Benign extraskeletal chondromas are uncommon lesions with a predilection for the hands and the feet and can exhibit worrisome radiographic and histologic features mimicking chondrosarcomas. The authors present herein the case of a 74-year-old man with a painful mass at the dorsomedial aspect of the left foot. At 34 months after surgery the patient is disease-free with no evidence of recurrence. 相似文献

Biotechnology and tissue engineering have broad applications over several medical disciplines. The advances in the fields of biotechnology and tissue engineering offer new possibilities in the repair or regeneration of tissue lost to disease or injury. Consequently, a major portion of the research effort has focused on applications in orthopaedics with emphasis on the development of techniques for developing bone, articular cartilage, ligaments, tendons and nerve. Tissue engineering represents a multidisciplinary approach to solving some of the most demanding medical problems, particularly the creation of new tissues similar to those in the living organism. These new technical approaches include strategies in using new synthetic polymer formulations and various alternatives in tissue regeneration. This paper will examine the possible impact of biomolecular medicine in areas critical to the future of hand surgery, including tissue replacement, tissue regeneration, wound healing, and bone, tendon, cartilage, ligament and nerve repair. 相似文献

Formalin-fixed, paraffin-embedded samples of three normal minor salivary glands, 10 chronic submandibular sialadenitis, and three normal submandibular glands were studied immunohistochemically using the monoclonal antibody (Mab) B72.3 in order to have a better understanding of the distribution of tumor-associated glycoprotein (TAG-72). Diffuse expression of TAG-72 was observed in the mucous cells of normal minor salivary glands, and in the ducts with goblet cell metaplasia and/or hyperplasia of chronic submandibular sialadenitis (eight of 10). Focal expression of TAG-72 was seen in the acinar mucous cells of normal submandibular gland (three of three), and in the mucous cells of normal or atrophic acini of chronic submandibular sialadenitis (eight of 10). These results should be considered in the cytologic diagnosis of the mucoepidermoid carcinoma using the Mab B72.3 as a diagnostic aid, as well as in future studies for the radiation immunolocalization and immunotherapy of submandibular gland tumors. 相似文献

Seventy-one patients with thumb amputations, 45 complete and 26 incomplete nonviable, have been treated at the Microsurgical Unit of the Department of Orthopaedic Surgery at the University of Ioannina Medical School over the past 15 years. Of these thumb amputations, which included crush, avulsion, and guillotine injuries, three cases involved amputation of both thumbs. The three patients with complete bilateral thumb amputations are presented. Because of the importance of the thumb, microsurgical replantation efforts were made which proved successful for two of the patients. Replantation efforts in the third patient, who had severe crush injuries of both thumbs, were not successful. Bilateral thumb amputation is a serious and disabling injury. When replantation is attempted by a team of surgeons well trained in microsurgery, the final result can be impressive, with exceptionally good function of the replanted thumbs. © 1994 Wiley-Liss, Inc. 相似文献

In 34 of the 62 patients treated for complete multiple digital amputations, the severed part was not replanted in its anatomical position, but in the place of the most useful stump. This procedure is defined as transpositional digital microsurgery and refers to the transposition and replantation of any digit to another stump which plays a more significant role in the function of the hand. Twenty-eight patients had transposition of a digit, while six patients underwent thumb transposition. All except six of the transposed digits survived, while all of the thumbs survived the surgical procedure. The cosmetic appearance of the hand with a transposed digit or thumb was acceptable to the patients. Two-point discrimination was assessed to be 10–14 mm for the transposed digits, and the functional ability of the transplanted digit was comparable to digits which were replanted in their anatomical position. In conclusion, transpositional digital microsurgery remains a useful alternative for the treatment of multiple digit amputations, particularly in patients with severely damaged non-replantable amputated parts. © 1994 Wiley-Liss, Inc. 相似文献

Compensatory mechanisms in anterior cruciate ligament deficiency 总被引:1,自引:1,他引:0

The literature cites numerous studies involving the analysis of movement patterns in anterior cruciate ligament deficient (ACLD) patients. Although several in vivo biomechanical studies have shown that ACLD patients develop protective mechanisms against degenerative diseases, it seems that these adaptations fail to protect the knee from future pathology. Some authors state that ACLD patients adapt to the injury by avoiding quadriceps contraction during gait when the knee is near full extension. However, others have found increased hamstrings and decreased gastrocnemius activity, which normally contribute to the stability of the knee. It seems that further in vivo biomechanical investigation is required to understand the mechanisms of pathological knee joint motions and develop rehabilitation programs, which would delay the progress of developing long-term degenerative diseases. 相似文献

