Do FETO CDH survivors need the same follow-up program as non-FETO patients?

Congenital diaphragmatic hernia (CDH) survivors are at risk of developing significant chronic health conditions and disabilities. The main purpose of this study was to compare the outcomes of CDH infants at 2 years of age (2y) according to whether the infants had undergone fetoscopic tracheal occlusion (FETO) during the prenatal period and characterize the relationship between morbidity at 2y and perinatal characteristics. Retrospective cohort single center study. Eleven years of clinical follow-up data (from 2006 to 2017) were collected. Prenatal and neonatal factors as well as growth, respiratory, and neurological evaluations at 2y were analyzed. One hundred and fourteen CDH survivors were evaluated. Failure to thrive (FTT) was present in 24.6% of patients, gastroesophageal reflux disease (GERD) in 22.8%, 28.9% developed respiratory problems, and 22% had neurodevelopment disabilities. Prematurity and birth weight < 2500 g were related to FTT and respiratory morbidity. Time to reach full enteral nutrition and prenatal severity markers seemed to influence all outcomes, but FETO therapy itself only had an effect on respiratory morbidity. Some variables related to postnatal severity (ECMO, patch closure, days on mechanic ventilation, and vasodilator treatment) were associated with almost all outcomes.  Conclusion: CDH patients have specific morbidities at 2y, most of them related to lung hypoplasia severity. Only respiratory problems were related to FETO therapy itself. The implementation of a specific multidisciplinary follow-up program for CDH patients is essential to provide them the best standard of care, but, more severe patients, regardless of whether they received prenatal therapy, need a more intensive follow-up. What is Known: • Antenatal fetoscopic endoluminal tracheal occlusion (FETO) increases survival in more severe congenital diaphragmatic hernia patients. • Congenital diaphragmatic hernia survivors are at risk of developing significant chronic health conditions and disabilities. Very limited data are available about the follow-up in patients with congenital diaphragmatic hernia and FETO therapy. What is New: • CDH patients have specific morbidities at 2 years of age, most of them related to lung hypoplasia severity. • FETO patients present more respiratory problems at 2 years of age but they don't have an increased incidence of other morbidities. More severe patients, regardless of whether they received prenatal therapy, need a more intensive follow-up.

Percutaneous or Endoscopic Treatment of Peripheral Bile Duct Leaks: Initial Experience with an Innovative Approach of Microcatheter-Delivered Argon Plasma Coagulation.

PURPOSE: Biliary ductal injuries are challenging to treat, and often lead to severe morbidity and mortality. The first-line approach involves endoscopic retrograde cholangiopancreatography with sphincterotomy and, in case of refractory leakage, long-lasting percutaneous transhepatic biliary drainage, endoscopic or percutaneous injection of sclerosing agents and/or coiling can be used. We describe a treatment procedure using microcatheter-mediated percutaneous or endoscopic argon plasma coagulation (APC). MATERIALS AND METHODS: Three patients (7-year-old male, 14-year-old male, 81-year-old female) with refractory postsurgical and/or post-traumatic bile leaks underwent percutaneous (n = 2) or endoscopic (n = 1) APC through a detachable microcatheter. RESULTS: The procedure was technically feasible in all patients. Postoperative imaging showed complete occlusion of biliary leakage. The technique was uneventful intraoperatively with no adverse events occurring during recovery or follow-up. CONCLUSION: Our initial experience demonstrates that refractory bile duct leaks may be successfully treated with microcatheter-mediated APC endoscopically or percutaneously. Further research is needed to confirm the safety, efficacy, and clinical indications for this innovative technique.

Prenatal diagnosis of Kagami-Ogata syndrome.

Kagami-Ogata syndrome (KOS14) is a rare congenital disorder associated with defective genomic imprinting of the chromosome 14q32 domain. Typical features include polyhydramnios, small and bell-shaped thorax, coat-hanger ribs, dysmorphic facial features, abdominal wall defects, placentomegaly, severe postnatal respiratory distress and intellectual disability. To the best of our knowledge, this may be the first case where ultrasound findings such as: severe polyhydramnios, a small bell-shaped thorax, a protuberant abdomen and characteristic dysmorphic face prompted directed family interrogation finally leading to the prenatal diagnosis of KOS14.

