Ulcerative colitis associated with Weber-Christian panniculitis and musculitis: a case report

A case of 22-year-old man suffering from ulcerative colitis, in whom Weber-Christian panniculitis and musculitis occurred simultaneously, is reported. He had suffered from ulcerative colitis for 7 years and he again had bloody stools 1 month before being admitted. Two weeks before admission, large (2-4 cm) subcutaneous tumors appeared. Weber-Christian panniculitis, musculitis, and active stage ulcerative colitis were diagnosed. All the symptoms went into remission after steroid therapy. The possibility of the existence of a common antigen in enterobacterial wall, colonic epithelium, and adipose tissue was suggested.     

Ulcerative colitis as a primary manifestation of Churg-Strauss syndrome

A 29-year-old woman with chronic bronchial asthma and inflammatory bowel disease, previously classified as idiopathic, was hospitalized because of bouts of fever and increasing dyspnoea and diarrhoea. Chest radiograph showed extensive bilateral pulmonary infiltrates. Thought to be suffering from bacterial pneumonia she was treated with broad-spectrum antibiotic, but without improvement even after a change of antibiotics. Numerous diagnostic tests failed to find any causative organism. Subsequently she was found to have peripheral eosinophilia and pericardial effusion associated with echocardiographic and electrocardiographic signs of myocarditis, which raised the suspicion of allergic granulomatous vasculitis (Churg-Strauss syndrome). The patient's acute illness contraindicated a lung biopsy, but the clinical picture left no doubt of the true diagnosis. Treatment with methylprednisolone (initially 250 mg, then 80 mg daily) rapidly improved the clinical, radiological and biochemical findings. But four months later, under maintenance treatment with 15 mg methylprednisolone daily, she experienced another bout of colitis and, a few days later, pulmonary recurrence of the Churg-Strauss syndrome, both clinically and radiologically. The dose of methylprednisolone was raised to 60 mg daily. The inflammatory bowel disease, endoscopically manifesting as ulcerative colitis, was most likely part of the systemic vasculitis.-This case demonstrates that colitis can be the primary manifestation of Churg-Strauss syndrome.     

Ulcerative colitis is as common in Crete as in northern Europe: a 5-year prospective study

A DNA ligase-encoding gene (Ca CDC9) was cloned from Candida albicans by complementation of an ime-1 mutation in Saccharomyces cerevisiae. In this system, IME1 function was assayed using a S. cerevisiae strain with a ime2-promoter-lacZ gene fusion such that following transformation with a C. albicans genomic library, the presence of positive clones was indicated upon the addition of X-gal to sporulation media. Transforming fragments were subcloned in pGEM7 and sequenced. Sequence homology with several ATP-dependent DNA ligases from viruses, fission yeast, human, baker yeast and bacteria was observed.     

Ulcerative colitis: patterns of involvement in colorectal biopsies and changes with time

Chronic inflammation, both endoscopic and histologic, in a contiguous and symmetric distribution is said to be important in distinguishing ulcerative colitis (UC) from Crohn's disease. Little is known whether this rule holds during the course of the disease and whether endoscopic/histologic correlation persists. In this study, we analyzed histologic patterns of UC in sequential sets of biopsy specimens to assess whether endoscopic and histologic findings correlate with time and treatment and to see whether distribution changes. Two hundred seventeen sets of colorectal biopsy specimens from 797 sites from 41 patients with clinical UC were studied and correlated with endoscopic findings. Each biopsy specimen was classified as definite or suspicious for chronic colitis or normal. Two histologic patterns of disease were identified: (1) diffuse, when all areas in all pieces from a biopsy segment had clear-cut colitis and (2) nondiffuse, when not all pieces were involved or single pieces had disease and normal mucosa both. Of 41 patients, the maximal extent of histologic disease was pancolitis in 30; 25 had less extensive disease at some point in the course. The maximal extent was left-sided in eight patients, seven of whom had less extent at some point. Of the three patients in whom the maximal extent was proctosigmoiditis, in one the inflammation disappeared. Seventy percent of the biopsy sites had diffuse patterns and 30% had nondiffuse. Histologic and endoscopic disease reverted to normal in 22 and 24 of 41 patients, respectively. Endoscopic and histologic findings were similar in 65% of the biopsy sites. Our results indicate that in long-standing UC (1) histologic disease may revert to normal mucosa, (2) because endoscopy alone may be insufficient to identify the mucosa as normal, biopsies should also be performed on the endoscopically normal mucosa, (3) the full extent of UC often is not established by a single set of biopsies, and (4) nondiffuse chronic inflammation and rectal sparing occurs in UC and are not necessarily markers of Crohn's disease.     

