Associated comorbidities in psoriasis and inflammatory bowel disease.

BACKGROUND: The association between psoriasis and inflammatory bowel disease (IBD) has been previously reported although a great deal remains unknown about associated comorbidities. OBJECTIVES: The aim of this study was to examine comorbidities in individuals diagnosed with both psoriasis and IBD, and to compare those with individuals diagnosed with psoriasis-only. We also looked at differences within the IBD group by clearly defining that cohort. METHODS: We included 146 patients diagnosed with both psoriasis and IBD and 146 controls diagnosed of psoriasis-only without previous records of IBD, matched by gender, ethnicity and age (±5 years). Patients were obtained from the research patient data repository of Brigham and Women's Hospital (BWH) and Massachusetts General Hospital. Controls were obtained from the psoriatic arthritis and psoriasis follow-up study (PAFS) at BWH. The comparison between the two groups included socio-demographics, comorbidities and laboratory inflammation parameters. RESULTS: Compared to individuals with psoriasis-only, patients with both psoriasis and IBD had significantly higher rates of autoimmune thyroiditis (2.1% vs. 6.8%), hepatitis (0.7 vs. 6.2%) and diabetes (11.0% vs. 26.7%). In addition, of the 146 patients with psoriasis and IBD, 60 (41.1%) were diagnosed with seronegative arthritis. The average C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) of the last visits in our clinics were significantly elevated compared to the individuals with psoriasis-only (ESR, 33.5 vs. 4.0 mm/h; CRP, 9.1 vs. 2.3 mg/L; both P-values <0.0001). CONCLUSIONS: We found that patients with both, psoriasis and IBD have a number of further associated comorbidities, some at significantly higher levels than individuals with psoriasis-only. Common inflammatory pathways and genetic predispositions for specific patterns in the immune response may play an important role in the evolution of associated conditions.

Abnormal hematological indices in cirrhosis.

Abnormalities in hematological indices are frequently encountered in cirrhosis. Multiple causes contribute to the occurrence of hematological abnormalities. Recent studies suggest that the presence of hematological cytopenias is associated with a poor prognosis in cirrhosis. The present article reviews the pathogenesis, incidence, prevalence, clinical significance and treatment of abnormal hematological indices in cirrhosis.

Fine needle aspiration cytology compared with open biopsy histology for the diagnosis of azoospermia.

This was a comparative study to determine the diagnostic value of fine needle aspiration of the testis compared with open testicular biopsy in azoospermic men. A total of 34 infertile, azoospermic patients aged from 26-54 years underwent concurrent testicular fine needle aspiration (FNA) and biopsy. The testis was aspirated at three separated sites (upper, middle and lower pole) using a 20 ml syringe and 21-G butterfly needle. A testicular biopsy was taken from the same sites. Samples obtained from FNA were air-dried and stained with Romanowsky-May-Grunwald-Giemsa method. Sections obtained from testicular biopsy were stained with haematoxylin and eosin (H&E). The patient's history, semen analyses, hormonal profile and testicular volume were analysed, and in addition to the histological results azoospermia was classified into obstructive and non-obstructive. A good correlation between cytological smears and histological sections was found in 65 of 68 testes (95.6%). Normal spermatogenesis was diagnosed in seven patients (20.6%), hypospermatogenesis in nine (26.5%), late maturation arrest in five (14.7%), early maturation arrest in three (8.8%) and Sertoli only-cell in 10 (29.4%) patients. Discordance between cytology and histology was observed in three of 68 testes (4.4%) and was related to inadequacy of FNA. Testicular fine needle aspiration is a simple, minimally-invasive procedure that can diagnose accurately testicular function. In addition to the testicular volume and hormonal status, it can differentiate the obstructive from non-obstructive azoospermia. In cases of non-obstructive azoospermia, multiple passes with a fine needle can be performed instead of open testicular biopsy for sperm extraction if present.
