Sarcoidosis is a chronic disorder that can virtually affect any organ system in the body. Histologically, it is characterized by the presence of T lymphocytes, mononuclear phagocytes, and noncaseating granulomas. Most commonly affected are the intrathoracic structures, with 90% of the reported cases involving the lungs. Esophageal involvement in sarcoidosis is extremely rare. Dysphagia is the most common presentation in these patients and can be attributed to various mechanisms such as direct esophageal wall infiltration, extrinsic compression, cranial neuropathy, and brainstem involvement. A thorough online literature review revealed only 23 reported cases of esophageal involvement in sarcoidosis. This paper reviews these reported cases in detail along with newer diagnostic and treatment options, including direction of future therapy.

Leishmaniasis is a vector-borne disease in humans. Simple intracellular parasites cause the disease. Risk factors: socio-economic conditions, poverty. The disease is associated with malnutrition, with population displacement, with poor housing conditions, with a weak immune system, poor sanitary conditions, and lack of waste disposal. Up to 1 million new infections and up to 65,000 deaths from this disease occur annually. About 95% of cases of skin form disease occur in the countries of the American continent. Leishmaniasis occurs in Uzbekistan and Turkmenistan. The carriers of this disease are female mosquitoes. In the mosquito, parasites are in flagellate form. The natural reservoirs of Leishmania can be around 70 species of animals and humans. Infection occurs through mosquito saliva. After a bite, the parasite invades human mononuclear phagocytes. There may be infection of a person in contact with ulcers and other types of damage. Veterinarians have noted a dramatically increasing number of cases of disease in domestic animals. The following forms are clinically distinguished: cutaneous, mucocutaneous, diffuse cutaneous and visceral forms of leishmaniasis. After the disease develops, a stable immunity to this particular type of leishmaniasis develops. Cutaneous leishmaniasis is the most common form. Ulcers form in open areas of the body. Typical places of localization: face, ears, knees, elbows. Some nodules may have a warty surface or resemble xanthomas, keloids. After healing of these ulcers, scars remain for life. The nasopharynx, oral cavity, or nasal mucosa can be affected without destroying the nasal septum. For cutaneous leishmaniasis, the formation of an infectious granuloma is also characteristic. Treatment of cutaneous leishmaniasis can be local or systemic, depending on the damage and pathogen. Local treatment is suitable for minor and uncomplicated lesions. Local treatment options: heat therapy, cryotherapy. Systemic therapy is used in patients with multiple extensive rashes. Patient K. turned to the maxillofacial department. The patient came home to Ukraine for the purpose of diagnosis and treatment. The patient works in Poland at a construction site. According to the patient, several courses of treatment. The treatment had no result. The pharmacotherapy of our Polish colleagues is not known to us. Clinically: superficial skin lesions on the face. On the face are three ulcers of different sizes. Two ulcers on the cheeks and one on the nose. Palpation of the edges of the ulcers is very painful. Diagnostic search for the etiology of this process. Consultation of a rheumatologist  ̶ the goal of eliminating Wegener's disease, rheumatological diseases. Hematologist consultation  ̶ exclude hematology. Infectionist consultation  ̶ rule out parasitic diseases. Laboratory examination: biochemical blood test, immunogram, rheumatic tests. CT scan of the abdomen. Consultation of a parasitologist. The diagnosis was not in doubt.The patient refused examination and treatment in the infectious diseases hospital. The further fate of this patient is not known to us. We want to draw the attention of doctors to the need for a thorough history taking. An epidemiological history is crucial in such cases. Treatment of leishmaniasis is long and toxic. No method of treatment gives 100% of the result. The choice of treatment method will depend on the type of pathogen and the geographical location of the infection.This disease can be brought by tourists, students from relevant countries of the world to Ukraine.

Neuroendocrine neoplasias (NENs) are a heterogeneous group of rare tumors scattered throughout the body. Surgery, locoregional or ablative therapies as well as maintenance treatments are applied in well-differentiated, low-grade NENs, whereas cytotoxic chemotherapy is usually applied in high-grade neuroendocrine carcinomas. However, treatment options for patients with advanced or metastatic NENs are limited. Immunotherapy has provided new treatment approaches for many cancer types, including neuroendocrine tumors, but predictive biomarkers of immune checkpoint inhibitors (ICIs) in the treatment of NENs have not been fully reported. By reviewing the literature and international congress abstracts, we summarize the current knowledge of ICIs, potential predicative biomarkers in the treatment of NENs, implications and efficacy of ICIs as well as biomarkers for NENs of gastroenteropancreatic system, lung NENs and Merkel cell carcinoma in clinical practice.

