RESUMEN
Primary non-refluxing megaureter (PMU) is a congenital dilation of the ureter which is not related to vesicoureteral reflux, duplicated collecting systems, ureterocele, ectopic ureter, or posterior urethral valves and accounts for 5 to 10% of all prenatal hydronephrosis (HN) cases. The etiology is a dysfunction or stenosis of the distal ureter. Most often PMU remains asymptomatic with spontaneous resolution allowing for non-operative management. Nevertheless, in selective cases such as the development of febrile urinary tract infections, worsening of the ureteral dilatation, or reduction in relative renal function, surgery should be considered. CONCLUSION: Ureteral replantation with excision of the dysfunctional ureteral segment and often ureteral tapering is the gold-standard procedure for PMU, although endoscopic treatment has been shown to have a fair success rate in many studies. In this review, we discuss the natural history, follow-up, and treatment of PMU. WHAT IS KNOWN: ⢠PMU is the result of an atonic or stenotic segment of the distal ureter, resulting in congenital dilation of the ureter, and is frequently diagnosed on routine antenatal ultrasound. WHAT IS NEW: ⢠Most often, PMU remains asymptomatic and clinically stable, allowing for non-operative management. ⢠Nevertheless, since symptoms can appear even after years of observation, long-term ultrasound follow-up is recommended, even up to young adulthood, if hydroureteronephrosis persists. ⢠Ureteral replantation is the gold standard in case surgery is needed. In selected cases, however, HPBD could be a reasonable alternative.

BACKGROUND: Obesity and kidney damage have been closely linked in adults, but little is still known in childhood. OBJECTIVE: To identify predictors of kidney damage in children with metabolically healthy (MHO) and metabolically unhealthy (MUO) obesity phenotypes. METHODS: We retrospectively examined 396 children with obesity (mean age 10.72 ± 2.71 years, body mass index-standard deviation score, BMI-SDS, 2.23 ± 0.57) stratified according to metabolic phenotypes. Kidney damage was defined as the presence of reduced estimated glomerular filtration rate (eGFR < 90 mL/min/1.73m2) and/or albuminuria (≥ 30 mg/g urinary creatinine). RESULTS: Kidney damage was found in 20.9% of the study population. Children with kidney damage had higher BMI-SDS, homeostasis model assessment of insulin resistance (HOMA-IR), and inflammation markers levels and increased prevalence of non-alcoholic fatty liver disease (NAFLD) than those without kidney damage (all p < 0.005). MUO and MHO subjects had respectively an odds ratio (OR) to show kidney damage of of 1.92 (95%CI:1.22-3.01; p = 0.005) and 1.05 (95%CI:1.00-1.09; p = 0.028) after adjustments. Moreover, we found that only HOMA-IR was closely associated to kidney damage in MUO group (OR = 2.07;95%CI:1.20-3.57; p = 0.007), while HOMA-IR (OR = 1.15;95%CI:1.02-1.29; p = 0.011) and uric acid (OR = 1.15;95% CI:1.02-1.30; p = 0.010) were the only significant risk factors for kidney damage in MHO group. CONCLUSION: An increased risk of kidney damage has been observed in children with obesity and in particular in those with MUO phenotype. As their role on kidney function, HOMA-IR should be monitored in MUO children and both HOMA-IR and uric acid in MHO children.

