SUMMARY An unusual case of peripheral hypoglossal nerve palsy, caused by lateral position of the external carotid artery and an abnormally high carotid bifurcation is reported. Improvement followed ligation and cutting of the external carotid artery at its origin. Stroke Vol 15, No 4, 1984 VARIATIONS AND ANOMALIES are common at the bifurcation of the external and internal carotid arteries.1 Lateral position of the external carotid artery 2 " 6 formerly considered extremely rare, has recently been found to be more common.7 8 However, there are few reports, that this condition causes neurological signs.1 In this paper, a case of peripheral hypoglossal nerve palsy caused by lateral position of the external carotid artery and a carotid high bifurcation is presented.Case Report A 49-year-old man was admitted because of tongue deviation and dysarthria on December 8, 1980. At age 42, his blood pressure was found to be high and antihypertensive drugs were presented. He had felt throbbing pains in the occipital region beginning November 10, 1980, but these pains became intense from midday of November 21. At that time he visited a neurosurgical clinic, but no abnormalities could be found. On the morning of November 22, eating became difficult, and movement of the tongue was impeded, making speech inarticulate.Tongue deviation to the right and atrophy and fasciculation of the right lingual muscle were observed ( fig. 1). Tactile sensibility and taste sensation of the tongue were normal, and no abnormality of other cranial nerves was observed. There were no other abnormalities on neurological examination. Homer's sign was not presented and no bruit was heard in the neck. A diagnosis of peripheral hypoglossal nerve palsy with suspected hypoglossal neurinoma was made.A CT scan demonstrated no abnormality related to the right hypoglossal palsy. Right jugular venography revealed good filling by contrast medium and no abnormal findings. Tomography of the hypoglossal ca- nals, was normal. Bilateral carotid angiography and bilateral vertebral angiography were performed. No abnormalities were observed in the vertebral angiogram, except conspicuous elongation of the basilar artery. In the right carotid angiogram, marked lateral displacement of the right external carotid artery was noticed and the bifurcation of the external and internal carotid arteries was abnormally high (upper margin of the C 2 vertebra); there was conspicuous kinking and elongation of the external and internal carotid arteries and, in particular, prominent dilatation of the proximal portions of both arteries. In the lateral view of the angiogram, a loop-like elongation was observed 3.5 cm distal to the bifurcation ( fig. 2). In the left carotid angiogram, as in that of right side, the bifurcation was at a high level (center of C 2 vertebra) and elongation was conspicuous, but a lateral position of the external carotid artery was not seen.From this examination, the possibility of hypoglossal neurinoma was excluded and the following two mechanical processes wer...

An intramuscular injection (IMI) is an injection given directly into the central area of a specific muscle. Certain medicines need to be administered by the gluteal route for these to be effective. The aim of this study was to determine the influence of body mass index (BMI), subcutaneous fat, and muscular thickness of the dorsogluteal IMI site among healthy Japanese women. There were 39 healthy female subjects who volunteered and met the criteria. Their ages ranged from 40s to 60s (50.82 ± 6.04). With the data collected using the B-mode ultrasound images of the dorsogluteal site, it was found that the distance from the epidermis to the under-fascia (DEUF) of the gluteus maximus was dissimilar between the subject's right and left buttocks. It was found that the distance from the epidermis to the iliac bone (DEI) was significantly more on the right than on the left buttocks. In the case of an adult Japanese woman with a BMI of 21 or more, the DEUF of the gluteus medius was found to be about 30 mm, and the DEI was approximately 50 mm or more. Based on these findings, it is recommended that a needle length of 38 mm (1.5 inches) can be safely used to administer IMIs to the gluteus medius muscle to effectively and efficiently deliver medications through the IMI route.

