The purpose of this study is to establish renal resistive index (RRI) of normal kidneys in puppies aged from newborn to 20 weeks of age and to determine the age at which RRI reaches adult dog values. Six healthy adult intact beagles and six puppies from 1 day after birth to 20 weeks of age were used. In the adult dogs, the ultrasonographic scans were performed once, and in the puppies, the ultrasonographic studies were performed on the first day after birth and at 1, 2, 3, 4, 6, 8, 12, 16, and 20 weeks of age. RRI was obtained at the interlobular and arcuate arteries in each kidney. There were no statistical differences between the RRI values obtained between the right and left kidney nor between intrarenal arteries (interlobar and arcuate). The RRI was the highest during the first weeks of life, after which it declined gradually with increasing age reaching adult dog values at 12 weeks of age. In conclusion, the normal mean RRI is age dependent in dogs. Twelve weeks can be regarded as the age at which adult mean RRI criteria can be applied to puppies.The inhibition of acetolactate synthase (ALS; EC 2.2.1.6), an enzyme located in the biosynthetic pathway of branched-chain amino acids, is the target site of the herbicide imazamox. One of the physiological effects triggered after ALS inhibition is the induction of aerobic ethanol fermentation. The objective of this study was to unravel if fermentation induction is related to the toxicity of the herbicide or if it is a plant defense mechanism. Pea plants were exposed to two different times of hypoxia before herbicide application in order to induce the ethanol fermentation pathway, and the physiological response after herbicide application was evaluated at the level of carbohydrates and amino acid profile. The effects of the herbicide on total soluble sugars and starch accumulation, and changes in specific amino acids (branched-chain, amide, and acidic) were attenuated if plants were subjected to hypoxia before herbicide application. These results suggest that fermentation is a plant defense mechanism that decreases the herbicidal effect.Dentistry has seen a slow trend toward person-centred care (PCC), with most approaches developed by scholars who have tried to progress away from disease-centred care. Unfortunately, the perspectives and experiences of underprivileged people have not been considered in the development of these approaches. Our objective was thus to understand underprivileged people's experiences and expectations about dental care and contribute to the development of person-centred dentistry. We conducted a qualitative descriptive study with a sample of 13 people living in poverty. We used a maximum variation sampling strategy and selected them among the users of a free dental clinic in Montreal, Canada. We conducted semi-structured interviews that we audio recorded, transcribed verbatim, and thematically analysed. Our main finding is that participants wanted to feel human and respected by dentists. More specifically, they wanted to be more involved in the dental care process through quality time and empathetic conversations with the dentist. They also wished for an exchange of information free of technical terms and built on mutual trust. In conclusion, person-centred dental care models should emphasize empathy, trust, and quality care beyond technical skills. Clinicians should provide comprehensive information in dental encounters and treat their patients as whole persons.
Dysphagia is a common presenting symptom in elderly people. Nevertheless, dysphagia resulting from diffuse idiopathic skeletal hyperostosis (DISH) of patients' cervical spine may be due to several factors. Despite computed tomography scan showing the size and shape of osteophytes, endoscopy may be necessary to exclude other intrinsic causes of dysphagia. Due to the anatomic variation of the pharynx secondary to DISH, patients undergoing endoscopy are at risk of perforation. Once perforation occurs, inappropriate treatments may finally lead to an irretrievable outcome.
A 58-year-old male patient with a 20-day history of dysphagia initially visited an ear-nose-throat (ENT) doctor. He had no neck pain and no other history of cervical disease.
This patient with dysphagia due to DISH of the cervical spine underwent laryngoscopy to exclude other causes. Pharyngeal perforation resulted as a complication of the procedure.
The patient underwent laryngoscopy and biopsy by an ENT doctor to exclude intrinsic caus, especially biopsy. Once perforation occurs, operative treatment may be more appropriate and effective.
DISH involving the cervical spine is a complicated cause of dysphagia. Due to the anatomic variation of the pharynx secondary to DISH, patients undergoing endoscopy are at risk of perforation. If other intrinsic causes of dysphagia have to be excluded with the aid of endoscopy, plain films and computed tomography images should be read carefully first. To minimize the risk of perforation, it is necessary to perform endoscopy extremely carefully, especially biopsy. Once perforation occurs, operative treatment may be more appropriate and effective.
Adult intussusception is rarely observed, accounting for about 5% of all cases of intussusception. Most ileal lipomas are asymptomatic and do not need any special treatment. Herein, we describe a case with ileocolic intussusception caused by ileal lipoma.
A 27-year-old woman complaints of intermittent abdominal pain for 10 days.
Abdominal computed tomography demonstrated ileocolic intussusception. Colonoscopy revealed a spherical polypoid lesion with surface capillary rising from the lateral wall of the ileum. A diagnosis of ileocolic intussusception was made.
The patient underwent primary resection of the intussuscepted intestine after which an end-to-end anastomosis was performed.
Histopathology report confirmed a 4.5 cm × 3.5 cm lipoma in the terminal ileum. The patient was discharged on a postoperative day 9 without complications.
We describe the difficulties in diagnosis and treatment of this rare cause of intussusception and review the literature on adult intussusceptions. find more The ileal lipoma is a very rare cause of ileocolic intussusception.
