Switching from tacrolimus to sirolimus halts the appearance of new sebaceous neoplasms in Muir-Torre syndrome.

Little is known about the effects of immunosuppression on patients with hereditary nonpolyposis colorectal cancer (HNPCC). We describe a kidney transplant recipient with unrecognized Muir-Torre syndrome in whom the administration of a tacrolimus-based regimen led to the eruption of multiple sebaceous tumors. The patient was later found to harbor an MSH2 mutation. Switching to a sirolimus-based regimen resulted in arrest of the disease. When the patient was switched back to tacrolimus, new facial lesions rapidly appeared. Switching again to sirolimus resulted again in halting the appearance of new lesions. This finding is in line with the known antiangiogenic activity of sirolimus and reports on the regression of cutaneous Kaposi's sarcoma in kidney transplant recipients switched from another immunosuppressive regimen to sirolimus. Further studies on the potential use of sirolimus for the treatment of de novo tumors in immunosuppressed kidney transplant recipients with HNPCC are warranted.

The diagnostic challenge of peritoneal mesothelioma.

The differential diagnosis of diffuse malignant intraabdominal process in women may be a strenuous and long process. We report such a challenging, problematic case of peritoneal mesothelioma and present review of literature in search for best differentiating technique.

Intrapartum spontaneous rupture of liver hemangioma.

A 28-year-old pregnant woman presented at 35 weeks' gestation to obstetric triage with vague abdominal symptoms, stable vital signs and a non-reassuring fetal heart rate. During Cesarean section, intraperitoneal hemorrhage was noted, secondary to spontaneous rupture of a liver hemangioma. We present the perioperative management of a patient with liver hemangioma, along with a review of the literature.

Renal outcome and vascular morbidity in systemic lupus erythematosus (SLE): lack of association with the angiotensin-converting enzyme gene polymorphism.

OBJECTIVES: The angiotensin-converting enzyme (ACE) gene polymorphism has been associated with worse outcome in various chronic glomerular disorders and in hypertension. Because nephritis and vascular morbidity are prominent determinants of outcome in systemic lupus erythematosus (SLE), we studied the distribution and prognostic effect the ACE genotype might have on the outcome of SLE. METHODS: Fifty-six consecutive Israeli SLE patients and 48 (sex and ethnic origin matched) healthy individuals were evaluated for the ACE genotype by a polymerase chain reaction-based assay. The clinical and laboratory parameters of the patients as well as the SLE disease activity index (SLEDAI) and the presence of hypertension, diabetes mellitus, ischemic heart disease, congestive heart failure, and stroke were correlated with the ACE genotype. RESULTS: The distribution of the ACE genotype D/D, D/I, and I/I in the lupus group was 59%, 36%, and 5%, respectively, similar to the distribution in the control group (54%, 31%, and 15%, respectively). We failed to find any significant association between the ACE genotype and disease manifestations, SLEDAI, renal function, or cardiovascular and cerebrovascular morbidity. The clinical and laboratory parameters associated with renal outcome and vascular morbidity in our cohort are described. CONCLUSIONS: No difference was found between the distribution of the ACE genotype in lupus patients and the general population in Israel. Renal function as well as cardiovascular and cerebrovascular morbidity among Israeli patients with SLE are disease-related and independent of the ACE gene polymorphism.

Western immunoblotting of cereal proteins with monoclonal antibodies to wheat gliadin to investigate coeliac disease.

Western immunoblotting was used to investigate the binding of two monoclonal antibodies raised against unfractionated wheat gliadin to different cereal protein fractions separated by SDS-PAGE. Our results confirm the presence of considerable epitope sharing between the gliadin subfractions as well as barley and rye prolamins; however, there was less binding of these antibodies to bands present in oat avenins and maize zeins. The pattern of binding of one of these two antibodies to different cereal prolamins as well as to Frazer's fraction III corresponds closely to the known toxicity of these proteins to patients with coeliac disease.

Detection of wheat gliadin contamination of gluten-free foods by a monoclonal antibody dot immunobinding assay.

Unfractionated wheat gliadin was used to produce murine monoclonal antibodies to gliadin. A dot immunobinding assay, using these antibodies, was developed to detect possible gliadin contamination of nominally gluten-free flour, using dilute ethanol extracts spotted onto nitrocellulose membranes. The sensitivity of the assay was less than 10 micrograms/ml of unfractionated gliadin which permitted the detection of trace amounts of gliadin present in certain wheat starch based 'gluten-free' products. The assay detected not only wheat gliadin, but also prolamine extracts of rye, barley and oats; maize, soya and potato extracts as well as the control proteins casein and ovalbumin, gave negative results. The assay is of value as a simple and rapid method of screening foods for their suitability for consumption by patients with coeliac disease.

Monoclonal antibody ELISA to quantitate wheat gliadin contamination of gluten-free foods.

A sensitive reproducible monoclonal antibody-based sandwich ELISA has been developed to measure the gliadin content of foods. Using the assay we have confirmed that nominally gluten-free products based on wheat starch contain trace amounts of gliadin. The level of gliadin contamination in these foods is sufficient to cause relapse of coeliac disease in specific patients. We have also examined the cross-reactivity of different cereal proteins in the assay and found good correlation with their known toxicity to patients with coeliac disease.

Granulomatous inflammation of the breast in a pregnant woman: report of a case with fine needle aspiration diagnosis.

BACKGROUND: Granulomatous inflammation of the breast is an inflammatory process with multiple etiologies. It can accompany breast carcinoma or be idiopathic. It often presents clinically in a fashion mimicking carcinoma. Idiopathic granulomatous mastitis is strongly associated with lactation and is reported to occur in postpartum patients. This is the second fine needle aspiration (FNA) report of idiopathic granulomatous inflammation in the breast of a pregnant woman. CASE: A 27-year-old, 7-month-pregnant woman presented with a hard nodule in her right breast; on ultrasound examination it showed mixed echogenicity, suspicious for carcinoma. FNA showed granulomatous inflammation. The smears were highly cellular, with many clusters of and single epithelioid cells displaying moderate pleomorphism and prominent nucleoli in a background composed of neutrophils, plasma cells, lymphocytes and multinucleated cells. Core needle biopsy revealed a nonnecrotizing, granulomatous lesion. CONCLUSION: The diagnosis of granulomatous inflammation can be challenging, and the cytologic features can be difficult to separate from those of carcinoma. The relatively rare occurrence of this lesion and its cytologic features make it a potentially difficult diagnosis and diagnostic pitfall.
