[Modern problems of modelling and treatment of soft tissues abscesses]. / Sovremennye problemy modelirovaniya i lecheniya abstsessov myagkikh tkanei.

Increase of the frequency of soft tissues pyoinflammatory diseases and purulent-septic complications against the background the antibiotic-resistance of organism dictates the necessity of search of rational new surgical technologies and preparations with the intense bactericidal effect. Period of the connective tissue (cicatrix) formation on a place of wound defect of the operated purulent abscess of soft tissue (PAST) is defined by the speed of the granulations and epithelial tissue formation. Therefore, one of the task of experimental surgery is search of new methods of the effective postoperative influence on terms of the regeneration and complete obliteration of the PAST cavity. The perspective direction in treatment of surgical infection is application of metals nanoparticles. In treatment of pyoinflammatory processes it is applied the preparation Eplan and also zinc oxide nanoparticles which have bactericidal, antiinflammatory and regenerative effects. However, till now it was not carried out experimental works on modelling and surgical treatment of PAST with local application of the laser technologies in combinations with Eplan and metals nanoparticles.

[Infected Thoracic Aortic Aneurysm Secondary to the Purulent Pericarditis;Report of a Case].

A 69-year-old man was hospitalized urgently to the department of cardiology, with the progressive general malaise. On admission, his blood pressure was 80/42 mmHg, his white cell count 13,700/µl, and C-reactive protein 25.55 mg/dl suggesting existence of aggressive infection with impaired circulation. Massive pericardial effusion was detected in echocardiography. Pericardial drainage was undergone promptly. There was drainage of 700 ml and the property was purulent. Pneumococcus was detected by the culture test of the pericardial fluid. Antibiotic administration was started by a diagnosis of the purulent pericarditis. His general condition was improved. However, a rapidly expanding saccular aneurysm was found in a descending thoracic aorta by computed tomography( CT). As an infected thoracic aortic aneurysm secondary to the purulent pericarditis, we performed thoracic endovascular aneurysm repair (TEVAR). The intravenous administration of antibiotics was continued for 2 weeks after TEVAR, which was followed by oral antibiotic administration for 1 year. The aneurysm completely disappeared by CT, 10 months after TEVAR. In case with an infected thoracic aortic aneurysm, TEVAR can be a 1st choice of treatment, depending on a causative organism and the morphology of the aneurysm.

Percutaneous suction and irrigation for the treatment of recalcitrant pyogenic spondylodiscitis.

BACKGROUND: The primary management of pyogenic spondylodiscitis is conservative. Once the causative organism has been identified, by blood culture or biopsy, administration of appropriate intravenous antibiotics is started. Occasionally patients do not respond to antibiotics and surgical irrigation and debridement is needed. The treatment of these cases is challenging and controversial. Furthermore, many affected patients have significant comorbidities often precluding more extensive surgical intervention. The aim of this study is to describe early results of a novel, minimally invasive percutaneous technique for disc irrigation and debridement in pyogenic spondylodiscitis. MATERIALS AND METHODS: A series of 10 consecutive patients diagnosed with pyogenic spondylodiscitis received percutaneous disc irrigation and debridement. The procedure was performed by inserting two Jamshidi needles percutaneously into the disc space. Indications for surgery were poor response to antibiotic therapy (8 patients) and the need for more extensive biopsy (2 patients). Pre- and postoperative white blood cell count (WBC), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), Oswestry disability index (ODI), and visual analogue score (VAS) for back pain were collected. Minimum follow-up was 18 months, with regular interval assessments. RESULTS: There were 7 males and 3 females with a mean age of 67 years. The mean WBC before surgery was 14.63 × 109/L (10.9-26.4) and dropped to 7.48 × 109/L (5.6-9.8) after surgery. The mean preoperative CRP was 188 mg/L (111-250) and decreased to 13.83 mg/L (5-21) after surgery. Similar improvements were seen with ESR. All patients reported significant improvements in ODI and VAS scores after surgery. The average hospital stay after surgery was 8.17 days. All patients had resolution of the infection, and there were no complications associated with the procedure. CONCLUSIONS: Our study confirms the feasibility and safety of our percutaneous technique for irrigation and debridement of pyogenic spondylodiscitis. Percutaneous irrigation and suction offers a truly minimally invasive option for managing recalcitrant spondylodiscitis or for diagnostic purposes. The approach used is very similar to discography and can be easily adapted to different hospital settings. LEVEL OF EVIDENCE: Level III.

