Cutaneous Serratia marcescens infection in two dogs.

We describe two canine cases of cutaneous infection caused by Serratia marcescens. A 2-year-old castrated male mixed dog (Case 1) presented with multiple ulcerations on the dorsal trunk, which were observed 4 days after shampooing. A 4-year-old male wolf shepherd mix dog (Case 2) presented with ulceration and purulent discharge on the nasal bridge. Cytological examination of both cases revealed pyogranulomatous inflammatory cells with rod-like infectious agents identified as S. marcescens in aerobic bacterial culture. Both patients were treated with oral antibiotics and topical chlorhexidine. Case 1 received enrofloxacin 10 mg/kg once daily for 1 week, followed by trimethoprim/sulfamethoxazole 15 mg/kg twice daily for 3 weeks. Case 2 received doxycycline 10 mg/kg twice daily for 4 weeks. No skin lesions were detected 2 weeks after the initial administration. The antibiotics were discontinued after a total 4 weeks of administration, and the skin lesions did not reappear.

Development of an in vitro submerged culture system to synthesize epidermal ceramides in canine keratinocytes.

Ceramides (CERs) in the stratum corneum (SC) are known to play a crucial role in determining skin barrier function in dogs. We aimed to develop an in vitro culture system that synthesized epidermal CER classes to better understand the synthesis of CER classes in canine SC-. Canine keratinocyte cells (MSCEK) at appropriate confluency were incubated with high Ca2+ (1.8 mM CaCl2) supplemented serum-free medium. Eight days post Ca2+ application, the surface of cultured MSCEK was broadly stained with anti-loricrin antibody implying that the keratinocytes had stratified into stratum granulosum. MSCEK cells synthesized heterogenous epidermal CERs, similar to those seen during the stratification of canine keratinocytes. CER fractions obtained from MSCEK cells were comparable to those from canine SC, including CER[EOS] (combination of ω-hydroxy fatty acids and sphingosines), CER[NP] (combination of non-hydroxy fatty acids and phytosphingosines), and CER[EOP] (combination of ω-hydroxy fatty acids and phytosphingosines), all of which are lowered in the SC during canine atopic dermatitis. Thus, the present study provides a simple culture system as a tool for in-depth analysis of CER production in canine keratinocytes.

Prognosis of surgical hernia repair in cirrhotic patients with refractory ascites.

BACKGROUND: Abdominal wall hernias are common in patients with ascites. Elective surgical repair is recommended for the treatment of abdominal wall hernias. However, surgical hernia repair in cirrhotic patients with refractory ascites is controversial. In this study, we aimed to evaluate the outcomes of elective surgical hernia repair in patients with liver cirrhosis with and without refractory ascites. METHOD: From January 2005 to June 2018, we retrospectively reviewed the records of consecutive patients with liver cirrhosis who underwent a surgical hernia repair. RESULTS: This study included 107 patients; 31 patients (29.0%) had refractory ascites. Preoperatively, cirrhotic patients with refractory ascites had a higher median model for end-stage liver disease (MELD) score (13.0 vs 11.0, P = 0.001) than those without refractory ascites. The 30-day mortality rate (3.2% vs 0%, P = 0.64) and the risk of recurrence (hazard ratio 0.410; 95% CI 0.050-3.220; P = 0.39) did not differ significantly between cirrhotic patients with refractory ascites and cirrhotic patients without refractory ascites. Among cirrhotic patients with refractory ascites, albumin (P = 0.23), bilirubin (P = 0.37), creatinine (P = 0.97), and sodium levels (P = 0.35) did not change significantly after surgery. CONCLUSION: In advanced liver cirrhosis patients with refractory ascites, hernias can be safely treated with elective surgical repair. Mortality rate within 30 days did not differ by the presence or absence of refractory ascites. Elective hernia repair might be beneficial for treatment of abdominal wall hernia in cirrhotic patients with refractory ascites.

Substance P as a potential biomarker of pain assessment in dogs.

