Abstract
Dysphagia associated with esophageal mechanical obstruction is usually related to malignant esophageal diseases. Benign lesions are rarely a cause for this type of dysphagia, and usually occur either as an intramural tumor or as an extrinsic compression. Mediastinal tuberculous lymphadenitis is rare in adults, and even more rarely causes dysphagia. We report two cases of dysphagia in adult patients caused by mediastinal tuberculous lymphadenitis, presenting radiologically and endoscopically as an esophageal submucosal tumor. Based on the clinical and imaging diagnosis, the patients underwent a right thoracotomy, and excision of the mass attached to and compressing the esophagus. Pathological examination of the specimens showed a chronic granulomatous inflammation with caseous necrosis, which was consistent with tuberculous lymphadenitis.

Abstract
19569 Background: The expression of Erythropoietin (EPO) receptors on cancer cells and the correlation of EPO receptor levels with angiogenesis and progression in some cancers have suggested that EPO could acts directly as an angiogenic factor. The purpose of this study was to assess the effect of treatment with human recombinant erythropoietic agents (rHuEPO) in cancer patients with chemotherapy-induced anaemia on Endoglin and Vascular Endothelial Growth Factor (VEGF) circulating levels as a possible marker of angiogenesis. Methods: Endoglin and VEGF were measured in serum samples from 25 cancer patients with chemotherapy-induced anaemia before and after 3 to 4 weeks of treatment with rHuEPO (Epoetin alfa 150 UI/Kg three times per week; darbepoetin alfa 150 mcg/weekly). A group of 28 healthy voluntaries were used as control. Endoglin and VEGF were analyzed using an ELISA commercial Kit (R&D Systems; Ciudad-Pais). T- student test was used to study the association between variables. Paired comparisons before and after treatment were performed using the Wilcoxon rank-sum test. Results: VEGF serum levels were significantly higher in cancer patients than in controls (476,66±72,56 pg/ml versus 227,34±24,58 pg/ml, p<0.001, respectively). Endoglin levels were significantly higher in patients than controls, although this difference did not reach statistical significance (4.75±0.30ng/ml versus 4.18±0.12 ng/ml, p=0.075). Similar results were found in the different subgroups of patients (Breast cancer, endoglin p=0.019; VEGF p=0.009; Colon cancer, endoglin p=0.084; VEGF p<0.001). Using the Wilcoxon rank-sum test no statistically significant differences in endoglin (p=0.510) and VEGF (p=0.313) serum levels were found between samples obtained before and after treatment with rHuEPO agents. When considering the type of rHuEPO, no differences were observed. In a similar manner, no difference was observed depending on chemotherapy regimen or cancer type. Conclusions: Although the follow up is short and the number of patients is small, our exploratory results do not support that rHuEpo treatment in anaemic cancer patients induce angiogenic serum markers. No significant financial relationships to disclose.

Abstract
Acroangiodermatitis or pseudo-Kaposi sarcoma is an angioproliferative, self-limited entity that includes a group of diseases, congenital or acquired, with cutaneous lesions similar to Kaposi sarcoma (KS). This term can lead to confusion because it comprises several entities that are completely different, nonetheless, it has an important clinical value as it guides the diagnosis and management of these patients. We report the case of a 67-year-old patient with lesions of acroangiodermatitis in both forearms secondary to arteriovenous shunts from hemodialysis. Doppler ultrasound showed a former arteriovenous fistula in addition to the one already known. Immunohistochemical study showed CD34+ staining in endotelial cells and absence of HHV-8 expression.

Abstract
Sweet syndrome is one of the cutaneous processes more frequently associated to systemic diseases. Its association to the systemic inflammatory response syndrome has rarely been described. We report a case of chronic and relapsing Sweet syndrome associated to a chronic and idiopathic systemic inflammatory response syndrome that lasted seven years and proved fatal to the patient. Among the rare cases of Sweet syndrome associated to a systemic inflammatory response syndrome that have been described there have not been any fatal cases as occurred with our patient.

