    Purpose: Our purpose was to report the outcome of endovascular treatment with manual aspiration thrombectomy as the first-line thromboablative method for phlegmasia cerulea dolens. Methods: Between October 2006 and May 2010, seven consecutive patients (5 women, 2 men; age range, 31-80 years) with the diagnosis of phlegmasia cerulea dolens secondary to acute iliofemoral deep venous thrombosis had endovascular treatment with manual aspiration thrombectomy. Catheter-directed thrombolysis and stent placement were used as adjunctive procedures. Phlegmasia was left-sided in five and right-sided in two patients. Results: All patients had associated great saphenous vein thrombosis in addition to iliofemoral deep vein thrombosis (DVT). Aspiration thrombectomy completely removed the thrombus from the popliteal vein to the inferior vena cava (IVC) in all cases. Three patients with May-Thurner syndrome had stent placement in the left common iliac vein. Two patients had early recurrences. Repeated aspiration thrombectomy was unsuccessful in one patient. There were no complications related to the procedure. One patient who had been successfully treated died of sepsis and another patient who had unsuccessful repeated interventions had below-the-knee amputation. Overall, the clinical success and survival rates of patients in this study were 86%. On follow-up, three patients with successful treatment were asymptomatic with no deep venous insufficiency. One of these patients died during the 4-month follow-up period. Two patients had mild ankle swelling with deep venous insufficiency. Conclusions: Manual aspiration thrombectomy with adjunctive use of catheter-directed thrombolysis and stent placement is an effective endovascular treatment method with high clinical success and survival rates for phlegmasia cerulean dolens.

    Venous limb gangrene (VLG) can occur in cancer patients, but the clinical picture and pathogenesis remain uncertain. We identified 10 patients with metastatic cancer (7 pathologically proven) who developed severe venous limb ischemia (phlegmasia/VLG) after initiating treatment of deep-vein thrombosis (DVT); in 8 patients, cancer was not known or suspected at presentation. The patients exhibited a novel, clinically distinct syndrome: warfarin-associated supratherapeutic international normalized ratio (INR; median, 6.5) at onset of limb ischemia, rising platelet count during heparin anticoagulation, and platelet fall after stopping heparin. Despite supratherapeutic INRs, patient plasma contained markedly elevated thrombin-antithrombin (TAT) complex levels (indicating uncontrolled thrombin generation) and protein C (PC) depletion; this profile resembles the greatly elevated TAT/PC activity ratios reported in patients with warfarin-associated VLG complicating heparin-induced thrombocytopenia. Analyses of vitamin K-dependent factors in 6 cancer patients with available serial plasma samples showed that variations in the INR corresponded most closely with changes in factor VII, with a highly collinear relationship between VII and PC. We conclude that venous limb ischemia/gangrene is explained in some cancer patients by profoundly disturbed procoagulant-anticoagulant balance, whereby warfarin fails to block cancer-associated hypercoagulability while nonetheless contributing to severe PC depletion, manifest as a characteristic supratherapeutic INR caused by parallel severe factor VII depletion.

    Sixteen cases of scrotal gangrene are presented. The aetiology, environmental factors and pattern of clinical presentation are described. A total reconstruction of the scrotal sac in all cases as practised in Ife is described. It is advocated that surgeons in the tropics should, in spite of various constraints, try to salvage any infected testis before considering orchidectomy. Infective gangrene of the scrotum is considered a more suitable diagnostic label than Fournier's gangrene. PMID:4095772

    We report the case of a 10-year-old male who developed gangrene of his fingers and toes following severe dengue fever complicated by disseminated intravascular coagulation (DIC). Child developed bilateral dry gangrene of fingers and toes. All the peripheral pulses of the affected limbs were palpable. The child had no history of taking B-blockers, ergot alkaloids or other related medications. Color Doppler of peripheral arterial and venous systems of all limbs indicated normal flow. Blood was positive for D-dimers and fibrin degradation products. The patient was managed with broad spectrum antibiotics, fluid resuscitation, low molecular weight heparin, blood transfusions, fresh frozen plasma and other supportive measures. Peripheral gangrene seen in DIC associated with dengue is very rare and carries a higher mortality. PMID:26755235

    Fournier's gangrene is an acute, rapidly progressive, and potentially fatal, infective necrotizing fasciitis affecting the external genitalia, perineal or perianal regions, which commonly affects men, but can also occur in women and children. There has been an increase in number of cases in recent times. Despite advanced management mortality is still high and averages 20–30%. Early diagnosis using Laboratory Risk Indicator for Necrotizing Fasciitis score and stratification of patients into high risk category using Fournier's Gangrene Severity Index score help in early initiation of treatment. Triple antibiotic combined with radical debridement is the mainstay of treatment. There have been many advances in management of Fournier gangrene including use of vaccum assisted closure and hyperbaric oxygen therapy. With introduction of newer devices like Flexi-Seal, fecal diversion can be done, avoiding colostomy. Reconstruction of perineal defects using skin grafts, flaps, and urethral reconstruction using gracilis flaps can reduce the morbidity associated with FG and provide acceptable functional and aesthetic outcomes.

    When you are ill and consult a physician for his or her expertise, many times laboratory testing is part of the clinical workup. This testing is critical to the physician’s ability to diagnose the patient’s condition. What if testing was not available … because there was no one to do the testing? Although seemingly far-fetched, this scenario could play itself out in the next ten years due to an impending manpower crisis in laboratory medicine. The profession of Medical Technology, also known as Clinical Laboratory Science, is experiencing a shortage of qualified individuals for a variety of reasons – not the least of which is the closure of almost 70% of the schools teaching this critical profession. Health care workers (HCW) rely on accurate and timely clinical laboratory results in order to make decisions for their patients. Because ∼ 70% of patient care decisions are based on clinical laboratory results, it is important to have a well-trained supply of laboratory professionals. This article will give an overview of the situation and the possible causes of this shortage, and pose challenges to our profession as to how this crisis can be averted. Visibility of this profession must be a prime focus of this effort in order for the population in general to be aware of the role Clinical Laboratory Scientists play in the health care consortium. This effort should begin early in the educational process, potentially as early as Middle School (junior high school), bringing awareness of the profession not only to students but to educators as well.

    Clostridial myonecrosis is most often seen in settings of trauma, surgery, malignancy, and other underlying immunocompromised conditions. Since 1953 cases of gas gangrene have been reported in orthopaedic patients including open fractures, closed fractures, and orthopaedic surgeries. We present a case of 55-year-old obese woman who developed rapidly progressive gas gangrene in her right leg accompanied by tibial plateau fracture without skin lacerations. She was diagnosed with clostridial myonecrosis and above-the-knee amputation was carried out. This patient made full recovery within three weeks of the initial episode. We identified a total of 50 cases of gas gangrene in orthopaedic patients. Several factors, if available, were analyzed for each case: age, cause of injury, fracture location, pathogen, and outcome. Based on our case report and the literature review, emergency clinicians should be aware of this severe and potentially fatal infectious disease and should not delay treatment or prompt orthopedic surgery consultation.

    Leg ulcers are often complicated in patients with rheumatoid arthritis (RA), however, the etiology is multifactorial. We examined the cases of leg ulceration or gangrene in seven RA patients who were hospitalized over the past 3 years. One patient was diagnosed as having pyoderma gangrenosum. Although vasculitis was suspected in three patients, no histological evidence was obtained from the skin specimens. In these patients, angiography revealed the stenosis or occlusion of digital arteries. In the remaining three patients, leg ulcers were considered to be due to venous insufficiency. Treatment should be chosen depending on the causes of leg ulcers. PMID:24304368

    Gas gangrene is a general toxi-infection, which is mostly the result of a contamination of the muscles from traumatic or post-operative origin. Muscular necrosis expands very quickly, causes mutilations, hits several organs and leads to shock. The spontaneous evolution is mostly mortal within a couple of hours. For a long time it was considered to be a typical military disease: during World War I some 100,000 German soldiers lost their lives as a direct result. It represented then 10 to 12% of all deads of wounds. This mortality rate decreased between 0.3 and 1.5% during World War II and to 0.016% during the Vietnam WAr. Although gas gangrene is no longer a typical military disease, the holy principles of war surgery must be respected. All war wounds, and in particular those caused by high velocity missiles are contaminated, a.o. by clostridium spores. An immediate suture of those wounds, through which necrotized tissue is covered (an ideal anaerobic environment), furthers the development of gas gangrene. The only prevention consists of debriding those wounds, leaving them opened, followed by a delayed primary suture between the 4th and 7th day after the debridement. Not properly treated will gas gangrene always be mortal. In some instances, an emergency amputation will be the only way to save the patient's life. Antibiotherapy, hyperbaric oxygenotherapy and most of all surgery from the medical triade which is imperative to treat this disease. Thanks to these measures, the mortality rate decreased from 70% before 1960 to 41%. Nonetheless the most important act remains the early, complete, rational and rigorous debridement of the wounds. Far from being an obsolete attitude, this is one of humility, wisdom ... and with future prospects. PMID:3716723

    Gangrenous pyoderma (GP) is a rare infectious disease typically manifesting itself by utterly painful crural ulcers. Currently, the disease is considered to be most likely of an autoimmune origin. The author presents herein a case report describing key diagnostic and treatment decisions regarding a 30-year-old woman suffering from extensive crural ulcers. Of special interest was the finding that this patient's ultrasonographic duplex scanning showed the signs corresponding to postthrombotic disease. However, conventional treatment of venous trophic ulcers turned out inefficient. The woman was diagnosed as having GP. Topical therapy with corticosteroid drugs (combined with autodermoplasty and compression therapy) made it possible to achieve complete epithelisation of ulcers. Thus, should conventional treatment of venous trophic ulcers result in the patient's failure to respond properly, it is necessary to take into consideration the probability of gangrenous pyoderma.

