Can patients with symptomatic Tarlov cysts be differentiated from patients with specific low back pain based on comprehensive history taking?

Background: Tarlov cysts (TCs) are expanded nerve root sheaths that occur near the dorsal root ganglion and result from increased intraspinal hydrostatic pressure. TCs most frequently affect the lumbosacral plexus and therefore may cause specific symptoms such as perineal pain and neurogenic bladder, bowel, and sphincter problems. It has been estimated that 1% of the population has symptomatic Tarlov cysts (STCs).

The status of the species Pectinatus portalensis Gonzalez et al. 2005. Request for an Opinion.

On the basis of 16S rRNA gene sequence analysis and several key phenotypic features, it was ascertained that the cultures cited as the type strain of the species Pectinatus portalensis, CECT 5841(T) and LMG 22865(T), do not conform to the description, [Gonzalez, J. M., Jurado, V.

An unusual evolution of the serum CA 125 level in a ovarian cancer patient.

The usefulness of serum CA 125 measurements in monitoring ovarian cancer has been firmly established in recent years. The CA 125 levels correlate well with tumor status, have a predictive value for second-look operations, indicate responsiveness to chemotherapy, and are a strong independent prognostic factor for survival. We report here a patient with an unusual evolution of the CA 125.
