Incidental finding of thyroglossal duct cyst in a neonate during endotracheal intubation: a case report.

BACKGROUND: Thyroglossal Duct Cyst (TDC) is a common lesion of the midline neck, originating from an incomplete involution of the thyroglossal duct. It is typically observed in pre-scholar patients and surgery is the treatment of choice to prevent infections. Here reported a case of incidental diagnosis in a newborn patient. CASE PRESENTATION: a 3-week-old male baby was admitted to our hospital for weight loss and projectile vomits after breastfeeding. After a diagnosis of hypertrophic pyloric stenosis, the baby underwent pyloromyotomy. During the endotracheal tube placement, the anesthetist noticed the presence of a midline neck mass. The suspect of TDC was confirmed by an intraoperative ultrasound, so, despite the age of the patient, we proceeded with the excision of the lesion according to Sistrunk's procedure to avoid future complications and anesthesia. CONCLUSIONS: even if TDC is a common lesion of pediatric patients, anecdotical neonatal cases were described in the literature, all of them symptomatic. An accurate physical examination and ultrasound are essential diagnostic tools to distinguish TDC from other middle neck lesions, particularly ectopic thyroidal tissue. Sistrunk's procedure is the most effective surgical approach. When diagnosis is made in a newborn, we suggest postponing surgery, unless the baby requires general anesthesia for other surgical procedures, such as in our case.

Pneumatic pyloric dilatation for the treatment of gastric outlet obstruction in a child.

Acquired causes of gastric outlet obstruction (GOO) are rarely encountered in infancy, having an approximate incidence of 1 per 100,000 live births. Reports of short-term exposure to non-steroidal anti-inflammatory drugs having adverse events are few. We present the case of a previously healthy 3-year-old boy who developed severe chronic gastric outlet obstruction and antral stenosis after a short-term ingestion of liquid ibuprofen at a dosage not thought to be associated with unfavorable effects. Even though the optimal management of these cases remains to be determined, we report on a prompt and successful endoscopic treatment for this condition.

Testicular torsion during the COVID-19 pandemic: Results of a multicenter study in northern Italy.

INTRODUCTION: The literature reported an increased avoidance of the Emergency Department (ED) during COrona VIrus Disease 19 (COVID-19) pandemic, causing a subsequent increase of morbidity and mortality for acute conditions. Testicular torsion is a surgical emergency, which can lead to the loss of the affected testicle if a delayed treatment occurs. As testicular loss is time-related, outcome was hypothesized to be negatively affected by the pandemic. OBJECTIVE: The aim is to investigate whether presentation, treatment and outcomes of children with testicular torsion were delayed during COVID-19. STUDY DESIGN: Medical records of pediatric patients operated for testicular torsion of six Paediatric Surgical Units in Northern Italy between January 2019 and December 2020 were retrospectively reviewed. Patients were divided as for ones treated during (dC) or before the pandemic (pC). To reflect possible seasonality, related to lockdown restrictions, winter and summer calendar blocks were also analysed. For all cohorts, demographic data, pre-operative evaluation, operative notes and post-operative outcomes were reviewed. Primary outcomes were referral time, time from diagnosis to surgery and ischemic time, while secondary outcomes were orchiectomy and atrophy rates. Statistic was conducted as appropriate. RESULTS: A total of 188 patients with acute testicular torsion were included in the study period, 89 in the pre-COVID-19 (pC) period and 99 during COVID-19 (dC). Time from symptom onset to the access to the Emergency Department (T1) was not different among the two populations (pC: 5,5 h, dC: 6 h, p 0.374), and similarly time from diagnosis to surgery (pC: 2,5 h, dC: 2,5 h, p 0.970) and ischemic time (pC: 8,2 h, dC: 10 h, p 0.655). T1 was <6 h in 46/99 patients (46%) pC and 45/89 patients (51%) dC (p = 0.88, Fisher's exact test). Subgroup analysis accounting for different lockdown measures, confirm the absence of any difference. Orchiectomies rate was 23% (23/99) dC and 21% (19/89) pC (p = 0.861, Fisher's exact test) and rate of post-operative atrophy was 9% dC (7/76) and 14% pC (10/70), p = 0,44, Fisher's exact test. DISCUSSION: Despite worldwide pediatric ED accesses reduction, we reported that neither ischemic time nor the long-term outcomes in children with testicular torsion increased during the COVID-19 pandemic. In the available literature, few studies investigated the topic and are controversial on the results. Similarly to our findings, some studies found that timing and orchiectomy rates were not significantly different during the pandemic, while others reported a correlation to pandemic seasonality. Furthermore, in the recent pediatric literature it has been reported a delayed testicular torsion diagnosis due to shame in informing parents. Strengths of this study are the large numerosity, its multicentric design and a long study period. Its main limitation is being retrospective. CONCLUSIONS: We reported our large cohort from one of the most heavily COVID-19-affected regions, finding that referral, intra-hospital protocols and ischemic time in testicular torsion were not increased during to the pandemic, as well as orchiectomy rate and atrophy.