[Surgical resolutions determining outcomes of infected pancreatic necrosis]. / Khirurgicheskie resheniia, opredeliaiushchie iskhod lecheniia infitsirovannogo pankreonekroza.

AIM: To evaluate technology, indications and time of minimally invasive semi-closed and laparotomic sanations for infected pancreatic necrosis (IP). MATERIAL AND METHODS: Initially it was used sonography-assisted minimally invasive semi-closed drainage of IP with gradual augmentation of catheters' diameter. In 462 patients with IP liquid pus prevailed over sequesters in epigastric localized pancreatonecrotic phlegmon (ELPF) and pancreatonecrotic abscesses. So, minimally invasive approach may be definitive. Epigastric advanced pancreatonecrotic phlegmon with predominant sequesters is often followed by conversion to transverse omentobursopancreatostomy (OBPS) to open all purulent accumulations. RESULTS: Surgical treatment immediately after parapancreatic infiltrate suppuration (i.e. within 3-4 weeks after onset of the disease) is associated with reduced mortality. Absent result of minimally invasive drainage is followed by mortality from the 11th day and maximum in 14 days after treatment onset. Therefore, focal IP resistant to minimally invasive drainage requires conversion to transverse OBPS or video-assisted sequestrectomy after 10-13 days. The lowest mortality (14.8±2.5%) was observed in patients who underwent minimally invasive drainage or transverse OBPS within 10-13 days. Ineffective prolonged minimally invasive drainage was accompanied by high mortality rate (60.7±3.2%, p<0.001). CONCLUSION: Conversion to transverse OBPS or video-assisted sequestrectomy are required if minimally invasive drainage of IP is ineffective after 10-13 days. Clear understanding of indications for closed and open drainage of PI helps to avoid tactical and technological errors.

[VACUUM-THERAPY OF DIFFUSE PERITONITIS].

The experience of treatment of 37 patients, suffering diffuse peritonitis, in 18 of them in complex with vacuum-therapy, is adduced. In a comparison group a sanation relaparotomy was applied only. International classifications SOFA, APACHE II, Manheim's Index of the Peritonitis Severity were used for estimation of the patients' state severity. The vacuum-therapy application have promoted significant reduction of the abdominal cavity microbial soiling, permitted to escape the compartment syndrome occurrence, and to reduce the sanation relaparotomy performance rate.

[APPLICATION OF VACUUM-THERAPY IN COMPLEX OF TREATMENT OF THE LOWER EXTREMITIES CHRONIC WOUNDS].

Experience of treatment of chronic wounds in 11 patients in 2014 ­ 2016 yrs was analyzed. The impact of negative pressure, using domestically manufactured apparatus «ÐGАТ- Dnepr¼, in complex of treatment as a local therapy, was applied. Vacuum-therapy was conducted preoperatively and postoperatively together with autodermoplasty. The injection material for the skin regeneration "lacerta" was applied subcutaneously intraoperatively. The Ialuset-cream bandages were used in 10 - 12 days postoperatively during 2-3 weeks. Еfficacy of vacuum-therapy was estimated, basing on analysis of the wound process course dynamics, clinic-laboratory criteria, terms of the wound defect complete closure. The patients' stationary treatment duration have constituted 38.3 days at average. Complex treatment of chronic wounds have had guaranteed complete healing of the wound defect in 7 (63%) patients in terms up to 1 - 5 weeks, and in 3 (26%) - 6 weeks.

[APPLICATION OF VACUUM-THERAPY ON STAGES OF SURGICAL TREATMENT OF THE DIABETIC FOOT SYNDROME].

Vacuum therapy of an acute and chronic wounds was used in a complex of surgical treatment of 228 patients, suffering diabetic foot syndrome. There was established a positive local and systemic action of this method for the treatment of the wound defect. Vacuum therapy of the wounds guarantees the wound process clinical course stabilization, improvement of microcirculation, reduction of their microbial soiling, stimulation of regenerative processes, elimination of endogenous intoxication.

Laparoscopic Lavage Is Feasible and Safe for the Treatment of Perforated Diverticulitis With Purulent Peritonitis: The First Results From the Randomized Controlled Trial DILALA.

