RESUMEN
Background: Few studies have evaluated the efficacy of short-term medical missions. This study was aimed to evaluate complication rates and determine the effects of protocol changes in a pediatric inguinal hernia campaign in Equatorial Guinea and analyze post-operative follow-up capacity. Methods: In this prospective observational cohort study, we evaluated two patient cohorts (group A, 2017-2018; group B, 2019) treated during campaigns in Equatorial Guinea for congenital inguinal pathology (hernia, hydrocele, and cryptorchidism). Patients aged < 18 years treated in referral campaigns were included. Complications occurring up to 6 months post-operatively were evaluated. Two stages were defined: Stage 1, wherein, complication rate in group A was compared to that in a control group from a tertiary hospital in Spain (with a case-control ratio of 1:2, paired according to age, sex and diagnosis); stage 2, wherein, complication rates between groups A and B were compared. Group B received a single dose of prophylactic amoxicillin-clavulanic acid. Follow-up capacity was assessed through follow-up appointments. Results: In stage 1, complication and surgical site infection (SSI) rates were 21.3% and 7.4% in group A (n = 94), and 5.8% (p < 0.001) and 0.5% (p = 0.012) in the control group, respectively. Group A had 20.2% loss-to-follow-up. In group B (n = 62), 6-month postoperative follow-up could not be assessed owing to restrictions due to the COVID-19 pandemic, so only early complications were considered in stage 2, were complication and surgical site infection rates were 18.1% and 7.4% in group A and 11.3% (p = 0.350) and 1.6% (p = 0.150) in group B. Conclusion: Our results showed higher than expected complication rates. Pre-operative prophylactic antibiotic could not show to reduce SSI. Further studies are needed to reduce complication rates in these campaigns. Patient loss-to-follow-up ratio warrants considering new strategies.
RESUMEN
BACKGROUND: The integration of 3D printing technology in hospitals is evolving toward production models such as point-of-care manufacturing. This study aims to present the results of the integration of 3D printing technology in a manufacturing university hospital. METHODS: Observational, descriptive, retrospective, and monocentric study of 907 instances of 3D printing from November 2015 to March 2020. Variables such as product type, utility, time, or manufacturing materials were analyzed. RESULTS: Orthopedic Surgery and Traumatology, Oral and Maxillofacial Surgery, and Gynecology and Obstetrics are the medical specialties that have manufactured the largest number of processes. Working and printing time, as well as the amount of printing material, is different for different types of products and input data. The most common printing material was polylactic acid, although biocompatible resin was introduced to produce surgical guides. In addition, the hospital has worked on the co-design of custom-made implants with manufacturing companies and has also participated in tissue bio-printing projects. CONCLUSIONS: The integration of 3D printing in a university hospital allows identifying the conceptual evolution to "point-of-care manufacturing."
RESUMEN
La ingesta accidental de más de un imán puede producir complicaciones graves. Los protocolos actuales recomiendan la extracción endoscópica de ser posible. El objetivo de este trabajo es presentar un caso clínico de una ingesta de dos imanes y la técnica endoscópica de extracción. Niño de 11 años que acudió a Urgencias tras la ingesta de dos imanes, asintomático. En la radiografía de abdomen, se identificaron dos cuerpos extraños radiopacos, aparentemente unidos, en la cámara gástrica. Se realizó una endoscopía bajo anestesia general en quirófano. Para facilitar la extracción, se colocó, encima de la pared abdominal, a nivel gástrico, un imán de neodimio. En la endoscopía, se observaron dos pequeños imanes localizados y fijados en la cara anterior del estómago. Una vez localizados, se retiró el imán externo y se procedió a su extracción con cesta
The ingestion of more than one magnet can cause multiple complications. Current protocols recommend endoscopic extraction if possible. We report a patient who swallowed two magnets and the endoscopic extraction technique. An 11-yearold boy presented at the Emergency Room after ingesting two small magnets, being asymptomatic. In the abdominal x-ray two radiopaque bodies were identified at the gastric chamber, apparently together. A gastroscopy was done in the operating room under general anaesthesia. To enable the extraction, a neodymium magnet was placed externally at the abdominal wall. In the endoscopic image, the two magnets were fixed to the anterior gastric wall. Once located, the neodymium magnet was removed and the two magnets were retrieved with an endoscopic basket.

AIM: In the last years it has spread minimally invasive therapeutic for the treatment of pyeloureteral junction obstruction in children. Some of them have got poor outcomes in 4-year-old minor children. We show our experience in the retrograde dilatation with balloon of high pressure in infants. METHODS: It's a retrospective study of 16 infants treated in our hospital. The average follow-up after the intervention is 27.4 +/- 10.0 months. The diagnostic protocol included abdominal ultrasound, cystogram and diuretic renography. The treatment was realized by endourology retrograde balloon dilatation under fluoroscopy. The balloons were in all the cases semicompliant, with a profile of 5 mm, 6 mm 6 7 mm. After the expansion there was placed stents type double J with profile and length depending on the weight of the patient. To obtain the results, we do ultrasound scans and diuretic renography at least 1 year after the intervention. RESULTS: The mean duration of the intervention was 36.4 +/- 15.5 minutes. During the intervention, in 2 patients the placement of the stent was not possible. The time of revenue was 48 hours in all the patients except in 1 of them. The analgesic needs were exclusively non steroid antiinflammatorys. The double J stent was withdrawn with cystoscopy. In 3 patients there were postoperatory complications: a migration of the stent, a urinary infection and an urinoma. In 1 patient with worsening of hydronephrosis was needed of pyeloplasty. In the controls the disappearance of the hydronephrosis was observed in all the cases, eliminating likewise the expansion of the renal calyces. The diuretic renography improved in all babies, being the boss of the curve normal in 14 cases and semi obstructively in 2. The mean time of elimination was 9.8 +/- 2.8 minutes. CONCLUSIONS: We think that the balloon dilatation of pyeloureteral junction obstruction is a minimally aggressive technique that is possible to realize in infants with good results and scanty complications.
