We present a case of a 51-year-old man who was injured in a bicycle accident. His main injury was an unstable fracture of the cervical and thoracic vertebral column. Several hours after his arrival to the hospital the patient underwent open reduction and internal fixation (ORIF) of the cervical and thoracic spine. The patient was hospitalized in our critical care unit for 99 days. During this time patient had several episodes of severe bradycardia and asystole; some were short with spontaneous return to sinus and some required pharmacological treatment and even Cardiopulmonary Resuscitation (CPR)...

A 6-year-old neutered female Jack Russell terrier was investigated for sudden onset prechiasmatic bilateral blindness, left circling, reduced proprioception in the right pelvic limb and right facial allodynia. Electroretinography was normal. Magnetic resonance imaging (MRI) examination revealed that the right optic nerve and the optic chiasm were hyperintense on diffusion weighted imaging and hypointense on apparent diffusion coefficient map consistent with ischemic optic neuropathy. A concurrent lacunar infarct was detected in the left rostral colliculus...

OBJECTIVE Neurogenic thoracic outlet syndrome (nTOS) is an uncommon compression syndrome of the brachial plexus that presents with pain, sensory changes, and motor weakness in the affected limb. The authors reviewed the clinical presentations and outcomes in their series of pediatric patients with surgically treated nTOS over a 6-year period. METHODS Cases of nTOS in patients age 18 years or younger were extracted for analysis from a prospective database of peripheral nerve operations. Baseline patient characteristics, imaging and neurophysiological data, operative findings, and outcomes and complications were assessed...

INTRODUCTION: The parathyroid gland was first identified in the Indian rhinoceros in 1849 by Sir Richard Owen. We performed a necropsy in an Indian rhinoceros, recapitulating Owen's dissection and display what appear to be the initial identification of the recurrent laryngeal nerve in situ and the anatomy and histology of the largest rhinoceros parathyroid glands yet identified. MATERIALS AND METHODS: Patrick T. Rhino, a 41-year-old Indian rhinoceros was born in 1974...

Recurrent laryngeal nerve injury can develop following cervical or thoracic surgery; however, few reports have described intraoperative recurrent laryngeal nerve monitoring. Consensus regarding the use of this technique during thoracic surgery is lacking. We used intraoperative recurrent laryngeal nerve monitoring in a patient with contralateral vocal cord paralysis who was scheduled for completion pneumonectomy. This case serves as an example of intraoperative recurrent laryngeal nerve monitoring during thoracic surgery and supports this indication for its use...

Parrot bornaviruses (PaBVs) are the causative agents of proventricular dilatation disease, however key aspects of its pathogenesis, such as route of infection, viral spread and distribution, and target cells remain unclear. Our study aimed to track the viral spread and lesion development at 5, 10, 20, 25, 35, 40, 60, 80, 95 and 114 dpi using histopathology, immunohistochemistry, and RT-PCR. After intramuscular inoculation of parrot bornavirus 2 (PaBV-2) in the pectoral muscle of cockatiels, this virus was first detected in macrophages and lymphocytes in the inoculation site and adjacent nerves, then reached the brachial plexus, centripetally spread to the thoracic segment of the spinal cord, and subsequently invaded the other spinal segments and brain...

The development of formalin-free fixatives is an urgent issue in gross anatomy because of the health hazard and the tissue-hardening actions of formalin. We recently identified the fixative, antimicrobial, and preservative effects of N-vinyl-2-pyrrolidone (NVP), a precursor of the water-soluble macromolecular polymer polyvinylpyrrolidone, in animal experiments. The aim of the present study is to investigate whether NVP solution can be used as an alternative to formalin in human cadaveric dissection. Twelve donated cadavers were infused with NVP via the femoral and common carotid arteries using a peristaltic pump...

PURPOSE: In this article, we summarize our work on understanding the influence of cervical sagittal malalignment on the mechanics of the cervical spine. METHODS: Biomechanical studies were performed using an ex vivo laboratory model to study the kinematic and kinetic response of human cervical spine specimens in the setting of cervical sagittal imbalance. The model allowed controlled variations of C2-C7 Sagittal Vertical Alignment (C2-C7 SVA) and T1-Slope so that clinically relevant sagittally malaligned profiles could be prescribed, while maintaining horizontal gaze, and their biomechanical consequences studied...

