Myxoma constitue about 50% of a II primary cardiac, tumor (incidence 0.03%) and occur in any of the cardiac chambers, but about 75% of themare found in the left atrium. As is well known, left atrial myxoma usually simulates mitral valvular disease, and it tends to bring about postural syncope and frequent embolic manifestaticns. The clinical manifestation of left atrial myxoma upon the circulation are obstructive effects, embolic effects and constitutional effects. Diagnosis is now most of all important since surgery can be dramatically curable, whereas untreated myxoma apparently invariably lead to deadful course. Preaprative diagncsis by echocardiogram is so simple and accurate for detection of myxoma that awareness of mitral valvular heart disease with rapid deterioration must be screened. We have diagnosed one case of the left atrial myxoma preopratively by phonocardiogram, echocardiogram and levophase pulmonary angiograJ;n and successfully treated by operation under extra corporeal circulation. A 38 years old housewife was admitted to the National Medical Center because of dyspnea, and paroxysmal cough on occasions for prior to hospitalization. Operation was carried out by median sternotomy and left atriotomy with mild hypothermia under E.C.C. The left atrial myxoma was extirpated including endocardial fragment and its weight was 23gm. The hospital course was not eventful and she can work nowadays without symptoms.

Two cats were obtained from a cat kennel. Over the previous 7 days, the cats had shown cough, anorexia, depression and nasal discharge. In this study, the consensus PCR was able to detect successfully Mycoplasma species in nasal swab samples of the cats. To identify feline mycoplasma species from the lung tissue of the cats with pneumonia, Mycoplasma species-specific PCR reactions were conducted. As the results, we could identify M. felis by the positive amplified DNAs. On the other hand, we could not detect any positive reactions with the PCR reaction for M. arginini, M. canis, M. edwardii, M. cynos, M. gateae, M. maculosum, M. molared, M. opalescens, M. spumans and Mycoplasma HRC-689. In conclusion, we detected M. felis from the kenneled cats with pneumonia. We suggested that this consensus PCR would be useful and effective for monitoring Mycoplasma species in various kinds of animals including cats. The application of preceding consensus PCR before the species-specific PCRs may be the most recommended strategy for the identification of Mycoplasma spp.

Pancreaticothoracic fistula is a rare complication of acute or chronic alcoholic pancreatitis. It may present with various symptoms, like dyspnea, abdominal pain, cough, chest pain, fever, back pain, hemoptysis, fatigue, or orthopnea. Pancreaticothoracic fistula can be detected by magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), or computed tomography. MRCP has high sensitivity and fewer side effects, and thus it has recently been recommended as the first choice for the detection of pancreaticothoracic fistula. On the other hand, ERCP enables the detection and treatment of pancreaticothoracic fistula and allows for stent insertion; for this reason it is a commonly used modality in pancreaticothoracic fistula cases. Herein, the authors describe a case of pancreaticothoracic fistula detected by ERCP and MRCP that manifested only respiratory symptoms, namely hemoptysis and pneumothorax without abdominal pain, which commonly accompanies pancreatitis.

Nocardiosis is an uncommon opportunistic bacterial infection which becomes a significant health problem due to its increasing incidence and high mortality rate. However, many nocardiosis patients are underdiagnosed by physicians. To summarize the clinical characteristics and management of nocardiosis would help with better diagnosis and prognosis of nocardiosis. This retrospective study was conducted based on the medical records of nocardiosis patients between January 2015 and December 2021 in a tertiary hospital in China. Overall, 44 nocardiosis patients with 54 specimens were included. The patients consisted of 26 males and 18 females with a mean age of 50.4 ± 13.2 years. Among 44 patients, 26 (59.1%) were previously given immunosuppressive therapy. Connective tissue diseases (CTDs) were the most common underlying disease (16/44). The most frequent infection sites were the lungs (17/44) and skin or soft tissues (8/44). Common symptoms included cough (23/44), expectoration (18/44), fever (15/44), and subcutaneous abscesses (15/44). Forty-five out of 54 specimens (83.3%) required over 48 hours of culture time for nocardiosis detection. Thirty-six patients were cured or improved, 5 patients were discharged from the hospital due to poor prognosis, and 1 patient died. The average diagnosis time of poor prognosis cases was 19.7 days, which was significantly longer than those of improved or cured patients (7.3 days). Immunosuppressed patients comprise a large part of nocardiosis cases, which is worth attention in clinical practice. Early diagnosis, specifically through prolonged cultivation time of specimen, could help achieve better prognosis of nocardiosis patients.

Canine infectious respiratory disease (CIRD), also known as infectious tracheobronchitis or kennel cough occurs in a multiple-dog environment such as a shelter. In this study, we were collected 300 of nasal swab samples from dogs and 145 of environmental samples from a shelter to investigate respiratory pathogens of dogs in the Gwangju metropolitan city animal shelter from February to October, 2019. Bacteria cultures for isolation of Bordetella (B.) bronchiseptica and polymerase chain reaction (PCR) tests were performed for detection of eleven canine respiratory pathogens, namely Mycoplasma (M.) cynos, canine distemper virus (CDV), canine influenza virus (CIV), canine parainfluenza virus (CPIV), canine respiratory coronavirus (CRCoV), alpha-coronavirus (CCoV), canine pneumovirus (CnPnV), canine hepacivirus (CHeV), canine adenovirus type 2 (CAdV-2), canine herpesvirus-1 (CHV-1) and canine bocavirus (CBoV). Among 300 nasal swab samples, 148 samples (49.3%) were positive for at least one pathogens. CHV-1 was the most common pathogen, found in 95/300 (31.7%) samples. Subsequently, M. cynos (22.0%), B. bronchiseptica (2.3%), CPIV (2.0%), CBoV (1.7%), CCoV (0.7%) were detected. The detection rates of M. cynos and CHV-1 according to the duration of stay in the shelter were statistically significant. Among environmental samples, M. cynos, CCoV, CBoV and CHV-1 were detected in 45/145 (31.0%). These results indicated the need for disease control and prevention systems in the shelter.
