Abstract
We present the case of a 6-year-old girl who presented with alterations in the voiding stream. On physical examination, a very small urethral meatus was identified at the expense of a membrane. The renovesical ultrasound showed no alterations. An uroflowmetric study was performed, showing a bladder outlet obstruction pattern. The urethral meatus was calibrated and a ventral meatotomy was performed. The histological study of the resected membrane showed a transitional urethral mucosa with chronic focal inflammation and discrete hyperplasia. The patient evolved favorably, with resolution of the symptoms and no notable complications. This is, to the best of our knowledge, the first reported case with a histological study of a congenital meatal urethral stenosis. In the presence of lower urinary tract obstruction, this entity should be considered in the differential diagnosis. Surgical treatment is curative.

Abstract
This study aimed to analyze the diagnostic performance of serum CA-125 in acute appendicitis (AA). This review was registered in PROSPERO (CRD42023450988). We included prospective and retrospective original clinical studies evaluating the diagnostic performance of serum CA-125 in AA. A search was conducted in PubMed, Web of Science, Scopus, and OVID. Search terms and keywords were: (appendicitis OR appendectomy) AND (CA-125 OR CA125). Two independent reviewers selected the articles and extracted relevant data. Methodological quality was assessed using the QUADAS-2 index. A synthesis of the results, standardization of the metrics, and three random-effect meta-analyses were performed. Five studies with data from 533 participants (including 219 patients with a confirmed diagnosis of AA and 107 controls) were included in this review. The random-effect meta-analysis of serum CA-125 (AA vs controls) included 3 articles (125 AA and 70 controls) and resulted in a non-significant mean difference [95% CI] of - 6.80 [- 20.51, 6.92] U/mL (p = 0.33). The meta-analysis by subgroups that included only male patients resulted in a significant mean difference [95% CI] of 3.48 [0.46, 6.49] U/mL (p = 0.02). Although serum CA-125 does not appear to be a good overall marker for the diagnosis of AA, our subgroup analyses show that this marker could be useful for diagnosing AA in males. It also appears to be a potentially useful tool for discriminating complicated and uncomplicated AA. However, the limited number of included studies precludes drawing generalizable conclusions. Future prospective studies focused on males and in its potential ability to discriminate between complicated and uncomplicated AA are required.Registration. PROSPERO (CRD42023450988).

Abstract
Although Blastocystis sp. has been classically considered a commensal parasite with limited pathogenicity, recent studies suggest that its pathogenic potential is high. We report the case of a 9-year-old Spanish male who presented with peritonitis secondary to acute appendicitis with abundant intra-abdominal turbid-free fluid. A standard appendectomy was performed, and a sample of the fluid was taken for microbiological culture. Multimicrobial flora was isolated in peritoneal fluid culture. The antibiotic resistance study showed that all the microorganisms were sensitive to meropenem. On the 5th postoperative day, a control blood test showed relative eosinophilia and a persistently elevated C-reactive protein. A stool parasitological study showed abundant cysts morphologically compatible with Blastocystis hominis . The hematoxylin & eosin and Giemsa study identified abundant parasitic cysts in the appendix. The patient evolved favorably and is currently asymptomatic and under follow-up. Regarding acute appendicitis, there is only one report in the literature of peritonitis of appendiceal origin associated with Blastocystis sp. In conclusion, although infrequent, parasitosis should be considered as a potential etiological agent of acute appendicitis, even in nonendemic areas. Relative eosinophilia or persistently elevated acute phase reactants despite adequate antibiotic coverage should help to establish diagnostic suspicion.

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
Rectosigmoid solitary juvenile polyps are benign lesions, relatively frequent in childhood. The clinical debut of a pediatric polyp with bleeding is relatively frequent, but there are very few reports of rectal prolapse of polyps. We present the case of a 7-year-old female patient with no previous history who presented with rectal prolapse of a polyp with acute bleeding. An urgent endoscopic examination was performed and 2 rectosigmoid polypoid lesions were found and resected. The anatomopathological study showed that these were 2 hamartomatous polyps with mild dysplasia. The patient is asymptomatic and is being followed up. The literature concerning rectal prolapse of polyps in the pediatric population is scarce. In a pediatric patient with a rectal prolapse, this entity should be considered in the differential diagnosis.

