Post-Traumatic Palatine Odontogenic Abscess: About 2 Cases

Introduction: Palatal abscess or cellulitis of dental origin is a rare clinical form of circumscribed cellulitis that can sometimes pose a diagnostic problem. It is the consequence of poor or non-treatment of dental caries or trauma. The aim of this study is to describe the clinical and therapeutic aspects of these two cases of palatal cellulitis of post-traumatic dental origin. Observation: The patients consulted for painful palatal swelling secondary to untreated dental trauma of the 21s. The diagnosis of palatal cellulitis was based on the inflammatory and fluctuating nature of the swelling. A probabilistic bi-antibiotic treatment and an incision and drainage associated with treatment of the portal of entry were carried out. Progression was favourable in both cases. Conclusion: Palatal cellulitis is a rare condition and can be prevented by systematic stomatological consultation after dental trauma. Diagnosis is clinical. However, CT scans are sometimes useful. The course is generally favorable with appropriate treatment.

Obstructive Tumor of the Palate in the Old Person: A Case Report

Introduction: Pleomorphic adenoma or mixed salivary gland tumor is a heterogeneous benign tumor of the salivary glands. The most common site is the parotid gland. Its extra-parotid locations, particularly in the accessory salivary glands, are rarer. We report a case of a pleomorphic adenoma of the posterior palate which posed management problems. Observation: This is an 85-year-old patient who consulted for a tumor of the posterior palate that had been evolving for 3 years. The examination revealed a globular tumor of the posterior palate extending beyond the midline by approximately 7 cm in long axis, shooting towards the oropharynx and hindering breathing, speech and eating, indicating a life-saving tracheotomy. A CT scan of the facial area revealed a well-circumscribed tumor at the expense of the soft palate, with multiple sites of bone lysis. The biopsy performed was in favor of a pleomorphic adenoma. The patient underwent total surgical excision of a huge tumor on the palate. The aftermath of the operation was marked by a loosening of the sutures with an oronasal fistula requiring the creation of an obturator plate due to the patient’s refusal to have another operation. Conclusion: Large pleomorphic adenoma of the posterior palate is a rare entity that can cause respiratory problems and surgical difficulties. His prognosis is generally good.

Palatability Testing of Oral Chewables in Veterinary Medicine for Dogs

For veterinary medications administered per os, animal health companies strive to develop highly palatable dosage forms that are voluntarily accepted by animals to improve compliance and convenience. Achieving high palatability is often complex and difficult even without the presence of an active ingredient. This work compared acceptance and preference studies, as standardized methods are not established for informing formulation development or for more routine testing. Formulation development was followed by an acceptance study completed with laboratory Beagle dogs. One acceptance study and one preference study were completed in mixed breed dogs, also laboratory-housed, to gain wider representation of dog breed and age. Through these studies, we have evaluated both formulation parameters and palatability study conduct. In general, more complex palatants that have appealing taste, smell, and mouth feel enhance voluntary uptake. However, dosage forms that are too chewy may not be freely consumed even with complex palatants. The addition of aroma can entice dogs to prehend the tablet, as observed in one preference study. Preference studies in the veterinary pharmaceutical field identify the preferred first choice or first prehend, but not which product will be routinely voluntarily and fully consumed. Acceptance studies with cross-over treatment groups are used to quantify the full consumption of a dosage form when a dog is not given two choices at once. Since all dogs in acceptance studies are offered all treatment groups throughout the study, a comparison between degrees of consumption could suggest that one formulation might be preferred over another.

Usefulness and limitations of taste sensors in the evaluation of palatability and taste-masking in oral dosage forms

The purpose of this review is to discuss the advantages and limitations of taste sensors in the evaluation of the taste of palatability of different oral dosage forms. First, we consider some ways in which the palatability of various pharmaceutical formulations including orally disintegrating tablets(ODTs) are tested using two different taste sensors. Second, we focus on the evaluation of palatability of ODTs. We compare the usefulness of three pieces of apparatus for estimating the disintegration time of ODTs. Finally, we compare the characteristics of the two taste sensors in the evaluation of palatability of various kinds of drug formulations.

Water Management for Improvement of Rice Yield,Appearance Quality and Palatability with High Temperature During Ripening Period

To clarify the optimal water management in large-scale fields under high temperatures at the ripening period,effective water managements during this period for improvement of yield,appearance quality and palatability were investigated.Compared with intermittent irrigation and flooded irrigation,the soil temperature with saturated irrigation remained low throughout the day,and the decrease rate of the bleeding rate of hills was the lowest.These results suggested that the saturated irrigation maintained root activity.For the three irrigation types,the number of spikelets per m2 and 1000-grain weight were similar,however,saturated irrigation resulted in significantly higher rice yield due to improvement in the percentage of ripened grains.The saturated irrigation produced a high percentage of perfect rice grains and thicker brown rice grain,furthermore,the palatability of cooked rice was excellent because protein content and hardness/adhesion ratio were both low.Thus,under high-temperature ripening conditions,soil temperature was lowered and root activity was maintained when applying saturated irrigation after heading time.The results indicated that saturated irrigation is an effective countermeasure against high-temperature ripening damage.

