Causes of post treatment apical periodontitis

Endodontic treatment approaches aim to achieve proper treatment and prevention of apical periodontitis to enhance the oral health status and enhance the prognosis of affected teeth. However, many complications can develop secondary to endodontic treatment. The management of post-treatment apical periodontitis might be challenging to clinicians, and the prognosis is usually lower than that of primary apical periodontitis. Therefore, identifying the potential etiology and intervening against them might be ideal for these cases. The present literature review discusses the commonest causes reported in the literature to predispose to the development of post-treatment apical periodontitis. Most of the various investigations in the literature indicate that post-treatment apical periodontitis is usually caused by either extraradicular or intraradicular infections, like primary apical periodontitis. However, it should be noted that some studies also reported that technical or procedural errors might predispose to the pathogenesis of the condition. However, it has been reported that the presence of associated bacterial infection conditions this.

Greywater as an Alternative Solution for a Sustainable Management of Water Resources—A Review

In this paper, a comprehensive review on greywater is presented. Emphasis is given to the techniques used to treat and recover greywater, and special emphasis is placed on the risk of the existence of the novel coronavirus “SARS-CoV-2” in greywater and the possibility of its spread via the reuse of this water. In general, greywater is considered wastewater collected from domestic sources, with the exclusion of toilet water (which is considered as blackwater). Greywater represents 50 to 80% of the total volume of wastewater all over the world. This review provides various aspects related to greywater, such as origins, characteristics, and existing guidelines for greywater proper treatment and reuse. Several approaches and techniques have been developed to study the performance of different greywater treatment systems. These methods are critically discussed in this article. In the context of sustainable development, water management, and taking into account the scarcity of water resources, particularly in arid and semi-arid areas, the use of treated greywater is one of the alternatives methods that can reduce the burden of withdrawals from the resource. In addition, some successful examples of greywater valuation experiences in Tunisia were examined.

Canalis sinuosus approximation on an impacted maxillary canine: a case report

Objectives: This case report is aimed to report the finding of canalis sinuosus on an impacted maxillary canine using cone beam computed tomography (CBCT) examination. Case Report: A 21-year-old male was referred from orthodontic department to radiology department UNPAD Dental Hospital for CBCT to determine the treatment of malalignment asymptomatic maxillary canine. The case revealed the presence of canalis that was identified as a canalis sinuosus, a branch of the anterior superior alveolar nerve that rarely known by a practitioner, at the apex of impacted right maxillary canine. Conclusion: The information of this anatomical variation is important for professionals due to damage that may be caused during treatment. The use of advanced imaging examination is recommended to acknowledge the individual anatomical variation before determining the proper treatment planning.

Treatment of Winery Wastewater with a Combination of Adsorption and Thermocatalytic Processes

The release of winery wastewater (WW) into the environment, without proper treatment, can cause severe problems to freshwater quality and natural fauna and flora. Therefore, in this work a treatment process was studied, combining adsorption and thermocatalytic oxidation processes. In a more specific way, it optimized the combination of activated sodium bentonite (Na-Mt) and potassium persulfate (KPS)/sodium percarbonate (SPC) as oxidant agents. With the combination of best operational conditions of adsorption ([Na-Mt] = 5.0 g/L, pH = 3.0, V = 500 mL, agitation 350 rpm, T = 298 K, t = 24 h) and thermocatalytic oxidation processes (/H2O2 ratio = 1:0.25, /H2O2 dosage = 0.1:0.025 (g/g), pH = 7.0, T = 343 K, agitation 350 rpm, t = 2 h), a total organic carbon, chemical oxygen demand and total polyphenols removal of 76.7, 81.4 and >99% was achieved, respectively. Finally, it was evaluated the effect of the treatment processes in the germination index (GI) of different plant seeds. A GI > 80% was achieved, showing a low phytotoxicity effect of the processes applied in the winery wastewater treatment.

