The prevalence of chronic obstructive pulmonary disease in hospitalized tobacco smokers with peripheral artery disease.

Peripheral artery disease (PAD) and chronic obstructive pulmonary disease (COPD) are inflammatory diseases. These two entities often co-exist, but little is known about the prevalence of this phenomenon in patients with PAD. The objectives of this prospective cross-sectional study were to determine the prevalence of COPD in patients with PAD and to assess the frequency of COPD underdiagnosis in this group of patients.

Bariatric Surgery and Metabolic Status.

: Obesity is associated with numerous co-morbidities, including dyslipidemia, insulin resistance and diabetes mellitus. Bariatric surgery is the mainstay of treatment for obesity as the only method with confirmed long-term effects in weight reduction and the remission of comorbidities. Postoperative recommendations leading to changes in dietary habits and changes in digestion and absorption in the gastrointestinal tract after bariatric surgery may additionally influence the levels of laboratory parameters that reflect the metabolic and nutritional status.

During EIRR, various proteins are released into gingival sulcus fluid (GCF). The aim of the study was to monitor the levels of selected proteins in GCF in children (8-16 years of age) in order to assess their utility in the early diagnosis of EIRR.

Synchronous Development of Multicentric Malignant Peripheral Nerve Sheath Tumors: Institutional Review.

Background: Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue sarcomas, with approximately 50% occurring in patients diagnosed with neurofibromatosis type 1 (NF-1). NF-1 occurs in approximately 1/3000 individuals, and given that the lifetime prevalence of MPNST is estimated at 8%-13%, synchronous development of separate MPNSTs is plausible. We sought to report the incidence of synchronous MPNST in a cohort of pathology-proven cases since 1994.

Nontraumatic Subdural Hematoma and Intracystic Hemorrhage Associated with a Middle Fossa Arachnoid Cyst.

Intracranial arachnoid cysts (ACs) are relatively common findings that can be seen in up to 2% of patients. They are generally found incidentally with a benign clinical course and can be usually managed by observation. We report an unusual case of a middle fossa AC presenting with spontaneous intracystic hemorrhage along with subdural hematoma (SDH) causing significant mass effect and midline shift requiring surgical treatment.
