The late-presenting HIV-infected patient 30 years after the introduction of HIV testing: spectrum of opportunistic diseases and missed opportunities for early diagnosis.

OBJECTIVES: The aim of the study was to describe the characteristics of HIV-infected late presenters, opportunistic diseases at diagnosis and missed opportunities to diagnose HIV infection earlier. METHODS: In a retrospective cohort study, we reviewed the medical records of all adults with newly diagnosed HIV infection admitted to the Department of Infectious Diseases of the Vivantes Auguste-Viktoria Hospital, Berlin, Germany. RESULTS: In the 5-year period from 2009 to 2013, 270 late presenters were identified. The most common AIDS-defining conditions were oesophageal candidiasis (n = 136; 51%), wasting syndrome (n = 106; 40%) and pneumocystis pneumonia (n = 91; 34%). Fifty-five patients (21%) had presented with at least one HIV indicator condition on prior contact with health care services without being offered testing for HIV. Female patients and heterosexual men [not men who have sex with men ('non-MSM')] had a significantly higher chance of being among patients previously presenting with indicator conditions and not being tested [odds ratio (OR) 4.7; 95% confidence interval (CI) 2.2-10.0; P < 0.001; and OR 2.4; 95% CI 1.2-5.1; P < 0.01, respectively]. The most commonly missed indicator conditions were leucocytopenia (n = 13; 24%), thrombocytopenia (n = 12; 22%), oral candidiasis (n = 9; 16%), unexplained weight loss (n = 7; 13%), herpes zoster (n = 5; 9%) and cervical dysplasia/cancer (n = 4; 20% of women). The median time between presentation with an indicator condition and the diagnosis of HIV infection was 158.5 days [interquartile range (IQR) 40-572 days]. Patients with oral candidiasis and unexplained weight loss had the shortest time between the "missed opportunity" and the diagnosis of HIV infection. Fifty-five hospital admissions with a total cost of over EUR 500 000 and - most importantly - six in-hospital deaths might have been prevented if HIV testing had been performed in patients with documented indicator conditions. CONCLUSIONS: Indicator conditions are still missed by clinicians. Women and 'non-MSM' are at highest risk of presenting with an indicator condition but not being tested for HIV infection.

Quality improvement in acute stroke: the New York State Stroke Center Designation Project.

BACKGROUND: Many hospitals lack the infrastructure required to treat patients with acute stroke. The Brain Attack Coalition (BAC) published guidelines for the establishment of primary stroke centers. OBJECTIVE: To determine if stroke center designation and selective triage of acute stroke patients improve quality of care. METHODS: Baseline chart abstraction was performed on all stroke patients admitted to 32 hospitals serving Brooklyn and Queens, NY, from March to May 2002. Hospitals were invited to meet BAC guideline-based criteria. Adherence was verified by on-site visits. After designation, acute stroke patients were selectively triaged. Remeasurement data were collected from August to October 2003. RESULTS: The authors abstracted 1,598 charts at baseline and 1,442 charts at remeasurement. From baseline to remeasurement, median times decreased for door to physician contact (25 vs 15 minutes, p = 0.001), CT performance for potential tissue plasminogen activator (t-PA) candidates (68 vs 32 minutes, p < 0.001), and t-PA administration (109 vs 98 minutes (p = NS). IV t-PA utilization increased from 2.4 to 5.2% (p < 0.005), select t-PA protocol violations decreased from 11.1 to 7.9% (p = NS), and the stroke unit admission rate increased from 16 to 39% (p < 0.001). In stroke centers (n = 14) vs nondesignated hospitals (n = 18), there were shorter median times from door to physician contact (10 vs 25 minutes, p < 0.001), CT performance for potential t-PA candidates (31 vs 40 minutes, p = NS), and t-PA administration (95 vs 115 minutes, p < 0.05). Stroke centers, compared with nondesignated centers, admitted acute stroke patients to stroke units more often (55.9 vs 10.9%, p < 0.001). CONCLUSIONS: Stroke center designation and selective triage of acute stroke patients improved the quality of care, including access to timely thrombolytic therapy and stroke units.

Electromagnetic stimulation as a treatment of tinnitus: a pilot study.

This paper reports the results of a study to determine whether pulsed electromagnetic stimulation, applied over the mastoid bone, caused an improvement in the level of tinnitus in long-standing tinnitus sufferers. Fifty-eight patients from the Liverpool Tinnitus Association volunteered to take part in a double-blind placebo controlled trial. Active and placebo devices were randomly allocated to these patients on their first visit. At the end of one week of treatment, each patient noted whether their tinnitus had completely disappeared, was improved, unchanged or made worse by the treatment Forty-five per cent of the patients who completed the trial were improved by the active device, but only 9% by placebo (P = 0.0013, Mann-Whitney test). We suggest that electromagnetic stimulation may be an effective treatment in some tinnitus sufferers.
