Infective endocarditis (IE) is an uncommon but potentially life-threatening infection, which occasionally develops into acute severe valve insufficiency leading to the onset of heart failure, and necessitates timely intervention. However, the variable and atypical clinical manifestations always make the early detection of IE difficult and challenging.

A 45-year-old female who was previously healthy presented with exertional shortness of breath and paroxysmal nocturnal dyspnea. She also suffered from a significant decrease in exercise capacity, whereas her body temperature was normal. She had severe hypoxemia and hypotension along with a marked aortic valve murmur. Diffuse pulmonary edema and bilateral pleural effusion were observed on both chest X-ray and computed tomography scan. Transthoracic echocardiography was performed immediately and revealed severe regurgitation of the bicuspid aortic valve. Transesophageal echocardiography was further performed and vegetations were detected. In addition to adequate medical therapy and ventilation support, the patient underwent urgent and successful aortic valve replacement. Her symptoms were significantly relieved and the postoperative chest X-ray showed that pulmonary edema was significantly reduced. Histopathology of the resected valve and positive microorganism culture of the surgical specimen provided evidence of definite IE.

IE should be considered in critical patients with refractory heart failure caused by severe bicuspid aortic valve regurgitation.

Fournier's gangrene (FG) is a serious, aggressive and often deadly polymicrobial infection of the soft tissues of the perineum, the rectum and the external genital organs. It is an anatomical subcategory of necrotizing fasciitis, which has a similar etiology and treatment strategy.

A 60-year-old man was admitted to the hospital during severe acute respiratory syndrome coronavirus 2 pandemic with complaints of fever up to 38.9 °C, abdominal pain, and edema of the scrotum, the penis, the perineum, and the right gluteal region for 2 d. Computed tomography of the abdomen and the pelvis revealed extensive inflammatory infiltrations of the subcutaneous tissue of the hypogastrium, and the penis; along with liquefaction and presence of gas in the subcutaneous tissues of the scrotum, the perineum, and the right gluteal region. The patient was diagnosed with FG, and was urgently qualified to undergo surgery in the Department of Urology. After performing the necessary examinations, a resection of the necrotic tissues with bilateral orchiectomy and excision of the penile and scrotal skin was performed. After surgery, he was transferred to the intensive care unit for further management.

Early management prevents the resection of the other organs by inhibiting the contiguous spread of infection.

(

), a pathogen that commonly causes gastroenteritis, could potentially lead to a pandemic in Asia. Its pathogenesis and molecular mechanisms vary, and the severity of illness can be diverse, ranging from mild gastroenteritis, requiring only supportive care, to sepsis.

We outline a case of a 71-year-old female who experienced an acute onset of severe abdominal tenderness after two days of vomiting and diarrhea prior to her emergency department visit. MK-5348 ic50 A small bowel perforation was diagnosed using computed tomography. The ascites cultured revealed infection due to

Solitary fibrous tumors (SFTs) occurring in the parapharyngeal space are rare, and their final diagnosis depends on pathological and immunohistochemical analyses. Once the tumor is diagnosed, complete resection and regular postoperative follow-up are required.

A 40-year-old male patient with a right parotid gland mass discovered 8 years ago was admitted to hospital. The mass showed no tenderness or local skin redness. Imaging was carried out as the patient had stable vital signs and showed that the mass was a dumbbell-shaped tumor comprising a superficial tumor approximately 5 cm long and 3 cm wide in size that compressed the right parotid gland and a deep tumor located in the right parapharyngeal space approximately 4.5 cm long and 2.5 cm wide in size. Both tumors were connected in the middle. Prior to surgery, the tumors were considered to be parapharyngeal schwannomas. During surgical dissection, the tumors were found to be smooth and tough, without obvious adhesion to the surrounding tissues. The tumors were revealed to be a SFT following postoperative pathological analysis.

SFTs in the parapharyngeal space are rarely reported, and complete resection of such tumor is recommended. Adjuvant chemoradiotherapy is used in patients with extensive tumor invasion to lower the recurrence rate. Postoperative long-term follow-up is required.

Autoimmune antibodies are detected in many diseases. Viral infections are accompanied by several immunopathological manifestations. Some autoimmune antibodies have been associated with the immune response induced by virus or drugs. Thus, a comprehensive diagnosis of chronic hepatitis B combined with autoimmune hepatitis is required, and immunosuppressant or antiviral therapy should be carefully considered.

We present a case of a patient who had negative transformation of autoimmune antibodies during chronic active hepatitis B. A 50-year-old female who had a history of asymptomatic hepatitis B virus carriers for more than 10 years presented to the hospital with the complaint of weakness for 1 wk. Blood tests revealed elevated liver enzymes; the detection of autoantibodies was positive. Hepatitis B viral load was 72100000 IU/mL. The patient started tenofovir alafenamide fumigate 25 mg daily. Liver biopsy was performed, which was consistent with chronic active hepatitis B. The final diagnosis of the case was chronic active hepatitis B.
