Laparoscopic modified e-tep repair of concomitant inguinal and ventral hernias.

BACKGROUND: Laparoscopic hernia repair in recent times has gained the most acceptance among both the surgical community and the patient groups, as it has proven benefits of lesser postoperative hospital stay and less pain scores. The incidence of both inguinal and ventral hernias has increased significantly in the present days. Various methods have been postulated by different surgical groups for repairing the same but no there is no standard consensus on managing concomitant inguinal and ventral hernias. The conventional e-TEP requires an extensive dissection with increased operative time. We present our experience in managing cases with both inguinal and primary M2/M3 and W1 ventral hernias with or without divarication of recti using a modified up to down approach for inguinal hernia followed by down to up approach for the ventral hernia, from a tertiary care center in South India. MATERIALS AND METHODS: We managed 16 cases with simultaneous incidence of inguinal and primary M2/M3 and W1 ventral hernias with or without divarication of recti between January 2022 and November 2023. Institute ethical committee clearance and informed consent was obtained from all the 16 patients. They were all subjected to an extra peritoneal repair of both the hernias. All the demographic data, intraoperative data, postoperative complications and follow up were digitally stored. All patients were followed up for six months after surgery. RESULTS: Out of 16 patients, 15 were males and 1 was female. The mean age was 48 years and the mean BMI of all the patients was 29.2 kg/m2. The postoperative recovery was smooth in all patients and being discharged within 24 h after surgery. The pain scores of all patients were significantly lower than patients who underwent intraperitoneal repair. CONCLUSION: e-TEP hernia repair is gaining popularity and has amused the hernia surgical community. Our method of e-TEP RS repair in cases with concomitant inguinal and primary M2/M3 W1 ventral hernias with or without divarication helps in addressing both the hernias in the extra-peritoneal space. Our technique reduces the area of dissection needed for mesh placement and preserves the integrity of abdominal musculature in the upper abdomen when compared with the conventional technique. It further allows extension of the e-TEP inguinal space into the Rectro rectus space without much alteration in the port arrangement allowing simultaneous repair of groin and umbilical hernias. Good knowledge of anatomy and laparoscopic skills are pertinent for safe and effective hernia repair by this technique.

Injection of sodium hypochlorite into soft tissues of the oral cavity: A literature review with clinical preventive recommendations.

Injection of sodium hypochlorite (NaOCl) solution instead of local anaesthetic (LA) solution is an iatrogenic error with serious consequences including medico-legal implications. Such cases have been reported despite recommended precautionary measures. The purpose of this article is to review the literature on such cases and present clinical preventive recommendations. Electronic search was conducted in PubMed/Medline, Google Scholar, Cochrane, Scopus, Lilacs, ScienceDirect, and Crossref databases for articles reporting accidental or mistaken or inadvertent injection of NaOCl instead of LA during dental or endodontic treatment. Articles reporting NaOCl accident due to extrusion or injection of NaOCl beyond root confines were excluded. A total of 11 articles were found and reviewed. Data pertaining to the patient, injected NaOCl, cause, clinical manifestations, management, hospitalization, healing and recovery, and long-term or residual effects were extracted, compiled, and analysed for interpretation and discussion. Injection of NaOCl instead of LA into the soft tissues leads to varying clinical manifestations with unpredictable extent, outcome, and recovery period. The onus lies with the clinician to prevent it. Therefore, a clinician must take all the precautionary measures and confirm the identity of LA and NaOCl solutions before delivering them. The presented clinical recommendations assist clinicians to prevent it, including its potential medico-legal consequences. However, in case of such an unfortunate event, it is crucial to immediately identify and quickly manage it to limit the tissue damage or complications.

Analysis of Shaping Abilities of Rotary File Systems in Oval Canals with Moderate Root Curvature: A Randomized Controlled Ex Vivo Study.

