Hygiene-related Diseases Trachoma. Trachoma is the world’s leading cause of preventable blindness of infectious origin (1) . Caused by the bacterium Chlamydia trachomatis, trachoma is easily spread through direct personal contact, shared towels and cloths, and flies that have come in contact with the eyes or nose of an infected person.f left untreated, repeated trachoma infections can cause severe scarring of the inside of the eyelid and can cause the eyelashes to scratch the cornea (trichiasis). In addition to causing pain, trichiasis permanently damages the cornea and can lead to irreversible blindness.

- Endemic trachoma has been dramatically reduced by using community-wide oral azithromycin in a single dose or in repeated doses. Reinfection due to re-exposure is common among endemic areas. The World Health Organization has endorsed a 4 step program for control of trachoma in endemic areas. This program is known as SAFE: Surgery to correct eyelid deformities (eg, entropion and trichiaisis) that place patients at risk of blindness

Entropion When entropion occurs in both eyes, this is known as bilateral entropion.. Repeated cases of trachoma infection may cause scarring of the inner eyelid, which may cause entropion. In human cases, this condition is most common to people over 60 years of age.

Spontaneous cervical-mediastinal hematoma caused by hemorrhage into parathyroid adenoma: A clinical case Spontaneous cervical-mediastinal hematoma caused by extracapsular rupture of parathyroid gland occurs extremely rarely. The first occasion of an spontaneous cervical-mediastinal hematoma caused by hemorrhage into parathyroid adenoma was determined during autopsy.1 It indicates the extreme hazard of this condition.
