Background: The submandibular gland is the second largest major salivary gland and weighs 7–16 gr. The gland is located in both sides of the face, at the same level of the body of the jaw, in the submandibular triangle, The submandibular duct or Wharton’s duct exits anteriorly, coursing deep to the lingual nerve and medial to the sublingual gland, the main excretory duct of the submandibular gland, whose diameter is of 2 to 3mm and approximately 4–5 cm long. It empties lateral to the lingual frenulum through a papilla in the floor of the mouth behind the lower incisor tooth. The purpose of this study is determine the morphologic features and describe an unusual anatomical variation of the path of the submandibular duct. Methods and Findings: A total of 17 cadavers were used for this study in the Morphology Laboratory at the University of Pamplona. In a cadaver were findings: The excretory duct of the left submandibular gland had an external location that ascends and crosses vertically off the body of the mandible, in its termination it is divided in four ducts that had separate openings into the oral cavity upon a small papillas independent, opposites to the first and second lower molar Crown. Conclusions: Awareness of potential variations of the excretory ducts of the salivary glands can aid in the accurate diagnosis and treatment of patients with salivary conditions as well as help surgeons avoid further complications or duct lacerations during surgical procedures.

Introduction: The submandibular gland is located bilaterally in the submandibular triangle. The main submandibular duct or Wharton’s duct, runs with lingual nerve to open in the sublingual papilla at the side of frenulum of the tongue. The aim of this study was to demonstrate the unusual variations of accessory submandibular duct in comparison with main submandibular salivary gland duct. Material & Methods: Nineteen cadavers were dissected to study the submandibular salivary duct. Results: 15.7% incidence of variations were observed. We found that one submandibular region was having unusual path of accessory duct, it emerged from superficial part of the gland and crossed the superficial surface of mylohyoid muscle and bifurcated into two branches. These bifurcated branches of duct pierced the mylohyoid muscle to pass between mylohyoid and hyoglossus muscle. One branch of bifurcated accessory duct opened through papilla in the floor of the mouth behind the lower incisor tooth and second branch of the bifurcated duct anastomosed with the main duct (Wharton’s duct) to open in sublingual papilla. Wharton’s duct of this side followed its normal path to open in the sublingual papilla. Two specimens of submandibular region was observed with duplication of submandibular duct in each submandibular gland. One was main duct and second was accessory duct. Both ducts emerged separately from the deep part of submandibular gland and ended independently into sublingual papilla. Conclusion: Reporting of these variations are important for diagnostic imaging, anatomical teaching and to help surgeons while operating in this region.

The aim was to determine the morphometric parameters of the maxillofacial area of Omsk young men of 18-20 years of age according to the teleroentgenography of the head (in a lateral projection), taking into account the indicators of cephalometry and anthropometry, to identify regional constitutional features of quantitative values.Material and methods. A cephalometric and somatometric examination of 26 Omsk Slavic young men of 18-20 years of age without concomitant pathology was performed, supplemented by an X-ray examination of the head (to obtain teleroentgenograms in a lateral projection). The analysis of teleroentgenograms was carried out in the online service Mave Cloud.Results. According to the results of anthropometry, the longitudinal and transverse dimensions of the young men's heads, the zygomatic diameter and the full height of the face were assessed; the indicators of body growth, body weight, chest circumference and transverse chest diameter were determined. These indicators were used to calculate the indices. The value of the facial index was 81.86 (79.31; 88.88), the value of the head index was 76.65 (74.27; 79.47), the Rees-Eisenck index corresponded to 97.58 (94.62; 107.48), the Rohrer index was 13.34 (12.07; 15.48), the Pinier index was 11.1 (-10; 22), the Quetelet II index was 23.33 (22.03; 27.71). When analyzing teleroentgenograms, it was revealed that the values of some parameters in Omsk young men of 18-20 years of age differ from the values of the «norm». Thus, the indicators of the lower jaw length (Go-Gn), the ratio of the body of the lower jaw length to the length of the anterior base of the skull (Go-Me/S-N), the length of the posterior base of the skull (S-Ar), the height of the branch of the lower jaw (Ar-Go), the ratio of the heights of the face (S-Go/N-Me), the angle between the axis of the lower incisor and the plane of the lower jaw (IM IMPA) have greater values than the «norm»; and the figures of the angles sum according to Bjork (∠SUM Bjork), mandibular angle (∠Ar-Go-Me), maxillary angle (∠N-Go-Ar), upper jaw inclination angle (∠NSL-NL), lower jaw inclination angle (∠NSL-ML), intermaxillary angle (∠NL-ML), the angle between the lower jaw plane and the Frankfurt horizontal (∠FMA), have values less than the «norm». The values of the saddle angle (∠N-S-Ar) differed in young men with euryprosopic and leptoprosopic facial forms. The quantitative values of the lower jaw angle (ArGo-Me) and the upper jaw angle (N-Go-Ar) differed only in the representatives of the dolichocephalic and mesocephalic forms of the head.Conclusion. Quantitative values of cephalometric and somatometric parameters in Omsk young men of 18-20 years of age have distinctive features. Individual parameters of the maxillofacial area (according to teleroentgenograms) differ in persons with dolichocephalic and mesocephalic forms of the head and in the representatives of euryprosopic and leptoprosopic forms of the face.

