RÉSUMÉ
The precise monitoring of the intrapleural pressures, necessitates the development of a specific instrumental approach to select the correct shape, dimensions and material to implement the sensing balloon which will be inserted into the pleural cavity. We demonstrate that a 10 cm diameter disk, printed with filaments of TPU (Thermoplastic polyurethane) with hardness 92A offers the best compromise in terms of static sensitivity (0.28 mV/cmHg) and dynamic frequency response (48 Hz).

BACKGROUND: The gold standard in the treatment of scaphoid pseudarthrosis is reduction, interposition of an iliac crest graft and stabilization with a headless bone (Herbert) screw, aiming to reduce the frequently observed humpback deformity. This study correlated the extent of humpback deformity after scaphoid reconstruction to clinical and radiological postoperative parameters. MATERIAL AND METHODS: Between 2008 and 2010 a total of 56 patients with scaphoid pseudarthrosis were surgically treated. Of the patients 34 could be included in this retrospective study. The average follow-up period was 7.3 months. The humpback deformity was evaluated by computed tomography (CT) scan performed along the long axis of the scaphoid. The disability of the arm, shoulder and hand (DASH) score, grip strength (Jamar), range of motion (RoM), Mayo wrist score (MWS) and other parameters were used to determine the clinical outcome. The patients were divided into two groups: 1) no or only slight humpback deformity (<25°), 2) severe humpback deformity (>45°). RESULTS: The RoM and DASH scores were slightly better for the first group. The second group had a significantly increased incidence of osteophyte formation (pâ¯< 0.05) and decreased RoM (-16°). CONCLUSION: It is postulated that the main disadvantage of an nonreduced humpback deformity is the increased occurrence of osteophyte formation in the dorsal aspect of the scaphoid. This can cause an impingement during extension and leads to a significant restriction of movement of the wrist. LEVEL OF EVIDENCE: III.

BACKGROUND: Osteoarthritis of the trapeziometacarpal joint is a common and painful affliction that can be diagnosed using conventional Xray imaging as well as arthroscopy and if necessary treated; however, the Xray classification often does not sufficiently demonstrate the cartilage damage found in arthroscopy. OBJECTIVE: The aim of the study was to evaluate the diagnostic accuracy of conventional Xray imaging compared to arthroscopy for osteoarthritis of the trapeziometacarpal joint. MATERIAL AND METHODS: The preoperative conventional Xray images of 23 patients were presented to 10 experienced hand surgeons who were blinded to the arthroscopy results. Their ratings were compared to the results found with arthroscopy. RESULTS: Of the patients 11 were found to have grade 4 cartilage lesions according to the Outerbridge classification, 8 grade 3 lesions, 4 grade 2 lesions and no grade 1 lesions. Overall, 43% (95% confidence interval, CI 37-49%) of the cartilage lesions were diagnosed correctly using conventional Xrays. For grade 4 lesions 73% (95% CI 65-81%) of the surgeons made the correct diagnosis, in the case of grade 3 lesions 38% (95% CI 27-49%) and in grade 2 lesions 13% (95% CI 3-23%). CONCLUSION: This study presents an arthroscopy classification system that is specific for osteoarthritis of the trapeziometacarpal joint and provides an additional method of assessment if the Xray grading of osteoarthritis according to Eaton and Littler is too unspecific. Arthroscopy can be used to safely differentiate the treatment-relevant stage and also includes treatment options.

BACKGROUND: Central skull-base osteomyelitis (CSBO) represents a life-threatening complication of external ear canal infection. Computed tomography (CT) and magnetic resonance imaging (MRI) play key roles in assessment of CSBO progression. METHODS: Twelve patients with CSBO were included in a retrospective clinical study. In total, 62 scans (30 CTs and 32 MRIs) were performed to evaluate the extent of inflammatory changes. The scans were read independently by two radiologists specialised in imaging of the head and neck. The regions under the skull base were specified using the online Anatomy Atlas of the skull base. To clarify the timeline, the time period was divided into four parts, and inflammatory changes in the skull-base regions were tracked. Data were statistically analysed. RESULTS: In early stages of the disease, CT scan detects inflammatory changes closely related to the stylomastoid foramen and medially to the posterior belly of the digastric muscle, changes which have been proved to be crucial for the diagnosis of CSBO. Later the infection spreads to the contralateral side causing demineralisation of the bones. CONCLUSION: Imaging methods play a crucial role not only in establishing the diagnosis, but also in anticipating the direction of infection spread underneath the skull base.

