Case Reports
Recurrent osteoid osteoma of the index proximal phalanx: A case report with a new resection technique.
Osteoid osteoma is a relatively common benign bone-forming lesion that often occurs in young adults with a predilection for the lower limbs and spine. It is characterized by the formation of osteoid tissue, a precursor to bone, and can cause pain and restricted mobility in affected areas. Osteoid osteoma of the hand and fingers is rare, thus representing a diagnostic challenge. A written informed consent was provided from the patient's father for the publication and sharing all images and clinical data concerning the patient. ⋯ Overall, this case highlights the challenges of diagnosing and treating osteoid osteoma in the hands and fingers. Further research is needed to better understand the underlying causes, potential risk factors, and optimal treatment for osteoid osteoma recurrence.

In the last few years, treatment of head and neck squamous cell carcinoma (HNSCC) has been enhanced by the emergence of immunotherapy. A biological phenomenon unique to immunotherapy is pseudoprogression, an increase in tumor burden or the appearance of a new lesion subsequently followed by tumor regression. ⋯ These results provide confidence in the safety and efficacy of radical chemo-radio-immunotherapy for the treatment of recurrent, unresectable or metastatic HNSCC.

Uric acid (UA) and HDL-cholesterol (HDL-C) level are closely associated to the cardiovascular disease (CVD) morbidity. The UA/HDL-C ratio (UHR), a new parameter combination of serum UA and HDL-C, attracts attention for its association with metabolic and inflammatory conditions. There may exists the association between UHR and arterial stiffness. ⋯ This study revealed the nonlinear relationship between UHR and baPWV. A significant correlation between UHR and baPWV existed in females but not in males. Fatty liver status, BMI, and menopausal status may affect the above association.

Case Reports
ANCA-negative eosinophilic granulomatosis with polyangiitis complicated by peripheral nerve damage: A case report.
Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare autoimmune disease that can affect multiple systems of the body and is characterized by asthma, blood and tissue eosinophilia, and small vascular inflammation. Eosinophilic tissue infiltration and extravascular granuloma formation can lead to any organ damage, but peripheral neuropathy is relatively rare. ⋯ EGPA is a rare disease that can affect multiple systems and has diverse clinical manifestations, with no specific manifestations in the early stage. Diagnosis is difficult, and there is a high misdiagnosis rate. The rate of ANCA positivity for this disease is not high, and clinicians should consider the possibility of ANCA-negative EGPA.

To study the anatomical orientation of the posterior group of calyces based on reconstructed images of computerized tomography urography (CTU) and provide a novel classification with its clinical significance. Clinical data of a total of 1321 patients, who underwent CTU examination in our hospital were retrospectively analyzed. Among these, a total of 2642 3-dimensional reconstructed images of CTU scans were considered in this study. ⋯ In this study, the posterior group calyces were found to be present across all patients. The posterior group calyces were highest in the classical branching type, of which anatomical typing was highest in type b. The typing of the posterior group of calyces could provide an anatomical basis for percutaneous nephrolithotomy (PCNL) puncture from the posterior group.
