Sequential teratoma in pediatric patients: causation or coincidence?

We describe the unusual case of a female patient with a history of two mature teratomas non-correlated in terms of location and occurrence. A 12-year-old girl presented at our consultation as a result of a growing tumor in the hypogastric region, with no further clinical signs. She had undergone surgery neonatally due to a mature cystic sacrococcygeal teratoma, which was fully removed.

Matrix Cauterization With Silver Nitrate in the Treatment of Ingrown Toenails in Children: Pilot Study.

Background: Although partial onychectomy with chemical matricectomy has been described asthe treatment of choice, there is sparse evidence in the literature regarding the use of silvernitrate for matricectomy. Our aim is to describe the effectiveness of silver nitrate for matrixcauterization after partial onychectomy.

Methods: A prospective observational study was performed on patients with ingrown toenailsstage 2-3 who underwent partial onychectomy with silver nitrate chemical matricectomy during 2018-2019 in our institution.

Ultrasound-Guided Percutaneous Cryoanalgesia for Pectus Excavatum: When Should It be Applied?

Introduction:  The addition of ultrasound-guided percutaneous cryoanalgesia (PCr) for pain management after pectus excavatum (PE) surgery offers a new and advantageous approach. Our aim is to describe our experience with PCr applied on the same day, 24 hours, and 48 hours prior to PE surgery.

Material And Methods:  Prospective pilot study in patients undergoing ultrasound-guided PCr (2019-2022) was divided into three groups: PCr on the same day of surgery (PCrSD), PCr 24 hours before (PCr24), and PCr 48 hours before (PCr48).

Perineal groove: an old, little known entity.

Introduction: Perineal groove is an infrequent midline malformation. It is a humid, mucosal, non-keratinized groove located at the perineal midline, extending from the vulvar fourchette to the anterior anal border. It is rare and usually asymptomatic, and it heals spontaneously in most cases.

Diffuse hepatocutaneous hemangiomatosis: an unusual presentation.

Introduction: Infantile hemangiomas with multi-organ involvement are rare, and presentation in the form of uncontrollable bleeding is exceptional.

Clinical Case: 4-day-old newborn with multiple hepatocutaneous hemangiomas and a purplish vascular lesion in the third finger of the right hand. In the third week of life, the lesion became ulcerated and caused uncontrollable bleeding.

Postoperative Pneumoperitoneum in Pediatric Patients: Residual Air or Surgical Complication? A Prospective Study.

Residual postoperative pneumoperitoneum (RPP) can be confused with postoperative complications. Our aim was to study RPP characteristics in pediatric patients. Prospective study in children with noncomplicated appendicitis, from July to December 2019, divided into open appendectomy (OA) or laparoscopic appendectomy (LA).

Percutaneous Cryoanalgesia: A New Strategy for Pain Management in Pectus Excavatum Surgery.

Introduction:  In recent years, pain protocols for pectus excavatum (PE) have incorporated cryoanalgesia through thoracoscopic approach. Since 2019, ultrasound-guided percutaneous cryoanalgesia (PCr) has been applied at our institution, either on the same day as the Nuss procedure or 48 hours before surgery. We carried out a preliminary retrospective review of patients with PE in whom PCr prior to surgery was performed at our institution between 2019 and 2021.

Healthcare staff as promoters of parental presence at anesthetic induction: Net Promoter Score survey.

Background: Surgical intervention is usually a traumatic event that causes stress and anxiety in the pediatric patient and the family environment. To reduce the harmful effects of presurgical anxiety, parental presence during induction of anesthesia (PPIA) is one of the more notable interventions used in medical centers. However, data on this measure are difficult to evaluate and often face resistance from healthcare staff.

Impact of SARS-CoV-2 pandemic on emergency department activity at the pediatric surgery unit of a third-level hospital.

Introduction: As a result of the emergence of the SARS-CoV-2 respiratory virus in Wuhan in December 2019, the Spanish Government declared the state of emergency with restrictions such as stay-at-home lockdown. The objective of this study was to analyze emergency activity at a referral pediatric surgery unit in its territory and determine whether surgical pathologies had decreased or not.

Methods: A retrospective study of pediatric patients presenting at the emergency department and referred to the pediatric surgery unit from March 14, 2020 to April 20, 2020 was carried out.

Does time to antibiotic initiation and surgery have an impact on acute appendicitis results?

Objective: Time to treatment initiation is a key element to be considered in infectious pathologies such as acute appendicitis (AA). There are few articles in the literature analyzing the relationship between early pre-surgical antibiotic treatment initiation and complication occurrence in AA. Our objective is to analyze such influence and the effects of late treatment initiation.

Influence of overweight and obesity on acute appendicitis in children. A cohort study.

Introduction: Overweight and obesity are risk factors for the development of postsurgical complications in acute appendicitis in adults. However, there are few studies that evaluate their effects in pediatric patients. We aim to analyze their influence on the postoperative course of acute appendicitis in children.

Neutropthil-to-Lymphocyte Ratio as a Predictor of Postsurgical Intraabdominal Abscess in Children Operated for Acute Appendicitis.

Postoperative intra-abdominal abscess (PIAA) is a frequent and severe complication of acute appendicitis (AA) with peritonitis. The neutrophil-to-lymphocyte ratio (NLR) is an inflammatory marker that has been related to the development of peritonitis; however, its diagnostic role in predicting PIAA has not been evaluated. This is the first study that analyzes the usefulness of NLR as a predictor of PIAA in children operated for AA.

[Neutrophil-to-lymphocyte ratio as a predictor of peritonitis in acute appendicitis in children].

Aim Of The Study: The neutrophil-to-lymphocyte ratio (NLR) has been postulated as an inflammatory marker in several abdominal pathologies such as acute appendicitis (AA). However, there are few studies that determine its association with the degree of severity of AA. This is the first study that analyzes the usefulness of NLR as a predictor of peritonitis in children with AA.

Global exchange and accumulation of non-native plants.

All around the globe, humans have greatly altered the abiotic and biotic environment with ever-increasing speed. One defining feature of the Anthropocene epoch is the erosion of biogeographical barriers by human-mediated dispersal of species into new regions, where they can naturalize and cause ecological, economic and social damage. So far, no comprehensive analysis of the global accumulation and exchange of alien plant species between continents has been performed, primarily because of a lack of data.
