The proportion of cat cats among companion animals has been increasing at an average annual rate of 25.4% since 2012. Cats have strong wildness compared to dogs, so they have a characteristic of hiding diseases well. Therefore, when the guardian finds out that the cat has a disease, the disease may have already worsened. Symptoms such as anorexia (eating avoidance), vomiting, diarrhea, polydipsia, and polyuria in cats are some of the symptoms that appear in cat diseases such as diabetes, hyperthyroidism, renal failure, and panleukopenia. It will be of great help in treating the cat's disease if the owner can recognize the cat's polydipsia (drinking a lot of water), polyuria (a large amount of urine), and frequent urination (urinating frequently) more quickly. In this paper, 1) Efficient version of DeepLabCut for posture prediction running on an artificial intelligence server, 2) yolov4 for object detection, and 3) LSTM are used for behavior prediction. Using artificial intelligence technology, it predicts the cat's next, polyuria and frequency of urination through the analysis of the cat's behavior pattern from the home CCTV video and the weight sensor of the water bowl. And, through analysis of cat behavior patterns, we propose an application that reports disease prediction and abnormal behavior to the guardian and delivers it to the guardian's mobile and the main server system.

A ten-year-old holstein cow was presented because of prolapse of the third eyelid and apparent hyperplasia of the right lower eyelid. Historical findings included increased appetite as well as polyuria and polydipsia for about two weeks. The most remarkable fadings on physical examination were a large periocular proliferative tissue and bleeding. Surgical incision was used both as a biopsy and therapeutic tool in holstein cow with mass. Histopathological examination of the mass revealed squamous cell carcinoma. Blood and milk tests of patient with squamous cell carcinomatosis were peformed, but normal values.

Hyponatremia which is due to excessive sodium loss in the urine and decrease in extracellular fluid volume following an acute or chronic central nervous system injury, has been conjunctively described as cerebral salt wasting syndrome (CSWS). This syndrome is often confused with dilutional hyponatremia due to inappropriate secretion of antidiuretic hormone. Accurate diagnosis and management are mandatory for improvement of the course of the disease. This report describes a case of a 31-year-old male patient with CSWS associated with tuberculous meningitis. The patient exhibited hyponatremia, polyuria, excessive natriuresis, volume depletion, and hypotension. He was diagnosed to manifest CSWS and was treated by administration of fluids, salt, and fludrocortisone. After the respective treatments, symptoms of polyuria and hypotension were gradually resolved and hyponatremia was corrected.

A 3-year-old boy with a Wilms' tumor had unusually severe hypertension, polydipsia, polyuria and hypokalemia. Physical examination on admission was unremarkable except for the presence of a smooth, firm mass in the right abdomen. Computerized tomography showed a tumor occupying the upper two thirds of the right kidney. Plasma renin activity and aldosterone concentration were markedly elevated, 37.7 mg/ml/hour(normal in supine position 0.15-2.33 mg/ml/hour) and 120.1 ng/dL(normal in supine position 1 to 16 ng/dL), respectively. Hypertension varied from 150/90 mmHg to 240/180 mmHg, and was not effectively controlled by antihypertensive drugs. Right nephrectomy was performed on the sixth hospital day. At laparatomy, there was no evidence of mechenical compression of the renal artery by the tumor. The tumor, about 8 cm in diameter, was confined to the renal capsule without involvement of the renal blood vessels at the hilum. Histopathology was Wilms' tumor of favorable histology. On electron microscopy, tumor cells contained intracytoplasmic electron dense secreting graules, suggesting the possibility of renin secreting tumor cells. Shortly after nephrectomy, signs and symptoms were relieved dramatically, and plasma renin activity and aldosterone concentration were also decreased to normal.

Central diabetes insipidus (DI) is a syndrome characterized by thirst, polydipsia and polyuria. Langerhans cell histiocytosis is one of the etiologies of DI. Recently we experienced a central DI associated with Langerhans cell histiocytosis. The 44 years old female patient complained right hip pain, polydipsia and polyuria. We carried out water deprivation test. After vasopressin injection, urine osmotic pressure was increased from 109 mOsmol/kg to 327 mOsmol/kg (300%). Brain MRI showed a thickened pituitary stalk and air bubble like lesions sized with 5cm, 7cm was shown on fifth L-spine and right hip bone at hip bone CT. CT guided biopsy revealed abnormal histiocytes proliferation and abundant lymphocytes. The final diagnosis was central DI associated with systemic Langerhans cell histiocytosis invading hip bone, L-spine and pituitary stalk. Desmopressin and etoposide chemotherapy were performed to the patient.

