BALDNESS 1 (technically alopecia, from ItXcInrrl, a See also:

fox, foxes often having bald patches on their coats)  , the result of loss of See also:hair, particularly on the human See also:scalp . So far as remediable alopecia is concerned, two forms may be distinguished: one the premature baldness so commonly seen in See also:young men, due to alopecia seborrhoica, the other alopecia areata, now regarded as an epidemic disease . Alopecia seborrhoica is that premature baldness so constantly seen, in which the See also:condition steadily advances from the forehead backwards, until only a fringe of hair is See also:left on the See also:head . It is always due to the underlying disease See also:seborrhoea, and though it progresses steadily if neglected, is yet very amenable to treatment . The two drugs of greatest value in this trouble are See also:sulphur and salicylic See also:acid, some eighteen grains of each added to an See also:ounce of See also:vaseline making a See also:good application . This should be rubbed well into the scalp daily for a prolonged See also:period . Where the greasiness is objected to, the following salicylic lotion may be substituted, 1 The See also:adjective " bald " M . E . " balled " is usually explained as literally " See also:round and smooth like a See also:ball," but it may be connected with a See also:stem bal, See also:white or shining . The See also:Greek oaXaKpos certainly suggests some such derivation.though the vaseline application has probably the greater value: Ac. salicyl . 3i—iv; 01. ricini 3 ii—vi; 01. See also:ros. geran . 111 x; Spt. vini ad 3 vi .

The head must be frequently cleansed, and in very mild cases a daily washing with See also:

soap spirit will at times effect a cure unaided . Alopecia areata is characterized by the development of round patches more or less completely denuded of hair . It is most commonly observed on the scalp, though it may occur on any See also:part of the See also:body where hair is naturally See also:present . The patches are rounded, smooth and somewhat depressed owing to the loss of a large proportion of the follicles . At the margin of the patches See also:short broken hairs are usually to be seen . Clinical See also:evidence is steadily accumulating to show that this disease may be transmitted . Organisms are invariably present, in some cases few in number, but in others very abundant and forming a continuous sheath round the hair . They were first described by Dr See also:George Thin, who gave them the name of Bacterium decalvens . The disease must be distinguished from See also:ringworm--especially the bald variety; but though this is at times somewhat difficult clinically, the use of the See also:microscope leaves no See also:room for doubt . It must be remembered that for patients under See also:forty years of See also:age; See also:time alone will generally bring about the desired end, though treatment undoubtedly hastens recovery . After forty every See also:year added to the patient's age makes the See also:prognosis less good . The See also:general See also:hygiene and mode of See also:life of the sufferer must be very carefully attended to, and any weakness suitably treated .

The following lotion should be applied daily to the affected parts, at first cautiously, later more vigorously, and in stronger See also:

solution: Acidi lactici 3 i—3 i; 01. ricini 3 ii; Spt. vini ad 3 iv . The loss of hair following acute fevers must be treated by keeping the hair short, applying stimulating lotions to the scalp, and attending to the general hygiene of the patient . •BALDOVINETTI, ALESSIO (1427-1499), Florentine painter, was See also:born on the 14th of See also:October 1427, and died on the 29th of See also:August 1499 . He was a follower of the See also:group of scientific realists and naturalists in See also:art which included See also:Andrea del See also:Castagno, See also:Paolo Uccello and Domenico Veneziano, the See also:influence of the last-named See also:master being particularly See also:manifest in his See also:work . Tradition, probable in itself though not attested by contemporary records, says that he assisted in the decorations of the See also:chapel of S . Egidio in See also:Santa Maria Nuova, carried out during the years 1441–1451 by Domenico Veneziano and in See also:conjunction with Andrea del Castagno . That he was commissioned to See also:complete the See also:series at a later date (1460) is certain . In 1462 Alessio was employed to paint the See also:great See also:fresco of the See also:Annunciation in the See also:cloister of the Annunziata, which still exists in ruined condition . The remains as we see them give evidence of the artist's See also:power both of imitating natural detail with See also:minute fidelity and of spacing his figures in a landscape with a large sense of See also:air and distance; and they amply verify two See also:separate statements of See also:Vasari concerning him: that " he delighted in See also:drawing landscapes from nature exactly as they are, whence we see in his paintings See also:rivers; See also:bridges, rocks, See also:plants, fruits, roads, See also:fields, cities, exercise-grounds, and an infinity of other such things," and that he was an inveterate experimentalist in technical matters . His favourite method in See also:wall-See also:painting was to See also:lay in his compositions in fresco and finish them a secco with a mixture of yolk of See also:egg and liquid See also:varnish . This, says Vasari, was with the view of protecting the painting from See also:damp; but in course of time the parts executed with this vehicle scaled away, so that the great See also:secret he hoped to have discovered turned out a failure . In 1463 he furnished a See also:cartoon of the Nativity, which was executed in tarsia by Giuliano de Maiano in the See also:sacristy of the See also:cathedral and still exists .

