Autoimmune thrombocytopenia (AITP) is caused by autoantibodies to platelet glycoprotein antigens. Intravenous immunoglobulin (i.v.IgG) and Rh immunoglobulin infusions have found great significance in the treatment of AITP patients not responding to corticosteroids and other modes of therapy. In our study, it was observed that immunoglobulins (i.v.IgG & Rh), and their Fab fragments inhibited the binding of antiplatelet autoantibodies to normal platelets, from 15.8 to 90.7% and 25.6 to 90.08% respectively; whereas, their Fc portion did not show any inhibition. The presence of specific anti-idiotypic antibodies to antiplatelet autoantibodies was established by using monoclonal antibodies to Glycoprotein IIb/IIa and Glycoprotein Ib/IX, as the specific idiotype source. The i.v.IgG and Rh immunoglobulin products reacted with the monoclonal antibodies, only through their Fab and not through the Fc portions, thereby confirming its specific anti-idiotype activity.

100 patients with ASA risk I & II and undergoing perianal surgery were studied for anaesthetic effects and postoperative analgesia following either intrathecal pethidine or lignocaine. Saddle block was performed either with intrathecal pethidine 5% (50 mg/ml) 0.5 mg/kg or 1 ml of 5% lignocaine. Sensory and motor block postoperative analgesia, need for additional analgesia were studied. The onset of sensory and motor blockade with lignocaine was faster than pethidine. However the sensory and motor blockade lasted longer with pethidine. The duration of postoperative analgesia was 15.39 +/- 5.14 hours as against duration of postoperative analgesia with lignocaine which was 1.3 +/- 0.53 hours. Only 10% of patients in the pethidine group required intramuscular analgesic supplementation whereas 30% of patients in the lignocaine group required intramuscular analgesic supplementation.

Forty cases of Austin Moore Replacement done for transcervical fractures of the femur in patients were reviewed after a period of 12 to 48 months postoperatively (mean 26 mth). 30 cases (75%) had mild to severe pain of non-infective origin, starting as early as 6 months postoperatively. This was irrespective of the make, size or position (varus/valgus) of the prosthesis. Though the Aufranc and Sweet clinical scoring was satisfactory in 65% cases, radiological evidence of complications like sinking, protrusion, etc. were seen in majority of the cases. Calcar resorption was seen in 34 cases (85%) as early as 4 months postoperatively. Results of THR and bipolar replacement done for transcervical fractures in recent literature show 85% pain-free cases at 5 years. We feel that Austin Moore Replacement should be reserved for patients more than 65 years of age and those who are less active or debilitated because of other factors, because of increased acetabular wear with time in the younger individual. This is corroborated by unsatisfactory results in patients less than 65 years of age (p < 0.05).

Although serum thyroglobulin (STg) is a useful tumour marker to detect the recurrence of tumour in well differentiated thyroid carcinoma, it has as yet not been reported to be of value in predicting the behaviour of thyroid cancer. In the present study of 20 patients, the measurement of preoperative Stg/thyroid mass has been utilised to find out Tg synthesizing capacity of the tumour. This ratio was significantly higher in the patients with follicular variety than in papillary thyroid carcinoma. It was significantly higher in the metastasis group than in the group of patients without metastasis. The patients with functioning metastasis had a higher than average value of this 'ratio' than those with non functioning metastasis, though the difference was not statistically significant. Despite the limitation of a small number of patients included in this study, it is possible to highlight the possible utility of preoperative Stg estimation as a tumour marker in categorization of the patients of carcinoma of the thyroid gland.

Although Fallopian tubes are frequently involved in benign gynaecological conditions, primary malignant involvement is rare, and because of its rarity, lack of diagnostic accuracy, nonpresenting symptoms and physical findings, primary fallopian tube carcinoma is seldom diagnosed before laparotomy. We are reporting one such rare case.

An unusual astrocytoma occurring in different anatomical compartments of the brain is reported. The child was operated upon for a cerebellar astrocytoma when he was eight-and-half years old. Seven years later, he was operated for a cerebral astrocytoma. The growth of the similar tumours at these two sites is analysed and literature on the subject is reviewed. The concept of multicentricity is emphasized.

Desmoplastic fibroma is a rare primary tumour of bone. When it does occur, the sites of predilection are the long bones. The following is a case report of desmoplastic fibroma involving both bones of forearm in a 12 year old boy with a review of literature.