Ulcerative colitis: from medical management to ileal pouch anal anastomosis: a patient's perspective

Ulcerative colitis (UC) is a chronic disease that may require extensive medical and, at times, surgical intervention. Patients with UC are encouraged to form a multidisciplinary healthcare team to provide the support needed to cope with this chronic, debilitating illness. In this article, the authors provide the personal perspective of a patient coping with UC, the role of the gastroenterology nurse, and the viewpoints of key members of the healthcare team. Tracing the course of the disease from onset to medical management and then surgery, the authors relate the process by which the patient interacted with the healthcare team to reach the decision for seeking a surgical solution to the disease and how the patient coped with the rare but extended complications of surgery. The patient's decision illustrates the importance of her perspective and the varying roles played by the healthcare team. Medical management of UC and the technical aspects of ileal pouch anal anastomosis surgery are discussed.     

Ulcerative colitis with overexpression of p53 preceding overt histological abnormalities of the epithelium

Laser-induced fluorescence of pheophorbide a (Ph-a) was used for in vitro photodynamic imaging (PDI) of a rat pancreatic acinar tumor. A 400 nm excitation induced a 470 nm autofluorescence and a 678 nm dye fluorescence in tumors and their surrounding pancreas 24 h after a 9 mg kg-1 body weight Ph-a intravenous administration. With lower intensities in these blood-rich tumors than in pancreas, Ph-a fluorescence signals are unable to provide tumor images. A dimensionless function (the ratio of Ph-a fluorescence by autofluorescence, called Rt for the tumor and Rp for the pancreas) was used for fluorescence contrast calculation (C = Rt/Rp) between six tumors and their paired pancreas. Among five available laser excitation wave-lengths, only the 355 nm excitation gave a distinctive contrast (C = 1.5). The PDI of six intrapancreatic tumors and their intraperitoneal metastasis and of two control normal pancreas was thus performed ex vivo using a 355 nm excitation source delivered by a tripled Nd:YAG laser and a charged-coupled device camera. Fluorescence images were recorded at 680 nm (dye), 640 nm (background) and 470 nm (autofluorescence) through three corresponding 10 nm width bandpass filters. Computed division for each pixel of Ph-a fluorescence values by autofluorescence generated false color image. In this way, contrasted tumor images were obtained. But in five out of six animals false-positive images were present due to an autofluorescence decrease in some normal pancreatic areas. A 470 nm autofluorescence imaging on the same tumors gave in all cases false-positive image and false-negative in half of the cases. These observations suggest that autofluorescence alone is unable to achieve accurate PDI of pancreatic carcinoma and that using Ph-a as a PDI dye needs strong improvements.     

High caloric parenteral nutrition in patients with mouth and oropharyngeal cancers--a clinical study

Patients with carcinomas of the oral cavity and oropharynx often show signs of malnutrition. This is caused by reduced intake in patients due to chronic alcoholism resulting in suppressed appetite and disturbed gastrointestinal functions. Also the growth of the tumor can cause painful swallowing. The effects of chronic malnutrition reduce patients tolerance regarding surgical treatment, chemotherapy and radiation. A pretherapeutic parenteral balanced nutrition should achieve an anabolic metabolism. Changes in body cell mass (bcm) as a parameter of total protein synthesis can be estimated by bioelectrical impedance analysis in order to prove the success of this management. Twenty-eight patients participated in this study, divided into three groups: group 1 = 18 male subjects and group 3 = 3 female subjects, all able to be operated upon, and group 2 = 7 male subjects, not able to be operated. High caloric nutrition in group 1 lead to a higher increase of bcm than in group 2. The review of single cases showed that in both groups one part of the patients failed increasing bcm despite nutrition. The therapeutic response was correlated to survival by means of a Kaplan-Meier analysis and a Cox-model. Survival probability could positively be correlated to an increased bcm.     

