RESUMEN
BACKGROUND: The medicinal leech therapy (MLT) is a kind of complementary treatment method used for various diseases. The leeches (Hirudo medicinalis) have been used for more than 2500 years by surgeons. The substances presenting in the saliva of leeches have anti-inflammatory, anticoagulant, platelet inhibitory, thrombin regulatory, analgesic, extracellular matrix degradative and antimicrobial effects. The method is cheap, easy to apply, effective and its mechanisms of action have been clarified for specific diseases. Infection particularly Aeromonas infection is the most common complication of MLT. CASE PRESENTATION: In this case report, a keratitis case developing after leech therapy applied for the periocular and facial eczematous dermatitis lesions will be presented. The patient referred to our hospital with decreased vision, ocular pain, stinging, redness and lacrimation complaints. A large corneal epithelial defect with irregular margins, dying by fluorescein, involving more than inferior half of cornea and conjunctival hyperemia were seen in the right eye. No agent was determined in microbiological investigation, as the patient had used topical moxifloxacin eye drop which was commenced in another clinic before applying to us. The patient was treated with fortified vancomycin and ceftazidime, before using besifloxacin with the diagnosis of bacterial keratitis. Three weeks later epithelial defect improved completely leaving an opacity and neovascularization. CONCLUSIONS: MLT should be performed by certified physicians with sterile medicinal leeches and precautious antibiotics should be used before MLT for prevention against potential infections.

OBJECTIVE: Medicinal leech therapy - known as hirudotherapy (HT) - is an empirical medical technique that has become popular again in reconstructive surgery. However, at each step of leech management there are risks for blood contamination of the caregivers and severe infections for patients. This reduces the success of the treatment. The aim of this study was to improve the management of leeches from ordering to disposal to improve patient care. METHODS: First, a review of the literature was performed. Second, we conducted a retrospective study of patients' antibiotic prophylaxis from January 2018 to December 2019. The data we collected were patient characteristics, the specific care unit at the hospital, indication, contra-indication, posology, duration of HT, number of leeches delivered, antibiotic prophylaxis prescribed and microbial organism, if identified. Third, an interdisciplinary meeting was organised to review the entire leech circuit: ordering, maintenance, prescription, dispensing, application and disposal. RESULTS: At the end of the literature review, six articles based on practices implemented in France were selected for inclusion. These articles discussed antibiotic prophylaxis, iron supplementation, and leech storage, application and disposal. On the retrospective study performed, antibiotic prophylaxis for HT was performed for 60% (30/50) of patients, 77% (23/30) of the prescriptions followed the recommendations for antibiotic prophylaxis, and 20 patients did not receive antibiotic prophylaxis. The interdisciplinary meeting made it possible to define a collegially validated protocol, containing a computerised antibiotic prophylaxis prescription, including per os ciprofloxacin antibiotic prophylaxis, intravenous iron supplementation and biological monitoring. A leech application protocol was created, and the method of leech disposal was revised. CONCLUSION: Despite the absence of clear guidelines and heterogeneous practices, this study reveals the importance of a standard procedure including leech management practices before use, antibiotic prophylaxis and application and disposal guides. The interdisciplinary protocol allows improved patient care management and makes leech management safer for caregivers.

The objective of this study was to report the clinical indications, outcomes, and complications associated with medicinal leech therapy (MLT) in dogs and cats. Medical records (2012-2016) of client-owned dogs (n = 9) and cats (n = 3) treated with MLT at one institution were retrospectively reviewed. Retrieved data included the signalment, indications, physical examination findings, laboratory results, methods of leeching, outcomes, and complications associated with MLT. Following MLT sessions, nine patients (75%) visibly showed clear improvement of the affected tissue. One patient (8%) was euthanized before complete healing owing to pulmonary parenchymal disease. Improvement or appearance of tissue following MLT was not recorded in two patients (17%). Results suggest that MLT may be a safe and effective treatment modality for venous congestion and necrosis in compromised skin flaps and wounds with success in resolving 75% of the lesions in this study. This study is suggestive of the value of MLT when more conventional treatment methods fail in dogs and cats. A data collection form was created for veterinarians to use with the goal of obtaining standardized, objective MLT data for future studies.