AIM: The purpose of this study was to evaluate and compare the canal transportation tendencies and centering ability of the TruNatomy shaper (TN) and XP-endo shaper (XPS) rotary systems in oval-shaped canals with moderate root curvature (15°-25°), using cone-beam computed tomography (CBCT) imaging. MATERIALS AND METHODS: Sixty single-rooted permanent human teeth were chosen after considering the inclusion and exclusion criteria. The teeth were divided into two groups (n = 30). The test group was instrumented with TN files and the other with XPS according to manufacturer's instructions. CBCT images were taken before and after instrumentation to record the root canal distances from mesial, distal, buccal, and lingual borders of the root at 3, 5, and 7 mm distances from the root apex using a specific formula. Statistical analysis was done using the Statistical Package for the Social Sciences software program, version 20.0. The data were analyzed using the unpaired t test. RESULTS: Both TN and XPS were safe for use in oval-shaped canals with moderate root curvature. However, the XPS showed higher buccolingual transportation as compared with TN at 3 mm from the apex and higher mesiodistal transportation at 3 and 5 mm levels from the apex as compared with TN. CONCLUSION: Canal transportation has been detected in both systems; however, the values obtained were within the safe range (<0.3 mm). Overall, no significant difference was observed between TN and XPS (p > 0.05) in their canal transportation tendencies and centering ability. CLINICAL SIGNIFICANCE: The study assesses the canal centering and transportation tendencies of the recently launched TN rotary system in extracted teeth with a combination of morphologies. The findings of the study are significant clinically as minimum transportation of the canal, minimal dentin removal, efficient disinfection, and three-dimensional obturation of the root canal are considered important factors in deciding the prognosis of endodontic therapy.

Factors influencing the occurrence and progress of sodium hypochlorite accident: A narrative and update review.

Sodium hypochlorite (NaOCl) is one of the most commonly used irrigant because of its several advantages. However, it is highly cytotoxic and can lead to severe tissue damage. NaOCl accident occurs when it is extruded beyond root confines into periapical or periradicular tissues. It is an irrigant mishap which can be life threatening and/or cause residual or long term or permanent consequences with malpractice and medico-legal implications. There are many factors which can influence the occurrence and progress of NaOCl accident. These factors can be broadly categorized as patient (host)-, tooth-, operator-, and NaOCl-related factors. They can be further categorized as predisposing and extent factors. It is vital for a clinician to thoroughly understand and identify various influencing factors to prevent NaOCl accident with its associated consequences including any potential medico-legal issues. The purpose of this article is to provide a narrative review on various factors which predispose to the occurrence of NaOCl accident and influence its extent and/or outcome.

Advances in Mechanical Thrombectomy for Acute Ischemic Stroke Due to Large Vessel Occlusion.

Acute ischemic stroke (AIS) is a significant cause of global morbidity and mortality, with functional implications for quality of life and long-term disability. The limitations of intravenous thrombolytic therapy for the treatment of AIS, especially for emergent large vessel occlusion (ELVO), have paved the way for alternative therapies and the rapidly evolving landscape of endovascular therapy (EVT). Here, we summarize the major landmark trials that have advanced the field largely due to ongoing biomedical engineering device development that have translated into significantly improved clinical outcomes. Our review describes the clinical success of EVT, and current and future trends.

Application of a new system for classifying root canal morphology in undergraduate teaching and clinical practice: a national survey in Malaysia.

AIM: To evaluate and compare the feedback of final year undergraduate dental students in eight Malaysian dental schools on the application of a new system for classifying root canal morphology in teaching and clinical practice. METHODS: One PowerPoint presentation describing two classification systems for root canal morphology (Oral Surgery Oral Medicine Oral Pathology, 1974 38, 456 and its supplemental configurations, International Endodontic Journal 2017, 50, 761) was delivered to final year undergraduate dental students in eight dental schools in Malaysia by two presenters (each presented to four schools). To examine students' feedback on the utility of each system, printed questionnaires consisting of six questions (five multiple choice questions and one open-ended question) were distributed and collected after the lecture. The questionnaire was designed to compare the classification systems in terms of accuracy, practicability, understanding of root canal morphology and recommendation for use in pre-clinical and clinical courses. The exact test was used for statistical analysis, with the level of significance set at 0.05 (P = 0.05). RESULTS: A total of 382 (out of 447) students participated giving a response rate of 86%. More than 90% of students reported that the new system was more accurate and more practical compared with the Vertucci system (P < 0.001). Overall, 97% of students reported the new system helped their understanding of root and canal morphology compared with the Vertucci classification (P < 0.001). Over 97% of students recommended the use of the new system in teaching, pre-clinical courses and clinical practice (P < 0.001). Except for two schools, no significant difference was detected between the responses of students for all questions at the different schools (P > 0.05). The students' responses for all questions were almost similar for both presenters (P > 0.05). CONCLUSIONS: The new system of International Endodontic Journal 2017, 50, 761 for classifying root and canal morphology was favoured by final year undergraduate dental students in Malaysia. The new system has the potential to be included in the undergraduate endodontic curriculum for teaching courses related to root and canal morphology.

