A 7-year-old neutered male Korean domestic short-haired cat was referred to our clinic to treat constipation which had persisted for 6 months. The rectal examination revealed narrowing of the right lateral portion of the pelvic canal. A reduced pelvic canal diameter by pelvic fracture malunion was revealed on radiography. The pelvic canal diameter ratio measured from preoperative was 0.68. Based on rectal and radiographic examinations, constipation caused by pelvic canal narrowing was confirmed. Pelvic symphyseal distraction-osteotomy and iliac wedge osteotomy were performed. An iliac osteotomy of the ilium was performed to ease the pelvic symphyseal distraction. After the symphysis was split longitudinally, pelvic symphyseal distraction was maintained by using a spacer made of poly-methyl-methacrylate. The osteotomy of the ilium was fixed using a bone plate and screws. Increased pelvic canal diameter was confirmed on post-operative radiography and the postoperative pelvic canal diameter ratio was 0.91. The patient received antibiotics, NSAIDs, crystalloids and Lactulose for post-operative care. The cat recovered normal defecation abilities and did not have constipation at one week postoperatively. No episodes of constipation persisting longer than 6 months have been reported by owners in previous studies. Pelvic symphyseal distraction osteotomy and iliac wedge osteotomy may prove to be a useful surgical procedure to treat pelvic canal stenosis that is caused by pelvic fracture malunion.

In this paper, we developed a mobile student ID providing a self sovereignty identity (SSI) which replaces the conventional plastic-type student ID that includes private information of a student such as a name, a student number, a facial photo, etc. The implemented mobile student ID solves the problem of exposing student's identity due to a loss or a theft of a plastic-type student ID, and it has a structure and process of FRANCHISE model which is developed by a concept of a decentralized Identity(DID) of a Blockchain, in which specialized for convenience as an electronic student ID through an application on a smart phone device. In addition, it protects student's privacy by controlling personal information on oneself. By using a smartphone, not only it easily identifies the student but also it expands to several services such as participation in school events, online authentication, and a student's exchange program among colleges.

This study was performed to evaluate the embolized kidney and contralateral normal kidney using computed tomography (CT) and enhanced computed tomography. Experimental hydronephrosis was induced by ligation of unilateral ureter in Beagle dogs. Renal artery embolization was performed using selective catheterization in the hydronephrotic kidney of seven dogs and EKG, $SpO_2$, body temperature, pulse, and repiratory rate were within normal ranges during procedures. Iohexol-ethanol solution was used as embolic material. There were no dogs expired after TAE-Ra and no side effects associated with regurgitation of iohexol-ehtanol solution. Revascularization of renal artery was not found in angiography in dogs treated by TAE-RA at immediately after TAE-RA and 14 days after TAE-RA. CT showed dilation of urinary collection system and ventral displacement of spleen at 14 days after TAE-RA in one dog not treated by TAE-RA and experimental group treated by TAE-Ra. CT two month after TAE-RA showed the shrunken embolized kidney in experimental group. Transverse CT with contrast enhancement demonstrated the increase of signal intensity at thinned renal cortex in control group not treated by TAE-Ra at 30 days and 60 days, however, there was no increase of signal intensity at shrunken embolized kidney at 60 days after TAE-RA. CT was useful modality for evaluation of the morphology and the size of embolized kidney and contralateral normal kidney. Enhanced CT was availabel for the detection of revascularization of renal artery after TAE-RA in dogs with hydronephrosis. It is conclued that CT is useful modality for the monitoring of the revascularization of the renal artery after TAE-RA.

Purpose: The purpose of this study was to evaluate the accuracy of Tc-99m DTPA diuretic renal scans in children with dilated upper urinary tract. Materials and Methods: We reviewed diuretic renal scans of 14 pediatric patients (age range: 3 days to 4 years) with unilateral hydronephrosis diagnosed by ultrasonography. Diuretic renal scan was done using Tc-99m DTPA and standardized protocol. In 3 neonates, diuretic renal scans were performed within 1 week and 3-7 months after birth. Results: Six patients required Pyeloplasty and eight were managed conservatively. All 6 patients requiring Pyeloplasty were diagnosed as having ureteropelvic junction obstruction in the diuretic renal scan. In these 6 patients, post-operative renal scans at 3-12 months after surgery were converted to nonobstructive pattern in 5 and a nonfunctioning pattern in 1. In 3 patients who underwent diuretic renal scan within 1 week after birth, nonobstructive patterns of initial scan were converted to obstructive patterns in the follow-up scan. However, all patients with nonobstructive diuretic renal scans performed after the neonatal period did well on serial ultrasonography and showed favorable clinical outcome without progression to obstruction. Conclusion: Tc-99m DTPA diuretic renal scan with standardized protocol is useful in assessing suspected ureteropelvic junction obstruction in children as an initial diagnostic or post-operative follow-up modality. Nonobstructive or indeterminate scan results in the neonatal period requires follow-up scan to monitor development of the obstructive pattern.

