Organophosphate intoxication as a consequence of mouth-to-mouth breathing from an affected case.

We report three cases of organophosphate (OP) poisoning. One patient was a 19-year-old woman who drank OP compounds in an attempt at suicide. The other two patients became intoxicated on the way to the hospital during mouth-to-mouth breathing. The first patient died in the emergency department, and the other two were taken to the ICU. There, they were treated with atropine and pralidoxime. Three days later, all symptoms and signs had disappeared, and they were discharged from the hospital satisfactorily.

Custom finger guard-mouth prop as an alternative to conventional mouth props.

Conventional mouth props are an essential part of a dentist's armamentarium and are irreplaceable in certain dental situations. These props, however, may provide too harsh an approach or be injurious in other situations. The custom-made finger prop is a valuable alternative to the other mouth props when treating the young or handicapped.

Emergency ventilation--an alternative to mouth-to-mouth resuscitation.

The risk of infection being transmitted during mouth-to-mouth resuscitation is low, but health care professionals cite this as a reason for avoiding the procedure. Anthony Kemp discusses this issue and describes how the use of a pocket mask is a more acceptable alternative.

[The zinc concentration in the dental plaque after zinc chloride mouth rinsing in relation to previous mouth rinsings with different pH values].

The zinc content in dental plaque after mouth rinsing with 0.2% zinc chloride solution is dependent on previous mouth rinsing with different pH value. Zinc retention is strongly reduced by rinsing with citric acid solution (pH value 1.0). Zinc retention is growing with increasing pH value when rinsing was made with sodium citrate buffer solution with increasing pH value. A rinsing with sodium citrate buffer solution (pH value 6.3) following a 0.2% zinc chloride solution leads to a drastic reduction of the zinc content. However, a chlorhexidine solution with the same pH value leaves no washing out effect.

On mouth-to-mouth.

Health care providers are becoming increasingly reluctant to perform mouth-to-mouth resuscitation. While it may be prudent to exercise caution in this endeavor, it is important to appreciate the potential consequences of delaying this lifesaving procedure.

Reluctance of internists and medical nurses to perform mouth-to-mouth resuscitation.

BACKGROUND: Physicians and nurses constitute a major part of citizen cardiopulmonary resuscitation responders and serve as educators and resource personnel concerning cardiopulmonary resuscitation. We decided to determine if fear of infectious disease has dampened physician and nurse response to perform mouth-to-mouth resuscitation (MMR). METHODS: Four hundred thirty-three internists and one hundred fifty-two medical nurses responded to presentations of mock cardiac arrest scenarios. RESULTS: Forty-five percent of the physicians and 80% of the nurses would refuse to do MMR on a stranger. Between 18% and 25% of nurses and attending internists would not do MMR on a child. Being born in the United States or white racial background decreased the reluctance of the respondents to perform MMR. Only 15% of the respondents would do MMR on a stranger in a gay neighborhood. All respondents that would not do MMR stated that their reason involved fear of contracting communicable diseases, especially acquired immunodeficiency syndrome. CONCLUSIONS: Internists and medical nurses are highly reluctant to perform MMR. We recommend that the teaching of MMR should emphasize performance on children and family members where willingness to perform MMR is high. We urge public education along with widespread availability of effective barrier masks to resuscitate MMR itself.

Differences between sniff mouth pressures and static maximal inspiratory mouth pressures.

Measurements of static maximal inspiratory mouth pressure (PImax) and dynamic sniff mouth pressure (Psniff) are frequently used to assess inspiratory muscle strength. The aim of the present study was to examine, in 42 healthy subjects, the equivalence of PImax and Psniff, the influence of body posture on PImax and Psniff, and the effects of nasal patency and repeated manoeuvres on Psniff. PImax was significantly higher than Psniff, 11.05 +/- 0.42 versus 8.53 +/- 0.31 kPa. Because of the low agreement between PImax and Psniff, the two measurement methods were not interchangeable. The limits of agreement were 2.56 +/- 3.92 kPa. Sitting PImax was 11.05 +/- 0.42 kPa, and supine PImax was 9.36 +/- 0.41 kPa. Sitting and supine Psniff were 8.53 +/- 0.31 kPa and 7.52 +/- 0.33 kPa, respectively. Psniff performed with one nostril open instead of two, was higher: 9.67 +/- 0.32 kPa left and 9.62 +/- 0.32 kPa right versus 8.53 +/- 0.31 kPa when both nostrils were open. After 20-28 sniff manoeuvres, Psniff fell from 8.43 +/- 0.31 kPa to 7.83 +/- 0.30 kPa, suggesting some mechanism of inspiratory muscle fatigue. We conclude that measurement of sitting PImax yields the highest values for inspiratory muscle strength. The two measurement methods, Psniff and PImax, are not interchangeable. Measurement of Psniff is affected by nasal patency.

