Introduction: Laboratory examinations constitute a major factor in achieving the correct clinical diagnosis for patients. However, the ordering of unnecessary or inappropriate laboratory testing remains common, with consequent consumption of laboratory resources whether human or material. The present work evaluated the level of satisfaction of laboratory practitioners toward the appropriateness of laboratory tests ordered by physicians. Methods: This cross-sectional study involved a total of 256 medical laboratory practitioners representing different qualifications and health care sectors, who answered several questions concerning their knowledge and attitudes toward inappropriate laboratory testing ordered by physicians. Results: More than 85% of respondents agreed with the definition provided in the survey, which is substantially consistent with prior studies. More than 90% affirmed the associated drain on time and resources. However, discrepant responses were received concerning physician awareness of test availability, and participants reported laboratory staff arguments with physicians due to orders for unnecessary tests. Data showed that unnecessary orders were mainly requested by physicians of less experience. Conclusions: Ultimately, dissatisfaction was manifest among clinical laboratory professionals, and educational interventions are required to moderate request behaviors.

Laboratory Examinations

Percutaneous ultrasound-guided cholecystocentesis was performed on 13 healthy beagle dogs to determine whether percutaneous ultrasound-guided cholecystocentesis in the dog was a feasible and safe procedure. Clinical, laboratory and ultrasonographic examinations were done at 0 and 10 minutes, in the 2nd and 16th hour, and on the 7th day. They included a detailed physical examination of the mucous membranes, cardiorespiratory system and abdominal organs. Laboratory examinations of the blood consisted of a complete blood count, determination of packed cell volume (PCV), haemoglobin (Hb), total plasma protein (TPP), parameters of haemostasis including prothrombin time (PT), activated partial thromboplastin time (APTT), and enzyme activities reflecting hepatobiliary function, i.e. aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glutamyltransferase (GGT). Ultrasonographic findings of the gallbladder (size, shape, wall, content) and appearance of the biliary tract and the surrounding cranial intraabdominal organs were also evaluated. Percutaneous ultrasound-guided cholecystocentesis was performed easily during the study, and dogs tolerated well the procedure performed without anaesthesia. All laboratory parameters of the blood remained within normal limits throughout the study. However, some follow-up values, i.e. PCV, TPP, APTT and ALT, demonstrated statistically significant differences when compared to baseline measurements, which might reflect the effect of 24-hour fasting before the experiment, as well as day-to-day metabolic fluctuations due to feeding and water supply during the study. There were no visible signs of bleeding from the liver, bile leakage from the gallbladder or accumulation of free peritoneal fluid during repeated ultrasonographic examinations. Percutaneous ultrasound-guided cholecystocentesis seems to be an important diagnostic procedure in canine gallbladder diseases and can be used safely and easily to gain gallbladder bile for diagnosis of bacterial cholecystitis or for investigating hepatobiliary function in the dog.

This small but easily read book is a carefully documented summary of the clinical, laboratory and necropsy experience at the Presbyterian Hospital in New York City in 200 cases of systemic lupus erythematosus during a 20-year period. The disease process is presented according to manifestations in individual organs and laboratory examinations. This approach emphasizes the role of the disease as one of the "great imitators" of medicine, along with syphilis, tuberculosis and malaria. Of great value are the careful observations and long-term follow-up of these patients, which gives a genuine picture of the natural history of the disease, one of the stated aims of the author.

Medical diagnosis with the help of computational techniques is a very useful tool for doctors for the purpose of better diagnosis. In this chapter, an attempt has been made to reduce the number of tests required for diagnosis using generalized fuzzy sets for initial decision making as per the characteristics of ingested water in normal routine. The quality of water in terms of type and concentration of contaminants varies from region to region. The analogy between concentration of different contaminants in drinking water and risk analysis based on intuitionistic fuzzy sets (IFSs) have been investigated. Hypothetical data was processed in view of the finite set of heavy metals, diseases, and places to investigate the effect of selected heavy metal on the human health. The findings will not only help in diagnosis but also offer cost-cutting and ecofriendly strategy by avoiding unnecessary clinical laboratory examinations.

AbstractThe presence of microvascular invasion (MVI) is a critical determinant of early hepatocellular carcinoma (HCC) recurrence and prognosis. We developed a nomogram model integrating clinical laboratory examinations and radiological imaging results from our clinical database to predict microvascular invasion presence at preoperation in HCC patients. 242 patients with pathologically confirmed HCC at the Ningbo Medical Centre Lihuili Hospital from September 2015 to January 2021 were included in this study. Baseline clinical laboratory examinations and radiological imaging results were collected from our clinical database. LASSO regression analysis model was used to construct data dimensionality reduction and elements selection. Multivariate logistic regression analysis was performed to identify the independent risk factors associated with MVI and finally a nomogram for predicting MVI presence of HCC was established. Nomogram performance was assessed via internal validation and calibration curve statistics. Decision curve analysis (DCA) was conducted to determine the clinical usefulness of the nomogram model by quantifying the net benefits along with the increase in threshold probabilities. Survival analysis indicated that the probability of overall survival (OS) and recurrence-free survival (RFS) were significantly different between patients with MVI and without MVI (P < 0.05). Histopathologically identified MVI was found in 117 of 242 patients (48.3%). The preoperative factors associated with MVI were large tumor diameter (OR = 1.271, 95%CI: 1.137–1.420, P < 0.001), AFP level greater than 20 ng/mL (20–400 vs. ≤ 20, OR = 2.025, 95%CI: 1.056–3.885, P = 0.034; > 400 vs. ≤ 20, OR = 3.281, 95%CI: 1.661–6.480, P = 0.001), total bilirubin level greater than 23 umol/l (OR = 2.247, 95%CI: 1.037–4.868, P = 0.040). Incorporating tumor diameter, AFP and TB, the nomogram achieved a better concordance index of 0.725 (95%CI: 0.661–0.788) in predicting MVI presence. Nomogram analysis showed that the total factor score ranged from 0 to 160, and the corresponding risk rate ranged from 0.20 to 0.90. The DCA showed that if the threshold probability was > 5%, using the nomogram to diagnose MVI could acquire much more benefit. And the net benefit of the nomogram model was higher than single variable within 0.3–0.8 of threshold probability. In summary, the presence of MVI is an independent prognostic risk factor for RFS. The nomogram detailed here can preoperatively predict MVI presence in HCC patients. Using the nomogram model may constitute a usefully clinical tool to guide a rational and personalized subsequent therapeutic choice.