Background: Literature specifically documenting clinical characteristics of childhood vitiligo are few when compared to the documentation in adults in Nigeria. This study aims to document the clinical characteristics of childhood vitiligo.Methods: This was a retrospective cross-sectional study of 35 children diagnosed to have vitiligo from January of 2005 to December of 2010 at the dermatology outpatient clinic of the University College Hospital, (UCH) Ibadan. A proforma was used to extract socio-demographic variables and clinical features from the chats. Ethical clearance for the study was given by the research and ethics committee of the hospital.Results: Over the 5 year period, 35 out of 264 children were diagnosed to have vitiligo giving an incidence of 13.3 %. The children were made up of 34.3% males and 65.7% females. At presentation, 71.4% of the children were aged 0-10 years. In 80% of the children, age at onset of vitiligo was before age 10 years especially at age 6-10 years. The commonest area of onset was the face/scalp (51.4%) and the commonest type of vitiligo was segmental. Severity of vitiligo was <9% in 97.1% of cases. Vitiligo was in an exposed part of the body in 88.6% of the children. Only females had the genitalia as area of onset of vitiligo.Conclusions: Childhood vitiligo is mainly segmental, re-pigments well and occurs more in females. Only females have the genital area as the area of onset.

The presence of catalase-positive rods (Fig. 1) of different dimensions, which frequently have a crystalline appearance by light microscopy, has been reported. They seem to be related to peroxisomes which were characterized morphologically and cytochemically in parotid and other exocrine glands of the rat by Hand in 1973. Our light microscopic studies of these spherical microbodies and rods of different sizes, stained by virtue of the peroxidatic activity of their catalase, indicate that they are almost entirely confined to the cells of the striated and execretory ducts of the submandibular gland in the mouse. The rods were usually noted only in the proximity of the ductal microbodies. The latter frequently showed a tendency to appear in linear close array, or even to be contiguous (Fig. 2). This suggested that the rods could be formed by the fusion of microbodies.

Pseudomonas aeruginosa is a widely represented species of bacteria possessing of a pathogenic potential. This infectious agent is causing wound infections, fibrotic cystitis, fibrosing pneumonia, bacterial sepsis, etc. The microorganism is highly resistant to antiseptics, disinfectants, immune system responses of the body. The responses of a quorum sense of this kind of bacteria ensure the inclusion of many pathogenicity factors. The analysis of the scientific literature made it possible to formulate four questions concerning the role of biofilms for the adaptation of P. aeruginosa to adverse environmental factors: Is another person appears to be predominantly of a source an etiological agent or the source of P. aeruginosa infection in the environment? Does the formation of biofilms influence on the antibiotic resistance? How the antagonistic activity of microorganisms is realized in biofilm form? What is the main function of biofilms in the functioning of bacteria? A hypothesis has been put forward the effect of biofilms on the increase of antibiotic resistance of bacteria and, in particular, P. aeruginosa to be secondary in charcter. It is more likely a biofilmboth to fulfill the function of storing nutrients and provide topical competition in the face of food scarcity. In connection with the incompatibility of the molecular radii of most antibiotics and pores in biofilm, biofilm is doubtful to be capable of performing a barrier function for protecting against antibiotics. However, with respect to antibodies and immunocompetent cells, the barrier function is beyond doubt. The biofilm is more likely to fulfill the function of storing nutrients and providing topical competition in conditions of scarcity of food resources.

