RESUMO

AIM: To assess whether patients born with an abdominal wall defect (AWD) have impaired cardiorespiratory performance capacity, motor skills, core stability or quality of life in a long-term follow up. METHODS: Patients diagnosed with AWD between 2002 and 2013 were invited to participate in the study, which included clinical examination, spirometry, cardiopulmonary exercise performance testing, assessment of motor activity, ultrasound, electromyography of the abdominal wall and assessment of the Gastrointestinal Quality of Life Index (GIQLI). The results were compared to a healthy control group matched for age, sex, BMI, and physical activity levels. RESULTS: In total, 18 AWD patients (mean age 12.6 ± 3.5 years) were included and there were no significant differences in anthopometric data compared to the control group (n = 18). AWD patients had a significantly lower GIQLI score (AWD mean 137.2 ± 6.8 vs. control mean 141.4 ± 4.9; p = 0.038) and were affected by decreased motor abilities with significantly higher Dordel-Koch-Test values (AWD median 3.54/IQR 1 vs. control median 2.8/IQR 1; p = 0.005). CONCLUSION: Follow-up examinations of AWD patients revealed decreased motor abilities and GIQLI scores while cardiopulmonary function was not different compared to healthy controls. The clinical impact of these findings remains to be elucidated. IMPACT: Clinical examination, assessment of the gastrointestinal quality of life, sport medical testing, electromyography and abdominal wall ultrasound were performed in patients with congenital abdominal wall defect and compared to an age and sex matched healthy control group. Results of spirometry and spiroergometry, ultrasound or electromyography did not significantly differ between the groups. Significantly decreased locomotor function and gastrointestinal quality of life were found in patients with abdominal wall defect. However, the clinical impact of these findings remains to be elucidated.

RESUMO

Hand fractures represent commonly encountered injuries in pediatric patients. However, due to modern means of mobility and product safety, the occurrence and distribution of these fractures have changed during the last decades. Therefore, it was the aim of this study to present an update of the epidemiology, pattern, and treatment of hand fractures in a large pediatric cohort. All patients aged between 0 and 17 years treated in our Department in 2019 with fractures of the phalanges, metacarpus, or carpus were included. The medical records were reviewed for age, gender, injury mechanism, fracture localization, season, and treatment. Patients were divided into three different age groups (0-5, 6-12, and 13-17 years). A total of 731 patients with 761 hand fractures were treated during the 1-year study period. The mean age was 11.1 ± 3.5 years, and the majority was male (65%). Male patients were significantly older compared to female patients (p = 0.008). Also, 78.7% of the fractures affected the phalanges, 17.6% the metacarpals, and 3.7% the carpal bones. The proximal phalanges were the most commonly fractured bones (41.5%). Patients with fractures of the carpus were significantly older compared to children sustaining fractures of the metacarpus or phalangeal bones (p < 0.001). Sixteen percent of our patients were treated surgically; these patients were significantly older compared to conservatively treated patients (p = 0.011).  Conclusion: The epidemiology, mechanisms of injury, distribution, and treatment of hand fractures significantly varies among different age groups. This knowledge is of importance for educational purposes of younger colleagues entrusted with care of children and adolescents as well as development of effective prevention strategies. What is Known: • Pediatric hand fractures represent the second most common fractures in children. • The epidemiology of pediatric hand fractures has changed during the last decades and therefore there is a need for an update regarding distribution and epidemiology of pediatric hand fractures. What is New: • In this retrospective cohort study, 761 pediatric hand fractures of 731 patients were analyzed in detail. • The main mechanisms of younger patients were entrapment injuries, older children most commonly sustained their fractures due to ball sport injuries. There was an increasing rate of metacarpal and carpal fractures with increasing age, and these fractures had to be treated operatively more often than phalangeal fractures.

