Tubeless field anaesthesia for surgical removal of an aspirated endoscopy capsule.

Capsule endoscopy is a safe, minimally invasive procedure used to investigate gastrointestinal bleeding of unknown origin that persists or recurs after a negative initial endoscopy. The most common adverse effects of capsule endoscopy include abdominal pain, nausea and vomiting. Capsule pulmonary aspiration, although a rare complication, has been reported in the literature. Most reported cases resolve without further medical intervention. In these cases, the capsule is either expelled by coughing, or it re-enters the oropharynx and is then swallowed. In a small number of cases, the capsule remains in the lung, unable to be expectorated. This requires prompt diagnosis and emergency bronchoscopic removal under general anaesthesia. Due to the smooth, rounded surfaces of the capsule, it may be difficult to grasp, and consequently extraction may be technically challenging. The existing literature contains limited documentation on anaesthetic and surgical approaches for managing an aspirated endoscopy capsule. In this case report, we present the management of an aspirated endoscopy capsule in a district general hospital, in which thoracic surgery was not available. Local resources were used to manage this potentially life-threatening complication without patient transfer. In our case, we provided a tubeless field to optimise surgical access. This facilitated the successful surgical extraction of the endoscopy capsule from the left main bronchus.

Role of cyclin-dependent kinase 4/6 inhibitors in the current and future eras of cancer treatment.

Cyclin-dependent kinase 4/6 inhibitors, which act by inhibiting progression from the G1 to S phases of the cell cycle, include palbociclib, ribociclib, abemaciclib, and trilaciclib. Palbociclib and ribociclib are currently food and drug administration-approved for use in combination with aromatase inhibitors in postmenopausal women with metastatic hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer. Palbociclib is also food and drug administration-approved for use in combination with fulvestrant in hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer progressing after endocrine therapy. Abemaciclib is the newest cyclin-dependent kinase 4/6 inhibitor to gain Food and Drug Administration (FDA) approval, specifically as monotherapy for hormone receptor-positive, human epidermal growth factor receptor 2-negative metastatic breast cancer previously treated with chemotherapy and endocrine therapy. Abemaciclib also shares a similar indication with palbociclib for use in combination with fulvestrant in hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer progressing after endocrine therapy. Trilaciclib use remains largely investigational at this time. However, despite FDA-approval for only metastatic hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer, all four cyclin-dependent kinase 4/6 inhibitors have shown promise in hematologic malignancies and non-breast solid tumors. Although further research is needed, cyclin-dependent kinase 4/6 inhibitors represent intriguing developments in the treatment of various malignancies, including those with such poor prognoses as glioblastoma multiforme, mantle cell lymphoma, and metastatic melanoma. We discuss the approved indications, current research, and areas of future exploration for palbociclib, ribociclib, abemaciclib, and trilaciclib.

Ensuring patient safety when implementing a new diagnostic pathway for thyroid nodules.

Introduction The aim of this study was to determine whether ultrasound alone is sufficient to safely exclude malignancy in thyroid nodules in a district general hospital setting, to comply with the latest British Thyroid Association guidelines. Methods This retrospective study investigated the quality of ultrasound reporting and the correlation between ultrasound report and histology for individual thyroid nodules. Cases were selected from the thyroid multidisciplinary meeting and included all patients having undergone surgery for a thyroid malignancy in a one-year period. Results Forty-seven patients were included in the study. Ultrasound reports were reviewed and assessed, in which 21 clinicians were involved; 36% of scans included a summary of whether the nodule(s) overall appeared benign, equivocal, suspicious or malignant; 4% of reports included a U classification; 81% of reports commented on cervical lymph nodes. Ultrasound was compared with histology. The sensitivity of ultrasound in correctly identifying nodules requiring further investigation was of 56% and specificity was 81%. Positive predictive value was 81% and negative predictive value was 56%. Discussion These findings suggest that, in a district general hospital setting without a dedicated head and neck radiologist, using only ultrasound and limiting fine-needle aspiration cytology to identify suspicious nodules may not be safe, as a high number of nodules appearing benign on ultrasound may ultimately prove to be malignant.

Comparison of sprinting vs non-sprinting to wean nasal continuous positive airway pressure off in very preterm infants.

