Low Level of Hemoglobin S in a White Woman

Acne Keloidalis Nuchae in a White Woman

Acne keloidalis is a chronic inflammatory process that involves hair follicles of the nape of the neck and leads to hypertrophic scarring. In all references, it is noticed that this process occurs only in males after puberty and is especially seen in the black race. In this case, we report a 31-year-old white woman who had hypertrophic papules in the nape of her neck since 10 years ago and in p...

Unusual low sickle cell hemoglobin level.

Low proportions of glycosylated hemoglobin associated with hemoglobin S and hemoglobin C.

Using a cation-exchange chromatographic method, we found normal or subnormal values for glycosylated hemoglobin in a few diabetic patients with persistent hyperglycemia. Subsequent investigations revealed that these unexpected results had originated from black patients with diabetes. In view of common occurrence of abnormal hemoglobins in the Negro population, we subjected blood preparations to...

Algebraic Matching of Vulnerabilities in a Low-Level Code

This paper explores the algebraic matching approach for detection of vulnerabilities in binary codes. The algebraic programming system is used for implementing this method. It is anticipated that models of vulnerabilities and programs to be verified are presented as behavior algebra and action language specifications. The methods of algebraic matching are based on rewriting rules and techniques...

Leiomyosarcoma uteri in a white woman.

Sarcoma of the corpus uteri should be considered as a differential diagnosis in postmenopausal women presenting with severe abdominal pain, thought to be due to degenerative changes of leiomyoma uteri. We present a rare case of leiomyosarcoma in a postmenopausal White woman. Diagnosis was missed preoperatively for degenerating uterine fibroid.