RESUMO

This study focuses on the impact of a prevention program regarding dog bites in children. As a consequence of our previous investigation in 2005, we have initiated a child safety program for primary school children starting January 2008 until present to teach children how to avoid dog attacks and how to behave in case of an attack. In our retrospective study, we analyzed all patients younger than 15 years presenting with dog-related injuries between 2014 and 2018. As the main indicator for success of the prevention measures taken, we have defined the severity of injury in comparison to our previous study. Out of 296 children with dog-related injuries, 212 (71.6%) had sustained a dog bite. In the vast majority (n = 195; 92%), these patients presented with minor injuries; the extremities were most commonly affected (n = 100; 47%). Injuries to the head (n = 95; 45%) and trunk (n = 18; 8%) were less frequent. The proportion of severe injuries (8%) was significantly lower compared to our previous study, where 26% of children presented with severe injuries necessitating surgical intervention, while the number of patients requiring in-hospital treatment declined from 27.5% in the period 1994-2003 to 9.0% in the period between 2014 and 2018 (p < 0.05).Conclusion: Teaching of primary school children may effectively reduce the injury severity of dog bites. What is Known: • Dog bites are a substantial healthcare problem especially in children. What is New: • This study shows that a broad-based prevention program for primary school children can effectively decrease the severity but not the frequency of dog bite injuries in children.

RESUMO

There are conflicting recommendations regarding the amount of displacement necessitating stabilization of paediatric humeral medial epicondyle fractures. Our aim was to assess the reliability of the measurements of the displacement and the treatment recommendations of these fractures. The maximum displacement of 57 children with displaced humeral medial epicondyle fractures was analyzed on radiographs by six raters (4 paediatric surgeons, 2 paediatric radiologists) at two time points. In addition, the four surgeons recorded their treatment recommendation. Intraobserver and interobserver reliability were calculated with intraclass correlation coefficients (ICC) and Kappa values. The ICC for the intraobserver reliability ranged between 0.67 and 0.93. The raters disagreed with their own measurements between 8.8% and 28.1%. The ICC for the interobserver reliability of all six raters was 0.90 for measurement 1 and 0.93 for measurement 2. All six raters disagreed (difference > 2mm) in 93% of the cases in measurement 1 and in 91.2% in measurement 2. Treatment recommendations of the four paediatric surgeons between the two time points differed in 5.3% to 28.1% of the cases. Furthermore, the treatment recommendations were concordant in 24 cases (42%) at time point 1 and 32 cases (56.1%) at time point 2. In displaced paediatric medial epicondyle fractures, disagreement regarding measurement of displacement and recommendation for treatment is high. Validated and standardized measurement tools and a clear threshold for operative fixation of displaced medial epicondyle fractures are needed.

RESUMO

BACKGROUND: Patients following repair of an esophageal atresia (EA) or tracheoesophageal fistula (TEF) carry an increased risk of long-term cardiopulmonary malaise. The role of the airway microbiome in EA/TEF patients remains unclear. METHODS: All EA/TEF patients treated between 1980 and 2010 were invited to a prospective clinical examination, spirometry, and spiroergometry. The airway microbiome was determined from deep induced sputum by 16 S rRNA gene sequencing. The results were compared to a healthy age- and sex-matched control group. RESULTS: Nineteen EA/TEF patients with a mean age of 24.7 ± 7 years and 19 age- and sex-matched controls were included. EA/TEF patients showed a significantly lower muscle mass, lower maximum vital capacity (VCmax), and higher rates of restrictive ventilation disorders. Spiroergometry revealed a significantly lower relative performance capacity and lower peak VO2 in EA/TEF patients. Alpha- and beta-diversity of the airway microbiome did not differ significantly between the two groups. Linear discriminant effect size analysis revealed significantly enriched species of Prevotella_uncultured, Streptococcus_anginosus, Prevotella_7_Prevotella_enoeca, and Mogibacterium_timidum. CONCLUSION: EA/TEF patients frequently suffer from restrictive ventilation disorders and impaired cardiopulmonary function associated with minor alterations of the airway microbiome. Long-term examinations of EA/TEF patients seem to be necessary in order to detect impaired cardiopulmonary function. IMPACT: The key messages of the present study are a significantly decreased VCmax and exercise performance, as well as airway microbiome differences in EA/TEF patients. This study is the first to present parameters of lung function and exercise performance in combination with airway microbiome analysis with a mean follow-up of 24 years in EA/TEF patients. Prospective, long-term studies are needed to unravel possible interactions between alterations of the airway microbiome and impaired pulmonary function in EA/TEF patients.

