An impairment of social communication is a core symptom of autism-spectrum disorder (ASD). Affective touch is an important means of social interaction, and C-Tactile (CT) afferents are thought to play a key role in the peripheral detection and encoding of these stimuli. Exploring the neural and behavioral mechanisms for processing CT-optimal touch (~3 cm/s) may therefore provide useful insights into the pathophysiology of ASD. We examined the relationship between touch hedonics (i.e. the subjective pleasantness with which affective touch stimuli are perceived) and neural processing in the posterior superior temporal sulcus (pSTS). This region is less activated to affective touch in individuals with ASD, and, in typically developing individuals (TD), is correlated positively with touch pleasantness. https://www.selleckchem.com/products/tak-875.html TD and ASD participants received brushing stimuli at CT-optimal, and CT-non-optimal speeds during fMRI. Touch pleasantness and intensity ratings were collected, and affective touch awareness, a measure of general touch hedonics was calculated. As expected, slow touch was perceived as more pleasant and less intense than fast touch in both groups, whereas affective touch awareness was moderately higher in TD compared to ASD. There was a strong, positive correlation between right pSTS activation and affective touch awareness in TD, but not in ASD. Our findings suggest that altered neural coupling between right pSTS and touch hedonics in ASD may be associated with social touch avoidance in ASD.BACKGROUND Sepsis is a serious clinical problem that results from the systemic response of the body to infection. Left ventricular (LV) diastolic dysfunction is increasingly appreciated as a contributor to morbidity and mortality in sepsis. Animal models may offer a method of studying diastolic dysfunction while controlling for many potential clinical confounders, such as sepsis duration, premorbid condition, and therapeutic interventions. This study sought to evaluate an endotoxemia (LPS) rodent model of sepsis, with regard to echocardiographic evidence, including tissue Doppler, of LV diastolic dysfunction and histopathology findings. MATERIAL AND METHODS Fourteen male Sprague-Dawley rats were randomly allocated (1 1) to LPS or saline (control). Mean arterial blood pressure (MAP) was measured through cannulation of the carotid artery. After a 30-min stabilization, baseline assessment with echocardiography and blood collection was performed. Rats were administered 0.9% saline or LPS (10 mg/mL). Follow-up echocardiography and blood collection were performed after 2 h. Hearts were removed post-mortem and pathology studied using histology and immunohistochemistry. RESULTS LPS was associated with hypotension (MAP 81.86±31.67 mmHg; 124.29±20.16; p=0.02) and LV impaired relaxation (myocardial early diastolic velocity [e'] 0.06±0.02 m/s; 0.09±0.02; P=0.008). Histopathology and immunohistochemistry demonstrated evidence of interstitial myocarditis (hydropic changes and inflammation). CONCLUSIONS LPS was associated with both diastolic dysfunction (impaired relaxation) and interstitial myocarditis. These features may offer a link between the structural and functional changes that have previously been described separately in clinical sepsis. This may facilitate further studies focused upon the mechanism and potential benefit treatment of sepsis-associated cardiac dysfunction.BACKGROUND Large renal tumors during pregnancy are rare findings (0.07-0.1%). Current guidelines recommend surgical removal. This surgery should be carefully planned in an interdisciplinary team and involves special risks for mother and fetus. This report describes a case of a 27-year-old primigravida woman with a right renal cell carcinoma involving the lower pole of the kidney, which was removed at 30 weeks of gestation by robot-assisted retroperitoneoscopic partial nephrectomy (RARPN). CASE REPORT The patient was referred by the treating obstetrician with a newly diagnosed right lower pole renal mass of 6×4 cm in greatest diameter extending deeply into the parenchyma. No metastasis or enlarged lymph nodes were described in subsequent magnetic resonance tomography. Clinical and laboratory examinations documented a healthy mother and fetus. A right-sided RARPN was advised and planned by an interdisciplinary team of treating physicians (gynecologists, oncologists, and urologists). The surgery was conducted under general anesthesia with an obstetrician on stand-by. Surgery was performed without any complications (operation time 95 min, renal-ischemia time 15 min, and negligible blood loss) and histopathology confirmed the diagnosis of a chromophobe renal cell carcinoma. Further follow-up consultations showed regular wound healing and normal progression of pregnancy, and the patient gave birth to a healthy child at term. Follow-up examinations of the patient were uneventful. CONCLUSIONS This case shows that RARPN can be a safe and effective surgical procedure for partial nephrectomy during pregnancy, where surgery is performed in a specialist center and by an interdisciplinary experienced surgical team. It seems to offer advantages and better risk profile over the laparoscopic approach.BACKGROUND The electroencephalographic (EEG) findings associated with tetrahydrocannabinol (THC) use, particularly in concentrated form, are not well-described, despite the current widespread availability of these products. There is a lack of prior research describing the EEG findings in adolescent cannabis users, and the effects of THC on the seizure threshold have been variably reported. CASE REPORT A 17-year-old girl with no prior history of seizures or known seizure risk factors presented to an Emergency Department with acutely abnormal behavior in the setting of daily vaping of highly concentrated THC marijuana ("wax"). On admission, she had a witnessed generalized tonic-clonic seizure. Urine toxicology was positive for THC, and an extensive evaluation for other etiologies of her encephalopathy was unrevealing. Extended EEG on admission showed mild diffuse background slowing with occasional bifronto-centrally predominant sharp and spike wave discharges. Seven days later, without interim antiseizure medications, a repeat extended EEG showed resolution of the previously seen interictal findings.
