Reproducibility and overlapping of bitewing radiographs: comparison of Eggen-bite with Kwik-bite.

In the present study the reproducibility of horizontal dimensions and of overlappings of two filmholder techniques with aiming devices (Eggen-bite and Kwik-bite) and additionally the number of overlappings on the resulting bitewing radiographs were compared. The overlapping reproducibility was significantly higher with Kwik-bite. The microdensitometric reproducibility demonstrated the same tendency, but the result was not significant. Bitewings carried out by an oral radiologist demonstrated fewer overlappings with Eggen-bite than with Kwik-bite, while bitewings carried out by inexperienced students revealed no difference between the methods. Both reproducibility and number of overlappings should be taken into consideration when bitewing filmholder techniques are used in epidemiological and longitudinal studies.

Patient preference for light-cured composite bite splint compared to heat-cured acrylic bite splint.

BACKGROUND: Heat-cured acrylic has been the most commonly used material for construction of bite splints. Although effective, its processing involves several steps and is time consuming. Furthermore, acrylic splints distort easily if not kept in water when not worn for long periods of time. A newly developed light-cured composite material is now being used for bite splint fabrication. The composite material offers benefits in ease and speed of construction, has minimal warping and distortion, and has proven patient acceptance. The aim of this study was to determine if patient satisfaction with the composite splint was as good as, or preferential to, the acrylic splint. METHODS: Both a composite and an acrylic bite splint were fabricated for each of 10 patients. The splints were worn alternately on a nightly basis and were adjusted as needed after the first week. After 3 weeks, each patient completed a questionnaire regarding the properties of each splint and any preferences they had in reference to fit, comfort, and other parameters of satisfaction. RESULTS: All of the patients were able to wear at least one of the splints comfortably. All 10 preferred the composite splint over the acrylic splint, agreeing that it felt more natural and was more comfortable to wear. CONCLUSIONS: The light-cured composite bite splint is preferable from the patient's perspective to the heat-cured acrylic bite splint. The composite splint is rapidly constructed on the original model, easily seated, and comfortably worn. Other properties of composite material also make it preferable for long-term use. Future studies are necessary to evaluate the functional differences between the composite and acrylic splint.

Comparison of bite size, biting rate and grazing time of beef heifers from herds distinguished by mature size and rate of maturity.

Sixteen-month-old heifers from herds having known genetic growth patterns were compared for differences in grazing behavior in a 3-yr study. Treatments were heifers from four size-maturity groups defined by the mature size and maturing rate of cow herds in which they originated. Average growth curve parameters indicating mature BW and rate of maturing in these cow herds were 387 kg and .19%/d for treatment Group I; 413 kg and .18%/d for Group II; 468 kg and .15%/d for Group III; and 589 kg and .16%/d for treatment Group IV. Data were from three heifers per treatment group grazing Midland bermudagrass during June and July observation periods. With the exception of the Group II vs Group III comparison, bite size increased with current or mature BW. Biting rate values were similar for all treatment groups but lower than those previously reported on other grass swards. Grazing time increased (P less than .01) in treatment groups defined by larger mature BW. Differences in grazing time for Group IV vs the other treatments and Group I vs Group II and Group III were observed repeatedly; the Group II vs Group III comparison was significant in one period during each of the 3 yr. Diurnal variations in grazing patterns among the treatments were observed. Period of observation affected (P less than .001) bite size and grazing time. These effects were not associated with month but could best be explained by differences in forage height and total mass. Forage availability had a direct influence on bite size, and a compensating effect of longer grazing time with smaller bite size was demonstrated as a regulator of intake. Differences in ingestive behavior were associated with genetic growth patterns in cattle.

Dog bites to the male genitalia: characteristics, management and comparison with human bites.

Dog bites to the external male genitalia occur infrequently. We present 4 new cases and review 4 others described previously. Victims tend to seek medical care quickly. Thus, morbidity is directly related to the severity of the initial wound and delayed infectious complications appear to be minimal. Guidelines for management include irrigation, debridement as necessary, empiric antibiotics, consideration of tetanus and rabies immunization, and primary wound closure or surgical reconstruction. The differences between dog bites and human bites to the genitalia--primarily interval to presentation and subsequent likelihood of infection--are summarized. Measures to prevent dog bites are discussed.

