Pretibial hematomas – A real-world single-center study

Publisher Copyright: © 2022 The Author(s)We analyzed treatment, outcome, and risk factors for skin necrosis of 60 patients aged ≥65 years treated for a pretibial hematoma in the province of Kymenlaakso, Finland, between 2015 and 2019. Reviewing patients’ medical records revealed two cohorts with distinct trajectories in outcome. By comparing the cohorts, we were able to discover factors associated with the prognosis for generating skin necrosis and the need for operative treatment. Thirty-five (58.3%) patients healed without any management, and 25 (41.7%) patients were treated with hematoma evacuation, mostly for having generated skin necrosis (72%). Among operatively treated patients’ descriptions, such as “parchment skin” and “poor skin quality” were observed frequently (80%) in the medical records. This pathology, dermatoporosis, was statistically significant (p<0.0001) among patients with a complicated outcome of a pretibial hematoma. In addition to dermatoporosis, patients with hematoma evacuation were more fragile having a higher Charlson comorbidity index (p = 0.005), a greater need for a walking aid (p = 0.0002), and overall compromised independency (p = 0.033). Hospitalization and rehabilitation were prolonged in the operatively treated cohort, 6.4 days vs. 2 days, respectively. We recorded a delay in the diagnosis and hematoma evacuation (mean 6, range 0–51 days). In addition, six (10%) patients were misdiagnosed for having erysipelas or deep vein thrombosis indicating that pretibial hematomas are not recognized. Skin quality should be documented, and prompt surgical hematoma evacuation should be executed in fragile patients with dermatoporosis. This could prevent skin necrosis and the further need of wound care or surgical care, long hospitalization, and rehabilitation periods.Peer reviewe

Pretibial lacerations among elderly patients : A province-wide study from Kymenlaakso, Finland, 2015-2019

In this retrospective cohort study, we analysed treatment and outcomes among >= 65-year-old patients who experienced a traumatic pretibial laceration in the province of Kymenlaakso, Finland, between 2015 and 2019. We reviewed computerised medical records for 116 patients with a pretibial laceration, 107 of whom we analysed in further detail. Patients were traced from injury to healing, including rehabilitation periods in health care centres. As expected, the majority of patients were elderly women (67%). Most lacerations were superficial and small, explaining why treatment was mostly conservative. Only 11 (9.48%) patients were treated operatively with surgical debridement or a split-thickness skin graft. The number of overall complications in wounds was high, with a complication rate of 30.2%. Most complications were local wound infections. We found that wound healing took more than 3 months in 32% of patients. Thorough patient tracing revealed numerous follow-up visits and long rehabilitative hospitalisation periods, indicating a significant decline in patient independence and the excessive use of resources. Successful wound healing was eventually observed in 89.66% patients. Furthermore, no terminology regarding pretibial lacerations was found in patient records. This study indicates that pretibial lacerations remain poorly recognised and understood in Finland. (C) 2021 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Patient-related reasons for late surgery cancellations in a plastic and reconstructive surgery department

Late cancellations of scheduled operations cause direct and indirect costs for a hospital and economic and emotional stress for the patient. Previously, late cancellation rates for scheduled operations in plastic surgery have been shown to be attributable to patient-related causes in the majority of cases. In this retrospective study, we sought to examine specifically the patient-related reasons for the late cancellations in a plastic surgery operating theatre at Helsinki University Hospital in Finland from 2013 to 2014. We calculated latency between the date of decision for surgery and the scheduled operation day. In cases where the surgery was rescheduled and performed before 31 December 2015, the rescheduled waiting time latency was calculated. We aimed to improve our knowledge of the causes of late cancellations to further optimise the operating theatre efficiency and propose a strategic algorithm to avoid late cancellations During the study period, 327 (5.5%) of all the scheduled operations were recorded as late cancellations. Of these, 45.3% were because of patient-related issues. Acute infection, change in medical condition not noticed before and operation no longer necessary were by far the most common causes of cancellation, comprising 63.5%. Sixty-six per cent of patient-related cancelled operations were performed later, especially when the specific reason was patient's acute illness. Root-cause analysis shows that most of the underlying reasons for the cancellations can be attributed to a failure in communication. The majority of these cancellations were considered to be preventable, thus emphasising the importance of communication and skilful multi-professional planning of the operating theatre list. © 2018 The Author(s)Peer reviewe

Severe intimate partner violence affecting both young and elderly patients of both sexes

