RESUMEN

This article's goal is to describe a case of oral contraceptives-related drug-induced gingival hypertrophy that was treated with nonsurgical and surgical periodontal therapy. The most prevalent negative side effect of systemic medicine on the periodontal tissues continues to be drug-induced gingival overgrowth. Specific regulatory molecules known as hormones control a variety of bodily processes. Gingival hypertrophies are sometimes linked to oral contraceptives that contain oestrogen and/or progesterone. A 32-year-old female presented with a complaint of swelling of the gingiva with spontaneous bleeding in the maxillary right quadrant region for a period of two months. The medical history documented the use of contraceptives for three months, and a clinical examination revealed the existence of poor oral hygiene and enlarged painful gingival tissues that bled when touched. Intraoral examination revealed that there was unilateral, generalized, diffuse gingival enlargement with pseudo pockets. Patient was diagnosed with gingival fibromatosis a based on the clinical, histological, and radiographic findings. The gingival enlargement was treated by conventional gingivectomy under local anaesthesia. The postoperative result was uneventful. Women who use oral contraceptives are a "risk group" for periodontal infections. On oral contraceptives, not every female reacts the same way. In periodontal therapy, plaque management is the most crucial step. Patient compliance is another element that affects a therapy's response. The patient demonstrated appropriate oral hygiene practices and adhered to home care guidelines adequately.

RESUMEN

BACKGROUND: Following malaria elimination, Sri Lanka was free from indigenous transmission for six consecutive years, until the first introduced case was reported in December 2018. The source of transmission (index case) was a member of a group of 32 migrant workers from India and the location of transmission was their residence reporting a high prevalence of the primary vector for malaria. Despite extensive vector control the situation was highly susceptible to onward transmission if another of the group developed malaria. Therefore, Mass Radical Treatment (MRT) of the group of workers for Plasmodium vivax malaria was undertaken to mitigate this risk. METHOD: The workers were screened for malaria by microscopy and RDT, their haemoglobin level assessed, and tested for Glucose 6 phosphate dehydrogenase deficiency (G6PD) using the Care Start RDT and Brewers test prior to treatment with chloroquine (CQ) 25 mg/kg body weight (over three days) and primaquine (PQ) (0.25 mg/kg/day bodyweight for 14 days) following informed consent. All were monitored for adverse events. RESULTS: None of the foreign workers were parasitaemic at baseline screening and their haemoglobin levels ranged from 9.7-14.7 g/dl. All 31 individuals (excluding the index case treated previously) were treated with the recommended dose of CQ. The G6PD test results were inconclusive in 45% of the RDT results and were discrepant between the two tests in 31% of the remaining test events. Seven workers who tested G6PD deficient in either test were excluded from PQ and the rest, 24 workers, received PQ. No serious adverse events occurred. CONCLUSIONS: Mass treatment may be an option in prevention of reintroduction settings for groups of migrants who are likely to be carrying latent malaria infections, and resident in areas of high receptivity. However, in the case of Plasmodium vivax and Plasmodium ovale, a more reliable and affordable point-of-care test for G6PD activity would be required. Most countries which are eliminating malaria now are in the tropical zone and face considerable and similar risks of malaria re-introduction due to massive labour migration between them and neighbouring countries. Regional elimination of malaria should be the focus of global strategy if malaria elimination from countries is to be worthwhile and sustainable.

RESUMEN

Leukocyte inflammatory responses require integrin cell-adhesion molecule signaling through spleen tyrosine kinase (Syk), a non-receptor kinase that binds directly to integrin ß-chain cytoplasmic domains. Here, we developed a high-throughput screen to identify small molecule inhibitors of the Syk-integrin cytoplasmic domain interactions. Screening small molecule compound libraries identified the ß-lactam antibiotics cefsulodin and ceftazidime, which inhibited integrin ß-subunit cytoplasmic domain binding to the tandem SH2 domains of Syk (IC50 range, 1.02-4.9 µM). Modeling suggested antagonist binding to Syk outside the pITAM binding site. Ceftazidime inhibited integrin signaling via Syk, including inhibition of adhesion-dependent upregulation of interleukin-1ß and monocyte chemoattractant protein-1, but did not inhibit ITAM-dependent phosphorylation of Syk mediated by FcγRI signaling. Our results demonstrate a novel means to target Syk independent of its kinase and pITAM binding sites such that integrin signaling via this kinase is abrogated but ITAM-dependent signaling remains intact. As integrin signaling through Syk is essential for leukocyte activation, this may represent a novel approach to target inflammation.

