[Virus diseases of the mouth mucosa].

In accordance with the system of viral species, viral disorders of the oral mucosa may be classified with regard to their intensity of affection. There are but few viral infections exclusively affecting the oral mucosa like e.g. 1. Glossitis papulosa of Michelson, representing a special form of vaccinia inoculata, 2. Gingivo-stomatitis herpetica and 3. warts of the mucosa or condyloma-like papillomas of the oral mucosa including oral papillomatosis, that, itself shows morphological and clinical similarities to laryngeal papilloma. A second group of disorders mainly affecting the oral mucosa includes the "Aphthoid of Pospischill and Feyrter", Zahorsky's herpangina and other viral infections by the Coxsackie group, like vesicular stomatitis. The 3rd group represents viral infections of other organs in which affection of the oral mucosa is a prerogative, e.g. smallpox, varicella, foot-and-mouth disease and pharyngo-conjunctival fever. A 4th group includes those viral infections of the organs in which co-affection of oral mucosa occurs frequently or once in a while (at occasions). Here, we find eczema vaccinatum, herpes zoster, herpes simplex of the oral mucosa mostly on the hard palate, eczema herpeticatum, post-herpetic Erythema exsudativum multiforme, Mononucleosis infectiosa Pfeiffer, viral flu, German measles, parotitis epidemica, rubeola and ECHO-exanthema. A 5th and last group is made up by viral infections of other organs, in which affection of the oral mucosa hardly occurs at all. This group contains paravaccinal Ecthyma contagiosum, poliomyelitis, viral infection of the city of Marburg and some Arbovirus infections. Relatively few viral disorders never co-exist with lesions on the oral mucosa like e.g. Virus-hepatitis or some viral encephalitides. Groups 1 and 2, most important of all, are presented in detail regarding clinics, diagnostics, differential-diagnosis and therapy. The disorders within the other 3 groups are discussed only regarding their importance in the field of ENT-related symptoms of the oral mucosa. A number of pictures and tables completes important clinical details and give further hints to their differential-diagnosis.

Postoperative recurrence in patients with intestinal Behçet's disease.

PURPOSE: The postoperative course of intestinal Behçet's disease was studied in nine patients who had undergone a total of 15 operations due to intestinal ulcers. METHODS: These patients were followed up for an average of 6.0 years (range, 1 year, 3 months to 13 years, 10 months) after each operation and they were repeatedly examined by double-contrast radiography and/or colonofiberscopy. RESULTS: Recurrence of intestinal ulcers was observed in 12 (80 percent) of the 15 surgical cases. The incidence (50 percent) of postoperative recurrence in six cases in which intraoperative endoscopy revealed no abnormality in the retained intestine was lower than that (100 percent) in nine cases without this examination. Recurrent intestinal lesions in most cases were demonstrated as multiple aphthoid ulcers in the ileum near the ileocolectomy, or as one or two deep ulcers at the ileocolectomy site. The recurrent ulcers were successfully treated by various medical therapies, but the effectiveness of these therapies was only temporary. CONCLUSION: In the case of this disease, intraoperative endoscopy may be useful for preventing postoperative recurrence and periodic follow-up examination with radiography and endoscopy should be performed, even after surgery.

Expression of HLA-DR antigens on colonic epithelium around lymph follicles. An anomalous expression in Crohn's disease.

The relationship between the lymph follicle and expression of HLA-DR antigens on the colonic epithelium was investigated. Colonic specimens containing lymph follicles were examined immunohistochemically for HLA-DR expression. Thirty-six biopsy specimens (29 from macroscopically uninvolved areas and seven from aphthoid lesions) were obtained from 10 patients with Crohn's disease, and another 43 specimens were obtained from 33 patients with various intestinal diseases (non-Crohn's disease). HLA-DR antigens were expressed on the epithelium around the lymph follicle in both groups. However, the rate of expression (31/36) in Crohn's disease was significantly higher than that (5/43) in non-Crohn's diseases (P < 0.001). In addition, the extent and intensity of expression were broader and stronger in Crohn's disease than in non-Crohn's disease. This study is the first demonstration of anomalous HLA-DR expression on the epithelium around the lymph follicle in Crohn's disease.

