AbstractA 12-year-old, female spayed crossbred dog was presented for traumatic injuries sustained after being hit by a car. The dog was non-ambulatory with a right-sided head tilt on presentation, neurological deficits and signs of external trauma centred on the head. A trauma computed tomography was performed which revealed an atlanto-occipital luxation with narrowing of the vertebral canal. This was treated successfully via closed reduction and confirmed with a repeat computed tomography scan. The dog recovered well following the atlanto-occipital luxation reduction, and was ambulatory the day after the reduction, and neurological signs resolved within 2 days.

This study was conducted to evaluate the computed tomography findings in patient with acute head injury and to emphasize the importance of computed tomography scan in head injury. One hundred consecutive patients presenting to the emergency department with head injury were evaluated by computed tomography scan of the head. Seventy five patients (75%) were male and twenty five (25%) were females. The age of the patients ranged from three to seventy years and the most affected age group was between thirty and forty (40%). The common causes of head injury were motor vehicle accident (70%), fall injury (25% ) and physical assault (5%). The most common computed tomographic findings were: cerebral contusions (52%), skull fractures (41%), intracerebral hematomas (24%), diffuse cerebral edema (23%), midline shift (18%), subdural hematomas (15%), subarachnoid hemorrhage (13%), diffuse axonal injury (8%), intraventricular hemorrhage (6%), extradural hemotomas (4%), pnemocephalus (2%) and normal scans were found in (5%). In conclusion, computed tomography is the mainstay in the imaging of head injury and helps in the patient management. DOI: http://dx.doi.org/10.3126/jcmsn.v7i1.5971 JCMSN 2011; 7(1): 36-39

Ischemic stroke following snakebite is rare. We report a case of a 55-year-old male who developed headache with expressive aphasia following a Russell’s viper bite. Computed tomography scan of the brain revealed infarcts in bilateral frontal lobes. The possible mechanisms for cerebral infarction in this scenario are discussed, which include disseminated intravascular coagulation, toxin-induced vasculitis, and endothelial damage. In viper bites, whenever there is any central nervous system manifestations or deficits, immediate computed tomography scan of the brain should be taken to delineate the underlying pathology, whether hemorrhagic or ischemic, as treatments differ in both situations. Although ischemic stroke is rare in viper bites, if the treatment is started early, the neurological deficits can be minimized.

Objective: To investigate the implication of a computed tomography scan for headache with non-localizing sign.Materials and methods: One hundred and thirty six patients with headache having non-localizing signs were included in this prospective study. Patients with age > 11 years, incomplete radiological or clinical data, recent/new onset headache, any immunosuppressive state, neurological deficits at the time of presentation, history of fever, trauma, any previous surgical intervention and any malignancy were excluded from the study.Results: Among the 136 patients, 73% were females and 27% were males with age range of 11- 76 years. Negative computed tomography scan was present in 91 (66.9 %) cases. Positive findings that significantly influenced the management were present in only 6 (4.4%) cases. Conclusion: Computed tomography in headache with non-localizing signs has a poor yield for a significant intracranial pathology. A careful and detailed assessment curtails the need for inadvertent imaging thus reducing the economic burden and health related hazards.Journal of Nepalgunj Medical College Vol.13(1) 2015: 2-4

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.
