Introduction Calciphylaxis, a rare obliterative small vessel vasculopathy associated with diabetes mellitus (DM), end-stage renal disease (ESRD), portends a poor prognosis. Because penile involvement is rare, agreement on appropriate diagnosis and management is unclear. Aim To determine the role and effect of penile biopsy for diagnosis and management of penile calciphylaxis. Methods Medical records of three penile calciphylaxis patients from our institution were evaluated. Data collected included age, history of DM, ESRD, and hemodialysis (HD) status, serum calcium (Ca), Ca × phosphorous product (C × P), parathyroid hormone (PTH), performance of biopsy, presence of non-penile cutaneous lesions, intervention, survival, and time from diagnosis to death. PubMed Search for relevant publications from 1995 to 2012 was performed to identify case reports of penile calciphylaxis that provided the same clinical data obtained from the 3 patients from our institution. Main Outcome Measures Clinical evidence for outcomes in patients with penile calciphylaxis after biopsy of penile lesion compared to those without biopsy. Results A total of sixteen patients were identified in the literature and in our institution with clinical data of interest. Overall, 10/16 (62.5%) patients identified with penile calciphylaxis had a penile biopsy, and 7/10 (70%) experienced disease progression, while only 3/10 (30%) stabilized. Mean time to death in this patient population was short, approximately 6.5 months, regardless of type of intervention. Conclusion Based on the results of our study, we argue that conservative measures should be employed as first line therapy for penile calciphylaxis. More importantly, secondary to likely resultant progression of necrosis, penile biopsy is not only unnecessary for diagnosis of penile calciphylaxis, but is also harmful and contraindicated.
The objective of this study was to identify a panel of microRNAs (miRNAs) differentially expressed in high-grade non-muscle invasive (NMI; TaG3–T1G3) urothelial carcinoma that progress to muscle-invasive disease compared to those that remain non-muscle invasive, whether recurrence happens or not. Eighty-nine high-grade NMI urothelial carcinoma lesions were identified and total RNA was extracted from paraffin-embedded tissue. Patients were categorized as either having a non-muscle invasive lesion with no evidence of progression over a 3-year period or as having a similar lesion showing progression to muscle invasion over the same period. In addition, comparison of miRNA expression levels between patients with and without prior intravesical therapy was performed. Total RNA was pooled for microarray analysis in each group (non-progressors and progressors), and qRT-PCR of individual samples validated differential expression between non-progressive and progressive lesions. MiR-32-5p, -224-5p, and -412-3p were associated with cancer-specific survival. Downregulation of miR-203a-3p and miR-205-5p were significantly linked to progression in non-muscle invasive bladder tumors. These miRNAs include those implicated in epithelial mesenchymal transition, previously identified as members of a panel characterizing transition from the non-invasive to invasive phenotype in bladder tumors. Furthermore, we were able to identify specific miRNAs that are linked to postoperative outcome in patients with high grade NMI urothelial carcinoma of the bladder (UCB) that progressed to muscle-invasive (MI) disease.
Background: Human milk, unlike formula feeds, contains long-chain polyunsatured fatty acids, such as docosahexaenoic acid and arachidonic acid which are essential in the development of the central nervous system. If human milk is the optimal food for brain development, and if schizophrenia is a neurodevelopment disorder, might people who become schizophrenic in adult life be less likely to have been breast-fed? Aims: To compare the incidence and length of breast-feeding in patients, siblings and normal controls and to examine the relationship between the duration of breast-feeding and age at onset of schizophrenia. Method: 113 schizophrenic patients were recruited, as were 140 siblings of the patients and 113 nonschizophrenic controls. The breast-feeding history of the patients, their siblings and controls was obtained through interviews with the mothers of the patients and controls. Results: There were no significant differences between groups in the incidence of breast- feeding. The duration of breast-feeding was positively correlated with the age at onset of illness (r = +0.25, p < 0.02). Conclusion: Breast-feeding is no less common in those who develop schizophrenia in later life. However, breast milk might postpone the onset of the illness in schizophrenic patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