Abstract
INTRODUCTION The constant increase in the incidence of skin cancer together with the requirement for maximum exploitation of available medical resources has meant that dermatological major surgery on an outpatient basis has greatly increased in recent years. OBJECTIVE This article reviews the practice of dermatological surgery in an outpatient setting over a 1-year period. Its purpose is to analyse the number of surgical procedures, the type of cutaneous processes treated and the kind of surgical intervention and anaesthesia used. We also assessed the percentage of cancellations, postsurgical hospital admission and postsurgical complications. Clinicopathological correlation and complete tumour removal were also evaluated. MATERIAL AND METHODS Our clinical experience of major surgery of outpatients at the dermatology department of the Hospital Juan Canalejo in A Coruña (Spain), analysing 565 patients in a non-randomized pilot study running from January to December 2003, is presented. RESULTS Six hundred and forty-four surgical procedures were performed on a total of 565 patients. The three main cutaneous processes treated were basal cell carcinoma (240), squamous cell carcinoma (117) and melanoma (77). The most frequent type of procedure was direct closure (346), followed by exeresis and flap (133) and partial- or full-thickness skin graft (29), nail apparatus surgery (56) and lip surgery (33). Twelve patients were admitted to hospital after surgery owing to the complexity of their operations or to complications arising during surgery. Five hundred and fifty-three patients were discharged after being kept under observation for a few hours. Seventeen patients (3%) suffered complications following surgery, which consisted of partial implant failure (six cases), infection of the surgical wound (six cases), intense pain (four cases) and haemorrhage (one case). There was a good clinicopathological correlation in 90.78% of non-melanoma skin cancers, of which 92.03% were completely removed. CONCLUSIONS Medium and high complexity operations for dermatological processes, traditionally performed on hospitalized patients, can be conducted on an outpatient basis. This allows hospitalization costs and waiting lists to be reduced and affords the possibility of achieving better morbidity rates and medical care than in the standard hospital setting.

Abstract
OBJECTIVE To evaluate the relationship between impedance to flow in the uterine arteries at 22-24 weeks and subsequent spontaneous delivery before 33 weeks. METHODS The pulsatility index (PI) in the uterine arteries was measured by transvaginal sonography at 22-24 weeks in 33,629 women with singleton pregnancies attending for routine antenatal care. The distribution of PI in the 237 patients with live births before 33 weeks, after spontaneous onset of labor, was compared to that in 31,633 patients with live births at or after 33 weeks. RESULTS The median uterine artery mean PI was significantly higher in those women delivering before 33 weeks than in those delivering at or after 33 weeks. The mean PI was 1.57, which is the 95th centile, in 1525 (4.8%) of those delivering at or after 33 weeks and in 19 (8.0%) of the deliveries before 33 weeks. Multiple regression analysis demonstrated that the significant predictors of spontaneous delivery before 33 weeks were ethnic origin, smoking status, previous obstetric history and uterine artery mean PI. However, the prediction of spontaneous early preterm delivery by a combination of maternal characteristics and uterine artery Doppler was not significantly higher than maternal characteristics alone (area under the receiver-operating characteristics curve: 0.704, 95% CI 0.669-0.740 vs. 0.684, 95% CI 0.647-0.722; P = 0.062). CONCLUSIONS Uterine artery PI in spontaneous deliveries before 33 weeks is higher than in those women delivering at or after 33 weeks. However, uterine artery Doppler does not provide a significant improvement in the prediction of spontaneous early delivery provided by maternal demographic characteristics and previous obstetric history.

Abstract
BACKGROUND Gemcitabine is currently considered the standard treatment for advanced pancreatic cancer (APC). Cisplatin and a fluoropyrimidine have some activity in the treatment of this cancer. The aim of this trial is to evaluate the efficacy and toxicity of a fixed dose-rate infusion of gemcitabine associated with cisplatin and UFT in patients with APC. PATIENTS AND METHODS Forty-six chemotherapy-naïve patients with APC that was either unresectable or metastatic were included in this phase II study. All of them had Karnofsky performance status > or =50 and unidimensionally measurable disease. Treatment consisted of gemcitabine 1,200 mg/m2 given as a 120-min infusion weekly for three consecutive weeks, cisplatin 50 mg/m2 on day 1 and oral UFT 400 mg/m2/day (in two to three daily doses) on days 1 to 21; cycles of treatment were given every 28 days. RESULTS A total of 208 cycles of chemotherapy were given with a median of 4 per patient. Fourteen patients (30%) achieved partial responses (95% CI 19-48%) and 17 (37%) had stable disease. The median time to progression was 5 months, and the median overall survival 9 months. Nineteen patients (49%; 95% CI 32-64%) had a clinical benefit response. Grade 3-4 WHO toxicities were as follows: neutropaenia in 26 patients (57%), with 5 cases of febrile neutropaenia (11%), thrombocytopaenia in 15 (33%), anaemia in six (13%), diarrhoea in 5 (11%), asthenia in 2 (4%) and mucositis in 1 (2%). Seven patients required hospitalisation for treatment-related complications. CONCLUSION A fixed dose-rate infusion of gemcitabine associated with cisplatin and UFT is active in patients with APC, though at the cost of considerable toxicity.

