RESUMO
The etiology of anemia in adults is often multifactorial. This case highlights an uncommon combination of causes of anemia and the importance of a diagnostic workup guided by a patient's unique history, risk factors, and laboratory findings.
RESUMO
Infective endocarditis is rarely caused by Corynebacterium species. We report a unique case of Corynebacterium propinquum endocarditis in an otherwise healthy individual, and it is the first example of this organism causing culture-negative endocarditis. Conflicting clinical and microbiological data led to the use of sequencing to confirm the causative organism. This case illustrates C. propinquum as a cause of infective endocarditis, and it demonstrates the utility of ancillary molecular diagnostic techniques to identify etiologic agents in difficult cases of infective endocarditis.

In a 3-year field experiment, effects of reducing N fertilizer, straw returning and dicyandiamide (DCD) application on wheat yield and nitrogen budgets under wheat-fallow system were studied in rain-fed region. The experiment was carried out in Yangling of Shaanxi Province, and 4 treatments were installed including no nitrogen (CK), 220 kg N·hm-2 and no straw returning (FP), 150 kg N·hm-2 and straw returning (OPT), 150 kg N·hm-2, 7.5 kg·hm-2 DCD and straw returning (OPT+DCD). The results showed there was no remarkable difference for wheat yield between OPT and FP, but the N use efficiency of the former was 6.1% more than that of the latter, and the apparent N loss ratio was 7.2% less. OPT+DCD increased the average yield of winter wheat by 10.4% and 7.9% respectively compared to OPT and FP, the N use efficiency of winter wheat increased by 20.8% and 28.1%, and the apparent N loss ratio decreased by 8.5% and 15.1%, respectively. NH4+-N content in 0-20 cm of soil increased, accordingly the NO3--N content decreased in 40 to 45 days when DCD was applied.

Low-grade endometrial stromal sarcoma with intracaval and intracardiac extension represents a complex and often lethal condition. A case of a 40-year-old woman, who underwent hysterectomy for endometrial stromal sarcoma 4 years previously and developed recurrence with intracaval and intracardiac metastases, is presented. Operative management of resection of the intracaval and intracardiac tumor is described. The literature is reviewed in order to highlight the data on diagnosis and management of recurrent endometrial stromal sarcoma with vascular involvement, including the multimodality approach required in treating this disease.

Rare in occurrence, the following case of intrapulmonary lipoma is only the fifth known case in a female patient reported in the literature. Importantly, the incorporation of this lesion into the differential diagnosis during frozen section of a predominantly adipocytic lesion limited the extent of surgical intervention and provided the patient with an optimal standard of care.
