Asa and Eli Hamby were born in 2014 in Georgia but died less than two days after birth due to heart failure. The twins were dicephalic parapagus  having two heads but being conjoined at the torso, arms and legs. They had separate spinal columns but one heart making postnatal operations impossible. Jadon and Anias McDonald, born in September 2015. Conjoined by the head. Successfully separated at Childrens Hospital of Montefiore Medical Center by James T. Goodrich in October 2016. Erin and Abby Delaney, born in Philadelphia, Pennsylvania on July 24, 2016. Conjoined by the head. They were successfully separated at Childrens Hospital of Philadelphia on June 16, 2017. Marieme and Ndeye Ndiaye, twin girls born in Senegal in 2017, living in Cardiff, UK in 2019. Safa and Marwa Bibi, twin girls born in Hayatabad, Pakistan on January 17, 2017, conjoined by the head. Successfully separated at Great Ormond Street Hospital in February 2019. Callie and Carter Torres, born January 30, 2017, in Houston Texas, from Blackfoot Idaho. They are Omphalo-Ischiopagus conjoined twins, attached by their pelvic area and sharing all organs from the belly button down with just one leg each. Yiğit and Derman Evrensel, twin boys born on June 21, 2018, Antalya, Turkey. They are craniopagus twins and were separated at Great Ormond Street Hospital in 2019 by the same surgeons that separated Safa and Marwa Bibi. Ervina and Prefina, born June 29, 2018, in the Central African Republic.
Due to this, even commercial flying may produce severe cases of barotraumas, although most of the cases are observed in high performance aircraft with lower pressurized cabins. Diagnosis
Most cases occur in scuba divers and fliers, and is easily diagnosed when presented to physicians immediately after exposure. On the other hand, the problem may remain undiagnosed when the history fails to relate the symptoms to exposure to environmental pressure changes or if the focus is on other etiologies. Grades
Weissman defined three grades of sinus barotraumas according to symptomatology. Grade I includes cases with mild transient sinus discomfort without changes visible on X-ray. Grade II is characterized by severe pain for up to 24 h, with some mucosal thickening on X-ray. Patients with grade III have severe pain lasting for more than 24 h and X-ray shows severe mucosal thickening or opacification of the affected sinus; epistaxis or subsequent sinusitis may be observed. Treatment
Mild cases of barotrauma are readily treated by topical decongestants and painkillers. In severe cases or cases resistant to local treatment, functional endoscopic sinus surgery is indicated in order to re-establish drainage and ventilation of the sinuses. This treatment has shown good results in aviators who have recurrent sinus barotrauma. Computer-aided surgery has re-established the drainage of affected sinuses, especially with regard to the sphenoid sinuses. When the sphenoids were entered endoscopically, mucosal petechia and hematoma were clearly seen. History
Sinus barotrauma or aerosinusitis has been known since the early development of aviation medicine.
