[Mechanisms of injuries of cut and stab wounds of the neck].
The following paper presents a fundamental overview of the relationship between the manner in which cut or stab wound of the neck is inflicted and the resulting injury. The dependence of the type and shape of the weapon is discussed as well as the direction of the thrust. In addition, the main differences between cut and stab injuries and the differences between suicide and murder are pointed out.

[Hearing screening in neonates and infants using brain stem evoked acoustic potentials].
Reported failure rates of screening using the conventional brainstem auditory response (BAER), audiometry range from 5% to 60% with about 30% of the babies having normal hearing sensitivity on follow-up. The results of testing by an automated infant screener using advanced evoked response technology are compared with those of a conventional evoked response system operated by skilled personnel. 50 newborn were tested at a gestational age of 40-42 weeks. Normal results were obtained in all 25 newborn (50 ears) of the control group using both testing procedures. Out of 25 newborn (50 ears) at risk for congenital perinatal or postnatal hearing disorder, abnormal results for either screening or conventional BAER recording were seen in 6 ears with both methods.

Review[Treatment of pain in advanced tumors in the area of the head and neck].
Different mechanisms of pain development and strategies of pain treatment are briefly described as an introduction. Since medicaments are preferentially used for the treatment of cancer pain, pharmacology of analgesics and principles of analgetic therapy are pointed out in more detail. Based on own experiences, a stepwise schedule for the treatment of pain in patients with advanced head and neck cancer is presented.

Since we know that maturation of the hearing system occurs within the first few weeks after birth, audiologic testing should be performed as soon as possible whenever there is the slightest suspicion of a hearing disorder. The only reliable test method in this early period of life is the electric response audiometry. ⋯ The most important of these are: 1. good sedation, 2. sufficient test routine comprising not only clicks but also 500 Hz pulses and bone-conducted stimuli, and 3. sufficient experience in the interpretation of the various recorded response patterns. Comparing subjective and objective results in 533 children, the ERA proves to be the more reliable and effective method giving extensive information on the hearing threshold and the dynamic response of audition and allowing an exact control and correction of the hearing aid adjustment.

This study reports on an immunohistochemical examination of the tonsils. For this purpose 10 clinically healthy tonsils, 15 with acute tonsillitis, 40 with chronic cryptic tonsillitis and 16 hyperplastic tonsils were studied by means of the direct immunofluorescent technique. ⋯ In the extrafollicular area the fluorescent immunocytes were significantly increased. Although we did not notice differences in the density of IgA and IgM immunocytes between chronic cryptic tonsillitis and hyperplastic tonsils in the acute tonsillitis IgA immunocytes were found to be increased.
