Article Synopsis
  • Intracranial artery stenosis (ICAS) is linked to ischemic stroke, and the RNF213 p.Arg4810Lys genetic variant may play a role in this condition, particularly in patients who are asymptomatic.
  • A study involving 139 patients showed that 25% carried the RNF213 variant, which was associated with higher rates of stenosis progression (25.7%) compared to non-carriers (8.7%) over an average follow-up of 58 months.
  • The findings indicate that the RNF213 p.Arg4810Lys variant is significantly associated with increased risk of stenosis progression, suggesting different underlying mechanisms in vascular health that merit further research.

Background: Intersphincteric resection (ISR) has been increasingly used as the ultimate sphincter-preserving procedure in extremely low rectal cancer. The most critical complication of this technique is anastomotic leakage. The incidence rate of anastomotic leakage after ISR has been reported to range from 5.

Objective: We examined whether androgen receptor splice variant 7 (AR-V7) in circulating tumor cell(CTC)clusters can be used to predict survival in patients with bone metastatic castration resistant-prostate cancer (mCRPC) treated with abiraterone or enzalutamide.

Methods: We retrospectively enrolled 98 patients with CRPC on abiraterone or enzalutamide, and investigated the prognostic value of CTC cluster detection (+ v -) and AR-V7 detection (+ v -) using a CTC cluster detection - based AR-V7 mRNA assay. We examined ≤50% prostate-specific antigen (PSA) responses, PSA progression-free survival (PSA-PFS), clinical and radiological progression-free survival (radiologic PSF), and overall survival (OS).

Article Synopsis
  • The study explored the link between cauda equina involvement in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and increased protein levels in cerebrospinal fluid (CSF).
  • Using magnetic stimulation, researchers measured cauda equina conduction times in 14 CIDP patients and found a significant positive correlation between conduction time and CSF protein levels.
  • The findings suggest that when CSF protein levels are elevated in CIDP patients, it is likely that the spinal nerves, especially those of the cauda equina, are being affected.

Objective: We examined whether epidermal growth factor receptor (EGFR) expression in circulating tumor cells (CTCs) can be used to predict survival in a population of bone-metastatic castration-resistant prostate cancer (mCRPC) patients treated with docetaxel chemotherapy.

Methods: All patients with mCRPC who had experienced treatment failure with androgen-deprivation therapy and had received docetaxel chemotherapy were eligible. CTCs and EGFR expression in CTCs were enumerated with the CellSearch System in whole blood.

Aim: We examined whether Circulating Tumor Cells (CTCs) can be used to predict survival in patients with bone-metastatic castration-resistant-prostate cancer (mCRPC) treated with docetaxel chemotherapy.

Patients And Methods: All patients with mCRPC who had experienced treatment failure with androgen deprivation therapy and had received docetaxel chemotherapy were eligible for study inclusion. CTCs in whole blood were enumerated with the CellSearch System.

Background: Although bleaching treatment using all-trans retinoic acid (RA) and hydroquinone (HQ) improves epidermal melanosis, the application of two medications and the irritant dermatitis induced by RA inconvenience patients. To overcome these problems, we developed a silicone sheet containing RA and HQ.

Objective: To compare the efficacy of a silicone sheet containing RA and HQ with that of conventional bleaching treatment.

Introduction: Our aim was to describe our early experience with laparoendoscopic single-site surgery (LESS) via the retroperitoneal approach for upper urinary tract tumors.

Methods: Since April 2010, 21 patients with upper urinary tract cell carcinoma were treated by our team: 12 patients have undergone LESS nephroureterectomy and 9 have undergone standard retroperitoneal laparoscopic surgery. In our LESS procedure, we employed a bendable grasper in the non-dominant hand and a standard straight laparoscopic instrument in the dominant hand.

Outcomes of alternative (second-line) antiandrogen therapy in 112 patients with relapsing prostate cancer after first-line hormonal therapy were analyzed. A good response (prostate-specific antigen [PSA] decrease 50%) and a partial response (PSA decrease of 0–50%) by switching from bicalutamide (BCL) to flutamide (FLT) and from FLT to BCL were achieved in 35.4% (28/79) and 30.

Purpose: Using the CellSearch System we evaluated whether circulating tumor cells predict survival in patients with hormone refractory prostate cancer.

Materials And Methods: Circulating tumor cells were counted with the CellSearch System in whole blood. This system was developed using epithelial cell adhesion prostate cancer antibody based, immunomagnetic capture and automated staining methodology.

Purpose: We determined whether circulating tumor cells predict prostate specific antigen failure in patients with metastatic prostate cancer before endocrine therapy and compared their prognostic ability with other clinical factors.

Materials And Methods: Circulating tumor cells were enumerated with the CellSearchtrade mark system in whole blood. This system was developed using epithelial cell adhesion molecule antibody based immunomagnetic capture and automated staining methodology.

Purpose: Coxsackie and adenovirus receptor is a high affinity receptor for adenovirus type 5. To our knowledge the expression profile of coxsackie and adenovirus receptor in renal cancer has not been described. We evaluated the expression of coxsackie and adenovirus receptor in human renal cancer specimens and determined whether the histone deacetylase inhibitor FK-228 (Astelas Pharmaceutical, Osaka, Japan) increases the efficiency of adenoviral infections in renal carcinoma cells in vivo and in vitro.

Massive pulmonary embolism (PE) with concomitant intracranial hemorrhage (ICH) has a high mortality rate. Although thrombolytic therapy is generally accepted as emergent treatment for massive PE, the risk of bleeding complications are significant. A 69-year-old woman presented with acute PE 11 days after onset of ICH.

Purpose: After it was shown that a rapidly firing focus in a pulmonary vein (PV) can cause atrial fibrillation, percutaneous endocardial PV isolation using radiofrequency began to be used as a method of treatment. However, this technique is time consuming. It requires fluoroscopy and contrast media to identify the PV, and cardiac tamponade and PV obstruction are major complications.

Since Haïssagere and colleagues reported that a rapid firing focus in or close to the pulmonary veins could be the cause of atrial fibrillation, a transcutaneous catheter technique directed at isolating these foci has been developed. How should patients with nonvalvular atrial fibrillation who require cardiac operation be managed? We developed an epicardial technique that uses cryoablation to isolate the left atrial posterior wall and pulmonary veins and used it to treat a patient. Because cryoablation is achieved epicardially, the technique does not require atriotomy and does not prolong aortic cross-clamp time.

Calcification along the outermost aspect of the aorta usually means atherosclerotic aneurysm. On occasion, however, this peripheral type calcification is seen in chronic aortic dissection and leads to a misdiagnosis. Conventional chest roentgenography and CT of 50 cases of chronic dissection proven by angiography were reviewed.

Mutagenicity of instant coffee and its interaction with dimethylnitrosamine in the micronucleus test.

Mutat Res

November 1987

Department of Environmental Health, Faculty of Health Sciences, University of Kyorin, Japan.

The mutagenicity of instant coffee and its interaction with dimethylnitrosamine (DMN) were examined in mice using the micronucleus test. Although neither a single nor multiple administration of instant coffee by gavage induced a significant rise in micronucleated cells over the dose range tested (100-2500 mg/kg), there was a tendency for the number of micronucleated cells to increase in a dose-related fashion. When coffee was administered with DMN, the difference in the frequency of micronucleated cells was small in comparison to a single treatment with DMN alone, thus indicating a lack of synergism between coffee and DMN.