Clinical observations of mosquito bite reactions in man: a survey of the relationship between age and bite reaction.

To evaluate the mechanism of mosquito bite reaction in man, the reaction to Aedes albopictus was observed in 162 subjects ranging in age between 1 to 68 years old. Bite reactions were found to consist of both an immediate and a delayed reaction. The eruption and time course of the immediate reaction were consistent with type I hypersensitivity. The eruption and time course of the delayed reaction were consistent with cutaneous basophil hypersensitivity. Positive rates of immediate reaction increased from early childhood to adolescence and decreased with age from adulthood. The appearance and intensity of the delayed reaction decreased with age. Mosquito bite reactions in human beings exposed continuously and regularly are known to change from stage 1 to stage 5 (stage 1; no reaction, 2; delayed reaction only, 3; immediate and delayed reaction, 4; immediate reaction only, 5; no reaction). Analysis of the relationship between age and bite reaction in this study indicated that the principle held true even when the exposures were irregular or at random.

Use of a mouth gag instrument to facilitate bite block insertion and prevent finger and probe bites during transesophageal echocardiography.

Transesophageal echocardiography greatly enhances the examination of patients difficult to image transthoracically. While of low patient risk, a potential for harm from human bites to the echocardiography staff and to the transesophageal probe remains, particularly when dealing with uncooperative patients. This risk potential prompted implementation of additional anti-bite protection in our universal precautions policy beyond use of a standard mouth guard. A mouth gag instrument was modified by placing latex rubber tubing over the instrument blades. This instrument was inserted into the mouth and set in an open position giving the operator safe access for probe and mouth bite guard insertion. This technique improved access to the patient's mouth and visualization of probe insertion without the mouth bite guard. The mouth gag instrument provided an insertion of the transesophageal probe in impaired or otherwise uncooperative patients, which was safer for the patient, laboratory staff, and the probe itself.

Swinglock removable partial denture and biting forces in partially edentulous patients. Comparison of individual biting forces with and without swinglock removable partial denture.

Several studies have shown that swinglock removable partial dentures are effective for stability of the abutment teeth and the surrounding tissues including alveolar bone. This efficacy has been thought to be due to the dynamic structure of the swinglock attachment. Individual biting force was measured to determine the physiological efficacy of teeth splints by use of the attachment. The results showed that individual biting forces with the swinglock removable partial denture were 10-25% higher than those without the denture. Furthermore, statistical analysis showed that the individual biting forces with the swinglock removable partial denture were significantly higher. The swinglock attachment can stabilize partially edentulous dentition by splinting all residual teeth. In addition, when physical forces are applied to the abutment teeth and the artificial teeth, this attachment can deliver and distribute the stress to the other abutment teeth and alveolar mucosa. The present findings suggest that the swinglock attachment augments the ability to withstand physical forces such as those occurring during biting and mastication.

Quokka bites. The first report of bites from an Australian marsupial.

OBJECTIVE: To describe the incidence and natural history of bites from the quokka, a small wallaby. DESIGN: A prospective case series. SETTING: Rottnest Island Nursing Post, a small hospital staffed by registered nurses on call 24 hours a day, located on Rottnest Island 18 km off the coast of Western Australia near Perth. PATIENTS: All patients presenting after a bite from a quokka. RESULTS: Seventy-two patients (30 males and 42 females) presented after a bite. All but two patients were patting or feeding a quokka at the time of being bitten, and all but two were bitten on a finger or the thumb. Sixty-one per cent of patients were followed up; all wounds healed without complications. No wound pathogens were cultured from either wound swabs or swabs of the mouths of quokkas. CONCLUSIONS: Bites from quokkas heal without complications, usually in two to three weeks. Simple first aid and tetanus prophylaxis where appropriate are all that is required. Antibiotics are not indicated.

Dog-bite injuries at the Animal Bite Clinic of the Thai Red Cross Society in Bangkok.

