Background: Fingertips are the most commonly injured anatomical structures in the upper extremity. The aim of this work is to present our experience in the management of fingertip injuries.

Methods: All patients with fingertip injuries managed by Plastic and Reconstructive Surgery Division of Hospital General “Dr Manuel Gea Gonzalez” in Mexico from July 2010 to June 2015 were included; their demographic characteristics were described, as well as patterns of injury and management.

Results: A total of 1,265 patients were included in the study, 75% were males. The mean age of presentation was 20.5 ± 16.46 years; the age group most commonly affected was younger than 15 years (46.7%). Right and left-sided injuries were almost equally prevalent (51 vs. 49%). The most commonly injured fingers were the third (27.2%), and second (25.8%). Eighty-seven percent of the patients presented with single-digit injuries. Fingertip amputations were the most common type of injury with 620 cases (49%), followed by simple fingertip lacerations (574 cases, 45%), and nail bed injuries in 71 cases (5.6%). Surgical management was necessary in 95.8% of the cases.

Conclusions: Fingertip injuries remain the most common reason for consultation in hand emergencies. A structured approach for their treatment is necessary to obtain the best clinical outcomes.

Background: With regards to the anatomical relationships in the mouth, oral squamous cell carcinoma can invade the maxilla or the mandible. According to the TNM system, tumours that invade through cortical bone are classified as T4a, stage IVA. Bone invasion by oral squamous cell carcinoma most often occurs in tumours close to the bone or in larger and more advanced tumours. It is considered an adverse prognostic factor and it is often a diagnostic and therapeutic problem. Destruction of the bone tissue is mediated by activated osteoclasts rather than directly by carcinoma. Tumor necrosis factors - receptor activator of NF-kB (RANK), receptor activator of NF-kB ligand (RANKL) and osteoprotegerin (OPG) - play an important role in osteoclastogenesis. According to histological point of view, there are three patterns of bone invasion - erosive, mixed and infiltrative. The most commonly used imaging techniques when evaluating bone invasion by oral squamous cell carcinoma include CT and MRI.

Purpose: This review is focused on the cellular and molecular mechanisms, histological patterns and detection methods of bone invasion caused by oral squamous cell carcinoma.

Epidermolysis bullosa (EB) is a rare inherited disease which is characterized by blisters on the skin and mucous membranes. Some forms of EB are associated with a risk of squamous cell carcinoma (SCC) development, which, unlike in the general population, is formed at a young age. SCC is the most common cause of death in patients with a dystrophic form. It is necessary to examine chronic and non-healing wounds for an increased risk of SCC. The basic treatment consists of surgical excision of the tumor site with a wide margin into healthy tissue. The surgical wound can be healed by secondary intention to prevent further trauma of the patient. The radicality of the excision is influenced by the location of the tumor. On the body, it is considerably limited by the surrounding tissue; on the limb, it is necessary to consider its amputation. In case of dissemination of the disease, it is important to approach patients individually and discuss other treatment options, including palliative care, within the national EB Center. The therapy is focused on pain treatment, remedial surgical dressings and psychological support with an emphasis on maintaining the quality of life.

Fungal infections are one of the most common diseases. Superficial mycoses affect the skin and visible mucous membranes. Deep mycoses include organ and systemic mycoses. The incidence of these diseases is increasing due to the use of broad-spectrum antibiotics, corticosteroids and cytostatics. Mycoses (yeasts and filamentous fungi) occur more often in patients with burns than in other patients; especially in patients with large and deep extent burns. In this case report, we are presenting a case of a 62-year-old patient hospitalized at the Department of Burns and Plastic Surgery, University Hospital Brno, with extensive deep burns (2nd-4th degree) covering 35% total body surface area (TBSA), predominantly in both lower limbs. During hospitalization, the patient was diagnosed with a combined bacterial and fungal infection for which targeted therapy was indicated.

Inhalation injury is a serious complication in patients with burns that dramatically increases their morbidity and mortality. These patients are always suspected of having inhalation injury with potential intoxication. We usually encounter carbon monoxide intoxication, but it is necessary to think about the possibility of poisoning by other combustion products. Cyanide intoxications are less common, but their diagnosis and treatment are more complicated. The diagnosis can only be based on the history, clinical findings, and indirect laboratory signs. Direct determination of plasma cyanide levels is not generally adopted in routine clinical practice. Nowadays, several specific antidotes with different mechanisms of action are available. There are no clear guidelines on the antidote of choice, as the evidence base is limited by a lack of randomised controlled trials in humans. In two mini case reports, we present our experience with the diagnosis and therapy of patients with suspected cyanide poisoning.

