Outpatient superficial partial-thickness burn care of an elderly patient successfully treated with Eppikajutsuto.

Eppikajutsuto (EPTJ) is used to reduce redundant body fluids and suppress inflammation. We observed that EPTJ shortened the duration of treatment in an elderly patient with burn injuries. A 96-year-old man suffered superficial partial-thickness burns on the dorsum of his right hand and left knee. The injuries showed early improvement with the use of EPTJ. This suggests that EPTJ could contribute to shortening the duration of healing for superficial partial-thickness burns in elderly patients who may experience slow wound healing and have a high mortality rate. Eppikajutsuto needs to be considered as a treatment for burns in primary care.

[Initial Treatment of Multiple Trauma].

Head trauma is a common neurosurgical complication. It is encountered daily at neurosurgical outpatient departments or after-hour emergency outpatient departments. In addition, most cases of patients with trauma transported by ambulance involve those with head trauma. Head trauma is a common and unavoidable neurosurgical injury. In case of a head injury, the neurosurgeon should verify the level of consciousness and perform a proper neurological examination. A head computed tomography should be performed immediately for any abnormalities. However, currently, severe trauma is often complicated by head trauma and various other injuries. When medical examinations and treatments focus only on head trauma, preventable trauma death cannot be avoided. Functional prognosis due to secondary brain injury may be exacerbated. This article presents a standardized procedure for the initial care of patients with multiple trauma and head injuries.

Neuroport® makes brain biopsy less invasive and easy even in eloquent areas.

Tissue diagnosis of brain tumours in eloquent is often done via needle biopsy but this method yields small samples that may not be representative of the whole tumour. The Neuroport® system enables a larger tumour biopsy to be taken via a burr hole. We report our experience on 5 cases October 2017 and June 2018. Brainlab® navigation was used. The diagnosis in all patients was made without worsening of their modified Rankin scale scores.

The Association Between the Duration of Chest Compression and Thoracic Injuries in Patients With Non-Traumatic Out-of-Hospital Cardiac Arrest.

BACKGROUND: Current guidelines emphasize the indispensability of high-quality chest compression for improving survival in patients who experience out-of-hospital cardiac arrest (OHCA). However, chest compression can cause thoracic injuries that may contribute to poor prognosis; therefore, the purpose of this study is to identify the predictors of thoracic injuries and evaluate the association between thoracic injuries and prognosis.Methods and Results: Between June 2017 to July 2019, Utstein-style data on 384 consecutive adult patients who experienced non-traumatic OHCA and who were transferred to our hospital (Aso Iizuka Hospital) were collected. Each patient underwent a full-body computed tomography scan. Two-hundred and thirty-four patients (76%) had thoracic injuries (Group-T). The duration of chest compression was significantly longer in Group-T than in patients without thoracic injuries (Group-N; 43 vs. 32 min, respectively, P<0.001). Multivariate analysis revealed that older age and longer chest compression duration were predictors of thoracic injuries (odds ratios 1.03 and 1.07, respectively, P≤0.005). Among patients who achieved return of spontaneous circulation, Kaplan-Meier curves showed a significantly higher cumulative survival rate in Group-N than in Group-T at the 30-day follow up (log-rank test P=0.009). CONCLUSIONS: Older age and longer chest compression duration were independent predictors of thoracic injuries due to chest compression in patients who experienced non-traumatic OHCA. Moreover, the presence of thoracic injuries was associated with worse short-term prognosis.

Two Case Studies on Inferior Mesenteric Artery Embolization for Primary Postpartum Hemorrhage.

Postpartum hemorrhage (PPH) remains a leading cause of maternal mortality. Transcatheter arterial embolization (TAE) is an effective treatment option for PPH. Among the vessels embolized, the inferior mesenteric artery (IMA) is usually not the first choice for TAE, because it is a rare source of bleeding in PPH. In this report, we describe our experience with two patients with PPH, in whom the IMA was selected on the basis of contrast-enhanced computed tomography (CECT) findings, and prompt hemostasis was achieved with TAE. CECT can provide useful clues as to the culprit artery based on the anatomical location of the hematoma and extravasation. These useful findings of CECT allow prompt TAE of rare sources of bleeding in PPH, such as the IMA.

