Enteroviral infections are common in neonates. One important infection pathway is vertical transmission from an infected mother to her neonate. Here, we report the early detection and successful treatment of a vertically transmitted fulminant enteroviral infection associated with myocarditis and hepatitis. The patient had a sudden onset of high fever on the fourth day of life and developed severe, rapidly progressing symptoms of disseminated intravascular coagulopathy (DIC), hepatitis, and myocarditis accompanied by tachyarrhythmia. As it was the peak season for enteroviral infections and both the mother and the patient's 36-month-old sibling had a high fever around the time of delivery, we suspected an enteroviral infection. Thus, we initiated prompt evaluation of enteroviral infection, as well as close observation and intensive care of the neonate. We strongly recommend evaluation for the possibility of vertical enterovirus infection in neonates when the mother is suspected of having a viral infection (e.g., high fever and negative results from bacterial infectious studies) around the time of delivery and when the neonate shows some early symptoms of infectious diseases such as thrombocytopenia, DIC, hepatitis, and myocarditis. Early detection of enteroviral infections and prompt implementation of proper treatment are key to reduce the risk of complications and mortality associated with enteroviral infections in neonates.

식도내 이물은 종종 어린이나 식도질환을 가진 환자, 죄수들, 정신박약자 및 정신질환자등의 위험성이 높은 성인에서 흔히 발생한다. 그러나 대부분의 이물은 저절로 위장관을 통과하나 날카롭고 뾰족하며 긴 이물은 위장관의 천공이나 혈관과 누공형성 및 다른 합병증을 초래할 수도 있다. 이물의 섭취는 대개 환자나 다른 목격자에 의하여 복용한 병력으로 진단할 수 있다. 그러나 어린이나 정신박약자는 병력을 얻을 수 없기 때문에 우선 의심하는 것이 중요한 진단방법이 될 수밖에 없다. 연하곤란과 연하통은 식도이물의 통상적인 증상이다. 주변기도의 압박으로 인한 호흡기 증상은 어린이에 흔하며 종종 성인에서도 관찰된다. 식도내 이물을 제거하는데 많이 사용되는 방법은 굴곡형내시경을 사용하여 제거하는 것이다. 이방법은 성인이나 어린이에서 전신마취없이 기존의 진정제 투여방법으로 시술할 수 있다. 이물제거에 사용되는 파지겸자와 올가미는 내시경이물제거술을 가능하게 하였고 굴곡형내시경에 사용되는 overtube는 기존의 강직 형내시경의 장점을 얻을 수 있어 뽀족하거나 날카로운 이물을 제거하는데 사용하게 되었다. 이런 내시경적이물제거 원칙을 잘 지키고 적절한 준비가 된다면 합병증이 거의 없이 98% 정도의 이물을 제거할 수 있다. 내시경을 사용하지 않는 여러 가지 방법은 천공의 위험성이 높고 흡인성폐렴을 유발할 수 있기 때문에 사용하지 않는 것이 낫다. 수술적인 처치는 천공이 되었거나 다른 이물로 인한 합병증이 있는 경우에만 드물게 적용된다.

Bridging bronchus (BB) is an extremely rare tracheobronchial anomaly. This anomaly is often associated with a sling left pulmonary artery (SLPA) and is diagnosed in infancy or at autopsy. A 29-year-old female patient with previous history of pulmonary tuberculosis was admitted because of persistent fever, cough and sputum. Fiberoptic bronchoscope and chest computed tomography revealed a bridging bronchus and associated atelectasis. The right middle and lower lobe was supplied by a bronchus which originates from the left main bronchus and bridges the mediastinum. There was no anomaly of a left pulmonary artery. Right middle and lower bilobectomy was performed.

Necrotizing bronchial aspergillosis usually occurs in the immumocompromised host. Aspergillus invades bronchial epithelium and forms endobronchial mass or endobronchial stenosis. A 78-year-old male patient with diabetus mellitus complaining of dyspnea and cough was admitted to our hospital. Plain chest X-ray and chest computed tomogram showed a large endobronchial mass and total collapse of left upper lobe of the lung. Bronchoscopic biopsy of the endobronchial mass revealed chronic inflammation. To confirm the endobronchial mass, we performed sleeve lobectomy of left upper lobe of the lung. Histologically the mass was diagnosed as necrotizing bronchial aspergillosis. We report a case of necrotizing bronchial aspergillosis in an elderly man who has diabetus mellitus with review of the literature.

Injury to the internal mammary artery secondary to blunt chest trauma is a rare condition. It is also uncommon to see extraplerual and mediastinal hematoma in these circumstances; this demands early diagnosis and active treatment. We report here on a 59 year old man who underwent surgery for extraplerual and mediastinal hematoma, and this was all due to injury of the internal mammary artery after blunt chest trauma. We also include a review of the relevant literature.

A 48-years-old woman was visited to our hospital because of incidental finding of intrapulmonary foreign body. Chest X-ray showed a 4cm sized foreign body in left upper lung field without adjacent fibrosis. Chest CT showed a sewing needle shaped foreign body of metallic density, located in the 113ft upper lobe. The foreign bodies including the needle were removed surgically using a wedge resection. The extracted needle was divided into three 4 cm pieces. Patient was discharged without other respiratory symptoms after surgery. We report a case of wedge resection in a patient with intrapulmonary needle in the left upper lobe, with review of literatures.

