Orbital floor repair with titanium mesh screen.

BACKGROUND AND OBJECTIVES: Surgical repair of the acutely fractured orbit strives to restore appearance, preserve ocular and orbital function, and avoid enophthalmos or hypoglobus. Repair is achieved with autologous bone graft, synthetic substitutes, or both. The purpose of this article is to present an alternative procedure--use of implants, cut from a titanium mesh screen, without bone graft. METHOD AND MATERIALS: A total of 51 orbital floor fractures in 43 patients were repaired with titanium mesh screen implants. In three patients with bilateral orbital floor fractures repaired with titanium mesh, intraoperative symmetry was improved with bone graft added to the mesh on one side. RESULTS AND/OR CONCLUSIONS: Follow-up was available for 42 orbits in 35 patients and averaged 9 months. The transconjunctival approach with lateral canthotomy yielded better results than the subciliary approach, which often caused transient scleral show or ectropion. One patient underwent surgery for ectropion following a subciliary approach, and one patient developed a 4-mm enophthalmos. Routine bone grafting is unnecessary, even in large floor defects. Titanium mesh implants are a simple and reliable option for orbital floor repair.

Massive mature solid teratoma of the ovary with gliomatosis peritonei.

Glial implants on peritoneum and omentum may occur with mature solid teratoma of the ovary (gliomatosis peritonei). The case of a 17-year-old girl is presented, who had a massive solid ovarian teratoma with glial implants on visceral peritoneum and omentum. The massive size of the tumour posed difficulty in diagnosis. CT demonstrated a large teratoma. At laparotomy, the seedlings were initially thought to be evidence of malignancy and hysterectomy was offered which was refused by the parents. Oophorectomy was performed and the benign nature of the tumour and implants was seen on histopathology. It is important to recognize the benign nature of glial seedlings in such cases to avoid unnecessary extensive surgery.

Actinomycotic cholecystitis.

Actinomycotic cholecystitis is rare. We report a 65-year-old woman who was admitted with repeated attacks of pain in the abdomen and vomiting. Clinical and laboratory findings suggested the diagnosis of cholecystitis with cholelithiasis. At cholecystectomy the gall bladder was inflamed with a small perforation, and contained many calculi. Gram's staining of the gall bladder wall revealed Gram-positive actinomycotic colonies.

Histopathological changes in aluminium phosphide poisoning.

A total of thirty cases of aluminium phosphide poisoning were studied for gross and microscopic changes in various organs of the body ie, lungs, liver, kidneys, heart, brain, stomach and adrenals. The histopathological changes revealed varying degrees of congestion, oedema and leucocytic infiltration, changes suggestive of cellular hypoxia. The most dramatic effects were produced in lungs, kidneys and adrenals.

Magnesium status and parenteral magnesium sulphate therapy in acute aluminum phosphide intoxication.

The results of an open randomized study on magnesium status and parenteral magnesium sulphate therapy in acute aluminium phosphide intoxication are presented. The study was conducted on 105 patients divided into two group (I & II). Patients of Group I did not receive parenteral magnesium and acted as blank. Magnesium levels were monitored every 6 h for 24 h. Patients of group II received magnesium sulphate therapy. It was administered as 1.0 g (8.1 mEq or 4.05 mmol) magnesium sulphate dissolved in 100 ml of 5 per cent dextrose intravenously as a bolus dose followed by 1.0 g every hour for three successive hours, then 1.0 g every 6 h as a maintenance dose for the next 24 h as intravenous infusion in 5 per cent dextrose. The total dose of magnesium sulphate infused was 30.0 mmol over a period of 24 h (initial dose), then 16.0 mmol (4.0 g) daily till final outcome or a maximum of five days. All the vital parameters were monitored. All the patients were followed till final outcome. The resuscitation methods used were the same in both groups. At the end of the study, mortality rates were calculated in both groups. Hypomagnesaemia was observed as the constant finding in patients of Group I. It was transient and reversed itself without MgSO4. The mortality rate was 52 per cent. On the other hand, magnesium levels rose immediately after parenteral MgSO4 administration in patients of group II and they remained persistently above normal during the observed period.(ABSTRACT TRUNCATED AT 250 WORDS)

Magnesium levels in acute cardiotoxicity due to aluminium phosphide poisoning.

