Low-grade fever: how to distinguish organic from non-organic forms.

BACKGROUND AND AIM: Low-grade fever (LGF) is defined as a body temperature between 37.5 and 38.3 degrees C, which is below the classical value reported for fever of unknown origin (FUO). We attempted to characterise its epidemiology, aetiology and clinical aspects to improve the methodological approach to diagnosis. DESIGN AND METHODS: We reviewed and evaluated a survey of patients with LGF, followed as outpatients of our Department, a tertiary referral centre from 1997 to 2008. The same classifications were applied for classical FUO, and in the patients diagnosed with LGF, we also investigated for habitual hyperthermia (HH). RESULTS: Seventy-three patients were selected and divided into two groups: group A included 32 patients classified with organic fever and group B included 41 patients with HH. Aetiology of organic LGF was: infectious disease 59%; neoplasm 3.1%; inflammatory non-infectious disease 6.2%; miscellaneous 18.7%; undiagnosed 12.5%. Mean age was significantly higher in the organic fever than in the HH group (p < 0.02). Splenomegaly and loss of weight were significantly associated with organic fever (p < 0.05), while dizziness and general malaise were associated with HH. Lack of any pathological signs at physical examination was significantly more frequent in HH (p < 0.0001). Among the biochemical tests, white blood cells and C-reactive protein were more frequently above normal limits in group A than in group B (p < 0.05). CONCLUSIONS: In our experience, LGF requires the same methodological diagnostic approach as FUO, because there is no relationship between body temperature values and the severity of the underlying diseases, and the aetiological spectrum is also the same.

Echocardiographic evaluation of mitral tethering for 'chordal cutting' procedure.

'Chordal cutting' is a recently proposed surgical option for the treatment of functional mitral regurgitation due to leaflet tethering. With this technique the surgeon sections second order chordae, restores leaflet's convexity towards the left atrium and eliminates mitral incompetence. Preoperative assessment of tethering mechanism, degree of leaflet distortion, surface of coaptation, annular dilation, origin and quantification of valve incompetence by echocardiographic means is essential in indicating this surgical option. Intraoperative transesophageal evaluation is crucial to assess the morphology and the absence or degree of residual incompetence after procedure.

Comparison between alcohol- and hepatitis C virus-related hepatocellular carcinoma: clinical presentation, treatment and outcome.

BACKGROUND: Hepatitis C virus (HCV) and alcohol abuse are the main risk factors for hepatocellular carcinoma (HCC) in Western countries. AIM: To investigate the role of alcoholic aetiology on clinical presentation, treatment and outcome of HCC as well as on each Barcelona Clinic Liver Cancer (BCLC) stage, as compared to HCV-related HCCs. METHODS: A total of 1642 HCV and 573 alcoholic patients from the Italian Liver Cancer (ITA.LI.CA) database, diagnosed with HCC between January 2000 and December 2012 were compared for age, gender, type of diagnosis, tumour burden, portal vein thrombosis (PVT), oesophageal varices, liver function tests, alpha-fetoprotein, BCLC, treatment and survival. Aetiology was tested as predictor of survival in multivariate Cox regression models and according to HCC stages. RESULTS: Cirrhosis was present in 96% of cases in both groups. Alcoholic patients were younger, more likely male, with HCC diagnosed outside surveillance, in intermediate/terminal BCLC stage and had worse liver function. After adjustment for the lead-time, median (95% CI) overall survival (OS) was 27.4 months (21.5-33.2) in alcoholic and 33.6 months (30.7-36.5) in HCV patients (P = 0.021). The prognostic role of aetiology disappeared when survival was assessed in each BCLC stage and in the Cox regression multivariate models. CONCLUSIONS: Alcoholic aetiology affects survival of HCC patients through its negative effects on secondary prevention and cancer presentation but not through a greater cancer aggressiveness or worse treatment result. In fact, survival adjusted for confounding factors was similar in alcoholic and HCV patients.

Years of life that could be saved from prevention of hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) causes premature death and loss of life expectancy worldwide. Its primary and secondary prevention can result in a significant number of years of life saved. AIM: To assess how many years of life are lost after HCC diagnosis. METHODS: Data from 5346 patients with first HCC diagnosis were used to estimate lifespan and number of years of life lost after tumour onset, using a semi-parametric extrapolation having as reference an age-, sex- and year-of-onset-matched population derived from national life tables. RESULTS: Between 1986 and 2014, HCC lead to an average of 11.5 years-of-life lost for each patient. The youngest age-quartile group (18-61 years) had the highest number of years-of-life lost, representing approximately 41% of the overall benefit obtainable from prevention. Advancements in HCC management have progressively reduced the number of years-of-life lost from 12.6 years in 1986-1999, to 10.7 in 2000-2006 and 7.4 years in 2007-2014. Currently, an HCC diagnosis when a single tumour <2 cm results in 3.7 years-of-life lost while the diagnosis when a single tumour ≥ 2 cm or 2/3 nodules still within the Milan criteria, results in 5.0 years-of-life lost, representing the loss of only approximately 5.5% and 7.2%, respectively, of the entire lifespan from birth. CONCLUSIONS: Hepatocellular carcinoma occurrence results in the loss of a considerable number of years-of-life, especially for younger patients. In recent years, the increased possibility of effectively treating this tumour has improved life expectancy, thus reducing years-of-life lost.

[Acute ischemia of the optic nerve after retrobulbar injection]. / Ischémie aiguë du nerf optique après injection rétrobulbaire.

The authors present a case of acute amaurosis following a retrobulbar injection of anaesthetic. The patient was a mononephric subject in hemodialytic treatment receiving, therefore, a daily therapy by heparin. The ophthalmoscopic feature reveals a pale optic disk oedema, normal arteries and tortuous veins; the fluorescein angiography confirms the papillary oedema and the normal arterial fillings. The echographic picture shows an hematic collection through the nerve sheath. The authors analyze the main pathogenic hypothesis of the amaurosis which should be ascribed to an acute ischemia of the disk caused by the hematoma formed through the nerve sheath. The role of the general conditions of the patient, mononephric in hemodialytic treatment, is emphasized as a possible risk factor even for a retrobulbar injection.
