Non-Surgical Endodontic Therapy as Treatment of Choice for a Misdiagnosed Recurring Extraoral Sinus Tract.

ABSTRACT: The purpose of this article is to present the treatment of an odontogenic cutaneous sinus tract with exuberant extraoral granulation tissue and its successful endodontic treatment and follow up with Cone-Beam Computed Tomography (CBCT). In this case, a 31-year-old woman was referred for management of a reddish nodule on her chin. Previous surgical and antibiotic intervention by the dermatologist had not resolved the problem. Profound clinical and radiological examination (including CBCT) revealed apical periodontitis of tooth 32 to be the cause of the recurring cutaneous sinus tract. Conservative non-surgical root canal treatment was performed. With the aid of a topical corticosteroid and supplemental antibiotic therapy, healing of the apical periodontitis and resolution of the granulation tissue was evident after 1 year both clinically and radiographically. This case report emphasises the need for more awareness by dermatologists and other medical practitioners for the differential diagnosis of extraoral sinus tracts. Correct diagnosis of the dental cause can prevent unnecessary and multiple antibiotic and surgical interventions. Antibiotic therapy should never be administered without addressing the underlying dental cause. Conservative non-surgical endodontic treatment is the treatment of choice for an extraoral sinus tract of endodontic origin.

Project description:One in three women will experience a clinically significant urinary tract infection (UTI) by age twenty-four and almost half will have at least one in their lifetime. Recurrent UTIs (rUTIs) are defined as having greater than two infections in a 6-month period, or three infections over twelve months, with complete resolution for at least two weeks. These may be due to relapse from incomplete treatment (persistence) or re-infection (new source). It may be difficult to distinguish between the two, where the same organism is cultured. There are several risk factors for rUTIs including an impairment of the body's immune system and virulence factors. Reversible or treatable causes are sought and excluded in the patient's initial review. Patient's with rUTI are often complex and difficult to manage. The long-term management options in women are multimodal and should focus on prevention of relapse and recurrence. Behavioural factors include adequate hydration, care with sexual hygiene, reducing one's body mass index (BMI) and post-void residual (PVR) volume. There are several non-antimicrobial options for rUTIs which have become a multi-billion-dollar business. Unfortunately, there are numerous studies which fail to show any major benefit or having conflicting data. Vaccines are currently being explored as a prevention strategy, delivered through injection, intra-nasal sprays, or vaginal suppositories, which are made from combinations of heat killed uro-pathogenic strains. There are no widely available vaccines at present due to limited clinical success. It is well established that appropriate antibiotic therapy results in higher rates of symptom relief and bacterial eradication in women with uncomplicated cystitis. There are several options for antimicrobial use which have been shown to be highly effective in reducing the risk of rUTI in women. The pain and discomfort of the UTI must be balanced with the cost and risk of developing resistance when using antimicrobials. Continuous prophylaxis, pre- and post-coital voiding, and self-starting are the three commonly accepted options for prophylaxis. The choice between these will depend upon patient preference, cultures and previous pattern of infection. Intra-vesical instillation of hyaluronic acid and chondroitin sulphate have been used for glycosaminoglycan (GAG) layer replenishment for many indications, including interstitial cystitis, overactive bladder syndrome, radiation cystitis and prevention of rUTI. At present, intra-vesical therapies are reserved for only those with the most unresponsive rUTIs. The principles of treating rUTI are to break the cycle and to treat any reversible causes. With our ever-expanding research knowledge, there are now many useful products that may be used for the successful treatment of rUTI. A management plan including a combination of a non-antimicrobial and selective antimicrobial regime for a minimum of six months should be considered. It is a prudent clinician that clearly defines this management plan, with reassurance of a finite period of therapy.

Project description:BackgroundThe sinus lift (or sinus augmentation) is a common procedure to improve maxillary bone stock before dental implantation. Chronic rhinosinusitis (CRS) is a potential complication of this procedure and may be refractory to medical treatment. Functional endoscopic sinus surgery has previously been used to address CRS, however, results of previous studies indicated that implant removal is required. There are limited follow-up data available.ObjectiveThe purpose of this study was to characterize the long-term outcomes and efficacy of endoscopic sinus surgery for refractory CRS after sinus lift, including the ability to salvage dental implants.MethodsThis was a retrospective case series that described nine patients who, between June 2011 and September 2016, underwent endoscopic sinus surgery for CRS after a sinus lift procedure. The presenting symptoms of the patients, medical management, imaging results, operative procedures, and outcomes were reviewed.ResultsThe majority of patients developed symptoms (mucopurulent nasal drainage, facial pain and/or pressure, nasal congestion, and foul smell) within 3 months of implant placement and were treated with at least three courses of antibiotics before referral to an otolaryngologist. All the patients underwent wide endoscopic maxillary antrostomy, with no surgical complications or postoperative reports of infection. There was a statistically significant improvement in 22-item Sino-Nasal Outcome Test scores (t(8) = -2.908; p = 0.02) and discharge, inflammation, and polyps/edema endoscopic scores ([z = -2.539; p = 0.011) between pre- and postsurgical treatment. Four patients had their dental implants removed before presentation. Among the five patients who presented with intact dental implants, none required removal before or after functional endoscopic sinus surgery.ConclusionFunctional endoscopic sinus surgery was a reasonable and efficacious treatment option for patients who presented with paranasal sinus disease after a sinus lift. Dental implant removal may not be a requirement for successful treatment of CRS associated with sinus lift procedures.

