Oleoma treated with oral colchicine: Report of two cases and review of the literature

Colchicine in Athero-Thrombosis: Molecular Mechanisms and Clinical Evidence

Several lines of evidence have clearly indicated that inflammation plays a pivotal role in the development of atherosclerosis and of its thrombotic complications such as acute coronary syndromes or ischemic stroke. Thus, it has been postulated that the use of anti-inflammatory agents might be extremely useful to improve cardiovascular outcome. Recently, increasing attention has been reserved to one of the oldest plant-derived drugs still in use in clinical practice, colchicine that has been used as drug to treat inflammatory diseases such gout or Mediterranean fever. To date, current guidelines of the European Society of Cardiology have included colchicine as first line choice for treatment of acute and recurrent pericarditis. Moreover, several studies have investigated its role in the clinical scenarios of cardiovascular disease including chronic and acute coronary syndromes with promising results. In this review, starting from a description of the mechanism(s) involved behind its anti-inflammatory effects, we give an overview on its potential effects in atherothrombosis and finally present an updated overview of clinical evidence on the role of this drug in cardiovascular disease.

Colchicine: A potential therapeutic tool against COVID-19. Experience of 5 patients

COVID-19 is a newly emerged disease that has become a global public health challenge. Due to a lack of knowledge about the virus, a significant number of potential targets for using a particular drug have been proposed. Five cases with a clinical history of biopolymers in the gluteal region that developed iatrogenic allogenosis (IA) are presented here. The 5 cases were put under colchicine treatment for IA crisis and had non-specific symptoms (headache, cough without dyspnea, and arthralgias) with a positive SARS-CoV-2 test. Their close contacts had mild to severe symptoms and three of them died. In the SARS-CoV-2 infection different inflammatory pathways are altered where colchicine reduces cytokine levels as well as the activation of macrophages, neutrophils, and the inflammasome. The possible mechanisms that colchicine may use to prevent acute respiratory distress syndrome (ARDS) in patients with COVID-19 infection are also reviewed in this article.

ASIA syndrome symptoms induced by gluteal biopolymer injections: Case-series and narrative review

Background

The number of plastic surgery procedures have been rising in the last few years. The morbi-mortality due to illegal use of biopolymers is a public health problem. One of the clinical consequences, foreign body modelling reaction, may be a precursor of ASIA (Autoimmune/Inflammatory disease induced by adjuvants) syndrome.The objective of this article is to present a case-series study of patients who developed ASIA syndrome following gluteal injection with biopolymers and emphasize the importance of toxic exposure in triggering autoimmune responses. A surgical technique used on some of the patients in the study is described.

Methods

A group of thirteen patients, diagnosed with foreign body modelling reaction, who developed ASIA syndrome confirmed by approved criteria was followed between May 2016 and May 2018. The "Butterfly Wings Technique," a new surgical procedure for patients who have medium to severe compromise, was used on five of them.A narrative literature review was done to look for subjects with ASIA syndrome and gluteal biopolymer infiltration.

Results

All the patients in the present case-series with foreign body modelling reaction developed ASIA syndrome. Some of them had a background of familial autoimmunity. Five of the patients were surgically treated and saw a clinical improvement after the extraction of the biopolymer with the proposed technique.The narrative literature review identified 7 articles related to the disease through the database search.

Conclusions

We suggest that foreign body modelling reaction should be considered a precursor to ASIA syndrome. New research projects will be needed in the future to evaluate the factors that determine when ASIA syndrome is triggered in a patient with this reaction.

An uncommon lymphoma mimic: lipogranulomas

A lipogranuloma is a complication of injecting exogenous oily composites, forming a nodule composed of foreign body histiocytes. These may be seen in the setting of use of anabolic steroids. We present a case of a 52-year-old male with rapidly growing intramuscular masses with accompanying lymphadenopathy and constitutional symptoms. A diagnosis of lymphoma was initially made in view of the multifocal nature of his disease. CT and PET/CT scans were used to profile the extent of disease. However, US-guided biopsy samples demonstrated acute-on-chronic fibro-inflammatory connective tissue, but no evidence of malignancy. A follow-up CT scan showed resolution of most of these masses. Subsequently, a history of self-injected anabolic steroids was obtained. Familiarity of imaging characteristics of lipogranuloma may be helpful in avoiding the pitfall of misdiagnosis in this clinical setting.