Abstract
A 78-year-old woman with hypertrophic cardiomyopathy underwent a septal myomectomy and valve replacement. In the immediate postoperative period she developed shock of mixed etiology and died. At autopsy, hepatomegaly and splenomegaly were identified, with PAS and Giemsa positive intracellular ceroid granular deposits. Sea-blue histiocytosis is an extremely rare, chronic and benign deposit disease. It is characterized by hepatosplenomegaly, thrombocytopenia and lymphadenopathy. The presence of ceroid substance in granules in PAS and Giemsa stains should establish the diagnosis of suspicion.

Pop-off mechanisms as renoprotective mediators in children with posterior urethral valves: A systematic review and meta-analysis. J Pediatr Urol 2024; 20:57-66.

Abstract
BACKGROUND Pop-off mechanisms are potential pressure-relieving mediators in patients diagnosed with posterior urethral valves (PUV). This systematic review aimed to synthesize the existing evidence regarding the protective effect of pop-off mechanisms on renal function in children with PUV. METHODS We conducted a systematic review of the literature that involved an extensive search in the main databases of the medical bibliography. Three independent reviewers selected the relevant articles. Methodological quality was rated using the Newcastle Ottawa Scale index. We used random meta-analyses to compare different outcomes (serum creatine, Nadir serum creatinine, and Chronic Kidney Disease) between children with PUV and pop-off mechanisms and those with PUV without pop-off mechanisms. RESULTS 10 studies with data from 896 participants were included in this review. Seven articles reported serum creatinine values for each group and 3 of them found significant differences between groups. The random-effects meta-analysis for serum creatinine showed significant lower mean (diff = -52.88 μmol/L [95 % CI -73.65 to -32.11]) in the group of children with pop-off mechanisms, and the random-effects meta-analysis for Nadir serum creatinine showed a marginally significantly lower mean in the group of children with pop-off mechanisms (diff = -12.00 μmol/L [95 % CI -24.04 to 0.04]). The random-effect meta-analysis for Chronic Kidney Disease resulted in a significant risk reduction for the group of children with pop-off mechanisms (odds ratio = 0.48 [95 % CI 0.23 to 0.98]). CONCLUSIONS Children with PUV and pop-off mechanisms show better renal function and lower risk of Chronic Kidney Disease than those with PUV without pop-off mechanisms suggesting these mechanisms may act as renoprotective mediators. The high heterogeneity between studies in the assessment of renal function and long-term outcomes calls for a cautious interpretation of these findings. Future studies that stratify by different types of pop-off mechanisms and use standardized metrics, such as Nadir creatinine, are needed.

Abstract
OBJECTIVES This study aimed to analyze the diagnostic performance of urinary 5-Hydroxyindoleacetic Acid (5-HIAA) in acute appendicitis (AA). METHODS This review was registered in PROSPERO (CRD42023399541). We included prospective or retrospective original clinical studies evaluating the diagnostic performance of 5-HIAA in AA. A search was conducted in PubMed, Web of Science, Scopus and OVID. Search terms and keywords were: (appendicitis OR acute appendicitis) AND (5-HIAA OR 5-Hydroxyindoleacetic acid OR serotonin metabolite). Two independent reviewers selected the articles and extracted relevant data. Methodological quality was assessed using the QUADAS2 index. A synthesis of the results, standardization of the metrics, and a random-effect meta-analysis were performed. Additionally, a coupled forest plot and a diagnostic test accuracy meta-analysis (DTA) were performed. RESULTS Twelve studies with data from 1467 participants (724 patients with a confirmed diagnosis of AA and 743 controls) were included in this review. The random-effect meta-analysis of urinary 5-HIAA (AA vs controls) included 7 articles (352 AA and 258 controls) and resulted in a significant mean difference [95% CI] of 23.30 [15.82-30.77] μmol/L (p < 0.001). The DTA meta-analysis of urinary 5-HIAA included 8 articles and resulted in a pooled sensitivity [95% CI] of 68.6 [44.1-85.9]% and a pooled specificity [95% CI] of 82 [54.7-94.5]%. CONCLUSIONS Although the evidence is heterogeneous and limited, urinary 5-HIAA emerges as a potential non-invasive diagnostic tool for AA. Urinary 5-HIAA does not seem to be a useful biomarker to distinguish between NCAA and CAA. Future prospective studies with a large sample size and a rigorous design are necessary to validate these findings. TRIAL REGISTRATION PROSPERO (CRD42023399541).

