Pediatric Epistaxis-Effectiveness of Conservative Management.

OBJECTIVES: Epistaxis is an emergency medical condition that sometimes requires admission to the emergency department. Pediatric epistaxis differs from epistaxis in the older population in terms of etiology, severity, and management. Our objective was to identify the distinctive features of pediatric epistaxis and determine the appropriate management. METHODS: This was a retrospective study of 231 medical records of children (<18 years old) with epistaxis of a total of 1171 cases in the general population who presented to our medical center's emergency department between 2013 and 2018. RESULTS: Among 231 admissions, 10 children (4.3%) presented more than once. Male patients accounted for the majority of cases (64.5%), and the average age was 9.4 years. Two children were treated with aspirin because of cardiac valve disease. Anterior bleeding was detected in 101 cases (43.7%), whereas posterior origin was observed in 8 cases (3.5%). In 122 cases (52.8%), there was no active bleeding observed. Nose injury was the cause of epistaxis in 24 cases (10.4%), and 16 admissions (6.9%) followed nasal surgical interventions. Nineteen children (8%) had abnormal coagulation tests, and 7 patients (3%) received blood transfusions. Chemical cauterization was performed in 89 cases (39.3%), and anterior packing was needed in only 9 cases (3.9%). Nine children required hospitalization (3.9%), and 2 needed surgical intervention to control bleeding. Compared with the adult population, there were significantly fewer cases of active bleeding, recurrent epistaxis, anterior packing, or need for hospitalization in the pediatric population. CONCLUSIONS: Epistaxis is significantly less severe in the pediatric population, with only a few cases requiring major intervention. Endoscopic examination of the entire nasal cavity and routine coagulation tests are not mandatory unless there is a history of recurrent epistaxis, known coagulopathy, antiplatelet/anticoagulation therapy, or a suspicion of juvenile idiopathic angiofibroma. We suggest using absorbable packs, which offer advantages over cauterization or nonabsorbable packs.

Endoscopic Chemocauterization with Trichloroacetic Acid for Congenital or Recurrent Tracheoesophageal Fistula in Children with Esophageal Atresia: Experience from a Tertiary Center.

BACKGROUND: Recurrent tracheoesophageal fistula (rTEF) is a well-known complication after surgery of EA, occurring in roughly 3-10% of the patients. Recent studies have highlighted safety and efficacy of endoscopic management of recurrent TEF. The aim of this study was to evaluate the efficacy of chemocauterization with trichloroacetic acid (TCA) in rTEF and congenital tracheoesophageal fistula (cTEF). METHODS: Retrospective chart review of consecutive patients with recurrent or congenital TEF who underwent endoscopic chemo-cauterization between 2018 and 2022 at a tertiary center. Children diagnosed with TEF who underwent primary or secondary endoscopic treatment were included. Median follow up time was 19 months for rTEF and 33 months for cTEF. RESULTS: During the study period, 18 patients were treated endoscopically by chemocatuerization with TCA at our institution. Treatment of recurrent TEF was successful in 13 of 14 patients (93%) Treatment of congenital TEF was successful in 2 of 4 patients (50%). In 14 patients, closure was seen after 1-2 treatments. There were no serious adverse reactions or complications to the endoscopic treatment of TEF. CONCLUSION: Endoscopic chemocauterization is a minimal invasive technique with low morbidity and high success rate and may be considered as primary treatment for recurrent TEF. LEVEL OF EVIDENCE: III.

Comparing recurrence between cautery techniques in pediatric epistaxis.