OBJECTIVE: To evaluate short-term outcomes of a new treatment for perforated diverticulitis with purulent peritonitis in a randomized controlled trial. BACKGROUND: Perforated diverticulitis with purulent peritonitis (Hinchey III) has traditionally been treated with surgery including colon resection and stoma (Hartmann procedure) with considerable postoperative morbidity and mortality. Laparoscopic lavage has been suggested as a less invasive surgical treatment. METHODS: Laparoscopic lavage was compared with colon resection and stoma in a randomized controlled multicenter trial, DILALA (ISRCTN82208287). Initial diagnostic laparoscopy showing Hinchey III was followed by randomization. Clinical data was collected up to 12 weeks postoperatively. RESULTS: Eighty-three patients were randomized, out of whom 39 patients in laparoscopic lavage and 36 patients in the Hartmann procedure groups were available for analysis. Morbidity and mortality after laparoscopic lavage did not differ when compared with the Hartmann procedure. Laparoscopic lavage resulted in shorter operating time, shorter time in the recovery unit, and shorter hospital stay. CONCLUSIONS: In this trial, laparoscopic lavage as treatment for patients with perforated diverticulitis Hinchey III was feasible and safe in the short-term.

Two-year clinical outcomes following non-surgical mechanical therapy of peri-implantitis with adjunctive diode laser application.

BACKGROUND: Non-surgical mechanical therapy of peri-implantitis (PI) with/without adjunctive measures yields limited clinical improvements. AIM: To evaluate the clinical outcomes following non-surgical mechanical therapy of PI with adjunctive application of a diode laser after an observation period ≥2 years. MATERIAL AND METHODS: At baseline (BL), 15 patients with 23 implants with a sandblasted and acid-etched (SLA) surface diagnosed with PI were enrolled and treated. PI was defined as presence of probing pocket depths (PPD) ≥5 mm with bleeding on probing (BoP) and/or suppuration and ≥2 threads with bone loss after delivery of the restoration. Implant sites were treated with carbon fiber and metal curettes followed by repeated application of a diode laser 3x for 30 s (settings: 810 nm, 2.5 W, 50 Hz, 10 ms). This procedure was performed at Day 0 (i.e., baseline), 7 and 14. Adjunctive antiseptics or adjunctive systemic antibiotics were not prescribed. RESULTS: All implants were in function after 2 years. The deepest PPD decreased from 7.5 ± 2.6 mm to 3.6 ± 0.7 mm at buccal (P < 0.0001) and from 7.7 ± 2.1 mm to 3.8 ± 0.9 mm at oral sites (P < 0.0001), respectively. The % of implants with ≥1 site with BoP decreased from 100% at BL to 43% after 2 years (P = 0.0002). The % of implants with suppuration decreased from 87% at BL to 0% after 2 years (P < 0.0001). CONCLUSION: Non-surgical mechanical therapy of PI with adjunctive repeated application of a diode laser yielded significant clinical improvements after an observation period of at least 2 years.

[Pustular psoriasis]. / Pustulöse Psoriasis.

A number of pustular skin diseases share clinical, pathogenetic, and epidemiological aspects with plaque-type psoriasis, and their classification as a separate clinical entity or as a subtype of psoriasis remains controversial, which is also reflected in the multitude of their names. They include generalized pustular psoriasis with its subtypes, acrodermatitis continua suppurativa (Hallopeau), acute pustulosis palmopantaris, palmoplantar pustular psoriasis, and pustular variants of a mostly TNF-blocker triggered paradoxical psoriasiform dermatitis. In this article, the epidemiology, clinical picture, pathogenesis, genetics, and therapy of these pustular skin diseases are described.

EVALUATION OF THE USE OF OZONE THERAPY IN TREATMENT OF INFLAMMATORY PROCESSES IN DIABETES MELLITUS IN AN EXPERIMENT.