BACKGROUND: Substance P (SP) is a neuropeptide that functions as a neuromodulator. It is released mainly in the brain stem and in nerve endings. AIMS: The present study aimed to provide fundamental data that may be applied to the assessment of pain in dogs by evaluating their serum SP concentrations. METHODS: Two groups of dogs were designated as pain groups that included 10 dogs with medial patella luxation (MPL) and 10 dogs with fractures, respectively, and 20 healthy dogs were enrolled as the control group. RESULTS: The SP concentrations in the serum of the pain groups reached 485.5 ± 250.1 pg/ml that was significantly higher than those of the control group, which reached 116.4 ± 38.5 pg/ml. In particular, serum SP concentrations in dogs with fractures (663.3 ± 225.3 pg/ml) were significantly higher compared to those of dogs with MPL (307.8 ± 105.3 pg/ml), indicating that serum SP levels increased when the dogs experienced greater pain. CONCLUSION: These findings propose the possibility that SP might be a useful biomarker for pain assessment in dogs. The present study may provide fundamental data that can aid in future pain management in dogs.

Effect of the sexual abstinence period recommended by the World Health Organization on clinical outcomes of fresh embryo transfer cycles with normal ovarian response after intracytoplasmic sperm injection.

This study was to investigate whether the sexual abstinence period (SAP) recommended by the World Health Organization (WHO) affects clinical outcomes. We compared the rate of clinical outcomes between 2-7 and ≥8 days of SAP in first fresh embryo transfer after intracytoplasmic sperm injection (ICSI) in groups of young maternal age (YMA: <38 years) and old maternal age (OMA: ≥38 years). We conducted a retrospective study of 449 first ICSI cycles with a normal ovarian response. SAP was identified before collecting the semen samples. Semen analysis was performed based on the guidelines recommended by WHO (2010). Sperm preparation was made using the swim-up method. Patients' baseline characteristics in the YMA and OMA groups did not differ. The rates of fertilisation, top-quality embryos on day 3, biochemical pregnancy, clinical pregnancy, ongoing pregnancy, abortion and implantation per cycle were not significantly different between 2-7 and ≥8 days of SAP in the YMA or OMA group. In conclusion, SAP beyond the recommended period by WHO was not associated with the rates of a lower fertilisation and pregnancy in human in vitro fertilisation (IVF). We think that a new criterion of SAP for clinical application in human IVF needs to be considered by WHO.

A multicentre, open, investigator-initiated phase IV clinical trial to evaluate the efficacy and safety of ingenol mebutate gel, 0·015% on the face and scalp, and 0·05% on the trunk and extremities, in Korean patients with actinic keratosis (PERFECT).

BACKGROUND: Ingenol mebutate gel is a novel, field-directed topical treatment for actinic keratosis (AK). Most pivotal studies have targeted Western populations. No clinical study has been conducted to investigate its efficacy and safety in Asian populations. OBJECTIVES: To evaluate the efficacy and safety of ingenol mebutate gel for treating AK of face/scalp and trunk/extremities in a large Asian (Korean) population. PATIENTS AND METHODS: In this multicentre, open-label, interventional, parallel-group, prospective phase IV study (PERFECT, trial registration no.: NCT02716714), the eligible patients were allocated into either the face/scalp or the trunk/extremities group, according to their selected treatment area location. After application of ingenol mebutate gel, the participants were followed up for 6 months. The primary efficacy endpoint was complete clearance (CC) of AK lesions in the selected treatment area at day 57. Quality of life was evaluated using Skindex-29. Safety endpoints included local skin responses, scar, pigmentation, pain and adverse events. RESULTS: In total, 78·1% [95% confidence interval (CI) 66·86-86·92%] of subjects had CC at day 57, with 76·6% (95% CI 64·31-86·25%) in the face/scalp group and 88·9% (95% CI 51·75-99·72%) in the trunk/extremities group. Among them, CC was sustained in 88·9% (48 of 54, 95% CI 77·37-95·81%) at month 6. The local skin responses significantly increased 1 day after the treatment compared with baseline, and decreased afterwards. Among the total subjects, 7·8% (6 of 77) had hyperpigmentation on the application area. Scars were not reported. CONCLUSIONS: Ingenol mebutate is effective for the treatment of AK in Asians, with tolerable safety profiles.

