A comparison of stapled vs handsewn anastomosis in anterior resection for carcinoma rectum.

The merits of stapled versus hand sewn anastomosis were evaluated in a prospective randomized study of 60 patients undergoing resection for rectal cancer. The analysed factors included the time required for construction of anastomosis, post operative complications, local recurrence, disease free state and survival. Hand sewn anastomosis was performed in two layers with 3/0 silk in 30 cases and the stapled anastomosis with EEA staplers in 30 cases. The anastomosis time averaged 24 minutes in the suture group and 16 minutes in the stapling group. Five post-operative complications occurred in each group. Six patients of the hand sewn group developed local recurrence as a first sign of treatment failure compared to four patients in the stapled group. The average time of study was 41 months. No significant difference was found in the overall survival pattern of the two groups.

Experience in elective hepatic resection.

A study was conducted on 35 elective hepatic resections performed by one surgical team over a period of 5 years with 14% postoperative mortality. The indications for hepatic resection were primary hepatocellular carcinoma in 20 cases (57%) and metastatic tumours from colorectal cancer in 12 cases (34%). Underlying cirrhosis of liver was found co-existent in 35% of patients of hepatocellular carcinoma. The 3-year actuarial survival rate after resection for HCC and metastatic tumour was 30% and 42% respectively.

Bacteriology of ophthalmic infections with special reference to anaerobes.

A total of 138 eye specimens were processed for aerobic and anaerobic cultures. Clinical data were obtained from 50 patients with unilateral ophthalmic infection. Cultures from the uninfected eye of 38 of these 50 patients were also processed for comparison. In addition, 50 cultures were obtained from one or both eyes of 30 healthy controls who had no eye infection. Anaerobes and aerobes were isolated from infected eyes of 6 (12%) and 37 (74%) patients respectively. No growth was observed in infected eye of 8 (16%) patients. A mixture of aerobes and anaerobes were recovered only in 2 cases. Of the total 47 aerobic isolates from infected eye specimens, Staphylococcus aureus (11), coagulase negative staphylococci (12) and Streptococcus pneumoniae (9) were predominant isolates. Six anaerobes isolates included Gram positive nonsporing anaerobic bacilli (4 including Propionibacterium acne) as predominant isolates. Clostridium perfringens was isolated from a case of post operative endoophthalmitis. From the uninfected eye of same patients though the number and types of aerobic bacteria were similar, none grew any anaerobes. Aerobic and anaerobic bacteria were isolated in 70 and 6 per cent of eye swabs respectively from the healthy controls.

Gastric cancer: a critical analysis of surgical treatment and long term survival.

Results of consecutive study of 120 cases of carcinoma stomach treated by one surgical team over a period of 10 years (1980-89) are presented. Maximum cases were in the sixth and seventh decades with male to female sex ratio of 2.5:1. The lesion in most cases were in the gastric antrum. Distal tumours were more of poorly differentiated histology compared to proximal tumours. Eighty-three out of 120 (69%) patients underwent surgical resection. In 50 patients it was in the form of a subtotal and distal gastrectomy. Only 5 patients underwent a total gastrectomy. In 70 cases the resection which involved en bloc removal of involved part of stomach including adequate proximal and distal free margins, omenta and perigastric lymph nodes and considered absolutely curative in 8 cases being no disease. The overall 5-year-survival figure was 18%. However, taking only the resected cases into account, the 5-year survival rate was 27%. The low survival figure can be attributed to a very small number of early cases encountered.

Prosthetic mitral valve mucormycosis caused by Mucor species.

We report, to the best of our knowledge the first case of prosthetic mitral valve mucormycosis caused by Mucor species in an 18-year-old female after mitral valve replacement. She was successfully treated with surgery and antifungal treatment. Mucormycosis was documented by direct demonstration, isolation and histopathological findings of the fungus from embolus and prosthetic mitral valve thrombus.

Prevalence of Mycoplasma pneumoniae and Chlamydia pneumoniae in children with community acquired pneumonia.

A prospective one year study was performed on 62 children admitted at the All India Institute of Medical Sciences with community acquired pneumonia (CAP) for the prevalence of Mycoplasma pneumoniae and Chlamydia pneumoniae. Diagnosis of infection with M. pneumoniae was based on serological tests viz microparticle agglutination test for detection of IgM antibodies and indirect immunofluorescence test for antigen detection from throat swabs (sensitivity 85.7%, specificity 93.3%). The indirect solid-phase enzyme immunoassay for detection of IgG antibodies was used to determine the prevalence of C. pneumoniae (sensitivity 88.8%, specificity 75.8%). Seventeen patients (27.4%) were found to have serological evidence of M. pneumoniae infection whereas only 4 (6.4%) patients were seropositive for C. pneumoniae. Results of this study indicate that M. Pneumoniae plays a significant role in CAP in infants and young children. Thus specialized laboratory testing for these agents should be more widely used thereby affecting empiric antibiotic regimens.

Anaerobic septicaemia by Fusobacterium necrophorum: Lemierre's syndrome.

Lemierre's syndrome is characterized by acute pharyngotonsillitis with secondary thrombophlebitis of the internal jugular vein which is complicated by multiple metastatic foci of infections. This syndrome is caused by Fusobacterium necrophorum in healthy young persons and is extremely rare in occurrence. A pre-school child with Lemierre's syndrome is reported. The diagnostic and therapeutic aspects are emphasized in order to sensitize physicians to this uncommon condition.