Canine rabies remains a public health problem in Thailand and other developing countries. This study of animal bites at the Animal Bite Clinic at the Queen Saovabha Memorial Institute revealed that: (1) The majority of patients were bitten by dogs and the time of the attack was mostly during the day. (2) School-aged children are at the highest risk for animal bites. (3) The most common site of injury are the legs and foot (64.2%), with the second most common site being the hands and fingers (21.2%). (4) Only 48 per cent of patients received rabies vaccine 1-2 days after being exposed. There was considerable delay before the rest received treatment. Solving Thailand' s rabies problem depends on control of canine rabies and educational campaigns. Public education must be an integral part of efforts to decrease the incidence of animal bites and assurance that they are managed properly.

Electropalatographic and cephalometric assessment of tongue function in open bite and non-open bite subjects.

Anterior open bite (AOB) and tongue thrust swallowing are frequently associated, but the relationship between the two remains unclear. Electropalatography (EPG), which is used in speech pathology to measure dynamic tongue function for diagnostic, therapeutic, and research purposes, is a suitable technique for the investigation of this relationship. The present clinical study examined the dentofacial pattern and tongue function in AOB and non-open bite children. EPG recordings of speech and swallowing, and lateral head radiographs were obtained from eight 10-year-old boys with tongue thrust swallowing behaviour and AOB, and from eight age-matched non-open bite controls. Analysis of data from the two groups indicated that although differences were small, the open bite children displayed trends for longer face morphology and greater upper incisor proclination, less consistent production of closures during speech, a more posterior pattern of EPG contact, and relatively sparse EPG contact during swallowing. The discovery of differing patterns of contact for the /d[symbol: see text]/ and /t[symbol: see text]/ phonemes indicates that these should be included when speech is used to test for the presence of fronted tongue behaviour.

Where to treat? Is the habitual bite the best functional bite relationship?

One important consideration for any dental treatment involves evaluating the relationship of the mandible to the maxilla. Is the habitual bite that the patient possesses the best functional bite? There are a multiplicity of factors that must be considered in this evaluation before the doctor determines whether to treat to the patient's habitual bite position, or should a better bite position be determined.

[The use of spring-loaded posterior bite-block in the treatment of open-bite].

The treatment objectives of open-bite cases which occurs as a result of the excess vertical growth of nasomaxillary complex, increase in the upper and lower posterior vertical dentoalveolar development, downward and backward growth of the mandible are restraining of the growth capacity of these regions and leading the growth of the mandible on the horizontal plane. One of the treatment alternatives of these cases is the spring-loaded posterior bite block; a functional orthopedic appliance. In this case report which the effects of spring-loaded posterior bite block therapy on craniofacial and dentoalveolar structures have been shown; three cases having chronological ages of 9 years 8 months; 10 years 4 months and 10 years 1 month were presented and the treatment results were discussed. The common effects of spring-loaded posterior bite-block therapy observed in three cases are; the restraint of the vertical growth of the maxilla and of both lower-upper posterior dentoalveolar structures, change in the growth pattern of the mandible from vertical towards horizontal plane.

Vascular lesion in a patient of chronic active Epstein-Barr virus infection with hypersensitivity to mosquito bites: vasculitis induced by mosquito bite with the infiltration of nonneoplastic Epstein-Barr virus-positive cells and subsequent development of natural killer/T-cell lymphoma with angiodestruction.

This report describes a vasculitis and subsequently developing angiodestructive lymphoma in an 11-year-old Japanese-Filipino girl exhibiting mosquito allergy with the background of chronic active Epstein-Barr virus (EBV) infection. She developed necrotic skin ulcer at the site of mosquito bite, and histopathological examination revealed EBV-positive mononuclear cell infiltration throughout the wall of small-sized muscular artery. These EBV-positive lymphoid cells were oligoclonal in Southern blot analysis for EBV terminal repeats. Effectiveness of steroid therapy also supports the nonneoplastic nature. Approximately 1 year later, she developed progressive large skin ulcer without mosquito bites. Microscopically, the angiocentric or angiodestructive pattern of EBV-positive atypical cells supported the diagnosis of extranodal natural killer/T-cell lymphoma. Southern blot analysis revealed the monoclonal neoplastic nature of EBV-positive cells. In contrast to the primary mosquito bite lesion, natural killer/T-cell lymphoma cells exhibited the higher expression of EBV latent membrane protein 1 mRNA and the apparent protein expression detected by immunohistochemistry.

