Abstract
Aviation is a tremendously complex process involving multiple factors that can be subsidiary to human error. The implementation of checklists, tools that reduce this risk, has often been extrapolated to other fields, especially medicine. Through this reflection, we comment on the critical and relevant aspects of pediatric surgical patient safety, briefly discussing the existing literature and analyzing potential areas for improvement.

Abstract
Background: Pediatric acute appendicitis (PAA) involves a substantial consumption of health and economic resources. The identification of serum biomarkers that may help predict the post-surgical evolution of these patients is a field of great interest. Patients and Methods: This was a prospective, observational substudy within the Biomarkers for the Diagnosis of Appendicitis in Pediatrics (BIDIAP) cohort aimed at evaluating the association between post-surgical increase in serum IL-6 and different outcomes related to the clinical evolution of children operated on for PAA. Sixty-nine children with a confirmed diagnosis of acute appendicitis and both pre-operative and post-operative serum IL-6 were included in the study. Three multivariable-adjusted linear regression models were fitted to analyze the association between an increase of >10% in post-operative serum IL-6 level with the length of stay, the number of post-operative emetic episodes, and the onset of oral feeding. Two multivariable-adjusted logistic regression models were fitted to assess the association of the same exposure with the indication of antibiotherapy at discharge and with positivity in peritoneal fluid culture. Results: Thirteen children showed an increase of >10% in the post-operative serum IL-6 value (group 1) whereas 56 showed only a minor increase, or no change (group 2). After accounting for potential confounders, children in group 1 had a mean of three-day longer hospital stay (difference, 3.33; 95% confidence interval [CI], 0.57-6.09) and higher odds of a positive result in peritoneal fluid culture (odds ratio [OR], 37.43; 95% CI, 1.02-1361.28) than children in group 2. Conclusions: An increase of >10% in post-operative serum IL-6 value could predict longer hospital stay and higher odds of positive peritoneal fluid culture. Future prospective studies are needed to replicate these findings and to broaden the range of biomarkers that could predict the post-operative evolution of children operated on for PAA.

Development and clinical application of a new sternal zenithal traction system in video-assisted percutaneous thoracoplasty. Cir Esp 2023; 101:319-324. [PMID: 36067947 DOI: 10.1016/j.cireng.2022.09.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Accepted: 01/26/2022] [Indexed: 05/16/2023]
Abstract
INTRODUCTION Video-assisted percutaneous thoracoplasty involves a complex surgical access with risk of damaging vital structures during the procedure. Historically, different traction and sternal elevation systems have been applied during the intervention to minimize the risk associated with the passage of the instruments between the sternum and the pericardium. MATERIAL AND METHODS A new sternal traction system is presented by means of an illustrated description. Clinical and sociodemographic data were extracted from the 36 patients operated in our center for Pectus Excavatum between July 2017 and August 2021. The Haller index was not applied as a criterion to determine the use or not of the sternal traction system. Patients were classified according to whether the sternal traction system (TE) or not (ST) had been employed. Statistical analysis of the data collected was performed with STATA, version 15.0 (StataCorp). RESULTS Both groups were comparable. Haller's Index was 4.19 ± 0.7 for the sternal traction (TE) group and 3.79 ± 0.3 for the no sternal traction (ST) group. In 25 of the patients the described traction system was used, and in 11 no traction system was used. All patients were operated on by the same surgeon. The mean operative time in minutes was 97.73 ± 46.2 for the ST group and 88.13 ± 18.1 for the TE group (p = 0.87). The mean total days of admission was 7.67 ± 0.82 (TE) and 7.73 ± 1.35 (ST). Mean days of intravenous PCA was 6.08 ± 0.72 (TE) and 5.89 ± 1.45 (ST). The mean number of epidural PCA days was 3.79 ± 0.5 (TE) and 3.36 ± 0.5 (ST) (p = 0.01). All patients presented a favorable postoperative evolution. None of the patients presented discomfort at the level of the sternal wounds during hospitalization. Cosmetic evolution was favorable in all patients. CONCLUSIONS The sternal traction system presented provides safety when performing retrosternal dissection and placement of the thoracoplasty bar, leading to a decrease in surgical time in cases with a Haller Index higher than 3.5. There have been no complications associated with its use, nor has there been an increase in the number of days of hospitalization or analgesic requirements. There are no aesthetic sequelae for the patients.

