ObjectiveThis study aimed to evaluate the possible effects of surgical procedures on mortality and to identify the possible risk factors for mortality in the management of geriatric hip fractures.MethodsA total of 191 patients (105 women and 86 men; mean age 82.26±9.681 [60–108] years) with AO/OTA 31A2.2 intertrochanteric fractures and treated with sliding hip screw, proximal femoral nail, or hemiarthroplasty were included in this retrospective cohort study. The treatment type was decided by the responsible surgeon according to the patients’ pre-injury activity level, bone quality, and features of the fracture. Age, sex, type of fracture, type of surgery performed, American society of anesthesiology (ASA) grade, type of anesthesia, time to surgery, type of physical therapy, length of hospital stay, and number of comorbidities were documented. We evaluated the 30-day and 1-year mortality of patients treated with sliding hip screw (SHS), proximal femoral nail antirotation (PFN-A), or hemiarthroplasty and identified the possible risk factors for mortality.ResultsA total of 49 patients underwent SHS, 58 underwent PFN-A, and 84 underwent hemiarthroplasty. Of these, 2 patients with SHS, 2 with PFN-A, and 11 with hemiarthroplasty died within 30 days after surgery, whereas 7 patients with SHS, 15 with PFN-A, and 23 with hemiarthroplasty died 1 year after surgery. The 30-day and 1-year overall mortality rates were 7.9% and 23.6%, respectively. Both the 30-day and 1-year mortality risks were higher in patients undergoing hemiarthroplasty than in patients undergoing SHS (p=0.068 versus 0.058). The 30-day mortality was higher in patients receiving general anesthesia than in those receiving combined spinal and epidural anesthesia (p=0.009). The 1-year mortality risk was higher in patients with ASA grade 4 than in those with grade 1 and 2 (p=0.045). Advanced age (p=0.022) and male sex (p=0.007) were also found to be the risk factors for 1-year mortality.ConclusionWe demonstrated that higher ASA grade, male sex, general anesthesia, and hemiarthroplasty procedures are associated with higher mortality rates in elderly patients with hip fractures. Thus, we highly recommend orthopedic surgeons to consider all these factors in the management of intertrochanteric hip fractures in the geriatric population.Level of EvidenceLevel IV, Prognostic Study 相似文献
This study aims to synthesize and characterize an economical and ecological adsorbent with high adsorption capacity. For this purpose, the peanut shells (Pistacia vera L.) were modified chemically. After the synthesis of activated carbon (AC), the optimum conditions for enrichment steps were performed using parameters: pH and contact time for uranium in the model solutions. The measurements were carried out by inductively coupled plasma-mass spectrometry (ICP-MS). From the shapes of the BET isotherms, the AC obtained exhibits type I. The study indicated that the surface area and total pore volume of the AC were found to be 679.9 m2 g−1 and 0.31 cc g−1, respectively. The adsorption capacity was found to be 260 mg g−1. The optimum pH was found to be 6.0 for enrichment using the AC obtained by sulfuric acid as a chemical-modifier. The optimized method was applied to enrichment of U at ppb levels in the model solutions.

Since the 1970s, resistance to antimicrobial agents has become an escalating problem. In the last 25 years, treatment of infections caused by Gram-positive bacteria has been more problematical than ever, with infections being caused by multidrug-resistant organisms, particularly methicillin-resistant staphylococci, penicillin- and erythromycin-resistant pneumococci, and vancomycin-resistant enterococci. There is a continuing effort in the pharmaceutical industry to develop new antimicrobial agents for the treatment of resistant infections. Linezolid, quinupristin-dalfopristin, daptomycin, tigecyline, new glycopeptides and ceftobiprole are the main agents recently introduced or under clinical development. This review summarises their major properties, the results of recent studies with these agents, and future treatment possibilities. 相似文献
Medpor implants were placed on the periosteum of the mandible in infant rabbits to study their effects on growth. Three months later radiological and histopathological studies were performed in situ and after removal of the mandible. The authors demonstrate that implants did not affect normal development of the mandible; however, there was a decrease in bone thickness and a mononuclear cell reaction was caused where the implant came in contact with the bone. 相似文献
Objectives: To investigate the correlation of nuclear p53 accumulation with disease outcome in a cohort of patients with transitional cell carcinoma of the bladder.
Methods: A total of 90 patients (11 female, 79 male) with transitional cell carcinoma of the bladder were included in this study. Tumour samples from the primary tumour were analysed by immunohistochemistry for nuclear accumulation of p53 protein. Outcome of each patient was recorded and investigated for a possible relation with p53 status.
Results: Nuclear p53 deposition was determined in 22 specimens. The nuclear p53 deposition was seen in less than 20% of the nuclei examined in 13 and more than 20% in 9 cases. No stromal staining was observed. Nuclear p53 deposition was present in 15.2% (7/46) of grade 2 tumours, and 34% (15/44) of grade 3 tumours (p=0.037). Stage distribution revealed 15.5% (5/33) positivity in stage pTa, 25.8% (8/31) in pT1 and 34% (9/26) in stage pT2–3 tumours. Tumours with p53 nuclear accumulation had a higher rate of recurrence and progression and shorter survival.
