BACKGROUND: A large outbreak of poliomyelitis due to poliovirus type 3 (P3) occurred in India in 1999. This raised concerns about oral poliovirus vaccine (OPV) effectiveness, particularly the type 3 component, in preventing clinical disease and offered an opportunity to describe the epidemiology of a P3 outbreak. METHODS: We reviewed ...

AIM: Granulomatous mastitis is a rare condition of unknown aetiology. The great majority of cases has not been associated with bacterial pathogens if women with mammary tuberculosis are excluded. We noted that some women in Auckland with a histological diagnosis of granulomatous mastitis had both microbiological and histological evidence of ...

A case-control study of the management and disease risk factors associated with toxic mastitis in cows was carried out. Seventy-one cases satisfied all the selection criteria, and a subset of 41 cases in which pure growths of Escherichia coil were cultured from milk samples was also investigated. Conditional multiple logistic ...

'Flashbacks' following use of hallucinogenic drugs have been reported for decades; they are recognized in DSM-IV as 'Hallucinogen Persisting Perception Disorder (Flashbacks)', or HPPD. We located and analyzed 20 quantitative studies between 1955 and 2001 examining this phenomenon. However, many of these studies were performed before operational criteria for HPPD ...

Mycosis fungoides (MF) is a rare disease with an unknown aetiology, although it has been suggested that infections may play a role. The present study investigates whether infections, atopic disorders and some other diseases are risk indicators for MF. A European multicentre case-control study involving seven rare cancers, including MF, ...

The goal of this study was to determine the causes of increased post-arthroscopy surgical site infections (SSIs) and to define risk factors for infection. Outbreak investigation and case control study at a university-affiliated community hospital from 1994 to 1996, with surveillance through 1999. Demographic, clinical, and microbiological data were collected ...

Oxidative stress is widely thought to contribute significantly to the pathogenesis Parkinson's disease (PD). Given the role of glutathione S-transferases (GSTs) in the conjugation of electrophiles and protection against reactive oxygen species, genes encoding the GSTs have been considered candidates for association studies of PD. We tested for associations between ...

The use of a child as a case's control in a case-control study of genetic factors may be advantageous in some situations. We describe three methods of analysing such data. A method based upon the unconditional likelihood using case/child pairings apparently is the most efficient method. However, a conditional likelihood ...

Some studies have been carried out to analyze human female first meiotic prophase. Most of them use samples from foetuses collected after legal interruption of pregnancy. In some cases, a control population is needed and foetuses aborted for non-chromosomal reasons are used. The assumption of these samples as being euploids ...

We report a case of gynaecologic haemorrhage after a Piver type-3 procedure treated by a packing technique. The postoperative course was uneventful and the packs were removed after six days. Intra-abdominal packing should be familiar to both obstetricians and gynecologists because when any other attempt to provide hemostasis fails, it ...

BACKGROUND: beta-Carboline alkaloids are normal body constituents but are also potent tremor-producing chemicals that are naturally present in the food chain. OBJECTIVE: To explore the hypothesis that high concentrations of beta-carboline alkaloids are associated with essential tremor (ET). METHODS: One hundred cases and 100 controls were frequency matched on age, ...

Intractable paroxysmal sneezing is a rare disease primarily affecting teenage girls. We present the case of a 12-year-old girl who demonstrated the classical features of intractable paroxysmal sneezing of psychogenic origin. Most of the reported cases are psychogenic in origin, but a number of other conditions may cause intractable paraoxysmal ...

BACKGROUND: Anencephaly has been associated frequently with intrauterine growth retardation (IUGR), consistently with adrenal hypoplasia, and occasionally with an enlarged thymus. Few studies have analyzed the relationship between gestational age (GA), IUGR, associated anomalies and thymomegaly in anencephaly. The aims of our study were to evaluate this relationship and to ...

It is widely recommended that all hemodialysis grafts undergo blood flow (Qa) surveillance, and that stenosis be corrected when accompanied by a low Qa or decrease in Qa (deltaQa). This recommendation has, however, become increasingly controversial. Studies have shown that although there is an association between Qa and thrombosis, the ...

Debate continues about whether and to what extent travel predisposes to venous thrombosis and pulmonary embolism (PE). Almost certainly, the strength of any association was greatly exaggerated in recent press reports. Conclusions from case-control studies vary, with some finding no excess of recent travel among patients with venous thromboembolism and ...

The combined investigation of environmental and genetic risk-factors in complex traits will refocus attention on the case-control study. Endometriosis is an example of a complex trait for which most case-control studies have not followed the basic criteria of epidemiological study design. Appropriate control selection has been a particular problem. This ...

In a family-matched case-control study, a population-based sample of cases is selected from a well-defined geographic region over a fixed period of time. For diseases of adult onset, the control is generally a sibling or cousin who is matched on sex and age without regard to location of residence. Such ...

Hypertrophic pulmonary osteoarthropathy (HPOA) may complicate the advanced lung disease that is associated with cystic fibrosis, resulting in severe joint pain and early-morning stiffness. Symptoms are usually controlled with the administration of nonsteroidal anti-inflammatory drugs, physiotherapy, and, on occasions, oral corticosteroids. This report describes a case of refractory HPOA with ...

Although low participation in case-control studies may threaten their validity, it is difficult to evaluate the potential problem of nonresponse across studies because the level of participation among subjects is not reported in a consistent manner. This commentary presents a proposal for standard reporting of the process by which control ...

This study addressed methodological issues of epidemiologic studies on venous thromboembolism (VTE) to show how design decisions can affect the results. It examines the influence of a restricting to hospitalized and to "idiopathic" cases of VTE in case-control studies on VTE risk and oral contraceptive (OC) use and thereby the ...

Many reports have described loss of neurons in the substantia nigra in Pick's disease (PiD). In those reports, however, "Pick's disease" includes PiD without Pick bodies (PB), and there is only limited data available on regional nigral pathology in PiD with PB. To elucidate the pathological changes of the substantia ...

Dams are controversial: their positive results include electricity generation, flood control, and irrigation; negative effects include population displacement and ecological impacts. A fair assessment can only be made on a case by case basis, judging individual projects in their individual context, and using holistic and interdisciplinary approaches. Decisions can no ...

The first modern case-control study was Janet Lane-Claypon's study of breast cancer in 1926, but the design was used only sporadically in medicine and the social sciences until 1950, when four published case-control studies linked smoking and lung cancer. These 1950 studies synthesized the essential elements of the case-control comparison, ...

An association between the use of Viadent toothpaste and/or mouthwash and the development of leukoplakia oral mucosal lesions has been described recently. Discontinuing the Viadent products may result in resolution of the leukoplakia, although frequently this is not the case. In order to corroborate the earlier study and to provide ...
