RESUMEN
Background: Eosinophilic esophagitis (EoE) is characterized by esophageal dysfunction and, histologically, by eosinophilic inflammation. There is not a clear etiologic treatment. Biopsies analysis using plant histology methods may show callose and pollen tubes in the esophageal mucosa. Component-resolved diagnosis (CRD) with microarrays could detect possible allergens involved and indicate an elimination diet and allergen immunotherapy (AIT). Methods: One hundred and twenty-nine patients with EoE were tested for environmental and food allergens. CRD, histological and botanical analysis were performed. Clinical scores and endoscopic biopsy were performed every six months for three years. Fifty healthy patients, 50 asthmatics due to pollen, and 53 celiac disease patients were included as comparison groups. CRD-directed AIT was administered in 91 EoE patients and elimination diet in 140 patients (87 EoE and all 53 CD patients). Results: CRD detected allergen hypersensitivity in 87.6% of patients with EoE. The predominant allergens were grass group 1 (55%), lipid transfer proteins (LTP) of peach and mugwort, hazelnuts and walnuts. Callose from pollen tubes was found in 65.6% of biopsies. After CRD-guided elimination diet and/or AIT, 101 (78.3%) EoE patients showed significant clinical improvement (p < 0.017) and 97 (75.2%) were discharged (negative biopsy, no symptoms, no medication) without relapse (AU)

AIT-treated patients had better outcomes (odds ratio 177.3, 95% CI 16.2-1939.0). CONCLUSION: CRD-directed AIT and/or elimination diet was efficient in treating EoE patients and was well tolerated.

Cytomegalovirus (CMV) is the most common viral pathogen that negatively affects the outcome of liver transplantation. CMV causes febrile illness often accompanied by bone marrow suppression, and in some cases it invades tissues, including the transplanted allograft. In addition, CMV has been significantly associated with an increased predisposition to allograft rejection, accelerated hepatitis C recurrence, and other opportunistic infections, as well as reduced overall patient and allograft survivals. We carried out a study on a Spanish adult liver transplant recipient who rapidly presented anemia and was diagnosed as having Coomb negative (nonimmune) hemolytic anemia, gastric ulcer, pneumonitis, and cholangitis associated with a CMV infection.

We report a case of intestinal mucormycosis in a 46-year-old male diagnosed with classical Hodgkin's disease, IV-B stage. During the first phase of chemotherapy he had a massive digestive bleeding event secondary to a jejunal ulcer, and zygomicosis mucor-type was diagnosed by endoscopic biopsy. The patient was treated with antifungal drugs and surgical resection of the intestine involved. At surgery a double covered perforation of the jejunum was seen. Pathological examination confirmed the previous diagnosis. After one year of follow-up the patient is doing well, and his lymphoma is on remission. To our best knowledge this is the second case of intestinal mucormycosis in a patient with Hodgkin's lymphoma reported in the medical literature.

Polymorphisms in the promoter region of several cytokine genes have been associated with differential cytokine production. Several reports indicate that polymorphisms in the tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) genes are associated with lipid abnormalities. The aim of this study was to identify the genotype frequencies for -308G/ATNF-alpha and -174G/CIL-6 polymorphisms in Mexican subjects and to determine the influence of both polymorphisms on serum lipid levels. Serum lipid concentrations were measured in 100 healthy Mexican subjects. Screening of the -308G/ATNF-alpha and -174G/CIL-6 polymorphisms was performed in all participants using PCR-RFLPs. Genotype frequency for TNF-alpha polymorphism was: 87% GG and 13% GA, whereas IL-6 polymorphism was: 77% GG and 23% GC. The polymorphism frequencies obtained in this study were significantly different to Caucasian populations. High serum levels of triglycerides and total cholesterol were associated with GG genotype of the -308 TNF-alpha polymorphism, as well as low HDL-c levels, but no association was found between the -174 IL-6 polymorphism and serum lipid concentrations. We observed a significant association of the -308 TNF-alpha polymorphism with lipid profile in Mexican subjects. Furthermore, the genotype distribution of -308 TNF-alpha and -174 IL-6 polymorphisms in Mexican Mestizo population similar to populations in different continents may be due to our genetic background influenced by the mixture of Spaniards, Indian and black genes.

We investigated the effect of beta 3-adrenergic receptor (beta(3)AR) polymorphism on lipid profiles in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) treated with chloroquine. One hundred sixty-eight subjects were classified into three groups: 61 RA patients, 57 SLE patients, and 50 healthy subjects. All patients fulfilled the 1987 and 1982 classification criteria for RA and SLE, respectively, of the American College of Rheumatology. Demographic data and clinical characteristics of the patients were registered. Fasting lipid profile determination and leukocyte genomic DNA isolation from peripheral blood was performed in all the participants. Screening of the beta(3)-AR gene polymorphic region (exon 1) was done by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Quantitative and qualitative variables were analyzed using analysis of variance (ANOVA) with the LSD and chi(2) tests, respectively. An association between the arg64/arg64 beta(3)-AR genotype and high levels of triglycerides (TG) and very low-density lipoprotein cholesterol (VLDL-c) was found in three RA patients ( P=0.01), two of them taking chloroquine. Arg64/arg64 beta(3)-AR polymorphism may contribute to increased TG and VLDL-c in RA patients, independently of chloroquine treatment.

