Late aseptic loosening of the acetabular component following total hip arthroplasty become increasing frequently after about 10 years and has become a more severe problem both in frequency and severity than femoral component loosening. The complexity of acetabular revision depends largely on the reconstruction required to restore normal anatomy due to acetabular bone loss. The clinical and radiologic results of acetabular revision using a porocoated acetabular component fixed to the pelvis with screws were studied in 36 patients (40 hips) who had moderate or severe acetabular loss. Acetabular revision in patients whose bone stock had already been destroyed provied more formidable problems at revision surgery. The mean Harris hip score was improved 46 to 84. Bone graft union was achieved by 7.4 months and incorporated by 16 months. The graft bone resorption was noted minor degree lateral to the cup. Of 40 cases, 2 cases required re-revision of acetabular cup for identifiable failure of fixation and one was showed probable loosening. The results of the present study suggest that revision of the acetabulum with use of a hemispherical cementless component stabilized with multiple screws and morselized bone grafts filling bone defects appears to be successful in restoring bone stock and providing a stable, pain-free reconstruction.

A synophthalmia, another form of cyclopia, in which the element of the two eyes are partially fused to form an apparently single eye in the middle of the forehead. The synophthalmia is a result of complex, neural plate misdevelopment syndrome involving the eye, brain, skull and face. It is well known that synophthalmia is due to heterogenous causes, most of which chromosomal imbalances. We experienced a case of synophthalmia associated with proboscis, alobar holoprosencephaly and chromosomal anomaly 46, XX, -15,t (15 q, 21 q). Diagnosis was confirmed by brain MRI and autopsy, The patient died about 20 hours of age and autopsy was done. A brief review of the literatures was also presented.

The influence of vitamin A acetate on the induction of bladder carcinogenesis by N-butyl-N-(4- hydroxybutyl) nitrosamine(BBN) was studied in male Wistar rats. Animals were divided into 4 groups : Group I and II received BBN and/or vitamin A acetate for 12 and 20 weeks. respectively. Group I and II were further divided into 3 subgroups : Subgroup a received BBN only, subgroup b BBN and vitamin A acetate in 100 IU per gram diet and subgroup c BBN and vitamin A acetate in 200 IU per gram diet, respectively. Group E received only vitamin A acetate and Group IV only basal diet. Animals were killed at 20 weeks after first carcinogen exposure and bladder was examined by both light and electron microscopy. At the two dose levels. vitamin A acetate significantly reduced the incidence and extent of carcinoma in Group I, as well as in Group X Vitamin A acetate of lower and higher dosage were nearly same in the inhibitory effect of development of carcinoma. Vitamin A acetate did not reduce the incidence of papilloma, but reduced the extent of papilloma in group I significantly. Vitamin A acetate also reduced the incidence of high grade neoplasm and deeply invasive cancer. Hypervitaminosis A did not develop at both lower and higher dosage of vitamin A acetate. Cancer cells in animals which received both vitamin A acetate and BShl often showed cytolysis, pyknosis and disruption of cellular membrane. The present findings indicate that vitamin A acetate inhibits or delays the development of bladder carcinoma without significant toxicity.
