Multiple myeloma is a hematological cancer mostly located in the marrow of the vertebrae, pelvis, and thighs. Although the presence of extramedullary disease in the central nervous system is rare, herein, we report a complicated case of multiple myeloma in the spinal cord.

Acute ischemic stroke (AIS) has become a serious health problem in many countries because of its poor outcome and worsening epidemic trend. Early identification of genetic risk factors and physiological indicators for stroke occurrence may help to reduce the incidence of stroke. Therefore, we conducted a case-control study including 50 AIS patients and 50 healthy individuals from a Chinese population to explore the association between AIS and patient complete blood profiles and the association between AIS and the genetic polymorphism K469E in intercellular adhesion molecule-1 (ICAM-1). Compared to the control group, AIS patients showed a high percentage of mononuclear cells, low platelet count, low ratio of platelet to lymphocyte count, high frequency of the 469K allele, and low frequency of the 469E allele. White blood cell count, percentage of neutrophils, percentage of lymphatic cells, platelet distribution width, mean platelet volume, and platelet hematocrit levels showed no significant differences between the 2 groups and between different genotypes. Our results suggested an association of elevated levels of mononuclear cells and reduced platelet count with higher AIS risk. Our results also supported the hypothesis that the KK genotype at the K469E locus in ICAM-1 is a risk factor for AIS.

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To examine the efficacy and safety of the different routes of haloperidol administration for people with schizophrenia.

Histologic sections of seven squamous cell carcinomas (SCC), 13 basal cell carcinomas (BCC), and a Bowenoid actinic keratoses were examined for expression of HLA class 1 antigens (HLA-ABC) using a monoclonal antibody and an immunoperoxidase technique. Expression of beta 2-microglobulin was examined with a polyclonal antibody method. Neither cell marker was detected within the Bowenoid actinic keratoses. Squamous cell carcinomas and basal cell carcinomas exhibited decreased expression of both HLA-ABC and beta 2-microglobulin and often did not express these antigens at all. HLA-ABC was present in only two of 13 basal cell carcinomas and four of seven squamous cell carcinomas. beta 2-microglobulin was present in one of 13 basal cell carcinomas and two of seven squamous cell carcinomas. When present, these antigens often were present in a few areas of the tumor, but absent in others. In both SCC and BCC, both antigens were usually lost simultaneously. In all tumors with beta 2-microglobulin, HLA-ABC also was retained. There was no apparent relationship of anatomic site or type of tumor with retention of surface antigens. Since some tumors or portions of tumors retained HLA-ABC and beta 2-microglobulin on their surfaces, the absence of these antigens is not an absolute marker for malignancy.
