Randomized double-blind trial of metronidazole versus secnidazole in amebic liver abscess.

OBJECTIVE: To compare the efficacy of secnidazole with metronidazole in the treatment of amebic liver abscess. METHODS: Thirty two patients with uncomplicated liver abscesses were studied in a randomized, double-blind trial. Fifteen received metronidazole (400 mg t.i.d. for 7 days) and 17 secnidazole (500 mg t.i.d. for 5 days). All abscesses were aspirated on day 1 and laboratory tests and ultrasonographic examination were done on days 1 and 10. RESULTS: One patient in the metronidazole group developed intraperitoneal rupture. The other 31 patients had 40 abscesses (19 in metronidazole group, 21 in secnidazole group). Complete resolution of signs occurred by day 10 in 10 patients on metronidazole and 12 on secnidazole, and in all others by day 28. On day 10 ultrasonography in the metronidazole group showed complete disappearance of abscess in one patient, decrease in 8 and increase in 5 (versus 2, 12 and 3, respectively in the secnidazole group). After 6 months, four asymptomatic patients (two from each group) had small abscess cavities on ultrasonography; there were no recurrences. CONCLUSIONS: Secnidazole is as effective in the treatment of amebic liver abscess as metronidazole; it is equally well tolerated.

Evaluation of cardiac function in iron deficiency anemia before and after total dose iron therapy.

OBJECTIVE: To evaluate the cardiac function before and after the total dose iron therapy (TDI) and to correlate the myocardial function to the rise in haemoglobin after TDI in patients of iron deficiency anemia. METHODS: The study included 30 patients of iron deficiency anemia who presented to our institution in the last one year. There were 11 men and 19 women with the mean age of 30 years. Parameters compared before and after TDI infusion included clinical features, haemoglobin, electrocardiogram (ECG), treadmill stress test (TST) and 2 dimensional echocardiogram (2D echo). RESULTS: During the study period 30 patients (11 men and 19 women) were included for TDI. The mean haemoglobin level increased from 5 gm/dl to 5.7 gm/dl 4 days after TDI. The congestive cardiac failure disappeared in four out of eight patients after TDI. The mean heart rate on the ECG pretherapy was 102.66 +/- 14.9 and post therapy 93.4 +/- 14.9 (p = 0.011). The TST results showed improvement in effort tolerance in 17 out of 24 patients (p = 0.0012) and it improved much before there was a significant rise in haemoglobin. CONCLUSION: Impaired ventricular performance is observed in patients with iron deficiency anemia. After TDI the left ventricular function improved before there was a significant rise in haemoglobin level proving the theory that correction of the electrophysiological abnormalities of the heart in iron deficiency patient by TDI may be the result of correction of iron at the tissue level.

Allergic bronchopulmonary aspergillosis.

A 38 year old male was diagnosed to have allergic bronchopulmonary aspergillosis which responded remarkably to prednisolone therapy.

Metoclopramide for preventing pneumonia in critically ill patients receiving enteral tube feeding: a randomized controlled trial.

OBJECTIVE: To determine whether metoclopramide prevents nosocomial pneumonia in intensive care unit (ICU) patients receiving enteral feeding by a nasogastric tube. DESIGN: Prospective, randomized, controlled trial. SETTING: ICU of a university hospital. PATIENTS: A total of 305 consecutive patients requiring placement of a nasogastric tube for >24 hrs. INTERVENTIONS: Patients were randomized to receive either 10 mg of metoclopramide or placebo at 8-hr intervals through the nasogastric tube. MEASUREMENTS AND MAIN RESULTS: A total of 174 patients received placebo and 131 received metoclopramide. Baseline characteristics in the two treatment groups were comparable. Of the 305 patients, 46 developed nosocomial pneumonia, which was 24 patients (13.7%) in the placebo group and 22 (16.8%) in the metoclopramide group (p > .05). Patients in the placebo group developed pneumonia earlier than patients receiving metoclopramide (4.46+/-1.72 days [mean +/- SD[rsqb] after ICU admission compared with 5.95+/-1.78 days; p = .006). Subgroup analysis showed that metoclopramide did not reduce the frequency rate of pneumonia in patients with tracheal intubation (19 [25.3%] of 75 patients receiving metoclopramide vs. 21 [21.2%] of 99 patients receiving placebo) or those receiving mechanical ventilation (17 [25.6%] of 58 patients receiving metoclopramide vs. 20 [29.3%] of 78 patients receiving placebo). The mortality rate also did not differ in the two treatments groups (56% in the metoclopramide group vs. 53% in the placebo group; p > .05). CONCLUSIONS: Although metoclopramide delayed the development of nosocomial pneumonia, it did not decrease its frequency rate and had no effect on the mortality rate in critically ill patients receiving nasogastric enteral feeding.

Facial nerve involvement in pseudotumor cerebri.

A woman with history of bifrontal headache, vomiting and loss of vision was diagnosed as a case of pseudotumor cerebri based on clinical and MRI findings. Bilateral abducens and facial nerve palsies were detected. Pseudotumor cerebri in this patient was not associated with any other illness or related to drug therapy. Treatment was given to lower the raised intracranial pressure to which the patient responded.