Assessment of blood flow in the small intestine by laser Doppler flowmetry: comparison of healthy small intestine and small intestine in Crohn's disease.

Blood flow and blood distribution were investigated in 40 patients with normal small intestine and the relation between blood flow and the morphological features of Crohn's disease was examined in 11 patients with Crohn's disease by laser Doppler flowmetry from the serosal side during surgery. In normal small intestine, blood flow was measured at six points: upper, middle, and lower small intestine, each of the mesenteric borders, and the antimesenteric surface. In Crohn's disease, macroscopically normal tissue and affected lesions were observed in detail by intraoperative endoscopy after blood flow measurement. The blood flow values in the normal small intestine gradually decreased from the upper to the lower small intestine. As the level of inflammation progressed in Crohn's disease the blood flow values gradually decreased; the exudative stage of Crohn's disease (aphthoid ulcer) showed blood flow values that were slightly below those in macroscopically normal tissue. These results are the first to demonstrate decreased blood flow in affected lesions in Crohn's disease and changes in blood flow according to the degree of inflammation in vivo.

Adenocarcinoma of the colon developing on the basis of Crohn's disease in childhood.

Colorectal carcinoma rarely affects children and has a dismal prognosis with 5-year survival rates as low as 2.5%-7% despite apparently radical surgery. Here we report the case of an adenocarcinoma of the sigmoid colon in a 15-year-old girl preceded by uncertain abdominal complaints of 5 years' duration. Pathological work-up revealed a tumour with lymph node metastases (pT3NI). Immunohistochemical evidence of p53 overexpression by the tumour cells raised the suspicion of an underlying Li-Fraumeni syndrome. In addition, there were aphthoid ulceration, fissuration of the non-tumorous mucosa, along with a mixed transmural infiltrate composed of macrophages, eosinophils, and non-typical giant cells, which were compatible with simultaneous Crohn's disease. Anamnestic data concerning the occurrence of idiopathic inflammatory bowel disease or colorectal carcinoma in the patient's relatives were non-contributory. The present results suggest a possible relationship between Crohn's disease and colon cancer due to the defective p53 gene product.

Rifampicin-associated pseudomembranous colitis.

We report a case of pseudomembranous colitis that developed in a patient with liver cirrhosis during anti-tuberculosis therapy with rifampicin and isoniazid. The association between rifampicin and pseudomembranous colitis has been controversial; this report, however, supports the association. Colonoscopy performed 3 days after the onset of the pseudomembranous colitis revealed only reddish patches and a few aphthoid lesions, but 4 days later pseudomembranes were apparent. The pseudomembranous colitis was successfully controlled by discontinuation of the anti-tuberculosis agents, along with the administration of lactic acid bacteria, without vancomycin or metronidazole. Possible predisposing factors for the development of pseudomembranous colitis in this patient are also discussed.

Intra-abdominal desmoplastic small round cell tumor (IDSRT).

Intra-abdominal desmoplastic small round cell tumor (IDSRT) is a rare neoplasm that develops in the abdominal cavity in young people. We experienced a 27-year-old man who visited with ascites of unknown cause. Compression of the colon was found by barium enema examination. On colonoscopic examination, diffuse white elevated lesions, about 5 mm in diameter, surrounded by rubedo, so-called aphthoid lesions, were also observed. IDSRT was diagnosed by biopsy at laparotomy, and chemotherapy with cyclophosphamide, etoposide, doxorubicin, and cisplatin was performed. The tumors shrank temporarily (partial response), but subsequently grew in size again. The patient died during the second course of chemotherapy after relapse. We present one case report, together with a review of the literature.

Clinical, biological, and endoscopic picture of attacks of Crohn's disease. Evolution on prednisolone. Groupe d'Etude Thérapeutique des Affections Inflammatoires Digestives.