OBJECTIVE: To compare the risk of recurrent epistaxis between children treated with silver nitrate (SN) in the office or electrocautery (EC) in the operating room (OR). METHODS: Patients aged 2-18 diagnosed with epistaxis (ICD R04.0) in 2018 and treated with SN or EC were retrospectively reviewed. Epistaxis laterality, history of nasal trauma, and personal or family history of a bleeding disorder were recorded. Patients with prior cautery or epistaxis secondary to a procedure were excluded. Recurrence was defined as initial encounter after cautery with documented epistaxis. Patients were followed up into 2022 to track onset of recurrence. Time to recurrence between SN and EC was compared with hazard curves with predictors for recurrence analyzed via Cox's proportional hazard regression. RESULTS: Among 291 patients cauterized for epistaxis, 62 % (n = 181) received SN compared to 38 % (n = 110) who underwent EC. There was significantly higher risk of recurrence when treated with SN compared to EC (Hazard ratio 2.45, 95 % CI: 1.57-3.82, P < 0.0001). Median time to recurrence was not statistically different between techniques (6.39 months (SN) (IQR: 2.33, 14.82) vs. 4.11 months (EC) (IQR: 1.18, 20.86), P = 0.4154). Complication rates were low for both groups (1.16 % (SN) vs. 0 % (EC), P > 0.05). CONCLUSION: Among patients with epistaxis, risk of recurrence is significantly higher in those cauterized with SN compared to EC. Time to recurrence is not significantly different between cautery techniques.

Morbidity and etiology-based success rate of combined endoscopic ventriculostomy and choroid plexus cauterization: a systematic review and meta-analysis of 1918 infants.

Approaches to the treatment of infant hydrocephalus vary among centers. Standard shunting carries a significant infection rate, an unpredictable time-to-failure, and the life-long risk of recurrent failures. Combined choroid plexus cauterization (CPC) and endoscopic third ventriculostomy (ETV) have been increasingly employed over the past decade as an alternative approach in an attempt to avoid shunt dependency. We performed a systematic review and meta-analysis to explore the reported morbidity associated with ETV/CPC and its rate of success reported for specific etiologies of infant hydrocephalus. The protocol of this study was registered with the International prospective register of Systematic Reviews (PROSPERO) with the following registration number: CRD 42022343898. The study utilized four databases of medical literature to perform a systematic search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Several parameters were extracted from the included studies including authors, publication year, region, study design, sample size, mean age, success rate, complication rate, reported complications, hydrocephalus etiology, median time-to-failure, secondary management after failure, and mean follow-up time. The outcomes of interest, success, and complication rates were pooled using 95% confidence intervals (CI) and a random effects model. Heterogeneity was assessed using the I2 test. Twenty-eight studies met the inclusion criteria from an initial search result of 472 studies. The study included 1938 infants (1918 of which were included in the meta-analysis). The overall success rate of combined ETV/CPC is 0.59 (95% CI (0.53, 0.64), I2 = 82%). Etiology-based success rate is 0.71, 0.70, 0.64, and 0.52 for aqueductal stenosis, myelomeningocele, postinfectious hydrocephalus, and posthemorrhagic hydrocephalus, respectively. The overall complication rate is 0.04 (95% CI (0.02, 0.05), I2 = 14%). Our study presents a comprehensive analysis of the current evidence on the use of ETV/CPC for treating hydrocephalus in infants. The findings demonstrate the potential efficacy of this procedure; however, it is crucial to acknowledge the limitations inherent in the included studies, such as selection bias and limited follow-up, which could have impacted the reported outcomes.

Endoscopic Sphenopalatine Artery Cauterization in the Management of Recurrent Posterior Epistaxis.