Project description:BackgroundThe guideline on urinary tract infections (UTI) of the Dutch College of General Practitioners provides recommendations on patient-initiated treatment and prevention of recurring UTI.AimTo study familiarity with self-management skills for prevention of recurring UTI amongst adult women.Design and settingsAn online questionnaire was developed, based on the UTI guideline and interviews with women having recurring UTI. Pharmacists in a postgraduate education programme (N = 76) aimed to invite 10 adult women with a recurring UTI prescription to complete the questionnaire. Women were asked for informed consent to link medication record data to questionnaire data.MethodWe calculated proportions of the scores for self-management skills and analysed differences between age groups with chi-square test.ResultsComplete questionnaires were available for 719 women (mean age 55.1 ± 18.5 years). The proportions of women 18-50 years and women 51 years or older were 36.4% and 63.6%, respectively. Education levels of women 18-50 years were significantly higher than those of women 51 years and older. Before consulting a general practitioner (GP) for symptoms, 32.1% of all women increased fluid intake; additionally, 15.0% used analgesics and increased fluid intake. Of all women, 33.9% searched internet for information on self-management and 18% occasionally received a prescription for patient-initiated treatment, half of these prescriptions for use during vacation. Cranberry was used by 47%, d-mannose by 5% and vitamin C by 29% of all women. Awareness of different preventive behavioural measures (eg, fluid intake, washing without soap and emptying bladder after sexual intercourse) varied between 20% and 90%.ConclusionAlmost half of all women applied self-management (increased fluid intake, analgesics) before consulting a GP for recurring UTI. Awareness of preventive behavioural measures for recurring UTI varied considerably. Thus, education of women about the use of analgesics and behavioural measures deserves attention.

Project description:BackgroundChronic rhinosinusitis is an inflammatory disorder in which the role of bacteria remains uncertain. While sinus outflow obstruction is often an initiating event, mucosal inflammation and dysbiosis may persist or develop in sinuses with widely patent surgical openings. Understanding of the relationship between dysbiosis and chronic sinus inflammation is obfuscated by inter-individual microbiota variability and likely intra-individual temporal variation that has yet to be defined. In this study, long-term microbiota stability is investigated within surgically-opened maxillary sinuses of individuals with and without sinus inflammatory disease.MethodsMaxillary sinus swabs were performed in 35 subjects with longstanding maxillary antrostomies. Subjects with and without active chronic maxillary sinusitis were included. Repeat swabs were obtained from the same sinuses after a prolonged interval (mean 719 ± 383 days). Patients were categorized based on the inflammatory status of the sinus mucosa at times of sample collection, as assessed by nasal endoscopy. Total DNA from swab eluents was extracted, and the microbiota characterized using 16S rRNA gene sequencing followed by taxonomic classification. Prevalence and abundance of genera were determined by analysis of 16S rRNA gene sequences. Taxa were identified that were stably present between two time points in individual subjects.ResultsThe overall proportion of stable taxa across time points was 24.5 ± 10.6%. This stability index was consistent across patient groups and not correlated with clinical parameters. Highly prevalent taxa, including Staphylococcus, Corynebacterium, Propionibacterium, and Pseudomonas, were often stably present, but varied in relative abundance. Janthinobacterium, Enterobacter, Lactobacillus, and Acinetobacter were prevalent and moderately abundant taxa in healthy sinuses, but not in inflamed sinuses. Moraxella and Haemophilus were present at low prevalence and proportional abundance in chronically or intermittently inflamed sinuses, but not in healthy sinuses.ConclusionsA relatively small component of the post-antrostomy maxillary sinus microbiota exhibits long-term stability in individual subjects. Stable bacteria include a limited number of highly prevalent and a larger number of lower prevalence taxa, which vary widely in proportional abundance. The concept of individual-specific core sinus microbiota, durable over time and medical therapy, but fluctuating in proportional abundance, has implications for understanding the role of bacteria in CRS pathogenesis.