Effect of topical loteprednol etabonate with lid hygiene on tear cytokines and meibomian gland dysfunction in prosthetic eye wearers.

PurposeTo assess tear cytokine levels and clinical outcomes in meibomian gland dysfunction (MGD) in the blind eye of patients wearing an ocular prosthesis after 2 months of treatment with topical loteprednol etabonate and eyelid scrubs with warm compresses.Patients and methodsThis study included patients with MGD wearing a unilateral ocular prosthesis for more than 1 year. All patients topically received 0.5% loteprednol etabonate and were instructed to scrub their eyelids with warm compresses on the prosthetic eye for 2 months. We evaluated tear cytokine levels using Multiplex Bead Immunoassays, performed biomicroscopic examination of the lid margins and meibomian gland, conducted meibography imaging, and assessed MGD-related ocular symptoms using a questionnaire for the prosthetic eye before and 2 months after treatment.ResultsThirty consecutive patients were included. There were significant reductions in the levels of interleukin (IL)-6, interferon-γ, monocyte chemotactic protein-1, IL-8, tumor necrosis factor-α, and IL-1ß (P<0.001 for each cytokine). Moreover, there were improvements in ocular symptoms (P=0.001), lid margin abnormalities (P<0.001), meibomian gland expressibility (P<0.001) and meibography findings (P=0.037).ConclusionTopical loteprednol etabonate in conjunction with eyelid scrubs and warm compresses were effective in treating MGD in prosthetic eye wearers. Furthermore, tear cytokine measurements may serve as an additional approach for evaluating the efficacy of anti-inflammatory treatment for MGD in prosthetic eye wearers.

Preoperative clinical features of reactivated of Graves' orbitopathy after orbital decompression.

PurposeTo investigate the incidence and preoperative clinical features of reactivated Graves' orbitopathy (GO) after orbital decompression.MethodsThis study included patients with GO who underwent orbital decompression for disfiguring proptosis and not compressive optic neuropathy and received postoperative follow-up care for more than 12 months. Patients who experienced active inflammatory signs within 6 months of decompression were excluded from analysis. The demographic characteristics, ophthalmic manifestations, and biochemical parameters of the patients were analyzed for association with reactivation of GO by logistic regression analysis.ResultsOut of the 92 patients included in this study, seven (7.6%) experienced reactivation of GO after orbital decompression. The mean time interval between surgery and reactivation of GO was 36.3±14.3 weeks. Univariate logistic regression analysis identified age, existing smoking habits, and modified NOSPECS and Gorman scores as significant factors for the reactivation of GO. The results of multivariate logistic regression analysis revealed that smoking and modified NOSPECS and Gorman scores were associated with the reactivation of GO.ConclusionsQuitting smoking is important for the prevention of reactivation of GO after orbital decompression. Patients with severe symptoms, especially those with restrictive myopathy, should be carefully monitored for reactivation of GO after orbital decompression.

Immunohistochemical characterization of sebaceous epithelioma in two dogs.

This report describes two cases of sebaceous epithelioma and its immunohistochemical characterization with CK 14, CK18, p63, Ki67 and Bcl-2 immunostaining. Case 1 was a 12-year-old, intact English Cocker spaniel female presenting with multiple skin nodules over one year. Case 2 was a 7-year-old, spayed poodle female with a five-month history of solitary mass. Hematoxylin and eosin (H&E) staining showed that the nodules in both cases were irregular lobules comprised of epithelial cells around well-differentiated sebocytes. Neoplastic cells were positive for CK14 and p63 but were negative for CK18 cell marker. In addition, immunostaining for Ki67 proliferation marker showed 13.1% and 12.4% positive cells in the two cases, respectively. Furthermore, Bcl-2, which is highly expressed in human benign sebaceous tumors, was seen in basaloid cell nuclei and cytoplasm. CK14, CK18, p63, Ki67, and Bcl-2 antibody application provided further information for diagnosing sebaceous epithelioma and for prognosis in these two cases.

