Abstract
OBJECTIVE To describe the clinical characteristics, the reasons for initiating therapy, and the effects of treatment in the initial phase of evolocumab availability in lipid/internal medicine units in Spain. METHODS Retrospective, observational study, based on the medical records of consecutive patients initiating treatment with evolocumab (from February 2016 to July 2017) in 20 internal medicine units in Spain. A review was made of the demographic and clinical characteristics of the patients, the lipid lowering treatment, and the evolution of the lipid profiles between 12weeks pre-initiation and 12±4weeks post-initiation of evolocumab. RESULTS A total of 136 patients were analysed, of whom 64.0% were men, and the mean age (standard deviation, SD) was 56.6 (11.5) years. The large majority (75%) had familial hypercholesterolaemia (4 homozygous), and 51.0% of them had suffered at least one cardiovascular event. Atherosclerotic cardiovascular disease (ASCVD) was present in 61% of all patients. At initiation of evolocumab, 61.0% of the patients were taking high-intensity statins, and 60.3% were receiving ezetimibe. The mean (and SD) of LDL-C levels at initiation of evolocumab was 169.1 (56.6) mg/dL. The LDL-C was greater than 160mg/dL in 46.4% of patients, and ≥190mg/dL in 26.5%. During the observation period, evolocumab produced significant reductions in LDL-C of 55.7% (P<.0001), achieving mean values of 74.3mg/dL. At week12, more than half (53.8%) of patients achieved LDL-C levels <70mg/dL, and 26.9% <50mg/dL. CONCLUSIONS In the lipid/internal medicine units, evolocumab was mainly prescribed in patients with familial hypercholesterolaemia, with or without ASCVD. The initial use of evolocumab was in accordance with the guidelines of the Spanish Society of Arteriosclerosis (SEA) of 2016, with LDL-C levels being well above the recommended thresholds for treatment initiation. Evolocumab treatment in clinical practice reduced LDL-C levels by about 55%, a similar reduction to that reported in clinical trials. Most patients achieved LDL-C goals.

Abstract
SummaryEosinophilic synovitis (ES) is a rare disease described in human and veterinary medicine. Only three cases have been reported in the horse. A case of tarsocrural synovitis in an Hispano-Arabian gelding is presented in this report. The patient presented with severe joint effusion and lameness of the right tarsocrural joint on admission. Synovial fluid analysis revealed an increased WBC of 12800 leukocytes/microliter with 76% of eosinophils. Lavage of the diseased joint and medical treatment with antibiotics and non-steroidal anti-inflammatory drugs produced remission of the clinical problem.

Abstract
Breast cancer is common with over 230,000 new cases diagnosed each year in North America alone. While great strides have been made to achieve excellent cancer control and survival, a significant minority of patients fail locally. While initial salvage to regain disease control is of the utmost importance, it is not universally successful. This leads to a therapeutic quagmire. Additional surgery, radiation and chemo-hormonal therapy are possible, but they are usually highly morbid with low success rates. Photodynamic therapy appears to be an underutilized salvage modality for this unfortunate patient population. This report analyzes and reviews the role of photodynamic therapy for patients with chest wall re-recurrence from breast cancer.

Abstract
The aim of this study was to evaluate the use of whole-body plethysmography as a non-invasive method to determine the respiratory parameters and profiles in two tortoise species belonging to the genus Testudo. Pulmonary functions and volumetric parameters were determined in 10 adults of Testudo hermanni and in seven Testudo marginata animals, using whole-body plethysmography. A profile pattern was regularly observed: an inspiratory flow peak, an expiratory peak, an apnoea phase and a second expiratory peak, previous to the beginning of the next respiratory cycle. Positive and significant correlation was observed between the inspiratory time, weight and length of the tortoises. Larger tortoises showed a higher time of inhalation. The peak of inspiratory flow was correlated with the sex, being longer in the females. T. marginata had an inspiratory time longer than that of T. hermanii. In T. hermanii, differences related to the sex were observed in the tidal volume, peak inspiratory flow, peak expiratory flow, expiratory flow of 50 per cent and enhanced pause, which could be related to the smaller size of males. The results suggest that additional information on new technologies currently used in pet medicine or even in human medicine should be developed and adjusted as alternative ways to support the rehabilitation of turtles and tortoises.

