RESUMEN
PURPOSE: The aim of the study was to investigate the association between serum 25-hydroxyvitamin D status within the last 6 months prior to COVID-19 infection and parameters of immune function and clinical outcomes. METHODS: Fifty-six patients, who were admitted to the emergency clinic and diagnosed with COVID-19 infection, were included in the study. Data on clinical characteristics, inflammatory parameters and vitamin D status were recorded for each patient. All the participants had data on 25-hydroxyvitamin D status within the last 6 months prior to COVID-19 infection. RESULTS: The patients were stratified as those with vitamin D status less than 20 ng/mL and higher than 20 ng/mL. A group with vitamin D status less than 20 ng/mL had lower lymphocyte counts and lower haemoglobin levels that was statistically significant (respectively; p = 0.021, p = 0.035). Higher C-reactive protein (CRP) levels were seen in the vitamin D-deficient group (p = 0.013). It was observed that vitamin D status of the patients who required oxygen therapy were lower than those who did not require oxygen therapy, not statistically significant (p = 0.05). Patients who did not use vitamin D supplementation within 6 months prior to COVID-19 infection had more likely to be diagnosed with pneumonia (p = 0.004). CONCLUSION: Cases with lower vitamin D status had increased inflammatory markers and worse clinical outcomes than patients with higher vitamin D status. This study suggests that vitamin D status can be used as a prognostic factor in COVID-19 patients, and vitamin D supplementation can be recommended to improve the clinical outcomes in COVID-19 infection.

We present a 65-year-old man who had a significant arteriovenous fistula between the right arteria profunda femoralis and vena profunda femoralis. He had evidence of chronic venous insufficiency and chronic leg ulcers on his right leg, and he had clinical findings of congestive heart failure. An arteriovenous fistula was responsible for all of clinical situation that had been caused by a shotgun wound 15 years ago. Using ultrasonography, after palpating a marked thrill and mass during physical examination, established the diagnosis of arteriovenous fistula. Angiography was performed both to delineate the suspected vascular anatomy and to show the coronary arteries. The patient was operated on and no complication was experienced during or after the procedure. Dramatic improvement was seen in the clinical picture just after surgery, and heart size markedly reduced both on chest X-ray and echocardiographic examination.

A 60-year-old man presented with a cholesterol crystal embolism that gave a rather confusing clinical picture. An immediate multidisciplinary approach established the diagnosis and the rapid, dramatic skin loss that exposed vital structures over his thigh and lower leg was reconstructed by an ipsilateral inferior pedicled rectus abdominis musculocutaneous flap with a lateral oblique cephalad fasciocutaneal component. The case, which a plastic surgeon would rarely encounter, is interesting because of the diagnostic approach and the management.

Five cases of upper extremity aneurysms are reported in 4 male and 1 female patients. Four were of traumatic and one of arteriosclerotic origin. Diagnosis and treatment are discussed.
