Insights
This case study details a six-year-old girl with recurrent respiratory infections, diagnosed with Anhydrotic/Hypohidrotic Ectodermal Dysplasia due to characteristic physical findings and reduced skin glands.
Area of Science:
- Dermatology
- Genetics
- Pediatrics
Background:
- Ectodermal dysplasias are a group of genetic disorders affecting ectodermal derivatives.
- Anhydrotic/Hypohidrotic Ectodermal Dysplasia (HED) is characterized by impaired development of hair, teeth, nails, and sweat glands.
Observation:
- A six-year-old girl presented with recurrent respiratory tract infections.
- Clinical features included facial hyperpigmentation, sparse hair, conical teeth with delayed eruption, prominent low-set ears, and toe abnormalities.
- Skin biopsy revealed reduced adenexal structures and eccrine glands in subcutaneous fat.
Findings:
- The patient's constellation of symptoms and biopsy results were consistent with Anhydrotic/Hypohidrotic Ectodermal Dysplasia.
- Reduced eccrine gland function likely contributed to the patient's susceptibility to infections.
Implications:
- Early diagnosis of ectodermal dysplasia is crucial for managing associated complications like infections.
- This case highlights the importance of recognizing diverse clinical presentations of HED in pediatric patients.
- Understanding the genetic basis of HED can inform genetic counseling and future therapeutic strategies.
Abstract:
We report a case of a six years age girl who presented to our out patients department with the history and findings suggestive of recurrent respiratory tract infections. She was also noticed to have: non homogeneous hyperpigmented patches on the face since three months of age, sparse hair on the scalp and eyebrows, conical peg like teeth and delayed dentition, prominent and low set ears, perpetually flexed third toe bilaterally. Axillary skin biopsy showed adenexal structures and eccrine glands in subcutaneous fat which were reduced in number. The diagnosis made was: Anhydrotic/Hypohidrotic type of ectodermal dysplasia.

Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
