Safety of electronic molecular resonance adenoidectomy.

Adenoidectomy is one of the most frequent operations in children. In order to reduce hospital stay costs, today, this procedure is performed as day surgery. Even though adenoidectomy is not considered risky, some minor complications may occur, the most important being bleeding (0.5-8% incidence). The surgical technique used can influence considerably postoperative pain and time to recovery. This aspect is essential in the management of day surgery patients, for whom the need of safe and rapid maneuvers associated with early recovery determines the choice of the surgical procedure. Recently, we developed a surgical technique based on the use of an electronic molecular resonance tool associated with bendable suction electrocautery. This study was carried out on 600 patients, divided into two groups, the first undergoing ablation using the molecular resonance tool and the second undergoing curette adenoidectomy. The two groups were homogeneous for age, sex, surgical indications, and grade of adenoid hypertrophy. The following parameters were considered: duration of surgery, importance of intraoperative bleeding, time to cicatrization, incidence of bleeding complications. Duration of surgery and intra- and postoperative bleeding were much lower in the first group than in the group undergoing traditional adenoidectomy. In addition, rhinopharyngeal complete cicatrization, defined as absolute absence of pseudomembrane, was much quicker in the first group, as assessed by postoperative endoscopy. Another major advantage offered by the molecular resonance tool is the accuracy of surgery performed under visual control in a practically bloodless field. To sum up, this method, thanks to its technical features and safety, is particularly indicated in children and in patients with coagulation disorders.

Acute mastoiditis: a 10 year retrospective study.

This retrospective study reviews our experience in the management of acute otomastoiditis over 10 years. During the study period we identified 40 cases in children aged 3 months-15 years with a peak incidence in the second year of life. Sixty per cent of them had a history of acute otitis media (AOM). All the children were already receiving oral antibiotic therapy. Otalgia, fever, poor feeding and vomiting were the most common symptoms, all the children had evidence of retroauricolar inflammation. Computerized tomography (CT) and magnetic resonance imaging (MRI) were used to support the diagnosis and to evaluate possible complications. Streptococcus pneumoniae was the most common isolated bacterium. All the patients received intravenous antibiotics, 65% of children received only medical treatment, 35% also underwent surgical intervention. Mean length of hospital stay was 12.3 days. Cholesteathoma was diagnosed in one child. We conclude from our study that acute otomastoiditis is a disease mainly affecting young children, that develops from AOM resistant to oral antibiotics. Adequate initial management always requires intravenous antibiotics, conservative surgical treatment with miryngotomy is appropriate in children not responding within 48 h from beginning of therapy. Mastoidectomy should be performed in all the patients with acute coalescent mastoiditis or in case of evidence of intracranial complications.

Monothermal air caloric test in children.

We compared the efficacy of bithermal (BAT) and monothermal cold (MCAT) and warm (MWAT) air caloric tests in identifying labyrinthine function anomalies in the child. At first, we established confidence intervals of normality for both monothermal tests in 40 children (22 males, 18 females) aged 6-14 years, clinically healthy and normal as previously shown by BAT. Subsequently, we compared the results of BAT with those of MCAT and MWAT performed in 46 children (22 males, 24 females) aged 6-14 years, affected by multiple labyrinthine diseases. These results confirmed that, as in the adult, MCAT alone should not be used in the evaluation of labyrinthine function in vertiginous patients. As to MWAT, we obtained good sensitivity and specificity with respect to BAT (83% and 90% for 90% probability; 78% and 92.5% for 95% probability). Sensitivity values increased or decreased depending on the disease causing vertiginous symptoms, with decreased or increased number of false negatives. In our opinion, MWAT cannot replace BAT for the study of labyrinthine function in children. MWAT alone can be used when vertigo is ascribable to vestibular neuritis or to endogenous disease (dysmetabolic, dyscrasic, dysendocrine).

Nasal brushing: a clinically useful procedure in pediatric patients with rhinosinusitis?

