Carcinoma of stomach in a patient with familial tylosis.

The association of tylosis with esophageal cancer has been extensively reported but association with gastric cancer is rare. We report a 55-year-old man with familial tylosis and carcinoma of the stomach for which radical gastrectomy was done. Repeat endoscopy 3 years later is normal.

Hepatic resection for benign liver pathology--report of two cases.

Hepatic resection for benign pathology is rare. We report our experience in two patients with hepaticolithiasis. One patient underwent left hemihepatectomy with removal of segments II, III and IV for localized Caroli's disease with multiple intrahepatic calculi. The second patient underwent resection of segment II and III with Roux-en-Y hepaticojejunostomy for right and left intrahepatic calculi with an abscess in the left lobe of the liver and a choledochal cyst.

Cerebrospinal fluid N-acetyl neuraminic acid estimation for early diagnosis and differentiation of bacterial meningitis.

Cerebrospinal fluid (CSF) analysis for free, bound and total N-Acetyl Neuraminic Acid (NANA) as well as serum NANA was done in 68 patients of bacterial meningitis, of which 37 cases were of pyrogenic meningitis and 31 of tuberculous meningitis. Ten patients were included in the control group. The free NANA levels were increased in only pyogenic meningitis, independent of protein levels but the bound form increased with the increase in CSF proteins. The increase of free NANA in CSF of pyogenic meningitis patients was not related to the cell count or sugar content in CSF or to the duration or severity of illness. This finding can be of great help in differentiating cases of pyogenic meningitis, particularly partially treated patients, who may have ambiguous pictures of CSF analysis, from the cases of tuberculous meningitis.
