The authors performed experimental study to produce proliferative vitreoretinopathy by intravitreal injection of homologous fibroblasts in pigmented rabbits. Twenty four eyes of 12 rabbits were divided into control and experimental groups. In experimental group, the eyes were pretreated with expanding gas, perfluoropropane for the vitrectomy. In control group, no such procedure was preceded. In both groups, 5.0×10⁴, 1.0×10⁵ and 1.5×10⁵ cells of homologous fibroblasts were injected into the vitreous cavity. All the eyes were observed regularly with indirect ophthalmoscope followed by fundus photography. Those eyes were enucleated in 1, 2, 4 weeks for the light and electron microscopic studies. The development and severity of the proliferative vitreoretinopathy were correlated with the numbers of the injected fibroblast. This was more pronounced in the experimental group.

The chronic osteomyeltis of the adult long bones has different problems from the acute osteomyelitis and osteomyelitis of the children. The ischemic scar tissues and infected bones of the chronic csteomyelitis in the adult are resistant to the antibiotic therapy and their healing mechanisms are delayed. The chronic osteomyelitis has no single effective method of treatment since every case reveals different conditions and the treatment should be individualized case by case. 87 cases of chronic osteomyelitis of the adult long bones were studied in the department of orthcpaedic surgery, Fatima Hospital for 7 years during the years between 1973 to 1979. The cases were 65 male and 22 female having ages 35 years in average and the duration of the osteomyelitis was 14 years and 4 months in average ranging from 3 months to 50 years. The cau ative organisms were mostly staphylococcus but Gram (−) bacilli were found in 28% and the adjacent joint problems were found in 38% The cases were analysed in 5 different groups according to x-ray findings as follows; I. Group with sequestrum: 23 cases having sequestra with varying degree of bone sclerosis and destruction. Most cases had draining sinus but the soft tissue involvement was not severe. II. Sclerotic group: 32 cases having significant bone sclerosis with minimal destructicn if any. The soft tissue involvement and scarring were severe but involvement of the bone marrow was not significant. The duration of osteomyelitis was longest having recurrent episodes of the painful swelling in most cases. III. Destructive group: 17 cases with significant bone destruction with varying degree cf sclerosis. The involvement of the bone marrow was significant and soft tissue involvement was not marked The duration of osteomyelitis was short mostly. IV. Group with skin problem: 9 cases having scar problems overlying tibia. V. Group with complication: There were 2 pathologic fractures of the femurs, 3 quamous cell carcinomas on the lower legs and a severe deformity of a leg. Treatment was mostly surgical including 4 amputations. The surgical method was focused on saucerization of the bone and extensive excision of the infected soft tissues and the scar tissues. 23 cases having small or no dead cavity after mobilization and suture of the adjacent healthy soft tissue closed primarily. Otherwise the cavity was packed open for econdary healing in other 23 cases including several cases having big cavity which was unable to close the skin. The cases having big cavity were prepared for continueus irrigation in 14 caes which were able to closed skin. The transposition of muscles to fill the dead cavity was performed in 4 cases that had big cavity and was unable to close skin. The results were healing in 10 weeks in 54% and after 10 weeks in 38% and 8% failed to heal with the first trials. The recurrence of the ostecmyelitis was found in 9 cases among the 42 cases followed for I year and 3 months in average mostly in group II and in cases of primary closure and open packing.

Four families having identical sacral agenesis were reported in the literatures and an another family is added here. This family has an eleven year old boy and a seven year old girl who have identical complete sacral agenesis without spincter disturbance but with some anomalies in the other spines, rib and progressive club feet. These cases are followed for six years and the foot deformity was corrected by surgery.

