Review
The nail unit is the most commonly affected area in hand infections, which can be primary infection or superinfection complicating other nail or skin disorders. Trauma, mechanical or chemical, is usually the trigger enabling infiltration of infectious organisms. Artificial nails and nail polish are also a possible cause of bacterial infection, harboring microorganisms. In severe acute bacterial infection, surgical intervention is often needed to prevent morbidity and disability. Abscess should always be drained, but viral infection such as herpetic whitlow, may mimic an abscess and, in contrast, requires non-operative treatment; to prevent sequelae. A more conservative approach is also generally advisable in less severe bacterial infection, other viral infections and in subacute or chronic nail infection. The present review deals with acute, subacute and chronic bacterial and viral infections of the nail unit, with a focus on diagnostic and treatment options. LEVEL OF EVIDENCE: III, systematic review of level III studies.

Retronychia is a condition, first described in 1999, characterized by the embedding of the proximal nail plate into the proximal nail fold and the stacking of a multiple generations of nail plates beneath the proximal nail fold. The disease affects frequently the toenails and is associated with stress-relevant situations including repetitive trauma, ischemic etiologies, postpartum, and compartment syndrome. Predisposing factors including static disorder of the feet may be underestimated. The paucity of data regarding the predisposing factors is because existing studies are limited to small case reports, case series, and retrospective studies. The diagnosis is clinical, which could be challenging because retronychia can easily mimic other nail disorders with chronic paronychia. Since the first description, significant advances have been made regarding diagnostic criteria including ultrasonography. We performed a systematic review of the literature on retronychia from inception to April 2018 with an emphasis on the pathogenesis and new diagnostic and management trends.

BACKGROUND
Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) remain the frontline standard of care for patients with EGFR-mutant non-small cell lung cancer. An updated toxicity profile of EGFR-TKIs proves valuable in guiding clinical decision making.
OBJECTIVE
This study comprehensively assessed the risk of EGFR-TKI-related adverse events (AEs) involving different systems/organs.
METHODS
We systematically searched PubMed, Embase, Web of Science, and Cochrane library for phase III randomized controlled trials comparing EGFR-TKI monotherapy with placebo or chemotherapy in patients with non-small cell lung cancer. The odds ratio (OR) of all-grade and high-grade adverse events (AEs) including dermatologic, gastrointestinal, hematologic, hepatic, and respiratory events was pooled for a meta-analysis. Subgroup analyses based on the control arm (placebo or chemotherapy) and individual EGFR-TKIs (erlotinib, gefitinib, afatinib, dacomitinib, and osimertinib) were conducted.
RESULTS
Thirty-four randomized controlled trials comprising 15,887 patients were included. The pooled OR showed EGFR-TKIs were associated with a significantly increased risk of all-grade dermatologic AEs including paronychia, pruritus, rash, skin exfoliation, and skin fissures, gastrointestinal AEs including abdominal pain, diarrhea, dyspepsia, mouth ulceration, and stomatitis, hepatic AEs including elevated alanine aminotransferase and aspartate aminotransferase, and respiratory AEs including epistaxis, interstitial lung disease and rhinorrhea. Furthermore, a significantly increased risk of high-grade rash (OR 7.83, 95% confidence interval [CI] 5.11, 12.00), diarrhea (OR 2.10, 95% CI 1.44, 3.05), elevated alanine aminotransferase (OR 3.93, 95% CI 1.71, 9.03), elevated aspartate aminotransferase (OR 3.22, 95% CI 1.05, 9.92) and interstitial lung disease (OR 2.35, 95% CI 1.38, 4.01) was observed in patients receiving EGFR-TKIs. When stratified by individual EGFR-TKIs, gefitinib showed a significant association with all-grade and high-grade hepatotoxicity and interstitial lung disease.
CONCLUSIONS
Epidermal growth factor receptor tyrosine kinase inhibitors were associated with a significantly increased risk of various types of AEs. Clinicians should be vigilant about the risks of these EGFR-TKI-related AEs, particularly for severe hepatotoxicity and interstitial lung disease, to facilitate early detection and proper management.
