Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Summary
Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally.
Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies
have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of
the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income
countries globally, and identified factors associated with mortality.
Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to
hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis,
exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a
minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical
status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary
intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause,
in-hospital mortality for all conditions combined and each condition individually, stratified by country income status.
We did a complete case analysis.
Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital
diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal
malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome
countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male.
Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3).
Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income
countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups).
Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome
countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries;
p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients
combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11],
p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20
[1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention
(ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety
checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed
(ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of
parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65
[0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality.
Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome,
middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will
be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger
than 5 years by 2030

Lesiones subcutáneas dolorosas en paciente con melanoma metastásico: un caso de paniculitis linfocĂtica asociado a vemurafenib
Vemurafenib ha probado ser una herramienta Ăştil en el tratamiento de melanoma metastásico con mutaciĂłn BRAF-V600E. Los efectos adversos incluyen artralgias, fatiga y toxicidad cutánea, siendo infrecuente la paniculitis. Presentamos el caso de una paciente de 43 años con melanoma metastásico que desarrolla lesiones subcutáneas dolorosas en miembros inferiores y superiores, asociadas a clĂnica sistĂ©mica despuĂ©s de 2 semanas de inicio de tratamiento con Vemurafenib + Cobimetinib. La histologĂa demostrĂł paniculitis linfocitaria septal y lobulillar. La paciente tuvo mala tolerancia al tratamiento anti diana a dosis plenas, requiriendo su ajuste, generando una corticodependencia para controlar sintomatologĂa, y que finalmente obligĂł a la descontinuaciĂłn de la terapia dirigida contra melanoma. A la fecha, se han descrito 29 casos en la literatura de paniculitis asociada a vemurafenib, siendo la mayorĂa paniculitis neutrofĂlicas con adecuado control de sintomatologĂa asociando antiinflamatorios no esteroidales y/o corticoides orales sin requerir en su mayorĂa modificaciĂłn de la terapia contra melanoma; sin embargo hay que tener presente que pueden haber casos con mala evoluciĂłn que obligan a la reducciĂłn de dosis de vemurafenib y descontinuar el tratamiento, como ha ocurrido en nuestro reporte.Vemurafenib has proven to be a useful tool in the treatment of metastatic melanoma with BRAF-V600E mutation. Adverse effects include arthralgia, fatigue, and skin toxicity; panniculitis is a rare complication. We present the case of a 43-year-old patient with metastatic melanoma who developed painful subcutaneous nodules of the lower and upper limbs and associated systemic clinical symptoms after 2 weeks of treatment with vemurafenib plus cobimetinib. Histology showed a septal and lobular lymphocytic panniculitis.The patient had poor tolerance of the full-dose treatment, requiring its adjustment. Systemic corticosteroids were required to control symptomatology, which finally forced the discontinuation of the medication.To date, 29 cases have been described in the literature of panniculitis associated with vemurafenib. Most of these have been neutrophilic panniculitis, but adequate control of symptoms is usually achieved with nonsteroidal anti-inflammatory drugs and/or oral corticosteroids without requiring modification of melanoma therapy. However, it must be borne in mind that there may be cases that force the reduction and discontinuation ofvemurafenib treatment. We believe that this histological variant of lymphocytic panniculitis and its poor response to decrease in vemurafenib makes this case unusual and instructive

El rojo es un problema: Reacciones cutáneas a pigmento rojo de tatuajes
La práctica de tatuajes tienen más de 8000 años de antigüedad, existiendo un incremento continuo en la sociedad occidental en las últimos 3 décadas La introducción de una sustancia exógena en la pielpuede provocar una respuesta inmunológica en su contra, estando descritas reacciones cutáneas por hipersensibilidad a una variedad de pigmentos, las que se limitan al área de un determinado color,atribuyéndose a los materiales inyectados. El color más reportado en la literatura es el rojo, que tradicionalmente se confeccionaban a base dederivados del mercurio (cinabrio). Diversos patrones histológicos de reacción están descritos, siendo el más frecuente el liquenoide. Presentamos una serie de 10 pacientes con reacción de hipersensibilidad a tatuaje rojo, con patrón histológico predominante dereacción granulomatosa y con moderada respuesta a tratamiento. Es importante cuando se está ante un patrón granulomatoso de reacción descartar sarcoidosis sistémica e infecciones por micobacterias