OBJECTIVE: Though nasal continuous positive airway pressure (NCPAP) is commonly used for non-invasive neonatal respiratory support, the optimal method of weaning NCPAP is not established. In this prospective, two-center randomized control trial we hypothesize that gradually increasing spontaneous breathing time off NCPAP increases successful weaning from NCPAP in infants born <31 weeks gestational age. STUDY DESIGN: Infants were randomized to one of the two NCPAP weaning protocols, a sprinting, that is, gradually increasing spontaneous breathing time off CPAP, protocol vs a non-sprinting (weaning pressure down) protocol. RESULT: Eighty-six infants were enrolled in one of the two study groups. Thirty-one infants (77%) in the sprinting group and 30 (75%) in the non-sprinting group were successfully weaned off NCPAP at the first attempt (P>0.05). It took 1.3 (1 to 1.75) (median (IQR)) attempts and 7 (7 to 7) days to wean NCPAP off in the sprinting group vs 1.3 (1 to 1.75) attempts and 7 (7 to 10) days in the non-sprinting group (P>0.05). Additionally, no differences in the secondary outcomes of bronchopulmonary dysplasia, severe retinopathy of prematurity (⩾stage 3), periventricular leukomalacia and length of stay were noted between the two groups. CONCLUSION: Weaning NCPAP via sprinting or non-sprinting protocol is comparable, not only for successful weaning but also for the occurrence of common neonatal morbidities that impact the long-term outcome in premature infants (ClinicalTrials.gov number, NCT02819050).

Laparoscopic sleeve gastrectomy improves renal transplant candidacy and posttransplant outcomes in morbidly obese patients.

Morbid obesity is a barrier to kidney transplantation due to inferior outcomes, including higher rates of new-onset diabetes after transplantation (NODAT), delayed graft function (DGF), and graft failure. Laparoscopic sleeve gastrectomy (LSG) increases transplant eligibility by reducing BMI in kidney transplant candidates, but the effect of surgical weight loss on posttransplantation outcomes is unknown. Reviewing single-center medical records, we identified all patients who underwent LSG before kidney transplantation from 2011-2016 (n = 20). Post-LSG kidney recipients were compared with similar-BMI recipients who did not undergo LSG, using 2:1 direct matching for patient factors. McNemar's test and signed-rank test were used to compare groups. Among post-LSG patients, mean BMI ± standard deviation (SD) was 41.5 ± 4.4 kg/m2 at initial encounter, which decreased to 32.3 ± 2.9 kg/m2 prior to transplantation (P < .01). No complications, readmissions, or mortality occurred following LSG. After transplantation, one patient (5%) experienced DGF, and no patients experienced NODAT. Allograft and patient survival at 1-year posttransplantation was 100%. Compared with non-LSG patients, post-LSG recipients had lower rates of DGF (5% vs 20%) and renal dysfunction-related readmissions (10% vs 27.5%) (P < .05 each). Perioperative complications, allograft survival, and patient survival were similar between groups. These data suggest that morbidly obese patients with end-stage renal disease who undergo LSG to improve transplant candidacy, achieve excellent posttransplantation outcomes.

Tube Feed Necrosis after Major Gastrointestinal Oncologic Surgery: Institutional Lessons and a Review of the Literature.

BACKGROUND: Small bowel necrosis after enteral feeding through a jejunostomy tube (tube feed necrosis, TFN) is a rare, serious complication of major abdominal surgery. However, strategies to reduce the incidence and morbidity of TFN are not well established. Here, in the largest series of TFN presented to date, we report our institutional experience and a comprehensive review of the literature. METHODS: Eight patients who experienced TFN from 2000 to 2014 after major abdominal surgery for oncologic indications at the University of Cincinnati were reviewed. Characteristics of post-operative courses and outcomes were reviewed prior to and after a change in tube-feeding protocol. The existing literature addressing TFN over the last three decades was also reviewed. RESULTS: Patients with TFN ranged from 50 to 74 years old and presented with upper gastrointestinal tract malignancies amenable to surgical resection. Six and two cases of TFN occurred following pancreatectomy and esophagectomy, respectively. Prior to TF protocol changes, which included initiation at a low rate, titrating up more slowly and starting at one-half strength TF, three of six cases of TFN (50%) resulted in mortality. With the new TF protocol, there were no deaths, goal TF rate was achieved 3 days later, symptoms of TFN were recognized 3 days earlier, and re-operation was conducted 1 day earlier. CONCLUSION: This case series describes a change in clinical practice that is associated with decreased morbidity and mortality of TFN. Wider implementation and further refinement of this tube-feeding protocol may reduce TFN incidence at other institutions and in patients with other conditions requiring enteral nutrition.