INTRODUCTION: The partial aponeurectomy for treatment of Dupuytren's contracture represents the gold standard for treatment of Dupuytren's contracture. In selected cases, the alternative is the percutaneous needle fasciotomy (PNF). MATERIALS AND METHODS: Between 2008 and 2018, 80 rays in 64 patients were treated using PNF. 53 patients (68 rays) were reviewed with a mean follow-up of 31 months. RESULTS: The recurrence rate was 18.9%. 49 patients with 62 rays had a totally free extension intra-operatively (92.4%). There were no complications. Only one patient reported a transient dysesthesia (1.8%) in the zone of operation. 86% of all patients would undergo the treatment again, if necessary. Patients were able to return to their job in an average of 5.5 days. CONCLUSIONS: PNF is reliable and relatively simple to perform compared to partial aponeurectomy. Therefore, the PNF could be seen as a serious alternative for selected cases.

The paper examines the development and testing of an electro-pneumatic device for wound healing therapy after surgery in the neck area. The device generates air pressure values in a miniaturized cuff using electronic circuitry to drive an electro-valve and air compressor. The device works in two distinct modes: continuous pressure mode and pulsating pressure mode. The pressure value setting can vary from 3 to 11 mmHg, and the pulsating pressure mode's operating frequency range is approximately 0.1 to 0.3 Hz. Laboratory measurements were conducted to evaluate the device's correct functioning in both continuous and pulsating pressure modes. A four-day prospective study with animals (n = 10) was also conducted to evaluate neck wound healing therapy using the electro-pneumatic device. Out of the twelve histological parameters analysed to reveal the differences between the experimental and control wounds, only one demonstrated a significant difference. Out of the ten animals treated with the device, three showed a significant difference in terms of benefit after therapy. We can therefore conclude that the device potentially improves the wound healing process in the neck area if the pre-set air pressure value does not exceed 8 mmHg.

OBJECTIVE: Description of newborn with early prenatal diagnosis of sacrococcygeal teratomia. Desing: Case report. SETTING: Department of Obstetrics and Gynecology, 2nd Faculty of Medicine and Faculty Hospital Motol Prague. CASE REPORT: In this case report a term neonate with a massive sacrococcygeal teratoma was delivered by a cesarean section (approach by Geppert) with an intrapartal relieving punction of the tumor. It was a type II SCT with both pelvic end extracorporal component with a size of 60×35 centimeters. The tumor was completely resected during the first day of life and was followed by a normal function of lower extremities, normal bowel function and only transitional urinary tract symptoms. CONCLUSION: A sacrococcygeal teratoma (SCT) is the most common congenital tumor in newborns with reported incidence of 1:35000-40000 live births affecting more frequently females (4:1). This germinal tumor is either benign (mature) or malignant (immature), mature types are more common in neonates. A SCT is usually diagnosed by prenatal ultrasound, magnetic resonance is performed to characterize its size and content, type of tumor (type I-IV Altman classification) and relation to surrounding tissues. Preemptive early delivery by cesarean section is recommended when the tumor exceeds the diameter of 5 centimeters to avoid complications during vaginal delivery (rupture, bleeding etc.). The primary treatment of SCT is an early surgical resection with a complete resection of the coccyx („en bloc“ resection), malignant tumors are indicated for adjuvant chemotherapy. Long term complications can be urinary tract or bowel dysfunctions, lower extremity muscle weakness or paralysis and recurrence of the tumor with potential malignancy.

OBJECTIVE: Description of rare diagnosis of patent urachus. DESIGN: Case report. SETTING: Department of Obstetrics and Gynecology, 2nd Faculty of Medicine and Faculty Hospital Motol Prague. CASE REPORT: Patent urachus is a rare diagnosis, which in this case was detected prenatally by ultrasound. Involution of the urachus is not fully completed upon birth, therefore in cases of small persisting communication between the urinary bladder and the umbilicus conservative approach and waiting for spontaneous closure is usually chosen. In our case surgery treatment has chosen as a prevention of urinary infection because of patent urachus manifested as a wide communication. CONCLUSION: This congenital defect usually manifests itself early after birth as a visible structural anomaly of the umbilicus and/or as urine leakage in the umbilicus opening area. It is important to keep in mind that urachus irregularities may be accompanied by other urinary system defects. Every child presenting with such an anomaly should therefore be thoroughly examined. If the procedure is performed by an experienced surgical team postoperative complications are uncommon and overall long-term prognosis for patients is excellent.

