We measured energy expenditure (MREE) and nitrogen excretion (UUN) in patients with severe head injury randomized to early parenteral (TPN, n = 21) or jejunal (ENT, n = 27) feeding with identical formulations. The MREE rose to 2400 +/- 531 kcal/day in both groups and remained at 135% +/- 26% to 146% +/- 42% of predicted energy expenditure over 4 weeks. Nitrogen excretion peaked the second week at 33.4 +/- 10 (TPN) and 31.2 +/- 7.5 (ENT) g N/day. Both routes were equally effective at meeting nutritional goals (1.2 x MREE, 2.5 g protein/kg/day intake, stabilized albumin and transferrin levels). Infections were equally frequent: 1.86 episodes/TPN patient versus 1.89 episodes/ENT patient. While patient charges were much greater for TPN, the hospital costs were similar for TPN and ENT support regimens. These findings show that patients with head injuries are hypermetabolic for weeks, that only 27% are capable of spontaneously eating nutritional requirements by discharge, and that either TPN or ENT support is equally effective when prescribed according to individual measurements of MREE and nitrogen excretion.

A total of 56 subjects with auricular sinuses were investigated at the ENT clinic of University Kebangsaan Malaysia (UKM) from April 1986 to April 1987. Infection was the main complaint, accounting for 60% of the cases. Chinese formed the majority of the patients (51%) and the commonest age group was between 1 to 10 years. Multiple anomalies were seen more amongst the Indians and none were noted among the Chinese subjects. Hearing loss was noted in 6% of the cases. Only infected cases were operated and none showed recurrence.

Even after a single daily dose of 400 mg, the concentrations of ofloxacin in infected middle ear tissues are within the therapeutic range. Even 20 h after a single dose of 400 mg ofloxacin, the tissue concentrations in cartilage and cholesteatomatous matrix are in excess of the minimal inhibitory concentration for a number of pathogens, such as Staphylococcus aureus and Haemophilus influenzae. The especially high concentrations in middle ear mucosa, auricular cartilage and cholesteatomatous matrix are striking. No complications or side effects were observed during ofloxacin treatment in this study. The study demonstrates that a dose of 400 mg ofloxacin per day is an effective and patient orientated therapeutic regime for the treatment of ENT infections, particularly of ear infections.

The average concentration in 75 female/male patients was 1.90 +/- 1.10/1.55 +/- 0.62 mg/l in serum, 0.81 +/- 0.42/0.74 +/- 0.48 mg/kg in bone, 2.40 +/- 1.16/1.94 +/- 0.87 mg/kg in cartilage, and 2.35 +/- 1.28/1.99 +/- 1.02 mg/kg in mucosa. In each case the highest serum or tissue concentrations were observed 2 hours after the last ofloxacin administration (serum 2.60 +/- 0.41 mg/l, bone 1.10 +/- 0.75 mg/kg, cartilage 3.40 +/- 0.86 mg/kg, mucosa 3.50 +/- 1.05 mg/kg), but even 8 hours after the last dose the levels still exceeded the MIC 90% of e.g. Pseudomonas aeruginosa, Staphylococcus aureus or Haemophilus influenzae. The clinical investigations carried out show that ofloxacin represents a new oral therapeutic agent of significant value in otorhinolaryngology, particularly in the treatment of problematic infections. As the investigations show, the level in healthy tissue is definitely within the therapeutic region for a period of 8 hours. In ENT (nasal and paranasal) infections, ofloxacin should be given for defined indications, e.g. for oral therapy of problematic infections due to P. aeruginosa, and if possible after identification of the pathogen.

The global epidemic of HIV infection remains appalling. By 2001, there were an estimated 1.4 million HIV-infected children, with 4.5 million deaths. In the UK, paediatric cases are clustered around population centres where there are high concentrations of infected immigrant adults, and to a lesser extent, areas where IV drug abuse is common. The highest incidence remains in London and the southeast. With the national redistribution of immigrant and refugee families, any doctor in any specialty may expect to be involved with children who are HIV positive, or have clinical AIDS. The majority of children are infected vertically, i.e. infection of the infant from an infected mother in the pre-, peri-, or post-natal periods. Rates of transmission vary from 15-20% in the developed countries. Children with HIV infection may have their primary presentation to ENT doctors, who should have appropriate thresholds for suspecting the diagnosis. The most common presenting features include persistent generalised lymphadenopathy, hepatosplenomegaly, chronic/recurrent diarrhoea, poor growth, and fever. Fifteen to twenty percent of untreated children will present with an AIDS-defining illness by 12 months, typically with Pneumocystis pneumonia at approximately 3-4 months of age. Seventy percent of perinatally infected children will exhibit some signs or symptoms by 12 months Without treatment, the median age to progression to AIDS is approximately 6 years, and 25-30% will have died by this age. The median age of death is approximately 9 years. Children may also present with repeated/unusual ear infections, sinus disease (inc. mastoiditis), tonsillitis, orbital/peri-orbital cellulitis, oral candidiasis, and dental infections. Infections with streptococcus pneumoniae and group A streptococcus are common, and often progress to severe systemic infection with an appreciable mortality. Infections may be due to unusual pathogens such as Pseudomonas, 'typical' and atypical Mycobacteria, Candida, Aspergillus, etc. Fungal infections of the sinuses (inc. Aspergillus and Rhizopus spp.) may be particularly devastating, with rapid spread to involve bone and the central nervous system. Another classical presentation, which may present to ENT doctors, is that of bilateral parotid enlargement, especially in children who are 'slow progressors', many of whom also have Lymphoid Interstitial Pneumonitis (LIP). A major attitudinal change has occurred due to advances in 3 main areas: (i) the multidisciplinary management of the infected mother (inc. counselling, antenatal screening, elective caesarean section, advising against breast feeding, etc.), (ii) the prevention of vertical transmission, using anti-retroviral therapy to the infected mother during pregnancy, and to the potentially infected infant in the first weeks of life, and (iii) major advances due to the advent of highly active anti-retroviral treatment. With effective use of these measures, transmission rates may be reduced to <2%. None of the measures though, affect a cure, and it will still be many years before the development of effective vaccines. ENT doctors may be referred children already known to be HIV-positive. Knowing how to talk to infected children (and their parents) is full of potential pitfalls, and requires careful forethought. Many infection-control policies have required considerable rethinking due to the AIDS epidemic. This has especially been the case with respect to needle-stick injuries, post-exposure prophylaxis, sterilization and re-use of equipment, and safe approaches to surgery.