Background and Objectives: Endoscopic sphenopalatine artery cauterization (ESPAC) has become a reliable and effective surgical procedure for managing posterior epistaxis. The objectives of our study were to evaluate the effectiveness of ESPAC in the management of posterior epistaxis and the possible factors that lead to the failure of the procedure. Materials and Methods: We performed a retrospective analysis of all patients who underwent ESPAC between 2018 and 2022. We retrospectively reviewed the demographic data, patients' co-morbidities, medical treatment conditions, whether other surgical procedures were performed in addition to the ESPAC, and the success rate of ESPAC. Results: 28 patients were included in our study. After ESPAC, epistaxis was successfully managed in 25 patients (89.28%). Of all patients undergoing ESPAC, three (10.7%) presented re-bleeding. In two patients, we performed an endoscopic revision surgery with re-cauterization of the sphenopalatine foramen area, together with anterior and posterior ethmoidectomy, followed by fat occlusion/obliteration of these sinuses. In one patient, fat obliteration of the anterior and posterior ethmoid was also unsuccessful, and we performed an external carotid artery ligation at the level of the neck with no recurrence afterwards. Conclusions: Endoscopic cauterization of the sphenopalatine artery remains a safe, effective, and reliable surgical procedure in the management of recurrent posterior epistaxis. The use of anticoagulant drugs and the association of hypertension and other heart and liver diseases do not materialize as factors influencing surgical failure.

Risk of post-vasectomy infections in 133,044 vasectomies from four international vasectomy practices.

OBJECTIVES: To estimate the risk of post-vasectomy infections in various settings and across various surgical techniques and sanitization practices. PATIENTS AND METHODS: Retrospective review of the records of 133,044 vasectomized patients from four large practices/network of practices using the no-scalpel vasectomy (NSV) technique in Canada (2011-2021), Colombia (2015-2020), New Zealand (2018-2021), and the United Kingdom (2006-2019). We defined infection as any mention in medical records of any antibiotics prescribed for a genital or urinary condition following vasectomy. RESULTS: Post-vasectomy infection risks were 0.8% (219 infections/26,809 procedures), 2.1% (390/18,490), 1.0% (100/10,506), and 1.3% (1,007/77,239) in Canada, Colombia, New Zealand, and the UK, respectively. Audit period comparison suggests a limited effect on the risk of infection of excising a short vas segment, applying topical antibiotic on scrotal opening, wearing a surgical mask in Canada, type of skin disinfectant, and use of non-sterile gloves in New Zealand. Risk of infection was lower in Colombia when mucosal cautery and fascial interposition [FI] were used for vas occlusion compared to ligation, excision, and FI (0.9% vs. 2.1%, p<0.00001). Low level of infection certainty in 56% to 60% of patients who received antibiotics indicates that the true risk might be overestimated. Lack of information in medical records and patients not consulting their vasectomy providers might have led to underestimation of the risk. CONCLUSION: Risk of infection after vasectomy is low, about 1%, among international high-volume vasectomy practices performing NSV and various occlusion techniques. Apart from vasectomy occlusion technique, no other factor modified the risk of post-vasectomy infection.

Comparison of the Efficacy of Combined Silver Nitrate Coagulation and Shave Excision With Surgical Excision and Linear Closure in the Treatment of Pyogenic Granuloma.

BACKGROUND: Pyogenic granuloma (PG) is a common benign vascular neoplasia. Optimal treatment should have an aesthetically pleasant scar and a low recurrence rate. No treatment method that is fully effective in solving these has been demonstrated. Silver nitrate cauterization is another method for the management of PG lesions. OBJECTIVE: The effects of silver nitrate on the treatment of PG have not been sufficiently investigated and should be investigated with objective data and a controlled study. METHODS: The prospective clinical trial was designed to compare silver nitrate cauterization with surgical excision treatment. Procedure times and procedure costs, comfort and satisfaction scales, recurrences, the Patient and Observer Scar Assessment Score, and the Vancouver Scar Scale were compared to evaluate treatments. RESULTS: Silver nitrate treatment had lower procedure times, costs, and better satisfaction and comfort scale scores. The scar assessment scores were better for the silver nitrate treatment. The patients in both groups were successfully treated and no recurrence was seen. CONCLUSION: Silver nitrate cauterization is low-cost, fast, safe, reliable, and effective with good aesthetic results for the treatment of PG lesions. This study shows that silver nitrate cauterization is a good alternative to surgical excision in the management of PG.

