Cryoglobulinemia syndrome is a systemic vasculitis that damages mainly small and medium vessels through immune complex deposition. Symptoms of Cryoglobulinemia wax and wane over periods of years, with cutaneous manifestations (palpable purpura), arthritis, arthralgias, and myalgias often worsening with cold exposure. Weakness or asthenia is also present.

THE INCIDENCE OF HEPATITIS C VIRUS INFECTION (HCV) associated with mixed Cryoglobulinemia ranges from 40% to 100%. The hallmarks of Cryoglobulins in HCV infection are that they appear only many years after the initial infection, and that they are mixed. That means that they contain IgM antibodies directed against the Fc portion of IgG, i.e. Rheumatoid Factors (RF) and polyclonal IgG as the antigen.

for q29, i think this is mid-cycle ovulation pain,if pt had her last period 4 days ago and the last time she had the "sharp pain" was 18 days ago and she runs a 28 days cycle then the "sharp pain" occurred on day 14.Also it occurred on either side of the lower abdomen.i.e from the ovary on the side that is shedding the egg for that month and the character of the pain"sharp"
The monthly pain is actually relieved by NSAID. By and large, the pt will benefit from OCP use,which will take care of both types of pain.She should also use condom as OCP will not protect her from STD from her multiple partner.

q13(this is q7 on mine,) i think this is leiomyoma uteri,...dull pressure,worsen during intercourse and menses (+or - menorrhagia).
uterine size is enlarged 14 wks with "IRREGULAR" contour of the fundus.
best test is ultrasound. sonohysterogram will only pick the submucous type.