Immediate protection of swine from foot-and-mouth disease: a combination of adenoviruses expressing interferon alpha and a foot-and-mouth disease virus subunit vaccine.

We have previously shown that swine inoculated with recombinant, replication-defective human adenovirus type 5 containing the porcine interferon alpha gene (Ad5-pIFNalpha) are completely protected when challenged 1 day later with virulent foot-and-mouth disease virus (FMDV). In the current study, we examined the duration of protection afforded swine by Ad5-pIFNalpha and the ability of a combination of Ad5-pIFNalpha and a FMDV subunit vaccine delivered by Ad5-A24 (an Ad5 vector containing the capsid coding region of FMDV serotype A24 Cruzeiro and the 3C proteinase coding region of FMDV serotype A12) to induce immediate as well as long-lasting protection against homologous FMDV challenge. Groups of swine were inoculated with Ad5-pIFNalpha and challenged with virulent FMDV A24 1, 3, 5, and 7 days postinoculation (dpi) or 1 day preinoculation. All animals challenged 1 and 3dpi were completely protected from disease. The animals in the remaining groups had either no clinical signs of disease or clinical signs were delayed and less severe compared to the control group. Swine inoculated with a combination of Ad5-pIFNalpha and Ad5-A24 and challenged 5dpi were all completely protected from disease and developed a significant FMDV-specific neutralizing antibody response.

Detection of foot-and-mouth virus antibodies using a purified protein from the high-level expression of codon-optimized, foot-and-mouth disease virus complex epitopes in Escherichia coli.

A codon optimized DNA sequence coding for foot-and-mouth disease virus (FMDV) capsid protein complex epitopes of VP1 amino acid residues 21-40, 135-160, and 200-213 was genetically fused to the C-terminal end of a glutathione-S-transferase (GST) gene in pGEX-6P-1 vector with the synonymous codons preferred by Escherichia coli . The gene was synthesized using PCR and subsequently expressed in E. coli producing an intracellular, soluble fusion protein that retained antigenicity associated with FMDV antibodies by western blot analysis. The chimera was purified from bacterial lysates by affinity chromatography and could be used in ELISA tests for antibodies against FMDV.

[Results of primary and combined radiotherapy of mouth carcinomas (tongue, tonsil, maxilla, mandible, palate, floor of the mouth cheek mucosa)].

Responses to highvoltage radiotherapy of 320 patients with carcinomas of the oral cavity are discussed. Five year survival rate according to the stage of the, disease were the following ones: in carcinoma of the anterior 2/3 of the tongue and floor of the mouth 20-60%, buccal mucosa, upper and lower jaw 30-50%, base of the tongue 26% and tonsil 30-100%. After simultaneous irradiation of the efferent lymphatics in parimary N0 patients, whose primary tumor subsequently was under control, a significantly lower frequency of metastases to the lymph nodes was found than without coirradiation of the lymph flow. Clinically verifiable metastases of the lymph nodes are also controllable to a high percentage by radiotherapy alone: Only in a little more than five per cent of the primary N1-3 patients with the parimary tumor being under control, additional metastases of the lymph nodes developed later on. The complication rate was 6.8 per cent. Most frequently, osteonecrosis was involved, indeed occurring chiefly in cases, where a primary skeletal manifestation of the tumor already was existing.

[Eosinophilic ulcer of the mouth mucosa. Differential mouth ulcer diagnosis].

Eosinophilic ulcers of the oral mucosa represent a rare, self-limiting disease of unknown origin. Single lesions occur typically in the oral cavity or on the lower lip. Characteristically, they have a short history and resolve spontaneously. Diagnosis is verified by the histologic feature of a deep polymorphic inflammatory infiltrate with numerous eosinophils. The clinical aspect shows a usually nontender ulcer with a white or yellowish base and elevated indurated borders or a tumor with central ulceration. Lymphadenopathy is not found. Differential diagnoses include malignant tumors and the primary stage of syphilis. We present three cases recently diagnosed in our department to show the characteristics and the different appearances of the disease. A 74-year-old woman presented with an ulcer at the base of the tongue, a 59-year-old man had one on the lower lip, and in a 48-year-old man the lesion was atypically located at the edge of the mouth. Here we demonstrate the importance of knowledge of the disease, its course, and the characteristic histology to avoid troublesome diagnostic and therapeutic procedures.

