Ameloblastoma is an infiltrative benign neoplasm in the mandible or maxilla that is locally aggressive with rare metastasizing capacity. This lesion is the most common tumor of the odontogenic epithelium. However, its occurrence in children is low, representing only 10–15% of all reported ameloblastoma cases. In treating such benign neoplasms in pediatric patients, the preservation of vital structures such as the inferior alveolar nerve (IAN), deciduous teeth, tooth buds, and nerves with proper post-operative management to maintain normal mandibular growth is imperative. A five-year-old boy with painless swelling and displaced teeth in the right mandible was diagnosed with plexiform ameloblastoma. Instead of a radical approach, the patient was treated conservatively using decompression and routine irrigation along with long-term follow-up. Functional appliance treatment was provided using a Frankel appliance to preserve and induce normal growth of the jaw. After eight years, there was no recurrence of the ameloblastoma, and normal mandibular growth of the patient was observed. Pediatric plexiform ameloblastoma should be treated with a conservative approach considering the preservation of important anatomic structures and further mandibular growth. Moreover, functional appliance therapy should be considered as an integral part of treatment for pediatric ameloblastoma and other tumors in children to maintain and induce normal growth of the mandible.

Tooth Buds

Children (below 13 yrs of age) are usually susceptible to cranio facial trauma because of their greater cranial mass to body ratio. When compared to adults, the pattern of fractures and frequency of associated injuries are similar but the overall incidence is much lower. Treatment is usually performed without delay and can be limited to observation or closed reduction in non-displaced or minimally displaced fractures. Operative management should involve minimal manipulation and may be modified by the stage of skeletal and dental development. Open reduction and rigid internal fixation is indicated for severely displaced fractures. When tooth buds within the mandible do not allow internal fixation with plates and screws, this can be achieved with a mandibular compression splint fixed to the teeth, to the mandible with circum-mandibular wire. Children require long-term follow-up to monitor potential growth abnormalities. A case of a 9-year-old boy with fractured body of mandible managed by closed reduction using occlusal acrylic splint and circum mandibular wiring is presented.

A high rate of nerve injury and related consequences are seen during implant placement in the posterior mandibular arch. An approach has been proposed to avoid nerve injury by dodging the inferior alveolar nerve (IAN) while placing an implant. A prospective study with a total of 240 CBCT (cone beam computed tomography) images of patients with three dentate statuses, namely, edentulous (group I), partially edentulous (group II) and dentate (group III) were included in the study. The nerve path tracing was done on CBCT images with On-demand 3D software. The three dimensions, i.e., the linear distance from the outer buccal cortical plate to the inferior alveolar nerve (BCPN), linear distance from the outer lingual cortical plate to the inferior alveolar nerve (LCPN) and linear distance from the midpoint of the alveolar crest to the inferior alveolar nerve (ACN) were assessed. The data were presented and analyzed between variables using one-way ANOVA and independent t-test in SPSS version 21.LCPN of the right 1st premolar region (p < 0.05) was significantly different among the groups with edentulous subjects recorded with the minimum value (6.50 ± 1.20 mm). Females were found to have significantly (p < 0.05) less available bone (6.03 ± 1.46 mm) on the right side of the mandibular jaw compared to males in edentulous group of patients. On comparing age groups for partially edentulous subjects, LCPN of the right 1st premolar region had significantly (p < 0.05) less available bone (6.03 ± 0.38 mm) in subjects with age ≥54 years. The IAN follows a lingual course in the molar region and later flips to the buccal side in the premolar region. The LCPN dimension in the 1st and 2nd premolar region was found to be more than 6 mm irrespective of age, gender and side of the jaw. Thus, it can be considered as a suitable site for placing implants while bypassing the IAN with CBCT assessment remaining as the mainstay in the pre-surgical phase.

