A new ruthenium black dye design with improved optical properties for transparent dye sensitized solar devices.

We report here on the preparation and on the electronic properties of a panchromatic Ru(ii) sensitizer based on a new ligand which allows for higher molar extinction coefficients in the visible and better performances (32% efficiency improvement) over conventional "black dye" in transparent DSSC.

[Suture threads in the pathology of the operated stomach]. / I fili di sutura nella patologia dello stomaco operato.

Endoscopy following operations on the stomach showed inflammation or ulceration attributable to no-absorbable suture threads in a number of cases. The pathogenetic and clinical features of this picture are described. Complete remission was obtained after endoscopic removal of the foreign body.

[Post-traumatic stenosis of the small intestine]. / La stenosi post-traumatica del tenue

A case of intestinal stenosis in a subject who had received an abdominal injury four weeks earlier is presented. The relevant literature is surveyed and the pathogenesis of this unusual condition is examined. Post-traumatic stenosis of the small intestine is seen as an example of ischaemic stenosis.

[Repair of inguinocrural hernias with subperitoneal prostheses]. / La riparazione delle ernie inguino-crurali recidive con protesi sottoperitoneali.

An original technique for the repair of recurrent inguinocrural hernia destruction of the inguinal ligament is presented. A prosthetic lamina is applied in the subperitoneal space against the deep fascia of the inguinocrural musculature. It is held in place by intra-abdominal pressure and ordinary stitches. The subumbilical median route is used and the peritoneum and hernia sac are stripped from the abdominal wall.

[The axillo-axillary bypass]. / Il by-pass axillo-axillare.

Personal experience with two cases of symptomatic occlusion of the subclavian artery treated with axillo-axillary by-pass is reported. The operating technique, in which the second portion of the axillary artery and a dacron blood conductor are employed, is described and the various transthoracic and extrathoracic operations that have been proposed are reviewed along with the advantages and disadvantages of each. It is concluded that axillo-axillary by-pass is a simple solution for a complex haemodynamic, clinical and therapeutic problem.

[Internal hernia through an orifice of the broad ligament of the uterus]. / Ernia interna di un orificio del legamento largo dell'utero.

A case of hernia-induced occlusion of the small intestine through an orifice of the broad ligament of the uterus is reported. After reviewing the literature, the pathogenetic aspects are considered, with reference to the congenital or acquired origin of the defect. Clinically, the most significant factors for diagnosis are the patient's multipara condition, previous obstetrico-gynaecological operations, signs of mechanical type intestinal occlusion and palpation of a parauterine mass. Surgical treatment involves straightforward mechanical ileus with repair of the occluding orifice.

[Current trends in the therapy of bleeding duodenal ulcer]. / Orientamenti attuali di terapia nell'ulcera duodenale sanguinante.

A distinction is drawn between two main groups of patients with continuous and massive haemorrhage respectively in bleeding duodenal ulcer, and the criteria upon which this distinction is based are described. The two main types of surgery proposed for the treatment of this complication of duodenal ulcer (vagotomy and gastric resection) are examined. The conclusion is drawn that vagotomy (truncular with drainage, or superselective with or without drainage) is to be preferred to gastric resection in the light of personal experience, and with particular reference to operative mortality and the recurrence of haemorrhage and ulcers.

[Perforated duodenal ulcer. Personal experience]. / Ulcera duodenale perforata. Nostra esperienza.

Reference is made to personal experience in affirming that the treatment of perforated duodenal ulcer should set out to resolve both the perforation and the ulcer at the same time. Troncular vagotomy combined with pyroloplasty is put forward as an effective way of achieving this, and long-term results on a par with those obtained electively are described.

[Isolated rupture of aneurysm of the internal iliac artery]. / Rottura isolata di aneurisma della arteria ipogastrica.

Isolated aneurysms of the internal iliac artery are rare and often asymptomatic. They are frequently diagnosed as a result of complications such as rupture. The authors describe in detail two cases of ruptured aneurysms of the internal iliac artery treated by emergency surgery with no perioperative mortality or morbidity.