Abstract
In 2005 and 2006 an outbreak of disease associated with border disease virus (BDV) infection caused high mortality in the Pyrenean chamois (Rupicapra pyrenaica) in the Catalan Pyrenees (NE Spain). The aim of this study was to determine values for different haematological and serum biochemical analytes in 32 free-ranging Pyrenean chamois affected by the disease and to compare them with those obtained from healthy chamois. In the affected chamois red blood cell counts, haemoglobin concentrations, packed cell volumes, mean corpuscular volumes and lymphocyte counts were all lower, while the neutrophil and platelet counts were higher. Glucose, lactate, triglycerides, creatinine, total protein concentrations and alkaline phosphatase activity were also lower, in contrast to the concentrations of total bilirubin, urea and aspartate aminotransferase activity, which were higher. Most of the observed changes could be associated with cachexia and inflammation in the affected chamois. Lymphopenia could be directly related to the BDV, which would lead to immunosuppression and explain the high rate of secondary infection observed in these animals.

Abstract
Ingesta passage times of soft flat foam dishes and gastric emptying time of barium-impregnated polyethylene spheres (BIPS) were measured in 22 and 8 loggerhead sea turtles (Caretta caretta), respectively. Transit time (T(1)) was considered as the time between ingestion and first elimination, and retention time (T(50)) and total transit time (T(85)) the expulsion time of 50% and 85% of the markers, respectively. The experiments were carried out at different times of the year and water temperature was recorded. A set of dorso-ventral radiographs was taken to locate the BIPS, and the gastrointestinal anatomy of 5 dead turtles was studied to help with interpretation of the radiographs. No significant correlation was observed between T(1), T(50), T(85) and minimum straight carapace length (SCLmin) or body mass and no statistical difference was found in ingesta passage transit times between juvenile (n = 6) and sub-adult turtles (n = 16). Mean passage times of the dishes (in days) were: T(1) = 9.05, T(50) = 12.00 and T(85) = 13.19. Gastric emptying time using BIPS was 24-48 h. The transit time (T(1)) for the BIPS was longer (13.25 +/- 4.86 days) than the foam markers (8.5 +/- 2.73 days) in 8 turtles studied simultaneously. Although the total transit time tended to be faster in turtles submitted to water temperatures between 20 degrees C and 23.6 degrees C no significant correlation was observed between T(1), T(50) and T(85) and the temperature.

Abstract
Twenty live and five dead juvenile and subadult loggerhead sea turtles were examined ultrasonographically. Ten soft tissue areas of the integument were used as acoustic windows: cervical-dorsal and cervical-ventral, left and right cervicobrachial, left and right axillary, left and right prefemoral and left and right postfemoral windows. Anatomical cross-sections were performed on the dead turtles to provide reference data. The fourth and fifth cervical vertebrae, the spinal cord, and the venous sinuses of the external jugular vein were clearly visible through the cervical-dorsal acoustic window, and the oesophagus and the heart were imaged through the cervical-ventral acoustic window. The stomach was more frequently visible through the left axillary acoustic window. The liver could be imaged through both sides, but the right axillary acoustic window was better for visualising the gall bladder. The large and small intestines and the kidneys were visible through the right and left prefemoral acoustic windows; the kidneys were easily identified by their intense vasculature.