Differentiating between Mycotic and Dissecting Aneurysms in a Case of Ruptured Distal Superior Cerebral Artery Aneurysm.

Objective: We present a case of subarachnoid hemorrhage (SAH) due to ruptured mycotic aneurysm found in the distal superior cerebellar artery (SCA). Case Presentation: A 64-year-old man was admitted to our hospital with sudden unconsciousness. He had a history of alcoholism but no family history of SAH. Computed tomography (CT) showed apparent SAH; however, CT angiography (CTA) showed no apparent cause of SAH except for two small aneurysms in the same branch of the left distal SCA. We suspected mycotic aneurysm and prescribed antibiotics. It was difficult to diagnose the condition as mycotic aneurysm because there were no vegetations or caries at the time of admission. Because there were two aneurysms in the same branch with partial dilatation and stenosis, we suspected dissecting aneurysm, but continued to administer antibiotics for possible mycotic aneurysm. After the first operation, we diagnosed mycotic aneurysm because a vegetation and valve degeneration was found. Conclusion: It is difficult to distinguish mycotic aneurysms from dissecting aneurysms because of similar appearance on imaging, especially if no vegetation is found. Nevertheless, it is important to start treatment for mycotic aneurysm. If there is the possibility of mycotic aneurysm, appropriate antibiotics should be administered, and endovascular treatment could be considered for patients with deteriorating conditions.

Absence of Microbleeds Reduces the Risk for Recurrent Intracerebral Hemorrhage.

BACKGROUND: Many known risk factors, including hypertension and hyperlipidemia cause intracerebral hemorrhage (ICH). Recently, microbleeds have been identified as one of the factors leading to ICH. While some patients have been found to have recurrent ICH, risk factors for recurrent ICH are scarcely reported. We conducted an observational study on the risk-factors of recurrent ICH, comparing stroke patients with a single hemorrhagic episode and those with recurrent ICH. METHODS: A retrospective analysis of a single-center database was performed to analyze the clinical presentation and characteristics of patients with a single and recurrent ICH. From January 2016 to December 2017, a total of 317 patients were analyzed based on suspected factors including patients' sex, age, medical history, antiplatelet therapy use, and presence of microbleeds on images. RESULTS: Of the 317 patients, 36 patients (11.4%) developed a second episode of cerebral hemorrhage. Brain magnetic resonance imaging (MRI) of the patients without microbleeds, predicted reduced risk of recurrence. This is the first report strongly associating the presence of microbleeds with the possibility of a recurrent ICH. Other factors under study did not show an apparent association with recurrent ICH probably because of the high statistical significance obtained with the presence of microbleeds. CONCLUSION: Our findings revealed that the absence of microbleeds on images is a factor that strongly predicts a reduced risk for recurrent ICH and that the detection of microbleeds on MRI performed in patients with a single hemorrhagic episode, is useful in defining further therapeutic management. These findings may benefit physicians treating stroke patients.

Prospective Study on the Efficacy of Orally Administered Tranexamic Acid and Goreisan for the Prevention of Recurrence After Chronic Subdural Hematoma Burr Hole Surgery.