Abstract
CONTEXT The clinicopathological characteristics and the molecular features of the follicular variant of papillary thyroid carcinoma (FVPTC) remain controversial. OBJECTIVE/DESIGN/PATIENTS In an attempt to clarify such controversies and to find whether or not FVPTC cases share the molecular features of follicular tumors, we searched for the presence of PAX8-PPARgamma rearrangements, RAS mutations, and RAP-1, RAF-1, and BRAF mutations in a series of 40 FVPTCs as well as in 27 follicular thyroid carcinomas (FTCs) and 12 follicular thyroid adenomas (FTAs). Fluorescence in situ hybridization and RT-PCR were used to detect the PAX8-PPARgamma rearrangement and PCR, single strand confirmational polymorphism, and sequencing for searching the mutations. RESULTS The frequency of PAX8-PPARgamma rearrangement was similar in FVPTCs (37.5%), FTCs (45.5%), and FTAs (33.3%). The same holds true regarding the frequency and type of RAS mutations: FVPTC, 25.0%; FTC, 22.2%; and FTA, 33.3%. BRAF mutations were only detected in FVPTC (10%); the BRAF mutations in these cases (K601E and G474R) are different from the typical BRAF(V600E) mutation of conventional PTCs. No mutations were detected in RAP-1 and RAF-1. In FVPTCs, the PAX8-PPARgamma rearrangement was significantly associated with multifocality and vascular invasion, whereas the RAS mutations were significantly associated with the large tumor size. There were three cases of FVPTC, three FTCs and one FTA, harboring both PAX8-PPARgamma rearrangement and RAS mutations; patients with such tumors were usually very young. CONCLUSIONS We conclude that a subset of FVPTC shares some of the molecular features of follicular tumors. Further studies are necessary to clarify the putative clinical significance (e.g. association to blood-born metastases) of PAX8-PPARgamma rearrangement, RAS mutations, and BRAF(K601E) in FVPTCs.

Abstract
INTRODUCTION Several diseases with follicular occlusion have been described in HIV-infected patients and can appear isolated or associated with each other in an independent disease named 'HIV-associated follicular syndrome'. Worsening of cutaneous lesions during the course of infection in patients with previous acne vulgaris, late onset or severe forms of acne have been reported in HIV-infected patients. PATIENTS AND METHODS A prospective study of 335 HIV-infected patients was performed in our hospital. A meticulous dermatological exploration in all patients was made, and multiple data were stored into a Microsoft Access 97 program. Patients diagnosed as having acne were considered separately, and we studied their characteristics. A statistical analysis with SPSS 9.0 (Statistical Package for the Social Sciences) was performed. RESULTS Thirty-six patients (10.8%) were diagnosed as having acne. Papulopustular lesions were the most frequent clinical presentation. Most lesions were localized on the face or on the back, and 80% of patients had mild to moderate acne; 40% of them required no treatment and the remainder was treated with topical measures, oral antibiotics and isotretinoin. 85% of cases reported the onset of acne during adolescence or before HIV infection and without any relationship with this disease. No relation between acne intensity and stage of HIV infection was observed. A multivariate analysis showed that the most important variable was age. DISCUSSION In contrast to previous reports, no greater intensity or modifications in acne lesions were observed in our HIV-infected patients during the course of the disease. In the majority of cases, cutaneous lesions started before HIV infection, during adolescence, and the most important factor for suffering from acne was young age. In contrast to data reported in the literature, no relation of acne lesions to CD4 lymphocyte count or AIDS case criteria was found in our patients. CONCLUSIONS Acne in HIV-infected patients has characteristics similar to those in non-HIV-infected patients. The age is the most important factor for the appearance of lesions that usually develop during adolescence. Acne lesions are not modified by HIV infection, and no relationship with the severity of HIV infection has been observed.