Abstract
BACKGROUND AND OBJECTIVES Twenty-seven patients with refractory liver metastases from colorectal cancer took part in a Phase II study of the light infusion technology (Litx) light-activated drug/device system to assess safety and evaluate time to tumor progression (TTP). METHODS Litx consists of the light-activated drug, talaporfin sodium (LS11), activated intratumorally by a catheter-like array of light-emitting diodes (LEDs). After placement of the array via ultrasound or computed tomography (CT) guidance, LS11 was administered intravenously, followed 15-60 min later by light infusion for 2.8 hr. Patients were assessed for adverse events and tumor response using physical examination, laboratory values, and CT scan evaluation over a period of 60 days. RESULTS The observed occurrence of Litx treatment-related adverse events was minimal and cumulative toxicity did not occur when combined with chemotherapy. Assessment of TTP and tumor response rate, although statistically non-robust, suggest potential improvement. CONCLUSIONS The Litx system was shown to be safe for treating liver metastases from colorectal cancer and there was no cumulative toxicity when combined with standard systemic therapy. Preliminary assessments of TTP and tumor response rate justify further evaluation in a Phase III follow-up study.

Abstract
The aim of this study was to determine the normal computed tomography (CT) appearance of the vertebral column and coelomic structures of the loggerhead sea turtle (Caretta caretta) and to use three-dimensional (3D) and multiplanar reconstructions to indicate the position of each organ in relation to the vertebrae and carapace. Transverse sections of 1mm thickness were performed in seven clinically healthy and in five dead loggerhead sea turtles using multi-detector CT equipment. A computer workstation was used for multiplanar and 3D reconstructions. Dead turtles were frozen and sectioned in the transverse, dorsal and sagittal planes to compare the anatomical structures' appearance with CT images. Clinically relevant organs including the oesophagus, stomach, trachea, bronchi, lungs, liver, gallbladder, heart, spleen, kidneys and vertebral canal were identified in CT images. Computed tomography provides detailed information on the respiratory system and skeleton; the location of the coelomic structures with respect to the carapace and the vertebrae that is provided in this work will facilitate the use of other ancillary diagnostic techniques such as ultrasound, radiography and biopsy, thereby improving safety of access in surgical procedures.

Abstract
The object of this study was to examine the erythrocytes, leukocytes and thrombocytes of the giant lizard of El Hierro (Gallotia simonyi) by light and electron (TEM) microscopy, and cytochemical staining. Smears were prepared from blood from the ventral coccygeal vein of 10 healthy adult lizards (five males and five females) from the Giant Lizard of El Hierro Reproduction and Research Centre, Canary Islands, Spain. The cytochemical stains used were: benzidine peroxidase (BP), chloroacetate esterase (CAE), alpha-naphthyl acetate esterase (ANAE), acid phosphatase (AP), periodic acid-Schiff (PAS), toluidine blue (TB) and May-Grünwald-Giemsa (MGG). Electron microscopy was also performed on all samples. Heterophils had granules that were heterogeneous in both size and electron density, and stained with BP, PAS and ANAE. Eosinophil granules were homogeneously electron-dense and stained for AP, CAE and ANAE. Basophils had both highly and moderately electron-dense granules, and stained with TB and ANAE. Azurophil granules were of low electron-density and stained for AP, CAE and ANAE. Azurophil cytoplasm was vacuolated on TEM. The cytoplasm of lymphocytes contained many ribosomes and was positive for AP. Monocytes had a large nucleus and a vacuolated cytoplasm but did not stain by any of the cytochemical methods used. Thrombocytes had a relatively large nucleus but little cytoplasm; they did not stain cytochemically. The blood cells of the giant lizards of El Hierro differ from those of other members of the Order Squamata both morphologically and cytochemically. The variation in cytochemical responses in the blood of reptiles makes it necessary to study species individually if meaningful clinical decisions are to be made.