OBJECTIVE: This prospective study investigated whether tranexamic acid and Goreisan effectively prevent recurrence after burr hole surgery for chronic subdural hematoma. METHODS: A total of 297 patients with chronic subdural hematoma underwent initial burr hole surgery at our hospital from April 2014 to March 2018. Of these, 206 patients (250 hematomas) consented to participate in this study. Patients were randomly divided into the nonadministration, tranexamic acid, and Goreisan groups based on age. The oral administration intervention was implemented from the day after surgery, after which there was a 3-month follow-up. Recurrence rates were measured, and head computed tomography scan was used to measure the volume of residual hematoma 1 day, 1 week, and 1, 2, and 3 months after surgery. RESULTS: A total of 193 patients (232 hematomas) were followed-up for 3 months (82 hematomas in the nonadministration group, 72 hematomas in the tranexamic acid group, and 78 hematomas in the Goreisan group). There were no significant between-group differences in demographic characteristics, current drug treatment, comorbidities, hematoma, operation side (bilateral or unilateral), preoperative hematoma volume, and recurrence rates. At 1, 2, and 3 months, the residual hematoma volume was significantly smaller in the tranexamic acid group than in the other 2 groups. CONCLUSIONS: Oral administration of tranexamic acid or Goreisan does not minimize recurrence after chronic subdural hematoma burr hole surgery; however, tranexamic acid can reduce the hematoma volume.

Trigeminal Neuralgia Caused by a Persistent Primitive Trigeminal Artery Variant and Superior Cerebellar Artery.

Trigeminal neuralgia is caused by compression of the trigeminal nerve by arteries or veins in the posterior fossa. A persistent primitive trigeminal artery variant (PPTAv) is an anomalous artery that may cause trigeminal neuralgia. A 65-year-old man presented with left facial pain. Brain magnetic resonance imaging revealed a PPTAv. Constructive interference in steady state showed that both the PPTAv and the superior cerebellar artery (SCA) compressed the trigeminal nerve. Thus, we performed microvascular decompression and the patient's symptoms improved. PPTAv is a rare anomaly in the posterior fossa that can cause trigeminal neuralgia. Dual compression of the trigeminal nerve by the SCA and PPTAv demonstrates that trigeminal neuralgia may originate from multiple sources. It is therefore important to check preoperative images to adequately treat trigeminal neuralgia.

How to Remove a Penetrating Intracranial Large Nail.

BACKGROUND: The incidence of penetrating intracranial foreign bodies is rare, and to date, not many relevant studies have been published worldwide. In particular, a nail penetrating intracranially, just near the superior sagittal sinus (SSS), is extremely rare. We treated the case of a large nail that penetrated the middle of the head and strategized its removal. CASE DESCRIPTION: A 70-year-old man had experienced headache lasting a day. Computed tomography of the brain revealed a nail penetrating the middle of his head; in particular, the tip of the nail had penetrated the right ventricle, causing a slight subarachnoid hemorrhage. Angiography showed that the nail was very close to the SSS and that the venous flow was normal. However, there was a risk of the nail penetrating through the SSS or injuring other arteries, and we removed the nail directly from the intracranial view to stop bleeding from the SSS or other vessels. Fortunately, there was no bleeding, and we washed the hole created by the nail penetration and concluded the surgery. CONCLUSIONS: Our technique is useful and safe for removing large nails penetrating the head.

[Two Case Reports of Paroxysmal Sympathetic Hyperactivity Following Craniotomy for Cerebral Hemorrhages].

Paroxysmal sympathetic hyperactivity(PSH)is a clinical condition characterized by abnormal paroxysmal surges in sympathetic nervous system activity. PSH is well known to happen after severe head injury and hypoxic encephalopathy. There are reports of cases of PSH developing after stroke, but PSH is not well recognized in the stroke field in Japan. Case 1 is a 79-year-old woman who became unconscious and suffered a large left mixed-type hemorrhage. Emergency craniotomy was performed. Two months postoperatively, she developed a high fever, tachycardia, tachypnea, and decerebrate posture. After taking clonazepam, her symptoms improved, and she was transferred to another hospital. Case 2 is a 67-year-old man with right hemiplegia, a history of thrombectomy for left M1, occlusion and left carotid artery stenting for asymptomatic left severe carotid artery stenosis performed one year previously. Five hours after right corotid artery stenting, he became restless and hemiplegic on his left side. His computed tomography showed extensive cerebral hemorrhage in the right hemisphere necessitating emergency craniotomy. About a month after surgery, he had a high fever, tachypnea, tachycardia, and decerebrate posture. Taking gabapentin improved his symptoms. Prolonged PSH may be a factor greatly impairing activities of daily living in stroke patients. It is important to diagnose and treat PSH early.

