Abdominal Ultrasound Examination

Oesophagostomosis is a zoonotic disease caused by nematodes of the genus Oesophagostomum in the intestinal walls of many species, including ruminants, pigs, humans, and nonhuman primates. Although great apes appear to tolerate the parasite in the wild, they can develop a clinical form that can lead to death in captivity and the natural environment. At the Primatology Centre of the International Centre for Medical Research in Franceville (CIRMF) in Gabon, we recorded 4 deaths of chimpanzees (Pan t. troglodytes) caused by Oesophagostomum spp. between 2015 and 2019. In each case, coprological analysis was positive for strongylid eggs and abdominal ultrasound revealed nodules about 4 cm in diameter on the intestinal and abdominal walls. Albendazole treatments administered by mouth in two doses of 400 mg six months apart resulted in the disappearance of the parasite in coprological samples but the chimpanzees still died. Autopsies carried out on all four chimpanzees revealed a rupture of the cysts and a discharge of pus into the abdomen in each case. We report surgical management involving the removal of Oesophagostomum spp. cysts from a chimpanzee following coprological analysis and abdominal ultrasound examination. Surgical exploration confirmed the fragility of the cystic walls, the rupture of which we avoided. This 5th new case of Oesophagostomum ssp. nodules recovered without complications following the operation and could rejoin his group. We suggest that surgical intervention should be considered in similar cases in captive primates, especially chimpanzees.

A 31-year-old female was in the 13th week of pregnancy when an abdominal ultrasound examination revealed a large retroperitoneal tumour. Magnetic resonance imaging was carried out and the imaging described a 10-cm mass in diameter extending from the right kidney. Given that the patient was in her first trimester and that there was a suspicion of malignancy, further surgical exploration of the tumour was warranted. During the operation, the tumour was removed, but nephrectomy was not necessary. Histologic analysis of the resected tumour showed a mucinous cystic adenoma, and no signs of malignancy were present. Following the surgery, the pregnancy was otherwise uneventful and further complications did not occur. This case illustrates that surgery is recommended in patients with a retroperitoneal tumour early during a pregnancy, when a malignancy cannot be excluded.

Appendiceal mucocele (AM) is a rare entity that can present in a variety of clinical syndrome. The prevalence is 0.2- 0.4 % among appendicectomies.1 A 48 Years old male patient came to our Centre for Nuclear Medicine and Ultrasound (CNMU), Rajshahi for abdominal ultrasound examination. He had pain with vomiting and feeling of lumpiness in right side of lower abdomen. Ultrasonography (US) showed an elongated regular outlined semi-cystic lesion in right iliac fossa. Laparotomy done, per-operative finding reveled AM. Post-operatively histopathological examination report revealed AM. TAJ 2011; 24(1): 54-56

Abdominal Ultrasound Examination

Objectives Morphologic anomalies of the feline gallbladder (GB) have been previously reported in the literature. These morphologic variants are frequently encountered on routine abdominal ultrasound examination. The aim of this study was to provide an ultrasonographic classification system of these variants and document the overall incidence in the feline population. Methods A prospective, descriptive study was undertaken; cats that had an abdominal ultrasound examination that included at least one sagittal and transverse plane image of the GB were included. GB shape was evaluated and categorized based on a classification scheme of morphologic variants modified from the human literature. Septated (S), bilobed (B1, B2, B3), duplex (D) and complex (C) categories were described. Results Of 516 cats included in the study, 389 had normal GB morphology, while 127 had anomalous GB morphology. The overall incidence rate of anomalous GB morphology was 24.61%. When examined by morphologic type, the septated (S) morphology had an incidence of 9.69%. A bilobed (B) morphology was the most commonly observed classification; incidence was 14.35% within our population; incidence of B1, B2 and B3 subtypes were 2.91%, 6.98% and 4.46%, respectively. Duplex GBs only made up 0.39% of the total population. The incidence of complex (C) morphologies was 0.19%. Conclusions and relevance The incidence of GB morphologic anomalies was higher in our population than previously reported. Identification of these anomalies on routine ultrasound evaluation is common; numerous different morphologies can be identified and a standardized classification scheme is proposed. Complete evaluation of morphology can be challenging, particularly with regard to cystic duct anatomy. Clinical significance is uncertain and future studies are warranted to determine the relationship between morphologic variants and hepatobiliary disease.

Abdominal Ultrasound Examination

This paper describes a prospective three-year study using abdominal ultrasound examination in 114 new CAPD patients. Gallbladder disease was common (22.8%) and four of 16 patients with gallstones (25%) required cholecystectomy after 1–14 (i 7.8 months) on CAPD. Two of these four had evidence of peritonitis in association with cholecystitis. Also we analyzed the clinical course of eight patients on chronic PD who underwent cholecystectomy. They had no serious morbidity, and all returned to chronic PD. While abdominal pain is one of the main features of CAPD-related peritonitis, other causes of abdominal pain may be more difficult to evaluate in the patient on peritoneal dialysis (PD); such causes potentially are more serious because they threaten the continuance of PD as a mode of therapy. Cholecystitis related to cholelithiasis is one such possible cause of abdominal pain. However, since ultrasonography can reliably and non-invasively detect the presence of gallstones, we have used it prospectively to screen patients entering our CAPD training program. This paper reports our findings and the subsequent course of those found to have gallstones during a three-year period. In addition we also reviewed the feasibility of cholecystectomy, its hazards and outcome in eight patients on chronic peritoneal dialysis who underwent this procedure at Toronto Western Hospital in the past seven years.

Abdominal Ultrasound Examination

Abdominal ultrasound examination in an 11-year-old, intact, female Labrador dog with hepatic disease revealed a nodular swelling of the left adrenal gland. Hyperadrenocorticism was suspected, but endocrine tests were negative. At the owner's request, an adrenalectomy was performed. Grossly, a nodular mass protruded from the external surface of the left adrenal gland and in cut section was hemorrhagic and effaced the cortical and medullary regions. Histologic examination revealed a cortical neoplasm with medullary involvement. The mass was composed of well-differentiated adipose cells, megakaryocytes, hematopoietic cells, and macrophages containing hemosiderin deposits. A diagnosis of cortical adrenal myelolipoma was made.

AbstractThe creation of novel communicative acts is an essential element of human language. Although some research suggests the presence of this ability in great apes, this claim remains controversial. Here, we use orang-utans (Pongo spp.) to systematically assess the effect of the wild-captive contrast on the repertoire size of communicative acts. We find that individual communicative repertoires are significantly larger in captive compared to wild settings, irrespective of species, age-sex class or sampling effort. Twenty percent of the orang-utan repertoire in captivity were not observed in the wild. In Sumatran orang-utans, the more sociable species, functional specificity was also higher in captive versus wild settings. We thus conclude that orang-utans, when exposed to a more sociable and terrestrial lifestyle, have the behavioural plasticity to invent new communicative behaviours that are highly functionally specific. This productive capacity by great apes is a major prerequisite for the evolution of language and seems to be ancestral in the hominid lineage.