Conclusion: Results of the current study indicate p53 as an important factor in determination of biological behaviour of bladder cancer. 相似文献
From November 3, 1975 to November 3, 1990, 874 kidney transplants were performed at our centers. Of these, 675 (77.2%) were from living donors and 199 (22.8%) were from cadaver donors. Five hundred eighty (66.4%) of the living donors were first degree related while 99 (11.3%) were unrelated or second degree related donors, 29 of which were spouses. All donor recipient pairs were ABO-compatible, with the exception of one pair. Donor recipient relations were wife to husband in 25 cases and husband to wife in 4 cases. All were first grafts and started functioning during surgery. In this series, the follow-up for the recipients was 4 to 64 months (mean 33.5 ± 4.5 months). One-year patient survival and graft survival rates were 92.4% and 81.9%, respectively. Two-year patient survival and graft survival rates were 92.4% and 78.2%, respectively. The single ABO-incompatible case is also doing well, 21 months postoperatively. This study demonstrates that the interspouse kidney transplantation may be used when cadaver organ shortage is a problem. While providing the couple with a better quality of life, interspouse kidney transplantation also enables the couple to share the joy of giving and receiving the gift of life from one another.
Resumen En nuestro centro se efectuaron 874 trasplantes renales entre noviembre 3 de 1975 y noviembre 3 de 1990; 675 (77.2%) fueron de donantes vivos y 199 (22.8%) de donantes cadavéricos; 580 (66.4%) de los donantes vivos fueron familiares de primer grado y 99 (11.3%) fueron donantes no relacionados familiarmente o familiares de segundo grado, de los cuales 29 eran cónyuges. Todas las parejas donante-recipiente exhibieron compatibilidad ABO, con excepción de una. La relación donante-recipiente fue esposa a esposo en 25 casos y esposo a esposa en 4 casos. Todos los injertos eran de primera vez y todos comenzaron a funcionar en la mesa de cirugía. El seguimiento osciló entre 4 y 64 meses (33.5 ± 4.5). Las tasas de sobrevida a un año del paciente y del injerto fueron 92.4% y 81.9% respectivamente; las tasas a dos años fueron 92.4% y 78.2% respectivamente. El único caso ABO no compatible también se encuentra bien, a 21 meses en la actualidad. El presente estudio demuestra que el trasplante renal entre esposos puede ser utilizado cuando haya escases de órganos cadavéricos. Al tiempo que permite una mejor calidad de vida, el procedimiento da a la pareja la oportunidad de gozar el hecho de otorgar y de recibir el regalo de la vida entre uno y otro.
Résumé Nous avons effectué 874 transplantations rénales dans nos centres de transplantation entre le 3 Nov, 1975 et le 3 Nov, 1990. Parmi celles-ci, 675 (77.2%) provenaient de donneurs vivants et 199 (22.8%) des reins provenaient de cadavres. Cinq cent quatre vingt des donneurs vivants (66.4%) étaient parents au premier degré alors que 99 (11.3%) étaient parents au 2è degré ou n'étaient pas parents, parmi lesquels 29 étaient des époux. Tous les couples donneur/receveur, sauf un, étaient compatibles dans le système ABO. Le couple donneur/receveur était femme à mari dans 25 cas et mari à femme dans quatre. Il s'agissait dans tous les cas d'une première greffe et qui a commencé à bien fonctionner sur la table d'opération. Dans cette série, le suivi des receveurs allait de 4 à 64 (33.5 ± 4.5) mois. Les taux de survie des malades et des greffes à un an étaient respectivement de 92.4% et 81.9%. Les taux de survie des malades et des greffes à deux ans étaient respectivement de 92.4% et 78.2%. Le seul cas avec incompatabilité ABO va très bien avec un recul de 21 mois. Cette étude montre que la transplantation entre époux est une solution valable en cas de manque de reins. En plus d'améliorer la qualité de survie du receveur et par là même du couple, cette variété de transplantation donne également au couple la possibilité d'avoir la joie de donner et de recevoir un cadeau de vie de leur époux.
The aim of the present study was to examine subpreputial bacteriology and to compare it with the urine cultures of healthy
male children. Seventy-two male children were divided into two groups as A and B according to age. In both groups preputial
sac and urine cultures were taken simultaneously. Gram (+) enteric cocci were the most common isolated pathogens from the
preputial sac in group B. Enterobacter, E. coli and staphylococci species were isolated from the urine cultures of three patients in group B. We could not find any difference
between the preputial sac swabs of group A and B patients, but the isolation rate of urine cultures of group A patients was
significantly higher than group B (p < 0.05). The findings of the present study support a potential role of the prepuce acting as a reservoir of faecal bacteria
in the pathogenesis of UTI in male infants, especially in the first year of life. Improved penile hygiene after the first
year of life does not alter the subpreputial bacteriology, but significantly decreases the contamination of urine.
