K e y w o r d s Among various pathogenic species of fungi, Candida is the most prominent cause of fungal infections. Due to non-specific clinical presentation, candidiasis; diagnosis of disseminated candidiasis is difficult as compared to mucocutaneous polymerase candidiasis. Prompt and accurate identification of Candida species is very essential chain reaction. Conventional methods for the diagnosis of candidiasis are less sensitive and time consuming, hence, immunodiagnostic and molecular techniques can be recommended for early and specific diagnosis. Introduction Fungi, once considered non-pathogenic Although a part of normal microbiota, microbiological curiosities have emerged Candida is capable of causing various as an important cause of community clinical manifestations ranging from acquired and health care associated mucocutaneous overgrowth to infections (Chakrabarti et al. Only a few broad spectrum antibiotics and decades back, the role of Candida in immunosuppressive drugs increase the establishment and progression of infection vulnerability to fungal infections was considered to be passive, and organic (Deorukhkar et al. Among weakness or an immunocompromised various pathogenic species of fungi, status of the host was considered as the Candida is the most prominent cause of vital mechanism responsible for fungal infections (Sullivan et al. Sci (2014) 3(1): 206-218 candidiasis was called the disease of microbiological services for prediction of diseased. Recently this concept has likely drug susceptibility and to guide changed and it is established that Candida treatment. In the present study, the can actively participate in the literature on conventional and molecular pathophysiology of the disease techniques for diagnosis of candidiasis is progression by using mechanisms of reviewed. Laboratory diagnosis of candidiasis Virulence factors like tissue adhesion, Like for any other infections, the phenotypic switching, biofilm formation laboratory diagnosis of candidiasis and production of extracellular hydrolytic depends on the infection caused by it. As enzymes play an important role in discussed earlier Candida is capable of colonization and invasion of host tissues causing a wide range of clinical (Sachin et al. Figure 1 summarizes Saini, 2013a; Deorukhkar and Saini, various clinical manifestations of Candida 2013b). This review is focused on the laboratory diagnosis of mucocutaneous the genus Candida is composed of and disseminated candidiasis. The change in the trends of Direct examination candidiasis can be attributed to various factors like severe immunosuppression or the direct examination of clinical illness, prematurity, exposure to broad specimens is done by wet mount spectrum antibiotics and empirical use of preparation. Sci (2014) 3(1): 206-218 preparation before microscopic demonstration of pseudohyphae along examination. Addition of Parker s ink or with yeast cells (Figure 2) is an important the lacto phenol cotton blue also benefit diagnostic feature to distinguish infection the demonstration of fungal elements from normal colonization (Segal and Elad, (Segal and Elad, 2005). It binds to chitin Direct microscopic examination is a cost and cellulose in fungal cell wall and effective, rapid method for diagnosis of fluoresces on excitation by long wave candidiasis. It permits the growth of Candida demonstrated by wet mount preparation and suppresses the growth of many but not and can be used as an indication of all bacteria due to its low pH. The fixed Antibiotics prevent the growth of bacteria, smear can be stained by Gram staining, whereas cycloheximide avoids Giemsa or methylene blue. Species identification the culture medium can be incubated at 0 0 28 C or/and at 37 C. Candida colonies Speciation of Candida is done on the basis appear on medium within 24 to 72 hours. Varieties of In diagnostic mycology the basic work up differential media are available for for yeast identification starts with germ speciation of Candida. Germ tube formation was first Pagano-Levin agar (Figure 4), reported by Reynolds and Braude and phosphomolybdate agar, Nickerson s hence the germ tube test is also known as medium (Costa et al. These media contains chromogenic substrates that react with enzymes secreted Due to the time required to prepare human by yeast cells, resulting in various serum and inherent safety problems pigmentations. These enzymes are species concerned with its use, many clinical specific and allow species identification on microbiological laboratories have started the basis of colony color and using non-human serum media for testing characteristics (Horvath et al. Trypticase soya broth is differentiation medium for clinical found to be more stable, effective and safe specimens likely to contain yeasts. It also than other media for production of germ acts as differential medium for tube (Deorukhkar et al. In this test the