The initial microbiome impacts the health and future development of premature infants. Methodological limitations have led to gaps in our understanding of the habitat range and subpopulation complexity of founding strains, as well as how different body sites support microbial growth. Here, we used metagenomics to reconstruct genomes of strains that colonized the skin, mouth and gut of two hospitalized premature infants during the first month of life. Seven bacterial populations, considered to be identical given whole-genome average nucleotide identity of >99...

Dental implants have been widely accepted as a predictable and reliable tool for dental reconstruction with the development of the economy. The design of implant-abutment connections has influence on mechanical properties and biological characteristics of implants. There are two types of implant-abutment connections, the external and the internal connections. Morse taper connection is one of the internal connections and its conical shape creates significant friction via the high propensity of parallelism between the two structures within the joint space...

BACKGROUND: Total gastrectomy for gastric cancer is associated with excessive weight loss and decreased calorie intake. Nutritional support using eicosapentaenoic acid modulates immune function and limits catabolism in patients with advanced cancer, but its impact in the perioperative period is unclear. METHODS: This was a randomized phase III clinical trial of addition of eicosapentaenoic acid-rich nutrition to a standard diet in patients having total gastrectomy for gastric cancer...

BACKGROUND: A principal reason for flap compromise in oral and maxillofacial head and neck surgery, and failure of a free flap transfer, is thrombosis of a drainage vein such as the internal jugular vein. This study characterized flap compromise caused by internal jugular vein thrombosis after a free flap transfer, and its management. PATIENTS AND METHODS: A retrospective clinical study was conducted of 306 consecutive microvascular free flaps performed for 305 patients with head and neck cancer from March 2003 to March 2013 at the Department of Oral and Maxillofacial Surgery at Beijing Stomatological Hospital, Capital Medical University...

The buccinator flap is currently one of the best techniques for the reconstruction of defects in the oral cavity and other sites. Reconstruction of the palate is a major challenge because of the functional consequences of the excision of lesions in this area. The main goal is to maintain separation between the mouth and the nose. We have done a cross-sectional retrospective descriptive study of a series of cases reconstruction of palatal defects with buccinator flap at the University Hospital Miguel Servet in Zaragoza during a six-year period and compared our results, morbidity, and mortality with those of published series...

Oncologic and traumatic defects of the maxilla can pose a challenge to patients, reconstructive surgeons, and maxillofacial prosthodontists in an attempt to provide satisfactory treatment. Oral-nasal and oral-antral fistulas are frequently treated with soft tissue flaps, osteocutaneous flaps, or a maxillofacial obturator. Often, surgical reconstruction is preferred for patient quality of life and definitive restoration. Surgical reconstruction also avoids the difficulties encountered with fabricating an obturator in an irradiated field with the often-resultant microstomia...

PURPOSE: The reconstruction of massive through-and-through oromandibular defects is still a challenge because no single adequate candidate for a donor site of vascularized bone and a large amount of soft tissue has yet been found. The aim of this study was to evaluate the feasibility and reconstructive efficacy of the combined fibula flap and anterolateral thigh (ALT) flap in tandem for the reconstruction of such defects. PATIENTS AND METHODS: We performed a retrospective case series of patients who had undergone reconstruction of through-and-through oromandibular defects with the combined fibula flap and ALT flap in tandem from January 2012 through December 2014 at the Second Xiangya Hospital...

Background Ameloblastomas are a rare tumor entity accounting for only 10% of all odontogenic tumors. They mostly originate from the mandible. Only a few cases are known to grow aggressively and to invade the orbit, nasal cavity, or even the brain. Patient and Methods/Case Report We present the case of a 57-year-old patient who was admitted with a huge tumor involving the nasal cavity, the left maxilla, and the anterior fossa. Histologic diagnosis was made by biopsy. A combined two-stage neurosurgical maxillofacial approach was planned...

Toxoplasma gondii, a protozoan found ubiquitously in mammals and birds, is the etiologic agent of toxoplasmosis, a disease causing substantial public health burden worldwide, including about 200,000 new cases of congenital toxoplasmosis each year. Clinical severity has been shown to vary across geographical regions, with South America exhibiting the highest burden. Unfortunately, the drivers of these heterogeneities are still poorly understood, and the geographical origin and historical spread of the pathogen worldwide are currently uncertain...

A 1-day-old male infant was referred to our department for evaluation of multiple malformations in his oral cavity. He was diagnosed duplication of the pituitary gland-plus syndrome with epignathus, cleft palate, duplication of the mandible, and a lobulated tongue. A thumb-sized mass lesion was visible on the hard palate. The duplicated mandible and lower lip was fused at the midline. The alveolar ridge was protruding through a wide-cleft soft palate involving the uvula. Further examination showed a lobulated tongue, which was seen behind the duplicated part of the mandible...

Trans Oral Robotic Surgery (TORS) is a prominent surgical approach for the resection of oropharyngeal tumors without division of the lip and mandible. Some defects following TORS are large and complex enough to benefit soft-tissue coverage. The pedicled temporalis muscle flap is a versatile and reliable flap and may be a valid option to reconstruct defects of the lateral pharyngeal wall and partial soft palate.

BACKGROUND: Reconstruction of maxillary defects following tumor extirpation is challenging because of combined aesthetic and functional roles of the maxilla. One-stage reconstruction combining osseous free flaps with immediate osseointegrated implants are becoming the standard for mandibular defects, and have similar potential for maxillary reconstruction. METHODS: A woman with maxillary Ewing sarcoma successfully treated at age 9 with neoadjuvant chemotherapy, right hemimaxillectomy, and obturator prosthetic reconstruction presented for definitive reconstruction, complaining of poor obturator fit, and hypernasality...
