Prolonged bleeding
has been reported following strabismus surgery in patients with the syndrome. Prognosis
The course of HPS has been mild in rare instances of the disorder, however, the general prognosis is still considered to be poor.The disease can cause dysfunctions of the lungs, intestine, kidneys, and heart. The major complication of most forms of the disorder is pulmonary fibrosis, which typically exhibits in patients ages 40–50 years. This is a fatal complication seen in many forms of HPS, and is the usual cause of death from the disorder. HPS patients who develop pulmonary fibrosis typically have type 1 or type 4. Research
HPS is one of the rare lung diseases currently being studied by The Rare Lung Diseases Consortium (RLDC). The RLDC is part of the Rare Diseases Clinical Research Network (RDCRN), an initiative of the Office of Rare Diseases Research (ORDR), of the National Center for Advancing Translational Sciences (NCATS). The RLDC is dedicated to developing new diagnostics and therapeutics for patients with rare lung diseases, through collaboration between the NIH, patient organizations and clinical investigators.

Buried penis (also known as hidden penis or retractile penis) is a congenital or acquired condition in which the penis is partially or completely hidden below the surface of the skin. A buried penis can lead to urinary difficulties, poor hygiene, infection, and inhibition of normal sexual function.Buried penis is different than micropenis, which is an abnormally small, normally structured penis with a stretched penile length of less than 2.5 standard deviations below the mean for age or stage of sexual development of the patient. History
Buried penis was first described by Edward Lawrence Keyes in 1919 as the apparent absence of the penis due to the penis being buried beneath the skin of the abdomen, thigh, or scrotum. Further research was done by Maurice Campbell in 1951, when he reported on the penis being buried beneath subcutaneous fat of the scrotum, perineum, hypogastrium, and thigh. Causes
Congenital
Congenital causes can include the maldevelopment of the penile shaft with a lack of attachments of the shaft skin to the penile shaft. While rare, it can include an abnormally large pubic fat pad and firm tissue that pulls the penis inward. Acquired
Obesity
While not every obese male has the buried penis condition, 87% of men that received surgical treatment for buried penis were reported to be obese. Significant overlying abdominal fat can also create an environment that encourages bacterial and fungal growth.
