Periodic Limb Movements during Sleep in Acute Stroke: Prevalence, Severity and Impact on Post-Stroke Recovery.

Background: Periodic Limb Movements during Sleep (PLMS) have been described to be frequently present in stroke patients. We aimed to evaluate the prevalence and severity of PLMS in acute stroke patients and clarify the association between PLMS and coexisting Sleep Disordered Breathing (SDB). Additionally, we focused on identifying variables that could independently predict the presence of PLMS in patients with acute stroke.

Resistance to CDK4/6 inhibition: Mechanisms and strategies to overcome a therapeutic problem in the treatment of hormone receptor-positive metastatic breast cancer.

Selective CDK4/6 inhibitors, such as palbociclib, ribociclib, and abemaciclib, have been approved in combination with hormone therapy for the treatment of patients with HR+, HER2-negative advanced or metastatic breast cancer (mBC). Despite their promising activity, approximately 10 % of patients have de novo resistance, while the rest of them will develop acquired resistance after 24-28 months when used as first-line therapy and after a shorter period when used as second-line therapy. Various mechanisms of resistance to CDK4/6 inhibitors have been described, including cell cycle-related mechanisms, such as RB loss, p16 amplification, CDK6 or CDK4 amplification, and cyclin E-CDK2 amplification.

Impact of change in traffic flow on vehicle non-exhaust PM and PM emissions: A case study of the M25 motorway, UK.

This study quantifies the change in traffic flow on the M25 motorway in the UK due to the COVID-19 outbreak. Moreover, the impact of the change in traffic flow on non-exhaust PM and PM emissions for different categories of vehicle was explored. During the year of the COVID-19 outbreak (March 2020 to February 2021), the total traffic flows of passenger cars (PCs), light goods vehicles (LGVs), heavy goods vehicles (HGVs), and long HGVs on the M25 motorway decreased by 38.

Recurrence-free Survival and Safety of Imatinib in Patients With Gastrointestinal Stromal Tumour (GIST) in Greece.

Aim: The purpose of the Imadje study was to confirm the efficacy and safety of imatinib, following resection of kit-positive gastrointestinal stromal tumour (GIST), in the adjuvant setting in the Greek population.

Patients And Methods: A total of 34 adult patients already receiving imatinib were enrolled. Recurrence-free (RFS) and overall survival, as well as time to treatment failure and safety were assessed.

Devastating epidemics in recent ages Greek populations.

In the recent Greek ages the most devastating epidemics were plague, smallpox, leprosy and cholera. In 1816 plague struck the Ionian and Aegean Islands, mainland Greece, Constantinople and Smyrna. The Venetians ruling the Ionian Islands effectively combated plague in contrast to the Ottomans ruling all other regions.

Immune-related intestinal pseudo-obstruction associated with nivolumab treatment in a lung cancer patient.

Immune checkpoint inhibition therapy using targeted monoclonal antibodies is a new therapeutic approach with significant survival benefit for patients with several cancer types. However, their use can be associated with unique immune-related adverse effects as a consequence of impaired self-tolerance due to loss of T-cell inhibition via a nonselective activation of the immune system. Nivolumab is an anti-PD-1 immune checkpoint inhibitor that was recently developed for cancer immunotherapy with remarkable responses in nonsmall cell lung cancer patients.

Granuloma Mimicking Local Recurrence on PET/CT after Liver Resection of Colorectal Liver Metastasis: A Case Report.

Positron emission tomography-computed tomography (PET/CT) improves the diagnostic interpretation of fluorine-18 fluorodeoxyglucose (18F-FDG ) PET and CT in oncologic patients and has an impact on both diagnostic and therapeutic aspects of patient management. However, false positive findings from the PET/CT imaging should be taken into consideration as they mislead physicians into improper therapeutic actions. We present a 48-year-old female patient with a history of left colectomy for colorectal cancer and subsequent liver metastasectomy.

Comparison of 111In-[DTPA0]Octreotide Versus Non Carrier Added 177Lu- [DOTA0,Tyr3]-Octreotate Efficacy in Patients With GEP-NET Treated Intra-arterially for Liver Metastases.

Aim: In patients with progressive, metastatic neuroendocrine tumors (NET), intra-arterial radionuclide infusions with high activities of In-[DTPA]-octreotide and more recently with non-carrier added (nca) Lu-[DOTA,Tyr]-octreotate have been performed with encouraging results. However, the affinity profiles (IC50) of these radiopeptides for human sst2 receptors are markedly different (In-[DTPA]-octreotide, 22 ± 3.6 nM and nca Lu-[DOTA,Tyr]-octreotate, 1.

