<b><i>Objectives:</i></b> In this study, we describe ocular dirofilariasis in Bulgaria. <b><i>Materials and Methods:</i></b> We studied 7 patients with a subconjunctival or periorbital form of <i>Dirofilaria repens</i> infection during 2010–2019. Morphological, serological, and paraclinical diagnostic methods were used. <b><i>Results:</i></b> The patients (6 females, 1 male) were aged between 23 and 72 years. In 3 patients, subcutaneous nodules were detected in the area of the upper eyelid, in 1 patient the location was suborbital. In 3 other patients, a subconjunctival location was found. All patients were cured definitively by removal of the larva, without etiologic treatment. <b><i>Conclusion:</i></b> The most reliable and easily accessible diagnostic method is morphological analysis by microscopy of histological preparations of the parasite. In dirofilariasis, ocular location is the most common in humans, and it deserves special attention of clinicians.

A 59-year-old female living in Rayong Province, eastern Thailand, presented with painless, right upper eyelid nodule for 3 months. Upon removal of the eyelid mass, a well-circumscribed, firm globular mass with diameter about 1 cm was found. Histopathological examination revealed an immature female dirofilarial worm reminiscent of Dirofilaria repens, characterized by prominent sharp longitudinal ridges at external surface of the cuticle. Analysis of the mitochondrial 12S rRNA sequence showed that the worm belongs to Candidatus Dirofilaria hongkongensis. It is likely that some infections previously reported as D. repens based on histological examination may have actually been due to Candidatus D. hongkongensis.

In the statistical analysis of data, a model might be awfully fitted with the presence of outliers. Besides, it has been well established to use residuals for identification of outliers. The asymptotic properties of residuals can be utilized to contribute diagnostic tools. However, it is now evident that most of the existing diagnostic methods have failed in identifying multiple outliers. Therefore, this paper proposed a diagnostic method for the identification of multiple outliers in GLM, where traditionally used outlier detection methods are effortless as they undergo masking or swamping dilemma. Hence, an investigation was carried out to determine the capability of the proposed GSCPR method. The findings obtained from the numerical examples indicated that the performance of the proposed method was satisfactory for the identification of multiple outliers. Meanwhile, in the simulation study, two scenarios were considered to assess the validity of the proposed method. The proposed method consistently displayed higher percentage of correct detection, as well as lower rates of swamping and masking, regardless of the sample size and the contamination levels.

Propulsion diagnostic method evaluation strategy (ProDiMES) offers an aircraft engine diagnostic benchmark problem where the performance of candidate diagnostic methods is evaluated while a fair comparison can be established. In the present paper, the performance evaluation of a number of gas turbine diagnostic methods using the ProDiMES software is presented. All diagnostic methods presented here were developed at the Laboratory of Thermal Turbomachinery of the National Technical University of Athens (LTT/NTUA). Component, sensor, and actuator fault scenarios that occur in a fleet of deteriorated twin-spool turbofan engines are considered. The performance of each diagnostic method is presented through the evaluation metrics introduced in the ProDiMES software. Remarks about each methods performance as well as the detectability and classification rates of each fault scenario are made.

Ehrlichia canis is a rickettsial intracellular obligate bacterial pathogen and agent of canine monocytic ehrlichiosis. The prevalence of this disease in veterinary medicine can vary depending on the diagnostic method used and the geographic location. One hundred and fifty-two canine blood samples from six veterinary clinics and two shelters from Sinaloa State (Mexico) were analyzed in this study. All animals were suspected of having Canine Monocytic Ehrlichiosis (CME). The diagnostic methods used were the ELISA (Snap4Dx, IDEXX) together with blood smear and platelet count. From all dogs blood samples analyzed, 74.3% were positive to E. canis by ELISA and 40.1% were positive by blood smear. The sensitivity and specificity observed in the ELISA test were 78.8% and 86.7%. In addition, thrombocytopenia was presented in 87.6% of positive dogs. The predominant clinical manifestations observed were fever, anorexia, depression, lethargy, and petechiae. Consequently, this is the first report in which the morulae were visualized in the blood samples, and E. canis-specific antibodies were detected in dogs from Sinaloa, Northwest of Mexico.

