Multiple cerebral infarction developed in a 36-year-old woman with adenocarcinoma of the right lung with direct cardiac invasion. Neurological examination and brain MRI showed findings of ordinary infarction. Transesophageal echocardiography showed left atrial pedunculated mass which was the potential source of embolism. We report a rare case who had such multiple spontaneous tumor emboli large enough to result in clinically detectable cerebral infarction.

Chest X-ray radiography and computed tomography, the two mainstay modalities in thoracic radiology, are under activeinvestigation with deep learning technology, which has shown promising performance in various tasks, including detection,classification, segmentation, and image synthesis, outperforming conventional methods and suggesting its potential forclinical implementation. However, the implementation of deep learning in daily clinical practice is in its infancy and facingseveral challenges, such as its limited ability to explain the output results, uncertain benefits regarding patient outcomes, andincomplete integration in daily workflow. In this review article, we will introduce the potential clinical applications of deeplearning technology in thoracic radiology and discuss several challenges for its implementation in daily clinical practice.

Primary pulmonary hypertension is a rar, incurable, and progressive clinical entity. When associated with pregnancy, the prognosis of primary pulmonary hypertension is worsened with maternal mortality rates of at least 50%. The patient was a 29-year-old mother in her 2nd pregnancy, with previous uncomplicated gestation, 5 years ago. She had been well until the 28th week of present gestation when she was admitted because of increasing dyspnea on exertion. She was a housewife with no remarkable family and past histories. We have experienced a patient with primary pulmonary hypertension in pregnancy. She was treated with an oral calcium-channel blocker and low-molecular-weight heparin and was delivered vaginally with good maternal and fetal outcome. So we report a case of primary pulmonary hypertension associated with pregnancy and review literature.

The present study was designed to elucidate the effects of the Co-60 r irradiation and/or calcium deficient diet on the dentin and cementum formation of rat molar. The pregnant three-week old Sprague-Dawley rat were used for the study. The experimental group was divided into two groups, irradiation/normal diet group and irradiation/calcium-deficient diet group. The control group was non-irradiation/normal diet group. The abdomen of the rats at the 19th day of pregnancy were irradiated with single absorbed dose of 350 cGy. The rat pups were sacrificed on the 14th day after delivery and the maxillae including molar tooth germ were taken. The specimens including the 1st molar tooth germ were prepared to make tissue sections for light and trasmission electron microscopy. Some of tissue sections for light microscopy were stained immunohistochemically with anti-fibronectin antibody. The results were as follows ; 1. The Hertwig s epithelial root sheath cells, which are related to the differentiation of the tooth-forming cells, showed irregular cellular arrangement, decrease of intercellular junctional complex, and decreased immunoreactivity to the fibronectin after irradiation. These were more severe in the irradiation/calcium-deficient diet group. 2. The cementoblasts at the cementum-forming area showed chormatin clupings after irradiation. The immu noreactivity to the fibronectin was weaken after irradiation, especially irradiation/calcium-deficient diet group. 3. The odontoblast at the dentin-forming area showed increase of lysosomes in the cytoplasm and destruction of intercellular junctional complex. The irradiation/calcium-deficient diet group showed decrease of number and density of th electron dense particles and a large number of vacuoles scattered in the dentin matrix. The immunoreactivity was weaken.

There have been a few reports of occupational asthma caused by Tetranychus urticae in fruit farmers or greenhouse workers. We report a case of bronchial asthma induced by Tetranychus urticae from a pear orchard in Cheonan city. An 18-year-old female student living around a pear orchard suffered from intermittent cough, rhinorrhea, and dyspnea for the 3 years. Her PC20 -methacholine was 0.15mg/ml, and skin prick test done with 55 inhalant allergens showed negative responses except Tetranychus urticae extract which was prepared with highly parasitized pear leaves. Bronchial provocation test with Tetranychus urticae extract showed a dual asthmatic response. These findings indicate that Tetranychus urticae, which include parasites in fruit trees, herba,ceous plants, and greenhouse cultures, can cause IgE-mediated bronchoconstriction in Korea.

Staphylococcal cassette chromosome mec (SCCmec) type and coagulase serotype are important epidemiologic factors in methicillin-resistant Staphylococcus aureus (MRSA). To investigate correlation between SCCmec type and coagulase serotype of MRSA, we analyzed SCCmec types of MRSA strains isolated from clinical sources and compared the results to coagulase serotypes and antimicrobial susceptibility patterns. A total of 108 MRSA isolates were classified into four SCCmec types: II (55.6%), IV (21.3%) III (13.0%) and IIIA (8.3%), and five coagulase serotypes: II (54.6%), IV (21.3%), V (18.5%) and VII (2.8%). All of coagulase type II, IV and V strains belonged to SCCmec type II, III/IIIA and IV, respectively. SCCmec types II, III and IIIA were multidrug resistant, whereas SCCmec type IV strains were non-multidrug resistant except beta-lactams and erythromycin. The data provide that there is a significant correlation between SCCmec types and phenotypic characteristic of coagulase serotypes.
