Summary
Postpartum headaches, especially with neurological symptoms, require urgent neuroimaging. A case highlights cerebral venous sinus thrombosis as a critical diagnosis in women with epidural-related dural puncture.
Area of Science:
- Neurology
- Obstetrics
- Radiology
Background:
- Postpartum headaches are common but require careful assessment.
- Epidural analgesia can lead to inadvertent dural puncture, a known cause of headaches.
Observation:
- A 35-year-old woman with pre-eclampsia experienced a headache post-epidural analgesia with dural puncture.
- Her headache worsened, becoming continuous and accompanied by neurological deficits including ataxic hemiparesis and convulsions.
Findings:
- Neuroimaging revealed cerebral venous sinus thrombosis (CVST).
- The patient was treated with anticoagulants and anticonvulsants.
Implications:
- This case underscores the importance of considering CVST in postpartum women with persistent headaches and neurological signs after dural puncture.
- Prompt diagnosis and management are crucial for favorable outcomes in postpartum CVST.

01:21Frequency-dependent Selection
24.2K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

02:05Gene Evolution - Fast or Slow?
8.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.

01:05Long-term Depression
33.4K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

01:29Nondisjunction
82.2K
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.

01:52Regression Toward the Mean
7.2K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...
