Non-tuberculous mycobacteriosis of the liver responsive to empiric therapy.

This case demonstrates that clinical and pathological suspicion of NTM could be sufficient to start an empiric treatment even when microbiological isolation is unavailable. Moreover, disseminated mycobacteriosis may underlie an occult aggressive neoplasm.

Hepatic vein transit time of second-generation ultrasound contrast agent: new tool in the assessment of portal hypertension.

Purpose: It has been demonstrated that Doppler waveform of the hepatic vein (normally triphasic) is transformed into a biphasic or monophasic waveform in cirrhotic patients. The compressive mechanism of liver tissue has been considered up till now the cause of this change. Moreover, cirrhotics show, after USCA injection, a much earlier HVTT due to intrahepatic shunts.

Radiofrequency ablation of pancreatic neuroendocrine tumors: a pilot study of feasibility, efficacy, and safety.

Objective: This study aimed to assess the feasibility, safety, and efficacy of radiofrequency ablation (RFA) of pancreatic neuroendocrine tumors (PNETs).

Methods: We performed RFA on 10 patients (7 women) aged 38 to 75 years with histologically diagnosed PNETs (secreting in 3 cases) who could not or would not undergo surgical resection. Tumor nodules (diameter, 0.

Botulinum toxin A versus B in sialorrhea: a prospective, randomized, double-blind, crossover pilot study in patients with amyotrophic lateral sclerosis or Parkinson's disease.

Background: Either botulinum toxins (BoNTs) A and B have been used for improving drooling in different neurological conditions.

Methods: Consecutive patients affected by Amyotrophic Lateral Sclerosis (ALS) or Parkinson's Disease (PD) accompanied by severe drooling were randomized to receive botulinum neurotoxin type A (BoNT-A) or B (BoNT-B) injections into the salivary glands. Following the first treatment, when sialorrhea returned to baseline (at least three months after the first injection), subjects were re-treated with the other serotype.