RESUMO

PURPOSE: To compare performance data of adolescents collected with five different bicycle spiroergometry protocols and to assess the necessity for establishing standard values for each protocol. METHODS: One-hundred-twenty adolescents completed two bicycle spiroergometries within 14 days. One of the two tests was performed based on our institutional weight-adapted protocol (P0). The other test was performed based on one out of four exercise protocols widely used for children and adolescents (P1, 2, 3 or 4) with 30 persons each. The two tests were performed in a random order. Routine parameters of cardiopulmonary exercise tests (CPET) such as VO2peak, maximum power, O2 pulse, OUES, VE/VCO2 slope as well as ventilatory and lactate thresholds were investigated. Agreement between protocols was evaluated by Bland-Altman analysis, coefficients of variation (CV) and intra-class correlation coefficients (ICC). RESULTS: None of the CPET parameters were significantly different between P0 and P1, 2, 3 or 4. For most of the parameters, low biases between P0 and P1-P4 were found and 95% confidence intervalls were narrow. CV and ICC values largely corresponded to well-defined analytical goals (CV < 10% and ICC > 0.9). Only maximal power (Pmax) showed differences in size and drift of the bias depending on the length of the step duration of the protocols. CONCLUSION: Comparability between examination protocols has been shown for CPET parameters independent on step duration. Protocol-dependent standard values do not appear to be necessary. Only Pmax is dependent on the step duration, but in most cases, this has no significant influence on the fitness assessment.

RESUMO

We aimed to assess the in vitro antimicrobial activity and the in vivo effect on the murine fecal microbiome and volatile organic compound (VOC) profile of (S)-reutericyclin. The antimicrobial activity of (S)-reutericyclin was tested against Clostridium difficile, Listeria monocytogenes, Escherichia coli, Enterococcus faecium, Staphylococcus aureus, Staphylococcus (S.) epidermidis, Streptococcus agalactiae, Pseudomonas aeruginosa and Propionibacterium acnes. Reutericyclin or water were gavage fed to male BALBc mice for 7 weeks. Thereafter stool samples underwent 16S based microbiome analysis and VOC analysis by gas chromatography mass spectrometry (GC-MS). (S)-reutericyclin inhibited growth of S. epidermidis only. Oral (S)-reutericyclin treatment caused a trend towards reduced alpha diversity. Beta diversity was significantly influenced by reutericyclin. Linear discriminant analysis Effect Size (LEfSe) analysis showed an increase of Streptococcus and Muribaculum as well as a decrease of butyrate producing Ruminoclostridium, Roseburia and Eubacterium in the reutericyclin group. VOC analysis revealed significant increases of pentane and heptane and decreases of 2,3-butanedione and 2-heptanone in reutericyclin animals. The antimicrobial activity of (S)-reutericyclin differs from reports of (R)-reutericyclin with inhibitory effects on a multitude of Gram-positive bacteria reported in the literature. In vivo (S)-reutericyclin treatment led to a microbiome shift towards dysbiosis and distinct alterations of the fecal VOC profile.

RESUMO

The aim of this study was to analyze the exhaled volatile organic compounds (VOCs) profile, airway microbiome, lung function and exercise performance in congenital diaphragmatic hernia (CDH) patients compared to healthy age and sex-matched controls. A total of nine patients (median age 9 years, range 6-13 years) treated for CDH were included. Exhaled VOCs were measured by GC-MS. Airway microbiome was determined from deep induced sputum by 16S rRNA gene sequencing. Patients underwent conventional spirometry and exhausting bicycle spiroergometry. The exhaled VOC profile showed significantly higher levels of cyclohexane and significantly lower levels of acetone and 2-methylbutane in CDH patients. Microbiome analysis revealed no significant differences for alpha-diversity, beta-diversity and LefSe analysis. CDH patients had significantly lower relative abundances of Pasteurellales and Pasteurellaceae. CDH patients exhibited a significantly reduced Tiffeneau Index. Spiroergometry showed no significant differences. This is the first study to report the VOCs profile and airway microbiome in patients with CDH. Elevations of cyclohexane observed in the CDH group have also been reported in cases of lung cancer and pneumonia. CDH patients had no signs of impaired physical performance capacity, fueling controversial reports in the literature.