Major haemorrhage following vascular injury during exchange of cardiac pacemaker leads.

An 80-year-old lady suffered loss of cardiac output during an elective pacemaker lead exchange. Right ventricular perforation, cardiac tamponade, vascular lacerations and circulatory shock are known major complications of pacemaker lead exchange and may necessitate aggressive resuscitation. An emergency sternotomy revealed the administered fluid, blood products and resuscitative drugs, which were administered through an upper limb cannula, had likely extravasated at the site of an iatrogenic injury to the superior vena cava. Unfortunately, further resuscitation attempts were unsuccessful. There are no recommendations regarding sites for intravascular access during pacemaker lead exchange and we argue that lower limb veins should be considered for venous access, as the superior vena cava and innominate veins are possible sites of unintentional vascular injury.

Using a syringe needle to cut dentin and dislodge and remove a metallic obstruction from the root canal.

A metallic obstruction in the canal orifice of a maxillary right canine could not be bypassed during endodontic treatment. Aids such as ultrasonics and retrieval kits were not available for the removal of the obstruction. Therefore, a novel approach using a disposable syringe needle was employed. A 22-gauge needle was inserted into the orifice and turned in an arc with a gentle apical pressure and alternate rocking motion around the obstruction. This procedure was repeated few times to cut dentin and successfully dislodge and remove the obstruction using the sharp beveled tip of the needle. This case report demonstrates that, in the absence of other aids, the use of a disposable syringe needle is a simple, economical, and yet an effective technique for conservative removal of dentin and to dislodge and remove an obstruction from the root canal. However, its effectiveness depends on case selection and straight-line accessibility to the obstruction.

Performance of Redox Active and Chelatable Iron Assays to Determine Labile Iron Release From Intravenous Iron Formulations.

Emerging data from global markets outside the United States, where many generic iron sucrose formulations are available, have revealed that non-US generic intravenous (i.v.) iron formulations may have iron release profiles that differ from the reference listed drug (RLD). The first generic i.v. iron approved in the United States was sodium ferric gluconate complex in 2011. We evaluated chelatable and redox labile iron assay methods to measure the amount of labile iron released from i.v. iron formulations in biorelevant matrices in vitro. The majority of published labile iron assays evaluated were not suitable for use in vitro due to overwhelming interference by the presence of the i.v. iron products. However, an optimized high-performance liquid chromatography (HPLC)-based method performed well for use in vitro labile iron detection in a biorelevant matrix. Application of this method may enhance bioequivalence evaluation of generic i.v. iron formulations in the future.

Transverse incision transvaginal rectocele repair combined with levatorplasty and biological graft insertion: technical details and case series outcomes.

BACKGROUND: The purpose of this report is twofold: first, to detail our operative approach to rectocele repair, and second, to report on the outcomes. METHODS: Transverse incision transvaginal rectocele repair combined with levatorplasty and biological graft placement is detailed using hand-drawn sketches and intraoperative photographs. All patients with symptoms of functional constipation and non-emptying rectocele operated on from May 2007 to March 2013 at our institution were enrolled in this study. Data from a prospectively maintained database were retrospectively analyzed. Preoperative and postoperative functional outcomes were studied using a validated 31-point obstructed defecation (OD) scoring system. Follow-up was 1 year. RESULTS: Twenty-three patients underwent the procedure. The mean age of patients was 55 years (range 28-79 years). The OD severity score improved from the preoperative mean of 21.6 to postoperative mean of 5.5 (p = 0.001). Three out of four patients with initial symptoms of dyspareunia (75%) reported significant improvement in dyspareunia, while 2 out of 19 patients without initial symptoms of dyspareunia (11%) reported mild dyspareunia following the repair. One patient (4%) required operative drainage of a hematoma. Another patient (4%) developed symptomatic recurrence which was confirmed radiologically. CONCLUSIONS: In properly selected patients, the technique described leads to significant improvement in symptoms of OD and low recurrence without an increased rate of dyspareunia.

