Current Clinical Features of Febrile Seizures in a Pediatric Emergency Room
Sang Won Lee, Young Min Youn, Jihei Cha, Anna Cho
Ewha Med J 2017;40(4):149-154.   Published online October 31, 2017
DOI: https://doi.org/10.12771/emj.2017.40.4.149
Objectives

To expand current knowledge on febrile seizures (FSs), the most common childhood seizure disorder, we investigated clinical features and risk factors of FS in the pediatric emergency department of a center in western Seoul.

Methods

Children with FS that visited the pediatric emergency room of the Ewha Womans University Medical Center from January to December 2014 were included in this study. A retrospective medical record review was conducted for a total of 404 seizure events relative to 265 patients.

Results

A total of 150 boys and 115 girls were enrolled. Children presenting their first FSs were 70.9% (n=188). Average age of FS onset was 28.9 months. Family history was reported in 95 children (36.8%) with higher relevance of paternal inheritance (44.2%, n=42/95). More than half of the seizures (56.4%, n=228/404) occurred on the first day of fever. The most common cause of fever was upper respiratory tract infection (65.8%, n=266/404). Children attending a daycare center had higher incidence of multiple FS compared to those cared for at home. Approximately one third of seizure events (31.7%, n=128/404) were admission cases, mainly because of prolonged fever.

Conclusion

FS is a common neurologic disorder with relatively high admission rate among pediatric emergency department visits. Daycare attendance is associated with current increased incidence of multiple FS. Further study with long-term follow up is necessary to expand knowledge on improving clinical care strategy in FS.

Review of Molecular Markers for Thyroid Cancer
Jae-Joon Han, Ki-Sook Hong
Ewha Med J 2012;35(1):3-10.   Published online March 31, 2012
DOI: https://doi.org/10.12771/emj.2012.35.1.3

The incidence of thyroid cancer has been rapidly increased in Korea. Although fine needle aspiration cytology is recommended for diagnosis of cancer, there are some limitations. Patients with indeterminate or suspicious cytology category in which malignancy cannot be ruled out usually undergone a thyroidectomy, however, only 10~25% of them finally diagnosed as cancer. According to the progress in understanding molecular mechanism, some mutations or other molecular alterations have been studied for the diagnostic and prognostic markers for thyroid cancer. The majority of papillary thyroid cancers have BRAF and RAS mutations or RET/PTC rearrangement, and approximately 80% of follicular thyroid cancers harbor a RAS mutation or PAX8/PPARγ rearrangement. These genetic alterations are mostly studied and current clinical guidelines suggested that these molecular markers may help management for patients with indeterminate cytology. In addition, recent studies demonstrated the high sensitivity and specificity of thyroid-stimulating hormone receptor mRNA in diagnosing cancer in patients with indeterminate cytology. For the detection of recurrent or residual thyroid cancer, serum thyroglobulin is the only circulating marker in clinical practice. However, it lacks sensitivity and is unreliable specifically in the presence of antibodies to thyroglobulin. Recent studies demonstrated a significant role of measuring the mRNA of thyroglobulin, thyroid peroxidase, thyroid-stimulating hormone receptor, and sodium/iodine symporter in peripheral blood for monitoring of the recurrence of thyroid cancer.

Recurred Cryptogenic Liver Abscess Secondary to Colon Cancer in a Non-diabetic Man
Seung-Jung Jun, Tae-Hun Kim, Min-sun Ryu, Da-Yeon Oh, Myung-Eun Song, Shina Lee, Jae-In Ryu, Hye-In Kim, Il-Hwan Moon, Kwon Yoo
Ewha Med J 2011;34(2):60-63.   Published online September 30, 2011
DOI: https://doi.org/10.12771/emj.2011.34.2.60

The causes of pyogenic liver abscess has been known as biliary tract disease or intrabadominal infection but the large proportions of the patients has no apparent underlying disorders. Recently colonic mucosal lesions were reported in patients with cryptogenic liver abscess and it has been suggested that colonic mucosal break may play a role in developing liver abscess in otherwise healthy patients. We experienced a patient of severe recurrent liver abscess complicated with endophthalmitis only 3 months after successful treatment of initial cryptogenic liver abscess and a polypoid colon cancer was discovered by chance. It seems prudent to proceed colonoscopic examination in patients with cryptogenic liver abscess especially when it is recurrent.