Intraoral hirudotherapy is traditionally used for venous congestion following head and neck free flap reconstruction. Many institutions and healthcare teams have been reluctant to use intraoral leech therapy due to risks such as migration into the airway, increased infection from intraoral manipulation, and patient discomfort. Several protocols recommend blocking the path to the oropharynx via gauze or leaving a tracheotomy in place to protect the airway. This report pre-sents a novel technique for intraoral hirudotherapy that is safe and simple for treatment of free flap venous congestion. The base of a clear cup or a plastic lid is utilized, and the leech is attached onto the inside of the lid with 2 sutures near each end. Several cups with leeches attached are made at a time to reduce delay and difficulty of application by less experienced clinical staff. The leech is then applied onto the compromised flap and then simply removed once it has unlatched from the flap. This method allows the leech to be applied with ease by multiple members of the healthcare team, decreases the need for intraoral manipulation, and reduces the risk of migration into the aerodigestive tract. Future prospective studies are warranted to assess the efficacy of this technique.

BACKGROUND: Total ear amputation is a relatively rare trauma with an absolute indication for surgical treatment. Numerous techniques for auricular reconstruction have been described. When local and general conditions allow microsurgical replantation, this must be the first choice. We propose the association of microsurgical techniques with some modification (modified Baudet technique) to obtain higher survival rate of the reimplanted stump. METHODS: This study included cases of 3 male patients with total ear amputation, the injuries and their mechanism (workplace accident) being identical. Chief complaints were pain, bleeding, important emotional impact due by an unaesthetic appearance. The established diagnosis was traumatic complete ear amputation (grade IV auricular injury according to Weerda classification). Microsurgical replantation was performed only with arteriorraphy, and no vein anastomosis. Cartilage incisions and skin excisions were made to enlarge the cartilage-recipient site contact area. Medicinal leeches were used to treat venous congestion, to which systemic anticoagulant therapy was added. RESULTS: The results showed the survival of the entire replanted segment in all cases, with good function and esthetical appearance. Patients were fully satisfied with the final outcome. CONCLUSION: Microsurgical replantation is the gold standard, for the surgical treatment of total ear amputation. We believe that cartilage incisions and the increased surface of contact between cartilage and recipient site has an adjuvant role in revascularization of the amputated stump (with only arterial anastomosis) and the use of hirudotherapy helps to relieve early venous congestion.

INTRODUCTION: Proliferative vitreous retinopathy (PVR) is characterized by proliferation of cells and contraction of membranes on either the retinal surface or in the vitreous cavity, which leads to retinal detachment and visual impairment. PVR is commonly seen in patients with rhegmatogenous retinal detachment and diabetic retinopathy, which seriously affects the patient's work and life. Previous studies indicated that Hirudo (Leech) or compound prescription containing Hirudo (Leech) for treatment of PVR would be effective. However, due to the lack of evidence, there are no specific methods or suggestions, so it is necessary to carry out systematic evaluations on Hirudo (Leech) for PVR and provide effective evidence for further research. METHODS AND ANALYSIS: The following 8 databases will be searched: Cochrane Central Register of Controlled Trials, PubMed, MEDLINE, EMBASE, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, VIP Database, and Wanfang Database. All randomized controlled trials in English or Chinese related to Hirudo (Leech) for PVR will be included. Outcomes will include change in Vitreous opacity, Vision changes, production of the anterior macular membrane, and retinal detachment again. The incidence of adverse events will be assessed for safety evaluation. Study inclusion, data extraction and quality assessment will be performed independently by 2 reviewers. Assessment of risk of bias and data synthesis will be performed using Review Manager V.5.3. RESULTS: In this systematic review and meta-analysis, we will synthesize the studies to assess the safety and efficacy of Hirudo (Leech) for PVR. CONCLUSION: The summary of our study will clarify whether Hirudo (Leech) therapy could be an efficient and safe method for PVR, which can further guide the promotion and application of it.

Background: Infections with Aeromonas spp. are a recognized complication of leech therapy for circulatory complications in replanted digits. Ciprofloxacin is commonly used empirically for Aeromonas coverage in such cases. Evolving resistance patterns of Aeromonas should be considered in designing an antibiotic strategy. Methods: Three consecutive patients with complicated replantations had site cultures yielding Aeromonas isolates resistant to ciprofloxacin. These cultures were analyzed to identify effective antibiotic agents. Results: Each Aeromonas isolate, and each additional site organism, was sensitive to cefepime. Conclusion: Our routine antibiotic coverage for leech application has been changed to cefepime. Aeromonas sensitivities and resistances should be monitored to adapt to future changes in appropriate antibiotics.

