We describe the results of an operative method applied in patients suffering from refractory ascites. Instead of the well-known shunt-implants we started to re-use Ruotte's method, which was published 100 years ago. According to our observations the anastomosis formed by the long saphenous vein and the peritoneal surface eliminates not only the known complications of the traditional shunt-operations but also provides an effective early and a late ascites inflow. The flow of the ascites was convincingly proven by regularly performed colour Doppler UH tests. This old/new method is applicable in patients with therapy-resistant ascites to eliminate the traditional shunt-models. 相似文献
More than thousand plastic operations were performed in our departments with ROMICRO-set during the last ten years. First we applied it for reconstructive and aesthetic augmentation of the breast. Thereafter, we developed new technique for gynecomastia and reconstruction of diastasis of the m. rectus abdominis sheath. According to our experience, the ROMICRO-set is a useful tool in plastic surgery. The ROMICRO-set can be used through a small incision to achieve three dimensional views with excellent exposure and lighting. 相似文献
STUDY OBJECTIVES: To investigate whether nitric oxide (NO) metabolites would be reduced in children affected by primary ciliary dyskinesia (PCD). DESIGN: Single-center observational study. PATIENTS: Fifteen children with PCD (seven boys; mean [+/- SEM] age, 10.3 +/- 0.7 years; mean FEV(1), 73 +/- 2.1% predicted) were recruited along with 14 healthy age-matched subjects (seven boys; mean age, 11.5 +/- 0.4 years; mean FEV(1), 103 +/- 5% predicted). INTERVENTIONS: We assessed the levels of nitrite (NO(2)(-)), NO(2)(-)/NO(3)(-) (NO(2)(-)/NO(3)(-)), and S-nitrosothiol in exhaled breath condensate, exhaled NO, and nasal NO from children with PCD compared to those in healthy children. MEASUREMENTS AND RESULTS: The mean exhaled and nasal NO levels were markedly decreased in children with PCD compared to those without PCD (3.2 +/- 0.2 vs 8.5 +/- 0.9 parts per billion [ppb], respectively [p < 0.0001]; 59.6 +/- 12.2 vs 505.5 +/- 66.8 ppb, respectively [p < 0.001]). Despite the lower levels of exhaled NO in children with PCD, no differences were found in the mean levels of NO(2)(-) (2.9 +/- 0.4 vs 3.5 +/- 0.3 microM, respectively), NO(2)(-)/NO(3)(-) (35.2 +/- 5.0 vs 34.3 +/- 4.5 microM, respectively), or S-nitrosothiol (1.0 +/- 0.2 vs 0.6 +/- 0.1 microM, respectively) between children with PCD and healthy subjects. CONCLUSION: These findings suggest that NO synthase activity may not be decreased as much as might be expected on the basis of low exhaled and nasal NO levels. 相似文献
m-Chlorophenylpiperazine (m-CPP), a potent 5-HT receptor agonist, is known to induce self-grooming in rats and exacerbate symptoms in patients with obsessive-compulsive disorder (OCD). To characterise the possible role, 5-HT(2B) and 5-HT(2C) receptors play in m-CPP-induced self-grooming, subtype-selective receptor antagonists were used. m-CPP significantly increased the amount of self-grooming in male Sprague-Dawley rats. This effect followed a bell-shaped dose-response curve with a peak at 0.6 mg/kg, i.p. Pretreatment with SB-242084, a subtype-selective 5-HT(2C) receptor antagonist (0.1-0.5 mg/kg, i.p.), reversed m-CPP-induced self-grooming. In contrast, pretreatment with the subtype-selective 5-HT(2B) receptor antagonist SB-215505 (1 mg/kg, i.p) did not block the effect of m-CPP. Two days after depletion of brain 5-HT by p-chlorophenylalanine (p-CPA, 2 x 50, 2 x 100 mg/kg, i.p.) m-CPP-induced responses were significantly enhanced compared to controls. Our studies provide evidence that direct activation of 5-HT(2C) receptors mediate m-CPP-induced self-grooming and the depletion of brain 5-HT sensitizes these receptors. 相似文献
Inherited antithrombin (AT) deficiency is a rare autosomal dominant disorder, caused by mutations in the AT gene (SERPINC1). Considering that the genotype phenotype relationship in AT deficiency patients remains unclear, especially in pediatric patients, the aim of our study was to evaluate genotype phenotype correlation in a Serbian pediatric population. A retrospective cohort study included 19 children younger than 18 years, from 15 Serbian families, with newly diagnosed AT deficiency. In 21% of the recruited families, mutations affecting exon 4, 5, and 6 of the SERPINC1 gene that causes type I AT deficiency were detected. In the remaining families, the mutation in exon 2 causing type II HBS (AT Budapest 3) was found. Thrombosis events were observed in 1 (33%) of those with type I, 11 (85%) of those with AT Budapest 3 in the homozygous respectively, and 1(33%) in the heterozygous form. Recurrent thrombosis was observed only in AT Budapest 3 in the homozygous form, in 27% during initial treatment of the first thrombotic event. Abdominal venous thrombosis and arterial ischemic stroke, observed in almost half of the children from the group with AT Budapest 3 in the homozygous form, were unprovoked in all cases.
Conclusion: Type II HBS (AT Budapest 3) in the homozygous form is a strong risk factor for arterial and venous thrombosis in pediatric patients.
What is Known:
• Inherited AT deficiency is a rare autosomal dominant disorder, caused by mutations in the SERPINC1gene.
• The genotype phenotype correlation in AT deficiency patients remains unclear, especially in pediatric patients.
What is New:
• The genetic results for our paediatric population predominantly showed the presence of a single specific mutation in exon 2, that causes type II HBS deficiency (AT Budapest 3).
• In this group thrombosis mostly occurred as unprovoked, in almost half of them as abdominal thrombosis or stroke with high incidence of recurrent thrombosis, in 27% during initial treatment.
Syndecan 4 (SDC4), a heparan sulfate proteoglycan, and neuropilin 1 (NRP1), a transmembrane receptor, are both involved in normal wound healing, but little is known about their possible role in venous leg ulcer pathogenesis. We aimed to investigate whether there are any expression abnormalities and/or gene polymorphisms of SDC4 and NRP1 associated with venous leg ulcer. SDC4 showed significantly lower mRNA and protein expression in the uninvolved dermis of venous leg ulcer patients ( n =15) compared with controls ( n =15; p =0.0136), while NRP1 showed no expression abnormalities. None of the examined SDC4 and NRP1 polymorphisms showed a difference in their allelic distribution between leg ulcer patients ( n =92) and controls ( n =92). We hypothesize that SDC4 may play an essential role not only in the inflammation and tissue formation phases of normal wound healing, but its expression abnormalities observed in the uninvolved dermis of venous leg ulcer patients may contribute to venous leg ulcer development. 相似文献
Solid papillary carcinoma (SPC) is a rare neoplasm of the breast showing a distinct morphology, neuroendocrine differentiation and should be divided into invasive and in situ subtype according to the current 2012 WHO classification of breast tumors. Here, we describe a case of a pure SPC, invasive‐type, in a 31‐years old female with an associated mammary Paget's disease (MPD) of the nipple showing a rare, CK7‐negative immune phenotype, which has not been reported so far. This unusual differential diagnosis should be added to the rare condition of CK7‐negative Paget's disease of the breast and complement a new feature to the characterization of SPC. 相似文献
