Enterocutaneous fistulas and Crohn´s disease: clinical characteristics and response to treatment.

INTRODUCTION: the low prevalence of enterocutaneous fistulas (ECF) in patients with Crohn´s disease (CD) justifies the scarcity of studies that analyze the effect of medical treatment and the need for surgery in these patients. The objective of this study was to evaluate the clinical characteristics of patients with CD who have ECF and the response to different treatments. MATERIALS AND METHODS: patients with CD who presented ECF fistula between 1970 and 2009 in three tertiary centers in Spain were analyzed retrospectively for their clinical characteristics, response to treatment as well as the correlation between the response to biological therapies for ECF and perianal disease. The inflammatory activity of the disease was measured using the Harvey-Bradshaw index. The definitions of partial or complete response were based on the treating physician´s judgment. RESULTS: twenty six patients were included (18 women); in more than half of cases (67%), anti-TNF treatment improved fistula drainage. Postoperative fistulas responded better to anti-TNF treatment than did spontaneous fistulas (80 versus 57%). One hundred percent and 60% of spontaneous and postoperative fistulas closed after surgery, respectively. CONCLUSIONS: although the majority of patients required surgery as the ultimate treatment, anti-TNF drugs improved fistula output in an acceptable percentage of patients who were treated. Therefore, this may be a treatment strategy prior to surgery in a select group of patients.

[Gastric adenocarcinoma in young adults; comparative study with older patients]. / Adenocarcinoma gástrico en adultos jóvenes; estudio comparativo con pacientes mayores.

BACKGROUND: Gastric adenocarcinoma (GA) has been considered a disease of elderly age and has been rarely reported in patients younger than 35 years of age. The aim of thisΩ demographic, clinicopathological and prognosis of gastric cancer in young patients and to compare their features with the behavior in elder adults. METHODS: Between 1993 and 2008, 1536 patients with GA were enrolled in a retrospective database. Clinical and pathologic features of thirty patients aged 35 years or less (young group) were compared with those of 458 aged 75 years or more (elder group). RESULTS: Mean patient age was 31 and 80-years old in the young and elder groups, respectively, with a predominance of females in the last group (61%). Lauren diffuse type carcinoma was more frequent in people younger than 35 years (70%) than in older patients (17.4%). Main symptoms were dyspepsia (40%) and hemorrhage (20%). The most common T stage in young and elder patients was T3 (52.9% and 56.7% respectively). Surgical resection was performed in 68% of cases and the rest received only systemic chemotherapy. CONCLUSION: Gastric adenocarcinoma is rare in young patients and most cases presented at advanced clinical stage similar to elderly patients, so the prognosis in both age groups is poor. For this reason is important to be aware of alarm symptoms and risk factors in order to perform an early endoscopic diagnosis and a treatment with curative intent.

Acute spontaneous tumor lysis syndrome in a patient with Crohn's disease taking immunosuppressants.

Acute tumour lysis syndrome (TLS) is a catastrophic complication of the treatment of certain neoplastic disorders. It most commonly occurs in association with hematologic malignancies and appears a few hours to a few days after initiation of specific chemotherapy, as the result from the release of intracellular components into the bloodstream due to abrupt malignant cell death. Acute spontaneous TLS is rare, and it has been described in leukemia and lymphoma and in some patients with solid tumors prior to institution of therapy. The syndrome is characterized by hyperuricemia, hyperphosphatemia, hypocalcemia, hyperkalemia, and acute oliguric or anuric renal failure due to uric acid precipitation within the tubules (acute uric acid nephropathy) and to calcium phosphate deposition in the renal parenchyma and vessels.We report a case of acute spontaneous TLS in a patient with Crohn s disease treated with immunosuppressive drugs, who developed a plasmocytoma, in which serum uric acid concentration attained exceptionally high levels (44 mg/dL). The patient underwent acute oliguric renal failure, which required treatment with hyperhydration, urine alkalinization, urate oxidase and hemodialysis, with a fatal evolution.In conclusion, the present case report has several peculiarities: that of being one of the rare examples of spontaneous TLS, that of showing an exceptionally severe hyperuricemia, probably the highest ever reported in the literature, and that of the possible increased risk of tumours in patients with Crohn s disease taking inmunosuppressives and/or TNF antagonists.

