Predictive risk model of recurrence of acute diverticulitis after the first episode.

INTRODUCTION: The recurrence of acute diverticulitis (AD) of the colon is frequent and leads to hospital readmissions and the need for elective surgery in selected cases. It is important to individualize risk factors and develop predictive tools for their identification. MATERIALS AND METHODS: This prospective observational study included 368 patients who were diagnosed with AD between 2016 and 2021 in a tertiary general university hospital during their first episode and who had a good response to antibiotic, percutaneous, or peritoneal lavage treatment. Univariate and multivariate Cox regression analyses of the variables associated with recurrence were performed. Subsequently, a predictive risk score was developed and validated through survival studies. RESULTS: After a median follow-up of 50 months, there were 71 (19.3%) cases of recurrence out of a total of 368 patients. The mean time of recurrence was 15 months, and 73.3% of cases of recurrence occurred before 2 years of follow-up. Recurrence was independently associated with presentation with colonic perforation in the antimesenteric location (HR 3.67 95% CI [1.59-8.4]) and a CRP level greater than 100 mg/dl (HR 1.69 95% CI [1.04-2.77). A score with 5 variables was created that differentiated two risk groups: intermediate risk (0-3 points), with 19% recurrence and high risk (more than 3 points), with 42% recurrence. CONCLUSIONS: The risk of recurrence after the first episode of diverticulitis can be estimated using predictive scores. The detection of high-risk patients facilitates the individualization of follow-up and treatment.

Mastitis granulomatosa idiopática. Análisis descriptivo de 10 casos en una unidad de referencia española / Idiopatic granulomatous mastitis. A descriptive analysis of 10 cases in a Spanish unit of reference

Introducción La mastitis granulomatosa es unaenfermedad infrecuente caracterizada por una inflamación granulomatosa crónica de los lobulillos mamarios. Las opciones de tratamiento siguen siendo controvertidas. Objetivo El objetivo del presente estudio fue analizar nuestra experiencia en el diagnóstico y tratamiento de las pacientes con mastitis granulomatosas, valorando la conveniencia de tratamientos quirúrgicos o tratamientos más conservadores. Material y método Se presenta un estudio retrospectivo y descriptivo de las pacientes diagnosticadas y tratadas en nuestro centro desde enero de 2010 hasta diciembre de 2018. Se analizaron las características clínicas y radiológicas de cada una, así como el tratamiento y su evolución. Resultados Los resultados del estudio fueron los siguientes: • El número de pacientes fue 10; el tiempo medio de seguimiento fue de 10,5 meses (rango 2-49 meses); la mediana de edad fue de 44,5 años (rango 31-81 años);ocho pacientes (80%)se manifestaron como tumoración palpable; el tiempo medio de duración de los síntomas fue de 6,8 meses (rango 2-24 meses); el tamaño medio de la lesión alcanzó los 23,6 mm (rango 12-40); una paciente se clasificó como bi-rads 2, 1 paciente como bi-rads 3, 1 paciente como bi-rads 4y 3 pacientes como bi-rads 5. • El tratamiento fue quirúrgico en 6 ocasiones (4 resecciones y 2 drenajes con biopsia) y médico en 4 ocasiones. Siete de las pacientes (70%) se curaron con el tratamiento efectuado (5 con cirugía y 2 con tratamiento conservador). Tres pacientes presentaron recurrencia o persistencia (1 con cirugía y 2 con tratamiento conservador). Conclusiones La mastitis granulomatosa es una enfermedad infrecuente y de causa desconocida, con tendencia a la recurrencia y cronicidad, cuyo tratamiento es todavía motivo de controversia

Introduction Granulomatous mastitis is an infrequent disease characterized by a chronic granulomatous inflammation of mammary lobules. Treatment options remain controversial. Objective The aim of the present study was to analyze our experience in the diagnosis and treatment of patients with granulomatous mastitis, assessing the convenience of surgical treatments or more conservative treatments. Materials and method This is a retrospective and descriptive study of the patients diagnosed and treated in our center from January 2010 to December 2018. We analyzed the clinical and radiological characteristics of each one, as well as the treatment and its evolution. Results • Number of patients 10; mean time of follow-up 10.5 months (range 2-49 months); median of age 44.5 years (range 31-81 years); eight patients (80%) manifested as a palpable tumor;mean duration of symptoms was 6.8 months (range 2-24 months); mean lesion size of 23.6mm (range 12-40); one patient was classified as bi-rads 2, 1 patient as bi-rads 3, 1 patient as bi-rads 4 and 3 patients as bi-rads 5. • The treatment was surgical 6 times (4 resections and 2 drainages with biopsy) and doctor on 4 occasions. Seven of the patients (70%) were cured with the treatment performed (5 with surgery and 2 with conservative treatment). Three patients presented recurrence or persistence (1 with surgery and 2 with conservative treatment). Conclusions Granulomatous mastitis is an infrequent disease of unknown cause, with a tendency to recurrence and chronicity, whose treatment is still controversial

[Linfoma anaplásico de células grandes asociado a implantes mamarios. Importancia para el cirujano]. / Anaplastic large cell lymphoma associated with breast implants. Importance for the surgeon.

El linfoma anaplásico de células grandes asociado a implantes mamarios (BIA-ALCL, breast implant associated-anaplastic large cell lymphoma) es una enfermedad infrecuente, pero el número de casos ha aumentado en los últimos años. Se puede presentar en la consulta del cirujano como un aumento del volumen mamario por derrame periprotésico o como masa capsular. El tratamiento de elección es la cirugía, con explante de las prótesis y exéresis de la cápsula periprotésica. El pronóstico, si el diagnóstico es precoz y el tratamiento es adecuado, es bueno. El objetivo del presente trabajo fue revisar la literatura científica existente hasta la fecha sobre el BIA-ALCL y poner de manifiesto la importancia que este tipo de neoplasia tiene para el cirujano.Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is an infrequent disease, although the number of cases has increased in the recent years. BIA-ALCL is revealed during medical screening as an increase in the mammary volume due to periprosthetic effusion or as a capsular mass. Preferred treatment for BIA-ALCL is surgery, with explantation of the prostheses and exeresis of the periprosthetic capsule. Prognosis, after early diagnosis and adequate treatment, is good. The objective of the present work was to review the existing scientific literature on BIA-ALCL and to show the importance of this type of neoplasia for a successful treatment.

[Diabetic mastopathy. Features in four patients]. / Mastopatía diabética. Estudio de 4 pacientes.

Diabetic mastopathy is a clinicopathologic entity that represents less than 1% of benign breast disease and is mainly related to type 1 diabetes. The pathogenesis is unknown but the most convincing hypothesis postulates extracellular collagen deposit and predominantly B-cell inflammation with autoimmune response. The clinical, radiological and pathological features of four patients with diabetic mastopathy are presented.