observer must be able to Although chromogenic media are more differentiate between germ tube and 209 Int. A criterion for germ tube positivity is Fermentation tests are used to supplement observation of minimum five germ tube in carbohydrate assimilation test results. Negative these tests are more difficult to perform results are confirmed by examining at least and are prone to variation (Segal and Elad, 10 high power fields for the presence of 2005). Other conventional methods for Species of Candida can be characterized speciation of Candida. For this purpose ability to ferment a given carbohydrate nutritionally deficient media like corn also assimilate it, but not necessarily vice meal tween-80 agar, rice starch agar and versa (Segal and Elad, 2005). These nutritionally deficient media suppress the the biochemical identification of Candida vegetative growth and promote spp. The classical assimilation test developed by Urease test can be used for identification Wickerham and Burton was further of C. Though these commercial systems identification is not a standard routine are costly they have several advantages procedure for laboratory diagnosis of like rapid identification, require no or less candidiasis. Sci (2014) 3(1): 206-218 Molecular diagnosis though possible, is specimens blood culture is easy to obtain. These include the development of Disseminated Candidiasis lysis-centrifugation tubes and automated monitoring of blood culture bottles. The As compared to superficial and lysis centrifugation system increases the mucocutaneous candidiasis the clinical yield of Candida spp. This method institution of appropriate antifungal reduces the time between inoculation and treatment (Ellepola and Morrison, 2005; detection of growth. In blood culturing systems with continuous most cases, invasive procedures are growth monitoring. Sci (2014) 3(1): 206-218 In case of urine samples, colony counts are (Ahmad and Khan, 2012). The sensitivity important to differentiate between and specificity of anti-mannan antibody colonization or contamination and test when used alone was reported to be infection. Mannan is a major cell wall component of Candida and it accounts for upto 7% of Antibody detection total dry weight of cell and is released in blood circulation during infection (Ahmad the clinical utility of antibody detection and Khan, 2012). False negative results in antibody complexes is very necessary for immunocompromised patients, where detection of mannan in the serum since there is low or undetectable levels of these immune complexes masks antigenic antibodies. Mannan Currently two tests are available for can be detected in serum and other body antibody detection. The overall is a structural component of Candida cell sensitivity and specificity of this test is wall (Odabasi et al. Its presence in reported to be 58% and 93% respectively the circulation of patients signifies (Ahmed and Khan, 2012). As mannan is systemic mycoses (Ellepola and Morrison, rapidly cleared from the circulation, this 2005). Although this test is incapable can be used for detecting Candida spp of identification of causative fungus, its directly from clinical specimens (Sullivan rapidity makes it an attractive screening et al. The time required for culture and the incidence of Candida infections has speciation of Candida isolates necessitate increased over the past few decades. The conventional are a common cause of health care methods of culture and identification of associated infection with significant Candida requires a minimum of one week. On the other hand, molecular diagnostic Candida albicans is the most common techniques are rapid, sensitive and specific species implicated in infections, but in (Sullivan et al.

The clinical use of antibacterial drugs, immunosuppressive agents afer organ transplantation, cancer chemotherapy, and advances in surgery are associated with increasing risk of fungal infections. Opportunistic pathogens from the genera Candida and Aspergillus as well as pathogenic fungi from the genus Cryptococcus can invade human organism and may lead to mucosal and skin in fections or to deep-seated mycoses of almost all inner organs, especially in immunocompromised patients. Nowadays, there are some efective antifungal agents, but, unfortunately, some of the pathogenic species show increasing resistance. The identifcation of fungal virulence factors and recognition of mechanisms of pathogenesis may lead to development of new efcient antifungal therapies. This review is focused on major virulence factors of the most common fungal patho gens of humans: Candida albicans, Aspergillus fumigatus and Cryptococcus neoformans. The ad herence to host cells and tissues, secretion of hydrolytic enzymes, phenotypic switching and mor phological dimorphism contribute to C. The ability to grow at 37?C, capsule synthesis and melanin formation are important virulence factors of C.