Comparative evaluation of the calcium release from mineral trioxide aggregate and its mixture with glass ionomer cement in different proportions and time intervals - An in vitro study.

BACKGROUND: Addition of glass ionomer cement (GIC) has been suggested to improve the setting time and handling characteristics of mineral trioxide aggregate (MTA). This study evaluated the effect of adding GIC to MTA in terms of calcium release, an issue that has not been previously studied. MATERIALS AND METHODS: The study comprised four groups with five samples each: a control group of MTA alone and experimental groups I (1MTA:1GIC), II (2MTA:1GIC), and III (1MTA:2GIC) based on the mixture of MTA and GIC powders in the respective proportions by volume. Calcium release from the samples was measured by atomic absorption spectrophotometry at 15 min, 6 h, 24 h, and 1 week after setting. The level of statistical significance was set at p < 0.05. RESULTS: Groups I (1MTA:1GIC) and III (1MTA:2GIC) released significantly less calcium than the control group at all time periods, except at 15 min for group I. Group II (2MTA:1GIC) showed no significant difference in calcium release compared to the control at any time period. Group II exhibited greater calcium release than group I or III at all time periods, with significant differences between groups I and II at 1 week and between groups I and III at 24 h and 1 week. There were no statistical differences in calcium release between groups I and III. CONCLUSIONS: Adding GIC to improve the setting time and handling properties of the MTA powder can be detrimental to the calcium-releasing ability of the resultant mixture, depending on the proportion of GIC added. Adding MTA and GIC at a proportion of 2:1 by volume did not impact calcium release from the mixture. These findings should be verified through further clinical studies.

Medication-related dental erosion: a review.

Dental erosion has become a major problem that affects the long-term health of the dentition. Among the various potential causes for erosive tooth wear, the different drugs prescribed for patients may be overlooked. Several therapeutic medications can directly or indirectly be associated with dental erosion. It is the responsibility of oral health providers to make both patients and colleagues aware of drugs that may contribute to this condition. Therefore, the purpose of this discussion is to provide an overview of the various therapeutic medications that can be related to tooth erosion. The authors also include precautionary measures-summarized as The 9 Rs-to avoid or at least reduce medication-induced erosion.

The impact of effective paediatric adherence promotion interventions: systematic review and meta-analysis.

BACKGROUND: Understanding the impact of effective paediatric adherence promotion interventions on patients, families and the healthcare system is necessary to inform efforts to improve healthcare quality and control costs. Building on previous research suggesting that improving adherence may have far-reaching benefits, the objective of this study was to quantify the impact of effective adherence promotion interventions for children and adolescents with a chronic medical condition on patients, families and the healthcare system. METHODS: Authors systematically reviewed articles indexed in PubMed, PsycINFO and CINAHL to identify randomized controlled trials of paediatric adherence promotion interventions. Interventions that improved paediatric adherence and examined patient-level, family-level or healthcare system-level outcomes in children and adolescents (M age ≤ 18 years) with a chronic medical condition were included. Two authors independently extracted and classified outcome variables as patient-level (quality of life and disease-related activity restrictions), micro-level (family functioning, family conflict, caregiver quality of life, caregiver sleep interruption, caregiver days away from work and patient missed school days) or macro-level variables (emergency department visits, hospitalizations, outpatient visits and urgent care visits). Outcome variables detailed in previously published reviews (i.e. disease severity) were excluded. RESULTS: Twenty studies representing 19 unique samples met inclusion criteria. An additional eight articles representing trials that did not significantly improve adherence were included in post hoc analyses. Compared with control interventions, effective paediatric adherence promotion interventions improved patient quality of life and family-level outcomes and decreased healthcare utilization among children and adolescents with a chronic medical condition. CONCLUSIONS: Interdisciplinary efforts to improve healthcare quality and reduce spending among children and adolescents with a chronic medical condition may be enhanced by incorporating effective paediatric adherence promotion interventions. As relatively few chronic medical conditions were represented in included studies, future research should examine the impact of paediatric adherence promotion interventions in other populations.