Mapping Quantitative Trait Loci for Palatability of Milled Rice

Quantitative trait loci (QTLs) controlling palatability in rice were identified using a set of 98 backcross inbred lines (BILs) population derived from a cross between a japonica variety Nipponbare and an indica variety Kasalath. The palatability scores of the population measured by RQ1/Plus Rice Analyzer, showed a continuous and transgressive segregative distribution with a range from 66 to 92. Four putative QTLs for palatability, qPAL-5, qPAL-7, qPAL-8a and qPAL-8b, were detected on chromosome 5, 7 and 8, and they accounted 7.83, 7.03, 11.58 and 7.19% of the total phenotypic variation, respectively. Three alleles qPAL-5, qPAL-7 and qPAL-8b from Kasalath increased the palatability score, whereas only one Nipponbare allele qPAL-8a increased the score . Eight transgressive lines in palatability were selected to make a comparison between phenotypic and genotypic classes. The result explained the possibility of positive QTLs pyramiding through marker-assisted selection of highly palatable rice.

Influence of Different Sources and Levels of Fat on Palatability of Tibetan Mastiff

In order to compare the palatability of Tibetan mastiff to different fat sources and fat levels, four kinds of raw lipid materials （ soybean oil, sunflower seed oil, chicken fat and butter） were selected to prepare five candidate diets with different fat source combinations and three different fat level combinations （6%, 10% and 14% ）. Ten healthy Tibetan mastiff adults were randomly divided into two groups. The intematianally useful double-pot cultivation design was employed to record the daily feed intake and preferred diet of each Tibetan mastiff, and further to calculate the intake rate. The butter group assumed higher feed intake and intake rate than the chicken fat group （P 〈0.01）, and the preferred diet as well （83%）. The feed intake and intake rate of chicken fat group was significantly higher than chicken fat and butter （ 1：1 ） combined group （ P 〈 0.01 ）. No significant difference was observed in the diet palatability of butter diet to Tibetan mastiff to different plant oil sources （ P 〉 0.05）. For various fat level combinations, the diet with highest fat content diet H23 assumed higher feed intake and intake rate than low fat diet H22 and H21 （P 〈0.05）. It is concluded that the palatability of butter diet to Tibetan mastiff is higher than chicken fat and its combined diet （ butter：chicken fat = 1：1 ） ; with fat level of 6% - 15%, high fat diet provides Tibetan mastiff a better palatability in comparison with low fat diet.

Evaluation of the Palatability of Dry Syrups and the Bitterness Intensities of Dry Syrups Mixed with Various Beverages

The purpose of this study was to evaluate the palatability of dry syrups for pediatric use by human gustatory sensation testing and the artificial taste sensor. The bitterness intensities of dry syrups mixed with various beverages were also evaluated using the taste sensor. Twenty dry-syrup formulations of antibacterial and anti-allergic drugs containing bitter active ingredients, frequently used in pediatric medicine in Japan, were selected for testing. The main factors influencing palatability were determined by factor analysis of data from human gustatory sensation testing using the semantic differential method. It was shown that the bitterness intensity of dry syrups in water could be predicted by the artificial taste sensor. The influence of different beverages (orange juice, milk or cocoa) mixed with the dry syrups was evaluated using the artificial taste sensor. Taste and texture were found to be the principal factors influencing the palatability of dry syrups. While the bitterness intensities of some dry syrups were increased by mixing with orange juice, the bitterness intensities of most dry syrups were decreased by mixing with milk or cocoa. This suggests that one or more constituents of milk or cocoa may reduce the bitterness intensities of dry syrups.

Palatability of Two Kinds of Rodenticides for Apodemus agrarius

[Objective]The paper aimed to compare the palatability of 0.005% brodifacoum bait and 0.005% bromodiolone bait for Apodemus agrarius.[Method]A.agrarius were divided into two groups：brodifacoum group and bromodiolone group,and each group was released with equal amount of poison bait and feed.The daily consumption and mortality of each group was recorded.[Result]The total consumption of poison baits in brodifacoum group and bromodiolone group were64.6 and 40.4 g,respectively.Mortality of A.agrarius was observed in two groups since the 3^rdday after administration,and A.agrarius died completely on the5^thday.The feeding coefficient of poison bait to feed in brodifacoum group was 1.47,and that in bromodiolone group was 0.69.[Conclusion]The palatability of 0.005% brodifacoum bait for A.agrarius was superior to that of 0.005% bromodiolone bait.

