Surgery passes through a continuous evolution, thanks to the introduction of new technologies and techniques. Tissue-sparing
surgery is a concept introduced in the last years to address prosthetic surgery to a more conservative fashion. We discuss
the TSS decalogue with a critical eye, pointing out how traditional surgery is evolving in accordance with TSS statements.

Stimulation of tear secretion by topical agents that increase cyclic nucleotide levels 总被引:1,自引:0,他引:1
J P Gilbard S R Rossi K G Heyda D A Dartt 《Investigative ophthalmology & visual science》1990,31(7):1381-1388
The authors examined the effect of topical application of agents known to increase cyclic nucleotide levels on tear secretion by accessory lacrimal gland tissue in their rabbit model for keratoconjunctivitis sicca (KCS). Tear secretion was studied by changes in tear film osmolarity and tear volume caused by application of the agents relative to application of isotonic buffer solution alone. A decrease in tear film osmolarity or increase in tear volume was interpreted as an increase in tear secretion. Irritative stimulation was distinguished from pharmacologic stimulation by the prior use of topical proparacaine. The following agents significantly decreased tear film osmolarity and increased tear volume: vasoactive intestinal peptide (2 X 10(-8) to 2 X 10(-6) M); three pro-opiomelanocortin fragments alpha-, beta-, and gamma-melanocyte stimulating hormone at 10(-4), 10(-3), and 10(-3) M, respectively; the permeable cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) analogs 8-Br cAMP (0.3-3.0 X 10(-3) M) and 8-Br cGMP (1.0-10.0 X 10(-3) M); and the cyclic nucleotide phosphodiesterase inhibitor 1-isobutyl-3-methyl xanthine (0.3-3.0 X 10(-3) M). Forskolin (2 X 10(-4) M), which activates the catalytic subunits of adenyl cyclase, increased tear volume significantly. Secretin, adrenocorticotropic hormone, and pilocarpine were ineffective. The authors conclude that agents that increase either cAMP or cGMP levels pharmacologically stimulated tear secretion when applied topically to rabbit eyes with surgically induced KCS. 相似文献

The concentration of brain type creatine kinase (CK-BB) was measured in blood from the internal jugular vein in 32 children (less than 1 year old) with congenital heart disease. In transposition of the great arteries the CK-BB levels were significantly higher than in children without cyanosis (10.1 +/- 4.1 vs. 3.0 +/- 0.5 ng/ml). A negative correlation was found for CK-BB concentration and arterial oxygen saturation (r = -0.41, p less than 0.02 for all children and r = -0.62, p less than 0.05 for those with tetralogy of Fallot). It is suggested that the increased CK-BB levels in the blood of cyanotic children reflect chronic cerebral hypoxia, which may explain other reports of reduced psycho-intellectual function in patients with cyanotic heart disease. 相似文献

Palliation of cardiac malformations associated with right isomerism (asplenia syndrome) in infancy 总被引:1,自引:0,他引:1
R Di Donato D di Carlo C Squitieri E Rossi A Ammirati B Marino C Marcelletti 《The Annals of thoracic surgery》1987,44(1):35-39
Right isomerism is characterized by the combination of an obstructed pulmonary outflow tract and a total anomalous pulmonary venous connection (TAPVC), which is obstructed in nearly half of the patients. Fourteen patients less than 2 years of age with right isomerism have been seen in our unit. Thirteen of them underwent palliation consisting of a systemic-pulmonary shunt (10 patients) or a combination of shunt and TAPVC repair (3). There were 7 hospital deaths (54%). The presence of obstructed pulmonary venous drainage was the major risk factor in the surgical treatment of these complex cardiac anomalies (p less than .02). Guidelines for the palliative management of right isomerism are suggested. 相似文献

Abstract
Surgical management of trapeziometacarpal joint osteoarthritis (OA) is still controversial. The aim of this study was to evaluate
and compare results of trapeziometacarpal arthrodesis and of tendon interposition arthroplasty. One hundred twenty-six patients
suffering from trapeziometacarpal OA underwent surgery between 1996 and 2001. Of these patients, 62 (78 thumbs) treated with
joint arthrodesis and 33 (41 thumbs) treated with tendon interposition arthroplasty with abductor pollicis longus (APL) have
been evaluated at follow-up and therefore entered this study. Mean age was 53 years, while the mean follow-up was 36 months.
Overall results were satisfactory in 84 patients with good pain improvement. Patients treated with arthrodesis showed better
functional ability in bi-digital pinch and grip strength. First finger opposition motion, however, was better conserved in
patients treated with interposition arthroplasty. Fusions had an 11.5% complication rate (9 thumbs) with nonunions, whereas
14.8% (6 thumbs) of patients treated with interposition arthroplasty developed 1 first metacarpal base collapse, resulting
in 1 first ray length reduction. Despite complications, however, patients did not report unsatisfactory results and generally
experienced marked pain reduction. This study shows that arthrodesis can be considered the treatment of choice in patients
suffering from trapeziometacarpal OA at Eaton stage III or less, whatever the age and when a good pinch strength is needed. 相似文献

Objects Genetic syndromes associated with ependymoma are uncommon, with the exception of NF2. We describe two cases of ependymoma
presenting with Klinefelter’s Syndrome (KS) as co-morbid condition.
Materials and methods The first patient was diagnosed for KS during pregnancy; he also presented a thyroid agenesis and a deficit of methyltetrahydrofolate
reductase (MTHFR); at 30 months of age he was operated on for a grade II ependymoma of IV ventricle; after a multiple-stage
surgery, he underwent oral chemotherapy and stereotactic radiotherapy, but after 15 months he presented a local recurrence
and died. The second patient was diagnosed for KS at the age of 16 months; at 10 years of age, due to back pain, he underwent
an MRI, which showed a cauda equine tumor. He underwent surgery and radiotherapy. Histology was of mixopapillary ependymoma.
Conclusion In a review of literature, various neoplasms have been described in association with KS. To our knowledge, these are the first
two cases reported of ependymoma associated to KS. A retrospective study of 44 monoinstitutional ependymoma cases demonstrated
association with genetic syndromes in 22%. 相似文献
