Anatomically, it seems to be made up of three different sets of fibers. The three anatomical portions in which the deltoid muscle are typically divided into the anterior (clavicular), the mean (acromial), and the posterior (spinal). Different variations of the deltoid muscle have been described in the literature. The analysis and knowledge of these anomalies are essential for surgeons and anatomists. Methods: A total of 21 specimens (12 women and 9 men) were used with a 10% formaldehyde solution. All specimens were dissected bilaterally (the classical dissection methodology was used). Results: In one corpse, an additional bilateral belly of the deltoid muscle was found. It was observed that this additional muscular belly was related to the fascial tissue of the deltoid muscle and its muscle fibers take origin from the middle third of the inferomedial bands of infraspinatus fascia. In addition, the belly attaches to the posterior belly of the deltoid muscle. The deltoid muscle and the additional belly were innervated by the axillar nerve, which is a lateral terminal bouquet of the posterior fascicle of the brachial plexus. Conclusions: This new variation of the deltoid muscle must be considered by surgeons, as well as abnormal conditions in terms of compartment syndrome involving the shoulder. Therefore, consideration of this variant is necessary for the correct diagnosis and treatment of trauma or other shoulder pathology that may be refractory to standard treatments.","PeriodicalId":7888,"journal":{"name":"Anatomia","volume":"292 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76482324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Recognizing and Distinguishing the Phenomenon Referred to as Meningioma","authors":"B. Rothschild","doi":"10.3390/anatomia1010011","DOIUrl":"https://doi.org/10.3390/anatomia1010011","url":null,"abstract":"Background: The reliability of a recent review of meningiomas in the archeologic record was difficult to assess, given the inverted sex ratio of the report and other contents apparently at variance with anatomical/medical findings in scientifically identified cases. It therefore seemed appropriate to reexamine the nature of meningiomas and derive improve criteria for their recognition in the archeologic record and distinguish them from hemangiomas and bone marrow hyperplasia (recognized in the form of porotic hyperostosis). Methods: Medically documented cases of meningiomas were examined to establish a macroscopic standard distinguishing them. Alleged cases in the archeologic record were examined for conformity with those criteria. Results: An en face pattern of uniform mesh with contained whorls appears pathognomonic for meningiomas. This contrasts with the non-uniform marrow expansion displacement of trabeculae in porotic hyperostosis and non-uniform vascular displacement of trabeculae in hemangiomas. Reassessment of past attributions revealed few cases of meningiomas that could be confidently diagnosed. Those identified have sex ratios parsimonious with medical literature reports. Conclusions: Criteria suggested for identifying meningiomas permit distinguishing from hemangiomas, bone marrow hyperplasia (porotic hyperostosis) and from the macroscopically observable surface spicules characteristic of osteosarcomas. Examination for fulfillment of criteria for meningiomas and hemangiomas seems to provide a picture (including sex ratios) mirroring that of the clinical literature, concluding that Cook and Danforth’s disparate ratios were related to less fastidious case selection. Additionally, confidence in recognizing porotic hyperostosis may be compromised because of apparent similar macroscopic alterations to those seen with hemangiomas.","PeriodicalId":7888,"journal":{"name":"Anatomia","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73908172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overlapping distribution patterns for both substances were observed in many brainstem regions, suggesting that interactions between them may occur in the reticular formation, nucleus ambiguus or laterodorsal tegmental nucleus. Colocalization of the two substances in the same cell bodies was only observed in restricted areas, such as the nucleus of the solitary tract, reticular formation and nucleus ambiguus. In addition, in several regions, an apparent high innervation of the peptidergic fibers on cholinergic neurons has been observed. The results suggest that chemospecific interactions could be crucial for the control of specific cardiorespiratory and/or digestive functions in alpacas. These interactions may represent brain-adaptive mechanisms to particular environments and have a potential therapeutic use in respiratory disorders.","PeriodicalId":7888,"journal":{"name":"Anatomia","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88334649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Cincinnati MR Imaging of NeuroDevelopment (C-MIND) dataset was used to examine the relationship between age and hippocampal dentation in 90 healthy children, age < 1 to 18 years old, using T1-weighted MPRAGE scans. Hippocampal dentation was assessed by counting the number of dentes for the left and right hippocampi. Participants had slightly more left than right hippocampal dentes, on average. Dentation did not differ significantly between males and females. Correlational analyses revealed that the numbers of left, right, and total dentes were positively associated with age in this sample. Interestingly, these data highlight the wide variability of dentation in older age groups. While younger children tended to have absent or few dentes, a range of dentation was present in older children and adolescents (ranging from absent to numerous, bilaterally). This is consistent with previous research in a healthy adult cohort, where a range of dentation was also observed.

We identified two regions (lips and eyelids) with vellus hairs that did not show an arrector pili muscle. In the eyelids, the hairs are rather small and short; in the lips, the vellus hairs were surrounded by striated muscle fibers from the orbicularis oris muscle. In all other regions (frontal region, forehead, cheek, chin), the vellus hairs contained an arrector pili muscle with comparable morphology. Only in the chin region, where additional striated muscles from the face muscles were present, the arrector pili muscles were thinner.

Seventy–six patients (49 men, 27 women) received CT scans for focus search. Adrenal glands were analyzed by means of three different methods: subjective region of interest (ROI) measurement, organ segmentation and histogram analysis using semi-automated software. Univariate analyses with multiple testing thresholds and receiver operating characteristic curves were performed. Clinical endpoints were 8-days, 28-days and 6-months mortality. Forty-four CT scans were analyzed (ground truth: patients with no sepsis: n = 6; patients with sepsis: n = 15; patients in septic shock: n = 21). Left adrenal gland (LAG) values were analyzed and compared, as data variation was lower than in the right adrenal glands. In patients with septic conditions, the combination of high LAG and Inferior Vena Cava (IVC) density values was highly specific for septic shock with all three methods. Only segmentation values were significantly different between the sepsis and septic shock groups after confounder correction (p = 0.048). Total adrenal gland volume was 20% higher in the septic shock patients while a relatively small LAG volume within the septic shock subgroup was associated with higher mortality at day 8 (AUC = 0.8; p = 0.006) and at 6 months (AUC = 0.7; p = 0.035). However, time-consuming density analysis methods assessing adrenal glands do not provide additional diagnostic value in patients with septic conditions. The combination of high LAG and IVC attenuation values seems to be highly specific for septic shock, regardless of the analysis type.