A cryotherapy system using cold air was developed. The developed system had superior low-temperature characteristics with various flow rates and nozzle sizes, and used R-404A, as a coolant, which has no destructive effects of Ozone layers. Flow rates and the treatment time can be easily altered during the operation. In addition, and alarm system was designed for the overload, overheat, and over-charge of the machine. For clinical applications, skin temperatures, intra-articular temperatures of the knee joint and intra-muscluar temperatures of the gluteal muscles were measured during and after the cryotherapy. After a 5-minute therapy, skin and intra-articular temperatures decreased by $23.3{\pm}4.7 and 4.1 {\pm}1.0^{circ}C$, respectively. A 5-minute cryotherapy was good enough to maintain low intra-articular temperatures for 2-3 hours. Resting intra-muscular temperatures in 2, 4, and 6cm deep in the gluteal muscle were $36.5{\pm}1.2, 36.9{\pm}0.2, 37.1{\pm}0.2^{circ}C$, respectively (p<0.05). Lowest temperatures in 2, 4, and 6cm depth were $35.1{\pm}0.7, 36.2{\pm}0.4, 36.9{\pm}0.3^{circ}C$, respectively (p<0.05). Temperatures after a 2-hour cold air application on the skin and in the muscle in dept도 of 2, 4, and 6cm were $32.2{\pm}1.1, 36.2{\pm}0.5, 36.6{\pm}0.3, 36.9{\pm}0.3^{circ}C$respectively (p<0.05). Temperatures on the skin and in the muscle significantly decreased after 2 hours, compared with before cold air application (p<0.05). The intra-muscular temperature was changed more slowly than the skin temperature, and the deeper the muscle, the lesser temperature changes. The effect of a 5-minute cold air application lasts up to 2 hours, and it seems that the rebound-rise of the temperature dut to the reactive vasodilatation does not occur in the gluteal muscle.

Coronary artery disease (CAD) and atrial fibrillation (AF) are known to share many risk factors. In particular, in the case of acute coronary syndrome, it may be difficult to clearly determine the diameter of the vessel due to complete occlusion of the vessel and thrombus. Thus, the relationship between the diameter of the coronary arteries was evaluated to be used as a reference data before the treatment of coronary arteries and drug selection in patients with AF. From January 2020 to August 2022, images of coronary angiography (CAG) with AF and normal sinus rhythm (NSR) on electrocardiography were target. In both subjects, images of normal coronary artery without lesions as a result of CAG were used. For all vessels, the diameters of the vessels were measured by dividing them into proximal, middle, and distal parts, and the measured diameters were divided by the average for evaluation. As a result of analyzing the left anterior descending artery diameter, the vessel diameter of the AF patient was 2.24±0.26 mm, which was smaller than that of the NSR patient, 2.86±0.38 mm, and was statistically significant. (p<0.001) As a result of analyzing the left circumflex artery diameter, the vessel diameter of the AF patient was 2.34±0.28 mm, which was smaller than the vessel diameter of the NSR patient, 2.87±0.29 mm, and was statistically significant. (p<0.001) As a result of analyzing the diameter of the right coronary artery, the vessel diameter of the AF patient was 2.68±0.5 mm, which was smaller than the vessel diameter of the NSR patient, 3.35±0.4 mm, and was statistically significant. (p<0.001) Considering that the coronary artery size of AF patients is significantly smaller than the coronary vessel size of NSR patients, it is considered as a useful study to be used as a reference for evaluating coronary artery diameter when the arrhythmia is AF. In particular, it is considered to be a study that can be helpful in diagnosing lesions, using drugs before and after surgery, and choosing to use auxiliary devices such as intravascular ultrasound.

A 4-year-old intact male Shih Tzu dog (5.4 kg of body weight) was referred with primary complaints of heart murmur and exercise intolerance. Diagnostic studies found severe valvular pulmonic stenosis (peak velocity of 6.4 m/s, pressure gradient 165 mmHg). The dog was treated with 3 cm (length) ${\times}$ 1.5 cm (diameter) of Palmaz biliary stent. The outcome of stent placement was favorable and remarkably reduced the severity of PS (6.4 m/s to 3.0 m/s of peak velocity). Clinical condition was remarkably improved with the absence of cardiac murmur, although mild pulmonic regurgitation existed from the day of stent placement. To our best knowledge, this case is the first clinical trial for treating PS with intravascular stent in Korea.

A 52-year-old man was taken to the emergency room following a motor vehicle accident. An echocardiogram showed moderate to severe tricuspid regurgitation due to rupture of the anterior chordae. An operation to repair the tarumatic tricuspid regurgitation was recommended; however, the patient refused because he was asymptomatic. Two years later, he developed mild generalized edema and dyspnea. The echocardiogram revealed progressive severe tricuspid regurgitation and annular dilatation. We treated the tricuspid regurgitation successfully using artificial chordae and ring annuloplasty.
