vaccines and recommendations for their use in inflammatory bowel disease.the patient with inflammatory bowel disease will be predisposed to numerous infections due their immune status. it is therefore important to understand the immune and serologic status at diagnosis and to put the patient into an adapted vaccination program. this program would be applied differently according to two patient groups: the immunocompromised and the non-immunocompromised. in general, the first group would avoid the use of live-virus vaccines, and in all cases, inflammatory bowel diseas ...023538680
feasibility of cross-protective vaccination against flaviviruses of the japanese encephalitis serocomplex.serological cross-reactivity providing cross-protective immunity between antigenically related viruses is a cornerstone of vaccination. it was the immunological basis for the first human vaccine against smallpox introduced more than 200 years ago, and continues to underpin modern vaccine development as has recently been shown for human papillomavirus vaccines, which confer cross-protection against other oncogenic papillomavirus types not present in the vaccine. here, we review the feasibility of ...022309667
vaccinating patients with inflammatory bowel disease.patients with inflammatory bowel disease (ibd) are not vaccinated at the same rate as general medical patients. ibd places patients at increased risk for developing vaccine-preventable illnesses, and this risk is further exacerbated by immunosuppressive therapy. therefore, gastroenterologists should familiarize themselves with health maintenance measures pertaining to patients with ibd. this article highlights the vaccinations required for patients with ibd, especially those who are immunosuppre ...027917091

molecular cloning of viral dna from human genital warts.the dna of human papilloma virus type 6 (hpv 6) has been cloned in escherichia coli k-12 by using pbr322 as vector. the dna was cloned at the bamhi and ecori cleavage sites. this dna was mapped by employing further restriction endonucleases and by terminal labeling. no major differences were noted as compared to hpv 6 dna originating directly from a genital wart. the existence of at least two dna subtypes (hpv 6a and 6b) became apparent.19816275126
[condylomata acuminata].condylomata acuminata are benign epitheliomas which are caused by the human papilloma virus. 8 subgroups (variants) of the virus are known up to now. condylomata acuminata are infectious, the virus being transferred by direct contact with a lesion. condylomata acuminata are found more often in males than in females and never occur in children prior to the age of two years. the peak incidence is between 19 and 22 years of age. greatly proliferating condylomata acuminata (type buschke-löwenstein) ...19816281993
human papillomavirus (hpv) in condylomatous lesions of cervix.ninety-seven cervical condylomata classified histologically as flat condyloma (planum), papillary condyloma (acuminatum), and endophytic condyloma were studied by transmission electron microscopy (tem) and by immunoperoxidase technique (ipt) for the presence of human papillomavirus (hpv) particles and antigen, respectively. both techniques localized hpv chiefly in nuclei of koilocytotic cells. hpv particles were found in 25% of the cases by tem and hpv antigen was detected in 48% of the cases by ...19816278970
identification of papillomaviruses in butchers' warts.we have studied the papillomaviruses found in the hand warts of 60 butchers, most of them from 2 distant slaughterhouses. warts differing in morphology and location were studied separately. the viruses were identified by molecular hybridization, restriction enzyme analysis and immunofluorescence. four known human papillomaviruses (hpv-1, hpv-2, hpv-3, hpv-4) were detected and one hitherto unknown papillomavirus was identified in 9 butchers. the dna of the latter virus did not anneal with any of ...19816257792
human papillomavirus infection of the cervix: the atypical condyloma.we report on 162 cases of human papillomavirus (hpv) infection of the cervix seen in a two-year period in which the cell sample showed such marked atypia that errors of interpretation could easily have been made. these atypical condylomata are difficult to diagnose cytologically as well as histologically because they mimic dysplasia or carcinoma in situ and, on smears, even invasive squamous carcinoma. hpv particles associated with fibrillar material were found within nuclei of these lesions; th ...19816258367
presence of human papilloma viral antigens in juvenile multiple laryngeal papilloma.juvenile laryngeal papillomas, solitary laryngeal papillomas of the adult, and cylindric cell papillomas of the nose and sinuses were examined for the presence of papillomavirus antigens by means of immunocytochemistry. by using an antiserum capable of recognizing a common group antigen that reacts with papillomavirus antigens of different species, it was found that half of the juvenile laryngeal papillomas studied contained cells staining for papillomavirus antigens. no positive cells were foun ...19816258422

