We present the case of an adult patient with active post-primary pulmonary tuberculosis (TB) and discuss specific morphological and textural aspects found at high-field magnetic resonance imaging (MRI) of the lung. The 42-year-old man, heavy smoker, undertook a routine employment medical examination and was admitted to a referral pulmonology and TB center due to the abnormal findings seen on his chest radiography. The patient presented nonspecific symptoms, bilateral bronchial breath at pulmonary auscultation, inflammatory syndrome on the laboratory blood tests and positive sputum smears for acid-fast bacilli, which together with the typical aspect on the chest radiography lead to a diagnosis of post-primary pulmonary TB and administration of specific medication...

We are in the era cursed with overspecialization. Charles Darwin's foundational Origin of Species, published in 1859 was accessible to the broadly educated individual. Starting with this statement, Peter Bretscher in his new book aims at explaining foundational concepts of immunology to a broad public. His standpoint is that foundational ideas usually can be simply expressed. This book describes first how foundational concepts of immunology have evolved over the last two and a half centuries. The importance of self-nonself discrimination by the immune system is acknowledged and models for immunological tolerance are compared...

Mycobacterium tuberculosis (MTB) is notorious for persisting within host macrophages. Efflux pumps decrease intracellular drug levels, thus fostering persistence of MTB during therapy. Isoniazid (INH) and pyrazinamide (PZA) are substrates of the efflux pump breast cancer resistance protein-1 (BCRP-1), which is inhibited by chloroquine (CQ). In this study, BCRP-1 was found to be expressed on macrophages of human origin and on foamy giant cells at the site of MTB infection. In the current in vitro study, interferon-gamma (IFNγ) increased the expression of BCRP-1 in macrophages derived from the human monocytic leukaemia cell line THP-1...

Mycobacteria harbor two main degradative proteolytic machineries, the caseinolytic protease ClpP1P2 and a proteasome. We recently showed that Bortezomib inhibits ClpP1P2 and exhibits whole cell activity against Mycobacterium tuberculosis. Bortezomib, a dipeptide with a boronic acid warhead, is a human proteasome inhibitor approved for cancer therapy. The boronic acid warhead of the compound has been shown to drive potency against both the human proteasome and ClpP1P2 protease. Selectivity for the bacterial ClpP1P2 protease over the human proteasome is lacking but needs to be achieved to move this new anti-tuberculosis lead forward...

Accurate antigen detection is imperative for clinicians to diagnose disease, assess treatment success, and predict patient prognosis. The most common technique used for the detection of disease-associated biomarkers is the enzyme linked immunosorbent assay (ELISA). In an ELISA, primary antibodies are incubated with biological samples containing the biomarker of interest. Then, detectible secondary antibodies conjugated with horseradish peroxidase (HRP) bind the primary antibodies. Upon addition of a color-changing substrate, the samples provide a colorimetric signal that directly correlates to the targeted biomarker concentration...

RATIONALE: Psoas abscesses generally arise from a contiguous intra-abdominal or pelvic infectious process or hematogenous spreading of bacteria. The serum β-human chorionic gonadotropin has been used to detect normal or ectopic pregnancy. It also can be utilized in following up carcinomas. PATIENT CONCERNS: Here, we reported a case of a 47-year-old woman who presented with a left psoas mass presumptively diagnosed as an abscess secondary to lumbar tuberculosis In addition, the patient had abnormal increase of β-human chorionic gonadotropin...

Warburg effect, as an energy shift from mitochondrial oxidative phosphorylation to aerobic glycolysis, is extensively found in various cancers. Interestingly, increasing researchers show that Warburg effect plays a crucial role in non-tumor diseases. For instance, inhibition of Warburg effect can alleviate pulmonary vascular remodeling in the process of pulmonary hypertension. Interference of Warburg effect improves mitochondrial function and cardiac function in the process of cardiac hypertrophy and heart failure...