    Fournier gangrene is a very rare and a rapidly progressing, polymicrobial necrotizing faciitis or myonecrosis of the perineal, perianal and genital regions, with a high mortality rate. Infection is associated with superficial traum, urological and colorectal diseases and operations. The most commonly found bacteria are Escherichia coli followed by Bacteroides and streptococcal species. Diabetes mellitus, alcoholism, and immunosuppression are perpetuating co-factors. Fournier's gangrene complicating inflammatory bowel disease has been reported in three patients so far, two with Crohn's disease. A 78-year-old man diagnosed with ulcerative pancolitis was referred for fever, and painful perianal and scrotal swelling after perianal surgery for a horseshoe-type perianal abscess. Since bowel disease diagnosis, patient was on mesalazine and achieved long-term remission. Perianal abscess occurred suddenly one week before perianal surgery without any evidence of pre-existing fistula or other abnormalities. Physical examination showed extensive edema and crepitus of perineum and genitalia and patient had symptoms of significant toxicity. The diagnosis of Fournier's gangrene was made and patient underwent emergency surgery with extensive surgical debridement of the scrotal and perianal area and Hartman procedure with a diverting colostomy. In addition, patient started on therapy with mesalazine 3gr, methylprednisolone 16 mg, parenteral nutrition and broad spectrum of antibiotics. Two days after the first operation the patient needed a second operation for perianal debridement. On the fourth day, blood cultures showed E. coli. Patient had an uneventful recovery and was discharged after 34 days of hospitalization. On follow up, disease review is scheduled and colostomy closure is planned. PMID:21122507

    Radionuclide hepatobiliary imaging with Tc-99m IDA is a useful procedure for the diagnosis of acute cholecystitis. Visualization of the gallbladder essentially rules out acute cholecystitis. Nonvisualization suggest acute cholecystitis but may also be associated with chronic gallbladder disease or other conditions. The authors recently observed five patients in whom a rim of increased parenchymal liver activity was seen adjacent to the gallbladder fossa. All five patients had acute gangrenous cholecystitis. The rim of increased activity appears to be a useful secondary sign of acute cholecystitis.

    Fournier's Gangrene is a rapidly progressive necrotizing fasciitis of the groin, perianal and perineal region that is often polymicrobial in nature, often averaging 3 species of bacteria per patient. The typical infection can be due to a host of microbes, including gram positive, gram negative and anaerobic species including. Many of the causative organisms are found in the normal microbial flora of the perineum. Therefore, Fourniers is an opportunistic infection most commonly affecting the immunosuppressed. The majority of Fournier's gangrene are bacterial; however there have been cases of fungal Fournier's gangrene reported in the literature. PMID:26793562

This patient was treated with a radical debridement of his perineum at presentation and subsequently reconstructed with split thickness skin grafting. This is an unusual aetiology of necrotizing fasciitis with only one other case reported in the literature. This serves to emphasize to physicians that acute pancreatitis is a potential source when investigating and treating patients with Fournier's Gangrene. PMID:27150281

    Pulmonary gangrene, a rare complication of pneumonia occurs when vascular thrombosis leads to necrosis of a large portion of lung. The devitalized lung is then sloughed into a cavity, resulting in a characteristic radiographic appearance. The previously reported cases of pulmonary gangrene have been associated with either bacterial or tuberculous pneumonia; the authors describe a case resulting from mucormycosis. In addition to the plain-film findings, the computed tomographic (CT) appearance is described.

    To share experience on the presentation and management of 4 cases of isolated penile Fournier's gangrene. Clinical and demographic data of four patients with isolated penile Fournier's gangrene seen over an 8-year period (January 2006-December 2013) were reviewed. All patients had intravenous fluid resuscitation, emergency surgical debridement, and broad-spectrum intravenous antibiotics. Fournier's gangrene of the penis was, respectively, due to long segment anterior urethral stricture, penile edema from poorly controlled congestive cardiac failure, penile abrasion from oral sex and idiopathic. The mean age of the patients was 34.3 ± 5.6 years. One patient with urethral stricture had urinary tract infection. The patients presented with a prodromal period of genital pain and fever followed by genital swelling, gangrene, and ulceration. The most common wound swab isolates were Staphylococcus aureus and Escherichia coli. Only the skin and dartos fascia were affected with sparing of the corporal cylinders. Mean hospital stay was 17.3 ± 3.0 days and mean Fournier's gangrene severity index (FGSI) was 4.0 ± 0.8. Wound closure was achieved by split skin grafting in 2 patients, delayed primary closure in the third and healing by secondary intention in the fourth patient. Subjectively assessed erectile function was preserved in all four patients. Isolated Fournier's gangrene of the penis is very rare. It is associated with low FGSI and sparing of the three corporal cylinders. It may rarely follow oral sexual practice. PMID:27022814

    Fournier's gangrene (FG) is a rare but life threatening disease. Although originally thought to be an idiopathic process, FG has been shown to have a predilection for patients with diabetes as well as long term alcohol misuse; however, it can also affect patients with non‐obvious immune compromise. The nidus is usually located in the genitourinary tract, lower gastrointestinal tract, or skin. FG is a mixed infection caused by both aerobic and anaerobic bacterial flora. The development and progression of the gangrene is often fulminating and can rapidly cause multiple organ failure and death. Because of potential complications, it is important to diagnose the disease process as early as possible Although antibiotics and aggressive debridement have been broadly accepted as the standard treatment, the death rate remains high.

    Fournier's gangrene is traditionally treated with prompt surgical debridement and in many cases a diverting colostomy is also fashioned during the same procedure. We present four cases where stoma formation was delayed until the second look procedure. The physiological states at the time of either procedure were compared using POSSUM. The results showed an improvement in the physiological condition in all patients at the time of the second operation, suggesting that a delay can potentially improve prognosis in such cases.

    Bioprinting provides a fully automated and advanced platform that facilitates the simultaneous and highly specific deposition of multiple types of skin cells and biomaterials, a process that is lacking in conventional skin tissue-engineering approaches. Here, we provide a realistic, current overview of skin bioprinting, distinguishing facts from myths. We present an in-depth analysis of both current skin bioprinting works and the cellular and matrix components of native human skin. We also highlight current limitations and achievements, followed by design considerations and a future outlook for skin bioprinting. The potential of bioprinting with converging opportunities in biology, material, and computational design will eventually facilitate the fabrication of improved tissue-engineered (TE) skin constructs, making bioprinting skin an impending reality.

    Fournier's gangrene is the necrotizing fasciitis of perianal, genitourinary, and perineal regions. Herein, we present a case of scrotal Fournier's gangrene as a postoperative complication of inguinal hernia repair. A 51-year-old male with giant indirect hernia is presented. Patient underwent inguinal hernia repair, and after an unproblematic recovery period, he was discharged. He applied to our outpatient clinic on the fifth day with swollen and painful scrotum and it turned out to be Fournier's gangrene. Polypropylene mesh was not infected. Patient recovered and was discharged after repeated debridements. Basic principles in treatment of Fournier's gangrene are comprised of initial resuscitation, broad-spectrum antibiotics therapy, and early aggressive debridement. In the management of presented case, aggressive debridement was made right after diagnosis and broad-spectrum antibiotics were given to the hemodynamically stable patient. In these circumstances, the important question is whether we could prevent occurrence of Fournier's gangrene. PMID:25506030

    Fournier's gangrene is a necrotizing infection of skin and soft tissue of the perineum. Several sources of contamination have been described: cutaneous, urological or anorectal. Anatomy of the perineum helps in the prediction of the extension of the infection. The bacterial flora (usually mixed aero-anaerobic flora) depends on the source of infection: gram-positive cocci (skin source) combined with gram-negative bacilli and anaerobes (urological or anorectal source). CT scan and echography are useful tools for the diagnosis without delaying surgery. In the diagnostic procedure and the management, proctological examination, retrograde uretrography, bowel and urine derivation should be discussed. PMID:16675183

    Venous disorders causing a permanent increase in venous pressure are by far the most frequent reason for ulcers of the lower extremity. With a prevalence of 1 % in the general population rising to 4 % in the elderly over 80 and its chronic character, 1 % of healthcare budgets of the western world are spent on treatment of venous ulcers. A thorough investigation of the underlying venous disorder is the prerequisite for a differenciated therapy. This should comprise elimination of venous reflux as well as local wound management. Chronic ulcers can successfully be treated by shave therapy and split skin grafting. Compression therapy is a basic measure not only in venous ulcer treatment but also in prevention of ulcer recurrence. Differential diagnosis which have to be considered are arterial ulcers, vasculitis and neoplasms. PMID:27405863

    Gaseous gangrene is an infection with anaerobies germs characterized by gaseous infiltration of soft tissues with quick and serious damage to the general state. Known in war time, it rages also in civilian practice. Two etiologies are dominating: post-trauma gaseous gangrenes, post-surgery gaseous gangrenes. Among post-trauma gaseous gangrenes, the ones on departure of inferior members are the most frequent arising from fractures or from luxations open or closed. Localisation on superior limbs is scarce, specially after soft parts' trauma. We report three cases of superior limbs' gaseous gangrene after seemingly benign trauma. Diagnosis has been set by the clinical surgery, and the presence of gas bubbles at soft tissues' radiography. It didn't exist any favorising agent such as diabetes, arterial insufficiency, intercurrent disease treated with corticoïdes or with immuno-depressors. Bacteriological levyings have not put the causal germ in evidence, this is due to levying conditions. Evolution of gaseous gangrene depends on quickness of diagnosis and treatment. This one includes surgical flattening, discharge's incisions and excisions of devitalized tissues, as well as antibiotherapy with 20 000 to 60 000 U penicilline by parenteral way. We didn't need appeal to hyperbare oxygenotherapy. Simple procedures of secondary repair surgery were sufficient to restoration of a normal function. Gaseous gangrene is a real surgical urgency, even without bacteriological proof. PMID:6529302

    Skin and soft tissue infections of the lower limbs are quite common and can at times progress rapidly to become both limb and life-threatening infections. Muscular infections usually occur in areas of the body that have been compromised or injured by a foreign body, trauma, ischaemia, injection of illicit drugs, malignancy or surgery. Gas gangrene is one such limb-threatening infection. The gas-forming infection can be clostridial or non-clostridial. Clostridia are the main causative organism of the gas gangrene. Non-clostridial gas gangrene is a rare condition and is known to be associated with high mortality. Here, we report one such rare case where a middle-aged man succumbed to non-clostridial gas gangrene after he was administered an intramuscular injection. The case was registered as a suspicious death by the police and the body was subjected to medico legal autopsy. PMID:26672772