OBJECTIVE: to study the hirudotherapy efficacy in presbyacuzis praecox in clean-up workers (CUWs) of the Chornobyl disaster (ChD) during the post-accident years. MATERIALS AND METHODS: From archive data of previously examined 8,136 males' CUWs we selected among them 129 persons with the determined presbyacuzis praecox during the post-accident years. According to the physical dosime- try data the individual radiation of received by CUWs during the work on a rotational scheme in the Chornobyl exclu- sion zone from the end of 1986 to 1992-1994 amounted to 0.21-0.50 Gy. The examinations were carried out using a modern standard set of audiometric, vestibulometric and electrophysiological methods. Two forms of sensory and neural hearing loss in the elderly were distinguished, namely the presbyacuzis and presbyacuzis praecox. Prior to work in the exclusion zone, patients' auditory and vestibular functions were within normal range. Among 129 patients, 68 ones with presbyacuzis praecox were included in two main age groups (aged 40-49 and 50-59 yrs) and were treated using hirudotherapy, taking into consideration their coagulation hemostasis. Other 61 patients of analogical age groups were treated by allopathotherapy. For the analysis of results obtained, techniques of variational statistics were used. RESULTS: Direct correlation (r = 0.71) between inhibitory processes in central areas of the auditory analyzer in pres- byacuzis praecox in CUWs was established by electrophysiology and by speech audiometry data obtained before the treatment. Hyperacusis signs were detected in CUWs of two main and two control groups. Following the use of two treatment schemas, a significant improving of auditory functions was found (p < 0.05) according to tone and speech audiometries. The positive hirudotherapy effect concerning hearing functions was registered in 88% cases (in 59 CUWs among 68 ones); if allopathotherapy had been used, such effect was found in 65% cases (in 45 control patients among 61 ones of control group). The duration of allopathotherapy effect reached 6-9 months comparing to 12-18 months of hiruditherapy one, being twice longer. Improving the patients' coagulation hemostasis, hirudotherapy activated cardiovascular activity favoring the increase of social adequacy in CUWs with presbyacuzis praecox. CONCLUSIONS: It has been shown that hirudotherapy as a kind of naturopathy has significant advantages over alopa- totherapy by the absence of side effects, 23.0% higher and twice as long as improvement of auditory functions. Hirudotherapy, as an effective therapeutic and recreational measures, should be more widely implemented in clini- cal practice in order to minimize the development and progression of diseases in the special population of people who have been exposed to ionizing radiation due to the Chornobyl catastrophe to continue their vitality.

We report about hirudotherapy in a patient with chronic complex regional pain syndrome (CRPS) in the right hand. CRPS is a multifactorial disease associated with disabling pain as well as sensory and motor deficits. The optimal therapeutic management is based on personalized multimodal treatment approaches; however, hirudotherapy has not been described in the available literature. To date, we have completed five medicinal leech treatments. Altogether, hirudotherapy led to rapid and substantial relief of symptoms, especially with respect to pain intensity ratings and skin temperature asymmetries. In addition, the patient's active and passive agility of the affected limb improved obviously.

BACKGROUND: The success of salvage procedures for failing digital replants (FR) is poorly documented. We sought to evaluate the success of salvage procedures for FR and factors contributing to successes and failures of replants. METHODS: Adult patients who presented to our center between January 1, 2000 and December 31, 2015, suffered ≥1 digital amputation(s), and underwent digital replantation were included. Preoperative, perioperative, and postoperative details were recorded. Digits were monitored postoperatively via nursing and physician assessments. The presumed reason for failure, details, and outcomes of salvage attempts were recorded for FR. Length of hospital stay and complications were also recorded. RESULTS: Fifty-two patients and 83 digits were included. Fifty-two digits (63%) were compromised (arterial ischemia in 15 digits; venous congestion in 37 digits) and 48 digits had salvage therapy. Twenty-one FR (44%) were salvaged via operative (1 of 2; 50%), nonoperative (19 of 43; 44%), and combined (1 of 3; 33%) therapies. FR patients were more likely than those with successful replants to receive a blood transfusion (52 vs. 23%; p = .009) with more transfused units (3.45 ± 3.30 vs. 0.86 ± 0.95; p = .001). Length of stay was prolonged for FR patients (9 [range: 2-22] vs. 7 [range: 3-19] days; p = .039). Ultimately, 59% (49 of 83) of replants were successful, where 25% (21 of 83) were successfully salvaged. CONCLUSION: Nonoperative and operative salvage therapies improve the rate of replant survival. We suggest close postoperative monitoring of all replants and active salvage interventions for compromised replants in the postoperative period.

