Carpal tunnel syndrome (CTS) is a common form of hand mononeuropathy that is typi-cally caused by median nerve compression. Although it is often idiopathic, CTS can also result from various conditions, including space-occupying lesions. Tumoral calcinosis, a rare condition characterized by periarticular deposition of calcified masses, is an un-common cause of secondary CTS. We present a case of a 78-year-old woman with idio-pathic tumoral calcinosis that caused secondary CTS. Despite conservative treatments, her symptoms persisted, and diagnostic imaging, including radiographs, computed to-mography, and magnetic resonance imaging, revealed a calcified mass in the carpal tun-nel. A surgical intervention involving carpal tunnel release and excisional biopsy con-firmed the diagnosis of tumoral calcinosis. Postoperatively, the patient showed complete resolution of symptoms, with no recurrence on follow-up radiographs. This case high-lights the importance of considering space-occupying lesions, such as tumoral calcinosis, as a rare but treatable cause of secondary CTS.

Various acupuncture clinical trials have been conducted on migraine; however, the conclusions remain controversial especially when acupuncture was compared with sham acupuncture. Sham acupuncture is sometimes performed at the same acupuncture points used for verum acupuncture despite the evidence on acupuncture point specificity. Four databases were searched for sham acupuncture or waiting list-controlled acupuncture trials for migraine on December 25, 2023. Sham acupuncture was classified according to the needling points: sham acupuncture therapy at verum points (SATV) or at sham points (SATS). Network meta-analysis was performed based on the frequentist framework for headache pain intensity and response rate. A total of 18 studies involving 1936 participants were analyzed. Headache pain intensity and response rate were significantly improved in verum acupuncture compared with SATS. However, there was no significant difference between SATV and verum acupuncture. When comparing SATS and SATV, there was no significant difference in headache pain intensity and response rate; however, the results were in favor of SATV. The effect of the risk of bias on the certainty of evidence between verum and sham acupunctures was judged to be generally low. SATV should not be misused as a placebo control to evaluate the efficacy of acupuncture.

BACKGROUND/OBJECTIVES: Recently, herbal medicines have gained attention for the treatment of benign prostatic hyperplasia (BPH), a common disease in elderly men. In this study, we aimed to determine the effect of ethanol extract of Asparagi radix (EAR), which is traditionally used to treat various diseases, on BPH development using a testosteroneinduced BPH model.MATERIALS/METHODS: Testosterone propionate (TP)-treated Sprague–Dawley rats were used to establish a BPH model in vivo. EAR was orally administered along with TP, and finasteride was used as a positive control. All rats were sacrificed at the end of the experiment, and pathological changes in the prostate tissue and levels of key biomarkers associated with BPH pathogenesis were assessed. RESULTS: Oral administration of EAR significantly inhibited TP-induced BPH by reducing the prostate weight, lumen size, and epithelial thickness in a concentration-dependent manner. EAR also significantly abrogated the expression of 5α-reductase type 2 (SRD5A2), proliferating cell nuclear antigen, and prostate-specific antigen (PSA) induced by TP.Additionally, serum levels of testosterone, dihydrotestosterone, and PSA were elevated in the TP-induced group but decreased in the EAR-treated group. EAR also decreased the expression levels of the androgen receptor (AR) and its coactivators in TP-induced BPH model rats. CONCLUSION Our findings revealed that EAR protected against BPH by inhibiting 5α-reductase activity and AR signaling pathway, suggesting its potential for BPH treatment.

The incidence of anaplastic large cell lymphoma is 0.25 cases per 100,000 people. It usually causes lymphadenopathy and B symptoms; however, diverse cutaneous manifestations can also be observed. We report a rare case of anaplastic large cell lymphoma of the scalp, which presented similarly to a ruptured epidermal cyst. A 77-year-old woman visited the outpatient clinic complaining of scalp masses that had appeared 2 months before. One week before her visit, she had undergone incision and drainage at a local clinic but showed no improvement. Before surgery, facial magnetic resonance imaging revealed two suspicious ruptured cystic masses. Surgical excision was performed with a 1-cm free margin from the soft mass. Histopathology confirmed anaplastic lymphoma kinase-negative anaplastic large cell lymphoma. After wide excision and skin grafting for wound reconstruction, followed by consultation with a hemato-oncologist and radiation oncologist, chemotherapy was planned to prevent recurrence. Differentiating anaplastic lymphoma kinase-negative anaplastic large cell lymphoma of the scalp from a ruptured epidermal cyst-like mass proved challenging. We recommend considering the possibility of anaplastic large cell lymphoma if an epidermal cyst-like mass does not respond to antibiotics or conventional dressing, as illustrated by our rare case.