Rim101 is a zinc finger-containing transcription factor that is inactive under acidic conditions but activated at neutral to alkaline conditions and alters gene expression 42 hair loss mayo clinic discount 0.5 mg dutas fast delivery, 43 hair loss cure 5 years order dutas overnight delivery, Hypha development can also be stimulated by hypoxia and by embedding C hair loss uae trusted dutas 0.5mg. These inputs activate morphogenesis through additional alternative pathways that involve the transcription factors Efg1 and Efh1 during hypoxia-induced hypha formation and the morphogenetic regulator Czf1 during matrix induced hypha formation (Figure 3B) 44 hair loss in men 70s buy dutas online, 45 hair loss in men questions dutas 0.5mg mastercard. Genotoxic stresses that disturb cell cycle progression can stimulate filamentous growth in C hair loss cure india buy 0.5 mg dutas visa. Reactive oxygen species generated by phagocytic cells also induce genotoxic stress. For example, hydrogen peroxide activates hyphal development through Rad53 signalling 49. This will influence the correspondingly complex network of immune detection mechanisms and responses. It is interesting to note that the presence of pseudohyphae has yet to be considered in terms of their relevance to pathogenesis and the immune response. Morphogenesis and pathogen recognition How the immune system interacts with the various morphogenetic forms of fungi is relatively poorly understood. Many excellent reviews have been published on this subject 10, 11, 52, and therefore we will only briefly summarize the most important aspects (Figure 4). Immune responses can be stimulated not only by components from the outer layer of the cell wall but also by components from the inner Nat Rev Microbiol. Page 5 layer, as these can be exposed at the cell surface at bud scars or by the action of antifungal drugs and host enzymes 53. Dectin-2 is mainly present on myeloid cells and maturing inflammatory monocytes 76. Nlrp3-deficient and apoptosis-associated speck-like protein containing a caspase recruitment domain (Asc)-deficient mice are more susceptible to both systemic 91-93 and mucosal 94 C. Differential recognition of yeast and hyphae Although much progress has been made on the recognition of C. In addition, differential recognition of mannans from hyphae and yeasts by dectin-2 has been proposed 99, although the differences in mannan structure that are responsible for these effects are unclear 20, 100. Discriminating mucosal colonization and tissue invasion the capacity to undergo a reversible yeast-hypha transformation is linked to the virulence of C. The host must keep the fungal burden below this threshold and distinguish non-pathogenic C. Sensing invasion by epithelial cells Mucosal epithelial cells not only provide a physical barrier but can also recognize fungi and respond by producing cytokines105, 106. The relatively small number of yeast cells present does not induce epithelial cell damage, and thus does not trigger a cytokine response in epithelial cells or in mucosal macrophages. This view is supported by the observation that the efg1/efg1 mutant, which is not able to form hyphae, is much less capable of inducing endocytosis than wild-type cells 110. Hyphae might thus have molecules on their cell wall that can bind to epithelial cell receptors leading to the induction of endocytosis. Furthermore, H heterozygous carriers of an early-stop-codon mutation (Tyr238X) in the? A live challenge model in humans revealed that symptomatic infection correlated with a neutrophil infiltrate in the vaginal lumen and elevated fungal burden. Furthermore, the neutrophil chemotactic factors S100A8 and S100A9 can be produced by vaginal epithelial cells following interaction with C. Nevertheless, the question remains why are these mechanisms induced by invading, but not by colonizing, fungi? These observations allow us to propose a model to explain the mechanism by which tissue antigen-presenting cells discriminate between C. It should be noted however that there is low-grade activation of the cellular immune response during colonization, as suggested by the presence of memory T 17 responses in healthy individuals75. Conclusions and future perspectives Much has recently been learned about the mechanisms through which the immune system discriminates between C. These discoveries not only have important consequences for our understanding of the immune response to fungi, but they also open new avenues for future research. Moreover, several crucial questions related to mucosal antifungal immunity remain unanswered. For example, what are the differences between the host immune responses at the oral mucosa and the vaginal mucosa? The gastrointestinal tract of mammals is inhabited by hundreds of distinct species of commensal microorganisms that exist in a mutualistic relationship with the host. The commensal microbiota throughout the whole gastrointestinal tract might protect the body against invading mucosal pathogens, but when the mechanisms that control the growth of these commensals are disturbed we might pay a high price: autoimmunity.

