Ancillary findings on high resolution CT chest associated with typical features of COVID-19 pneumonia (Observational descriptive study at a tertiary care hospital).

Objective: To determine the frequency of ancillary pulmonary signs and their relation to the severity of disease seen on high-resolution computed tomography of chest in patients of coronavirus disease-2019 pneumonia.

Methods: The observational descriptive study was conducted at the Armed Forces Institute of Radiology and Imaging, Rawalpindi, Pakistan, from March to July 2020, and included in place of comprised all coronavirus disease-2019 patients who were found positive on reverse transcription-polymerase chain reaction-and were referred to have high-resolution computed tomography of chest. Ancillary pulmonary findings in addition to typical features of coronavirus disease-2019 pneumonia were recorded.

Two Cases of Interrupted Inferior Vena Cava with Azygos / Hemiazygos Continuation.

Interrupted inferior vena cava (IVC) is a rare disease, occurring either in isolation or in association with asplenia or polysplenia syndromes. Infrahepatic part of the IVC is absent representing the failure of fusion of the vitelline and subcardinal embryological portions of the IVC. It is replaced by an enlarged azygos or hemiazygos vein continuing into the thorax, either into the superior vena cava or into the brachiocephalic veins.

Spontaneous Pneumomediastinum in COVID-19 Pneumonia: A Rare Occurence.

Spontaneous pneumomediastinum with COVID pneumonia is a rare occurrence with or without accompanying subcutaneous emphysema or pneumothorax. The aim of this study was to establish relation of this complication to severity of lung disease and its clinical outcome. The study was conducted for a period of seven months from April to October 2020 in the CT Department of Armed Forces Institute of Radiology and Imaging (AFIRI), Rawalpindi, Pakistan.

Diagnostic accuracy of cerebrospinal fluid lactate in confirmed cases of acute bacterial meningitis in children.

Objective: To determine the diagnostic accuracy of cerebrospinal fluid lactate level in confirmed cases of acute bacterial meningitis in children.

Methods: This cross sectional study was conducted in the Department of Paediatrics, King Edward Medical University/ Mayo Hospital, Lahore from January to December 2018. A total of 250 children, between two months - 12 years of age, of both the genders, with suspected acute bacterial meningitis were included by non-probability consecutive sampling.

Risk factors for candidaemia in neonates with sepsis in a tertiary care hospital in Pakistan.

Objective: To determine the risk factors for candidaemia in babies admitted to a tertiary care hospital with neonatal sepsis.

Methods: This nested case control study was conducted in the Neonatal Unit of the department of Paediatrics, King Edward Medical University/Mayo Hospital, Lahore, from January 2017 to June 2018. A total of 350 neonates having sepsis according to the clinical case definition were enrolled in this study by non-probability convenient sampling.

Exploiting Outage and Error Probability of Cooperative Incremental Relaying in Underwater Wireless Sensor Networks.

This paper embeds a bi-fold contribution for Underwater Wireless Sensor Networks (UWSNs); performance analysis of incremental relaying in terms of outage and error probability, and based on the analysis proposition of two new cooperative routing protocols. Subject to the first contribution, a three step procedure is carried out; a system model is presented, the number of available relays are determined, and based on cooperative incremental retransmission methodology, closed-form expressions for outage and error probability are derived. Subject to the second contribution, Adaptive Cooperation in Energy (ACE) efficient depth based routing and Enhanced-ACE (E-ACE) are presented.