Combination therapy (CT) (desmopressin plus oxybutynin) has been considered for the treatment of monosymptomatic nocturnal enuresis (MNE). We designed our study with the aim to evaluate the response rate to CT compared with desmopressin alone (primary outcome) and to identify factors associated with the response to CT (secondary outcome). We prospectively enrolled children with MNE with absent/partial response after 3 months of evening treatment with 240 mcg of desmopressin. We defined the response rate to CT compared with desmopressin alone according to the standardization of terminology document of the International Children's Continence Society: no-response, < 50% reduction; partial response, 50 to 99% reduction; and complete response, 100% reduction of wet nights. Both partial response and complete response to CT were clustered for the analyses of this manuscript. The enrolled children treated with 240 mcg/evening of desmopressin had also an additional evening administration of 0.3 mg/kg oxybutynin. A follow-up was scheduled at 3 and 6 months after the beginning of CT. At 3 months, oxybutynin dose was augmented to 0.5 mg/kg in case of absent/partial response to CT. Nocturnal diuresis was measured in 5 wet nights prior the beginning of therapy with desmopressin. Nocturnal polyuria (NP) was defined as nocturnal urine production > 130% of the expected bladder capacity. All patients with constipation were treated with macrogol. We enrolled 81 children (35.8% females) with a mean age of 8.4 ± 2.3 years. Seventy-eight patients completed the follow-up. After the CT, 59/78 (75.6%) patients showed an improvement of the response with CT compared with desmopressin alone. At multivariate analysis, both NP in more than 1 night (OR = 8.5; 95% CI, 1.4-51.6; p = 0.02) and absence of constipation (OR = 7.1; 95% CI, 1.6-31.0; p = 0.009) resulted significant after Bonferroni correction. CONCLUSIONS: CT determines an improvement of response compared to therapy with desmopressin alone in 75.6% of patients. Significant predictive factors of response to CT were presence of NP and absence of constipation. WHAT IS KNOWN: ⢠Combination therapy (CT) (desmopressin plus anticholinergic drug) has been described as a therapeutic option for patients with monosymptomatic nocturnal enuresis (MNE) not responding to desmopressin alone as first-line treatment. ⢠Variable protocols and variable combination of drugs have been described with a response rate ranging from 44 to 76%. WHAT IS NEW: ⢠We found that 59 patients (75.6%) treated with evening administration of 240 mcg of sublingual desmopressin plus 0.3-0.5 mg/kg of oxybutynin had an improvement of response compared to treatment with desmopressin alone. ⢠We add evidence that presence of frequently recurring nocturnal polyuria and absence of constipation are predictors of response to CT.

OBJECTIVES: Chronic inflammation plays a central role in the etiology of endothelial damage. Endothelial dysfunction (ED) is the inability of the artery to dilate in response to an endothelial stimulus. We assessed the ED by measuring the reactive hyperaemia index (RHI) and the flow-mediated dilation (FMD) in a cohort of pediatric patients affected by inflammatory bowel disease (IBD) and comparing these parameters to a group of healthy controls (HC). METHODS: Forty-one patients were consecutive enrolled. ED was evaluated by both the plethysmographic RHI method and the measurement of the FMD of brachial artery after occlusion of the blood flow. Differences between patients and controls were assessed by the Mann-Whitney test. In each patient with IBD, the main inflammation markers were detected and correlated to RHI and FMD by a linear regression test. RESULTS: We enrolled 26 (59%) patients with IBD and 18 (41%) HC. When comparing FMD value at diagnosis it was significantly lower in IBD patients than in HC (Pâ=â0.04). This result was confirmed at follow-up, when this difference became even more significant (Pâ=â0.004). A significant indirect correlation was found between FMD and fecal calprotectin (r: 0.17; Pâ=â0.04). No differences were found when comparing RHI. CONCLUSIONS: Our results suggest that inflammation could lead to ED assessed by ultrasound FMD. These data were not confirmed by RHI; however, this could be due to the lack of a standardized pediatric cut-off. More studies are necessary to confirm our data.

The main advantage of the laparo-assisted transanal endorectal pull-through technique (LA - TERPT) for Hirschsprung Disease (HD) is the respect to the rectal-anal anatomy. Postoperative complications have been observed recently. The present study aims to determine how often these postoperative complications occur in these patients. From January 2009 to December 2018, a retrospective analysis was conducted on 36 children (25 males) with HD who underwent LA-TERPT. Data were collected on the age of diagnosis and surgery, sex, the presence of other pathologies, and cases of enterocolitis. In all cases, anorectal manometry (ARM) was performed to evaluate the anal tone. The median age at diagnosis was 2 months and the mean age at surgery was 5 months. Nine related pathologies were identified: five cases of Down syndrome, one case of hypertrophic stenosis of the pylorus, atresia of the esophagus, polydactyly, and anorectal malformation. A patient with total colonic aganglionosis was identified through laparoscopic serummuscular biopsies. Enterocolitis was diagnosed in 7 cases before and 6 after surgery. At follow-up, the complications recorded were: 5 cases of constipation (treated with fecal softeners), one case of anal stenosis (patient with anorectal malformation), 16 cases of soiling (treated with enemas) and 1 child with fecal incontinence (treated with a transanal irrigation system). The ARM was performed in all 36 cases and showed normal anal tone, except for one case with anal hypotonia. LA-TERPT is an important surgical technique for HD. According to the literature, soiling is the most main complication after HD surgery, probably due to "pseudo-incontinence" with normal anal sphincter tone.

