The objective – to presents the observation of combined treatment of a patient with arteriovenous malformation of the lower jaw.A man, 21 years old, was hospitalized in the Scientific-Practical Center of Endovascular Neuroradiology NAMS of Ukraine with complaints of bleeding from a tooth socket after an attempt to remove the 6th tooth (first painter) of the lower jaw on the left. According to the performed survey radiography of the lower jaw, an aneurysmal bone cyst was revealed in the body of the lower jaw on the left, corresponding to the localization of bleeding. According to cerebral angiography, an arteriovenous malformation of the lower jaw was revealed on the left, the afferent arteries of which were: the right facial artery (a branch of the right external carotid artery (ECA)), the left facial artery (a branch of the left ECA), the lower alveolar artery, the superior-posterior alveolar artery (branches of the maxillary artery ‒ the terminal branch of the left ECA) with drainage into a vein, which was located in the body of the lower jaw. In order to exclude the malformation from the bloodstream and prevent bleeding, a controlled embolization of the malformation was performed using non-spherical emboli – polyvinyl alcohol (PVA) particles from Cook, USA. Using a transfemoral approach, a guide catheter was inserted into the orifice of the ECA, then a Headway 27 microcatheter (Microvention, USA) was passed through it along a Traxes 14 guide wire (Microvention, USA), the afferent arteries of the malformation were selectively cathete-rized in turn, and embolization was performed after superselective angiography. The patient was discharged in a satisfactory condition. Two weeks after the operation, the bleeding resumed. The performed control cerebral angiography revealed a relapse of the malformation with a change in its angioarchitectonics ‒ the filling of the malformation in the late arterial and venous phases of cerebral blood flow was noted. Re-embolization was performed using PVA emboli (Cook), which was supplemented by transcutaneous puncture of the drainage vein in the mandible and its embolization with histoacryl (B. Braun, Germany) and lipiodol (Guerbet, France) in a 1 : 1 ratio. Results. As a result of using this technique, it was possible to turn off the malformation completely. For 6 months from the moment of surgery, no bleeding was noted, and subsequently the patient had a tooth removed without complications.Conclusions. The proposed method for treating arteriovenous malformation of the lower jaw, proposed in this case, showed the effectiveness of a combination of endovascular embolization in combination with transcutaneous embolization of the draining vein and can be successfully used to treat this pathology.

Acute Epidural Hematoma

Abstract BACKGROUND AND IMPORTANCE Intraosseous dural arteriovenous fistulae (DAVF) are rare, especially those with drainage into the diploic venous system. The clinical presentation depends on the location of the lesion. This is the first report of an intraosseous DAVF associated with acute epidural hematoma. CLINICAL PRESENTATION A 25-year-old man presented with headache and nausea. Imaging of the brain revealed abnormal signals indicative of acute epidural hematoma in the right frontal convexity. Angiography demonstrated a DAVF in the region of the frontal bone. Right external carotid artery angiography showed that the DAVF was fed mainly by the right middle meningeal artery with drainage into diploic veins. Immediately after embolization of the middle meningeal and the distal internal maxillary artery with 17% N-butyl-2-cyanoacrylate, the shunt was completely occluded. The patient was discharged 4 days later without clinical complications. CONCLUSION Intraosseous DAVF can be treated by surgical resection or endovascular embolization. Curative treatment requires careful inspection of the angiographic architecture and microsurgical anatomy.