Studying the effect of ozone therapy on the course of pyoinflammatory processes with diabetes mellitus in the experiment, conducted on 30 white 24-30 month rats, weight 300-450 gr with purulent-inflammatory processes, it was found out that diabetes, which was simulated by subcutaneous injection of alloxan, causes mosaic disturbances of hemostasis system in the presence of pyoinflammatory processes. Complicated changes in blood condition were also detected against the background of diabetes mellitus: chronometric hypocoagulation on the intrinsic pathway of blood coagulation in association with chronometric hypercoagulation by the external thrombinogenesis mechanism and fibrinogenesis depression against the background of hypofibrinogenaemia. Thus, the use of ozone therapy in the presence of soft tissues abscesses in old rats with diabetes does not demonstrate significant protective properties with reduced azoalbumin lysis, total non-enzymatic fibrinolytic activity and proteinase activity by Kunitz in blood plasma. Such changes in old rats can be considered as an exacerbation of purulent inflammation, increase in toxicity, reduced protective properties, increase in manifestations of hypercoagulation against the background of chronic course of diabetes, caused by age-related changes.

[ROLE OF ULTRASONIC CAVITATION IN COMPLEX TREATMENT OF SUPPURATIVE-NECROTIC COMPLICATIONS OF DIABETIC FOOT SYNDROME].

The microbial landscape of wounds with suppurative-necrotic complications in diabetic foot syndrome (DFS) was investigated. Capabilities by inhibiting the formation of bacterial biofilms using ultrasonic cavitation (USC) were determined. In 32 patients over the purulent necrotic complications DFS USC applied using the apparatus "Sonoca-180" company Soring (Germany), 20 patients performed a basic therapy. Qualitative and quantitative composition of microflora were determined by the results of microbiological investigations using parallel transmission electron microscopy dynamics with USC. In patients with DFS noted the formation of bacterial biofilms that contained clusters of microorganisms in a polysaccharide matrix and were fixed to the wound surface. In the microbial landscape of wounds dominated gram-negative microorganisms. Application of USC contributed to the rapid cleanse wounds.

[The algorithm for the combined treatment of pyoinflammatory ENT diseases in the patients with diabetes mellitus].

The objective of the present study was to determine the leading clinical and pathogenetic factors determining the clinical course of the pyoinflammatory ENT diseases in the patients with diabetes mellitus (DM) and to develop the algorithm for the rational therapy of these conditions. A total of 145 patients presenting with pyoinflammatory ENT diseases and concomitant diabetes mellitus were available for the examination that included the microbiological and biochemical studies, determination of the total lipid spectrum, glycated hemoglobin (HbA1c) level, and glycemic profile. Also, the body mass index of the patients was estimated along with the type and severity of obesity. Moreover, the character of antibacterial and hypoglycemic therapy was evaluated. The mathematical analysis of the data obtained revealed the clinical and biochemical parameters determining the clinical picture of the pyoinflammatory ENT diseases in the patients with diabetes mellitus. These were localization of the pyogenic process in the larynx, abdominal obesity, fasting hyperglycemia in excess of 8.3 mmol/l, and dyslipidemia accompanied by the reduction in the amount of high density lipoproteins to below 40 mg/100 ml and the increase of low density lipoproteins to above 155 mg/100 ml. The results of the study were used to develop the differentialalgorithm for the combined treatment of pyoinflammatory ENT diseases in the patients with diabetes mellitus based on the proposed original scale for the prediction of pyogenic complications.

Indications and limitations of conservative treatment for pyogenic spondylitis.

STUDY DESIGN: Retrospective comparative study. OBJECTIVE: To elucidate the indications and limitations of conservative treatment for pyogenic spondylitis (PS). SUMMARY OF BACKGROUND DATA: The optimal strategy for treating PS, conservative or surgical, remains controversial. METHODS: Sixty-eight consecutive patients (44 males, 24 females; 62.6±13.8 y) suffering from PS were enrolled. Forty-three were successfully treated with conservative therapy including immobilization and administration of antibiotics [conservative treatment success (CTS) group]. Twenty-five patients underwent surgical intervention because of ineffective conservative treatment [conservative treatment failure (CTF) group]. Clinical parameters such as duration of symptoms, C-reactive protein (CRP) at admission, durations of hospital stay, and Frankel score, and radiologic parameters such as the presence of epidural abscess, were investigated in both groups. RESULTS: The duration of symptoms, CRP at admission, and the duration of hospital stay were 1.72±1.02 months, 5.89±6.29 mg/dL, and 85.7±46.0 days, respectively, in the CTS group compared with 7.92±16.9 months, 2.22±3.08 mg/dL, and 95.0±28.0 days in the CTF group. Differences were significant. At follow-up, 100% of the CTS group and 84% of the CTF group were ambulatory. A total of 86.1% of the CTS group lesions occurred at the lumbosacral region, whereas the majority (52%) of those in the CTF group were in the thoracic region. The incidence of epidural abscess was higher in the CTF group (84.0%) than in the CTS group (30.2%), and their greatest likelihoods were at the cervical/thoracic regions and lumbosacral region, respectively. CONCLUSIONS: The early phase of PS, in which the duration of disease between onset and admission was short and CRP at admission was active, was a good indication for conservative treatment regardless of the sites if there was neither paralysis nor worsening of kyphosis, and can even be an option for cases with mild paralysis due to epidural abscess occurring at the lumbosacral region.

