Solitary colonic metastasis from primary lung adenocarcinoma first presenting as intestinal obstruction: A case report

Rationale: The brain, liver, adrenal glands, and bone are the most common sites of metastatic disease in patients with lung cancer. Symptomatic gastrointestinal metastases are rare. In the present report, we describe a rare case of a patient with intestinal obstruction due to solitary colonic metastasis from primary lung adenocarcinoma, wherein the intestinal obstruction was the first symptom of lung cancer. Patient concerns: A 74-year-old man was admitted to the emergency room with abdominal pain and vomiting, and abdominal computed tomography (CT) indicated obstruction of the ascending colon due to a huge mass. Diagnosis: The ascending colon cancer was found to be a metastatic adenocarcinoma based on the results of the pathology report. Chest CT and positron emission tomography-CT were performed to identify the cancer origin site. Moreover, immunohistochemical staining of the tissue specimen for thyroid transcription factor 1, cytokeratin 7 (CK7), and CK20 and CT-guided gun biopsy of the lung mass confirmed the presence of an adenocarcinoma that originated from the lung. Intervention: Right hemicolectomy was performed as the primary treatment. Outcomes: The patient recovered without any problems due to the surgery itself. However, malignant pleural effusion deteriorated, and no additional palliative chemotherapy was performed. Lessons: Patients with malignant bowel obstruction along with lung infiltration should be suspected of not only colon cancer with lu...

es DU Abstract Human t-cell lymphotropic virus type 1 (HTLV-1)-associated myelopathy (HAM) is a progressive neurological disease whose diagnosis is defined by clinical manifestations and seropositivity for HTLV-1 infection. Cognitive impairment (CI) is considered to occur after spinal impairment. A 51-year-old HTLV-1-infected man classified as an asymptomatic carrier presented difficulties in listening comprehension and executive memory. He was assessed for central auditory processing (CAP), cognition (event-related auditory evoked potential [P300]), and otoneurological functions (galvanic vestibular-evoked myogen...

Hajnal, J-Donald TournierAbstractProbing microstructure with diffusion magnetic resonance imaging (dMRI) on a scale orders of magnitude below the imaging resolution relies on biophysical modelling of the signal response in the tissue. The vast majority of these biophysical models of diffusion in white matter assume that the measured dMRI signal is the sum of the signals emanating from each of the constituent compartments, each of which exhibits a d...

This study aims, first, to validate a retrospectively-gated implementation of the DENSE method for assessing brain tissue pulsations as a physiological marker, and second, to use the acquired measurements to explore intracranial volume dynamics. We acquired repeated measurements of cerebral volumetric strain in 8 healthy subjects, and internally validated these measurements by comparing them to spinal CSF stroke volumes obtained in the same scan session.Peak volumetric strain was found to be highly repeatable between scan sessions. First/second measured peak volumetric strains were: (6.4 ± 1.7)x10−4/(6.7...

In this report we conclude normal inflammatory markers cannot be used as exclusion criteria for the disease. We also review the body of literature to summarise the key features of the condition to assist clinicians in its diagnosis.

CONCLUSIONS: AI technologies are growing their role in health care; but, up to now, their "real-life" implementation remains limited. However, in the near future, the potential of AI-driven era could change the clinical practice in Urology, improving overall patient outcomes. PMID: 31833725 [PubMed - as supplied by publisher]

CONCLUSIONS: Absolok® clips are a valid alternative to Hem-o-Lok® clips to secure blood vessels at the level of tumor bed and to perform a sliding-clip renorrhaphy in patients who underwent open or robot-assisted partial nephrectomy. PMID: 31833724 [PubMed - as supplied by publisher]

CONCLUSIONS: Our data show high adherence and persistence rates in men on ADT. The overall survival in the super-elderly is not influenced by persistence and/or adherence but rather by co-prescriptions. PMID: 31833723 [PubMed - as supplied by publisher]

CONCLUSIONS: ORP, ePLND and seminal vesicle invasion are independent predictors of the risk of hospital readmission over the long term at a large single tertiary referral center. When surgery is chosen as a primary treatment of PCA, patients should be informed of the risk of hospital readmission and related risk factors. Assessing seminal vesicle invasion by preoperative clinical staging identifies locally advanced disease, which is associated with an increased risk of hospital readmission.

The subjective assessment of the included parameters and the unreliability for off-clamp procedures limited their reproducibility; their role in predicting functional and oncologic outcomes has never...
