[Invasive ENT infections in immunocompetent schoolchildren in the winter half year 2022/23 : A case series]. / Invasive HNO-Infektionen bei immunkompetenten Schulkindern im Winterhalbjahr 2022/23 : Eine Fallserie.

We report a case series of severe complications following rhinosinusitis in the winter season 2022/2023 at the Franz-Lust Hospital for children and adolescents. Due to the severity of these complications in children with suspected complicated rhinosinusitis/orbital phlegmona, an immediate interdisciplinary approach is mandatory to prevent long-term sequelae. In addition, during this time period, we observed the unusual occurrrence of a number of invasive streptococcal infections in this age cohort.

Early Anti-Tumor-Necrosis-Factor Therapy for Crohn's Disease-Related Abdominal Abscesses and Phlegmon in Children.

BACKGROUND: Internally penetrating Crohn's Disease complications, including abscesses and phlegmon, represent a high-risk Crohn's Disease phenotype. Anti-tumor-necrosis-factor-α (Anti-TNF) therapies are effective in treating penetrating Crohn's Disease and early initiation has shown unique benefits. However, timing of anti-TNF initiation in the setting of internally penetrating Crohn's Disease complications is typically heterogenous due to concern over precipitating serious infections. Recent studies demonstrate such an association may not exist. AIMS: We aimed to describe the multidisciplinary management of pediatric patients with internally penetrating Crohn's Disease complications, focusing on the utilization and timing of anti-TNF therapy relative to complication resolution and adverse events. METHODS: We performed a single-center retrospective cohort study of pediatric patients with internally penetrating Crohn's Disease complications from 2007 to 2021. The safety and effectiveness of anti-TNF therapy initiation prior to complication resolution was assessed by comparing rates of infectious and Crohn's Disease-related adverse events between those who received anti-TNF therapy prior to complication resolution, versus those who did not. RESULTS: Twenty-one patients with internally penetrating Crohn's Disease complications were identified. 7/21 received anti-TNF therapy prior to complication resolution. Infectious adverse events within 90 days of complication occurred in 0/7 patients initiating anti-TNF therapy prior to complication resolution and 10/14 patients who did not (p = 0.004). Crohn's Disease-related surgeries and hospitalizations within 1 year of complication occurred in 12/20 patients, with similar frequency between groups. CONCLUSIONS: Initiating anti-TNF therapy prior to internally penetrating Crohn's Disease complication resolution may be a safe and effective strategy to improve clinical outcomes.

Incidence rate and histology of appendiceal neoplasms in complicated versus uncomplicated appendicitis: A meta-analysis and systematic review.

INTRODUCTION: Studies evaluating the rate and histology of appendiceal neoplasms between complicated and uncomplicated appendicitis include a small number of patients. Therefore, we sought a meta-analysis and systematic review comparing the rates and types of appendiceal neoplasm between complicated and uncomplicated appendicitis. METHODS: We included articles published from the time of inception of the datasets to September 30, 2022. The electronic databases included English publications in Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, and Scopus. RESULTS: A total of 4962 patients with appendicitis enrolled in 4 comparative studies were included. The mean age was 43.55 years (16- 94), and half were male (51%). Based on intra-operative findings, 1394 (38%) had complicated appendicitis, and 3558 (62%) had uncomplicated appendicitis. The overall incidence rate of neoplasm was 1.98%. No significant difference was found in the incidence rate of appendiceal neoplasm between complicated (3.29%) and uncomplicated (1.49%) appendicitis (OR 0.44, 95% CI 0.16- 1.23; p < 0.087; I2 = 54.9%). The most common appendiceal neoplasms were Neuroendocrine Tumors (NET) (49.21%), Nonmucinous Adenocarcinoma (24.24%), Mixed Adeno-Neuroendocrine Tumor (MANEC) (11.40%), Mucinous Adenocarcinoma (4.44%). There was a significant difference between complicated and uncomplicated appendicitis in rates of adenocarcinoma (50% vs. 13%), NET (31% vs. 74%), MANEC (19% vs. 13%) (P < 0.001). CONCLUSION: While there was no significant difference in the overall neoplasm rate between complicated and uncomplicated appendicitis, the NET rate was significantly higher in uncomplicated appendicitis. In comparison, the Adenocarcinoma rate was considerably higher in Complicated appendicitis. These findings emphasize the importance of evaluating risk factors for neoplasm when considering appendectomy in patients with appendicitis.