Impaired RBC deformability is associated with diabetic retinopathy in patients with type 2 diabetes.

AIM: Red blood cell (RBC) deformability, the ability of RBCs to change shape under stress, is known to be decreased in type 2 diabetes (T2D). However, as yet little is known of the association between RBC deformability and diabetic complications in T2D. For this reason, this study has investigated the association between RBC deformability and diabetic complications. METHODS: In this cross-sectional study, 452 T2D patients were initially enrolled. RBC deformability was measured using a microfluidic ektacytometer and expressed as an elongation index at 3Pa (EI@3Pa, %). RESULTS: A final total of 373 patients (mean age: 60.04±11.93 years; males: 201) were included in the study. When categorized into quartiles of RBC deformability, the lower EI@3Pa groups had higher glycated haemoglobin (HbA1c), triglycerides and prevalence of diabetic retinopathy compared with the higher quartiles (P<0.05 for trend). In particular, the EI@3Pa was significantly lower in patients with retinopathy than in those without retinopathy (30.53±1.95 vs 31.20±1.53, P=0.001). Between the lowest EI@3Pa quartile (Q1) to the highest (Q4, reference), the odds ratio (OR) for Q1 was 2.81 (95% CI: 1.21-6.49, P=0.004 for trend), after adjusting for age, gender, presence of hypertension and smoking, duration of diabetes, HbA1c, glomerular filtration rate and triglycerides. CONCLUSION: In terms of diabetic complications, the lowest EI@3Pa group was closely associated with only the risk of diabetic retinopathy in our study. These results suggest that RBC deformability might be contributory to the development of the microvascular complication.

The use of statins for the treatment of depression in patients with acute coronary syndrome.

This study aimed to investigate the effect of statins for the treatment of depression in individuals with acute coronary syndrome (ACS). We used 1-year follow-up data of a 24-week double-blind, placebo-controlled trial of escitalopram and a naturalistic prospective observational cohort study. Of 446 participants with comorbid depressive disorders and ACS at baseline, 300 participated in a randomised escitalopram trial and the remaining 146 participated in a naturalistic observational study. The participants in the two studies were approached for a 1-year follow-up investigation. Treatment response rates, defined as a ⩾ 50% reduction in the Hamilton Depression Rating Scale (HAM-D) and Beck Depression Inventory (BDI) scores, were used as the outcome variables. In the escitalopram trial, both HAM-D and BDI response rates were highest in patients taking escitalopram and statins together and lowest in patients receiving neither medication. Logistic regression analyses revealed that statin use was significantly associated with higher response rates on both the HAM-D and BDI at 1 year, whereas no such associations were found for escitalopram. In the naturalistic observational study, the response rates at 1 year did not differ significantly by statin use. Instead, the HAM-D response rate was significantly higher in patients taking lipophilic statins than in those who did not. In conclusion, statins may be effective for the treatment of depression independent of medical status and escitalopram use, and they may potentiate the antidepressant action of serotonergic antidepressants in patients with ACS.

Comparison of two- and three-point sutures for advancing the levator aponeurosis in Asian eyelids.

PURPOSE: To compare the functional and cosmetic outcomes of two- and three-point sutures for advancing the levator aponeurosis in blepharoptosis surgery on Asians. PATIENTS AND METHODS: This retrospective study examined 60 Asian patients with blepharoptosis who had undergone advancement of the levator aponeurosis: 34 patients (46 eyelids) had ptosis correction using the two-point suture technique and 26 patients (41 eyelids) had ptosis correction using the three-point suture technique. The postoperative marginal reflex distance (MRD1), lid height difference, and eyelid contour were evaluated. RESULTS: Twenty-seven (79.4%) of the 34 patients in the two-point group and 19 (73.1%) of 26 patients in the three-point group had a postoperative MRD1 of 2-4 mm, lids within 0.5 mm of each other, and a satisfactory eyelid contour; this difference was not significant. The rate of reoperation did not differ significantly between the two groups. CONCLUSION: Two- and three-point sutures for advancing the levator aponeurosis were equally effective for correcting blepharoptosis in Asians.