Anatomy and physiology are the basis of human body functioning and as we have progressed in management of various diseases, we have understood that physiological intervention is always better than an anatomical one. For more than 50 years, a standard approach to permanent cardiac pacing has been an anatomical placement of transvenous pacing lead at the right ventricular apex with a proven benefit of restoring the rhythm. However, the resultant ventricular dyssynchrony on the long-term follow-up in patients requiring more than 40% ventricular pacing led to untoward side effects in the form of heart failure and arrhythmias. To counter such adverse side effects, a need for physiological cardiac pacing wherein the electrical impulse be transmitted directly through the normal conduction system was sought. His bundle pacing (HBP) with an intriguing alternative of left bundle branch pacing (LBBP) is aimed at restoring such physiological activation of ventricles. HBP is safe, efficacious, and feasible; however, localization and placement of a pacing lead at the His bundle is challenging with existing transvenous systems due to its small anatomic size, surrounding fibrous tissue, long-learning curve, and the concern remains about lead dislodgement and progressive electrical block distal to the HBP lead. In this article, we aim to take the reader through the challenging journey of HBP with focus upon the hardware and technique, selective versus nonselective HBP, indications and potential disadvantages, and finally the future prospects.

Abstract Background Inguinal endometriosis (IEM) is a rare extra pelvic endometriosis. Here, we study the clinical characteristics, management strategies, and long-term gynecological outcomes of IEM patients at Beijing Chaoyang Hospital. Case presentation Three patients presented with a total of four lesions (one on the left side, one on the right side, and one bilaterally). The diameters of the four lesions were 2 cm, 2 cm, 3.5 cm and 1.5 cm, respectively. Two patients were admitted with inguinal hernias. Two patients were admitted with endometrioses—one with ovarian endometriosis and one with pelvic endometriosis. The hernia sac was repaired concomitantly via excision of the round ligament in two patients. One patient underwent a concomitant laparoscopy for gynecologic evaluations, including an ablation to the peritoneal endometriosis, and resection of the left uterosacral ligament endometriosis and pelvic adhesiolysis. All lesions were located on the extraperitoneal portion of the round ligament and were diagnosed histologically. No recurrence was observed in the inguinal region. All patients diagnosed with adenomyosis were treated with medication alone without any complaints. Conclusions Inguinal endometriosis can occur simultaneously with pelvic endometriosis. In most cases, a concomitant hernia sac appears together with groin endometriosis. Clinical management should be individualized and performed in tandem with general practitioners and obstetrics & gynecology experts. Pelvic disease, in particular, should be followed-up by a gynecologist.

Abstract Objectives Data on normal mandibular development in the infant is lacking though essential to understand normal growth patterns and to discriminate abnormal growth. The aim of this study was to provide normal linear measurements of the mandible using computed tomography performed in infants from 0 to 2 years of age. Material and methods 3D voxel software was used to calculate mandibular body length, mandibular ramus length, bicondylar width, bigonial width and the gonial angle. Intra- and inter-rater reliability was assessed for these measurements. They were found to be sufficient for all distances; intra-class correlation coefficients were all above 0.9. Regression analysis for growth modelling was performed. Results In this multi-centre retrospective study, 109 CT scans were found eligible that were performed for various reasons (e.g. trauma, craniosynostosis, craniofacial abscesses). Craniosynostosis patients had larger mandibular measurements compared to non-craniosynostosis patients and were therefore excluded. Fifty-one CT scans were analysed. Conclusions Analysis showed that the mandible increases more in size vertically (the mandibular ramus) than horizontally (the mandibular body). Most of the mandibular growth occurs in the first 6 months. Clinical relevance These growth models provide insight into normal mandibular development in the first 2 years of life. This reference data facilitates discrimination between normal and abnormal mandibular growth.