A 10-year-old, spayed female miniature schnauzer was referred to the Veterinary Medical Teaching Hospital of Chungnam National University due to evaluation of sudden polyuria (PU) and, polydipsia (PD) (540 mL/kg/day) with severe anemia and weight loss. Blood examination results were normal except for severe anemia (hematocrit, [HCT]: 11.8%). Urinalysis revealed a urine specific gravity (USG) of 1.003, whereas urine sediment was not specific. Urine osmolality was 90 mOsm (reference range: 800~2500 mOsm), and plasma osmolality was 303 mOsm. No specific lesions were found using diagnostic imaging including radiography, ultrasonography and magnetic resonance imaging (MRI). The serum cortisol level was normal in cosyntropin stimulation test. Plasma arginine vasopressin (AVP) concentration was <0.4 pg/mL (reference range: 3.49~5.45 pg/mL). Blood transfusion was initiated in addition to an oral prescription of desmopressin acetate (DDAVP, 0.1 mg/head) thrice a day for one week. The patient was rechecked for clinical signs, urine osmolality, and USG; the clinical signs of PU/PD were resolved, urine osmolality increased to 1106 mOsm, and, USG increased to 1.021. Considering the improved clinical signs, and increased urine osmolality, and USG after DDAVP treatment, the dog was diagnosed with central diabetes insipidus. USG and urine osmolality increased to >1.030 and 2200 mOsm, respectively. Anemia also gradually improved and HCT increased to >37%. DDAVP was tapered to 0.1 mg/head twice a day and all clinical signs in the patient have completely resolved.

Amitraz is used as farm-animal insecticide. Its side effects in humans are related to its pharmacological activity on alpha 2-adrenergic receptors. The case describes a previously healthy 46-year-old woman who intentionally ingested approximately 250mL of liquid amitraz. She presented with vomiting, altered mental status, miosis, dry mouth, hypopnea, metabolic and respiratory acidosis, hypotension, hypothermia, polyuria, metabolic acidosis, elevated serum aminotransferase and abdominal distension. Supportive treatments including mechanical ventilation, hydration, dopamine infusion, bicarbonate infusion and gastric decompression resulted in improvement. By hospital day 3, she recovered with resolution of abdominal distension. It is paramount to recognize amitraz poisoning when a pesticide-intoxicated patient presets with signs and symptoms consistent with organophosphate intoxicated patients but with greater alpha 2-adrenergic related symptoms such as decreased bowel motility and xerostomia.

A ten-year-old, male cat presented with recent loss of body weight, depression, vomiting, anorexia, polydipsia, and polyuria. General physical findings included depression, weakness, severe dehydration and a strong acetone odor on the breath. A complete blood count and serum biochemical profiles were leukocytosis, hyperglycemia (286 mg/dl), hypokalemia (2.6 mEq/L), hyponatremia, and high serum fructosamine (600 $\mu$mol/L). In blood gas analysis the cat had acidosis (pH 7.127, p$CO_2$26.7 mmHg). In urinalysis glycosuria and ketouria were appeared. On the basis of clinical signs, serum chemistry, blood gas analysis and urinalysis, diabetic ketoacidosis was diagnosed. Treatment included subcutaneous administration of protamine zinc insulin (0.75 U/head) and intravenous administration of 0.9% saline. Potassium phosphate and sodium bicarbonate was added to the fluids. Serum fructosamine for assessment of glycemic control was measured on occasion calls. On day 296, the patient improved clinically and did not experience any problems resulting from diabetic ketoacidosis.

Nephrogenic diabetes insipidus (NDI) can cause nonobstructive hydronephrosis. Congenital NDI (CNDI) is caused by a genetic mutation. This case report presents a 12-year-old girl who was incidentally diagnosed with nonobstructive hydronephrosis due to NDI caused by AQP2 gene mutation after being evaluated for microscopic hematuria found on routine health examination at school. The patient's medical and family history was unremarkable, and she complained of nocturia only at the time of the clinic visit. Bilateral hydronephrosis on abdominal ultrasonography prompted a water deprivation test, leading to diagnosis of NDI. Genetic study confirmed p.Asn (AAC)123Ser (AGC) in exon 2 of the AQP2 gene. Polyuria and hydronephrosis improved following arginine-vasopressin therapy. CNDI responsive to treatment should be considered as a possible cause of nonobstructive hydroureter.

This study was carried out to determine the effect of renal ischemia on renal function and excretion of amino acid in rabbit. The animal models of renal ischemia induced experimentally by clamping the renal artery for different lengths of time. These results were summarized as follows: 1. Ischemia for 30 or 60 min produced a polyuria which is accompanied by an increase in $Na^+$ excretion. Glomerular filtration rate (GFR) and p-aminohippurate plasma($C_{PAH}$) were not altered by 30 min of ischemia, indicating that transient ischemia results in a marked tubular dysfuction before a reduction in GFR or renal blood flow. 2. Reabsorption of glucose and amino acids such as alanine and lysine was markedly reduced after 30 min of ischemia, and the effect was more pronounced after 60 min of ischemia.