INTRODUCTION: Pilonidal sinus is a condition that causes inflammation and abscesses in the sacral region and affects adolescents and young adults. The etiology of this condition remains controversial. CASE PRESENTATION: A six year old boy was observed to have an orifice in the frontonasal region which contained hair. He had two previous infections which were treated with antibiotics. Magnetic Resonance Imaging showed no cranial malformations. Surgery was performed under general anesthesia and the pilonidal sinus was completely excised. At follow-up the child was in good health. CLINICAL DISCUSSION: This case in a child with a frontonasal skin anomaly highlights that skin anomalies may be a cause of pilonidal sinus. CONCLUSION: Skin malformations can be the underlying cause of pilonidal sinus in some cases.
RESUMEN
INTRODUCTION AND IMPORTANCE: Apocrine Hidrocystoma is a relatively rare benign tumour that begins from the apocrine sweat glands of the head and neck. The Authors present a case series of children with urogenital localization. CASES PRESENTATION: Two boys (15 years and 9 years) presented with a small mass on the glans. Another 15-year-old boy presented with a cystic lesion in the right side of the scrotum where he had a previous surgery. The last case, a 17-year-old boy, presented because of a penile cyst of 8 mm. All four had surgical operations because of aesthetic discomfort or problems during micturition. Histological examination showed a diagnosis of apocrine hidrocystoma in all cases. CLINICAL DISCUSSION: This benign tumour rarely affects the urogenital system in children, but when it happens the child can have discomfort and proper treatment is mandatory. CONCLUSION: Surgery is the preferred treatment with a low risk of recurrence.
RESUMEN
This study aimed to report a multicentric national experience about the outcomes of pediatric endoscopic pilonidal sinus treatment (PEPSiT). The medical records of all pediatric patients, aged up to 18 years, who underwent PEPSiT in the period 2019-2021, were retrospectively reviewed. Patients' demographics, operative details, and post-operative outcomes were assessed. A total of 294 patients (182 boys), with median age of 14 years (range 10-18), receiving PEPSiT in the study period, were enrolled. Pilonidal sinus disease (PSD) was primary in 258 (87.8%) and recurrent in 36 (12.2%). The median operative time was 36 min (range 11-120). The median VAS pain score was 0.86 (range 0-3) and the median duration of analgesic use was 27 h (range 12-60). The overall success rate was 95.2% (280/294) and the median time to full healing was 23.4 days (range 19-50). Six/294 (2.0%) patients developed Clavien 2 post-operative complications. The recurrence rate was 4.8% (14/294) and all recurrences were re-operated using PEPSiT. Redo-surgery for wound debridement was performed in one (0.3%) patient with late healing. On multivariate analysis, hirsutism and typology of sinus (pits ≥ 2, paramedian and more proximal to the anus) were predictors of PSD recurrence (p = 0.001). To date, this is the largest series of PEPSiT published in the pediatric population. The outcomes reported after a 3 years experience confirm that PEPSiT is a safe, effective, and real minimally invasive procedure to treat adolescents with PSD. It provides patients quick and painless recovery, satisfactory success, and high quality of life.

