Several Months' Duration (several + month_duration)
Selected AbstractsSurgical removal of an ovarian tumour in a koi carp (Cyprinus carpio)AUSTRALIAN VETERINARY JOURNAL, Issue 5 2006SR RAIDAL Ultrasonography, radiography and exploratory coeliotomy were used to diagnose and treat a large intracoelomic neoplasm from a female koi carp (Cyprinus carpio) presented for abdominal enlargement of several months duration. Feed was withheld for 1 week immediately prior to surgery and the fish was sedated with isoeugenol (AQUI-S®) at a dose rate of 10 mL/L to facilitate diagnostic imaging techniques. Surgical anaesthesia was induced by adding tricaine (MS-222) 50 mg/L to the water and an exploratory coeliotomy and tumour removal was performed. The fish was allowed to recover in fresh water at 18°C and salt was added slowly to the water over a period of 1 hour to a concentration of 5 g/L This concentration was maintained in a recovery pond for 1 week postoperatively. Enrofloxacin was administered intramuscularly (10 mg/kg) immediately, 3 days and 1 week postoperatively. A diagnosis of undifferentiated ovarian carcinoma was made on the basis of the histological appearance of the neoplasm and immunohistochemical staining. [source] Identification of focal adenomyosis as a uterine lesion in two dogsJOURNAL OF SMALL ANIMAL PRACTICE, Issue 8 2001N. M. Stöckun-Gautschi A focal uterine adenomyosis is described in two bitches. In both cases, the uterus showed knobbly enlargements of 4 to 8 cm in diameter, which resulted in distinct clinical symptoms. Other pathological changes of the uterus were not present. One bitch was presented because of a history of vaginal discharge of several months' duration. Radiographs, as well as ultrasonography, revealed a soft tissue lesion at the cervix. The other bitch showed a marked reduction In its general condition and a sudden onset of a tense abdomen. Radiologically, a lesion of soft tissue opacity was observed in the mid-abdomen and was seen to originate from the left uterine horn during exploratory laparotomy. A torsion of the lesion was present, which explained the clinical signs in this second case. [source] Stones in the lacrimal gland: a rare conditionACTA OPHTHALMOLOGICA, Issue 6 2009Jakob Halborg Abstract. Purpose:, Stones (dacryoliths) in the lacrimal drainage system are relatively common. However, stones in the lacrimal gland itself are very rare. We present three cases of lacrimal gland stones and describe the clinical and histopathological characteristics and composition of the stones. Methods:, Three patients presented with swelling in the lateral canthal region of several months' duration. Clinical examination in each case revealed a mass adjacent to the lacrimal gland. We carried out surgical excision, histological examination and Raman spectroscopy. Results:, Histopathological examination of the excised material showed an eosinophilic, amorphic material organized in lamellae and localized in a ductule. The findings were consistent with a stone in the lacrimal gland in all three cases. All stones were composed of proteins of similar types. After surgery, the three patients healed without complications. Conclusions:, Lacrimal gland stones represent a very rare but relevant differential diagnosis when a patient presents with unilateral persistent conjunctivitis or with a tumour in the lateral canthus. Treatment is excision under local anaesthesia. [source] Report of an unusual case of a conjunctival cyst with Liesegang ringsCLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 3 2009Jaime Levy MD Abstract Liesegang rings are laminated precipitation structures well recognized in the field of chemistry. We present a rare case of a 64-year-old man who sought examination for a conjunctival cystic lesion of several months' duration, located in the right nasal bulbar conjunctiva near the plica semilunaris. The lesion was excised completely and uneventfully under local anaesthesia. Histopathological examination revealed a large folded cyst in the substantia propria. The cyst contained multiple eosinophilic concentrically spherical and oval structures of variable size with an amorphous central core compatible with Liesegang rings. No fungal or parasitic organisms were identified. This is the first photographically documented case of Liesegang rings appearing in the conjunctiva. Liesegang ring formation should be taken into account during histopathological examination of a conjunctival cyst and not be misdiagnosed as a parasitic infection. [source] | ||||||||||
