Red, jelly-like sputum - an indicator of possible pneumonia caused by Klebsiella. Green or greenish colored - indicative of potential longstanding respiratory infection (green from degenerative changes in cell debris) as in pneumonia, ruptured lung abscess, chronic infectious bronchitis, and infected bronchiectasis or cystic fibrosis. Rust colored – usually caused by pneumococcal bacteria (in pneumonia), pulmonary embolism, lung cancer or pulmonary tuberculosis. Brownish –potential indicator of chronic bronchitis (greenish/yellowish/brown); chronic pneumonia (whitish-brown); tuberculosis; lung cancer. Yellow, yellowish purulent – an indicator of the sample containing pus. "The sputum color of patients with acute cough and no underlying chronic lung disease does not imply therapeutic consequences such as prescription of antibiotics." The color can provide hints as to effective treatment in chronic bronchitis patients:A yellow-greenish (mucopurulent) color suggests that treatment with antibiotics can reduce symptoms. The green color is caused by degenerating neutrophil verdoperoxidase. Whitish gray sputum color against a white color background (such as a white sink surface) tends to indicate either a specimen from someone who is dehydrated, and/or from an older person, and/or a specimen with a mixed, modest number of eosinophils and maybe some acute inflammatory neutrophil cells (this last choice tends to suggest chronic allergic bronchitis). A white, milky, or opaque (mucoid) appearance means that antibiotics are less likely to be effective in treatment because the likelihood is greater of a viral infection or allergy (even asthma...thick sputum) than of antibiotic-responsive micro-organisms. Foamy white – may come from earlier-phase pulmonary edema. Frothy pink – may indicate more severe pulmonary edema.
Arterial tortuosity syndrome is a rare congenital connective tissue condition disorder characterized by elongation and generalized tortuosity of the major arteries including the aorta. It is associated with hyperextensible skin and hypermobility of joints, however symptoms vary depending on the person. Because ATS is so rare, not much is known about the disease. Signs and symptoms
Among the signs and symptoms demonstrated, by this condition are the following:
Arachnodactyly
Congenital diaphragmatic hernia
Mental dysfunction
Keratoconus
Aortic regurgitation
Blepharophimosis

Genetics
Arterial tortuosity syndrome exhibits autosomal recessive inheritance, and the responsible gene is located at chromosome 20q13. The gene associated with arterial tortuosity syndrome is SLC2A10 and has no less than 23 mutations in those individuals found to have the aforementioned condition. Pathophysiology
The mechanism of this condition is apparently controlled by(or due to) the SLC2A10 gene. The molecular genetic pathogenesis finds that SLC2A10 encodes GLUT10(in nuclear membrane, or the endoplasmic reticulum, the later of which GLUT10 transports DHA into).Clinically speaking, according to one review, the condition of tortuosity is seen more with the advance of age. Diagnosis
In terms of the diagnosis of arterial tortuosity syndrome can be done via genetic testing, as well as the following listed below:
CT
MRI
Echocardiogram
Physical exam(for specific characteristics)

Treatment
The treatment of arterial tortuosity syndrome entails possible surgery for aortic aneurysms, as well as, follow ups which should consist of EGC. The prognosis of this condition has it at about 12% mortality