INTRODUCTION: The surgical procedures due to aortoiliac aneurysm (AAA) represent the most demanding procedures in conventional vascular surgery. This is due, among other things, to the relatively frequent systemic and surgical complications in polymorbid and often urgently operated patients. Surgical and vascular complications after resections of aortoiliac aneurysms are relatively common, and reintervention due to these complications is reported to range around 14%. METHOD: Retrospective clinical study of a group of patients undergoing surgical management for aortoiliac aneurysms in the period from 1 January 2010 to 31 December 2017 at the Department of Vascular and Plastic Surgery of Pardubice Hospital NPK. RESULTS: In a group of 240 patients (205 males, 35 females), mortality reached a total of 10.4%, with mortality in elective cases 3.4% and 31.1% in urgent procedures (37.5% in AAA rupture). Overall, in the elective group, we recorded a total of 29 (16.2%) surgical and/or vascular complications with the necessity of 16 (8.9%) surgical, endovascular or combined interventions. In the emergency group, these complications were recorded 30 times (49%) with the need for intervention in 19 cases (31.1% of emergency procedures). CONCLUSION: Open surgical procedures on AAA are accompanied by a high incidence of systemic and surgical and/or vascular complications. These patients therefore require high attention and quality of intensive care in the postoperative period, focusing on early diagnosis and subsequent treatment of these complications. Key words: aortoiliac aneurysm surgical complications - bleeding limb ischemia abdominal compartment syndrome.

This study describes the meta-analysis and kinetic modelling of gene expression control by sigma factor SigA of Bacillus subtilis during germination and outgrowth based on microarray data from 14 time points. The analysis computationally models the direct interaction among SigA, SigA-controlled sigma factor genes (sigM, sigH, sigD, sigX), and their target genes. Of the >800 known genes in the SigA regulon, as extracted from databases, 311 genes were analysed, and 190 were confirmed by the kinetic model as being controlled by SigA. For the remaining genes, alternative regulators satisfying kinetic constraints were suggested. The kinetic analysis suggested another 214 genes as potential SigA targets. The modelling was able to (i) create a particular SigA-controlled gene expression network that is active under the conditions for which the expression time series was obtained, and where SigA is the dominant regulator, (ii) suggest new potential SigA target genes, and (iii) find other possible regulators of a given gene or suggest a new mechanism of its control by identifying a matching profile of unknown regulator(s). Selected predicted regulatory interactions were experimentally tested, thus validating the model.

INTRODUCTION: Vascular surgery through a groin incision may be associated with severe wound healing disorders in this sensitive area. There are many options to reconstruct the defect surgically. The choice of surgical reconstruction depends mainly on the individual status of vasculature, which is most often compromised in these patients. There are random pattern flaps, as well as perforator, pedicled flaps or microvascular flaps to choose from. AIM: We give an overview of plastic surgical solutions for groin defects, with a special focus on complex wounds after vascular surgical complications. We discuss advantages and disadvantages of different flaps with two case reports and also show alternatives. PATIENTS AND METHODS: We demonstrate in two cases how the reconstruction of the groin defect was planned, taking into account the vascular status, and why we chose an innovative and seldom-used option in each case. RESULTS: The selected flaps, a pedicled fasciocutaneous ALT propeller flap and a perforator-based, pedicled abdominal advancement flap reconstructed the defects successfully. DISCUSSION: The surgical therapy for the reconstruction of groin defects should be chosen according to the individual vascular status to ensure safe and reliable blood supply. To guarantee the best possible reconstruction and avoid postoperative healing disorders and infections, less common flaps should also be considered.