Use of vital pulp therapies in primary teeth with deep caries lesions

PURPOSE: This manuscript presents evidence-based guidance on the use of vital pulp therapies for treatment of deep caries lesions in children. A guideline panel convened by the American Academy of Pediatric Dentistry formulated evidence-based recommendations on three vital pulp therapies: indirect pulp treatment (IPT; also known as indirect pulp cap), direct pulp cap (DPC), and pulpotomy. METHODS: The basis of the guideline's recommendations was evidence from "Primary Tooth Vital Pulp Therapy: A Systematic Review and Meta-Analysis." (Pediatr Dent 2017;15;39[1]:16-23.) A systematic search was conducted in PubMed®/MEDLINE, Embase®, Cochrane Central Register of Controlled Trials, and trial databases to identify randomized controlled trials and systematic reviews addressing peripheral issues of vital pulp therapies such as patient preferences of treatment and impact of cost. Quality of the evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation approach; the evidence-to-decision framework was used to formulate a recommendation. RESULTS: The panel was unable to make a recommendation on superiority of any particular type of vital pulp therapy owing to lack of studies directly comparing these interventions. The panel recommends use of mineral trioxide aggregate (MTA) and formocresol in pulpotomy treatments; these are recommendations based on moderate-quality evidence at 24 months. The panel made weak recommendations regarding choice of medicament in both IPT (moderate-quality evidence [24 months], low quality evidence [48 months]) and DPC (very-low quality evidence [24 months]). Success of both treatments was independent of type of medicament used. The panel also recommends use of ferric sulfate (low-quality evidence), lasers (low-quality evidence), sodium hypochlorite (very low-quality evidence), and tricalcium silicate (very low-quality evidence) in pulpotomies; these are weak recommendations based on low-quality evidence. The panel recommended against the use of calcium hydroxide as pulpotomy medicament in primary teeth with deep caries lesions. Conclusions and practical implications: The guideline intends to inform the clinical practices with evidence-based recommendations on vital pulp therapies in primary teeth with deep caries lesions. These recommendations are based upon the best available evidence to-date.(AU)

Evidence-based clinical practice guideline for the use of pit-and-fissure sealants: a report of the American Dental Association and the American Academy of Pediatric Dentistry

BACKGROUND: This article presents evidence-based clinical recommendations for the use of pit-and-fissure sealants on the occlusal surfaces of primary and permanent molars in children and adolescents. A guideline panel convened by the American Dental Association (ADA) Council on Scientific Affairs and the American Academy of Pediatric Dentistry conducted a systematic review and formulated recommendations to address clinical questions in relation to the efficacy, retention, and potential side effects of sealants to prevent dental caries; their efficacy compared with fluoride varnishes; and a head-to-head comparison of the different types of sealant material used to prevent caries on pits and fissures of occlusal surfaces. TYPES OF STUDIES REVIEWED: This is an update of the ADA 2008 recommendations on the use of pit-and-fissure sealants on the occlusal surfaces of primary and permanent molars. The authors conducted a systematic search in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and other sources to identify randomized controlled trials reporting on the effect of sealants (available on the US market) when applied to the occlusal surfaces of primary and permanent molars. The authors used the Grading of Recommendations Assessment, Development, and Evaluation approach to assess the quality of the evidence and to move from the evidence to the decisions. RESULTS: The guideline panel formulated 3 main recommendations. They concluded that sealants are effective in preventing and arresting pit-and-fissure occlusal carious lesions of primary and permanent molars in children and adolescents compared with the nonuse of sealants or use of fluoride varnishes. They also concluded that sealants could minimize the progression of noncavitated occlusal carious lesions (also referred to as initial lesions) that receive a sealant. Finally, based on the available limited evidence, the panel was unable to provide specific recommendations on the relative merits of 1 type of sealant material over the others. CONCLUSIONS AND PRACTICAL IMPLICATIONS: These recommendations are designed to inform practitioners during the clinical decision-making process in relation to the prevention of occlusal carious lesions in children and adolescents. Clinicians are encouraged to discuss the information in this guideline with patients or the parents of patients. The authors recommend that clinicians reorient their efforts toward increasing the use of sealants on the occlusal surfaces of primary and permanent molars in children and adolescents.(AU)

Evidence-based Update of Pediatric Dental Restorative Procedures: Preventive Strategies.

