Ryle’S Tube

Dear sir, Nasogastric tube (Ryle’s tube) insertion is one of the commonest ward procedures done for different indications. During selected surgical procedures, the insertion of such tubes is done in the preoperative ward. There are lot of reported difficulties during insertion in the intraoperative period.1 The Ryle’s tube is inserted in the classical manner but usually adjusted to enable the surgeon to do the gut surgery. The tube is usually fixed to the nose by a plaster wound round the tube. This technique is usually difficult to unwound if there is a need to reposition. In surgical and medical wards, the necessity for repositioning is not very significant. But during the intraoperative period, the surgeons always prefer to move the tube here and there to make the operative field better. This in turn causes much discomfort to the attending anaesthesiologist if the plaster is stuck in a traditional way.  Hence, we propose a novel technique of fixation wherein we get the advantages of avoiding accidental removal but with the ease of frequent positional adjustment. A sixty-five-year-old male came for upper Gastro-intestinal surgery. The Ryle’s tube was inserted in the ward and fixed as given in fig 1. To adjust the position after removal of the plaster becomes a herculean task. Its more difficult to adjust the plaster with gloved hands. The plaster was removed before induction and fixed as described below. The first plaster (P1 in fig 2) was vertical and fixed the tube to the nose in a vertical fashion. The portion of the plaster which sticks to the tube should be around 50 % of the plaster length. Usually there is a small gap between the attachment of the tube and the nose. The next or the second plaster (P2 in fig 2) was transverse which fixed the vertical plaster to the nose. The transverse plaster never touched the Ryle’s tube. (Fig 2) If we need to adjust the position, the plasters can be easily loosened to adjust and fix again. The portion of the plaster in the gap can be lifted to loosen. There is no need for changing the plasters. Many a time, the surgeons may ask for repeated changes of position during the surgery. Hence this Partha’s technique of fixation suits repeated unfastening and regluing. There are reports of lost Ryle’s tubes2 after fixation in the wards. Lorente3 in his study of intensive care patients, found an incidence of accidental removal of Ryle’s tube as 4.48%. A single plaster use may be a cause of malposition. An extensive search of the literature did not reveal fixation techniques with their pros and cons. We have been using this technique for many years so far with minimal problems.  This report is limited to the fact that it is not used much with no comparative studies to know its advantages and disadvantages.

Several imaging methodologies have been used in biofilm studies, contributing to deepening the knowledge on their structure. This review illustrates the most widely used microscopy techniques in biofilm investigations, focusing on traditional and innovative scanning electron microscopy techniques such as scanning electron microscopy (SEM), variable pressure SEM (VP-SEM), environmental SEM (ESEM), and the more recent ambiental SEM (ASEM), ending with the cutting edge Cryo-SEM and focused ion beam SEM (FIB SEM), highlighting the pros and cons of several methods with particular emphasis on conventional SEM and VP-SEM. As each technique has its own advantages and disadvantages, the choice of the most appropriate method must be done carefully, based on the specific aim of the study. The evaluation of the drug effects on biofilm requires imaging methods that show the most detailed ultrastructural features of the biofilm. In this kind of research, the use of scanning electron microscopy with customized protocols such as osmium tetroxide (OsO4), ruthenium red (RR), tannic acid (TA) staining, and ionic liquid (IL) treatment is unrivalled for its image quality, magnification, resolution, minimal sample loss, and actual sample structure preservation. The combined use of innovative SEM protocols and 3-D image analysis software will allow for quantitative data from SEM images to be extracted; in this way, data from images of samples that have undergone different antibiofilm treatments can be compared.

Information technology has created tremendous chances in higher education across the globe. With the availability and flexibility of learning online, there are increasing competitions between online learning and traditional, face-to-face classroom. These two types of learning both have their pros and cons. From the advantages and disadvantages of online learning, universities have recently changed the way of their teaching through combining online learning and traditional classroom. Therefore, it is necessary to investigate and understand the advancements of the combination of the two types of learning. In this paper, we will introduce the advantages and disadvantages of online learning and the combined learning. We also share our experience on teaching at Flinders University, South Australia through Flinders learning online system. From this knowledge, we will suggest some solutions about building a combined learning system which is suitable for Vietnamese universities.

There are many pros and cons with the protocols used to diagnose patient with TB, particularly because research isn't able to correlate findings with the virulence of the tuberculosis pathogen. This has resulted in further experiments to try optimise protocols for better evaluation of susceptible and resistant tuberculosis strains. This indicates the need for more health-care facilities to treat patients with tuberculosis, or co-tuberculosis infections, more precisely. This article presents some advantages and disadvantages of tuberculosis treatment protocols, with emphasis on drugs, tuberculosis data sets and the administration of plant compounds. This paper also highlights some points on the mechanism of drug action with tuberculosis. Controversies and the present status of tuberculosis studies are also commented on. This is the first (generalised) paper to highlight laboratory as well as non-laboratory points pertaining to tuberculosis and tuberculosis protocols.

