We report three cases of rat mite dermatitis caused by Ornithonysus bacoti(Hirst, 1913), commonly referred to it as the tropicalrat mite. The first case, a 26-year old female had multiple pinhead sized vesicles with peripheral erythematous macule on the upper arms. The second case, a 34-year-old femal had multiple variable sized vesicles with erythematous base on the extremeties. The third case, a 43-year old male had multiple erythematous macules and papules with central punctum on the trunl: and extremities. Histopathologic sections from lesions of the first and second patient showed moderate perivascular lymphahistiocytic infiltration intermingled with some eosinophils. Causative mites, Ornithonyssus bacoti, female were collected around the skin lesion in rase 1, from the house dust in case 2 and furniture in case 3.

The ultrasound is also helpful to make the diagnosis of a variety of soft tissue tumors bacause of its safety, low cost, non-invasiveness and usefulness. We analysed ultrasonographic findings of 43 cases of soft tissue tumors which were histopathologically confirmed by biopsy and obtained the following results. The ultrasonography could effectively image not only the presence, size and location of the lesion, but also the relationship between the lesion and the adjacent structures. And this method could easily identify the consistency of the lesion, solid or cystic nature, be used to guide the percutaneous biopsy and aspiration without exposure to radiation, and afford the differentiation of malignant lesion from benign one. It could also define the eritities of soft tissue tumors by the nature of internal echo, margin of the lesion, internal echo homogeniety, post-acoustic enhancement, and so on.

The traditional treatment for the femoral shaft fractures in children is closed reduction by continuous traction, usually for 2–3 weeks, until the fracture has achieved partial stability, followed by spica cast immobilization. Fifty three cases, from 3 to 10 years of age, has been treated with closed reduction and immediate application of hip spica csst; all of them were closed fractures of femoral shaft and were not associated with head, abdominal, or vascular injuries. Any angulations in excess of acceptable ranges were corrected with wedging the cast; any overridings in excess of acceptable ranges were corrected by skeletal traction for 1 week, followed by incorporation of the pin to the cast. The resultant overriding and angulation of fragments were within acceptable ranges, and complications were not significant.This method of treatment not only is likely easy in nursing care and comfortsble to the patients but also has some advantages of short stay in the hospital, better utilization of hospital beds, and costsaving. This immediate hip spica cast immobilization seems to be a good method of treatment for the femoral shaft fracture in children.

Members of the genus Acinetobacter are recognized as newer pathogens of the nosocomial infection with an increasing frequency in recent years. Strains that belonged to A. calcoaceticus-A. baumannii complex (genomic species 1, 2, 3, and 13TU) were major groups associated with nosocomial infection. Phenotypic identification was unreliable and laborious method to classify Acinetobacter strains into 19 genomic species. Rapid and reliable identification of clinical isolates is essential to diagnosis and epidemiology of Acinetobacter. We investigated the suitability of amplified ribosomal DNA restriction analysis (ARDRA) to identify genomic species of 131 Acinetobacter isolates. The 16S rRNA genes (ribosomal DNA) were enzymatically amplified and the amplified PCR products were restricted independently with the enzymes, AluI, CfoI, and MboI. Genomic species of Acinetobacter was classified by the combinations of restriction patterns. The analysis was showed that restriction profiles were characteristic for each genomic species. One hundred fourteen isolates were identified as A. baumannii, twelve were identified as genomic species 13TU, and one was identified as genomic species 3. Four isolates were found to be unknown organisms. All of the isolates which were identified to A. baumannii by phenotypic tests were completely discriminated into A. baumannii and genomic species 13TU by ARDRA. This study demonstrates that ARDRA is a rapid and simple techniques for the identification of Acinetobacter species according to the genomic species.

The incidence of contrast media extravasation has been increasing gradually. Most contrast media extravasations only can cause pain, swelling and erythema. However, in more severe cases, skin necrosis, ulceration, or compartment syndrome may occur, often necessitating a surgery. Early diagnosis and treatment should be established on the spot in order to avoid such a severe damage. We present a case of 42-year-old woman with a compartment syndrome in the right upper extremity caused by extravasation of computed tomography contrast media.

PURPOSE: We performed this study to evaluate the usefulness and the limitation of magnetic resonance angiography in imaging portal vein and hepatic vein. MATERIALS AND METHODS: Magnetic resonance portography was performed in five normal subjects and seven patients with hepatomas, two patients with Budd-Chiari syndromes, one patient with liver cirrhosis and one patient with hepatic metastasis from stomach cancer. Magnetic resonance angiography was done with a 1.5-T Scanner. Breath-hold two-dimensional time-of flight images with spoiled gradient echo technique were acquired. Scan parameters were 34/8/40degrees(TR ms/TE ms/flip angle). The portal vein and the hepatic vein were selectively imaged by applying two presaturation bands. These images were then postprocessed by a maximum intensity projection algorithm. MRA findings were compared with ultrasonography in all cases of the hepatic disease, and conventional angiography (SMA portography) in four cases. RESULTS: In normal subjects, the splenic vein, intrahepatic and extrahepatic portions of the portal vein, and the hepatic veins were well visualized. In the patients with hepatic diseases, the varices (4 cases), the splenorenal shunts (2 cases), and the recanalized umbilical vein (1 case) were demonstrated. There were portal vein thrombosis in the cases of hepatomas and hepatic metastasis. In the cases of Budd-Chiari syndrome, the hepatic veins were not visualized and there were inferior vena cava obstructions with multiple collateral vessels. CONCLUSION: Compared with ultrasonography, MRP may be useful in evaluation of varices, splenorenal shunts, and other collaterals, though less accurate than conventional angiography. MRP can be useful as a noninvasive screening alternative in the evaluation of portal vein and hepatic veins.