Lacticaseibacillus rhamnosus dfa1 Attenuate Cecal Ligation-Induced Systemic Inflammation through the Interference in Gut Dysbiosis, Leaky Gut, and Enterocytic Cell Energy.

Despite an uncommon condition, the clinical management of phlegmon appendicitis (retention of the intra-abdominal appendiceal abscess) is still controversial, and probiotics might be partly helpful. Then, the retained ligated cecal appendage (without gut obstruction) with or without oral Lacticaseibacillus rhamnosus dfa1 (started at 4 days prior to the surgery) was used as a representative model. At 5 days post-surgery, the cecal-ligated mice demonstrated weight loss, soft stool, gut barrier defect (leaky gut using FITC-dextran assay), fecal dysbiosis (increased Proteobacteria with reduced bacterial diversity), bacteremia, elevated serum cytokines, and spleen apoptosis without kidney and liver damage. Interestingly, the probiotics attenuated disease severity as indicated by stool consistency index, FITC-dextran assay, serum cytokines, spleen apoptosis, fecal microbiota analysis (reduced Proteobacteria), and mortality. Additionally, impacts of anti-inflammatory substances from culture media of the probiotics were demonstrated by attenuation of starvation injury in the Caco-2 enterocyte cell line as indicated by transepithelial electrical resistance (TEER), inflammatory markers (supernatant IL-8 with gene expression of TLR4 and NF-κB), cell energy status (extracellular flux analysis), and the reactive oxygen species (malondialdehyde). In conclusion, gut dysbiosis and leaky-gut-induced systemic inflammation might be helpful clinical parameters for patients with phlegmon appendicitis. Additionally, the leaky gut might be attenuated by some beneficial molecules from probiotics.

A new approach to the management of acute appendicitis: Decision tree method.

BACKGROUND: It is important to distinguish between complicated acute appendicitis (CAA) and noncomplicated acute appendicitis (NCAA) because the treatment methods are different. We aimed to create an algorithm that determines the severity of acute appendicitis (AA) without the need for imaging methods, using the decision tree method. METHODS: The patients were analyzed retrospectively and divided into two groups as CAA and NCAA. Age, gender, Alvarado scores, white blood cell values (WBC), neutrophil/lymphocyte ratios (NLR), C-reactive protein value (CRP), albumin value and CRP/Albumin ratios of the patients were recorded. RESULTS: In the algorithm we created, the most important parameter in the distinction between CAA and NCAA is CRP. NLR is predictive in patients with a CRP value of ≤107.565 mg/L, and the critical value is NLR 2.165. In patients with a CRP value of >107.565 mg/L, albumin is the determinant and the critical value is 2.85 g/dL. Age, gender, alvarado score and CRP/albumin ratio have no significance in distinguishing between CAA and NCAA. In the statistical analysis, there were significant differences between NCAA and CAA groups in terms of age (39.56 years vs 13,675 years), gender (48.1% male vs 71.4% male), WBC (13,891.10/mL vs 11,614.76/mL), CRP (27 mg/L vs 127 mg/L), albumin (3 g/dL vs 3 g/dL) and CRP/albumin (9.50 vs. 41). CONCLUSION: Thanks to the algorithm we created, CAA and NCAA distinction can be made quickly. In addition, by avoiding unnecessary surgical procedures in NCAA cases, patients' quality of life can be increased and morbidity rates can be minimized.

[Infections of the hand and forearm]. / Infektionen der Hand und des Unterarms.

