Peripheral Reconstructive Lamellar Keratoplasty for Late Ectasia After Penetrating Keratoplasty in Keratoconus Eyes.

Purpose: To describe outcomes of customized peripheral anterior lamellar keratoplasty (PALK) for late ectasia of the donor-recipient junction after penetrating keratoplasty (PK) for keratoconus.

Methods: This was a single-center, retrospective review of 33 eyes (28 patients) that developed ectasia restricted to the graft-host junction; 17 eyes underwent PALK using lamellar resections of 8- to 11-mm width starting at the external margin of the previous PK and suturing a same-size donor graft (annular or segmental). Five eyes were excluded from analysis because of postoperative complications unrelated to the technique.

[Anorectal manifestations of sexually transmissible diseases. Kaposi's sarcoma].

The proctologist is above all concerned with the known recrudescence of venereal diseases. Examples reviewed are diseases of bacterial origin (syphilis, gonorrhea, soft chancre, donovanosis and chlamydiosis), appropriate antibiotic therapy and diseases of viral origin (herpes, condyloma acuminatum). Also noted are other bacterial, viral and parasitic diseases and, indeed, cancers of which Kaposi's sarcoma is the example, even though these are not manifested anorectally.

[Syndrome of inappropriate antidiuretic hormone secretion. A report of two cases with hyponatremia and hypouricemia].

Two cases of Schwartz-Bartter syndrome are reported. Both were due to malignant anaplasic tumours of the APUD type with multiple abnormal endocrine secretion, and both were accompanied with hypouricaemia of uncertain significance. The authors believe that the association of hypernatraemia with hypouricaemia should alert clinicians to the possibility of a syndrome of inappropriate antidiuretic hormone secretion (SIADH) of malignant origin.

[Gastrointestinal haemorrhage in the cirrhotic. The value of injectable posterior pituitary extract (author's transl)].

The authors report the experience which the have acquired since 1970 in the use of posterior pituitary extract as part of the treatment of gastrointestinal bleeding in cirrhotics. 100 cases have been collected, in 73 patients. These may be divided into two groups: one of 32 patients, who did not receive posterior pituitary extract, with 31 deaths, and one of 41 patients who did receive the extract, with 6 deaths.

[The excision of villous tumours of the rectum via a trans-sphincterian anal approach (author's transl)].

Cleavage in the thickness of the internal sphincter and of the circular layer of the rectum is performed. By progressive drawing down, this method makes it possible to obtain complete excision, passing at a distance from the tumour in its different planes.
