140 cases of macroprolactinemia: selected clinical and technical laboratory aspects

CLINICAL ASPECTS OF SPINAL CORD MENINGIOMAS: ANALYSIS OF FORTY CASES

A retrospective analysis was performed on forty cases of spinal cord meningiomas, operated on at Dr. Shariati Hospital from 1976 to 1990. Age and sex distribution, clinical presentation and tumor location were comparable to those reported by others. In males the tumors were distributed evenly in cervical and dorsal areas and were often anterior to the cord. This finding makes a different s...

Selected laboratory aspects of influenza surveillance.

The importance of virologically documented infections in influenza surveillance is well recognized and has been reaffirmed in recent reviews. The large number of specimens tested in surveillance make efficiency and low cost of virologic methods important. Based on observations made by others and our work with reisolation of stored specimens we have used the continuous line tissue cultures MDCK ...

Clinical and technical aspects of blood administration

Introduction Errors in pretransfusion specimen collection, omission of appropriate transfusion filters, or co-administration of incompatible fluids with blood products could transform blood transfusion from a lifesaving measure into a life threatening event. In this chapter, we will summarize key aspects of blood component administration, with an emphasis on processes and technologic advances t...

Macroprolactinemia: Diagnostic, Clinical, and Pathogenic Significance

Macroprolactinemia is characterized by a large molecular mass of PRL (macroprolactin) as the main molecular form of PRL in sera, the frequent elevation of serum PRL (hyperprolactinemia), and the lack of symptoms. Macroprolactin is largely a complex of PRL with immunoglobulin G (IgG), especially anti-PRL autoantibodies. The prevalence of macroprolactinemia is 10-25% in patients with hyperprolact...

Clinical NMR imaging of the brain: 140 cases.

Cranial nuclear magnetic resonance (NMR) scans were performed on 13 healthy volunteers and 140 patients with a broad spectrum of neurologic disease and compared with x-ray computed tomography (CT) scans. The NMR scans included a variety of sequences reflecting proton density, blood flow, T1, and T2 as well as transverse, sagittal, and coronal images. White matter, gray matter, and cerebrospinal...
