Abstract:
The elevation of the pharynx and larynx at swallowing in 10 patients with a defective relaxation of the cricopharyngeal muscle, was compared with that in 10 normals. The pharynx and larynx moved higher among patients with a defective relaxation of the cricopharyngeal muscle. Therefore, it can be concluded that a defective relaxation of the cricopharyngeal muscle at swallowing has no relationship to a defective pharyngo-laryngeal elevation. References

Abstract:
Abstract The pharynx of Caenorhabditis elegans is a nearly self-contained neuromuscular organ responsible for feeding. To identify genes involved in the development or function of the excitable cells of the pharynx, I screened for worms with visible defects in pharyngeal feeding behavior. Fifty-two mutations identified 35 genes, at least 22 previously unknown. The genes broke down into three broad classes: 2 pha genes, mutations in which caused defects in the shape of the pharynx, 7 phm genes, mutations in which caused defects in the contractile structures of the pharyngeal muscle, and 26 eat genes, mutants in which had abnormal pharyngeal muscle motions, but had normally shaped and normally birefringent pharynxes capable of vigorous contraction. Although the Eat phenotypes were diverse, most resembled those caused by defects in the pharyngeal nervous system. For some of the eat genes there is direct evidence from previous genetic mosaic and pharmacological studies that they do in fact affect nervous system. In eat-5 mutants the motions of the different parts of the pharynx were poorly synchronized. eat-6 and eat-12 mutants failed to relax their pharyngeal muscles properly. These pharyngeal motion defects are most easily explained as resulting from abnormal electrical excitability of the pharyngeal muscle membrane.

Abstract:
The structure of the pharynx was studied in the genera Didymorchis, Diceratocephala, Temnocephala, and Craspedella, using light microscopy, silver nitrate staining, and transmission electron microscopy. Based on these data, evolution of this organ within the Temnocephalida is analysed. In addition to the specific pattern of muscle fibres in the walls of the pharynx known from earlier studies, three other features characteristic of the pharynges of temnocephalids were found: (1) multisyncytial organization of the pharyngeal epithelium, (2) the presence of type 1 sensory receptors, and (3) muscle fibres incorporated into the epithelium of the pharynx. Features deduced to be characteristic of the pharynx in primitive temnocephalids are (i) the presence of three types of sensory receptors with specific morphologies and locations in the pharynx, (ii) the presence of a bundle of muscle fibres that traverses the epithelium surrounding the anterior margin of the pharynx, (iii) characteristic lamellation of the epithelium of the pharynx proper, and (iv) a narrow syncytium nesting the openings of the pharyngeal glands and forming deep invaginations into which the gland ducts open. The most prominent tendencies in the evolution of the pharynx are reinforcement of the pharyngeal musculature (related to the mode of feeding) and reduction in the number of syncytia.

Abstract:
The work presented in this thesis concerns neurophysiology and pharmacology of the oesophageal afferent pathways involved in oesophago-pharyngeal reflexes and oesophageal nociception. Disturbances of reflexes governing contractile and relaxation responses of the upper oesophageal sphincter (DOS) are likely to be implicated in the pathophysiology of conditions involving excessive oesophago-pharyngeal regurgitation, impaired oesophageal clearance, and an abnormal belch reflex. Visceral hypersensitivity, a heightened perception of gastrointestinal sensation is frequently observed in functional gastrointestinal disorders and provides compelling evidence that it plays an important role in the pathogenesis of functional heartburn and non-erosive reflux disease. The work in this thesis explores the neurophysiology, pharmacology and pathophysiology of oesophago-DOS reflexes in humans by experimentally inducing DOS relaxations in healthy controls and patients with reflux laryngitis, and by recording DOS motor responses during spontaneous oesophago-pharyngeal regurgitation. Nociception was assessed by measuring oesophageal sensitivity to electrical stimulation and oesophageal acid perfusion in healthy controls, which was then compared with several heartburn populations (functional heartburn, erosive and non-erosive reflux disease). Additional studies were performed to evaluate the potential role of intraluminal impedance in defining antegrade bolus flow through the pharyngo-oesophageal segment during swallowing as a prelude to the adaptation of the technique to find a more accurate method for the detection of oesophago-pharyngeal regurgitation. The main findings from this work are as follows. 1) Mucosal lignocaine-sensitive afferents mediate the distension-induced oesophago-DOS relaxation reflex and lignocaine insensitive, presumably muscular mechanoceptors, mediate the distension-induced oesophago-DOS contractile reflex. The latter reflex is also upregulated by oesophageal acidification indicative of a possible protective mechanism. 2) Prolonged studies in patients with proven oesophago-pharyngeal regurgitation demonstrated that the most common mechanism of oesophago-pharyngeal regurgitation is a transient, non-swallow related, relaxation of the DOS. 3) Experimental evaluation of the oesophago-DOS relaxation reflex revealed that it is upregulated in patients with reflux laryngitis, suggesting that the aberrant afferent signalling in the oesophagus may be a contributory factor mediating oesophago-pharyngeal regurgitation. 4) Measurement of oesophageal sensory thresholds in response to electrical stimulation and acid perfusion revealed that all patients, irrespective of the presence or absence of mucosal injury, exhibit acid-induced hypersensitisation. 5) The viscro-somatic referral pattern of acid- and electrically-induced chest pain is increased in patients with functional heartburn and non-erosive reflux disease. These findings support the hypothesis that central sensitisation of nociceptive pathways may contribute to symptom reporting in these heartburn populations.

