Sphenoidal sinus carcinoma is a rare cause of hypercalcemia of malignancy. We report on a 37-year-old male with sphenoidal sinus carcinoma with intracranial extension who developed hypercalcemia of malignancy with progressing disease and demonstrated diffuse metastatic visceral calcifications of lungs, myocardium, stomach, kidneys and thyroid on follow-up 99mTc-methylene diphosphonate bone scan. In the absence of extensive skeletal metastases, bone scan help confirm humoral nature of hypercalcaeimia.

Unlabelled: In very preterm-born infants, nutritional intake is important to reduce the risk of severe metabolic bone disease including the risk of a lower bone mineral density (BMD). The aim of this study was to evaluate bone mineral content (BMC) and BMD (measured as BMC per bone area (BA)) at six years of age in very preterm-born infants fed different diets post-discharge. Data on this topic so far is insufficient, and with this study we aim to supply more useful data.

Background: To compare the effect of minimally invasive and open transforaminal lumbar interbody fusion (TLIF) approaches in fusing the L4-L5 segment and predicting the potential risk of adjacent segment degeneration (ASD).

Methods: A computed tomography scan image was processed and the three-dimensional model of the L1-L5 spine was reconstructed. The minimally invasive and Open TLIF finite element models were constructed.

Objective: This study aimed to evaluate the efficacy and safety of bisphenol A-glycidyl methacrylate (bis-GMA) without UV light polymerization for the repair of refractory iatrogenic cerebrospinal fluid (CSF) leaks with large skull base defects.

Background: CSF leakage remains a common complication after neurosurgical interventions with a substantial resultant impact on morbidity and increased healthcare costs. The management of refractory CSF leaks with large skull base defects remains challenging.

A CT Radiologic Assessment of the Incidence of Cochlear-Facial Dehiscence and the Thickness of Bone between the Cochlea and Facial Nerve among Normal Temporal Bones.

J Neurol Surg B Skull Base

Department of Head and Neck Surgery, David Geffen School of Medicine, University of California, Los Angeles, California, CA 90095, United States.

Cochlear-facial dehiscence (CFD) is a relatively new diagnosis which occurs when the bony partition between the labyrinthine segment of the facial nerve and the cochlea is dehiscent. This is considered one of several third window lesions which produce varying degrees of auditory and vestibular symptoms. Imaging studies have identified a consistently higher incidence of CFD when compared with the only histopathologic study present in the literature.

Background: To analyze the effects of the positioning of a bolt in the femoral neck system (FNS) on the short-term outcomes of middle-aged and young adults with displaced femoral neck fractures (FNFs).

Methods: This was a retrospective study involving 114 middle-aged and young adults with displaced FNFs who were surgically treated with internal fixation via the FNS in the Department of Orthopedics, Suzhou Municipal Hospital, from December 2019 to January 2023. The degree of deviation of the central axis of the femoral head and neck from the tip of the bolt (W), the tip‒apex distance (TAD) and the length of femoral neck shortening (LFNS) were measured on postoperative X-ray and computed tomography (CT) scan images.