RESUMO

BACKGROUND: Following transplantation of human neuroblastoma (NB) cells into athymic mice, we investigated the effects of tumor growth and cyclophosphamide (CTX) treatment on systemic metabolism, gut inflammation and permeability, fecal microbiome and volatile organic compounds (VOCs). METHODS: NB cells (MHH-NB11) were implanted into athymic mice (n=20); 20 healthy mice served as controls (sham).  CTX was given to 20 animals (10 NB and 10 sham) after 8 and 9 weeks. Metabolic changes were measured. Ileum samples were obtained for RT-PCR (claudins 2 and 4, occludin, tight junction protein 1) and apoptosis rate determination. Fecal microbiome and VOCs were analyzed. Values were compared to sham animals. RESULTS: NB caused reduction of adipose tissue, increases of IL-6 and TNF-α, and decreases of TGF-ß1 and -ß2. Serum FITC-dextrane levels were increased in NB and improved under CTX. Claudin 4 expression was higher in NB versus NB + CTX and sham animals. NB caused increased apoptosis of epithelial cells. NB but also CTX led to a reduction in the abundance of Lactobacillus. NB led to alterations of the fecal VOC profile. CONCLUSIONS: NB caused a catabolic pro-inflammatory state, increased gut permeability, altered fecal VOCs and reductions of Lactobacillus. Further investigations are required to determine if modifications of the intestinal microbiome may reverse some of the observed effects.

RESUMO

The aim of this study was to evaluate whether spiroergometry performance in adolescent alpine ski racers can predict later advancement to a professional career. Over 10 consecutive years, adolescent skiers of the regional Austrian Youth Skier Squad (local level) underwent annual medical examinations, including exhaustive bicycle spiroergometry. The performance was determined at fixed (2 and 4 mmol/l serum lactate) and individual (individual anaerobic threshold (IAT) and lactate equivalent (LAE)) thresholds. Data from the last available test were compared between skiers who later advanced to the professional level (Austrian national ski team) and those who did not. Ninety-seven alpine skiers (n=51 male; n=46 female); mean age 16.6 years (range 15-18) were included. Of these, 18 adolescents (n=10 male; n=8 female) entered a professional career. No significant differences were found for maximum oxygen uptake (VO2max). Athletes advancing to the professional level had significantly higher performance and VO2 at LAE. Additionally, male professionals had significantly higher performances at fixed thresholds and the IAT. The performance and VO2 at the LAE, and thus the ability to produce power at a particular metabolic threshold, was the most relevant spiroergometric parameter to predict a later professional career.

RESUMO

PURPOSE: The aim of the present study was to describe epidemiology, management and outcome of pediatric and adolescent patients with posterior cruciate ligament (PCL) injuries. METHODS: Sixteen patients of less than 18 years of age with 7 PCL avulsion fractures and 9 PCL tears were included over a 10-year period. Trauma mechanism, additional injuries and treatment methods were analyzed. Follow-up examination included range of motion and ability to perform squats. Pedi-IKDC and Lysholm score were obtained and posterior shift was measured in kneeling view radiographs and compared to the contralateral side. Patients were grouped into pediatric patients with open physes at the time surgery and adolescent patients with closing or closed physes. In case of open physes, growth disturbances were assessed. RESULTS: Six of the treated patients (median age 12.5 years, range 10-13) had open physes at time of surgery. Five of those sustained avulsion fractures and treatment consisted of open reduction and screw fixation in four cases and graft reconstruction in one case. One patient sustained a PCL tear and underwent graft reconstruction. Follow-up at a median of 71.5 months (range 62-100) did not reveal any growth disturbances. Median Pedi-IKDC was 71.9 (range 51.7-92.1), median Lysholm score was 81.5 (range 66-88) and median posterior shift difference was 2.5 mm (range 0-11). The remaining 10 patients (median age 16 years, range 14-17) had closing/closed physis at the time of operation. Two patients presented with avulsion fractures treated with open reduction and screw fixation and 8 patients sustained PCL tears treated with graft reconstruction. At a median follow-up of 69.5 months (range 11-112), median Pedi-IKDC was 86.8 (range 36.8-97.7), median Lysholm score was 84.0 (range 45-95) and median posterior shift difference was 4 mm (range 0-15). CONCLUSIONS: In our small number of pediatric patients with PCL injuries, open reduction and epiphyseal screw fixation of displaced avulsed fractures and steep tunnel drilling in case of PCL reconstruction did not cause growth disturbances. Nevertheless, long-term functional impairment should be expected and close follow-up has to be recommended. LEVEL OF EVIDENCE: Therapeutic, Level IV.

