Applying the inclusion and exclusion criteria, 29 articles were finally selected.Results: A number of asymmetries have been recorded related to the size of the cortex between the two hemispheres, the number of Heschl's gyri and Heschl's gyrus surface variations, the distribution of gray and white matter, and the surface and size of the secondary auditory cortex. Reviews, and all prospective and retrospective studies, as well as case reports, were eligible for this review.Discussion: Variations were found amongst patients of reduced auditory ability and the non-hearing impaired, musicians, amateur musicians, and non-musicians, right and left-handed people, men and women, and people with high and low pitch perception ability. Furthermore, variations were detected in people with dyslexia and learning disabilities.Conclusion: A significant number of anatomical variations of the auditory cortex have been recorded, and closer research will contribute to our comprehension of the origin of some discrepancies in everyday clinical practice.","PeriodicalId":38313,"journal":{"name":"Acta medica academica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143804421","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}

After 16 years, he required alloHSCT for acute myeloid leukemia (AML), with the same sibling serving as the donor for both transplants. HLA was a 50% match. Post-alloHSCT, immunosuppressive therapy was discontinued, and the renal allograft function remained stable. The patient later developed severe complications and succumbed to infection. Insights into the precise tolerance mechanisms were limited because laboratory evaluation for chimerism was not performed.Conclusion: There is potential for immunosuppressive-free renal allograft function after alloHSCT. This case underscores the significant risk of infection-related mortality. To achieve the best outcome, rigorous patient selection, tailored conditioning regimens, robust infection prevention strategies, and the possibility of combined transplantation for carefully selected patients are needed.","PeriodicalId":38313,"journal":{"name":"Acta medica academica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143732162","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}

A total of 13,760 ultrasound examinations were performed, using a Toshiba Xario 100 ultrasound machine with a 12 MHz linear probe. Patients were divided into premenopausal and postmenopausal groups, excluding patients with symptoms and those with previous breast cancer surgery. The images were stored using the Institution's Pictures Activation and Communication System.Results: BI-RADS category 3 findings accounted for 27% of all ultrasound examinations (N=3.715). Of these, 9.02% (N=335) underwent recommended short-term follow-up. Malignancy was identified in 1.49% of these cases (N=5), with an average tumor size of 13.6 mm at detection. The malignancy rate did not differ significantly between premenopausal and postmenopausal patients (P=0.412). The overall diagnostic yield for malignancy in BI-RADS 3 findings was low, but clinically significant.Conclusion: While the malignancy rate for BI-RADS category 3 findings is low (1.49%), careful monitoring and adherence to follow-up guideline are essential to balance early detection with avoidance of unnecessary biopsies and associated costs.","PeriodicalId":38313,"journal":{"name":"Acta medica academica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143504668","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 first patient also suffered from alcohol use disorder (AUD) and underwent thoracoscopic pleural biopsy. The second patient was scheduled for laparoscopic hemicolectomy. Due to the unavailability of ultrasound and excessive choreic movements, locoregional anesthetic techniques were not feasible. Both patients were successfully managed using similar opioid-sparing, multimodal anesthetic-analgesic strategies, and had uncomplicated postoperative courses. In both patients, a dexmedetomidine infusion was used, and both reported a brief amelioration of their chorea postoperatively.Conclusion: This is the first reported case of a patient with Huntington's disease with concurrent AUD undergoing general anesthesia using modern, opioid-sparing, multimodal, anesthetic-analgesic strategies. Even when the advantages of locoregional anesthesia are not available, HD patients can be safely and effectively treated using modern anesthetic methods that minimize opioid use and its associated side effects.","PeriodicalId":38313,"journal":{"name":"Acta medica academica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143400301","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}

Cytology, FC, and subsequent surgical pathology diagnoses were correlated.Results: Of 821 FNAs, 154 (19%) met selection criteria. Reactive lymph nodes accounted for 43% (67/154), with most diagnosed as 'negative for malignancy,' except one 'atypical' (ATY) case. Lymphoma was confirmed in 57% (87/154) of cases, categorized as ATY (55%), suspicious for lymphoma (SFM) (36%), or positive for lymphoma (PFM) (9%). Lymphoma patients were older (median 66 vs. 46 years). Thyroid and salivary gland lymphomas typically indicated systemic involvement, except for two cases of marginal zone lymphoma (MZL) in patients with Sjögren syndrome. FC alone had a sensitivity of 67.5% for detecting lymphoma, but when combined with cytology, the sensitivity increased to 100%. The combined approach maintained a specificity of 98%. More abnormal clonal cells were identified by FC in PFM cases compared to SFM or ATY cases (P=0.004). Cytologic atypia with negative FC occurred in 29% of lymphomas, including Hodgkin and diffuse large B-cell lymphoma (DLBCL).Conclusion: Lymphomas presenting as neck masses are diverse, with FNA playing a key diagnostic role. Cytologic atypia and FC complement each other, as some cases show minimal atypia but positive FC, while others show significant atypia with negative FC.","PeriodicalId":38313,"journal":{"name":"Acta medica academica","volume":" ","pages":"274-285"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11831544/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142802450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nerve displays diverse paths and trajectories, leading to deviations from the commonly accepted anatomical description. Additionally, we identified variations in the division point of the obturator nerve and the resulting innervation patterns that it provides for muscles, joints, and skin. More precisely, we discovered differences regarding the path, the source and the level of composition. Moreover, the muscles innervated by the obturator nerve's anterior branch and posterior branch may vary. Furthermore, variations were observed in the innervation of both the skin and joints. CONCLUSION: Our research demonstrates that the obturator nerve is susceptible to many forms of variations.