Best marker For studies reporting on tumor markers with a sensitivity of more than 60% a separate overview is shown in Table 3. However, its sensitivity was increased when individual cut-of values were applied, based on the lowest postoperative value corrected for inter-assay variation [23]. Points of discussion In all patients included in our review postoperative serial measurements were performed, independent of the preoperative marker level (which was in some studies not measured at all). Tese studies strengthen our conviction that serial measurements of other markers of interest are also useful when the preoperative value is not known [36,37]. The currently emerging class of molecular tumor markers includes circulating nucleic acids, epigenetic alterations, gene-expression profles and analysis of circulating cancer cells. We realize that by excluding histologically estimated markers and qualitative markers, most of these new tumor markers have not been included in this review. How 159 Tumor markers in fnding recurrent disease in colorectal cancer: a diagnostic review ever, by applying strict inclusion criteria we avoided creating a selection bias and thus comparability of studies is more reliable. Furthermore the use of serum measurements in daily practice is common and easy in comparison to the use of histological markers. Tumor marker panels are relatively new and promising in follow-up of colorectal cancer. Additive value on indicating recurrence is ofen found, suggesting panels could outperform routine imaging techniques in follow-up, with favorable fnancial perspec tive. Recent evaluation of an extensive tumor marker panel demonstrated an increase in sensitivity in fnding recurrences [32]. In the current review, the additional value of tumor marker panels has also been shown. Specifcity of tumor markers is the number of patients without recurrence who are correctly identifed by the tumor marker as not having a recurrence. It is known that some tumor markers not only increase in case of recurrent disease, but also in several non malignant processes such as infection and smoking [38]. Limitations Diferences in study designs regarding patient and tumor stage selection and follow-up schedules infuences our conclusions. The authors recognize that the comparison of diferent designs is the main weakness of our study. However, criteria for patient selec tion and follow-up schedules have not yet been standardized. We tried to overcome this bias issue by applying strict study selection using standardized study criteria and two independent reviewers. We excluded studies with quality scores that were too low according to these guidelines. Furthermore, it is important to realize that only serially and quantita tively measured follow-up markers were considered in this review. Since nucleic acid markers are qualitative markers, most of these were excluded; they either are present or absent. Terefore, the diagnostic accuracy of the marker depends on the cut-of level applied. A variety of markers 160 measured with several assays were included; cut-of values difered per study, therefore resulting in bias. In the one study that did not, various cut-of values were tested to obtain the value with the highest sensitivity. Immunoassays are known to have high analytical sensitivity, which means low concentrations can be measured reliably. Other strengths of immunoassays are the potential of full automation and its practicability, with rela tive little technical expertise required. The main problem in comparing immunoassay results, however, is the fact that results obtained from each commercial available assay depend on their own antibody with its specifc characteristics. This leads to diferent cut-of values and reference values for the one marker and complicates inter-laboratory comparability. Also the inter and intra-assay variability of the commercially obtained assays cause difculties for patient follow-up studies [39]. Advantages of the Biobank would be the uniform strategy in which all sera are analyzed with the same assay, and that all patients undergo the same study regimen and design.

Colorectal cancer follow-up is challenging for medical professionals in many ways. Improvements in preoperative staging, namely routinely using better imaging techniques, have led to a diferent pattern of recurrences. Patients expect that the doctor recognizes recurrent disease in an early phase; doctors have to know the right steps to take if any suspicion arises. With ameliorating surgical and ablative techniques for detected recurrences, more is possible; but on the other hand the popula tion grows older and older so that certain options are barred. Medical research is based on rational comings and goings, however oncological care always comes with emotions. Since follow-up has many aspects, such as imaging and blood measurements, there is a risk of non-com parability between diferent studies with diferent follow-up methods; therefore a specifc focus has to be made. Curative treatment options for recurrent disease have been improved considerably in the last decade. Of 28 patients with recurrent disease, 12 patients (43%) were eligible for curative treatment. To this end, a sofware program was developed to help doctors with large groups of patients in follow-up undergoing frequent laboratory measurements. Results show that the sofware is safe for the patients oncological care as well as convenient for medical specialists. In a prospective randomized-controlled