Sinusitis is a common complication of non-allergic and allergic rhinitis, and can trigger lower respiratory diseases, such as bronchitis and asthma. Standard radiography is unable to give any data about the underlying pathological mechanisms (infectious or allergic) involved and infectious rhinosinusitis is very common in pediatric age, even in allergic patients. We investigated the possibility of obtaining more useful diagnostic information, performing nasal brushing (NB) on 117 children with recurrent respiratory symptoms. The following hypothesis were evaluated: (1) whether NB neutrophil/eosinophil percentages and/or NB culture could predict the radiological evidence of maxillary sinusitis; and (2) whether differences between nonallergic and allergic patients could be detected. In the total patient group and in the nonallergic group, the comparison of NB neutrophil percentages in patients with and without maxillary sinusitis showed a statistically significant difference (median 2 and 18%, respectively; P < 0.001). In the nonallergic group, a NB neutrophil rate > or = 5% was chosen as a cut-off between positive and negative NB diagnosis of rhinosinusitis and NB data were compared with radiological investigations. The results obtained showed that NB was fairly sensitive (91%) and predictive (84%). In allergic patients, neither neutrophil nor eosinophil percentages significantly correlated with the presence of sinusitis. Microbiological studies showed that, even if the presence of bacteria in NB resulted associated with sinusitis, a negative culture was not predictive of the absence of the disease. We therefore suggest that NB describes the present inflammatory status of the upper airways, hence, it is more suitable to describe the inflammation related to ongoing upper respiratory tract infections rather than chronic inflammation due to allergic rhinitis, characterized by relapsing episodes of acute inflammation. In conclusion, we propose to consider NB a reliable tool in the diagnosis of rhinosinusitis, particularly in nonallergic pediatric patients. Compared to standard radiological techniques, NB makes it possible to avoid radiation exposure and gives information about the pathological mechanisms involved in the single patient.

Electronystagmography findings in child unilateral sensorineural hearing loss of probable viral origin.

We studied the labyrinthine function in a group of 72 children aged between 4 and 14 years affected by unilateral sensorineural hearing loss of probable viral origin. From the analysis of the results obtained we confirm the concomitance of cochlear and vestibular damage. However, there were no statistically significant differences between type of audiogram at onset of hearing loss and type of electronystagmography (ENG), while we found a direct correlation between the presence of vertigo or dizziness and type of ENG. Finally hearing recovery was influenced by the presence of vertigo or labyrinthine function alterations. The results of statistical analysis confirmed a significant statistical difference between patients with vertigo or dizziness (V(+)) and those without vertigo (V(-)) and also between patients with ENG 3 (subjects with spontaneous nystagmus or positional nystagmus and canal paresis ipsilateral to the cochlear lesion) and those with ENG 1 (subjects without spontaneous nystagmus or positional nystagmus and with normal vestibular reflex). In fact, hearing recovery was worse in V(+) group and in ENG 3 group.

Plasma and tonsillar tissue pharmacokinetics of teicoplanin following intramuscular administration to children.

The population pharmacokinetics of teicoplanin in plasma and tonsillar tissue in children was determined following intramuscular administration. Thirty seven patients in all received either a single 5 mg/kg dose; 2 doses of 5 mg/kg, 12 h apart; 3 doses of 5 mg/kg, 12 h apart; or, a single 10 mg/kg dose. Limited data, comprising a maximum of 2 blood samples and 1 tonsillar sample were taken from each patient, with the maximum time being 48 h after the first dose of teicoplanin (in the 3 x 5 mg/kg dosing schedule). All plasma data were analyzed simultaneously by a maximum likelihood method employing a modified EM algorithm. A first-order absorption, one-compartment disposition model was fitted to the data. Mean parameter values (with lower and upper 95% confidence intervals) were: clearance/bioavailability, 0.024 L h(-1) kg(-1) (0.020-0.027); volume of distribution/bioavailability, 0.61 L kg(-1) (0.54-0.70); absorption rate constant, 0.43 h(-1) (0.31-0.61). A first-order transfer model for distribution of teicoplanin between plasma and tonsillar tissue was fitted to the tonsil data. The mean parameter values (95% confidence intervals) were: transfer rate constant between plasma and tonsils 0.49 h(-1) (0.35-0.67); transfer rate constant between tonsils and plasma 0.73 h(-1) (0.52-1.03). These rate constants correspond to a distribution half-life of 0.95 h and an equilibrium distribution concentration ratio between tonsillar tissue and plasma of 0.67. After normalising clearance and volume of distribution for body weight, there was no further influence of body weight on the pharmacokinetic parameters. Also, there was no effect of dose, and as two formulations were used, one for the 5 mg/kg dose and the other for the 10 mg/kg dose, no effect of formulation on the pharmacokinetics of teicoplanin after im (intramuscular) administration was found.