Blood samples were taken from the ventral coccygeal vein of 15 El Hierro giant lizards (Gallotia simonyi) (seven females and eight males), six La Gomera giant lizards (Gallotia bravoana) (four males and two females) and four Tenerife giant lizards (Gallotia intermedia) (two males and two females), and 31 blood parameters were measured. Among the haematological parameters there were significant differences between the three species in heterophils, azurophils and lymphocytes, but no significant differences in red blood cell count, white blood cell count, haemoglobin, packed-cell volume, monocytes, eosinophils and basophils. In terms of blood chemistry there were significant differences between the three species in cholesterol, triglycerides, glucose, sodium, chloride, urea, uric acid, total proteins, prealbumin, albumin and gamma globulins, but no significant differences in calcium, potassium, aspartate aminotransferase, alanine aminotransferase, creatine kinase, bile acids, alpha-1 and alpha-2 globulins and beta globulins.

Abstract
OBJECTIVE To evaluate the cytological and microbiological contents of guttural pouch washes of ten randomly selected horses restrained so as to prevent them lowering their heads, and to assess the possible effects on the guttural pouch environment in these horses. PROCEDURE Cytological and microbiological studies were performed on guttural pouch washes of ten clinically normal horses restrained in a standing position so as to prevent them from lowering their heads below normal, as would happen during transportation on long journeys. They were restrained for 12 or 24 h and cytological, bacteriological and mycological findings in guttural pouch washes were recorded. RESULTS The cytological gradings and neutrophil concentrations of guttural pouch washings were higher in horses that had their heads restrained for a longer period. Washings from these horses were more likely to contain cultivable bacteria and were the only washes yielding potentially pathogenic bacterial species. CONCLUSION Variation in the cytological differential counts and bacterial cultures of guttural pouch lavages may be found in clinically normal horses which have had their heads restrained in an elevated position for periods from 12 to 24 h. This should be considered when examining this site and care must be taken when interpreting cytology of guttural pouch lavages in samples taken after transportation for more than 12 h. Restriction of head movement could also affect the normal pouch enviroment and predispose it to disease.

Abstract
Percutaneous washes of the guttural pouches were obtained from two groups of 15 clinically normal horses, one lightly exercised and the other heavily exercised. Microbiological and cytological studies showed a wide variation in the differential cell counts. The cytological pattern of the normal lavages (< 5 per cent neutrophils) was characterised by a large proportion of ciliated columnar epithelial cells, a few non-ciliated cuboidal epithelial cells, and less than 1 per cent monocytes, lymphocytes, and eosinophils. Abnormal lavages (with more than 5 per cent neutrophils) had higher levels of bacterial growth than normal lavages. There were significant differences between the bacterial growth and total cell count, and also between the neutrophil contents of the lavages from the two groups of horses.

Abstract
In an effort to define the effect(s) of lithium heparin and tripotassium EDTA on various hematologic parameters in Testudo hermanni, we collected blood samples from 29 clinically healthy adult individuals of both sexes. Portions of each blood sample were transferred to tubes containing either lithium heparin or tripotassium EDTA. The following determinations were made on samples of blood from each anticoagulant: red and white cell counts, packed cell volume, hemoglobin concentration, red cell indices, and differential white cell counts. Due to hemolysis, hematocrits could not be determined from blood samples in EDTA. Further, red blood cell counts were lower in the EDTA samples than in the heparin samples, again due to hemolysis associated with EDTA. However, EDTA did not appear to interfere with hemoglobin determinations. Heparin blood samples provided more optimal blood smears than did EDTA samples, thus differential leucocyte counts were determined only from smears taken from heparin blood samples. Further, thrombocyte and leucocyte aggregation was not observed with heparin use. Thus, heparin is considered the anticoagulant of choice in chelonians for determining red blood cell counts, erythrocyte indices, and hematocrits. When May-Grunwald-Giemsa stain was compared with Diff-Quick, thrombocytes could be more easily differentiated from lymphocytes using the May-Brunwald-Giemsa stain. Heterophil granules seemed to coalese more when Diff-Quick was used. Eosinophils, basophils, and monocytes were similar in appearance with both staining methods.