trial, a new follow-up protocol was rolled out in eleven Dutch hospitals, aiming to detect recurrent disease earlier than the usual follow-up care (the current Dutch guideline). Although 5-year survival have to be awaited, the results show that the new protocol is better in the detection of recurrent disease than the use of the Dutch guideline during the study period. In Chapter 7, the incremental cost-efectiveness ratios for recurrences are calculated. To detect one percent more recurrences in the intervention protocol com pared to the control protocol, an additional amount of ?94 is paid and in order to detect one percent additional curable recurrences, an extra amount of 607 is spent for the intensifed follow-up compared to standard follow-up. Considering the expected costs for palliative treatment (mostly chemotherapy) in case of non-curable recurrences, the associated costs are fairly acceptable. In Chapter 8 the psychological efects of the intensi fed follow-up are described. The intensifed follow-up protocol posed no adverse efects on patients attitude towards the follow-up and psychological functioning. In general, patients were more nervous and anxious at the start of the new follow-up protocol and had high expectations of it. Terefore a prospective study of these markers is deemed necessary to investigate their real value, and to overcome design and inclusion biases. Future Perspectives The evidence that more recurrences are treated with curative intent (Chapter 5) is not suf fcient. Signifcantly higher rates of curable recurrences were detected in the intensifed follow-up schedules compared to minimum follow-up (respectively 6. However the real clini cal relevance of better follow-up strategies lies in survival gain and the most important next step on this topic is thus to study the efects of the new follow-up regimen on both disease-specifc and overall survival. And if these statistically diferences are found, the discussion should be focused on the clinical relevance of the diferences. The stepped wedge design could also contribute to a lack of power of survival analyses. It is an elegant, but complex design and it has to be taken in mind that all patients are exposed to the intensifed follow-up regimen later in time than to the control protocol. In the perspective of improving colorectal cancer survival, the role for the type and location of recurrences on the fnal outcome have to become clearer. Detailed in vestigation of the detected recurrences will be useful, since detected recurrences do not all have the same chances on curative treatment. The treatment possibilities and defnite outcomes were debated and defned per recurrence, however the details of the exact way in which recurrences were detected and the given treatments per recurrence have to be further specifed and investigated. Diferences in approach per hospital can be studied, and both the curative treatments (surgical resection, ablative techniques for hepatic 174 Chapter 10 metastases, stereotactic radiotherapy for pulmonary lesions, of which the defnition of curability itself is questionable) and the palliative options (chemotherapeutic regimens, strictly supportive care, wait and see policy) have to be more specifed. In Chapter 6 the follow-up regimen has been studied on diagnostic accuracy, but with the current sensitivity of 5 5% for signalling re current disease, this is not optimal yet. Data on the clinical course per patient continues to be collected for the whole study group and thus can be put into the model. In this way we can work in the direction of patient-tailored, optimized follow-up. Per hospital, a medical professional such as a nurse practitioner can be in charge of all patients in follow-up. This person has more time for patients than the medical specialist, a rea son why he or she could also have time to help patient with coping of their disease. The concept of a nurse practitioner is, of course, not new and has already been introduced in several hospitals, for example for breast cancer care. He or she can support follow-up more and better if modern 175 Summary and Future Perspectives media in daily practice are put in. At his/her turn this nurse practitioner can feed back the information to the patient through the app. Using the app, each patient is the owner of his medical data and he could be more involved in decision making, enlarging patient empowerment. In this way, an old and almost old-fashioned tumor marker can efciently revive in current times. De behandeling is gericht op operatieve verwijdering van de kwaadaardigheid zodat er geen kanker meer aanwezig is; dit wordt curatie genoemd. Na curatieve chirurgie voor colorectale kanker blijven patienten onder controle bij de arts. Het belangrijkste doel van de follow-up is de vroegtijdige opsporing van terugkerende (recidiverende) ziekte; dit kan gaan om zowel locaal recidief (in de darm) of uitzaaiingen elders in het lichaam. Verbeteringen in de detectie van de uitgebreidheid van de ziekte voor de operatie (de preoperatieve stadiering) hebben geleid tot een ander patroon in de diagnose van reci dieven na de operatie. Patienten verwachten dat de dokter recidief ziekte in een vroeg stadium herkent; artsen moeten de juiste stappen weten the zetten indien een vermoeden op recidief ziekte ontstaat. Enerzijds heef het verbeteren van chirurgische technieken geleid tot meer mogelijkheden voor het behandelen van recidieven; anderzijds vergrijst de patientenpopulatie zodat sommige opties een