[Segmental portal hypertension with splenic vein thrombosis caused by pancreatitis].

Background: Splenic vein thrombosis is a complication of pancreatic carcinoma, pancreatitis or pancreatic pseudocyst. It may lead to segmental portal hypertension and bleeding from gastric varices.

Clinical Case: A 31 year-old man was diagnosed with pancreatitis of two weeks of evolution and was referred to our hospital in 2013.

[The first clinical description of granulomatosis with polyangiitis (known before as Wegener's granulomatosis)].

Before 1950, cases of necrotizing vasculitis were commonly published in journals of pathology. Most of these cases were designated as polyarteritis nodosa. In 1952, the pathologist Pearl Zeek critically reviewed and summarized the literature dealing with polyarteritis nodosa and first grouped the different types of necrotizing vasculitis.

[Bouveret's syndrome: A rare presentation of gallstone ileus].

Background: Bouveret's syndrome is defined as gastric outlet obstruction caused by duodenal impaction of a gallstone which passes into the duodenal bulb through a cholecystoduodenal fistula.

Clinical Case: We reported the case of a 46-year-old woman who presented intermittent epigastric pain, nausea, vomiting, and weight loss of 2-months duration. The patient admitted alcohol and methamphetamine abuse.

[B lymphocyte stimulator (BLyS/BAFF) level in sera of patients with lupus].

Background: B lymphocyte stimulator (BLyS/BAFF) is an endogenous protein that plays an important role in the differentiation and maduration of B lymphocytes. Enhanced levels of BLyS have been reported in lupus and other rheumatic diseases.

Methods: Serum samples from 92 lupus patients (94% females, median age 35.

[The golden age of rheumatoid arthritis treatment].

Today, we enjoy the golden age of rheumatology. In the 1970s, the paradigm for treating rheumatoid arthritis consisted in a pyramid. In the decade of the 1980s, and shortly after began a revolution in the understanding and treatment of rheumatic diseases.

[HCV genotypes distribution in HCV infected adulthood patients].

Objective: to determine the distribution of HCV genotypes in a group of HCV infected patients in Mexicali, Mexico.

Methods: a retrospective study which included 66 HCV-infected patients was done. Anti-HCV antibodies were measured by ELISA and were confirmed by the detection of viral RNA in the serum.

[B lymphocyte stimulator in systemic lupus erythematosus].

The B lymphocyte stimulator (BLyS) is an essential protein for the growth and survival of B cells. BLyS is expressed on monocytes, macrophages, and dendritic cells. BLyS binds to three receptors on B cells: BAFF-R, BCMA, and TACI.

[Possible association of gynecological cancer and rheumatoid arthritis].

Background: The association between rheumatoid arthritis and cancer is controversial. Previous studies have shown a correlation between rheumatoid arthritis and the development of lymphoma.

Objective: Describe a case of rheumatoid arthritis and associated breast cancer plus the identification of the clinical features of a set of cases in which arthritis and cancer go along.

[Abnormal cervicovaginal cytology in women with rheumatoid arthritis].

Background: Patients with rheumatoid arthritis (RA) are at increased risk of infections and cancer. A link between RA and abnormal cervicovaginal cytology has rarely been reported.

Objective: The aim of this study was to review cervicovaginal cytology results in women with RA and compare them with a control population.

[Squamous intraepithlelial lesions in women's lupus].

Background: previous studies have suggested an association between systemic lupus erythematosus (SLE), abnormal cervical smears and squamous intraepithelial lesions (SIL), but the underlying cause of this association is not well defined.

Objective: To review Pap smear and biopsy results in SLE women compared with healthy controls and to identify traditional risk factors associated with abnormal smears. Retrospective cohort study.

[Prevalance of antibodies against hepatitis C and B viruses in patients with systemic lupus erythematosus].

Unlabelled: Viruses might be one of the environmental agents that trigger systemic lupus erythematosus (SLE).

Objective: To determine the prevalence of hepatitis C virus (HCV) and hepatitis B virus (HBV) antibodies in patients with SLE.

Methods: We investigated 110 SLE patients (106 women and 4 men, mean age 35.

Influenza vaccination of patients with systemic lupus erythematosus.

Objective: To determine the safety, the immunogenicity, and the increase of pre-existing autoantibodies in patients with systemic lupus erythematosus (SLE) following influenza vaccination.

Patients And Methods: Eighteen women with SLE received an inactivated influenza vaccine. Antibody titers were measured before and 4 weeks after vaccination using a standardized hemagglutination inhibition (HAI) assay.
