Ultrasound for Postoperative and Iatrogenic Peripheral Nerve Lesions: What Do Radiologists Need to Know?

Iatrogenic nerve injuries are common and require an immediate accurate diagnosis to allow surgical treatment within a short window of opportunity. Targeted investigation using high-resolution ultrasound (US) allows an accurate diagnosis in the acute phase when electrophysiology has a limited role. By identifying the exact site of injury, mechanism, and type of nerve damage, US can help determine the prognosis of the lesion and the need for surgical management.

Proposed amendments regarding the definitions of multidrug-resistant and extensively drug-resistant bacteria.

Introduction: It is fortunate that an international panel of experts proposed definitions for multidrug-resistant (MDR) and extensively drug-resistant (XDR) in the past.

Areas Covered: In our opinion, these definitions need amendments in order to be semantically more accurate.

Expert Opinion: We suggest for the MDR definition to add to 'MDR is defined as non-susceptibility to at least one agent in three or more antimicrobial categories' that this non-susceptibility is at most to the total number of all antimicrobial categories minus two, so that the definition reads: MDR is defined as non-susceptibility to at least one agent in three or more antimicrobial categories and up to (and including) the total number of all antimicrobial categories minus two.

Does gender matter: sex-specific aspects of symptoms, outcome, and therapy of obstructive sleep apnea.

Purpose Of Review: Obstructive sleep apnea (OSA) has historically been considered as a male disease. As a result, female individuals with OSA were often under-diagnosed and under-treated compared with male individuals. However, recent data suggest that several OSA-associated adverse cardiovascular outcomes are more pronounced in women.

Obstructive sleep apnea in pulmonary fibrosis.

Purpose Of Review: In previous years, there was limited research related to the role of sleep in interstitial lung diseases (ILDs). Physicians treating ILD patients tended to focus mainly on the daily disabling symptoms overlooking the possible significant role of coexisting sleep disorders, such as obstructive sleep apnea (OSA). However, recently, there has been a growing interest in OSA in ILDs, as well as OSA effect on sleep, life quality and outcome in these patients with emphasis on idiopathic pulmonary fibrosis (IPF).

The family of 14-3-3 proteins and specifically 14-3-3σ are up-regulated during the development of renal pathologies.

Chronic kidney disease, the end result of most renal and some systemic diseases, is a common condition where renal function is compromised due to fibrosis. During renal fibrosis, calreticulin, a multifunctional chaperone of the endoplasmic reticulum (ER) is up-regulated in tubular epithelial cells (TECs) both in vitro and in vivo. Proteomic analysis of cultured TECs overexpressing calreticulin led to the identification of the family of 14-3-3 proteins as key proteins overexpressed as well.

Sleep as a New Target for Improving Outcomes in Idiopathic Pulmonary Fibrosis.

Idiopathic pulmonary fibrosis (IPF) is the most common type of interstitial pneumonia but remains a disease with a poor outcome. Two drugs, pirfenidone and nintedanib, have shown promising results at stalling disease progression; however, the interplay of sleep disruption or sleep disorders overall and in relation to medication effectiveness remains understudied. In the past, there was limited interest in the role of sleep in patients with IPF.

Multum non multa: airway distensibility by forced oscillations.

Airway distensibility although appears to be unaffected by airway smooth muscle tone probably related to airway remodelling, after bronchodilator treatment is significantly increased in subjects with asthma. We assessed airway distensibity and its first moment derivative in two patients with mild intermittent asthma and normal spirometry. The increase in airway distensibility after bronchodilation measured at the tidal volume range during quiet breathing by forced oscillations was not accompanied by a change in its first moment, while the latter showed a significant increase in a second patient after anti-inflammatory treatment.

Differential monocular vs. binocular pupil responses from melanopsin-based photoreception in patients with anterior ischemic optic neuropathy.

We examined the effect of anterior ischemic optic neuropathy (AION) on the activity of intrinsically photosensitive retinal ganglion cells (ipRGCs) using the pupil as proxy. Eighteen patients with AION (10 unilateral, 8 bilateral) and 29 age-matched control subjects underwent chromatic pupillometry. Red and blue light stimuli increasing in 0.

Obstructive sleep apnea syndrome and cardiovascular disease: The influence of C-reactive protein.

Obstructive sleep apnea syndrome (OSAS) is a common medical condition, associated with atherosclerosis and cardiovascular disease (CVD). The underlying pathophysiologic mechanisms of this association have not been completely understood and may be multifactorial in origin. A number of studies suggest that inflammatory processes have emerged critical in the pathogenesis of CVD in OSAS.

Obstructive sleep apnea should be treated in patients with idiopathic pulmonary fibrosis.

Study Objectives: The most recent idiopathic pulmonary fibrosis (IPF) guidelines include obstructive sleep apnea (OSA) among the IPF-associated comorbidities. Furthermore, they recognize the paucity of studies related to continuous positive airway pressure(CPAP) treatment in this patient group and call for intensive research in this field. Our aim was to assess the effect of CPAP treatment on sleep and overall life quality parameters, morbidity, and mortality in IPF patients with OSA.

Hooking of the soft palate and a large cervical osteophyte: two troubles in the same airway.

We report a case of severe obstructive sleep apnea in a 72-year-old, thin male caused by upper airway obstruction due to an enlarged cervical osteophyte at the C2-C3 level in association with a hooking of the soft palate. This is the first reported case with magnetic resonance imaging recognizing 2 simultaneously existing unusual obstructive causes: the oropharynx (hooking palate) and the hypopharynx (large cervical osteophyte).

Validity of the cohort of Crete in the Seven Countries Study: A time-series study applied to the cancer mortality trend between 1960 and 2011.

We examined whether the Cretan cohort of the Seven Countries Study (SCS) is representative for the entire population in the island using cancer mortality registries. The analysis was carried out on the Cretan cohort of the SCS cancer mortality data and a similar cancer registry for the general population during a 51-year follow-up (1960-2011). Information about the causes of mortality was obtained from official death certificates and classified according to the International Classification of Diseases, 9th Revision (ICD-9).

Medical treatment with thiamine, coenzyme Q, vitamins E and C, and carnitine improved obstructive sleep apnea in an adult case of Leigh disease.

Purpose: The multi-organ involvement of mitochondrial diseases means that patients are likely to be more vulnerable to sleep disturbances. We aimed to assess if early recognition and treatment of obstructive sleep apnea (OSA) in patients with Leigh disease may influence primary disease outcome.

Methods: We describe a case of adult-onset Leigh disease presenting as severe brainstem encephalopathy of subacute onset.

CPAP therapy in patients with idiopathic pulmonary fibrosis and obstructive sleep apnea: does it offer a better quality of life and sleep?

Background: The recent literature shows an increased incidence of obstructive sleep apnea (OSA) in patients with idiopathic pulmonary fibrosis (IPF). On the other hand, there are no published studies related to continuous positive airway pressure (CPAP) treatment in this patient group. Our aim was to assess the effect of CPAP on sleep and overall life quality parameters in IPF patients with OSA and to recognize and overcome possible difficulties in CPAP initiation and acceptance by these patients.