Abstract:
Despite the advance in modern oncology, there was limited improvement over the survival outcome of head and neck cancers. Until the discovery of the etiological association between Human Papillomavirus (HPV) and oropharyngeal cancer, an accelerated evolution in the field of head and neck oncology began. This viral-related tumor has ignited tremendous effort in American and European countries to explore the optimal treatment approaches. In contrast, the paucity of comprehensive and robust studies commonly exists in many Chinese and Asian countries. Little is known about the current situation of HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) in Hong Kong. This retrospective local multi-institutional study attempted to explore the HPV-associated OPSCC in Hong Kong from various aspects, including demographics, risk factors, clinical and histological features, molecular profile, as well as clinical outcomes. Finally, attempts were made to determine any predictive factors to stratify high-risk patients in this distinct disease entity and explore the most appropriate detection algorithm of the biologically active HPV infection in our locality. With the support from the Hong Kong Cancer Registry and nine public hospitals, 141 (43.3%) of 326 newly diagnosed OPSCC in the whole population of Hong Kong between 2005 and 2009 were recruited. Inclusion criteria were histologically proven OPSCC with tumor specimens available for prospective laboratory tests. Those with non-SCC, non-oropharyngeal in origin and incomplete clinical records were excluded. Prospective HPV PCR and genotyping, and immunohistochemical staining with p16, p53, cyclin D1 and HER-2 were performed. Univariate and multivariate analyses were performed to assess the correlations between various parameters and HPV-associated OPSCC. Epidemiologically, based on the combined positivity in HPV PCR and p16, the prevalence of HPV-associated OPSCC was 22%. Thirty (96.8%) of thirty one were HPV-16, the remaining one was HPV-18. In the univariate analysis, this cancer directly correlated with female gender (p=0.014), younger age (p=0.012), non-smoker (p=0.02), non-drinker (p=0.06) and early primary tumor (p=0.001). Histologically, basaloid differentiation (p<0.001), non-keratinization (p=0.007) and high tumor infiltrating lymphocyte (TIL) level (p<0.001) showed significant correlations. A distinct molecular profile was identified, with p16 positivity noted in all cases (p<0.001), few of p53 (p<0.001) and cyclin D1 positivity (p<0.001) and absence of HER2 over-expression. Significantly superior prognosis was demonstrated in HPV-associated OPSCC. The 5-year overall and disease specific survivals were 67.0% and 88.6% compared with 27.8% (p<0.001) and 41.3% (p<0.001) in the non-viral counterpart respectively. Other good prognostic factors identified for OS and DSS included early primary disease (T1/T2) (p=0.02; p=0.001), absence of distant metastasis (both p<0.001), high TIL level (both p<0.001), p16-positivity (p=0.002; p=0.003), non-smoker (p=0.021; p=0.014). In the multivariate analysis, the HPV-associated tumor (HR: 0.28; 95% CI: 0.08 – 0.93; p=0.038), early primary tumor (HR: 0.52; 95% CI 0.30 – 0.89; p=0.017) and absence of distant metastasis (HR=0.15 95% CI: 0.07 – 0.3; p<0.001) were associated with lower risk of death from any causes after controlling other confounding factors. Most importantly, high TIL level in HPV-associated OPSCC patients was associated with 89% (HR: 0.11; 95% CI: 0.02 – 0.61; p=0.012) lower risk of death from any causes than those with low TIL level, but not present in non-HPV counterpart. In addition, either HPV PCR complemented with typical high-risk genotyping results or p16 IHC positivity complemented with HPC PCR positivity using specific designed primers were two reasonably sensitive and specific detection algorithms based on the local genotypic distribution of this disease. In summary, this is the first most comprehensive and robust local study indicating the importance of HPV-associated OPSCC in Hong Kong. It successfully illustrated various distinctive characteristics of this viral-related cancer. Additionally, it has suggested a potential predictor to identify the minority with more aggressive diseases and the most effective laboratory detection algorithms in this locality. It definitely facilitates the next step in exploring this disease via larger and prospective trials in coming future.