The aim of this study is to demonstrate the use and the effectiveness of cephalometry and golden proportions analysis of the face in planning prosthetic treatments in totally edentulous patients. In order to apply this method, latero-lateral and posterior-anterior X-rays must be performed in addition to the common procedure. Two main concerns for totally edentulous patients are the establishment of the vertical dimension and the new position of the occlusal plane. The divine proportion analysis was carried out by the use of a golden divider. The prosthetic protocol was divided into three steps and a case was selected for better understanding. Referring to the golden relations, if the distance from the chin to the wing of the nose is 1.0, the distance from the nose to eye is 0.618. This proportion is useful and effective in determining the correct prosthetic vertical dimension. The incisal margin of the lower incisor must be positioned between Point A (A) and protuberance menti (Pm) according to the gold ratio 0.618 of the total height A-Pm. Posteriorly the occlusal plane must be placed 2 mm below the divine occlusal plane (traced from the incisal margin of lower incisors to Xi point). A prosthesis made in accordance with cephalometric parameters and divine proportions of the face helps to improve the patient’s aesthetics, function and social personality.

Abstract INTRODUCTION Controversy exists as to whether telephone clinics are appropriate in neurosurgical-oncology. The COVID-19 pandemic forced neuro-oncology services worldwide to re-design and at the University Hospitals Birmingham UK, telephone clinics were quickly implemented in select patients to limit numbers of patients attending hospital. It was important to determine how these changes were perceived by patients. METHODS A 20-question patient satisfaction questionnaire was distributed to patients who attended neuro-oncology clinic in person (“face-to-face”), or via the telephone. Fisher’s exact test was used to determine significance, which was set at p&lt; 0.05. RESULTS Eighty questionnaires were distributed between June 2020 and August 2020. Overall, 50% (n=40) of patients returned the questionnaire, 50% (n=23) of face-to-face and 50% (n=17) telephone patients. Of those who received telephone consultations, 88% (n=15) felt the consultation was convenient, 88% (n=15) were satisfied with their consultation and 18% (n=3) felt they would have preferred to have a face-to-face appointment. Of those who attended clinic in person, 96% (n=22) felt their consultation was convenient, 100% (n=23) were satisfied with their consultation and 13% (n=3) would have preferred a telephone consultation. Within the face-to-face clinic attendees, only 13% (n=3) were concerned regarding the COVID risk associated with attending hospital. There was no significant difference in patient convenience or satisfaction (p=0.565 and p=0.174 respectively) between face-to-face and telephone clinics. There was no significant difference in whether patients would’ve preferred the alternative method of consultation (p &gt; 0.999). CONCLUSION Our study suggests that careful patient selection for neuro-oncology telephone clinic is not inferior to face-to-face clinic. Telephone clinic during COVID-19 pandemic proved to be convenient, safe and effective. This global health crisis has transformed telephone neuro-oncology consultations from an experimental innovation into established practice and should be continued beyond the pandemic in select cases.

The analysis of motivational systems underlying temporal organisation in animal behaviour has relied primarily on two conceptual functional frameworks: Homeostasis and biological clocks. Homeostasis is one of the most general and influential concepts in physiology. Walter Cannon introduced homeostasis as a universal regulatory principle which animals employ to maintain constancy of their ‘internal milieu’ in the face of challenges and perturbations from the external environment. Cannon spoke of “The Wisdom of the Body”, the collective of responses designed to defend the ideal internal state against those perturbations.

AbstractAn altered facial appearance is more difficult to face, than problems related to ill-fitting denture or eating. The selection of maxillary anterior teeth for complete denture has long posed problem in clinical practice and a controversy about the best method to employ still exists. An attempt is made in the present study to clinically correlate the face form with maxillary central incisor tooth form in males and females of Davangere population. In 1914, Leon William's projected the “the form method” where he classified facial forms as square, tapering, and ovoid. Maxillary central incisors were selected according to the facial forms.Of total 100 subjects four different tooth forms and face forms were evaluated. They are: square, ovoid, square-tapered, tapered. No significant correlation existed between face form in male and females. Females exhibited greater correlation between face forms and inverted tooth form but that correlation is not sufficient to serve as a guide for selection of anterior teeth.
