RESUMO
Multiparameter flow cytometry (MFC)-based clonality assessment is a powerful method of diagnosis and follow-up in monoclonal gammopathy of undetermined significance (MGUS) and multiple myeloma (MM). However, the relevance of intraclonal heterogeneity in immunophenotypic studies remains poorly understood. The main objective of this work was to characterize the different immunophenotypic subclones in MGUS and MM patients and to investigate their correlation with disease stages. An 8-color MFC protocol with 17 markers was used to identify the subclones within the neoplastic compartment of 56 MGUS subjects, 151 newly diagnosed MM patients, 30 MM subjects in complete remission with detectable minimal residual disease, and 36 relapsed/refractory MM patients. Two or more clusters were observed in > 85% of MGUS subjects, 75% of stage I MM patients, and < 15% in stage III. Likewise, a significant correlation between the dominant subclone size, secondary cytogenetic features, and changes in the expression of CD27, CD44, and CD81 was detected. The loss of intraclonal equilibrium may be an important factor related with kinetics and risk of progression not well considered to date in MFC studies. The MFC strategy used in this work can provide useful biomarkers in MGUS and MM.

INTRODUCTION: The totally extraperitoneal endoscopic approach in the surgery of the inguinal hernia has experienced an important change, enabling a mesh to be implanted in the pre-peritoneal space with a comfortable access, as well as contributing to the advantages of minimally invasive surgery (less post-operative pain and a faster recovery). The objective of this study is to analyse the results of TEP endoscopic hernioplasty, mainly in the repair of bilateral hernias and recurrences or multiple recurrences. MATERIAL AND METHODS: A total of 250 TEP endoscopic hernioplasties have been performed on 150 patients in the las 5 years. The majority (63%) of the patients subjected to surgery had bilateral hernias, and 16%, recurrent. Large and complicated iguinal-scrotal hernias were excluded. A short stay regimen was followed, establishing a protocol of, analgesia, antibiotic, antithrombotic prophylaxis, and collection of post-surgical data such as analgesia demand. The patients were given a questionnaire on discharge, in which they filled in the fields on post-surgical pain, as well as an attached satisfaction questionnaire. RESULTS: The reduced need for post-surgical analgesia was noteworthy in this series, being totally unnecessary at 24h in 70 patients (46.6%), reaching 121 (80.6%) one month after surgery. There were 6 cases (4%) of reconversion, always due to opening of the peritoneal sac. There were no wound infections, 2% mild orchiepididymitis, 6 (2.4%) recurrence, and one (0.4%) inguinal neuralgia. There was a high level of satisfaction (95%). CONCLUSIONS: TEP endoscopic hernioplasty is a very effective and safe procedure in the hands of experienced surgeons with specific training. It is an interesting option in bliateral and recurrent hernia as it obtains satisfactory results in terms of postoperative pain and morbidity.

INTRODUCTION AND OBJECTIVES: Current therapeutic options for severe aortic stenosis (AS) include transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR). Our aim was to describe the prognosis of patients with severe AS after the decision to perform an intervention, to study the variables influencing their prognosis, and to describe the determinants of waiting time > 2 months. METHODS: Subanalysis of the IDEAS (Influence of the Severe Aortic Stenosis Diagnosis) registry in patients indicated for TAVI or SAVR. RESULTS: Of 726 patients with severe AS diagnosed in January 2014, the decision to perform an intervention was made in 300, who were included in the present study. The mean age was 74.0 ± 9.7 years. A total of 258 (86.0%) underwent an intervention: 59 TAVI and 199 SAVR. At the end of the year, 42 patients (14.0%) with an indication for an intervention did not receive it, either because they remained on the waiting list (34 patients) or died while waiting for the procedure (8 patients). Of the patients who died while on the waiting list, half did so in the first 100 days. The mean waiting time was 2.9 ± 1.6 for TAVI and 3.5 ± 0.2 months for SAVR (P = .03). The independent predictors of mortality were male sex (HR, 2.6; 95%CI, 1.1-6.0), moderate-severe mitral regurgitation (HR, 2.6; 95%CI, 1.5-4.5), reduced mobility (HR, 4.6; 95%CI, 1.7-12.6), and nonintervention (HR, 2.3; 95%CI, 1.02-5.03). CONCLUSIONS: Patients with severe aortic stenosis awaiting therapeutic procedures have a high mortality risk. Some clinical indicators predict a worse prognosis and suggest the need for early intervention.