Infections of the hand and forearm are a frequently seen surgical emergency of the hand. Patients of all age groups are affected and underlying systemic diseases are risk factors. Posttraumatic causes are the leading cause of infections. This includes cuts and stab wounds, animal and human bites but often also minor injuries. Due to the anatomical peculiarities of the hand, rapid progression of initially inconspicuous infections can occur resulting in functional limitations. If an infection is suspected, a symptom-oriented evaluation by a hand surgeon should be performed. This includes a detailed patient history, clinical examination, laboratory analyses and imaging. This is followed by the development of an individualized and interdisciplinary treatment concept with the aim of achieving the shortest possible rehabilitation period. The treatment includes surgical cleansing of the infection, accompanied by antibiotic treatment taking the expected possible spectrum of pathogens into account. Cephalosporins and aminopenicillins in combination with beta-lactamase inhibitors are the antibiotics of first choice. Follow-up treatment includes early functional exercise under the guidance of a hand therapist to minimize postinfectious restrictions in the range of motion and to enable occupational rehabilitation. In rare cases, fulminant necrotizing infections with resulting skin and soft tissue defects can occur. In these cases, secondary plastic reconstruction is usually required after cleansing of the infection.

[Acute gangrenous-perforative appendicitis in right-sided inguinal hernia]. / Ostryi gangrenozno-perforativnyi appenditsit v pravostoronnei pakhovoi gryzhe.

The author presents acute appendicitis with atypical localization of appendix in hernial sac in a patient with right-sided inguinal hernia. Long-standing disease (3 days), progressive destructive process in appendix (gangrenous-perforative appendicitis) led to spread of infection beyond the hernial sac and development of local inflammatory process in inguinal tissues. Surgical team recognized this pattern as a complication of strangulated right-sided inguinal hernia (hernia sac phlegmon). Despite the diagnostic error, timely surgical intervention and adequate tactical approach contributed to a favorable outcome.

[Results of modified submandibular surgical approach usage for the mouth floor phlegmons treatment with respect to dynamic of local non-specific resistance]. / Rezul'taty primeneniya modifitsirovannogo podnizhnechelyustnogo operativnogo dostupa dlya lecheniya odontogennykh flegmon dna polosti rta s uchetom dinamiki lokal'noi nespetsificheskoi rezistentnosti.

THE AIM OF THE STUDY: Was increasing of treatment effectiveness of patients with mouth floor odontogenic phlegmon (MFOP) by modified of surgical approach usage. MATERIALS AND METHODS: The prospective controlled, randomized, simple blinded clinical trial, II b level of evidence, comprised 86 patients with MFOP which formed main and control groups. The main group consisted of 40 patients treated with designed «Method for surgical treatment of odontogenic oral phlegmon of mouth floor with partial dissection of sublingual-submandibular sac¼. The control group involved 46 patients treated with traditional surgical procedure. The differences significance between the values has been evaluated with nonparametric Fisher's exact P-test and parametric Student's t-test for independent samples. RESULTS: The modified surgical approach statistically significantly (p<0.05) decreased the number of inflammatory complications (from 26±7% to 9±4%), terms of secondary sutures application (from 7.9±1.4 to 5.7±1.6 days) and time of hospital stay (from 9.4±1.8 to 8.3±1.7 days). On the 5th day of treatment white blood cells count in the main group was significantly (p<0.05) lower (7.2±1.1·109/l) than in controls (9.4±1.3·109/l) showing improved intoxication syndrome resolution in the main group. Index of reaction of bacteria adsorption to the oral epithelium in the main group on the 5th day of treatment was significantly (p<0.05) higher (77.1±6.9%) than in controls (62.4±7.1%). More successful correction of local non-specific resistance was registered in the main group. CONCLUSION: The proposed modified submandibular surgical approach is more effective for the treatment of patients with MFOP.

Is interval appendectomy really needed? A closer look at neoplasm rates in adult patients undergoing interval appendectomy after complicated appendicitis.