BACKGROUND: There has been significant advances in the understanding of preventive restorative procedures regarding the advantages and disadvantages for restorative procedures; the evidence for conservative techniques for deep carious lesions; the effectiveness of pit and fissure sealants; and the evidence for use of resin infiltration techniques. AIM: The intent of this review is to help practitioners use evidence to make decisions regarding preventive restorative dentistry in children and young adolescents. STUDY DESIGN: This evidence-based review appraises the literature, primarily between the years 1995-2013, on preventive restorative strategies. The evidence was graded as to strong evidence, evidence in favor, or expert opinion by consensus of authors Results: The preventive strategy for dental caries includes individualized assessment of disease progression and management with appropriate preventive and restorative therapy. There is strong evidence that restoration of teeth with incomplete caries excavation results in fewer signs and symptoms of pulpal disease than complete excavation. There is strong evidence that sealants should be placed on pit and fissure surfaces judged to be at risk for dental caries, and surfaces that already exhibit incipient, non-cavitated carious lesions. There is evidence in favor for resin infiltration to improve the clinical appearance of white spot lesions. CONCLUSIONS: Substantial evidence exists in the literature regarding the value of preventive dental restorative procedures.

Evidence-based Update of Pediatric Dental Restorative Procedures: Dental Materials.

BACKGROUND: The science of dental materials and restorative care in children and adolescent is constantly evolving, and the ongoing search for ideal restorative materials has led to plethora of research. AIM: To provide an evidence base to assist dental practitioners choose appropriate restorative care for children and adolescents. STUDY DESIGN: This evidence-based review appraises this literature, primarily between the years 1995-2013, for efficacy of dental amalgam, composites, glass ionomer cements, compomers, preformed metal crowns and anterior esthetic restorations. The assessment of evidence for each dental material was based on a strong evidence, evidence in favor, expert opinion, and evidence against by consensus of the authors. RESULTS: There is varying level of evidence for the use of restorative materials like amalgam, composites, glass ionomers, resin-modified glass-ionomers, compomers, stainless steel crowns and anterior crowns for both primary and permanent teeth. CONCLUSIONS: A substantial amount data is available on restorative materials used in pediatric dentistry; however, there exists substantial evidence from systematic reviews and randomized clinical trials and clinicians need to examine and understand the available literature evidence carefully to aid them in clinical decision making.

Working Length Determination of Root Canal of Young Permanent Tooth: An In vitro Study.

BACKGROUND: Determination of correct working length is one of the keys to success in endodontic therapy. AIM: The aim of this study was to evaluate the diagnostic efficacy of various methods to determine working length of root canal. MATERIALS AND METHODS: Tactile method was assessed using digital radiography and compared with electronic method using apex locator. A total sample of 30 single rooted young permanent teeth the (mandibular first premolars) with matured apices were selected for the study. Access cavity preparation was carried out. Working length was measured by tactile method using digital radiography and electronic method using apex locator with no 15 K file. Actual working length was established by grinding of cementum and dentine from the root apex and was observed under stereomicroscope. Data was collected and statistical analysis was carried out with the help of SPSS-15. RESULTS: The results of this study showed that there was a significant difference between tactile method assessed by digital radiography and electronic method using apex locator. CONCLUSION: Apex locator was found to be more reliable and accurate when compared with the actual length.

The use of botulinum toxin in otorhinolaryngology: an updated review.

BACKGROUND: The use of botulinum toxin in Otorhinolaryngology has rapidly expanded over the last decade. Current observation is that the use of botulinum toxin in Otorhinolaryngology is relatively poorly acknowledged by Otorhinolaryngologists. OBJECTIVE OF REVIEW: To summarise the non-cosmetic uses of botulinum toxin in Otorhinolaryngology. TYPE OF REVIEW: Narrative. SEARCH STRATEGY AND EVALUATION METHOD: A literature search was performed using the Medline and Embase databases. Combinations of 'botulinum toxin' with each indication were searched. A citation was included if it evaluated a non-cosmetic use of botulinum toxin in Otorhinolaryngology. Eligibility of studies was assessed by two reviewers. A total of 1187 abstracts were reviewed and 97 articles identified. CONCLUSIONS: Botulinum toxin provides an effective and minimally invasive treatment option in a wide range of non-cosmetic indications. Side-effects are few and transient with an excellent safety profile. Ongoing research is required to fully critically appraise its uses.

Quality of life assessment following adenotonsillectomy for obstructive sleep apnoea in children under three years of age.

AIM: To investigate the effects of adenotonsillectomy on the quality of life of children under three years of age with obstructive sleep apnoea. To our knowledge, there have been no previously published studies on this topic. METHOD: Thirty-nine children under three years of age and treated with adenotonsillectomy for obstructive sleep apnoea met the inclusion criteria. A quality of life questionnaire was adapted from the validated, six-item instrument developed by de Serres et al. (2000). The questionnaire assessed improvement in specific domains following adenotonsillectomy. Carers scored each domain on a point scale ranging from 'none' (0) to 'couldn't be more' (6). RESULTS: The quality of life of all children improved after surgery. The greatest mean improvement scores were in the domains of care-giver concern, physical suffering and sleep disturbance. The modal questionnaire score was 4 and the overall mean questionnaire score was 4.2. CONCLUSION: Adenotonsillectomy provides measurable improvements in quality of life for children under three years of age with obstructive sleep apnoea.