Abstract
Multiple variants of classic bladder exstrophy have been described, all of them infrequent. Superior vesical fissure is a mild variant of this pathology in which genital involvement is scarce or absent. To date, there are only isolated reports of this entity. We report a full-term female patient of Arabian descent with a clinical and radiological diagnosis of superior vesical fissure that was surgically corrected in our center with a favorable evolution. Histological study, supported by immunohistochemical techniques, showed squamous and transitional epithelium and discrete chronic inflammation. Our literature review identified 26 reports of superior vesical fissure (including ours), with high heterogeneity in terms of clinical characterization and associated malformations and with only two histological reports. The clinical evolution of the patients reported in the literature was favorable, with lower morbidity and mortality than in classical forms of bladder exstrophy.

Abstract
INTRODUCTION Scientific literature regarding the characterization of lymphocyte subpopulations of the cecal appendix is sparse, with few precedents limited to immunohistochemical techniques. METHODS We conducted a prospective pilot study to characterize lymphocyte subpopulations of the cecal appendix in children. Participants were divided into three groups: (1) patients without histological acute appendiceal inflammation, (2) patients with histological uncomplicated acute appendicitis, and (3) patients with histological complicated acute appendicitis (gangrenous, perforated). A fresh sample of the base of the appendix was taken from all patients and a flow cytometric study was performed. Quantitative variables were compared using Kruskal-Wallis test and Mann-Whitney U test. RESULTS This study included 57 patients divided into Group 1 (n = 5), Group 2 (n = 37), and Group 3 (n = 15). Median values (IQR) of the percentage of B-lymphocytes were 67.8 [66.8-68.1] in group 1, 61.15 [53.74-66.4] in group 2, and 52.1 [33-62.02] in group 3 (p = 0.02). Median values (IQR) of the percentage of NK-lymphocytes were 0.26 [0.2-0.3] in group 1, 0.55 [0.37-0.66] in group 2, and 0.84 [0.35-1.45] in group 3 (p = 0.008). Median values (IQR) of the percentage of T-lymphocytes were 31.9 [31.7-33.1] in group 1, 37.68 [32.15-45.69] in group 2, and 46.9 [37.03-67] in group 3 (p = 0.02). Pair comparisons of groups 2 and 3 also showed significant differences in the percentage of B lymphocytes (p = 0.03) and NK-lymphocytes (p = 0.02). CONCLUSIONS Significant differences in lymphocyte subpopulations were identified according to the histologic grade of the cecal appendix. More specifically, a lower percentage of B-lymphocytes and a higher percentage of T- and NK-lymphocytes were observed in cases of acute appendicitis. These findings must be confirmed and their etiopathogenic, diagnostic, and prognostic implications elucidated in future studies with larger sample sizes.

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.