Otoneurologic evaluation of child vertigo.

In this study 282 children with vertigo are subdivided (according to previous experiences) into three large groups: (1) vertigo and cochlear diseases; (2) vertigo as an isolated symptom; and (3) vertigo and C.S.N. diseases. Due to the difficult etiopathogenetic investigation of the patients from the second group, the authors focused on that group as they are less studied, are without associated symptoms (deafness--first group; CNS diseases--second group) and where vertigo appears as an idiopathic and an isolated symptom. A careful anamnestic, clinical and instrumental analysis leads to the following observations: (1) in decreasing order of frequency we find the third group, followed by the first and finally by the second; (2) in spite of the overall lower incidence of the second group, this latter includes the paroxismal benign vertigo (PBV) which is overall the second most frequent vertiginous form (after vertigo due to cranial trauma). In this group the authors underline the reasonably high incidence of the iatrogenic syndromes, insisting on the need of their accurate prevention of these risks; (3) the authors confirm that, nowadays, a reliable etiopathogenetic cause of the apparently isolated vertigo (except for the ascertained iatrogenic forms) cannot be identified. Moreover, in spite of its frequency, PBV is the less known form of vertigo, of which we cannot give a certain diagnosis and which can be identified only the the exclusion of all the other known forms through instrumental and clinical observations.

[Therapeutic use of a peptide fraction derived from bovine factor VIII in epistaxis in children].

The results obtained in patients suffering from essential epistaxis in paediatric age using a peptide fraction derived from the enzymatic hydrolysis of bovine factor VIII (VUEFFE-Baldacci) are reported. Carbazochrome sodium sulphate was employed for comparison purposes. Vueffe is effective in reducing haemorrhagic episodes without modifying the laboratory parameters investigated.

The branchio-oto-renal syndrome (report of two family groups).

The major features of the Branchio-Oto-Renal syndrome (BOR syndrome), an autosomal dominant disorder, are branchial remnants, ear anomalies, deafness and renal dysplasia. We report two family groups affected by the BOR syndrome: in two-thirds of the affected children renal abnormalities led to severe renal insufficiency in early life. The necessity for a meticulous search for renal anomalies in individuals with aural and/or branchial abnormalities is emphasized. In affected families, genetic counselling is suggested.

Comparison of cefatrizine and erythromycin for pediatric ear, nose, and throat infections.

A comparison was made of cefatrizine in dosages of 75 mg/kg/day administered once daily or twice daily and erythromycin in a mean daily dosage of 50 mg/kg given in three divided doses for the treatment of acute infections of the ear, nose, and throat in children. Temperature was recorded twice a day during therapy. At the end of treatment, a clinical evaluation of cure, improvement, or failure was made, based on defervescence and abatement of symptoms. All ten children given cefatrizine once daily were cured (P less than or equal to 0.05), as were eight of ten given cefatrizine twice daily and four of ten given erythromycin. The remaining eight patients were improved. One patient given cefatrizine had diarrhea, which appeared on the fifth day of treatment. No other side effects were observed. Cefatrizine appeared to be similarly effective whether given once a day or twice a day; further trials are warranted to confirm the efficacy of once-daily treatment with this cephalosporin.
