The "information explosion" in the last 20 years has created a need for technique that synthesizes information from various sources. One of the methods for synthetasing information from various independent but similar studies is meta analysis. The aim of this study was to estimate complication rate of endomyocardial bi…

To demonstrate the advantages of various endoscopic hemostatic methods (laser photocoagulation, electrocautery, injection therapy) for bleeding gastroduodenal ulcer in patients at high risk for continued or recurrent bleeding, a critical review of published randomized clinical trials was made with meta-analytic methods…

While the loss of a parent during childhood may put a person at risk for depression, many studies have failed to confirm the importance of this risk factor. Nevertheless, the relationship between the loss of a parent and depression is of clinical importance. This paper reviews studies of the loss of a parent as a risk…

Oral enteric vaccines are reviewed with particular reference to cholera and typhoid. Enterotoxigenic E. coli, Shigella and Rotavirus vaccines are also considered. Clinical trials of those potentially useful vaccines are surveyed.

Results of numerous independent studies suggest that families of a critically ill hospitalized member have similar needs that they can readily identify as very important. Empirical analysis of results compiled from many studies across patient populations, settings, geographic locations, and over time indicates that fam…

To clarify the role of radiation therapy in the treatment of carcinoma of the pancreas studies with radiotherapy alone, combined interventional or concurrent radio-chemotherapy are reviewed. It is shown that in the case of inoperable tumour radiotherapy alone is inadequate, but by the means of a combination of chemothe…

Pharmacologic choices afford physicians the opportunity to tailor drug therapy to the individual patient's profile, and we are bolstered by a broad understanding of controllable risk factors. Choice of regimen--whether or not it involves drugs--requires accurate diagnostic information. Success depends on both control o…

We report 34 infections by Plasmodium ovale found among 15,806 blood film examinations taken between 1973 and 1989 from several sites in Indonesia. Twenty five of the P. ovale infections occurred in a single sample of 514 people living in Owi, Irian Jaya. We detected five additional infections at 3 other sites in Irian…

This article presents the state of the art of immunoscintigraphy (IS) of ovarian cancer. We will review the monoclonal antibodies (MoAbs) used in clinical trials: (HMFG1/2, OC125, H317, H17E2, NDOG2 and 791T/36). We conclude that none of the afore mentioned MoAbs are clearly superior and that IS cannot yet replace lapa…

OBJECTIVES: To compare the effects of different interventions for maintaining smoking abstinence in postpartum individuals. METHODS: We searched PubMed, EMBASE, CENTRAL, CINAHL, PsycINFO, and ProQuest up to February 2024. Randomized controlled trials (RCTs) that studied the effects of any interventions on maintaining…

A systematic review (SR) is the unbiased appraisal of systematically identified relevant studies. Implicit in its definition is a robust and scientifically valid process, and when performed as such, SR is an important clinical research tool and influence in health policy decision-making. This educational paper outlines…

BACKGROUND: With almost a million people dying by suicide worldwide each year, reducing the rate of suicidal behaviour is a priority in many countries. AIMS: To examine whether additional psychosocial interventions following an episode of self-harm reduce the likelihood of subsequent suicide. METHOD: We conducted a s…

Despite official support for the efficacy of cholesterol reduction, considerable controversy exists, and meta-analyses of this topic have produced conflicting results. The authors assessed the variability of meta-analyses, evaluating the cardiovascular value of cholesterol reduction while attempting to explain the vari…

Photoparoxysmal responses (PPRs) are generalized epileptiform abnormalities occurring during photic stimulation. Prolonged PPRs, which outlast the stimulus, can be distinguished from self-limited PPRs, which cease spontaneously or when the flashes stop. Reilly and Peters (1973) found a higher incidence of seizures in p…

Geographical differences may exist in the risk of gastric stump cancer. Therefore, we performed meta-analysis of literature reports in Japan (n = 3), the USA (n = 4), and Europe (n = 20) on the risk of postgastrectomy cancer. The weighted mean relative risk of stump cancer in Japan was 0.28, 95% confidence limits 0.21-…

BACKGROUND: Colorectal cancer survivors frequently experience persistent fatigue, psychological distress, and reduced health-related quality of life (HRQoL) after treatment. Exercise is increasingly recognized as an effective nonpharmacologic intervention, but the comparative efficacy of different modalities remains un…

BACKGROUND: Chronic low back pain (CLBP) is a prevalent musculoskeletal disorder. Electrotherapy modalities such as high-frequency transcutaneous electrical nerve stimulation (HF-TENS), low-frequency transcutaneous electrical nerve stimulation (LF-TENS), and interferential current (IFC) are commonly used, yet their com…

OBJECTIVE: Considering safety and effectiveness of oral antihypertensive agents when treating hypertensive disorders of pregnancy, no preference can be stated between the 3 agents currently available. Therefore, this systematic review and network meta-analysis aims to determine the effects of antenatal treatment with m…

Subdiaphragmatic irradiation remains the standard treatment for patients with stage I and IIA testicular seminoma. Elective mediastinal irradiation is not indicated. In well-selected patients with stage I disease, aggressive surveillance may be a reasonable alternative to elective irradiation. We believe that bipedal l…

The authors review 24 double-blind placebo-controlled studies comparing fluoxetine or bupropion against previously available antidepressants, to assess where there is evidence for a difference in the speed of onset of antidepressant action. Critical comparison of the studies showed no difference in speed of onset of ac…
