Review Case Reports
Tuberculosis combined with Burkitt lymphoma in a kidney transplant recipient: A case report and literature review.
Tuberculosis (TB) and post-transplant lymphoproliferative disorder are serious complications affecting the long-term survival of kidney transplant recipients (KTRs). Both of complications have overlapping clinical symptoms, signs, and high similar imaging presentation, which make early clinical diagnosis challenging. In this paper, we reported a rare case of post-transplant pulmonary TB combined with Burkitt lymphoma (BL) in KTR. ⋯ Therefore, in organ transplant patients, who present with multiple nodules and normal tumor markers, they should be alerted to the possibility of concurrent TB and post-transplant lymphoproliferative disorder, and perfect tests such as Epstein-Barr virus, β2-microglobulin, lactate dehydrogenase, γ-interferon release test and Xpert Mycobacterium TB/rifampicin test and perform early lesion site biopsy to clarify the diagnosis with a view to improving the prognosis.

Obesity is associated with cervicalgia and low back pain (LBP), but the specific role and how to reduce the risk of neck pain and low back pain are not clear. The Mendelian randomization analysis was used to investigate the causal relationship between obesity and cervicalgia and LBP, as well as the effect of possible mediating factors. ⋯ Ranked by mediated proportions of selected mediators, the largest causal mediator from BMI and WC to cervicalgia was educational level (38.20%, 38.20%), followed by HPW (22.90%, 24.70%), and MD (9.20%, 17.90%); However, the largest causal mediator from BMI and WC to LBP was LSB (55.10%, 50.10%), followed by educational level (46.40%, 40.20%), HPW (28.30%, 20.90%), smoking initiation (26.60%, 32.30%), alcohol intake frequency (20.40%, 6.90%), and MD (10.00%, 11.40%). For obese individuals, avoiding HPW and maintaining a stable mood may be an effective approach to prevent cervicalgia; Additionally, reducing LSB, avoiding HPW, quitting smoking and drinking, and maintaining a stable mood may be an effective approach to prevent LBP.

Human epidermal growth factor receptor 2 (HER2)-targeting therapies have become crucial in the management of HER2-positive breast cancer. Trastuzumab emtansine (T-DM1) is a microtubule inhibitor and HER2-targeted antibody conjugate. T-DM1 resistance is most likely influenced by factors involved in the biological mechanisms of T-DM1 action. ⋯ The association between statin use and PFS did not reach statistical significance (34.7 vs 9.9 months, P = .159). Multivariate Cox regression analysis showed that better performance status (hormone receptor [HR]: 0.30, 95% CI: 0.13-0.71, P = .006), use of trastuzumab plus pertuzumab prior to T-DM1 (HR: 0.37, 95% CI: 0.18-0.76, P = .007) and use of statins with T-DM1 (HR: 0.29, 95% CI: 0.12-0.70, P = .006) were independent factors that prolong OS duration. Our study showed that T-DM1 is more effective at treating HER2-positive breast cancer in people who receive statins concurrently with T-DM1 than those who do not.

Pyomyositis is a microbial infection of the muscles and contributes to local abscess formation. Staphylococcus aureus frequently causes pyomyositis; however, transient bacteremia hinders positive blood cultures and needle aspiration does not yield pus, especially at the early disease stage. Therefore, identifying the pathogen is challenging, even if bacterial pyomyositis is suspected. Herein, we report a case of primary pyomyositis in an immunocompetent individual, with the identification of S aureus by repeated blood cultures. ⋯ The pyomyositis-causing pathogen can be identified by repeated blood cultures even when pyomyositis is non-purulent but suspected based on physical examination, ultrasonography, and magnetic resonance imaging findings.

Case Reports
The role of the absence of Hyrtl's anastomosis in monochorionic pregnancy: Friend or foe?: A case report.
Hyrtl's anastomosis, an intra-arterial shunt, plays a protective role when the placental territories supplied by the umbilical arteries are different in size. Its absence is associated with an increased risk of poor outcomes in singleton pregnancy. However, the literature and studies on the effect of absent Hyrtl's anastomosis in twin placentas are rare. ⋯ The absence of Hyrtl's anastomosis in our case seemed to show a favorable effect, representing a finding of opposite effects in monochorionic placentas compared with singleton placentas.