Abstract
BACKGROUND Pediatric acute appendicitis (PAA) continues to be a diagnostic challenge today. The diagnostic performance of classical indices is only moderate, especially in pediatric population. This study aimed to define a clinical, radiological and analytical index for the diagnosis of PAA. MATERIALS AND METHODS This prospective study included 151 patients divided into two groups: (1) 53 patients with non-surgical abdominal pain (NSAP) and (2) 98 patients with a confirmed PAA. Sociodemographic and clinical characteristics were compared between groups using the Mann-Whitney U test and the Fisher exact test. To identify the predictors of PAA, we performed a multivariable logistic regression using a forward stepwise analysis and we assigned multiples of integer values to the selected variables. The diagnostic performance of the index was assessed by calculating the area under the receiver operating characteristic curve. Intra-cohort calibration was assessed with the Hosmer-Lemeshow test. RESULTS We developed the BIDIAP index (BIomarkers for the DIagnosis of Appendicitis in Pediatrics), which included three variables that independently predicted higher odds of PAA: appendiceal caliber (≥ 6.9 mm), systemic immune-inflammation index (≥ 890) and peritoneal irritation, which scored 4, 3 and 2 points, respectively. Mean (SD) score of the participants was 2.38 (2.06) in group 1 and 7.89 (1.50) in group 2. The area under the ROC was 0.97 (95% CI 0.95-0.99). The cut-off point was established at 4 points, resulting in a sensitivity of 98.98% and a specificity of 77.78%. CONCLUSIONS The BIDIAP index has an exceptional diagnostic performance in PAA. The importance of these results lies in its novelty and in the simplicity of the index. Although external validation will be necessary, initial results look promising.

Abstract
Background: Neuroglial heterotopia, characterized by mature -neuroglial tissue outside the central nervous system, has not been previously associated with cranioschisis. Case Report: A 4-year-old female patient, with left congenital anophthalmia, had a nasofrontal neuroglial heterotopia protruding through an ossification defect. Discussion: Nasofrontal cranioschisis may be associated with neuroglial heterotopias. The combination of anophthalmia and neuroglial heterotopia, previously described only once in the literature, may be part of a broader malformation spectrum that has not been properly characterized to date.

Abstract
Background: The literature regarding alterations in the coagulation profile in pediatric acute appendicitis (PAA) is scarce and mainly limited to retrospective studies. Evidence on the diagnostic yield of coagulation parameters is limited to fibrinogen. Patients and Methods: This is a prospective study with 151 patients divided into two groups: patients with nonsurgical abdominal pain (NSAP) in whom the diagnosis of PAA was excluded (n = 53) and patients with a confirmed diagnosis of PAA (n = 98). In 93 patients (62%), a coagulation study was obtained at the time of diagnosis and international normalized ratio (INR), activated partial thromboplastin time (aPTT), d-dimer, platelets, mean platelet volume, and platelet-to-lymphocyte ratio were analyzed. The PAA group was further classified into complicated (n = 19) and non-complicated PAA (n = 40). Quantitative variables were compared between groups using the Mann-Whitney U test. Diagnostic performance of the coagulation profile was evaluated with the area under the receiver operating characteristic (ROC) curves. Results: Patients with NSAP had lower median levels of INR, fibrinogen and d-dimer than those with PAA. Moreover, patients with complicated PAA had higher median values of INR and fibrinogen. None of the patients needed specific treatment for the correction of coagulopathy. Fibrinogen was the parameter with the highest diagnostic yield for distinguishing between NSAP and PAA (area under the curve [AUC], 0.74; 95% confidence interval [CI], 0.65-0.85), as well as between complicated versus non-complicated PAA (AUC, 0.71; 95% CI, 0.57-0.86). Conclusions: This study found a moderate extrinsic pathway coagulopathy in patients with PAA, especially in complicated PAA. Fibrinogen is a parameter with moderate diagnostic yield for the diagnosis of PAA.

Abstract
The perineal presentation of plexiform neurofibroma is exceptional, with only two cases reported to date. We present an 8-year-old African male with a large perineal tumor of years of evolution. He had no associated symptoms. Café au lait stains were observed on examination, without other findings of relevance. The patient had no preoperative radiological studies. Partial excision of the lesion was performed. Histopathological study of the specimen revealed a plexiform neurofibroma. The lack of diagnostic suspicion due to the atypical nature of the location, the anatomical complexity of surgical resection and the potential urological and rectal involvement make this lesion a diagnostic-therapeutic challenge. Among the differential diagnoses, schwannoma, congenital lipoma, hamartoma and lipoblastoma should be considered.