Childhood obesity and its related comorbidities have become major health issues over the last century. Among these comorbidities, cardiovascular diseases, especially hypertension, are the most significant. Recently, a polymorphism affecting the activity of lanosterol synthase has been associated with an increased risk of hypertension in adolescents. In this study, we aimed to investigate the effect of LSS rs2254524 polymorphism on blood pressure in children and adolescents with obesity. We enrolled 828 obese children aged 6-17 years. Subjects carrying the A allele showed higher rates of systolic and diastolic stage I hypertension and stage II hypertension. Carriers of the A allele showed a 2.4-fold (95% C.I. 1.5-4.7, p = 0.01) higher risk for stage II hypertension and a 1.9-fold higher risk for stage I hypertension (95% C.I. 1.4-2.6, p < 0.0001). The risk was independent of confounding factors. In conclusion, LSS rs2254524 worsens the cardiovascular health of children and adolescents with obesity, increasing their blood pressure.

OBJECTIVE: Leptin plays a key role in the regulation of body weight and other endocrine systems. Recently, impairment of leptin gene transcription due to genetic variations in a long noncoding RNA (lncOb) has been described. This retrospective study aims to characterize the clinical and metabolic phenotype of children and adolescents with obesity who were homozygous for the lncOb rs10487505 leptin lowering allele. METHODS: Enrolled children underwent an anthropometrical evaluation, biochemical assessment, and genotyping for lncOb rs10487505. Plasma leptin levels were assessed in 150 participants. A total of 434 patients were included and divided into two groups according to rs10487505 recessive inheritance (CC vs. GG/GC). RESULTS: Children who were homozygous for the C allele showed higher fasting insulin (p = 0.01), homeostasis model assessment of insulin resistance (p = 0.01), lower whole-body insulin sensitivity index (p = 0.02), and lower disposition index (p = 0.03). Moreover, CC patients presented with a higher prevalence of prediabetes (9.3% vs. 3.4%, p = 0.04) and a 2.9-fold (95% CI: 1.1-7.9, p = 0.04) higher risk of prediabetes compared with G-carriers independently from confounders. Leptin plasma levels were significantly lower in the CC group (p = 0.002). Hormone levels correlated with BMI z score (r = 0.19, p = 0.04), fasting insulin (r = -0.34, p < 0.0001), homeostasis model assessment of insulin resistance (r = -0.33, p < 0.0001), and disposition index (r = 0.20, p = 0.04). CONCLUSIONS: The lncOb rs10487505 polymorphism affects leptin circulating levels, worsens insulin resistance, and heightens the risk of prediabetes in children and adolescents with obesity.

Gonadal and extragonadal pediatric germ cell tumors (GCTs) are rare neoplasms with different clinical behavior. Although surgery and cisplatin-based chemotherapy are resolutive in most cases, some patients do not respond to chemotherapy and have a worse outcome. Microsatellite instability (MSI) was correlated to resistance to chemotherapy and sensitivity to immunotherapy in different neoplasms. A series of 21 pediatric GCTs were tested by immuno-histochemistry and PCR to evaluate MSI status. Next generation sequencing was applied to further evaluate cases with discordant results between immunohistochemistry and PCR. Twenty-one cases of pediatric GCT were included in the series. The mean age ranged between 1 and 10 years. Nine cases were gonadal GCTs and the remaining 12 were extra-gonadal GCTs. By immunohistochemistry, one case showed a deficit of Mismatch repair (MMR) proteins. This case was a 1-year-old children affected by gonadal yolk sac tumor. However, all cases resulted microsatellite stable (MSS) by PCR and NGS. MSI was not detected in our series of pediatric GCTs, as well as the data present in literature about adult patients with GCTs. Molecular techniques could have a role to confirm the MSI status in case of dMMR by immunohistochemistry.
