Introduction
The anatomic abnormalities in developmental dysplasia of hip (DDH) often make total hip replacement (THR) inevitable at a younger age. However, there is no universal gold standard technique of THR for high dislocated dysplastic hips.Materials and methods
Here we present the outcomes of midterm follow-up after THR in patients diagnosed with DDH Crowe type III and IV hospitalized in a tertiary center in Iran for whom placement of a cup in true acetabulum and selective transverse subtrochanteric osteotomy was performed. Pre- and postoperative Harris Hip Score, leg length discrepancy and postoperative complications were evaluated.Results
A total of 48 patients with DDH Crowe type III and IV (uni- or bilateral which made 52 hips) were studied. Mean age of patients was 41 years with minimum follow-up ranging from 12 months to 3 years. Mean Harris Hip Score significantly improved from 41.70 preoperatively to 88.1 at last follow-up postoperatively. Leg length discrepancy of less than 2 cm was observed which was well tolerated using shoe lifts. Regarding postoperative complications, two patients had transient peroneal nerve palsy in early postoperative period which recovered within 2 months. No other major complication was encountered.Conclusion
THR in patients with DDH (Crowe III and IV) with a cup positioned in true acetabulum and transverse subtrochanteric osteotomy is a safe successful procedure.252.
It is shown that phosphodiesterase type 5 (PDE5) inhibitors such as sildenafil can modulate pulmonary arterial hypertension
(PAH) via increasing the level of guanosine-3,5-cyclic monophosphate (cGMP) and decreases pulmonary artery pressure (PAP).
In this study we determined the effectiveness of sildenafil and compared its efficacy with inhaled nasal oxygen (O2) during cardiac catheterization in patients with congenital heart diseases (CHD) and PAH, as a test of feasibility for surgical
repair of the patients. We studied 15 patients, 9 male and 6 female, with a mean age of 8.3 years. Hemodynamic measurements
were made at baseline, after O2 administration for 20 min (5 L/min by mask), and then 45 min after administration of a single dose of sildenafil (0.5 mg/kg
orally or via nasogastric tube). Mean PAP at baseline was 72.2 ± 12.54 mm Hg and was reduced by sildenafil to 52.5 ± 9.6 and
by O2 to 61.3 ± 10.39. Both sildenafil and O2 decreased PAP effectively (p = 0.08 and p = 0.04, respectively). Pulmonary vascular resistance (PVR) was calculated for 12 patients, with a baseline level of 9.08 ± 1.09 mm
Hg · L−1 · min, which was significantly decreased by O2, to 3.74 ± 0.43, and by sildenafil, to 5.93 ± 0.75 (p = 0.005 and p = 0.05, respectively). Sildenafil, as a single oral dose, can effectively reduce PAP and PVR. This novel PDE5 inhibitor can
be used for assessment of feasibility of operation for patients with CHD and PAH when inhaled NO is not available. 相似文献

Immune responses are the main causes of immune system-related diseases such as hypersensitivities and autoimmunity. It has also been established that cytokines play key roles in the regulation of immune responses which have been shown to be important in the pathogenesis of the diseases. IL-10, the main anti-inflammatory cytokine, is produced by several immune cells such as T regulatory and Th2 lymphocytes, activated macrophages, B regulatory lymphocytes as well as other cell types. It plays a key role in the regulation of immune responses after microbe elimination (homeostasis) and against self-antigens to prevent hypersensitivity and autoimmune diseases, respectively. Studies showed that a single nucleotide polymorphism (SNP) at the -592 position of IL-10 is associated with its regulation of expression. This review addresses the recent information regarding the association of the polymorphism at position -592 of IL-10 with immune-related diseases including type 2 diabetes with and without nephropathy, multiple sclerosis, and asthma with an emphasize on Iranian patients. 相似文献