Abstract
INTRODUCTION The diagnostic performance of capillary ketonemia (CK) has been previously evaluated in context of pediatric acute gastroenteritis. To our knowledge, there is no literature on its performance in the setting of pediatric acute appendicitis (PAA). MATERIALS AND METHODS In this study, 151 patients were prospectively included and divided into two groups: (1) patients with non-surgical abdominal pain in whom the diagnosis of PAA was excluded (n = 53) and (2) patients with a confirmed diagnosis of PAA (n = 98). In 80 patients (Group 1, n = 23 and group 2, n = 57) a CK was measured at the time of diagnosis. The PAA group was further classified into complicated (n = 18) and uncomplicated PAA (n = 39). Quantitative variables were compared between groups using the Mann-Whitney U test. Diagnostic performance of CK was evaluated with ROC curves. RESULTS CK values were 0.3 [0.1-0.9] mmol/L in group 1 and 0.7 [0.4-1.4] mmol/L in group 2 (p = 0.01). Regarding the type of PAA, CK values were 0.6 [0.4-0.9] mmol/L in uncomplicated PAA and 1.2 [0.8-1.4] mmol/L in complicated PAA (p = 0.02). The AUC for the discrimination between groups 1 and 2 was 0.68 (95% IC 0.53-0.82) (p = 0.24) and the AUC for the discrimination between uncomplicated PAA and complicated PAA was 0.69 (95% IC 0.54-0.85) (p = 0.04). The best cut-off point (group 1 vs group 2) resulted in 0.4 mmol/L, with a sensitivity of 80.7% and a specificity of 52.2%. The best cut-off point (non-complicated vs complicated PAA) resulted in 1.1 mmol/L, with a sensitivity of 61.1% and a specificity of 76.9%. CONCLUSIONS This study found significantly higher levels of CK in patients with PAA than in those with NSAP. Similarly, significantly higher levels were observed in patients with complicated than in those with uncomplicated PAA. Nevertheless, the diagnostic performance of CK was only moderate in the two settings analyzed. The potential usefulness of CK determination as a tool to guide the preoperative rehydration regimen of patients with PAA to prevent postoperative hyporexia and vomiting is a promising line of research and should be evaluated in future studies.

Abstract
Glans ischemia is an extremely infrequent complication characterized by a total or partial compromise in the penile arterial perfusion. A 15-year-old male patient suffered an episode of ischemia in the glans penis post-circumcision 24 h after surgery. Intravenous treatment with continuous perfusion of pentoxifylline was started for 4 days, with favorable evolution. Complete resolution was observed with no sequelae. There is no consensus on the best therapeutic management. The favorable evolution reported in most of the cases despite different therapeutic approaches leads us to think that the role of the treatments proposed so far is probably less than we believe. Additionally, we present a proposal for a diagnostic and therapeutic guide for this entity. Although the evidence in the literature is scarce and this guideline should be interpreted with caution, we believe that it can constitute a support resource for cases similar to ours.

Abstract
INTRODUCTION Pediatric acute appendicitis (PAA) is a pathology with a high rate of diagnostic error. The search for new diagnostic tools is justified by the high morbidity and healthcare costs associated with diagnostic error. METHODS We designed a prospective study to validate serum pentraxin-3 (PTX3) as a diagnostic tool in PAA. Participants were divided into three groups: (1) patients with no underlying pathology (2) patients with non-surgical abdominal pain and (3) patients with a confirmed diagnosis of PAA. For further analyses, patients in group 3 were divided into complicated or uncomplicated PAA. Quantitative variables were expressed as medians and interquartile ranges and categorical variables as percentages. Quantitative variables were compared using the Kruskal-Wallis test and the Mann-Whitney U test. Diagnostic performance was evaluated with ROC curves. RESULTS This study included 215 patients divided into group 1 (n = 63), group 2 (n = 53) and group 3 (n = 99). Median serum PTX3 values were 2.54 (1.70-2.95) ng/mL, 3.29 (2.19-7.64) ng/mL and 8.94 (6.16-14.05) in groups 1, 2 and 3, respectively (p = 0.001). Patients with complicated PAA showed significantly higher values than patients with uncomplicated PAA (p = 0.04). The AUC (group 2 vs. 3) was 0.77 (95% CI 0.69-0.85) and the best cut-off point was at 7.28 ng/mL, with a sensitivity of 61.3% and a specificity of 73.1%. The AUC (complicated vs. uncomplicated PAA) was 0.65 (95% CI 0.54-0.77) and the best cut-off point was 12.33 ng/mL, with a sensitivity of 51.72% and a specificity of 72.73%. CONCLUSIONS The diagnostic ability of serum PTX3 in PAA is only moderate and therefore it cannot be considered a definitive diagnostic test. The discriminatory ability of PTX3 between complicated and uncomplicated PAA is poor. These findings, which contrast with those reported to date, should be validated with future properly designed prospective studies.

