We report a patient with rectal ulcer with severe stenosis, who underwent urgent surgical treatment for perforated peritonitis.
The 54-year-old man suddenly developed cramping abdominal pain and fever while hospitalized, with signs of peritoneal irritation.
An emergency laparotomy was performed, and severe stenosis of the rectum and a perforated lesion on the oral side approximately
10 cm distant from the stenosis were found, with massive abdominal purulent fluid. He was treated by rectosigmoid colon resection
with transverse colon loop colostomy. Histopathologically, the stenosis was caused by ulceration extending to all muscular
layers of the rectum, with inflammatory changes. Benign rectal stenosis is so rare that differential diagnosis from malignancy
may be difficult when there are inflammatory changes in the surrounding tissues. However, it is necessary to keep in mind
the likelihood of this disease in differentiation from rectal cancer.

Infection with Rhodococcus equi in a patient with sarcoidosis treated with corticosteroids 总被引:5,自引:0,他引:5

A 51-year-old female farmer was diagnosed as having sarcoidosis. During 4 years of observation, slow radiological progression was observed. Cough then developed, necessitating treatment with corticosteroids. After 28 months of continuous treatment with prednisolone in low doses (5-7.5 mg daily), she suffered fever episodes, recurrent haemoptyses, general malaise and loss of weight. A chest roentgenogram showed a left upper lobe infiltrate, which progressed and finally cavitated, and rib destruction. Despite efforts, including a thoracotomy, 22 months passed before a diagnosis could be made. Blood and sputum cultures and cultures from the destroyed rib showed growth of Rhodococcus equi, a common soil organism which can cause infections in foals and other animals. Treatment with rifampicin and erythromycin was successful. R. equi has been reported to cause infection in patients with neoplastic disease and/or immunosuppression, but the disease might be more common than is suggested by the sparse case reports in the literature, owing to lack of familiarity with the organism, which will tend to be overlooked as a contaminant. 相似文献

The aim of our work was to evaluate the inducibility of atrialfibrillation in a group of patients with atrioventricular junctionalreentrant tachycardia and to compare it with that of patientswith a Kent-type ventricular pre-excitation (Wolff-Parkinson-Whitesyndrome) and a control group. One hundred and twenty-five subjects were separated into groups.Group 1 comprised 49 Wolff-Parkinson-White patients, with amean age of 26.4, range 10.66 years; group 2, 51 patients withatrioventricular junctional reentrant tachycardia inducibleby transoesophageal atrial stimulation andlor clinically documented,with a mean age of 43.4, range 1678 years; group 3, 25control subjects with a mean age of2.64, range 1376 years. Each subject underwent atrial transoesophageal stimulation withthe following protocol: programmed atrial stimulation with 1and 2 stimuli during atrial pacing of 100. min1 and 150.min1; atrial stimulation for 10 s at a rate of 200300400500600.min1 with intervals of 10 s between stimulations, fivesuccessive ramp-up atrial stimulations for 9 swith the rate increasing from 100 to 800. min1 with intervalsof 10 s between stimulations. The end point was the completionof the protocol or induction of sustained atrial fibrillation(>1 min). The chi-square test was used for statistical analysis. Our resultsshowed that in group 1 atrial fibrillation was induced in 27149patients (55.1%); this was sustained in 13149 (26.5%) and non-sustainedin 14149 (28.5%); in group 2, atrial fibrillation was inducedin 22151 patients (43.0%); it was sustained in 7151 (13.7%)and non-sustained in 15151 (29.4%); in group 3, sustained atrialfibrillation was not induced in any subject and in only onesubject was a non-sustained atrial fibrillation (4 s) induced. The chi-square test showed that group 2 vs group 1 were non-significant,while group 2 vs group 3 and group 1 vs group 3 were significant(P<0.003 and P<0.0007, respectively). Therefore group 2 patients showed a greater atrial vulnerabilityin comparison to the control subjects and a similar vulnerabilityto group 1 patients. It is possible that the greater atrialvulnerability in the patients of group 2 was due to the doublenodal pathway. 相似文献