Abstract
A semiautomatic electronic blood cell counter (Sysmex F-800) was evaluated with equine blood, according to the protocol of the International Committee for Standardization in Haematology (ICSH, 1984). The precision and overall reproducibility were acceptable for all the parameters studied except for the platelet count, in which a coefficient of variation of 18.8% and 21.7% was obtained for within and between batch precision and 26.76% for overall reproducibility. Carry-over for the haematocrit value and platelet count was unsatisfactory, thus the use of a blank diluent sample between different analyses was necessary. Linearity of the analyser was acceptable in the range studied. A total of 100 equine blood samples were studied with the Sysmex F-800 and the manual method. The correlations between both Methods were acceptable for all the parameters. In the storage study, the red blood cell count and the haemoglobin concentration were the parameters with longest stability (72 h) at 4 degrees C and 25 degrees C. Platelet count decreased significantly at 3 h post-extraction in those samples stored at 4 degrees C. During the evaluation period, Sysmex F-800 was easy to handle and it is well suited for routine equine blood cell analysis.

Abstract
Twelve clinical biochemical parameters were determined in 97 animals of all age groups and both sexes of the endangered Catalonian donkey breed. Significant sex differences were observed for phospholipid concentration (P<0.01). Evaluating the effect of management practices on the various parameters showed significant differences for total bilirubin (P<0.001) and creatinine (P<0.05) concentrations and gamma-glutamyltransferase (P<0.05) activity. Moreover, it was observed that inorganic phosphorus concentration decreased with age (P<0.001), whereas albumin and triglyceride concentrations increased with age (P<0.01 and P<0.001, respectively). Comparison of biochemical ranges obtained for the Catalonian donkey breed with reference ranges for other breeds and populations (Mammoth, USA donkeys, UK donkeys, Indian donkeys and Poitou donkeys), indicated that most values were similar, with the exceptions of enzymatic activities mainly. The results reported in the present study could serve as reference ranges for donkey populations.

Abstract
PURPOSE To evaluate the intraoperative, postoperative, and long-term complications of an absorbable pelvic mesh sling after surgery for rectal carcinoma. METHODS A retrospective review of medical records from April 8, 1991, through April 8, 1996. RESULTS Twenty patients with a mean age of 57 (range, 37-79) years underwent pelvic mesh sling placement. The tumor stages were as follows: Stage I, 5; Stage II, 2; Stage III, 11; and Stage IV, 1. A recurrent perianal basal cell carcinoma was not included in the staging group. Surgery consisted of 18 abdominoperineal resections, 1 total proctocolectomy, and one Hartmann's procedure. Mean follow-up was 18 (range, 2-49) months. There were no intraoperative complications related to mesh placement. Twenty-nine complications occurred in 14 patients during the immediate postoperative period. Five were possibly mesh-related and included a pelvic abscess, perineal seroma, toxic perineal wound, pulmonary embolus, and lower extremity deep venous thrombosis, respectively. A mild postoperative ileus developed in 17 patients (85 percent), and a diet was initiated at a mean of seven (range, 4-24) days. Fourteen patients received postoperative radiotherapy with a mean dose of 5,339 (range, 2,500-7,020) cGy delivered in 180-cGy fractions. There were 14 immediate complications caused by radiotherapy in 11 patients, but only two patients required delays in treatment. Two patients had diarrhea alone, six developed perineal dermatitis alone, and three patients had both diarrhea and perineal dermatitis. All patients with diarrhea had received chemoradiation. One patient developed a partial small-bowel obstruction following radiation. CONCLUSIONS Absorbable pelvic mesh sling placement can be performed with minimum morbidity and is recommended following surgery for rectal cancer when radiation is anticipated as part of multimodality therapy.

