Piedraia hortae infection is a superficial fungal condition causing
dark, hard nodules on the hair shaft. Moreover, it mainly affects the
scalp and may lead to hair fragility without significant inflammation.
Primary adrenal insufficiency: a disorder where the adrenal glands
lose activity in the glomerular and fascicular layers. This prevents cortisol
and aldosterone production due to immune failure. It requires lifelong
hormonal treatment to regulate metabolism and blood pressure.
Primary adrenal insufficiency: a disorder where the adrenal glands
do not produce cortisol or aldosterone due to autoimmune damage or
infection. It causes fatigue, hypotension, and skin darkening. Treatment
consists of lifelong hormone replacement to stabilize metabolism and
blood pressure.
Progressive multifocal leukoencephalopathy is a serious brain
infection that destroys myelin in people with weakened immune
systems. This pathology, caused by the JC virus, triggers white
matter lesions that disrupt nerve transmission and cause permanent
neurological damage.
Prokaryotic cells are unicellular organisms without a nucleus,
containing circular DNA, ribosomes, and a cell wall, enabling
basic functions and rapid adaptation.
Pneumothorax refers to the inflammation of the membrane
surrounding the lungs, causing sharp pain when breathing
and shortness of breath. This condition can lead to a pleural
effusion or fluid buildup, requiring an accurate diagnosis of
the underlying cause.

Secondary adrenal insufficiency: a disorder caused by low ACTH
production in the pituitary gland. This reduces adrenal cortisol due to
pituitary tumors or abrupt steroid withdrawal. It causes fatigue and
weakness, requiring glucocorticoid treatment to restore hormonal and
metabolic balance.
Sjögren’s lacrimal gland is an autoimmune inflammation that
destroys the ability to produce tears, causing severe dry eye.
This pathology, common in women, causes irritation and a
gritty sensation in the eyes, requiring the use of artificial tears.
Sjögren’s skin dryness describes the skin dehydration caused by an
autoimmune attack on secretory glands. This condition, more
common in women, causes roughness, itching, and a weakened
skin barrier, accompanied by the lack of tears and saliva.
