We report a case of permanent high-frequency hearing loss and tinnitus in a 38-year-old woman following an unrecognised dural puncture during epidural placement. The patient reported subjective unilateral hearing loss and tinnitus, along with a post-dural puncture headache, four hours post-delivery. The patient's headache resolved following two epidural blood patches, however, hearing loss and tinnitus persisted longer than two years. Long-term auditory symptoms following epidural analgesia in labour are very unusual findings.

We conducted a phase I-II study to evaluate Nilotinib (NIL) safety and pharmacokinetics in 22 SR-cGVHD patients; we also evaluated ORR by using in parallel NIH criteria and an exploratory approach, combining objective improvement (OI) without failure criteria (GITMO criteria). Results: 22 patients were enrolled. After dose escalation up to 600 mg/day, MTD was not reached. Main toxicities were asthenia, headache, nausea, pruritus, cramps, and mild anemia. Mean and median plasma concentrations of NIL (C-NIL) were 817 (SD ± 450) and 773 ng/ml. ORR at 6 months, according to 2005 and 2014 NIH and GITMO criteria were 27.8%, 22.2%, and 55.6% respectively; close correspondence has been observed for ORR, according to 2014 NIH criteria, both assessed in a conventional way and assisted by dedicated software (CROSY). At 48 months OS was 75% while FFS, according to NIH and GITMO criteria, was 30 and 25%. In conclusion the safety profile of NIL and long-term outcome makes NIL an attractive option in SR-cGVHD. Exploratory GITMO criteria could represent an alternative tool for easy response evaluation in patients with prevalent skin and lung involvement, but require validation in a larger population; CROSY software showed excellent reliability in capturing ORR according to the 2014 NIH criteria.

Ample evidence suggests that early life stress (ELS) is a high-risk factor for the development of visceral pain disorders, whereas the mechanism underlying neuronal circuit remains elusive. Herein, we employed neonatal colorectal distension (CRD) to induce visceral hypersensitivity in rats. A combination of electrophysiology, pharmacology, behavioral test, molecular biology, chemogenetics and optogenetics confirmed that CRD in neonatal rats could predispose the elevated firing frequency of the parvocellular corticotropin-releasing hormone (CRH) neurons in the paraventricular nucleus of hypothalamus (PVN) in adulthood, with the CRH neurons activated and the frequency of spontaneous inhibitory postsynaptic currents (sIPSC) diminished, both contributing to chronic visceral hypersensitivity. Moreover, following administration of exogenous GABA (300 mM/0.5 μL) and GABA receptor agonist muscimol (3 mM/0.5 μL) in PVN, visceral hyperalgesia was abrogated. In addition, the PVN-projecting GABAergic neurons were mainly distributed in the anterior ventral (AV) region in the bed nucleus of stria terminalis (BNST), and the excitability of these GABAergic neurons was weakened in visceral hypersensitivity. Specific depletion of the GABAergic neurons in AV region precipitated visceral hyperalgesia. Moreover, chemogenetic activation of the PVN-projecting neurons alleviated the visceral hypersensitivity. Photoactivation of PVN-projecting GABAergic neurons abated the visceral hypersensitivity in neonatal-CRD rats, whereas photoinhibition evoked visceral hyperalgesia in naïve rats. Our findings demonstrated that disinhibition of the PVN-projecting GABAergic neurons in AV region contributed to the excitation of CRH neurons, thereby mediating visceral hypersensitivity. Our study might provide a novel insight into the neuronal circuits involved in the ELS-induced visceral hypersensitivity.

Stressors during the fetal and postnatal period affect the growth and developmental trajectories of offspring, causing lasting effects on physiologic regulatory systems. Here, we tested whether reduced uterine artery blood flow in late pregnancy would alter body composition in the offspring, and whether feeding offspring a western diet (WD) would aggravate these programming effects. Pregnant rats underwent bilateral uterine artery ligation (BUAL) or sham surgery on gestational day (GD)18 (term = GD22). At weaning, offspring from each group received either a normal diet (ND) or a WD. BUAL surgery increased fetal loss and caused offspring growth restriction, albeit body weights were no longer different at weaning, suggesting postnatal catch-up growth. BUAL did not affect body weight gain, fat accumulation, or plasma lipid profile in adult male offspring. In contrast, while ND-fed females from BUAL group were smaller and leaner than their sham-littermates, WD consumption resulted in excess weight gain, fat accumulation, and visceral adiposity. Moreover, WD increased plasma triglycerides and cholesterol in the BUAL-treated female offspring without any effect on sham littermates. These results demonstrate that reduced uterine artery blood flow during late pregnancy in rodents can impact body composition in the offspring in a sex-dependent manner, and these effects may be exacerbated by postnatal chronic WD consumption.

