Surgical results of 59 patients with constant exodeviation having at least 2 months of follow-up were reviewed. Fifty nine cases of constant exodeviation were classified by fixation patterns into alternating exotropia 38 cases and monocular exotropia 21 cases. The final surgical results and success rates were compared between the 2 groups and were analyzed according to the length of postoperative follow-up period. The surgical results were as follows: in alternating exotropia, 63.2% was satisfactory, 28.9% undercorrected and 7.9% overcorrected, in monocular exotropia, 85.7% was satisfactory, 9.5% undercorrected and 4.8% overcorrected. The mean follow-up period was 5.3 months in alternating exotropia and 5.9 months in monocular exotropia. Final surgical results were not affected by the length of postoperative follow-up period in alternating exotropia. However, in monocular exotropia, there was a strong tendency to become exotropic with a long term follow-up period(2-17 months). We suggest that the fixation patterns could have an influence on postoperative stability in exodeviation.

BACKGROUND: Although there are improvements of clinical symtoms after bronchodilator inhalation in COPD patients, it has been noted that there was no increase of FEV1 in some cases. FEV1 did not reflect precisely the improvement of ventilatory mechanics after bronchodilator inhalation in these COPD patients. The main pathophysiology of COPD is obstruction of airway in expiratory phase but in result, the load of respiratory system is increased in inspiratory phase. Therefore the improvement of clinical symptoms after bronchodilator inhalation may be due to the decrease of inspiratory load. So we performed the study which investigated the effect of bronchodilator on inspiratory response of vetilatory mechanics in COPD patients. METHODS: In 17 stable COPD patients, inspiratory and expiratory forced flow-volume curves were measured respectively before bronchodilator inhalation. l0mg of salbutamol solution was inhaled via jet nebulizer for 4 minutes. Forced expiratory and inspiratory flow-volume curves were measured again 15 minutes after bronchodilator inhalation. RESULTS: FEV1, FVC and FEV1/FVC% were 0.92 +/-0.34L(38.3+/- 14.9% predicted), 2.5+/-0.81L (71.1 +/-21.0% predicted) and 43.1+/-14.5% respectively before bronchodilator inhalation. The values of increase of FEV1, FVC and PIF(Peak Inspiratory Flow) were 0.15 +/-0.13L(relative increase: 17.0%), 0.58+/-0.38 L(29.0%) and 1.0+/-0.56L/sec(37.5%) respectively after bronchodilator inhalation. The increase of PIF was twice more than FEV1 in average(p<0.001). The increase of PIF in these patients whose FEV1 was not increased after bronchodilator inhalation were 35.0%, 44.0% and 55.5% respectively. CONCLUSION: The inspiratory parameter reflected improvement of ventilatory mechanics by inhaled bronchodilater better than expiratory parameters in COPD patients.

The identification of therapeutic target genes that are functionally involved in stemness is crucial to effectively cure patients with metastatic carcinoma. We have previously reported that inhibition of ribosomal protein L9 (RPL9) expression suppresses the growth of colorectal cancer (CRC) cells by inactivating the inhibitor of DNA-binding 1 (ID-1) signaling axis, which is functionally associated with cancer cell survival. In addition to cell proliferation, ID-1 is also involved in the maintenance of cancer stemness.Thus, we aimed in this study to investigate whether the function of RPL9 could correlate with CRC stem cell-like properties. Here, we demonstrated that siRNA silencing of RPL9 reduced the invasiveness and migrative capabilities of HT29 and HCT116 parental cell populations and the capacity for sphere formation in the HT29 parental cell population. CD133+ cancer stem cells (CSCs) were then separated from CD133- cancer cells of the HT29 parental cell culture and treated with RPL9-specific siRNAs to verify the effects of RPL9 targeting on stemness. As a result, knockdown of RPL9 significantly suppressed the proliferative potential of CD133+ colorectal CSCs, accompanied by a reduction in CD133, ID-1, and p-IκBα levels. In line with these molecular alterations, targeting RPL9 inhibited the invasion, migration, and sphere-forming capacity of CD133+ HT29 CSCs. Taken together, these findings suggest that RPL9 promotes CRC stemness via ID-1 and that RPL9 could be a potential therapeutic target for both primary CRC treatment and the prevention of metastasis and/or recurrence.

