Atrophic vaginitis is inflammation of the vagina as a result of tissue thinning due to not enough estrogen. Symptoms may include pain with sex, vaginal itchiness or dryness, and an urge to urinate or burning with urination. It generally does not resolve without ongoing treatment. Complications may include urinary tract infections.The lack of estrogen typically occurs following menopause. Other causes may include when breastfeeding or as a result of specific medications. Risk factors include smoking. Diagnosis is typically based on symptoms.Treatment is generally with estrogen cream applied to the vagina. Other measures that may help include vaginal lubricants. It is recommended that soaps and other irritants are avoided. About half of postmenopausal women are affected. Many however are not being treated. Women often report reduced enjoyment in sex as well as life generally. Signs and symptoms
After menopause the vaginal epithelium changes and becomes a few layers thick. Many of the signs and symptoms that accompany menopause occur in atrophic vaginitis. Genitourinary symptoms include

dryness
pain
itching
burning
soreness
pressure
white discharge
malodorous discharge due to infection
painful sexual intercourse
bleeding after intercourse
painful urination
blood in the urine
increased urinary frequency
incontinence
increased susceptibility to infections
decreased vaginal lubrication
urinary tract infections
painful urination
difficulty sitting
difficulty wiping

Diagnosis
Since women can have signs and symptoms that could be attributed to other causes, diagnosis is based upon the symptoms that cannot be better accounted for by another diagnosis. Lab tests usually do not provide information that will aid in diagnosing. A visual exam is useful.
Nezelof syndrome is an autosomal recessive congenital immunodeficiency condition due to underdevelopment of the thymus. The defect is a type of purine nucleoside phosphorylase deficiency with inactive phosphorylase, this results in an accumulation of deoxy-GTP which inhibits ribonucleotide reductase. Ribonucleotide reductase catalyzes the formation of deoxyribonucleotides from ribonucleotides, thus, DNA replication is inhibited. Symptoms and signs
This condition causes severe infections. it is characterized by elevated immunoglobulins that function poorly. Other symptoms are:
Bronchiectasis
Hepatosplenomegaly
Pyoderma
Emphysema
Diarrhea

Cause
Genetically speaking, Nezelof syndrome is autosomal recessive. the condition is thought to be a variation of severe combined immunodeficiency (SCID). However, the precise cause of Nezelof syndrome remains uncertain

Mechanism
In the mechanism of this condition, one first finds that the normal function of the thymus has it being important in T-cell development and release into the bodys blood circulation Hassals corpuscles absence in thymus(atrophy) has an effect on T-cells. Diagnosis
The diagnosis of Nezelof syndrome will indicate a deficiency of T-cells, additionally in ascertaining the condition the following is done:
Blood test (B-cells will be normal)
X-ray of thymus (atrophy present)

Differential diagnosis
The differential diagnosis for this condition consists of acquired immune deficiency syndrome and severe combined immunodeficiency syndrome

Treatment
In terms of treatment for individuals with Nezelof syndrome, which was first  characterized in 1964, includes the following(how effective bone marrow transplant is uncertain) :

Antimicrobial therapy
IV immunoglobulin
Bone marrow transplantation
Thymus transplantation
Thymus factors
