Sensory Innervation of Human Bone: An Immunohistochemical Study to Further Understand Bone Pain.

Skeletal diseases and their surgical treatment induce severe pain. The innervation density of bone potentially explains the severe pain reported. Animal studies concluded that sensory myelinated A∂-fibers and unmyelinated C-fibers are mainly responsible for conducting bone pain, and that the innervation density of these nerve fibers was highest in periosteum.

An Anatomical Study to the Branching Pattern of the Posterior Interosseous Nerve on the Dorsal Side of the Hand.

Partial denervation of the wrist can benefit patients with chronic wrist pain. A complication of partial denervation is loss of proprioception and hypesthesia on the dorsal side of the hand. Our aim is to evaluate whether the sensory branches of the posterior interosseous nerve could contribute to the loss of proprioception and sensation.

Low-Fat Tube Feeding After Esophagectomy Is Associated With a Lower Incidence of Chylothorax.

Background: Chylothorax is a treacherous complication after esophagectomy associated with significant morbidity. Early enteral nutrition after esophagectomy is important for recovery but increases the pressure in the lymphatic system owing to the absorption of triglycerides. To lower the incidence of chylothorax after esophagectomy, the use of low fat-containing tube feeding was evaluated as a standard of care after esophagectomy.

[The transthecal digital block].

Anaesthesia of an entire finger is a routinely performed procedure at the General Practice and the emergency room, and by many surgical disciplines. The method according to Oberst is the most-performed procedure to do this. The transthecal digital block is a new method that can be easily learned.

Two-Field Lymphadenectomy During Esophagectomy: The Presence of Thoracic Duct Lymph Nodes.

Background: Resection of the thoracic duct is part of the formal en bloc mediastinal esophagolymphadenectomy for cancer, although with the adaptation of minimally invasive techniques, some centers started to leave the thoracic duct compartment in situ. However, previous studies reported thoracic duct lymph nodes in this compartment that may contain metastasis. The aim of this study was to assess the presence and number of lymph nodes in the fatty tissue surrounding the thoracic duct.

The anatomy of the thoracic duct at the level of the diaphragm: A cadaver study.

Background: Injury and subsequent leakage of unrecognized thoracic duct tributaries during transthoracic esophagectomy may lead to chylothorax. Therefore, we hypothesized that thoracic duct anatomy at the diaphragm is more complex than currently recognized and aimed to provide a detailed description of the anatomy of the thoracic duct at the diaphragm.

Basic Procedures: The thoracic duct and its tributaries were dissected in 7 (2 male and 5 female) embalmed human cadavers.

Anticipation of meals during restricted feeding increases activity in the hypothalamus in rats.

Rats exposed to timed restricted meals develop anticipation of food. They increase their activity levels in the hours preceding food access; this has been described as food-anticipatory activity (FAA). In the present study, we show the involvement of regions of the hypothalamus [arcuate nucleus, dorsomedial hypothalamus (DMH) and lateral hypothalamus] in the early development of FAA in rats exposed to the activity-based anorexia (ABA) model.

Recovery of sensorimotor function after experimental stroke correlates with restoration of resting-state interhemispheric functional connectivity.

Despite the success of functional imaging to map changes in brain activation patterns after stroke, spatiotemporal dynamics of cerebral reorganization in correlation with behavioral recovery remain incompletely characterized. Here, we applied resting-state functional magnetic resonance imaging (rs-fMRI) together with behavioral testing to longitudinally assess functional connectivity within neuronal networks, in relation to changes in associated function after unilateral stroke in rats. Our specific goals were (1) to identify temporal alterations in functional connectivity within the bilateral cortical sensorimotor system and (2) to elucidate the relationship between those alterations and changes in sensorimotor function.