Background Intimate partner violence (IPV) affects 25-35 % of women and men in Western countries. Despite the high prevalence of IPV among trauma patients, very little is known about the associated injuries. Most previous studies excluded male victims and IPV is often limited to violence against women. Few reports on IPV among elderly patients exist. Methods We examined self-reports of IPV among patients at two major trauma centers of the Helsinki Central Hospital in Finland. Based on previous studies, we hypothesized that we would find the most severe injuries among young and middle-aged women. Results We identified 29 patients with a total of 105 injuries; patients typically presented with multiple injuries. Half of all patients required hospitalization or surgery. Contrary to previous studies, 17 % of our cohort were male, while 17 % of patients were 65 years or older. We found that 40 % of male victims presented with a New Injury Severity Score (NISS) over 15, indicating severe trauma. Two elderly patients presented with an NISS of 27, the highest in our study. Conclusions IPV leads to severe injury across all age groups among both male and female patients. The injury mechanism should be clearly defined for all trauma patients, keeping IPV in mind as a potential cause despite patient age or gender.Peer reviewe

Quemaduras por aire caliente en saunas: Lesiones fatales y poco frecuentes

Los baños de sauna son una actividad lúdica muy popular en Finlandia y es considerada segura incluso en pacientes embarazadas o con proble- mas cardiacos, pero la mezcla de alcohol y sauna puede ser peligrosa. En una sauna fi nlandesa normal la temperatura se encuentra entre los 80° y 90º. En todos los grupos de edad se produce una amplia variedad de quemaduras en relación con las saunas: las escaldaduras y quemaduras por contacto suman un 85%, mientras que las quemaduras por aire caliente, vapor o llamas son sólo el 15% restante. La deshidratación en los pacientes bajo la infl uencia del alcohol amplifi ca el riesgo de hipotensión que disminuye la circulación sanguínea en la piel. Esto incrementa el calentamiento de la piel, con un efecto más marcado en las partes externas y superiores expuestas al aire caliente. Estos pacientes requieren ingreso en la UCI de la unidad de quemados, reposición líquida siguiendo la fórmula de Parkland, diuresis forzada, corrección de la acidosis y mioglobinuria, puesto que presentan una rabdomiolisis signifi cativa. El mejor factor de supervivencia hasta ahora ha sido la P-CK en el segundo día. Es necesaria una exploración radiológica (TAC) para diagnosticar las condiciones subyacentes a la pérdida de consciencia. La zona necrótica se extiende a la grasa subcutánea e incluso a los músculos subyacentes. El nivel típico de desbridamiento es fascial, y en algunas áreas, también es necesario extirpar capas del músculo. Es importante conocer la extensión de este tipo de quemaduras para no subestimar la severidad de estas lesiones. INGLÉS: Sauna bathing is a popular recreational activity in Finland and is generally considered safe even for pregnant women and patients suffering from heart problems; but mixing alcohol with sauna bathing can be hazardous. In the normal Finnish recreational sauna the temperature is usually between 80 and 90 degrees C. A wide variety of burn injuries, in all age groups, are related to sauna bathing; scalds and contact burns account for over 85% while hot air, steam and flame burns for only 15%. Dehydration in patients under the influence of alcohol heightens the risk of hypotension which impairs skin blood circulation. This increased warming of the skin is an effect that is more marked on the outer and upper parts of the body exposed to hot air. Such patients require intensive care on admission: fluid replacement according to the Parkland formula, forced diuresis and immediate correction of acidosis and myoglobinuria. These patients have significant rhabdomyolysis on admission. The best predictor of survival is the creatine kinase level on the second post-injury day. CT scans are necessary to diagnose the underlying conditions of unconsciousness. The necrotic area extends to subcutaneous fat tissue and even to the underlying muscles. The level of excision is typically fascial and, in some areas, layers of the muscle must be removed. Owing to the popularity of sauna bathing throughout the world, it is important to know the extent of damage in this type of injury, in order not to underestimate the severity of such lesions

Aberrant expression of ALK and EZH2 in Merkel cell carcinoma

BACKGROUND: Distinct characteristic features categorize Merkel cell carcinoma (MCC) into two subgroups according to the Merkel cell polyomavirus infection. Many mutational studies on MCC have been carried out in recent years without identifying a prominent driver mutation. However, there is paucity reporting the expression of cancer genes at the RNA level in MCC tumors. In this study, we studied the RNA expression profiles of 26 MCC tumors, with a goal to identify prospective molecular targets that could improve the treatment strategies of MCC. METHODS: RNA expression of 50 cancer-related genes in 26 MCC tumors was analyzed by targeted amplicon based next-generation sequencing using the Ion Torrent technology and the expression compared with that of normal, non-cancerous skin samples. Sequencing data were processed using Torrent Suite Software. Expression profiles of MCV-negative and MCV-positive tumors were compared. Fluorescence in situ hybridization was performed to study ALK rearrangements and immunohistochemistry to study ALK expression in tumor tissue. RESULTS: ALK, CDKN2A, EZH2 and ERBB4 were overexpressed, and EGFR, ERBB2, PDGFRA and FGFR1 were underexpressed in MCC tumors compared to normal skin. In the MCV-negative tumors, MET, NOTCH1, FGFR3, and SMO were overexpressed and JAK3 and NPM1 were under-expressed compared to the MCV-positive tumors. CONCLUSIONS: High expression of ALK, CDKN2A and EZH2 was recorded in MCC tumors. No ALK fusion was seen by FISH analysis. Overexpression of EZH2 suggests its potential as a drug target in MCC.Peer reviewe

