Pseudoachalasia as a paraneoplastic event in a patient with Hodgkin's disease.

Pseudoachalasia or secondary achalasia (5% of achalasias that are deemed primary achalasias) is an esophageal motor disorder with manometric criteria for achalasia, but it appears in the context of an underlying pathology that can be attributed to its origin. Usually appears in >60 years with rapid evolution of symptoms (<1 year). The main cause of pseudoachalasia is neoformative etiology, but there are others. Our patient started with rapid progression dysphagia and was diagnosed with type II achalasia within a Hodgkin's lymphoma. In the radiological-metabolic studies, disease involvement was ruled out as an extrinsic compression of the esophagogastric junction as well as signs of its activity at this level. Chemotherapy has not been shown to play a role in the development of this pathology. On the other hand, radiotherapy has been associated with an esophageal motor disorder, but, in our case, it was after its onset. Therefore, we propose that the mechanism of pseudoachalasia in our case is a paraneoplastic event. This hypothesis is related to other similar cases reported, and it reflects the importance of continuing to investigate this clinical condition that is indistinguishable by manometry from primary achalasia. In addition, it usually presents differential clinical characteristics whose early recognition has implications for the diagnostic, therapeutic, and prognostic management of the patient.

A study of hospital discharges for venous thromboembolism in the south of Spain. An analysis of 19,170 cases from a regional database from 1998 to 2001.

BACKGROUND: Our objective was to learn about the incidence of hospitalization for venous thromboembolism (VTE) in the public health care system in Andalusia and to define the profile of the patients, with special reference to the Department of Internal Medicine. METHODS: We analyzed the discharged data set of 32 hospitals in the Andalusian Health Care Service between 1998 and 2001, identifying the cases in whom the diagnosis was VTE. The age, sex, length of stay, outcome, number of diagnoses, diagnosis-related group (DRG), and coded procedures were studied. RESULTS: During the period studied, there were 2,228,894 discharges, 19,170 of which involved VTE. In 8494 of these, VTE was the cause of the admission. Some 3961 patients (46.6%) were admitted for pulmonary embolism (PE); 45% were discharged from internal medicine, 41% from pneumology, and 14% from other departments. The average patient age was 65, the length of stay 13.8 days, and the global in-hospital mortality rate 13%. Some 4533 cases (53.4%) were admitted due to deep vein thrombosis (DVT): 38.5% to internal medicine, 21.30% to general surgery, 12.35% to angiology, and the remainder to other departments. The length of stay was 10.6 days with an in-hospital mortality rate of 2.20%. In 7721 cases, VTE was the secondary diagnosis (after excluding 2955 cases of superficial thrombophlebitis of the upper limbs); 74% was associated with a medical DRG. CONCLUSIONS: VTE is a frequent pathology in our hospitals. It shows a great variability in clinical practice although there are differences between patients treated by different specialists. VTE as secondary diagnosis was more frequent in medical inpatients.

Synergism between the brushite and hydroxyapatite urinary crystallization inhibitors.

The aim of this paper is to study possible synergic effects between crystallization-inhibitor molecules of low molecular weight on the hydroxyapatite and brushite crystal nucleation. Kinetic-turbidimetric measurements were performed to follow the nucleation process in synthetic urine at 37 degrees C. Only pyrophosphate + phytate mixture manifested synergic effects on the brushite nucleation, whereas the mixture pyrophosphate + citrate exhibited synergic effects only on the hydroxyapatite nucleation. It seems clear that synergic effects between the crystallization inhibitory capacity of some substances in urine can take place and as a consequence, the high crystallization inhibitory capacity of healthy urine could be assigned not only to the individual inhibitory capacity of each product but also to the synergic effects between different products.

[Autoimmune hemolytic anemia, infrequent complication of ulcerative colitis]. / Anemia hemolítica autoinmune, complicación poco frecuente de la colitis ulcerosa.

Autoimmune hemolytic anemia is a rare complication of ulcerative colitis. A retrospective review of the cases of ulcerative colitis treated at our hospital between January 1984 and August 1993 showed that, among 210 patients, three presented autoimmune hemolytic anemia with a positive direct Coomb's test. They were two men and one woman suffering from a moderately active ulcerative colitis that affected the left colon. The hemolysis was diagnosed before the onset of colitis in two cases and after it in the other. In the only patient treated with sulphasalazine, this drug was stopped without improvement. All the patients were treated with steroids, with resolution of the anemia in one of them. Healing was achieved with splenectomy in the other two. Colectomy was not necessary in any case. After suppression of sulphasalazine and treatment with steroids, the next therapeutic option in patients with ulcerative colitis and autoimmune hemolytic anemia should be splenectomy, whereas colectomy should be only used with unresponsive patients, as well as with those affected by severe ulcerative colitis refractory to steroids. In patients presenting with ulcerative colitis and anemia, the possibility of autoimmune hemolytic anemia has to be considered since--in spite of being rare--it is responsive to proper treatment.
