Abstract
Various oral and dental problems have been attributed to orotracheal intubation in the neonatal period. A case is described of a child whose dental anomalies are ascribed to multiple orotracheal intubations for the management of a complex cardiac abnormality. Six intubations were required between the ages of 9 days and 4 years for investigation and surgery. His maxillary right primary central incisor did not erupt until 3 years of age and the maxillary left was still unerupted at 6 years and 10 months and was rotated in its crypt. At this time, the mandibular primary incisors were physiologically mobile but the maxillary right primary central incisor remained firm. Both maxillary primary central incisors were extracted and examined histologically and showed abnormal morphology, enamel hypoplasia, and disordered dentine formation and root resorption. Subsequent eruption of the left permanent central incisor revealed hypoplasia of its incisal edge. It is suggested that the delayed eruption and abnormal morphology of the primary incisors were due to pressure effects on the overlying mucosa, follicular displacement and localized trauma caused by intubation. This case highlights the importance of monitoring the developing dentition of patients with a history of orotracheal intubation, so that interceptive treatment may be instituted when appropriate.

Abstract
Congenital dislocation of the hip (CDH) affects two children per 1000, with potentially serious consequences. Student health visitors in Northern Ireland learn screening techniques for CDH at a half-day workshop at a regional hospital. In order to evaluate the adequacy of this preparation, 71 qualified health visitors were surveyed to assess their knowledge relating to CDH, their views on the adequacy of the training, and their opinions about referral of positive cases. Knowledge in some areas was poor and preparation was considered too short. Direct referrals of positive cases to orthopaedic clinics, without a general practitioner acting as an intermediary, was a frequently cited desire. Recommendations include extending the training for those involved in CDH screening while ensuring that experienced health visitors, from whom novices learn, are themselves using correct procedures.

Abstract
This article discusses how NDUs fit into the concepts that are currently governing the management of the NHS such as marketability, accountability and cost-effectiveness of care. The author argues that while there are potential difficulties, the NDU values of equality, democracy, esteem-building and personal growth are relevant in the business world of health care.

Abstract
Examination of the cranial nerves is a simple and valuable procedure following trauma to the head and neck. By understanding their courses, branches and distributions, the site of any damage may be localized. Once the site and nature of injury has been determined, correct management may be instigated. A case is presented in which there was some degree of trigeminal nerve damage following trauma. The site of damage was determined to be extracranial and therefore a conservative regimen adopted. The mechanism of injury is postulated.

Abstract
Histamine (H2)-receptor blockers are commonly used in critically ill patients to prevent gastric bleeding and have been implicated in the pathogenesis of gram-negative bacterial (GNB) nosocomial pneumonia. These experiments were undertaken to determine if cimetidine affects pulmonary GNB clearance. Groups of normal Sprague-Dawley rats were given cimetidine (75 mg/kg) or an equal volume of sterile buffer intraperitoneally every 6 hr for 24 hr prior to intratracheal challenge with 1.0 x 10(8) Pseudomonas aeruginosa. At 6 and 24 hr after challenge, animals were sacrificed and gastric pH, quantitative lung cultures, and total and differential [alveolar macrophages (AM) and polymorphonuclear leukocytes (PMN)] cell counts in bronchoalveolar lavage fluid were performed. Results showed that cimetidine therapy resulting in gastric pH greater than 4.0 has no effect on the pulmonary clearance of P. aeruginosa.

Abstract
A case is described of gingival fibromatosis in a 10-year-old boy, in which gingival tissue was removed using a CO2 laser. The advantages of this method over conventional surgery were minimal bleeding and pain, allowing treatment of all quadrants in one visit. The disadvantages were the potential risks to the teeth and to the endotracheal tube. In this case laser treatment achieved a good result with minimal post-operative discomfort, which is an important consideration for children.

Abstract
Public understanding of cardiovascular disease (CVD) risk factors and primary prevention has increased, due in part to community prevention efforts. However, many segments of society are difficult to reach. Such groups still need public education to acquire the knowledge that can lead to behavior change. Community intervention programs in rural areas face the challenge of disseminating health information to widely scattered populations isolated by difficult terrain and weather, and restricted by the sparsity of channels for mass communication. School health promotion programs, because of the special role schools play in rural communities, can help reach rural populations. During a five-year period, the Otsego-Schoharie Healthy Heart Program, a state-funded community intervention program, provided presentations to 18% of the combined total population of two rural counties through its school-based component. It also helped promote other program initiatives by establishing linkages in the community. Schools provide an effective channel for health promotion efforts to reach rural populations.

