1.Prevalence of Theileria sergenti infection in Korean native cattle by polymerase chain reaction.
The Korean Journal of Parasitology 2003;41(3):141-145
This study was performed to investigate the prevalence of theileriosis and to compare the prevalence of this disease in Korean native cattle reared under different environmental conditions, namely, in a grazing area and a non-grazing area by polymerase chain reaction. Three hundred and one Korean native cattle (276 cows and 25 bulls) that had not received prior treatment or been vaccinated to prevent theileriosis were examined by PCR for Theileria sergenti infection from 2001 to 2002. In our study, the parasitemia range in T. sergenti-positive cattle by microscopy were from 0.1 to 3% (mean 0.8%). In terms of mean prevalence, 204 of the 301 Korean native cattle (67.8%) were positive reaction by PCR. Our results also revealed that the infection rate among cows (70.3%) was significantly higher than that among bulls (40.0%) (p < 0.01). T. sergenti infection among the over 3 year-old-group (75%) had a significant higher prevalence than that among the less than 3 year-old-group (61.8%) (p < 0.05). Our data also showed that grazing areas (76.1%) had the significant higher prevalence than non-grazing areas (51%) (p < 0.001). In conclusion, this study demonstrates that the prevalence of T. sergenti infection is high and that its prevalence in grazing cattle is higher than that in non-grazing cattle. Therefore, life-long treatment and the development of an optimal vaccine are needed to reduce the numbers of bovine theileriosis in both grazing and non-grazing areas.

Herein we report an experience of the vaginal ureterolithotomy. The patient was a 48-year-old woman with a juxtavesical left ureteral stone, which was vaginally palpable. Although this operation has limited indications, it is a safe and easy method of removing stones from the lowermost ureter especially in the women. This method seems to have considerable value to be attempted in the carefully select patients.

Myofibrosarcoma of the breast is a rare malignant mesenchymal tumor that has been reported in only four well documented cases so far. We report a case of myofibrosarcoma of the breast in an 88-year-old man who complained of a palpable mass for 1 year. Microscopically, the tumor consisted mainly of spindled cells, arranged in irregular fascicles and embedded in broad bands of dense hyalinized collagen. It showed ill-defined border infiltrating the adjacent adipose tissue, moderate cellular pleomorphism, and high mitotic rate (8~9/10 HPF). Immunohistochemical study confirmed myofibroblastic differentiation of the tumor cells with diffuse strong reaction for vimentin, smooth muscle actin, and fibronectin.

The dendriform pulmonary ossification (DPO) is a rare condition of unknown origin in which branching mature bony spicules, usually containing marrow, are found within the alveolar septa. DPO manifests slow progression over many years or may remain unchanged; spontaneous regression has not been recorded. Most patients have no symptoms directly attributed to the ossification, although they may have symptoms due to the underlying fibrotic process. We experienced a case of DPO in 38 year-old-man who presented with cough and sputum for a month. The chest X-ray showed marked coarsened interstitial lung markings in both lungs, especially in the lower lobes. Open lung biopsy was done. Grossly, there were significant dendriform osseous structures. Histologically, branching arrays of mature bone were found in the interstitium and occasionally in alveolar spaces. Some bony trabeculae contained fatty or cellular marrow. The alveolar septa showed fibrous thickening with chronic inflammation. The transition between fibrosis and bone tissue was observed. Our case suggests that dendriform pulmonary ossification may be a rare special manifestation of chronic fibrosing interstitial inflammation of the lung. Osseous structures seem to derive from metaplastic bone formation in the vicinity of undergoing fibrous process.

Cutaneous metastasis from renal cell carcinoma is not unusual, occurring in 3 to 7%, although it may be overlooked. We report a case of metastatic renal cell carcinoma in a 74-year-old man who was presented with a 1.5 x 1.5 x 0.5 cm-sized nodule on the right zygoma for 3 months. A skin biopsy demonstrated the typical clear cell adenocarcinoma with PAS(+) granules in the cytoplasm and honeycombed or glandular configuration, compatible with metastatic renal cell carcinoma. Kidney ultrasonogram and abdomina1 CT scanning showed a large cystic mass on the upper pole of the left kidney. Furthermore radiologic studies revealed multiple metastatic lesions in the lung, liver and brain. He died 4 months later.

Dystrophic epidermolysis bullosa is a rare, chronic non-inflammatory bullous disease, which easily forms bullae by minor mechanical trauma or spontaneously, is inherited either in an autosomal dominant or autosomal recessive fashion. We report herein two cases which presented with bullae, erosions and ulcers on extremities, buttock, chest, abdomen and face and loss of all nail since birth in two sisters. Bulla occured bencath the basal lamina histopathologically, anchoring fibrils were almost absent on electron miaoscopy in both cases. The two sisters represented dystrophic epidermolysis bullosa considering the absence of family history inheritcd in an autosomal dominant fashion and the clinical, histological and electronmicroscopic findings.

In general, pelvic fracture carries higher mortality especially from motor veicle accident, we have retrospectively reviewed charts and radiographs of 185 patients in order to identify clinical fading, kinds of fracture, hemodynamic changes and associated injuries in patients with pelvic fractures. We attempted to classify pelvic fractures according Young classification. The following results were obtained; 1. On age and sex distribution, the pelvic fractures showed peak incidence between 2nd decade and 5th decade. Male was affected more frequently than female, the ratio being male to female, 2.6 to 1. 2. The mechamisn of injury was motor veicle accident in 155(83.8%), fall in 25(13.5%), others in 5(2.7%). 3. The associated injuries of pelvic fractures: extremity, thoracic, urinary system, intraperitoneal and head injury. 4. Of the 185 cases of the pelvic fractures, simple pelvic fractures are 101 cases(54.6%), lateral compression in 39(21.1%), anteroposterior compression in 18(9.7%), vertical shearing in 17(9.2%), mixed pattern in 10(5.4%). 5. Retroperitoneal hematoma and urinary tracts injuries were the most common associated in mixed pattern. 6. The incidence of hemodynamically unstable fractures were 19.8% in simple pelvic fracture but, as expected was higher in major pelvic ring disruptions except to acetabular fracture(52.4%). 7. Mortality rates were 5.9% in all pelvic fractures but 10.7% in major pelvic ring disruptions except to acetabular fractures. Prognostic factor in pelvic fractures were the amount of hemorrhage and associated injuries, therefore early diagnosis and managements are essential to reduce the mortality in pelvic fracture.

Gottron's acrogeria syndrome is a rare genetic disease of unknown etiology with some features suggestive of accelerated aging. The typical clinical presentation consists of premature aging of the skin with atrophy of the cutis and the subcutis. After a brief review of the literature available on this syndrome, we report a case of Gottron s acrogeria syndrome in a 19 year-old man whose right rectus femoris muscle had a fibrotic contracture.