IntroductionMechanical thrombectomy (MT) has been widely accepted as a safe and effective treatment for acute ischemic stroke (AIS). Development of stent retriever devices has been intensively developed over the past two decades. In this study, we compared the effectiveness and safety of a new thrombectomy device with Solitaire FR for the treatment of AIS models.MethodsMechanical performance of stent retrievers was tested in vitro. Thrombin-induced thrombus was pre-injected into the right distal external carotid-maxillary artery in 18 dogs to create an acute thrombus occlusion model, and these animals were divided into a Tonbridge group (n=9, with Tonbridge stent Tonbridge Medical Technology) and a Solitaire group as control (n=9, with Solitaire stent, ev3 Neurovascular). Final flow restoration, side branches, recanalization time, distal vessel embolism, and device-related complications were recorded and compared. A post-procedure angiogram was obtained at 30 and 90 days after thrombectomy. Device manipulation-related damage to the arterial walls was evaluated histologically.ResultsIn vitro test showed that the maximum friction within the microcatheter was 0.763 for the Tonbridge device and 0.784 n for the Solitaire (P>0.05). Slight increase in radial force was noticed for the Tonbridge (0.035 N/mm vs 0.031 N/mm of Solitaire, P>0.05). Eighteen and 16 retriever attempts were done in the Tonbridge (mean 2.0 attempts) and the Solitaire (mean 1.8 attempts) groups (P=0.74). The Tonbridge device led to good flow restoration in all nine (100%) models compared with eight (88.9%) in the Solitaire group (P=0.30). Side branches' influence (P=0.39), distal thromboembolism (P=0.60), and device-related complications (P=1.00) found no difference between the two groups. The rates of disruption of the internal elastic lamina (IEL) were 8.3% (2/24) and 4.2% (1/24) of the specimens, respectively (P=0.683). TICI 2b/3 flow of the right CCA were similar between the two groups at 1 (6/6 vs 6/6) and 3 months (6/6 vs 6/6) follow-up (P>0.05).ConclusionOur preliminary study indicated this new device was technically feasible and effective to be used in thrombectomy for the treatment of acute thrombus occlusion in canine models.

This is the case of a 14-year-old female who presented with headache and seizures. Cranial magnetic resonance imaging revealed an arteriovenous malformation (AVM) located at the posterior portion of the right-sided fusiform gyrus. Cerebral angiography showed that the AVM was fed mainly by branches from the inferior temporal trunk of the posterior cerebral artery. The main venous drainage was to the right transverse sinus through the tentorial vein. The AVM was totally excised through the paramedian supracerebellar-transtentorial approach with the patient in a semisitting position. Postoperative MRI and cerebral angiography confirmed the total resection. The patient was discharged on the 5th postoperative day without neurological deficit.The video can be found here: https://youtu.be/QPrUl8AP7G8.

The authors report two rare cases of arteriovenous malformation (AVM) associated with moyamoya disease. An AVM, supplied by transdural communicating arteries, was located in the right occipital lobe in one patient who presented with ischemia. The second AVM, which was supplied by basal moyamoya vessels, was located in the posterior part of the left frontal lobe in a patient who developed intracerebral hemorrhage that occupied the left basal ganglion. A review of the literature revealed a total of 12 AVMs in 11 patients with moyamoya disease including our cases. All AVMs were cerebral and two were supplied by normal cerebral arteries, whereas six AVMs were supplied by basal moyamoya vessels at the base of the brain and four AVMs were supplied by external carotid arteries through the transdural communicating arteries. Every AVM drained into deep or cortical cerebral veins. These findings suggest that the hyperangiogenic character of moyamoya disease occasionally induces the development of acquired arteriovenous shunts that mimic AVM.

It has been found that pain in various parts of the body can be temporarily eliminated by mechanically suppressing or stimulating the front tooth. Some typical examples of this are described in this article. We know which teeth represent which organs, but we also have diagrams that show the cause of the pain, such as changes in certain areas of the electrocardiogram, and those possible areas are shown somewhere in the electrocardiogram. One minute downward pressure on the tip of any one of the front 3 teeth (1st incisor, 2nd incisor, and canine) at the right and left sides of the upper and lower jaw by a wooden toothpick induced temporary disappearance (20 min-4 hours) of abnormally increased pain parameters (pain grading, Substance P, & TXB2), and cancer parameters (Telomere, Integrin α5 β1, Oncogene C-fos Ab2, etc. of Astrocytoma, Glioblastoma, squamous cell carcinoma of esophagus, adenocarcinoma of lung, breast cancer, adenocarcinoma of colon, prostate cancer). The effect included temporary disappearance of headache, toothache, chest and abdominal pain, and backache, often with improved memory & concentration. Since these beneficial changes resembled the effects of giving one optimal dose of DHEA, increase of DHEA was measured. Above mechanical stimulation of one of these front teeth increased abnormally reduced DHEA levels of less than 10 ng to normal 100–130 ng BDORT units and normal cell (NC) telomeres from markedly reduced values to near normal values, and improved acetylcholine in the Hippocampus. Large organ representation areas for the Adrenal gland & Hippocampus may exist at these front teeth. This method can be used for emergency pain control and can explain the beneficial effect of bruxism and tooth brushing, through the increase of DHEA levels and activities of the Hippocampus by increasing Acetylcholine. Increasing NC telomere to optimally high level resulted in disappearance of pain and improvement or significant reduction of malignant tumor.