Abstract
The human interleukin-2 (IL-2) gene was successfully delivered into established human tumor xenografts in SCID (severe combined immunodeficient) mice by cationic liposome-mediated DNA delivery. A bicistronic mammalian expression vector containing a reporter gene (beta-galactosidase) and human IL-2 cDNA was complexed with either lipofectin or DC-cholesterol liposomes and transferred to tumor xenografts by direct intratumoral injection. Transfection of tumors was confirmed by staining of tumor sections for beta-galactosidase activity and by reverse transcription-polymerase chain reaction (RT-PCR) for the presence of IL-2 mRNA. Growth suppression of tumor xenografts was observed in animals injected with plasmid-liposome complexes but not in animals that received liposomes or naked plasmid only. Complete tumor regression, mediated by the mouse natural killer cells, was observed in 50-80% of the mice treated with the plasmid containing the IL-2 cDNA. The effectiveness of the treatment was dependent on the transfection efficiency and the tumor size at the start of therapy. An initial IL-2 independent suppression of tumor growth was also observed with a plasmid carrying only the beta-galactosidase gene but this effect was temporary and did not lead to tumor regression. These results establish that human tumor xenografts growing in SCID mice can be transfected in vivo by liposome mediated gene delivery and that both IL-2-dependent and IL-2-independent factors may contribute to the tumor suppression observed here.

Abstract
BACKGROUND & AIMS Helicobacter infection of the gastric antrum is responsible for a number of gastric disorders. Antibiotic therapy is lengthy and is not always effective. It has been shown previously that oral immunization against Helicobacter felis in mice can prevent colonization after challenge. The aim of this study was to investigate the efficacy of therapeutic immunization in eradicating an established Helicobacter infection and in reducing gastritis. METHODS Domestic ferrets, confirmed to be infected with Helicobacter mustelae by gastric endoscopy, were orally immunized with varying doses of purified Helicobacter pylori urease in combination with the mucosal adjuvant cholera toxin. Ferrets were assessed 1 week and 6 weeks after treatment for infection and pathology. RESULTS Therapeutic immunization eradicated Helicobacter colonization in 30% of all immunized ferrets, although there was no difference in efficacy between the varying doses of antigen tested. The difference was statistically significant when compared with animals administered cholera toxin alone or buffer (P = 0.04). The intensity of inflammation was also significantly reduced in immunized animals (P = 0.0003). CONCLUSIONS Oral immunization with purified H. pylori urease and cholera toxin can eradicate H. mustelae in a natural host pathogen model. Oral immunization of chronically infected animals markedly reduced gastric inflammation.

Abstract
Systemic aspergillosis was diagnosed in a two-and-a-half-year-old spayed German shepherd dog which had suffered an acute attack of paralysis of the pelvic limbs. The neurological deficits were attributed to the destruction of the seventh vertebral body and the intervertebral disc, with protrusion of necrotic material into the vertebral canal and compression of the spinal cord at this level. Microscopically, fungal invasion and destruction of the body of T-7 was observed and Aspergillus species were identified. Fungal granulomas were also found in the liver, lung, spleen and mesenteric lymph nodes.

Abstract
The case is reported of a patient who developed a vertebral osteomyelitis caused by Enterobacter cloacae. The organism was isolated in cultures of blood and vertebral puncture biopsy samples. The patient was satisfactorily treated with trimethroprim and sulphamethoxazole. Enterobacter cloacae, a Gram negative organism, has been confirmed as the cause of bacteremia in patients with burns, urinary infections, in adults with pneumonia, and in children with joint infections. Spondylodiscitis caused by Enterobacter cloacae has not previously been described.

Abstract
The agar dilution method was used to determine the inhibitory activities of 28 antimicrobial agents against 35 strains of the genus Peptostreptococcus, 4 strains of the species Peptococcus niger, 20 strains of the species Megasphaera elsdenii, 7 strains from the species Acidaminococcus fermentans, 8 strains of the genus Clostridium, 11 strains of the genus Eubacterium, and 1 strain of the species Propionibacterium acidipropionici, all of which were isolated from 125 clinical cases of ovine foot rot between January 1987 and December 1988. The three unreidopenicillins studied proved to be the most active antimicrobial agents, with a high percentage of strains being susceptible at a concentration of 64 micrograms/ml. Penicillin G, ampicillin, and the three cephalosporins studied also had good activity. Fosfomycin showed a high degree of activity among the 116 anaerobic bacteria tested.