Lower and middle face defects resulting from gunshot wounds often cause severe functional and cosmetic deformities. The purpose of this case report is to refer to our experiences in the treatment of facial gunshot trauma associated with attempted suicide that resulted in a complex facial injury. The goal of the treatment of complex facial injuries is a proper reconstruction of the hard and soft tissue defects and sufficient rehabilitation of the relevant functions, such as speech, nutrition and appearance. A close cooperation of the maxillofacial and plastic surgeon is essential to achieve a satisfactory outcome.

Background: The Department of Plastic Surgery and Burns Treatment was established as a part of the newly created 2nd Department of Surgery of Charles University, Medical Faculty and the University Hospital in Hradec Králové in 1985. Through modest beginnings, activities of the Department expanded up to full coverage of specialized care in plastic surgery within the region with almost one million inhabitants.

Aim: In this article, the most important events of several historical phases related to almost four decades are described. The aspects of medical personnel, technological and space equipment are especially emphasized. The Department has always been working on the principles of interdisciplinary co-operation within the department itself and other departments within the hospital as well. Over the past 35 years, the Department of Plastic Surgery and Burns Treatment has been firmly entrenched in the spectrum of specialized activities of the University Hospital in Hradec Králové.

Background: Traumatic thumb loss is a serious injury affecting patient´s ability to work and participate in activities of daily life. The main goal for a plastic surgeon is to restore hand grip, often by microsurgical methods. However, patients should be informed of all effects associated with tissue harvesting. The aim of the study was to assess the impact on donor foot and gait cycle in patients who have undergone thumb reconstruction using twisted-toe technique modified by Kempný.

Material and methods: Twelve patients participated in the study: all suffered a thumb loss between the years 2003 and 2011 and the twisted-toe technique for thumb reconstruction was utilized. The changes in foot pressure distribution and lower extremity joint loading were evaluated.

Results: The differences in total maximal plantar pressure, pressure time integral, contact area, and maximum force between the affected and non-affected foot were statistically significant (P 0.1). No significant differences of temporal gait parameters between the affected and non-affected extremity were observed; however, statistically significant differences in kinetics parameters, frontal ankle and knee moments were detected.

Conclusion: Donor limb functionality and anatomical disability were assessed using pedobarography systems and 3D-gait analysis. The recorded differences in plantar pressure distribution (increased pressure in I., IV. and V. metatarsal areas) and overload of the medial compartment of the knee joint were the most significant findings. Therefore, wearing individually adapted shoe insoles as prevention of osteoarthrosis might be beneficial for patients after thumb reconstruction by a twisted-toe technique.

Introduction: A non-surgical procedure for the treatment of Dupuytrens disease is a palmar injection of Collagenase Clostridium Histolyticum to the recommended depth of “around 2-3 mm”. However, there is little supporting evidence from the literature to substantiate this. The aim of this study was to evaluate the “optimal depth” for injection of Collagenase Clostridium Histolyticum by ultrasonography for the treatment of Dupuytrens disease.

Material and methods: A total of 43 patients were enrolled in this study. We marked the collagenase injection point on the skin above the cord before injection. We then measured the distance from the surface of the skin to the middle of the cord by ultrasonography long axis imaging and defined this as the “optimal depth”.

Results: The average depth from the skin to the centre of the cord was 2.4 mm. The average distance from the surface of the skin to the proximal surface of the cord was 1.0 mm and the average thickness of the cord was 2.7 mm.

Conclusion: By precise measurement of individual cases utilising ultrasonography we were able to confirm that the recommendations for injection depth as provided by the supplier of Collagenase Clostridium Histolyticum (2-3 mm) were in agreement with our findings. However no objective guide was supplied as with regards to interindividual variability between patients and we suggest that the use of preliminary ultrasonography will likely provide improved outcomes.

The key point for microvascular reconstruction is to preserve patency of flap vessels. Despite great improvement in reconstruction success rates in the last 30 years, ischemic complications are still an undesirable event. The authors assessed recent as well as older literature and compared progression in perioperative pharmacology interventions in antithrombotic prevention.
