Further experience with the posterior interosseous flap.

This paper describes and discusses some of the clinical applications of the posterior interosseous forearm flap in hand reconstruction, including the fact that larger areas of skin than previously reported can be used safely. It is based on a series of 21 patients, 50 anatomical dissections and 10 injection studies.

Bricanyl Turbuhaler and Ventolin Rotahaler in exercise-induced asthma in children.

Bricanyl Turbuhaler (0.5 mg terbutaline sulphate) and Ventolin Rotahaler (0.4 mg salbutamol) were compared in a randomized double-blind placebo controlled study on exercise-induced asthma in 19 children (14 boys) aged 7-14 years.

Viability of Ascaris lumbricoides eggs eliminated after anti-helminthic therapy.

The viability of Ascaris lumbricoides eggs passed in the feces was evaluated after treatment of patients with one of the anti-helminthic drugs (thiabendazole, levamisole, cambendazole, pyrantel pamoate, mebendazole or praziquantel). For each drug, a group of 5 children was selected and their feces collected 24 h before treatment and 24, 48 and 72 h after drug administration, except for mebendazole, with the feces being collected throughout the period of treatment. After sedimentation, the total amount of eggs from each collection was transferred to tissue culture flasks containing 10 ml H2SO4 0,1N, with the addition of 3 drops of a miconazole solution, and incubated at 28 degrees C, individually, for 80 days.

[Partial vertical laryngectomies and reconstruction with plathysma myocutaneous flap].

The authors report on 14 patients with epidermoid carcinoma of the glottic region, classified T1, T2 and T3, operated upon by a hemilaryngectomy (9 cases) with reconstruction using a Plathysma myocutaneous flap. The oncological results over a follow-up period of 1 to 6 years and the functional results are analyzed. The authors conclude that this method does not compromise the carcinological result and provides a good functional result with low ratings for complications, with in addition an adequate support for the organ, favouring increased resections.

Prevalence of Cooperia punctata, C. pectinata and C. oncophora infections in dairy calves in Brazil.

Cooperia is the most prevalent helminth parasitizing calves in Brazil. Three species of this genus occur most often: C. punctata, C.

Patient management following uncomplicated elective gastrointestinal operations.

The management of patients after uncomplicated elective gastrointestinal operations is frequently left to junior members of the surgical team once they have learnt their seniors' regimens. The use of nasogastric (N/G) tubes, the volume of intravenous (IV) fluid replacement and the reintroduction of oral fluids and solids are topics not generally covered in the surgical textbooks and so are learnt in hospital. A postal survey of all consultant general surgeons in Scotland was conducted to assess the variations in management of patients after cholecystectomy, right haemicolectomy and sigmoid colectomy.

[The study of Ascaris lumbricoides in the laboratory].

With the purpose of standardising techniques for the laboratory study of Ascaris lumbricoides, faeces were collected from children parasitised by A. lumbricoides, during a 24 hour period. The fecal samples were sieved and resuspended several times in water.

[Mycobacteria isolated from armadillos Dasypus novemcinctus inoculated with mycobacterium leprae].

The authors report the isolation of two mycobacteria from armadillos livers and spleens, inoculated with Mycobacterium leprae in the Kato medium. They discuss this results.

[Comparative study of various staining methods for mycobacteria].

The present paper intends to show what coloration method for mycobacteria is the better. Samples was assessed and processed by hot Ziehl-Neelsen, cold Ziehl-Neelsen, Ziehl Gabbet and Ziehl-Neelsen with alkaline metilene blue. After microscopy by five different persons the method selected were the cold Ziehl-Neelsen.

The distally based island posterior interosseous flap.

The posterior interosseous vessels give a significant contribution to the fascial plexus which supplies the skin of the forearm. This vascular arrangement forms the basis for an island fasciocutaneous flap which can be based either proximally or distally. Twenty-two dissection studies have been carried out to demonstrate the vascular anatomy of the posterior interosseous artery and its contribution to the fascial plexus.

Thumb reconstruction by the posterior interosseous osteocutaneous flap.

An island osteo-fasciocutaneous flap, based on the posterior interosseous vessels, is described for thumb reconstruction. The artery supplies the fascial plexus of the posterior forearm as well as the superficial and deep extensor muscles. A vascularised bone segment of the upper third of the ulna can be harvested, including a cuff of the extensor pollicis longus muscle.

Venous skin flaps: an experimental study and report of two clinical distal island flaps.

An experimental study of saphenous flaps in 26 dogs is reported, which confirmed the work of Baek et al. (1985) that venous flaps can survive. In addition, it showed that venous island flaps could survive after division of the venous pedicle proximally or distally, or as free flaps, providing through flow was re-established by venous anastomoses.

Trypanosoma cruzi: advantages of isolating bloodstream trypomastigotes by the carboxy methyl cellulose method.

Bloodstream trypomastigotes were isolated from blood of A/Sn mice 7 d after infection with 10(5) Trypanosoma cruzi Y strain. Red blood cells were removed by centrifugation and hypotonic shock and platelets and leucocytes by passage through a carboxy methyl cellulose column. Binding of trypomastigotes to the resin was prevented by including 10% normal mouse serum in the eluting buffer.

A new distally based fasciocutaneous flap of the leg.

A distally based flap on the medial side of the lower leg is described. In ten cadaver dissections two perforating arteries from the posterior tibial artery were a constant finding and a flap has been designed based on these. It has been used successfully in four patients.

International dermatosurgery: use of medial plantar based skin flaps for correction of foot defects.

The recently described instep island flap can be used to restore foot tissue deficits, however, its usefulness is limited by the length of the neurovascular pedicle and by the small surface of the flap. This flap can also be used as a free or as a cross-foot flap. We describe our experience with 10 patients.

The radioimmunoassay of a carcinoembryonic antigen fraction.

A qualitative and clinical evaluation of a radioimmunoassay for a carcinoembryonic antigen (CEA) fraction in serum is presented. The technique shows cross-reactions with normal organs' extracts lower than 0.05% and a 0.