Cytogenetic analysis of several pseudomyxoma peritonei lesions originating from a mucinous cystadenoma of the appendix

BACKGROUND: Reports of endovascular stent infection have recently been described. The purpose of this study was to determine if intravascular metallic stents in a swine model could become infected following a bacterial challenge given remote from the time of stent placement. METHODS: Balloon expandable metallic stents (Palmaz) were implanted in the iliac arteries of 14 swine. An angioplasty, without stent placement, was also performed in the contralateral iliac artery. An intravenous bacterial challenge with Staphylococcus aureus was given 4 weeks after stent placement. Euthanasia was performed 72 hours after the bacterial challenge. At the time of euthanasia, the iliac artery/stent complex and the contralateral angioplastied iliac artery were harvested and sent for microbiologic and pathologic analysis. RESULTS: Seven of the 14 stent/artery complexes were culture positive for S aureus whereas only one of the 14 angioplastied arteries was positive for S aureus (P = 0.03). On histologic examination, 6 of the 14 stent/artery complexes had evidence of acute inflammatory changes in the arterial wall. This compares with only 1 of 14 angioplastied arteries having evidence of inflammatory infiltrate in the arterial wall (P = 0.07). All 6 of the stent/artery complexes with inflammatory infiltrate were culture positive. CONCLUSION: In the swine model, intravascular metallic stents have the potential to become infected when a bacterial challenge is given 4 weeks after stent placement. Further studies evaluating the incidence of stent infections in humans are needed.     

Treatment of ulcerative colitis with germinated barley foodstuff feeding: a pilot study

OBJECTIVE: To determine the extent of glucocorticoid counter-regulatory control in the slimming action of oleoylestrone. DESIGN: Control and adrenalectomized rats were subjected to a seven-day treatment with 3.5 micromol/kg/d oleoylestrone in liposomes injected i.v. continuously by implanted osmotic minipumps. SUBJECTS: Sham-operated control and adrenalectomized lean Zucker rats. MEASUREMENTS: Body weight and food intake; plasma glucose, urea, insulin, leptin and corticosterone; liver glycogen. RESULTS: Treatment with oleoyl-estrone resulted in decreases in body weight and in food intake, as well as in circulating glucose, insulin and leptin. Combined adrenalectomy and oleoyl-estrone treatment resulted in a loss of almost 15% body weight in only seven days, with a severe drop in circulating glucose and insulin, almost total disappearance of plasma leptin and liver glycogen and a 3-fold rise in circulating urea. Food intake decreased sharply, which resulted in the exhaustion of energy reserves. CONCLUSION: The results presented here, strongly support the hypothesis that glucocorticoids play an important role in the modulation of oleoyl-estrone-induced imbalance of energy intake and expenditure. The large effect of oleoyl-estrone on glucose, glycogen- and protein-derived (urea levels) energy in adrenalectomized rats, provides more evidence for the assumed protective role of glucocorticoids against the oleoyl-estrone-induced net loss of energy reserves. The results also show the powerful destabilizing effects of unchecked oleoyl-estrone on energy balance.     

SLAP lesions: a retrospective multicenter study

This study was performed to assess the relationship between the level and extent of prostatic capsular invasion (PCI) by cancer and the clinical and pathological features and prognosis of early-stage prostate cancer. We conducted a retrospective analysis of the clinical (age, stage, grade, prostate specific antigen [PSA] level) and pathological (tumor volume, stage, grade, surgical margins) features of 688 patients treated with radical prostatectomy to determine the pathological features and probability of recurrence associated with various levels of PCI. Radical prostatectomy specimens were serially sectioned and examined by whole-mount technique. Progression-free probabilities (PFP) after radical prostatectomy were determined by Kaplan-Meier and Cox proportional hazards regression analysis. Progression was defined as a rising serum PSA < or = 0.4 ng/mL or clinical evidence of recurrent cancer. Increasing clinical stage, Gleason grade in the biopsy specimen, and pretreatment serum PSA levels were each associated with increasing levels of PCI (P < .001). In the radical prostatectomy specimen, increasing levels of PCI were significantly associated with increasing tumor volume (P < .001), Gleason grade (P < .0001), seminal vesicle involvement (SVI, P < .001) and lymph node metastases (+LN, P < .001). None of 138 patients without capsular invasion had SVI or lymph node metastases (+LN), and all remained free of progression, even though some had large volume (up to 6.26 cm3) or poorly differentiated (Gleason sum up to 8) cancers. Invasion into the capsule (n = 271) was occasionally associated with SVI (6%) or +LN (3%) and a significantly (log-rank test) lower PFP of 87% at 5 years. Focal and extensive extraprostatic extension (EPE) were associated with progressively increased risk of SVI and +LN and lower PFP (73% and 42%, respectively). In a multivariate analysis, the level of PCI was an independent prognostic factor (P < .001). There is a strong association between the level of invasion of cancer into or through the prostatic capsule and the volume, grade, pathological stage, and rate of recurrence after radical prostatectomy. Prostate cancer does not appear to metastasize in the absence of invasion into the capsule regardless of the volume or grade of the intracapsular tumor. Subclassification of patients according to the levels of PCI provides valuable prognostic information.     

