Article Type: Case Series | First Published: November 07, 2019
Bisphosphonate medications are widely prescribed for the treatment of osteoporosis and cancer metastases to bone. However, these medications are among a list of agents which are implicated in medication related osteonecrosis of the jaw (MRONJ). A variety of non-surgical and surgical approaches are indicated in the treatment of this condition, depending on disease severity. This case series demonstrates the success of the mylohyoid flap in combination with platelet rich fibrin (PRF) in achieving closure of necrotic bony defects....

Rehabilitation of angle class III deformity concomitant with oligodontia with great functional, esthetic and social impairment for the patient needs a combined orthodontic-surgical treatment. To achieve secure, quick and stable dental and facial rehabilitation, backward planning with cone-beam CT navigation best supports the multidisciplinary approach. Here we show longtime stability of more than 5 years after thoroughly planning, bimaxillary osteotomy with an implant guided transpalatal distractor (Surgi-Tec All-in-One), conceptional extractions and alveolar augmentation in a male patient wit...

Pelvic hematomas can be a serious complication of vaginal delivery. They can be associated with significant morbidity related to blood loss, infection, surgery and blood product transfusion. Reported incidence varies from 1/300 to 1/1500. Operative vaginal delivery and episiotomy are among the most common risk factors associated with puerperal hematomas, but they may also occur in the absence of laceration of the surrounding tissue. They are classified as vulvar, vaginal, vulvovaginal or retroperitoneal. The majority of puerperal hematomas are vulvovaginal and can involve either branches of th...
Refractory Hyperemesis Gravidarum in a Patient with Type 1 Diabetes Treated with Laparoscopically Assisted Feeding Jejunostomy Tube Placement

Severe Hyperemesis gravidarum (HG) is a debilitating condition that affects less than 1% of pregnant women. Management of HG is further complicated in women with type 1 diabetes due to oscillations between hypo and hyperglycemia, often exacerbated by the presence of gastroparesis. We report a 25-year-old G1P0 with longstanding uncontrolled type 1 diabetes mellitus (HbA1C 10.5%), who presented to our service multiple times with hyperemesis and ketosis. On each of these admissions, she was diagnosed with starvation ketosis due to inability to tolerate any oral intake since the start of pregnancy...
A Review of Radiographic Imaging Findings of Ependymal Tumors
Maria Habib Hanna, MD, Bansal A, MD and Belani P, MD
Article Type: Review Article | First Published: October 24, 2019
Ependymomas are glial tumors that typically arise from the lining of the ventricles or the central canal of the spinal cord. The most common site of occurrence is within the posterior fossa. Subtypes of ependymomas include anaplastic ependymoma, myxopapillary ependymoma, and subependymoma. Its characteristic imaging features include findings of a heterogeneous mass with necrosis, calcifications, cystic changes, and hemorrhage. Treatment options includes partial resection with or without irradiation. Intracranial ependymomas are more commonly WHO Grade II and occur in both children and adults. ...

Liponeurocytoma is a very rare tumor of the nervous system, with only 63 reported cases, mainly in the cerebellum and ventricular system. The key-points for the diagnosis are the histological findings of neurocytic cells with lipidic accumulation, with positivity for S-100 and synaptophysin and negativity for IDH-1, and the MR finding of hyperintensity areas on T1Wi corresponding to fatty tissue within the tumor. This article reports a case of cerebellar liponeurocytoma presenting with acute ictal onset due to significant tumor hemorrhage and resulting in poor outcome with death, after urgent ...
A Revisit of Open Repair for Zenker's Diverticulum Compared to Endoscopic Repair
Ryan Marshall, MD, Gobind Gill, MD, Mohamad Babi, MD, Kirk Withrow, MD and Do-Yeon Cho, MD

The purpose of our study is to prove open repair (OR) for Zenker's diverticulum can result in similar lengths of stay in the hospital, and similar convalescent periods when compared to endoscopic repair (ER). Retrospective chart review was performed between 2013-2018 for those patients who had surgical repair of Zenker's diverticulum by two surgeons. After discussing all risks, benefits, and alternatives, patient made a decision whether to have ER vs OR of Zenker's diverticulum. These findings suggest OR and ER have a similar length of hospital stay although the operative time is longer with a...
Muscle Magnetic Resonance Imaging versus Clinical Function in Duchenne Muscular Dystrophy
Yingyin Liang, PhD, Jie Li, MD, Chen Yang, MD, Xue Xu, MD, Guidian Li, MD, Rongxing He, Dr and Cheng Zhang, PhD
Article Type: Original Article | First Published: October 17, 2019
Impairment in patients with Duchenne muscular dystrophy (DMD) has been evaluated primarily by muscle fiber microscopy examination. Pathologic examination is limited by the choice of muscle and the invasiveness of muscle biopsy. Magnetic resonance imaging (MRI) of the muscle is a noninvasive method of evaluating muscle preservation. To compare muscle MRI and clinical function in patients at different stages (from early to terminal stage) of DMD, and to evaluate the correlation between fatty infiltration grade on MRI and clinical functional scale....

Climate variables are one of the main drivers of dengue epidemics and the proliferation of their vectors. Significant relationships have been found between fluctuations in temperature, rainfall, and the incidence of dengue. The interaction between high levels of these variables significantly influences the increase in the incidence after at least one month of this event. The confirmed cases of dengue reported in the epidemiological bulletins of the Epidemiology General Directorate were collected. Seven states with the highest incidence in the Mexican Republic during the years 2016- 2018 throug...
