[Evoked potentials in Chiari-malformation type I with syringomyelia--a case history].

The Chiari-syndrome Type I being a malformation of the posterior cranial fossa often leads to syringomyelia. The disease becomes apparent in adolescence with kyphoscoliosis, headache, vertigo, ataxy, hearing loss, partial paralysis and other neurological disorders. The onset is typically characterized by dissociated anesthesia, due to the frequent localization of the syrinx in the neighborhood of the posterior column of the spinal cord. It is reported a case of an 15-years-old-girl suffering from intensive headache, recurrent left-sided paresthesias and progredient scoliosis. Somatosensory evoked potentials of left ulnar and tibial nerves revealed a complete loss of cortical response. Diagnostic imaging showed an Chiari-malformation I with herniation of cerebellar tonsils and secondary syringomyelia of the cervical spinal cord. After surgical treatment with posterior fossa decompression, C1 laminectomy and partial excision of cerebellar tonsils the patient had a clear improvement in symptoms. Postsurgical the width of cervical syrinx decreases. Now somatosensory evoked potentials of the left ulnar and tibial nerves show amplitude-reduced cortical responses with a normal latency.

Chlamydophila pneumoniae respiratory tract infection aggravates therapy refractory bronchitis or pneumonia in childhood.

BACKGROUND: Chlamydophila pneumoniae was frequently found in bronchial secretions of children with therapy-refractory bronchitis or pneumonia. It was studied, how the agent modifies the course of disease and what findings are associated with the infection. PATIENTS AND METHODS: Bronchial secretions obtained at bronchoscopy of 428 children were studied for C. pneumoniae infection using polymerase chain reaction with enzyme immunoassay detection. Children tested negative and positive were compared for their clinical findings. RESULTS: C. pneumoniae was found in 143 children (33 %). A C. pneumoniae infection has been found to be associated with a purulent bronchial inflammation (90/143 vs. 144/285, p = 0.02), a Streptococcus pneumoniae co-infection (13/143 vs. 6/285, p = 0.002) and a restrictive disturbance (11/51 vs. 8/93, p = 0.04). Purulent inflammation (Odds ratio 7.9; 95 % confidence interval [CI] 1.6-39.3), 2 co-infections (Odds ratio 14.3; 95 % CI 1.4-144.4) and co-infection with M. pneumoniae (4/4 versus 9/26, p = 0.03; Mantel Haentzel 3.0; 95 % CI 1.1-8.0) were identified as factors more often associated with a restrictive disturbance in children with bronchial C. pneumoniae infection. An adequate antibiotic therapy improved pulmonary function. No association was found for wheezing, eosinophil inflammation of the nasal mucosa, alpha-1 antitrypsin or immunoglobulin deficiency in serum, level of secretory IgA in bronchial mucus, pathological lung scintigram, gastro-esophageal reflux disease, sweat test and other co-infections. CONCLUSIONS: In children with therapy-refractory bronchitis or pneumonia bronchial C. pneumoniae infection was associated with a more severe disease in case of several, mostly bacterial co-infections. Adequate antibiotic therapy for C. pneumoniae infection has been demonstrated to improve pulmonary function.

Maffucci's syndrome as cause of chronic liquorrhea.

We present the case of a 14-year-old girl suffering from Maffucci's syndrome, a rare ailment belonging to the group of osteochondrodysplasias. At the age of 6 months, a diffuse swelling first appeared in the girl's right cheekbone region and the periauricular area. Because of recurrent meningitis with massive otoliquorrhea, several surgical revisions were performed, beginning at the age of 4 years. The histological and immunohistochemical diagnosis showed hemangioma and lymphangioma with enchondroma. As a peculiarity of our patient's diagnosis, we found multiple bone defects apparently caused by venous and lymphomatous angiomatosis. There was also enchondromatosis of the skull base and the upper cervical vertebrae, which caused the recurrent otoliquorrhea and rhinoliquorrhea. A fistula closure was undertaken through a retromastoidal, suboccipital approach and fascial graft of the posterior cranial fossa.