Since the last decade, the polymer-drug conjugate (PDC) approach has emerged as one of the most promising drug-delivery technologies owing to several benefits like circumventing premature drug release, offering controlled and targeted drug delivery, improving the stability, safety, and kinetics of conjugated drugs, and so forth. In recent years, PDC technology has advanced with the objective to further enhance the treatment outcomes by integrating nanotechnology and multifunctional characteristics into these systems. One such development is the ability of PDCs to act as theranostic agents, permitting simultaneous diagnosis and treatment options. Theranostic nanocarriers offer the opportunity to track the distribution of PDCs within the body and help to localize the diseased site. This characteristic is of particular interest, especially among those therapeutic approaches where external stimuli are supposed to be applied for abrupt drug release at the target site for localized delivery to avoid systemic side effects (e.g., Visudyne®). Thus, with the help of this review article, we are presenting the most recent updates in the domain of PDCs as nanotheranostic agents. Different methodologies utilized to design PDCs along with imaging characteristics and their applicability in a wide range of diseases, have been summarized in this article.

Background: Acne grading is an essential component in establishing treatment options, but little is known on how neck acne should be incorporated into grading scales. Objective: Our objective was to explore the prevalence of neck acne and determine if its own severity category on an acne global grading scale was warranted. Methods: Acne severity was assessed in 6 categories: face, chest, back, anterior upper (AUN), anterior lower neck (ALN), and posterior neck (PN). Results: The overall prevalence of neck acne was 49%. Of these, 44% had AUN acne, 18.5% had ALN acne, and 19.8% had PN acne. AUN and facial acne had a significant correlation ( r = 0.37, P < .05). No correlation was seen amongst other areas. Males presented with a significantly higher severity of AUN (mean [SD], 1.37 [1.09]) than females (mean [SD], 0.52 [0.91]), on average. Conclusions: While neck acne has proven to be common amongst those with acne on other areas of the body, facial acne can be used as a proxy for classification, as neck severity is usually milder.

Solid tumour accounts for 90% of all cancers. The current treatment approach for most solid tumours is surgery, however it is limited to early stage tumours. Other treatment options such as chemotherapy and radiotherapy are non-selective, thus causing damage to both healthy and cancerous tissue. Past research has focused on understanding tumour cells themselves, and conventional wisdom has aimed at targeting these cells directly. Recent research has shifted towards understanding the tumour microenvironment and it’s differences from that of healthy cells/tissues in the body and then to exploit these differences for treatmeat of the tumour. One such approach is utilizing anaerobic bacteria. Several strains of bacteria have been shown to selectively colonize in solid tumours, making them valuable tools for selective tumour targeting and destruction. Amongst them, the anaerobicClostridiumhas shown great potential in penetration and colonization of the hypoxic and necrotic areas of the tumour microenvironment, causing significant oncolysis as well as enabling the delivery of therapeutics directly to the tumourin situ. Various strategies utilizingClostridiumare currently being investigated, and represent a novel area of emerging cancer therapy. This review provides an update review of tumour microenvironment as well as summary of the progresses and current status of Clostridial spore-based cancer therapies.

How the main components in systemic sclerosis—namely autoimmunity, vasculopathy, and fibrosis—fit together is still not sufficiently clear. However, vascular treatment options are well established, the body of evidence for the efficacy of immunomodulatory approaches is increasing, and now at least one hopeful substance that may directly interfere with fibrosis is being tested. Although we still wait for important breakthroughs, there is grounds for hope that better therapeutic options will be available in the near future.

Background Rates of sexually transmissible infections (STIs) have increased over recent years among gay men and other men who have sex with men (MSM) in England and Wales. HIV diagnoses remain high in this group and men with diagnosed HIV are disproportionally affected by STIs. MSM are therefore a priority for health promotion efforts to reduce STIs. Understanding awareness of and attitudes towards STIs is essential in developing health promotion interventions to reduce prevalence. Methods: Eight focus group discussions (FGDs) with a total of 61 MSM in four English cities included a ranking exercise to gauge how ‘scary’ participants thought 11 STIs are. The exercise sought insights into participants’ awareness of, knowledge about and attitudes towards STIs and blood-borne viruses (BBVs). FGDs were audio-recorded, transcribed and data analysed thematically. Results: All groups ranked HIV and Hepatitis C virus (HCV) as the scariest infections, and the majority ranked syphilis and herpes as highly scary. Scabies was ranked as the least scary by most groups. Rankings were dependent on how well informed participants felt about an infection, its transmission mechanisms, health affect and the availability of vaccines and treatment. Personal experience or that of friends influenced perceptions of particular infections, as did their prevalence, treatment options, visibility of symptoms and whether an STI could be cleared from the body. Conclusions: The study findings suggest that, although some MSM are well informed, there is widespread lack of knowledge about the prevalence, modes of transmission, health implications and treatment regimens of particular STIs.

