Determinants of mortality in patients with cirrhosis and uncontrolled variceal bleeding.

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.

Primary cutaneous alveolar rhabdomyosarcoma in an adolescent - A challenging diagnosis.

Primary cutaneous alveolar rhabdomyosarcoma is an extremely rare and highly aggressive soft tissue sarcoma that predominantly arises on the extremities and perineum of adolescents and young adults. Dermatologists should be aware of these tumors in order to promptly make the diagnosis and initiate treatment.

Chemotherapy-Induced Cutaneous Sclerosis: A Rare Clinical Finding.

Scleroderma-like cutaneous sclerosis has been reported as a rare adverse reaction to several drugs, including the chemotherapeutical agent paclitaxel, used in therapeutic regimens for several malignancies. The sclerosis is usually limited to the skin, most commonly presenting in the lower limbs after weeks to months of therapy but is often refractory to treatment and progresses even after discontinuation of the offending agents, with significant resulting morbidity. We report a rare case of severe cutaneous sclerosis secondary to chemotherapy with nab-paclitaxel and gemcitabine, which did not respond to treatment and led to discontinuation of chemotherapy.

Non-selective beta-blocker is associated with reduced mortality in critically ill patients with cirrhosis: A real-world study.

BACKGROUND: Apart from direct portal pressure reduction, non-selective beta-blockers (NSBB) modulate inflammatory response, which could be beneficial in patients with acute decompensation (AD). We therefore aimed to evaluate the effect of NSBB on 28-day mortality and markers of systemic inflammation in a propensity score-matched (PSM) cohort of AD patients requiring intensive care unit (ICU) admission. METHODS: Patients were recruited from registry of AD patients requiring ICU admission. Out of total 445 patients, 108 patients on NSBB before admission (NSBB use group) were PSM for age, gender, pre-admission Child-Turcotte-Pugh score and history of previous decompensation to 108 patients not on NSBB (non-NSBB use group) which served as the control group. ICU parameters, markers of systemic inflammation and 28-day mortality were compared by standard statistical tests. RESULTS: After PSM, no difference was observed in aetiology of cirrhosis, or precipitating event for AD between the groups. Pre-admission creatinine, bilirubin, international normalised ratio and haemoglobin were similar between the groups, whereas pre-admission white cell count (WCC) and neutrophil to lymphocyte ratio (NLR) was lower in NSBB-group. On admission to ICU, NSBB group had lower heart rate (p = 0.006), platelets (p = 0.012), WCC (p = 0.006), NLR (p = 0.039) and C-reactive protein (p = 0.007). Significantly more community acquired bacterial infections (p = 0.006), renal failure (p = 0.033) and higher grades of acute-on-chronic liver failure (ACLF; p = 0.012) were observed in non-NSBB group. Significantly lower 28-day (p = 0.001) and 90-day (p = 0.002) mortality was seen in NSBB group. Univariate and multivariable analysis for 28-day mortality showed that while ACLF at presentation and community acquired bacterial infection were independent negative predictors, prior NSBB use was positive predictors of survival. CONCLUSIONS: Prior use of NSBB is associated with improved 28- and 90-day mortality in critically ill cirrhosis patients with AD which is mediated probably by blunting of the inflammatory response.

The influence of carvedilol posology timing on clinically significant portal hypertension: insights from elastography measurements.

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.

Clinicopathological factors influencing the number of stages of Mohs surgery for basal cell carcinoma.

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.

Case for diagnosis. A pruritic eruption of keratotic papules over the face and neck.

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.

[Cutaneous Manifestations Associated with COVID-19: A Narrative Review]. / Manifestações Cutâneas Associadas à COVID-19: Uma Revisão Narrativa.

INTRODUCTION: COVID-19 is an infectious disease caused by the new coronavirus, SARS-CoV-2, that has spread rapidly throughout the world. This has resulted in an urgent need to obtain information regarding its pathogenesis, diagnosis and clinical manifestations. More specifically, skin manifestations, seldom reported initially, have been increasingly described. MATERIAL AND METHODS: We performed a literature search in the PubMed database, regarding cutaneous manifestations associated with COVID-19. This article describes the clinical and histological findings of the main skin lesions observed in the context of SARS-CoV-2 infection. DISCUSSION: Cutaneous manifestations associated with COVID-19 have been described in multiple retrospective and prospective studies, case series and case reports. The reported incidence reached 20.4%. Although there was substantial heterogeneity in terms of clinical patterns, the main ones include: erythematous/maculopapular, urticarial, papulovesicular, and purpuric/petechial eruptions, chilblain-like lesions and livedoid/acro-ischemic lesions. In the vast majority, the underlying pathophysiologic mechanisms are not fully understood, although histopathological findings and biomolecular studies can add relevant data. CONCLUSION: The recognition of cutaneous manifestations associated with COVID-19 is of utmost importance. They may help establishing an early diagnosis, namely in oligosymptomatic patients or when confirmatory tests are impossible to perform. Moreover, chilblain-like lesions and acro-ischemia, also seem to play an important role in terms of prognosis.

Introdução: A COVID-19, doença infeciosa causada por um novo coronavírus, SARS-CoV-2, propagou-se rapidamente pelo mundo inteiro, resultando numa necessidade emergente de obtenção de conhecimentos alusivos à sua patogénese, diagnóstico e sintomatologia. Mais especificamente, um número cada vez maior de casos relativos a manifestações cutâneas, previamente desconhecidas, tem vindo a ser descrito.Material e Métodos: Foi realizada uma pesquisa de literatura, através da base de dados PubMed, referente às manifestações dermatológicas associadas à COVID-19. O presente artigo descreve os achados clínicos e histológicos das principais lesões cutâneas observadas em contexto da infeção por SARS-CoV-2.Discussão: Manifestações cutâneas associadas à COVID-19 foram descritas em múltiplos estudos retrospetivos e prospetivos, séries de casos e casos clínicos isolados. A incidência reportada atingiu os 20,4%, verificando-se uma heterogeneidade de padrões clínicos substancial. Destes destacam-se as erupções eritematosas/maculopapulares, urticariformes, papulovesiculares, purpúricas/petequiais, lesões tipo-perniose e lesões livedóides/acro-isquémicas. O conhecimento dos mecanismos fisiopatológicos subjacentes tem vindo a ser enriquecido com achados os histológicos e de biologia molecular.Conclusão: É essencial o reconhecimento das manifestações dermatológicas associadas à COVID-19, uma vez que podem permitir o diagnóstico precoce da infeção, nomeadamente em casos oligossintomáticos ou quando não é possível a realização de testes confirmatórios. Embora menos estabelecido, lesões tipo-perniose e acro-isquémicas, parecem ter também um papel importante a nível prognóstico.