Focal nodular hyperplasia in pediatric patients with and without oncologic history.

The diagnosis of FNH is warranted by the possibility of avoiding unnecessary hepatic resections. The 18 patients of our series, 6 of whom were long-term survivors of malignant, non-hepatic tumors, underwent either a biopsy or a complete excision to obtain the diagnosis. The imaging characteristics could not be considered pathognomonic. The lesion remained stable after the biopsy in 8 patients; no complications were observed in other 10 patients who underwent resection of the mass. The outcome of all our patients with or without previous oncological disease was benign.

Edges-On-Dartos: An Easy Way to Improve Graft Performance in Staged Hypospadias Repair.

OBJECTIVES: To present a technical tip to be incorporated in the first stage of a 2-stage graft repair of proximal hypospadias associated with curvature, aiming at widening the graft bed and enhancing mobility of the lateral portions of the graft for subsequent urethroplasty. METHODS: After penile straightening, the dorsal dartos layer, carefully preserved attached to the dorsal penile skin used for penile coverage, is anchored to the lateral edges of the denuded corpora cavernosa with 3 to 4 interrupted 6-0 resorbable stiches on each side. The dartos creates a sort of hammock in-between the corpora, on which the central portion of the graft is quilted as in standard staged graft repair, and the skin margins laterally. Therefore, it widens the graft bed by 3-4 mm on each side. The lateral portions of the graft, laying on dartos, also remain supple for subsequent tabularization. RESULTS: Between 2017 and 2019, the technique was used in 16 cases (range 10-19 months). None of these patients required re-grafting because of severe longitudinal graft shrinkage. CONCLUSION: The described modification seems a simple tip to be incorporate in staged graft urethroplasty. Putative advantages include that a wider graft can compensate for some graft shrinkage occurring in-between stages; during the second stage, it can facilitate dissection and improve mobility of the lateral graft portions for tubularization, and make retrieval of a dartos flap for urethroplasty coverage easier. Prospective evaluation and comparative data are needed.

Management of Congenital Urethral Strictures In Infants. Case Series.

PURPOSE: Infra-vesical obstruction is uncommon in infants and generally due to urethral valves. Congenital urethral strictures (CUS), instead, defined as a concentric narrowing of the urethral lumen, are exceedingly rare in infants. MATERIALS AND METHODS: We reviewed our experience with 7 patients treated at our institution for CUS

Feeding Jejunostomy: Is It a Safe Route in Pediatric Patients? Single Institution Experience.

INTRODUCTION: Impossibility to place a gastrostomy and failed gastroesophageal reflux surgery with unsafe swallow are the main indications to Feeding Jejunostomy (FJ) in children. The aim of this study is to quantify the incidence of complications associated with FJ. MATERIALS AND METHODS: A retrospective review of patients who had surgically inserted FJ between January 2009 and August 2013 at our institution was conducted. Data were obtained from medical records, operative notes, and radiology database, focusing on complications. RESULTS: A total of 19 patients, average age 39.6 months (3-168 months), were treated during the study period. Indications to FJ were gastroesophageal reflux disease (GERD) associated with unsafe swallow in 12, esophageal atresia in 5, and foregut dysmotility in 2. Seventeen FJ were inserted via laparotomy and 2 were laparoscopically assisted. In all cases, a serosal tunnel on the antimesenteric border was fashioned. No intraoperative complications were recorded. Tube dislodgement/blockage occurred on an average of 0.48 times per month in 18 out of 19 patients. The average radiation dose received for tube reinsertion/manipulation was 3.316 mSv/year/patient (0-10.66). Major postoperative complications occurred in 7 out of 19. After an average follow-up of 21 months, two have abandoned the use of FJ due to poor tolerance and three have fully weaned off. Two patients died due to unrelated causes. CONCLUSION: FJ, as an alternative means for enteral feeding, may require multiple readmissions and exposure to radiological procedures. The high risk of severe complications should be considered when offering this procedure.