One hundred forty-two patients with active colonic or ileocolonic Crohn's disease were included in a multicenter prospective study. Data collection included 28 clinical, biological, and endoscopic items; the latter were recorded according to a standardized colonoscopic protocol; a previously validated endoscopic index of severity was calculated. Oral prednisolone (1 mg/kg body wt per day) was started and maintained until clinical remission and for at least 3 and at most 7 wk. A second clinical biological and endoscopic evaluation was then performed. At initial colonoscopy, mucosal lesions were, by decreasing order of frequency, superficial ulcerations, deep ulcerations, mucosal edema, erythema, pseudopolyps, aphthoid ulcers, ulcerated stenosis, and nonulcerated stenosis (93%, 74%, 48%, 44%, 41%, 35%, 10%, 8%, and 2% of cases, respectively). No correlation was found between the clinical activity index and any of the endoscopical data (lesion frequency and surface, endoscopic severity index). Ninety-two percent of patients underwent clinical remission within 7 wk of treatment. None of the 28 clinical biological and endoscopical items collected just before treatment could predict clinical response to steroids. Only 38 of the 131 patients in clinical remission were also in endoscopic remission. In conclusion, (a) the description and severity of colonoscopic lesions in active Crohn's disease have been quantified; (b) no correlation exists between clinical severity and nature, surface, or severity of endoscopic lesions; (c) Oral prednisolone (1 mg/kg body wt per day) induces a clinical remission in 92% of patients within 7 wk; (d) resistance to steroids cannot be predicted from the data collected before treatment onset; and (e) only 29% of patients in clinical remission also achieve endoscopic remission.

Utility of the instant (unprepared) enema in Crohn's colitis.

Thirty-seven instant (unprepared) barium enemas in 30 patients with proven Crohn's colitis were reviewed. Plain films in 28 indicated that confluence or discontinuity of the colitis did not substantially alter the pattern of faecal residue. In only one patient was residue found overlying active mucosal disease. Aphthoid ulceration was demonstrated in 27%. In five (13%) examinations the colitis was granular and indistinguishable from ulcerative colitis. In 26/37 (70%) typical stigmata of Crohn's colitis were present. There was no complication or clinical deterioration after the instant enema. The instant enema was found to be comparable to a prepared examination for the diagnosis of advanced Crohn's disease, though less accurate for demonstrating early changes.

A prospective, observational study of colonic mucosal abnormalities associated with orally administered sodium phosphate for colon cleansing before colonoscopy.

BACKGROUND: Colonic mucosal abnormalities associated with sodium phosphate colonic preparations have been described. The aim of this prospective study was to determine the frequency at which these occur and to define the endoscopic and histopathologic patterns of these changes. METHODS: Within a 16-month period, 730 of patients referred for elective colonoscopy entered the study. Patients with known inflammatory bowel disease and those taking non-steroidal anti-inflammatory drugs were excluded. A sodium phosphate solution was ingested orally 14 and 8 hours before endoscopy. After standard colonoscopy, a 3-year clinical follow-up program was conducted. RESULTS: Endoscopically, mucosal lesions, possibly associated with sodium phosphate ingestion, were visible in 24 patients (3.3%). Erosions were found in 3 patients, aphthoid lesions in 21 patients, and an ulcer in one patient. Lesions often were multiple. Histopathologically, findings included focal active inflammation in 14 of 24 patients, mucosal disruption and erosion (7/24), edema of the lamina propria (5/24), mucosal hyperemia or focal hemorrhage (5/24), lymphoid nodules (5/24), and ulceration (1/24). CONCLUSIONS: Orally administered sodium phosphate-associated colonic mucosal abnormalities are infrequent but can mimic an non-steroidal anti-inflammatory drug-induced injury or inflammatory bowel disease, and in particular must be differentiated from Crohn's disease.

Long-term follow-up for minute gastroduodenal lesions in Crohn's disease.

Endoscopic examination of the stomach and duodenum was carried out in 12 consecutive cases of Crohn's disease involving the small and large intestine. Minute lesions consistent with Crohn's disease were endoscopically discovered in the stomach in nine cases (75%) and in the duodenum in five cases (42%). The characteristic endoscopic features of these minute lesions included patchy erythema, aphthoid erosion, and a verrucous change. Epithelioid cell granulomas in the serial sectioned samples were discovered in the stomach in 10 cases and in the duodenum in four cases.

[Diagnostic imaging of inflammatory bowel disease].