BACKGROUND: The treatment algorithm for appendicitis is evolving, with recent interest in non-operative management. However, the safety of non-operative management for patients with complicated appendicitis has been questioned due to concern for increased risk of occult appendiceal neoplasm in this patient population. Our study aims to determine the rate of neoplasms discovered during interval appendectomy for patients with complicated appendicitis and determine the necessity of interval appendectomy. METHODS: A retrospective chart review was conducted on interval appendectomies performed in adult patients for complicated appendicitis at our institution over a 9-year period. Interval appendectomy was defined as appendectomy delayed from initial presentation with appendicitis. Complicated appendicitis was defined as perforation, phlegmon, and/or abscess as seen on computed tomography at time of presentation. RESULTS: We identified 402 patients who underwent interval appendectomy for complicated appendicitis. A total of 36 appendiceal neoplasms were discovered on final pathology with an overall neoplasm rate of 9%. Patients with an appendiceal neoplasm were significantly older (56.6 years vs 45.1 years, p < 0.01). No patients under the age of 30 had a neoplasm. The rate of appendiceal neoplasms in patients 30 years and older was 11%. The rate for patients 50 years and older was 16%. For patients 80 years and older, the rate of appendiceal neoplasm was 43%. CONCLUSION: The risk of occult appendiceal neoplasm is low in patients under the age of 30; however, there was an 11% rate of appendiceal neoplasm in patients 30 years and older. The risk increases with increased age, with a 16% risk in patients 50 years and older. Given these findings, we recommend consideration of interval appendectomy in all patients 30 years and older with complicated appendicitis.

Early versus delayed (interval) appendicectomy for the management of appendicular abscess and phlegmon: a systematic review and meta-analysis.

OBJECTIVE: The safety and role of emergency (EA) versus interval appendicectomy (IA) for appendicular abscess and phlegmon remains debatable with no optimal strategy identified. The aim of this systematic review and meta-analysis is to evaluate outcomes of managing appendicular abscesses and phlegmon with emergency or interval appendicectomy. METHODS: We conducted a systematic search of electronic databases using key terms including 'appendicular abscess', 'appendicular phlegmon' and 'interval appendicectomy'. Randomised controlled trials and observational studies comparing the two management approaches were included. Operative time, post-operation complication, unplanned bowel resection, rate of surgical site infection, post-operative length of stay and overall mortality rate were evaluated. RESULTS: We identified six studies (2 RCTs and 4 observational studies) with a total of 9264 patients of whom (n = 1352) underwent IA, and (n 7912) underwent EA. The EA group was associated with statistically significant unplanned bowel resection (OR 0.55, 95% CI [0.33-0.90], P = 0.02) and longer total operating time (MD - 14.11, 95% CI [- 18.26-- 9.96] P = 0.00001). However, the following parameters were compared for both EA and IA groups; there were no significant statistical differences: surgical site infection (OR 0.49, 95% CI [0.17-1.38], P = 0.18), post-operative intra-abdominal collection (RD - 0.01, 95% CI [- 0.04-0.01], P = 0.29), total length of hospital stay (MD 1.83, 95% CI [- 0.19-3.85], P = 0.08), post-operative length of hospital stay (MD - 0.27, 95% CI [- 3.66-3.13], P = 0.88) and mortality rate (MD - 0.27, 95% CI [- 3.66-3.13], P = 0.66). CONCLUSION: Emergency operation for appendicular abscess and phlegmon may lead to a higher rate of reported morbidity when compared with interval appendicectomy. Although emergency appendicectomy performed for appendicular abscess and phlegmon is a feasible and safe operative approach, it is associated with significantly increased operative time and unplanned bowel resection (ileocolic and right hemicolectomies) compared to interval appendicectomy.

[Sepsis after cat bite-How medical history, physical examination and interdisciplinary cooperation influence disease progression]. / Sepsis nach Katzenbiss ­ Wie Anamnese, körperliche Untersuchung und eine interdisziplinäre Zusammenarbeit den Krankheitsverlauf beeinflussen.

