Abstract
Hepatitis is a well-recognised complication of Epstein-Barr virus (EBV) infection that usually resolves spontaneously. Jaundice occasionally results from the unusual complication of autoimmune haemolytic anaemia rather than hepatitis. Two adult patients are described with infectious mononucleosis-related hepatitis who also developed significant haemolysis, a situation that could have led to diagnostic delay and a deleterious outcome. Haemolysis should be considered in all patients who become jaundiced after infectious mononucleosis. The management of this potentially fatal complication is discussed.

Abstract
Isolates of Mycobacterium tuberculosis from 88 patients with pulmonary tuberculosis in northern Tanzania were subjected to IS6110 restriction fragment length polymorphism (RFLP) analysis. Of 88 isolates, 73 fell into 11 groups of which 9 contained 2-5 isolates. Of 2 large homology groups one, group H (20 isolates), was isolated only from patients resident in the Kilimanjaro region, whereas 79% of isolates from other groups came from this region. A significant association (P = 0.023) was found between another group, M (24 isolates) and isolation from patients of the Masai tribe. The data from this pilot study support the idea that IS6110 RFLP analysis provides information which may be of value in the control of tuberculosis in Africa.

Abstract
The use of the polymerase chain reaction (PCR) for assessing treatment response in tuberculosis was investigated. Serial sputum samples were analyzed from 10 Tanzanian patients treated for smear-positive pulmonary tuberculosis, including 4 who relapsed after initially successful treatment. A one-tube nested PCR with a colorimetric detection system was compared with microscopy and culture. Samples were found to be negative by microscopy before they were by PCR or culture, often remaining positive 1-2 months longer by PCR than by culture. For the 76 samples available for both culture and PCR, there was a 76% (58/76) agreement between the methods. Nine samples were negative by culture but positive by PCR; 7 were either negative (5) or equivocal (2) by PCR despite being positive by culture. Two of the 4 relapse cases were detected earlier by PCR than by culture. These results demonstrate that PCR is a promising method for assessing treatment response in pulmonary tuberculosis.

Abstract
Immunoscintigraphy with CYT-103, an 111indium-labelled immunoconjugate of B72.3, was evaluated in 10 patients before surgery for suspected or biopsy-proven primary colorectal cancer. The imaging results were compared with computed tomography (CT) findings at surgery, histopathology and immunohistochemistry. There were no adverse reactions following the administration of 1.0 mg 111In-CYT-103. Surgical and pathological findings identified 15 sites of disease (10 primary and five metastatic) and all but one lesion (severe dysplasia) were malignant. CT detected nine of 14 sites of malignancy compared to 12 as identified by immunoscintigraphy. It failed to detect two primary lesions and one case of peritoneal metastasis, all of which were imaged by CYT-103. Both imaging modalities failed to detect two of three cases with lymph node metastases and the dysplastic lesion (true negatives). The results indicate that 111In-CYT-103 imaging exhibits high sensitivity and specificity in the detection of primary and secondary lesions in patients with colorectal cancer.

Abstract
Bacterial meningitis secondary to CSF rhinorrhoea is well recognised. We present a case of meningitis due to Haemophilus influenzae type b associated with a CSF fistula. The patient was 40 years of age at presentation, having sustained a head injury when 3-years-old. He had suffered intermittent rhinorrhoea for 18 months before admission. Delays between head injury and meningitis are well recognised, but our case may represent the longest recorded interval. H. influenzae meningitis in adults is discussed.