Transnational caregiving: Part 1, caring for family relations across nations.

This article concerns how globalization and the aging of the world's population are affecting the already complex issue of intergenerational transnational caregiving. Globalization has caused an increase in workforce mobility with large numbers of individuals seeking employment overseas. This, coupled with increased longevity globally, has resulted in many workers leaving their elderly parents in need of care in their home countries. This has spawned caregiving across national borders, or caring for family relations across nations. Currently in the United States, not enough emphasis is given to family caregiving. Data compiled by AARP and the National Alliance for Caregiving estimate the economic value for this group of family caregivers in 2007 to be $375 billion, accounting for 34-52 million family caregivers per given year. This does not include those families who are transnational caregivers. The seminal work in this emerging field has been done by social anthropologists Loretta Baldassar, Cora Velekoop Baldock, and Raelene Wilding, who have defined the components of transnational caregiving based on an ethnographic study using qualitative data to study nine immigrant communities in Western Australia. Although their research focused on caregiving from a distance, additional work has been added to the discussion by introducing the element of "care drain" and further cultural perspectives. Therefore, this research is an exploratory study on intergenerational transnational caregiving within the context of the changing world and its demographics. Within the context of globalization and global aging, the following questions are addressed: What is the significance of family caregiving? What is a transnational? How has technology changed "transnationalism" today? What are the elements that comprise transnational caregiving? How does culture play a role in transnational caregiving? What are some of the national initiatives undertaken by governments to aid in workforce issues and recognition of caregiving organizations? By exploring these questions, it is hoped that there will be a better understanding of transnational caregiving and its relevance in all societies.

Antianxiety activity of Gelsemium sempervirens.

CONTEXT: The clinical applications of well-known benzodiazepines as anxiolytic agents are limited because of their side effects. Therefore, the development of new pharmacological agents, from medicinal plants, is well justified. OBJECTIVE: Among medicinal plants, Gelsemium sempervirens (L.) Aiton. (Loganiaceae) has been recommended for relief of anxiety in traditional folk medicines. Nevertheless, no pharmacological studies have so far evaluated it in this regard. The purpose of the present study was to investigate the anxiolytic effects of various extracts of the roots and rhizomes of G. sempervirens. MATERIALS AND METHODS: Petroleum ether, chloroform, methanol, and water extracts of G. sempervirens were prepared by successive extractions using a Soxhlet apparatus, and subsequently evaluated for antianxiety activity using the elevated plus maze model. Diazepam was used as standard drug. RESULTS: Among various extracts, the methanol extract of G. sempervirens exhibited significant increases in open arm entries and mean time spent in open arms at the dosage of 150 mg/kg. A fraction (F9.4) derived from the methanol extract was also observed to exhibit significant anxiolytic activity at the dose level of 10 mg/kg in the elevated plus maze test. CONCLUSION: The present study clearly demonstrated that the methanol extract exerts an anxiolytic effect on mice, and it could serve as a new approach for the treatment of anxiety.

The genus Gelsemium: An update.

The review includes 103 references on the genus Gelsemium, and comprises ethnopharmacology, morphology, phytoconstituents, pharmacological reports, clinical studies and toxicology of the prominent species of Gelsemium. Alkaloids and iridoids constitute major classes of phytoconstituents of the genus. Most popular species of the genus are the Asian G. elegans and the two North American related species, G. sempervirens and G. rankinii. Gelsemium species are categorized under medicinal as well as poisonous plants. Amongst various species, G. elegans and G. sempervirens possess medicinal value, and have been traditionally used as nervous system relaxant. These plants have been explored exhaustively for their anticancer activity. In the concluding part, the future scope of Gelsemium species has been emphasized with a view to establish their multifarious biological activities and mode of actions.

Thyroid surgery: the sub-mental drain.

OBJECTIVE: To propose an alternative site of thyroid drain placement. BACKGROUND: During thyroid surgery, post-operative drains are often placed. It is common practice to bring out the drain lateral to the wound, often creating an additional, unsightly scar. CONCLUSION: We have found excellent cosmesis is achieved by bringing out the drain in the midline in a sub-mental skin crease, with the scar hidden in the chin shadow. In our experience, such drain placement is a safe, straightforward method with an excellent cosmetic result.
