The Triticeae genetic resources of central Italy: collection, evaluation and conservation.

One hundred and six landraces belonging to 7 species of the Triticeae tribe were collected in central Italy by DBVBA (Perugia University), DIBIAGA (Ancona University) and ARSSA (Abruzzo Region Agricultural Development Agency) in different individual and joint missions. A few accessions were supplied by private and other public organisations. Triticum dicoccum Schubler is the most widespread species, followed by T. aestivum L., T. monococcum L., T. spelta L., T. turgidum var. durum Desf., Secale cereale L. and Hordeum vulgare L. Besides the presence of landraces reproduced by farmers over generations, information related to on-farm management and to qualitative/organoleptic traits as well as information related to their local names, uses, traditions and social context was gathered during the missions. The majority of the accessions was characterised by morphological and phenological traits and molecular markers. This work shows the presence of morpho-phenologic and genetic differences among landraces and the importance of some species in the agricultural systems and food customs of the investigated area. Particularly for emmer three well distinct landraces are present, "Farro Italia Centrale", "Farro della Garfagnana" and "Farro Italia Meridionale". Other interesting and traditional landraces are the "Solina" common wheat in Abruzzo and the "Orzo mondo" naked barley in Marche. Most of the populations are still cultivated in marginal lands and under low input or organic agronomic conditions; nevertheless, in many cases, they are found near modern varieties in conventional agriculture systems. Moreover, the in situ (on-farm) conservation of Triticeae landraces in central Italy is strictly linked to elderly farmers.

Right ventricular bypass for palliation of cardiac sarcoma.

A 33-year-old woman with a nonresectable right ventricular sarcoma and pulmonary outflow tract obstruction underwent a right ventricular bypass operation for symptomatic relief. The patient had an uneventful recovery and was asymptomatic on discharge, without jugular plethora or hepatomegaly. We consider this procedure to be an excellent palliative treatment of malignant right ventricular obstructive symptoms for improving the patient's quality of life.

[A case of popliteal pseudoaneurysm caused by femoral exostoses].

A popliteal artery pseudo aneurysm secondary to compression by a bony exostosis is recorded to call attention to this unusual etiological mechanism in a 32 years old woman. Restoration of arterial continuity was achieved by resection of the pseudo aneurysm and end to end anastomosis of the artery. A review of the literature discloses 32 cases of popliteal aneurysms associated to bony exostosis.

[Juvenile kyphosis].

The Authors discuss the juvenile kyphosis, a relatively frequent but neglected pathology. They consider the two significant clinical pictures: postural kyphosis and Scheuermann disease with their clinical, radiographic and therapeutic aspects. In the first entity repeated controls, a correct bearing, physical training and sport are necessary. In the second the treatment is based on physiokinesitherapy and a modified Milwaukee brace for an average time of 21 months. Are considered in this paper 64 cases of Scheuermann disease treated between 1977 and 1982 by the Orthopedic Clinic of the University of Parma, with relative results, classified as positive.

[Continuous closed aspiration lavage in the prevention and treatment of bone infections].

The Authors report their experience on bone infection treatment by means of closed circulation and suction. After a brief history of the informing and applying principles of the method, they expose the results obtained in 41 cases of septic lesions of the skeletal system. Since the patients were treated about 6 years ago, it is therefore possible state the reliability and effectiveness of this therapy. thirty-one (31) exposed fractures, six (6) osteomyelitis and four (4) infected pseudoarthrosis are considered, with a positive result respectively in 87%, 84% and 75% of cases. Considering the initial gravity and the reasons of failure, the Authors conclude that the method, always associated to other surgical acts, is efficacious and finds a precise and precious collocation in the therapeutic outfit.

Osteosynthesis with valgus osteotomy in the primary treatment of subcapital fractures of the neck of the femur.

The authors report 25 consecutive cases of subcapital fracture of the neck of the femur treated by osteosynthesis and valgus osteotomy. The results at 3 to 5 years showed bony union in all cases with only 2 cases of ischaemic necrosis (8%). Since this complication is due to vascular damage inflicted at the time of fracture the authors suggest that valgus osteotomy, which is usually only done in cases of pseudarthrosis, is also applicable to recent fractures which have a high risk of non-union.

"De Novo" trisomy 20p with macroorchidism in a prepuberal boy.

A 9-year-old prepuberal boy with trisomy 20p syndrome and previously undescribed macroorchidism is presented. This is the second report of trisomy 20p originated "de novo" supporting a frequency rate of about the 10% for this etiological mechanism. Reviewing the most common clinical findings of all 19 previous patients, a typical phenotype with a recognizable face can be carried out in several cases. If prepuberal macroorchidism is confirmed in further patients, trisomy 20p could be taken into account in the differential diagnosis with the sex-linked syndromes with mental retardation and abnormal testicular increase.

[Incidence of scoliosis in adolescents of the schools of Parma].

The Author reports about a school screening which was taken during 1979-80 at Parma schools (2283 young people) with an average of 13 years. The inquiry has stated the reason for a request of a radiographic examination in 3,3 X 100 of these young people examined. It showed 14,87X1000 scoliosis over 10 degrees. The Clinical inquiry method (bending test) is used to point out the rotational prominence superior 5 mm, to asymmetry of size triangles, possible anomalies that may be found on the sagital plane (Kyphosis) or for excess of interior arts when superior 10 mm. The team was composed of two M.D. and six therapists; they were helped by the scolastic staff.

[Photographic moiré method for preliminary diagnosis of spine deformity (author's transl)].

Moiré topography is a biostereometric method which produces a three-dimensional image of the shape of the trunk. In structure scoliosis an asymmetry of the two halves of the back is seen. This method has been studied and the range of the asymmetry of the moiré pattern has been compared with clinical observations and X-ray findings in case with structural scoliosis. Because of the sensitivity of the moiré method an asymmetry of at least half fringe interval could be regarded as a positive result. All the observed asymmetries less than one fringe interval had a lateral deviation of the spine of less than 10 degrees according to Cobb when W-ray examined. The moiré method seems to be very suitable for the screening of structural scoliosis, owing to: 1) its ability to detect and document even small deformities by photography; 2) the simplicity of the technique; 3) the possibility of documenting the condition of the back for comparison with subsequent examinations; 4) non-invasive for the patient.

[Surgical treatment of fractures of the distal end of the femur].

After considering the anatomoclinical aspects of fractures of the distal third of the femur, the Authors analyse the classification of these fractures. Different types of fractures were reviewed and they discussed the best orthopaedic or surgical treatment needed. Surgical methods were studied regarding sopracondylar and intracondylar fractures, which present difficult problems of reduction, contention and consolidation. The 23 cases operated on in the last 2 years were discussed by the Authors.

Percutaneous nucleotomy according to Onik: indications and results in 76 cases.

The authors report their experience using the Onik technique for the treatment of disc herniation in 76 patients since 1990. Indications that are not always easy in relation to a correct application of the Onik protocol are discussed. It is believed that a reduction in intra-disc pressure is favorable also in the presence of partial expulsion of the nucleus, decreasing the tendency towards further alimentation of herniated material in the vertebral canal. The results allow us to affirm that it is possible to obtain benefits even in patients who are not held to be suited to use of the Onik protocol, with the exclusion of migrated hernias, with emphasis on the fact that the best results were obtained in protrusion-bulging in young patients with acute symptoms and clinical signs corresponding to the nerve root involved.