Abstract
The early bactericidal and sterilizing activities of ciprofloxacin were evaluated in the treatment of adult patients with smear positive pulmonary tuberculosis. Two randomized prospective studies were performed in Northern Tanzania. In study 1, ten patients received either 750 mg ciprofloxacin or 300 ng isoniazid daily for 7 days. Counts of colony-forming units (cfu) of Mycobacterium tuberculosis in early morning sputum were performed. In study 2, twenty patients received either a standard regimen of rifampin (R), isoniazid (H), pyrazinamide (Z), and ethambutol (E) (regimen HRZE) or a trial regimen of ciprofloxacin (C), isoniazid (H), and rifampin (R) (regimen HRC). Sputum colony counts were performed for 8 wk. Patients were tested for antibodies to human immunodeficiency virus (HIV)-1. The results demonstrate that ciprofloxacin alone has useful early bactericidal activity, resulting in a mean daily fall of 0.20 log10cfu/ml/day during 7 days compared with 0.25 log10cfu/ml/day for isoniazid. When HRZE and HRC regimens were compared, the HRC regimen appeared to be inferior in its sterilizing ability, with a culture conversion rate of 67% at 2 months compared with 100% for HRZE. The difference in outcome was most marked in HIV-1 positive patients. The role of ciprofloxacin in combination regimens may be as a bactericidal rather than a sterilizing agent.

Abstract
Brain natriuretic peptide (BNP) is a cardiac ventricular hormone that may be a sensitive and specific marker of changes in ventricular function. In a prospective, randomised open trial with 16 patients followed for 6 months after first Q wave anterior myocardial infarction we set out to determine: whether BNP concentrations are raised acutely, the effect on circulating BNP of angiotensin-converting enzyme (ACE) inhibition, how BNP and atrial natriuretic peptide (ANP) concentrations compared as correlates of left-ventricular ejection fraction, and whether plasma BNP concentrations could distinguish patients with low (< 40%) and relatively preserved (> 40%) ejection fractions. Plasma concentrations of BNP measured on days 2, 7, 8, 42, and 180 postinfarction were significantly raised in patients compared with normal controls and to a proportionately greater degree than ANP concentrations. Treatment with placebo (n = 8) or oral captopril (n = 8) from day 8 resulted in significantly lower BNP concentrations at days 42 (p = 0.05) and 180 (p < 0.05) in the captopril-treated group. Compared with ANP, BNP concentrations were much more strongly correlated with radionuclide-measured left-ventricular ejection fraction at days 2, 42, and 180. All 8 patients with baseline (day 2) ejection fractions of 40% or above had plasma BNP concentrations less than 10 pmol/L, whereas the 8 patients with ejection fractions less than 40% had BNP concentrations greater than 10 pmol/L. Our findings suggest that measurements of circulating BNP may identify those patients with significant left-ventricular dysfunction who have been highlighted by the Survival and Ventricular Enlargement study as likely to benefit from long-term ACE inhibition after myocardial infarction.

Abstract
The purpose of this investigation was to study whether favorable renal effects might contribute to the influence of captopril in offsetting ventricular dilatation after infarction. Effective renal plasma flow and glomerular filtration rate were estimated by isotope injection methods in 20 patients on days 2, 7, 8, 42 and 180 after a first transmural anterior myocardial infarction. After measurements on day 7, patients were randomized to receive either captopril 25 mg 3 times daily (n = 10) or placebo (n = 10) for the remainder of the study. At baseline (day 7) there were no differences between the 2 treatment groups in radionuclide left ventricular ejection fraction, effective renal plasma flow, glomerular filtration rate or neurohormones. Left ventricular ejection fractions (40 +/- 4% [mean +/- 2 SD] at baseline) were higher in the captopril- than the placebo-treated patients on days 42 (p < 0.05) and 180 (p < 0.01) after infarction. Effective renal plasma flow became significantly higher at all time points after randomization in the captopril-treated group than in the placebo group (p < 0.001). A similar but lesser trend was observed for glomerular filtration rate. Plasma atrial natriuretic factor and aldosterone were significantly higher in the placebo group (p < 0.05). Renal hemodynamic indexes were directly correlated with and neurohumoral indexes inversely correlated with ejection fractions. In a second group of 12 patients with higher baseline ejection fractions (48 +/- 4%) after an inferior infarction, none of these beneficial effects of captopril were demonstrable. It is proposed that in the setting of left ventricular dysfunction after infarction, a prompt and sustained improvement in renal hemodynamics, by reducing inappropriate fluid retention and thus ventricular preload, may be one contributory mechanism by which captopril prevents progression of left ventricular dilatation.