Long Acting Injectable (LAI) medications for patients with schizophrenia is commonly administered to relieve their symptoms. Through shared decision-making and clinical evidence-based, psychiatrists should systematically offer LAIs to all patients requiring long-term antipsychotic treatment as a first-line treatment. Gluteal intramuscular (IM) injection requires accurate insertion of needles into the specific muscle area, often the outer upper quadrant of the buttocks, in order to achieve the required blood concentration. The purposes of this study were to compare the "Distance from the Epidermis to the Under-Fascia (DEUF)" and "Distance from the Epidermis to the Iliac Bone (DEB)" of the buttocks IM injection sites at the dorsogluteal and ventrogluteal sites among healthy Japanese volunteer subjects, and to identify the optimal insertion injection needle length. The DEUF and DEB at the gluteal regions were measured by ultrasonography. Welch's one-way analysis of variance was used to compare the DEUF and the DEB at the gluteal IM injection regions. There was no statistically significant difference observed between the right and left mean values of DEUF for Hochstetter and Clark's point at the ventrogluteal sites, and the Four and Three-way split or Double Cross point at the dorsogluteal sites. However in the DEB, the Hochstetter's point (P < 0.01) at ventrogluteal site on the right side, and Clark's point (P < 0.05) were significantly shorter than the Double Cross point at dorsogluteal sites (F = 4.38). The left buttocks S. Masuda et al. 204 Hochstetter's point was significantly shorter than the Double Cross point (F = 4.38, P < 0.01). These results, however, did not establish a statistically significant difference in the DEUF among injection sites. It was considered that the difference in the DEB depended on muscle volume and thickness in the gluteal injection sites.

This study was conducted with six patients with schizophrenia, four of whom received the atypical antipsychotic risperidone long-acting injectable (RLAI), and two patients receiving the typical depot injection (TDI). The purpose of this study was to determine the location (gluteus medius or maximus; deltoid muscles) and diffusion of typical and atypical antipsychotic medications administered intramuscularly using ultrasonography. When using the standardized depth of needle insertion, in some cases, the drug was injected into the gluteus maximus instead of the gluteus medius. Similarly, in some cases the TDI was not visible in the ultrasonographic images until sixteen days after the injection. This verifies how hard the injection site becomes when microspheres of RLAI is injected as compared to other muscle areas. These results confirmed that the gluteus muscle structure was the ideal muscle for depot injection as evidenced by the injection solution being dispersed and rendered not visible immediately after intramuscular injection (IM). With the use of ultrasonography, injection sites and drug dispersions were evaluated under a direct visual guidance, suggesting that ultrasonography is a useful method for establishing evidence for determining correct insertion of IM injection, diffusion of medications, and the effective administration of IM injections.

Basilar artery perforator aneurysms (BAPAs) are a rare cause of subarachnoid hemorrhage (SAH), and the natural history is still unknown. Herein, we report a case of ruptured BAPA that appeared during the observation period and then spontaneously disappeared; we have also conducted a review of the literature and performed an analysis based on the type of management. This case of BAPA had a unique course, and our observations may help establish a treatment strategy. A 60-year-old man presented with acute diffuse SAH, World Federation of Neurosurgical Societies (WFNS) Grade II and Fisher Grade 3. Initial three-dimensional digital subtraction angiography (DSA) did not show the source of the hemorrhage. DSA performed on day 39 showed a BAPA with a diameter of 3 mm at the posterior surface of the upper third of the basilar artery. Conservative treatment was chosen. DSA performed on day 64 showed complete resolution of the aneurysm. BAPAs are likely pseudoaneurysms, and not saccular aneurysms, caused due to dissection of basilar perforator arteries . BAPAs are often not recognized on initial imaging, and hence, it is necessary to repeat the DSA examination. Considering the relatively high rate of spontaneous resolution, we chose conservative management. When BAPAs enlarge or do not disappear after conservative treatment, additional therapy such as multiple stents should be considered.

The awareness of care provided by stroke care unit (SCU) nurses in Japan to patients with an acute cerebrovascular accident (CVA) and the characteristic differences in their actual nursing practice were evaluated. A cross-sectional web-based questionnaire survey was administered to 1040 SCU nurses. Data collection and reporting procedures followed the STROBE Statement Checklist for cross-sectional studies. Exploratory factor analysis, using 52 observation items, identified eight factors with a factor loading > 0.4. For all factors, the actual practice was significantly lower than the awareness of the importance of nursing care for patients with acute CVA. Awareness and actual practice of recognition of patients’ physical changes (RPPCs) were high. The actual practice of RPPCs and preventing the worsening of acute stroke and related symptoms varied, depending on years of experience in acute phase stroke care. RPPCs in actual practice had a significantly higher score among certified nurses or certified nurse specialists. Their awareness of the importance of collaborating with therapists was low. On-the-job training can improve nurses’ competence and prevent worsening conditions in patients with CVA. An emphasis on enhancing practice experience toward patients with acute CVA and facilitating the deployment of certified nurses in SCUs can improve nursing care practice.
