Mitral valvular prolapse (MVP) in dogs is characterized by myxomatous valvular degeneration, which is caused by abnormal valvular thickening and incomplete coaptation of the mitral valve leading to mitral regurgitation. Mitral regurgitation causes left atrial and left ventricular enlargement. Pathogenesis of the disease is unknown, although some studies have suggested the involvement of endothelin and systemic connective tissue diseases. Mitral valvular prolapse in dogs commonly occurs in aged small dog breeds, including Malteses and Shih Zhus. This case study investigated the clinical features of an affected Maltese family and performed pedigree analysis. To the best of the authors' knowledge, this is the first report of putative familial mitral valve prolapse and regurgitation in Maltese dogs. All family members in this study showed degenerative valvular changes and echocardiographic features of mitral valvular prolapse. Although disease progression differed, all dogs progressed to advanced heart failure stage within 2-3 years after diagnosis. Therefore, this is the first study to identify putative familial mitral valve prolapse in Maltese dogs. This finding suggests strong genetic etiology involved in the development of degenerative mitral valve disease in Maltese dogs. Furthermore, this finding could be a valuable resource for the identification of gene mutations in dogs with familial mitral valvular prolapse.

Acute basilar artery (BA) occlusion is a key etiology of devastating posterior circulation stroke, unless recanalization is performed early. Recanalization therapy is determined synthetically based on symptom onset time, stroke severity, and brain imaging. Herein, we report the case of a 72-year-old male patient presenting with minor neurological symptoms, but with thrombotic occlusion at the BA tip. Transcranial Doppler (TCD) showed systolic flow reversal along the vertebrobasilar arteries, and the patient benefited from endovascular thrombectomy. This case highlights the critical role of TCD in identifying hemodynamic insufficiency and determining the implementation of endovascular interventions to mitigate stroke progression.

A 12-year-old female Cocker Spaniel (7.5 kg of body weight) was presented for resection of a mammary gland tumor. During surgery, the heart rate was remarkably decreased due to a second-degree type I atrioventricular block. Atropine (0.05 mg/kg) was administered to increase the heart rate. Although the heart rate was elevated, atrial bigeminy occurred and persisted until the dog fully recovered from general anesthesia. These results highlight the possibility of atrial bigeminy caused by atropine administration during anesthesia.

Hypopharyngeal mass is an uncommon condition in the aerodigestive tract. There were only a few cases have been published in the medical literature. We experienced a case of incidentally detected hypopharyngeal mass during endotracheal intubation. Hypopharyngeal mass was located at the right posterior pharyngeal wall. The hypopharyngeal mass was small and not obstruct the glottis, and endotracheal intubation was performed successfully. We have also briefly discussed symptoms, diagnosis, and related problems during general anesthesia of hypopharyngeal mass.

A key challenge of anesthesia is to provide patients with safe and optimized anesthetic management to improve prognosis and minimize mortality and morbidity. To this end, the anesthesiologist should comprehensively understand the patient’s physical status through pre-anesthetic assessment and carefully monitor the patient during surgery. Several types of novel patient-monitoring devices may be useful to achieve this purpose. We report a case of anesthetic management in a patient with left internal carotid artery occlusion and penetrating aortic ulcer.

Objective:
Long-acting injectable (LAI) antipsychotics, such as paliperidone palmitate (PP), are known to improve treatment adherence in patients with schizophrenia, which can lead to reductions in relapse and hospitalization rates. However, relatively few studies have demonstrated the economic impact of LAIs, especially in Asian populations.
Methods:
We conducted a claim-based mirror-image study to explore changes in healthcare utilization and associated costs, among 1,272 South Korean patients with schizophrenia (ICD-10-CM code F20), between the 1-year periods before and after the initiation of PP treatment.
Results:
Patients accessed outpatient services more frequently after versus before starting PP treatment, with the number of prescription days increasing by 133.45 (p < 0.0001) and the associated costs increasing by USD 1,497.15 (p < 0.0001). The number of admission days was reduced by 11.33 after starting PP treatment (p < 0.0001) and the associated costs were reduced by USD 1,220.75 (p < 0.0001). However, admission cost savings were different according to patients’ oral drug compliance. The daily dosages for benztropine, procyclidine, and propranolol decreased, showing that there were fewer side-effects after PP-treatment (p < 0.0001).
Conclusion
Although the high acquisition cost of PP has been regarded as an obstacle to its clinical use, our results imply that the high prescription costs for PP may be counterbalanced by the reduced admission costs associated with its use. Economic outcomes for patients treated with LAIs should be investigated further to help healthcare decision-makers and providers to determine the value of LAIs relative to other treatment medications.

BACKGROUND:
The interferon-gamma (IFN-γ) releasing assay (IGRA) is widely used for latent tuberculosis infection (LTBI) diagnosis. We evaluated the analytical performance of a new automated chemiluminescent immunoanalyzer-based IGRA (CLIA-IGRA), AdvanSure I3 (LG Life Sciences, Seoul, Korea) and compared it with that of the QuantiFERON-TB Gold In-Tube (QFT-GIT) assay.
METHODS:
Repeatability and reproducibility were evaluated at four levels. Detection capability, including limit of blank (LoB), limit of detection (LoD), and limit of quantification (LoQ), was evaluated using IFN-γ standard material (National Institute for Biological Standards and Control code: 87/586). Agreement between the results of two assays was evaluated using 341 blood samples from healthcare workers and patients at a tertiary care hospital. To determine the cut-off value of CLIA-IGRA for diagnosing LTBI, the ROC curve was analyzed.
RESULTS:
Repeatability and reproducibility were 4.86–7.00% and 6.36–7.88% CV, respectively. LoB, LoD, and LoQ were 0.022, 0.077, and 0.249 IU/mL, respectively. IFN-γ values between CLIA-IGRA and QFT-GIT showed a strong correlation within the analytical measurable range of both assays, especially when the value was low. Qualitative comparison of the two assays yielded a 99.1% overall agreement (kappa coefficient=0.98). A cut-off value of 0.35 IU/mL was appropriate for diagnosing LTBI.
CONCLUSIONS
CLIA-IGRA is a reliable assay for LTBI diagnosis, with performance similar to that of QFT-GIT.

Brain abscess, a life-threatening infection, can result from hematogenous spread. Although uncommon, Klebsiella pneumoniae can lead to brain abscess and systemic dissemination. In this case report, Klebsiella pneumoniae brain abscess, linked with prostate abscess, in a 57-year-old diabetic male with liver cirrhosis and hepatitis B, resulted in fatal sepsis despite antibiotic therapy. This case underscores Klebsiella's grave risk in immunocompromised patients, highlighting brain abscess and high mortality. Early diagnosis, treatment, and evaluation for multiple organ involvement are crucial.
