The incidence is 1--2% in full-term infants and up to 30% in premature babies. Operation is indicated after 1 year. Prior to age one, the testis may continue to descend into the scrotum. The cause is unknown. Undescended testes fail in spermatogenic function, but may continue to secrete androgens. Spermatogenic failure is progressive; therefore, surgical exploration and scrotal placement of the testis should be performed before 2-years of age. If placement of the testicle into the scrotum is not possible, then orchiectomy is indicated because of the high risk of testicular cancer when the testis is left in an intraabdominal position.The incidence of testicular cancer in an abdominal testis is 30 times higher than the normal population. After 2- years of age orchiectomy is the treatment of choice because of the cancer risk and poor spermatogenesis." } ]

As the valve progressively narrows, the resting diastolic mitral valve gradient, and hence left atrial pressure, increases. This leads to transudation of fluid into the lung interstitium and dyspnea at rest or with minimal exeion. Hemoptysis may occur if the bronchial veins rupture and left atrial dilatation increases the risk for atrial fibrillation and subsequent thromboembolism. The length of the murmur, as opposed to the intensity, is used as a nonspecific guide to stenosis severity. Pulsatile liver may be present." } ]

Three nonsynonymous variants (p.Arg49Cys, p.Arg237Gly, p.Arg453Cys) identified in the probands were not segregating in the respective families. This is not surprising since glaucoma is a multifactorial disease, and multiple factors are likely to be involved in the disease manifestation in these families. However a nonsynonymous variant, p.Arg453Cys (rs3800791), was found in 6 sporadic POAG patients but not in controls, suggesting that it infers increased risk for the disease. In addition, one synonymous variant was found to be associated with sporadic POAG: p.Ala290Ala and the association of the variant with POAG remained significant after correction for multiple testing (uncorrected p-value 0.002, corrected p-value 0.047). The cumulative burden of rare, nonsynonymous variants was significantly higher in sporadic POAG patients compared to control individuals (p-value 0.000006).'], 'labels': ['BACKGROUND', 'METHODS', 'RESULTS'], 'meshes': ['Adolescent', 'Adult', 'Amino Acid Sequence', 'Animals', 'Cohort Studies', 'Female', 'Genetic Variation', 'Glaucoma, Open-Angle', 'Humans', 'Male', 'Middle Aged', 'Molecular Sequence Data', 'Pedigree', 'Suppressor of Cytokine Signaling Proteins', 'Young Adult']}" }, { "from": "gpt", "value": "Answer: yes" } ]
