Acute onset lung disease characterized by diffuse hyaline membrane formation followed by organization; Alternate/Historical Names. Adult respiratory distress syndrome (clinical term for disease with this pattern) Diagnostic Criteria. Diffuse alveolar damage (DAD) is a pattern that has many causes includin The characteristics of the GBM: diffuse thinning (thin basement membrane disease) (Figure 27), irregularities, multilayering and fragmentation (Alport's disease) (Figure 28), and diffuse thickening (diabetes mellitus) (figure 29) are key diagnosis features in ultrastructural pathology. Figura 27 How is HMD diagnosed? HMD is usually diagnosed by a combination of assessments, including: appearance, color, and breathing efforts (these signs indicate your baby's need for oxygen); x-rays of lungs: x-rays are electromagnetic energy used to produce images of bones and internal organs onto film. In HMD, they often show a unique ground glass appearance called a reticulogranular pattern

Infantile respiratory distress syndrome (IRDS), also called respiratory distress syndrome of newborn, or increasingly surfactant deficiency disorder (SDD), and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs Respiratory Distress Syndrome (Rds) 1. Respiratory distress syndrome (RDS) Mbbs.weebly.com 2. RDS = HMD RDS: Respiratory distress syndrome HMD: Hyaline membrane disease Hyaline disease of the lungs in the newborn infant has received considerable attention in pediatric and pathologic circles, but a careful search of the radiologic literature has failed to reveal similar studies of a radiographic nature. In the case to be reported here, two successive radiographs of the chest at intervals of several hours were obtained in a newborn infant who died after thirty. hyaline markings on Xray. He's thin because of increased work to breathe. He has a barrel‐chest, is pink (normal), breathing through pursed lips, and has wheezing. Remember, 90% of patients have both. Obstructive disease means a decreased FEV1/FVC Blue Bloater = Bronchitis Heavier in weight wit In some sections poorly defined paucicellular tubular structures reminiscent of seminiferous tubules composed of hyaline material are present; these probably represent obsolete seminiferous tubules. Focally, fibrosis is seen without definite tumour outlines. There is no significant inflammation. The rete testis is identified

Respiratory distress syndrome of newborns, also called hyaline membrane disease, a common complication in infants, especially in premature newborns, characterized by extremely laboured breathing, cyanosis (a bluish tinge to the skin or mucous membranes), and abnormally low levels of oxygen in the arterial blood.Before the advent of effective treatment, respiratory distress syndrome was. Data on pathologic changes of the 2019 novel coronavirus disease (COVID-19) are scarce. To gain knowledge about the pathology that may contribute to disease progression and fatality, we performed. THE ANTEMORTEM (clinical) diagnosis of hyaline membrane disease remains difficult because of the lack of a definitive test. This lack affects the assessment of ancillary diagnostic technics and the evaluation of treatment. Until a satisfactory testbecomes available,further effortmust be made to improve existing technics through comparison with.

Hyaline membrane disease, an older term and the synonym of RDS, refers to the microscopic appearance of smooth, homogeneous, eosinophilic membranes that line terminal bronchioles and alveolar ducts (, 23).

  1. Hyaline membrane disease: A respiratory disease of the newborn, especially the premature infant, in which a membrane composed of proteins and dead cells lines the alveoli (the tiny air sacs in the lung), making gas exchange difficult or impossible. The word hyaline comes from the Greek word hyalos meaning glass or transparent stone such as crystal

These cells form lobules that are surrounded by a hyaline or reticulin sheath. +/-Lymphocytes. Vascular component - large and small blood vessels. DDx: Dermal cylindroma. These two tumors are very closely related and overlap
  3. Diffuse lung disease (DLD) of infancy has multiple aetiologies and the spectrum of disease is substantially different from that seen in older children and adults. In many cases, a specific diagnosis renders a dire prognosis for the infant, with profound management implications. Two recently published series of DLD of infancy, collated from the archives of specialist centres, indicate that the.
  4. Perinatal mortality is the sum of still births and deaths under 7 days per 1000 total births. Stillbirths are the major component of perinatal mortality, twice as common as early neonatal deaths. More than 300 stillbirths occur annually in the Czech republic. The number of stillbirths remains largely unchanged in recent years while the neonatal.
  5. Periventricular leukomalacia means infarction of the periventricular white matter. The periventricular area is particularly vulnerable to hypoxic-ischemic injury because of high metabolic rate and watershed blood supply (boundary between the ventriculopetal and ventriculofugal arteries within the brain, the latter are poorly developed in premature infants) The lesion is common in preterm.

Diabetic nephropathy is the most common cause of ESRD and develops in 20% to 30% of patients with diabetes.

While patients typically develop albuminuria followed by overt proteinuria and glomerular filtration rate.