RESUMEN

BACKGROUND: There has been no local transmission of malaria in Sri Lanka for 6 years following elimination of the disease in 2012. Malaria vectors are prevalent in parts of the country, and imported malaria cases continue to be reported. The country is therefore at risk of malaria being re-established. The first case of introduced vivax malaria in the country is reported here, and the surveillance and response system that contained the further spread of this infection is described. METHODS: Diagnosis of malaria was based on microscopy and rapid diagnostic tests. Entomological surveillance for anophelines used standard techniques for larval and adult surveys. Genotyping of parasite isolates was done using a multi-locus direct sequencing approach, combined with cloning and restriction fragment length polymorphism analyses. Treatment of vivax malaria infections was according to the national malaria treatment guidelines. RESULTS: An imported vivax malaria case was detected in a foreign migrant followed by a Plasmodium vivax infection in a Sri Lankan national who visited the residence of the former. The link between the two cases was established by tracing the occurrence of events and by demonstrating genetic identity between the parasite isolates. Effective surveillance was conducted, and a prompt response was mounted by the Anti Malaria Campaign. No further transmission occurred as a result. CONCLUSIONS: Evidence points to the case of malaria in the Sri Lankan national being an introduced malaria case transmitted locally from an infection in the foreign migrant labourer, which was the index case. Case detection, treatment and investigation, followed by prompt action prevented further transmission of these infections. Entomological surveillance and vector control at the site of transmission were critically important to prevent further transmission. The case is a reminder that the risk of re-establishment of the disease in the country is high, and that the surveillance and response system needs to be sustained in this form at least until the Southeast Asian region is free of malaria. Several countries that are on track to eliminate malaria in the coming years are in a similar situation of receptivity and vulnerability. Regional elimination of malaria must therefore be considered a priority if the gains of global malaria elimination are to be sustained.

RESUMEN

BACKGROUND: Sri Lanka has achieved 'malaria-free' status and is now in the phase of prevention of re-introduction of malaria. Imported malaria remains a challenge to resurgence of the disease. The diagnostic challenges encountered and the rapid response initiated to manage a Plasmodium infection, which was later confirmed as Plasmodium knowlesi, the first reported case from Sri Lanka, is discussed. CASE PRESENTATION: An army officer who returned from Malaysia in October 2016 was found to be positive for Plasmodium both by microscopy and rapid diagnostic test (RDT) by the Anti Malaria Campaign Sri Lanka (AMC) during his third visit to a health care provider. Microscopy findings were suspicious of P. knowlesi infection as the smears showed parasite stages similar to both Plasmodium malariae and Plasmodium falciparum. Nested PCR at AMC confirmed Plasmodium genus, but not the species. In the absence of species confirmation, the patient was treated as a case of P. falciparum. The presence of P. knowlesi was later confirmed by a semi-nested PCR assay performed at the Environmental Health Institute, National Environmental Agency in Singapore. The parasite strain was also characterized by sequencing the circumsporozoite gene. Extensive case investigation including parasitological and entomological surveillance was carried out. CONCLUSIONS: Plasmodium knowlesi should be suspected in patients returning from countries in the South Asian region where the parasite is prevalent and when blood smear results are inconclusive.