Abstract:
Cet essai de geographie du cancer du cavum a pour but de localiser les "airs pathogenes" au maroc, et ce en le situant par rapport au monde et au maghreb. Le nord du maroc est le plus touche, il est aussi le mieux desservi par le systeme de soins. Nous pouvons inverser et conclure que le systeme de soins a mis au jour le "probleme" du cancer du cavum. La population touchee est principalement masculine, relativement jeune et distribuee presque a parts egales entre le milieu rural et le milieu urbain. Le malade appartient aux classes sociales defavorisees, que ce soit au niveau du pays ou au niveau d'une ville, telle que rabat. Affiner l'analyse dans la zone la plus touchee serait d'un grand interet mais les donnees disponibles actuellement ne permettent pas encore de le faire. L'etiologie du cancer du cavum au maroc est difficile a cerner; car on ne dispose d'aucune enquete epidemiologique. Cependant les recherches menees dans le sud est asiatique ont permis de degager les grandes lignes de l'etiologie de la maladie dans ce pays. Neanmoins, la relation entre le cancer du cavum et l'environnement semble tres etroite. D'ou l'importance des enquetes a mener aupres des malades et au sein des regions a risque
The goal of this essai of geography of nasopharyngeal cancer is to localize the pathogenic areas in morocco, underlining its situation as compared to the world and maghreb. The north of morocco is the most affected althoug it is the best served by health care system. We can invert and conclued that health care system has brought up the problem of nasopharyngeal cancer. The population affected is principaly male, relatively young and almost equaly distributed between the rural and urbain areas. The patient belongs to the underpriviledge social groups on the country's level as well as in the level of centers-such as rabat-. To ripen scale analysis in affected areas would have a great interest but available data is not sufficient presently to advice this goal. The etiology of nasopharyngeal cancer is uneasy to delimit because no epidemilogical study has been fulffild. However the research made in south east asia have permetted to define the out lines of the etiology. Nevertheless, the relation between nasopharyngeal cancer and the environment seems to be linked through a tight relationship. Thus it is important to lead studies on the patients and within risk areas

Abstract:
This work was aimed to study numerically the food bolus flow through the pharynx. Using a 2D geometry obtained elsewhere, a three-dimensional code has been developed for the study exclusively of the fluid inside the pharynx considering a non-Newtonian fluid. Three-dimensional geometries of the pharynx at ten different instants using high-order polynomials were generated. For any time range investigated, the shape of the pharynx was introduced into a Cartesian grid by using the technique of immersed boundaries and three-dimensional interpolations. The geometry evolved within this grid and the equations of fluid mechanics were numerically solved. The effect of the pharyngeal walls on the fluid was modeled from the theory of elastic membranes. Flow fields in terms of the axial velocity, pressure, shear rate and viscosity were obtained.

Abstract:
Structures and functions of a mosquito’s pump system were investigated experimentally to clarify the mechanistic aspects of this optimized bio-pump. The three-dimensional strucure of the pump that was reconstructed by 1500 slices of the mosquito’s head was obtained using a histopathological method. The mosquito’s pump motion is predictable, and the pump volume can be estimated by the three-dimensional structural observations. The pump volume of the pumps, an oral cavity pump and pharynx pump, were estimated as being 7.92×10−4mm3, 63.3×10−4mm3 respectively. The frequency of the mosquito’s pumps was predicted to be 2.09–16.7 Hz, and was estimated using the pump volume and the volumetric blood flow rate. The motion of the mosquito’s pumps was visualized directly by an x-ray phase contrast imaging method using synchrotron radiation. It was found that the mosquito’s pumps (i.e., the oral cavity pump and the pharynx pump) worked alternately with a 4.23 Hz pump frequency. Moreover, the phase difference of each pump was almost 0.5, suggesting that the mosquito’s pumps worked in opposite phases. In addition, the mosquito’s pumps were found to work as a inline pump, which is suitable for increasing the pressure head of pump.

Abstract:
Cystic lesions of neck containing thymic tissue are rare and usually difficult to diagnose. Postulated hypothesis for this entity is the persistence and/or degeneration of thymopharyngeal duct derived from pharyngeal pouch endoderm. We report a unique case of persistent thymopharyngeal duct which was diagnosed antenatally at 30 weeks’ gestation, and it preserved its connection with the pharynx. Postnatal radiological studies were non-specific and misleading, and diagnosis was confirmed by histological examination of the excised specimen.
