RESUMO

BACKGROUND AND AIMS: Carvedilol has emerged as the preferred ß-blocker for treating portal hypertension. However, there is still a debate in dosing regimen, with a potential lower bioavailability in once-daily regimens. The aim of this study is to assess the acute effects of carvedilol posology in patients with clinically significant portal hypertension (CSPH), as a surrogate marker of bioavailability. METHODS: In this experimental study, 34 patients with CSPH receiving carvedilol twice daily were asked to suppress the night dose of carvedilol, creating a standardized 24-hour dose interval. Spleen stiffness measurement (SSM) and liver stiffness measurement (LSM) by transient elastography (TE) were performed, with the exact interval between the last carvedilol administration and TE measurements consistently maintained at 24 hours and compared with values prior and under treatment. RESULTS: Thirty-four patients were included, predominantly male (82.9%). SSM after suspending carvedilol for 24 hours [mean, 73.9kPa (SD, 17.0)] was significantly higher ( P < 0.001) than under treatment [mean, 56.3kPa (SD, 13.2)] and was not significantly different ( P = 0.908) from SSM prior to introduction of carvedilol [mean, 74.5kPa (SD, 12.4)]. Differences were also found in stratified analysis for carvedilol dosage, D'Amico classification stages, MELDNa scores, MELD3.0 scores, Child-Pugh class A and CSPH due to alcoholic cirrhosis. LSM after suspension was not significantly different from both under treatment and prior to treatment. CONCLUSION: The differences in SSM after skipping one dose of carvedilol show both the importance of strict adherence to the prescribed dosing regimen to achieve the expected therapeutic benefits and the impact of twice daily prescription in bioavailability throughout the day.

RESUMO

BACKGROUND: Mohs Micrographic Surgery (MMS) is commonly used to treat high-risk basal cell carcinoma (BCC). OBJECTIVES: Correlate clinicopathologic preoperative features with the number of MMS stages (primary endpoint) and margins (secondary endpoint) required for BCC complete excision. METHODS: We retrospectively analyzed BCCs treated by MMS in a 2-year period at the study's institution. Variables studied included the patient gender, age, immune status, lesion size, location, if it was a primary, recurrent, or persistent tumor, histopathologic characteristics, number of surgical stages, and amount of tissue excised. RESULTS: 116 BCCs were included. The majority (61.2%, n = 71) required a single-stage surgery for complete clearance, requiring a final margins of 3.11 ± 2.35 mm. Statistically significant differences between locations in different high-risk areas (periocular, perioral, nose, ear) and the number of MMS stages required for complete excision (p = 0.025) were found, with periocular tumours requiring the highest mean of stages (2.29 ± 0.95). An aggressive histopathology significantly influenced the number of MMS stages (p = 0.012). Any significant relation between clinicopathological features and variation in the final surgical margins was found, just certain tendencies (male patients, persistent tumor, periocular location, and high-risk histopathological tumors required larger margins). Neither patient age or tumor dimension correlated significantly with both number of MMS stages and final surgical margins. STUDY LIMITATIONS: Limitations of this study include its single-center nature with a small sample size, which limits the value of conclusions. CONCLUSION: Main factors related to a greater number of MMS stages were periocular location and high-risk histopathological subtype of the tumor.

RESUMO

Objetivo: Determinar la frecuencia de pluripatología en una Unidad de Insuficiencia Cardíaca, definir las características de los pacientes pluripatológicos y su pronóstico vital según dos modelos: el índice PROFUND y el Seattle Heart Failure Model. Material y métodos: Se han analizado de forma consecutiva los pacientes observados en la consulta de insuficiencia cardíaca de un hospital de tercer nivel durante dos meses. Se han registrado comorbilidades, categorías de pluripatología y los índices de Charlson, Barthel, Seattle Heart Failure Model y PROFUND. Resultados: Se incluyeron 246 pacientes, de los que 118 (48%) fueron pluripatológicos, con índice de Charlson 7,9±3,8 y PROFUND 3,5±7,1.La categoría de pluripatología más prevalente fue la A, seguida de la B yC. Los pluripatológicos fueron mayores (77 vs. 73 años, p=0,001), más frágiles, con mayor limitación funcional (Barthel: 84,7 vs. 96,1, p<0,001),mayor prevalencia de factores de riesgo cardiovascular y enfermedades crónicas e ingresaron más (14,4 vs. 4,7, p=0,015). La etiología más frecuente fue la cardiopatía isquémica. Los pacientes pluripatológicos tenían clase funcional más avanzada NHYA III-IV (4,2 vs. 0,8, p<0,001), NT-proBNP más elevados (2985 pg/ml vs. 1780 pg/ml, p=0,013) y precisaron mayor dosis de diuréticos (60 vs 40, p<0,001). Se verificó una concordancia en la estimativa de mortalidad entre el PROFUND y el Seattle Heart Failure Model. Conclusiones: Este estudio demuestra la elevada frecuencia de pacientes pluripatológicos en una unidad de insuficiencia cardíaca, reflejando una mayor sobrecarga asistencial y necesidad de cuidados más complejos. Se trata de una población con gran fragilidad, dependencia funcional y comorbilidad, que obliga a plantear un abordaje multidisciplinar. (AU)