    We report a rare case that highlights acute pancreatitis as the protagonist of Fournier’s Gangrene. This patient was treated with a radical debridement of his perineum at presentation and subsequently reconstructed with split thickness skin grafting. This is an unusual aetiology of necrotizing fasciitis with only one other case reported in the literature. This serves to emphasize to physicians that acute pancreatitis is a potential source when investigating and treating patients with Fournier’s Gangrene. PMID:27150281

    Takayasu's arteritis (TA) is a chronic inflammatory disease of medium and large vessels, mainly involving the aorta and its major branches. TA may have diverse clinical presentation including claudication, stroke, asymmetric pulse or blood pressure. However, the association of TA with digital gangrene is a rare entity. Here, we report a case of a 40-year-old woman who presented with digital gangrene of the right hand, which on workup was diagnosed as a case of TA. PMID:23314451

    Venous leg ulcers are the most frequent form of wounds seen in patients. This article presents an overview on some practical aspects concerning diagnosis, differential diagnosis and treatment. Duplex ultrasound investigations are essential to ascertain the diagnosis of the underlying venous pathology and to treat venous refluxes. Differential diagnosis includes mainly other vascular lesions (arterial, microcirculatory causes), hematologic and metabolic diseases, trauma, infection, malignancies. Patients with superficial venous incompetence may benefit from endovenous or surgical reflux abolition diagnosed by Duplex ultrasound. The most important basic component of the management is compression therapy, for which we prefer materials with low elasticity applied with high initial pressure (short-stretch bandages and Velcro-strap devices). Local treatment should be simple, absorbing and not sticky dressings keeping adequate moisture balance after debridement of necrotic tissue and biofilms are preferred. After the ulcer is healed compression therapy should be continued in order to prevent recurrence. PMID:26236636

    Background: Gangrenous cholecystitis (GC) is considered a more severe form of acute cholecystitis. The risk factors associated with this condition and its impact on morbidity and mortality compared with those of non-gangrenous acute cholecystitis (NGAC) are poorly defined and based largely on findings from older studies. Methods: Patients with histologically confirmed acute cholecystitis treated in specialized units in a tertiary hospital between 2005 and 2010 were identified from a prospectively maintained database. Data were reviewed retrospectively and patients with GC were compared with those with NGAC. Results: A total of 184 patients with NGAC and 106 with GC were identified. The risk factors associated with GC included older age (69 years vs. 57 years; P = 0.001), diabetes (19% vs. 10%; P = 0.049), temperature of >38 °C (36% vs. 16%; P < 0.001), tachycardia (31% vs. 15%; P = 0.002), detection of muscle rigidity on examination (27% vs. 12%; P = 0.01) and greater elevations in white cell count (WCC) (13.4 × 109/l vs. 10.7 × 109/l; P < 0.001), C-reactive protein (CRP) (94 mg/l vs. 17 mg/l; P = 0.001), bilirubin (19 µmol/l vs. 17 µmol/l; P = 0.029), urea (5.3 mmol/l vs. 4.7 mmol/l; P = 0.016) and creatinine (82 µmol/l vs. 74 µmol/l; P = 0.001). The time from admission to operation in days was greater in the GC group (median = 1 day, range: 0–14 days vs. median = 1 day, range: 0–10 days; P = 0.029). There was no overall difference in complication rates between the GC and NGAC groups (22% vs. 14%; P = 0.102). There was a lower incidence of common bile duct stones in the GC group (5% vs. 13%; P = 0.017). Gangrenous cholecystitis was associated with increased mortality (4% vs. 0%; P = 0.017), but this was not an independent risk factor on multivariate analysis. Conclusions: Gangrenous cholecystitis has certain clinical features and associated laboratory findings that may help to differentiate it from NGAC. It is not associated with an overall increase in

    A 45-year-old man presented with a 4-day history of high-grade fever with rigours and a 2-day history of painful bluish black discolouration of extremities (acrocyanosis). He was haemodynamically stable and all peripheral pulses palpable, but the extremities were cold with gangrene involving bilateral fingers and toes. Mild splenomegaly was present on abdominal examination but rest of the physical examinations were normal. On investigating he was found to have anaemia, thrombocytopaenia with gametocytes of Plasmodium falciparum on peripheral blood smear. His blood was uncoagulable during performance of prothrombin time with a raised D-dimer. Oxygen saturation was normal and the arterial Doppler test showed reduced blood flow to the extremities. A diagnosis of complicated P. falciparum malaria with disseminated intravascular coagulation (DIC) leading to symmetrical peripheral gangrene was performed. Artemisinin combination therapy was started and heparin was given for DIC. A final line of demarcation of gangrene started forming by 12th day. PMID:24862424

    Fournier’s gangrene, an obliterative endarteritis of the subcutaneous arteries resulting in gangrene of the overlying skin, is a rare but severe infective necrotizing fasciitis of the external genitalia. Mainly associated with men and those over the age of 50, Fournier’s gangrene has been shown to have a predilection for patients with diabetes as well as people who are long-term alcohol misusers. The nidus for the synergistic polymicrobial infection is usually located in the genitourinary tract, lower gastointestinal tract or skin. Early diagnosis remains imperative as rapid progression of the gangrene can lead to multiorgan failure and death. The diagnosis is often made clinically, although radiography can be helpful when the diagnosis or the extent of the disease is difficult to discern. The Laboratory Risk Indicator for Necrotizing Fasciitis score can be used to stratify patients into low, moderate or high risk and the Fournier’s Gangrene Severity Index (FGSI) can also be used to determine the severity and prognosis of Fournier’s gangrene. Mainstays of treatment include rapid and aggressive surgical debridement of necrotized tissue, hemodynamic support with urgent resuscitation with fluids, and broad-spectrum parental antibiotics. After initial radical debridement, open wounds are generally managed with sterile dressings and negative-pressure wound therapy. In cases of severe perineal involvement, colostomy has been used for fecal diversion or alternatively, the Flexi-Seal Fecal Management System can be utilized to prevent fecal contamination of the wound. After extensive debridement, many patients sustain significant defects of the skin and soft tissue, creating a need for reconstructive surgery for satisfactory functional and cosmetic results.

    The function of an arteriovenous (av) fistula for haemodialysis may be complicated by manifestation of peripheral venous hypertension, which results from the arterial blood flow through the venous system into the periphery of the upper extremity. Its development is most typically caused by a proximal forearm av-fistula, as, in addition to the desirable arterialisation of the subcutaneous venous system of the arm, arterialisation of the venous system of the forearm and the hand may occur and possibly promote the development of venous hypertension, which may in the extreme result in gangrene of the fingers. Awareness of these problems as well as of the necessity of their surgical solution is essential for doctors dealing with haemodialysis. PMID:15523553

    Patients presented for amputation mostly have chronic limb ischaemia caused by atherosclerosis, with signs of severe arterial insufficiency including rest pain, non-healing skin lesions, ulceration or gangrene. Foot infections, especially in diabetic patients, are often multimicrobial, deeply invasive and frequently require aggressive measures, like debridement and drainage or partial open forefoot amputation in addition to broad-spectrum antibiotics, in patients with critical limb ischaemia and limited necrosis and forefoot gangrene, distal bypass surgery is the treatment of choice. The main question is whether amputation should be performed simultaneously or in a secondary stage. Our own experience deals with 342 femorocrural and femoropedal bypass grafts for the treatment of critical limb ischaemia. The results showed no significant difference in graft patency between crural and pedal grafts. Clinical factors like diabetes mellitus, poor distal run-off and site of the distal anastomosis had no adverse effect on the functioning and patency of the graft. In this series we found that in diabetic patients significantly more amputations were required because of persistent foot infection. Since in these patients amputation was performed in a secondary stage, we changed our policy to simultaneous amputation. After completion of the bypass, closure and coverage of all the wounds, the gangrenous part is amputated. In case of deep, wet or infectious gangrene of the forefoot, an open transmetatarsal amputation is performed. Using this approach we have further increased limb-salvage and especially the number of usuable limbs. PMID:8713389

    Combined arterial and venous thrombosis in patients with ulcerative colitis is a rare extra vascular manifestation, which motivated the current report. Increased coagulability is a recognised feature of ulcerative colitis with frequency increasing during flares. We report the case of a 42-year-old lady who was a diagnosed case of ulcerative colitis, currently in remission. She presented with swelling followed by discolouration of left lower limb which later was diagnosed as deep venous thrombosis combined with femoral and popliteal artery thrombosis. This led to wet gangrene of the limb, sepsis, septic shock and death despite aggressive management with heparin infusion, ionotropes, and parenteral antibiotics therapy. PMID:27190869

    Venous thromboembolism (VTE) encompasses deep-vein thrombosis (DVT) and pulmonary embolism. VTE is the leading cause of lost disability-adjusted life years and the third leading cause of cardiovascular death in the world. DVT leads to post-thrombotic syndrome, whereas pulmonary embolism can cause chronic pulmonary hypertension, both of which reduce quality of life. Genetic and acquired risk factors for thrombosis include non-O blood groups, factor V Leiden mutation, oral contraceptive use, hormone replacement therapy, advanced age, surgery, hospitalization and long-haul travel. A combination of blood stasis, plasma hypercoagulability and endothelial dysfunction is thought to trigger thrombosis, which starts most often in the valve pockets of large veins. Animal studies have revealed pathogenic roles for leukocytes, platelets, tissue factor-positive microvesicles, neutrophil extracellular traps and factors XI and XII. Diagnosis of VTE requires testing and exclusion of other pathologies, and typically involves laboratory measures (such as D-dimer) and diagnostic imaging. VTE is treated with anticoagulants and occasionally with thrombolytics to prevent thrombus extension and to reduce thrombus size. Anticoagulants are also used to reduce recurrence. New therapies with improved safety profiles are needed to prevent and treat venous thrombosis. For an illustrated summary of this Primer, visit: http://go.nature.com/8ZyCuY. PMID:27189130

    A 68-year-old man was hospitalized with the complaints of left back pain and fever. He had a history of using steroids to treat uveitis for about thirty years. Computed tomography on the chest demonstrated an impending rupture in an aortic arch aneurysm, which was consequently surgically excised. Candida albicans was identified in the wall of the aneurysm, so fluconazole and itraconazole were administered. The patient was discharged at 120 days after surgery without recrudescence of the candida. To our knowledge, this is the fifteenth case of a successfully treated aneurysm caused by candida infection.