AbstractThe aim was to determine the variations in the level of origin of carotid bifurcation and diameters of the common, internal, and external carotid arteries which is clinically important for several interventional procedures. Therefore, 165 human embalmed corpses were dissected. The data collected were analyzed using the Chi square-test and the Pearson correlation test. The results of previous studies have been reviewed. In relation to the level of the carotid bifurcation, taking as a reference point the hyoid bone, the values ranged from 4 cm below the hyoid body to 2.5 cm above the body of the hyoid, being the average height—0.33 cm, with a standard deviation of 1.19 cm. The right carotid bifurcation was established at a higher level (x = − 0.19 cm.) than the left one (x = − 0.48 cm.) (p = 0.046). On the contrary, no significant gender differences could be observed. The arterial calibres of the common and internal carotid arteries were higher in male than female. In the internal carotid artery (X = 0.76 cm.), the left was greater than the right (X = 0.72 cm.) (P = 0.047). However, no differences in the distribution of the calibre of the external carotid artery were found neither by side nor gender. Variations in the level of bifurcation and calibres of carotid arteries are relevant for interventional radiology procedures and head and neck surgeries. Knowledge of these anatomical references might help clinicians in the interpretation of the carotid system.

No one wants to be treated like an object, regarded as an item of property, or put up for sale. Yet many people frame personal autonomy in terms of self-ownership, representing themselves as property owners with the right to do as they wish with their bodies. Others do not use the language of property, but are similarly insistent on the rights of free individuals to decide for themselves whether to engage in commercial transactions for sex, reproduction, or organ sales. Drawing on analyses of rape, surrogacy, and markets in human organs, this book challenges notions of freedom based on ownership of our bodies and argues against the normalization of markets in bodily services and parts. The book explores the risks associated with metaphors of property and the reasons why the commodification of the body remains problematic. The book asks what is wrong with thinking of oneself as the owner of one's body? What is wrong with making our bodies available for rent or sale? What, if anything, is the difference between markets in sex, reproduction, or human body parts, and the other markets we commonly applaud? The book contends that body markets occupy the outer edges of a continuum that is, in some way, a feature of all labor markets. But it also emphasizes that we all have bodies, and considers the implications of this otherwise banal fact for equality. Bodies remind us of shared vulnerability, alerting us to the common experience of living as embodied beings in the same world. Examining the complex issue of body exceptionalism, the book demonstrates that treating the body as property makes human equality harder to comprehend.

The  authority  of justice in Indonesia  is executed by  the Supreme Courts and  the  justice  boards/body under the Supreme Courts, including  the general  justice, religious affairs justice, military justice,  state administration  justice,  and  the Constitution Court. According to  certainty in  the Act of  Tax Court, Article1, clause  (5),  tax  dispute   refers to the legal dispute arising in the  taxation  affairs between the  tax payer or the  body  responsible for the  tax with   the government   executives  ( Directorate General of Tax) as the consequence of   the issue of  the decree for the  appeal  to the Tax  Court in accordance with the  tax Act, including the  charge  against the  execution of collection   in accordance with the  Act of Tax Collection by force. The  formation of Tax Court is  designed by  the Executives, in this case, the  Department of Finance, specifically  the Directorate   General  of Tax  which has the right to issue  law  more technical about  tax accord to Article 14,  letter A,  President Decree  no. 44  year 1974,  concerning the  basic  organization of the Department.  Based on  it,  it  is clear that  in addition to execute the government  rules and policy,  this body  has to execute judicial   rules and policy. This is against the  principles of  Judicative  Power/Authority in Indonesia,  which   clearly states that this body  should be under the Supreme Court.   Therefore. It is suggested that   the Act  No UU no.14 Year 2012 concerning  Tax Court   be revised  in accordance with the system of  Power Division  of Justice  as  stated in 45 Constitutions.
