Imaging
Those who care for patients with pulmonary, critical care or sleep disorders rely heavily on chest radiology and pathology to determine diagnoses. The Southwest Journal of Pulmonary, Critical Care & Sleep publishes case-based articles with characteristic chest imaging and related pathology.
The editor of this section will oversee and coordinate the publication of a core of the most important chest imaging topics. In doing so, they encourage the submission of unsolicited manuscripts. It cannot be overemphasized that both radiologic and pathologic images must be of excellent quality. As a rule, 600 DPI is sufficient for radiographic and pathologic images. Taking pictures of plain chest radiographs and CT scans with a digital camera is strongly discouraged. The figures should be cited in the text and numbered consecutively. The stain used for pathology specimens and magnification should be mentioned in the figure legend.

Medical Image of the Week: Yellow Nail Syndrome
Figure 1. Photographs showing the patient’s discolored, yellowish nails.
Figure 2. Representative images from the thoracic CT scan in lung windows showing bronchiectasis most marked in the left upper lobe.
A 67-year-old woman with a previous history of yellow nail syndrome presented with a long history of cough, increased sputum production, recurrent swelling in her lower extremities and recurrent respiratory infections. Physical examination revealed non-pitting edema in the lower extremities and discolored nails (Figure 1). A thoracic CT scan showed bronchiectasis in the left upper lobe (Figure 2). She did not have a history of pleural effusions or chronic sinusitis.
Yellow nail syndrome is very rare disorder associating yellow nail discoloration, bronchiectasis and lymphedema (1). Other frequent manifestations include sinusitis and recurrent pleural effusions. The disease is most frequently isolated but may be associated with other diseases implicating the lymphatic system, autoimmune diseases or cancers. The symptoms result from lymphatic impairment but the cause of the impairment is unknown. Treatment is symptomatic for each component. Vitamin E, combined with fluconazole, is usually prescribed to treat yellow nails and achieves a partial or complete response. Spontaneous resolution is also possible. Although prognosis is usually considered to be good, a Kaplan–Meier survival curve estimated median survival at 132 months, shorter than that of a paired-control population (2).
