BACKGROUND: We describe a 40-year-old Thai woman living in Japan who was transferred to Juntendo University Hospital after lung cancer was suspected. Chest X-ray showed a nodular lesion and pleural effusion in the left lung. Laboratory data showed eosinophilia. She denied having consumed raw or undercooked food at the initial interview. Microplate enzyme-linked immunosorbent assay (ELISA) for Paragonimus westermani specific immunoglobulin (Ig) G antibody was positive at a high titer, confirming the diagnosis of P. westermani infection. She was successfully treated with oral praziquantel. All primary practitioners should be aware that paragonimiasis is an important pulmonary disease that can cause nodular lesions on chest X-ray.

Bischofia javanica leaf extract exhibited inhibitory activities against hyaluronidase, collagenase, tyrosinase and urease, suggesting that it is useful as an active ingredient for functional foods and cosmeceutical products. In particular, its 50% inhibitory concentration for hyaluronidase was comparable to that of disodium cromoglycate, which is a well-known hyaluronidase inhibitor used as an anti-inflammation and anti-allergy agent. In addition, the extract also inhibited urease with the almost the same potential as acetohydroxamic acid, which is reported to suppress Helicobacter pylori-induced gastritis by inhibiting urease.

INTRODUCTION: Recently, remnant-preserving anterior cruciate ligament (ACL) reconstruction has been increasingly performed to achieve revascularization, cell proliferation, and recovery of high-quality proprioception. However, poor arthroscopic visualization makes accurate socket placement during remnant-preserving ACL reconstruction difficult. This study describes a surgical technique used to create an anatomical femoral socket with a three-dimensional (3D) fluoroscopy based navigation system during technically demanding remnant-preserving ACL reconstruction. SURGICAL TECHNIQUE: After a reference frame was attached to the femur, an intraoperative image of the distal femur was obtained, transferred to the navigation system and reconstructed into a 3D image. A navigation computer helped the surgeon visualize the entire lateral wall of the femoral notch and lateral intercondylar ridge, even when the remnant of the ruptured ACL impeded arthroscopic visualization of the bone surface. When a guide was placed, the virtual femoral tunnel overlapped the reconstructed 3D image in real time; therefore, only minimal soft tissue debridement was required. MATERIALS AND METHODS: We treated 47 patients with remnant-preserving ACL reconstruction using this system. The center of the femoral socket aperture was calculated according to the quadrant technique using 3D computed tomography imaging. RESULTS: The femoral socket locations were considered to be an anatomical footprint in accordance with previous cadaveric studies. CONCLUSIONS: The 3D fluoroscopy-based navigation can assist surgeons in creating anatomical femoral sockets during remnant-preserving ACL reconstruction.

Snapping pes syndrome is defined as a snapping sensation in the medial knee caused by pes anserinus and rarely occurs. Snapping pes syndrome after unicompartmental knee arthroplasty (UKA) has not been reported yet. We experienced two cases with this syndrome after UKA. Conservative treatment was effective in one case, while surgical excision of the gracilis tendon was necessary to relieve painful snapping in the other case. The main cause of the first case might be posteromedial overhang of the tibial tray that reached up to 5 mm. The probable cause of the second case was posteromedial overhang of the mobile bearing.