A 67-year-old woman with symptoms of shock was admitted to hospital with a suspected diagnosis of acute pulmonary artery embolism. After ruling out a thromboembolic event, sepsis was diagnosed by using the SOFA score. A CT scan of the chest with contrast revealed phlegmonous inflammation of the subcutis at the level of the right upper arm. After taking two pairs of peripheral blood samples, calculated antibiotic therapy with piperacillin/tazobactam was administered. After administration of an initial volume bolus, the patient could be transferred to the general medical ward in a stable condition with normal serum lactate level. On day one after hospital admission, blood cultures were positive for Pasteurella multocida, a gramnegative rod that belongs to the oral flora of dogs and cats. Intensified history revealed that the patient had been bitten on the forearm by her cat 2 weeks earlier. The patient did not present to a general practitioner. Despite antibiotic therapy, the patient developed increasing leukocytosis with progressive pain and swelling in the area of the right upper arm and the right ankle. On recommendation of the department of infectious diseases antibiotic therapy was escalated to imipenem and transesophageal echocardiography was performed. Endocarditic vegetations could be ruled out. Despite further escalation of the antibiotic regimen, spontaneous pus discharge occurred at the right ankle. A CT scan of the chest as well as the foot and the right ankle with contrast showed new abscess formations in the right thoracic wall between the pectoralis major and minor muscles as well as extensive abscesses in the extensor compartment of the right lower leg. On day 12 after admission, surgical drainage of multiple abscesses was performed, with rapid improvement in general condition and normalized leukocytes. A further six operations were necessary before the patient could be discharged home after 7 weeks of inpatient treatment.

[Purulent iliopsoitis: etiology, pathogenesis, diagnosis and surgical treatment]. / Gnoinyi iliopsoit: etiopatogenez, diagnostika, khirurgicheskoe lechenie.

Purulent iliopsoitis is a quite rare and difficult disease regarding diagnosis and treatment. However, treatment outcomes are not so favorable, incidence of sepsis and mortality are still extremely high. Original up-to-date studies devoted to this issue were analyzed. The authors discuss the actual problems of etiology, pathogenesis, classification, clinical features, diagnosis and surgical treatment of iliopsoitis. Considering these data, they conclude that timely diagnosis and adequate surgical treatment are essential for favorable outcomes. Prevention of relapse is based on detection of possible cause of disease and its possible correction.

Lactational phlegmon: A distinct clinical entity affecting breastfeeding women within the mastitis-abscess spectrum.

We aimed to describe the presentation and treatment of lactational phlegmon, a unique complication of mastitis in breastfeeding women that may require surgical management. We retrospectively analyzed medical charts of breastfeeding women treated by a single breast surgeon for lactational phlegmon or the related conditions of abscess or uncomplicated mastitis (UM) from July 2016 to October 2018. Demographic variables and treatment details were analyzed using ANOVA and Pearson's Chi-square test. Ten women with lactational phlegmon (19.2%), 15 women with abscess (28.8%), and 27 women with UM (51.9%) were identified. Phlegmon presented as a tender, erythematous, and nonfluctuant mass in a ductal distribution. Ultrasonography demonstrated an ill-defined, complex fluid collection. Epidemiologically, women with phlegmon were similar to patients with abscess and UM. Women with phlegmon reported more intense deep breast massage than patients in the other two groups, but significantly lower rates of breast pump use than women with abscess (30.0% vs 80.0%, P < .05). Relative to women with UM, patients with complicated mastitis (CM, defined as phlegmon or abscess) reported greater utilization of nipple shields (36.0% vs 11.1%, P < .05). Treatment of phlegmon entailed effective milk removal, antibiotics (range 10-30 days), and close follow-up until both clinical and radiographic resolution (range 8 days to >3 months), with biopsy of persistent masses. Antibiotic duration was significantly longer for patients with phlegmon compared to those with UM (mean 15.0 days vs 9.7 days, P < .05). Two phlegmons coalesced into abscesses within 1 week of diagnosis. Lactational phlegmon is a complication of mastitis in breastfeeding women that is distinct from abscess and UM. Optimal treatment consists of an extended course of antibiotics and close follow-up to monitor for coalescence into a drainable fluid collection and/or persistence of mass requiring biopsy.