Effects of depression co-morbidity and treatment on quality of life in patients with acute coronary syndrome: the Korean depression in ACS (K-DEPACS) and the escitalopram for depression in ACS (EsDEPACS) study.

BACKGROUND: Depression is common after acute coronary syndrome (ACS) with adverse effects on prognosis. There is little evidence on whether depression treatment improves quality of life (QoL) in ACS patients. The aim of this study was to investigate the effects of co-morbid depression and its treatment on QoL in ACS. METHOD: In total, 1152 patients were recruited at baseline, 2-14 weeks after a confirmed ACS episode, and 828 were followed 1 year thereafter. Of 446 baseline participants with co-morbid depressive disorders, 300 were randomized to a 24-week double blind trial of escitalopram or placebo, while the remaining 146 received medical treatment only (MTO). QoL was measured by the World Health Organization Quality of Life -Abbreviated form (WHOQOL-BREF). RESULTS: At baseline, QoL was significantly lower in patients with co-morbid depressive disorder than those without. QoL improvement was significantly greater in those receiving escitalopram than those receiving placebo over the 24-week treatment period. In the 1-year follow-up, the better outcomes associated with escitalopram remained evident against both placebo and MTO. CONCLUSIONS: Depression was significantly associated with worse QoL even in patients with recently developed ACS. Depression treatment was associated with QoL improvement in ACS patients in the 24-week treatment period, the effects of which extended to 1 year.

Short-term effects of topical cyclosporine A 0.05% (Restasis) in long-standing prosthetic eye wearers: a pilot study.

PURPOSE: Long-standing prosthetic eye wearing induces ocular surface inflammation. We investigated the short-term effects of topical cyclosporine A 0.05% (Restasis) in patients with ocular discomfort resulting from long-standing prosthetic eye wearing. METHODS: This was a prospective, interventional case series. Patients who were unilateral prosthetic eye wearers over a period of 5 years were enrolled at a single institution from March to July 2013. The subjects were instructed to instill topical cyclosporine A 0.05% twice per day. Measurements were made pre-treatment and after 1 and 3 months of treatment. Outcome measures were the ocular symptom score, the lid margin abnormality score, the Schirmer test, and the tear meniscus amount, using Fourier-domain optical coherence tomography. RESULTS: In total, 20 consecutive patients (mean age: 60.1 years, 8 males, 12 females) were included. Ocular symptoms were improved after treatment for 1 month in all patients (ocular symptom score pre-treatment 76.83 vs 46.75 after treatment; P<0.001). There was no statistically significant difference in lid margin abnormality score or tear meniscus amount. The Schirmer test results were improved after treatment for 3 months (pre- and after treatment, 6.70 vs 11.40; P<0.001). CONCLUSIONS: Topical cyclosporine A 0.05% showed a satisfactory effect in long-standing prosthetic eye wearers. Ocular symptoms were markedly relieved in all subjects after treatment for 1 month.

Impact of personality and depression on quality of life in patients with severe haemophilia in Korea.

