Resolution of a periapical lesion in an autoimmune pancreatitis patient treated with long-term low-dose glucocorticoids: a case report Head Face Med. (IF 3.0) Pub Date : 2023-06-07 Sohar Flisfisch, Edgar Schäfer
Patients diagnosed with an autoimmune disease are often systemically medicated with glucocorticoids. Autoimmune pancreatitis (AIP) Type 1 is considered a rare autoimmune disease, which is very well responsive to glucocorticoids and hence can be treated optionally on a long-term basis using low dose of the drug. Apical lesions of root canal-treated teeth can be solved by retreatment of the preexisting

Mandibular reconstruction after excision of recurrent odontogenic keratocyst using a novel mandibular distraction osteogenesis method– a case report Head Face Med. (IF 3.0) Pub Date : 2023-06-02 Haiyun Lin, Xiaoxia Zhong, Nuo Zhou, Xuan-Ping Huang
Odontogenic keratocyst is one of the most common benign odontogenic neoplasms with a high recurrence rate. Its resection has the potential to lead to mandibular segmental defects. In this case report, we describe a patient with odontogenic keratocyst who underwent radical resection using a novel distraction osteogenesis (DO) method to reconstruct mandibular segmental defect. This case report describes

Study protocol for a multicenter, multinational, observational registry of epidemiology, treatment and outcome of patients with Robin sequence Head Face Med. (IF 3.0) Pub Date : 2023-05-20 Anna-Lisa Oechsle, Cornelia Wiechers, Veronique Abadie, Francois Abel, Corstiaan Breugem, Christian F. Poets
Robin sequence (RS) is a congenital condition characterized by micrognathia, glossoptosis and upper airway obstruction. Diagnosis and treatment are characterized by heterogeneity, resulting in a lack of uniformly collected data. We have set up a prospective, observational, multicenter, multinational registry aimed at obtaining routine clinical data from RS patients receiving different treatment approaches

Headache following vaccination against COVID-19 among healthcare workers with a history of COVID-19 infection: a cross-sectional study in Iran with a meta-analytic review of the literature Head Face Med. (IF 3.0) Pub Date : 2023-05-19 Somayeh Nasergivehchi, Mansoureh Togha, Elham Jafari, Mehrdad Sheikhvatan, Donya Shahamati
There is evidence of the occurrence of headache after vaccination against COVID-19. However, only a few studies have examined the headache characteristics and related determinants, especially among healthcare workers with a history of COVID-19 infection. We evaluated the incidence of headaches after injection of different types of COVID-19 vaccine to determine factors relating to the incidence of headache