Introduction: Free flap transplants for soft tissue reconstruction in the lower extremity are associated with a higher rate of complications compared with other areas. Mobilisation and the resulting hydrostatic pressure put strain on the flaps. In general, these effects are countered by slowly increasing hydrostatic pressure with the leg being compressed by elastic bandages. These postoperative regimes are also called dangling procedures or "flap training", but are not scientifically validated and therefore there is no consensus or guideline leading to a standard treatment regime. The goal of our study was to present an overview of currently performed regimes. Material and Methods: We conducted an email survey by sending a questionnaire to departments for plastic and reconstructive surgery in Germany, Austria and Switzerland, which perform free flap transplantations in the lower extremity. The questionnaire ascertained the starting point and the frequency of the dangling procedures, the introduction of weight-bearing on the operated extremity and the incidence of complications occurring during mobilisation. Results: We included 32 departments and compared them by the number of free flap transplantations performed per year. We found a wide variation between the postoperative treatment regimes. In most departments, flap training is started between the 3rd and 7th day after surgery and lasts between 5 and 15 min. The intervals with which flap training intensity is increased are inhomogeneous as well. The time until full weight-bearing is exerted on the operated extremity ranges from day 5 to week 3 postoperatively. Complications due to flap training were reported by one third of the participating departments. Conclusion: Elastic compression and patient mobilisation after free flap procedures in the lower extremity are considered to be very important in reducing complications and in protecting the flap from edema and volume overload. This article demonstrates that there is a wide variety in flap training regimes. It aims to help readers evaluate their own regimes and provides guidance for an individualised patient-oriented regime.

BACKGROUND AND PURPOSE: Despite a recent resurgence, intravoxel incoherent motion MRI faces practical challenges, including limited SNR and demanding acquisition and postprocessing requirements. A simplified approach using linear fitting of a subset of higher b-values has seen success in other organ systems. We sought to validate this method for evaluation of brain pathology by comparing perfusion measurements using simplified linear fitting to conventional biexponential fitting. MATERIALS AND METHODS: Forty-nine patients with gliomas and 17 with acute strokes underwent 3T MRI, including DWI with 16 b-values (range, 0-900 s/mm2). Conventional intravoxel incoherent motion was performed using nonlinear fitting of the standard biexponential equation. Simplified intravoxel incoherent motion was performed using linear fitting of the log-normalized signal curves for subsets of b-values >200 s/mm2. Comparisons between ROIs (tumors, strokes, contralateral brain) and between models (biexponential and simplified linear) were performed by using 2-way ANOVA. The root mean square error and coefficient of determination (R2) were computed for the simplified model, with biexponential fitting as the reference standard. RESULTS: Perfusion maps using simplified linear fitting were qualitatively similar to conventional biexponential fitting. The perfusion fraction was elevated in high-grade (n = 33) compared to low-grade (n = 16) gliomas and was reduced in strokes compared to the contralateral brain (P < .001 for both main effects). Decreasing the number of b-values used for linear fitting resulted in reduced accuracy (higher root mean square error and lower R2) compared with full biexponential fitting. CONCLUSIONS: Intravoxel incoherent motion perfusion imaging of common brain pathology can be performed by using simplified linear fitting, with preservation of clinically relevant perfusion information.

Non-invasive blood pressure measurement (NIBP) is one of the most discussed topic in cardiovascular medicine. Currently continuous measurement of blood pressure is possible by invasive methods, which makes the measurement impractical for Doctors and uncomfortable for the patients. It is possible to use special devices to measure blood pressure noninvasively continuously but there are still some problems with long time monitoring and comfort for patient. Physiologically there is connection between electrical and mechanical heart functions, propagation of pulse wave and blood pressure value. Our paper investigates various methods for the evaluation of NIPB from pulse transit time. We analyse real signals which we obtained during surgical interventions in Hospital, with invasive measurements of blood pressure waves, and non-invasive measurements of pulse waves and ECG signal.

MR imaging is currently regarded as a pivotal technique for the assessment of a variety of musculoskeletal conditions. Diffusion-weighted MR imaging (DWI) is a relatively recent sequence that provides information on the degree of cellularity of lesions. Apparent diffusion coefficient (ADC) value provides information on the movement of water molecules outside the cells. The literature contains many studies that have evaluated the role of DWI in musculoskeletal diseases. However, to date they yielded conflicting results on the use and the diagnostic capabilities of DWI in the area of musculoskeletal diseases. However, many of them have showed that DWI is a useful technique for the evaluation of the extent of the disease in a subset of musculoskeletal cancers. In terms of tissue characterization, DWI may be an adjunct to the more conventional MR imaging techniques but should be interpreted along with the signal of the lesion as observed on conventional sequences, especially in musculoskeletal cancers. Regarding the monitoring of response to therapy in cancer or inflammatory disease, the use of ADC value may represent a more reliable additional tool but must be compared to the initial ADC value of the lesions along with the knowledge of the actual therapy.