Brain metastases as the first sign of colon cancer.

Cerebral metastases from colorectal cancer occur in 8% of cases. Diagnosis is usually made when primary disease and widespread metastases are already known. However, the detection of brain metastases as the first sign of colorectal carcinoma without any liver and/or lung involvement is extremely rare. Central nervous system metastases are more commonly seen in rectal cancer and often occur concurrently with lung metastasis. We report a case of a patient with brain metastases as the first clinical manifestation of an adenocarcinoma of caecum without any other organ involvement.

Eosinophilic esophagitis in adults, an emerging cause of dysphagia. Description of 9 cases.

BACKGROUND: Eosinophilic esophagitis is a rare condition mainly affecting children, although the number of cases reported in adults is on the increase. It is characterized by intense infiltration of eosinophilic leukocytes in the esophageal mucosa, without involvement of other sections of the alimentary canal. MATERIAL AND METHODS: Over the past year, following the performance of endoscopies and biopsies, our service identified nine patients who were diagnosed with suffering from this disorder. Each patient sought medical help for episodes of long-term, self-limited dysphagia or food impaction in the alimentary canal. RESULTS: Endoscopy revealed esophageal stenosis in the form of simultaneous contraction rings or regular stenosis. In six cases, the manometric study showed a nonspecific motor disorder of severe intensity affecting the esophageal body, and another patient had a disorder characterized by the presence of simultaneous waves and secondary peristaltic waves in the three thirds of the organ. These disorders are presumably due to eosinophilic infiltration of the muscular layer or ganglionar cells of the esophagus, and account for symptoms in these patients. Although the etiopathogenesis of this illness is uncertain, it is clearly an immunoallergic manifestation. CONCLUSIONS: As the number of diagnosed cases is on the increase, eosinophilic esophagitis is in adults a specific entity within the differential diagnosis of dysphagia in young males with a history of allergies. Eosiniphilic esophagitis responds in a different number of ways to therapies used. We successfully used fluticasone propionate, a synthetic corticoid applied topically, which proved to be efficient in the treatment of this illness by acting on the pathophysiological basis of the process. It does not have any adverse effects, thus offering advantages over other therapies such as systematic corticoids or endoscopic dilations.

Síndrome de lisis tumoral “espontáneo” en paciente con enfermedad de Crohn tratado con inmunosupresores / Acute spontaneous tumor lysis syndrome in a patient with Crohn's disease taking immunosuppressants

El síndrome de lisis tumoral (SLT) es una complicación catastrófica del tratamiento de ciertas enfermedades neoplásicas. Si bien es más frecuente en pacientes con neoplasias hematológicas malignas tras el inicio de la quimioterapia, puede presentarse excepcionalmente, tras la necrosis espontánea de algunos tumores, en ausencia de tratamiento citostático. Clínicamente cursa con hiperuricemia, hiperfosfatemia, hipocalcemia, hiperpotasemia y fallo renal agudo. Presentamos el caso de un paciente con enfermedad de Crohn en tratamiento inmunospresor, que desarrolló un síndrome de lisis tumoral espontáneo como debut de un plasmocitoma. Al ingreso, se objetivó un fracaso renal oligoanúrico que, a pesar de tratamiento precoz con hiperhidratación, alcalinización de la orina, urato-oxidasa y hemodiálisis, tuvo un desenlace fatal en 72 horas. Este caso reviste un interés particular por lo excepcional de la naturaleza "espontánea" del síndrome de lisis tumoral en ausencia de quimioterapia, por presentarse con una hiperuricemia extrema, probablemente la más alta de las recogidas en la literatura, y por la controversia actual de la terapia con inmunosupresores y/o biológicos en la enfermedad inflamatoria intestinal y su relación con el desarrollo de determinados tumores(AU)

Esofagitis eosinofílica del adulto, causa emergente de disfagia. Presentación de 9 casos / Eosinophilic esophagitis in adults, an emerging cause of dysphagia. Description of 9 cases