Among reports on the psychological variables that influence quality of life (QoL), none has addressed the impact of personality on QoL in patients with haemophilia. We investigated the impact of psychosocial variables including depression and personality on QoL in patients with severe haemophilia. A cross-sectional survey examining psychosocial and clinical characteristics was administered to Korean patients with severe haemophilia. Personality traits were ascertained using the 10-item short version of the Big Five Inventory, which quantifies five personality dimensions including extraversion, agreeableness, conscientiousness, neuroticism and openness. Patient QoL and depression were measured by the World Health Organization Quality of Life-abbreviated version and the Beck Depression Inventory (BDI) respectively. Multivariate linear regression analyses were used for each domain to determine the impact of psychological variables on QoL. Of the 53 subjects who consented to participate, 46 cases were finally analysed. Multivariate linear regression analyses demonstrated that agreeableness was significantly and positively associated with the physical health domain of QoL. Openness was independently and positively associated with the psychological and social relationship domains of QoL. BDI scores were significantly and negatively associated with all four domains of the QoL. Persistent pain and joint impairment showed strong associations with all domains in a univariate analysis, but the impact was attenuated after adjusting for psychosocial variables. Personality and depression had strong impacts on QoL independent of physical status in patients with severe haemophilia. Providing psychological screening and intervention are recommended for enhancing QoL in patients with severe haemophilia.

Relevance of TSH-receptor antibody levels in predicting disease course in Graves' orbitopathy: comparison of the third-generation TBII assay and Mc4-TSI bioassay.

AIMS: To investigate if TSH-receptor antibody (TRAb) levels measured in early Graves' orbitopathy (GO) stages are predictive of clinical disease course beyond 1 year after initial GO diagnosis and to compare performance of two newly developed TRAb assays (third-generation thyrotropin-binding inhibitor immunoglobulin (TBII) assay vs Mc4-thyroid-stimulating immunoglobulin (TSI) bioassay) in predicting disease course. METHODS: Newly diagnosed, untreated GO patients whose duration of ocular symptoms was less than 6 months were included. One year after initial diagnosis, all patients were classified as presenting either a mild (Group 1) or severe course (Group 2) according to their clinical manifestations. The measurements of two TRAb assays at initial GO diagnosis were used for analysis. RESULTS: Data from 112 patients were available for analysis. Seventy-three patients (65.2%) were designated as Group 1, and 39 patients (34.8%) as Group 2. Patients with higher initial TRAb levels demonstrated a higher risk of severe disease course upon multiple regression analysis (P<0.01). The cutoff values for the prediction of severe course of the third-generation TBII and Mc4-TSI assays were 10.67 IU/l and 555.10%, respectively, with assay specificities of 84.9 and 89.0%. The TBII assay predictive power (area under the curve (AUC)=0.817; 95% confidence interval (CI) =0.732-0.902) was equivalent to the TSI bioassay (AUC=0.868, 95% CI=0.803-0.934) (P=0.203). CONCLUSIONS: The predictive power of the third-generation TBII assay and Mc4-TSI bioassay are similarly strong. Measurement of TRAb using either third-generation TBII or Mc4-TSI in early GO periods would provide important prognostic information on future GO course.

The comparison of femoral and radial arterial blood pressures during pediatric liver transplantation.

BACKGROUND: Orthotopic liver transplantation (OLT) is frequently associated with dramatic hemodynamic changes; thus, it is critical to accurately monitor blood pressure. Although comparisons between femoral arterial blood pressure (FABP) and radial arterial blood pressure (RABP) have been reported in adult liver recipients, we compared FABP with RABP in pediatric recipients. METHODS: Thirty-five pediatric liver recipients younger than 13 years of age were included in this prospective, observational study. We measured simultaneous FABP and RABP in the femoral and radial arteries at nine time points during the procedure, including: baseline (after anesthetic induction); 1 hour thereafter; 30 minutes after the beginning of the anhepatic period as well as 0, 1, 3, 5, 15, and 60 minutes after graft reperfusion. RESULTS: Of the 35 pediatric liver recipients, 2 infants and 1 13-month-old child were excluded from the analysis because of radial arterial catheter malfunction. The remaining 32 patients including 16 infants and 16 children all showed significantly higher systolic and mean FABP than RABP during most stages of pediatric OLT. Overall diastolic FABP measurements were similar to diastolic RABP throughout the study. CONCLUSIONS: Systolic and mean FABP were significantly higher than RABP during most stages of pediatric OLT. Radial arterial catheter malfunctions were not uncommon during pediatric OLT. Our results indicated that it is useful to cannulate the femoral artery to accurately and reliably measure arterial blood pressure to detect hemodynamic instability during pediatric OLT.