Salivary duct carcinoma is a highly malignant adenocarcinoma of salivary origin. Its pathologic features are distinct from the other salivary gland tumors and bear a remarkable histologic resemblance to ductal breast carcinoma. The clinical course is rapid and the prognosis is dismal. Aggressive therapy is warranted, including primary tumor resection, cervical neck dissection, and radiotherapy. We present a case of salivary duct carcinoma of parotid origin with a very long-term evolution in clear contrast to its supposed aggressiveness. Tumor cells expressed low- and high-molecular-weight cytokeratins, epithelial membrane antigen, carcinoembryonic antigen, and c-erbB-2 but not estrogen and progesterone receptors, actin, and S-100.

OBJECTIVE: To report a case of aggressive inguinal angiomyxoma in a male patient. METHODS: An 82-year-old male patient presented with a well-defined, 6 cm. parafunicular mass in the right groin. The mass was located adjacent to the spermatic cord and had been noted 8 years earlier. Patient evaluation included CT, ultrasound and immunohistochemical studies. RESULTS: The CT and US findings suggested lymph node enlargement. Microscopic analysis showed a myxoid tumor with partially infiltrating margins, vascular channels of small-sized vessels with thick walls occasionally with hyalinization and spindle-shaped or stellate mesenchymal cells with ill-defined margins without atypia or mitosis that were positive for vimentin and negative for actin, desmin, keratins, CD34 and protein S-100. No tumor recurrence or metastasis has been observed at 26-months' follow-up. CONCLUSIONS: To our knowledge, this is one of the few cases of inguinal angiomyxoma in male patients; 16 have been reported to date. This neoplasm appears to originate from pelvic soft tissue fibroblasts.

OBJECTIVE: We review our experience with primary gastric lymphomas type B of low (MALT) and high grade in a population of 366,635 people during 4 years and after performing 9,268 gastroscopies. RESULTS: The incidence of these lymphomas in our medium is similar to that found in the world population. Possible disagreements among the biopsy histology and that of the subsequent gastrectomy samples is pointed out. CONCLUSIONS: The frequency of H. pylori involvement in our primary gastric lymphomas is similar to that reported in the literature for the age of our patients, for the MALT lymphomas an well as for the type B high grade.

We report on two stillborn sisters with generalized hydrops, campomelia, cervical lymphocele, and polycystic dysplasia of kidney, liver, and pancreas. This syndrome conforms to that first described by Cumming et al. [Am. J. Med. Genet. 25:783-790, 1986]. This observation provides additional support for the notion that this syndrome has an autosomal recessive pattern of inheritance.

The authors present the case of a 53-year-old woman suffering from synovial osteochondromatosis of her right elbow responsible for ulnar and median nerve entrapment neuropathy. This condition is characterised by the formation of multiple cartilaginous nodules in the metaplastic synovium of otherwise normal joints, bursae or tendon sheaths. Treatment consisted of partial synovectomy, removal of loose bodies and microscopic nerve release. Synovial osteochondromatosis complicated by nerve compression syndromes has been rarely reported, usually with ulnar tunnel syndrome at the elbow. The literature on this subject is reviewed.

A new case with 14-year follow-up of an extremely rare variety of congenital hand macrodactyly is presented. The disease characteristically presents a diffuse proliferation of fibrofatty tissue, but in this special type, osteocartilaginous deposits around the joints can also be found. The case presented included the troublesome feature of a lipofibromatous hamartoma in the median nerve at the wrist and its branches producing carpal tunnel syndrome. The patient obtained benefit from carpal tunnel release and epineurolysis. The hyperostotic development was managed with conservative resection of the periarticular osteochondromas. The literature reviewed suggests that the hyperostotic cases of macrodactyly do not differ from general cases of this congenital condition, except for the osteochondral deposits. These tumours develop during adulthood or after previous trauma, before epiphyseal closure.

Desmoplastic neurotropic melanoma represents a rare histologic variant of malignant melanoma that is characterized by a proliferation of spindle cells in a densely collagenous stroma with pronounced neurotropism. A 60-year-old man appeared for evaluation of a mass in the lower lip. The labial mucosa was intact, and the lesion had been present for 2 months. The tumor was surgically removed, and after immunohistochemical and ultrastructural analysis it was diagnosed as desmoplastic neurotropic melanoma. The tumor recurred 6 months later, with involvement of the inferior alveolar nerve.

Inflammatory pseudotumor of spleen is an infrequent benign condition. It is difficult to differentiate, on a clinical and radiological basis, from haematologic neoplasms, granulomatous diseases as sarcoidosis and splenic hamartoma. Sometimes can be an incidental finding. Two women, aged 72 years, are presented. On the first case the sympthons mi micked a malignant disease. The second one was an incidental finding in a routine study for cholecystitis. Histological and immunohistochemical study showed a polymorphic cellular population including plasma cell, lymphoid cells, histiocytes, eosinophils and spindle cells, showing a reactive benign character. Plasma cells presented light chains polyclonality. Lymphoid cells were mature and with T inmunophenotype. Spindle cells were focally positive for muscle spe-cific actin and vimentine. In the first case, ultraestructural study showed myofibroblast morphology on the stromal spindle cells. Like many other authors have already postulated, immunohistochemical and ultraestructural findings would corroborate the mesenchymal reactive and benign nature of this type of lesions.