RESUMO

BACKGROUND: The aim of this study was to determine the diagnostic capacity of hepcidin in pediatric acute appendicitis and its accuracy as a predictor of the severity of appendicitis. MATERIALS AND METHODS: In children with appendicitis (n = 39), leukocytes, platelet count, and the serum levels of C-reactive protein (CRP) and hepcidin were compared to a control group (n = 25) of patients with unspecific abdominal pain. Additionally, parameters were compared between children with simple (n = 17) and complicated appendicitis (n = 22). Receiver operation characteristic analyses of the different parameters were performed and the areas under the curve (AUCs) calculated. RESULTS: Leukocytes and serum hepcidin levels were significantly higher in children with acute appendicitis versus control group (13.7 ± 5.7 versus 9.8 ± 3.9 G/L, P = 0.005 and 31.3 ± 21.7 versus 20.4 ± 14 ng/mL, P = 0.039). AUCs for hepcidin, leukocytes, and CRP were 0.654, 0.711, and 0.619, respectively. Complicated appendicitis was associated with significantly higher hepcidin concentrations compared to simple appendicitis (38.5 ± 17.6 ng/mL versus 21.6 ± 23.4 ng/mL, P < 0.001). A combination of leukocytes, CRP, and hepcidin had the highest AUC (0.914) to predict complicated appendicitis. CONCLUSIONS: Increased serum levels of hepcidin were found in children with appendicitis compared to controls. While hepcidin was useful to identify patients with complicated appendicitis as it does not seem appropriate to distinguish between simple appendicitis and other causes for acute abdominal pain.

RESUMO

OBJECTIVE: To assess the effect of neuroblastoma (NB) on the intestinal microbiome, metabolism, and inflammatory parameters in a murine model. MATERIALS AND METHODS: Athymic Hsd:Fox1nu mice received subperitoneal implantation of human NB cells (MHH-NB11) (tumor group, TG) or culture medium (sham group). Following 10 weeks of tumor growth, all animals were sacrificed to collect total white adipose tissue (WAT). Luminex assays were performed for gut hormone and inflammation marker analysis. Bile acids were measured by high-performance liquid chromatography-mass spectrometry in feces and serum. The microbiome of the ileal content was determined by 16S rDNA next-generation sequencing. RESULTS: At 10 weeks, tumors masses in the TG reached a mean weight of 1.10 g (interquartile range 3.45 g) associated with a significant reduction in WAT. Furthermore, in the TG, there was a marked reduction in leptin and an increase in glucagon-like peptide 1 serum levels. Moreover, the TG mice displayed a pro-inflammatory profile, with significant increases in monocyte chemotactic protein 1, tumor necrosis factor alpha, and interleukin-10. Lithocholic acid, deoxycholic acid, and ursodeoxycholic acid were significantly decreased in the stool of TG mice. Significant alterations of the intestinal microbiome were found in the ileal contents of the TG. CONCLUSIONS: The present study provides a first glimpse that human NB in a murine model induces tumor cachexia associated with alterations in metabolic and inflammatory parameters, as well as changes in the intestinal microbiota. Since the intestinal microbiome is known to contribute to the host's ability to harvest energy, a favorable modulation of the intestinal microbiome in tumor patients could potentially represent a novel therapeutic target to prevent tumor-associated cachexia.

RESUMO

PURPOSE: Different treatment methods including immediate mobilization with or without brace, bed rest or immobilization using thoracolumbosacral orthosis have been applied for stable compression fractures of the pediatric spine. The aim of this study was to evaluate the influence of bracing on the remodeling capacity of pediatric thoracolumbar type A 1.2 impaction fractures. Additionally, the prevalence of pain and functional disabilities were assessed. METHODS: All children treated conservatively between 2000 and 2011 with impaction fractures of the thoracolumbar spine (A 1.2) were included and re-invited for a clinical [including VAS 0-100, Oswestry disability index (ODI)] and radiological follow-up examination. Changes of the sagittal index (SI) at the time of the accident, the latest control visit and at the follow-up examination were analyzed. RESULTS: Seventy-two patients with a mean age of 12 years (1.8-18 years) and a total number of 133 fractured vertebrae were included. The mean SI at the time of injury was 0.76 (range 0.45-0.94, SD 0.08); 34 patients with 67 fractured vertebrae were included in the follow-up examination after a mean of 7.9 years (2.4-13.1 years). The mean SI of the 67 affected vertebrae at follow-up significantly increased to 0.92 (range 0.74-1, SD 0.06). The initial treatment regimen (brace vs no brace) did not influence the remodeling capacity. More than half of the patients (n = 18, 53 %) complained about occasional back-related pain which was not associated with the remodeling process. The mean ODI was 5.8 (range 0-26, SD 6.6) and the mean VAS of the re-evaluated patients was 87 (range 53-100, SD 14). CONCLUSIONS: A significant remodeling capacity of thoracolumbar vertebral impaction fractures sustained in childhood is demonstrated. Bracing does not seem to influence the long-term outcome of these injuries. More studies have to be performed to define the role of bracing in these fractures.