Abstract
Congenital prepubic sinus (PS) is an extremely infrequent malformation consisting of a prepubic fistulous tract that classically does not communicate with the genitourinary system. Previous studies centered on its immunohistochemical characterization have shown inconsistent results, and the etiology has not been clarified. We present the case of a 2-year-old male who presented since birth with a fistulous orifice on the dorsum of the penis. He had no associated symptoms. Under general anesthesia, the fistulous tract was explored, and methylene blue was instilled through it. After cystoscopically verifying the absence of communication with the urethra, a complete resection of the lesion was performed. The immunohistochemical study showed positivity for low and high molecular weight keratins and a transitional pattern for keratin 7 and GATA3, with positivity at cul de sac level and negativity at proximal level. These findings suggest that this lesion is an incomplete dorsal duplication variant.

Abstract
BACKGROUND Pediatric acute appendicitis (AA) is a challenging pathology to diagnose. In the last decades, multiple biomarkers have been evaluated in different human biological samples to improve diagnostic performance. This study aimed to examine the diagnostic performance of serum, fecal and urinary calprotectin as well as the role of the APPY-1 biomarker panel in pediatric acute appendicitis. METHODS We conducted a systematic review of the literature that involved an extensive search in the main databases of medical bibliography (Medline, PubMed, Web of Science and SciELO). Two independent reviewers selected the relevant articles based on the previously defined inclusion and exclusion criteria. Methodological quality of the selected article was rated using the QUADAS2 index. Data extraction was performed by two independent reviewers. A synthesis of the results, a standardization of the metrics and two random-effect meta-analyses, one for serum calprotectin and one for APPY-1, were performed. RESULTS The research resulted in 173 articles. Thirty-eight duplicates were removed. Among the remaining 135 articles, we excluded 125 following the inclusion and exclusion criteria, resulting in the 10 studies included in this review. This systematic review included data from of 3901 participants (1276 patients with confirmed diagnosis of AA and 2625 controls). The age of the participants ranged from 0 to 21 years. Four of the studies compared serum calprotectin values and reported significant differences between groups, but inconsistent results regarding cutoff points, sensitivity and specificity. Two publications compared urinary values of calprotectin and presented inconsistent results regarding sensitivity and specificity as well. One publication evaluated the diagnostic performance of fecal calprotectin, but it did not provide data on measured values. Four studies evaluated the diagnostic performance of APPY-1 test in pediatric acute appendicitis. The calculated pooled sensitivity and specificity of those studies were 97.37 (95% CI 95.60-98.44) and 36.74 (95% CI 32.28-41.44), respectively, and the calculated pooled NLR, 0.0714 (95% CI 0.041-0.115). CONCLUSION Serum calprotectin has limited diagnostic yield in pediatric acute appendicitis. Its performance seems to increase with the hours of clinical evolution and in advanced AA, although the evidence is limited. There is not enough evidence on the usefulness of urinary or fecal calprotectin in the diagnosis of pediatric acute appendicitis. On the other hand, the APPY-1 is a reliable test to exclude the diagnosis of AA in patients at low or moderate risk according to PAS and Alvarado Score.