This study reviewed the short-term outcome of transcatheter closure of the defects within the oval fossa using an Amplatzer® Septal Occluder. From January 1997 to December 2000, 210 patients with defects within the oval fossa underwent successful transcatheter closure. We reviewed a total of 190 patients with left-to-right shunts, assessing the patients for possible complications and the presence of residual shunts using transthoracic echocardiogram at 24 h, 1 month, 3 months and one year. Their median age was 10 years, with a range from 2 to 64 years, and their median weight was 23.9 kg, with a range from 8.9 to 79 kg. In 5 patients, a patent arterial duct was closed, and in 2 pulmonary balloon valvoplasty performed, at the same sitting. The median size of the Amplatzer® device used was 20 mm, with a range from 9 to 36 mm. The median times for the procedure and fluoroscopy were 95 min, with a range from 30 to 210 min, and 18.4 min, with a range from 5 to 144 min, respectively. Mean follow-up was 20.8 ± 12.4 months. Complete occlusion was obtained in 168 of 190 (88%) patients at 24 h, 128 of 133 (96.2%) at 3 months, and 103 of 104 (99%) at one year. Complications occurred in 4 (2.1%) patients. In one, the device became detached, in the second the device embolized into the right ventricular outflow tract, the lower end of the device straddled in the third, and the final patient had significant bleeding from the site of venupuncture. There were no major complications noted on follow-up. We conclude that transcatheter closure of defects within the oval fossa using the Amplatzer® Septal Occluder is safe and effective. Long-term follow-up is required, nonetheless, before it is recommended as a standard procedure.

Abstract Introduction/Objective Adenomatoid odontogenic tumor (AOT) is an uncommon benign odontogenic tumor representing 3 to 7% of all odontogenic tumors. This tumor was first reported as adeno-ameloblastoma by Bernier and Tiecke in 1950 as it was initially assumed to be a type of ameloblastoma. In 1969, Philipsen and Bern proposed the term adenomatoid odontogenic tumor which was subsequently adopted by WHO and became the accepted terminology for this tumor. AOT is classified as a tumor of odontogenic epithelium but occasionally abnormal hard tissues consistent with dentinoid material may also be present as part of the tumor. AOT tends to occur in younger patients and 50% of the cases are diagnosed in teenagers. It occurs twice as commonly in females and frequently involves the anterior maxilla. Radiographically, AOT can appear as a radiolucent or mixed lucent-opaque lesion and may be associated with an impacted tooth. Methods/Case Report We report two unusually large expansile lesions of AOT that presented in the mandible. In the first case, the tumor presented as an expansile radiolucent lesion involving the right posterior mandible in a 32 year old female. In the second case, the tumor presented as an expansile mixed lucent-opaque lesion involving the left anterior mandible in a 21 year old female. The clinical presentation, radiographic and imaging findings, histopathologic features and treatment of these two cases will be discussed. The recommended treatment for AOT is surgical excision. The prognosis is good as this tumor seldom recurs after excision. Results (if a Case Study enter NA) NA Conclusion AOT is considered to be a non-aggressive, non-invasive and slow growing benign neoplasm. It is usually discovered on routine radiographic examination as the lesion is usually small and asymptomatic at the time of diagnosis but occasional cases that are larger in size have been reported in the literature.

Introduction Pericallosal artery (PA) aneurysms represent 2 to 9% of all intracranial aneurysms, and their management remains difficult. Objective The aim of the present study is to describe the case of an adult woman with subarachnoid hemorrhage and bilateral PA aneurysm in mirror position. Case Report A 46-year-old woman was referred to our institution 20 days after a sudden severe headache. She informed that she was treating her arterial hypertension irregularly, and consumed ∼ 20 cigarettes/day. The patient was neurologically intact at admission. A non-contrast computed tomography (CT) on the first day of the onset of the symptoms revealed hydrocephaly and subarachnoid hemorrhage (Fisher III). An angio-CT/digital subtraction arteriography showed bilateral PA aneurysms in mirror position. The patient was successfully treated with surgery via the right interhemispheric approach (because the surgeon is right-handed); the surgeon performed the proximal control with temporary clipping, and introduced an external ventricular drain at the end of the surgery. The patient was discharged on the fourth postoperative day without any additional neurological deficits or ventricular shunts. Conclusion Ruptured PA aneurysm is a surgically challenging aneurysm due to the many anatomical nuances and risk of rebleeding. However, the operative management of ruptured bilateral PA aneurysms is feasible and effective.