Background and purpose - Heavily displaced radial neck fractures in children are sometimes associated with poor outcome. A substantial number of these fractures require open reduction. We hypothesized that Judet type-IV fractures with a completely displaced radial head would result in a worse outcome than radial neck fractures with remaining bony contact. Patients and methods - We analyzed 19 children (median age 9.7 (4-13) years) who were treated for Judet type-IV radial neck fractures between 2001 and 2014. The outcome was assessed at the latest outpatient visit using the Linscheid-Wheeler score at a median time of 3.5 (1-8) years after injury. The patients were assigned either to group A (9 fractures with remaining bony contact between the radial head and the radial neck) or to group B (10 fractures without any bony contact). Results - The 2 groups were similar concerning age and sex. The rate of additional injuries was higher in group B (7/10 vs. 1/9 in group A; p = 0.009). The rate of open reduction was higher in group B (5/10 vs. 0/9 in group A; p = 0.01). Poor outcome was more common in group B (4/10 vs. 0/9 in group A; p = 0.03). In group B, the proportion of children with poor outcome (almost half) was the same irrespective of whether open or closed reduction had been done. Interpretation - The main causes of unfavorable results of radial neck fracture in children appear to be related to the energy of the injury and the amount of displacement-and not to whether open reduction was used.

RESUMO

PURPOSE: The aim of this study was to determine the incidence of gastroschisis-related complications (GRCs) after closure of the abdominal wall defect, with a focus on frequency, type and timing of required surgical interventions, and to identify the impact of these on further outcome. METHODS: All gastroschisis patients treated from 1975 to 2008 in a tertiary-level center were retrospectively reviewed. Surgical procedures for GRCs following abdominal wall closure of simple gastroschisis [SG (intact continuous bowel)] and complex gastroschisis [CG (additional gastrointestinal malformations)] were compared, and outcomes were determined. RESULTS: One hundred and eight patients were identified with a median follow-up of 15.0 years (range 4-37). Ninety-four (87%) had SG, and 14 (13%) CG. Surgical interventions for GRCs were performed in 28 (26%) patients with 16 requiring multiple operations. Overall, 60 surgical procedures were performed. Bowel obstruction (n = 34) was the most common GRC, followed by anastomotic stricture (n = 8) and ischemic bowel (n = 3). The median interval between gastroschisis closure and secondary surgery for GRCs was 62.5 days (range 1 day-15 years). Surgical interventions were significantly more frequent in CG compared with SG [12/14 (86%) vs. 16/94 (17%); P < 0.0001]. The overall survival rate was 90%. Significantly, more patients required parenteral nutrition for more than 28 days [9/28 (32%) vs. 13/80 (16 %); P = 0.0468], longer median time to achieve full enteral feedings (87 vs. 33 days; P < 0.0001) and longer median hospital stay (117 vs. 54 days; P < 0.0001) compared with those not requiring additional surgery. CONCLUSION: GRCs requiring surgical interventions were more common in patients with CG, which were associated with delay in achieving full enteral feedings and prolonged hospital stay.

RESUMO

PURPOSE: To evaluate the influence of proton pump inhibitors (PPI) in predominantly milk-fed infants with symptoms of GERD by 24-h pH-multichannel intraluminal impedance (24-h pH-MII). METHODS: Ten infants (8 males and 2 females) with a mean gestational age of 39 weeks (28-40) were included. 24-h pH-MII was performed before prescription and during intake of PPI. Total acid exposure time, bolus exposure time (acidic/non-acidic/total) and the number of refluxes (acidic/non-acidic/total) were determined. Clinical symptoms were recorded and used to calculate the Reflux Symptom Index (RSI) and the Symptom Severity Index (SSI). RESULTS: There was a significant decrease in the number of acidic refluxes, total acid exposure and acidic bolus exposure time. However, this went along with a significant increase in non-acidic bolus exposure time. The total number of refluxes and the total bolus exposure time remained unchanged. Under PPI, a decrease of SSI and RSI for pain-related symptoms could be observed. For respiratory symptoms and vomiting however no significant changes could be demonstrated. CONCLUSIONS: Under PPI, an improvement of pain-related symptoms could be shown. The decrease of acid exposure went along with an increase of non-acidic refluxes resulting in almost constant total reflux numbers. This finding is interpreted as main reason for some persisting symptoms despite adequate PPI dosage. Concluding from our data PPI therapy should only be indicated in case of pain, but has no effect in case of vomiting or recurrent respiratory symptoms.