INTRODUCTION: Infection of the prosthetic graft represents one of the biggest challenges for practising vascular surgeons. The patient is jeopardized with possible future limb loss or, in the most serious cases, even death due to this complication. The incidence in the infrainguinal area amounts to a maximum of 6% of all arterial surgical procedures. MATERIAL AND METHODS: Between January 2010 and December 2011, the authors performed a total of 689 vascular surgical reconstructions, of which 311 were performed in the infrainguinal area where 7 cases (2.25%) of graft infection occurred. RESULTS: None of the patients died or lost a limb due to this complication. Two patients with an infected infrainguinal prosthetic graft were successfully treated with vacuum-assisted closure (VAC) system. CONCLUSION: The prosthetic vascular graft infection is the most feared complication in vascular surgery. The generally recognized principles of the traditional surgical approach are well-known and widely accepted. However, in selected cases of infrainguinal vascular prosthetic infection, both the affected limb and the patent graft may be saved and successfully treated with the use of vacuum-assisted closure.

INTRODUCTION: Periproctal abscess is a routine diagnosis of everyday surgical practice. Fournièr's gangrene with progress to the sepsis is one of the most serious complication of this disease. CASE REPORT: The authors present a case review of fulminant surgical infection run as a Fournièr's gangrene and a necrotizig fasciitis of a right lower limb and body with the progress of severe septic status, which started on the strength of a contusion with formation of a periproctal absceding haematoma. A patienthood led to the long-term intensive care with a necessity of multiple surgeries and with subsequent rehabilitative care. This case is rare by the origin of thus extensive infection of soft tissue and its illustration of the heftiness of the patient's treatment with such a disease. CONCLUSION: Fournièr's gangrene and necrotizing fasciitis are loaded by a high-grade of mortality. It is one of the most serious surgical infection, which ends by death frequently. The therapy is primarily surgical, but it cannot be sufficient without aggressive intensive care of a patient.

It is suggested that limited access to appropriate care forces psychiatric patients towards forensic treatment or to the prison system. According to our data, the number of prisoners, the number of hospitalized psychiatric patients (from 1987 to 2007), the number of court ordered forensic treatments in the Czech Republic (from 1991 to 2007), and the rate of people in psychiatric and sex offender forensic treatment has remained constant. However, an increase (162%) in number of treatments imposed for abusing illicit drugs did occur during this period. This increase contributed to the correlation between both the number of sentences given for protective treatment and the number of all sentenced persons (Pearson cor. 0.647, p < 0,001) and the number of prisoners (Pearson cor. 0.798, p < 0,001). The analysis of all admissions to a forensic facility from a catchment area of 1,260,318 inhabitants shows no increase in number of admission between 2002 and 2007. The same data prove that the number of patients ordered to psychiatric and sexology treatment remained steady and did not reflect changes in the number of prisoners or number of hospitalized patients. This could be explained by a high number of psychiatric hospitalizations protecting the patients from deteriorating to criminal behaviour.

UNLABELLED: Perfect maternal diabetes compensation is crucial for the outcome of the baby. However, little is known how hyperglycaemia influences the specific immune response. Furthermore, babies of type 1 diabetes (T1D) mothers have less risk of development T1D than babies with a T1D father. This study aimed to analyze the effect of maternal hyperglycaemia on newborns with focus on the response to diabetes-associated autoantigens. POPULATIONS: (1) Newborns of T1D mothers split into groups according to maternal diabetes compensation during the 3rd trimester: perfect (n = 15) or acceptable (n = 25) compensation. (2) newborns with T1D father (n = 12) (3) newborns with a mother treated for either gestational or type 2 diabetes (n = 10) (4) control newborns (n = 25). Spontaneous as well as diabetes-associated autoantigen-stimulated production of 23 cytokines and chemokines were tested using protein microarray. In addition, the influence of glucose on cytokine and chemokine responsiveness was analyzed in vitro. The study groups differed in their spontaneous as well as stimulated cytokine and chemokine spectra. A prominent Th1 response (high IFN-gamma) from autoantigen stimulation was observed especially in babies of T1D fathers (P = 0.001) and also in mothers with perfect diabetes compensation during the 3rd trimester (P = 0.016) in comparison with control newborns. By contrast, cord blood mononuclear cells cultivated in vitro in high glucose concentration decreased the diabetogenic stimulated Th1 cytokine response. Maternal 'sweet' as well as 'autoimmune environment' may both lead to lower occurrence of T1D within their offspring. Further studies will reveal the exact immunological mechanism of this observation.