The sliding genioplasty for cosmetic augmentation of microgenia is a common procedure performed by maxillofacial and cosmetic surgeons. There are multiple designs for this osteotomy, and multiple fixation techniques proposed, among which include wires, screws, bone plates, and pins. Likewise, there are many advantages and disadvantages to each of the designs and the fixation techniques that will be utilized according to the surgical indications and the surgeon's preference. A techique used at the Medical College of Wisconsin in Milwaukee involves fixation of the osteotomy segments with Kirschner pins placed at multiple divergent angles. This technique allows for placement of the free segments in virtually any location, and provides for a type of rigid stabilization, particularly in large anterior and vertical movements. One criticism that has been suggested with the use of Kirschner pins is the possibility of migration. This retrospective study evaluates 13 patients who underwent augmentation genioplasty, rigidly fixated with Kirschner pins. Twenty-eight total Kirschner pins were placed, with one being removed. The mean postoperative follow-up was 32 months, and the average number of pins placed was 2.15 per patient. It would appear then, from this study, that migration of Kirschner pins when used with the sliding genioplasty, is not a significant postoperative concern.

Orbital Defects

AbstractOrbital and craniomaxillofacial defects, in general, are best approached preoperatively by a multidisciplinary team with a clear reconstructive plan in place. Orbital defects result from a myriad of underlying diseases and injuries, and reconstruction after orbital evisceration, enucleation, or exenteration can pose a challenge to the reconstructive team. Reconstruction of orbital injuries with orbital implants and prostheses can lead to acceptable aesthetic outcomes, and the reconstructive surgeon should be familiar with current orbital implants and prostheses. Herein, the authors review terminology and classifications of orbital defects, different types of orbital implants, advantages and disadvantages of different orbital implant reconstructive options, types of orbital prostheses, and pros and cons of different prosthetic options.

The authors present a novel technique of atlantoaxial fixation using multiaxial C-1 posterior arch screws. The technique involves the insertion of bilateral multiaxial C-1 posterior arch screws, which are connected by crosslinked rods to bilateral multiaxial C-2 pars screws. The clinical results are presented in 3 patients in whom anomalies of the vertebral arteries, C-1 lateral masses, and/or posterior arch of C-1 presented difficulty using existing fixation techniques with transarticular screws, C-1 lateral mass screws, or posterior wiring. The C-1 posterior arch screws achieved solid fixation and their insertion appeared to be technically less demanding than that of transarticular or C-1 lateral mass screws. This technique may reduce the risk of complications compared with existing techniques, especially in patients with anatomical variants of the vertebral artery, C-1 lateral masses, or C-1 posterior arch. This technique may prove to be an attractive fixation option in patients with normal anatomy.

The article aims to present the benefits and costs for the SADC member countries of the conclusion of EPA and of the implementation of trade liberalisation thereunder, in the light of their trade relations with the European Union. The hypothesis adopted is that for the majority of the SADC countries entering into the agreement will involve improved access for their products to the EU market. The assessment of the advantages and disadvantages of the conclusion of an EPA will take account of a situation in which the countries of the region would not sign an EPA: how their customs status would change and whether it would affect the conditions of trade with the European Union.

Application of external fixators (EF) in pelvic fractures is one of the important components of antishock therapy in patients with polytrauma. However various fixation techniques possess certain advantages and disadvantages. Comparative analysis of 4 most commonly used variants of pelvic EF mounting, i.e. classic - via upper flaring portion of the ilium, supra-acetabular, orthogonal - combination of screws passes through the wings and supra-acetabular region, and subcristal, that were applied in 32, 48, 13 and 3 patients, was performed. Results of the analysis showed that supra-acetabular pelvic fixation technique a preferable one due to its high efficacy and lower rate of complications as compared to other external fixation methods.

Recently it has become obvious that accumulation of knowledge itself has lost its value, that is why the task of development of the necessity and ability of a person not only to get and renew the knowledge by himself but also accomplish this process throughout his life has reached the first place. The effectiveness of distant learning lies in the fact that students can work with the material how they want and when they can. At the same time the disadvantages of distant learning reveal in the absence of contact work between a teacher and a student, which means lack of pedagogical influence, lack of the development of motivation and self-discipline among students that are vital in the process of distant learning. Furthermore, it is necessary to highlight that not all disciplines can be taught in the form of distant learning. The article shows the results of a sociological survey of teachers and students about the advantages and disadvantages of distant learning in the isolation mode. The aims of the survey are to study the attitude of a teacher and a student to the distant learning, to point out pros and cons of the distant learning and to reveal possible difficulties and problems in the work of a teacher and a student. The comparative analysis with the studies of previous years is being given.

Introduction: Family planning importance is increasing progressively and is regarded as an essential part in every couple’s life. Family planning has a lot of benefits for the whole family as it provides a better control over the period between each pregnancy leading to a better balance over the personal, financial, and societal life. There are multiple birth control methods, from which couples can choose from with the assistance of their physicians since each method has its own advantages and disadvantages. Furthermore, some contraceptive methods may be more suited for a certain couple or situation than another one. This review of current methods aims to shed the lights on the various contraception options along with their advantages and disadvantages to aid providers in taking care of their patients. Methodology: A thorough search was carried out on PubMed using the most suitable keywords representing the aim of the present study. A total of 120 were found and based on whether they are suited to achieve the aim of the study, 28 were selected. Discussion: There is a great variety of birth control methods, and each has its associated advantages and disadvantages. Barrier contraceptive methods, most common of which are male condoms, are extremely popular in Western countries. Combined hormonal contraception methods which are available in the form of pills, patches, and rings. Progestin only contraception either in the form of a pill, injection or an implant is the most commonly used type among breastfeeding women. Furthermore, intrauterine devices are another effective contraceptive method which may be copper-based or hormonal-based. Conclusion: Contraception is an integral part of family planning, which can be achieved through a variety of methods. Each birth control method has its own pros and cons that should be explained to the couple clearly, so they can choose the method that is most suited for them.
