One stop shop approach for the diagnosis of liver hemangioma

Hepatic hemangioma is usually detected on a routine ultrasound examination because of silent clinical behaviour. The typical ultrasound appearance of hemangioma is easily recognizable and quickly guides the diagnosis without the need for further investigation. But there is also an entire spectrum of atypical and uncommon ultrasound features and our review comes to detail these particular aspects. An atypical aspect in standard ultrasound leads to the continuation of explorations with an imaging investigation with contrast substance [ultrasound/ computed tomography/or magnetic resonance imaging (MRI)]. For a clinician who practices ultrasound and has an ultrasound system in the room, the easiest, fastest, non-invasive and cost-effective method is contrast enhanced ultrasound (CEUS). Approximately 85% of patients are correctly diagnosed with this method and the patient has the correct diagnosis in about 30 min without fear of malignancy and without waiting for a computer tomography (CT)/MRI appointment. In less than 15% of patients CEUS does not provide a conclusive appearance; thus, CT scan or MRI becomes mandatory and liver biopsy is rarely required. The aim of this updated review is to synthesize the typical and atypical ultrasound aspects of hepatic hemangioma in the adult patient and to propose a fast, non-invasive and cost-effective clinical-ultrasound algorithm for the diagnosis of hepatic hemangioma.     

Transperitoneal laparoscopic right sympathectomy

Laparoscopic lumbar transperitoneal sympathectomy represents the miniinvasive approach of laterocolic procedure Adson-Diez. It is suitable to laparoscopic surgery, has a good reproducibility and it is more advantageous than total retroperitoneal approach because of a larger working space.     

Blood cyclosporine level soon after kidney transplantation is a major determinant of rejection: insights from the Mycophenolate Steroid-Sparing Trial

Target organs express antigens directly recognized by antigen-specific T cells, thereby precipitating rejection. When early T-cell activation is inhibited, there is a low risk of rejection. We sought to determine the predictive values of serial posttransplant blood cyclosporine trough (C(0)) concentrations to minimize the risk for a first rejection episode compared with 2-hour postdose (C(2)) drug concentrations. The final aim of the study was to identify a concentration range for the best predictive pharmacokinetic parameter that should be targeted to reduce the risk of rejection. This possibility was explored in 334 de novo kidney transplant recipients who participated in the prospective, multicenter Mycophenolate Steroid-Sparing Trial. Among measurements performed during the first 6 months postsurgery, cyclosporine C(0) levels measured early after transplantation were the strongest predictor of acute graft rejection. Levels within 300 to 440 ng/mL were associated with the lowest risk of rejection, while patients with levels lower than 300 ng/mL showed a more than double risk. Cyclosporine trough values predicted allograft rejection with an accuracy of 74%, while C(2) levels had no predictive value. These findings underline the need to target cyclosporine therapy early posttransplant to modulate T-cell activation.     

Arrhythmic cardiomyopathy. Case report

An 11 year-old boy was admitted with incessant sinus node reentrant tachycardia and secondary dilated arrhythmic cardiomyopathy, treated by radiofrequency ablation. Two years later he was admitted with incessant automatic atrial tachycardia and arrhythmic cardiomyopathy; a second catheter ablation procedure failed, but the third one, performed four month later, was successfully and resulted in a restoration of a normal sinus rhythm and a complete regression of arrhythmic cardiomyopathy.     

Complications of intracerebral hemorrhage caused by arterial hypertension

Intracerebral hematoma represent a frequent complication of hypertension. It is accompanied by significant mortality and complications. It is mainly a surgical condition but we prefer conservative therapeutic options in cases where feasible. The conservative treatment gives better results but surgery becomes obsolete in cases when medical treatment fails.     

Diurnal variation in total plasma tryptophan in controls and in depression

Circadian rhythms of total tryptophan were investigated by assays of hourly blood samples over 25 h. The study population consisted of four endogenously depressed patients investigated in the absence of any treatment and six healthy controls. The abnormalities detected by statistical analyses in untreated depression consisted mainly of amplitude reduction; the phase positions of the depressed patients were similar to those of the controls.
