We report a case of advanced human immunodeficiency virus (HIV) infection with multiple opportunistic infections (Pneumocystis carinii pneumonia, cryptosporidiosis, oesophagal candidiasis and cytomegalovirus infection). H3B-120 purchase The patient was presumed to be adherent on antiretroviral therapy (ART) and was initiated on respective treatments for the opportunistic infections but continued to deteriorate. On further reviewing, he was found to be poorly adherent to ART and was advised enhanced adherence counselling after which his condition improved. We report this case to emphasize the importance of adherence to ART medications in the management of patients with HIV.Factor XII (FXII) plays a pivotal role in hemostasis, inflammation and complement system. Its deficiency is usually an incidental finding in an otherwise asymptomatic patient who is identified during his/her routine preoperative blood work. This study aimed in evaluating the clinical course of the surgical patients having FXII deficiency. Information regarding demographics, laboratory tests and management of patients was obtained through medical chart and in-house integrated laboratory management system whereas the medical literature was searched through PubMed®. During the study period, two patients were consulted for FXII deficiency prior to the various surgical procedures. Both patients had uneventful surgeries without any thrombotic events while hemorrhage observed in one patient was secondary to obstetric complications. With the limited evidence today, it is concluded that patients having FXII deficiency are not at increased risk of bleeding, thrombosis or infections during surgery, but a personalized approach is needed for planning an appropriate perioperative management.An anaerobic facultative Gram-stain positive bacterium was isolated from human gut microbiota. Strain Marseille-P5551T was considered to be a new genus within the phylum Firmicutes, as it exhibits a 91.87% similarity level with Faecalicatena orotica (NR_117129.1), the phylogenetically closest related species. The draft genome size of strain Marseille-P5551T is 4 142 938 bp with 44.4% of G + C content. We hereby suggest the creation of Luxibacter massiliensis gen. nov., sp. nov., as a new bacterial genus.Recent Acinetobacter baumannii clinical isolates in a teaching hospital in Myanmar comprised three major sequence types (ST2, ST16 and ST23) and two sporadic STs, showing a high resistance rate to carbapenem associated with blaOXA-23 . The NDM-1 encoding gene was identified in only one isolate exhibiting novel ST1407 (a triple-locus variant of ST16).Complete lung collapse associated with sarcoidosis is exceedingly rare. Although lymphoma should be ruled out when patients with mediastinal lymphadenopathy develop lung collapse, sarcoidosis should be considered in the differential, especially when associated with fibrosing mediastinitis.Abnormal anastomosis of peripheral pulmonary arteries is rare and resembles a pulmonary arteriovenous fistula; thus, when the inflow or outflow route cannot be clearly identified in a suspected pulmonary arteriovenous fistula, the possibility of peripheral pulmonary artery anastomosis should be considered. However, the final diagnosis requires a catheterization study.Chest digital dynamic radiography (DDR) is a novel method for evaluating pulmonary perfusion and ventilation. It could depict ventilation-perfusion mismatch in a pulmonary artery sarcoma with severe stenosis in the right pulmonary artery. This report is the first demonstration of ventilation-perfusion mismatch in a malignant neoplasm using DDR.Invasive mucinous adenocarcinoma (IMA), which is a relatively rare lung adenocarcinoma, is considered a high-grade subtype and is associated with a poor prognosis. IMA is difficult to diagnose by computed tomography because it requires differentiation from inflammatory diseases, such as atelectasis, infectious pneumonia, and organizing pneumonia. Thus far, no reports of radial endobronchial ultrasonography (EBUS) findings in IMA have been published. This article presents a case of IMA with a characteristic shadow, snowball-like appearance on radial EBUS in a 67-year-old Japanese man.Mycobacterium avium complex (MAC)-infected lung bulla was a rare type of pulmonary non-tuberculous mycobacterial (NTM) infection. A 29-year-old man with a history of tetralogy of Fallot was admitted to our hospital because of a high fever and left chest pain. Chest computed tomography showed two bullae with intrabullous fluid in both the lower lobes and centrilobular small nodular shadow in the right upper lobe and the left lower lobe. Culture of bronchoscopic washing specimen from the right upper lobe bronchus and left lower lobe one and purulent fluid drained from the bulla in the left lower lobe revealed Mycobacterium intracellulare. Percutaneous drainage from the left bulla and anti-NTM treatment were performed. Afterwards, symptoms improved and two intrabullous fluid disappeared. Therefore, a diagnosis of multiple infected lung bullae associated with M. intracellulare was made. This is the first documented case of multiple infected lung bullae associated with MAC.Cytokine release syndrome (CRS) is known to be associated with severe coronavirus disease 2019 (COVID-19). Multiple anti-inflammatory therapies such as tocilizumab, corticosteroids, intravenous immunoglobulin (IVIG), and haemoadsorption or haemoperfusion have been used to combat this life-threatening condition. However, immunocompromised hosts are often omitted from research studies, and knowledge on the clinical efficacy of these therapies in immunocompromised patients is therefore limited. We report two cases of immunocompromised patients with severe COVID-19-related CRS requiring mechanical ventilation who were treated with multimodality treatment consisting of tocilizumab, IVIG, and haemoperfusion. Within 48 h, both patients showed clinical improvement with PaO2FiO2 ratio and haemodynamic stability. Both survived to discharge. There were no adverse events following these therapies. In conclusion, combined therapeutic modalities, possibly tailored to individual inflammatory profiles, are promising treatment for severe COVID-19 infection in the immunocompromised host.H3B-120 purchase