    AIM: To determine the significance of enterostomy in the emergency management of Fournier gangrene. METHODS: The clinical data of 51 patients (49 men and 2 women) with Fournier gangrene who were treated at our hospital over the past 12 years were retrospectively analyzed. The patients were divided into two groups according the surgical technique performed: enterostomy combined with debridement (the enterostomy group, n = 28) or debridement alone (the control group, n = 23). Patients in the enterostomy group received thorough debridement during surgery and adequate local drainage after surgery, as well as administration of broad-spectrum antibiotics. The clinical data and outcomes in both groups were analyzed. RESULTS: The surgical procedures were successful in both patient groups. In the enterostomy group, 10 (35.8%) patients required skin grafting with a total of six debridement procedures. While in the control group, six (26.1%) patients required four debridement procedures. However, this difference was not statistically significant. Following surgery, the time to normal body temperature (6 d vs 8 d, P < 0.05) and average length of hospital stay (14.3 ± 7.8 d vs 20.1 ± 8.9 d, P < 0.05) were shorter in the enterostomy group. The case fatality rate was lower in the enterostomy group than that in the control group (3.6% vs 21.7%, P < 0.05). CONCLUSION: Enterostomy can decrease the case fatality rate of patients with Fournier gangrene. PMID:24976731

    Fournier's gangrene is a fearsome disease with a bad prognosis and a mortality rate ranging between 10 and 80% according to the literature. It is extensive in 13 to 54% of cases. Up to date, cervico-facial extension has never been reported. We describe the case of a 51-year-old overweighed woman with a history of type 2 diabetes and a narrow lumbar canal who was referred to our institution for significant fatigue and increasingly painful legs. A diagnosis of Fournier's gangrene was made after correlating the physical findings with the results of a full body scan. Diffuse subcutaneous emphysema involving the face, neck, mediastinum, abdominal wall, right buttock, perineum and the right thigh was identified. Treatment included multiple surgical debridements, admission to intensive care unit, and an efficient antibiotic therapy that enabled preservation of the patient's life. To our knowledge, this is the first case of cervical and mediastinal extension of Fournier's gangrene to be reported. No clear guidelines exit on the management of this complication (cervico-facial and mediastinal drainage). We share our experience of this unusual case. PMID:25766003

    A mobile caecum and ascending colon is an uncommon congenital disorder, and it is even rarer as the cause of an acute abdomen during childhood. This report presents the case of a 6-year-old boy with acute gangrenous appendicitis with a mobile caecum and ascending colon. Data from the surgical course, as well as laboratory and imaging studies, were acquired and carefully examined. Emergency ultrasound (US) was performed and revealed no signs of appendicitis in the right lower quadrant. Serial imaging study, including non-enhanced computed tomography (CT), was performed. An imaging study identified epigastric appendicitis with mobile caecum. Surgery was executed under general anesthesia with a median incision extending from the epigastrium to the suprapubic region. The caecum was mobile and placed in the right epigastric area, next to the left lobe of the liver and gallbladder. The gangrenous appendix was discovered posterior to the caecum and transverse colon, enlarging to the left upper quadrant. Appendectomy was executed, the gangrenous appendix was confirmed pathologically, and the patient was released 4 days later. In the US, if there are unusual clinical findings or no findings in patients with abdominal pain, CT is beneficial in determining the location of the caecum and appendix and preventing misdiagnosis in children.

    The development of ischemic gangrene of the penis following implantation of prosthesis is unusual, and very few cases are available in the literature. As a result, no established treatment protocol is available. We report our experience within a case of gangrene of the glans following implantation of a three-component prosthesis. We present a 53-year-old male, smoker with diabetes and hypercholesterolemia, who underwent surgery for the insertion of a penile prosthesis with 3 components to correct his erectile dysfunction and severe Peyronie's disease. The procedure was carried out without incidents. During the postoperative period, the patient began to complain from penile and perineal pain. He developed avascular necrosis of the glans. The necrosed area was excised. Four weeks later, he developed fever and perineal pain arriving to the emergency room with the prosthesis extruding through the glans. He had emergency surgery to remove the prosthesis plus surgical lavage and was prescribed broad-spectrum antibiotic therapy. Four weeks later, the penis was completely revascularized and reepithelialized. Ischemic gangrene following penile prosthesis implantation takes place in patients with poor peripheral vascularisation. Diabetes mellitus has been the common denominator to all of the reported cases. PMID:23956919

    Surgical correction of deep venous reflux is a valuable adjunct in treatment of selected patient with lower limb venous ulcer. Deep venous obstruction and superficial reflux is must be corrected first. Sustained venous ulcer healing and reduced ambulatory venous hypertension can be achieved in patients with both primary and secondary deep venous insufficiency. When direct valve repair is possible, valvuloplasty is the best option, but when this is not feasible, other techniques can be used, including femoral vein transposition into the great saphenous vein, vein valve transplant, neovalve construction, or nonautologous artificial venous valve.

    Objective: Percutaneous osteosynthesis plus cementoplasty (POPC) is a minimally invasive technique that has never been reported before and that we have prospectively evaluated for patients with impending pathological fracture of the proximal femur. Methods: We performed POPC in 12 patients (3 males, 9 females) with metastasis of the proximal femur with a high risk of fracture (Mirels' score {>=}8) between February 2010 and July 2011. Patients were not candidates for standard surgical stabilization. We analyzed the feasibility, duration, and complication of the procedure, the risk of fracture, the decrease in pain (Visual Analog Scale, VAS), and length of stay in hospital. Data were prospectively collected in all patients. Results: The mean Mirels' score was 9.8 {+-} 1.2 (range, 8-11). The technical success was 100%. POPC was performed under general anesthesia (n = 6) or conscious sedation (n = 6). The mean duration was 110 {+-} 43 (range, 60-180) minutes. All patients stood up and walked the second day after the procedure. The average length of stay in the hospital was 4 {+-} 1.6 (range, 2-7) days. We experienced two hematomas in two patients and no thromboembolic complication. For symptomatic patients (n = 8), VAS decreased from 6.5/10 (range, 2-9) before treatment to 1/10 (range, 0-3) 1 month after. No fracture occurred after a median follow-up of 145 (range, 12-608) days. Conclusions: POPC for impending pathological fracture of the proximal femur seems to be a promising alternative for cancer patients who are not candidates for surgical stabilization. Further studies are required to confirm this preliminary experience.

    PubMed

    Battin, Jacques

    2010-01-01

    The frequent epidemics of ergotism were called Holy Fire or st-Antony's Fire in the Middle Ages, because of the burning sensations resulting in gangrene of limbs. It was caused by eating rye bread contaminated with the fungus Claviceps purpurea. The hospitable Order of st-Antony was founded near Vienne in France with 300 establishements in Europe until 1777. In coptic and byzantine art st-Antony is the father of the monks, whereas in Occident he is the the master of fire, thaumaturgic, resulting a very important iconography in statuary and painworks in all regions, especially in Lorraine, the catholic and tridentin Lotharingia and in Corsica thanks to the franciscan pastoral. Woodcuts show not only the temptations of st-Antony, with strange and diabolic scenes, patients with gangrenous limbs. Germanic woodcuts of the 15th century show patients with different stages of ergotism and hands and feet like ex-voto. Triptycs of H. Bosch and M. Gunewald are witnesses of the frequency and seriousness of this disease still at the beginning of the 16th century. PMID:21598563

    Purpose. Fournier's gangrene is a fulminant and destructive inflammation of the scrotum, penis, and perineum. The objective of this study was to compare 2 different approaches to wound management after aggressive surgical debridement. Methods. Data from 14 patients with Fournier's gangrene were retrospectively collected (2005–2011). Once the patients were stabilized following surgery, they were treated with either daily antiseptic (povidone iodine) dressings (group I, n = 6) or dressings with dakin's solution (sodium hypochloride) (group II, n = 8). Results. The mean age of the patients was 68.2 ± 7.8 (55–75) years in group I and 66.9 ± 10.2 (51–79) years in group II. Length of hospital stay was 13 ± 3.5 (7–16) days in group I and 8.9 ± 3.0 (4–12) days in group II (P < 0.05). The number and rate of mortality was 1/6 (16.7%) in group I, and 1/8 (12.5%) in group II. Conclusions. The hospitalization time can be reduced with the use of dakin's solution for the dressings in the treatment of FG. Also, dressings with dakin's solution seems to have favorable effects on morbidity and mortality. Consequently dakin's solution may alter the treatment of this disastrous disease by reducing cost, morbidity and mortality. PMID:22567424

    Penile gangrene associated with chronic renal failure is very uncommon. A 52-year-old man with diabetes mellitus, diffuse atherosclerosis, ischemic cardiomyopathy and end-stage renal disease presented with blackening of distal penis for 10 days. His general condition was poor and gangrene of prepuce and glans was noted. Doppler and magnetic-resonance angiography revealed bilateral internal iliac artery obstruction. He underwent trocar suprapubic cystostomy and was planned for partial penectomy. But he died of severe diabetic complications in the interim period. Penile gangrene is a manifestation of widespread vascular calcifications associated with end-stage renal disease and is a marker of poor prognosis. PMID:19675807