Re-assessing the likelihood of airborne spread of foot-and-mouth disease at the start of the 1967-1968 UK foot-and-mouth disease epidemic.

The likelihood of airborne spread of foot-and-mouth disease at the start of the 1967-1968 epidemic is re-assessed in the light of current understanding of airborne disease spread. The findings strongly confirm those made at the time that airborne virus was the most likely cause of the rapid early development of the disease out to 60 km from the source. This conclusion is reached following a detailed epidemiological, meteorological and modelling study using original records and current modelling techniques. The role played by 'lee waves' as the mechanism for the spread is investigated. It is thought that they played little part in influencing the development of the epidemic. A number of lessons learned from the work are drawn, identifying the need for further research on the quantity and characteristics of airborne virus. The results are also used to illustrate what advice would have been available to disease controllers if the outbreak had occurred in 2004.

Evidence of partial protection against foot-and-mouth disease in cattle immunized with a recombinant adenovirus vector expressing the precursor polypeptide (P1) of foot-and-mouth disease virus capsid proteins.

A recombinant live vector vaccine was produced by insertion of cDNA encoding the structural proteins (P1) of foot-and-mouth disease virus (FMDV) into a replication-competent human adenovirus type 5 vaccine strain (Ad5 wt). Groups of cattle (n = 3) were immunized twice, by the subcutaneous and/or intranasal routes, with either the Ad5 wt vaccine or with the recombinant FMDV Ad5-P1 vaccine. All animals were challenged by intranasal instillation of FMDV 4 weeks after the second immunizations. In the absence of a detectable antibody response to FMDV, significant protection against viral challenge was seen in all of the animals immunized twice by the subcutaneous route with the recombinant vaccine. The observed partial protection against clinical disease was not associated with a reduction in titre of persistent FMDV infections in the oropharynx of challenged cattle.

[Antigenic structure of the foot-and-mouth virus. V. Protection of naturally susceptible animals from foot-and-mouth disease using a synthetic peptide].

We have synthesized the peptide representing 135-159 VP1 sequence of A22 strain of the foot-and-mouth disease virus (FMDV). The synthetic peptide induced 100% protection of guinea pigs against the disease. Two-fold immunization of cuttle with the peptide and single immunization of sheep induced full protection of the animals against A22 strain of FMDV.

[Impression taking in the edentulous mouth with special regard to closed mouth impression with simultaneous determination of the jaw relation].

In view of the increase in mean life expectancy and in the need for care in the gerostomatological sphere, more attention must be paid to such methods which optimize the construction of full dentures from the anatomico-pathological viewpoint, exert a rationalizing effect, and are likely to improve the success rate in the treatment of edentulous patients. The method of closed mouth impression and simultaneous determination of the jaw relation refers to well-proved principles of impression making, considers new findings concerning the determination of the jaw relation, incorporates modern materials and instruments, and forms the system character of clinico-technological measures.

Detection of foot-and-mouth disease by reverse transcription polymerase chain reaction and virus isolation in contact sheep without clinical signs of foot-and-mouth disease.

Two non-vaccinated sheep were experimentally infected with FMDV and one day later 4 other sheep were brought in contact. Although the contact sheep showed no clinical signs, serology indicated that all sheep became infected. Various secretion samples, taken over a period of at least one month, and various tissue samples were examined for the presence of FMDV by RT-PCR and by virus isolation. FMDV was most often found in saliva (mouth swabs), followed by nasal secretion and sera. Faecal material, wool and milk were less suitable. The period of detection with the highest frequency of positive isolations was between 2 to 4 days pi for the infected sheep and between 5 to 10 days pc for the contact animals. It was established that in subclinically infected sheep, with a very low amount of virus present, FMD viral RNA could be detected by a sensitive RT-PCR-ELISA although virus isolation and standard RT-PCR remained negative. Moreover there was some evidence of active spreading of FMDV from the contact sheep to two sentinel pigs. This indicates that serologically positive contact sheep without clinical signs may be considered as a danger for the transmission of FMDV.