[Use of high-frequency chest wall oscillation in an exacerbation of chronic pyo-obstructive bronchitis in adult patients with cystic fibrosis].

AIM: To evaluate the efficiency of high-frequency chest wall oscillation in the treatment of an exacerbation of chronic pyo- obstructive bronchitis in adult patients with cystic fibrosis (CF). SUBJECTS AND METHODS: A simple open-label comparative study enrolled 31 patients with CF. C-reactive protein (CRP), spirometric indicators (forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow), hemoglobin oxygen saturation, anthropometric data, six-minute walk test, and dyspnea rating by the MRC scale were assessed before treatment and on the last day of hospitalization. All the patients received conventional drug therapy; the study group patients (n=15) had the latter in combination with vibration-compression therapy for 15 minutes twice daily at a vibration frequency of 9-12 Hz and at an amplitude of 6-9 bars; the treatment cycle lasted 12-14 days. RESULTS: Both groups showed significant changes in spirometric and pulsometric readings, 6-minute walk test results, and MRC score. Body mass index increased and CRP decreased in the majority of patients in both groups. There were significant group differences in functional and anthropometric changes: 10.0 ± 4.6 and 6.9 ± 3.6% for FEV1 (p = 0.04) and 9.5 ± 4.8 and 5.9 ± 3.8% for FVC (p = 0.03) in the study and control groups, respectively. CONCLUSION: Incorporation of vibration-compression therapy (Vest vibro drainage) into the combination treatment of adult patients with CF results in significantly improved bronchial patency and more effective abolishment of an exacerbation.

The Immediate Clinical Effects Following a Single Radial Shock Wave Therapy in Pressure Ulcers: A Preliminary Randomized Controlled Trial of The SHOWN Project.

Objective: Recent preliminary reports indicate that extracorporeal shock wave therapy (ESWT) might be useful for chronic wounds, especially venous leg ulcers and diabetic foot ulcers. However, there is limited evidence for the utility and safety of ESWT in pressure ulcers (PUs). Therefore, this randomized controlled trial (RCT) aimed to assess immediate planimetric and clinical effects following a single radial ESWT session in PUs. Approach: A group of 40 patients with PUs was randomly assigned into 2 groups: active ESWT (n = 20), which underwent a single treatment with radial ESWT (300 + 100 impulses/1 cm2, 2.5 bars, 0.15 mJ/mm2, and 5 Hz) and placebo ESWT (n = 20), which was exposed to sham-radial ESWT. All patients continued standard wound care procedures. The planimetric assessment and clinical outcomes using Wound Bed Score (WBS) and Bates-Jansen Wound Assessment Tool (BWAT) were assessed before (M0) and after ESWT sessions (M1). Results: There was a significant planimetric enhancement observed after active ESWT reported as a reduction in all metric parameters: wound area from 11.51 to 8.09 cm2 (p < 0.001), wound length from 4.97 to 4.41 cm (p < 0.001), and wound width from 3.15 to 2.49 cm (p < 0.0001). Also, there was a significant beneficial clinical improvement observed with a WBS as an increased score from 3.85 to 9.65 points (p < 0.001) and with the BWAT as a decreased score from 45.45 to 30.70 points (p < 0.001). In turn, a regression in the placebo ESWT group was observed in all studied outcomes. Innovation: This study is the first RCT to provide the positive and immediate clinical effects of radial ESWT in promoting the healing of PUs. Conclusion: This preliminary RCT showed that even a single session of ESWT is a promising and clinically effective modality in managing PUs. However, there is still limited data regarding the usefulness of ESWT in PUs, and further studies are in demand.
