Introduction. Ligature strangulation represents a violent mechanical asphyxiation caused by tightening a loop around the victim?s neck, pulled either by an active or passive force. Mechanism of death is most often due to cerebral hypoxia caused by compression of blood vessels which feed the brain, but it can also occur either due to compression and closing the air passages or by stimulating the superior laryngeal nerve. Case Report. An 81-year-old woman was found in her home lying across the couch with a bathrobe belt tied around her neck and a knot at the back side. Body examination showed congestion of the face, conjunctival petechiae as well as a ligature mark in the middle of the neck. The internal examination revealed hematomas on the left side of the tongue, on its base and in the neck muscles on the left side. Conclusion. Thorough forensic expertise of a strangulation case includes the circumstances surrounding the death, detailed information of a crime scene and a complete autopsy report. The relevant pieces of information obtained from each of the investigation phase can be vital for making the right decision about the cause of death.

Context: Non-ketotic hyperglycemia is a rare cause of chorea. Clinical findings are usually unilateral and potentially reversible after treatment for hyperglycemia. Hyperglycemia leads to asymmetric multifocal petechial hemorrhages of the basal ganglia, leading to a dysfunction of neuronal networks that connect the basal ganglia and the motor cortical areas, mainly affecting the subthalamic nucleus and contralateral striatum, which is highlighted by typical hyperdense lesions of the basal ganglia in computed tomography (CT) of the brain. This study aimed to report a case of a patient with choreiform movements due to a rare etiology of hyperglycemia nonketotic in a Hospital Public of Joinville, SC. The study was carried out through the collection and analysis of a patient’s medical record. Case report: Female patient, 54 years old, who presented for 6 days choreiform movements in the face, left upper limb and, discreetly, in the left lower limb. Snake tongue sign and milkmaid’s grip positive, without dysarthria. In the laboratory exam, glucose of 600 mg / dL; without further changes. Cranial tomography showed hyperdensity in the putamen region on the right. The treatment was started to obtain better glycemic control and Risperidone 3 mg / day. Conclusions: It is concluded, then, that non-ketotic hyperglycemia is an uncommon, but reversible cause of chorea, and may manifest itself due to an uncontrolled non-ketotic diabetes mellitus. Its pathogenic mechanism remains to be clarified. In addition, clinical, epidemiological, imaging and laboratory findings, together, corroborate for early diagnosis and proper management.

The objective of this case report is to relate a malformation in a newborn male girolando breed bovine calf. The bovine presented craniofacial duplication and was sent to the Animal Diagnosis Center (CDA) at the Federal University of Rondônia (UNIR). The descriptive study of the main anatomical changes observed during the desiccation of the facial muscles and removal of the brain was performed. The anatomical parts were exposed on a board for photo documentation and description of the malformations. The diagnosis of incomplete diprosopia was made by observing the congenital lesions on the face and brain characterized through the craniofacial junction without total head separation; the animal presented triophthalmia, duplication of nasal and oral structures with lateral deviance of the right jaw side. The animal’s cerebellum was found in the opposite position and was united with the two brains through the cerebral peduncles in a caudal cranial orientation. In this case report, it was not possible to determine the malformation etiology, however, it emphasizes the importance of diprosopia in bovine and it suggests the need of further studies about the mechanism that produce cranial alterations.

Abstract Background Although intracranial traumas by penetrating foreign objects are not absolute rarities, the nature of trauma, the kind of object, and its trajectory make them a one of a kind case every time they occur. Whereas high-velocity traumas mostly result in fatalities, it is the low-velocity traumas that demand an individualized surgical strategy. Methods We present a case report of a 33-year-old patient who was admitted to our department with a self-inflicted transorbital pen injury to the brain. The authors recall the incident and the technique of the pen removal. Results Large surgical exposure of the pen trajectory was considered too traumatic. Therefore, we opted to remove the pen and have an immediate postoperative computed tomography (CT) scan. Due to its fragility, the pen case could only be removed with a screwdriver, inserted into the case. Post-op CT scan showed a small bleeding in the right peduncular region, which was treated conservatively. The patient was transferred back to intensive care unit and woken up the next day. She lost visual function on her right eye, but suffered from no further neurologic deficit. Conclusion Surgical management of removal of intracranial foreign bodies is no routine procedure. Although some would favor a large surgical exposure, we could not think of an approach to do so without maximum surgical efforts. We opted for a minimal surgical procedure with immediate CT scan and achieved an optimal result. We find this case to be worth considering when deciding on a strategy in the future.