Instrumentation for minimally invasive surgery in pediatric urology.

The success of modern surgery is dependent on the availability of good equipment and instruments. This dependence increases along with the degree of sophistication of the surgery performed. Paediatric minimally invasive and endoscopic surgery are sophisticated techniques where imaging is obtained through a video-circuit. Endoscopic surgery has opened the field of virtual reality in surgery, and in minimally invasive surgery the actual operation is done through a limited number of small holes. Robot-assisted urologic surgery is an emerging and safe technology for many urologic paediatric operations, although further documentation, including long-term functional outcome, is deemed necessary before definite conclusions can be drawn regarding the superiority or not of robotic assistance compared to conventional laparoscopic approaches.

Concurrent fibroadenoma and intraductal papilloma - A recurring complex lesion in a premenarcheal girl.

Breast diseases are rare in childhood and adolescence, most lesions being fibroadenomas and papillomas. We report the case of an 11-year old girl with a complex breast lesion with hybrid features of fibroadenoma and intraductal papilloma with an early recurrence. Microscopically, the lesion was composed of dilated ducts showing intraluminal papillary projections with small to broad fibrovascular stalks. The typical leaf-like appearance of fibroadenoma was determined by the presence at the periphery of ducts compressed and distorted by the prominent stromal component. Despite its florid epithelial hyperplasia and mild cytological atypia (more evident in the relapse), immunohistochemical staining for p63 and smooth muscle actin highlighted a continuum outer myoepithelial layer, confirming the non-invasive appearance of the lesion. Two pathogenetic links have been hypothesized: one is based on the morphological continuum between these two entities, which may represent different evolutive stages in the same lesion; the other is based on epithelial/mesenchymal interactions. The possible malignant transformation of such complex lesion is also discussed, along with its differential diagnoses. The relevance of this case lies in its rarity, as well as in the therapeutic strategies related to its biological potential and to the necessity of a conservative treatment, due to the young age of the patient.

Sparing-lung surgery for the treatment of congenital lung malformations.

PURPOSE: Congenital lung malformations (CLM) are traditionally treated by pulmonary lobectomy. The foremost indication for surgery is that these lesions predispose to respiratory tract infections and to malignancy. Owing to the improvement of prenatal diagnosis, most patients are operated in a timely manner and prophylactically. In this context, lung-sparing surgery (LS) has gained interest as a lung preservation strategy, especially for asymptomatic patients. In the present study, we evaluated both thoracoscopic and open lung-preserving resections as an alternative to lobectomy for CLM resection. METHODS: We retrospectively reviewed all patients who underwent lung-sparing resection (segmentectomy and atypical resection) for CLM from 2001 to 2010. Data were collected regarding preoperative diagnostic workup, type of intervention, and follow up. RESULTS: Fifty-four patients received LS for CLM during the study period. Twenty-six were approached thoracoscopically, with 18 cases requiring open conversion for a complete resection. There were six postoperative complications: three asymptomatic pneumothoraces that resolved without intervention, one tension pneumothorax that required replacement of a drainage catheter, and three instances of intra-operative bleeding requiring blood transfusion. Mean duration of follow-up was 65.2 months. Two patients experienced pneumonia during the follow-up period. A third patient had a cystic lung lesion on postoperative computed tomography (CT) which required a second-look surgery. CONCLUSIONS: LS for CLM is a safe and effective means of lung parenchymal preservation in pediatric patients. Complication rates are comparable to that of traditional lobectomy. In our experience, this type of lung surgery does not carry a higher risk of residual disease and recurrence if accurately planned in selected patients, i.e., those with small asymptomatic lesions. The complication rate is acceptable and apparently not affected by preoperative symptoms. The thoracoscopic approach is recommended, although open conversion should be advocated to avoid too long operative times.

Bilateral hydrosalpinx with asynchronous tubal torsion: an exceptional finding in a premenarcheal girl.

Bilateral hydrosalpinx with asynchronous tubal torsion is an extraordinary event in young girls. This report describes the problems associated with misdiagnosis, therapeutic approach, and the risk of suboptimal treatment of this rare clinical entity in a 13-year-old girl.

