However, this increases the risk of endotracheal tube obstruction and pressure sores. Bacterial
Antibiotics improve outcomes in those with bacterial pneumonia. The first dose of antibiotics should be given as soon as possible. Increased use of antibiotics, however, may lead to the development of antimicrobial resistant strains of bacteria. Antibiotic choice depends initially on the characteristics of the person affected, such as age, underlying health, and the location the infection was acquired. Antibiotic use is also associated with side effects such as nausea, diarrhea, dizziness, taste distortion, or headaches. In the UK, treatment before culture results with amoxicillin is recommended as the first line for community-acquired pneumonia, with doxycycline or clarithromycin as alternatives. In North America, amoxicillin, doxycycline, and in some areas a macrolide (such as azithromycin or erythromycin) is the first-line outpatient treatment in adults. In children with mild or moderate symptoms, amoxicillin taken by mouth is the first line. The use of fluoroquinolones in uncomplicated cases is discouraged due to concerns about side-effects and generating resistance in light of there being no greater benefit.For those who require hospitalization and caught their pneumonia in the community the use of a β-lactam such as cephazolin plus macrolide such as azithromycin is recommended. A fluoroquinolone may replace azithromycin but is less preferred.
Hair loss may be present in the family, highlighting genetic causes. Causes
Causes of noncicatricial alopecia can be separated based on focal or diffuse hair loss:Diffuse:

Androgenetic alopecia: androgenic DHT leads to catagenic miniaturization of hair follicles. Diffuse alopecia areata: diffuse autoimmune destruction of hair follicles
Alopecia totalis: unknown but thought to be autoimmune
Telogen effluvium: emotional or physiologic stress
Anagen effluvium: cancer treatments such as radiation and alkylating agents
Dermatopathia pigmentosa reticularis: genetic autosomal dominant conditionFocal:

Alopecia areata: autoimmune destruction of hair follicles
Tinea capitis: fungal infection
Traction alopecia: pulling force applied to hair
Trichotillomania (Trichotillosis)

Diagnosis
There are a number of conditions that may cause non scarring hair loss and the first step is to determine the pattern: focal or diffuse. The next step is to identify if the hair loss is scarring or non scarring. A history and physical examination is necessary as this will provide clues to the ultimate diagnosis. It is essential to ask about the onset, observed pattern, hairstyles, family history, diet, and social history.Diffuse:

Androgenetic alopecia: history of gradual thinning of hair and characteristic pattern. Males start to lose hair in the front and temples while females lose hair at the top of the head
Diffuse alopecia areata: exclamation point hairs
Alopecia totalis: concomitant loss of facial and skull hair
Telogen effluvium: history of emotional or physiologic stress
Anagen effluvium: history cancer treatments such as radiation and alkylating agents
Dermatopathia pigmentosa reticularis: genetic autosomal dominant conditionFocal:

Alopecia areata: smooth and round lesions
Tinea capitis: black dots with broken hair strands, may see red, scaly lesions and swollen lymph nodes on the back of head.
