Thoracic paravertebral blockade is a simple and easy-to-learn technique with a low incidence of complications. It should be considered as a safe alternative to thoracic epidural analgesia/anaesthesia. We reviewed the techniques of thoracic paravertebral blockade with special interest to ultrasound guidance.

The sensitivity of transabdominal ultrasound in the diagnosis of ureterolithiasis.
The ultrasonographic diagnosis of renal lithiasis colic is suggested by the existence of hydronephrosis, but the certainty is given by the direct visualization of the ureteral calculus. The aim of this study is to assess the performance of ultrasound in identifying ureteral calculi compared to other imaging methods (abdominal X-ray, urography and computed tomography). ⋯ Ultrasound is a sensitive method for detecting UL in renal colic and can be used as the initial imaging method in investigating these patients. The presence or absence of hydronephrosis can not be considered as a discriminatory factor for the diagnosis of ureterolithiasis.

Hepatoblastoma represents the child's most frequent malignant hepatic tumor. We present the case of a one-year old prematurely born patient with an abdominal mass. Ultrasound and CT scan demonstrated a solid hepatic tumor. ⋯ Pathological examination revealed complete excision of a mixed hepatoblastoma. Hepatic tumor at a child under 3 years old correlated with elevated serum alpha fetoprotein and thrombocytosis are almost patognomonic for hepatoblastoma. Complete surgery is the mainstay of therapy in hepatoblastoma.