p53 expression in ulcerative colitis: a longitudinal study

p53 Mutation is a late event in the development of sporadic colorectal carcinoma (CRC). The timing of p53 mutations in the development of ulcerative colitis associated colorectal carcinoma (UCACRC) is, however, less certain and some reports suggest that it may be a relatively early event. This study sought to establish the timing of p53 mutations in neoplasia arising in ulcerative colitis. Blocks of 10 resected colorectal specimens from patients who had had a biopsy positive for dysplasia at least one year prior to resection were retrieved from the archives of St Mark's Hospital. Immunochemistry using the monoclonal antibody DO-7, specific for both mutant and wild type p53, was performed on sections from both the resection specimens and dysplastic biopsy specimens. Seven of the 10 resection specimens were positive for p53. Two of these seven specimens showed p53 overexpression in specimens taken two years before the development of carcinoma or high grade dysplasia. Five of the seven specimens were negative for p53 overexpression between one and four years prior to resection. These results suggest that p53 overexpression is usually a late event in the development of UCACRCs.     

Long-term treatment of ulcerative colitis with ciprofloxacin: a prospective, double-blind, placebo-controlled study

BACKGROUND & AIMS: Although bacterial bowel flora may be one of the contributing factors in the pathogenesis of chronic mucosal inflammation, antibiotic treatment has no established role in ulcerative colitis. The aim of the study was to evaluate the role of ciprofloxacin in the induction and maintenance of remission in ulcerative colitis in patients responding poorly to conventional therapy with steroids and mesalamine. METHODS: Ciprofloxacin (n = 38; 500-750 mg twice a day) or placebo (n = 45) was administered for 6 months in a double-blind, randomized study with a high but decreasing dose of prednisone and maintenance treatment with mesalamine including follow-up for the next 6 months. Clinical assessment and colonoscopic evaluation were performed at 0, 3, 6, and 12 months. Treatment failure, the primary end point, was defined as both symptomatic and endoscopic failure to respond. RESULTS: During the first 6 months, the treatment-failure rate was 21% in the ciprofloxacin-treated group and 44% in the placebo group (P = 0.02). Endoscopic and histological findings were used as secondary end points and showed better results in the ciprofloxacin group at 3 months but not at 6 months. CONCLUSIONS: Addition of a 6-month ciprofloxacin treatment for ulcerative colitis improved the results of conventional therapy with mesalamine and prednisone.     

Management of ingested foreign bodies within the appendix: a case report with review of the literature

A case is reported of an elective appendectomy in a patient with known ingestion of a sharp foreign body. The metal drill bit was ingested unintentionally 3 months before presentation at our institution. Plain abdominal films demonstrated the foreign body in the right lower abdominal quadrant. Because the gold dental drill bit was sharp and thought to be lodged in the terminal ileum or cecum, an attempt was made to remove the object during colonoscopy. This attempt was unsuccessful because no drill bit could be detected in the colon or terminal ileum. A laparoscopic exploration was performed, and the foreign body was found to lie in the appendix, after bowel manipulation under fluoroscopic guidance and with direct laparoscopic visualization. A laparoscopic assisted appendectomy was performed. On pathologic examination the drill bit was embedded in the tip of the appendix with signs of intramucosal acute inflammation. Management and indication for surgery of foreign bodies in the appendix are discussed, and we review the related literature. This is the second reported case of a dental drill bit in the appendix causing appendicitis.     

Visual agnosia with bilateral temporo-occipital brain lesions in a child with autistic disorder: a case study

A 2-year-old boy meeting the criteria for autistic disorder was diagnosed 2 years later with a visual agnosia characterised by a combination of certain aspects of associative and apperceptive agnosia. MRI then revealed a severe encephalomalacia of the right temporal lobe and bilateral temporo-occipital areas. This association is discussed in terms of a clinical and aetiological relation between autistic disorder and visual agnosia.     

Fourth molars: a clinical study

Supernumerary teeth may be found in both the primary and permanent dentition, although they are more common in the permanent dentition. Presence of a fourth molar is rare, and such a tooth is almost invariably impacted. Dental practitioners should be aware of the possibility of encountering this rare supernumerary, its diagnosis and treatment. The authors of this article conducted a survey of patients in Montreal, looking specifically at the prevalence, aetiology, diagnosis, pathology and treatment of fourth molars. Their findings are reported here, and compared with data from the literature over the past 15 years.
