OBJECTIVE To predict which intercostal artery supplies a tumor by examining the spatial relationship between hepatocellular carcinoma (HCC) and the intercostal artery feeding the tumor on transverse computed tomography (CT) images. MATERIALS AND METHODS Between January 2000 and September 2009, 46 intercostal arteries supplying HCCs smaller than 4 cm were noted in 44 patients, and CT scans and...

Previous studies from our laboratory have shown that the cardiac sympathetic afferent reflex is enhanced in dogs with experimental heart failure. The aim of the present study was to determine if the central gain of the cardiac sympathetic afferent reflex was also enhanced in dogs with heart failure. Fifteen dogs with pacing-induced heart failure were used in this study. Seventeen sham-operated ...

introduction lung herniation following blunt chest trauma is extremely rare and only a few hundred cases of this pathology have been reported in the english language medical literature. this type of lung hernia is divided into intercostal, parasternal, or supraclavicular subtypes based on the exact location of the chest wall defect. traumatic intercostal lung hernia is even more uncommon. delay...

PURPOSE Knowledge of the anatomic variations of the posterior intercostal artery (PICA) and its major branches is important during transthoracic procedures and surgery. We aimed to identify the anatomic features and variations of the lateral intercostal artery perforator (LICAP) of the PICA with selective PICA arteriography. METHODS We retrospectively evaluated 353 PICAs in 75 patients with s...

Introduction Traumatic total brachial plexus injury (TTBPI) is a severe and disabling form of injury. Reconstructive modalities are complex and outcomes are variable. This is mainly because of the multitude of functions lost and relative scarcity of donor nerves to reconstruct these functions. As a result, there are several different opinions and ideologies on TTBPI. Several papers report the f...

Sonic hedgehog (Shh) specifies the identity of both motor neurons (MNs) and interneurons with morphogen-like activity. Here, we present evidence that the homeodomain factor HB9 is critical for distinguishing MN and interneuron identity in the mouse. Presumptive MN progenitors and postmitotic MNs express HB9, whereas interneurons never express this factor. This pattern resembles a composite of t...

Primitive neuroectodermal tumours was originally described by Askin et al. [1]. It is commonly found in children and young females. It frequently appears as a chest wall mass and grows rapidly to involve the neighboring pleura. The histogenesis of this rare tumour is uncertain and it is believed to be arising from the intercostal nerves. It exclusively arises from one hemi thorax and progresses...

Tumors of the superior pulmonary sulcus (Pancoast tumors) are bronchogenic carcinomas that occur at the thoracic inlet and typically involve, by direct extension, the lower trunks of the brachial plexus, the intercostal nerves, the stellate ganglion, and adjacent ribs and vertebrae. These tumors are rare, comprising 5% of all lung cancers. Treatment of Pancoast tumors has traditionally consiste...

Anterior cutaneous nerve entrapment syndrome (ACNES) is a commonly underdiagnosed and undertreated chronic state of pain. This syndrome is characterized by the entrapment of the cutaneous branches of the lower thoracoabdominal intercostal nerves at the lateral border of the rectus abdominis muscle, which causes severe, often refractory, chronic pain. This narrative review aims to identify the p...
