Hamid Attaran
Methamphetamine is one of the most common abused drugs, so its various effects on different body organs should be familiar to all physicians. Regarding its gastrointestinal sequels, there are few reports of ischemic colitis induced by its vasoconstrictive effects. This is the first report of isolated small intestinal infarction resulting in death following methamphetamine toxicity. A 40-year-old woman with a past history of medical treatment for obesity referred to hospital with severe chest and back pain, perspiration, nausea, agitation, high blood pressure, bradycardia and subsequent lethargy and vasomotor instability...

Although awareness of the Zika virus has existed since the 1950s, only recently has it attracted the interest of the international community. In 2015 and 2016, the virus spread throughout Brazil and suspicions on the possible relation between parallel increases in neurological disorders and the infection arose. By November 2015, this concern had developed into a National Public Health Emergency. On February 1, 2016, WHO formally declared its suspicion that this was a Public Health Emergency of International Concern (PHEIC), and sent a response in accordance with International Health Regulations (2005)...

RATIONALE: Acral lentiginous melanoma (AML) does not exhibit the classic signs of malignant melanoma. ALM is frequently misdiagnosed because of its unusual sites and atypical clinical morphologies, which lead to poor prognosis. PATIENT CONCERNS: A female patient aged 78 years was presented to our center with two ulcers on her right foot. Diabetic foot ulcer was considered as the primary diagnosis. The ulcers failed to improve after 2 weeks' therapy. DIAGNOSES: An incisional biopsy of the lesion revealed malignant melanoma...

Nasal-type natural killer/T-cell (NK/T-cell) lymphoma is a more aggressive sub-group of non-Hodgkin lymphoma, which is more common in Asia. The phosphatase and tensin homolog (PTEN) was originally discovered as a candidate tumor suppressor mutated and lost in various cancers. However, its clinical value and role in NK/T-cell lymphoma remain to be further explored. In the present study, we analyzed PTEN protein expression in 60 cases of human NK/T-cell lymphoma tissues and 40 cases of control nasal mucosa tissues specimens by immunohistochemical analysis...

MOTIVATION: Cancer hallmark annotation is a promising technique that could discover novel knowledge about cancer from the biomedical literature. The automated annotation of cancer hallmarks could reveal relevant cancer transformation processes in the literature or extract the articles that correspond to the cancer hallmark of interest. It acts as a complementary approach that can retrieve knowledge from massive text information, advancing numerous focused studies in cancer research. Nonetheless, the high-dimensional nature of cancer hallmark annotation imposes a unique challenge...

OBJECTIVE: The role of short tandem repeats (STRs) in the control of gene expression among species is being increasingly understood following the identification of several instances in which certain STRs occur identically, or expand differentially, in primates versus nonprimates. These STRs may regulate genes that participate in characteristics that have diverged primates from other species (e.g., brain higher order functions). The CYTH4 gene contains the longest tetranucleotide STR in its core promoter, at 7-repeats, and links to the evolution of human and nonhuman primates...

Malaria, a major global public health problem, is mainly caused by Plasmodium falciparum and Plasmodium vivax, and is responsible for nearly half a million deaths annually. Although P. vivax malaria was not believed to cause severe disease, recent robust studies have proved otherwise. However, the clinical spectrum and pathogenesis of severe vivax malaria and, especially, its respiratory complications remain poorly understood. A systematic search for articles reporting respiratory complications associated with vivax malaria was performed in Lilacs, Cochrane, Scielo, Web of Science, and Medline databases irrespective of publication date...

Mesoamerican nephropathy (MeN), an epidemic of unexplained kidney disease in Central America, affects mostly young, healthy individuals. Its etiology is a mystery that requires urgent investigation. Largely described as a chronic kidney disease (CKD), no acute clinical scenario has been characterized. An understanding of the early disease process could elucidate an etiology and guide treatment and prevention efforts. We sought to document the earliest clinical signs in patients with suspected MeN in a high-risk population in Nicaragua...
