Cancer screening by primary care physicians: a comparison of rates obtained from physician self-report, patient survey, and chart audit.

OBJECTIVES. This study measured the cancer screening rates of family physicians and compared the measures obtained through physician self-reports, chart audits, and patient surveys. METHODS. A cancer screening survey was sent to 50% of the members of the Washington Academy of Family Physicians, with 326 family physicians (74% response rate) completing the survey. Sixty physicians were recruited for the patient survey and chart audit phase, with a 90% participation rate. Patient surveys were conducted with about 350 patients per physician, and chart audits were conducted on a subset of about 50 patients per physician. Each physician's rate of providing each service was computed from the self-report, the patient survey, and the chart audit. RESULTS. Physicians provided many of these services at rates different from those commonly recommended. Large discrepancies were found between the rates measured by different methods. Correlations between rates derived from chart audits and patient surveys were high; however, correlations between rates from physician self-report and either patient survey or chart audit were much lower for all services. CONCLUSIONS. Studies of physicians' provision of cancer prevention services should not rely on physician self-report, but should obtain the rates through patient surveys or chart audits.     

Retinal detachment in pseudophakia

Retinal detachment in an aphakic eye is a grave therapeutical problem. There exists some fears that cataract extraction with implantation of an artificial lens may increase the number of these complications. Three hundred and seventy cases of cataract extraction with implantation of an artificial lens performed in our department were analysed from the point of view of the incidence of retinal detachment. The cataract was extracted extra- and intracapsularly and the artificial lens was implanted in the anterior as well as in the posterior chamber. During the period of observation--4 months to 3 years--it was established that the number of the retinal detachment in pseudophakia was not larger than in aphakic eyes without implant.     

Association of HLA-DQA1*03011-DQB1*0301 haplotype with the development of respiratory scleroma.

OBJECTIVE: Respiratory scleroma (RS) is a progressive, chronic, granulomatous disease caused by Klebsiella rhinoscleromatis. There is only one report of RS association with HLA-DQ3. In this study, molecular association of HLA class II and RS was determined. STUDY DESIGN AND SETTING: Nine RS patients and 163 healthy controls were compared. DQA1, DQB1, and DRB1 loci were typed. RESULTS: Statistical analysis demonstrated association between DQB1*0301 and susceptibility to RS (P(c) = 0.004). Haplotype analysis showed an association of DQA1*03011-DQB1*0301 (P = 1.21E-19) and DRB1*0407-DQA1*03011-DQB1*0301 (P = 0.0002). CONCLUSIONS: Results established that DQA1*03011-DQB1*0301 haplotype is a strong risk factor for development of RS.     

Rare testicular tumors. Apropos of 15 cases

In a series of 141 patients treated over the last ten years for testicular tumour, 15 presented lesions considered to be rare: 9 Leydig cell tumours, 3 epidermoid cysts, 1 leiomyoma, 1 primary testicular lymphoma and one testicular localisation of a known leukaemia. The clinical, endocrine and histological features of these different tumours are reviewed on the basis of the present series and a wider discussion of other rare testicular tumours. Leydig cell tumours, epidermoid cysts, mature benign teratomas and testicular lymphomas are the most frequent. Leiomyomas, metastatic tumours and connective tissue tumours are exceptional. Sertoli cell tumours are rare and are similar to Leydig cell tumours in that they raise problems concerning their possible endocrine activity and the evaluation of their malignant potential. The general therapeutic rule of radical orchidectomy for any testicular tumour is still valid.     

Successful management of laryngotracheosophageal cleft through an anterior approach

Laryngotracheoesophageal cleft is an uncommon disease that is difficult to diagnose and treat. Repair of the cleft depends on length and localization of the defect as well as the associated anomalies. A successful repair of a type II cleft is reported in this paper. An anterior split of the larynx and trachea was used and provided excellent exposure and safe repair without injury to the neurovascular structures. This is the best approach and should be used to correct all type II defects.     

Neutralization Susceptibility of B Subtype Variant B' Primary HIV-1 Isolates

Susceptibility to autologous and heterologous neutralization of primary human immunodeficiency virus (HIV)-1 isolates belonging to subtype B, to the B'-variant of subtype B or to subtype F from infected individuals residing in Rio de Janeiro was assayed. A lower infectivity of the B'- and F isolates when compared to the classical B-subtype HIV-1 isolates was observed. Comparisons of neutralization susceptibilities were carried out for 19 B-subtype, 11 B'-variant and two F-subtype HIV-1 isolates with plasma from autologous and heterologous samples. Frequency of autologous neutralization was slightly lower for B-subtype isolates in comparison to B'-variant isolates. Heterologous intra-subtype neutralization was significantly lower for B-subtype than for the B'-variant or the F-subtype isolates. While B-subtype isolates were neutralized by most anti-F-subtype plasma, F-subtype isolates, although most susceptible to F-subtype antibodies, were highly susceptible to neutralization by anti-B-subtype antibodies. Cross-neutralization for B'-variant and B-subtype isolates was not as extensive as observed for B- and F-subtype isolates. However, the results presented indicate a quite extensive cross-neutralization between Brazilian HIV-1 isolates.     

Duplication of the right atrioventricular orifice in a patient with common atrium and mitral cleft

The following case involved duplication of the right atrioventricular valve in a patient with a common atrium. The accessory orifice, formed by two fine leaflets, connected the right atrium with the right ventricular outflow tract and had no subvalvular apparatus. Successful surgical correction was accomplished under standard cardiopulmonary bypass.
