    Anal fistula in infants is considered to be not due to diaper dermatitis but it is developed in the process: hyperfunction of sebaceous glands induced by either excessive secretion of sex hormones (maternal hormones and hormones in the baby) or disorders related to hormones-acne vulgaris-fistula forma-tion.
    Because the incidence of infantile anal fistula is very high in patients below the age of one month, the author recommends to put this fistula in the category of diseases of newborn babies, and to call it “fistula ani neonatorum”.
    It is presumed that the fistula-in-ano which is usually observed in adult is also due to the abnormal development of pilo-sebaceous system or of free sebaceous glands (Fordyce's disease) of the anus. That is, the anal fistula in adults is pathogenically the same as that in infants. In addition, it is neces-sary to reconsider the theory in which cryptoglands infection is regarded as the cause of anal fistula.

    In retinal detachment, the subretinal fluid is absorbed by the choroid when all retinal holes are closed by surgery. It usually takes 16 to 48 hours, but in a few cases it prolongs weeks to months depending on the function of the choroid. There has been few reports on cases whose subretinal fluid persisted for over four months and the mechanism of such a long delay in absorption has never been elucidated.
    The hospital charts of 130 surgically treated retinal detachment patients at the Keio University Hospital during the period of August, 1973 to July, 1975 were looked through to pick out cases whose postoperative courses were complicated by the prolonged presence of subretinal fluid for over 4 months in spite of adequate closure of all retinal holes. The out-patient clinic charts of these patients were carefully analysed at the same time to categorize these patients and to find out the mechanism of delay in absorption of subretinal fluid.
    The patients were usually young. The retinal detachments were usually shallow with small round holes and involved one or two quadrants. Most of them received a relatively minor procedure without drainage of the subretinal fluid. All had good visual acuity both pre- and postoperatively. Slitlamp examination of the detached retina in these cases indicated that the retina was too short to settle down to the choroidal surface and this seemed to be the mechanism of delay in absorption.
    Since these cases eventually reattached and recovered, it was recom-mended to follow these cases conservatively. The importance of recognizing these cases were emphasized and “Tented retina syndrome” was suggested to indicate this state of retina after retinal detachment surgery.

    The studies on drug-induced persistent dyskinesia in Japan began only in the late nineteen-sixties, while the first historical description of the symptom by French authors was published in 1959. Then, at first, the literatures re-ported by Japanese workers were briefly reviewed and the prevalences, char-acteristics of the patients and correlations between the manifestation of the symptoms and characteristics of psychotropic drugs were summarized.
    Secondly, two clinically important problems were discussed from the findings of 19 dyskinetic patients in Minakawa Mental Hospital. The first problem was concerned with the reversibility of persistent dyskinesia and the second with the relationship between persistent dyskinesia and other types of extrapyramidal reactions.
    In conclusion, it was stressed that the earlier diagnosis and earlier re-moval of the drug were important for the prophylaxis of irreversible persistent dyskinesia and that close relationship of persistent dyskinesia with the other types of extrapyramidal reaction (acute dyskinesia, akathisia and parkin-sonism) should be taken into consideration for the prediction of the symptom.

    The mechanical movement of the knee joint is analysed by the tibio-femoral, tibio-menisco-femoral and patello-femoral contact using the silicon rubber embossment.
    The movement of the knee joint consists of three major phases from the functional point of view.
    (1) Hinge Phase The range of motion over 60 degree of flexion where the the femoral condyle slips on the tibial table.
    (2) Rolling Phase The range of motion from 15 to 60 degree of flexion where the femoral condyle rolls over the tibial table with some different slipping factor in both condyles.
    (3) Screw Home Phase The range of motion from full extension to 15 degree of flexion where the lateral condyle glides on the tibial table which is a pivotal turn while the medial condyle rolls over the tibial table.

    Out of one hundred and sixty-two femoral neck fractures, twelve reopera-tive cases were analysed and discussed relating to the causes of the reopera-tion. The twelve patients were consisted of eleven females and one male. The age distribution ranged from 60 years to 72 years, average age being 65 years. The internal fixations were performed by Smith-Petersen nail, multiple pinning with K-wires, hip plate and A-O screw.
    Most important factor required reoperation was a poor reduction of the fracture. Other factors leading to reoperation were early weight bearing and inadequate selection of the fixation materials.