origin of the koilocyte in condylomata of the human cervix: ultrastructural study.twelve biopsies from condylomatous lesions of the human cervix were examined by transmission electron microscopy in order to study koilocytotic cells. the ultrastructure of koilocytes, revealed mainly cytoplasmic changes in the perinuclear area. these changes first appeared in cells of the intermediate layers and extended to the surface of the epithelium. the cells involved showed small perinuclear areas, with a fine granular material, which appeared as a lysis of the cytoplasmic matrix, forming ...19816945004
an unusual wart-like skin lesion found in a renal allograft recipient.immunosuppressed renal allograft recipients have an increased tendency to acquire warts. while studying such patients, we found a virus-induced, wart-like lesion that had an unusual histologic picture. light microscopic studies showed bizarre keratinocytes with cytoplasmic, juxtanuclear, giant, crescentic bodies and round, nuclear inclusions, by electron microscopy, the giant cytoplasmic bodies were found to be composed of tonofilaments, and the nuclear inclusions were found to be composed of pa ...19817006517
carcinoma cuniculatum (verrucous carcinoma of the skin): a clinicopathologic study of 46 cases with ultrastructural observations.forty-six examples of carcinoma cuniculatum, a rare variant of squamous cell carcinoma of the skin, were studied by means of light and electron microscopy and immunoperoxidase techniques. the tumors usually presented as ulcerated, fungating, and polypoid masses with openings of sinus tracts onto the skin surface that exuded foul-smelling greasy material when pressure was applied. on microscopic examination the tumors were seen to be composed mainly of mature squamous keratinocytes with foci of c ...19827042070
cervical intraepithelial neoplasia and 'wary' atypia: a study of colposcopic, histological and cytological characteristics.colposcopic, histological and cytological characteristics of 168 consecutive patients attending a colposcopy clinic were reviewed. a group of patients demonstrated a cluster of histological features previously related to possible human papilloma virus infection of cervical epithelium, including particularly koilocytosis, double nucleation and dyskeratosis. these patients had a significantly greater occurrence of colposcopic 'finger-like' lesion outline and colposcopic impression of warty change, ...19827093173
verruca vulgaris of the larynx: a distinctive lesion of probable viral origin confused with verrucous carcinoma.two adult males had superficial, keratotic vocal cord lesions. one was diagnosed as verrucous carcinoma, prompting a hemilaryngectomy. the other was interpreted as a squamous papilloma and was treated by local excision. both patients are disease-free 7 years and 18 months, respectively, following surgery. the histologic features of both lesions are identical to those of cutaneous verruca vulgaris, and immunoperoxidase staining for human papilloma virus was positive in one case. laryngeal verruca ...19827114361
histological changes identical to those of condylomatous lesions found in esophageal squamous cell carcinomas.esophageal specimens derived from sixty patients with an established invasive squamous cell carcinoma of the esophagus were histologically surveyed with special reference to the morphological manifestations of human papilloma virus (hpv), known to cause flat, inverted and papillomatous lesions (condylomas) in the uterine cervix. epithelial changes fulfilling the criteria of the papillomatous condyloma were present in one case, those of the inverted lesions in three cases, and those of the flat c ...19827138240
human papillomavirus 1a complete dna sequence: a novel type of genome organization among papovaviridae.the complete nucleotide sequence of human papillomavirus type 1a (7811 nucleotides) has been established. the overall organization of the viral genome is different from that of other related papovaviruses (sv40, bkv, polyoma). firstly, genetic information seems to be coded by one strand. secondly, no significant homology is found with sv40 or polyoma coding sequence for either dna or deducted protein sequences. the relatedness of human and bovine papillomaviruses is revealed by a conserved codin ...19826325156
human papillomavirus dna in cutaneous primary and metastasized squamous cell carcinomas from patients with epidermodysplasia verruciformis.dna extracted from squamous cell carcinomas from patients with the chronic wart disease syndrome, epidermodysplasia verruciformis, was analyzed for the presence of human papillomavirus (hpv)-specific dna sequences by southern blot hybridization analysis. employing an hpv probe obtained by molecular cloning of viral dna purified from benign warts from these patients, we have unequivocally identified hpv-specific nucleotide sequences in squamous cell carcinomas from these patients. restriction end ...19826280194
new human papilloma virus isolated from epidermodysplasia verruciformis lesions.human papilloma virus (hpv) was isolated from red plaques of a patient (n. f.) with epidermodysplasia verruciformis. electron microscopic examination showed characteristic particles of papilloma virus as icosahedrons about 45 nm in diameter. dna was extracted from these particles, and closed-circular dna (form i) was purified by centrifugation in cscl containing ethidium bromide. the molecular weight of the dna was about 5.0 x 10(6). a physical map of the hpv dna was constructed using several re ...19826280858