BACKGROUND: It is controversial on whether medical leech therapy is effective in improving pain and functional outcome in patients with knee osteoarthritis (OA). Therefore, we perform a meta-analysis from randomized controlled trials (RCTs) to evaluate the efficacy and safety of medical leech therapy in patients with knee OA. MATERIALS AND METHODS: The PubMed, EMBASE, ScienceDirect, and Cochrane Library databases were systematically searched for literature up to January 2018. RCTs involving medical leech therapy in patients with knee OA were included. Two independent reviewers performed independent data abstraction. The I2 statistic was used to assess heterogeneity. A fixed or random effects model was adopted for meta-analysis. All meta-analyses were performed by using STATA 12.0. RESULTS: Four RCTs with 264 patients were included in this meta-analysis. The current meta-analysis showed that there were significant differences in terms of visual analogue scale (VAS) scores and WOMAC scores at 1 week, 4weeks and 7 weeks compared with control groups. However, leech therapy was associated with a significantly higher incidence of adverse events. The overall evidence quality is moderate, which means that further research is likely to significantly change confidence in the effect estimate but may change the estimate. CONCLUSION: Medical leech therapy was associated with a significantly improved outcome in pain relief and functional recovery in patients with symptomatic knee OA. However, given the inherent limitations in the included studies, this conclusion should be interpreted cautiously.

BACKGROUND: Leech therapy has been found to be effective in the treatment of a number of chronic musculoskeletal pain syndromes. Leeches are also often used empirically to treat chronic low back pain, but data from clinical trials have been lacking to date. We therefore conducted the first randomized trial of leech therapy for chronic low back pain. METHODS: Patients with chronic low back pain were randomized to receive either a single session of local treatment with 4-7 leeches or four weekly sessions of exercise therapy (1 hour each) led by a physical therapist. The primary endpoint was a change in average back pain intensity, as measured using a 100-mm visual analog scale (VAS), after 28 days. Secondary end- points included functional impairment (Roland-Morris Disability Questionnaire, Hannover Functional Ability Questionnaire), quality of life (Short-Form Health Questionnaire [SF 36]), pain perception (pain perception scale = Schmerzempfindungsskala [SES]), depressivity (Center for Epidemiological Studies Depression Scale [CES-D]), and analgesic consumption (questionnaire/ diary). Trial visits took place before treatment and on days 28 ± 3 and 56 ± 5 after the start of treatment; the overall duration of the trial was 56 ± 5 days. RESULTS: The mean low back pain score improved from 61.2 ± 15.6 before treatment to 33.1 ± 22.4 on day 28 in the leech ther- apy group (n = 25) and from 61.6 ± 14.8 to 59.8 ± 16.7 in the exercise therapy group (n = 19) (group difference -25.2; 95% con- fidence interval [-41.0; -9.45]; p = 0.0018). Significant benefits of leech therapy were also found at both time points with respect to physical impairment and function as well as physical quality of life. The patients' expectations from treatment were higher in the leech therapy group but did not significantly affect the findings. CONCLUSION: A single session of leech therapy is more effective over the short term in lowering the intensity of pain over the short term and in improving physical function and quality of life over the intermediate term (4 weeks and 8 weeks, respectively). The limitations of this trial are the lack of blinding and the small number of patients. Leech therapy appears to be an effective treat- ment for chronic low back pain.