Endoscopic stenting for gastroduodenal outlet obstruction of a malignant origin, real life experience in a single center

AIM: to evaluate the safety and effectiveness of self-expandable metal stent placement for malignant gastric outlet obstruction (GOO). METHODS: a retrospective, analytic cohort study at a single, tertiary-care center. RESULTS: thirty-six patients that underwent stent placement for GOO of malignant origin were identified during the study period. Technical success was achieved in 36 (100 %) patients and clinical success was achieved in 31 patients (86.1 %). Before the procedure, 17 (54.8 %) patients had a gastric outlet obstruction score (GOOSS) of 0, which is a complete inability of oral intake. Twenty-three patients were alive 30 days after the procedure, two (8.6 %) patients had a GOOSS of 1, ten (43.3 %) had a GOOSS of 2 and eleven (47.9 %) had a GOOSS of 3. Abdominal pain was present in all 31 patients before the procedure and only seven (22.6 %) patients continued with abdominal pain 24 hours after the procedure. During follow-up, ten (30.3 %) patients developed complications related to the stents and none of them was fatal. Additional therapy due to partial occlusion of the stent was necessary in three patients. The stents functional duration had a median of 72 days (IQR 25-75 15-105 days) and was closely related to overall survival. CONCLUSION: palliative stenting for gastroduodenal obstruction is a safe, feasible and effective therapy to treat patients with malignant gastric outlet obstruction

The impact of droughts and climate change on sinkhole occurrence. A case study from the evaporite karst of the Fluvia Valley, NE Spain.

This work introduces the concept that sinkhole frequency in some karst settings increases during drought periods. This conception is tested in a sector of the Fluvia River valley in NE Spain, where subsidence phenomena is related to the karstification of folded Eocene evaporite formations. In the discharge areas, the evaporites behave as confined aquifers affected by hypogene karstification caused by aggressive artesian flows coming form an underlying carbonate aquifer. A sinkhole inventory with chronological data has been constructed, revealing temporal clusters. Those clusters show a good correlation with drought periods, as revealed by precipitation, river discharge and piezometric data. This temporal association is particularly obvious for the last and current drought starting in 1998, which is the most intense of the record period (1940-present). Climatic projections based on recent studies foresee an intensification of the droughts in this sector of NE Spain, which could be accompanied by the enhancement of the sinkhole hazard and the associated risks.

Nitrate pollution of groundwater; all right , but nothing else?

Contamination from agricultural sources and, in particular, nitrate pollution, is one of the main concerns in groundwater management. However, this type of pollution entails the entrance of other substances into the aquifer, as well as it may promote other processes. In this study, we deal with hydrochemical and isotopic analysis of groundwater samples from four distinct zones in Catalonia (NE Spain), which include 5 different aquifer types, to investigate the influence of fertilization on the overall hydrochemical composition of groundwater. Results indicate that intense fertilizer application, causing high nitrate pollution in aquifers, also homogenize the contents of the major dissolved ions (i.e.; Cl(-), SO4(2-), Ca(2+), Na(+), K(+), and Mg(2+)). Thus, when groundwater in igneous and sedimentary aquifers is compared, significant differences are observed under natural conditions for Cl(-), Na(+) and Ca(2+) (with p-values ranging from <0.001 to 0.038), and when high nitrate concentrations occur, these differences are reduced (most p-values ranged between 0.054 and 0.978). Moreover, positive linear relationships between nitrate and some ions are found indicating the magnitude of the fertilization impact on groundwater hydrochemistry (with R(2) values of 0.490, 0.609 and 0.470, for SO4(2-), Ca(2+) and Cl(-), respectively). Nevertheless, the increasing concentration of specific ions is not only attributed to agricultural pollution, but to their enhancing effect upon the biogeochemical processes that control water-rock interactions. Such results raise awareness that these processes should be evaluated in advance in order to assess an adequate groundwater resources management.