Acute epiglottitis is a life threatening inflammatory disease of the upper airway mainly in children, however, the recent reports about acute epiglottitis in adults are increasing. The common symptoms are sore throat, dysphagia, dyspnea and salivary drooling. As the laryngeal edema progresses, the patient sits up, leans forward, with the chin thrust forward, having obvious difficulty breathing. Early recognition and proper airway maintenance until the inflammatory edema subsides are essential steps to avoid a possible life threatening upper airway obstruction. We experienced two cases of acute epiglottitis with sitting up position, chin thrust forward, having dyspnea.

BACKGROUND/AIMS: Cancer-induced bone pain (CIBP) is one of the most common pains in patients with advanced neoplasms. Because of treatment-associated side effects, more than half of cancer patients are reported to have inadequate and undermanaged pain control. New mechanism-based therapies must be developed to reduce cancer pain. Quetiapine is a commonly used atypical antipsychotic drug. We report a study of the potential analgesic effects of quetiapine in a mouse model of CIBP and examine the mechanism of bone pain by analyzing the expression of various nociceptors. METHODS: Fifteen male C3H/HeN mice were arbitrarily divided into five groups: control and, CIBP with no treatment, quetiapine treatment, opioid treatment, and melatonin treatment. The mice were tested for mechanical hyperalgesia by determining the nociceptive hind paw withdrawal pressure threshold. Tissues from tibia were removed and subjected to quantitative and qualitative evaluations of transient receptor potential vanilloid 1 (TRPV1), TRPV4, acid-sensing ion channel 1 (ASIC1), ASIC2, and ASIC3 expression. RESULTS: Paw withdrawal pressure threshold was improved in the quetiapine treatment group compared with the CIBP group. Expression of TRPV1, TRPV4, ASIC1, ASIC2, and ASIC3 in the CIBP with quetiapine treatment group was significantly lower than that in the CIBP group. CONCLUSIONS: Our results suggest an analgesic effect of quetiapine in the CIBP animal model and implicate TRPV and ASICs as potential targets for cancer pain management.

Acute myocardial infarction (AMI) is rare in patients with idiopathic thrombocytopenic purpura (ITP). We describe a case of an AMI during thrombocytopenia in a patient with chronic ITP. A 47-yr-old woman presented with anterior chest pain and a low platelet count (21,000/microliter) at admission. Urgent coronary angiography revealed total occlusion of proximal right coronary artery and primary percutaneous coronary intervention (PCI) was performed successfully. This case suggests that primary PCI may be a therapeutic option for an AMI in patients with ITP, even though the patient had severe thrombocytopenia.

BACKGROUND/AIMS: Acidic saline injections produce mechanical hyperresponsiveness in male Sprague-Dawley rats. We investigated the effect of milnacipran in conjunction with tramadol on the pain threshold in an acidic saline animal model of pain. METHODS: The left gastrocnemius muscle of 20 male rats was injected with 100 microL of saline at pH 4.0 under brief isoflurane anesthesia on days 0 and 5. Rats administered acidic saline injections were separated into four study subgroups. After determining the pre-drug pain threshold, rats were injected intraperitoneally with one of the following regimens; saline, milnacipran alone (60 mg/kg), milnacipran (40 mg/kg) plus tramadol (20 mg/kg), or milnacipran (40 mg/kg) plus tramadol (40 mg/kg). Paw withdrawal in response to pressure was measured at 30 min, 120 min, and 5 days after injection. Nociceptive thresholds, expressed in grams, were measured with a Dynamic Plantar Aesthesiometer (Ugo Basile, Italy) by applying increasing pressure to the right or left hind paw until the rat withdrew the paw. RESULTS: A potent antihyperalgesic effect was observed when tramadol and milnacipran were used in combination (injected paw, p=0.001; contralateral paw, p=0.012). This finding was observed only at 30 min after the combination treatment. CONCLUSIONS: We observed potentiation of the antihyperalgesic effect when milnacipran and tramadol were administered in combination in an animal model of fibromyalgia. Further research is required to determine the efficacy of various combination treatments in fibromyalgia in humans.

Sarcoidosis is a chronic multisystemic disorder of unknown cause characterized by presence of noncaseating Epithelioid granuloma in affected organ. It was first reported in 1887 by Hutchinson and is relatively common in western countries. But it is not commonly seen in East Asia including Korea. All parts of the body can be affected, but the lung is the most frequently affected organ. Other common site of involvement include lymph node, eye, skin, etc. It is known that 3~9% of all cases of sarcoidos is associated with bone involvement. Bone involvement usually cause no symptom and frequently affect bones in hands an feet. In many cases, it is known to be associated with skin involvement. We recently experienced one case of sarcoidosis which typically showed X-ray finding of sarcoidosis with associated skin lesion(lupus pernio) and report it with review of the literature.
