RESUMEN
Hypospadias is an uncommon sexual development disorder in cats, in which the urethral opening is not in its anatomical location on the penis. The purpose of this report is to describe two cases of hypospadias in the feline species. The first cat was asymptomatic, had a history of bacterial cystitis, and was diagnosed with perineal hypospadias at an appointment for preoperative evaluation of orchiectomy. The second cat had clinical signs of dysuria and pollakiuria for 30 days and had glandular hypospadias. Both cats showed abnormalities in the urinalysis which were suggestive of lower urinary tract disease. For both cases, clinical treatment with antibiotic therapy was performed. In the first patient, surgical treatment consisted of orchiectomy, while in the second animal a perineal urethrostomy and orchiectomy were performed. The cats had a satisfactory recovery after the treatments. Performing a thorough physical examination is essential to diagnose cases of hypospadias and choose the best treatment for each patient.
A hipospadia é uma desordem do desenvolvimento sexual pouco comum nos gatos, na qual a abertura uretral não está em sua localização anatômica do pênis. O objetivo do presente relato é descrever dois casos de hipospadia em felinos domésticos. O primeiro gato era assintomático, tinha histórico de cistite bacteriana prévio, e foi diagnosticado com hipospadia perineal em uma consulta para avaliação pré-cirúrgica de orquiectomia. O segundo gato apresentava sinais clínicos de disúria e polaquiúria há 30 dias e apresentava hipospadia glandular. A partir dos exames complementares, pôde-se observar que os animais, além do defeito anatômico, apresentavam alterações sugestivas de doença do trato urinário inferior. Para ambos os casos, foi realizado o tratamento clínico inicial com antibioticoterapia. No primeiro paciente, optou-se pelo procedimento de orquiectomia, enquanto no segundo animal foram realizadas as técnicas de uretrostomia perineal e orquiectomia. Os gatos mostraram recuperação satisfatória após os tratamentos instituídos. Dessa forma, pode-se observar a importância de se realizar um exame físico minucioso a fim de diagnosticar os casos de hipospadia e escolher o tratamento correto para cada paciente.

In the Neonatal Erythropoietin and Therapeutic Hypothermia Outcomes study, 9/20 erythropoietin-treated vs 12/24 placebo-treated infants with hypoxic-ischemic encephalopathy had acute brain injury. Among infants with acute brain injury, the injury volume was lower in the erythropoietin than the placebo group (P = .004). Higher injury volume correlated with lower 12-month neurodevelopmental scores. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01913340.

OBJECTIVES: To investigate the effects of growth hormone (GH) therapy on craniofacial growth and body proportions in growth hormone deficient children. STUDY DESIGN: By using a cross-sectional study design, we investigated GH effects on craniofacial growth with photographic facial morphometrics, head circumference, and hand and foot size in 52 children with GH deficiency (GHD) treated with GH (0.27 mg/kg/wk) for 0.19 to 15.5 years, compared with untreated children with GHD and normal first-degree relatives. To detect disproportion and to correct for stature, age and height age (HA) SD scores were analyzed. RESULTS: Untreated subjects with GHD had retarded facial height and width (P values=.001) compared with normal controls; small head circumference for age and HA (P=.001); small hands for age (P<.001) that were large for HA (P=.003); and small feet for age (P<.001) that were normal for HA. When compared with normal controls, GH-treated subjects had proportional facial heights but narrower facial widths. Head circumference, however, increased disproportionately to height (P=.001), becoming large for stature, and increasing with duration of therapy and cumulative GH dose (P<.001). Hands and feet grew proportionately to height. CONCLUSION: Growth hormone treatment with conventional doses partially corrects craniofacial deficits and does not adversely affect hand and foot growth but appears to result in excessive head circumference growth.

Facial morphometry using computerised image analysis was performed on patients with growth hormone receptor deficiency (Laron syndrome) from an inbred population of southern Ecuador. Morphometrics were compared for 49 patients, 70 unaffected relatives, and 14 unrelated persons. Patients with growth hormone receptor deficiency showed significant decreases in measures of vertical facial growth as compared to unaffected relatives and unrelated persons with short stature from other causes. This report validates and quantifies the clinical impression of foreshortened facies in growth hormone receptor deficiency.
