The study of immunity has become an important area of investigation for researchers in a wide range of areas outside the traditional discipline of immunology. For the last several decades, psychoneuroimmunology (PNI) has strived to identify key interactions among the nervous, endocrine and immune systems and behavior. More recently, the field of ecological immunology (ecoimmunology) has been es...

BACKGROUND/AIMS Protein-energy wasting (PEW) is a well-known risk factor of long-term survival in peritoneal dialysis (PD) patients. Serum albumin is a measure of visceral protein, lean body mass is a measure of somatic protein stores and normalized protein nitrogen appearance is a measure of daily protein intake. A protein nutrition index (PNI) that combined these 3 factors was designed and te...

External urethral sphincter electromyography (EMG) during bladder filling was quantitatively analysed using automatic decomposition electromyography (ADEMG). These include 7 normal volunteers, 7 patients with outlet obstruction, 9 with sphincter dyssynergia, and 7 with pelvic nerve injury (PNI). Recruited number of participated motor unit action potentials (MUPs) at maximum bladder filling was ...

This study determined patterns of sensory signs in complex regional pain syndrome (CRPS) type I and II and peripheral nerve injury (PNI). Patients with upper-limb CRPS-I (n=298), CRPS-II (n=46), and PNI (n=72) were examined with quantitative sensory testing according to the protocol of the German Research Network on Neuropathic Pain. The majority of patients (66%-69%) exhibited a combination of...

Background Desmoplastic neurotropic melanoma (DNM) is a rare, highly malignant, and locally invasive form of cutaneous melanoma with a tendency for perineural invasion (PNI). Methods We report a case of a 61-year-old man presenting with right-sided trigeminal neuralgia and progressive facial paresis due to the PNI of the intracranial trigeminal nerve and the intraparotid facial nerve from DNM. ...

Although penetrating neck injuries (PNIs) represent a small subset of patients presenting to the emergency department (ED), they can result in significant morbidity and mortality. The approach to airway management in PNI varies widely according to clinical presentation and local practice, such that global management statements are lacking. Although rapid sequence intubation (RSI) may be safe in...

AIM To evaluate the prognostic significance of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and prognostic nutritional index (PNI) and other clinicopathological factors in patients undergoing curative resection of colon cancer. METHODS 183 patients with histologically proven colorectal cancer who had undergone potentially curati...

Perineural invasion (PNI) is a pathological feature of many cancers associated with poor outcomes, metastases, and recurrence. In relation to ovarian cancer (OC), there no information about PNI’s role mechanisms. Our study found that patients PNI-positive symptoms had significantly shorter overall survival (OS) time than PNI-negative symptoms. Multivariate analyses demonstrated PNI represented ...

Clinicians caring for patients with brachial plexus and other nerve injuries must possess a clear understanding of the peripheral nervous system's response to trauma. In this article, the authors briefly review peripheral nerve injury (PNI) types, discuss the common injury classification schemes, and describe the dynamic processes of degeneration and reinnervation that characterize the PNI resp...

Peripheral nerve injury (PNI), a common injury in both the civilian and military arenas, is usually associated with high healthcare costs and with patients enduring slow recovery times, diminished quality of life, and potential long-term disability. Patients with PNI typically undergo complex interventions but the factors that govern optimal response are not fully characterized. A fundamental u...