    Inflammatory bowel diseases can commonly present many cutaneous lesions which can contribute to the diagnosis of the disease or its activity. The most frequent cutaneous or mucocutaneous manifestations suggesting ulcerative rectocolitis activity are erythema nodosum (3-10%), pyoderma gangrenosum (5-12%) and aphthous stomatitis (4%). Other reactive skin manifestations related to immunological mechanisms associated with the inflammatory bowel disease are: Sweet's syndrome, arthritis-dermatitis syndrome associated with inflammatory bowel disease and leukocytoclastic vasculitis. We describe the case of a young man with diagnosis of ulcerative rectocolitis, which presented an extensive cutaneous gangrene secondary to microvascular thrombosis. The case represents a dermatologic rarity and should be recognized as a cutaneous manifestation related to the hypercoagulability state observed in the disease's activity. PMID:25387503

    Inflammatory bowel diseases can commonly present many cutaneous lesions which can contribute to the diagnosis of the disease or its activity. The most frequent cutaneous or mucocutaneous manifestations suggesting ulcerative rectocolitis activity are erythema nodosum (3-10%), pyoderma gangrenosum (5-12%) and aphthous stomatitis (4%). Other reactive skin manifestations related to immunological mechanisms associated with the inflammatory bowel disease are: Sweet's syndrome, arthritis-dermatitis syndrome associated with inflammatory bowel disease and leukocytoclastic vasculitis. We describe the case of a young man with diagnosis of ulcerative rectocolitis, which presented an extensive cutaneous gangrene secondary to microvascular thrombosis. The case represents a dermatologic rarity and should be recognized as a cutaneous manifestation related to the hypercoagulability state observed in the disease's activity. PMID:25387503

    Background: Fourniers gangrene caused by synergic aerobic and anaerobic organism is a life threatening disorder. Methods: The medical records of 8 among 839 patients admitted to imam ali general hospital Zahedan university of Medical Sciences with fourniers gangrene during the 10 months period between 2012 and 2013 were reviewed. Results: The most common etiology and presentation were abscess and perianal pain respectively. Mixed bacterial flora was common finding in patient. Single debridement was carried out in 2 patients and repeated procedure was needed in 6. Conclusion: This disease is characterized with high mortality of up to 75% but in our study the rate was 37.5%. In other studies diabetes mellitus was found to be the common condition related to fourniers gangrene but in our study the common etiology was perianal abscess. Fourniers gangrene should be rule out in any patient with perianal pain and flulike, swelling skin. PMID:26034725

    Juvenile gangrenous vasculitis of the scrotum was described by Piñol et al in 1974 as a unique variant of scrotal gangrene of unknown origin, occurring exclusively in young individuals. It was characterized by an acute onset of skin ulcers undergoing complete resolution after appropriate therapy, with no relapses. We present a typical case of this extremely rare disease affecting a 16-year-old boy in whom the scrotal ulcerations were preceded by an episode of pharyngitis with fever. The condition promptly regressed after administration of intramuscular betamethasone in combination with oral ciprofloxacin. According to Piñol et al, juvenile gangrenous vasculitis of the scrotum, although poorly known to dermatologists, should be regarded as a distinctive entity within the wide group of scrotal gangrenes. On the other hand, the hypothesis that this condition may well represent a variant of pyoderma gangrenosum is discussed. PMID:16843125

    1984-04-01

    Several unusual cases of cerebral venous angiomas as well as some characteristic cases are reported. The characteristic angiographic feature is that of a collection of dilated medullary veins draining into a single large draining vein, which appears first in the early venous phase and persists into the late venous phase of the arteriogram. Computed tomography (CT) was abnormal in 12/13 cases. The draining vein was the most common abnormality identified on CT. Coronal and sagittal reconstruction may be helpful in demonstrating the draining vein. A case of large twin venous angiomas, a case of hemorrhage from a venous angioma, and a case of a venous angioma with an incidentally associated glioblastoma are presented.

    Compression therapy is considered to be the most important conservative treatment of venous leg ulcers. Until a few years ago, compression bandages were regarded as first-line therapy of venous leg ulcers. However, to date medical compression stockings are the first choice of treatment. With respect to compression therapy of venous leg ulcers the following statements are widely accepted: 1. Compression improves the healing of ulcers when compared with no compression; 2. Multicomponent compression systems are more effective than single-component compression systems; 3. High compression is more effective than lower compression; 4. Medical compression stockings are more effective than compression with short stretch bandages. Healed venous leg ulcers show a high relapse rate without ongoing treatment. The use of medical stockings significantly reduces the amount of recurrent ulcers. Furthermore, the relapse rate of venous leg ulcers can be significantly reduced by a combination of compression therapy and surgery of varicose veins compared with compression therapy alone.

    We aimed to present our clinical experience with FG treatment. Fournier's gangrene (FG) is a rare but serious disease characterized by progressive necrosis in the genitourinary and perineal region. The retrospective study included 43 patients. Patients were divided into 2 groups as survivors and nonsurvivors. Included in the analysis were data pertaining to demographics, predisposing factors, comorbidities, results of bacteriologic analyses, number of debridements, duration of treatment, FG Severity Index (FGSI) score, fecal diversion methods (trephine ostomy or Flexi-Seal Fecal Management System-FMS), and dressing methods (wet or negative aspiration system). In the nonsurvivor group, urea, WBC, and age were significantly higher, whereas albumin, hematocrit, platelet count, and length of hospital stay (LOHS) were significantly lower compared to the survivor group. Mean FGSI was lower in survivors in comparison with nonsurvivors (5.00 ± 1.86 and 10.00 ± 1.27, respectively; P < 0.001). We conclude that FGSI is an important predictor in the prognosis of FG. Vacuum-assisted closure (VAC) should be performed in compliant patients in order to enhance patient comfort by reducing pain and the number of dressings. Fecal diversion should be performed as needed, preferably by using FMS. The trephine ostomy should be the method of choice in cases where an ostomy is necessary. PMID:25859652

    PubMed

    2000-01-01

    Cancrum oris (Noma) is a devastating infectious disease which destroys the soft and hard tissues of the oral and para-oral structures. The dehumanizing oro-facial gangrenous lesion affects predominantly children ages 2 to 16 years, particularly in sub-Saharan Africa, where the estimated frequency in some communities varies from 1 to 7 cases per 1000 population. The risk factors are poverty, malnutrition, poor oral hygiene, residential proximity to livestock in unsanitary environments, and infectious diseases, particularly measles and those due to the herpesviridae. Infections and malnutrition impair the immune system, and this is the common denominator for the occurrence of noma. Acute necrotizing gingivitis (ANG) and oral herpetic ulcers are considered the antecedent lesions, and ongoing studies suggest that the rapid progression of these precursor lesions to noma requires infection by a consortium of micro-organisms, with Fusobacterium necrophorum (Fn) and Prevotella intermedia (Pi) as the suspected key players. Additional to production of a growth-stimulating factor for Pi, Fn displays a classic endotoxin, a dermonecrotic toxin, a cytoplasmic toxin, and a hemolysin. Without appropriate treatment, the mortality rate from noma is 70-90%. Survivors suffer the two-fold afflictions of oro-facial mutilation and functional impairment, which require a time-consuming, financially prohibitive surgical reconstruction. PMID:12002813

  12. Fournier gangrene presenting in a patient with undiagnosed rectal adenocarcinoma: a case report

    PubMed Central

    2009-01-01

    Introduction Fournier gangrene is a rare necrotising fascitis of the perineum and genitals caused by a mixture of aerobic and anaerobic microorganisms. The first case was described by Baurienne in 1764 but the condition was named by Fournier in 1883 who reported the cases of five men with the condition with no apparent etiology. Infection most commonly arises from the skin, urethra, or rectal regions. Despite appropriate therapy, mortality in this disease is still high. We report a case of a low rectal malignancy presenting as Fournier gangrene. This case report serves to highlight an extremely unusual presentation of rectal cancer, a common surgical pathology. Case presentation The patient is a 48 years old Afghanian male that admitted with Fournier gangrene. In the course of medical and surgical treatment the presence of extensive rectal adenocarcinoma was discovered. After partial recovery, standard loop colostomy was inserted. Skin grafting of necrotic areas was performed and systemic rectal cancer chemotherapy initiated after full stabilization. Conclusion Fournier gangrene is an uncommon but life threatening condition with high associated mortality and morbidity. Usually there is an underlying cause for the development of Fournier gangrene, that if addressed correctly, can lead to a good outcome. Early diagnosis and treatment decrease the morbidity and mortality of this life threatening condition. Good management is based on aggressive debridement, broad spectrum antibiotics and intensive supportive care. PMID:20062653

    Temporary lingual and labial paraesthesia are not uncommon following the removal of mandibular third molar teeth. In patients with insulin-treated diabetes circum-oral paraesthesia is a common and important sign of impending hypoglycaemia. This report highlights the case of a 17-year-old girl with Type 1 (insulin-dependent) diabetes who, following the extraction of her four wisdom teeth, experienced minor circum-oral sensory disturbances. These effectively masked her early warning signs of impending hypoglycaemia which had hitherto allowed her to have very good glycaemic control. Trembling, sweating and loss of concentration became the new presenting symptom complex, which she found both disabling and worrying. Fortunately, within six months the paraesthesia had subsided and the patient was once again able to appreciate her usual warning symptom of impending hypoglycaemia. PMID:9718802

    Chronic venous insufficiency (CVI) is an important and frequent disease for dermatologists, phlebologists and general practitioners. There are various hypotheses for the ethiopathology in CVI, e. g. hormone receptors and impairments concerning the venous contraction or relaxation of the vessel wall and the venous valves might play an important role. At the moment, colour doppler-duplex sonography seems to be the diagnostic method of choice. Modern therapeutic options include compression systems alone or in combination with topical or systemic treatment including minimal invasive methods like endovenous laser or radiofrequency obliteration or foam sclerotherapy.