Merkel cell carcinoma: a population-based study on mortality and the association with other cancers

Few population-based epidemiological data are available on Merkel cell carcinoma (MCC), a rare lethal non-melanoma skin cancer. We analysed multiple-cause-of-death records to describe MCC mortality and trends and the association with other primary cancers. We reviewed all 6,713,059 death certificates in Italy (1995-2006) to identify those mentioning MCC. We evaluated the association with other primary cancers by calculating the ratio of observed to expected deaths, using a standardized mortality ratio (SMR)-like analysis. We also evaluated the geographic distribution of deaths. We identified 351 death certificates with the mention of MCC. The age-adjusted mortality was 0.031/100,000, with a significant trend of increase and a slight north-south gradient. There was a significant deficit for solid cancers (SMR = 0.15) and a non-significant excess for lymphohematopoietic malignancies (SMR = 1.62). There were significant excesses for chronic lymphocytic leukemia (SMR = 4.07) and Waldenstrom's macroglobulinemia (SMR = 27.2) and a non-significant excess for chronic myeloid leukemia (SMR = 5.12). The increase in MCC mortality reflects the incidence trend in the literature. The association with chronic lymphocytic leukemia confirms the importance of immunologic factors in MCC. Regarding Waldenstrom's macroglobulinemia, an association with MCC has never been reported

Sensitization and desensitization of burn patients as potential candidates for vascularized composite allotransplantation

Sensitization describes the acquired ability of the immune system to react to foreign human leukocyte antigens (HLA) by producing antibodies and developing memory cells. In the field of transplantation, recipient preformed HLA antibodies due to previous sensitization have been identified - beneath ABO incompatibility - as a major factor for acute graft rejection. Several reasons for sensitization have largely been studied, such as previous blood transfusions, pregnancies or former transplants. Recent studies indicate that the use of assist devices (e.g. ECMO) or cadaveric skin allotransplantation providing temporary coverage in burn patients may lead to additional sensitization. As vascularized composite allotransplantation (VCA) has become a rapidly advancing therapeutic option for reconstruction of complex tissue defects in burns, it seems even more important to become familiar with immunological principles and to be cautiously aware of both sources of sensitization and therapeutic concepts in burns avoiding sensitization. This may also include emergency VCAs in burn patients as potential strategy for early definitive reconstruction avoiding procedures triggering HLA antibody formation. We hereby provide an overview on current evidence in the field of pre- and peritrans-plant sensitization, followed by posttransplant strategies of desensitization and their potential impact on future treatments of burn patients.

Actualized lower body contouring surgery after bariatric surgery - a nationwide register-based study

Massive weight loss might lead to excess skin folds causing functional, physical, and psychosocial discomfort. Following bariatric procedures, an increasing number of patients are seeking lower body contouring surgery (LBCS). The proportion of bariatric patients who undergo LBCS is largely unknown. The aim of this current study was to analyse the incidence and realization of LBCS in bariatric patients in Finland. National retrospective register linkage study including all adult patients who received bariatric surgery in Finland during 1998-2016. The data were obtained from the Finnish national health registers maintained by the Finnish Institute for Health and Welfare. Altogether 1089 (14.1%) of 7703 bariatric patients underwent LBCS during the study period. The majority of the LBCS procedures were abdominoplasty (89%). Median latency between bariatric surgery and LBCS was 31 months. The patients with LBCS were younger (p < 0.001) and received sleeve gastrectomy (p < 0.001). We revealed an annual correlation between LBCS and bariatric procedures (r = 0.683). With a two-year latency between the bariatric and post-bariatric operations, the correlation co-efficiency was strong (r = 0.927). LBCS operations ranged from 5 to 215 per hospital district. Most LBCSs (97.3%) were performed in public hospitals, and some (41%) were performed in university hospitals. This study shows that only 14.1% of bariatric patients undergo LBCS. There is a correlation between bariatric procedures and succeeding plastic surgical reconstructive procedures
