[Clinical experiences with timolol eye drops].

Three groups of chronic simple glaucoma (group I: newly adjusted patients; group II: previously satisfactorily pressure-regulated patients; group III: previously notsatisfactorily pressure-regulated patients) received treatment with Timolol eye drops for 4 months. In 34 eyes the intra-ocular pressure could be lowered below 22 mm Hg by Timolol alone, whereas 10 eyes additionally had to be treated with 1% epinephrine. The higher the initial pressure effect, the more pronounced the pressure-lowering properties of Timolol became. Especially in the first 2 weeks, less in the following 14 weeks, Timolol showed a loss in effectiveness. The application of Timolol instead of carbonic anhydrase inhibitors with acute angle-closure glaucoma and secondary glaucoma was successful. Timolol eye drops were tolerated very well. There were no local or systemic side effects.

Regional differences in the fine structure of the ciliary epithelium related to accommodation.

The ciliary bodies of five monkey eyes and one human eye were subdivided into five zones. The ciliary epithelium with its bordering stroma was investigated electron microscopically. The number of cell organelles of the nonpigmented (NPE) and pigmented (PE) epithelium (mitochondria, rough endoplasmic reticulum, Golgi complexes); intercellular junctions between NPE and NPE, PE and PE, and NPE and PE (desmosomes, puncta adhaerentia, gap junctions, tight junctions); and fenestrations of the capillary endothelium were quantitatively evaluated. All these types of cell organelles, fenestrations of the capillary endothelium, and gap junctions in the NPE were found in greater numbers at the crests of the ciliary processes than in the valleys between processes. On the other hand, the number of puncta adhaerentia is significantly higher in the valleys than at the crests. In the valleys, the internal limiting membrane performs an elaborate network of electron-dense strands in which many fine zonular fibers terminate. These fibers are believed to belong to the "tension fiber system." Their firm attachment to the ciliary epithelium and the great number of intercellular junctions known as mechanical structures lend further support to our concept that these structures function as a fulcrum in the process of accommodation.

[LP-X in newborns: increased incidence of positive tests without cholestasis (author's transl)].

The investigation of 194 newborns has shown that during the first weeks of life the abnormal lipoprotein-X (LP-X) was present in the serum of nearly 50% of the infants, with no clinical chemical evidence of cholestasis. The percentage of LP-X positive tests was even higher in the group of immature newborns (65%). There was no correlation between the bilirubin concentration and the detection of LP-X. The activities of leucine arylamidase (EC 3.4.1.1) and gamma-glutamyltransferase (EC 2.3.2.2) as well as the concentrations of total and free cholesterol did not differ in the LP-X positive and negative infants. Except in one case, LP-X was never detectable on the first day of life. The earliest date of appearance was the second day. In the serum of some infants, who were LP-X positive shortly after birth, the lipoprotein could still be found at the age of 2--3 months. The incidence of LP-X was not higher in newborns with blood group incompatibility than in newborns with unspecific hyperbilirubinaemia. After exchange transfusions LP-X disappeared in most cases, but it could later often be detected again. In some newborns, who were LP-X negative a few days after birth LP-X was first detected at the age of 2-3 months. The LP-X test is of no use for th diagnosis of cholestasis in newborn infants. The test is specific for cholestasis only after the first year of life. The increased incidence of positive LP-X tests in newborns is discussed as a consequence of immature liver function.

The rehabilitation/school matrix: a model for accommodating the noncompliant child with severe burns.

Some children with severe burns may have difficulty following therapeutic recommendations after discharge from a burn center. Noncompliance may result in complications that affect function, surgical management, community reintegration, and successful reentry into school. We present a case study in which a child with significant compliance issues was managed in a coordinated interdisciplinary model. This model extended from acute recovery through reintegration into the classroom. A behavior-modification program was implemented across different levels of care. Educational reentry was facilitated by including a transitional period in a special-needs classroom in a freestanding special-needs school. Requirements for using educational resources to which some children are legally entitled are reviewed. Rehabilitation services that interface with the educational system for children with burns may improve outcomes as these children reintegrate into the community.
