Background: Electrocardiography is a very useful diagnostic tool. However, errors in placement of ECG leads can create artifacts, mimic pathologies, and hinder proper ECG interpretation. This is the second of a two-part series discussing how to recognize and avoid these errors. Methods: 12-lead ECGs were recorded in a single male healthy subject in his mid 20s. Various precordial lead misplacements were compared to ECG recordings from correct lead placement. Results: Precordial misplacements caused classical changes in ECG patterns. Techniques of differentiating these ECG patterns from true pathological findings were described. Conclusion: As in Part I of this series, recognition and interpretation of common ECG placement errors is critical in providing optimal patient care.

Gomez and her colleagues have presented a helpful study of the relationship of the chaplains in her health system to physicians which highlights several barriers to a well-integrated relationship and thus to more optimal patient care. We have seen these same barriers as we have consulted with health systems nationally and have also identified many best practices that mediate or even eliminate many of these barriers. This commentary describes some of what we have seen as chaplain-generated causes of those barriers and effective strategies that have been employed to overcome them. We also provide some resources for chaplains who wish to institute some of these best practices themselves.

Optimal Patient Care

Physician trainees working in a pediatric intensive care unit (ICU) were interviewed early in their training experience, at the end of their training, and 1 to 12 months after their training had ended. Pediatricians responded significantly differently from anesthesiologists: they commented more often about their own feelings, and less often about procedural-intellectual-technical matters as contrasted with feelings and relationships. Pediatricians were also more likely than anesthesiologists to mention their own emotional reactions to ill children, their sense that patient death meant physician failure, and their dismay early in the training period about the stressful intensity of the work. Physicians who were parents differed from those who were not parents by commenting more frequently about their work with the parents of patients, and about the necessity for teamwork. Physician trainees interviewed early in the training period were less reflective about the experience, and less likely to comment on feelings and relationships, compared to those interviewed later. Analysis of the sources of satisfaction and discontent with work in the ICU, as stated by the physician trainees, has been useful in efforts to improve the climate of work and learning in the unit, and to provide optimal patient care.

Bacteria Identification

OBJECTIVE: To comparatively detect A. actinomycetemcomitans and F. nucleatum from periodontal and healthy sites. METHODS: Subgingival clinical samples from 50 periodontitis adult patients and 50 healthy subjects were analyzed. Both organisms were isolated using a trypticase soy agar-bacitracin-vancomycin (TSBV) medium and detected by PCR. Conventional biochemical tests were used for bacteria identification. RESULTS: A. actinomycetemcomitans and F. nucleatum were isolated in 18% and 20% of the patients, respectively, and in 2% and 24% of healthy subjects. Among A. actinomycetemcomitans isolates, biotype II was the most prevalent. Primer pair AA was 100% sensitive in the detection of A. actinomycetemcomitans from both subject groups. Primers ASH and FU were also 100% sensitive to detect this organism in healthy subject samples. Primer pair FN5047 was more sensitive to detect F. nucleatum in patients or in healthy samples than primer 5059S. Primers ASH and 5059S were more specific in the detection of A. actinomycetemcomitans and F. nucleatum, respectively, in patients and in healthy subject samples. CONCLUSIONS: PCR is an effective tool for detecting periodontal pathogens in subgingival samples, providing a faster and safer diagnostic tool of periodontal diseases. The method's sensitivity and specificity is conditioned by the choice of the set of primers used.

AbstractEquivalent results between different laboratories enable optimal patient care and can be achieved with harmonisation. We report on EQA-initiated national harmonisation of seven enzymes using commutable samples.EQA samples were prepared from human serum spiked with human recombinant enzymes. Target values were assigned with the IFCC Reference Measurement Procedures. The same samples were included at four occasions in the EQA programmes of 2012 and 2013. Laboratories were encouraged to report IFCC traceable results. A parallel study was done to confirm commutability of the samples.Of the 223 participating laboratories, 95% reported IFCC traceable results, ranging from 98% (ASAT) to 87% (amylase). Users of Roche and Siemens (97%) more frequently reported in IFCC traceable results than users of Abbott (91%), Beckman (90%), and Olympus (87%). The success of harmonisation, expressed as the recovery of assigned values and the inter-laboratory CV was: ALAT (recovery 100%; inter-lab CV 4%), ASAT (102%; 4%), LD (98%; 3%), CK (101%; 5%), GGT (98%; 4%), AP (96%; 6%), amylase (99%; 4%). There were no significant differences between the manufacturers. Commutability was demonstrated in the parallel study. Equal results in the same sample in the 2012 and 2013 EQA programmes demonstrated stability of the samples.The EQA-initiated national harmonisation of seven enzymes, using stable, commutable human serum samples, spiked with human recombinant enzymes, and targeted with the IFCC Reference Measurement Procedures, was successful in terms of implementation of IFCC traceable results (95%), recovery of the target (99%), and inter-laboratory CV (4%).

Proper Interpretation

This chapter examines the fundamental neurophysiological principles involved in determining electroencephalographic (EEG) artifact and provides general instructions for minimizing the risk of error during clinical interpretation. Examples from EEG recordings are given to illustrate common artifacts that may be challenging to the reader because they mimic epileptiform pattern associated to people with epilepsy. Emerging techniques used to detect and reduce artifact without altering the electrocerebral signal are being developed to limit the contamination. While many artifacts are easy to recognize, more complex waveforms may confuse even the most experienced reader. Constant vigilance and a team effort to minimize artifact will help to ensure a proper interpretation of the EEG for optimal patient care.

This chapter examines the roles of biosafety and quality assurance (with emphasis on the importance of external quality assessment) and demonstrates their importance in a clinical mycology laboratory setting. Their practice and combination are required to ensure the provision of precise and accurate analyses in a safety-focused environment to support optimal patient care.