Abstract
This study investigated the occupational exposure to carbon monoxide (CO) of a group of blast furnace workers from an integrated steelworks, compared to a control group having no significant occupational CO exposure from other areas in the same works. The study was undertaken in 1984 at Port Kembla, New South Wales. Carboxyhaemoglobin (COHb) levels before and after an eight-hour work shift were measured in 98 male steelworkers: 52 from two CO-exposed iron blast furnaces and 46 controls from production areas in the same steelworks. The sample was stratified by smoking habits. Environmental air CO levels had been found to be consistently higher on one furnace than on the other. Absorption of CO from the working environment occurred in workers on the blast furnace with higher CO levels, regardless of smoking habits. On this blast furnace, some readings of COHb levels after a workshift in nonsmokers approached the proposed Australian occupational limit of 5 per cent COHb saturation. Overall, workers with the highest occupational exposure who smoked most heavily had the highest absorption of CO over a work shift. Biological monitoring gives an accurate measure of individual worker 'dose' of CO from all sources. Both environmental monitoring and biological monitoring need to be included as part of a program for controlling occupational CO exposure.

Abstract
In rodent malaria model systems, protective immunity induced by immunization with irradiated sporozoites is eliminated by in vivo depletion of CD8+ T cells, and adoptive transfer of CTL clones against the circumsporozoite protein protects against malaria. We recently demonstrated that volunteers immunized with irradiated Plasmodium falciparum sporozoites produce CTL against peptide 368-390 of the P. falciparum circumsporozoite protein. To determine whether natural exposure to malaria induced similar CTL, we studied 11 adult, male, life-long residents of a highly malarious area of Kenya, who were selected because their lymphocytes had been shown to proliferate after stimulation with peptides 361-380, 371-390, or 368-390 and because nine had been resistant to malaria in previous studies. In four of the 11 individuals there was peptide-specific, genetically restricted, CTL activity. In all four individuals, this activity was unaffected by depletion of CD4+ T cells. In three volunteers the activity was eliminated or reduced by depletion of CD8+ T cells; in the fourth volunteer the CD8+ T cell depletion was uninterpretable. This first demonstration of CD8+ T cell, genetically restricted, Ag-specific CTL against a malaria protein among individuals exposed to endemic malaria provides a foundation for studying the relationship between circulating CTL and resistance to malaria infection.

Abstract
Non-attendance at out-patient clinics is a persistent, worldwide problem. In contrast with previous research, a qualitative approach was used in this study to examine reasons for non-attendance at out-patient clinics in one Belfast hospital, by exploring perspectives of general practitioners (GPs), hospital staff and defaulters. Findings revealed conflicts of opinion between GPs and hospital staff on appropriate management of certain medical and postnatal patients. Patients' reasons for defaulting were wide-ranging; however, 32% of those interviewed did not attend, or were recorded as non-attenders, for reasons relating to inefficient hospital administration. It is concluded that the causes of non-attendance were multifactorial, and non-attenders could not be stereotyped as irresponsible. Suggested measures to alleviate the problem include discussion between groups of professionals on responsibility for care of medical and postnatal patients, increased negotiation between patients and physicians in order to develop agreed programmes of care, and, where possible, a shifting of the onus of responsibility for making and cancelling appointments onto patients.

Abstract
'Research' has become a fashionable word in nursing circles, but doubts remain about whether nursing is justified in calling itself a research-based profession. The author examines the rhetoric surrounding the word, before citing examples of how research is affecting nursing practice. More work is needed to ensure the gap is closed between talking about research and using it, but nurses should not lose sight of the ultimate aim of research--to enhance the primary vocation of caring.

Abstract
A series of [1,2,4]triazolo[4,3-alpha][1,4]benzodiazepines bearing an ethynyl functionality at the 8-position and the isosteric thieno[3,2-f][1,2,4]triazolo[4,3-alpha][1,4]diazepines were prepared and evaluated as antagonists of platelet activating factor. The effects of substitution were explored in in vitro and in vivo test systems designed to measured PAF-antagonistic activity. Results are discussed and compared with previously published data. Many of the compounds had activity superior to WEB 2086, compound 1. In general, the thieno analogues exhibited better oral activity than the corresponding benzodiazepines. The duration of activity upon oral administration was modulated by the substitution on the acetylenic side chain. Compounds 71 and 81 were selected for further pharmacological evaluation as a result of their good oral potency and exceptionally long duration of action.

