Abstract
The Ehlers-Danlos syndromes (EDS) are a group of heritable, connective tissue disorders characterized by joint hypermobility, skin hyperextensibility, and tissue fragility. There is phenotypic and genetic variation among the 13 subtypes. The initial genetic findings on EDS were related to alterations in fibrillar collagen, but the elucidation of the molecular basis of many of the subtypes revealed several genes not involved in collagen biosynthesis or structure. However, the genetic basis of the hypermobile type of EDS (hEDS) is still unknown. hEDS is the most common type of EDS and involves generalized joint hypermobility, musculoskeletal manifestations, and mild skin involvement along with the presence of several comorbid conditions. Variability in the spectrum and severity of symptoms and progression of patient phenotype likely depend on age, gender, lifestyle, and expression domains of the EDS genes during development and postnatal life. In this review, we summarize the current molecular, genetic, epidemiologic, and pathogenetic findings related to EDS with a focus on the hypermobile type.

Abstract
We report here for the first time the presence of Ophelimus mediterraneus sp. n. in Mediterranean Europe. This species appears to be closely related to Ophelimus maskelli, a well-known invasive pest of Eucalyptus. Based on molecular (cytochrome oxidase I, 28S), morphological (multivariate ratio analysis) and bio-ecological investigations, our study gives unambiguous relevant criteria that allow the discrimination between these two species. A full description of O. mediterraneus sp. n. is also provided. The geographic distribution of O. mediterraneus sp. n. as well as its impact on Eucalyptus species needs to be more widely assessed since its presence may have been confused with O. maskelli in their sympatric introduced areas. Further investigations of potential parasitoids in the native area may thus be welcomed to evaluate classical biological control achievability.

Abstract
BACKGROUND This study aimed at determining the cumulative effect of daily anesthesia, using two drug regimens, over hematological and biochemical parameters. METHODS Blood samples were obtained from rhesus monkeys 20 minutes after intramuscular administration of ketamine or ketamine/medetomidine combination for three consecutive days and results were evaluated to determine their effect on hematological and serum biochemistry values. Statistical significance of drug, day, and interaction of these two variables were evaluated. RESULTS Drug effect resulted in a dramatic increase of aspartate aminotransferase and creatine kinase values. Day effect resulted in decreases of RBC, HCT, Hgb, and alkaline phosphatase but an increase of other biochemical parameters evaluated. The drug/day interaction effect was found to be -significant for RBC, platelets, aspartate aminotransferase, alanine aminotransferase, and creatine kinase values. CONCLUSION The results of our study suggest a cumulative effect of serial anesthesia and should be an important consideration when interpreting hematology and serum biochemistry in rhesus macaques.

Abstract
Even with the advancement of radiologic techniques, metastatic cancers can still be difficult to detect. In this study, 48 patients suspected of having occult metastases were studied by radioimmunodetection following the administration of 92.5 to 181.3 MBq of indium 111-labeled monoclonal anticarcinoembryonic antigen antibody. All but seven patients were thought to have metastatic colorectal carcinoma. In the majority of cases, physical examinations and computed tomographic scans had failed to detect a lesion. At least one lesion that was later proved to exist was detected in 34 of the 50 studies performed on these patients. Seven of eight patients with normal radioimmunodetection scans remain free of disease. One hundred one sites were detected overall; 60 were considered true-positive sites and 27 false-positive sites. Fourteen sites remained in question. Nineteen false-negative sites occurred. Radioimmunoimaging appears valuable for the detection of occult cancer where standard, noninterventional techniques have failed to detect the suspected disease.

Abstract
A surgical technique for reconstruction after subtotal orbital exenteration uses an autogenous dermis-fat graft. A musculocutaneous flap is advanced over the graft to provide the anterior vascular supply for the free dermis-fat graft. The periorbita and remaining orbital tissue provide the vascular supply posteriorly. This technique eliminates extensive skin grafting and delayed spontaneous healing. Wound healing is rapid and surgical morbidity is minimized. We have used this procedure in three patients with sebaceous gland adenocarcinoma, two patients with severe posttraumatic contracted sockets, and as a palliative procedure in one patient with a fungating choroidal melanoma and widespread metastasis.

Abstract
We performed instrumented measurement of anterior-posterior laxity of the knee in thirty-three cadaver specimens, 338 normal subjects, and eighty-nine patients with unilateral disruption of the anterior cruciate ligament. The test instrument was the Medmetric knee arthrometer, model KT-2000. We measured total anterior-posterior laxity, produced by anterior and posterior loads of eighty-nine newtons (twenty pounds), and the anterior compliance index. The total anterior-posterior laxity is composed of an anterior displacement and a posterior displacement; these are measured from a testing reference position, defined as the resting position of the knee after applying and then releasing a posterior load of eighty-nine newtons. The anterior compliance index is defined as the anterior displacement between an anterior load of sixty-seven newtons and one of eighty-nine newtons. All tests were performed with the knee held on a thigh support that placed the knee in 20 +/- 5 degrees of flexion. The mean anterior displacement at eighty-nine newtons was 5.7 millimeters in a group of normal subjects and 13.0 millimeters in a group of patients with a disrupted anterior cruciate ligament. Ninety-two per cent of the normal subjects had a left knee-right knee difference in anterior displacement of no more than two millimeters, while 96 per cent of the patients with a unilateral disruption of the anterior cruciate ligament had an injured knee-normal knee difference in anterior displacement of more than two millimeters. Ninety-three per cent of the normal subjects had a difference in the left-right compliance index of no more than 0.5 millimeter, and 85 per cent of the patients with unilateral disruption of the anterior cruciate ligament had a difference in the compliance index of the injured and normal sides of more than 0.5 millimeter.

Abstract
This study was undertaken to examine the immediate effect of continuous passive motion (CPM) on anterior cruciate ligament (ACL) reconstruction stability. Cadaver knees were tested with a knee arthrometer with the anterior cruciate intact and then with the anterior cruciate sectioned. One of three anterior cruciate reconstructions was then performed and stability was restored to the knee and it was again tested with the knee arthrometer. Stability was defined as being within 2 mm of the intact measurement. The three operations selected were the Marshall-MacIntosh "over-the-top," (OTT) a patellar bone-patellar tendon-tubercle bone (BTB) graft, and a semitendinosis reconstruction. The specimens were placed on a CPM device in a cooler at 38 degrees F and put through a range of motion of 20 to 70 degrees at 10 cycles per minute for 3 days. A success was less than a 2 mm increase in the post-CPM measurement compared to pre-CPM. All three bone-tendon-bone operations failed. The semitendinosis operation was successful in only three out of eight specimens. The OTT operation was successful in eight out of nine specimens. The possible reasons for success and failure are discussed. Because of the potential problems with failure of an ACL with CPM it is suggested that the particular technique being used for an anterior cruciate reconstruction be tested prior to it being used with CPM clinically.