brug the ver zijn voor de oudere patient. Het medisch handelen wordt gebaseerd op rationele, liefst bewezen methoden, maar juist bij oncologische zorg spelen emoties en minder rationele argumenten vaak een rol in de medische besluitvorming. Follow-up bestaat uit meerdere onderdelen zoals beeldvormend onderzoek en bloedonderzoek. Bij het doen van wetenschappelijk onderzoek moet de focus worden gelegd op specifeke aspecten van follow-up om het aandeel van elk aspect in de uitkomst (zoals het eerder vinden van een recidief) apart the kunnen onderzoeken. Recidieven werden gevonden in 28 patienten (12%, gemiddelde follow-up peri ode van 18 maanden). Van deze 28 patienten kwamen er 12 (43%) in aanmerking voor een curatieve behandeling. Daarnaast kwam aan het licht dat de logistiek voor de frequente laboratoriumtests complex is; om hierin tegemoet the komen werd een ondersteunend sofwareprogramma ontwikkeld. Deze patientengroep werd vergeleken met een groep die de gebruikelijke follow-up onderging, zonder ondersteu ning van het sofwareprogramma. De resultaten laten zien dat de sofware veilig is wat betref oncologische zorg; daarbij wordt het sofware programma positief gewaardeerd door de artsen die ermee werken. De werkhypothese was dat recidieven eerder zouden worden opgespoord in dat protocol in vergelijking met de gebruikelijke follow-up (de huidige Nederlandse richtlijn) en dat die recidieven daardoor vaker curatief the behandelen waren. Hoewel de 5-jaars en 10-jaars overleving moeten worden afgewacht, laten de resulta ten dus zien dat het nieuwe protocol beter is in het opsporen van terugkerende ziekte dan de huidige Nederlandse richtlijn. Het voorgestelde schema van 20% stijging per twee maanden, gevolgd door een verdere stijging vier weken later had een sensitiviteit van 55% en een specifciteit van 92% met betrekking tot de detectie van recidieven en is dus geschikt als een scree nende follow-up ?tool. Wanneer een nieuwe behandeling, in dit geval een nieuwe manier van follow-up, aangetoond efectiever is dan de tot dan toe heersende methode, moet de balans tus sen het extra efect en de geassocieerde kosten worden opgemaakt om een beslissing the kunnen nemen over de implementatie van het nieuwe protocol. De kosten voor het detecteren van 1 procent meer recidieven in de het nieuwe protocol vergeleken met het controle-protocol bedragen 94. De kosten voor de detectie van een procent extra curabele recidieven bedragen 607. In het licht van de the verwachten kosten van een palliatieve behandeling (meestal chemotherapie) bij incurabele recidieven worden deze bedragen als acceptabel beschouwd; het nieuwe protocol is kosten-efectief. In hoofdstuk 8 zijn de psychologische efecten van de geintensiveerde follow-up beschreven. Dit werd onderzocht met vragenlijsten, die alle patienten tweemaal kregen opgestuurd. Het nieuwe follow-up protocol heef geen nadelige efecten op de houding van de patient ten aanzien van follow-up, noch op het psychisch functioneren van de patient.

It is most common in children, extends over many years and may finally result in the loss of the lashes, with the edge of the lid, thickened, reddened and turned out. Fit glasses if there is eye strain, reform the mode of life and attend to any constitutional disease that may tend to make it worse. The edges of the lids should be washed carefully with soap and warm water or mild solution of borax or soda until the crusts are all cleaned off and then use at night an ointment composed of the following ingredients: Yellow oxide of Mercury 2-1/2 grains Petrolatum 2-1/2 drams Mix and make an ointment and rub on the edge of the lids every night, first cleaning them. When it does not reach the pus stage, it often leaves a hard swelling (blind stye). As ill health may be the cause, a tonic may be needed; glasses properly fitted should be worn and a boric acid eyewash used until long after the stye has disappeared. Ill health produces a poor circulation of the blood and a good tonic will be found beneficial. The conjunctiva on the cornea is reddened and that on the lid is thickened, reddened and rough. The sight is slightly affected by the discharge on the cornea, which is otherwise clear. The first stage lasts a few hours or a day and then the discharge follows which may last a few days or a week or more. A wash of hot water can be used to cleanse the eye or ten to sixty grains (one teaspoonful) of boric acid to an ounce of water can be used as a wash also. The following remedies are good in combination as follows: Alum 3 grains Sulphate of Zinc 2 grains Distilled Water 1 ounce Mix and drop one drop into the eye two or three times daily. Soon the discharge appears and shortly becomes creamy pus, which runs from the eyes when the swollen lids are partly opened. As the disease continues to advance, the membrane of the lid is thickened, red and velvety looking and the conjunctiva (membrane) in the eye is swollen, puffy and watery. If the pus is not cleaned from the eye, the cornea may look dim and ulcers may appear. If the ulcer eats through the cornea the iris is apt to be caught in the opening and in the scar resulting from the ulcer. The cornea may later bulge and protrude or the disease may involve the whole eye in an inflammation which may destroy it. It causes a great many cases of blindness and generally the cases are neglected too long. At the first both the eyes should be bathed and the same piece of linen should not be used for both eyes. As soon as any redness appears the eye should