Introduction: Lung reexpansion is a rare complication, generally less than 1%, that can occur after rapid drainage of a pneumothorax or pleural effusion. Its mortality can reach 20%.Clinical case: A 22-year-old female patient reported experiencing dizziness, weakness, vomiting containing food, presence of blood clots and bloody-looking stools, which is why she was taken to the hospital to the emergency department, and underwent surgery for upper digestive bleeding. In its evolution, it presents a picture of acute unilateral lung injury secondary to lung reexpansion when draining a pleural effusion. Medical and ventilatory treatment is imposed and the patient evolves favorably.Conclusions: Lung injury due to lung re-expansion is a rare entity; clinical suspicion is essential to act diligently and thus avoid complications. Good ventilatory management of Respiratory Distress Syndrome is essential, emphasizing protective mechanical ventilation and the appropriate use of PEEP

Introduction. Down syndrome (DS) is the most common chromosomal alteration. Mortality during the first year of life in this group is high. Newborns with this condition have a higher risk of developing cholestasis. Infants with DS can develop cysts. of common bile duct secondary to cholestasis, in pediatric patients common bile duct cysts are a rare pathology. Clinical Case. 9-month-old infant with a history of DS. On general physical examination, the skin and mucous membranes were generally moist and jaundiced, isochoric and photoreactive pupils, icteric sclerae, with hepatomegaly 3 cm below the costal margin and splenomegaly 2 cm from the rib cage, abdominal perimeter 49 cm. Laboratory and imaging studies, including cholangioresonance, are performed to confirm the diagnosis of Todani IVa choledochal cyst.Conclusions. In patients with Down syndrome who present a clinical picture of vomiting, abdominal pain and jaundice, the diagnosis of choledochal cyst should be considered. Cholangioresonance is the study that confirms the presence of a choledochal cyst. Our clinical case was evaluated by the surgery service and a surgical procedure was scheduled for resection of the cyst

Introduction: Omental cysts are rare intra-abdominal lesions, with a frequency of 1:250,000, which often present asymptomatically. However, they can cause abdominal distension, or even surgical abdominal symptoms. Case report: A 3-year-old female patient presents with a clinical picture of 2 years of evolution, reporting progressive abdominal distention since she was one year old and abdominal pain for 2 weeks. Physical findings show an abdomen with great abdominal distention, tense and painful on superficial and deep palpation. A contrast-enhanced CT scan of the abdomen and pelvis revealed abdominopelvic cystic lesions. Exploratory laparotomy revealed a giant multilocular cystic mass dependent on the greater omentum. The pathological report revealed a giant omentum cyst. A successful surgical resection of the cystic lesions was performed and a favorable post-surgical evolution was performed. Conclusions: Omentum cysts are rare in paediatrics. Diagnosis is based on imaging studies and is confirmed during surgery. Surgical treatment is effective and with few complications

Historically, measles has been an infectious disease responsible for significant morbidity and mortality worldwide. Global vaccination efforts have had a transformative impact, with measles immunization estimated to have prevented more than 60 million deaths globally between 2000 and 2023. Despite these successes, the global goal of measles elimination by 2030, outlined in the Measles and Rubella Strategic Framework 2021-2030, is now under considerable threat due to the recent re-emergence of the disease. Addressing the measles crisis is not only about containing this specific virus, but also about strengthening the fundamental resilience of public health systems worldwide to prepare for and mitigate a broader spectrum of infectious disease threats. This narrative review article aims to provide a comprehensive analysis of the global re-emergence of measles. Clinical and epidemiological trends will be detailed, key factors contributing to this resurgence will be identified, and public health implications will be examined. An analysis of the situation in Bolivia will be included, offering localized perspectives on the challenges and responses. Finally, the article will conclude with strategic recommendations for public health interventions and future preparedness.

Introduction: Mesenteric polycystic lymphangiomas are rare cystic tumors, with a 5% incidence compared to their incidence in the neck and axillae (95%), seen more frequently in pediatric patients, rare in patients over 20 years of age.Clinical case: A 3-year-old male patient presents with a clinical picture of one day of evolution, reporting abdominal pain of moderate intensity, temperature rises and vomiting. Physical findings show abdominal distension, with ultrasound showing a polycystic lesion, and contrast-enhanced tomography corroborating a lobulated multi-separated cystic formation. Exploratory laparotomy revealed a polycystic tumor at the level of the ileum mesentery. The anatomopathological study describes a polycystic mesenteric lesion. Exeresis is performed and the postoperative evolution is satisfactory.Conclusions: Polycystic mesenteric lymphangiomatosis is a rare tumor that mainly affects the mesentery of the small intestine and/or colon. In pediatric age, this condition should be considered as a differential diagnosis of acute abdomen. Conventional or laparoscopic surgery is the cornerstone of treatment

Congenital malformations constitute anomalies of structure and/or function of prenatal origin, which are often asymptomatic or cause few symptoms, but currently have a high incidence. With the aim of showing the findings detected in the imaging studies carried out, the case of a young adult with repeated mild urinary sepsis is presented, who was diagnosed with multiple and bilateral renoureteral malformations in the infertility consultation. The majority of congenital renoureteral malformations imply serious biopsychosocial problems for the patient, with the consequent impact on the psychological sphere and the social life of family members when diagnosed in the prenatal stage, so they inevitably constitute a health problem, since they contribute to fetal and infant mortality or increased morbidity in any age group. For this reason, early diagnosis is essential to guarantee appropriate behavior and quality of life.

Introduction. Septic arthritis in the pediatric age group is a medical emergency with serious consequences if not treated early. Early diagnosis is essential to initiate appropriate treatment and prevent permanent joint damage. Ultrasound has emerged as an essential tool for the early and accurate detection of septic arthritis, allowing for a rapid and detailed evaluation of the affected joint, especially in cases where clinical findings are subtle.Clinical Case. A 1-month-old male infant was brought by his mother to the emergency service of our hospital due to irritability and crying when changing his diaper, significant increase in the volume of the right thigh, and pain during movement. An initial ultrasound was performed, which reported signs of superficial cellulitis, and a second ultrasound was performed, which revealed thickening of the synovium, a fluid collection in the joint capsule with echoes inside it, which concluded with the diagnosis of septic arthritis of the right hip.Discussion. Ultrasound not only allowed the identification of joint effusion and synovial thickening, but was also crucial in differentiating between superficial infection (cellulitis) and deeper septic arthritis.Conclusions. The importance of our clinical case lies in the use of ultrasound as a diagnostic method to detect joint involvement early. In combination with the clinical method and microbiological studies, it becomes an important component of the diagnostic approach and timely management of septic arthritis, thus reducing associated complications.

Case reports: Case 1 is a male patient who presented with left lumbar pain and wanders to the emergency department. Case 2: a female patient is brought to the emergency department in hypovolemic shock. In both cases, it was decided to perform urgent surgical treatment to correct the hemorrhage due to the progressive deterioration of hemodynamics, the subsequent evolution was favorable.Relevance: Wünderlich syndrome is characterized by retropritoneal hemorrhage localized at the renal or perirenal level, which occurs sudden onset. Implications: The available evidence on this pathology is scarce because it is a little suspected medical emergency.Conclusion: Wünderlich syndrome presents relatively frequently in emergency departments and represents a diagnostic-therapeutic challenge.