INTRODUCTION: Gastrointestinal tuberculosis is common in the developing world especially in the lower socioeconomic groups. In elderly, it may mimic malignancy. CASE PRESENTATION: A 46-year-old female presented with a 6 month history of diffuse pain in abdomen with low grade fever and loss of weight and appetite. Clinically, differential of malignancy of the large bowel was considered. The computerized tomography(CT) scan of the abdomen revealed a diffuse concentric long segmental thickening of terminal ileum, ileo ceacal junction, ascending colon and narrowing of the transverse colonic end of the splenic flexure suggesting an infective etiology...

To investigate the mortality probability, life expectancy of coal workers' pneumoconiosis (CWP), and related factors of life expectancy, a total of 495 patients with CWP were diagnosed and reported from 1963 to 2014 in a state-owned mine in the east of China. The life table method, log rank method, and Cox regression model were used for survival analysis. 95 out of 495 CWP died during this period. The mortality rate was 19.19%. The average life span was 12.1 (0.0-33.2) years and average death age was 57.4 (33...

It is well established in the literature that the incidence of malignancy is higher in transplant patients than in the general population. Risk factors and screening guidelines for transplant patients have been proposed, but are far from standardized. In this case report, we discuss the treatment course of a 73-year-old female with a history of renal tuberculosis, who developed squamous cell carcinoma at the transplant ureterovesical junction 6 years following graft placement. To our knowledge, this is the second reported case in a patient with a history of renal tuberculosis...

Pulmonary meningothelial-like nodules are benign lesions that are often incidentally detected in surgically resected lung tissue. These nodules are usually asymptomatic and single. Rarely, they present as diffuse micronodules similar to the miliary pattern seen in tuberculosis or metastatic cancer. While diffuse meningothelial-like micronodules are usually benign, it is important to include this condition in the differential diagnosis of patients presenting with diffuse micronodules. We present the case of a 74-year-old asymptomatic female referred to the pulmonary clinic for evaluation of incidentally detected diffuse bilateral pulmonary nodules...

As the first line of defense in the human immune system, NK cells play essential roles in prevention of tumorigenesis and viral infection. It is known that NK cells have impaired function in HIV infection; however, it remains unclear why this occurs. IP-10 is a chemokine and inflammatory factor that is associated with such diseases as tuberculosis, hepatitis B virus, and pancreatic cancer. The aim of this study was to evaluate IP-10 levels and CXCR3 expression in NK cells that were affected by HIV and to elucidate whether NK cell function could be affected by IP-10...

Päivi Ylä-Anttila, Eeva-Liisa Eskelinen
Autophagy is an evolutionarily conserved degradation pathway for cells to maintain homeostasis, produce energy, degrade misfolded proteins and damaged organelles, and fight against intracellular pathogens. The process of autophagy entails the isolation of cytoplasmic cargo into double membrane bound autophagosomes that undergo maturation by fusion with endosomes and lysosomes in order to obtain degradation capacity. RAB proteins regulate intracellular vesicle trafficking events including autophagy. RAB24 is an atypical RAB protein that is required for the clearance of late autophagic vacuoles under basal conditions...

Among the dermatological wax collections across Europe, one of the latest created is the collection from Cluj-Napoca University, Romania. The initiator was Professor Coriolan Tataru and the moulage artist employed was Dr. Richard Hoffmann. Between the years 1923 and 1928, around 200 wax moulages were made, all realised after patients hospitalised in the clinic. The majority of cases represent the dermatological infectious pathology of that time: syphilis, cutaneous tuberculosis and mycetomas. Other interesting moulages represent genodermatoses, pelagra, different cutaneous cancers, and atypical aspects of common diseases like psoriasis and eczemas...

The number of elderly patients with psoriasis is increasing in Japan. However, biologic treatment is generally considered to be challenging in elderly patients, due to their increased risk of complications compared with younger patients. Our retrospective study aimed to evaluate the safety profile and efficacy of biologics in senior elderly patients (≥75 years old) with psoriasis. The study involved a cohort of 27 patients aged 75-88 years who were being treated with biologics over a period of more than 1 year...
