Passive antibody transfer from pregnant women to their fetus are maximized after SARS-CoV-2 vaccination irrespective of prior infection.

Background: Pregnancy is associated with a higher risk of adverse symptoms and outcomes for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection for both mother and neonate. Antibodies can provide protection against SARS-CoV-2 infection and are induced in pregnant women after vaccination or infection. Passive transfer of these antibodies from mother to fetus may provide protection to the neonate against infection.

Safety, tolerability, and effectiveness of repetitive intravenous dihydroergotamine for refractory chronic migraine with cardiovascular risk factors: A retrospective study.

Background: Dihydroergotamine (DHE), like triptans, is contraindicated in patients with ischemic heart disease or coronary vasospasm. Its true safety, tolerability, and efficacy in patients with cardiovascular risk without ischemic heart disease or coronary vasospasm remain unclear.

Objectives: To assess the safety, tolerability, and effectiveness of repetitive intravenous DHE in patients with cardiovascular risk factors.

Real-world study of intranasal ketamine for use in patients with refractory chronic migraine: a retrospective analysis.

Introduction: Subanesthetic ketamine infusion has been used for managing refractory headache in inpatient or outpatient infusion settings. Intranasal ketamine may be an alternative option for outpatient care.

Methods: A retrospective study was conducted at a single tertiary headache center to assess the clinical effectiveness and tolerability of intranasal ketamine in patients with refractory chronic migraine.

Central Nervous System Involvement of Multiple Myeloma Presenting as Short-lasting Unilateral Neuralgiform Headache with Conjunctival Injection and Tearing: A Case Report.

Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) are part of the trigeminal autonomic cephalalgia (TAC) group of headache disorders. Attacks present with repeated, severe, sharp, stabbing, or throbbing pain. Patients may experience a single attack, recurrent attacks with pain-free interictal periods, or a sawtooth pattern background pain with superimposed stabs.

Lidocaine infusions for refractory chronic migraine: a retrospective analysis.

Introduction: Patients with refractory chronic migraine have poor quality of life. Intravenous infusions are indicated to rapidly 'break the cycle' of pain. Lidocaine infusions may be effective but evidence is limited.