RESUMEN

BACKGROUND: Work-related diseases and occupational accidents affect a significant number of workers globally. The majority of these diseases and accidents are reported from developing countries; and a large percentage of the workforce in developing countries is estimated to be employed in small-scale industries. Sri Lanka is no exception. These workers are exposed to occupational hazards and are at a great risk of developing work- related diseases and injuries. OBJECTIVE: To identify occupational health issues faced by small-scale industry workers in Sri Lanka. METHODS: A cross sectional study was conducted among workers in four selected small-scale industry categories in two districts of Sri Lanka. A small-scale industry was defined as a work setting with less than 20 workers. Cluster sampling using probability proportionate to size of workers was used. Eighty clusters with a cluster size of eight from each district were selected. Data was collected using a pre-tested interviewer administered questionnaire. RESULTS: Our study surveyed 198 industries. Headache (2.2%, 95% CI 1.5-3.1) and eye problems (2.1%, 95% CI 1.4-2.9) were the commonest general health issues detected. Back pain (4.8%, 95% CI 3.8-6.1) was the most prevalent work-related musculoskeletal pain reported. Knee pain was the second highest (4.4%, 95% CI 3.4-5.6). Most of the work-related musculoskeletal pain was either of short duration or long lasting. CONCLUSIONS: Work-related musculoskeletal pain was much more common than the general health issues reported. Health promotional programs at workplaces focusing ergonomics will benefit the workers at small-scale industries inSri Lanka.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate if the addition of a decision aid (DA) decreases decisional conflict in women presenting for the management and treatment of pelvic organ prolapse (POP). METHODS: Women scheduled for the evaluation and management of POP were randomized into either of 2 groups: standard counseling (SC) alone (n = 51) or SC plus a DA (n = 53). Upon completion of their initial visit, patients filled out a 16-item decisional conflict scale and short form general health survey. Values were assessed for normality and compared between groups. Normally distributed, continuous data were evaluated with a Student t test. A χ2 test was used to compare selected categorical characteristics between groups. Differences in distributions of low and high decisional conflict were assessed with a Mann-Whitney U test. RESULTS: One hundred four women were randomized for this analysis. Baseline characteristics, including pelvic prolapse examination measurements, did not significantly differ between groups. The addition of a DA to SC did not significantly lower the level decisional conflict patients faced when deciding on a treatment plan (P = 0.566). There were no significant differences between groups in the following subscores: uncertainty, values clarity, support, effective decision, and informed. In addition, there were no between-group differences in choice of treatment plan (conservative management, pelvic floor physical therapy, pessary, and surgery; P = 0.835). CONCLUSIONS: In this relatively small sample, the addition of a DA to SC for women with POP does not significantly decrease the level of decisional conflict in making treatment-related decisions.

RESUMEN

OBJECTIVE: To evaluate trends in surgical approach for sacral colpopexy since the advent of robotic technology for gynecologic procedures. STUDY DESIGN: Women who underwent surgery for uterovaginal prolapse, cystocele, and/orvaginalvault prolapse were included in this study. The number of patients undergoing a vaginal approach for prolapse was compared to the number of patients receiving sacral colpopexy. Descriptive statistics comprised means and standard deviations, while categorical data were reported as frequencies. Inferential statistics comprised Student's t-test for assessing two-group differences between means ofcontinuous, normally distributed data and chi-squared tests for comparisons of equality of distribution between categorical variables. RESULTS: Patients undergoing sacral colpopexy were younger than their vaginal surgery counterparts (P< 0.001). When stage ofprolapsewas dichotomized, among those with stage 1-2 prolapse, a greater percentage of patients received colpopexy in favor of vaginal surgery in 2010 than in 2007 (P=0.001). CONCLUSION: There is an increasing trend towards robotic-assisted sacralcolpopexyforthe management of apical prolapse.

RESUMEN

OBJECTIVE: To determine the prevalence of asymptomatic microscopic hematuria (AMH) in patients with pelvic organ prolapse. METHODS: The Urogynecology patient database was reviewed for patients presenting between July 2010 and April 2011 inclusive. We compared the prevalence of AMH in patients with no prolapse with those with prolapse. A post-hoc analysis was performed to evaluate if overall stage of prolapse was related to the presence of AMH. Pearson chi-square analysis was used for categorical variables, and P values<.05 were deemed statistically significant. RESULTS: Of the 230 women with evaluable AMH data, 29 (12.6%) had AMH. Baseline patient demographic data did not significantly differ between groups. Women with prolapse had a higher prevalence of AMH compared with women with no prolapse (18.3% vs 5.1%, P=.003). There was a significant difference in the distribution of AMH by stage of prolapse, with AMH more prevalent among women with higher stages of prolapse (P=.007). CONCLUSION: Women with prolapse beyond the hymen have a significantly higher prevalence of AMH when compared with women with prolapse at or above the hymen. We suggest an overall rate of AMH in the Urogynecologic population of 12.6%.

