Histological evidence of pancreatitis is commonly found in necropsy studies in cats. A clinical diagnosis of pancreatitis is challenging due to nonspecific clinical signs, a lack of diagnostic lipase cutoffs, and frequent presence of multiple diseases. It is still unknown how often pancreatitis alone is found in sick cats and how often clinicopathological evidence of pancreatitis in sick cats does not lead to a clinical diagnosis of pancreatitis. Our aims were to evaluate the extent of comorbidities in cats with suspected pancreatitis, evaluate how often sick cats with hyperlipasemia are diagnosed only with non-pancreatic diseases, and compare their clinical findings. Medical records of 563 client-owned hospitalized cats with available lipase activity measurement (LIPC Roche) > 30 U/L (RI, 6-26) were searched and medical diagnoses recorded and grouped by organ system. Clinicopathological findings were compared between cats with pancreatitis alone (PA), pancreatitis with concurrent disease (PD), and no suspected pancreatitis (NP). We found that PA was present in 33 (6%) cats, 159 cats (28%) were in the PD group, and 371 cats (66%) had no suspected pancreatitis (NP). Clinical, laboratory, and ultrasonographic findings did not differ between PA and PD cats. Lipase activities did not differ between the three groups. The most common disease categories in PD and NP cats were gastrointestinal, hepatobiliary, renal/urinary, and endocrine, and renal/urinary, gastrointestinal, cardiac, and musculoskeletal, respectively. We conclude that cats are rarely hospitalized because of suspected pancreatitis alone, and PA cats did not differ clinically from PD cats. Hyperlipasemia in sick cats without a diagnosis of pancreatitis may be due to a reactive pancreatopathy or preexisting chronic pancreatitis.

Background: Benign paroxysmal positional vertigo (BPPV) is characterized by brief, intense episodes of vertigo triggered by abrupt changes in head position. It is generally accepted as being most common in adults, while it is regarded as rare in children. It is necessary to compare the disease between pediatric and adult patients for a better understanding of the disease\'s characteristics and its natural history. This study aimed to identify the clinical characteristics of BPPV in children and compare them with those of adult BPPV patients. Methods: All children ≤ 18 years old who were diagnosed with BPPV were selected by searching the electronic database of our hospital. Clinical features were identified by medical record review. For adult patients, we collected data from patients > 19 years of age. Results: A total of 30 pediatric (13.65 ± 4.15 years old) and 264 adult patients (60.86 ± 13.74 years old) were included in the study. Among pediatric patients, the lateral canals were involved in 80% and the posterior canals in 16.67%. In adult patients, the lateral and posterior canals were involved similarly (p = 0.007). The degree of nystagmus in pediatric patients was 6.82 ± 12.09, while in adults it was 15.58 ± 20.90 (p < 0.001). The concurrent dizziness disorder was higher in the pediatric group and recurrence was higher in the adult group. In the regression analysis, it was found that adult patients had a stronger nystagmus with a value of 6.206 deg/sec, and the risk of concurrent dizziness disorder was found to be 5.413 times higher in the pediatric group (p < 0.05). Conclusions: BPPV occurs in pediatric patients with lower prevalence, but it cannot be overlooked. In the pediatric group, a relatively high proportion of patients demonstrated lateral canal involvement, weaker nystagmus, and additional dizziness disorder.

Anti-glomerular basement membrane (GBM) disease is a rapidly progressive glomerulonephritis which, in some instances, occurs concurrently with other diseases such as antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. Rarely, it also occurs with membranous nephropathy (MN). We report a series of such patients, characterizing their long-term follow up.
Case series.
Twelve patients referred to 1 medical center between 2001 and 2019 with anti-GBM disease and MN whose clinical characteristics and course were described.
Patients\' ages ranged from 20 to 81 years old, and all presented with severe acute kidney injury requiring dialysis on presentation or shortly thereafter. Only 1 patient had pulmonary findings on presentation. The predominant pathology was crescentic and necrotizing glomerulonephritis with linear staining for immunoglobulin G along the GBM associated with epimembranous electron-dense immune-type deposits. All 11 patients who were tested had significant titers of anti-GBM antibodies, but only 1 of the 5 tested for phospholipase A2 receptor (PLA2R) on biopsy was positive. Eight patients received therapy with cyclophosphamide, prednisone, and plasmapheresis; 2 patients with prednisone and plasmapheresis; and 2 with rituximab-based regimens. Progression to a requirement for kidney replacement therapy occurred in all 12 patients, but 2 patients later recovered kidney function. Recurrence of anti-GBM disease did not occur for any of the patients studied.
Incomplete testing for PLA2R in biopsy and serum, limited sample size, and lack of uniform treatment regimen.
In this case series, the presentation of concurrent anti-GBM disease and MN was characterized by rapidly progressive glomerulonephritis and poor kidney outcomes. These findings suggest possible value from earlier diagnosis and the need for identification of more effective treatment regimens.

Multimorbidity is a global health challenge. Here, we define multimorbidity, describe ways multimorbidity is measured, discuss the prevalence of multimorbidity and how it differs across different populations, examine mechanisms of disease and disability, and discuss the effects of multimorbidity on outcomes such as survival and function.
