Clinics in Shoulder and Elbow 2015;18(3):144-151
BACKGROUND: The consensus is that a bony Bankart lesion shorter than 25% of the length of glenoid does not affect the clinical result; hence, such lesions were often neglected. However, small bony Bankart lesions are associated with various types of capsulolabral lesions. METHODS: A total of 82 patients who had undergone arthroscopic capsulolabral lesion repair surgery for anterior shoulder dislocation were reviewed. The prevalence rates of early and late type of capsulolabral lesions were compared between a group of patients with and a group without small bony Bankart lesions. In addition, the types of accompanying capsulolabral lesion were analyzed according to the type of bony Bankart lesion. Finally, the clinical outcomes were evaluated (active range of motion, American Shoulder and Elbow Surgeons score and Rowe's score). RESULTS: Among the 13 patients who had small bony Bankart lesions, the prevalence rate of early and late type of capsulolabral lesions was 38.5% and 61.5%, respectively. Among the 69 patients without bony Bankart lesion, the prevalence rates of early and late type of capsulolabral lesions were 74% and 26%, respectively. Significantly worse clinical outcome was observed for the group of patients with both small bony Bankart lesions and late type of capsulolabral lesion. CONCLUSIONS: More severe type of small bony Bankart lesion appears to be associated with late type of capsulolabral lesion. The significantly worse clinical outcome for patients with both small bony Bankart lesion and late type of capsulolabral lesion indicates that small bony Bankart lesions cannot always be neglected.

PURPOSE: To evaluate the radial displacement of clinical target volume in the patients with node negative head and neck (H&N) cancer and to quantify the relative positional changes compared to that of normal healthy volunteers. MATERIALS AND METHODS: Three node-negative H&N cancer patients and five healthy volunteers were enrolled in this study. For setup accuracy, neck thermoplastic masks and laser alignment were used in each of the acquired computed tomography (CT) images. Both groups had total three sequential CT images in every two weeks. The lymph node (LN) level of the neck was delineated based on the Radiation Therapy Oncology Group (RTOG) consensus guideline by one physician. We use the second cervical vertebra body as a reference point to match each CT image set. Each of the sequential CT images and delineated neck LN levels were fused with the primary image, then maximal radial displacement was measured at 1.5 cm intervals from skull base (SB) to caudal margin of LN level V, and the volume differences at each node level were quantified. RESULTS: The mean radial displacements were 2.26 (+/-1.03) mm in the control group and 3.05 (+/-1.97) in the H&N cancer patients. There was a statistically significant difference between the groups in terms of the mean radial displacement (p = 0.03). In addition, the mean radial displacement increased with the distance from SB. As for the mean volume differences, there was no statistical significance between the two groups. CONCLUSION: This study suggests that a more generous radial margin should be applied to the lower part of the neck LN for better clinical target coverage and dose delivery.

In order to study the exposure level of silica dust and the effects of silica dust on ventilatory function, respirable dust samples were collected by personal air samplers using NIOSH method 0500 from the selected foundry operations, and ventilatory function tests were performed on 209 male foundry workers and 239 male control subjects. Ventilatory indices such as forced vital capacity (FVC) , one-second forced expiratory volume (FEV1), ratio of FEV1 to FVC(FEV1 %), maximal mid-expiratory flow(MMF), peak expiratory flow rate (PEFR) and maximal expiratory flow at 25, 50 and 75 % of expired FVC (FEF25, FEF50, FEF75 were obtained by analyzing forced expiratory spirogram and maximal expiratory flow-volume curve which were simultaneously measured by Vitalography in standing position. The results were as follows : 1. The average quartz concentrations of respirable dust were the highest in melting operation (0.079 mg/m3) and followed by molding operation (0.051 mg/m3), finishing operation (0.041 mg/m3) and coremaking operation (0.023 mg/m3) in the descending order. 2. No significant differences for mean values of all ventilatory indices expressed as percent of predicted value were demonstrated between smokers and nonsmokers In foundry workers and control subjects. 3. Mean values of all ventilatory indices except FVC of foundry workers were significantly lower than those of control subjects. 4. Mean values of FEV1 %, MMF, FEF25, FEF50 and FEF75 expressed as percent of predicted value tended to decrease with increasing cumulative dust exposure. 5. In foundry workers, proportions of workers with low MMF, FEF50 and FEF75 were markedly higher than those with other indices, and were significantly increased with increasing cumulative dust exposure. 6. In foundry workers, 2 workers(1.0 %) were diagnosed as silicosis and the profusion of radiographic opacities were category 1/0 and q type. With the above considerations in mind, it suggested that increasing exposure of silica dust be associated with progressive deterioration in ventilatory function of an obstructive nature and that MMF, FEF50 and FEF75 be more sensitive indices in the detection of the early obstructive changes of air flow of workers exposed to silica dust.