Objectives: to determine the frequency of pluripathology in a Heart Failure Unit, defining the characteristics of pluripathological patients and their vital prognosis according to two models: PROFUND score and Seattle Heart Failure Model. Methods: consecutive patients from a Heart Failure Unit of a third level hospital were analized during two months. Comorbidities, pluripathology categories and Charlson, Barthel, Seattle Heart Failure Model and PROFUND scores were registered. Results: 246 patients were included, of which 118 (48%) were pluripathological, with Charlson score 7.9 ± 3.8 and PROFUND 3.5 ± 7.1.The most prevalent category of pluripathology was A, followed by B and C. The pluripathological patients were older (77 vs. 73 years, p = 0.001),more fragile, with greater functional limitation (Barthel: 84.7 vs. 96, 1,p <0.001), higher prevalence of cardiovascular risk factors and chronic diseases and admitted more (14.4 vs. 4.7, p = 0.015). The most frequent etiology was ischemic heart disease. The pluripathological patients hadmore advanced functional class NHYA III-IV (4.2 vs. 0.8, p <0.001), higherNT-proBNP (2985 pg/ml vs. 1780 pg/ml, p = 0.013) and required higherdose of diuretics (60 vs 40, p <0.001). A concordance in the mortality estimate between the PROFUND and the Seattle Heart Failure Model wasverified. Conclusion: Our study demonstrates the high frequency of pluripathological patients in a heart failure unit, population with great fragility, due to functional dependence and the association of comorbidities, that requires a multidisciplinary approach.

RESUMO

Abstract Generalized eruptive keratoacanthoma of Grzybowski is a rare variant of multiple keratoacanthomas counting with about 40 cases reported. It is a chronic and progressive disease for which none of the described therapeutic options has been entirely satisfactory. We report a case of an 83-year-old female who presented with a 3-month history of extremely pruritic, multiple, skin-coloured to erythematous to brownish, millimetric papules, with a keratotic centre. Histological examination of an incisional biopsy was consistent with the diagnosis of keratoacanthoma. The patient started acitretin 25 milligrams daily with a complete resolution of pruritus and regression of numerous lesions.

RESUMO

BACKGROUND & AIMS: Failure to control oesophago-gastric variceal bleeding (OGVB) and acute-on-chronic liver failure (ACLF) are both important prognostic factors in cirrhosis. The aims of this study were to determine whether ACLF and its severity define the risk of death in OGVB and whether insertion of rescue transjugular intrahepatic shunt (TIPS) improves survival in patients with failure to control OGVB and ACLF. METHODS: Data on 174 consecutive eligible patients, with failure to control OGVB between 2005 and 2015, were collected from a prospectively maintained intensive care unit registry. Rescue TIPS was defined as technically successful TIPS within 72 hours of presentation with failure to control OGVB. Cox-proportional hazards regression analyses were applied to explore the impact of ACLF and TIPS on survival in patients with failure to control OGVB. RESULTS: Patients with ACLF (n = 119) were significantly older, had organ failures and higher white cell count than patients with acute decompensation (AD, n = 55). Mortality at 42-days and 1-year was significantly higher in patients with ACLF (47.9% and 61.3%) than in those with AD (9.1% and 12.7%, p <0.001), whereas there was no difference in the number of endoscopies and transfusion requirements between these groups. TIPS was inserted in 78 patients (AD 21 [38.2%]; ACLF 57 [47.8%]; p = 0.41). In ACLF, rescue TIPS insertion was an independent favourable prognostic factor for 42-day mortality. In contrast, rescue TIPS did not impact on the outcome of patients with AD. CONCLUSIONS: This study shows that in patients with failure to control OGVB, the presence and severity of ACLF determines the risk of 42-day and 1-year mortality. Rescue TIPS is associated with improved survival in patients with ACLF. LAY SUMMARY: Variceal bleeding that is not controlled by initial endoscopy is associated with high risk of death. The results of this study showed that in the occurrence of failure of the liver and other organs defines the risk of death. In these patients, insertion of a shunt inside the liver to drain the portal vein improves survival.