be frequently bathed with this warm, weak solution of boric acid and sometimes cold compresses should be used by taking squares of folded gauze or masses of absorbent cotton. Take them cold from a block of ice and lay them over the eyes, and keep constantly changing to keep them cold. This relieves the congestion and prevents a great amount of blood from flowing and settling (congestion) there. If there is a great amount of pus in the eye, the eye may have to be washed out in this manner, every fifteen minutes, day and night, so that the cornea will be kept clean. If this must be done a small fountain syringe with a glass tube (eye dropper) attached will cause a steady flow of the solution. An attendant should not touch her face or hair with her hands unless they have been washed quite clean. The conjunctiva should be brushed with a solution of nitrate of silver of two per cent strength (two parts to one hundred of distilled water) and then neutralized with a salt solution, not strong enough to burn. When the cornea is diseased one per cent solution of atropine may be necessary once or twice a day. Persons who must be with the patient should be very careful not to get any of the discharge upon their clothes or person, as it is very contagious. The eyeball shows a ring of pink congestion about the cornea, with congestion of the conjunctiva. Infected ulcers may spread, or they may sink deeply into the substance of the cornea and eat through. There is apt to be more or less film over the eye for some time and if the ulcer eats through it may destroy the sight. Boric acid, as much as will dissolve in warm, distilled water and some dropped in the eye three or four times a day. If there is a foreign body in the cornea, clean instruments should be used to remove it. Hot fomentations repeated according to the severity of the case and the amount of "easing" they give. Alling says: "Dissect off the growth from the cornea and sclera coats, leaving the base attached (toward the corner of the eye) and bury its point under the undermined conjunctiva below. If the growth is dissected off the cornea, which may readily be done, and then cut off (towards its base) it would recur. On examination the lids are found swollen and red, the eyeball shows congestion in the cornea and ciliary body, with some congestion of the conjunctiva. The anterior surface of the iris looks muddy and does not look so fine and delicate. If atropine is put in the eye (one per cent solution) the pupil will not dilate regularly, because at different points the pupillary edge of the iris is held to the lens by an exudate that lightly holds it. This disease is said to be brought on by rheumatic fever, and rheumatism is a disease of the blood. Atropine usually made of about the strength of two to four grains Atropine to an ounce of water; or one per cent (1 to 100) may be used, and it should be dropped into the eye from three to six times a day. The pupil must be dilated and kept so from the beginning to keep the adhesions from forming between the iris and lens. If too much is used the throat and tongue will feel dry, face will flush, and there will be dizziness and a rapid pulse. The great danger is permanent adhesion of the iris to other parts, especially the lens, and the dilating and contracting power may be lost. This is due to paralysis of the sphincter muscle of the pupil, but it generally disappears. The edge of the pupil may be torn in the form of one or more rents, or the iris may be separated from its root at its circumference, leaving a clear space, or it may be entirely torn from its attachment. Perforating wounds are accompanied by injury to the lens and other structures; when the cornea is wounded it is often complicated by falling of the lens. When a small foreign body passes through the cornea and iris a small opening may be seen. The greatest danger from wounds is due to infection and if it reaches the iris, it may produce violent iritis. If the lens is displaced or absent the iris being without support, will tremble with every movement of the eye. In some cataract operations, if there is a loss of the "Vitreous" body a part of the iris may be folded upon itself, thus enlarging the pupil in that point. The lens looks a little whitish through the pupil opening and looks more so as time goes on. In this kind of cataract both eyes are affected sooner or later, although one eye may be fully matured before the other is much changed. There should be a homogeneous (all alike) white or gray opacity immediately back of the pupil, with no shadow from the edge of the pupil (except in cases of sclerosis, already mentioned). A candle carried on all sides of the patient while the eye is fixed, should be properly located by him. The patient should be ready and willing to place himself in the charge of the operator and do as he says. This is a rare disease, but it may occur when one eye is injured or diseased and on the first indication of trouble in the injured eye the other eye should be closely watched for symptoms of sympathetic trouble so that if can be removed. If it has appeared, enucleation will be of no value; at all events if there is vision in the exciting eye, the operation should not be done then. This may be very slight, when you consider the great changes occurring in the retina. Bleeding and shining white patches are scattered through the back part of the eye and a peculiar arrangement of glistening white dots around the yellow spot. It is unfortunate, but true, that