RESUMEN

BACKGROUND/AIMS: The aim of the present study was to evaluate the relationship between thyroid hormone levels and infarct severity in patients with ST-elevation myocardial infarction (STEMI). METHODS: We retrospectively reviewed thyroid hormone levels, infarct severity, and the extent of transmurality in 40 STEMI patients evaluated via contrast-enhanced cardiac magnetic resonance imaging. RESULTS: The high triiodothyronine (T3) group (> or = 68.3 ng/dL) exhibited a significantly higher extent of transmural involvement (late transmural enhancement > 75% after administration of gadolinium contrast agent) than did the low T3 group (60% vs. 15%; p = 0.003). However, no significant difference was evident between the high- and low-thyroid-stimulating hormone/free thyroxine (FT4) groups. When the T3 cutoff level was set to 68.3 ng/dL using a receiver operating characteristic curve, the sensitivity was 80% and the specificity 68% in terms of differentiating between those with and without transmural involvement. Upon logistic regression analysis, high T3 level was an independent predictor of transmural involvement after adjustment for the presence of diabetes mellitus (DM) and the use of glycoprotein IIb/IIIa inhibitors (odds ratio, 40.62; 95% confidence interval, 3.29 to 502; p = 0.004). CONCLUSIONS: The T3 level predicted transmural involvement that was independent of glycoprotein IIb/IIIa inhibitor use and DM positivity.

RESUMEN

Massive thoracoabdominal aortic thrombosis is a rare finding in patients with iatrogenic Cushing syndrome in the absence of any coagulation abnormality. It frequently represents an urgent surgical situation. We report the case of an 82-year-old woman with massive aortic thrombosis secondary to iatrogenic Cushing syndrome. A follow-up computed tomography scan showed a decreased amount of thrombus in the aorta after anticoagulation therapy alone.

RESUMEN

Vascular cannulation is an invasive procedure that carries the risk of complications such as pseudoaneurysms. Hemophilia, the most common severe bleeding disorder of inheritance, increases the risk of such complications through underlying hypocoagulability. Although surgical ligation has been considered the gold standard treatment, less invasive options are currently available. Here we present 2 hemophiliac neonates for whom clotting factor replacement and ultrasound (US)-guided compression were successfully used. A 3-week-old male infant and a 4-week-old male infant presented with masses in the left antecubital area and the radial aspects of both wrists, respectively, after arterial punctures. The US confirmed the presence of pseudoaneurysms located at the left brachial artery and right radial artery. US-guided compressions with clotting factor administration initially attempted while confirming a thrombus inside the pseudoaneurysm sac indicated successful management. Arterial cannulation and other procedures in hemophiliac neonates must be attempted with caution because pseudoaneurysms or uncontrolled bleeding may occur. If laboratory analyses or invasive procedures are needed for neonates with a bleeding tendency or a suspected hemophiliac disorder, arterial or venous cannulation requires more caution or should be avoided if possible. This case report suggests that US-guided compression and clotting factor administration are suitable modalities for the treatment of small pseudoaneurysms in hemophilia patients.

RESUMEN

Although tumor necrosis factor (TNF)-alpha antagonist is a successful treatment modality for various autoimmune diseases, including rheumatoid arthritis (RA), ankylosing spondylitis and psoriatic arthritis, many adverse effects have been reported. Cutaneous adverse reactions of TNF-alpha antagonist include skin rash, urticaria, lupus like rash, seborrheic dermatitis and different kinds of psoriasiform dermatitis. We report a case of psoriasiform dermatitis during TNF-alpha antagonist treatment in a 50-year-old woman with RA. The patient has been treated with adalimumab. After 2 months, she developed pruritic erythematous eruption and desquamative lesions on the head and limbs, which were defined as psoriasiform change by a skin biopsy. These skin lesions are successfully treated with combination therapy, including cessation of adalimumab, corticosteroid and phototherapy.

RESUMEN

PURPOSE: PubMed is not only includes international medical journals but also has a registration site for the ongoing clinical trials, such as ClinicalTrials.gov, under the supervision of US National Institutes of Health. We analyzed current status of vaccine clinical trials conducted by Korean investigators in database of ClinicalTrial.gov. MATERIALS AND METHODS: As of October 2012, there are total of 72 trials found on registry of vaccine clinical trials conducted by Korean investigators in database of ClinicalTrial.gov. These trials were analyzed and classified by conditions of vaccine clinical trials, biologicals or drugs used in vaccine clinical trials, status of proceeding research, and list of sponsor and collaborators. RESULTS: Total 72 trials of vaccine clinical trials conducted by Korean investigators are classified by groups of infection (64 trials), cancer (4 trials), and others (4 trials). Infections group shown are as follows: poliomyelitis, pertussis, diphtheria, tetanus, and Haemophilus influenzae type b (10), influenza (9), human papillomavirus infection (8), pneumococcal vaccine (6), herpes zoster (4), smallpox (4), hepatitis B (4), etc. One trial of each in lung cancer, breast cancer, prostate cancer, and colorectal cancer are shown in cancer group. One trial of each in Crohn's disease, ulcerative colitis, renal failure, and rheumatoid arthritis are shown in other group. CONCLUSION: Vaccine clinical trials conducted by Korean investigators in ClinicalTrial.gov reflects the current status of Korean research on vaccine clinical trials at the international level and can indicate research progress. It is hoped that this aids the development of future vaccine clinical trials in Korea.

RESUMEN

The mineral contents of the cultivation substrates, fruiting bodies of the mushrooms, and the postharvest cultivation substrates were determined in cultivated edible mushrooms Pleurotus eryngii, Flammulina velutipes, and Hypsizigus marmoreus. The major mineral elements both in the cultivation substrates and in the fruiting bodies were K, Mg, Ca, and Na. Potassium was particularly abundant ranging 10~13 g/kg in the cultivation substrates and 26~30 g/kg in the fruiting bodies. On the contrary, the calcium content in the fruiting bodies was very low despite high concentrations in the cultivation substrates, indicating Ca in the cultivation substrates is in a less bio-available form or the mushrooms do not have efficient Ca uptake channels. Among the minor mineral elements determined in this experiment, Cu, Zn, and Ni showed high percentage of transfer from the cultivation substrates to the fruiting bodies. It is noteworthy that the mineral contents in the postharvest cultivation substrates were not changed significantly which implies that the spent cultivation substrates are nutritionally intact in terms of mineral contents and thus can be recycled as mineral sources and animal feeds.