After the first successful replantation of a completely amputated extremity in a 12-year-old boy undertaken by Ronald Malt at the Massachusetts General Hospital in 1962 (Malt and McKhann, Journal of the American Medical Association, 189:716–722, 1964) numerous series of major limb replantations have been reported in adults. The reports of major limb replantation in children are relatively rare and are usually included in adult series. During the last 14 years, 18 children with major limb amputations were treated at the Microsurgical and Replantation Unit of the Department of Orthopaedic Surgery at the University of Ioannina Medical School. Of these, 13 were complete amputations (11 upper extremity and 2 lower extremity), while 5 were incomplete nonviable amputations (3 upper extremity and 2 lower extremity). The success rate following replantation of the complete amputations was 76.9%, while for the incomplete, nonviable amputations success was 80%. Preoperative evaluation, operative management, postoperative care, and the results of this difficult but rewarding procedure are analysed and discussed in this review. © 1994 Wiley-Liss, Inc. 相似文献

A retrospective analysis of five Sabin intertypic recombinant strains, isolated from human feacal specimens during the time
period 1978–1985 in Greece, was performed by RT-PCR, Restriction Fragment Length Polymorphism (R.F.L.P.) and sequencing. Of
the studied strains, three (EPA, EPB, EPC) were found to be bi-recombinant Sabin3/Sabin2/Sabin3 (S3/S2/S3), one strain was
characterized as a probable S3/S2- CAV18 or CAV21-S2/S1 multi-recombinant (EDP11) and one was identified as a tripartite one
S3/S2/S1 (EDP12). Samples EPA, EPB and EPC presented a common recombination junction in the 2C genomic region. Moreover, strains
EPA and EPB shared also the second recombination site in the 3D genomic region, whereas the second recombination of EPC was
also determined in 3D but in a different nucleotide position. Strains EDP11 and EDP12 presented both identical recombination
motifs and recombination sites. The first was detected in the 2C genomic region and the second in the 3D region. Strain EDP11
presented an interesting feature since a sequence of 120 nucleotides seems to have derived from a member of human enteroviruses
species C (CAV18 or CAV21). This finding is of great importance, considering that this strain (EDP11) was isolated from an
area and time period, where no Coxsackie A virus or poliovirus epidemics occurred. Our study underlines the role of specific
positions and motifs of the poliovirus genomic sequences involved in recombination events and prompts that Coxsackie A viruses
belonging to human enterovirus species C (genetically closely related to PV) are considered as the possible counterparts of
the recombination. 相似文献

Evaluation of molecular typing methods in characterizing a European collection of epidemic methicillin-resistant Staphylococcus aureus strains: the HARMONY collection 下载免费PDF全文

We analyzed a representative sample of methicillin-resistant Staphylococcus aureus (MRSA) from 11 European countries (referred to as the HARMONY collection) using three molecular typing methods used within the HARMONY group to examine their usefulness for large, multicenter MRSA surveillance networks that use these different laboratory methodologies. MRSA isolates were collected based on their prevalence in each center and their genetic diversity, assessed by pulsed-field gel electrophoresis (PFGE). PFGE groupings (≤3 bands difference between patterns) were compared to those made by sequencing of the variable repeats in the protein A gene spa and clonal designations based on multilocus sequence typing (MLST), combined with PCR analysis of the staphylococcal chromosome cassette containing the mec genes involved in methicillin resistance (SCCmec). A high level of discrimination was achieved using each of the three methodologies, with discriminatory indices between 89.5% and 91.9% with overlapping 95% confidence intervals. There was also a high level of concordance of groupings made using each method. MLST/SCCmec typing distinguished 10 groups containing at least two isolates, and these correspond to the majority of nosocomial MRSA clones described in the literature. PFGE and spa typing resolved 34 and 31 subtypes, respectively, within these 10 MRSA clones, with each subtype differing only slightly from the most common pattern using each method. The HARMONY group has found that the methods used in this study differ in their availability and affordability to European centers involved in MRSA surveillance. Here, we demonstrate that the integration of such technologies is achievable, although common protocols (such as we have developed for PFGE) may also be important, as is the use of centralized Internet sites to facilitate data analysis. PFGE and spa-typing data from analysis of MRSA isolates from the many centers that have access to the relevant equipment can be compared to reference patterns/sequences, and clonal designations can be made. In the majority of cases, these will correspond to those made by the (more expensive) method of choice—MLST/SCCmec typing—and these alternative methods can therefore be used as frontline typing systems for multicenter surveillance of MRSA. 相似文献
