RESUMO
Septic arthritis and spondylodiscitis are relatively rare but severe diseases with increasing incidence. Septic arthritis is an emergency situation with high morbidity (40 %) and fatality rates (11 %). The infection occurs via a hematogenous route by direct inoculation or per continuitatem. Patients with pre-existing destructive joint diseases or under immunosuppressive treatment are particularly at risk. It is mandatory to sample synovial fluid for isolation of the relevant pathogen and quantification of leucocytes before starting antibiotic therapy. In order to preserve the joint, early evacuation of the infected synovial space is necessary. Spondylodiscitis is characterized by infection of the vertebra and neighboring discs mainly via a hematogenous route. Immunosuppressed and older patients are primarily at risk of infection. Back pain represents the main symptom but due to its unspecific character and the frequent absence of fever, diagnosis is often delayed. In Europe Staphylococcus aureus is the most prevalent pathogen, whereas tuberculosis is the most frequent causal agent worldwide. Magnetic resonance imaging (MRI) respresents the method of choice for the radiological diagnostics. In stable patients isolation of the pathogen should be achieved before starting antimicrobial therapy (e.g. blood cultures or tissue samples by computed tomography guided puncture or biopsy). The recommended duration of pathogen-specific antibiotic therapy for native spondylodiscitis is normally 6 weeks.

OBJECTIVE: To determine which prenatal ultrasound findings can predict survival and mental and motor functioning in children with spina bifida. METHODS: Prenatal ultrasound examinations of all liveborn children who were prenatally diagnosed with spina bifida between 1997 and 2002 at the University Medical Centre, Utrecht (n = 41) were retrospectively reviewed for lesion level, head circumference, ventriculomegaly, scoliosis and talipes. These measures were correlated with postnatal anatomical (as assessed by magnetic resonance imaging (MRI)) and functional lesion levels, survival and motor and mental outcome at 5 years of age. The capacity of prenatal ultrasonography to determine lesion level was also assessed in all fetuses diagnosed with spina bifida from 2006-2007 (n = 18). RESULTS: Nineteen infants died before the age of 5 years. Multivariate regression analysis showed that higher lesion level and head circumference > or = the 90th percentile on prenatal ultrasound examination were independent predictors of demise (P < 0.05 and P = 0.01, respectively). None of the ultrasound features was a predictor of motor or mental functioning. Ultrasound predicted anatomical lesion level within one level of the postnatal findings in 50% of the first cohort and 89% of the second cohort (P < 0.01). The level of the anatomical lesion as assessed by postnatal MRI differed from the functional lesion by as many as six vertebral levels. CONCLUSIONS: Lesion level and head circumference on prenatal ultrasound are predictive of survival in children with spina bifida. No predictors were found for mental or motor function at the age of 5 years.

BACKGROUND: The level of physical activity (PA) and the prevalence of depression both change across the lifespan. We examined whether the association between PA and depression is moderated by age. As sense of mastery and functional limitations have been previously associated with low PA and depression in older adults, we also examined whether these are determinants of the differential effect of age on PA and depression. METHODS: 1079 patients with major depressive disorder (aged 18-88 years) were followed-up after two-years; depression diagnosis and severity as well as PA were re-assessed. Linear and logistic regression analyses were used to test reciprocal prospective associations between PA and depression outcomes. In all models the interaction with age was tested. RESULTS: PA at baseline predicted remission of depressive disorder at follow-up (ORâ¯=â¯1.43 [95% CI: 1.07-1.93], pâ¯=â¯.018). This effect was not moderated by age. PA predicted improvement of depression symptom severity in younger (Bâ¯=â¯-2.03; SEâ¯=â¯.88; pâ¯=â¯.022), but not in older adults (Bâ¯=â¯2.24; SEâ¯=â¯1.48; pâ¯=â¯.128) (pâ¯=â¯.015 for the interaction PA by age in the whole sample). The level of PA was relatively stable over time. Depression, sense of mastery and functional limitation were for all ages not associated with PA at follow-up. CONCLUSIONS: Age did not moderate the impact of PA on depressive disorder remission. Only in younger adults, sufficient PA independently predicts improvement of depressive symptom severity after two-year follow-up. Level of PA rarely changed over time, and none of the determinants tested predicted change in PA, independent of age.

BACKGROUND: The carpal tunnel syndrome is one of the most frequent peripheric nerve compression syndromes. Almost 15 years ago, the endoscopic surgery of the carpal tunnel was introduced, in order to reduce postoperative pain and to shorten the length of the postoperative inactivity period, especially work absence. In the literature the rate of complications due to the endoscopic carpal tunnel release surgery is reported differently in respect to number and severity. This paper summarizes all reinterventions after endoscopic surgery in a single specialized hand surgery department, which prefers the open approach even for first time interventions. PATIENTS AND METHOD: A retrospective analysis of all reoperations between 1998 and 2006 is presented. There were 22 reinterventions done on 21 patients. A reoperation was performed if the symptoms of the carpal tunnel syndrome persisted or new pain or sensomotor deficit appeared. There were 8 male and 14 female patients. The age span ranged from 28 to 86 years. The time distance between the first and the second surgery was between 19 days and 36 months. RESULTS: Most of the intraoperative findings were incomplete releases of the retinaculum (n = 13). In three cases abundant adherences caused the clinical symptoms. Three times pathologies were found in carpal tunnel, which could not be recognized or treated endoscopically: severe bleeding in the synovia, massive synovialitis and a swannoma of the median nerve. In seven patients transsected nerves had to be treated: one complete transsection of the median nerve, two nerves with injured radial fascicles, two nerves with violated ulnar fascicles, one neuroma of the median nerve and one transsection of both branches of the ulnar nerve. CONCLUSION: In 22 cases the result of the endoscopic release of the carpal tunnel forced to redo the intervention. In seven patients there were important lesions of the neurovascular structures. Since the long-term result of the endoscopic and open surgery of the carpal tunnel is comparable, it should be discussed if endoscopic surgery is justified even with the risk of mutilant complications and which preoperative imaging procedure is required to discover pathologies and anatomical variants.

Malignant pancreatic tumors in children are rare. The major problem for the clinician is a lack of experience and of accepted therapeutic strategies. Malignant pancreatic tumors in children show a pattern different from that in adults. In infants, especially pancreatoblastomas, solid cystic tumors of females, and endocrine carcinomas of the pancreas must be expected. We report our experience in three patients with malignant pancreatic tumors (one pancreatoblastoma and two malignant endocrine pancreatic carcinomas) and review the present literature with a focus on the typical clinical and biologic features and the presently recommended therapeutic strategies. Pancreatoblastomas and solid cystic tumors are mainly found in the head of the pancreas. Fibrotic capsules with rare, late metastases are characteristics of these tumors, indicating total resection to be an important therapeutic procedure. Pancreatoblastomas should additionally be treated with chemotherapy (ADM, IFO, cis-PL, VP16). Endocrine carcinomas of the pancreas (malignant gastrinomas and malignant insulinomas) should also primarily be treated with radical surgery, including extensive lymph node dissection. In case of distant metastases, local resection (liver) or somatostatin in combination with chemotherapy (streptozocin in the case of malignant insulinomas) may be used.

We show that immunohistochemistry for hMSH2 and hMLH1 is an easy and reproducible routine procedure. The interpretation of the staining results is unequivocal and investigator-independent. It is now necessary to validate the specificity and sensitivity of the method in a multicenter study with tumors of known mutations. As a consequence perhaps MIN testing may be replaced by immunohistochemistry as a first-line pretesting for HNPCC, reducing cost and time required.
