Repair of a retracted anterior L‐shaped rotator cuff tear is challenging because of the lack of mobilization of the torn tendon and destruction of the rotator cable. Restoring the anterior rotator cable decreases gap formation of the repaired tendon, leading to maintenance of the repair integrity of the anterior supraspinatus tendon. This Technical Note introduces the surgical technique of anterior cable reconstruction using the proximal biceps tendon for a retracted anterior L‐shaped rotator cuff tear.

Female pattern hair loss (FPHL), the most common cause of alopecia in adult women, is classified into two subtypes: early onset and late onset (or postmenopausal). Little is known about the clinical features and genetic characteristics of early onset female pattern hair loss (eFPHL). To investigate the clinical features and genetic characteristics of eFPHL. Patients with eFPHL and controls without eFPHL were prospectively recruited. The demographic and clinical features were collected. Single nucleotide polymorphisms (SNPs) located around the selected 30 candidate genes potentially associated with eFPHL were evaluated. eFPHL patients (n = 63) manifested a decreased hair shaft density and cross-sectional area of the hair shaft compared to the control group (n = 341). eFPHL is associated with androgen-related features, including scalp greasiness, folliculitis, hirsutism, and polycystic ovary syndrome. Scalp pain and itching have been reported more frequently in patients with eFPHL. Forty-nine SNPs located around PPARGC1A, ABCC4, CYP11B2, FSHB, and CYP19A1 were found to be significant for eFPHL, including two PPARGC1A-associated SNPs: rs186530605 and rs192713767 (p = 3.94 × 10^-11). This study provided clinical features and genetic variants for eFPHL, which could provide insight into the underlying pathologic etiology. Considering the limited number of patients, a large-scale study is required in the future.

Heartworm (HW) disease, caused by Dirofilaria immitis, is a life-threatening ailment in dogs. HW disrupts blood flow and decreases cardiac output (CO). The accurate monitoring of CO during HW extraction is pivotal for patient survival and overall health. Objective: This study aimed to assess the efficacy of using impedance cardiography (ICG) as a non-invasive approach for monitoring CO during interventional HW extraction. Methods: Two cases of HW infections were treated via surgical extraction. The CO and mean arterial pressure (MAP) were monitored using the ICG technique during the anesthesia stabilization, extraction process, and post-extraction phases. Results: In Case 1, the CO increased by 115% post-procedure, and in Case 2, the CO increased by 116%. In contrast, the MAP varied between the two cases. The ICG method provided real-time CO data without major disruptions during the extraction surgery. Conclusion: The ICG technique for CO monitoring during interventional HW extractions is effective.

Recently, the field of regenerative medicine has made great strides in the development of new treatments for various organ dysfunctions. One of the most promising new approaches is the use of three‐dimensional (3D) printing and autologous tissues. In this study, we evaluated the safety of a 3D‐printed autologous omentum patch to kidneys using large animals. A total of seven micropigs underwent transplantation of the 3D‐printed autologous omentum patch. Twelve weeks after transplantation, the safety was evaluated by measuring body weight, blood, and the renal resistive index. In addition, biopsy samples were histologically analyzed. The results showed no surgical complications, renal functional hematological changes, or inflammatory responses. Therefore, this study provides important insights into direct therapy to kidneys with a 3D‐printed patch made of autologous tissue. Furthermore, it has the potential for the development of new therapies for various organ dysfunction.