Abstract
The value of lacrimal scintigraphy in the assessment of nasolacrimal duct obstruction was determined by comparing the results with syringing in 67 patients (83 eyes). As expected, of 28 lacrimal drainage systems which were obstructed on syringing, 23 (82%) had abnormalities of tear drainage on scintigraphy. However, in 55 lacrimal drainage systems that were patent on syringing, 19 (35%) were normal, but in 36 (65%) abnormalities not apparent on syringing were detected on scintigraphy. Thus scintigraphy is a very useful technique in the assessment of nasolacrimal duct obstruction particularly in systems patent on syringing. Since the site of obstruction can be determined, lacrimal scintigraphy can facilitate the planning of the appropriate surgery.

Abstract
The effect of atenolol on dipyridamole 201Tl myocardial perfusion tomography was evaluated in 12 patients with angiographically proven coronary artery disease. The patients had dipyridamole 201Tl tomography performed after 7 days treatment with 50 mg atenolol and then repeated after a further 7 days treatment with placebo. The images were interpreted qualitatively by two experienced observers and quantitatively using the Bullseye technique. Qualitative analysis of the images revealed that four of the 12 patients had larger defects on their scans whilst receiving atenolol compared to placebo. The remaining eight patients had defects which were the same size on both treatments. The severity of defects assessed qualitatively was not significantly influenced by atenolol therapy (P = 0.13, McNemera's test). The results obtained with the Bullseye method did not demonstrate significant statistical differences for defect size, degree of reversibility or percentage reversibility whilst the patients were receiving atenolol or placebo (Wilcoxon Rank Sum Test). Atenolol increased the size of perfusion defects on dipyridamole 201Tl tomography qualitatively and quantitatively for four patients in this group of 12 with proven coronary artery disease. Although this did not achieve a high level of statistical significance physicians should be aware that atenolol can influence the images obtained at dipyridamole 201Tl tomography.

Abstract
There is a small, well-known cohort of patients who, despite classic reflux symptoms, have a normal esophageal pH profile and endoscopic picture. The treatment of these patients has proved problematic. In an attempt at determining the pathophysiology of this subgroup, we investigated the esophageal transit, using the radiolabeled solid bolus esophageal egg transit technique, in 58 such patients: 25 males, 33 females, mean age 39.5 years (range: 13 to 65 years). The egg transit was normal in 31 (53.4%) patients. In the remaining 27 (46.6%) patients, the condensed image analysis showed the following specific abnormal transit patterns: "step" delay pattern, demonstrating segmental hold-up in mid- or distal esophagus in 16 (59.3%); nonspecific delay in 6 (22.2%); oscillatory pattern in 3 (11.1%); and total nonclearance during the study period (4 minutes) in 2 (7.4%) patients. The patients with abnormal transit patterns had demographic parameters and symptom scores similar to those found in patients with normal transit. This study shows that almost 50% of patients with reflux symptoms and negative pH and endoscopy have abnormal esophageal transit, and almost two thirds of these patients display segmental transit delay in the lower half of the esophagus. The effect on symptomatology by prokinetic agents in the patient subgroup needs evaluation.

Abstract
A total of 110 consecutive females who presented in 1987 with primary carcinoma of the breast were staged according to the UICC TNM staging system. Of these, 90 patients had bone scans at presentation, of which seven were positive. The rate of positive initial scans for Stages I-II was 3.5%. Of these only one patient subsequently had bone metastases confirmed, to diagnose which by bone scan, the estimated cost was pounds 1300. Follow-up information was obtained for 95 patients, repeat scans being performed in 22 who had symptoms suggestive of bone metastases. Ten patients with negative initial scans converted to scan-positive within a mean time of 15 months. Only four of these had radiological confirmation of bone metastases. The cost of detecting bone metastases by follow-up scan was approximately pounds 80 per patient. The false-positive rate and the false-negative rate were both calculated as 10%. The specificity of the test was calculated as 90%. It is recommended that bone scanning should be reserved for patients with Stages III and IV disease and to evaluate symptoms suggesting bone metastases.