Introducción: la esofagitis eosinofílica es una enfermedad poco frecuente, propia de la edad pediátrica, aunque cada vez son más los casos descritos en pacientes adultos. Se caracteriza por la intensa infiltración de la mucosa esofágica por leucocitos eosinófilos, en ausencia de afectación de otros tramos del tubo digestivo. Material y métodos: en nuestro servicio hemos identificado durante el último año a 9 pacientes que fueron diagnosticados de esta entidad tras la endoscopia y toma de biopsias. Todos consultaron por episodios de disfagia autolimitada de larga evolución o por impactación de alimento en esófago. En la endoscopia se observaron estenosis esofágicas, en forma de anillos de contracción simultánea o estenosis regulares. Resultados: el estudio con manometría esofágica demostró la existencia de un trastorno motor de cuerpo esofágico de tipo inespecífico e intensidad severa en 6 casos, y en otro paciente un trastorno caracterizado por la presencia de ondas simultáneas en los tres tercios del órgano y ondas secundarias peristálticas. Dichos trastornos son debidos presumiblemente a la infiltración eosinofílica de la capa muscular o de las células ganglionares del esófago, y justifican los síntomas de estos pacientes. Conclusiones: aunque la etiopatogenia de la enfermedad no es bien conocida, parece claro que se trata de una manifestación inmunoalérgica. Su prevalencia diagnóstica está en aumento, por lo que la esofagitis eosinofílica del adulto es una entidad específica en el diagnóstico diferencial de la disfagia en varones jóvenes con antecedentes de alergia. La esofagitis eosinofílica presenta una respuesta variable a las terapias utilizadas. Nosotros hemos utilizado con éxito el propionato de fluticasona, un corticoide sintético de aplicación tópica, eficaz en el tratamiento de esta entidad al actuar sobre la base fisiopatológica del proceso. Carece de efectos adversos, por lo que presenta ventajas frente a otras terapias como los corticiodes sistémicos o las dilataciones endoscópicas

Cirrhosis-like radiological pattern in patients with breast cancer

INTRODUCTION: Hepatic toxicity of breast cancer therapy is well known, usually consisting of elevation in the serum levels of hepatic enzymes or fatty infiltration of the liver. The chemotherapeutic agents most commonly linked to hepatotoxic effects are methotrexate, anthracyclines, taxanes and cyclophosphamide. There are few reports of patients with liver metastasis having radiological findings mimicking cirrhosis, both in the presence or the absence of prior systemic chemotherapy. Hepatotoxicity of antineoplastic drugs and cellular necrosis induced by response of liver metastases to chemotherapy may play a critical role in its physiopathology. MATERIALS AND METHODS: This article reports a series of ten women with breast cancer (nine with liver metastasis) treated with chemotherapy or hormonotherapy. RESULTS: They had low risk factors for hepatic disease, but developed a cirrhosis-like appearance in the computed tomography scan. The patient without liver metastasis is the second of this kind described in the literature. Relatively few reports have documented clinical sequelae of portal hypertension. In our series, three patients had oesophageal bleeding varices needing be hospitalised. To our knowledge, these are the first cases reported in the literature. CONCLUSIONS: This suggests that some manifestations of portal hypertension may develop in association with the cirrhosis- like pattern induced by breast cancer therapy (AU)

Radiofrequency ablation for hepatocellular carcinoma and liver metastases: experience in Hospital La Paz

INTRODUCTION: Radiofrequency ablation for patients presenting with non-resectable primary or metastatic liver tumours seems to be a valid therapeutic alternative. In the present study, we show a descriptive list of indications, results and complications of Radiofrequency Ablation Technique for treating non-resectable solid hepatic tumours. MATERIALS AND METHODS: Twenty two patients were included in this study; eleven of them (50%) sustained liver metastases from colorectal adenocarcinoma, ten patients (45.5%) had hepatocellular carcinoma and 1 patient had insulinoma. RESULTS: Local recurrence rate of hepatocellular carcinoma was 22.7% and 27.3% for colorectal carcinoma, after a respective median follow-up of 21 and 14 months. Complications rate was 6.9% and technique-associated mortality rate was 0%. CONCLUSIONS: Radiofrequency ablation is an easy to make, safe and useful technique for the treatment of primary and metastatic liver tumours (AU)