Nutritional Evaluation and Palatability of Major Range Forbs from South Darfur, Sudan

The nutritive value of rangelands in Southern Darfur, Sudan could be improved by introduction and multiplication of nutritious forbs with the objective of increasing livestock production in the area. The present study was conducted to evaluate the nutritive value and palatability of eleven range forbs collected at flowering stage from Gahzal Gawazat, Southern Darfur, Sudan using chemical analysis. The crude protein (CP) ranged from 6.8% in Oxygonum atriplicifolium with lowest digestible crude protein (DCP) 2.8% to 16.4% in Zornia diphylla with highest DCP 11.73%. The highest and the lowest crude fiber (CF) values were obtained in Commelina spp (56.4%) and Sesamum alatum (25.9%), respectively. NDF and DMI values were maximum and minimum for Zornia diphylla (44.9 and 2.67%) and Alysicarpus glumaceus (35.3 and 3.4%), respectively. The total digestible nutrients (TDN) ranged from 57.1% in Blepharis linariifolia to 69.3% in Tribulus terrestris with highest digestible energy (DE) in later while the lowest DE was obtained in Commelina spp (2.4%). The calculated in vitro organic matter digestibility (IVOMD) was highest for the Canavalia ensiformis (50.27%) and lowest value (43.17%) for Commelina spp. Zornia diphylla, Tribulus terrestris and Sesamum alatum showed highest nutritive value, while Alysicarpus glumaceus, Oldenlandia senegalensis and Chrozophora brocchiana showed highest palatability. It is concluded that these rangeland forbs are palatable and their CP and energy contents are sufficient to support different classes of livestock in South Darfur, Sudan.

Palatability of Water-Soluble Extracts of Protein Sources and Replacement of Fishmeal by a Selected Mixture of Protein Sources for Juvenile Turbot(Scophthalmus maximus)

Poor palatability is a limiting factor for replacing fishmeal with other protein sources in aquaculture. The water-soluble molecules with low molecular weights are the major determinants of the palatability of diets. The present study was conducted to investigate the palatability of water-soluble extracts from single protein source(single extract pellets) and the mixture of these extracts with different proportions(blended extract pellets) in juvenile turbot(Scophthalmus maximus). Then according to the palatability of blended extract pellets, an optimal mixture proportion was selected, and a new protein source made from raw protein materials with the selected proportion was formulated to replace fishmeal. Summarily, the palatability of single extract pellets for turbot was descendent from fishmeal to pet-food grade poultry by-product meal, wheat gluten meal, soybean meal, peanut meal, meat and bone meal, and corn gluten meal. Subsequently, according to the palatability of single extract pellets, 52 kinds of blended extract pellets were designed to test their palatability. The results showed that the pellets presented remarkably different palatability, and the optimal one was diet 52(wheat gluten meal: pet-food grade poultry by-product meal: meat and bone meal: corn gluten meal = 1:6:1:2). The highest ingestion ratio(the number of pellets ingested/the number of pellets fed) was 0.73 ± 0.03, which was observed in Diet 52. Then five isonitrogenous(52% crude protein) and isocaloric(20 k J g^(-1) gross energy) diets were formulated by replacing 0(control), 35%, 50%, 65% and 80% of fishmeal with No.52 blending proportion. After a 10-weeks feeding trial, a consistent feed intake was found among all replacement treatments. Replacement level of fishmeal up to 35% did not significantly influence final body weight, specific growth rate, feed efficiency ratio, and protein efficiency ratio of turbot. Therefore, the water-soluble extracts of protein sources play an important role in improving the palatability of non-fishmeal protein sources in aquafeed.

Assessment of Two Years of Free Surgical Treatment of Cleft Lip, Palate and Alveolar (CLPA) in the Maxillofacial Surgery and Stomatology Department of the Hospital University of Treichville-Abidjan