Abstract
BACKGROUND Despite the radiological and analytical advances of the last decades, there is still a significant rate of diagnostic error in pediatric acute appendicitis. In recent years, multiple biomarkers have emerged as potential diagnostic tools. This study aimed to examine the diagnostic performance of serum interleukin-6 in pediatric acute appendicitis. METHODS We conducted a systematic review of the literature that involved an extensive search in the main databases of medical bibliography (Medline, PubMed, Web of Science and SciELO). Two independent reviewers selected the relevant articles based on the previously defined inclusion and exclusion criteria. Methodological quality of the selected article was rated using the QUADAS2 index. Data extraction was performed by two independent reviewers. RESULTS The research in the medical bibliography databases resulted in 68 articles. We removed 26 duplicates. Among the remaining 42 articles, we excluded 33 following the inclusion and exclusion criteria. Of the final 9 studies included in this review, 8 provided measured serum interleukin-6 values, and all of them reported significant differences between groups, but inconsistent results regarding sensitivity and specificity. CONCLUSIONS The diagnostic performance of interleukine-6 alone for the diagnosis of acute appendicitis in children is limited. The sensitivity and specificity of interleukine-6 for the diagnosis of non-complicated acute appendicitis in the pediatric population are moderate but increased in complicated appendicitis. There seems to be a direct relationship between serum level of interleukin-6 and the hours of evolution of abdominal pain in children with acute appendicitis. The increasingly widespread use of non-operative management of acute appendicitis warrants further exploration of the classificatory potential of this marker between complicated and uncomplicated appendicitis. We consider that this may be an avenue of research to explore in the future.

Abstract
BACKGROUND Serum interleukin-6 (IL-6) has a moderate diagnostic performance in pediatric acute appendicitis (PAA). The evidence regarding its capacity to discern between complicated and uncomplicated PAA is scarce. METHODS We designed a prospective observational study to validate serum IL-6 as a marker for diagnostic classification between complicated and uncomplicated PAA. This study included 205 patients divided into three groups: (1) patients who underwent major outpatient surgery (n = 57); (2) patients with non-surgical abdominal pain (NSAP) in whom the diagnosis of PAA was excluded (n = 53), and (3) patients with a confirmed diagnosis of PAA (n = 95). The PAA patients were further classified as uncomplicated or complicated PAA. IL-6 concentration was determined in all patients at diagnosis. Comparative statistical analysis was performed using the Mann-Whitney U test, the Fisher exact test and the Kruskall Wallis test. The area under the receiver operating characteristic curves (AUC) were calculated. RESULTS Median (interquartile range, IQR) serum IL-6 values were 2 pg/mL (2.0-3.4) in group 1, 3.9 pg/mL (2.4-11.9) in group 2, and 23.9 pg/mL (11.1-61.0) in group 3 (P < 0.001). Among the participants in group 3, those with uncomplicated PAA had median (IQR) serum IL-6 values of 17.2 pg/mL (8.5-36.8), and those with complicated PAA had 60.25 pg/mL (27.1-169) serum IL-6 (P < 0.001). At the cut-off point of 19.55 pg/mL, the AUC for the discrimination between patients in group 2 vs. 3 was 0.83 [95% confidence interval (CI) 0.76-0.90], with a sensitivity of 61.3% and a specificity of 86.8. The AUC for the discrimination between patients with uncomplicated and complicated PAA was 0.77 (95% CI 0.68-0.86) and the cut-off point was 25.90 pg/mL, with a sensitivity and specificity of 84.6% and 65.6%, respectively. CONCLUSIONS Serum IL-6 has a good performance in discerning between complicated and uncomplicated PAA. A score including clinical and radiological variables may increase the diagnostic performance of this molecule.

Abstract
ABSTRACT A new foliar disease on coffee leaves was observed in Mindanao, Philippines, in 1996. The symptoms appeared as large circular or irregularly shaped necrotic areas with small circular necrotic spots (1 mm or less in diameter) usually found around the periphery of the large necrotic areas. Rhizoctonia solani was consistently isolated from these diseased coffee leaves. Isolates obtained were multinucleate (3 to 12 nuclei per hyphal cell), had an optimum temperature for hyphal growth at 25 degrees C, prototrophic for thiamine, and anastomosed with tester isolates belonging to R. solani anastomosis group 1 (AG-1). Mature cultures on potato dextrose agar (PDA) were light to dark brown. Sclerotia, light brown to brown, were formed on the surface of PDA and covered the whole mature colony culture. Individual sclerotia often aggregated into large clumps (3 to 8 mm in diameter) and their color was brown to dark brown. In pathogenicity tests, isolates from coffee caused necrotic symptoms on coffee leaves, whereas isolates of AG-1-IA (not isolated from coffee), 1-IB, and 1-IC did not. The results of analyses of restriction fragment length polymorphism of ribosomal DNA internal transcribed spacer, random amplified polymorphism DNA, and fatty acid profiles showed that R. solani isolates from coffee are a population of AG-1 different from AG-1-IA, 1-IB, and 1-IC. These results suggest that R. solani isolates from coffee represent a new subgroup distinct from AG-1-IA, 1-IB, and 1-IC. A new subgroup ID (AG-1-ID) is proposed.
