Yellow Nail Syndrome: Treatment of Lymphedema Using Low Pressure Compression

Chylothorax and Pseudochylothorax

Classically, both chylothorax and pseudochylothorax present as a pleural effusion with a characteristic milky white appearance to the pleural fluid. Although both are rare causes of pleural effusion, they have distinct etiologies and clinical implications, and as a result require different management strategies. Pleural fluid analysis of cholesterol and triglyceride levels is key to differentiating the 2 entities from one another and then guide the clinician to determine the best next steps in evaluation and management.

Yellow nail syndrome: a case report and review of treatment options

BACKGROUND AND AIMS

Yellow nail syndrome is a rare disorder involving characteristic nail changes, lymphedema and chronic respiratory symptoms. Currently there is no definitive treatment and there have been no prospective randomised controlled trials evaluating the available options. In order to strengthen the literature on this topic, we present the case of a 67-year-old man with YNS and a detailed review of current treatment options.

METHODS

We included 40 articles for the final review according to their relevance with the subject.

RESULTS

Data for use of the commonly chosen therapies for YNS remains inconclusive, with small studies and case reports showing mixed results of efficacy.

CONCLUSION

Although the date indicates that it is reasonable to recommend a trial of conservative therapy including vitamin E, antibiotics and compression stockings before pursuing more aggressive or invasive modalities, larger scale studies are required to determine the true efficacy of all treatment options.

Characteristics of patients with yellow nail syndrome and pleural effusion

Yellow nail syndrome (YNS) can be associated with a pleural effusion (PE) but the characteristics of these patients are not well defined. We performed a systematic review across four electronic databases for studies reporting clinical findings, PE characteristics, and most effective treatment of YNS. Case descriptions and retrospective studies were included, unrestricted by year of publication. We reviewed 112 studies (150 patients), spanning a period of nearly 50 years. The male/female ratio was 1.2/1. The median age was 60 years (range: 0-88). Seventy-eight percent were between 41-80 years old. All cases had lymphoedema and 85.6% had yellow nails. PEs were bilateral in 68.3%. The appearance of the fluid was serous in 75.3%, milky in 22.3% and purulent in 3.5%. The PE was an exudate in 94.7% with lymphocytic predominance in 96% with a low count of nucleated cells. In 61 of 66 (92.4%) of patients, pleural fluid protein values were >3 g/dL, and typically higher than pleural fluid LDH. Pleurodesis and decortication/pleurectomy were effective in 81.8% and 88.9% of cases, respectively, in the treatment of symptomatic PEs. The development of YNS and PE occurs between the fifth to eighth decade of life and is associated with lymphoedema. The PE is usually bilateral and behaves as a lymphocyte-predominant exudate. The most effective treatments appear to be pleurodesis and decortication/pleurectomy.