Neurological deficits associated with cerebrovascular disease such as aphasia, dementia, anosognosia and aprosodia may impair the ability to express or experience depressive symptoms. Identification of depression in the absence of verbal report on subjective mood state is a difficult task. The value of various diagnostic methods including depressive rating scales, standard psychiatric interviews and biological variables in the diagnosis of depression in cerebrovascular disease is considered. This review concludes by focusing on the deficiencies of existing approaches in the diagnostic assessment of depression in patients with severe communication and comprehension deficits and emphasizes the importance of devising a standard diagnostic method with less reliance on verbal responses.

Background: We reviewed the literatures focusing on trichogram and comparing it with other newly introduced trichologic diagnostic methods (to be specific trichoscopy). Methods: This is a narrative review. We searched PubMed, Scopus, EMBASE and the Web of Science for most relevant and English publications using the terms ‘trichogram’ or ‘phototrichogram’ or ‘trichoscan’ or ‘unit area trichogram’ or ‘trichoscopy’.The results were then screened by two independent reviewers and discrepancies was reviewed by another author. The text and data related to these terms were then selected out of each included study and discussed with all authors for inclusion in this study. Results: There are many hair disorders with diagnostic clues of trichogram such as Alopecia areata, Androgenic alopecia, Anagen effluvium, Telogen effluvium, Trichotillomania, Pemghigus, Psoriasis, and Loose anagen syndrome. Trichoscopy have become a widely used non-invasive practical diagnostic tool for evaluation of many immune-mediated or non-immune mediated dermatologic disorders with involvement of hair. Trichoscopy is also commonly used for following up and evaluating the therapeutic responses in affected hair-bearing area. Conclusion: Trichogram is a valuable diagnostic method for complicated hair disorders butthe trend is toward less aggressive and more sensitive informative methods like trichoscopy and trichoscan. Key words: Trichogram, Trichoscopy, Phototrichogram, Trichoscan, Unit Area Trichogram, Dermatoscopy, Dermoscopy, Hair, Alopecia, Scalp, Diagnoses

: Rapid diagnosis in patients with acute pancreatitis is essential to optimal therapeutic outcomes. Upon clinical suspicion, various methods could be used to confirm the diagnosis based on the symptoms and examinations. Laboratory tests are an important diagnostic method in this regard based on the increased serum amylase/lipase. In this study, we described the case of a 31-year-old male patient presenting with the clinical signs of pancreatitis with normal amylase and elevated triglyceride in the follow-up. In case of strong clinical suspicion, other tests and diagnostic methods are recommended to confirm acute pancreatitis.

Due to the importance of the drive system reliability, several diagnostic methods have been investigated for the SSTPI-IM association in the literature. Based on the normalized currents and the current vector slope, this paper investigates a fuzzy diagnostic method for this association. The fuzzy logic technique is appealed in order to process the diagnosis variable symptoms and the faulty IGBT information. Indeed, the design, inputs, and rules of the fuzzy logic are distinct compared with the other existing diagnostic methods. The proposed fuzzy diagnostic method allows the best efficient detection and identification of the single and phase OCF of the SSTPI-IM association. Accordingly, after the fault detection and identification using this proposed FLC diagnostic method, a reconfiguration step of IGBT OCFs must be applied in order to compensate for these faults and ensure the drive system continuity. This reconfiguration is based on the change of the SSTPI-IM topology to the FSTPI-IM topology by activating or deactivating the used relays. Several simulation results utilizing a direct RFOC controlled SSTPI-IM drive system are investigated, showing the fuzzy diagnostic and reconfiguration methods’ performances, their robustness, and their fast fault detection during distinct operating conditions.
