Abstract:
Objective: To determine whether severe kyphosis is one of the risk factors of umbilical trichophytosis in elderly people. Patients and Methods: Four cases with umbilical trichophytosis in the last 3 years and all 143 patients who visited to our clinic during from April 2018 to March 2019 were included in this study. The relationship between the condition of umbilical region and kyphosis was investigated. As regards the levels of senile kyphosis, simple visual classification of the kyphosis method was used (Level 0-4). Results: All four cases with umbilical trichophytosis were elderly women aged ≥80 years, had severe kyphosis, skin overlaps, filthy umbilical region, and lumps of dirt in the umbilical region and had nail tinea. Only two cases had umbilical trichophytosis among 143 patients who visited our clinic during the 1 year study period, with incidence is of 1.4%/year. About 65.7%, 60%, and 37.1% of 35 patients with kyphosis with forward-bent posture had skin overlap, moist, and filthy umbilical regions, respectively. However, these symptoms were not found in patients without severe kyphosis. Conclusion: Severe kyphosis with forward-bent posture could be one of the risk factors of umbilical trichophytosis in elderly people.

Vertebral Column: Regions and Curvature
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