Brain connectivity plays an important role in determining the brain region’s function. Previous researchers proposed that the brain region’s function is characterized by that region’s input and output connectivity profiles. Following this proposal, numerous studies have investigated the relationship between connectivity and function. However, this proposal only utilizes direct connectivity profiles and thus is deficient in explaining individual differences in the brain region’s function. To overcome this problem, we proposed that a brain region’s function is characterized by that region’s multi-hops connectivity profile. To test this proposal, we used multi-hops functional connectivity to predict the individual face activation of the right fusiform face area (rFFA) via a multi-layer graph neural network and showed that the prediction performance is essentially improved. Results also indicated that the two-layer graph neural network is the best in characterizing rFFA’s face activation and revealed a hierarchical network for the face processing of rFFA.

Patient M., 23 years old, consulted a dermatologist with complaints of rashes on the face, which had bothered since childhood. On objective examination, skin lesions were widespread. A visual examination revealed spots of hypopigmentation, angiofibromas of the face, shagreen fate of the skin, periungual fibromas. She was diagnosed with tuberous sclerosis. Further examination revealed a neoplasm in the brain and right kidney, damage to the lungs, tubular bones, lymphadenopathy. The patient continues to be monitored by a neurologist and therapist. Based on the results of CT scan of the chest organs, an oncologist's consultation was scheduled to conduct an oncology search. Thus, with skin manifestations characteristic of this disease, it is necessary to conduct a comprehensive examination to identify concomitant pathology and early diagnosis of complications.

Lateralization, or asymmetry in form and/or function, is found in many animal species. Brain lateralization is considered adaptive for an individual, and often results in “handedness,” “footedness,” or a side preference, manifest in behavior and morphology. We tested for lateralization in several behaviors in a wild population of Magellanic penguins Spheniscus magellanicus breeding at Punta Tombo, Argentina. We found no preferred foot in the population (each penguin observed once) in stepping up onto an obstacle: 53% stepped up with the right foot, 47% with the left foot (n = 300, binomial test p = 0.27). We found mixed evidence for a dominant foot when a penguin extended a foot for thermoregulation, possibly depending on the ambient temperature (each penguin observed once). Penguins extended the right foot twice as often as the left foot (n = 121, p < 0.0005) in 2 years when we concentrated our effort during the heat of the day. In a third year when we observed penguins early and late in the day, there was no preference (n = 232, p = 0.59). Penguins use their flippers for swimming, including searching for and chasing prey. We found morphological evidence of a dominant flipper in individual adults: 60.5% of sternum keels curved one direction or the other (n = 76 sterna from carcasses), and 11% of penguins had more feather wear on one flipper than the other (n = 1217). Right-flippered and left-flippered penguins were equally likely in both samples (keels: p = 0.88, feather wear: p = 0.26), indicating individual but not population lateralization. In fights, aggressive penguins used their left eyes preferentially, consistent with the right side of the brain controlling aggression. Penguins that recently fought (each penguin observed once) were twice as likely to have blood only on the right side of the face (69%) as only on the left side (31%, n = 175, p < 0.001). The proportion of penguins with blood only on the right side increased with the amount of blood. In most fights, the more aggressive penguin used its left eye and attacked the other penguin’s right side. Lateralization depended on the behavior tested and, in thermoregulation, likely on the temperature. We found no lateralization or mixed results in the population of Magellanic penguins in three individual behaviors, stepping up, swimming, and thermoregulation. We found lateralization in the population in the social behavior fighting.

Background: Orbitocutaneous fistula is a known complication of orbital exenteration. Orbitocutaneous fistula arising from a tonsillectomy are quite uncommon. Risk factors for fistula development are sinus diseases, radiotherapy, inadvertent sinus penetration during mid-face and other related surgeries. Case Report: MS is a 16-year-old girl who presented with swelling of the right side of the face and neck of ten days duration following local tonsillectomy at home. Ocular examination findings showed lid swelling, ecchymosis, pus point in the medial third of the upper lid of the right eye which gave way and formed a sinus tract with the commencement of antibiotics.  Discussion: Although orbitosinocutaneous fistula is uncommon with tonsillectomy however fistulae may develop following poorly performed procedure by a non-professional who may tamper with the sinuses in the course of surgery. Since asepsis was not observed, there may have also been upward track of infection to the orbit. Conclusion: Orbitosinocutaneous fistula could be a complication of poorly performed tonsillectomy.

