Management of genital burns: A review

We review the etiology and the management strategy of genital burns. The incidence of genital burns ranges from 2.8 to 13%. Most are part of larger injuries. Scald burns are typical for children, whereas flame and chemical burns happen more often in adults. For first and second‐degree genital burns, a conservative approach with physiological dressings and topical antimicrobials is advised. Only third degree burns need to be treated with removal of necrotic tissue and grafting. Indwelling catheters or suprapubic drainage systems must be avoided whenever possible.     

Communication between physicians and with patients suffering from breast cancer

BACKGROUND: The communication between GP and specialists is vital for the patient suffering from breast cancer. OBJECTIVES: The aim of this study was to investigate (i) the speed and type of communication between GPs, specialists and patients with breast cancer, and (ii) the problems that GPs encounter in the communication with specialists concerning these patients. METHOD: In April 1995, 246 Dutch GPs from the Zwolle region (600 000 inhabitants) were invited to complete a questionnaire, using the information from the medical record and focusing on the last patient consulted with a confirmed diagnosis of breast cancer. RESULTS: Valid replies were received from 150 (61 %) GPs. The median period between initial referral date and receipt of the definite diagnosis from the surgeon was 4 weeks. After the patient's first appointment with the surgeon, the GPs received reports for 24% of the patients within 3 days; for 31% within 3-7 days; and for 16% of the patients after more than 2 weeks. After the first consultation between patient and surgeon, 68 (45%) of the 150 GPs reported that the patient contacted them; at this stage only 30 (20%) of these GPs had received a report from the surgeon. Thirty-one (21%) GPs did not contact the patient after receival of the definite diagnosis. GPs stated that the communication on patients with breast cancer is too slow (49%), or not frequent enough (25%); 25% of GPs found that the distribution of tasks between them and the specialists are not well described. CONCLUSION: In the diagnostic stage of breast cancer the communication between GPs, specialists and patients varies widely, is too slow and is incomplete. An effect of this unsatisfactory communication is that the patient herself is the messenger of the bad news.      

Automatic implantable cardioverter-defibrillator: radiographic appearance

The automatic implantable cardioverter-defibrillator is used in patients with ventricular tachyarrhythmias resistant to medical or surgical therapy. The device, which has a unique radiographic appearance, senses ventricular tachycardia or fibrillation and automatically delivers a cardioverting or/defibrillating electric shock.     

Arrhythmias in general practice: diagnostic value of patient characteristics, medical history and symptoms

BACKGROUND: Complaints possibly caused by arrhythmias are frequently seen in general practice. It is unclear to what extent such complaints can differentiate between arrhythmias and other pathology in general practice. OBJECTIVES: We aimed to assess the value of symptoms (a) in diagnosing arrhythmias in general practice and (b) in identifying patients with clinically relevant arrhythmias. METHOD: During a 2-year period, a structured history from 762 patients with new complaints possibly related to an arrhythmia was taken by the GP, and a transtelephonic electrocardiogram (ECG) was made. RESULTS: In 28.3% of the patients, arrhythmias were detected and 8.8% were clinically relevant. Several patient characteristics, symptoms and medical history findings have high predictive values in diagnosing arrhythmias. In the logistic regression analysis, age and, to a lesser extent, male gender, palpitations and dyspnoea during consultation and the use of cardiovascular drugs are associated with the presence of arrhythmias. In detecting clinically relevant arrhythmias the same parameters apart from gender are important, as well as a history of arrhythmias. The use of central nervous system medication and frequent psychosomatic complaints are negatively associated with the presence of clinically relevant arrhythmias. CONCLUSIONS: In general practice, patient characteristics, symptoms and medical history findings can be used in the detection of arrhythmias and the assessment of their severity. They can help in the decision of whether to make an ECG recording.      

The effect of the antimycotic itraconazole on the pharmacokinetics and pharmacodynamics of diazepam

Summary— The azole antimycotic itraconazole is a potent and relatively unspecific inhibitor of cytochrome P450 enzymes and has a potentially dangerous interaction with midazolam and triazolam. The possible interaction between itraconazole and diazepam was investigated in a double-blind, randomized, cross-over study. Ten healthy volunteers were given orally placebo or itraconazole 200 mg a day for 4 days. The challenge dose of 5 mg of diazepam was ingested on the fourth day, after which plasma samples were collected and psychomotor performance tests were carried out for 42 h. Despite a statistically significant small increase in the area under the plasma diazepam concentration-time curve and the elimination half-life of diazepam, there was no clinically significant interaction as determined by the psychomotor performance tests. The lack of significant first-pass metabolism and the different metabolic pathways of diazepam explain the smaller interaction potential of diazepam compared with midazolam and triazolam. Diazepam, unlike midazolam and triazolam, can be prescribed in usual doses for patients receiving itraconazole and probably other inhibitors of P4503A4, at least when diazepam is used as single doses.
