Ocular trauma with penetrating eye injury or globe rupture is an ophthalmic emergency. Immediate but gentle ocular assessment is mandatory to diagnose the extent of the injury. Imaging modalities are valuable in aiding diagnosis and management in open globe injury due to the difficulty of full eye assessment in the presence of multiple head and facial injuries. This report presents a case of an elderly man with ocular trauma of the left only seeing eye where computed tomography scan showed anterior globe rupture and the possibility of posterior globe rupture due to discontinuity of the posterior sclera. Primary repair and exploration of the left eye revealed no posterior globe rupture. Post-operative B-scan revealed a total retinal detachment with intact posterior globe. Vision of the left eye after pars planar vitrectomy and tamponade of the retina detachment with heavy silicone oil improved to 1/60. Computed tomography scan in ocular trauma has limitations especially in diagnosing retinal detachment and posterior globe rupture.

Background: Retinal detachment (RD) following ocular trauma often results in guarded visual prognosis and sometimes leads to loss of the eye. With the advent of microincisional vitrectomy surgery and the development of surgical techniques, the management of ocular trauma has been transformed. Case Presentation: A 34-year-old man sustained an open globe injury from fragmented glass at work. He received primary repair and another follow-up surgery 9 days later, including vitrectomy, silicone oil tamponade, and lensectomy for RD and traumatic cataract at another medical center. However, his retina was totally detached and completely curled up in a roll with choroid on display when he was seen by us 1 month later. He was managed with vigilant and patient peeling and unfolding of the retina using a 23-gauge forceps and silicone oil tamponade, and achieved anatomical success and preservation of his eye at 6-month follow-up. Conclusions: This report demonstrates that even in cases which appear to be hopeless at presentation, the surgeon’s perseverance and surgical technique can salvage an eye that may otherwise be phthisical. It also encourages retinal surgeons to use microincisional vitrectomy to manage severe traumatic RD.

Objective: The objective of study to assess the success of pars planavitrectomy with use of silicone Oil for internal tamponade in traumatic rhegmatogenous R D with severe PVR. Setting& Period: This study was carried out in department of Ophthalmology Military Hospital Rawalpindi. Material &Methods: Fifteen cases with severe proliferative vitreoretinopathy (PVR Grade C, according to up dated retina SocietyClassification of 1991) was included in study. All the patients had traumatic rhegmatogenous retinal detachment withhistory of blunt ocular trauma, without globe rupture, outcome of the treatment was assessed by post operativeanatomical and physiological success. Results: Anatomical success was encouraging in-spite of advance disease andtechnically difficult and complicated intra-ocular maneuvers.

A tracheal diverticulum is a type of paratracheal air cyst and is usually an incidental finding after a computed tomography scan of the neck and thorax. With an incidence between 1% and 4% in adults, tracheal diverticula are rare entities that can be symptomatic in certain cases. We present a case of a COVID-19 positive patient who presented to our hospital and was diagnosed with multiple tracheal diverticula during his hospitalization.

Abstract Background We diagnosed a clinical case of pulmonary infection involving Mycobacterium tuberculosis and Tropheryma whipplei in a patient with acute respiratory distress syndrome. The diagnosis was assisted by metagenomic next-generation sequencing of bronchoalveolar lavage fluid. Case presentation A 44-year-old Han Chinese inmate was transferred to the emergency department because of dry cough, chest tightness, and shortness of breath. The patient’s body temperature rose to 39.3 °C following empirical cephalosporin treatment for 1 week. The blood CD4+/CD8+ ratio was 0.7, suggesting immunodeficiency. Routine microbiological tests were performed, and tuberculosis interferon gamma release assays were positive. Mycobacterium tuberculosis polymerase chain reaction was also positive. Chest computed tomography scan revealed miliary nodules and ground-glass opacifications, which were in accordance with tuberculosis. To fully examine the etiology, we performed routine laboratory tests and metagenomic sequencing, the results of which indicated the presence of Mycobacterium tuberculosis and Tropheryma whipplei. We administered anti-tuberculosis regimen in combination with trimethoprim/sulfamethoxazole. The patient recovered, with chest computed tomography scan showing absorption of lesions. Conclusions Compared with traditional diagnostic methods such as culture and serology, metagenomic next-generation sequencing has the advantage of detecting a wide array of microorganisms in a single test and therefore can be used for clinical diagnosis of rare pathogens and microbial coinfections. It is particularly useful for immunocompromised patients as they are more prone to infection by opportunistic microorganisms.

The human respiratory tract has a complex airflow pattern. If any obstruction is present in the airways, it will change the airflow pattern and deposit particles inside the airways. This is the concern of breath quality (inspired air), and it is decreasing due to the unplanned production of material goods. This is a primary cause of respiratory illness (asthma, cancer, etc.). Therefore, it is important to identify the flow characteristics in the human airways and airways with a glomus tumour with particle deposition. A numerical diagnosis is presented with an asymmetric unsteady-state light breathing condition (10 l/min). An in vitro human respiratory tract model has been reconstructed using computed tomography scan techniques and an artificial glomus tumour developed 2 cm above a carina on the posterior wall of the trachea. The transient flow characteristics are numerically simulated with a realizable (low Reynolds number) k–ɛ turbulence model. The flow disturbance is captured around the tumour, which influenced the upstream and downstream of the flow. The flow velocity pattern, wall shear stress and probable area of inflammation (hotspot) due to suspended particle deposition are determined, which may assist doctors more effectively in aerosol therapy and prosthetics of human airways illness.

Bonebridge (BB) is the first active implantation system for bone conduction that is placed fully under the skin. Experience suggests that BB is characterized by low incidence of postoperative complications. This case report presents a rare case of a 16-year-old girl with incidence of emphysema occurring over the implant 1 year after operation. We performed a computed tomography scan that showed pockets of gas above the floating mass transducer so we provided the revision surgery and sealed the artificial opening with fat from the earlobe and fibrin glue. Since that time, no air has collected in the retroauricular area and the implant has been fully functional.
