[english] Pediatric wrist empyema are very rare, this is the first case report in the current literature describing a hematogenic spreading of bacteria from dental caries, leading to a severe wrist empyema.[german] Kindliche Handgelenksempyeme sind sehr selten. Dies ist in der aktuellen Literatur die Erstbeschreibung einer hämatogenen Streuung von Bakterien aufgrund eines kariotischen Zahnstatus, die zur Ausbildung eines schweren Handgelenkempyems geführt hat.

Constriction ring syndrome is an uncommon deformity with unknown etiology and multiple manifestations. The most common change occurs at the lower extremities. A complete circular amniotic band syndrome of the trunk is an extremely rare condition. There are less than ten other reported cases in the literature. We present a new case of this congenital abnormality, the operation procedure and the results.

Introduction: Extensive burn injury has systemic consequences due to capillary leak. After restoration of cellular integrity, infused fluid volume has to be removed partially. This can provoke electrolyte disorders. Purpose: We investigated the effect of progressive fluid removal on serum sodium level. Method: Retrospective study. Patients admitted to a burn unit were analyzed and separated in two groups without (Group A) or with (Group B) prolonged hypernatremia. Daily infusion-diuresis-ratio (IDR) was analyzed. Results: Fourty (12 female; 28 male) patients with a mean age of 47±19 years, a total burn surface area (TBSA) of 26±12%, and a mean abbreviated burned severity index (ABSI) score of 7.3±2 were included. In Group A 25 patients with a mean age of 47±18 years, a mean TBSA of 23±11%, and a mean ABSI score of 6.9±2.1 were summarized. In Group B 15 patients with a mean age of 47±22 years, a mean TBSA of 30±13%, and a mean ABSI score of 8.1±1.7 were included. Hypernatremia occurred on day 5±1.4. There was no significant difference between both groups for fluid resuscitation amount within the first 24 hours. Statistical analysis of the first 7 days after burn injury showed a significantly higher percentage of removed fluid in Group B for day 3, day 4, day 5, day 6 and day 7. Conclusions: Amount and velocity of fluid removal regimen after burn injury can provoke electrolyte disorders. Serum sodium concentration can be used to calculate need of fluid resuscitation for fluid maintenance. There is a need of an established fluid removal strategy.

Malignant tumors of pediatric hand are very rare. This case report describes an epithelioid sarcoma at the finger of an 11 year old girl and discusses general treatment options in this rare patient population.

Introduction: In-hospital hypernatremia is associated with increased mortality rates. We want to elucidate the impact of in-hospital acquired hypernatremia in mortality of Toxic Epidermal Necrolysis (TEN). Purpose: Is there an association between hypernatremia and mortality in patients with TEN? Method: Retrospective study of 25 patients with TEN. Laboratory electrolyte results, diuresis and survival were analyzed. Patients were separated in two groups without (Group A) or with (Group B) hypernatremia. Results: In Group A 10 patients with a TBSA of 74±25% (mean ± standard deviation), and a SCORTEN-Score of 2.7±0.9 were summarized. Diuresis within the first 10 days after admission was 1±0.3 ml/kg/hour. In Group B 15 patients with a TBSA of 76±19%, and a SCORTEN-Score of 3.5±1 were included. Diuresis within the first 10 days after admission was 1.4±0.4 ml/kg/hour. Hypernatremia occurred on day 3.3±2.4 after admission and persisted for 5.3±2.9 days. Statistical analysis showed a significantly higher diuresis (p=0.007) and SCORTEN-Score (p=0.04) in the hypernatremic patients. One normonatremic and 8 hypernatremic patients died during ICU-stay (overall mortality rate 36%). A significantly higher mortality rate was found in Group B (odds ratio: 13,5; 95% confidence interval: 1.34–135.98; p=0.01) during ICU-stay. Conclusion: TEN patients with an in-hospital acquired hypernatremia have an increased mortality risk. Close electrolyte monitoring is advisable in these patients.

Introduction: In-hospital hypernatremia develops usually iatrogenically from inadequate or inappropriate fluid prescription. In severely burned patient an extensive initial fluid resuscitation is necessary for burn shock survival. After recovering of cellular integrity the circulating volume has to be normalized. Hereby extensive water and electrolyte shifts can provoke hypernatremia. Purpose: Is a hypernatremic state associated with increased mortality? Method: Retrospective study for the incidence of hypernatremia and survival in 40 patients with a totally burned surface area (TBSA) >10%. Age, sex, TBSA, ABSI-Score and fluid resuscitation within the first 24 hours were analyzed. Patients were separated in two groups without (Group A) or with (Group B) hypernatremia. Results: Hypernatremia occurred on day 5±1.4. No significant difference for age, sex, TBSA, ABSI-Score and fluid resuscitation within the first 24 hours were calculated. In Group A all patients survived, while 3 of the hypernatremic patient in Group B died during ICU-stay (Odds-ratio = 1.25; 95% CI 0.971–1.61; p=0.046). Conclusion: Burned patients with an in-hospital acquired hypernatremia have an increased mortality risk. In case of a hypernatremic state early intervention is obligatory. There is a need of a fluid removal strategy in severely burned patient to avoid water imbalance.

Introduction: The skin protects against fluid and electrolyte loss. Burn injury does affect skin integrity and protection against fluid loss is lost. Thus, a systemic dehydration can be provoked by underestimation of fluid loss through burn wounds. Purpose: We wanted to quantify transdermal fluid loss in burn wounds. Method: Retrospective study. 40 patients admitted to a specialized burn unit were analyzed and separated in two groups without (Group A) or with (Group B) hypernatremia. Means of daily infusion-diuresis-ratio (IDR) and the relationship to totally burned surface area (TBSA) were analyzed. Results: In Group A 25 patients with a mean age of 47±18 years, a mean TBSA of 23±11%, and a mean abbreviated burned severity index (ABSI) score of 6.9±2.1 were summarized. In Group B 15 patients with a mean age of 47±22 years, a mean TBSA of 30±13%, and a mean ABSI score of 8.1±1.7 were included. Statistical analysis of the period from day 3 to day 6 showed a significant higher daily IDR-amount in Group A (Group A vs. Group B: 786±1029 ml vs. –181±1021 ml; p

Purpose: In patients with major burn injuries mechanical ventilation is often required for longer periods. Tracheostomy (TS) plays an integral role in airway management. We investigated the effect of TS on ventilation parameters within 8 hours after TS. Materials: A retrospective analysis of severely burned patients admitted to the burn unit of a German University Hospital was performed. Ventilation parameters 8 hours before and after TS were registered. Results: A retrospective analysis of 20 patients which received surgical TS was performed. Mean age was 52±19 years. Mean abbreviated burned severity index (ABSI) was 8.3±2.2. A mechanical ventilation was required for 14.3±4.8 days. TS was performed on day 7±4. Inspiratory oxygen concentration (FiO2) (p
