT problems are seen so commonly in general practice it is important that teaching of otolaryngology at undergraduate and postgraduate levels is emphasised. We examined the present teaching structure of ENT in Irish universities and established that the appointment of a professorial unit dramatically improved the extent of the undergraduate curriculum. Non-specialist postgraduate ENT exposure was found to be inadequate and a number of mechanisms to improve postgraduate ENT training for GPs are suggested.