RESUMEN

OBJECTIVES: The literature states that patients with pelvic organ prolapse have a higher prevalence of bothersome bowel symptoms and that surgical correction of prolapse may improve bowel function. There is limited knowledge regarding the impact of pessary use on bowel function in patients with prolapse. The aim of this study was to evaluate if there is a change in bowel symptoms in patients with prolapse treated with a vaginal pessary. METHODS: Women who presented for pessary insertion completed the validated questionnaires on the bowel symptom severity and on the effect of bowel symptoms on the quality of life at baseline and again at 12 months of continuous pessary use. Inferential statistics comprised Student t test for evaluating differences in continuous Gaussian data between groups and paired t tests were used to evaluate differences among subjects between the baseline and 12 months of use. RESULTS: One hundred four women participated in the original study, and 43 had complete data for analysis. Women who completed 12 months of pessary use reported significant improvements in both bowel-related symptoms and bowel-related quality of life (95% confidence interval of the difference 1.6-11.4 and 2.0-14.0, respectively). Patients who completed the 12-month follow-up were significantly older and more likely to have stage 3 or 4 prolapse than noncompleters, but there were no differences in body mass index, race, history of prior prolapse surgery, or menopause status. CONCLUSIONS: In women with prolapse, the use of a pessary is associated with a decrease in complaints related to bowel symptoms.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to evaluate if the impact of urinary incontinence (UI) on quality of life (QOL) differs between women based on age. METHODS: A retrospective review of patients presenting for the management of UI was performed. Patients with UI and their corresponding degree of bother were identified by their responses to validated questionnaires. Distributions of comorbidities and types of UI were presented as frequencies and compared between age cohorts with a chi-square test. Mean scale scores were assessed for normality and a one-way analysis of variance with a post hoc Scheffé's test was used to compare the scores. RESULTS: Of 765 patients meeting inclusion criteria, 22.4 % were <45, 28.9 % were 45-55, and 48.8 % were >55 years of age. Women older than 55 were significantly more likely to have urge UI and mixed UI than their counterparts (p < 0.001). Women <45 and 45-55 were more negatively impacted in their ability to perform physical activities compared to women >55 (p = 0.004), whereas women >55 were significantly less likely to feel frustrated by their incontinence than women <45 (p = 0.022). However, there was no significant difference in overall impact of incontinence among groups (p = 0.585). CONCLUSIONS: UI equally impacts the functional and psychological QOL in women regardless of age. UI in women <55 results in a greater negative impact on level of physical activity, whereas women <45 are significantly more frustrated.

RESUMEN

OBJECTIVE: The purpose of this study was to evaluate the pressure placed on the shoulders as a function of varying degrees of head-down tilt (the Trendelenburg position) and to compare these pressures among 3 different patient-positioning systems. STUDY DESIGN: Participants were placed in the dorsal-lithotomy position with arms tucked and tilted at 5, 10, 15, 20, 25, and 30 degrees of head-down tilt. Using a manometer, we measured the pressure (centimeters of water) on the shoulders at each angle for 3 support devices: the Skytron shoulder support (Skytron, Grand Rapids, MI), the Allen shoulder support (Allen Medical Systems, Acton, MA), and the Allen Hug-u-Vac. RESULTS: Among 23 participants, body mass index (mean ± SD) was 24.5 ± 4.3 kg/m(2). As the tilt angle increased, so did the shoulder pressure for all support systems. At a 30-degree Trendelenburg position, the Allen Hug-u-Vac transmitted less pressure to the shoulders than the Skytron (right and left, P < .001) and the Allen shoulder supports system (right, P < .001; left, P = .434). Each participant was asked, "Which system was most comfortable?" Seventy-four percent of the participants reported that they preferred the Hug-u-Vac (P < .001). CONCLUSION: Shoulder pressure increases as tilt angle increases. Of the 3 support systems that were tested, the Allen Hug-u-Vac transmitted less pressure to the shoulders at a 30-degree Trendelenburg position than the Skytron and the Allen shoulder support systems.