Abstract
The aim of this study was to analyze the diagnostic performance of Leucine-Rich Alpha-2-Glycoprotein (LRG1) in pediatric acute appendicitis (PAA). We conducted a systematic review of the literature in the main databases of medical bibliography. Two independent reviewers selected the articles and extracted relevant data. Methodological quality was assessed using the QUADAS2 index. A synthesis of the results, standardization of the metrics and 4 random-effect meta-analyses were performed. Eight studies with data from 712 participants (305 patients with confirmed diagnosis of PAA and 407 controls) were included in this review. The random-effect meta-analysis of serum LRG1 (PAA vs control) resulted in a significant mean difference (95% CI) of 46.76 μg/mL (29.26-64.26). The random-effect meta-analysis for unadjusted urinary LRG1 (PAA vs control) resulted in a significant mean difference (95% CI) of 0.61 μg/mL (0.30-0.93). The random-effect meta-analysis (PAA vs control) for urinary LRG1 adjusted for urinary creatinine resulted in a significant mean difference (95% CI) of 0.89 g/mol (0.11-1.66). Conlusion: Urinary LRG1 emerges as a potential non-invasive biomarker for the diagnosis of PAA. On the other hand, due to the high between-study heterogeneity, the results on serum LRG1 should be interpreted with caution. The only study that analyzed salivary LRG1 showed promising results. Further prospective studies are needed to confirm these findings. What is Known: • Pediatric acute appendicitis continues to be a pathology with a high rate of diagnostic error. • Invasive tests, although useful, are a source of stress for patients and their parents. What is New: • LRG1 emerges as a promising urinary and salivary biomarker for the noninvasive diagnosis of pediatric acute appendicitis.

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: The aim of this study was to analyze the diagnostic performance of total platelet count (PC), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) in pediatric acute appendicitis (PAA). Methods: We conducted a systematic review of the literature in the main databases of medical bibliography. Two independent reviewers selected the articles and extracted relevant data. Methodological quality was assessed using the QUADAS2 index. A synthesis of the results, a standardization of the metrics, and four random effect meta-analyses were performed. Results: Thirteen studies including data from 4,373 participants (2,767 patients with confirmed diagnosis of PAA and 1,606 controls) were included. Five studies compared PC, and the meta-analysis including three of them showed a non-significant mean difference of -34.47 platelets/1 × 109/L (95% confidence interval [CI], -88.10 to 19.16). Seven publications compared PLR and the meta-analysis of those studies showed significant mean differences between patients with PAA and controls (dif: 49.84; 95% CI, 25.82-73.85) as well as between patients with complicated and uncomplicated PAA (dif: 49.42; 95% CI, 25.47-73.37). Four studies compared MLR and the meta-analysis including all of them showed a non-significant mean difference of -1.30 (95% CI, -3.52 to 0.92). Conclusions: Although existing evidence is heterogeneous and limited, PLR appears to be a promising molecule for the diagnosis of PAA and for the discrimination between complicated and uncomplicated PAA. Our results do not support the use of PC or MLR as biomarkers in PAA.

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
Peutz-Jeghers syndrome is an autosomal dominant condition characterized by the association of hamartomatous polyps in the digestive tract, mucocutaneous pigmentation, family history, and infrequently tumors of the female genital tract with one of the most characteristic being the gastric-type endocervical adenocarcinoma. We present the case of a 75-year-old woman with a history of gastrointestinal polyps and cancer of the pancreas and breast, diagnosed with Peutz-Jeghers syndrome, who clinically debuted with a primary adnexal tumor. However, on histologic examination it was found to be a gastric-phenotype primary mucinous carcinoma tubal in origin, associated to tubal mucinous metaplasia and secondary ovarian involvement. One of her daughters had a confirmed genetic diagnosis of Peutz-Jeghers syndrome and presented with mucinous metaplasia of the tubal mucosa in the pathological study of a prophylactic hysterectomy specimen. Another of her daughters died from an ovarian juvenile granulosa cell tumor, she did not have a genetic diagnosis of Peutz-Jeghers syndrome. This case intends to highlight the rarity of gastrointestinal-type mucinous carcinomas of the ovary and fallopian tube (similar to gastric-type endocervical adenocarcinoma) in Peutz-Jeghers syndrome and emphasize the importance of genetic counseling of these patients as well as the adequate sampling of surgical specimens for early detection and treatment.