Abstract
A 42-year-old man, seronegative for Epstein-Barr virus (EBV), received a cadaveric renal transplant. Serology from the 27-year-old male donor indicated an active EBV infection. Following treatment for acute rejection with OKT3 the recipient developed a severe systemic illness. Clinical features strongly suggested an acute EBV infection and serology showed seroconversion for EBV. The patient died and autopsy histology revealed widespread polymorphic lymphocyte infiltration in lymph nodes and solid organs. To our knowledge this is the first report of a kidney being transplanted from a donor who was subsequently shown to have had EBV infection at the time of organ retrieval. The EBV status of an organ donor should be considered more frequently.

Abstract
The nucleotide sequence of an unusual fowlpox virus gene which maps immediately upstream from the fowlpox virus 4b gene has been determined. The 34,000 Mr protein predicted to be encoded by the gene contains 11 copies of a 12 amino acid serine-rich repeat sequence. The seven amino-terminal copies of the repeat sequence are perfectly conserved but variation exists in the four carboxy-terminal copies. Three peptides were synthesized which contained either one copy of the repeat sequence, two copies of the repeat sequence or a hydrophilic amino-terminal region of the protein. All three peptides when injected with adjuvant into rabbits gave rise to antibodies which reacted strongly on Western blots of purified fowlpox virus proteins with a 39,000 Mr protein. When directly compared in Western blots the antipeptide sera were shown to recognize a protein comigrating with one of the two immunodominant proteins recognized by chicken anti-fowlpox virus sera taken 2 weeks post-infection. The virion protein is removed by treatment with sodium deoxycholate suggesting that it is located at or near the surface of the virus.

Abstract
The DNA sequence of the fowlpox virus genome corresponding to the vaccinia virus D6 to A1 region has been determined. Translation of this sequence reveals fowlpoxvirus gene homologues corresponding to the D6, D7, D9, D10, D11, D12, D13 and A1 genes of vaccinia virus. In contrast, no gene homologue for the non-essential vaccinia virus D8 gene was present in fowlpox virus. Instead, a gene transcribed from the opposite strand to the vaccinia virus D8 gene showing no homology to any previously sequenced poxvirus gene was present. The amino terminus of the fowlpox virus D9 homologue had undergone substantial changes, including frameshifts which would be predicted to inactivate the gene. Insertion of a gene cartridge composed of the vaccinia virus p7.5 promoter and the lacZ gene into the fowlpox virus D8, D9 and D10 genes in vitro, followed by recombination into fowlpox virus, was carried out. Stable insertion mutants with the correct genotype were obtained for D8 and D9 which, when tested in chickens did not appear to have been attenuated. No stable insertion mutants were obtained for D10, indicating that this gene probably encodes a function which is essential for virus replication. The D8 and D9 genes of fowlpox virus represent useful insertion sites for the construction of recombinant fowlpox virus vaccines.

Abstract
Eighty-seven consecutive children and young adults with acute nonlymphocytic leukemia (ANLL) were treated uniformly with induction chemotherapy based on daunorubicin and cytarabine (ara-C), with the addition of etoposide (VP-16) and azacytidine (5-Az) for refractory patients. Of the 65 patients who entered complete remission, 42 were eligible for assessment of response to intensive chemotherapy consisting of four pairs of drugs administered in sequential fashion. Nineteen others with available histocompatibility locus antigen (HLA)-compatible donors were assigned to receive allogeneic bone marrow transplants within 16 weeks from their dates of complete remission. Durations of continuous complete remission (CCR) in the two groups were not significantly different at a median follow-up time of 6 years (P = .30 by log-rank analysis). Kaplan-Meier estimates of CCR probabilities (+/- SE) at 6 years were 43% +/- 13% (transplantation) and 31% +/- 7% (sequential chemotherapy). Postremission failures in the sequential chemotherapy group resulted from bone marrow relapse in 23 of 29 patients (79%), whereas in the transplantation group, failures were equally divided between marrow relapse and transplantation-related complications of graft-versus-host disease (GVHD) or infection due to the immunosuppressive effects of ablative chemotherapy. Comparison of hematologic remission curves indicated a significant advantage for marrow transplantation in terms of systemic leukemia control (P = .06). Thus, in programs of intensive chemotherapy of the type described here, allogeneic marrow transplantation should be seriously considered as alternative therapy for patients in first remission who have an HLA-matched sibling donor, provided that effective methods for control of transplant-related complications are available.