RESUMEN
Celiac disease (CD) is a chronic inflammatory disease of the small bowel that occurs with the ingestion of gluten, found in several grains products. Although HLA-DQ2 variant is required for the gluten-derived peptide gliadin presentation by antigen-presenting cells to T-cells, non-HLA genetic factors account for the majority of heritable risk. Several genome-wide association studies have identified susceptibility loci for CD on chromosome 1. Cells of the immune system express the cannabinoid receptor type 2 (CB2), a plasma-membrane receptor activated by both endogenous and exogenous cannabinoids. Consistent data evidence that CB2 is linked to a variety of immune functional events and that, in the course of an inflammatory process, an increased number of receptors becomes available for activation. The cannabinoid receptor type 2 gene (CNR2; GeneID1269) maps on 1p36.11. In order to investigate the possible involvement of CB2 in CD establishment, immunohistochemistry toward CB2 receptor and CD4+ cells in small bowel biopsies from celiac children and association analysis, through TaqMan assay, of a CNR2 common missense variant, rs35761398 (CAA/CGG), resulting in the aminoacidic substitution of Glutamine at codon 63 with Arginine (Q63R), in a cohort of 327 South Italian children have been performed. We observed in this study that CB2 is up-regulated in CD small bowel biopsies and CNR2 rs35761398 is significantly associated with CD (χ(2) = 37.064; d.f. 1; p = 1.14 × 10(-9)). Our findings suggest a role of CB2 in CD. The Q63R variant, increasing more than six-fold the risk for CD susceptibility, might eventually represent a novel molecular biomarker for CD risk stratification. Indeed, we provide here further evidence that CB2 receptor plays a critical role in autoimmunity susceptibility and indicates that it represents a molecular target to pharmacologically modulate the immune components in CD.

Infant dyschezia is a functional gastrointestinal disorder that occurs in children less than nine months of age. This disorder causes much anxiety among parents who consult different physicians when suspecting major intestinal problems. The aim of this study is to verify whether infant dyschezia involves an anatomic abnormality (redundancy) of the colon. In this retrospective study (48 months) we analyzed all the children younger than 9 months who came to our attention through the suspicion of gastrointestinal abnormality (Hirschsprung's disease, anorectal malformations, colonic disorders or constipation). They all had a complete medical history, clinical examination and diagnostic tests, such as blood samples, suction rectal biopsy, a study of stool characteristics and, finally, a contrast enema. In cases with infant dyschezia, different colonic sizes and rectosigmoid length were measured, which created a ratio with the diameter of the second lumbar vertebra. These values were compared with those reported in the literature as normal for the age of one year. Of the 24 patients evaluated (mean age 4 months), 9 were excluded for different diagnoses (aganglionic megacolon, hypothyroidism, constipation). The comparison of the ratios obtained in the remaining 15 cases showed a significantly higher rectosigmoid length (redundancy) in children with dyschezia, 18.47 vs. 9.75 (p < 0.001). The rectosigmoid redundancy, a congenital anomaly already reported as a cause of refractory constipation, may be present in children with infant dyschezia.
RESUMEN
Since laparoscopy has been proposed in the management of the nonpalpable testis (NPT), this technique has been widely diffused among pediatric surgeons and urologists, but its application is still debated. We conducted a retrospective review to highlight how diagnostic and surgical indications for laparoscopy are selective and should be targeted to individual patients. From 2015 to 2019, 135 patients with NPT were admitted to our surgical division. Of these, 35 were palpable on clinical examination under anesthesia and 95 underwent laparoscopy. The main laparoscopic findings considered were: intra-abdominal testis (IAT), cord structures that are blind-ending, completely absent, or entering the abdominal ring. The patients' mean age was 22 months. In 48 cases, an IAT was found, and 42 of these underwent primary orchidopexy while 6 had the Fowler-Stephens (FS) laparoscopic procedure. Of the first group one patient experienced a testicular atrophy while two a reascent of the testis. In the FS orchidopexy group, one patient had testicular atrophy. Cord structures entering the internal inguinal ring were observed in 35 children, and all were surgically open explored. In 3 cases of these, a hypotrophic testis was revealed and an open orchidopexy was executed. In the remaining the histological examination revealed viable testicular cells in four patients and fibrosis, calcifications, and hemosiderin deposits in the others. Eleven patients presented with intrabdominal blind-ending vessels and one a testicular agenesia. A careful clinical examination is important to select patients to submit to laparoscopy. Diagnostic laparoscopy, and therefore, the anatomical observation of the testis and cord structures are strictly related to develop a treatment plan. In IAT, many surgical strategies can be applied with good results. Laparoscopy offers a concrete benefit to the patient.
