We report a case of melanoma arising in a large nevus spilus. On histologic examination, the nevus spilus had diagnostic features of melanocytic dysplasia. Further characterization by flow cytometry showed DNA-aneuploidy within the melanoma as well as in one of the darker pigmented papules within the nevus spilus. The significance of this finding and a review of melanomas originating in nevi spili are presented. 相似文献

重度溃疡性结肠炎通常病情重、发展快,出现危及生命的并发症和结肠切除的风险特别高.对于溃疡性结肠炎,当内科治疗无效时可考虑手术治疗.1例重度溃疡性结肠炎经采用常规药物治疗无效,出现低血压性休克等并发症,达到行外科手术的指征,因患者为年轻未婚、未恋女性,术后存在影响生活质量、性功能障碍、不孕等风险,故经分析内科疗效不佳的原因后采取规范治疗方案,充分增强营养支持,调节肠道微生态等个体化治疗,患者由重度转为轻度.对该患者的内科优化治疗提示营养支持在溃疡性结肠炎中与药物治疗同样重要. 相似文献

To look at the prevalence of phonatory symptoms in patients with type 2 diabetes mellitus. The correlation between these symptoms with duration of the disease, glycemic control, and neuropathy will be described. A total of 105 consecutive patients diagnosed with type 2 diabetes mellitus by their primary endocrinologist were evaluated. A control group consisting of 33 healthy subjects was recruited for this study. Demographic data included: age, gender, allergy, smoking, duration of the disease, glycemic control, and presence or absence of neuropathy. Subjects were also asked about the presence or absence of the following symptoms: hoarseness, vocal tiring or fatigue, vocal straining, and aphonia or complete loss of voice. Patients were also asked to fill out the Voice Handicap Index 10. The mean age of patients with diabetes was 53.21 + 9.68 years with male-to-female ratio of 2/3. The most common phonatory symptoms were vocal tiring or fatigue and hoarseness (34.3 and 33.3 %). There was a significant difference in the prevalence of hoarseness and vocal straining (p value 0.045 and 0.015, respectively) compared to controls. There was a significant correlation between glycemic control, neuropathy, and hoarseness (p value 0.030 and 0.001, respectively). Vocal straining and aphonia also correlated significantly with the presence of neuropathy. Close to 16 % of diabetic patients had a VHI-10 above or equal to 7. Diabetic patients are more likely to have phonatory symptoms compared to controls, namely straining and hoarseness. One out of seven patients with diabetes has reported that phonatory symptoms had a significant impact on their quality of life. The presence of neuropathy and poor glycemic control should alert the treating physician to these vocal complaints. 相似文献

Background Woolly hair (WH) belongs to a family of disorders characterized by hair shaft anomalies that clinically presents with tightly curled hair, which can be divided into syndromic and non‐syndromic forms of WH. We have recently identified mutations in both LPAR6/P2RY5 and LIPH that are associated with autosomal recessive woolly hair (ARWH). Objective To study the underlying genetic causes of autosomal woolly hair in Pakistani population. Methods We studied 10 Pakistani families with ARWH for mutations in LPAR6/P2RY5 and LIPH and then performed haplotype analysis to confirm their segregation in the families. Results We identified five mutations in LPAR6/P2RY5, among which three were recurrent and two were novel in eight Pakistani families. We then showed that two of the mutations in LPAR6/P2RY5 are founder mutations in Pakistani families. Moreover, we identified two recurrent mutations in the LIPH gene in two Pakistani families. Conclusion Our study extends the spectrum of mutations in LPAR6/P2RY5 gene and underscores those mutations in LPAR6/P2RY5 and LIPH result in similar phenotypes. 相似文献

Dapsone (4,4'-diaminodiphenylsulfone) is the only remaining sulfone used in anthropoid therapeutics and is commercially available as an oral formulation, an inhaled preparation, and a 5% or 7.5% cream. Dapsone has antimicrobial effects stemming from its sulfonamide-like ability to inhibit the synthesis of dihydrofolic acid. It also has anti-inflammatory properties such as inhibiting the production of reactive oxygen species, reducing the effect of eosinophil peroxidase on mast cells and down-regulating neutrophil-mediated inflammatory responses. This allows for its use in the treatment of a wide variety of inflammatory and infectious skin conditions. Currently in dermatology, the US Food and Drug Administration (FDA)-approved indications for dapsone are leprosy, dermatitis herpetiformis, and acne vulgaris. However, it proved itself as an adjunctive therapeutic agent to many other skin disorders. In this review, we discuss existing evidence on the mechanisms of action of dapsone, its FDA-approved indications, off-label uses, and side effects. 相似文献

The Wnt signalling pathway is a major pathway involved in the embryogenic development of the various organs of the body. Appropriate signalling in this pathway relies on the proper functioning of several proteins including the R‐spondin family of proteins. Deactivating mutations in R‐spondin 4 are associated with anonychia. We present the case of a 26‐year‐old man presenting with anonychia of the 20 nails, which had been present since birth. Using genetic studies, we identified a novel nonsense mutation, c.164‐165TC>AA, characterized by two consecutive mismatch bases. To our knowledge, this mutation is the first to be reported in R‐spondin 4 in a Lebanese population. Evaluating new patients with anonychia provides fruitful clinical and molecular findings. 相似文献
