A special feature of the case was myocardial damage evident as alterative-productive interstitial myocarditis with a peculiar immune phenotype of cell infiltrate, Cd3+, Cd4+, Cd8-, Cd68+. Furthermore, Cd68-expressing cells were presented by large macrophages with cytoplasmic granulation, which surrounded damaged cardiomyocytes.

[Morphological and Molecular-Biological Changes in the Coronary Arteries after Stenting].

This review addresses morphological changes in coronary arteries following stenting, which result from damage to the vascular wall. These changes include 1) formation of a thrombus in the site of intimal injury; 2) inflammation; 3) proliferation and migration of smooth muscle cells; 4) formation of extracellular matrix. Each of these pathological processes has specific morpho-biological features.

Real-World Experience with Targeted Therapy in BRAF Mutant Advanced Melanoma Patients: Results from a Multicenter Retrospective Observational Study Advanced Melanoma in Russia (Experience) (ADMIRE).

Clinical trials of targeted therapy (TT) and immunotherapy (IT) for highly aggressive advanced melanoma have shown marked improvements in response and survival rates. However, real-world data on treatment patterns and clinical outcomes for patients with advanced BRAF V600 mutant melanoma are ultimately scarce. The study was designed as an observational retrospective chart review study, which included 382 patients with advanced BRAF V600 mutant melanoma, who received TT in a real-world setting and were not involved in clinical trials.

[Renomedullary interstitial cell tumor: review of a rare clinical case].

Autopsy study of a 49-year-old patient demonstrates a rare kidney tumor that had a structure of a mesenchymal renomedullary interstitial tumor (RIO), which had specific characteristics. They include a predominance of the cellular component in the tumor, represented by cells with processes elements (fibroblasts, myofibroblasts), which were surrounded by collagen fibers of interstitium. Apparently, these cells can be involved in the regulation of renin and bicarbonates, the exchange of components of connective tissue (collagen fibers, proteoglycans) and hormones (estrogen, progesterone).

Antiepileptic drugs in pregnancy and hemorrhagic disease of the newborn: an update.

Question: What is the current evidence regarding the association between hemorrhagic disease of the newborn and maternal use of hepatic enzyme-inducing antiepileptic drugs (eg, carbamazepine, phenobarbitone, topiramate)?

Answer: Women with epilepsy who take enzyme-inducing antiepileptic drugs should be advised that there is no adequate evidence to support or refute taking vitamin K in late pregnancy to prevent bleeding complications in a newborn.

Toward improved pregnancy labelling.

Information about the use of a medication in pregnancy is part of overall drug labelling as prepared by the pharmaceutical company and approved by the regulators. It is aimed at assisting clinicians in prescribing, however, very few drugs are labelled for specific indications in pregnancy, since there is rarely information about the use of a drug in this condition. Recently the FDA has drafted new guidelines for the labeling of drugs in pregnancy and breastfeeding, to replace the A,B,C,D,X system that was used for more than 30 years.

Nicotine replacement therapy during pregnancy: recommended or not recommended?

Smoking during pregnancy increases the risks of maternal and fetal complications and adverse neonatal outcomes, and it remains a significant health problem. Although pregnancy is often a strong motivator for smoking cessation, many pregnant women continue to smoke. Effective smoking cessation strategies for use during pregnancy are therefore clearly needed.

Hypoglycemics: pharmacokinetic considerations during pregnancy.

A wide range of physiological and hormonal changes occur during pregnancy. Most begin early in the first trimester and increase by the last trimester. These changes can significantly affect pharmacokinetics and pharmacodynamics of drugs and thus may alter their safety and efficacy.

Risks of statin use during pregnancy: a systematic review.

Although statins have been identified as potential teratogens on the basis of theoretical considerations and small case series, the available evidence is far from conclusive. In fact, epidemiological data collected to date suggest that statins are not major teratogens. The actual risk for an exposed pregnancy seems to be small, if present at all, and does not by itself warrant termination of pregnancy.

[Urokinase and tissue type plasminogen activators and their type-1 inhibitor (PAI-1) in gastric cancer].

The levels of urokinase (uPA) and tissue type (tPA) plasminogen activators and their type 1 inhibitor (PAI-1) were determined by immunoassay in tumor cytosols and samples of histologically unaltered adjacent mucosa in gastric cancer patients. Gastric tumor revealed enhanced uPA and PAI-1 matched by decreased tPA in intact mucosa. The expression of uPA and PAI-1 was particularly was high at the later stages of the disease.
