In this article, presented as the case of a 43-year-old patient with liver cyst posing the problem of positive diagnosis. The uncharacterizable radiology and the questionable serology have demonstrated the essential role of surgery and histological analysis in the management of this type of lesion. This case raises questions that patients and clinicians are often faced with in a hydatid disease endemic country. Through this article, we aim to discussed the latest news on diagnostic tools, the natural evolution of the disease, differential diagnoses as well as new treatment options for cystic hepatic lesion.

History suggests that tasteful properties of sugar have been domesticated as far back as 8000 BCE. With origins in New Guinea, the cultivation of sugar quickly spread over centuries of conquest and trade. The product, which quickly integrated into common foods and onto kitchen tables, is sucrose, which is made up of glucose and fructose dimers. While sugar is commonly associated with flavor, there is a myriad of biochemical properties that explain how sugars as biological molecules function in physiological contexts. Substantial research and reviews have been done on the role of glucose in disease. This review aims to describe the role of its isomers, fructose and mannose, in the context of inborn errors of metabolism and other metabolic diseases, such as cancer. While structurally similar, fructose and mannose give rise to very differing biochemical properties and understanding these differences will guide the development of more effective therapies for metabolic disease. We will discuss pathophysiology linked to perturbations in fructose and mannose metabolism, diagnostic tools, and treatment options of the diseases.

Sex hormone-dependent cancers currently contribute to the high number of cancer-related deaths worldwide. The study and elucidation of the molecular mechanisms underlying the progression of these tumors was a double-edged sword, leading to the expansion and development of new treatment options, with the cost of triggering more aggressive, therapy resistant relapses. The interaction of androgen, estrogen and progesterone hormones with specific receptors (AR, ER, PR) has emerged as a key player in the development and progression of breast, ovarian, prostate and endometrium cancers. Sex hormone-dependent cancers share a common and rather unique carcinogenesis mechanism involving the active role of endogenous and exogenous sex hormones to maintain high mitotic rates and increased cell proliferation thus increasing the probability of aberrant gene occurrence and accumulation highly correlated with abnormal cell division and the occurrence of malignant phenotypes. Cancer related hormone therapy has evolved, currently being associated with the blockade of other signaling pathways often associated with carcinogenesis and tumor progression in cancers, with promising results. However, despite the established developments, there are still several shortcomings to be addressed. Triterpenes are natural occurring secondary metabolites biosynthesized by various pathways starting from squalene cyclization. Due to their versatile therapeutic potential, including the extensively researched antiproliferative effect, these compounds are most definitely a cornerstone in the research and development of new natural/semisynthetic anticancer therapies. The present work thoroughly describes the ongoing research related to the antitumor activity of triterpenes in sex hormone-dependent cancers. Also, the current review highlights both the biological activity of various triterpenoid compounds and their featured mechanisms of action correlated with important chemical structural features.

Integrins contribute to cancer progression and aggressiveness by activating intracellular signal transduction pathways and transducing mechanical tension forces. Remarkably, these adhesion receptors share common signaling networks with receptor tyrosine kinases (RTKs) and support their oncogenic activity, thereby promoting cancer cell proliferation, survival and invasion. During the last decade, preclinical studies have revealed that integrins play an important role in resistance to therapies targeting RTKs and their downstream pathways. A remarkable feature of integrins is their wide-ranging interconnection with RTKs, which helps cancer cells to adapt and better survive therapeutic treatments. In this context, we should consider not only the integrins expressed in cancer cells but also those expressed in stromal cells, since these can mechanically increase the rigidity of the tumor microenvironment and confer resistance to treatment. This review presents some of these mechanisms and outlines new treatment options for improving the efficacy of therapies targeting RTK signaling.

<p class="abstract">Hydatidosis of the psoas is an unusual entity even in countries endemic to hydatid disease. We reported a rare case of hydatid cyst of psoas in a 54 year old man without pathological history. The atypical clinical presentation and the uncharacterizable radiology have demonstrated the essential role of surgery and histological analysis in the management of this type of lesion. The patient underwent a resection of the protruding dome with drainage of the residual cavity  because of the anatomical relationships of this hydatid cyst. Through this case and literature review, we aimed to discuss the diagnostic means, the natural course of the disease, the differential diagnoses as well as the therapeutic options for a hydatid cyst of the psoas.</p>

This chapter looks at the various biologic or target therapies that have been trialled and tested in the last two decades. The treatment of systemic lupus erythematosus (SLE) has progressed over the last few years due to an increased understanding of its pathogenesis; beginning with rituximab, one of the first biologics to be used, the chapter covers therapies up to the present day. Each subsection highlights the relevant mechanism of action which has led to new treatment options: anti-CD20 and 22, anti-B cell activating factors, anti-interferon alpha and anti-T cell activation. A summarized table is available providing a concise summary of the latest biologic therapies in treating SLE. The role of biologic therapies as monotherapy is still being defined, and with time there will be further change in the treatments available and the approach to the treatment of SLE using biologic therapies.

In the quest for new treatment options for depression, attention is being paid to the potential role of psychedelic drugs. Psilocybin is of particular interest given its mechanism of action, its benefits in early trials and its relatively low side effects burden. This viewpoint outlines a number of key issues that remain to be elucidated about its potential use in the clinical environment, including clarification of the profile of people most likely to benefit and those who might experience adverse effects, longer-term outcomes and the role of psychotherapeutic input alongside the drug itself. There are also opportunities to understand better, the neurobiology underpinning its effects.

Epigenetic Regulators

Endometrial cancer is one of the most frequently diagnosed gynecological malignancies worldwide. However, its prognosis in advanced stages is poor, and there are only few available treatment options when it recurs. Epigenetic changes in gene function, such as DNA methylation, histone modification, and non-coding RNA, have been studied for the last two decades. Epigenetic dysregulation is often reported in the development and progression of various cancers. Recently, epigenetic changes in endometrial cancer have also been discussed. In this review, we give the main points of the role of DNA methylation and histone modification in endometrial cancer, the diagnostic tools to determine these modifications, and inhibitors targeting epigenetic regulators that are currently in preclinical studies and clinical trials.

Advances in our knowledge of the pathogenic mechanisms of antiphospholipid syndrome have been achieved in the past few years. Apart from the well-known role of anti-β2-glycoprotein I antibodies, complement, endocrine and genetic factors and a variety of other molecules are now under investigation. These new approaches should lead to novel explanations and potential new treatment options.
