The crossbow is an ancient ranged weapon originally conceived for war and hunting. Although nowadays its use in warfare has been surpassed by firearms, it continues to be used in hunting, sports and recreation. The authors present the case of a 40-year-old man who suffered from severe depression. When his condition further deteriorated, doctors ordered a forced hospitalization but, just a few hours before the measure became effective, the man committed suicide using a crossbow. The autopsy and police investigation showed possession of the crossbow darts which the man used to shoot himself in the head...

OBJECTIVE Cranial defects can result from trauma, infection, congenital malformations, and iatrogenic causes and represent a surgical challenge. The current standard of care is cranioplasty, with either autologous or allogeneic material. In either case, the intrinsic vascularity of the surrounding tissues allows for bone healing. The objective of this study was to determine if mechanotransductive gene manipulation would yield non-weight-bearing bone regeneration in a critical size calvarial defect in mice. METHODS A mouse model of Sost deletion in Sost knockout (KO) mice was created in which the osteocytes do not express sclerostin...

Bacterial purulent meningoencephalitis (BPME) is a life-threatening infectious disease caused by various pyogenic bacteria. The disease is defined as the inflammatory process of leptomeninges (visceral layer, pia mater and arachnoid membrane) and brain parenchyma with exudates in the subarachnoid space and surrounding brain structures. The aim of the study was to define the predisposing factors responsible for the occurrence of BPME, as well as the possible correlation between the presence of predisposing factors and patient demographic characteristics, etiology and outcome of the disease...

Sixth nerve palsy is frequently due to infectious orbital lesions, trauma, elevated intracranial pressure, brainstem lesions, and vasculopathies. Here, we describe a rare cause of sixth cranial nerve (CN) palsy secondary to calvarial and orbital metastasis of prostate carcinoma. The diagnosis of the prostate carcinoma with sixth CN palsy is a very rare condition. A 66-year-old male patient presented with complaints of blurred vision, double vision, and inability to move outward in the right eye for 3 weeks...

Pneumocephalus is a rare condition characterized by the presence of gas within the cranial cavity. This gas arises either from a trauma, tumor, surgical procedure, or occasionally from infection. Pneumocephalus secondary to chronic otitis media is an extremely rare phenomenon. We describe here a 70-year-old male, a known case of chronic suppurative otitis media who presented with sudden onset severe thunderclap headache and was eventually diagnosed as pneumocephalus.

Field triage guidelines recommend transport of head-injured patients on anticoagulants or antiplatelets to a higher-level trauma center based on studies suggesting a high incidence of traumatic intracranial hemorrhage (tICH). We compared the incidence of tICH in older adults transported by EMS with and without anticoagulation or antiplatelet use and evaluated the accuracies of different sets of field triage criteria to identify tICH. This was a prospective, observational study at 5 EMS agencies and 11 hospitals...

Carotid cavernous fistula (CCF) is an abnormal vascular shunt from the carotid artery to the cavernous sinus. They are commonly classified based on hemodynamics, etiology or anatomically. Hemodynamic classification refers to whether the fistula is high or low flow. Etiology is commonly secondary to trauma or can occur spontaneously in the setting of aneurysm or medical conditions predisposing to arterial wall defects. Bilateral carotid cavernous fistulas are rare. We present a case of bilateral CCF secondary to trauma...

In the first years of life, subdural haemorrhage (SDH) within the cranial cavity can occur through accidental and non-accidental mechanisms as well as from birth-related injury. This type of bleeding is the most common finding in victims of abusive head trauma (AHT). Historically, the most frequent cause of SDHs in infancy is suggested to be traumatic damage to bridging veins traversing from the brain to the dural membrane. However, several alternative hypotheses have been suggested for the cause and origin of subdural bleeding...

Methylmethacrylate bone cement (MM-BC) is one of the reconstructive methods: during cranioplasty to correct cranial defects following trauma or cranial surgery. Perfect intraoperative immobilization of the MM-BC is crucial to ensure correct subsequent shaping to best improve contour defects. Current immobilization techniques reported are time-consuming and involve complex metalwork. The authors hereby present a technique that may simplify the immobilization process by using histoacryl glue to secure the MM-BC...

PURPOSE: Cranial defects in children have been repaired with various materials ranging from autologous bone to synthetic materials. There is little published literature on the outcomes of titanium mesh cranioplasty (TMC) in calvarial reconstruction in the pediatric population. This study evaluates a pediatric cohort who underwent calvarial defect reconstruction with titanium mesh and assesses the efficacy and outcomes of TMC. METHODS: An Institutional Review Board approved retrospective review of patients ≤18 years of age who underwent cranioplasty from 1999 to 2014 at 2 centers was performed...

Although extrahepatic metastases from hepatocellular carcinoma (HCC) are present in only 5-15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man previously diagnosed with alcohol-induced cirrhosis of the liver and HCC. The patient was admitted presenting progressive left hemiparesis and headache which started 2 days earlier, with no history of cranioencephalic trauma...

BACKGROUND AND PURPOSE: Head CT is the current neuroimaging tool of choice in acute evaluation of pediatric head trauma. The potential cancer risks of CT-related ionizing radiation should limit its use in children. We evaluated the role of MR imaging, including a "black bone" sequence, compared with CT in detecting skull fractures and intracranial hemorrhages in children with acute head trauma. MATERIALS AND METHODS: We performed a retrospective evaluation of 2D head CT and brain MR imaging studies including the black bone sequence of children with head trauma...

Cavernous sinus syndrome (CSS) is a condition characterized by multiple cranial nerve palsies manifesting with ophthalmoplegia, ptosis, and facial sensory loss due to involvement of adjacent cranial nerves. Tumors, trauma, and vascular, infectious, and noninfectious inflammatory disorders have all been described as causes. Lymphomas have been reported to involve the cavernous sinus, both as primary cavernous sinus lymphomas or as secondary lesions. Here, we describe the case of a 63-year-old-man with untreated chronic lymphocytic leukemia (CLL), diagnosed 4 years earlier, who presented with CSS...

Simon S Buttrick, Daniel Eichberg, Sheikh C Ali, Ricardo J Komotar
BACKGROUND AND IMPORTANCE: Traditional scalp closure technique following elective craniotomy involves placement of staples or a continuous running suture. Despite low complication rates, these techniques are often considered to be disfiguring by patients, contribute to the psychosocial trauma of brain surgery, and are associated with discomfort during postoperative staple or suture removal. Some authors have described scalp closure using intradermal absorbable suture, but this technique likely does not reach the tensile strength of closure using traditional methods, and requires knots at the apices of the incision, which can act as a nidus for infection...