RESUMEN

OBJECTIVE: We sought to evaluate the prevalence of pelvic organ prolapse (POP) among a diverse group of women and to determine if race/ethnicity and/or socioeconomic status (SES) are factors in treatment-seeking behavior. STUDY DESIGN: All data were collected from the National Institutes of Health-supported Boston Area Community Health Survey. SES was calculated by a 2-factor index that combined household income with years of education. Inferential statistics comprised 1-way analysis of variance, with a post hoc Scheffé test performed to evaluate whether there were differences between individual groups. A χ(2) test was used to evaluate whether distributions were equal among the various questions by race/ethnicity and SES category. RESULTS: A total of 3205 women were included in the analysis. Hispanic ethnicity and younger age were associated with POP (P < .002 and P < .001, respectively) as well as with seeking treatment for prolapse (P = .007 and P < .001, respectively). These factors were also associated with subsequent surgical repair (P = .027 and P = .019, respectively). A regression model showed that women were 4.9% more likely to seek treatment for every year younger they were, across the range of age. Although women of a higher SES were more likely to have POP, SES was neither associated with a higher likelihood of seeking treatment nor with the surgical management of prolapse. CONCLUSION: Hispanic ethnicity and younger age were associated with seeking treatment for POP. Hispanics were more likely than whites or blacks to proceed with surgical management. There was no correlation of SES with any of the above factors.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to determine if anesthesia with neuromuscular blockade alters the Pelvic Organ Prolapse Quantification (POP-Q) examination. METHODS: A prospective, multi-center trial was conducted of women undergoing pelvic surgery. A POP-Q examination performed pre-operatively was compared with an examination performed intra-operatively under neuromuscular blockade. For the latter examination, an Allis clamp was used to apply gentle traction until the point being examined did not undergo further descent. International Continence Society (ICS) stages and individual POP-Q points were compared using a paired sample t test. A sample size of 32 provided 80% power to detect a clinically significant difference between office and operating room measurements (Sample Power, SPSS, 1997). RESULTS: Of 153 women, 76% received general endotracheal anesthesia and 21% laryngeal mask airway. With an increase of 3 cm, the apical compartment was significantly more prolapsed in the operating room (OR; p < 0.05); however, a comparison of the mean values demonstrated a larger change in means for all points except total vaginal length. When separated into anterior, apical, and posterior compartments, the ICS stages were systematically different in the OR than in the office for all stages (p < 0.0005). CONCLUSIONS: Neuromuscular blockade leads to significantly greater increases in POP-Q examination measurements compared with the office measurements, and this increase is most pronounced apically.

RESUMEN

BACKGROUND: Youth with type 1 diabetes cope with a variety of stressors related to daily life and disease management. While previous studies have focused on diabetes-related stressors, little research has examined daily stressors. METHODS: In this qualitative descriptive study, daily stressors and coping responses of 19 children and 33 adolescents with type 1 diabetes (65% are female) were investigated. Participants recorded their own stressors and coping responses in daily diaries for 2-3 weeks. RESULTS: Five broad themes of daily stressors emerged: people, self, context, no stressor and ambiguous. Coping responses included three general themes: submission, personal responsibility and ambiguous. Younger children reported more stressors related to friends/peers and siblings (people), and adolescents described more stressors related to self, parents (people) and school (context). Younger children used more coping that involved choosing an alternate activity, helping others and an emotional response (taking personal responsibility), whereas adolescents used more coping that involved persistence, alternate thinking and talking things over (taking personal responsibility). CONCLUSIONS: Youth with diabetes did not report stressors related to diabetes and its management as major themes in their daily lives. Clinical interventions based on perceptions of how youth understand and cope with stress are explored.