The symptoms associated with COVID-19 are mainly characterized by a triad composed of fever, dry cough and dyspnea. However, digestive symptoms have also been reported. At first considered as infrequent, they in fact seem to affect more than half of patients. The symptoms mainly include anorexia, diarrhea, nausea and/or vomiting and abdominal pain. Even though prognosis is associated with lung injury, digestive symptoms seem significantly more frequent in patients presenting with severe COVID-19 infection. Digestive presentations, which may be isolated or which can precede pulmonary symptoms, have indeed been reported, with diarrhea as a leading clinical sign. The main biological abnormalities that can suggest COVID-19 infection at an early stage are lymphopenia, elevated CRP and heightened ASAT transaminases. Thoraco-abdominal scan seems useful as a means of on the one hand ruling out digestive pathology not connected with coronavirus and on the other hand searching for pulmonary images consistent with COVID-19 infection. No data exist on the value of digestive endoscopy in cases of persistent digestive symptoms. Moreover, the endoscopists may themselves be at significant risk of contamination. Fecal-oral transmission of the infection is possible, especially insofar as viral shedding in stools seems frequent and of longer duration than at the ENT level, including in patients with negative throat swab and without digestive symptoms. In some doubtful cases, virologic assessment of stool samples can yield definitive diagnosis. In the event of prolonged viral shedding in stools, a patient's persistent contagiousness is conceivable but not conclusively established. Upcoming serology should enable identification of the patients having been infected by the COVID-19 epidemic, particularly among previously undetected pauci-symptomatic members of a health care staff. Resumption of medico-surgical activity should be the object of a dedicated strategy preceding deconfinement.

Past research in population health trends has shown that injuries form a substantial burden of population health loss. Regular updates to injury burden assessments are critical. We report Global Burden of Disease (GBD) 2017 Study estimates on morbidity and mortality for all injuries.

Anterior shoulder dislocations following an epileptic event are considered rare. An extremely rare case of a 41 year old female suffering from bilateral anterior shoulder dislocation with concomitant greater tuberosities fractures after an epileptic seizure is presented. The patient presented to the out-patient orthopaedic clinic due to persistent pain and restriction of shoulders movement, 4 weeks after an epileptic seizure. Clinical examination and radiological evaluation established the diagnosis of bilateral anterior shoulder dislocation with concomitant greater tuberosities fractures. Closed reduction was performed under general anesthesia. There are 12 such cases in the literature, including the present one. Thirty percent of these cases had a delayed diagnosis. It is of paramount importance to have a high clinical suspicion for myoskeletal injuries and especially for shoulder dislocations following an epileptic episode, even in the absence of a traumatic event.

Knee osteoarthritis is one of the most common causes of chronic pain worldwide, and several animal models have been developedto investigate disease mechanisms and treatments to combat associated morbidities. Here we describe a novel method for assessment of locomotor pain behavior in Yucatan swine. We used monosodium iodoacetate (MIA) to induce osteoarthritis in the hindlimb knee, and then conducted live observation, quantitative gait analysis, and quantitative weight-bearing stance analysis. We used these methods to test the hypothesis that locomotor pain behaviors after osteoarthritis induction would be detected by multiparameter quantitation for at least 12 wk in a novel large animal model of osteoarthritis. MIA-induced knee osteoarthritis produced lameness quantifiable by all measurement techniques, with onset at 2 to 4 wk and persistence until the conclusion of the study at 12 wk. Both live observation and gait analysis of kinetic parameters identified mild and moderate osteoarthritis phenotypes corresponding to a binary dose relationship. Quantitative stance analysis demonstrated the greatest sensitivity, discriminating between mild osteoarthritis states induced by 1.2 and 4.0 mg MIA, with stability of expression for as long as 12 wk. The multiparameter quantitation used in our study allowed rejection of the null hypothesis. This large animal model of quantitative locomotor pain resulting from MIA-induced osteoarthritis may support the assessment of new analgesic strategies for human knee osteoarthritis.

Emerging evidence suggests osteoarthritis (OA) and related symptom burden may increase risk for Alzheimer's disease and related dementias (ADRD). However, longitudinal studies are sparse, and none have examined the potential mediating effects of mood or sleep disorders.

No studies to date have investigated the role of early clinical care in time to recovery from concussion in a pediatric population. The purpose of this study was to investigate the role of clinic presentation timing (≤ 7 days [early] compared to 8-20 days [late] from injury) in concussion assessment performance and risk for prolonged recovery (> 30 days) in pediatric concussion.