    Background Squamous cell carcinoma of the scrotum is rare and its development in the scar of Fournier's gangrene is still rarer. Case presentation A 65-year-old gentleman presented with a small non-healing ulcer developing on right hemi-scrotum two years after the treatment for Fournier's gangrene. On histological examination it was found to be squamous cell carcinoma. He was successfully managed by surgery in the form of wide local excision and ilio-inguinal lymph node dissection followed by adjuvant radiotherapy and chemotherapy. Conclusions Squamous cell carcinoma can develop in the scar of Fournier's gangrene after a long delay, which differentiates it from other scar carcinomas or Marjolin's ulcer. PMID:15113443

    Abstract Fournier gangrene is a necrotizing soft tissue infection involving the perineum. We present a case of Fournier gangrene as the clinical presentation of perforated metastatic rectal cancer. The patient is a 78-year-old man in a nursing home who presented to our institution with necrosis and ischemia of the scrotum. After wide debridement of necrotic tissue and bilateral orchiectomy, computed tomography was carried out to investigate abnormal findings seen on his chest X-ray, which revealed multiple pulmonary metastases as well as a mass highly suspicious for a perforated rectal mass. Once stable, a diverting colostomy and biopsies of the rectal mass were performed, confirming the presence of a metastatic, poorly differentiated rectal adenocarcinoma. Albeit an unusual etiology of Fournier gangrene, this case highlights the rare but important causes of this deadly condition and teaches us to be cognizant of the variations in the presentation of colorectal cancer.

  17. Reconstruction of Defects After Fournier Gangrene: A Systematic Review

    PubMed Central

    Karian, Laurel S.; Lee, Edward S.

    2015-01-01

    Background: Reconstruction of scrotal defects after Fournier gangrene is often achieved with skin grafts or flaps, but there is no general consensus on the best method of reconstruction or how to approach the exposed testicle. We systematically reviewed the literature addressing methods of reconstruction of Fournier defects after debridement. Methods: PubMed and Cochrane databases were searched from 1950 to 2013. Inclusion criteria were reconstruction for Fournier defects, patients 18 to 90 years old, and reconstructive complication rates reported as whole numbers or percentages. Exclusion criteria were studies focused on methods of debridement or other phases of care rather than reconstruction, studies with fewer than 5 male patients with Fournier defects, literature reviews, and articles not in English. Results: The initial search yielded 982 studies, which was refined to 16 studies with a total pool of 425 patients. There were 25 (5.9%) patients with defects that healed by secondary intention, 44 (10.4%) with delayed primary closure, 36 (8.5%) with implantation of the testicle in a medial thigh pocket, 6 (1.4%) with loose wound approximation, 96 (22.6%) with skin grafts, 68 (16.0%) with scrotal advancement flaps, 128 (30.1%) with flaps, and 22 (5.2%) with flaps or skin grafts in combination with tissue adhesives. Four outcomes were evaluated: number of patients, defect size, method of reconstruction, and wound-healing complications. Conclusions: Most reconstructive techniques provide reliable coverage and protection of testicular function with an acceptable cosmetic result. There is no conclusive evidence to support flap coverage of exposed testes rather than skin graft. A reconstructive algorithm is proposed. Skin grafting or flap reconstruction is recommended for defects larger than 50% of the scrotum or extending beyond the scrotum, whereas scrotal advancement flap reconstruction or healing by secondary intention is best for defects confined to less than 50

    Venous thromboembolic disease contributes to morbidity and mortality in certain groups of hospitalized patients, particularly those who have undergone surgery. Although principles of treatment have changed relatively little during the past 20 years, significant advances have been made in the diagnosis of deep vein thrombosis (DVT). Venography, once the only reliable diagnostic technique, has been largely replaced by noninvasive tests: impedance plethysmography, venous Doppler, /sup 125/I-radiofibrinogen-uptake test, and phleborheography. Virchow's triad of stasis, vessel injury, and hypercoagulability remains a valid explanation of the pathogenesis of thrombus formation, but laboratory and clinical data have refined our knowledge of how these factors interact to result in clinically significant disease. Knowledge of the natural history of venous thrombosis, plus heightened awareness of the long-term morbidity and expense associated with the postphlebitic syndrome, have led to increased interest in preventing DVT. Clinically and economically, venous thrombosis is best managed by prevention. 61 references.

    Cryoglobulins are monoclonal or polyclonal immunoglobulins that undergo reversible precipitation at low temperatures. Cryoglobulinemia is associated with HCV infection in more than 90% cases, the remaining 10% being called as Essential Cryoglobulinemia which is generally associated with a severe course and suboptimal response to conventional therapies. As the digital vessels are more prone to colder temperatures, hyperviscosity in those vessels can initiate local thrombosis and may manifest as ischemic ulceration and gangrene. We report here a very unusual case of HCV negative cryoglobulinemic vasculitis presenting as symmetrical peripheral gangrene of fingers and toes. PMID:27190872

    Allroggen, H.; Abbott, R.

    2000-01-01

    Cerebral venous sinus thrombosis is a challenging condition because of its variability of clinical symptoms and signs. It is very often unrecognised at initial presentation. All age groups can be affected. Large sinuses such as the superior sagittal sinus are most frequently involved. Extensive collateral circulation within the cerebral venous system allows for a significant degree of compensation in the early stages of thrombus formation. Systemic inflammatory diseases and inherited as well as acquired coagulation disorders are frequent causes, although in up to 30% of cases no underlying cause can be identified. The oral contraceptive pill appears to be an important additional risk factor. The spectrum of clinical presentations ranges from headache with papilloedema to focal deficit, seizures and coma. Magnetic resonance imaging with venography is the investigation of choice; computed tomography alone will miss a significant number of cases. It has now been conclusively shown that intravenous heparin is the first-line treatment for cerebral venous sinus thrombosis because of its efficacy, safety and feasability. Local thrombolysis may be indicated in cases of deterioration, despite adequate heparinisation. This should be followed by oral anticoagulation for 3-6 months. The prognosis of cerebral venous sinus thrombosis is generally favourable. A high index of clinical suspicion is needed to diagnose this uncommon condition so that appropriate treatment can be initiated.

    PubMed

    2014-01-01

    The Infectious Disease Society of America has defined gas gangrene as an infection caused by Clostridium species. However, in many clinical settings, soft tissue infections that produce subcutaneous gas have been diagnosed as gas gangrene without identification of the presence of Clostridium species. Instead, the diagnosis was based on clinical and radiographic findings. A chart review was performed of 25 consecutive patients treated at the Atlantic Health System for infections of the lower extremity that were diagnosed as gas gangrene. Wound cultures from the 25 patients grew 31 different species of bacteria. The most prevalent organism was Staphylococcus aureus, which accounted for 17 of 31 (54.84%) different organisms identified and 19.77% of 86 separate aerobic or anaerobic cultures. The most prevalent genus was Streptococcus, which accounted for 20 (64.52%) of the organisms identified and 23.26% of the cultures. The most prevalent anaerobic genus was Peptostreptococcus, which accounted for 8 (25.81%) of the organisms identified and 9.3% of the cultures. None of the cultures grew Clostridium species. These findings showed that gas-forming soft tissue infections of the lower extremity, commonly diagnosed as gas gangrene, are rarely caused by Clostridium species. PMID:24345706

  16. Management of unusual genital lymphedema complication after Fournier’s gangrene: a case report

    PubMed Central

    2012-01-01

    Background Fournier’s gangrene is a bacterial infection characterized by necrotizing fasciitis, skin and soft tissue involvement, and eventually myositis of the perineal region. Aggressive debridement of devitalized tissue and overlying skin is of paramount importance, but often leaves large defects to be reconstructed. The present case reports successful extensive perineal defects coverage following Fournier’s gangrene and management of subsequent penile lymphoedema impairing sexual function in a young patient. Case presentation Following perianal abscess drainage, a healthy young man presented with scrotal pain. Fournier’s gangrene was diagnosed and treated with multiple surgical debridements. Tissue excision extended through the entire perineal area, base of the penile shaft, lower abdominal region, the inner thighs, and gluteal region, corresponding to 12% of the total body surface area. After serial debridements and negative pressure dressings, the defect was covered by two stages of skin grafting. Graft take was 90%. Healing was achieved without hypertrophic or retractile scar. However, chronic penile lymphedema remained and was first treated with compressive garments for 2 years. Upon failure of this conservative approach, we performed a circumcision, but only a “penile lift” allowed a satisfactory esthetical and functional result. Conclusion Fournier’s gangrene can be complicated by a chronic lymphedema of the penis. Conservative treatment is likely to fail in severe cases and can be treated surgically by “penile lift”.

    2015-03-01

    The evaluation of patients with venous ulceration primarily includes noninvasive methods to elucidate the distribution and extent of pathology. Duplex ultrasound is the first line of investigation, as it provides assessment of both reflux and obstruction conditions. In patients with iliofemoral pathology, axial imaging with computed tomography scan or magnetic resonance imaging should be performed. If the treatment of iliofemoral vein obstruction is warranted, then invasive assessment using venography and/or intravascular ultrasound should be used to guide the interventional procedure. Venous valve reflux can be identified and accurately characterized by duplex ultrasound, whereas the ultrasound assessment of functional abnormality associated with obstruction is less reliable. In patients with ulceration, the evaluation for and treatment of proximal venous obstruction has resulted in improved ulcer healing. PMID:26358305

In 1856, Dr Rudolf Virchow developed the concept outlining the genesis of intravascular thrombosis. Dr Virchow hypothesized that circulatory stasis due to interrupted blood flow, changes in the blood leading to blood coagulation, and irritation or damage to the vascular endothelium would initiate acute venous thrombus generation. Presently, it is known that these above-mentioned risk factors are influenced by increasing age, gender, and obesity. The current chapter will focus on recent preclinical and clinical investigations that will give the reader insight into the prothrombotic mechanisms that lead to acute venous thrombosis.