even more children and grown people should wear them. When the eyes water and feel tired or strained, even after using them but little, glasses are needed. When glasses are needed it does not pay to put off getting them and the person needing them should go to one competent to properly fit them. A great many eyes are hard to fit, and they need not only ability to fit them well, but time and attention must be given to fitting them properly. An operation is necessary and the tendons on both sides must generally be cut and properly placed. The operation is not difficult to perform and it will not only, as a rule, give the child good sight, but better looks. Parents who are able to have an operation or glasses fitted when needed, and who neglect their children, should be punished; they are guilty not only of neglect, but cruelty. Apply this externally to the eyes, and it will be found very beneficial for this trouble. This trouble usually results from or is associated with constitutional disease and requires treatment for same, but the above wash is good for local applications. Care should be taken in using this remedy that none of the mixture gets into the eyes. I went to an eye specialist, and he gave me two little vials of medicine to drop into my eyes six times a day. I doctored with him several months, and while the medicine reduced the inflammation largely, it did not relieve the scratching sensation in the eyes. Then I was away from home for about ten days and did not use the medicine, and when I returned my eyes were very much inflamed, and very painful. I visited the doctor again, and he said I had a little ulcer on the eyeball, and he pulled out several hairs or winkers from the eyelid. Ever since then, when my eyes begin to hurt me as though there was some foreign substance in them, I go to my neighbor and he pulls out the wild hairs, and that was the trouble with my eyes. You can buy a small package of the slippery elm at any drug store, and prepare it by making a tea and using externally. In severe cases a poultice is useful, made of pulverized slippery elm and warm milk and water. All eye washes should be used with caution and especially those containing belladonna or caustic solutions," 8. Camphor water is made by allowing the gum to dissolve in water instead of alcohol, also saturate lint in this mixture and apply on the eyes. The canal leading in to the membrane (drum) is called the external auditory meatus. Membrane Tympani (drum) which separates the external ear from the tympanic cavity. To examine the drum, you must pull the ear backward and outward to make the canal straight. This membrane not only serves as a protection to the delicate structures within the tympanum, but also receives the sound vibrations from without and transmits them to the ossicular (bony) chain of the middle ear. It is filled with air and communicates with the nose-pharynx (naso-pharynx) by the eustachian tube. The upper portion of this cavity, the attic, lies immediately below the middle lobe of the brain, separated from it by a thin layer of bone, which forms the roof of the cavity. With an opening in the anterior of the middle ear, a bony canal passes from this point, inward, forward, and downward through the petrous bone, when it merges into a cartilaginous canal, which terminates in a funnel-shaped protuberance, with a slit-like orifice, located in the nose pharynx. The mucous membrane of the middle ear is continuous with that of the nose-pharynx through the eustachian tube. So you can readily understand how easy it is for an inflammation of the throat to extend to the middle ear through the eustachian tube. The posterior wall which has the greatest height, reveals in its upper portion a passage (antrum) through which the vault of the tympanum (attic) communicates with the cells of the mastoid process, situated posteriorly. From this description you see how near to each other these parts are placed and when one becomes diseased the disease can extend to the other part or parts. The brain is separated from some of these cavities by a very thin shell of bone, and the disease can soon affect the brain through infection or breaking through the thin structures that separates the parts. Diseases of the middle ear and the mastoid are always to be considered serious, and should be very closely watched. A child with a running ear is in danger, for it may at any time become closed up and serious. It develops in other parts of the body at the same time in a certain percentage of cases. There is a tendency to it in some families; stomach trouble, improper food are also causes. The part is somewhat reddened, fluid oozes out, crusts form, the skin thickens, and scales. Cloths dipped in some cooling lotion, such as the lead and opium wash, or in plain water to which has been added a little alcohol or eau de cologne, should be wrapped around the inflamed ear during the acute stage and they should be kept wet. Loss of hearing may take place suddenly, as after washing the head, or after a general bath, or after an attempt to clean the ear with the end of a towel. This no doubt was due to the fact that the mass of wax was displaced against the drum suddenly by an unusual movement of the head or the jaws, or the mass became swollen through fluids getting into the canal. If the canal is filled there will be more or less deafness, ringing in the ear, and there may be piercing pain produced by the hardened mass, especially if the jaws are moved from side to side.
