HOW TO PREVENT HAND INJURIES - REVIEW OF EPIDEMIOLOGICAL DATA IS THE FIRST STEP IN HEALTH CARE MANAGEMENT.

BACKGROUND: Hand injuries are common affecting all ages, genders, and geographic regions. They can result in long term disability and mortality, while they place a significant financial burden in society. Although, hand injuries can be prevented. Preventive strategies can be designed, but knowledge of injuries' epidemiological characteristics is required beforehand. METHODS: We performed a review of the current literature related to hand injuries to identify their incidence, patients' demographics, type, mode, and time of the injury. RESULTS: Hand injuries constitute 6.6% to 28.6% of all injuries presenting to the Emergency Department and 28% of injuries to the musculoskeletal system. They mainly affect young male labourers. Occupational and home accidents are the commonest injury modalities, while traffic road accidents constitute a significant reason for hand injuries as well. Lacerations account for most hand injuries, followed by crush injuries, fractures and amputations. Most occupational injuries occur in the beginning of the week and especially during the morning shift, while there has been identified an increase in the number of hand injuries during the summer months. CONCLUSIONS: Hand injuries are an important health problem with impact on patient's life and on the society. Although they can be prevented. Preventive strategies need to be addressed towards many directions and people's activities, since prevention will have an important impact on people's quality of life and society's well-being.

The broad spectrum of COVID-like patients initially negative at RT-PCR testing: a cohort study.

BACKGROUND: Patients that arrive in the emergency department (ED) with COVID-19-like syndromes testing negative at the first RT-PCR represent a clinical challenge because of the lack of evidence about their management available in the literature. Our first aim was to quantify the proportion of patients testing negative at the first RT-PCR performed in our Emergency Department (ED) that were confirmed as having COVID-19 at the end of hospitalization by clinical judgment or by any subsequent microbiological testing. Secondly, we wanted to identify which variables that were available in the first assessment (ED variables) would have been useful in predicting patients, who at the end of the hospital stay were confirmed as having COVID-19 (false-negative at the first RT-PCR). METHODS: We retrospectively collected data of 115 negative patients from2020, March 1st to 2020, May 15th. Three experts revised patients' charts collecting information on the whole hospital stay and defining patients as COVID-19 or NOT-COVID-19. We compared ED variables in the two groups by univariate analysis and logistic regression. RESULTS: We classified 66 patients as COVID-19 and identified the other 49 as having a differential diagnosis (NOT-COVID), with a concordance between the three experts of 0.77 (95% confidence interval (95%CI) 0.66- 0.73). Only 15% of patients tested positive to a subsequent RT-PCR test, accounting for 25% of the clinically suspected. Having fever (odds ratio (OR) 3.32, (95%CI 0.97-12.31), p = 0.06), showing a typical pattern at the first lung ultrasound (OR 6.09, (95%CI 0.87-54.65), p = 0.08) or computed tomography scan (OR 4.18, (95%CI 1.11-17.86), p = 0.04) were associated with a higher probability of having COVID-19. CONCLUSIONS: In patients admitted to ED with COVID-19 symptoms and negative RT-PCR a comprehensive clinical evaluation integrated with lung ultrasound and computed tomography could help to detect COVID-19 patients with a false negative RT-PCR result.

Experience of nail bed injuries at a tertiary hand trauma unit: a 12-month review and cost analysis.

The aim of this study was to analyse the management of nail bed injuries from a clinical and economic perspective. We carried out a retrospective analysis of nail bed injuries treated operatively at a tertiary Plastic Surgery Hand Trauma Unit during 2016. The National Schedule of Reference Costs (2015-2016) was used to estimate the costs of treating 630 patients. The most common mechanism was a crush injury in a door (33%). Fifty-five per cent of patients had an associated tuft fracture. The minimum cost per annum for patients treated for nail bed injuries in our unit was calculated to be £511,560 (€573,362; US$666,664). Many nail bed injuries are preventable and because they present a very high financial burden on the National Health Service, targeted prevention strategies should be considered. Level of evidence: IV.

Paraumbilical perforator flap for reconstruction of the external auditory meatus: A case report.

We herein present a technique of using the umbilical stalk for reconstruction of the external auditory meatus. A 49-year-old female presented with locally aggressive melanoma affecting her mastoid region. She underwent radical excision including the skin and soft tissues around the external ear with simultaneous lymph node clearance. The resultant defect measured 15 cm × 8 cm in diameter and was 2.5 cm deep. This was reconstructed with a similarly sized microvascular paraumbilical perforator flap that included the umbilical stalk. In the post-operative course there was complete flap survival but a prolonged wound dehiscence near the auditory meatus that required revision surgery. At 15-months follow-up, the patient was melanoma-free and the auditory meatus was patent. Hearing was also preserved. The umbilical stalk is one of the few skin covered tubed structures in the human body that may be used without major donor morbidity to "replace like with like," the auditory channel.

Incidence estimates of hand and upper extremity injuries in Italy.

OBJECTIVE: The purpose of this investigation is to estimate the incidence rates of upper extremity injuries and to give an overview of the most frequent diagnoses. MATERIALS AND METHODS: Two population databases were queried for all injuries in the upper extremities, the SINIACA-IDB (S-IDB: Emergency Department Injury Database in Italy) and the Hospital Discharge Register (HDR). The diagnoses codes of hand trauma were selected from both databases in order to estimate the national incidence rate. RESULTS: According to the S-IDB data of year 2011, total 1 479 510 ED attendances per year in Italy were estimated with an upper extremity injury (incidence rate: 2491 per 100 000 persons/year). About 880 816 Emergency Department (ED) attendances per year are due to hand injuries, while over 653 336 attendances per year concern arm injuries. The incidence rates are 1483 and 1100 per 100 000 person/year respectively. About 201 940 hospitalizations are observed in the HDR because of upper extremity injuries (incidence rate: 340 per 100 000 persons/year). Males have higher incidence rate (387 vs 280 per 100 000 persons per year). The trend in the incidence rates for the age group of inpatients shows two peaks: at age 12 (400 cases per 100 000 persons/year), and in the older age groups (700 cases per 100 000 persons/year).