Clinical features of thyroid-associated ophthalmopathy in clinically euthyroid Korean patients.

AIM: To compare clinical characteristics and thyroid-stimulating hormone receptor antibodies (TRAbs) in thyroid-associated ophthalmopathy (TAO) in euthyroid Korean patients with those in hyperthyroid patients. METHODS: Clinical activity scores (CASs), modified NOSPECS scores, exophthalmometry values, prevalence of optic neuropathy, restrictive myopathy and lid retraction, and the positivity and levels of TRAb (thyrotropin-binding inhibitor immunoglobulin (TBII) and thyroid-stimulating immunoglobulin (TSI)) were compared in 24 euthyroid (group A) and 139 clinical/subclinical hyperthyroid TAO patients (group B). RESULTS: Group A presented more clinically unilateral involvement than group B (79.2% vs 27.3%, P<0.001), less active (CAS 1.50 vs 2.26, P=0.014) and less severe clinical course (NOSPECS 3.38 vs 4.13, P=0.037). Lid retraction was more prevalent in group A than group B (91.7% vs 66.2%, P=0.014). Prevalence of optic neuropathy and restrictive myopathy, and the mean value of exophthalmometry were not different. Mean TBII levels were lower (7.20 IU/l) in group A than in group B (44.58 IU/l, P<0.001). A similar difference was found in the TSI bioassay (201.40% vs 425.19%, P=0.001). The positive rate of TBII in group A (34.8%) was significantly lower than in group B (90.8%, P<0.001). The positive rate of TSI was high in both group A (83.3%) and B (91.7%), with no significant difference (P=0.337). CONCLUSIONS: Patients with euthyroid TAO showed a less active and severe clinical course, more unilateral involvement, and lower levels of TRAb than those in patients with hyperthyroid TAO. These distinct clinical and biochemical characteristics might be useful in assessment of euthyroid TAO, and the TSI might be more sensitive for diagnosing these patients.

Indigo carmine-induced hypotension in patients undergoing general anaesthesia.

Indigo carmine is a blue dye that is widely applied to localise ureteral orifices. It is generally believed to be a safe, biologically inert substance, and hypotensive reactions are extremely rare. However, we experienced three cases of indigo carmine-induced hypotension within a period of two weeks.

Assessing Graves' ophthalmopathy-specific quality of life in Korean patients.

AIM: To investigate the clinical significance of Grave's ophthalmopathy-specific quality of life (GO-QOL) in Korean patients. METHODS: A cross-sectional study was conducted at the Department of Ophthalmology, Yonsei University College of Medicine, Seoul, Korea, on 98 consecutive Grave's ophthalmopathy (GO) patients. The GO-QOL survey provided by Terwee and colleagues and suggested by the European group on Graves' orbitopathy (EUGOGO) was translated into Korean language and distributed to study participants. Clinical severity was judged by scores of the modified NOSPECS classification, and inflammatory activity was measured by a seven-point scale of clinical activity score (CAS). RESULTS: The mean GO-QOL scores were 73.7 (standard deviation (SD), 26) for visual functioning, 61.9 (SD 26) for appearance, and 67.8 for total quality of life (QOL; SD 22). The worse QOL scores for each part were significantly associated with the higher modified NOSPECS score and CAS after adjusting for confounders such as age and sex (P<0.05, respectively). In particular, decreased QOL scores for visual function were significantly correlated with a higher grade of extraocular muscle involvement (P<0.05). Lower QOL scores for appearance were associated with more severe soft-tissue involvement and proptosis (P<0.05, respectively). CONCLUSIONS: GO-QOL suggested by EUGOGO showed correlation with objective clinical parameters. GO-QOL can be a simple and effective tool in the evaluation of the clinical and psychological illness of GO patients.