A 12-year experience at a tertiary hospital on patients with multiple primary malignant neoplasms.

Purpose: The incidence of multiple primary malignant neoplasms (MPMN) has dramatically increased. The purpose of this retrospective study was to present the 12-year experience at a University Hospital in patients with MPMN and to investigate the role of genetic factors in their pathogenesis.

Methods: The medical records of 7516 cancer patients, treated in our Institution from 2000 to 2012, were reviewed.

Cutaneous Metastatic Adenocarcinoma of the Colon to the Scalp.

Cutaneous metastases from colorectal cancer are relatively uncommon presenting in fewer than 5% of patients but they are very important to recognize as they signify disseminated disease and poor prognosis. We describe a case a 62-year-old patient diagnosed with scalp metastasis during his systemic chemotherapy treatment for a colorectal carcinoma stage IVb who underwent excisional biopsy of the metastatic lesion. The identification of cutaneous metastases from colorectal cancer can radically alter therapeutic plans as they typically indicate a wide spread disease.

Successful treatment with the mTOR inhibitor everolimus in a patient with perivascular epithelioid cell tumor.

Perivascular epithelioid cell tumor (PEComa) is an extremely rare neoplasm that appears to arise most commonly at visceral (especially gastrointestinal and uterine), retroperitoneal, and abdominopelvic sites. Malignant PEComas exist but are very rare. These tumors represent a family of mesenchymal neoplasms, mechanistically linked through activation of the mTOR signaling pathway.

Chromophobe renal cell carcinoma with prolonged response to targeted therapy: a case report.

Introduction: Chromophobe renal cell carcinoma is universally accepted as a distinct subtype of renal cell carcinoma. There are conflicting reports on prognosis, and few data on response to treatment exist. Currently, we do not have any effective treatment for the metastatic disease apart from surgical procedures.

Muscle metastasis from hepatocellular carcinoma.

Background: Hepatocellular carcinoma is the most common primary tumor of the liver. Disease dissemination occurs through hematogenous routes and frequently involves the lungs, bone, adrenal glands, and pancreas. The patterns of the extrahepatic manifestations are diverse.

Expression of c-kit in common benign and malignant breast lesions.

Aims And Background: c-kit (CD117) is a transmembrane tyrosine kinase that acts as a type III receptor for mast cell growth factor. In recent years, the role of c-kit in the development of preinvasive and invasive breast carcinomas has been investigated. The aim of our study was to detect c-kit expression in the entire spectrum of common benign and malignant breast lesions in correlation with a well-studied myoepithelial or stem-cell like marker (p63).

Abscess formation mimicking disease progression, in a patient with metastatic renal cell carcinoma during sunitinib treatment.

Background: Renal cell carcinoma (RCC) represents approximately 3% of all adult cancers and is more common in males. Systemic treatment for RCC has improved following the introduction of tyrosine kinase inhibitors, such as sunitinib. The molecular targets of sunitinib are receptor tyrosine kinases (RTKs).

Breast cancer in association with thyroid disorders.

Purpose: The relationship between breast cancer and thyroid diseases is controversial. Conflicting results have been reported in the literature. The incidence of autoimmune and non-autoimmune thyroid diseases were investigated in patients with breast cancer who had received prior therapy as compared with age-matched control individuals without breast or thyroid disease.

Low-dose capecitabine plus docetaxel as first-line therapy for metastatic breast cancer: phase II results.

The addition of capecitabine to docetaxel significantly improves overall survival in anthracycline-pretreated metastatic breast cancer. We evaluated a low-dose capecitabine-docetaxel regimen as first-line therapy. Patients who had received adjuvant anthracyclines received docetaxel 75 mg/m2 on day 1 and capecitabine 950 mg/m2 twice daily, days 1-14, every 3 weeks until disease progression or unacceptable toxicity.

The role of capecitabine in the management of tumors of the digestive system.

Capecitabine has been developed as a prodrug of FU, with the goal of improving tolerability and intratumor drug concentration through tumor-specific conversion to the active drug. The purpose of this article is to review the available information on capecitabine with respect to clinical efficacy for tumors of the digestive tract, adverse-effect profile, documented drug interactions, dosage and administration, and future directions of ongoing research.
