ABSTRACT

Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis (WG), is a multisystem autoimmune disease of unknown etiology often misdiagnosed as pneumonia. The hallmark features include necrotizing granulomatous inflammation and pauci-immune vasculitis in small and medium-sized blood vessels. We described a 15-year-old female with a history of six months of acne-like facial and peri-auricular lesions. She had received conventional treatment for acne (antibiotics + topical corticosteroid) with no response. She also had a history of chronic coughs, which always diagnosed and treated as sinusitis. In addition, she had a history of frequent dysuria, which always diagnosed and treated as a urinary tract infection. Given the history, with suspicion of a multi-systemic disease such as vasculitis; we performed some diagnostic laboratory and radiologic tests in order to rule out the possible etiologies. The results were positive for cytoplasmic anti-neutrophil cytoplasmic antibody (C-ANCA). The urine analysis suggested the involvement of kidney micro-vasculature. In addition, two nodular lesions with the cystic pattern were observed in the CT scan of the lungs. However, the skin and nasal biopsies revealed no evidence of chronic necrotizing vasculitis or granulomatous lesion. Nonetheless, treatment was initiated with a strong suspicion of GPA. Following the treatment, the patient's symptoms completely disappeared, and the diagnosis of GPA was confirmed.

ABSTRACT

The purpose of this research was the fabrication, statistical optimization, and in vitro characterization of insulin-loaded poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) nanoparticles (INS-PHBV-NPs). Nanopar-ticles were successfully developed by double emulsification solvent evaporation method. The NPs were characterized for particle size, entrapment efficiency (EE%), and polydispersity index (PDI). The NPs also were characterized by scanning electron microscopy (SEM), Fourier transformed infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and circular dichroism (CD). The optimum conditions were found to be 1.6% polyvinyl alcohol (PVA), 0.9% of PHBV, and 15 mg/ml of insulin with the aid of the Box-Behnken experimental design results. The optimized NPs showed spherical shape with particle size of 250.21 ± 11.37 nm, PDI of 0.12 ± 0.01, and with EE% of 90.12 ± 2.10%. In vitro drug release pattern followed Korsmeyer-Peppas model and exhibited an initial burst release of 19% with extended drug release of 63.2% from optimized NPs within 27 d. In conclusion, these results suggest that INS-PHBV-NPs could be a promising candidate for designing an injectable sustained release formulation for insulin.

ABSTRACT

BACKGROUND AND PURPOSE: Malnutrition is a common problem in patients who are hospitalized in surgical and medical wards. Surgical patients, geriatric populations and individuals with severe illness are more vulnerable to malnutrition during their hospitalization course.The purpose of this study was evaluation of parenteral nutrition services in a referral teaching hospital, Tehran, Iran. METHOD: Medical records of 72 patients who received parenteral nutrition during one year period in different surgical and medical wards of Imam Khomeini hospital were reviewed retrospectively by clinical pharmacists. Criteria for initiation of parenteral nutrition, selection of appropriate formulation and monitoring parameters were assessed based on the American Society of Parenteral and Enteral Nutrition recommendations. RESULTS: Based on the patients' anthropometric parameters and serum albumin levels, 4.2%, 75% and 20.8% of the patients were well-nourished, moderately malnourished and severely malnourished respectively at the hospital admission and before nutritional support. Adequate calorie, protein, carbohydrate and lipid supports were achieved in 21.1%, 32.4%, 23.7% and 10.5% of the patients respectively. About 91% of the patients experienced at least one complication of the nutritional support. CONCLUSION: In this evaluation, several errors in assessment, establishing goals, and monitoring of parenteral nutrition regimens have been detected. Approximately all of the patients did not receive to the trace elements supports goals.