This article considers the possibilities of different image acquisition techniques in the study of inflammatory bowel disease, with special emphasis on the roles of tomodensitometry and magnetic resonance imaging. Although these techniques are not superior to barium follow through studies or conventional enteroclysis at depicting the mucosa in detail, they are very useful in the evaluation of the characteristics of the walls of the bowel loops and in the detection of possible extraluminal complications, such as abscesses, adenopathies, and mesenteric involvement. Magnetic resonance shows great potential for the study of the small bowel and is likely to play an important role in the study of inflammatory bowel disease in the near future. This recurring disease affects young patients with long life expectancies in whom exposure to ionizing radiation needs to be minimized. We explain the radiologic findings through a physiopathologic approach to the sequence of events (aphthoid ulcers, fissuring and penetrating ulcerations, formation of fistulous tracts, abscesses, mesenteric involvement) that give rise to them. We propose an objective classification based on the imaging findings that is useful for therapeutic decision making, and we describe the important role of the radiologist in the follow-up as well as in the diagnosis of this entity.

Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children.

BACKGROUND: We investigated a consecutive series of children with chronic enterocolitis and regressive developmental disorder. METHODS: 12 children (mean age 6 years [range 3-10], 11 boys) were referred to a paediatric gastroenterology unit with a history of normal development followed by loss of acquired skills, including language, together with diarrhoea and abdominal pain. Children underwent gastroenterological, neurological, and developmental assessment and review of developmental records. Ileocolonoscopy and biopsy sampling, magnetic-resonance imaging (MRI), electroencephalography (EEG), and lumbar puncture were done under sedation. Barium follow-through radiography was done where possible. Biochemical, haematological, and immunological profiles were examined. FINDINGS: Onset of behavioural symptoms was associated, by the parents, with measles, mumps, and rubella vaccination in eight of the 12 children, with measles infection in one child, and otitis media in another. All 12 children had intestinal abnormalities, ranging from lymphoid nodular hyperplasia to aphthoid ulceration. Histology showed patchy chronic inflammation in the colon in 11 children and reactive ileal lymphoid hyperplasia in seven, but no granulomas. Behavioural disorders included autism (nine), disintegrative psychosis (one), and possible postviral or vaccinal encephalitis (two). There were no focal neurological abnormalities and MRI and EEG tests were normal. Abnormal laboratory results were significantly raised urinary methylmalonic acid compared with age-matched controls (p=0.003), low haemoglobin in four children, and a low serum IgA in four children. INTERPRETATION: We identified associated gastrointestinal disease and developmental regression in a group of previously normal children, which was generally associated in time with possible environmental triggers.

Endoscopic features of chronic inflammatory bowel disease in childhood.

Flexible endoscopy, performed after oral bowel preparation and under moderate intravenous sedation, proves to be well tolerated, safe and highly effective in the diagnosis and management of children with IBD. At St Bartholomew's Hospital it is performed as the investigation of first choice, on the basis that it supplies colour documentation, histopathological and (where relevant) bacteriological evidence, which achieves certain confirmation or exclusion in almost every case and in the shortest possible time. Biopsies must always be taken, as mucosa of normal appearance can show either microscopic ulcerative colitis or Crohn's disease. When there are the characteristic 'aphthoid' ulcers, visual diagnosis of Crohn's disease is reasonably certain, particularly in early-stage disease, although amoebic and other infective causes of colitis can give misleadingly similar appearances. The endoscopist can usually inspect (and almost always biopsy) the terminal ileum, and can expect many children to show the prominent 'nodular lymphoid hyperplasia' which is essentially a normal finding-though sometimes misdiagnosed radiologically as being Crohn's deformity. However, it is important that radiological assessment by barium follow-through complements colonoscopy in view of the not infrequent cases of intestinal Crohn's disease in children where the proximal small intestine is involved, even if the colon and terminal ileum are spared.

Diversion colitis--new light through old windows.

Diversion proctocolitis is an iatrogenic disorder caused by surgical diversion of the faecal stream away from the colorectal mucosa. Such surgery may be necessary in cases of tumour, trauma or inflammatory conditions of the colorectum. Histopathological change is characterized by a chronic lymphoplasmacytic inflammatory infiltrate, and the hallmark feature, lymphoid follicular hyperplasia. Histological appearances are determined by the disease state of the colonic mucosa prior to faecal diversion. Macroscopic appearances may vary considerably, but often include aphthoid ulceration. The exact pathogenesis of the condition remains unclear, but the removal of short-chain fatty acids, present in the faecal stream, is considered an important aetiological factor. Current research areas, including the microbiology and cellular kinetics of diversion colitis, are discussed along with clinical features and treatments.