Giant fibroadenoma of the breast in adolescents: report of 2 cases.

Giant fibroadenoma (GF) is an uncommon variant of fibroadenomas that represent the most frequent breast lesion in adolescents and young women. The authors present 2 cases of GF of the breast in girls aged 12 and 14 years, and the respective diagnostic workup and conservative surgical treatment. Giant fibroadenomas are benign tumors, but their rapid growth and large size together with their rarity may determine difficulties in the clinical approach. Moreover, GF must be excised in all cases to exclude a phyllodes tumor and to prevent later deformity.

Ciliated hepatic foregut cyst: from antenatal diagnosis to surgery.

Ciliated hepatic foregut cyst is the only ciliated cystic lesion known to occur in the liver. It is an extremely rare, benign and solitary cyst that probably arises from remnants of the embryonic foregut in the liver. We report a 16-month-old girl who underwent surgical excision of a hepatic cyst discovered during antenatal ultrasonography. Surgical exploration and excision were performed because of the uncertain aetiology of the cyst and because on postnatal follow-up US the size of the mass had increased causing extrinsic biliary obstruction. Pathology revealed a ciliated hepatic foregut cyst. This is the fourth child affected by this lesion reported in the literature, the second undergoing surgical excision, and the second with antenatal diagnosis.

Right congenital diaphragmatic hernia: an 18-year experience.

BACKGROUND: Prenatal diagnosis and outcome of right congenital diaphragmatic hernia (RCDH) are far less well known than the more common left CDH (LCDH). In addition, onset of RCDH beyond the neonatal period with a spectrum of atypical symptoms is not unusual. A retrospective analysis of RCDH treated at a single center over 18 years has been reviewed with regard to outcome after the introduction of a new treatment protocol for CDH. METHODS: All charts of patients with CDH between 1987 and 2004 were reviewed. Twenty-nine patients with RCDH were identified. The patients were divided into 2 historical groups: group 1, from 1987 to 1998 (16 patients), and group 2, from 1999 to 2004 (13 patients). From 1999, at the Department of Pediatric Surgery of Padua, the management of a baby born with CDH has been standardized and includes planned delivery at term, high-frequency oscillatory ventilation since birth, inhaled nitric oxide if required, extracorporeal membrane oxygenation as a "last resort," and delayed repair once the infant is hemodynamically stable. Patients with either prenatal diagnosis of RCDH or early onset of symptoms (<6 hours of life) were considered "high risk," and those with late onset (>6 hours) were considered "low risk." RESULTS: Of 29 patients, prenatal diagnosis was available in 8 (27.5%) and major associated malformations in 8 patients (27.5%). Eight (50%) of 16 cases from group 1 and 9 (69.2%) of 13 cases from group 2 were high-risk patients. There was a trend in favor of a higher survival among high-risk patients from group 2 (25% vs 44%), although this was not statistically significant. As expected, all low-risk patients survived (P = .0001). Plain thorax x-ray was diagnostic in 23 (82.1%) cases, initially normal in 3, not performed in 1, and misinterpreted as right lower lobe pneumonia in 2. At operation, the prosthetic patch was required in 2 (9%) of 22 cases and the peritoneal sac was found in 4 (13.7%). CONCLUSIONS: (1) The rate of prenatal diagnosis of RCDH was low and remained stable throughout the examined period. (2) The introduction of a treatment protocol, using high-frequency oscillatory ventilation since birth, improved the survival of high-risk patients with RCDH, although the data did not reach statistical significance. (3) The majority (75%) of low-risk patients presented beyond the first week of life with a variety of aspecific gastrointestinal or respiratory symptoms that accounted for initial misdiagnosis. (4) Even in these cases, the outcome was excellent.

Neonatal intrapericardial teratoma: a challenge for the pediatric surgeon.

Congenital intrapericardial teratoma can present in the fetal and neonatal period, but prenatal diagnosis is difficult. Its clinical course, similar to that of an anterior mediastinal mass, may be fatal if the tumor is not promptly excised. We report the case of a fetus with a large anterior mediastinal mass associated with hydramnios, pleural effusion, and ascites. Perinatal surgical removal is the only lifesaving therapy; any conservative approach in these neonates should be avoided even if critically symptomatic.