J. T., a cabinet-maker, was brought to the Asylum from Stirling by two policemen, on the 29th July, about 7 p.m. A certificate of emergency had alone been granted, and there was no further information regarding his case in the form of admission. He was about 30 years of age. He looked in bad health, exhausted, and miserable, and his head was bound up with a handkerchief. He asked the attendant to be careful in removing this, as there was a frightful gash underneath it. When it was undone, however, there was no wound to be seen. There was a large black mark over the right side of his face and ear, which looked as if produced by gunpowder, mixed with a little blood. There was a drop of serous fluid in the ear. The patient answered questions intelligently, though in a languid, dejected manner. He put out his tongue freely when asked. It was foul. Pulse was about 80. The policemen stated that they had been informed he had attempted to shoot himself with a double-barrelled pistol, and that the police-surgeon who had seen him thought the pistol could only have been charged with powder. The patient denied this, however, and said that the pistol had been loaded with bullets. The policemen further stated that after apparently firing both barrels of the pistol at his head early on the morning of the 28th, he had attempted to drown himself in the river Forth. As there was no external wound, nor any symptoms of injury to the brain, and as it was about 40 hours since he had attempted to shoot himself, I concluded that he had missed his aim, and caused nothing more serious than a gunpowder mark on his face. He walked along with an attendant to one of the wards. He there conversed a little with the attendants, as he had been doing in the waiting-room before I saw him, and told them a little about his history. He mentioned that he was married; that he and his wife did not agree; that he had been living away from her for some time; and that he had been drinking pretty freely. He complained of thirst, and said he had a headache. He drank a good deal of water. I saw him again in about half-an-hour, and talked with him a little about himself. He looked ill and wretched, and complained of a tremendous headache. At eight o'clock he walked up stairs with the other patients, undressed himself, and went to bed in a dormitory. After going to bed he became very restless, kicked the clothes about, talked incoherently, and shouted for “John” (apparently his brother). About 10.30 he was removed to a single room. He walked quietly along, and got into his new bed. When visited about an hour afterwards, he was lying in bed, but talking nonsense. At six in the morning the attendant went into his room to waken him. He was lying dead on a mattress on the floor, with his face downwards, his mouth and nose being firmly pressed against the mattress. I saw him almost immediately. He had all the appearance of a person who had died from suffocation, and probably in a convulsion. The face and neck were livid and swollen. The tongue was protruded between the teeth; bloody mucus was on the sheet, and seemed to have come from his mouth and nose. A post-mortem examination was made at the instance of the Procurator Fiscal, by Dr. Moffat, of Falkirk, and myself, at 5 p.m., of which the following is a report:—

Facial fractures caused by gunshots are a major challenge for oral and maxillofacial surgeons. Underdeveloped countries present a higher rate of homicides committed by gunshots than developed countries. This case report presents a 25 year-old male victim of a gunshot wound to the mandible, evolving into a complex fracture. The fracture was treated using rigid internal fixation. After 18 months of follow-up, the patient presents good facial appearance and masticatory activity. The gunshot caused the permanent paralysis of the right mandibular branch of the facial nerve. We managed to preserve the involved teeth and mandibular integrity, with complete bone healing. Despite the late infection following plate fixation, healing occurred without further complications, indicating that blood supply was maintained.

Aim. The article deals with studying the systemic protective mechanisms of the brain against hypoxia during water immersion in highly skilled swimmers. Material and methods. 25 males aged 18–20 years were examined: 9 masters of sports, one master of sports of international class and 15 people not involved in sports. The study of cerebral blood flow was carried out by rheoencephalography (REG). REG was recorded at rest, when the face was immersed in water and during recovery. Examination was carried out 2 hours after the morning training session. In addition to cerebral blood flow, ECG and blood pressure were recorded at rest, during water immersion and recovery. Statistical data processing was performed using nonparametric Mann–Whitney and Wilcoxon criteria. Results. It was revealed that athletes at rest demonstrated more pronounced asymmetry of blood circulation and higher blood flow in the right hemisphere than people not involved in sports. However, during water immersion, the asymmetry disappears, blood flow improves, especially in the left hemisphere in the carotid artery territory as a result of a decrease in the tone of small vessels. In people not involved in sports, protective mechanisms are less pronounced. Conclusion. Vast experience in sports activities related to exercises performed in water and to training hypoxic exercises contributed to effective protective mechanisms against hypoxia based on the diving reflex.