A new era in the treatment of systemic lupus erythematosus has dawned with the increasing introduction of monoclonal antibodies and other approaches, that target the key molecules involved in the pathogenesis of the disease. At present the ability to block the CD20 molecule on those B cells that carry this marker has proved the most effective way to treat patients resistant to conventional immunosuppressive drugs. However, these studies have all been open label and the results of double blind controlled studies are eagerly awaited. 相似文献

Communicating with patients with inflammatory bowel disease 总被引:6,自引:0,他引:6
Ulcerative colitis and Crohn's disease, the two main forms of inflammatory bowel disease (IBD), are chronic illnesses that affect hundreds of thousands of Americans. Patients with IBD suffer chronically from diarrhea, abdominal pain, gastrointestinal bleeding, malabsorption, and weight loss requiring continuous medical and surgical attention. Despite recent advances in therapy, IBD follows a course of exacerbations and remissions with approximately 25-50% of patients relapsing annually. Hence, these diseases are readily encountered in primary care and gastroenterology clinics. Though medical and surgical treatment options have improved significantly, little has been written about the psychosocial aspects of IBD. Currently, there is a paucity of data concerning effective communication methods enabling physicians to develop stronger rapport with patients suffering from IBD, the care of whom requires a multidisciplinary approach involving primary care physicians, gastroenterologists, and colorectal surgeons. Because IBD has a high morbidity, it is worthwhile to further investigate those social factors that will improve patients' quality of life. In this paper, we summarize some of the common problems that emerge when taking care of patients with IBD and provide initial guidelines based on the world literature regarding the management and education of patients with IBD. Both primary care physicians and specialists (gastroenterologists, colorectal surgeons) need to be aware of the questions and concerns of IBD patients and to be capable of dispensing the information in a clear and concise manner. Using the case scenario format, we review the most common aspects of communication for health care professionals taking care of IBD patients and suggest ways to establish and maintain long-term doctor-patient relationships. The two most significant interventions that dramatically improve quality of life and patient-physician relationships are proper patient education and appropriate treatment of concurrent depression and anxiety. We hope that our review will form a framework by which different members of the medical team learn their roles in the complex management decisions affecting IBD patients. 相似文献

Hepatotoxicity due to paroxetine, a selective serotonin reuptake inhibitor, is very rare, and to the best of our knowledge, only five cases of liver injury in association with paroxetine have previously been reported in the medical literature. We describe the clinical, biochemical, and pathological findings in a patient with paroxetine hepatotoxicity, which was reversed after withdrawal of the drug. The present case and the others previously reported suggest that hepatotoxicity should be taken into account as a rare complication, sometimes severe, that may occur with paroxetine. 相似文献

Forty-five patients with hypertrophic cardiomyopathy were examined clinically and echocardiographically. The results of their treatment with obsidan and isoptin in relation to various types of central hemodynamic disorders are presented. The data have been obtained making it possible to treat patients differentially with regard to the form of the disease. The treatment of this category of patients requires the echocardiographic monitoring of the parameters of the central hemodynamics and myocardial contractility. 相似文献

Pneumocystis jirovecii pneumonia (PCP) is a potential complication of immunosuppression. Crohn's disease (CD) is an immune granulomatous disorder characterized by transmural inflammation that can affect any part of the gastrointestinal tract. Its treatment is based on steroids and immunosuppressants but in non-responders, biologic compounds such as anti-tumor necrosis factor alpha (TNF) antibodies have been used. Neutralization of TNF causes a decrease in the inflammatory response but increases susceptibility to opportunistic infections such as fungal infections.We report a young male with chronic diarrhea, fever and weight loss who was diagnosed with CD and began conventional treatment with immunosuppressants, but due to lack of response after several weeks, biologic therapy with adalimumab was initiated. Seven weeks later he developed persistent fever and upper respiratory symptoms. After chest CT, bronchoscopy and bronchial lavage, P. jirovecii was identified by silver staining and confirmed by immunofluorescence. To our knowledge this is the second case of pneumocystosis associated with the use of adalimumab in CD and the first reported Mexican case confirmed by microbiological and immunological studies in this setting. 相似文献

