Intraventricular tuberculomas are rare in the absence of systemic tuberculosis (TB), and the differential diagnosis between tuberculoma and other lesions, such as primary brain tumors, can be difficult. We report an extremely unusual case of solitary fourth-ventricular tuberculoma, which occurred in a 3-year-old female patient, with no indication of TB. This lesion appeared as a primary intraventricular tumor in the fourth ventricle in both clinical and radiological examinations. In this scenario, a surgical treatment option was pursued. Histopathological testing supported the diagnosis of tuberculoma. The patient was subsequently treated with 18 months’ therapy for tuberculous, without adverse events.</p> </abstract>ARTICLE2021-08-20T00:00:00.000+00:00Potential of amentoflavone with antiviral properties in COVID-19 treatmenthttps://sciendo.com/article/10.2478/abm-2021-0020<abstract> <title style='display:none'>Abstract</title> <p>Amentoflavone is one of the flavonoids that are known for their antiviral effects and many of them are predicted to have inhibitory effects against severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome Coronavirus (MERS-CoV) enzymes 3-chymotrypsin-like protease (3CLpro) and papain-like protease (PLpro). Amentoflavone is a biflavonoid found in the herbal extracts of St. John's wort (<italic>Hypericum perforatum</italic>), <italic>Gingko biloba</italic>, <italic>Selaginella tamariscina, Torreya nucifera</italic>, and many other plants. Its pharmacological actions have been listed as antiviral, antibacterial, antioxidant, anti-inflammatory, antidiabetic, antidepressant, and neuroprotective. Molecular docking studies have found that amentoflavone binds strongly to the active site of the main protease (M<sup>pro</sup>) of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). As conventional antiviral medications are met with limited success against coronavirus disease-2019 (COVID-19) and vaccines are one of the only weapons against COVID-19 in the pharmaceutical armamentarium, traditional medicines are being considered for the forefront battle against COVID-19. Clinical studies with <italic>Hypericum</italic> and <italic>Gingko</italic> extract as additional or alternative drugs/supplements are registered. Here we review the potential of amentoflavone, an active agent in both <italic>Hypericum</italic> and <italic>Gingko</italic> extract as an adjunct therapy for COVID-19. Its anti-inflammatory, antioxidant, and sepsis preventive actions could provide protection against the “cytokine storm.” Compared with the herbal extracts, which induce cytochrome P450 (CYP) and uridine 5′-diphospho (UDP)-glucuronosyltransferases (UGT) activity producing a negative herb–drug interaction, amentoflavone is a potent inhibitor of CYP3A4, CYP2C9, and UGT. Further studies into the therapeutic potential of amentoflavone against the coronavirus infection are warranted.</p> </abstract>ARTICLE2021-08-20T00:00:00.000+00:00Clinical characteristics and outcomes of Langerhans cell histiocytosis at a single institution in Thailand: a 20-year retrospective studyhttps://sciendo.com/article/10.2478/abm-2021-0022<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Langerhans cell histiocytosis (LCH) is a rare disease characterized by the various systems involved and clinical manifestations with a wide range of symptoms.</p> </sec> <sec><title style='display:none'>Objectives</title> <p>To describe clinical characteristics, imaging, treatment, and outcomes of pediatric LCH at Phramongkutklao Hospital, Bangkok, Thailand.</p> </sec> <sec><title style='display:none'>Methods</title> <p>We conducted a 20-year retrospective review of the medical records of patients diagnosed with LCH from birth to 21 years old from January 1, 1997, to December 31, 2016.</p> </sec> <sec><title style='display:none'>Results</title> <p>In all, 14 patients with median age of 2.5 years were studied.

In the obese women, significant positive correlations were found between circulating levels of leptin and low-density lipoprotein (LDL)-cholesterol, BMI, and glucose; and ghrelin and HDL-cholesterol. Significant negative correlations were found between circulating levels of leptin and HDL-cholesterol and ghrelin; and ghrelin and leptin, LDL-cholesterol, BMI, and glucose. Multivariate analysis revealed that ghrelin was significantly associated with HDL-cholesterol, LDL-cholesterol, and blood glucose.</p></sec><sec id="j_1905-7415.0902.382_s_009_w2aab3b7b5b1b6b1aab1c17b5Aa"><title style='display:none' id="d1389236e3995_w2aab3b7b5b1b6b1aab1c17b5aAa">Conclusions</title><p>The significant negative correlation between leptin and ghrelin suggests that these two hormones may be antagonistic.
