Intraocular Hemorrhage

The treatment of pathologies of posterior segment of eye, such as chorioretinitis, uveitis, various neuroretinopathies, vitreous diseases, intraocular hemorrhage, is a rather serious problem due to the difficulties of the adequate delivery of preparations into area of pathological process. One of the most effective ways to deliver drugs to eye tissue in posterior segment are intravitreal injections. The introduction of drugs is carried out directly into vitreous body through a puncture of sclera. This article presents the indications for intravitreal injections, a detailed description of properties of numerous therapeutic agents that can be delivered through intravitreal injections, potential complications of this technique and recommendations for prevention of side effects.

The literature review presents data on existing treatments for psoriasis (P) and psoriatic arthritis (PsA). The relevance of the work is rationale with the difficulties of choosing a particular therapeutic agent by a specialist, depending on the peculiarities of the course of the skin pathological process, damage to the musculoskeletal system, spine and related diseases. Synthetic and targeted drugs are described in a chronological consequences, the review provides accumulated information about their effectiveness in relation to various manifestations of P and PsA, and the safety of their use. In conclusion, current recommendations on the differentiated use of various agents for target therapy based on a comprehensive assessment of the clinical characteristics of patients as well as mechanism of action and side effects of the drugs, are discussed.

BACKGROUND COVID-19 pandemic prompts the study of coronavirus biology and search of putative therapeutic strategies. OBJECTIVE To compare SARS-CoV-2 genome-wide structure and proteins with other coronaviruses, focusing on putative coronavirus-specific or SARS-CoV-2 specific therapeutic designs. METHODS The genome-wide structure of SARS-CoV-2 was compared to that of SARS and other coronaviruses in order to gain insights, doing a literature review through Google searches. RESULTS There are promising therapeutic alternatives. Host cell targets could be modulated to hamper viral replication, but targeting viral proteins directly would be a better therapeutic design, since fewer adverse side effects would be expected. CONCLUSIONS Therapeutic strategies (Figure 1) could include the modulation of host targets (PARPs, kinases) , competition with G-quadruplexes or nucleoside analogs to hamper RDRP. The nicest anti-CoV options include inhibitors of the conserved essential viral proteases and drugs that interfere ribosome slippage at the -1 PRF site.

AbstractAlcohol Use Disorder (AUD) affects a large portion of the population. Unfortunately, efficacious medications to treat the disease are limited. Studies in rodents suggest that mTORC1 plays a crucial role in mechanisms underlying phenotypes such as heavy alcohol intake, habit, and relapse. Thus, mTORC1 inhibitors, which are used in the clinic, are promising therapeutic agents to treat AUD. However, chronic inhibition of mTORC1 in the periphery produces undesirable side effects, which limit their potential use for the treatment of AUD. To overcome these limitations, we designed a binary drug strategy in which male mice were treated with the mTORC1 inhibitor RapaLink-1 together with a small molecule (RapaBlock) to protect mTORC1 activity in the periphery. We show that whereas RapaLink-1 administration blocked mTORC1 activation in the liver, RapaBlock abolished the inhibitory action of Rapalink-1. RapaBlock also prevented the adverse side effects produced by chronic inhibition of mTORC1. Importantly, co-administration of RapaLink-1 and RapaBlock inhibited alcohol-dependent mTORC1 activation in the nucleus accumbens and attenuated alcohol seeking and drinking.

The World

Background. The avalanche-like growth of intravitreal injections in the world has significantly increased interest in the hemodynamics of the processes that occur in the eye when a drug is injected into the vitreous cavity. Every year, the number of intravitreally used drugs and promising areas in which they can be used is growing. This also applies to the creation of new combined medicines and the development of drugs with a long-term therapeutic effect. Aims. Create mathematical model of eyeball to evaluate the movement of the drug substance in it; to estimate the time of the drug's presence in the eye cavity before its complete removal, to characterize the ways of its removal from the eye cavity; to assess the significance of posterior vitreous detachment during the time when the drug is present in the eye cavity; to evaluate the effect on the hydrodynamics of the depth of drug administration. Results. When the drug is administered closer to the center of the eyeball, its residence time increases in comparison with the parietal administration. With a complete posterior detachment of the vitreous body, the time of finding the drug in the eye is prolonged compared to its absence. The obtained results of mathematical modeling of the movement of the drug administered intravitreally cannot be mechanically transferred to the human eye, due to the more complex structure of the latter. Key words: intravitreal injections, vitreous body, mathematic computing.

Urticating Hairs

Tarantulas are large spiders that can defend themselves by shedding urticating hairs (setae). In this paper, we aim to discuss the ocular conditions caused by these setae through a literature review. In total, 25 cases were identified in the PubMed database. Tarantula setae have a barbed structure that enables migration through the globe. They give rise to a spectrum of complaints, causing a granulomatous inflammatory reaction in the compartment they settle. Superficial corneal hairs cause a mild keratitis, while hairs that penetrate Descemet’s membrane can induce an anterior uveitis. Both can be treated with local steroids; when possible, hairs should be debrided. Setae that migrate into the posterior segment can cause a focal vitritis that can be more difficult to treat, sometimes requiring vitrectomy.

Paroxysmal Positional Vertigo

AbstractObjective:We describe a case of benign paroxysmal positional vertigo which occurred after use of a whole-body vibration training plate.Method:Case report and literature review concerning the secondary causes of benign paroxysmal positional vertigo and the physiological effects of whole-body vibration training plates.Results:A 44-year-old woman was referred with classic symptoms of benign paroxysmal positional vertigo following use of a whole-body vibration training plate, a popular form of fitness equipment widely used in sports, rehabilitation and beauty treatments. The condition resolved spontaneously after several days. There have been reports of negative side effects in users of this equipment, such as dizziness, headache and a sensation of imbalance; however, there have been no reported cases involving vertigo. Based on a literature review, this equipment may cause side effects, including vertigo, by generating forces that can increase the original amplitude of internal organs, which may potentially cause labyrinthine trauma or dislocation of otoconia, leading to benign paroxysmal positional vertigo.Conclusions:We suggest that whole-body vibration training plates may potentially induce benign paroxysmal positional vertigo. Manufacturers may need to make users of this equipment aware of this risk, and remind them to use it with caution.

Increasing Demand

AbstractThe paper presents an overview of the use of natural therapeutic agents in combating parasitic diseases. Nowadays there is increasing demand for proven plant therapies, which often are found to be more effective than synthetic pharmaceuticals in chronic diseases. In many cases herbal preparations perfectly supplement the conventional treatment and at the same time do not cause side effects. On the pharmaceutical market there are many drugs of plant origin which have been applied in the treatment of parasitic diseases. However, researchers are still looking for new plants, or specific substances isolated from them, which can be used in therapy. In this paper, drugs of plant origin used in the treatment of amoebiasis, giardiasis, malaria, leishmaniasis, trypanosomiasis and acanthamoebiasis are described.