Significant hypomagnesemia and hypomagnocytia were observed in patients of aluminium phosphide (AIP) poisoning having evidence of acute cardiotoxicity while magnesium levels were normal in patients of AIP poisoning without shock or cardiotoxicity as well as in controls. There was a direct relationship between electrocardiographic findings and low magnesium levels. The mortality was also related directly to hypomagnesemia. The dose of pesticide also influenced the mortality adversely. Autopsied heart showed changes of toxic myocarditis on histopathology.

Incidence & outcome of aluminium phosphide poisoning in a hospital study.

A total of 418 patients with aluminium phosphide poisoning admitted during January 1981 to December 1987, were studied and analysed for various clinical parameters. A steady increase in the number of patients was seen during the last 7 yr. Maximum number belonged to the younger generation and nature of poisoning was suicidal in most of these patients. Dose of poison consumed varied, but most patients consumed two tablets (6 g). A wide range of symptoms and signs was seen, the commonest being gastrointestinal manifestations and shock. Cardiac arrhythmias and conduction disturbances were seen in 38.2 per cent patients. The overall mortality was 77.2 per cent. Indices of a bad prognosis included poor response to dopamine infusion and continuous increase in its dosage, chest infections, adult respiratory distress syndrome and disseminated intravascular coagulation. The complications noticed were pericarditis, congestive cardiac failure, acute gastrointestinal haemorrhage and acute respiratory arrest. Histopathology of various organs showed changes suggestive of cellular hypoxia but the mechanism of ECG changes and of the complications could not be elucidated.

Fine needle aspiration cytology in diagnosis of tuberculous lymphadenitis.

Fine needle aspiration cytology and culture were done on 200 patients with clinical diagnosis of tuberculous lymphadenitis. Cytological changes consistent with tuberculosis were seen in 124 and 100 of these showed growth of Mycobacterium tuberculosis. Atypical mycobacteria were not isolated from any of these patients. Of the 100 culture positives, 75 were found to be positive by auramine-rhodamine and Ziehl-Neelsen staining technique. However, with the latter method the diagnosis was missed on first examination of eight smears. With periodic acid-Schiff staining mycobacteria could be visualised in 71 smears.

Carcinoembryonic antigen and human chorionic gonadotrophin in breast carcinoma and prostatic specific acid phosphatase in prostate carcinoma.

Tumour markers viz carcinoembryonic antigen (CEA), human chorionic gonadotrophin (HCG) in 30 cases of carcinoma breast and prostatic specific acid phosphatase (PSAP) in 30 cases of carcinoma prostate were studied by peroxidase antiperoxidase technique in paraffin blocks of tissue. Twenty three (76.7%) and 20 (66.7%) cases were positive for CEA and HCG respectively. No correlation was observed between CEA and HCG status, and histological differentiation of the tumours. All the 29 cases (100%) of adenocarcinoma prostate were PSAP positive while a single case, negative for PSAP, was of transitional cell carcinoma.

Sex chromatin in female breast tumour.

The incidence of sex chromatin in tumour cell nuclei was estimated in twenty five cases each of carcinoma and fibroadenoma breast using haematoxylin and eosin, thionine, aceto-orcein and Papanicolaou's stains on imprint-smears. The sex chromatin incidence in fibroadenoma was found similar to that of normal breast tissue but the incidence markedly decreased in carcinoma breast. Undifferentiated tumours with histologic grade III, nuclear grade I, no lymphocytic infiltrate and involvement of overlying skin, nipple and areola were more often associated with low sex chromatin incidence. No relationship was observed between sex chromatin incidence and tumour size or axillary lymph node metastasis.
