[Fruit and vegetable consumption by children and adolescents in Germany: Results of KiGGS wave 1]. / Obst- und Gemüsekonsum von Kindern und Jugendlichen in Deutschland : Ergebnisse der KiGGS-Welle 1.

BACKGROUND: A high fruit and vegetable intake contributes to a healthy diet, which is very important for the development of children and adolescents. OBJECTIVES: With data from the first follow-up survey of the Child and Adolescent Health Surveys (KiGGS wave 1) the fruit and vegetable intake and its association with determinants are analyzed. METHODS: Via telephone interviews the average numbers of portions of fruits and vegetables consumed by 9,950 girls and boys aged 3-17 years were assessed. In addition, the proportion of persons achieving five portions of fruits and vegetables per day was calculated. The number of portions was analyzed in association with social status, parent's educational level, media consumption, and other determinants via multiple linear regression models. RESULTS: Only 12.2 % of girls and 9.4 % of boys consume the recommended five portions of fruits and vegetables per day. 38.6 % of girls and 33.5 % of boys consume at least three portions per day. On average, girls consume 2.7 and boys 2.4 portions of fruits and vegetables per day. Younger participants consume significantly more portions of fruits than older participants. The percentage of persons consuming five or at least three portions per day increases significantly with higher socioeconomic status, higher parent's educational level, and lower media consumption. Furthermore, children who conduct sport outside of school, those who are physically active every day, and boys living in central Germany consume significantly more portions of fruit and vegetables. CONCLUSION: Most children and adolescents do not consume enough fruits and particularly vegetables. The consumption differs considerably according to socio-demographic background and lifestyle factors, which should be considered in promotional campaigns.

Monaural tinnitus from a contralateral inferior colliculus hemorrhage.

A 48-year-old man presented with sudden right ear tinnitus and showed no other otoneurologic signs or symptoms. Auditory brainstem response revealed prolonged III-V interpeak latencies from stimulating either ear. MRI revealed a small, circumscribed lesion of the left inferior colliculus, probably from an acute hemorrhage leading to a small cavernous malformation. Circumscribed lesions of the inferior colliculus are rare with no prior reports of contralateral tinnitus.

[Retropharyngeal tendinitis--a rare differential diagnosis of retropharyngeal abscess]. / Retropharyngeale Tendinitis--Eine seltene Differenzialdiagnose eines Retropharyngealabszesses.

Because of their similarity, clinical symptoms of a calcific retropharyngeal tendinitis can be misdiagnosed for a retropharyngeal abscess. We present two patients who were admitted for retropharyngeal abscess, however, careful examination revealed amorphous calcification anterior to C1-C2 in addition to prevertebral soft tissue swelling. Knowledge of the characteristic clinical symptoms and the pathognomonic imaging features is crucial to correctly diagnose the disease and to prevent unnecessary tests and treatment.

Non-syndromal round window atresia: an autosomal dominant genetic disorder with variable penetrance?

Round window atresia can be seen in association with syndromal anomalies such as mandibulofacial dysostosis, Mondini type anomalies or cretinism, or with extensive otosclerosis. Non-syndromal round window atresia is extremely rare and until today there is no proof whether non-syndromal round window atresia can be inherited. We present two family members with non-syndromal round window atresia. Based on this case and on an extensive literature review, we discuss the possible ways of sound transmission with round window occlusion as well as the possibility of an autosomal dominant inheritance pattern of these two non-syndromal cases. Evaluating the hearing test results, the effect of round window atresia in non-syndromal cases cannot be thoroughly explained by current theories of sound transmission. In general, full occlusion of the round window should result in a complete air-bone-gap and a surgical procedure to open the window, e.g. a cochlear fenestration which creates a new pressure outlet for the inner ear fluids, should result in normalizing the hearing levels. Astonishingly, patients with non-syndromal round window atresia, show hearing tests similar to those in patients with otosclerosis. In contrast to otosclerosis, complete closure of the air-bone-gap by surgery in patients with round window atresia does not seem to be possible according to currently reported cases. Therefore, routine examination of the round window in stapes surgery should be part of every stapes surgery and a high resolution CT scan should be considered in particular prior to revision of unsuccessful stapes surgery. As a genetic inheritance pattern can be assumed, specific emphasis should also be laid on the patient's family history.

[The interesting case--case no. 59]. / Der interessante Fall Nr. 59. Z. n. endonasler Nassenebenhöhlenoperation einer chronischen Sinusitis maxillaris et ethmoidalis beidseits und Bilaterale chronische sudurale Hämatome.

UNLABELLED: Complications after endoscopic sinus surgery are rare and occur in about 0.5 % of all cases. However postoperative symptoms such as severe cephalgia and nasal discharge of clear fluids indicate a cerebrospinal fluid leakage. CASE: A 64 year-old-patient presented to our clinic four months after an endoscopic sinus surgery complaining of the two above mentioned symptoms for about 4 weeks. In a computed tomography study of the frontobasis there was no evidence of an osseous defect. An MRI of the head revealed a bilateral temporal fluid collection as seen in bilateral chronic subdural hematoma. Therefore the present illness was no consequence of the preceding surgery. CONCLUSION: Significant symptoms of severe postoperative complications after endoscopic sinus surgery can still be misleading. Therefore accurate diagnostic and imaging procedures are always crucial to support the initial diagnosis.

Correcting myopic astigmatism with an areal 193 nm excimer laser ablation.

A new system to correct symmetric bow-tie myopic astigmatism with the excimer laser using oval apertures for toric ablations is described. Initial results in two patients who had -5.0 and -5.5 diopters of astigmatism after surgery with six-months follow-up showed a reduction of up to 85% with a minimal axial error of two degrees.
