Abstract Introduction: Soft tissue infections with Mycobacterium avium complex are more likely to appear in immunocompromised patients. However, they may rarely arise in non-immunosuppressed individuals. Aim: To present the case of an ear infection with Mycobacterium avium in the absence of demonstrable immunosuppression. Case Report: Clinical case description, blood tests, routine histology and tissue cultures. Discussion: A female, apparent immunocompetent patient presented with a 6-month reddish, oedematous and painless lesion with fine scaling in the right ear. Histology showed numerous granulomas, composed of epithelioid histiocytes without central necrosis. Cultures grew Mycobacterium avium. An unusual accidental ear injury was the portal of microbial entry. The patient’s lesion fully regressed after a 9-month course of antibiotics. Conclusion: Although M. avium infections are rare in immunocompetent patients, the possibility of such infections should be considered even in these subjects, when relevant clinical features and exposure to risk factors are present.

Abstract Background Yersinia pseudotuberculosis infection can occur in an immunocompromised host. Although rare, bacteremia due to Y. pseudotuberculosis may also occur in immunocompetent hosts. The prognosis and therapeutic strategy, especially for immunocompetent patients with Y. pseudotuberculosis bacteremia, however, remains unknown. Case presentation A 38-year-old Japanese man with a mood disorder presented to our hospital with fever and diarrhea. Chest computed tomography revealed consolidation in the right upper lobe with air bronchograms. He was diagnosed with pneumonia, and treatment with intravenous ceftriaxone and azithromycin was initiated. The ceftriaxone was replaced with doripenem and the azithromycin was discontinued following the detection of Gram-negative rod bacteria in 2 sets of blood culture tests. The isolated Gram-negative rod bacteria were confirmed to be Y. pseudotuberculosis. Thereafter, he developed septic shock. Doripenem was switched to cefmetazole, which was continued for 14 days. He recovered without relapse. Conclusions We herein report a case of septic shock due to Y. pseudotuberculosis infection in an adult immunocompetent patient. The appropriate microorganism tests and antibiotic therapy are necessary to treat patients with Y. pseudotuberculosis bacteremia.

CONTEXT: Tuberculosis of the prostate has mainly been described in immunocompromised patients. However, it can exceptionally be found as an isolated lesion in immunocompetent patients. CASE REPORT: We report a case of prostatic tuberculosis in a young, healthy and immunocompetent patient with unremarkable findings from intravenous urographic examination. Computed tomography showed an abscess in the prostate and Mycobacterium tuberculosis was isolated in a urine culture. Treatment with isoniazid, rifampin and pyrazinamide was successful.

Pulmonary nocardiosis is a rare bacterial infection that may lead to severe disease in immunodeficient patients and usually not so common in immunocompetent patients. The report is about a 57-year-old male with Norcardiosis. His sputum and Bronchial Alveolar Lavage (BAL) were negative for acid-fast bacilli. Nocardia species was isolated in BAL culture. He was started on Trimethoprim/Sulfamethoxazole and Clarithromycin, which was later continued for six months.

Pasteurella multocidacolonizes animal scratches and bites. This bacterium was described to cause sepsis or endocarditis mainly in immunocompromised patients. We report the case of a 92-year-old woman presenting at the Emergency Department with coma and fever a week after the bite of her cat. The cat bite was misdiagnosed at admission partly due to an underestimation of this event by the patient’s relatives. An inflamed area localized at perimalleolar skin of the right leg was detected. Laboratory biomarkers of inflammation were elevated. The cerebral computed tomography (CT) scan with angiographic sequences showed a complete occlusion of right intracranial vertebral artery. Total body CT scan and abdominal echocardiography were negative for foci of infection. Three consecutive blood cultures were positive forPasteurella multocida. A diagnosis of sepsis byPasteurella multocidawas made, and the patient recovered after a specific antimicrobial treatment. In order to confirm the animal transmission, the cat saliva was cultured and found positive forPasteurella multocidawith a similar antibiotic sensitivity to that isolated from the patient. In conclusion, the case of a patient with coma and fever after a cat bite was presented. The transmission of pathogens from pets has to be carefully considered as an important route of infection in immunocompetent patients.

Background: Single Coronary Artery (SCA) is a rare, most commonly asymptomatic, congenital anomaly which is usually discovered incidentally during investigations. This entity consists of a single coronary artery supplying the entire myocardium. It may be classified based on the origin and the course of the artery. Depending on the patient's presentation and its severity, medical or invasive interventions may be warranted. Case Report: A 65-year-old female patient known to have diabetes and hypertension presented to our emergency department with chest pain and discomfort. Blood tests and electrocardiography (ECG) showed no significant abnormalities, but on coronary angiography, we suspected an anatomical variation. Computed tomography angiography (CTA) confirmed our suspicion revealing a single coronary artery supplying the entire myocardium and arising from the right sinus of Valsalva. The patient received medical therapy and was discharged home. Conclusion: We presented this case of Single Coronary Artery due to the rarity of this diagnosis. Presentation, treatment plan, and prognosis typically vary depending on the subtype of the anomaly. Early recognition is very important, especially in young adults.

Mycobacterium avium complex (MAC) infection mainly causes pulmonary disease. However, in 20% to 30% of cases, it also induces various extrapulmonary diseases. Disseminated MAC infection occasionally occurs in immunocompromised patients but very rarely in immunocompetent patients. An 80-year-old immunocompetent woman presented with multiple chronic wounds on the scalp that had not improved despite prolonged treatment. A scalp abscess caused by disseminated MAC infection 4 years ago had gone through repeated cycles of improvement and aggravation despite continued use of anti-mycobacterial agents and active wound care. Enhanced brain computed tomography and magnetic resonance imaging revealed multiple skull defects and abscesses invading the dura mater. Under general anesthesia, the infected scalp skin and bone were sufficiently removed, and the bone and soft tissue defects were repaired with cranioplasty using a titanium mesh plate and local flap. As exemplified in this case, multiple chronic wounds unresponsive to treatment need to be screened for MAC infection. As chronic MAC infection in the scalp can cause skull destruction and brain infection, it needs to be treated aggressively at an early stage to prevent serious morbidity and mortality. Effective MAC infection management involves adequate medication, regular follow-up imaging, and active surgical procedure.