    A total of 50 does were used to determine selected hematological and biochemical parameters with special references to oxidative stress markers, acute phase protein profiles, and proinflammatory cytokines in healthy and gangrenous mastitis affected does. Animals were divided into two equal groups represented as clinically healthy (control) and diseased groups, respectively. The bacteriological examination of milk samples from diseased does revealed many types of bacterial infection. The isolated bacteria were Staphylococcus aureus (N=23/25), Escherichia coli (N=11/25), and Clostridium perfringens (N=4/25). There was a significant increase in the levels of β-hydroxybutyrate, non-esterified free fatty acids, triglyceride, low density lipoprotein cholesterol (LDL-C), aspartate aminotransferase, and alanine aminotransferase and a significant reduction in the levels of glucose, cholesterol, and high density lipoprotein cholesterol (HDL-C) in does with gangrenous mastitis compared to healthy does. Moreover, there was a significant increase in the levels of malondialdehyde and uric acid with a significant decrease in the levels of reduced glutathione, super oxide dismutase, and catalase in does with gangrenous mastitis compared to healthy does. In addition, there was a significant increase in the haptoglobin, serum amyloid A, fibrinogen, interleukin 6 (IL-6), IL-1β, and tumor necrosis factor-α (TNF-α) in does with gangrenous mastitis compared to healthy ones. Conclusively, oxidative stress biomarkers, acute phase proteins, and proinflammatory cytokines play an essential task as biomarkers for gangrenous mastitis in does. Mastitis may be considered as one of the ketotic stressors in does after parturition. PMID:23303629

    Women have a high incidence of chronic venous disease. Venous occlusive disease can lead to significant morbidity and even death. Factors such as genetics, medications, and diseases can play a role in the development of venous thrombosis. In women, pregnancy can lead to a hypercoagulable state and a greater risk of venous complication. Awareness and education will be very important in the future to help identify those patients at risk. PMID:23522718

    This article reviews published data on the effects of surgery and compression in the treatment of venous ulcers and the best options for compression therapy. Randomized controlled studies reveal that surgery and compression have similar effectiveness in healing ulcers but surgery is more effective in preventing recurrence. Most leg ulcers have a venous pathophysiology and occur because of venous ambulatory hypertension caused by venous reflux and impairment of the venous pumping function. Proposed surgical interventions range from crossectomy and stripping to perforator vein interruption and endovascular procedures (laser, radiofrequency). More conservative procedures (foam sclerotherapy, conservative hemodynamic treatment) have also been proposed. PMID:22732375

    Advanced medical treatment options have improved pediatric survival but often require invasive vascular procedures or venous access. These procedures increase the risk for thromboembolism in children, and there has been a corresponding increase in the reported incidence of deep venous thrombosis and postthrombotic syndrome in the pediatric population. Percutaneous venous interventions using catheter-directed therapy (CDT), like mechanical thrombectomy and infusion thrombolysis, have been used much less frequently in children, even though they have shown good results in adults. A multidisciplinary team including pediatric hematology, interventional radiology, and intensive care unit is suggested for management of venous thrombosis in children. Indications and contraindications for CDT in children are similar to adults. Mechanical thrombectomy and infusion thrombolysis are some of the more commonly performed treatments. CDT in children requires adapting to patient size and locally available equipment. Ultrasound guidance for access, "cork" technique, appropriate dosing of tissue plasminogen activator for infusion/pharmacomechanical thrombolysis, and simultaneous administration of heparin, plasminogen (fresh frozen plasma), and deficient coagulation factors are some of the important variations of CDT technique in children. Postprocedure monitoring is very important for successful thrombolysis. Retrievable inferior vena cava filters are increasingly being used in children as well, for prophylaxis against pulmonary embolism (PE) if there is a significant risk of PE with/without contraindications to anticoagulation.

    This study proposals a new method, short-impending anomaly of GPS (SIA-GPS), to predict the coming earthquake. Based on long-term GNSS observations, we observed the abnormal deformations occurred around the active faults in Yunnan area before the earthquakes of magnitude MW³5.0. We constructed the regional strain fields with networks filtering, and extracted the abnormal deformations of each grid before each strong coming earthquake. Such special deformations of the GNSS observation are able to serve for short-impending earthquake prediction. The SIA-GPS method includes three steps. Firstly, Yunnan region is divided into multiple grids using interpolation calculation and the uniform displacement field is created. The area velocity field is obtained based on the continuous GNSS observations using GAMIT/GLOBK software. Next, the earthquake response capacity of each grid is evaluated in time-series analysis focusing on strains, and the short-term anomalies are easily extracted. Lastly, all the abnormal signals are carefully diagnosed in the considerations of tectonic movements. As examples, we predicated 19 earthquakes using the (SIA-GPS) method. 14 earthquakes of them are successful within the tolerable special and time misfits, and 5 of them do not occurred. The code of predication for short-impending earthquake requires that all the coming earthquakes of Mw³5 must be predicated, the maximum time error for coming event is three months, and the corresponding spatial misfit allows 5 grids. Following this role, 14 earthquakes of Mw³5 are predicted using SIA-GPS indicators with success rate 73.6%. For such experiences, SIA-GPS method has been utilized as a benefit tool to predicate the potential coming earthquakes in Earthquake Administration of Yunnan Province.

    Chronic venous disease is a common condition with clinical signs and symptoms ranging from spider veins, to varicose veins, to active venous ulceration. Both superficial and deep venous dysfunction may be implicated in the development of this disease. Socio-economic factors are shaping our population, with increasing age and body mass index resulting in significant pressure on healthcare systems worldwide. These risk factors also lead to an increased risk of developing superficial and/or deep venous insufficiency, increasing disease prevalence and morbidity. In this chapter, the authors review the current and future burden of chronic venous disease from an epidemiological, quality of life and economic perspective. PMID:26916773

    An incurable cancer is a threat to life itself. This study focused on how native-born Swedes, who define themselves as nonreligious, actually reflect and act when they try to create helpful strategies in the presence of their own impending deaths and how the strategies serve their purposes. Twenty patients were interviewed in depth. The patients were enrolled in an advanced hospital-based home care team. The interviews were taped, transcribed and analyzed with a qualitative, hermeneutic interpretative method. The informants' efforts to develop useful strategies to restrain death could be symbolized as a cognitive and emotional pendulum, swinging between the extremes of life and death. During the swings of the pendulum, the informants used every means available: their own resources, other people, animals, nature, a transcendent power, hope, imagination and magical thinking. They strove to find factors that fitted their conceptual system and supported their inner balance and structure, all to keep death at a discreet distance and preserve their links to life. These links were togetherness, involvement, hope and continuance, and they served as a shield against hurtful feelings connected to their impending death. The new knowledge about how strategies in the presence of one's own impending death can develop and be used is perhaps the most novel and clinically relevant contribution of this study.

    Achieving an aesthetic appearance of the scrotum after extensive Fournier’s gangrene is a reconstructive challenge. Testicular coverage is often prioritized over scrotal cosmesis due to the comorbidities typically seen in this patient population. We describe our treatment of a young, healthy male with extensive Fournier’s gangrene, with loss of the scrotum. Bilateral neurotized anterolateral thigh flaps were used to achieve a sensate and aesthetically acceptable result. PMID:24554975

    Cellulitis of the scrotum and penis is caused, in the majority of instances, by a beta hemolytic streptococci without a discernible portal of entry. Clostridium, occasionally, will result in this disease as a manifestation of a perirectal abscess. In either instance, fluid accumulates rapidly in the closed space between Colles' and Buck's fascia, producing intense swelling of the scrotum. If this compartment is not immediately decompressed by linear incisions, devascularization of the scrotal and penile skin will often occur, resulting in gangrene. Immediate treatment of the bacterial infection with penicillin also is essential. If gangrene does develop, radical debridement of the necrotic tissue as well as a wide margin of adjacent inflamed skin must be undertaken. Continual monitoring of the microflora of the debrided would is essential for the selection of the appropriate antibiotic against any secondary intruders. Coverage of the granulating would is accomplished when the would bacterial count is below 10-5 per gram of tissue. PMID:1098183

    Intra-abdominal Hernias are rare conditions usually secondary to congenital defects, with pericecal hernias accounting for a minority of them. They can be difficult to diagnose due to non-specific presentations but may lead to strangulation and thus require early management. We herein report a rare case of pericecal hernia with gangrenous appendicitis in an 88 year-old lady presenting with features of acute intestinal obstruction and right iliac fossa lump, which on exploration was found to be a pericecal hernia with knotting, strangulation, and gangrenous changes of appendix. This case highlights the need of a high index of suspicion for internal hernias and that of prompt operative intervention to avoid enterectomies and to improve outcome. PMID:27162920

    Takayasu's arteritis (TA) is a granulomatous large vessel vasculitis more commonly seen in India. The vascular inflammation in TA results in stenoses of affected vessels. Usually this is a slow process with good collateral circulation; only rarely does critical limb ischemia result. We present two patients of TA who presented with gangrene of extremities, and review eight prior such patients reported in the literature. With appropriate diagnosis and treatment with oral corticosteroids and low-dose aspirin, none of our patients had recurrence at a mean follow-up of 3.8 ± 2.8 years. Although rare, TA can present with gangrene and rheumatologists need to be aware of this unusual but limb-threatening manifestation of TA to institute appropriate therapy in a timely manner.

    Despite being one of the main pathogens involved in ruminant mastitis, little is known about what proteins Staphylococcus aureus does express, in vivo, during the infection. Here, two S. aureus strains were isolated from curds formed within the udder of two ewes suffering from gangrenous mastitis. Protein samples were prepared from cell fractions and were analyzed using 1D-LC MS/MS. Results were compared to 1D-LC MS/MS analysis of the same S. aureus strains grown in ewe milk. A total of 365 proteins were identified. Most of them were related to cellular metabolism, cellular division and stress response. Half of the proteins were found in both conditions but a substantial number were specifically found in in vivo conditions and gave indications about the active metabolic status and the stresses encountered by S. aureus within the cistern during a gangrenous mastitis.

    Fournier gangrene (FG) is an infectious condition with fulminant evolution and is sometimes life-threatening. Here, we present the case of an immunocompromised 59-year-old male with surgical history of a pancreatic pseudocyst stented endoscopically. After unrecognized stent migration in the sigmoid without colonic perforation, he developed severe necrosis of the scrotum and perineum, which spontaneously perforated, presenting a smell suggesting moist gangrene. FG that has spread to the male genital organs presents therapeutic challenges. The purpose of our study is to present this case, typical for FG, with an educational aim both for the internal and surgical specialties, and the goal of further multidisciplinary collaboration for the optimal management of the patient with personalized treatment.

