Persistent left superior vena cava is a rare vascular anatomical variant. Although ultrasonography has facilitated the process of central venous catheterization, it cannot be used to locate the tip of a catheter. Postprocedure chest X-ray is desirable for locating the course and tip of the catheter. In our case, initial ultrasonography demonstrated the absence of the right internal jugular vein. This prompted insertion of a central venous catheter on the left side of the neck in the presence of normal vascular anatomy...

Lung ultrasonography is a well established, user-friendly and easy-to-use technique that can be used in the evaluation of several pathological conditions affecting the lung. Adding lung ultrasonography to traditional echocardiography provides an integrated cardiopulmonary ultrasound analysis. The simultaneous collection of information about the heart and the lungs can help physicians to investigate acute and chronic cardio-pulmonary conditions within a noninvasive, single-probe and all-in-one examination, not exposing the patient to the danger of ionizing radiation...

In this article, we discuss the emerging role of lung point-of-care ultrasonography for regional anesthesiologists and pain management specialists. Lung ultrasonography is a well-established clinical tool that is used on a routine basis in emergency rooms and critical care units internationally to evaluate patients with respiratory distress; however, its benefits to the regional anesthesiologist and pain specialist are not as well known and are practiced less frequently. This review article covers the clinical evidence in support of lung point-of-care ultrasonography as a rapid and superior tool to traditional imaging modalities such as chest radiography and fluoroscopy...

Minsun Jung, Sung-Hye Park
Thanatophoric dysplasia (TD), the most common lethal skeletal dysplasia, is a de novo genetic disease caused by a mutation in the fibroblast growth factor receptor 3 (FGFR3) gene. "Thanatophoric" means "dead bearing" in Greek. Because FGFR3 is the main modulator of bone maturation, typical features of TD include short extremities, curved femur, clover-leaf skull, small narrow chest, and platyspondyly. TD can be classified into two subgroups according to the morphologic findings, with prominent curved femur suggesting type I TD (TD 1) and with marked clover-leaf skull and relatively straight long bones, favoring type II TD (TD 2)...

BACKGROUND: Pleural effusion adversely affects the pressuregenerating capacity of the diaphragm. It uncouples the lung and chest wall, which may result in diaphragmatic dysfunction. Information on the effects of effusion drainage on diaphragmatic function is limited, but several studies report relief of dyspnoea after drainage, which was attributed to improved diaphragmatic mechanics, even if this issue was never formally addressed. OBJECTIVE: To investigate the effect of drainage of unilateral pleural effusion on diaphragmatic function...

Heteropagus twins are an extremely rare event with an incidence of 1-2 million live births that represents, sometimes, a real challenge for paediatric surgeons. The majority of cases have complete or partial duplication of the pelvis and/or lower extremities. Thoracic heteropagus conjoined twins is a rare condition in which a grossly defective foetus (the parasite) is attached to the thorax of the main foetus (the autosite). We describe a case of a parasitic heteropagus attached at the chest wall with a rare presentation of giant exomphalos on the autosite...