Preliminary Experience Suggests the Addition of Choroid Plexus Cauterization to Functional Hemispherectomy May Reduce Posthemispherectomy Hydrocephalus.

BACKGROUND: Cerebral hemispherectomy can effectively treat unihemispheric epilepsy. However, posthemispherectomy hydrocephalus (PHH), a serious life-long complication, remains prevalent, requiring careful considerations in technique selection and postoperative management. In 2016, we began incorporating open choroid plexus cauterization (CPC) into our institution's hemispherectomy procedure in an attempt to prevent PHH. OBJECTIVE: To determine whether routine CPC prevented PHH without exacerbating hemispherectomy efficacy or safety. METHODS: A retrospective review of consecutive patients who underwent hemispherectomy for intractable epilepsy between 2011 and 2021 was performed. Multivariate logistic regression was used to identify factors independently associated with PHH requiring cerebrospinal fluid (CSF) shunting. RESULTS: Sixty-eight patients were included in this study, of whom 26 (38.2%) underwent CPC. Fewer patients required CSF shunting in the CPC group (7.7% vs 28.7%, P = .033) and no patients who underwent de novo hemispherectomy with CPC developed PHH. Both cohorts experienced seizure freedom (65.4% vs 59.5%, P = .634) and postoperative complications, including infection (3.8% vs 2.4%, P = .728), hemorrhage (0.0% vs 2.4%, P = .428), and revision hemispherectomy (19.2% vs 14.3%, P = .591) at similar rates. Patients without CPC had greater odds of developing PHH requiring CSF shunting (odds ratio = 8.36, P = .026). The number needed to treat with CPC to prevent an additional case of PHH was 4.8, suggesting high effectiveness. CONCLUSION: Preventing PHH is critical. Our early experience demonstrated that routinely incorporating CPC into hemispherectomy effectively prevents PHH without causing additional complications, especially in first-time hemispherectomies. A multicenter randomized controlled trial with long-term follow-up is required to corroborate the findings of our single-institutional case series and determine whether greater adoption of this technique is justified.

Cholecalciferol-load films for the treatment of nasal burns caused by cauterization of the hypertrophied inferior turbinate: formulation, in vivo study, and clinical assessment.

Nasal turbinate hypertrophy is among the most common nasal obstruction disorders, affecting the patient's quality of life significantly. Endoscopic submucosal diathermy is a prevalent cauterization procedure for treating turbinate hypertrophy. Regrettably, the nasal burn associated with diathermy typically heals slowly causing facial pain and nasal bleeding and possibly resulting in synechiae formation. In the current study, we have developed, for the first time, a polymeric film loaded with cholecalciferol for local treatment of nasal burns. The casting method was used to prepare films of different compositions of polymers such as chitosan, polyvinyl alcohol (PVA), Carbopol 971p (CP971p), and hydroxypropyl methylcellulose (HPMC) as well as a plasticizer. Several characterizations were performed for the cholecalciferol-loaded films (e.g. weight, thickness, content uniformity, surface pH, folding endurance, disintegration time, and in vitro release) to select the optimal formulation. The optimal formulation (F4) displayed compatibility between the used polymers and the drug. In vivo animal study was carried out to assess the healing efficacy of the formulated cholecalciferol-loaded film. The rabbits treated with the cholecalciferol-loaded film demonstrated significantly higher mRNA expression of the growth factor TGF-ß and significantly lower mRNA expression of the proinflammatory cytokine TNF-α and IL-1ß compared to the plain film treated group and the untreated control group. A randomized, single-blinded, parallel, controlled clinical trial was conducted on 20 patients scheduled to undergo endoscopic submucous diathermy. The results of the clinical study demonstrated significant reductions in facial pain and nasal bleeding scores for the nostrils treated with cholecalciferol-loaded films in comparison to the nostrils treated with plain films. Furthermore, the endoscopic examination showed good healing for 95% of the cholecalciferol-loaded film-treated nostrils. In conclusion, the optimized film can be considered an opportune approach for enhancing the healing rate of nasal burns and thus reducing the downsides of the diathermy procedure.