National and foreign literature devoted to acute non-cryptogenic suppurations of pararectal tissue was analyzed. Own clinical observations are given. The unsolved questions of terminology and treatment strategy for this rare disease are discussed.

Bacterial species associated with interdigital phlegmon outbreaks in Finnish dairy herds.

BACKGROUND: Severe outbreaks of bovine interdigital phlegmon (IP) have occurred recently in several free stall dairy herds in Finland. We studied the aetiology of IP in such herds, and the association of bacterial species with the various stages of IP and herds of various morbidity of IP. Nineteen free stall dairy herds with IP outbreaks and three control herds were visited and bacteriological samples collected from cows suffering from IP (n = 106), other hoof diseases (n = 58), and control cows (n = 64). The herds were divided into high morbidity (morbidity ≥50%) and moderate morbidity groups (9-33%) based on morbidity during the first two months of the outbreak. RESULTS: F. necrophorum subspecies necrophorum was clearly associated with IP in general, and T. pyogenes was associated with the healing stage of IP. Six other major hoof pathogens were detected; Dichelobacter nodosus, Porphyromonas levii, Prevotella melaninogenica, Treponema spp. and Trueperella pyogenes. Most of the samples of acute IP (66.7%) harboured both F. necrophorum and D. nodosus. We found differences between moderate morbidity and high morbidity herds. D. nodosus was more common in IP lesion in high than in moderate morbidity herds. CONCLUSIONS: Our result confirms that F. necrophorum subspecies necrophorum is the main pathogen in IP, but also T. pyogenes is associated with the healing stage of IP. Our results suggest that D. nodosus may play a role in the severity of the outbreak of IP, but further research is needed to establish other bacteriological factors behind these severe outbreaks.

Pediatric cervical epidural abscess in a 4-year-old patient: a case-based update.

PURPOSE: The purpose of this study was to review a case comprised of a cervical spinal epidural abscess, cervical and thoracic paraspinous edema, and widening of the right thoracic neural foramen secondary to a phlegmon. METHODS: We reviewed the case of a spinal epidural abscess managed medically in a 4-year-old male and performed a review of the literature with 15 other cases that have previously been reported. RESULTS: The current mainstay of treatment is largely variant but generally falls into a laminectomy-based surgical approach or longstanding antibiotics. Our review of the literature concluded that there are currently no clear guidelines established to recommend treatment, and current practice is largely based on the discretion of the pediatric neurosurgeon. CONCLUSIONS: Based on the literature review, and our personal case illustration, we conclude that an antibiotic-based treatment is a valid approach for therapy if initiated promptly in a pediatric patient with no neurological deficit.

Surgical treatment of phlegmons of the digital flexor tendon sheaths at the early stage: Lavage by conventional open technique versus ultrasound-guided percutaneous technique.

The aim of this work was to analyze the results of a percutaneous drainage technique with 2 catheters during surgical treatment of phlegmons of the finger flexor tendon sheath. Our series included 32 patients with a phlegmon of flexor tendon sheaths, including 19 men and 13 women, mean age 43.4years. The first 16 patients (group I) were treated by a conventional open technique for the lavage and drainage of the affected tendon sheath. The last 16 (group II) were treated by an ultrasound-guided percutaneous lavage technique with 2 catheters: one proximal and one distal. In the case of impermeability of the digital canal, conversion by open technique was carried out. In group II, the ultrasound-guided percutaneous lavage was 5 times successful. Failure of the proximal catheter alone was noted once, whereas failure of the distal catheter alone was noted 7 times. The failure of both catheters was noted 3 times. At a mean follow-up of 19.7 days, mean handgrip strength was 56.5% compared to the contralateral side in group I and 82% in group II (P<0.05). However, there was no significant difference for pain, QuickDASH, total active mobility between group I and group II. Pain was at 1.4/10 for group I and 1.4/10 for group II. QuickDASH was measured at 27/100 for group I and 22.27/100 for group II. Total active mobility was 227° for group I and 243° for group II. In conclusion, surgical treatment of the phlegmons of the finger flexor tendon sheath with an ultrasound-guided percutaneous lavage technique gives significantly better short-term grip strength than the conventional open technique.