ICAM-l(Intercellular adhesion molecule-1) is an important early marker of immune activation and response. ICAM-1 is expressed on varous cell types and observed in a variety of diseases, including patients with asthma, melanoma, prostatic cancer, ovarian and colon cancer. Some authors demonstrated the expression of ICAM-1 protein in high-grade intraepithelial squamous neoplasia of cervix by immunohistochemistry and suggested that the expression was related to human papillomavirus infection. The aim of this study was to determine the serum levels of soluble intercellular adhesion molecule-1(sICAM-1) in patients with squamous cell carcinoma of the cervix, Serum levels of sICAM-1 were measured by enzyme-linked immunosorbent assay(ELISA), We evaluate invasive squamous cell carcinoma of the cervix (40), carcinoma in situ (16) and control (15) patients. Serum levels of sICAM-1 in healthy volunteers, in parients with carcinoma in situ and invasive cervical cancer were 150.1+/-41.3, 182.7+/-105.9, 189.8+/-60.0 ng/ml, respectively. Although the serum levels of sICAM-1 in patients with carcinoma in situ did not increase, serum levels of ICAM-1 in patients with invasive cervical cancer were significantly increased (control vs invasive cervical cancer, p < 0,05). From the above results, sICAM-1 is shed from the cancerous tissue in patients with squamous cell carcinoma of the cervix.

One of the primary functions for which bones have evolved is to act as a structural support. To achieve this, bones remodel throughout life so that their structure remains optimal for the prevailing mechanical environment. Bone remodeling consists of an initial phase of osteoclastic bone resorption followed by a bone formation period. Prostaglandins are potent regulators of bone formation and bone resorption that can have both stimulatory and inhibitory effects. Elevation of intracellular cAMP is an important intracellular signaling mechanism involved in the regulation of the expression of many proteins. In this study we examine whether PGE or DBcAMP affects osteoblastic activation or osteoclastic differentiation in mouse bone marrow cells and osteosarcoma ROS 17/2.8 cells. The effect of PGE and DBcAMP on the cell proliferation was measured by the incorporation of [3H]- thymidine into DNA. As a result, PGE2 (0.5-1 ug/ml) and DBcAMP (0.1-0.5 mM) inhibited the [3H]-thymidine incorporation into DNA in a dose dependent manner. The effect of PGE2 and DBcAMP on the induction of alkaline phosphatase (ALP) was investigated in ROS 17/2.8 cells cultured in medium containing 0.4% fetal bovine serum. PGE and DBcAMP stimulated ALP activity in the cells in a dose- dependent manner. PGE2 also increased the intracellular cAMP content in a dose- dependent fashion with a maximal effect at 0.5 ug/ml. ROS 17/2.8 cells release nitric oxide upon stimulation of PGE2 or DBcAMP with interferon-r. PGE2 and DBcAMP increase the phosphorylation level of CREB (cAMP response element binding protein) without any change on the amount of CREB protein. Also, PGE (10-6 M) and DBcAMP (10-4 M) significantly increase the generation of osteoclasts in mouse bone marrow cell culture system. In conclusion, the results of this study suggested that cAMP appears to be an important regulatory molecule in the processes of bone formation and resorption.

We describe a case of fine needle aspiration cytology of metastatic nasopharyngeal carcinoma in the lymph node of the neck presenting a predominantly spindle cell pattern. A 36 year-old male patient complained of dysesthesia on the right face and a palpable neck mass. Fine needle aspiration was done on the neck mass. Tumor cells were present in syncytial groups or singly with mainly spindle shaped nuclei, vesicular chromatin, thin and regular nuclear membrane, occasional prominent nucleoli and a few foci of cellular cohesiveness. The cytoplasm was scant and pale with ill-defined borders. Mature lymphocytes were present in the background of aspirates and within the tumor cell clusters. Histologically, the tumor of nasopharynx showed several areas of spindle cell pattern. Because the tumor cells showed a predominantly spindle shape with vesicular nuclear chromatin, the differential diagnosis of spindle cell sarcoma or granuloma of epithelioid cells were considered, but the characteristic morphology of the nuclei with vesicular chromatin and prominent nucleoli, and cellular cohesiveness were important in making the diagnosis of nasopharyngeal carcinoma. The possibility of metastatic carcinoma should always be considered in fine needle aspiration cytology of the lymph node in the neck because the incidence of metastatic carcinoma, particularly of the nasopharyngeal carcinoma in the lymph nodes of the neck is relatively high.

CD44 is a family of transmembrane glycoproteins involved in cell-cell and cell-matrix interactions. Expression of CD44 isofonns (splice variants) has been shown to be associated with poor prognosis in several human cancers. We evaluated the expression patterns of the CD44 isofortn (CD 44 splice variant v6) in infiltrating ductal carcinoma of the breast by immunohistochemical and RT-PCR method. Paraffin embedded blocks from seventy-five cases of mastectomized samples were analyzed immunohistochemically using monoclonoal antibody against CD44v6. CD44v6 was detected in fifty-seven cases (76%) of the tumor samples. Adjacent normal myoepithelial cells and ductal epithelial cells revealed focal positive reaction to CD44v6. Thirtytwo cases (80.0%) with lymph nodal metastasis revealed overexpression of CD44v6 monoclonal antibody, but twenty-five cases (71.4%) without nodal metastasis also showed positive reaction to CD44v6 monoclonal antibody, and there is no statistically significant value. Other prognostic factors of infiltrating ductal carcinoma, such as tumor size, histologic grade and hormonal receptors did not show any significant correlation with CD44v6 expression. The RT-PCR studies for 9 cases of infiltrating ductal carcinoma showed the same band patterns both in the normal and tumor tissues. From the above results, it is concluded that the expression of CD44v6 is not a valuable prognostic marker of infiltrating ductal carcinoma of breast.
