BACKGROUND: Recently elderly people have increased in Korea and increased demands of medical service. This study was carried out to identify diseases and health service utilization patterns of geriatric inpatients to provide better understanding and basis planning to meet the needs of expanding geriatric population. METHOD: We use data of `Patient Survey in Korea` in 1999 and analyzed characteristics of disease structure and utilization patterns of health care service of 54,013 cases of discharged patients aged 65 years or more. RESULT: The proportion of the elderly in total discharged patients is 14.7%. Male to female ratio is 1:1.3 and most common age group was between 65 and 69 years old. 84.2% of elderly patients were admitted at secondary or tertiary health care facilities. The most common disease in geriatric inpatients is malig- nancy in male and vascular disease in female. The average duration of hospitalization is 14.2 days. They stay longer than the nation wide average hospital length and stay longest when they are admitted by mental and behavioral disorders. CONCLUSION: Geriatric patients are admitted mostly with chronic degenerative diseases such as neoplasm and vascular disease. Elders prefer to be admitted to tertiary hospitals and oriental hospitals. They stay more in hospital.

Mixed squamous cell carcinoma and papillary carcinoma in the thyroid gland is a very rare malignant tumor characterized by rapidly progressive clinical course and radioresistance. A 63-year-oid woman had mixed squamous cell carcinoma and papillary carcinoma in the thyroid gland diagnosed by fine needle aspiration cytology (FNA), and the diagnosis was confirmed by histological examination. She had complained of a fixed, egg-sized mass of the anterior neck with hoarseness for 1 year. The findings of FNA consisted of sheets and clusters of polygonal epithelial cells with hyperchromatic, pleomorphic nuclei and eosinophilic, abundant, laminated cytoplasm. These findings were consistent with squamous cell carcinoma. Also, foci of papillary carcinoma were noted, and the cells exhibited nuclear groovings and intranuclear cytoplasmic inclusions. Total thyroidectomy specimen showed a diffusely infiltrating tumor in the left thyroid which was composed of mixed papillary carcinoma and well-differentiated squamous cell carcinoma. In junction between two components, squamous metaplasia of papillary carcinoma was noted.

Congenital arteriovenous malformations in the true pelvis are extremely rare : only 8 cases have been described in male patient. In most cases, the diagnosis may be obscure and the management is difficult due to frequent recurrence, so appropriate angiographic study is decisive in establishing the diagnosis and directing the mode of treatment. We report on 53 year old male patient who was treated with embolization due to congenital pelvic arteriovenous malformation with painless gross hematuria after erection or sexual intercourse. Diagnosis was established as periprostatic pelvic arteriovenous malformation by means of transrectal color Doppler ultrasonography and confirmed by angiography. Our attempt at management by embolization is described. A literature review and discussion of congenital arteriovenous malformation and worth of color Doppler ultrasonography are presented.

Nematomorpha, horsehair or Gordian worms, include about 300 freshwater species in 22 genera (Gordiida) and 5 marine species in 1 marine genus (Nectonema). They are parasitic in arthropods during their juvenile stage. In the present study, the used gordian worm was found in the feces of a dog (5-month old, male) in July 2014. Following the worm analysis using light and scanning electron microscopes, the morphological classification was re-evaluated with molecular analysis. The worm was determined to be a male worm having a bi-lobed tail and had male gonads in cross sections. It was identified as Gordius sp. (Nematomorpha: Gordiidae) based on the characteristic morphologies of cross sections and areole on the cuticle. DNA analysis on 18S rRNA partial sequence arrangements was also carried out, and the gordiid worm was assumed to be close to the genus Gordius based on a phylogenic tree analysis.

Avian trematodes, Urogonimus turdi (Digenea: Leucochloridiidae), were collected from the intestine of wild birds, Zoothera aurea, 2013–2017 in the Daejeon Metropolitan City, Korea. The body was ellipsoidal, attenuated and/or round ends, 1,987–2,120 long and 819–831 μm wide. The oral sucker was subterminal, rounded anteriorly, and 308–425×351–432 μm in size; the prepharynx and esophagus were almost lacking; pharynx was well-developed, 142–179×78–170 μm in size; intestine narrow, bifurcating just after pharynx, ascending to the oral sucker before looping posteriorly and terminating near the posterior end; ventral sucker larger, in almost median, 536–673×447–605 μm and approximately 1.5 times larger than oral sucker. A phylogenetic tree constructed with 18S ribosomal RNA showed inter- and intraspecific relationships. Based on these morphological and molecular findings, we report here a U. turdi from White’s thrushes in Korea.

Adult ascarid worms from the field mice, Apodemus agrarius, were observed with a light and scanning electron microscope, and molecularly analized with 18S rRNA gene. In the scanning electron microscope, 3 prominent labia were present in the anterior end of male and female worms, but the interlabia and gubernaculum were absent. Scanning electron micrographs showed cervical alae as vestigial organs that looked like a slightly uplifted superficial sewing stitch. Total 6 pairs of post-cloacal papillae were observed on the tail of the male worms. The tail of female worms was blunt and conical shape with a spine-like structure, mucron. The eggs were sub-globular, coated with the albuminous layer and 73 by 82 μm in average size. The superficial pits of T. apodemi egg (mean 8.6×6.7 μm) are obviously bigger than those of Toxocara spp. The partial sequence of 18S rRNA showed the sequence homology of Toxocara canis (99.6%), Toxocara cati (99.4%), Toxascaris leonina (99.4%), and Toxocara vitulorum (99.2%). Conclusively, it was confirmed that ascarid nematodes, Toxocara apodemi, recovered from striped field mice in Korea are taxonomically conspecific relationship with genus Toxocara and genetic divergence from other Toxocara species.

In this study, we intended to describe an unrecorded species of heterophyid trematode recovered from the small intestine of a Korean raccoon dog, Nyctereutes procyonoides koreensis, in Korea. A total of 13 small flukes were collected from a deceased Korean raccoon dog which was found in Chuncheon-si, Gangwon-do, Korea in May 2017. The trematode body were covered with many small spines, rectangular, broader than long, 807-1,103 µm long and 1,270-1,550 µm wide. Oral sucker in the anterior end slightly smaller than acetabulum. Pharynx muscular and well developed. Esophagus relatively long and sigmoid. Acetabulum small and located at median in anterior 2/5 portion. Ceca bifurcated at the anterior of genital pore and acetabulum and terminated at testis level. Testes larger, deeply lobed and located at the near of posterior end of body. Ovary small, triangular and located at the slight left of median and the anterior of left testis. Vitelline follicles dendritic and extend from the middle level of esophagus to the posterior portion of body. Eggs embryonated, operculated, small and 33-35×15-16 µm in size. Based on the morphological characteristics, the small heterophyid flukes recovered from the small intestines of Korean raccoon dog, N. procyonoides koreensis, were identified as Euryhelmis squamula (Digenea: Heterophyidae). Accordingly, this species of heterophyid flukes is to be a new trematode fauna in Korea by this study.
