Eaton Lambert Syndrome (ELS) is a disorder of neuromuscular transmission. The defect of neuromuscular transmission is due to decrease in the release of acetylcholine quanta from nerve terminal. This syndrome is frequently associated with bronchogenic carcinoma. The diagnosis is established by electromyography, which characteristically shows 1) low amplitude of evoked compound muscle potential to a single supramaximal stimulus on nerve, 2) significant decremental response at low rates of stimulation 3) marked incremental response at high rates of stimulation. Our patient is 52year old man with dyspnea, coughing and muscle weakness of proximal lower limbs. He has small cell lung cancer and associated with ELS, Superior vena cava syndrome and has metastatic lesion on right supraclavicular lymph node confirmed by pathology. Metastatic mass and SVC syndrome are marked improved following chemotherapy and radiotherapy, however follow up EMG finding does not improved. We are here reporting one case which considered compatible for ELS, with a few elementary reviewed literatures.

The results of studies that evaluated predictive factors for rebleeding in non-variceal upper gastrointestinal bleeding are inconsistent. The aim of this study was to investigate predictive factors for 30-day rebleeding in these patients. A consecutive 312 patients presenting symptoms and signs of gastrointestinal bleeding were enrolled in this prospective, observational study. Clinical and demographic characteristics and endoscopic findings were evaluated for potential factors associated with 30-day rebleeding using logistic regression analysis. Overall, 176 patients were included (male, 80.1%; mean age, 59.7+/-16.0 yr). Rebleeding within 7 and 30 days occurred in 21 (11.9%) and 27 (15.3%) patients, respectively. We found that chronic kidney disease (CKD) (OR, 10.29; 95% CI, 2.84-37.33; P<0.001), tachycardia (pulse>100 beats/min) during the admission (OR, 3.79; 95% CI, 1.25-11.49; P=0.019), and Forrest classes I, IIa, and IIb (OR, 6.14; 95% CI, 1.36-27.66; P=0.018) were significant independent predictive factors for 30-day rebleeding. However, neither Rockall nor Blatchford scores showed statistically significant relationships with 30-day rebleeding in a multivariate analysis. CKD, hemodynamic instability during hospitalization, and an endoscopic high-risk appearance are significantly independent predictors of 30-day rebleeding in patients with non-variceal upper gastrointestinal bleeding. These factors may be useful for clinical management of such patients.

BACKGROUND AND OBJECTIVES: The adequate safety margin in tongue cancer is the most important prognostic factor for local recurrence and survival. This study aimed to evaluate the resection margins using a new technique of tongue resection under the guidance of guide wire under ultrasonography in patients with tongue cancer. SUBJECTS AND METHOD: In this prospective study, 10 patients with presurgical, biopsy-proven, clinical T1 or T2 tongue squamous cell carcinomas underwent resection under the guidance of guide wire inserted using ultrasonography. The data of resection margins of 37 patients who underwent partial glossectomy using the conventional method of palpation were used as control data. RESULTS: The mean safety margins (mm) of the experimental group were 7.59±4.30 (anterior), 8.56±4.69 (posterior), 5.25±3.01 (superior), 5.93±3.66 (inferior), 13.00±13.29 (medial), 5.78±2.64 (deep), and 6.67±3.06 (lateral). There were no differences in the safety margins between the two groups. CONCLUSION: Using guide wire under ultrasonography was not superior to the conventional method for partial glossectomy for having adequate resection margins.