RESUMO

Intrauterine ovarian torsion is a rare event, but it is a possible cause for unilateral ovarian aplasia. Most commonly the ovary undergoes autolysis after torsion so that no tissue or remnants can be discovered on the involved side. We report a rare case of unilateral intrauterine torsion followed by autoamputation and abdominal reimplantation resulting in an intra-abdominal complex cystic mass with a review of the literature.

RESUMO

(1) Background: Displaced supracondylar humeral fractures in pediatric patients can be treated by either antegrade nailing (AN) or percutaneous crossed pinning (PCP). The aim of this study was to compare the intra- and perioperative management, complications and outcome of AN and PCP. (2) Methods: This retrospective study enrolled 271 individuals (median age 5 years, IQR 4-7 years) who underwent AN (n = 173) or PCP (n = 98). Patient history was analyzed for incidence of nerve injuries, postoperative treatment, postoperative malrotation, time of hospital stay, time to implant removal and revision rate. Operative procedures were investigated for duration and radiation exposure. (3) Results: PCP was associated with a significantly lower radiation exposure (dose area product: PCP mean 20.1 cGycm2 vs. AN mean 34.7 cGycm2, p < 0.001; fluoroscopy time: PCP mean 1.1 min, range 0.1-8.1 min, vs. AN mean 1.5 min, range 0.1-7.1 min, p < 0.001), duration of surgery (PCP mean 32.2 min vs. AN mean 48.3 min, p < 0.001) and time to implant removal (PCP mean 37 days vs. AN mean 113 days, p < 0.001). Cast removal was performed earlier in the AN group (PCP mean 30.2 days vs. AN mean 20.4 days, p < 0.001) and there were fewer iatrogenic nerve lesions (PCP: 24% vs. AN: 8%, p < 0.001). (4) Conclusions: In the investigated study population, the analyzed parameters seem to favor the use of PCP. The advantages of AN should be weighed against its drawbacks. For special indications, AN remains a relevant technique in supracondylar fracture treatment, and surgeons should be familiar with this procedure.

RESUMO

Cancer therapy is often associated with severe side effects such as drug induced weight loss, also known as chemotherapy-induced cachexia. The aim of this study was to investigate the effects of a multispecies probiotic (OMNi-BiOTiC® 10 AAD) in a chemotherapy mouse model. A total of 24 male BALB/c mice were gavage-fed with the probiotic formulation or water, once a day for 3 weeks. In the third week, the mice received intraperitoneal cyclophosphamide. At euthanasia, the organs were dissected, and serum was sampled for cytokine analysis. Tight junction components, myosin light chain kinase, mucins, and apoptosis markers were detected in the ileum and colon using histological analyses and qRT-PCR. Lipolysis was analyzed by enzymatic activity assay, Western blotting analyses, and qRT-PCR in WAT. The fecal microbiome was measured with 16S-rRNA gene sequencing from stool samples, and fecal volatile organic compounds analysis was performed using gas chromatography/mass spectrometry. The probiotic-fed mice exhibited significantly less body weight loss and adipose tissue wasting associated with a reduced CGI58 mediated lipolysis. They showed significantly fewer pro-inflammatory cytokines and lower gut permeability compared to animals fed without the probiotic. The colons of the probiotic-fed animals showed lower inflammation scores and less goblet cell loss. qRT-PCR revealed no differences in regards to tight junction components, mucins, or apoptosis markers. No differences in microbiome alpha diversity, but differences in beta diversity, were observed between the treatment groups. Taxonomic analysis showed that the probiotic group had a lower relative abundance of Odoribacter and Ruminococcus-UCG014 and a higher abundance of Desulfovibrio. VOC analysis yielded no significant differences. The results of this study indicate that oral administration of the multispecies probiotic OMNi-BiOTiC® 10 AAD could mitigate cyclophosphamide-induced chemotherapy side effects.
