The effect of Roentgen rays on carcinoma of the cervix has long been of great interest to both radiologists and gynecologists. Since most cervical carcinomas are treated by irradiation, any additional knowledge either concerning the radiosensitivity of cervical tumors or their ultimate prognosis would be of value. The vaginal smear is considered to be one of convenient and rapid methods to study the effects of radiation on cervical malignancy. We observed morphologic changes in 297 cytologic preparations obtained from 60 patients who had underwent irradiation for cancer of the cervix. With the morphologic parameters such as cytoplasmic vacuolization, cytoplasmic basophilia, multinucleated giant cell formation, polymorphonuclear leucocytes (PMNL) sticking and postradiation dysplasia, we analyzed the findings in relation to the follow up time interval. The most common effect was the cytoplasmic vacuolization with basophilia of basaloid cells, which were noted in more than 90% of followed patients. The multinucleated giant cell formation and PMNL stickering were noted in 38 cases(63%) and 48 cases(80% ) respectively. The differential diagnosis of postradiation dysplasia from recurrent or persistent carcinoma, reparative atypical cells, and regressing tumor cells was difficult and further study seems to be needed to clarify the more accurate morphologic features and biologic behavior.

BACKGROUND: Isolated infraspinatus tear is very rare and clinical features are not as well known, therefore the purpose of this study was to evaluate clinical characteristics and outcomes of isolated infraspinatus tear that authors experienced. METHODS: Authors reviewed 288 cases of full-thickness rotator cuff tear involving infraspinatus between 2010 and 2015, and retrospectively analyzed six cases of isolated infraspinatus tear. Perioperative clinical characteristics, postoperative functional outcomes of 6 months were investigated. Functional evaluation included visual analogue scale (VAS), range of motions, American Shoulder and Elbow Surgeons (ASES) score, and Constant score. RESULTS: Calcific tendinitis was accompanied in 4 cases (66.7%). Three of them received steroid injection or aspiration or extracorporeal shockwave therapy. Mean preoperative pain VAS was 7.1 (range, 5–9), and mean postoperative pain VAS at 6 months later was 1.6 (range, 0–5). Preoperative muscle strength by isokinetic muscle performance test showed 52% deficit of abduction and 37.6% deficit of external rotation. All 6 patients had arthroscopic repair of the infraspinatus tendon. All the patients at the 6 months follow-up exhibited clinical improvement in the Constant score (67.8 [range, 45–77] to 89.3 [range, 81–100], p=0.029), and ASES score (52.3 [range, 30–77] to 90.0 [range, 80–100], p=0.002). There was no healing failure on imaging. CONCLUSIONS: Isolated infraspinatus tendon tear was frequently accompanied by calcific tendinitis, but pathophysiologic relationship should need more study. To rule out neurogenic etiology, magnetic resonance imaging and electromyography would be helpful. Arthroscopic infraspinatus tendon repair and supraspinatus debridement showed relatively good result in painful shoulder.

STUDY DESIGN: This study was undertaken to document the effect of TGF-beta 1 and TGF-beta2 on the proliferation of lumbar facet joint capsule. OBJECTIVES: To study the effect of TGF-beta1 and TGF-beta2 on the proliferation of lumbar facet joint capsule and their proliferation mechanism. SUMMARY OF LITERATURE REVIEW: TGF-beta1 and TGF-beta proliferated mesenchymal tissue . This proliferatine mechanism was involved of PLC-gamma- 1 and tyrosine kinase in signalling. MATERIAL AND METHODS: Three lumbar facet joint capsule was cultured in DMEM-20 media. Its proliferatine and inhibited effect was studied under the metabolic inhibitors and trasnsforming growth factors . RESULTS: TGF-beta1, and TGF-beta2, increased cell proliferation dependent on time and dosage. Both of TGF-beta1, and TGF-beta 2, specific antisense oligonucleotide blocked tile autoc.me effect of growth factor, PLC-gamma-1 specific antisense oligonucleotide inhibited the effect of TGF-beta 1, and TGF-beta2, Genistin inhibited the effect of TGF-beta 1, and TGF-beta2, in time and dosage dependent manner. CONCLUSION: The cell proliferation of lumbar facet joint capsule was involved in PLC- gamma-1 and tyrosine kinase in signalling.

In open wounds of the hand that have exposed bone or tendons, management may be difficult. Compared with conventional cutaneous pedicle flaps, the fascial radial flap transfer has several advantages : (1) one operation is required by one operating team reliably and easy to perform, (2) the appearance is not bulky, (3) the donor area is closed primarily, and (4) the hand is free for early motion of the shoulder and the elbow. One potential disadvantage is the permanent loss of the contribution of the radial artery to the circulation of the hand. One case of the fascial radial flap transfer was performed at the Department of Orthopaedic Surgery of Hanyang University Hospital, and satisfactory result was obtained.

OBJECTIVES: This study was designed to investigate the prevalence of depressive symptoms in patients with breast cancer and to identify demographic variables and clinical characteristics impact on depressive symptoms and health related quality of life in patients with breast cancer in a university hospital. METHODS: Fourty-one patients with breast cancer were selected, who had visited the department of General surgery of the Wonkwang University hospital with a diagnosis of breast cancer regularly during the period November, 2010-May, 2011. All of subjects were evaluated for the depression, anxiety and the health related quality of life with Beck Depression Inventory(BDI), anxiety subscale of Personality Assessment Inventory(PAI) and Short-Form 36 Health Survey-Korean version(SF-36-K). Patients were divided into depressive symptoms and non-depressive symptoms group according to the BDI score. We compared SF-36-K between two groups, and analized multiple regression with depression and health related quality of life as criterion variables and demographic and clinical characteristics. RESULTS: The prevalence of depression in patients with breast cancer in a University hospital was 36.4%. Compared to the non-depression, depressed patients with breast cancer appeared significantly lower mean scores on six subscales in SF-36-K : Physical function(p<.01), Role-physical(p<.001), General health(p<.05), Social function(p<.001), Role-emotional(p<.001) and Mental health(p<.001). But there was no significant difference between two groups in Vitality and Bodily pain. Anxiety, level of education and presence of enforcement of chemotherapy(63.6%) were significant explanation variables for depressive symptoms. And type of surgery and age (55.8%) were significant explanation variables for health related quality of life. CONCLUSIONS: The prevalence of depressive symptoms in patients with breast cancer in a University hospital was 36%. The depressive symptoms had not only negative impact on the health related quality of life but also important explanation variable for health related quality of life. These results suggest that depressive symptoms in patients with breast cancer should be evaluated and treated for improving patient's health related quality of life.