Matrix Cauterization With Silver Nitrate in the Treatment of Ingrown Toenails in Children: Pilot Study. / [Artículo traducido] Cauterización de la matriz con nitrato de plata para el tratamiento de las uñas encarnadas en los dedos de los pies en niños: estudio piloto.

BACKGROUND: Although partial onychectomy with chemical matricectomy has been described asthe treatment of choice, there is sparse evidence in the literature regarding the use of silvernitrate for matricectomy. Our aim is to describe the effectiveness of silver nitrate for matrixcauterization after partial onychectomy. METHODS: A prospective observational study was performed on patients with ingrown toenailsstage 2-3 who underwent partial onychectomy with silver nitrate chemical matricectomy during 2018-2019 in our institution. All patients were evaluated in the outpatient clinic on the 7th and 30th post-operative day and a telephone evaluation was performed every 6 months afterthe surgical procedure to date. RESULTS: One hundred and twenty-three patients, who underwent 231 partial onychectomies with silver nitrate chemical matricectomy were included, with a median follow-up of 21 months (interquartile range, 12-29). The procedure had an effectiveness of 95.3%, with only 11 recur-rences (4.7%) reported so far on follow-up. Postoperative infections were observed in 4 patients (1.7%). Adverse effects, such as pain and postoperative drainage, were irrelevant in mostpatients. CONCLUSIONS: Silver nitrate matricectomy after partial onychectomy is an effective and safealternative for the treatment of ingrown toenail in children, with scarce postoperative morbidityand low recurrence rate.

Impact of intraventricular hemorrhage symmetry on endoscopic third ventriculostomy with choroid plexus cauterization for posthemorrhagic hydrocephalus: an institutional experience of 50 cases.

OBJECTIVE: The success rate of endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC) in the management of posthemorrhagic hydrocephalus (PHH) following intraventricular hemorrhage (IVH) in infants is not well defined. Furthermore, parameters of IVH at initial presentation have not been tested for predictive associations of ETV/CPC success in this setting. The authors sought to summarize their institutional outcomes to identify possible predictors of ETV/CPC success within this niche. METHODS: A retrospective review was conducted of all ETV/CPC procedures performed at the authors' institution for PHH between 2011 and 2021. Patients were screened against a set of selection criteria including follow-up time of at least 6 months. Associations with ETV/CPC failure were evaluated using regression and Kaplan-Meier analyses. RESULTS: A total of 50 patients satisfied all criteria. There were 32 (64%) male and 18 (36%) female patients with a mean gestational birth age of 26 weeks. The presenting IVH was symmetric in 30 (60%) and asymmetric in 20 (40%) patients, and the maximum IVH grade was IV in 30 (60%) patients overall. Six months after the procedure, ETV/CPC success was seen in 18 (36%) patients and failure in 32 (64%) patients. The median overall follow-up was 42 months, at which point ETV/CPC success was observed in 11 (22%) patients and ETV/CPC failure in 39 (78%) patients. Regression analyses indicated that radiological IVH symmetry was a statistically significant predictor of ETV/CPC failure at 6 months (OR 3.46, p = 0.04) and overall (OR 5.33, p = 0.03). Overall rates of failure were 89% versus 62% (p = 0.02) when comparing symmetric versus asymmetric IVH patients, and time to failure occurred at median times of 1.4 versus 6.5 months (p = 0.03) after the initial procedure. Higher maximum IVH grade and younger age at initial ETV/CPC only trended toward increased failure rates. When the etiology component of the ETV Success Score was adjusted such that symmetric IVH was scored 0, the area under the curve for failure at 6 months increased from 0.58 to 0.69. CONCLUSIONS: Overall, approximately 1 in 5 infants with PHH can expect to not require further intervention following ETV/CPC. The authors demonstrate that IVH symmetry is statistically predictive of ETV/CPC failure in this setting independent of all other parameters, where PHH infants with symmetric IVH are more likely to experience failure, and sooner, than PHH infants with asymmetric IVH. When discussing possible success rates of ETV/CPC for PHH, IVH symmetry should be considered.

