Macrolides are antimicrobial agents that can be used to treat a variety of infections. Allergic reactions to macrolides occur infrequently but can include minor to severe cutaneous reactions as well as systemic life-threatening reactions such as anaphylaxis. Most reports of allergic reactions occurred in patients without prior exposure to a macrolide. Cross-reactivity among macrolides may occur due to the similarities in their chemical structures; however, some published literature indicates that some patients can tolerate a different macrolide. Most published reports detailed an allergic reaction to erythromycin. Desensitization protocols to clarithromycin and azithromycin have been described in the literature. The purpose of this article is to summarize macrolide-associated allergic reactions reported in published literature. An extensive literature search was conducted to identify publications linking macrolides to hypersensitivity reactions.

Aminoglycosides are antimicrobial agents that are primarily used for infections caused by Gram-negative pathogens. The purpose of this article is to review the allergic reactions reported in the published literature to aminoglycoside antibiotics. A thorough PubMed search was conducted and excluded non-allergic adverse reactions to aminoglycosides. Allergic reactions to aminoglycosides occur infrequently, but can include cutaneous reactions as well as systemic reactions, including anaphylaxis. Of the evaluated aminoglycosides, gentamicin had the most reported allergic reactions, including the most reports of anaphylaxis, followed by tobramycin, and then amikacin. Most reports of allergic reactions occurred in patients who had a prior exposure to some dosage form of an aminoglycoside. Cross-reactivity among aminoglycosides is common and occurs due to the similarities in their chemical structures. Desensitization protocols to tobramycin have been described in the literature.

Hybrid Bearing

This work aims to design a magnetic suspension for an experiment to measure gravitys velocity. Such device must rotate two objects symmetrically with the greatest mass and largest radius as possible, at the speed of [Formula: see text], which means this device falls into the high-speed machines category. The guidelines and solutions proposed in this paper constitute a contribution to this class of engineering problems and were based on an extensive literature search, contacts with experts, the tutors and author’s experience, as well as on experimental results. The main solution proposed is a hybrid bearing that combines a radial passive magnetic bearing with an axial sliding bearing, here called MPS (Magnetic Passive and Sliding) bearing.

Tract Infections

Female urethral diverticular cancer is a very rare entity with only around 100 cases reported so far in literature and accounts for <1% of all malignancies. In this article, we present a 47-year-old African American female with repeated hospital visits for urinary retention, hematuria, and urinary tract infections. Initial computed tomography imaging and cystoscopy was unremarkable except for a distended urinary bladder. Subsequent magnetic resonance imaging and corresponding cystoscopy eventually indicated the presence of a urethral diverticulum. She underwent urethral diverticulectomy and was found to have a mass arising from urethral diverticulum extending to vaginal walls. Her biopsy was suggestive of invasive adenocarcinoma in advanced stages, for which she subsequently underwent a total pelvic exenteration. Next-generation sequencing of the tumor showed CDKN2A/B loss, MSI-stable, and low TMB, thereby ruling out the options for targeted therapies. Extensive literature search and expert opinions were sought for her case since no consensus exists regarding the optimal therapeutic approach due to the rarity of this tumor. A final decision was made to treat her with platinum-based chemotherapy. Different treatment approaches including neoadjuvant chemoradiation followed by surgery, surgery followed by adjuvant chemotherapy, and surgery followed by chemoradiation have been tried. Platinum-based chemotherapy has generally been preferred based on an extensive literature search. Multimodality treatment approach seems to be the current approach to management for advanced stages for better overall survival. This case illustrates the challenges faced in making diagnosis and treatment decisions due to the rarity of this type of tumor and lack of consensus in the treatment approach.

Despite the widespread use of tetracycline antibiotics since the late 1940s, tetracycline hypersensitivity reactions have rarely been described in the literature. A comprehensive PubMed search was performed, including allergic and serious adverse reactions attributed to the tetracyclines class of antibiotics. Of the evaluated tetracycline analogs, minocycline was attributed to the greatest overall number and severity of serious adverse events reported in the literature, with notable reactions primarily reported as respiratory and dermatologic in nature. Reactions to tetracycline have also been well described in the literature, and although dermatologic reactions are typically less severe in comparison with minocycline and doxycycline, various reports of anaphylactic reactions exist. Although doxycycline has been noted to have had the fewest reports of severe allergic reactions, rare descriptions of life-threatening reactions are still reported in the literature. Allergic reactions regarding tetracyclines are rare; however, adverse reaction type, severity, and frequency among different tetracycline analogs is somewhat variable. A consideration of hypersensitivity and adverse reaction incidence should be performed prior to the selection of individual tetracycline entities.

Extensive Literature Search

Species duration data for living benthic foraminifera derived from an extensive literature search have been compiled and analyzed to investigate rates and patterns of species origination. The same data subjected to taxonomic standardization through examination of many specimens lodged in museum collections indicate strikingly different, and more realistic, rates and patterns.Evolutionary generalizations based on data generated from the literature only are often unreliable and may be directly in opposition to reality. Extensive attempts at taxonomic standardization should be the norm in paleobiological investigations.

There are special considerations when performing cardiopulmonary bypass (CPB) on a patient with malaria. A 70-year-old female with a recent history of severe aortic stenosis was scheduled to undergo elective aortic valve replacement. One week prior to surgery, the patient developed shaking chills and fever, with a positive malaria smear. An extensive literature search was undertaken to determine the effect of CPB on a patient with active malaria, but no prior reference was found. One major concern was the lysis of red blood cells while on bypass. The surgery was performed uneventfully, following 2 weeks of treatment with primaquine phosphate.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are considered variants of a disease continuum that results in a life-threatening exfoliative mucocutaneous disease. These are categorised as type IV cell-mediated delayed hypersensitivity reactions, and antibiotics are often implicated as a cause. Penicillins and other beta-lactam antibiotics are known to cause both immediate and delayed hypersensitivity reactions. While immediate IgE-mediated cross-reactivity between penicillins and carbapenems is well studied, less information on the risk of type IV delayed cell-mediated cross-reactivity between the two is available. We present a case of meropenem-induced SJS in a patient with documented history of SJS from amoxicillin. There are few cases of cross-reactivity with carbapenems reported in the literature, but based on the potential for life-threatening reaction, it is likely prudent to avoid the use of any beta-lactams in a patient with a history of SJS, TEN or any other severe cutaneous adverse reactions to another beta-lactam antibiotic.
