Long-term survival in a patient with Virchow’s lymph node metastasis of cecal cancer

Abstract

The patient was a 53-year-old male with a chief complaint of bloody stool. To treat the cecal colon cancer, right hemicolectomy was performed. Histological examination showed moderately differentiated adenocaricinoma, SE, N3, H0, P0, M0 Stage IIIb by Japanese Classification of the Colorectal Carcinoma. After the operation, the patient received a chemotherapy with 6 cycles of Capecitabine regimen. After 1 year later, computed tomography detected swelling of Virchow's lymph node and tumor in the thyroid gland. By fine-needle aspiration cytology, thyroid gland tumor was diagnosed as papillary cancer and Virchow's lymph node was detected adenocarcinoma which was metastasis of cecal cancer. Total thyroidectomy and cervical lymph node dissection were performed. After the operation, the patient received chemotherapy with 6 cycles of FOLFOX regimen. And the patient had taken UFT/LV for 30 months. Now he has no recurrence and keeps his quality of life high. He has been alive for 80 months since the first operation. Virchow lymph node dissection can be one of the options of treatment of metastasis.

Treatment with lacosamide impedes generalized seizures in a rodent model of cortical dysplasia

Summary

Objective

Epilepsy is a common neurologic disorder resulting in spontaneous, recurrent seizures. About 30–40% of patients are not responsive to pharmacologic therapies. This may be due to the differences between individual patients such as etiology, underlying pathophysiology, and seizure focus, and it highlights the importance of new drug discovery and testing in this field. Our goal was to determine the efficacy of lacosamide (LCM), a drug approved for the treatment of focal seizures, in a model of generalized epilepsy with cortical dysplasia (CD). We sought to compare LCM to levetiracetam (LEV), a drug that is currently used for the treatment of both partial and generalized epilepsy and to test its proficiency.

Methods

Pregnant rats were irradiated to produce pups with malformed cortices in a model of CD, which will be referred to as the "first hit." Adult animals, developed normally (NL) and irradiated (XRT), were surgically implanted with electroencephalography (EEG) electrodes. Baseline EEG was recorded on all rats prior to pretreatments with either LCM, LEV, or placebo (PBO). After 30 min, all rats were injected with a subconvulsive dose of pentylenetetrazole (PTZ), a γ-aminobutyric acid receptor A (GABA_A) antagonist used to provoke generalized seizures as a "second hit."

Results

LCM and LEV were both effective against seizures induced by PTZ. XRT rats had a higher seizure incidence with longer and more severe seizures than NL rats. Seizure duration was decreased with both LCM and LEV in all animals. In XRT rats, there was a significant reduction in acute seizure incidence and severity with both LCM and LEV after PTZ injection.

Significance

Our results suggest that LCM could be used as a potential treatment option for generalized epilepsy with CD as the underlying pathology.

Breast cancer subtype discrimination using standardized 4-IHC and digital image analysis

Abstract

Breast cancer is a heterogeneous disease. Surrogate classification of intrinsic subtypes of invasive carcinomas by combined immunohistochemistry for estrogen receptor (ER), progesterone receptor (PR), HER2, and Ki67 (4-IHC) has increased steadily since the 2011 St Gallen symposium, due to its rapid subtyping of tumors at a reasonable cost. An important step in improving 4-IHC reproducibility and reliability will be to provide reference values from the routine use of standardized 4-IHC followed by image analysis. The aims of the current study were (1) to analyze invasive breast carcinomas using standardized 4-IHC and quantitative image analysis and (2) to compare the results obtained in the classification of biological subtypes using current Ki67 and PR threshold values proposed by different authors to sub-classifying the luminal A-like and the luminal B-like (HER2-negative) subtypes. Five hundred twenty-one tumors were analyzed by standardized immunohistochemistry, with automatic image analysis, and HER2 FISH technique. Positivity for ER was found in 82.7% and for PR in 70.1% of cases. Using the Allred scoring system, hormone receptor results showed a bimodal distribution, particularly for ER. HER2 positivity was found in 15.7% of cases, and the mean Ki67 score was 32.3%. Using the most recently proposed surrogate definitions for the classification of luminal breast cancer subtypes, the percentages of different subtypes that we found were similar to those published with genomic platforms: 40.7% luminal A-like, 32.4% luminal B-like/HER2-negative, 9.8% luminal B-like/HER2-positive, 6.0% HER2-positive, and 11.1% triple negative. Standardized 4-IHC with automatic image analysis constitutes a low-cost method for surrogate definitions of biological subtypes of breast cancer that delivers accurate results in a day.

Cognitive or Cognitive-Motor Executive Function Tasks? Evaluating Verbal Fluency Measures in People with Parkinson’s Disease

Introduction. Executive function deficits are observed in people with Parkinson's disease (PD) from early stages and have great impact on daily living activities. Verbal fluency and oral diadochokinesia involve phonarticulatory coordination, response inhibition, and phonological processing and may also be affected in people with PD. This study aimed to describe the performance of PD patients and an age- and education-matched control group on executive function, verbal fluency, and oral diadochokinesia tests and to investigate possible relationships between them. Methods. Forty people with PD and forty controls were evaluated with Trail Making Test (TMT, executive function) and phonemic/semantic verbal fluency and oral diadochokinesia (/pataka/) tests. Groups were compared by ANOVA and relationships were investigated by Pearson tests. Results. People with PD showed longer times in parts A and B of TMT. They also said fewer words in phonemic/semantic verbal fluency tests and less syllables in the diadochokinesia test. Oral diadochokinesia strongly correlated to parts A and B of TMT and to phonemic verbal fluency. Conclusion. Oral diadochokinesia was correlated to executive function and verbal fluency. The cognitive-motor interaction in verbal fluency and oral diadochokinesia must be considered not to overestimate the cognitive or motor impairments in people with PD.

Low-grade albuminuria is associated with poor memory performance in the nondemented Chinese elderly with type 2 diabetes

Abstract

Recent studies have correlated cognitive function with albuminuria. We investigated the association between low-grade albuminuria and cognitive performance in nondemented elderly with type 2 diabetes in Fuzhou, China. Between January, 2013 and December, 2014, a retrospective study was performed in 815 patients with type 2 diabetes (398 female and 417 male patients), ages ≥60 years, with normal urinary albumin to creatinine ratios (UACR <30 mg/g). Patients were stratified into tertiles based on UACR levels (lowest tertile, UACR <5.8 mg/g; highest tertile, UACR ≥18.1 mg/g). Cognitive function was measured using the Mini Mental State Examination. UACR tertiles correlated directly (p < 0.05) with age, duration of diabetes, systolic blood pressure (SBP), and pulse wave velocity (PWV). Patients in the second and highest tertiles performed significantly worse on memory and language than those in the lowest UACR tertile (p < 0.05). The association between UACR and memory loss was stronger in patients younger than 70 years of age and in those with a history of diabetes for less than 10 years. Low-grade albuminuria is associated with poor memory performance, especially in the youngest old (60–69 years) and in those with shorter duration of diabetes (< 10 years). Type 2 diabetics with urinary albumin excretion in the upper normal range were also at risk for declining memory performance.

Reputation Management and Content Control: An Analysis of Radiation Oncologists’ Digital Identities

The authors identified all Medicare-participating radiation oncologists in the United States and Puerto Rico and developed a customized Google-based search engine. Up tothe top 10 search results for each physician were extracted and categorized. Results for academic and nonacademic radiation oncologists were compared. Most radiation, oncologists lacked self-controlled online content in the first page of Google search results. Strategies for radiation oncologists to improve their digital presence are discussed.