Purpose: We investigated the expression levels of 84 genes in dexamethasone-exposed human lens epithelial cells using polymerase chain reaction (PCR) array analysis. Methods: The viability and motility of lens epithelial cells were examined after treatment with dexamethasone at 0.01, 0.1, and 1 mg/mL; Western blot was used to evaluate the expression levels of fibronectin, α-smooth muscle actin (α-SMA), and E-cadherin. After 24, 48, and 72 hours of dexamethasone treatment at 0.1 mg/mL, the expression levels of 84 growth factors were analyzed using PCR array. Results: Cell viability did not change significantly at dexamethasone levels of 0.01 or 0.1 mg/mL, but decreased markedly at 1 mg/mL; motility increased in a concentration-dependent manner at 0.01 and 0.1 mg/mL. Western blot showed that fibronectin levels increased significantly at all dexamethasone concentrations tested; the α-SMA level increased only at 0.01 mg/mL, and E-cadherin levels decreased significantly at all tested concentrations. PCR showed that the levels of FGF1, FGF2, IL-11, regulators of apoptosis (GDNF, IL-1β, and NRG2), and regulators of cell differentiation (BMP5, FGF1, FGF2, and FGF5) decreased more than twofold, whereas the levels of FGF9 and FGF19 increased more than twofold. Conclusions PCR performed after exposure of lens epithelial cells to dexamethasone may identify the genes involved in the development of steroid-induced cataracts.

Objectives: . We aimed to assess the genetic differences between cases of early-stage tongue cancer that were positive or negative for lymph node metastasis. Methods: . In total, 35 cases of tongue cancer with RNA sequencing data were enrolled in this study. The gene expression profile of the following two groups was compared: N0 group (T stage 1 or 2 with N0 stage) and N+ group (T stage 1 or 2 with N+ stage). Using the R and limma packages in the Bioconductor program, we extracted the differentially expressed genes (DEGs). Gene ontology and pathway enrichment analysis were performed using the Database for Annotation, Visualization and Integration Discovery (DAVID) online tool. Immune cell infiltration was analyzed using the CIBERSORT online program. Immunochemical staining of the cancer tissue was evaluated and The Cancer Genome Atlas (TCGA) data were analyzed to validate the identified DEGs. Results: . No significant differences were found in the infiltration of 22 types of immune cells. Among a total of 51 identified DEGs, 14 genes were significantly upregulated, while 37 genes were significantly downregulated (P<0.01; fold change >2). Pathway analysis revealed significant associations with the arachidonic acid metabolism-related pathway, calcium signaling, and the muscle contraction pathway. The following DEGs were the most significantly different between the two groups: DEFB4A, SPRR2B, DEFB103B, SPRR2G, DEFB4B, and FAM25A. TCGA data showed that DEFB4A and DEFB103B were more highly expressed in the N0 group than in the N+ group, although the difference did not achieve statistical significance. Immunochemical staining of cancer tissue revealed significantly higher expression of defensin in the N0 group. Conclusions . Defensin (DEFB4A, DEFB103B, DEFB4B) may be a novel biomarker for early regional metastasis in T1/2 tongue cancer.

Scapular stabilization is thought to have an important role in improving pain and dysfunction around the neck and shoulders, but evidence of this is lacking. We aim to systematically review the effect of a scapular stabilization exercise (SSE) on pain and dysfunction in patients with nonspecific chronic neck pain (NP). We searched the PubMed, EMBASE, CINAHL, and Cochrane Library databases using the terms (NP [MeSH] OR NP OR cervical pain OR neck ache OR cervicalgia) AND (scapular exercise OR periscapular exercise OR SSEs). We included suitable studies that met the study’s inclusion criteria. Among the 227 studies identified by our search strategy, a total of four (three randomized controlled studies and one prospective study) met the inclusion criteria. The SSE was intense. It included three sets of 10 repetitions. In most of the studies, the exercises were conducted 3 times per week. Most studies reported that the SSE improved pain and dysfunction in patients with nonspecific chronic NP; however, the reviewed articles did not use the same variables for measurement. Additionally, the sample size was small. Although several studies show that SSE might improve NP and dysfunction, the effects of SSE on pain and dysfunction in the neck region remain unclear because the number of studies was small. Further high-quality studies are necessary to identify the detailed effects of SSE in patients with NP.