Introduction: Cleft lip, palate and alveolar (CLPA) are congenital malformations of the face due to a defect in the fusion of embryonic buds during the first weeks of embryogenesis. These malformations affect the upper lip, the alveolar bone and the palate. The incidence in Africa ranges from 1/2000 to 1/500 births. Their multidisciplinary management is long and costly. Thus, the help provided by humanitarian organisations during free care campaigns is welcome. Materials and Methods: This is a retrospective descriptive study conducted from August 2014 to July 2016 in the Maxillofacial Surgery and Stomatology Department of the Treichville University Hospital in Abidjan, Côte d’Ivoire. The objective was to describe the epidemiological, clinical and therapeutic aspects of CLPA during a humanitarian campaign for free care. Results: 51 cases of CLPA were operated on. Males were involved in 54.9% of the cases, i.e. a sex ratio of 1.2. The average age of the patients at the time of the operation was 3.44 years with extremes of 3 months and 52 years. Patients with low socioeconomic status represented 84.3% of the cases. Cleft lips (31.4%) and cleft palates (33.33%) predominated. For cleft lips, unilateral forms were the most frequent (73.5%) and the left side was most often affected (59.2%). The most common surgical techniques used were MILLARD cheiloplasty for cleft lips (79.36%) and Dorrance pushback for cleft palates (78.05%). The postoperative course was simple in the majority of cases (80.47%). Patients and/or parents were satisfied with the postoperative results in over 90% of cases. Discussion: Cleft lip and palate are common. Their management by humanitarian missions through mass campaigns allows us to receive a large number of patients affected by this pathology who are treated with a high satisfaction rate. Conclusion: The characteristics of cleft lip and palate in this study are in many respects identical to those described in the literature, but with some differences specific to Africa, notably the absence of antenatal diagnosis and the advanced age at the time of treatment.

Penetrating soft palate injury by lollypop candy stick

Incidents of soft palate injury or laceration caused by unintended movement when holding a sharp object in the mouth in the pediatric population are usually rarely reported.Here we report a case of soft palate laceration in a child due to a lollypop stick tip.

Comparison of the Palatability of a New Flavoured Drontal^(■) Plus Tablet(Drontal^(■) Plus Treat 10 kg)and Milbemax^(■) Chewable Tablets When Presented to Privately Owned Dogs

There is an increased need for highly palatable oral dosage forms for dogs and cats, especially in the case of regular or chronic medications. To meet this need of easy application, the original Drontal®Plus tablet, a broad-spectrum anthelminthic, was optimized using a novel formula. A field study was conducted to evaluate the palatability of this new Drontal®Plus formula in comparison to a positive control product (Milbemax®Chewable Tablets) with a well-known high palatability. The study also aimed to get a palatability claim which necessitates the conduct of appropriate studies. 150 privately owned dogs of 38 pure or mixed breeds, six months to twelve years old, and with a weight range of 5 to 50 kg were included. The study was based on a cross-over design, and a standardized acceptance test was used to evaluate and compare the palatability of the two medications. In this study 88% of dogs voluntarily consumed Drontal®Plus Treat 10 kg, and 86.7% accepted Milbemax®Chewable Tablets. In the majority of cases (IVP: 98%, CP: 95%) the tablets were taken directly from the owner’s hand. The new Drontal®Plus tablet showed a high palatability compared to the Milbemax®Chewable Tablets when used in a household study design with privately owned dogs.

Rhinoplasty in Cleft Lip and Palate

Various surgical techniques and approaches have been described to repair cleft nose deformities. It is necessary to consider that since it is a congenital deformity, surgical management must consider the patient’s growth process, as well as the healing itself from the surgery. The present study aims to evaluate an alternative solution to secondary rhinology, aesthetic, and functional alterations to unilateral or bilateral cleft lift palate to minimize deformities and ensure good results. 11 patients were studied between 1995 to 2002, ten male and one female. In 8 cases, the patients had a history of cleft lip and palate on the left side, 2 patients with cleft lift palate on the right, and 1 patient with bilateral cleft lip and palate. 100% of the patients increased their naso-labial angle. This improved their appearance and structure, starting from a preoperative arithmetic mean of 39 degrees to a postoperative arithmetic mean of 96 degrees. Such intervention increased the naso-labial angle by 57 degrees. At the base of the nose, it was possible to improve the inclination of the alar line (line B) in 10 of the cases with a variation of 2 to 3 mm in relation to the perpendicular line A and only one case remained with the same inclination.

父母年龄和先天性唇(腭)裂患儿之间的关系

为分析出唇(腭)裂疾病的发生概率和其父母年龄的关系,通过采用Logistic回归分析675例非综合征性唇(腭)裂患者,包括404例唇(腭)裂(cleft lip with/without cleft palate,CL±P),271例腭裂(isolated cleft palate,CP),并记录父母生育年龄。根据裂隙的严重程度分为两组:唇(腭)裂(CL±P)及腭裂(CP)。单侧裂分为左侧裂及右侧裂。研究发现在唇(腭)裂(CL±P)中,父母双方年龄都大时,后代患唇(腭)裂(CL±P)的风险要比父母双方都年轻的高很多。在腭裂(CP)中,父母年龄大比父母年轻的后代更易患腭裂,但是无统计学意义。同时分析父母年龄和左右侧裂之间的关系,发现父母年龄和左右侧裂统计学无意义。随着父母年龄的增长,后代患唇(腭)裂的风险越大,进一步的分析表明,只有当父母双方的年龄都很高时,这种风险才会增加。