From 1466 date the See also:

groups of four Evangelists and four Fathers of the See also:Church in fresco, together with the Annunciation on an oblong See also:panel, which still decorate the Portuguese chapel in the church of S . Miniato, and are given in See also:error by Vasari to Pietro See also:Pollaiuolo . A fresco of the risen See also:Christ between angels inside a See also:Holy See also:Sepulchre in the chapel of the Rucellai See also:family, also still existing, belongs to 1467 . In 1471 Alessio undertook important See also:works for the church of Sta Trinita on the See also:commission of Bongianni Gianfigliazzi . First, to paint an See also:altar-piece of the Virgin and See also:Child with six See also:saints; this was finished in 1472 and is now in the See also:Academy at See also:Florence: next, a series of frescoes from the Old Testament which was to be completed according to See also:contract within five years, but actually remained on See also:hand for fully sixteen . In 1497 the finished series, which contained many portraits of leading Florentine citizens, was valued at a thousand See also:gold florins by a See also:committee consisting of Cosimo See also:Rosselli, Benozzo See also:Gozzoli, See also:Perugino and Filippino See also:Lippi; only some defaced fragments of it now remain . Meanwhile Alessio had been much occupied with other technical pursuits and researches apart from painting . He was regarded by his contemporaries as the one craftsman who had rediscovered and fully understood the See also:long disused art of See also:mosaic, and was employed accordingly between 1481 and 1483 to repair the mosaics over the See also:door of the church of S . Miniato, as well as several of those both within and without the See also:baptistery of the cathedral . These are the recorded and datable works of the master; others attributed to him on good and sufficient See also:internal evidences are as follows: —A small panel in the Florence Academy, with the three subjects of the See also:Baptism, the See also:Marriage of See also:Cana and the Transfiguration; this was long attributed to Fra See also:Angelico, but is to all See also:appearance See also:early work of Baldovinetti: an Annunciation in the Uffizi, formerly in the church of S . Giorgio; unmistakably by the master's hand though given by Vasari to Peselino: several Madonnas of peculiarly See also:fine and characteristic quality; one in the collection of Madame See also:Andre at See also:Paris acquired See also:direct from the descendants of the painter, a second, formerly in the Duchatel collection and now in the Louvre, a third in the See also:possession of Mr Berenson at Florence . All these are executed with the determined See also:patience and precision characteristic of Baldovinetti; two, those at the Louvre and in the Andre collection, are distinguished by beautiful landscape backgrounds; and all, but especially the example in the Louvre, add a See also:peculiar and delicate See also:charm to the quality of See also:grave See also:majesty which Alessio's works See also:share with those of See also:Piero della Francesca and others of Domenico Veneziano's following .

They probably belong to the years 1460-1465 . In the later of his preserved works, while there is no See also:

abatement of precise and laborious finish, *e find beginning to prevail a certain harshness and commonness of type, and a lack of care for beauty in See also:composition, the technical and scientific searcher seeming more and more to predominate over the artist .
