Unexpected Opioid Responses in Infants: A Retrospective Case Series

Opioids are commonly prescribed for acute pain management. Complications such as nausea, vomiting, itch and constipation are not uncommon. Two unusual and unexpected complications that can arise in the acute setting are opioid-induced hyperalgesia (OIH) and acute opioid tolerance (AOT). The diagnostic challenges of these two entities are mainly attributed to their unpredictable onset and lack of strict diagnostic criteria. In the pediatric setting, additional confounding factors such as separation anxiety, hunger, thirst and poor verbal communication further complicate discerning between the two phenomena.

Tricuspid Valvulectomy in Drug Addicts with Native Valve Endocarditis: A Case Series

From Jan –2004 to Dec-2004, five patients were referred to the surgical department with a diagnosis of endocarditis refractory to medical therapy. Patients were all male, age ranging 16 years to 28 years with a mean of 22 years. All of the five patients had native valve endocarditis of the tricuspid valve with a history of drug addiction in common. Their presentations included, sepsis, failure and recurrent pulmonary embolism. Three of them had bacterial, while two had fungal infection which was proven after blood cultures. After resuscitation, stabilization and preoperative workup, tricuspid valvectomy was performed on these patients because of the destructive and irreparable nature of the native valve. Fortunately, all had uneventful recovery after surgery. Pre-operatively these patients were treated with antibiotics and antifungals, and continued thereafter for almost 4 to 6 weeks in the post-operative period. Postoperatively there was significant tricuspid regurgitation in a subset of patients who had a follow-up. The Left Ventricular (LV) function remained normal to moderate with a moderate pulmonary artery pressure. These patients were discharged on antibiotics and anti-failure medications as per the GDMT.

Homology Modelled Structure of Glutaredoxin 2 from Chlamydomonas reinhardtii

Different types of Glutaredoxins (GRXs) that play a major role in cellular anti-oxidative reactions have been studied for their structure and function from various organisms. Glutathione (GSH), an anti-oxidant with several medical benefits, binds to GRXs. This work has structurally characterized GRX2 from C. reinhardtii (CrGRX2) using biophysical, molecular modelling, and isothermal titration calorimetry (ITC) techniques. CrGRX2 adopts the classical GRX-Trx fold consisting of five β-strands surrounded by four α-helices that bind to GSH with moderate strength through a cysteine residue. The residues involved in the interaction closely match with those observed for E. coli and human counterparts, indicating that the cellular GSH-GRXs antioxidant system is highly conserved.

Erythematous, Hyperkeratotic Papule on the Left Distal Dorsal Aspect of the Middle Finger

Dermatofibroma (DF) is a common benign fibrosing lesion that can be found on any surface of the body, most often in the lower extremities. Dermatofibroma that arises on the digits, as in our present case, may be confused with other clinical entities or even malignant tumors, leading to unnecessarily aggressive treatment. To ensure proper diagnosis and treatment, dermatofibroma should be considered in the differential diagnosis of digital papules.

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
