A 74-year-old man presented to our department with progressive dyspnea on exertion over the last year. The patient did not report any other symptoms. ⋯ His history included asymptomatic Waldenström's macroglobulinemia that was diagnosed 18 months before respiratory symptoms. He was not receiving any treatment and was monitored regularly by the hematology department.

Blood products are the current standard for resuscitation of hemorrhagic shock. However, logistical constraints of perishable blood limit availability and prehospital use, meaning alternatives that provide blood-like responses remain an area of active investigation and development. VS-101 is a new PEGylated human hemoglobin-based oxygen carrier that avoids the logistical hurdles of traditional blood transfusion. ⋯ No arteriolar vasoconstriction was observed following VS -101 treatment. In this model of severe ET, VS -101 effectively maintained blood pressure, perfusion, and P ISFo2 with no vasoconstrictive effects. Further elucidation of these beneficial resuscitation effects of VS -101 is warranted to support future clinical trials.

Treatment of cervical pre-cancers involves ablative and excisional therapies, and these have the potential to affect future pregnancy outcomes of women. Understanding the impact of the various treatment modalities on the outcome of pregnancies can motivate the development of interventions to improve pregnancy outcomes in women who had cervical pre-cancer treatment. ⋯ There is an increased odds of second-trimester miscarriage and preterm birth in women treated with LLETZ. A treatment-to-pregnancy interval of ≥ 12 months reduces this odd. Ablative therapies do not increase the odds of miscarriages and preterm births. This information could guide decisions on the choice of method of treatment for cervical pre-cancer in women of childbearing age.

We evaluated the participation of the endocannabinoid system in the paraventricular nucleus of the hypothalamus (PVN) on the cardiovascular, autonomic, and plasma vasopressin (AVP) responses evoked by hemorrhagic shock in rats. For this, the PVN was bilaterally treated with either vehicle, the selective cannabinoid receptor type 1 antagonist AM251, the selective fatty acid amide hydrolase amide enzyme inhibitor URB597, the selective monoacylglycerol-lipase enzyme inhibitor JZL184, or the selective transient receptor potential vanilloid type 1 antagonist capsazepine. We evaluated changes on arterial pressure, heart rate, tail skin temperature (ST), and plasma AVP responses induced by bleeding, which started 10 min after PVN treatment. ⋯ Bilateral microinjection of capsazepine mitigated the fall in blood pressure and ST. None of the PVN treatments altered the increased plasma concentration of AVP and tachycardia induced by hemorrhage. Taken together, present results suggest that endocannabinoid neurotransmission within the PVN plays a prominent role in cardiovascular and autonomic, but not neuroendocrine, responses evoked by hemorrhage.

This study aimed to compare the effect of different obturation techniques with root canal sealers on the residual filling material after retreatment using SEM. ⋯ Residual filling material was observed in all samples, regardless of the root canal sealer or the obturation technique used. There was a significantly lower smear scores in the AH Plus groups as compared to the GFB.
