Summary
Dandy-Walker malformation with holocord syringomyelia is rare. A cystoperitoneal shunt effectively treated a pediatric case, resolving the syrinx and neurological symptoms.
Area of Science:
- Neuroscience
- Developmental Biology
- Pediatric Neurosurgery
Background:
- Dandy-Walker malformation (DWM) is a congenital brain defect impacting cerebellar development.
- Holocord syringomyelia is a rare complication of DWM, often associated with posterior fossa cyst herniation.
- Limited case reports exist, particularly from the pre-MRI era, highlighting treatment challenges.
Observation:
- An 11-year-old female presented with DWM and a holocord syrinx.
- The syrinx resulted from the posterior fossa cyst herniating through the foramen magnum.
- Initial shunt revision was unsuccessful.
Findings:
- A subsequent cystoperitoneal shunt procedure was performed.
- The syrinx significantly regressed following the cystoperitoneal shunt.
- Neurological symptoms improved substantially at 12-month follow-up.
Implications:
- Cystoperitoneal shunting may be an effective treatment for DWM-associated holocord syringomyelia.
- This case contributes to the limited literature on managing this rare condition.
- Further research is needed to optimize surgical strategies and long-term outcomes.

01:27Associative Learning
1.5K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

01:21Association Areas of the Cortex
9.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

15.8K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

2.8K
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

02:02Cis-regulatory Sequences
11.9K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

02:21Globular and Fibrous Proteins
47.3K
Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
