Prevalence and Associated Factors of Vitamin D Deficiency in High Altitude Region in Saudi Arabia: Three-Year Retrospective Study.

Background: Vitamin D has many functions in the human body, and its deficiency is associated with skeletal and non-skeletal diseases. Vitamin D deficiency (blood level of 25 (OH) vitamin D < 20 ng/mL) has been reported worldwide, including Kingdom of Saudi Arabia (KSA). Its prevalence and associated factors vary according to KSA region. Therefore, this study aimed to explore the prevalence and risk factors of vitamin D deficiency in the Taif region of KSA. Methods: This retrospective study included patients who attended outpatient clinics at the Alameen General Hospital from 2019 to 2021. Demographic, clinical, and laboratory data were collected using a hospital software system. Results: The study included 2153 patients and vitamin D deficiency was diagnosed in 900 (41.8%) of whom were diagnosed with vitamin D deficiency. It was more common in males (P=0.021), younger age (<0.001), and in patients without comorbidities. There was a positive correlation between 25 (OH) vitamin D levels and blood cholesterol, high-density lipoprotein, calcium, and vitamin B12 levels. In the binary logistic regression analysis, age was the most significant predictor (P<0.001), followed by the absence of thyroid disease (P=0.012) and asthma (P=0.030). Conclusion: Vitamin D deficiency is common in the Saudi population despite sunny weather in KSA. It is more prevalent among males, younger individuals, and those without comorbidities such as thyroid diseases and asthma.

Clinical Outcomes of Long Head Biceps Tendinitis Treatment by a Semitenodesis Technique.

Introduction Long head biceps (LHB) tendon pathology results in anterior shoulder pain, affecting activities requiring overhead movement and forward flexion. Current surgical options for those in whom conservative management failed include tenotomy and tenodesis, and both have considerable success rates and various complications. Herein, we present a novel technique using tenotomy with autotenodesis of the LHB. Methods Patients with isolated LHB tendinopathy and for whom the six-month conservative treatment failed were included in our study. Our semitenodesis technique was performed from May 2015 to May 2021. All patients underwent postoperative rehabilitation and were followed in the clinic to document the visual analog scale (VAS) score, constant functional score, supination and flexion power, and postoperative satisfaction score. We used IBM SPSS Statistics for Windows version 20.0 (IBM Corp., Armonk, NY) to analyze our data. Results The study included 26 patients with a mean age of 50 ± 4.3 years and a male predominance. Following our technique, the postoperative VAS score improved significantly from 8.8 to 3 within three months and decreased to 0.4 during the final follow-up. The shoulder average constant score improved significantly from 45 ± 4 to 79 ± 5, in addition to a high postoperative mean satisfaction score. Only one patient had a Popeye sign deformity, making an incidence percentage of 3.8% with our technique. Conclusions We conducted this study to assess the outcomes of our novel technique using tenotomy with autotenodesis of the LHB compared to traditional techniques such as tenotomy and tenodesis. Our novel technique showed an improvement in pain score superior to patients who underwent tenodesis and tenotomy three months postoperatively. Furthermore, our technique yielded lower postoperative complications than traditional techniques. Our patients also scored a high mean of postoperative satisfaction. Therefore, our technique is a promising treatment option, proving its superiority over tenotomy and tenodesis in treating isolated LHB tendonitis.

Suprasellar pilocytic astrocytoma in an adult with hemorrhage and leptomeningeal dissemination: case report and review of literature.

Pilocytic astrocytoma (PA) is a low-grade tumor. It has an excellent prognosis after total resection. Leptomeningeal dissemination and hemorrhage are very rare to be associated with PA and lead to unfavorable prognosis. A 35-year-old man was diagnosed with a hemorrhagic suprasellar PA in 2006. Subsequent examination in 2007 revealed another large subdural hemorrhagic lesion in the sacral region, which proved to be PA by histopathologic assessment. Other leptomeningeal foci were discovered mainly at the craniocervical junction. The patient underwent subtotal resection and received chemotherapy with disease control for 7 years. Progression of the disseminated disease has recently occurred; however, the patient is still alive with stable disease after radiotherapy. The radiological features, management, and relevant literature are also presented. Our report heightens the awareness of PA in the adult population and the importance of close surveillance for the leptomeningeal spread, especially for sellar region tumors.