Schwanomatosis is the third most common form of neurofibromatosis. Schwanomatosis affecting the vagus nerve is particularly rare. In this report, we describe an extremely rare case bilateral vagus nerve schwanomatosis in a 45-year-old male patient. The patient initially presented with bilateral neck tumors and hoarseness arising after thoracic surgery. We performed left neck surgery in order to diagnose and resect the remaining tumors followed by laryngeal framework surgery to improve vocal cord closure and symptoms of hoarseness...

BACKGROUND: Reducing sympathetic efferent outflow from the stellate ganglia (SG) may be antiarrhythmic. OBJECTIVE: To test the hypothesis that chronic thoracic subcutaneous nerve stimulation (ScNS) could reduce SG nerve activity (SGNA) and control paroxysmal atrial tachycardia (PAT). METHODS: We performed thoracic ScNS in 8 dogs while monitoring the SGNA, vagal nerve activity (VNA) and subcutaneous nerve activity (ScNA). An additional 3 dogs were used for sham stimulation as controls...

In recent years, the search for a less invasive and thus, less painful approach has driven technical innovation in modern thoracic surgery. In this context, subxiphoid uniportal approach has emerged as an alternative to avoid intercostal space manipulation and decrease postoperative pain and intercostal nerve chronic impairment. Subxiphoid uniportal major lung resections have been safe and effective procedures when performed by experienced surgeons even in complex cases or unexpected intraoperative situations...

Currently, surgical techniques that are less invasive than conventional median sternotomy are used for thymectomy in the treatment of myasthenia gravis and anterior mediastinal tumors as no sternal incision is required. We reported on a subxiphoid single-port thymectomy using CO2 insufflation, which has the following advantages: (I) the field of view offered by the camera scope inserted from the midline of the body helps confirm the location of the superior pole of the thymus and bilateral phrenic nerves; (II) there is minimal pain and no intercostal neuropathy occurs as intercostal spaces are not traversed; and (III) cosmetic outcomes are excellent...

Video-assisted thoracic surgery (VATS) surgery has seen an evolution from multiple ports to uniportal and finally subxiphoid uniportal recently. In traditional VATS surgery, the instruments and the thoracoscope enter the thoracic cavity through two to four operating ports on the lateral chest wall, which can cause chronic pain and chest wall numbness. However single-portal VATS surgery could potentially cause similar problems as the port is placed in between the ribs. In March 2015 Liu et al. reported a VATS bilateral pulmonary metastasectomy and right middle lobectomy via a subxiphoid uniportal technique...

The vagus nerve is responsible for the parasympathetic innervation of the major thoracic and abdominal organs. It also carries sensory afferent fibres from these viscera and reaches different brain structures. These connections have proven useful in the treatment of different diseases. Afferent stimulation of the left vagus nerve is used to treat epilepsy and major depression, and stimulation of the right vagus nerve is being tried for the treatment of heart failure. The device used for the therapy delivers intermittent stimuli...

Tracheal diverticulum, a benign entity characterized by single or multiple invaginations of the tracheal wall, is commonly asymptomatic and detected incidentally. We report the case of a 76-year-old man with a tracheal diverticulum who underwent thoracoscopic esophagectomy with a three-field lymphadenectomy for middle thoracic esophageal cancer. The tracheal diverticulum was located at the right posterolateral region of the trachea, which overlapped the region of dissection of the right recurrent laryngeal nerve lymph nodes...

BACKGROUND: Minimally invasive esophagectomy was first introduced as a new technique for esophageal cancer treatment 20 years ago. Performing this procedure in the lateral-prone position is the most appropriate method. Since May 2013, our center has performed 124 esophageal cancer operations using this procedure. Herein, we share our experience. METHODS: We retrospectively reviewed 124 consecutive patients who had received minimally invasive esophagectomy in the lateral-prone position from May 2013 to June 2017...
