[Helicobacter pylori infections in children].

In our patient population with chronic aspecific abdominal complaints Helicobacter pylori gastritis is no rarity. This entity has been diagnosed in 10 children out of 48 (mean age: 8 years 11 months) who underwent an endoscopy of the upper gastrointestinal tract. After treatment with amoxicillin and colloidal bismuth subcitrate during a period of 2 weeks the complaints disappeared and an eradication was obtained in 7. Histology of the antral mucosa demonstrated a type B chronic active gastritis in all patients. A Helicobacter pylori specific serology was positive in all 10 patients. This test was also positive in 17 out of 35 asymptomatic first degree family members; this is an illustration for the high family prevalence of Helicobacter pylori.

Lack of ciprofloxacin ototoxicity after repeated ototopical application.

The possible side effects of ototopically applied ciprofloxacin on inner ear function were investigated. The hearing function of pigmented guinea pigs was evaluated by daily frequency-specific evoked response audiometry after repeated application of the drug to both ears. Ciprofloxacin appeared to have no statistically significant effect on the hearing thresholds of the experimental animals.

Acoustic simulation experiments with preprocessed speech for an 8-channel cochlear implant.

A speech processor for simulation of preprocessed speech in cochlear implantation has been developed. An acoustic simulation of spectrally reduced speech was presented to 169 normally hearing subjects. Several perceptual tests with 9 different filter conditions were carried out. The intelligibility of sentences and the discrimination of phonemes in nonsense syllables were measured. It was established that even within one test session, an important learning effect occurred.

Information transmission with an eight channel bipolar cochlear implant. Acoustic simulation experiments.

In order to find the best stimulus parameters for the processing of a speech signal for cochlear implant applications, a speech processor was developed. The information which can be transmitted by means of an eight channel implant is simulated. The results indicate that identification and forced choice discrimination of (CV) and (VC) syllables is possible. The perception of consonants is more affected than that of vowels. Within one test session an effect of learning was established which remained restricted to the trained filter condition.

The UIA-KUL cochlear implant. Goals and status praesens.

The authors describe the characteristics and specific advantages of their 8 channel bipolar intrascalar stimulator, its main asset being flexibility. They emphasize the need for caution in the use of cochlear implants in children.

Ultrasonography of liver haemangioma. A report of 35 patients totalizing 53 lesions.

During the last two years a total of 53 liver angiomas in 35 patients were examined by sonography. The angiomatous nature of these lesions was proven by angiography, CT, laparotomy, laparoscopy or autopsy. In this material the most striking sonographic data are the reflective character of the angiomas (94%), the subcapsular location (70%), the small size under 2 cm. (32%) and the multiplicity (35%). 90% of the lesions larger than 3 cm. tend to display polylobular contours.