Abstract
The presence of anticardiolipin antibodies (aCL), von Willebrand factor activity and platelet function was studied in 35 patients with systemic sclerosis (SSc) scleroderma and 22 healthy controls. aCL positivity was observed in no patient with SSc or controls, whereas beta-thromboglobulin and platelet factor 4 levels were significantly higher in patients with SSc (p less than 0.001 and p less than 0.002, respectively). Furthermore, plasma from patients with SSc had a greater degree of aggregation to adenosine diphosphate 1 microM (p less than 0.05) but not to collagen or arachidonic acid. The plasma of patients with scleroderma also had increased von Willebrand factor activity compared with controls (p less than 0.001). We conclude that aCL appears not to play a central role in the pathogenesis of vascular and hemostatic alterations in SSc.

Abstract
BACKGROUND The changes of nailfold capillaries detected by capillary microscopy is a characteristic frequently observed in systemic sclerosis. The relationship between the different capillary microscopic changes and clinical manifestation, organic disease and disease progression were studied. METHODS Sixty-three patients were studied in whom capillary microscopy was performed and organic disease was determined by analytical and morphological examination. The presence of association between the capillary microscopic signs and clinical manifestation and disease progression were investigated by the chi-square and Fisher tests. RESULTS Capillary microscopic alterations were found in 95% of the patients. The extense capillary loss was associated as statistically significant to the diffuse form of scleroderma. Statistically significant associations were not found between the different capillary microscopic signs and disease progression and organic disease (global and individual per each organ). CONCLUSIONS Although capillary microscopic changes are present in most scleroderma patients they are not useful in the evaluation of organ involvement of the disease. The presence of extense capillary loss is linked to worse prognosis in its association to the diffuse form of scleroderma.

Abstract
A series of 31 patients suffering idiopathic inflammatory myopathy (IIM); we describe the extramuscular manifestations, specially pulmonary, the association to neoplasia, the histopathological characteristics, and their response to treatment. Fourty three percent of IIM patients presented a pulmonary involvement, 9% presented an associated neoplasia. The histopathological study allowed us to clearly differentiate dermatomyositis and polymyositis within IIM. 65% of patients initially responded to glucocorticoids and the most usefull therapeutic alternatives were azatioprine and cyclosporin-A.

Abstract
We evaluated platelet function in 59 patients with Raynaud's phenomenon (RP): 24 had primary RP (PRP) and in 35 RP was associated with diffuse scleroderma (DS). In the group with PRP there were 10 males and 14 females, with a mean age of 43 +/- 12 years and a time of evolution of 5 +/- 5 years. In the group with RP associated with DS there were 31 females and 4 males with a mean age of 53 +/- 12 years and a time of evolution of 9 +/- 7 years. The control group consisted of 20 healthy individuals (14 males and 6 females with a mean age of 40 +/- 12 years). In all patients and controls beta-thromboglobulin (BTG) and platelet factor 4 (PF4) levels were measured in plasma, and platelet aggregation was evaluated in the presence of adenosine diphosphate (ADP), collagen and arachidonic acid. The patients with RP associated with DS had BTG and PF4 higher than those with PRP and controls (p less than 0.02). The BTG/PF4 ratio was also significantly greater in patients with DS (p less than 0.005). The platelets from patients with DS had a greater aggregation with ADP (1 microM and 0.5 microM) than those from PRP (p less than 0.03). We concluded that patients with RP associated with DS had in vivo activation and a greater aggregation of platelets, in contrast with the absence of these findings in the group with PRP and in controls.

Abstract
The classical rhinoplasty techniques do not give the best results when used on thick skin noses. We have developed a new technique, apex columellar cartilage graft, for correcting nasal tip projection in thick skin noses.
