Corynebacterium haemolyticum septicemia in a girl with mononucleosis infectiosa

Many isolates of Corynebacterium are dismissed as contaminants by technicians and microbiologists in the laboratory. We report the isolation of Corynebacterium haemolyticum from the blood of a 15-year-old girl with mononucleosis infectiosa and conclude that this species should be considered as a possible pathogen and not only be regarded as innocent bacteria, particularly in the immunocompromised host.     

Selective transport of an oligomeric IgA into canine saliva

Evidence is presented which shows that an oligomeric IgA myeloma protein possessing J-chain but lacking secretory component, is selectively transferred from serum into canine saliva. The data also demonstrate that 125I-label remains with the IgA during the transfer process. These data interpreted in the light of findings in humans support the concept that the oligomeric form of IgA, devoid of secretory component, is required to achieve selective transport.     

The consult is real,the visit is virtual

A web-based service was developed through which patients can obtain second opinions from physicians. Factors addressed included incorporating e-appointments into a medical practice, consolidating different approaches to second opinions, complying with disparate state licensing regulations, and communicating the program's features to providers and patients.     

Summary of the practice guideline 'CVA' from the Dutch College of General Practitioners

The practice guideline 'CVA' from the Dutch College of General Practitioners provides guidelines for the management of stroke patients. The guideline is in agreement with the changing insights about the benefits of stroke-units and thrombolysis. The most important recommendations are the following. In the acute phase, most patients with a cerebrovascular accident should be referred for admission to a stroke-unit. Exceptions are patients with only slight neurological disability and patients with severe comorbidity. Patients with a CVA that started less than three hours ago should be referred for emergency thrombolytic therapy in regions where this possibility exists. In situations in which the general practitioner considers a home visit to involve an unacceptable loss of time, he may decide to refer on the basis of the results of the 'face-arm-speech-time' (FAST) test, which can be administered by telephone. For patients that remain at home, the general practitioner sees to the early start of a rehabilitation programme, and takes the initiative if necessary. The general practitioner can support stroke patients with permanent neurological deficits by considering them to be chronically ill patients requiring regular check-ups.     

Prognostic variables for high titres in a fluorescent antibody test to diagnose tuberculosis

SETTING: The four hospitals and a tuberculosis clinic in the province of Zeeland, The Netherlands. OBJECTIVE: To assess the usefulness of PPD antibody measurement in the diagnosis of tuberculosis in patients admitted to hospital. PATIENTS AND METHODS: Sixty-one patients presenting with active tuberculosis, and 215 control patients were included in the study. Initial serum PPD antibody titres were determined with a macrophage uptake Fluorescent antibody test (MuFat) to construct a discrimination model between Tuberculosis (TB) and non-TB. We also retrospectively collected clinical parameters of the TB patients at presentation. Univariate and multivariate logistic regression are used to identify variables predicting high antibody titres. RESULTS: In TB patients, the presence of clinical symptoms (OR=10.63) and the presence of at least two concurrent non-lymph node disease localizations outside thorax and abdomen (OR=13.94) are necessary and sufficient to predict high titres. The logistic model shows a significant contribution of the 2log (titre) to the discrimination between TB and non-TB patients. At a cut-off value of 128, a specificity, sensitivity, and positive predictive and negative predictive values of 97%, 39%, 80% and 85%, respectively, are calculated in the study cohort. CONCLUSION: Our data suggest an application of the test at high cut-off values for timely diagnosis of difficult-to-diagnose TB patients. The results of this retrospective study will have to be confirmed in further prospective studies.     

Starting insulin in type 2 diabetes: continue oral hypoglycemic agents? A randomized trial in primary care

OBJECTIVE: To evaluate the effects of insulin 30/70 twice daily or bedtime isophane (NPH) insulin plus continued sulfonylurea and metformin in patients with type 2 diabetes in primary care. STUDY DESIGN: Open-label, randomized trial. POPULATION: Persons younger than 76 years with type 2 diabetes whose disease had not been controlled with oral hypoglycemic agents alone. A total of 64 insulin-naive patients treated with maximal feasible dosages of sulfonylurea and metformin (baseline glycosylated hemoglobin [HbA1c]=8.5%) were randomly assigned to insulin monotherapy (IM group; n=31) or insulin in addition to unchanged oral hypoglycemic medication (IC group; n=33) for 12 months. Insulin doses were adjusted to obtain fasting glucose <7.0 mmol/L and postprandial glucose <10.0 mmol/L. OUTCOMES MEASURED: Outcome measures included HbA1c, treatment failure, weight, hypoglycemic events and symptoms, satisfaction with treatment, general well-being, and fear of injecting insulin and testing. RESULTS: HbA1c improved from 8.3% to 7.6% in the IC group, and from 8.8% to 7.6% in the IM group (P=NS). The IC group had 24% treatment failures, compared with 2% in the IM group (P=.09). Patients in the IC group had less weight gain than those in the IM group (1.3 vs 4.2 kg; P=.01), and they reported fewer hypoglycemic events (2.7 vs 4.3; P=.02). Increased satisfaction with treatment was equal in the 2 groups, and general well-being improved by 3.0 points more in the IC group (P=.05). Fear of self-injecting and self-testing did not differ. CONCLUSIONS: Bedtime NPH insulin added to maximal therapy with sulfonylurea and metformin is an effective, simple, well-tolerated approach for patients with uncontrolled type 2 diabetes.     

Summary of the practice guideline 'Hearing impairment' (first revision) from the Dutch College of General Practitioners

The Dutch College of General Practitioners recently issued a revised version of the practice guideline 'Hearing impairment'. The modification of the screening for hearing impairment, which now takes place in neonates, has resulted in a much lower number of false-positive diagnoses of perceptive hearing loss than under the previous version of the practice guideline. The expanded diagnostic possibilities for adults, whether or not implemented by the patients themselves, demand an active approach from the general practitioner towards patients with impaired hearing. This guideline helps general practitioners to select patients that will truly benefit from a hearing aid and that will also be more likely to use one. The general practitioner can play an important role by stimulating patients to be referred for a hearing aid.
