BACKGROUND: The nerve fibre circuits around a lesion play a major role in the spontaneous recovery process after spinal cord hemisection in rats. The aim of the present study was to answer the following question: in the re-control process, do all spinal cord nerves below the lesion site participate, or do the spinal cord nerves of only one vertebral segment have a role in repair? METHODS: First we made a T7 spinal cord hemisection in 50 rats. Eight weeks later, they were divided into three groups based on distinct second operations at T7: ipsilateral hemisection operation, contralateral hemisection, or transection...

BACKGROUND: Pectus excavatum repair (PEX) is among the most painful thoracic procedures performed. Continuous peripheral nerve blockade (CPNB) is known to be efficacious in optimizing pain control while limiting narcotic use in adult thoracic procedures. It was introduced in May 2015 as a bridge to oral pain control in children undergoing PEX. Consequently, the surgical site infection (SSI) rate increased from 2.7% to 27.7%. METHODS: SSI surveillance followed national guidelines...

Castleman's disease refers to a group of uncommon lymphoproliferative disorders which exhibit common lymph-node histological features. A 72-year-old male patient presented with signs of lower limb myositis. Detailed work-up focused initially on evaluating hematological malignancies, the presence of a solid tumor, autoimmune diseases and degenerative disorders of the peripheral nerves. Finally, a PET-CT scan was performed to exclude paraneoplastic manifestations of a primary tumor, revealing  however a tumor of the thoracic wall...

BACKGROUND: Lymphadenectomy along the left recurrent laryngeal nerve (RLN) in esophageal cancer is important for disease control (1) but requires advanced dissection skills. We previously reported a reliable method (2) for lymphadenectomy along the left RLN during thoracoscopic esophagectomy in the prone position (TEP). The goal of this method is complete dissection of the lymph nodes along the left RLN in a safe manner. METHOD: This procedure is performed for all resectable thoracic esophageal cancers...

OBJECTIVES: Residual air space problems after pulmonary lobectomy are an important concern in thoracic surgical practice, and various procedures have been applied to manage them. This study describes a novel technique using controllable paralysis of the diaphragm by localized freezing of the phrenic nerve, and assesses the effectiveness of this procedure to reduce air space after pulmonary lobectomy. METHODS: In this prospective randomized study, 207 patients who underwent lobectomy or bilobectomy and systematic mediastinal node dissection in our department between January 2009 and November 2013 were randomly allocated to a cryoneuroablation group or a conventional group...

PURPOSE: Accurate intraoperative localization of target anatomy (e.g., tumors and vertebral levels) and critical structures (e.g., nerves and vessels) is essential to safe, effective surgery. Preoperative CT/MR images can be used to identify such vital anatomy in intraoperative images through multimodality deformable registration. We proposed a deformable registration method to align preoperative MR to intraoperative CT using modality-independent neighborhood descriptors (MIND) and a Huber metric for robust registration...

Chronic abdominal wall pain is a well-documented complication of abdominal surgery. However, abdominal wall complex regional pain syndrome (CRPS) is a rare medical condition. We present a case of abdominal wall CRPS and its treatment with peripheral nerve field stimulation (PNfS). A 34-year-old female presented with right periumbilical pain for 2 years. She developed burning, sharp and stabbing pain with allodynia (extremely sensitive to wind and light touch) and erythema or pallor 2 weeks after an exploratory appendectomy...

Intervertebral disc herniation is a common cause of spinal cord compression, especially for the thoracic and thoracolumbar spinal cord, which has limited buffer space in the spinal canal. Spinal cord compression usually causes decreased sensation and paralysis of limbs below the level of compression, urinary and fecal incontinence, and/or urinary retention, which brings great suffering to the patients and usually requires surgical intervention. Thoracotomy or abdominothoracic surgery is usually performed for the thoracolumbar cord compression caused by hard intervertebral disc herniation...

After traumatic damage of the brain or spinal cord, many surviving neurons are disconnected, and recovery of function is limited by poor axon regeneration. Recent data have suggested that poly ADP-ribosylation plays a role in limiting axonal regrowth such that inhibition of poly (ADP-ribose) polymerase (PARP) may have therapeutic efficacy for neurological recovery after trauma. Here, we tested systemic administration of the PARP inhibitor, veliparib, and showed effective suppression of PARylation in the mouse CNS...

BACKGROUND: Mastalgia is a common and enigmatic condition; the cause and optimal treatment are still inadequately defined. Cervical radiculopathy, which is the result of cervical nerve root pathology often caused by spaceoccupying lesions such as cervical disc herniation, spondylosis, or osteophytosis, is frequently encountered in physical therapy. OBJECTIVES: The aim of the study was to evaluate the incidence of vertebral pathologies in patients with non-cyclic mastalgia and the efficacy of conservative treatment of these pathologies on relieving breast pain...