Primary gastrointestinal T-cell lymphoma resembling multiple lymphomatous polyposis.

An extremely rare case of primary gastrointestinal T-cell lymphoma involving the stomach and intestine is reported. Radiographic and endoscopic examinations showed multiple polypoid lesions covered by a normal-appearing mucosa in the stomach, duodenal bulb, and terminal ileum and numerous small aphthoid lesions throughout the entire colorectum. Histopathologic, immunohistochemical, and polymerase chain reaction studies were performed using paraffin-embedded or fresh-frozen specimens from endoscopic biopsies and endoscopic mucosal resections. All lesions were composed of small, atypical lymphoid cells, which were classified as low-grade pleomorphic lymphoma. The tumor cells expressed CD3, CD4, and the T-cell receptor gamma gene phenotype as well as human mucosal lymphocyte 1 antigen, suggesting that the lymphoma cells were derived from intraepithelial T lymphocytes. This is the first description of primary gastrointestinal T-cell lymphoma with expression of human mucosal lymphocyte 1 antigen and a novel morphology resembling multiple lymphomatous polyposis.

[Ileocecal manifestation of Schoenlein-Henoch purpura as a rare differential Crohn disease diagnosis].

In the case of a 21-year-old patient gastroscopy and coloscopy were performed because of recurrent abdominal pain with diarrhea and vomiting. Colonoscopy showed moderate signs of inflammation of the rectum and aphthoid ulcerations in the terminal ileum. Since the macroscopic and clinical presentation was compatible with Crohn's disease, therapy with sulfasalacine was started. Because histology showed only lymphoid hyperplasia and the patient was asymptomatic at that time, the medication was ceased. Recurrence of abdominal pain and weight loss, proteinuria and a recurrent palpable purpura of the shanks in synopsis with the result of the previous colonoscopy led to a suspected diagnosis of Schoenlein-Henoch purpura with cutaneous, renal and abdominal manifestation which was confirmed by dermal and renal biopsies.

Prediction of the clinical course of Behçet's colitis according to macroscopic classification by colonoscopy.

BACKGROUND AND STUDY AIMS: The lesions in Behçet's colitis show aphthoid or punched-out ulceration, but the macroscopic types of lesion found have not been defined. To predict the clinical outcome in patients with Behçet's colitis according to the colonoscopic findings, we classified the characteristic colonic ulcers, evaluated the efficacy of medical treatment on colonoscopic lesions, and calculated the operation rates and recurrence rates relative to the macroscopic types. PATIENTS AND METHODS: The medical records and colonoscopic photographs of 50 patients with Behçet's colitis were reviewed. The colonic lesions were examined by colonoscopy in patients with Behçet's disease and gastrointestinal symptoms. The colonoscopic findings were categorized into three types of ulceration: volcano-like, geographic, and aphthous. The efficacy of medical treatment was assessed by follow-up colonoscopy or double-contrast barium enema four to eight weeks after treatment, and recurrence of the lesions was evaluated during the follow-up periods. Cumulative surgery rates were obtained using the Kaplan-Meier method. RESULTS: The macroscopic classification of colonic ulcers identified 25 of 50 patients (50%) with volcano-type lesions, 11 (22%) with the geographic type, and 14 (28%) with the aphthous type. The rates of complete remission after medical treatment and surgery, respectively, were six of 25 (24%) and 13 of 25 (52%) with volcano-type ulcerations; eight of 11 (73%) and one of 11 (9%) with the geographic type; and nine of 14 (64%) and two of 14 (14%) with the aphthous type. The endoscopic and clinical recurrence rates were nine of 19 (47%) in volcano-type ulcerations, one of nine (11%) in the geographic type, and one of 11 (9%) in the aphthous type. CONCLUSION: Volcano-type ulcerations in Behçet's colitis showed a less favorable response to medical treatment, a more frequent requirement for surgery, and more frequent recurrences than the geographic and aphthous types of ulcerations.