RESUMEN
Puberty is a critical process characterized by several physical and psychological changes that culminate in the achievement of sexual maturation and fertility. The onset of puberty depends on several incompletely understood mechanisms that certainly involve gonadotropin-releasing hormone (GnRH) and its effects on the pituitary gland. The role of makorin ring finger protein 3 (MKRN3) in the regulation of pubertal timing was revealed when loss-of-function mutations were identified in patients with central precocious puberty (CPP), which to date, represent the most commonly known genetic cause of this condition. The MKRN3 gene showed ubiquitous expression in tissues from a broad spectrum of species, suggesting an important cellular role. Its involvement in the initiation of puberty and endocrine functions has just begun to be studied. This review discusses some of the recent approaches developed to predict MKRN3 functions and its involvement in pubertal development.

The COVID-19 pandemic has had a huge impact on children's lifestyle and eating behaviour, resulting in an increase of obesity prevalence. The CEBQ (Children's Eating Behaviour Questionnaire) is a validate questionnaire that investigates children's eating behaviour. Knowing the psychological consequences of daily routine disruption during lockdown, we evaluated the changes in eating behaviours in a paediatric cohort before and during the lockdown period through the evaluation of the Italian version of the CEBQ. We prospectively enrolled children attending the pediatric clinic of the University of Campania 'Luigi Vanvitelli'. All parents answered the parent-report version of the CEBQ before lockdown containment. During lockdown, the second survey was carried out by telephone call. The study sample included 69 children. Food responsiveness and emotional overeating subscales showed higher scores during lockdown compared to data before lockdown (p = 0.009 and p = 0.001, respectively). Conversely, desire to drink and satiety responsiveness showed lower scores at follow-up (p = 0.04 and p = 0.0001, respectively). No differences were observed for slowness in eating and enjoyment of food. Delta changes were higher in normal-weight children compared to children with obesity (p = 0.02). Our results confirm that containment measures during the COVID-19 pandemic have acted as triggers on certain eating behaviors that mostly predispose to an obesogenic manner.
RESUMEN
Pediatric obesity is associated with an increased risk of morbidity during childhood. Alongside the well-known metabolic syndrome, during the last decades scientific research has deeply investigated the risk of sleep breathing disorders. Among them, obstructive sleep apnea (OSA) commonly affects children with obesity. The presence of OSA heightens the risk of metabolic impairment and weight gain. Therefore, it deserves specific treatment. However, polysomnography (PSG) is not always available in clinical settings, and alternative diagnostic tools are needed. This study aimed to investigate the predictivity of the pediatric sleep questionnaire (PSQ) for moderate-to-severe OSA diagnosis. Children and adolescents with obesity and suspected OSA with available full-night cardiorespiratory PSG were retrospectively enrolled. Receiver operating curve analysis was performed to test the ability of PSQ in predicting moderate-to-severe OSA (AHI > 5 episode/h). The final sample included 60 children and adolescents. The PSQ showed a good area under the curve (AUC) of 0.88 (95% CI 0.78−0.98, p < 0.0001). Moreover, a value above or equal to 0.65 showed an 80% sensitivity and 100% specificity for moderate and severe OSA. These findings suggest that PSQ might be used in clinical settings with limited access to PSG for stratifying disease severity and for selecting children with urgent need of sleep study.