INTRODUCTION: Medicinal leeches have been part of the therapeutic armamenterium of plastic surgeons for more than 50 years. While their use in hand surgery is a matter of course, their use in salvage of flaps with venous congestion remains facultative depending on teams. MATERIALS AND METHODS: We conducted a systematic review of leech therapy for flap salvage between 1960 and 2015, analyzing 121 articles and subsequently taking into consideration 41 studies. In parallel, we collected data from 43 patients for whom leach therapy had recently been applied in treatment of venous insufficiency in pedicled or free flaps after revision surgery had failed to improve flap vascularization, or in cases where flap revision was not appropriate. The data collected pertained to relevant indications, treatment procedure, efficacy, adjuvant therapies, side effects and complications. RESULTS: For this indication, the success rate of leech therapy ranged from 65 to 85% (83.7% in our series) according to the situations encountered. Optimal frequency of application ranged from 2 to 8hours, while average overall duration ranged from 4 to 10 days. The number of leeches to be applied can be determined depending on volume of the flap. In 50% of the cases reported in the literature, the patients required transfusion. Antibiotic prophylaxis against Aeromonas is highly advisable. A ciprofloxacin and trimethoprim-sulfametoxazole combination currently appears as the most relevant prophylactic antibiotherapy. CONCLUSION: Hirudotherapy is a reliable treatment in cases of patent venous insufficiency of pedicled or free flaps (or when revision surgery is not recommended). Even though the relevant literature is highly heterogeneous, we have attempted to put forward a specific protocol bringing together dosage, delivery route, frequency of administration and appropriate prophylactic antibiotherapy. An algorithm for treatment and management of venous congestion and a practical information sheet have been placed at the disposal of plastic surgery teams.

A universal protocol determining the number of leeches and their application time does not exist. The aim of this study, therefore, is to quantify perfusion dynamics in venous congested tissues after leech application to get more detailed information about changes due to leech-induced skin microcirculation and to evaluate the usability of the Oxygen to See (O2C) device in terms of determining the appropriate number of leeches and the duration of therapy. Twelve patients with the need for leech therapy participated in the study. Perfusion dynamics of the congested tissue was assessed using the O2C device, which determines blood flow (BF), the relative amount of hemoglobin (rHB), and the oxygen saturation (SO2). Measurements were carried out before leech application and on various intervals like 10 minutes, one hour, and three hours after leech application. The leech application effectuated after 10 minutes a nonsignificant perfusion improvement, which further increased after one hour with a significant reduction of the relative amount of hemoglobin and a significant increase of blood flow and oxygen saturation (BF= +56.7%; rHB= -25.5%; SO2= +53.7%). After three hours, the values returned to the levels before leech administration. In two cases, in which further administration of leeches within the measurement period was necessary, no substantial perfusion changes were obtained. The results of this study forms a more precise pattern of microcirculatory changes of leech therapy in congested tissues. According to our measurements a venous drainage improvement can be expected in congested tissue one hour after leech administration. The O2C seems to be a useful method to determine the appropriate number and duration of leech therapy.

While the use of medicinal leech therapy (MLT) in reconstructive and orthopaedic surgery is widely described, post-operative complications related to leeches remain a major concern. Aeromonas spp. strains are involved in the majority of reported cases. As surgical success rate is directly impacted, an adapted antibiotic prophylaxis should be instituted in order to minimize these complications. We assessed pharmaceutical process, microbiological control and related infections in order to provide data and choose the appropriate antibiotherapy for patients requiring MLT. We report a clinical and microbiological study over a 24-month period. Clinical data were collected from patients' database, and microbiological analysis both on leeches' tank water and crushed leeches were performed to characterize isolated strains and their susceptibility to antibiotics. A total of 595 leeches were used to treat 28 patients (12 in plastic surgery and 16 in orthopaedic surgery), and three documented cases of post-operative infections were reported. Aeromonas spp. isolates yielded from 62 % of analyzed batches (75 % of Aeromonas veronii). Eighteen Aeromonas spp. isolates yielded from 23 water samples and three crushed leeches. Isolates were similar in tank and crushed leeches. Strains were susceptible to fluoroquinolones, sulfamethoxazole/trimethoprim, aminosides, and third-generation cephalosporins but resistant to amoxicillin/clavulanic acid and second-generation cephalosporins. According to collected data, routine tank water microbiological analyses are mandatory in order to identify leeches' batches containing resistant strains and to discard them. In this context, the surgeon is able to select an appropriated antibiotic prophylaxis in order to avoid MLT associated serious post-operative complications.