Intradural extramedullary nerve root metastasis is extremely unusual with only a handful of cases reported, and it presents most commonly in the thoracic and lumbosacral regions. We report the first case of metastasis to a ventral cervical nerve root in a patient with low-grade follicular thyroid carcinoma thought to be in remission for several years. Histopathology demonstrated malignant transformation and invasion of the nerve root. This case underscores that any history of malignancy regardless of staging, grading, or remission status should raise the suspicion of metastasis as it can mimic other spine and nerve sheath tumors and represent malignant transformation...

AIMS: The subcutaneous cardioverter defibrillator was designed to overcome electrode complications of transvenous defibrillation systems. While largely achieved, pocket complications have increased. Subcutaneous implantation of the pulse generator leaves it prone to erosion, extrusion, discomfort, and poor cosmesis. METHODS AND RESULTS: We use a demonstration electrode and pulse generator with fluoroscopy, prior to prepping and draping, to maximize the left ventricular mass between them...

Projection neurons play a key role in carrying long-distance information between spatially distant areas of the nervous system and in controlling motor circuits. Little is known about how projection neurons with distinct anatomical targets are organized, and few studies have addressed their spatial organization at the level of individual cells. In the paired commissural ganglia (CoGs) of the stomatogastric nervous system of the crab Cancer borealis, projection neurons convey sensory, motor, and modulatory information to several distinct anatomical regions...

Lithium at serum concentrations up to 1 mmol/L has been used in patients suffering from bipolar disorder for decades and has recently been shown to reduce the risk for ischemic stroke in these patients. The risk for stroke and thromboembolism depend not only on cerebral but also on general endothelial function and health; the entire endothelium as an organ is therefore pathophysiologically relevant. Regardless, the knowledge about the direct impact of lithium on endothelial function remains poor. We conducted an experimental study using lithium as pharmacologic pretreatment for murine, porcine and human vascular endothelium...

In decapod crustaceans, molting is controlled by the pulsatile release of molt-inhibiting hormone (MIH) from neurosecretory cells in the X-organ/sinus gland (XO/SG) complex in the eyestalk ganglia (ESG). A drop in MIH release triggers molting by activating the molting gland or Y-organ (YO). Post-transcriptional mechanisms ultimately control MIH levels in the hemolymph. Neurotransmitter-mediated electrical activity controls Ca(2+)-dependent vesicular release of MIH from the SG axon terminals, which may be modulated by nitric oxide (NO)...

OBJECTIVE: To investigate the usefulness of the perfusion index (PI) in the early detection of high spinal subarachnoid block (SAB) for cesarean section (CS). METHOD: SAB was applied in patients of CS. The patients was subdivided into two groups, according to the highest level of block: the Ce group (cervical spine level) and the Th group (thoracic spine level). The PI values in the finger and toe, and vital signs were measured at pre- and post-SAB in both groups together with SAB level...

Despite its low prevalence and incidence, considerable debate exists in the literature on thoracic outlet syndrome (TOS). From literature analysis on nerve entrapments, we realized that TOS is the second most commonly published entrapment syndrome in the literature (after carpal tunnel syndrome) and that it is even more reported than ulnar neuropathy at elbow, which, instead, is very frequent. Despite the large amount of articles, there is still controversy regarding its classification, clinical picture, diagnostic objective findings, diagnostic modalities, therapeutical strategies and outcomes...

The ventromedial hypothalamus (VMH) is known to play an important role in feeding behavior and the control of sympathetic nerve activity (SNA). We report the identification of novel neuron groups that showed oscillations on both sides of the VMH in hypothalamus slice preparations from juvenile rats of postnatal days 5-14. We detected spontaneous rhythmic burst activity with a frequency of around 0.06Hz typically in the dorsolateral region of the VMH (i.e., VMH oscillation) using optical recordings (voltage and calcium imaging), field potential recordings and intracellular membrane potential recordings...

BACKGROUND: Although reduction mammaplasty is one of the most common procedures in plastic surgery, it is associated with some serious complications, especially in cases of severe hypertrophy or advanced ptosis, including necrosis of the nipple and areola, absence of normal sensation of the nipple-areolar complex, and loss of lactational function for future nursing. A thorough understanding of the breast anatomy is vital for successful reduction mammaplasty. This article describes the blood supply and innervation of the breasts, and introduces a modified round block technique for reduction mammaplasty based on this anatomy...