RESUMEN
Three new equations for calculating the estimated basal serum creatinine (ebSCr) in hospitalized children have been developed: the simplified acute kidney injury (AKI) baseline creatinine (ABC) equation which considered only age in the formula; the equation including age and minimum creatinine (Crmin) within the initial 72 h from hospitalization (ABC-cr); and the equation including Crmin and height, weight, and age as squared values (ABC-advanced). We aimed to test the diagnostic performance of the ABC, ABC-cr and ABC-advanced equations in diagnosing AKI in 163 prospectively enrolled children with type 1 diabetes mellitus (T1DM) onset. We considered measured basal serum creatinine (mbSCr), the creatinine measured 14 days after T1DM onset. AKI was defined by the highest/basal serum creatine (HC/BC) ratio > 1.5. On the basis of the mbSCr, the AKI was diagnosed in 66/163 (40.5%) patients. This prevalence was lower than the prevalence of AKI diagnosed on the basis of ABC ebSCr (122/163 patients; 74.8%) (p < 0.001) and similar to the prevalence of AKI diagnosed on the basis of ABC-cr ebSCr (72/163 patients; 44.2%) (p = 0.5) and to the prevalence of AKI diagnosed on the basis of ABC-advanced ebSCr (69/163; 42.3%) (p = 0.73). AKI determined using ABC ebSCr, ABC-cr ebSCr and ABC-advanced ebSCr showed, respectively, 63.5% (kappa = 0.35; p < 0.001), 87.7% (kappa = 0.75; p < 0.001), and 87.1% (kappa = 0.74; p < 0.001) agreement with AKI determined using mbSCr. Using the HC/BC ratio calculated on the basis of mbSCr as gold standard, for Bland−Altman plots the HC/BC ratio calculated on the basis of ABC formula presented higher bias and wider limits of agreement compared with the HC/BC ratio calculated on the basis of ABC-cr and ABC-advanced formulas. In the receiver−operating characteristics (ROC) curve analysis the HC/BC ratio calculated on the basis of ABC ebSCr presented lower area under the ROC curve (AUROC) (AUROC = 0.89; 95%CI: 0.85−0.95; p < 0.001) compared with HC/BC ratio calculated on the basis of ABC-cr (AUROC = 0.94; 95%CI: 0.91−0.98; p < 0.001) or ABC-advanced ebSCr (AUROC = 0.914; 95%CI: 0.91−0.97; p < 0.001). In both Bland−Altman plots and ROC curve analysis, the ABC-cr and ABC-advanced formulas performed similarly. In conclusion, the ABC-cr and ABC-advanced formulas present very good diagnostic performance toward AKI identification in a population of children with T1DM onset.
RESUMEN
Fowler-Stephens Laparoscopic Orchiopexy (FSLO) permits the mobilization of Intra-Abdominal Testis (IAT) to the scrotal position after spermatic vessel ligation. We reported our experience of FSLO for IAT. The charts of all boys who underwent a FSLO were retrospectively reviewed. Data were analysed for demographic data, procedure, complications and follow-up results. From January 2008 to June 2016, 160 laparoscopies for Non Palpable Testis (NPT) were performed at a mean age of 3,2 years. 61% of patients had a right NPT, while 6% were bilateral. In 64 cases, an IAT was found: 20 were managed by FSLO with a two-stage procedure in 11 patients. There were no differences in hospitalisations; one patient had a prolonged ileus. Follow-up ranged from 1 to 8 years. Of the 20 patients who underwent FSLO, testicular atrophy developed in three; the remaining testes were in the scrotal position, with normal consistency. FSLO was applied in 31% of IAT. The overall success rate of the technique was 85 %. The percentage of atrophy associated after spermatic vessels interruption appears to provide a good chance of testicular survival.

Laparoscopic surgery has been one of the most common procedures for abdominal surgery at pediatric age during the last few decades as it has several advantages compared to laparotomy, such as shorter hospital stays, less pain, and better cosmetic results. However, it is associated with both local and systemic modifications. Recent evidence demonstrated that carbon dioxide pneumoperitoneum might be modulated in terms of pressure, duration, temperature, and humidity to mitigate and modulate these changes. The aim of this study is to review the current knowledge about animal and human models investigating pneumoperitoneum-related biological and histological impairment. In particular, pneumoperitoneum is associated with local and systemic inflammation, acidosis, oxidative stress, mesothelium lining abnormalities, and adhesion development. Animal studies reported that an increase in pressure and time and a decrease in humidity and temperature might enhance the rate of comorbidities. However, to date, few studies were conducted on humans; therefore, this research field should be further investigated to confirm in experimental models and humans how to improve laparoscopic procedures in the spirit of minimally invasive surgeries.