Evaluation of misdiagnosed cases of subarachnoid hemorrhage and causal factors for misdiagnosis.

BACKGROUND: Diagnosis has a major impact on the outcome of subarachnoid hemorrhage (SAH). We studied patients with SAH who were admitted to our hospital in an effort to identify ways to prevent misdiagnosis. METHODS: A total of 494 patients with SAH were admitted to the Department of Neurosurgery from 2003 through 2010. Misdiagnosis occurred in 30 patients (6.1%). We studied the symptoms and the types of misdiagnoses in these 30 patients. RESULTS: Misdiagnosis occurred 37 times in the 30 patients (6 patients were given more than 1 misdiagnosis). There were 3 types of misdiagnoses. Type 1 cases were misdiagnosed as a common cold, type 2 cases were misdiagnosed as circulatory organ disease, and type 3 cases were misdiagnosed as digestive organ disease. CONCLUSIONS: Type 1 cases were mild, and diagnosis required detailed medical history analyses. Type 2 cases were severe and were diagnosed based on electrocardiographic and echocardiographic changes characteristic of SAH. Symptoms of type 3 cases included vomiting, and diagnosis required recognition of meningeal irritation syndrome and detailed medical history analyses.

[Transcatheter arterial embolization of unresectable hepatocellular carcinoma: does selective treatment improve outcome?].

PURPOSE: To evaluate whether selective transcatheter arterial embolization (TAE) contributes to preservation of liver function and improves local control and survival in patients with hepatocellular carcinoma. MATERIALS AND METHODS: One hundred patients with hepatocellular carcinoma who underwent single or multiple TAE were retrospectively analyzed. The incidence of deterioration of liver function caused by TAE was compared between patients with Child class A disease and those having Child B/C disease. The correlation between extent of embolization and incidence of deterioration of liver function was analyzed. In addition, factors affecting deterioration of liver function after TAE were determined. Recurrence-free and overall survival rate were calculated using the Kaplan-Meier method. A Cox proportional hazard model was used to analyze prognostic factors affecting recurrence-free and overall survival. RESULTS: The incidence of deterioration of liver function in the Child B/C group (47%) was significantly higher than that in the Child A group (21%). Pretreatment Child-Pugh classification and extent of embolization were significant factors in the deterioration of liver function after TAE. Recurrence-free survival rates at 1, 2, and 3 years were 38%, 19%, and 8%, respectively. Overall survival rates at 1, 3, 5, and 7 years were 89%, 59%, 22%, and 22%, respectively. Findings of multivariate analyses of prognostic factors showed that tumor size and selectivity of TAE were significant for recurrence-free survival and the initial Child-Pugh classification was the most important factor for overall survival. CONCLUSION: Selective TAE improves local control and avoids damage to nontumorous liver tissue. The selective technique appears to be associated with a favorable outcome.

Continuous arterial infusion strategies using implanted ports.

Surgically implanted ports have been used in continuous or repetitive intra-arterial (IA) chemotherapeutic infusions for patients with multiple liver metastases from colorectal cancer. Recently, a percutaneous implantation procedure was developed, facilitating safe and less invasive IA infusions in the treatment of various disease conditions. This article focuses on the interventional techniques for percutaneous implantation of a vascular access device, consisting of an indwelling catheter and an implantable port, to perform IA infusions. Additionally, we describe details of the alteration of blood flow by coil-embolization that can be performed to obtain selective drug distribution to the target area and to avoid side effects caused by the administration of the chemotherapeutic agent into nontarget areas.
