Superficial collateral veins on abdominal CT: findings in cirrhosis and systemic venous obstruction

Inspection of the superficial veins of the abdominal wall has long been a routine part of the physical examination. To date, radiologists have given such veins rather scant attention, even though they are elegantly demonstrated by CT. We have performed a study of 21 patients with cirrhosis, 7 patients with caval obstruction and 28 normal control counterparts in order to determine whether superficial veins were more numerous in these two clinical conditions. The 7 patients with caval obstruction included 4 with superior and 3 with inferior vena cava obstructions. Electronic data from the CT examinations of these 28 cases and 28 controls were analysed on a viewing console. Superficial veins were significantly more numerous in patients with cirrhosis (mean maximum=5, p<0.01) and caval obstruction (mean maximum=9.1, p<0.01) than in the normal controls (mean maximum=2.1). The combination of too many superficial veins and a large superior mesenteric vein is a pointer towards cirrhosis. The presence of excessive superficial veins is yet another clue to the presence of underlying disease when analysing abdominal CT.

Prevalence of behaviour disorders in low birthweight infants

OBJECTIVE--To determine the prevalence of behaviour disorders in low birthweight infants. DESIGN--Children of birth weight < or = 2000 g born to mothers resident in Merseyside in 1980-1 assessed using the Rutter parent and teacher behaviour questionnaires and the Conner modification of the Rutter teacher questionnaire. Children attending normal schools were assessed with controls matched for age, sex, and class in school. Children attending special schools were assessed unmatched. SUBJECTS--233 matched case-control pairs attending normal primary schools and 46 unmatched children attending special schools. SETTING--Primary and special schools. MAIN OUTCOME MEASURES--Emotional, conduct, and undifferentiated behaviour disorders and hyperactivity. RESULTS--On the parental questionnaire screen, 36% of the cases and 22% of the controls had a behaviour disorder and on the teacher questionnaire the proportions were 27% and 12% respectively. Hyperactivity was significantly more common among male cases than their controls (21% v 5.0%) but differed little among female cases and controls (9% v 7%). CONCLUSIONS--Improving neonatal survival of low birthweight infants is accompanied by a higher prevalence of behaviour disorders. The long term implications for psychiatric morbidity and other adult disease must be monitored.     

BENIGN GASTROCOLIC FISTULA ASSOCIATED WITH PERITONITIS

SUMMARY Gastrocolic fistula is most often related to malignancy or previous gastric surgery. It is an uncommon complication of benign gastric ulceration in patients who have not had a previous operation. Benign gastrocolic fistula associated with peritonitis is extremely rare — this case is only the fourth ever reported. The patient presented with an acute abdomen, and subsequent investigations demonstrated a gastrocolic fistula of benign aetiology.     

Compound heterozygosity for two genotypes of alpha-thalassemia-2: hematological, biosynthetic and DNA studies

Hemoglobin and DNA gene analyses were carried out in two Black Canadian families. In Family Q, both the parents and the brother were found to be heterozygotes for alpha-thalassemia-2 with the following alpha-genotypes: -alpha 3.7/alpha alpha, -alpha 4.2/alpha alpha and -alpha 4.2/alpha alpha, respectively. In Family C, the mother was found to be a homozygote for alpha-thalassemia-2 with the alpha-genotype of -alpha 3.7/-alpha 3.7. In both families, the propositi were compound heterozygotes for alpha-thalassemia-2 with the alpha-genotype of -alpha 3.7/-alpha 4.2. The propositus in Family C was also a sickle cell trait carrier. The usefulness of DNA gene analyses in family studies of hemoglobinopathy was discussed.
