Spectrum of abdominal imaging findings in histiocytic disorders.

OBJECTIVES: The present article provides an overview of the spectrum of abdominal findings of histiocytic disorders that may be observed in multimodality imaging illustrated by clinical cases from our Imaging Center. METHODS: We will review abdominal findings of Langerhans cell histiocytosis, Rosai-Dorfman disease, Erdheim-Chester disease, and hemophagocytic syndrome illustrated by clinical cases from our imaging department with histologic correlation. RESULTS: Abdominal involvement of histiocytic disorders is rare and may occur in the liver, biliary tract, kidney, retroperitoneum, kidney, gastrointestinal tract, and lymph nodes. CONCLUSION: Histiocytic disorders encompass a group of rare diseases with a wide range of manifestations in which the abdominal involvement is quite infrequent. The role of the radiologist is to report the major imaging findings and the differential diagnosis; however, the imaging features are unspecific and biopsy usually is necessary to establish the definitive diagnosis.

In-hospital death in acute coronary syndrome was related to admission glucose in men but not in women.

BACKGROUND: Admission hyperglycaemia is associated with mortality in patients with acute coronary syndrome (ACS), but controversy exists whether hyperglycaemia uniformly affects both genders. We evaluated coronary risk factors, gender, hyperglycaemia and their effect on hospital mortality. METHODS: 959 ACS patients (363 women and 596 men) were grouped based on glycaemia ≥ or < 200 mg/dL and gender: men with glucose < 200 mg/dL (menG-); women with glucose < 200 mg/dL (womenG-); men with glucose ≥ 200 mg/dL (menG+); and women with glucose ≥ 200 mg/dL (womenG+). A logistic regression analysis compared the relation between gender and glycaemia groups and death, adjusted for coronary risk factors and laboratory data. RESULTS GROUP: menG- had lower mortality than menG + (OR = 0.172, IC95% 0.062-0.478), and womenG + (OR = 0.275, IC95% 0.090-0.841); womenG- mortality was lower than menG + (OR = 0.230, IC95% 0.074-0.717). No difference was found between menG + vs womenG + (p = 0.461), or womenG- vs womenG + (p = 0.110). Age (OR = 1.067, IC95% 1.031-1.104), EF (OR = 0.942, IC95% 0.915-0.968), and serum creatinine (OR = 1.329, IC95% 1.128-1.566) were other independent factors related to in-hospital death. CONCLUSIONS: Death was greater in hyperglycemic men compared to lower blood glucose men and women groups, but there was no differences between women groups in respect to glycaemia after adjustment for coronary risk factors.

Emergency service admission time and in-hospital mortality in acute coronary syndrome.

BACKGROUND: The relationship between admission time to an emergency service and in-hospital outcomes in acute coronary syndrome (ACS) is controversial. Admission during off-hours would be associated with worse prognosis. OBJECTIVE: To assess the influence of admission time on prolonged hospitalization and mortality for ACS patients, regarding regular hours (7AM-7PM) and off-hours (7PM-7AM). METHODS: The study assessed prospectively 1,104 consecutive ACS patients. In-hospital mortality and length of hospital stay ≥ 5 days were the outcomes analyzed. RESULTS: Admission during regular hours was greater as compared with that during off-hours (63% vs. 37%; p < 0.001). Unstable angina was more prevalent during regular hours (43% vs. 32%; p < 0.001), while non-ST-segment elevation myocardial infarction (NSTEMI) was during off-hours (33% vs. 43%; p = 0.001). Differences in neither mortality nor length of hospital stay were observed in the time periods studied. Predictive factors for length of hospital stay ≥ 5 days were as follows: age [OR 1.042 (95%CI: 1.025 - 1.058), p < 0.001]; ejection fraction (EF) [OR 0.977 (95%CI: 0.966 - 0.988), p < 0.001]; NSTEMI [OR 1.699 (95%CI: 1.221 - 2.366), p = 0.001]; and smoking [OR 1.723 (95%CI: 1.113 - 2.668), p = 0.014]. Predictive factors for in-hospital mortality were as follows: age [OR 1.090 (95%CI: 1.047 - 1.134), p < 0.001]; EF [OR 0.936 (95%CI: 0.909 - 0.964), p < 0.001]; and surgical treatment [OR 3.781 (95%CI: 1.374 - 10.409), p = 0.01]. CONCLUSION: Prolonged length of hospital stay and in-hospital mortality in ACS patients do not depend on admission time.

Hora da admissão na unidade de emergência e mortalidade hospitalar na síndrome coronária aguda / Emergency service admission time and in-hospital mortality in acute coronary syndrome

FUNDAMENTO: Há controvérsias sobre a hora da admissão e os desfechos hospitalares da síndrome coronária aguda (SCA). A admissão em horários não regulares seria associada ao pior prognóstico dos pacientes. OBJETIVO: Analisar a influência da hora da admissão na internação prolongada e na mortalidade de pacientes com SCA, segundo os períodos diurno (das 7h às 19h) e noturno (das 19h às 7h). MÉTODOS: Foram avaliados, prospectivamente, 1.104 pacientes consecutivos com SCA. O óbito intra-hospitalar e a internação igual ou superior a cinco dias foram os desfechos analisados. RESULTADOS: A admissão no período diurno foi maior em comparação ao noturno (63 por cento vs. 37 por cento; p < 0,001). A angina instável foi mais prevalente no período diurno (43 por cento vs. 32 por cento; p < 0,001) e o infarto sem supradesnivelamento do segmento ST (IAMssST) no noturno (33 por cento vs. 43 por cento; p = 0,001). Não se observaram diferenças na mortalidade e no tempo de internação nos períodos estudados. Os fatores de predição de internação igual ou superior a cinco dias foram: idade [OR 1,042 (IC 95 por cento 1,025 - 1,058), p < 0,001]; fração de ejeção (FE) [OR 0,977 (IC 95 por cento 0,966 - 0,988), p < 0,001]; IAMssST [OR 1,699 (IC 95 por cento 1,221 - 2,366), p = 0,001]; e tabagismo [OR 1,723 (IC 95 por cento 1,113 - 2,668), p = 0,014]. Para o óbito intra-hospitalar, foram: idade [OR 1,090 (IC 95 por cento 1,047 - 1,134), p < 0,001]; FE [OR 0,936 (IC 95 por cento 0,909 - 0,964), p < 0,001]; e tratamento cirúrgico [OR 3,781 (IC 95 por cento 1,374 - 10,409), p = 0,01]. CONCLUSÃO: A internação prolongada e óbito intra-hospitalar em pacientes com SCA independem do horário de admissão.

CONCLUSION: Prolonged length of hospital stay and in-hospital mortality in ACS patients do not depend on admission time.