Matrix Cauterization With Silver Nitrate in the Treatment of Ingrown Toenails in Children: Pilot Study.

BACKGROUND: Although partial onychectomy with chemical matricectomy has been described as the treatment of choice, there is sparse evidence in the literature regarding the use of silver nitrate for matricectomy. Our aim is to describe the effectiveness of silver nitrate for matrix cauterization after partial onychectomy. METHODS: A prospective observational study was performed on patients with ingrown toenails stage 2-3 who underwent partial onychectomy with silver nitrate chemical matricectomy during 2018-2019 in our institution.

Adverse effects, such as pain and postoperative drainage, were irrelevant in most patients. CONCLUSIONS: Silver nitrate matricectomy after partial onychectomy is an effective and safe alternative for the treatment of ingrown toenail in children, with scarce postoperative morbidity and low recurrence rate.

Is the Choroid Plexus Needed?

BACKGROUND: Choroid plexectomy was first performed around 1910. Later, the technique evolved into subtotal choroid plexus cauterization (CPC) but was largely abandoned following the invention of the ventriculoperitoneal shunt. Over time, with improved understanding of the pathophysiology of hydrocephalus and improvement in endoscopic techniques and equipment, the procedure of CPC was reintroduced. However, little is known about the biomolecular consequences of ablation of a significant portion of the choroid plexus on metabolic brain homeostasis, neurogenesis, and neuroimmunology. SUMMARY: The physiological functions of choroid plexus in neurogenesis and neuroimmunology and its role in diseases, such as AD and MS, should alert to possible as yet to be determined consequences. Studies, both in children and in adults, are needed not only on the success in hydrodynamic stabilization of hydrocephalus but also on the long-term outcome, especially premature neurodegeneration and inflammatory changes and on compensatory metabolic mechanisms. KEY MESSAGES: The value of CPC for treatment of hydrocephalus in medically underserved areas should be remembered, yet when alternative treatment options are available, we cannot responsibly advocate against or for the use of CPC. Therefore, perhaps a more detailed discussion of risks and benefits of a CPC with parents would be best to include the possible implications in brain development and function.

Diagnosis and Surgical Management of Neonatal Hydrocephalus.

Neonatal hydrocephalus represents an important pathological condition with significant impact on medical care and neurocognitive development. This condition requires early recognition, appropriate medical and surgical management, and long-term surveillance by clinicians and pediatric neurosurgeons. Common etiologies of neonatal and infant hydrocephalus include intraventricular hemorrhage related to prematurity with subsequent post-hemorrhagic hydrocephalus, myelomeningocele, and obstructive hydrocephalus due to aqueductal stenosis. Clinical markers of elevated intracranial pressure include rapid increases in head circumference across percentiles, elevation and firmness of the anterior fontanelle, splitting or splaying of cranial sutures, upgaze palsy, lethargy, frequent emesis, or episodic bradycardia (unrelated to other comorbidities). Complementing these clinical markers, imaging modalities used for the diagnosis of neonatal hydrocephalus include head ultrasonography, brain magnetic resonance imaging, and head computed tomography in urgent or emergent situations. Following diagnosis, temporizing measures may be employed prior to definitive treatment and include ventricular access device or ventriculo-subgaleal shunt insertion. Definitive surgical management involves permanent cerebrospinal fluid (CSF) diversion via CSF shunt insertion, or endoscopic third ventriculostomy with or without choroid plexus cauterization. Surgical decision-making and approaches vary based on patient age, hydrocephalus etiology, neuroanatomy, imaging findings, and medical comorbidities. Indications, surgical techniques, and clinical outcomes of these procedures continue to evolve and elicit significant attention in the research environment. In this review we describe the epidemiology, pathophysiology, clinical markers, imaging findings, early management, definitive surgical management, and clinical outcomes of pediatric patients with neonatal hydrocephalus.