Abstract
A prospective multifactorial study of symptoms and disturbance of gastrointestinal function has been undertaken in 50 patients with non-ulcer dyspepsia. Objective tests including solid meal gastric emptying studies, gastric acid secretion, E-HIDA scintiscan for enterogastric bile reflux, and hydrogen breath studies were carried out in all patients and validated against control data. Gastroscopy and biopsy were carried out in non-ulcer dyspepsia patients only. Non-ulcer dyspepsia patients were categorised on the basis of predominant symptoms as: dysmotility-like dyspepsia (n = 22); essential dyspepsia (n = 14), gastro-oesophageal reflux-like dyspepsia (n = 11); and ulcer-like dyspepsia (n = 3). In the total non-ulcer dyspepsia population, solid meal gastric emptying was delayed (T50 mean (SEM) = 102 (6) minutes (patients) v 64 (6) minutes (controls), (p less than 0.01) and high incidences of gastritis (n = 26) and Helicobacter pyloridis infection (n = 18) were found. An inverse correlation was observed between solid meal gastric emptying and fasting peak acid output (r = -0.4; p less than 0.01). Indeed gastric emptying was particularly prolonged in eight patients (T50 mean (SEM) = 139 (15) minutes) with hypochlorhydria. In the non-ulcer dyspepsia population oral to caecal transit time of a solid meal was delayed (mean SEM = 302 (14) minutes (patients) v 244 (12) minutes (controls) (p less than 0.01]. Seven patients had a dual peak of breath hydrogen suggestive of small bowel bacterial overgrowth. No association was observed between symptoms and any of the objective abnormalities. This multifactorial study has shown that hypomotility, including gastroparesis and delayed small bowel transit, is common in non-ulcer dyspepsia and may be related to other disorders of gastrointestinal function. No relation between symptoms and disorders of function, however, has been shown.

Abstract
Six male children, aged 8-28 months, were studied for three consecutive periods of 1 week each. They were given diets that provided 1.7 g protein/kg per d and supplements of minerals and vitamins, with a metabolizable energy intake during the 1st, 2nd and 3rd week of 419, 293 and 335 kJ (100, 70 and 80 kcal)/kg per d, diets 1, 2 and 3 respectively. All the food offered was consumed. Each child was weighed at the same time each day on an electronic balance. On the 6th and 7th day of each study period urine and stool were collected for 24 h to assess nitrogen balance. Using linear regression analysis it was shown that all children gained weight on diet 1, 2.3 (SD 1.3) g/kg per d, and five of six children gained weight on diet 3, the mean for the whole group being 2.7 (SD 2.3) g/kg per d, not significantly different. On diet 2 all children lost weight, -5.4 (SD 1.3) g/kg per d, highly significantly different from each of the other dietary periods. Using asymptotic regression analysis it could be shown that the rate of weight loss during the first part of the week on diet 2, -11 g/kg per d, was greater than at the end of the week, -2 g/kg per d, with a tendency towards a steady weight by day 7. Apparent N retention (mg/kg per d) was positive at the end of each of the three dietary periods: diet 1, 112 (SD 25); diet 2, 54 (SD 34); diet 3, 82 (SD 20). In five of the six children there was a marked reduction in stool frequency on diet 2 compared with diet 1, that was maintained to the period on diet 3. The findings suggest that during the period on diet 2 there was a saving of energy of the order of 105 kJ (25 kcal)/kg per d, which lasted through into the period on diet 3.

Abstract
Patients with reflux oesophagitis have a diminished capacity for distal oesophageal clearance. This is considered to be secondary to acid reflux damage to the oesophageal wall. We have postulated that the observed oesophageal dysmotility is a primary phenomenon. Using 24 hour oesophageal pH monitoring and the solid bolus oesophageal egg transit test, we evaluated the oesophageal transit of 55 patients, with symptomatic reflux oesophagitis, and 16 healthy volunteers. The transit for the entire oesophagus was significantly prolonged in the patient group. This delay was evident in all three segments of the oesophagus. Amongst the patients, there was significant correlation between the oesophageal transit time and the number of prolonged reflux events. No correlation was found, however, between symptom score or severity of endoscopic oesophagitis and transit time. These results would indicate that the oesophageal dysmotility is an integral part of gastrooesophageal reflux disease, and is more of a cause than an effect.