The transient receptor potential (TRP) cation channel superfamily comprises more than 50 channels that play crucial roles in physiological processes. TRP channels are responsive to several exogenous and endogenous biomolecules, with aldehydes emerging as a TRP channel trigger contributing to a cellular cascade that can lead to disease pathophysiology. The body is not only exposed to exogenous aldehydes via tobacco products or alcoholic beverages, but also to endogenous aldehydes triggered by lipid peroxidation. In response to lipid peroxidation from inflammation or organ injury, polyunsaturated fatty acids undergo lipid peroxidation to aldehydes, such as 4-hydroxynonenal. Reactive aldehydes activate TRP channels via aldehyde-induced protein adducts, leading to the release of pro-inflammatory mediators driving the pathophysiology caused by cellular injury, including inflammatory pain and organ reperfusion injury. Recent studies have outlined how aldehyde dehydrogenase 2 protects against aldehyde toxicity through the clearance of toxic aldehydes, indicating that targeting the endogenous aldehyde metabolism may represent a novel treatment strategy. An addition approach can involve targeting specific TRP channel regions to limit the triggering of a cellular cascade induced by aldehydes. In this review, we provide a comprehensive summary of aldehydes, TRP channels, and their interactions, as well as their role in pathological conditions and the different therapeutical treatment options.

Pseudomonas aeruginosa and Staphylococcus aureus are bacteria pathogens that cause a myriad of infections affecting various sites in the body including the eyes, ears, lungs, skin, heart, bones, and blood amongst others. These bacteria can be disseminated via the blood to other parts of the body away from the primary site of infection and consequences vary from mild to severe with death occurring in certain instances. Both bacterial infections can occur individually, as well as in co-infection resulting in even worse outcomes. P. aeruginosa and S. aureus exhibit multidrug resistance against current antibiotic treatment regimens, which accentuates the challenge in managing the infections caused by these bacteria. To prevent the looming era of untreatable bacterial infections, alternative treatment regimens that are cost effective and accessible are needed. To explore novel treatment options, twenty-five organic compounds comprising fatty acids and their derivatives were screened for antibacterial activity in broth microdilution assay to determine the minimum inhibitory concentration and minimum bactericidal concentration against both P. aeruginosa and S. aureus. Five candidates (N–nonanoic acid, butyric acid, heptanoic acid, palmitoleic acid, and isopropyl myristate) were effective against P. aeruginosa. Seven candidates (N–nonanoic acid, palmitoleic acid, tridecanoic acid, sebaic acid, undecanoic acid, monolaurin, and monocaprin) were effective against S. aureus. Candidates such as N–nonanoic acid and palmitoleic acid were effective against both P. aeruginosa and S. aureus, demonstrating that the same fatty acids show potential to be used against both Gram negative and Gram positive bacterial infections.

Background: Cosmetic treatment was closely associated with beauty seekers' psychological well-being. Patients who seek cosmetic surgery often show anxiety. Nevertheless, not much is known regarding how personality traits relate to the selection of body parts that receive cosmetic treatment.Aims: This study aims to investigate the correlation between personality traits and various selection sites for cosmetic treatment via Eysenck Personality Questionnaire (EPQ).Methods: A cross-sectional approach was adopted to randomly recruited patients from a general hospital planning to undergo cosmetic treatments. All respondents completed the EPQ and provided their demographic information. The EPQ involves four scales: the extraversion (E), neuroticism (N), psychoticism (P), and lying scales (L). Psychological scales were evaluated to verify that people who selected different body sites for cosmetic intervention possessed different personality portraits.Results: A total of 426 patients with an average age of 32.14 ± 8.06 were enrolled. Among them, 384 were females, accounting for more than 90% of patients. Five treatment sites were analyzed, including the body, eye, face contour, nose, and skin. Comparatively, patients with neuroticism were more likely to undergo and demand rhinoplasty (OR 1.15, 95% CI 1.07–1.24, P &lt; 0.001). Face contour treatment was commonly associated with extraversion (OR 1.05, 95% CI 1.00–1.11, P = 0.044), psychoticism (OR 1.13, CI 1.03–1.25, P = 0.013), and neuroticism (OR 1.05, CI 1.01–1.10, P = 0.019).Conclusions: This novel study attempted to determine the personality profiles of beauty seekers. The corresponding assessments may provide references for clinical treatment options and enhance postoperative satisfaction for both practitioners and patients.