Therapeutic outcomes of one-minute application of sodium hydroxide versus phenol in the chemical cauterization of ingrown toenails.

BACKGROUND: Ingrown nails are frequently encountered in dermatology practice. The recurrence tendency of the disorder makes chemical cauterization essential during surgical procedures. In studies comparing nail matrix cauterization with sodium hydroxide (NaOH) versus phenol, phenol's application time was highly variable. OBJECTIVE: To compare the therapeutic outcomes of matrix cauterization for a standard duration of one minute for NaOH versus phenol in stage II and III ingrown nails. MATERIAL AND METHODS: The medical records of patients undergoing matrix cauterization with 10% NaOH or 88% phenol were evaluated. The primary outcome measure was the lack of recurrences on long-term follow-up. The secondary outcome measures were complete healing duration, patient-reported pain scores, and adverse effects related to the procedure. RESULTS: Enrolled in this study were 62 ingrown toenail sides treated with 10% NaOH and 56 ingrown toenail sides treated with 88% phenol. The mean follow-up duration was 25.17 months. Recurrence was observed in four nail sides of the NaOH group (%6.45) and three nail sides of the phenol group (%5.35). The difference between the recurrence rates did not reach statistical significance. Patients treated with both methods were free of pain on the post-procedural tenth day. The visual analog scale pain scores and complete healing duration were similar between the two groups (p>0.05). CONCLUSION: In a large group with long-term follow-up results, the short-term and long-term post-operative treatment outcomes were similar between the one-minute applications of 10% NaOH versus 88% phenol groups.

Suture Ligation of Pyriform Sinus Fistulas Following Cauterization to Treat Branchial Cleft Anomalies.

OBJECTIVES: Obliteration with cauterization of the internal opening of pyriform sinus fistulas, with or without marsupialization, has been a mainstay for preventing recurrence. However, this procedure predisposes patients to recurrence caused by the reopening of the cauterized orifice. We applied suture ligation to secure the closure of the internal orifice following cauterization and evaluated treatment. METHODS: A total of 42 patients were diagnosed with third or fourth branchial cleft anomaly with internal pyriform sinus fistula and treated either with cauterization or with cauterization and suture ligation, between January 2008 and December 2020. The medical records were reviewed to assess demographic characteristics, clinical presentations, diagnoses, surgical treatment, and outcomes. Treatment flow characteristics for intractable patients were analyzed. RESULTS: The median age of onset was 9 years (range, 0-57 years). Neck swelling (n = 32, 76.2%) was commonly encountered symptom, and a history of neck infection was found in 27 patients (64.3%). After initial treatment, 11 cases (56.2%) recurred. Younger age (≤9 years) and thyroid involvement were associated with recurrence (P = .034 and P = .046, respectively). Cauterization with suture ligation presented lower recurrence rate (19.2%) than cauterization only (37.5%, P = .037). Cauterization with suture ligation for recurrent cases (n = 11) showed 81.8% (9/11) of cure rate. Intractable fistulas (n = 2) from both groups were also salvaged by suture ligation. CONCLUSIONS: Suture ligation with cauterization for an internal orifice of branchial anomaly showed lower recurrence rate than cauterization only. This method was beneficial for refractory cases.

Piriform fossa sinus tract - a 15-year retrospective review with a focus on atypical neonatal presentations.