A case of exaggerated mosquito-bite hypersensitivity with Epstein-Barr virus-positive inflammatory cells in the bite lesion.

We describe a unique patient with mosquito-bite hypersensitivity who had extremely high titres of Epstein-Barr virus antibodies. For many years he developed intractable ulcers on the sites of mosquito-bite. Epstein-Barr virus infection was detected in almost all inflammatory cells in the ulcers and in the peripheral blood lymphocytes by using in situ hybridization to Epstein-Barr virus-encoded small ribonucleic acids and by polymerase chain reaction to Epstein-Barr virus DNA. The inflammatory cells in the ulcers were positive for T-cell marker. Our results suggest that the Epstein-Barr virus infection in T cells may participate in the pathogenesis of exaggerated mosquito hypersensitivity and in delayed healing of ulcers on the sites of mosquito-bite.

Ecology of the biting midge Leptoconops albiventris in French Polynesia. I. Biting cycle and influence of climatic factors.

The diurnal biting cycle of Leptoconops albiventris de Meijere (Diptera: Ceratopogonidae) is described from beaches of Nuku-Hiva, French Polynesia. Biting activity increased during the morning, diminished during the afternoon and was sufficiently intense to constitute a nuisance throughout the whole day. Correspondence Analysis indicated that climatic factors influenced biting activity. Activity was initiated by and positively associated with sunshine, whereas high temperatures, increased wind speed and rainfall were factors limiting activity. Decreased density of females during the dry season and their low capacity for dispersal were considered potentially advantageous with respect to control.

Biting rates and developmental substrates for biting midges (Diptera: Ceratopogonidae) in Iquitos, Peru.

Biting midges (Diptera: Ceratopogonidae) were collected at 16 periurban and rural sites around Iquitos, Peru, between 17 October 1996 and 26 May 1997. Culicoides paraensis (Goeldi), the principal vector of Oropouche virus, was the most commonly collected species (9,086 flies) with Culicoides insinuatus Wirth & Blanton second (7,229 flies). Although both species were collected at all sampling sites (linear (distance surveyed approximately 25 km), C. paraensis dominated at northern collection sites (> 90%), whereas C. insinuatus prevailed at southern collection sites (> 60%). C. paraensis were collected from human sentinels at a constant rate throughout daylight hours, at similar rates during wet and dry months, and regardless of rainfall. Larval developmental substrates for C. paraensis included decaying platano (Musa x paradisiaca L. [Musaceae]) stems, stumps, flowers, fruits, and debris beneath platano trees as well as from soil beneath a fruiting mamay (Syzygium malaccense Merr. & Perry [Myrtaceae] ) tree and organic-rich mud along a lake shoreline. C. insinuatus adults likewise emerged from decaying platano and organic-rich mud along a lake shoreline, but also from debris accumulated in the axils of aguaje (Mauritia flexuosa L. [Palmae]) fronds and decaying citrus fruit. Despite high numbers of biting adults near putative substrates, adults of neither species emerged from other decomposing plant material, soil, phytotelmata, or artificial containers. Because both species of biting midges emerged in high numbers from all parts of platano (ubiquitous in Iquitos), it will be challenging to control them through sanitation.

[Tarantulas bite: two case reports of finger bite from Haplopelma lividum].

The risk of envenomations by venomous exotic spiders have not been well recognized in Japan. Two cases of finger bite from Asian pet tarantula, Haplopelma lividum (Cobalt blue), are reported. In both cases, initial severe pain and inflammatory signs were completely healed with only symptomatic treatments within several hours. In one case, arthritic stiffness lasted for a few weeks following bite but resulted no permanent deficit. Bites from Haplopelma lividum seemed relatively harmless like other various tarantulas, although the composition of the venom has been unknown.

[A case of bite by Naja Naja Naja in India. Problems posed by the treatment of snake bites].

The author reports a case of poisonous snake bite by Naja naja naja, in India. The patient recovered rapidly after treatment by antivenom serum. He emphasizes the importance of prompt intravenous injection of serum. Serum is less active for viper bites, and should be injected even more rapidly. However, in France, some authors prefer Heparin for treating French viper bites. Further studies are needed to clarify this therapeutic problem.
