PURPOSE/OBJECTIVE:Recent studies suggest an increasing incidence of gram-negative bacteria and methicillin-resistant Staphylococcus aureus in dacryocystitis. Since patients are often treated empirically without culture data, a changing microbiologic profile will markedly affect the success of oral treatment. To provide current guidelines for the treatment of this common condition, we investigated the microbiology and antibiogram of dacryocystitis seen at our institution. METHODS:The charts of all patients presenting with acute and/or chronic dacryocystitis in University Hospital, Newark, from 2007 to 2015 were reviewed. Patient demographics, culture isolates, and in vitro antimicrobial susceptibility data were collected. Additional sensitivity data were obtained from the Sanford Guide to Antimicrobial Therapy. RESULTS:A total of 137 patients were included in the study. Of 205 samples collected, S. aureus was the most commonly isolated organism (46 of 156, 30%) followed by Pseudomonas species (19 of 156, 12%) and Propionibacterium acnes (15 of 156, 10%). Based on sensitivity data, the two oral antibiotics that would have been most effective in this population were levofloxacin and amoxicillin/clavulanate; however, even these antibiotics would have encountered at least one resistant organism in 16% and 32% of patients, and potentially in another 15% and 8% of patients, respectively. CONCLUSIONS:Given the broad range of causative organisms, routine treatment of dacryocystitis with any specific antibiotic may fail in up to one-third of patients. Obtaining a culture at the time empiric antibiotic treatment is initiated can prove extremely valuable when treating patients with dacryocystitis.

PURPOSE OF REVIEW/OBJECTIVE:The current study reviews the recent literature on pediatric orbital blowout fractures and provides guidelines on their management. RECENT FINDINGS/RESULTS:The most common problem among patients requiring surgical revision of a previously repaired orbital floor fracture is an improperly placed orbital floor implant, usually erroneously placed under the posterior bony ledge. Although the transconjunctival incision can be combined with a lateral canthotomy and cantholysis, excellent surgical exposure can be obtained without the need for these latter relaxing maneuvers. In surgically repaired pediatric orbital blowout fractures with preoperative diplopia (both trapdoor and nontrapdoor), approximately 85% of patients recover completely over time. Delayed orbital tissue atrophy may play a role in the development of late enophthalmos. SUMMARY/CONCLUSIONS:Most cases of pediatric orbital fracture can initially be followed conservatively to determine if disabling diplopia, when present, resolves without surgery. A notable exception is the trapdoor fracture, in which herniated tissue becomes entrapped by a recoiled bone fragment, causing marked or complete reduction in motility and/or an oculocardiac reflex; we recommend that these fractures be repaired within 24 h from the time of diagnosis. Enophthalmos resulting from an orbital floor fracture does not need to be prevented with early surgery. Enophthalmos can be allowed to develop over time to determine if it is noticeable, and then repair undertaken, if necessary, at that time. When surgery is indicated, a simple transconjunctival incision is preferred over a cutaneous incision, and care should be taken to insure that the implant is placed on the bony ledge at the posterior edge of the defect. Many children with blowout fractures will not require surgery, and those that do usually have excellent outcomes provided the recommendations are closely followed.

Shiitake mushroom dermatitis is a cutaneous reaction caused by the consumption of raw or undercooked shiitake mushrooms. Symptoms include linear erythematous eruptions with papules, papulovesicles or plaques, and severe pruritus. It is likely caused by lentinan, a heat-inactivated beta-glucan polysaccharide. Cases were initially reported in Japan but have now been documented in other Asian countries, North America, South America, and Europe, as this mushroom is now cultivated and consumed worldwide. Shiitake mushroom dermatitis may result from mushroom ingestion or from handling, which can result in an allergic contact dermatitis.

BACKGROUND:Traumatic hand injuries represent approximately 20% of emergency department visits; yet, access to emergency care remains inadequate. Recent surveys from several states report a wider availability of hand specialists providing elective care than emergency care. The authors aim to examine this phenomenon in the state of New Jersey and whether there is a national trend toward disproportionate availability between emergency and elective hand coverage. METHODS:A survey was conducted of all New Jersey hospitals, excepting university hospitals, in August 2014. To assess the availability of hand surgery coverage, the following questions were asked: (1) Does your hospital provide elective hand surgery? and (2) Is there a hand specialist/surgeon on call always, sometimes, or never? RESULTS:A total of 58 hospitals were called, with a 67.2% response rate (n = 39). The majority (87.2%) of hospitals offered elective hand surgery, whereas only 64.1% provided immediate 24/7 hand coverage. Only 38.5% of hospitals located in the same county as a level I trauma center provided 24/7 emergency hand care, whereas 76.9% of hospitals in counties without any level I trauma center did (P < .05). Cities with a higher poverty level were less likely to provide emergency coverage than cities with a lower poverty level (47.4% vs 80.0%; P < .05). CONCLUSIONS:There is a discrepancy between emergency and elective hand care in New Jersey. Similar findings across the nation suggest a concerning trend of limited access to emergency hand health care. Alternative systems that can appropriately triage and treat patients are warranted.