BACKGROUND: Third and fourth branchial anomalies are rare, accounting for less than 10% of all branchial anomalies. The piriform fossa sinus tract (PFST) typically presents with left-side suppurative thyroiditis, although it can present earlier in neonates as a non-inflamed cystic neck mass. PFST poses a considerable diagnostic challenge with variable clinical and imaging features, leading to long delays to definitive diagnosis and appropriate management. OBJECTIVE: To analyse the patterns of presentation and imaging findings in children with PFST, with a particular focus on neonatal presentation. MATERIALS AND METHODS: This was a retrospective review of the clinical presentation, imaging findings and management in 16 cases of PFST presenting to our tertiary children's hospital between 2003 and 2018. Cases were identified by medical records and picture archiving and communication system (PACS) search using relevant International Classification of Diseases (ICD)-10 coding. RESULTS: Age at presentation ranged from prenatal to 16 years, with a male-to-female ratio of 2:1. All patients presented with neck swelling. Thirteen patients (81%) had suppurative thyroiditis at initial presentation. Two patients had severe thyroiditis/mediastinitis that required intensive care unit admission. Three neonates presented with noninfected, asymptomatic large cystic neck masses; two of these were detected prenatally and misdiagnosed as lymphatic malformations with subsequent spontaneous clinical resolution that later represented with evidence of PFST. The PFST was on the left side in 15/16 (94%) patients. All patients had neck imaging before definitive diagnosis. Imaging studies included radiographs, ultrasound, computed tomography, magnetic resonance imaging and barium esophagram studies. No single modality was diagnostic of PFST in all patients. Seventy-five percent of patients had multimodal imaging before diagnosis. All PFSTs were confirmed by endoscopic visualisation. Management of PFST was by endoscopic cauterisation in 13 patients and open surgery in 2. One patient did not require surgical correction. CONCLUSION: Our study highlights the complex nature of PFST. The anomaly is uncommon, has variable clinical and imaging features and may have a lengthy, complicated course if not considered at initial presentation. An episode of suppurative thyroiditis in a child should prompt investigation for PFST. We describe atypical presentations with cystic masses in neonates that appear to resolve but represent later as typical clinical features of PFST.

Choroid plexus cauterization to treat inadequate abdominal cerebrospinal fluid absorption: case report.

INTRODUCTION: Inadequate absorption of cerebrospinal fluid (CSF) in the setting of high CSF production is a relatively rare cause of shunt malfunction. CASE REPORT: We present the unique case of a 3-year-old boy who developed sterile ascites and abdominal distension in a delayed fashion after shunt placement. The shunt was externalized, and the patient was noted to have high CSF output. Bilateral choroid plexus cauterization resulted in a significant decrease in CSF production and enabled the shunt to be re-inserted into the abdomen.

Alternative sources of cautery may improve post-operative hematoma rates but increase operative time in thyroid surgery.

A retrospective risk-adjusted analysis was completed using data from the National Surgical Quality Improvement Program (NSQIP) to (1) compare the risks of post-operative hematoma for thyroid surgery using conventional cautery compared alternative energy devices (defined as LigaSure and Harmonic Scalpel), and (2) compare operative times for the same. The primary outcome variable was post-operative hematoma occurrence. The secondary outcome variable was operative time. The exposure variable was use of conventional or alternative sources of cautery. All adult patients who underwent a total thyroidectomy, subtotal thyroidectomy or completion thyroidectomy between 2016 and 2018 were included. Multivariable linear and logistic regression analyses were performed to control for potentially confounding variables. A total of 13,330 cases were analyzed; 4342 used conventional cautery, and 8988 used alternative sources. There was a statistically significant decrease in post-operative hematoma risk using alternative sources of cautery compared to conventional cautery (OR 0.75; 95% CI 0.58-0.98) (p = 0.04). Use of alternative sources of cautery added 4.95 min onto operative time (95% CI 2.45-7.45) which was statistically significant (p < 0.0001). After controlling for confounding variables, there was a statistically significant lower rate of post-operative hematoma in thyroidectomies performed using alternative sources of cautery compared to those performed with traditional hemostatic methods. Alternative sources of cautery increased operative time by 4.95 min.