The factors that influence decision making in severe aortic stenosis (AS) are unknown. Our aim was to assess, in patients with severe AS, the determinants of management and prognosis in a multicenter registry that enrolled all consecutive adults with severe AS during a 1-month period. One-year follow-up was obtained in all patients and included vital status and aortic valve intervention (aortic valve replacement [AVR] and transcatheter aortic valve implantation [TAVI]). A total of 726 patients were included, mean age was 77.3 ± 10.6 years, and 377 were women (51.8%). The most common management was conservative therapy in 468 (64.5%) followed by AVR in 199 (27.4%) and TAVI in 59 (8.1%). The strongest association with aortic valve intervention was patient management in a tertiary hospital with cardiac surgery (odds ratio 2.7, 95% confidence interval 1.8 to 4.1, p <0.001). The 2 main reasons to choose conservative management were the absence of significant symptoms (136% to 29.1%) and the presence of co-morbidity (128% to 27.4%). During 1-year follow-up, 132 patients died (18.2%). The main causes of death were heart failure (60% to 45.5%) and noncardiac diseases (46% to 34.9%). One-year survival for patients treated conservatively, with TAVI, and with AVR was 76.3%, 94.9%, and 92.5%, respectively, p <0.001. One-year survival of patients treated conservatively in the absence of significant symptoms was 97.1%. In conclusion, most patients with severe AS are treated conservatively. The outcome in asymptomatic patients managed conservatively was acceptable. Management in tertiary hospitals is associated with valve intervention. One-year survival was similar with both interventional strategies.

Objetivo: Reportar un caso clínico de lesión de la vía biliar intrapancreática tras traumatismo abdominal cerrado. Caso clínico: Paciente que acude a urgencias por intenso dolor abdominal, tras sufrir traumatismo toraco-abdominal cerrado al caer de una bicicleta. Posteriormente a su ingreso desarrolló fiebre, ictericia y patrón analítico de colestasis. Se solicitó colangiorresonancia magnética donde no se pudo valorar correctamente la vía biliar, pero se evidenció abundante líquido intraabdominal que no correspondía a sangre. Se indicó cirugía urgente ante la sospecha de lesión biliar. Se objetivó lesión de la vía biliar intrapancreática mediante colangiografía intra-operatoria y se decidió colocación de prótesis intrabiliar mediante colangiopancreatografía retrógrada endoscópica (CPRE) intraoperatoria. Conclusión: La cirugía ha sido el tratamiento convencional para la lesión de la vía biliar, pero en la actualidad la CPRE con esfinterotomía y colocación de prótesis intrabiliar es un tratamiento adecuado y resolutivo de este tipo de lesiones pudiéndose considerar como tratamiento de primera línea.
Aim: To report a clinical case of biliar injury intrapancreatic in closed abdominal trauma. Clinical case: Patient who comes to the emergency room by severe abdominal pain after suffering thoraco-abdominal blunt trauma after falling from a bicycle. After his admission he developed fever, jaundice and analytical standards of cholestasis. Magnetic resonance which failed to correctly assess the bile duct was requested but showed plenty of intra-abdominal fluid blood that did not match. Emergency surgery for suspected biliary injury was reported. Intrapancreatic injury bile duct was observed by intraoperative cholangiography and prosthesis was decided intrabiliary by intraoperative endoscopic retrograde cholangiopancreatography (ERCP). Conclusions: Surgery has been the standard treatment for bile duct injury, but now ERCP with sphincterotomy and placement of intrabiliary prosthesis is adequate and operative treatment of these injuries and can be considered as first-line treatment.
