Acute kidney injury (AKI) and autosomal dominant polycystic kidney disease (ADPKD) are considered separate entities that both frequently cause renal failure. Since ADPKD appears to depend on a polycystin-1 (Pc1) or Pc2 dosage mechanism, we investigated whether slow progression of cystogenesis in two Pkd1 transgenic mouse models can be accelerated with moderate ischemia-reperfusion injury (IRI). Transient unilateral left ischemic kidneys in both nontransgenic and transgenic mice reproducibly develop tubular dilatations, cysts, and typical PKD cellular defects within 3 mo post-IRI...

Iris cysts can arise from iris pigment epithelium or stroma. We present 3 cases of iris cysts which have been managed in different ways. In a one-month neonate, cyst was punctured with keratome and gentle diode laser endophotocoagulation was applied to the base. A2.5-month infant presented with watering and blepharospasm since birth. Clear fluid was aspirated from the cyst with a 27-gauge needle and Ethanol 96% (ETOH) was injected into the cyst and then aspirated. It was followed by injection/aspiration of 0...

We present two cases of an HIV-associated parotid gland cyst. One case was a 36-year-old HIV infected woman. She was diagnosed with HIV infection and presented with slowly enlarged parotid gland cysts together with elevation of HIV viral RNA copies/mL in her serum. She was performed parotid gland biopsy under the general anesthesia. The histopathologic analysis revealed negative HIV p24-antigen in her parotid gland tissue. The other case was a 43-year-old man found his parotid gland swelling shortly after highly active antiretroviral therapy (HAART)...

PURPOSE: To report the case of an anterior chamber epithelial cyst after uncomplicated deep anterior lamellar keratoplasty (DALK) treated with a tissue-sparing surgical technique. METHODS: A 35-year-old female patient underwent DALK in her OS because of stage IV keratoconus. The surgery was uneventful, and 3 months postoperatively, best-corrected visual acuity (BCVA) was 20/25. By the sixth postoperative month, a cystic iris lesion was noticed. The lesion grew progressively larger, and BCVA dropped to 20/63 in OS...

The cotton rat (Sigmodon hispidus) is a laboratory rodent that has been used for studies on human infectious diseases. In the present study, we observed that female cotton rats, not the male cotton rats, developed chronic anemia characterized by reduced red blood cell, hemoglobin, and hematocrit levels from 5 to 9 months of age without any changes in the mean corpuscular hemoglobin and volume levels. In peripheral blood, the reticulocyte count did not increase in response to anemia in female cotton rats, and no extramedullary hematopoiesis was observed in the liver or spleen...

Purpose. To investigate the value of optical coherence tomography (OCT) for differentiation between choroidal melanoma and metastasis based on characteristics of the anterior choroidal surface and the chorioretinal interface. Methods. This retrospective observational case series included 29 patients with untreated choroidal melanomas and 21 patients with untreated choroidal metastases. Regularity and lobularity characteristics of the anterior choroidal surface were evaluated in a masked manner. Retinal and retinal pigment epithelium (RPE) findings were documented as well...

An unusual case of a free-floating peripheral pigmented cyst in the anterior chamber is presented. A 30-year-old Caucasian male presented reporting a visual defect on his right eye in prone position over the past year. Slit-lamp examination revealed a small pigmented free-floating peripheral iris cyst at the 6 o'clock position in the anterior chamber. Ultrasound biomicroscopy revealed an unfixed epithelial pigmented cyst with an extremely thin wall and no internal reflectivity. Due to the lack of severity of visual disturbance of the patient, no surgical treatment was indicated...

Sarcocystis spp. are cyst-forming coccidia that infect numerous animals species, including several livestock species. Despite the importance of sheep and goat production in Brazil, little it is known about the Sarcocystis species that infect small ruminants in the country and their potential impact on meat condemnation due to the presence of macroscopic cysts of the parasite. The aims of the present study were to determine the frequency of infection by Sarcocystis spp. in goats and sheep intended for human consumption in Bahia State, Brazil, as well as to identify the parasite species in selected samples...

PURPOSE: Mucogenic glaucoma is an unusual form of secondary open-angle glaucoma caused by intracameral ectopic mucus-producing epithelium. To date, only 3 cases have been described in detail. Numerous goblet cells in the specimens indicated a possible conjunctival origin. We immunohistochemically characterized the implanted epithelium from an iris cyst responsible for mucogenic glaucoma. METHODS: A series of immunostaining analyses were performed on a sector-iridectomy specimen derived from an eye with mucogenic glaucoma and a history of limbal penetrating injury...

Posttraumatic iris implantation cysts are rare ocular findings that are often associated with poor visual outcomes. Iris implantation cysts can present clinicians with diagnostic and therapeutic challenges given their variable presentations and frequently destructive nature. In this paper, we provide descriptions of two unusual cases of posttraumatic iris implantation cysts. The first case is of a recurrent keratin-filled iris implantation cyst that developed after open globe injury and intraocular implantation of cilia and was treated with cyst debulking procedures, injections of 5-Fluorouracil, and iridocyclectomy...