[Extensive purulent processes after combined phlebectomy]. / Obshirnye nagnoitel'nye protsessy posle kombinirovannoi flebéktomii.

OBJECTIVE: To analyze the causes and develop methods for the treatment of extensive purulent processes after combined phlebectomy in patients with lower limb varicose veins. MATERIAL AND METHODS: The authors reported 3 cases of extensive phlegmon after phlebectomy for the period from 2014 to 2018. It is shown that comprehensive debridement of purulent-inflammatory lesion with application of additional methods including high-energy exposure by the air-plasma flow is essential for effective treatment of this complication. In addition, literature review showed only few observations of severe septic complications after traditional varicose vein surgery. RESULTS: Radical debridement of purulent wounds with wide excision of necrotic subcutaneous tissue and fascia, combination of standard surgical technique and plasma scalpel, as well as subsequent plasmodynamic staged wound repair in a therapeutic mode prevented severe purulent-inflammatory process, stopped systemic inflammatory syndrome and resulted fast wound healing. CONCLUSION: Active surgical approach combined with air-plasma technology was followed by high-quality correction of extensive suppurative process. Minimally invasive management of varicose disease with improvement of surgical techniques will minimize the likelihood of these complications.

Outcomes of interval appendectomy in comparison with appendectomy for acute appendicitis.

BACKGROUND: Traditionally, patients treated conservatively for periappendiceal abscess or phlegmon would subsequently undergo interval appendectomy (IA); however, recent evidence has shed doubt on the necessity of this procedure. This study aimed to assess the outcomes of patients who underwent IA, in comparison with those operated acutely for appendicitis. MATERIALS AND METHODS: A retrospective analysis identified patients who underwent IA between 2000 and 2016. Their course and outcomes were compared with those of our previously published cohort of patients who underwent appendectomy for acute appendicitis. RESULTS: During the study period, 106 patients underwent IA. Their mean age was 39.7 ± 16.2 y, and 60.4% were females. In their index admission, 75.5% presented with abscesses. IA was performed successfully in all patients, and no patient required colectomy. Pathology demonstrated neoplastic lesions in 6/106, but only one was malignant. IA patients were compared with a cohort of 1649 acute appendectomy patients. This group was significantly younger (33.7 ± 13.3 y). Operation time was comparable between the groups (46.0 ± 26.2 versus 42.7 ± 20.9 min, respectively, P = 0.33). In the IA group, significantly more laparoscopic operations were performed (100% versus 93.9%), but with a higher conversion rate to open (1.9% versus 0.13%, P < 0.001). Although the overall complication rate was comparable, more intraoperative complications (2.8% versus 0.3%, P < 0.001) and deep/organ-space surgical site infections (surgical site infection; 4.7% versus 1.2%, P = 0.003) were reported in the IA group. CONCLUSIONS: IA can be a challenging procedure and should not be performed on a routine basis. However, neoplasia must be actively ruled out, particularly in the older age group.

[The experimental clinical substantiation of treatment of patients with odontogenic phlegmon of maxillofacial area using Dаlargin in complex therapy.]

The patients with odontogenic phlegmon of maxillofacial area suffer from immune depression at the surgical stage of treatment that can unfavorably affect their rehabilitation. The study analyzes possibility of application of medication Dalargin in complex treatment of patients during post-operation period. The experimental study established components of immune system affected by medication. Thereupon, Dalargin was applied in clinical practice of treatment of patients with course of disease of average severity. The study proved immunomodulatory characteristics of Dalargin effecting various fractions of sub-populations of lymphocytes and manifesting by way of decreasing of initially high indices and increasing of initially low indices that is of great importance during treatment of patients with odontogenic hormones, especially in case of severe course of disease.
