To evaluate the intra and interobserver reproducibility of a new goniometric method for evaluating the isolated passive range of motion of the glenohumeral joint in an outpatient setting.

This is a prospective observational study on healthy subjects. The Glenohumeral ROM Assessment with Scapular Pinch (GRASP) method is a new method for assessing the isolated range of motion (ROM) of the glenohumeral joint (GH) by a single examiner with a clinical goniometer. It measures the isolated glenohumeral passive abduction (GH-AB), passive external rotation (GH-ER) and internal rotation (GH-IR) with the arm at 45º of abduction. These three GH ROM parameters were measured in both shoulders of 30 healthy volunteers (15 males/15 females, mean age41.6[SD = 10.3] years). The full shoulder passive abduction, passive external rotation and internal rotation 45º of abduction were measured by the same examiners with a goniometer for comparison. One examiner made two evaluations and a second examiner made a third one. The primary outcome was the intra- and interobserver reproducibility of the measurements assessed with intraclass correlation coefficients (ICC) and the Bland-Altman plot.

The intra-observer ICC for isolated glenohumeral ROM were 0.84 ± 0.07 for GH-ABD, 0.63 ± 0.09 for GH-ER, and 0.61 ± 0.14 for GH-IR. The inter-observer ICC for isolated glenohumeral ROM were 0.86 ± 0.06 for GH-ABD, 0.68 ± 0.12 for GH-ER, and 0.62 ± 0.14 for GH-IR. These results were similar to those obtained for full shoulder ROM assessment with a goniometer.

The GRASP method is reproducible for quick assessment of isolated glenohumeral ROM.

Four-rod instrumentation and interbody fusion may reduce mechanical complications in degenerative scoliosis surgery compared to 2-rod instrumentation. The purpose was to compare clinical results, sagittal alignment and mechanical complications with both techniques.

Full spine radiographs were analysed in 97 patients instrumented to the pelvis 58 2-rod constructs (2R) and 39 4-rod constructs (4R). Clinical scores (VAS, ODI, SRS-22, EQ-5D-3L) were assessed preoperatively, at 3 months, 1 year and last follow-up (average 4.2 years). Radiographic measurements were thoracic kyphosis, lumbar lordosis, spinopelvic parameters, segmental lordosis distribution. The incidence of non-union and PJK were investigated.

All clinical scores improved significantly in both groups between preoperative and last follow-up. In the 2R-group, lumbar lordosis increased to 52.8° postoperatively and decreased to 47.0° at follow-up (p = 0.008). In the 4R-group, lumbar lordosis increased from 46.4 to 52.5° postoperatively and remained at 53.4° at follow-up. PF-562271 FAK inhibitor There were 8 (13.8%) PJK in the 2R-group versus 6 (15.4%) in the 4R-group, with a mismatch between lumbar apex and theoretic lumbar shape according to pelvic incidence. Non-union requiring revision surgery occurred on average at 26.9 months in 28 patients (48.3%) of the 2R-group. No rod fracture was diagnosed in the 4R-group.

Multi-level interbody fusion combined with 4-rod instrumentation decreased risk for non-union and revision surgery compared to select interbody fusion and 2-rod instrumentation. The role of additional rods on load sharing still needs to be determined when multiple cages are used. Despite revision surgery in the 2R group, final clinical outcomes were similar in both groups.

III.Trichoblastic carcinoma is a rare neoplasm thought to arise from malignant degeneration of benign follicular tumors. Its clinical features, optimal treatment, and outcomes remain largely unknown. We performed a comprehensive review of the existing trichoblastic carcinoma literature. PubMed and Google Scholar were searched for keywords related to trichoblastic carcinoma, and additional articles were found in reference lists. Cases with a histopathologic diagnosis of trichoblastic carcinoma were summarized. A total of 93 cases have been described, all in case reports or case series. The average age was 65, with 66.7% of cases in males. A minority of patients had familial tumor syndromes or a history of radiation at the site, and only one was reported to be immunosuppressed. The most common site was the face (48.4%), and the majority developed de novo (87.1%). The clinical presentation was highly variable. Although most cases (82.8%) were successfully treated with surgery alone, a subset of patients had more aggressive disease including local progression or recurrence in five cases, nodal metastases in five cases, and distant metastases in three cases. Trichoblastic carcinoma is a rare malignancy with the potential for aggressive behavior. Further research is needed to better characterize this neoplasm.

We analyzed the synthetic full-length transcript promoter of Blueberry red ringspot virus (BRRV) and developed two chimeric promoters (MBR3 and FBR3). Transcriptional activities of these chimeric promoters were found equivalent to that of the CaMV35S

promoter. Chimeric promoters driven plant-derived PaDef protein showed high antimicrobial activities against several pathogens. Blueberry red ringspot virus (BRRV) is a pararetrovirus under the genus, Soymovirus belongs to the Caulimoviridae family. We have made a synthetic version of the BRRV-Flt promoter and analyzed its activity in detail. A 372bp promoter fragment BR3 (- 212 to + 160) showed the strongest transcriptional activity compared with other fragments in both transient and transgenic assays; its activity was found near equivalent to that of the CaMV35S promoter. We constructed two chimeric promoters; MBR3 and FBR3 by fusing the UASs (Upstream activation sequences) of Mirabilis mosaic virus (MUAS; - 297 to - 38; 335bp) and Figwort mosaic virus (FUAul substitutes for the widely used CaMV35S2 promoter in plant biology.

Cord lipomas can clinically resemble groin hernias and missed cord lipomas can potentially result in persistent symptoms. However, no international guideline exists concerning the management of cord lipomas found during inguinal hernia surgery. This study aimed to gain insight into how surgeons typically manage cord lipomas found during inguinal hernia surgery.

A questionnaire was sent to all general surgeons in Denmark performing unsupervised laparoscopic inguinal hernia repair and Lichtenstein repair. The survey contained questions about demographic details and questions about how surgeons would handle cord lipomas. The questionnaire was created by the research team and face-validated on general surgeons.

A total of 58 surgeons (60%) responded to the questionnaire. The majority agreed that cord lipomas should not be left untouched. During laparoscopic repairs, 53% of the surgeons recommended that cord lipomas should be resected and removed if the anatomical circumstances allowed it. During Lichtenstein repair, the surgeons recommended that cord lipomas should always be resected and removed (49%) or that resection should depend on the size of the lipoma (44%).