Low back pain and radiating pain in the leg are the main symptoms of the spondylolisthesis and various surgical treatments are recommended after having enough conservative treatments. The spinal fusion in situ either posterior, posterolateral or anterior route is the usual method for symtomatic spondylolisthesis or to prevent progression of slipping but the neurogenic symptoms in the legs are not well solved, so the decompression procedures are necessary. The authors reviewed 26 cases of isthmic spondylolisthesis having low back pain and sciatica which are operated during the 10 years since 1973 at Fatima Hospital and the followings are obtained. 1. There were 15 males and 11 females with ages from 18 years to 63 years having average 40.1 years. 2. The displaced vertebrae were 5th lumbar in 18 and 4th lumbar in 8 cases and the degree of displacement was Grade I in 14, Grade II in 10, Grade III in 1 and no slipping in 1 case. 3. The types of surgery were decompression and H-graft in 22, simple posterior fusion in 3 and Gll's procedure in 1 case. 4. The laminas were considerably loose in all cases and there were small fibrous mass at the pars area in half of the cases. .5. The spine became very stable immediately after H-grafting and the intervertebral foramen became widened freeing nerve root. 6. Bony union obtained in 88% and satisfactory result in 85% at the follow-up from 6 months to 7 years and 2 months with average 1 year and 7 months. 7. The decompression is necessary for the radiating pain in the leg and H-grafting is satisfactory and simple procedure after decompression laminectomy.

Primary subacute pyogenic osteomyelitis is defined as a bone infection of insidious onset lasting for more than several weeks without any acute systemic toxic reactions and is known to have the problem of diagnosis because there is no inflammatory symptoms or signs and X-ray findings are similar to various bone tumors. Authors reviewed 29 cases of primary subacute pyogenic osteomyelitis of long bones admitted at Fatima hospital during the years between 1976 and 1984. The osteomyelitis of infants and the osteomyelitis modified by antibiotics were excluded. The diagnosis of the cases was confirmed by bacteriological examination and/or tissue examination. The results were as follows. 1. The cases were 18 males and 11 females and 19 adults and 10 children. Male predominence was noted in children. 2. The involved bones were 11 tibias, 10 femurs and all other long bones. The involved sites were 18 metaphysis and 11 shafts. 3. All of the cases has insidious onset of local pain without any acute systemic symptoms and most of the cases has local tenderness but local deep swelling noted in about half of the cases. 4. There were many cases with elevated ESR and a few cases of slight leukocytosis. 5. The confirmed infecting organism was all staphylococcus in 16 cases of the cultures from the 25 lesions. 6. The X-ray findings were Brodies abscess in 10, illdefined cavity in 3, diffuse bones absorption in 5, diaphyseal lesion of adult with localized cortical sclerosis in 5 and with localized medullary abscess in 3 and diaphyseal lesion of children with localized medullary abscess and periosteal reaction in 3 cases. 7. All of the cases cured rapidly with rare recurrence after treatment by simple local excision in 4 and curettage in 22 cases combined with antibiotic therapy and local immobilization.

Natural look of breast after augmentation mammoplasty is a common end of both plastic surgeons and patients. Palpability and visible rippling after augmentation mammaplasty is not a simple complication to correct in relatively thin patients especially when there is not much soft tissues remain to cover the implant for smooth contour. And asymmetry of the breast in accordance with the skeletal deformity, such as pectus excavatum, can not be easily reformed with insertion of silicone implant alone. In the present study, volume enhancement was accomplished by silicone implant augmentation and contour management was improved with the help of fat graft technique. We named the technique "Hybrid Augmentation Mammoplasty". From May 2011 to Feb. 2012, the hybrid augmentation mammoplasty procedure were performed on 9 patients who expected to have palpable implants, visible rippling or asymmetry due to their soft tissue and skeletal condition. Breast augmentation with silicone implant was done in regular pattern followed by grafting fat tissues utilizing Harvest-jet device into the pre-pectoral, sub-glandular and subcutaneous layer. During the follow-up period, any patient complained palpability of the implant and all of them were satisfied with the contour of their breast. Hereby we suggest that the hybrid augmentation mammoplasty can be an ideal, effective and useful option in management of thin skinned patients or patients with chest wall deformities.
