Rothia species are gram positive, round to rod-shaped bacteria that are normally oral and respiratory tract flora. They were first isolated in 1967 from dental caries. We present a 69-year-old male with no risk factors for aforementioned bacteria however was found to have thickened anterior leaflet of the mitral valve with a small isoechoic lesion consistent with vegetation on Transthoracic echocardiogram. Blood cultures grew pan sensitive Rothia dentocariosa. Patient was treated with long-term antibiotics. This case adds to the limited number of cases of Rothia dentocariosa Endocarditis. Cardiac amyloidosis is a rare entity with a grave prognosis. Due to the low index of suspicion secondary to non-specific symptoms, it is often diagnosed at an advanced stage with multi-organ involvement. We report a case of systemic AL amyloidosis with predominant cardiac and renal involvement associated with multiple myeloma. A 60-year-old male presented with progressive anasarca, orthopnea and weight gain over 8months. On clinical examination, 3+pitting edema was found in bilateral extremities and scrotum. Serum N-type proBNP and troponin T were elevated, and EKG showed diffuse low voltage QRS, right axis deviation, and 1 degree AV block. Echocardiography revealed granular myocardium, biventricular hypertrophy, bi-atrial dilation and apical sparing pattern on global longitudinal strain which was suggestive of cardiac amyloidosis. Light chain assessment showed elevated kappa and lambda chains with kappa to lambda ratio of 16.2. Endomyocardial biopsy revealed AL type cardiac amyloidosis, and bone marrow biopsy confirmed the diagnosis of multiple myeloma. He received six cycles of bortezomib, cyclophosphamide, and dexamethasone but continued to deteriorate. He experienced an episode of cardiac arrest following which he had a return of spontaneous circulation but due to poor prognosis, the family opted for pursuing comfort measures only. Cardiac involvement in AL type amyloidosis imparts significant morbidity and mortality. The management of cardiac amyloidosis entails a multidisciplinary approach with an emphasis on cardiology and oncology. Despite the novel diagnostic modalities and treatment regimens, the outcome for AL-type cardiac amyloidosis remains poor.Cardiac involvement in AL type amyloidosis imparts significant morbidity and mortality.

The reported incidence is extremely low and estimated at 0.002% in the general population. We report a rare case of CAF in a middle-aged man, who was asymptomatic but incidentally found to have a gigantic CAF on a low-dose Computed Tomography scan of his chest. The case was presented to cardiothoracic surgeons. Since the patient was asymptomatic, they recommended medical management and continued close surveillance. The Left Coronary Artery or its branches are extremely uncommon site for CAF. With the advances in technology, the network of veins including coronary sinus has gained further clinical relevance. While technology has helped elucidate many aspects of these rare anomalies, mysteries still remain. With continued research, we can expect more cost-effective and less invasive interventional therapies to be developed in the near future.Background Thrombotic thrombocytopenic purpura (TTP) is a hematological emergency requiring prompt plasmapheresis. Conversely, vitamin B12 deficiency is a relatively benign diagnosis that can mimic microangiopathic hemolytic anemia, characterized by the presence of anemia, thrombocytopenia, indirect hyperbilirubinemia, markers of hemolysis, and schistocytes. This case series highlights the association of vitamin B12 deficiency and its TTP-like presentations. Cases The first case describes a 72-year-old man with shortness of breath and weakness. Diagnostics were notable for pancytopenia, schistocytes, and a low reticulocyte index. Intriguingly, total bilirubin was only mildly elevated however LDH and Haptoglobin were elevated and low, respectively. Additional diagnostic workup demonstrated an undetectable B12, elevated methylmalonic acid and elevated homocysteine. https://www.selleckchem.com/products/acetalax-oxyphenisatin-acetate.html Initiation of B12 supplementation resolved his pancytopenia. The second case describes a 57-year-old man with chest tightness, dyspnea on exertion, and night sweats. Diagnostic evaluation demonstrated pancytopenia, schistocytes, a low reticulocyte index, and a remarkably low B12. He had associated high methylmalonic acid and homocysteine levels, confirming the diagnosis. B12 supplementation resolved his pancytopenia. Conclusion The polysymptomatic presentation of vitamin B12 deficiency-induced pseudothrombotic microangiopathy highlights the vitamin's role in essential physiological cellular functions. Rapid recognition of the underlying etiology of microangiopathic hemolytic anemia is necessary as treatment approaches diverge greatly.Background Primary fallopian tube carcinoma (PFTC) is a rare gynecological malignancy though its prevalence may be underestimated given that most 'ovarian' serous cancers originate in the fallopian tube. Its diagnosis is challenging due to its vague signs and symptoms on presentation and it is frequently under-diagnosed pre-operatively. Case Presentation We present a case of a pre-menopausal woman who presented with vaginal bleeding. Her laboratory testing and physical examination were grossly unremarkable. Gynecologic ultrasound demonstrated multiple uterine fibroids and a double layer endometrium measuring 4.5 mm. More importantly, the left ovary was seen with a complex cyst with mildly echogenic fluid and a solid excerscence. These findings were suspicious for malignancy. The clinical and radiological findings with elevated CA-125 were consistent with a malignant process. Patient subsequently underwent a diagnostic laparoscopy, which required conversion to exploratory laparotomy, supracervical hysterectomy, bilateral salpingo-oophorectomy, right ureteral lysis, right para-aortic and right pelvic lymph node debulking and omentectomy.
