Purpose: To examine the relation between uveitis and common variable immunodeficiency (CVID).
Methods: Retrospective analysis of patients included in the French DEFI cohort of adults with CVID and of ...patients identified by reviewing the literature.
Results: Four patients were identified in the DEFI study (frequency of uveitis: 1.6%). The course of uveitis was not changed in the patients who started intravenous immunoglobulins replacement therapy after CVID diagnosis. Ten cases of CVID-associated uveitis were listed in the literature. Overall, among the 14 patients, uveitis was always chronic, usually bilateral (n = 11) and granulomatous (n = 9). Seven patients presented with a "sarcoid-likeâ syndrome. Nine patients had granulomatous uveitis suggestive of ocular sarcoidosis. Five patients were treated with local corticosteroids, and 9 required systemic treatment (corticosteroids alone n = 5 and/or immunosuppressive agents n = 4).
Conclusions: CVID can be associated with uveitis. Since uveitis can reveal the immunodeficiency, CVID diagnosis should be considered at the time of uveitis diagnosis.
Rhinoscopy was performed on 10 dogs with sinonasal aspergillosis (SNA). Direct access to the sinus via the nasal ostium was possible with a flexible endoscope to allow sinuscopy. Debridement of ...fungal plaques in the frontal sinus and the nasal cavity was performed, and a sinus and nasal deposition therapy with clotrimazole (1%) cream was made under rhinoscopic guidance. No oral medication was administered following the procedure. A rhinoscopic follow-up was performed monthly until cure. Six of ten (60%) dogs presented fungal plaques in the nasal cavity and in the frontal sinus and 4/10 (40%) dogs presented fungal plaques only in the frontal sinus. Five of ten (50%) dogs were considered to be cured at the first follow-up rhinoscopy, 4/10 (40%) after the second follow-up, and 1/10 (10%) after the third. Two dogs had delayed recurrence of SNA rhinoscopically assessed 12 and 21 mo, respectively, after the last clotrimazole treatment. Endoscopic debridement of fungal plaques and clotrimazole (1%) cream deposition therapy seems to be a valuable minimally invasive technique for SNA treatment in dogs without the use of complementary oral medication. Delayed recurrence is a potential finding following treatment of SNA.
This article proposes a theory whereby the physiological changes induced by placebos are accompanied by corresponding changes in the patients mental state. The author begin by defining the placebo ...problem, and review the three leading theoretical approaches for solving it meaning theory, expectancy theory, and conditioning theory before discussing the significant theoretical issue posed by a classic case of placebo immunosuppression in rats. The theory of full correspondence is then introduced as a way of explaining the nature of the placebo effect and of resolving the conflict between meaning-oriented and mechanism-oriented approaches to the phenomenon. After proposing how to test the theory experimentally and examining existing evidence for it. The author consider its ability to integrate the dominant theoretical perspectives of the placebo effect within a framework centered on the patient's subjective experience, the one variable overlooked on both sides of the meaning/mechanism divide.
Cancer is the leading cause of death in dogs, yet there are no established screening paradigms for early detection. Liquid biopsy methods that interrogate cancer-derived genomic alterations in ...cell-free DNA in blood are being adopted for multi-cancer early detection in human medicine and are now available for veterinary use. The CANcer Detection in Dogs (CANDiD) study is an international, multi-center clinical study designed to validate the performance of a novel multi-cancer early detection "liquid biopsy" test developed for noninvasive detection and characterization of cancer in dogs using next-generation sequencing (NGS) of blood-derived DNA; study results are reported here. In total, 1,358 cancer-diagnosed and presumably cancer-free dogs were enrolled in the study, representing the range of breeds, weights, ages, and cancer types seen in routine clinical practice; 1,100 subjects met inclusion criteria for analysis and were used in the validation of the test. Overall, the liquid biopsy test demonstrated a 54.7% (95% CI: 49.3-60.0%) sensitivity and a 98.5% (95% CI: 97.0-99.3%) specificity. For three of the most aggressive canine cancers (lymphoma, hemangiosarcoma, osteosarcoma), the detection rate was 85.4% (95% CI: 78.4-90.9%); and for eight of the most common canine cancers (lymphoma, hemangiosarcoma, osteosarcoma, soft tissue sarcoma, mast cell tumor, mammary gland carcinoma, anal sac adenocarcinoma, malignant melanoma), the detection rate was 61.9% (95% CI: 55.3-68.1%). The test detected cancer signal in patients representing 30 distinct cancer types and provided a Cancer Signal Origin prediction for a subset of patients with hematological malignancies. Furthermore, the test accurately detected cancer signal in four presumably cancer-free subjects before the onset of clinical signs, further supporting the utility of liquid biopsy as an early detection test. Taken together, these findings demonstrate that NGS-based liquid biopsy can offer a novel option for noninvasive multi-cancer detection in dogs.

The renewed interest in the use of fluorochromes for malaria diagnosis prompted us to evaluate the acridine orange fluorescence technique on blood slides, and to compare it with established ...techniques using thick and thin blood films and the QBC
™ malaria test, using the Giemsa-stained thick film technique as our standard method for comparison. We compared 123 positively diagnosed cases and 120 negative cases. For primary samples (day 0), the sensitivity of the thin blood film fluorescence acridine orange technique (AO) was 96·4%, and its specificity was 95·1%. In cases of imported malaria, with a prevalence rate of 16·2%, the positive predictive value was 79·2% and the negative predictive value 99·3%. Sensitivity of AO was significantly higher than that of Giemsa-stained thin blood films for parasitaemias <5000/μL. The potential of AO for species diagnosis of
Plasmodium was 85·2%, using Giemsa-stained thin films as the reference technique. Where QBC
™ imposes a cost limitation, especially in developing countries, despite its high performance, the AO diagnostic technique is a valuable alternative, because of its simplicity, almost negligible cost, and its diagnostic reliability. The method may also have potential value in the diagnosis of other microbiological diseases.
