Iatrogenic tracheal rupture (ITR) represents a life-threatening condition requiring prompt diagnosis, management, and treatment. The management of ITR is challenging, and treatment options depend on tear location, size, injury extent, and the patient's respiratory status. Although this complication has been extensively reported in published literature, the best evidence practice, for the management, requires clarification. In this review, the authors focused on the establishment of a differential diagnosis and the potential mechanism of the injury, the decision-making process, and the therapeutic approaches...

INTRODUCTION: The toxic effects of the ingestion of star fruit (Averrhoa carambola) in chronic kidney disease patients are well described in the literature. Recently, the compound caramboxin has been isolated, explaining the mechanisms of its neurotoxicity. Bilimbi fruit belongs to the family Oxalidaceae, Averrhoa bilimbi species, and exhibits similar biochemical characteristics to star fruit. OBJECTIVE: To report the case of a patient with chronic kidney disease who developed a seizure disorder after the ingestion of bilimbi fruit...

Early detection of HIV infection is the best way to prevent spread of the disease and to improve the efficiency of the antiretroviral therapy. Nucleic acid amplification tests (NAAT) have become the gold-standard for detecting low-concentrations of the virus in blood. However, these methods are technically demanding and cost-prohibitive in developing countries. Immunoassays are more affordable and can be more easily adapted for point-of-care diagnosis. However, the sensitivity so far of these methods has been too low...

Targeted delivery of chemotherapeutic agents to pathology areas can improve drug efficiency and reduce serious side effects on normal regions. However, their treatment mechanism on cells or cell nuclei is still mysterious due to the lack of in situ characterization methods. In this paper, the specific diagnosis and treatment processes of a targeted antitumor agent (doxorubicin, Dox) functionalized aptamer complex (TLS11a-GC-Dox) toward HepG2 cells, a human hepatocellular carcinoma cell line, were tracked in real time by the surface-enhanced Raman scattering (SERS) spectroscopic technique and dark-field imaging with the assistance of gold nanorod-based nuclear targeted probes, which possess remarkable SERS enhancement ability, specific targeting, and excellent biological compatibility...

Colorectal cancer (CRC) is one of the most common cancers worldwide, and microRNAs play important roles in CRC progression. This study aimed to investigate the roles of miR-146a-5p in human CRC and their molecular mechanisms. First, we found that miR-146a-5p was significantly upregulated in CRC tissues and promoted the migration of CRC cells. Then, we identified carboxypeptidase M (CPM) as a direct target of miR-146a-5p, and found that it inhibited the migration and invasion of CRC cells. Our results also showed that CPM expression was positively correlated with overall survival and negatively correlated with recurrence, lymph node invasion, and N stage...

BACKGROUND: Celiac disease is a chronic, small intestinal, immune-mediated enteropathy caused by a permanent intolerance to dietary gluten in genetically predisposed individuals. Clinical studies have found that intestinal cholecystokinin secretion and gallbladder emptying in response to a fatty meal are impaired before celiac patients start the gluten-free diet (GFD). DESIGN: However, it was never really appreciated whether celiac disease is associated with gallstones because there were very few studies investigating the mechanism underlying the impact of celiac disease on the pathogenesis of gallstones...

As a result of recent progress in detection techniques, circulating tumor DNA (ctDNA) and circulating tumor cells (CTC) can now be accurately detected in the blood of most cancer patients. While these new biomarkers can provide a better understanding of key biological mechanisms underlying cancer growth and dissemination, they also open up a wide range of possible clinical applications in medical oncology, radiation oncology and surgical oncology. In this review, we summarize the results obtained with ctDNA and CTC together with their potential future clinical applications in the field of surgical oncology, with particular focus on the perioperative setting of various types of cancer...

Secretory phospholipase A2 group IIA (sPLA2-IIA) is an enzyme that hydrolyzes the sn-2 ester bond in glyceroacyl phospholipids present in lipoproteins and cell membranes. As many immunohistochemical studies reveal that the high expression of sPLA2-IIA in the tumorous tissue or plasma of cancer patients, though low expression in other cases, the enzyme is considered highly relevant with cancer development. Effort has been made to establish the mechanism of how sPLA2-IIA is involved in various cancers in order to understand its pathogenic role and to utilize it as a target for cancer diagnosis and therapy...

Familial hypercholesterolemia (FH) is a disease characterized by a triad: elevated low-density lipoprotein (LDL) cholesterol, tendon xanthomas, and premature coronary heart disease. Thus, it can be considered as a model disease for hypercholesterolemia and atherosclerotic cardiovascular disease (ASCVD). For the diagnosis of hetero-FH, the detection of Achilles tendon xanthomas by palpation or on X-ray is an indispensable diagnostic skill in clinical lipidology. To prevent the under-diagnosis and under-treatment of FH, the diagnostic criteria should be more convenient and user-friendly...

Life expectancy and the number of elderly people are progressively increasing around the world. Together with other pathologies, allergic diseases also show an increasing incidence in geriatric age. This is partly due to the growing emphasis on a more accurate and careful diagnosis of the molecular mechanisms that do not allow to ignore the real pathogenesis of many symptoms until now unknown, and partly to the fact that the allergic people from 20 years ago represent the elderly population now. Moreover, environmental pollution predisposes to the onset of allergic asthma and dermatitis which are the result of internal pathologies more than the expression of allergic manifestations...

Reported is a case of a man aged 55 years who presented with progressive spastic paraparesis. Examination demonstrated multiple cutaneous telangiectases. Subsequent development of upper limb weakness, acute urinary retention and eventual respiratory compromise resulted in the requirement for intensive care unit admission and mechanical ventilation. MRI spine revealed diffuse T2 hyperintensity in the cervical cord with enhancement and cord expansion. Immunomodulatory therapy for a presumed diagnosis of transverse myelitis yielded no response, so a vascular aetiology was suspected...

Cytotoxic lesions of the corpus callosum (CLOCCs) are secondary lesions associated with various entities. CLOCCs have been found in association with drug therapy, malignancy, infection, subarachnoid hemorrhage, metabolic disorders, trauma, and other entities. In all of these conditions, cell-cytokine interactions lead to markedly increased levels of cytokines and extracellular glutamate. Ultimately, this cascade can lead to dysfunction of the callosal neurons and microglia. Cytotoxic edema develops as water becomes trapped in these cells...

REVIEW
Parameswaran Nair, James G Martin, Donald C Cockcroft, Myrna Dolovich, Catherine Lemiere, Louis-Philippe Boulet, Paul M O'Byrne
Airway hyperresponsiveness is a characteristic feature of asthma, and its measurement is an important tool in its diagnosis. With a few caveats, methacholine bronchial provocation by a 2-minute tidal breathing method is highly sensitive; a negative test result (PC20 > 16 mg/mL, PD20 > 400 μg) rules out current asthma with reasonable certainty. A PC20 value of less than 1 mg/mL/PD20 value of less than 25 μg is highly specific (ie, diagnostic) but quite insensitive for asthma. For accurate interpretation of the test results, it is important to control and standardize technical factors that have an impact on nebulizer performance...
