However, with early identification and prompt treatment, the prognosis is good, and there are usually no long-term consequences. Causes
The majority of neonatal cases (90%) result from applying a vacuum to the head at delivery (ventouse-assisted delivery). The vacuum assist ruptures the emissary veins (i.e., connections between dural sinus and scalp veins) leading to accumulation of blood under the aponeurosis of the scalp muscle and superficial to the periosteum.Additionally, subgaleal hematoma has a high frequency of occurrence of associated head trauma (40%), such as intracranial hemorrhage or skull fracture. The occurrence of these features does not correlate significantly with the severity of subgaleal hemorrhage. Diagnosis
Early recognition of this injury is crucial for survival. Infants who have experienced a difficult operative delivery or are suspected to have a SGH require ongoing monitoring including frequent vital signs (minimally every hour), and serial measurements of hematocrits and their occipital frontal circumference, which increases 1 cm with each 40 mL of blood deposited into the subgaleal space. Head imaging, using either CT or MRI, can be useful for differentiating subgaleal hemorrhage from other sources of cranial bleeding. Head ultrasound is useful for the diagnosis of SGH in the hands of an operator experienced in imaging the neonatal head and scalp, and is preferable to CT due to lack of ionizing radiation. Coagulation studies are required to detect coagulopathy that may be associated with the bleeding. Management
Management consists of vigilant observation over days to detect progression and, if required, manage complications (e.g.
All patients with syphilis should be tested for HIV infection. All cases of syphilis should be reported to public health authorities and public health departments can aid in partner notification, testing, and determining need for treatment.The treatment success is measured with a 4-fold drop in the nontreponemal antibody test. In early-stage syphilis drop should occur in 6–12 months. in late syphilis drop can take 12–24 months. Titers may decline more slowly in persons who have previously had syphilis.In people who cannot take penicillin it is uncertain if other antibiotic therapy is effective for treating neurosyphilis. == References ==