Abstract
Necrobiotic xanthogranuloma (NXG) with paraproteinemia is a rare non-x histiocytosis with conspicuous lesions mainly located on the periorbital skin. A 68-year-old woman, with a previous history of lymphoplasmacytic lymphoma associated with IgG monoclonal gammopathy over a period of almost 4 years, presented typical lesions of NXG on the periorbital regions and left buttock. Treatment with dioxide carbon laser resulted in great improvement of cutaneous lesions, and no evidence of relapse after a 12-month follow-up. The association of NXG with lymphoplasmacytic lymphoma has not been previously described to our knowledge. The treatment of these lesions represents a true challenge for the clinician and palliative treatment of cutaneous lesions of NXG with CO(2) laser may constitute an alternative treatment in selected cases.

Abstract
The decreased incidence of infectious diseases in developed countries may make their diagnosis difficult. Cutaneous tuberculosis is an example of this fact. A 44-year-old man presented with two painful abscesses on his lower extremities, which developed into chronic ulcers. A cutaneous biopsy revealed necrotizing granulomas in the dermis. Ziehl-Neelsen and periodic acid-Schiff stain were negative. Mantoux test was positive. Tc-99m scintigraphy showed increased uptake in the bone tissue of the left ankle and right tibiae, without direct relation to cutaneous lesions. Chest X-ray showed micronodular, apical, bilateral infiltrates, reduced volume of the right lung, and cavitation of the right superior lobe. Mycobacterium tuberculosis was grown from sputum and skin biopsy samples. Isoniazid, rifampin and pyrazinamide treatment for 2 months, followed by isoniazid and rifampin for 12 months, resulted in complete resolution. The clinical features of cutaneous tuberculosis in our patient were characteristic of tuberculous abscesses. Some uncommon findings, such as the low number of lesions, negative acid-fast resistant stains in cutaneous biopsy samples and his preserved general state of health, may be explained by a higher competence of the immune system than is usual in this clinical subset of disseminated tuberculosis. Cutaneous tuberculosis should be included in the differential diagnosis of cutaneous abscesses in immunocompetent patients.

The purpose of this study was to evaluate the efficacy, assesed as response rate, and toxicity of UFT (Tegafur-Uracil) in combination with oxaliplatin as first-line treatment of advanced colorectal cancer (CRC). In all, 84 patients with recurrent or metastatic CRC with measurable disease were included. Treatment consisted of oxaliplatin 85 mg m−2 in 120-min intravenous (i.v.) infusion on days 1 and 15; i.v. l,leucovorin (l,LV) 250 mg m−2 given in 2 h on day 1, followed by oral UFT 390 mg m−2 on days 1–14, and oral l,LV 7.5 mg/12 h on days 2–14. Cycles were repeated every 28 days. A total of 492 cycles of chemotherapy were delivered with a median of six per patient (range 1–12). There was one complete response (1%) and 28 partial responses (34%) for an overall response rate of 35% (95% confidence interval (CI): 24–46%). A total of 36 patients (44%) had stable disease, whereas 17 (21%) had a progression. The median time to progression was 7.3 months and the median overall survival was 16.8 months. A prescheduled preliminary analysis was performed after inclusion of 16 patients who detected a high gastrointestinal toxicity, which led to a reduction of the UFT dose to 300 mg m−2. With this new dosage, grade 3–4 diarrhoea and grade 3–4 nausea/vomiting dropped to 21 and 14% of patients, respectively. Other grade 3–4 toxicities were stomatitis in one (1%), anaemia in three (5%), neutropenia in two (3%), thrombocytopenia in one(1%), fatigue in six (9%), peripheral sensory neuropathy in nine (14%) and laryngopharyngeal dysesthesia in two patients (2%). The combination of oxaliplatin and UFT–l,LV is an active, easy-to-administer regimen with moderate toxicity. Hence, this regimen is worthy of further investigation.

Abstract
The pathogenetic mechanism of fixed drug eruption (FDE) is still unknown. One of the most common causes of FDE is the use of nonsteroidal antiinflammatory drugs (NSAIDs). Oxicams are in the NSAID group and piroxicam is one of the most used of these drugs. FDE caused by piroxicam is rare but a few cases have been reported. Patch tests are useful for diagnosing some cases of FDE; they give variable results on previously affected skin while no reaction appears on unaffected skin. Some cases of cross-sensitivity among piroxicam and other substances have been reported. We report two new cases of FDE due to piroxicam with negative patch test on normal skin and positive results on affected skin.