Granulomatosis with polyangiitis (GPA), an autoimmune disease characterized by inflammatory granulomas and necrotizing small-vessel vasculitis, primarily affects the respiratory tract and kidneys. Azathioprine (AZA) is a purine analog that is commonly used for maintaining GPA remission after induction therapy with cyclophosphamide. While the dose-dependent side effects of AZA are common and well known, hypersensitivity reactions such as pulmonary toxicity are rare. Here, we describe a case involving a 38-year-old man with GPA-associated pauci-immune crescentic glomerulonephritis who developed subacute hypersensitivity pneumonitis (HP) during AZA maintenance therapy. Five months after the initiation of AZA administration (100 mg/day), the patient was admitted with a 7-day history of cough, dyspnea, and fever. High-resolution computed tomography of the chest showed ill-defined centrilobular nodules and diffuse ground-glass opacities in both lung fields. Bronchoscopy with bronchoalveolar lavage was negative for infectious etiologies. A transbronchial lung biopsy specimen revealed poorly formed non-necrotizing granulomas. A chest radiograph obtained at 2 weeks after discontinuation of AZA showed normal findings. The findings from this case suggest that AZA-induced HP should be considered as a differential diagnosis when a patient with GPA exhibits fresh pulmonary lesions accompanied by respiratory symptoms during AZA therapy. 相似文献

We observed increased ferritin levels in newly diagnosed MDS-RARS patients without transfusional iron-overload. Hence, we hypothesized RARS patients may harbor hemochromatosis-related mutations, which could contribute to the pathophysiology of this myelodysplastic syndromes (MDS) subset. We studied a cohort of 140 MDS patients: 42 with RARS, 10 with increased ringed sideroblasts, and 96 with other forms of MDS (43 RA, 27 RAEB, 17 RAEB-T, 8 MDS/MPD, 1 CMML). Patients were genotyped using restriction fragment length polymorphism, designed to detect C282Y and H63D mutations of the HFE gene. We found significantly higher frequency of heterozygosity for C282Y mutation in RARS patients compared with a large control population of matched race individuals (21 vs. 9.8% in controls, P = 0.03); H63D genotype was not significantly increased. Frequency of HFE variation in other MDS subtypes failed to differ significantly from controls. Within this group, we included patients with a rare form of MDS, provisionally subclassified by WHO as RARS with thrombocytosis (RARSt). 10/14 RARSt patients were carriers of either C282Y or H63D allele significantly increased compared with the combined prevalence in a healthy population (71 vs. 33%, P < 0.01). We found expected distribution of mutant HFE alleles in patients with other forms of MDS (9.1 vs. 9.8%, P = 0.82). Increased prevalence of HFE gene mutations is not a generalized feature of MDS, but some subgroups of MDS, especially those characterized by excessive accumulation of ringed sideroblasts, exhibit C282Y mutations at a higher frequency than in other forms of MDS and healthy controls. 相似文献

Zoledronic acid (ZOL), an intravenous bisphosphonate, has been shown to reduce and delay the incidence of skeletal-related events (SREs) in multiple myeloma (MM) patients with bone disease. A retrospective claims-based analysis was conducted that used two distinct US managed care databases to examine the relationship between persistency with ZOL and clinical benefit. Patients >18 years, diagnosed with MM, and with at least one claim for ZOL (or a claim for malignant bone disease and ZOL initiation within 30 days) between 1/1/2001 and 12/31/2006 were included. Patients were evaluated for incidence of SREs and for mortality. Treatment persistency was defined as the absence of a >45 day gap between ZOL administrations. Of 1,655 patients in this analysis, 1,060 received ZOL and 595 received no intravenous bisphosphonate therapy. Compared with patients not receiving bisphosphonate therapy, ZOL-treated patients had lower incidences of SREs (P < 0.0001) and death (P = 0.0001). Longer persistency with ZOL was associated with lower risks of SREs (P = 0.001), fracture (P = 0.003), and death (P = 0.002) versus shorter persistency. Patients who were persistent with ZOL for ≥1.5 years had an incidence of 15.0 SREs and 6.2 fractures per 100 person-years. Patients who were persistent for 31-90 days had an incidence of 24.6 SREs and 14.0 fractures per 100 person-years, and patients not receiving intravenous bisphosphonates had an incidence of 32.2 SREs and 16.9 fractures per 100 person-years. These data from a real-world setting indicate that among MM patients, longer persistency with ZOL was associated with a lower risk of SREs and fracture. 相似文献