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
Among the causes of acute surgical abdomen, infection of a urachal remnant may go unnoticed despite routine complementary studies. We present three cases in boys aged 11, 6, and 4 years who were brought to the emergency department for right iliac fossa pain, fever, and urinary symptoms. Examination and complementary tests results were compatible with acute complicated appendicitis and were sent to surgery. While in the operating room, appendicitis was excluded and inflammatory changes suggestive of infection of the urachal remnant were documented. Complications of urachal remnants should be considered in the differential diagnosis of acute surgical abdomen, since advanced infection of the urachus may be a cause of confusion. A more accurate presumptive diagnosis can change the therapeutic/surgical approach and follow-up.

Abstract
Nodular fasciitis is a benign soft tissue lesion with rapid fibroblastic or myofibroblastic proliferation, rarely observed in pediatric patients. Here, we present the case of a seven-year-old boy with no relevant medical records, in whom an asymptomatic dorsal tumor was incidentally identified. Magnetic resonance imaging showed a left dorsal paravertebral lesion with hypointensity on T1, hyperintensity on T2, peripheral contrast enhancement, and the so-called fascial tail sign. Complete surgical resection of the lesion was achieved. The histopathological study showed a proliferation of spindle or stellate cells with nuclei without atypia in a myxoid or collagenized stroma. The immunohistochemical profile showed positivity for smooth muscle actin, muscle-specific actin antibody HHF35, and calponin. The lesion was diagnosed as nodular fasciitis, an entity with broad and complex differential diagnosis. Presence of specific radiological signs and adequate immunohistochemical characterization of the lesion help perform an accurate diagnosis.

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
Superficial angiomyxoma is characterized as a benign, slow-growing vascular cutaneous myxoma. A 6-year-old Arab girl with no medical history presented with a vulvar tumor located on the left labia majora. The lesion was present since birth, but it had significantly increased over the last 6 months. She did not have any associated symptoms. Physical examination revealed an exophytic tumor of the left labia majora, which measured 5 cm in its major axis. Doppler ultrasound study showed a mass with abundant arterial and venous vascularization, and magnetic resonance imaging showed a highly vascular contrast-enhanced mass with well-delimited margins, which depended on the labia majora. A macroscopically complete resection was performed, achieving a tension-free primary closure. Histologically, the lesion was characterized as a well-demarcated superficial tumor with thin-walled vessels and myxoid stroma, S100 (−), CD34 (+), vimentin (+), and actin (+). The final histopathological diagnosis was superficial angiomyxoma. The literature review of this entity in the pediatric population shows a predominance of this lesion in the vulvar location. Local recurrence has been described. Loss of PRKAR1A expression may be involved in the pathogenesis of superficial angiomyxoma.

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 cytomegalovirus (CMV) infection can cause severe neurological sequelae or even fetal death. We present a 17-year-old pregnant woman with fetal CMV infection, leading to voluntary termination of pregnancy. Fetopsy demonstrated a brainstem hemorrhage and focal polymicrogyria. CMV inclusions were observed in the lung, liver, thyroid, pancreas, kidneys, adrenal, placenta, and central nervous system. Intracranial hemorrhage is a rare finding in the context of congenital CMV infection, with isolated brainstem hemorrhage being an exceptional form of presentation. Polymicrogyria appears to be a more frequent finding, although its actual incidence is unknown. Future studies are needed to determine the causal association.

Abstract
Background: Proteus syndrome is characterized by a progressive segmental or patchy growth of bone, skin, adipose tissue, and central nervous system, associated with a wide range of neoplasms, pulmonary pathology, and thrombotic risk. The main histological findings are diffuse patchy overgrowth of skin and subcutaneous tissue, plantar cerebriform connective tissue nevus, and ossification defects. Case report: We present a patient that met the clinical and histological criteria necessary for the diagnosis of the disease. He required multiple surgical interventions, including amputation of the right foot. Genetic evaluation confirmed an AKT1 mutation. Discussion: CLOVES syndrome, neurofibromatosis 1 or PTEN hamartoma tumor syndrome are partially superimposable entities to Proteus syndrome and may generate diagnostic doubt. Although the clinical criteria and histologic findings are indicative, the diagnostic confirmation of this entity is genetic.