Hydrosyringomyelia is a dilation of the spinal cord central canal. In human it may be caused by congenital malformations such as Dandy-Walker syndrome and Chiari malformations or may be acquired as a result of infection, trauma or neoplasia. Hydrocephalus is an excessive accumulation of cerebrospinal fluid within the ventricles and occipital dysplasia is the dorsal extension of the foramen magnum. Hydrosyringomyelia and hydrocephalus can be confirmed by computed tomography or magnetic resonance imaging (MRI). A 3-year-old male maltese was presented with a history of long-term seizure. Blood examination was all unremarkable. On rostrodorsal-caudoventral oblique radiograph of the skull showed severe occipital dysplasia. On brain sonography through the persistent fontanelle, severe lateral ventriculomegaly was revealed. MRI examination revealed hydrocephalus and hydrosyringomyelia. Diuretic therapy didn't reduce clinical symptoms and surgical decompression was conducted. The dog responded well with ventriculo-peritoneal shunting. MRI is the most superior modality to diagnose hydrocephalus and hydrosyringomyelia, to plan therapy and to determine the prognosis.

Intestinal obstruction is not uncommon in infants. The common causes of intestinal obstruction in the neonatal period are Hirschsprung disease, intestinal atresia, meconium ileus, and intussusception. However, small bowel obstruction caused by a congenital band is very rare. We report a 27-day-old baby who was admitted with abdominal distension and fever. The abdominal X-ray revealed massive bowel dilatation and the contrast gastrografin enema suggested a distal small bowel obstruction. The explolaparotomy showed small bowel entrapment due to an unusual anomalous congenital band.

애완동물의 건강유지, 생산성향상, 질병유발 및 치유경과에 미치는 영양과 식이요법의 중요성은 최근 20여년동안에 수의술에 크게 증대되어왔다. 대부분의 애완동물가는 영양관리에 관하여 관행적인 먹이 급여 이외에는 어떤 전문지식을 가지고 있지 않다. 1988년에 퓨리나코리아가 애견용 고형사료를 생산한 이래 백화점의 식품코너에서 애완동물용 사료를 쉽게 접할 수 있게 되었다. 식품으로 급여되는 과잉 영양성 골격계이상과 뇨석증, taurin 결핍과 중심 망막퇴행성 변화및 확장성 심근증의 유발등 소위'nutritional disease',그리고 만성신부전증 치료관리에서 단백질과 인섭취의 제한 ,뇨석증과 간질환의 식이적 조절등은 대표적인 응용예로서 이미 소동물임상에서 일반화되었다. 그러나 우리나라의 경우는 애완동물의 먹이와 식이요법에 관한 전문지식을 학교교육에서 얻지 못함으로 애견가 관리에 많은 문제점이 노출되고 있다. 여기에서는 위와 같은 관점에서 개업수의사에게 필요한 일반지식을 기술하였다.

The most common cause of the decannulation difficulty is the trauma. This may be accidental, iatrogenic such as prolonged intubation, high tracheostomy, secondary infection, formation of granulation tissue, improper use of cannula and wide resection of anterior tracheal wall. Another common cause is psychologic dependency. Treatments may be categorized into dilatation with or without injection of steroid, dilatation and prolonged stent, luminal augmentation and resection of the stenosis with primary reanastomosis. Recently authors experienced a case of the decannulation difficulty in a 2 - year - old which was developed after tracheostomy for the removal of bronchial foreign body and was treated with a silicon T -tube stent with good result.

Bartter syndrome is a rare disorder characterized by the association of hypokalemic hypochloremic metabolic alkalosis, hyperreninemia, hyperaldosteronemia, short stature and nephrocalcinosis. This disorder presents with hyperplasia of juxtaglomerular apparatus on renal biopsy. We experienced a case of late-onset Bartter syndrome with nephrocalcinosis in a 9-year-old boy, whose chief pictures were muscle weakness, short stature, persistent sterile pyuria and microscopic hematuria. We report this case with a brief review of related literatures.