EMPOWERMENT ON THE CAPABILITY OF THE BARANGAY TANODS OF MARIA THERESA, CABANATUAN CITY

This study was conducted to determine on how to empower the capability of the barangay tanods of Maria Theresa, Cabanatuan City. After assessing their level of familiarity on the policing strategies as to Gender-sensitivity and Child-friendly approaches, the researcher proposed some programs on how to empower them. The researcher used a descriptive design of methodology. The outcome of the study have manifested that the barangay tanods have limited knowledge on the process in dealing with victims of violence against women. Further, as to child-friendly approach, the respondents were likewise slightly familiar on the proper treatment in handling child in conflict with the law. As a result, there is a need to empower the capability of the barangay tanods in performing their duties especially on how to become a Gender-sensitive and child-friendly barangay tanod. KEYWORDS: Empowerment, Capability, Barangay Tanod, Gender-Sensitivity Approach, Child-Friendly Approach, Maria Theresa

Beware of the Impostors—Scalp Pathology Primer for the Hair Transplant Surgeon

Histopathological features are important for the practicing hair transplant surgeon to ensure proper case selection, diagnosis, choice of proper treatment, and successful outcome. While the primary focus of the hair transplant surgeon is androgenetic alopecia (AGA), it is important to be aware of other conditions that can mimic AGA, whose treatment may be different. This article outlines some of these conditions such as scarring alopecias, alopecia areata, etc., and how to distinguish them. Proper identification will ensure proper treatment and avoid potential missteps in management.

Modern knowledge on pathogenesis, diagnosis and treatment of helicobacter infection

Since its discovery, H. pylori infection is known as one of the risk factor for the development of gastritis, peptic ulcer, GIT tumors and numerous other diseases such as psoriasis. Infection caused by H. pylori is posed as the top oncogene in the risk of the development of gastrocarcinoma (First class oncogene by Classification of International Agency for Research of Cancer). That is why the elaboration of fast and accurate methods of diagnosis (non-invasive methods especially) and proper treatment of Helicobacter infection is still very important. Throughout the time, knowledge about pathogenesis of Helicobacter infection have been expanded with the detection of adhesins, chemotaxins and multiple virulence factors related to invasion, adhesion and cytotoxicity of H. pylori. Invasive and non-invasive methods of diagnostics are currently being improved in effectiveness and accuracy. But still, due to different factors (e. g., dramatically increasing drug resistance), eradication of H. pylori remains big problem world-wide. Our review represents modern data on pathogenesis, diagnostics and treatment of Helicobacter infection.

Understanding the Dialogical Experiences of Puerto Rican Women With Fibromyalgia: An Intersectional Analysis

Introduction: Fibromyalgia is a condition that is often misunderstood by the medical community. Misunderstandings are exacerbated when a patient is an ethnic minority, and recent literature suggests that ethnic minorities are shown to have a higher prevalence of fibromyalgia. Despite this information, many studies about fibromyalgia are conducted with Anglo-Americans while ethnic minorities are underrepresented. Methods: To address this research gap, this study uses qualitative interviews to discuss the dialogical experiences of Puerto Rican women with fibromyalgia through a combination of intersectional and rhetorical theory. These methodologies can reveal what having various identities can mean when communicating in institutional and cultural settings. Results: The data shows a significant level of gaslighting by providers, which led participants to more aggressively seek proper treatment. Cultural deference towards doctors was also noted as a practice that can backfire, especially when living with a condition that is often dismissed. Conclusion: The results indicate that when the body's truth is filtered through intersectional lenses, this truth can become distorted or lost.

Cosmetic contact lenses: beauty can be blinding

Background: Although cosmetic contact lenses are ideally indicated for patients with corneal and iris abnormalities, they are currently fashionable among the younger generation of emmetropes to enhance their physical appearance. Cosmetic contact lens wearers carry a greater risk of microbial keratitis, even more so with counterfeit ones.Case presentation: Here, we report two cases of counterfeit cosmetic contact lens wearers with Acanthamoeba keratitis (AK) who were misdiagnosed as herpes simplex virus (HSV) keratitis.Conclusion: AK is a sight-threatening complication among contact lens wearers. Since clinically AK may masquerade as HSV, early diagnosis of AK is often delayed. As both microorganisms can mimic each other, determining the co-existence of both infections can be challenging. Delay in initiating proper treatment can lead to blinding complications.