Infection is the main factor of morbidity and mortality in children with sickle cell disease (SCD). The objective of this study is to determine it's epidemiologic outline in senegalese children and adolescents with SCD. We retrospectively studied infection data in all the charts of a cohort of 323 patients with SCD (307 SS, 13 SC and 3 s beta + thalassemia) followed at Albert Royer children hospital from january 1991 to december 1997. Serum sampling was systematically made for HIV and antigen HBs serology in all patients we received in the last 3 months (october to december 1997). Patients were aged from 5 months to 22 years (medium age = 8 years). 813 infection episodes were diagnosed, concerning 184 patients (56 per cent). SS patients were more affected (59 per cent) than the others (23 per cent, p = 0.04). ENT and broncho-pulmonary onsets were more frequent but had a generally benign course. Menigitidis, septicemia and osteomyelitis were exclusively diagnosed in SS patients. Their prevalences in this group were respectively: 1.0 per cent, 4.9 per cent and 9.8 per cent. HIV serology was determined in 155 patients, including 41 per cent with blood transfusion antecedents. All tests were negative. HBs antigen was determined in 104 patients and seroprevalence was 7.7 per cent in the whole group and 6.0 per cent in patients with transfusion antecedents and 7.7 per cent for the others. Plasmodium falciparum malaria onset was observed in 9.6 per cent of our patients and there was no case of cerebral malaria. Infection was involved in 9 of the 11 cases of death. Then infection constitute the major problem in children and adolescents with SCD in Dakar. However prevalences of severe onsets are comparable to data in Europe despite our poor follow up conditions. Senegal haplotype may lead to a good tolerance of SCD. Negative HIV serology and low HBs antigen seroprevalence in transfused patients are attributed to a relatively low level of HIV prevalence in the general population and a good transfusion security in Senegal.

Endo larynges tracheal stenoses due to endo luminal or extra luminal processes of benign or malignant character in majority of cases demand the resection of a stenosed part. The use of a stent represents a necessity. In this paper we analyzed 10- year experience of the ENT Clinic of the University Clinical Center Sarajevo regarding the use of stents. 26 patients underwent surgery in a period 1995-2005. Prolonged endo tracheal intubations are encountered as a primary cause of stenoses (73 %). Infection and granulations are noted as a complication in 15,3% of cases. Stent is removed in 16 patients within 3 months and in 7 patients after 12 months.

A 51-year-old woman presented with a sore throat, hoarseness and difficulty in swallowing. On physical examination she was found to have stridor. Laryngoscopy revealed a subglottal stenosis. Infection was thought to be the cause but this was not confirmed by sputum or laryngeal cultures. Because of the clinical course and the presence of antineutrophil cytoplasmic proteinase-3 antibodies, Wegener's granulomatosis was diagnosed. Immunosuppressive therapy led to improvement. At 4-year follow-up the patient had scleritis but no ENT problems. Wegener's granulomatosis should always be considered in a patient with a subglottal stenosis; it can be the first symptom of this disease.

Cervical lymphadenitis is common in childhood and is a frequent source of consultation at the pediatrician's or ENT's office. It is usually caused by a viral upper respiratory tract infection and is self limited. In children with subacute or chronic cervical lymphadenitis which fails to respond to conventional antibiotics, infection due to atypical mycobacteria should always be considered. Infections occur predominantly in an otherwise healthy child of 1 to 5 years of age. The early diagnosis is essential as the treatment of choice is early surgical excision before skin necrosis and fistula occur. This article reviews the specific clinical manifestations, diagnostic tools and treatment of lymphadenitis due to atypical mycobacteria.

Twenty cases which presented with proptosis during the period of 1 year at the Madras Medical College & Govt. General Hospital, Madras, India were taken up for this prospective study. After a detailed ENT and ophthalmological examination, exophthalmometric readings were done on all cases. The etiological causes and other factors were analysed. Malignancies and benign tumours and tumour like lesions were found to be the commonest cause of proptosis. Infections which were once responsible for most cases of proptosis formed only a very small proportion. A person presenting with protosis as the only sign is most likely to suffer from a benign tumour or tumour like lesion while presence of other eye signs should raise the possibility of malignancies. The direction of proptosis was found to be more useful than exophthalmometric readings in determining the site of lesion.