    2015-01-01

    Thrombosis can affect any venous circulation. Venous thromboembolism (VTE) includes deep-vein thrombosis of the leg or pelvis, and its complication, pulmonary embolism. VTE is a fairly common disease, particularly in older age, and is associated with reduced survival, substantial health-care costs, and a high rate of recurrence. VTE is a complex (multifactorial) disease, involving interactions between acquired or inherited predispositions to thrombosis and various risk factors. Major risk factors for incident VTE include hospitalization for surgery or acute illness, active cancer, neurological disease with leg paresis, nursing-home confinement, trauma or fracture, superficial vein thrombosis, and—in women—pregnancy and puerperium, oral contraception, and hormone therapy. Although independent risk factors for incident VTE and predictors of VTE recurrence have been identified, and effective primary and secondary prophylaxis is available, the occurrence of VTE seems to be fairly constant, or even increasing.

    Chronic venous insufficiency of the lower limbs is very prevalent. In recent decades, Doppler ultrasound has become the method of choice to study this condition, and it is considered essential when surgery is indicated. This article aims to establish a method for the examination, including venous mapping and preoperative marking. To this end, we review the venous anatomy of the lower limbs and the pathophysiology of chronic venous insufficiency and explain the basic hemodynamic concepts and the terminology required to elaborate a radiological report that will enable appropriate treatment planning and communication with other specialists. We briefly explain the CHIVA (the acronym for the French term "cure conservatrice et hémodynamique de l'insuffisance veineuse en ambulatoire"=conservative hemodynamic treatment for chronic venous insufficiency) strategy, a minimally invasive surgical strategy that aims to restore correct venous hemodynamics without resecting the saphenous vein.

    Introduction: Fournier’s gangrene is a rapidly progressing necrotizing fasciitis of the perineum and genital area associated with a high mortality rate. We presented our experience in managing this entity and identified prognostic factors affecting mortality. Methods: We carried out a retrospective study of 72 patients treated for Fournier’s gangrene at our institution between January 2005 and December 2014. Patients were divided into survivors and non-survivors and potential prognostic factors were analyzed. Results: Of the 72 patients, 64 were males (89%) and 8 females (11%), with a mean age of 51 years. The most common predisposing factor was diabetes mellitus (38%). The mortality rate was 17% (12 patients died). Statistically significant differences were not found in age, gender, and predisposing factors, except in heart disease (p = 0.038). Individual laboratory parameters significantly correlating with mortality included hemoglobin (p = 0.023), hematocrit (p = 0.019), serum urea (p = 0.009), creatinine (p = 0.042), and potassium (p = 0.026). Severe sepsis on admission and the extent of affected surface area also predicted higher mortality. Others factors, such as duration of symptoms before admission, number of surgical debridement, diverting colostomy and length of hospital stay, did not show significant differences. The median Fournier’s Gangrene Severity Index (FGSI) was significantly higher in non-survivors (p = 0.002). Conclusion: Fournier’s gangrene is a severe surgical emergency requiring early diagnosis and aggressive therapy. Identification of prognostic factors is essential to establish an optimal treatment and to improve outcome. The FGSI is a simple and valid method for predicting disease severity and patient survival.

    Objective: To report our experience with Fournier’s Gangrene (FG) over the past eight years and evaluate the predisposing factors which affect the mortality. Methods: Sixty-five patients who were admitted to emergency surgical unit of our institution presenting with FG between January 2006 and August 2014 were included. The anatomical site of infective gangrene, predisposing factors, etiological factors, and outcomes were retrospectively reviewed. Results: Our cases included 8 women and 57 men. The average age of men was 51±13.9 (range 19-75) and the average age of women was 63±10.5 (range 52-76). Average hospitalization time was 9.2±6.6 days (range 5-25) days. The most frequent comorbid disease was diabetes mellitus and the most frequent etiology was perianal abscess. Colostomy was performed in 11 patients, orchidectomy in two patients, cystostomy in two patients. Notably, all of the 8 (12.3%) patients who died from FG had diabetes and low socioeconomic status. A total of six patients who died required more than one surgical debridement. Conclusions: Fournier’s gangrene is a severe surgical emergency, with a high mortality rate. Low socioeconomic status, diabetes and more than one debridement play a major role in mortality and morbidity. PMID:27375726

    Gas gangrene develops in devitalized hypoxic tissue. It spreads rapidly under strong influence of enzymes produced by the causing bacteria and often results in fatal outcome. It is of utmost importance to stop toxin production as soon as possible, which is most effectively achieved by early application of hyperbaric oxygenation (HBO2), as the first measure in a "trident" (HBO2, antibiotics, surgical measures). The paper reviews the most important data from microbiology, pathophysiology and epidemiology of gas gangrene, current clinical practice, scientific basis for application of HBO2 in the treatment of this disease, and data from the archives of the Naval Medical Institute of the Croatian Navy in Split (NMI). At the NMI, in the period from 1982 to 2000, HBO2 was administered in the treatment of 21 patients with gas gangrene, of average age 41.6 +/- 16.3 years. The average treatment consisted of 6.8 +/- 3.8 sessions. 13 (76%) patients were cured. PMID:12152414

    Bochdalek hernia is the most frequent congenital diaphragmatic hernia which occurs due to a defect in the posterior attachment of the diaphragm when there is a failure of closure of the pleuroperitoneal membrane in utero. It rarely presents for the first time in adults. We report one such case of a 23-year-old male patient who presented with an acute abdomen. Chest X-ray showed air under diaphragm and he was taken up for an emergency laparotomy. Intraoperatively an organoaxial volvulus of the stomach was found in a bochdaleks hernia with a focal gangrene of the stomach fundus with perforation and peritonitis. However, there was no breach of pleural cavity. A sleeve resection of the gangrenous portion of the stomach was performed and the diaphragmatic defect was repaired. Patient made an uneventful postoperative recovery. Gastric gangrene with perforation as a manifestation of the adult bochdalek hernia is indeed rare. A concomitant pneumothorax occurs along with this condition which requires an intercostal drainage tube prior to the laparotomy. We report this case for its unique presentation without pneumothorax.

    In some patients of Fournier gangrene originated from perianal region, it is important to prevent fecal contamination in order to provide healing without wound infection. For this purposes, diverting colostomy or bowel management catheter methods were performed. In this study, it is aimed to carry out a comparison of prognosis and cost efficiency between diverting colostomy and bowel management catheter methods applied for preventing fecal contamination in Fournier's gangrene patients. Fourty-eight patients with diagnosis of Fournier's gangrene, serious perianal infections, and preserved sphincters and without rectum injury after debridement were included in the study. The cases were divided into two groups as patients who were subjected to colostomy for fecal diversion and who were subjected to bowel management catheter without colostomy. Then, the groups were compared in terms of age, predisposing factors, duration of hospital stay, mortality, additional surgery requirements, and cost. Fourty-eight patients were included the study. Sixteen patients were treated without colostomy. Decreased duration of total hospital stay, additional surgery requirements, and hospital expense in bowel management catheter group has determined. It is thought that preferring bowel management catheter method instead of colostomy in patients without rectum injury, who require diverting colostomy and have undamaged anal sphincters, can relieve patients, patients' relatives, healthcare organizations, and the national economy of a serious burden. In addition, although patients' satisfaction and workforce loss factors are not taken into consideration in this study, the bowel management catheter method is thought to have positive effects also on these parameters.

    INTRODUCTION Acute ischemia of the rectum resulting in full thickness necrosis is extremely uncommon because of its excellent blood supply. PRESENTATION OF CASE We present 3 cases with spontaneous ischemic gangrene of the rectum. All three patients were elderly with atherosclerotic arterial disease and presented with hypotensive shock but in none of these patients we encountered a precipitating factor such as preceding vascular surgery or shock state. DISCUSSION A high index of suspicion should be maintained in elderly patients with atherosclerotic disease who present with lower GI symptoms with hypotensive shock and an inflamed rectum on CT scan. Immediate beside proctoscopy should be offered to these patients and if the diagnosis is confirmed these patients should be taken to the operating room immediately. If the entire rectum is found to be gangrenous then an emergency APR should be performed and the perineal wound left open. If the rectum is partially gangrenous then a low anterior resection with Hartman's procedure for diversion is appropriate. CONCLUSION Prompt diagnosis and resuscitation followed by immediate surgical intervention is necessary to save these elderly patients. PMID:24240084

    Introduction: Fournier’s gangrene is an infective necrotizing fasciitis of external genital and perineal region. Hematologic malignancies and immunocompromised status are predisposing factors. Simultaneous occurrence of Fournier’s gangrene and congenital leukemia in neonates is extremely rare. Case Presentation: We present a case of Fournier’s gangrene in a 4-day-old female infant with a necrotic lesion in perineum and no history of trauma or other predisposing condition. Focusing on high blast percentage in blood cell count she was affected by acute myeloid leukemia (M4 type). Pseudomonas aeruginosa was isolated from the blood and wound culture. She was treated with broad spectrum antibiotics and supportive care. The parents refused chemotherapy and the patient was discharged from hospital. Bleeding and DIC was the cause of death in a local hospital few days later. Conclusions: High index of suspicion is essential for diagnosis and appropriate treatment. Congenital leukemia should be considered in the differential diagnosis of a newborn with clinical features of sepsis and necrotizing fasciitis.

    Introduction Acute cholecystitis is a common surgical condition, but not many are aware of the serious complication of gangrenous cholecystitis (GC). Presence of GC increases patients’ postoperative complications, morbidity and mortality. Predictive factors for GC include age >45, male gender, white blood cell count >13,000/mm3 and ultrasound findings of a negative Murphy’s sign. Case presentation (1) GW, 83 male with dull right upper quadrant pain and a negative Murphy’s sign with further imaging showing a thickened septated gallbladder suggestive of GC. Patient’s surgery was difficult and he received a cholecystostomy tube for drainage. (2) PH, 75 male with minimal right upper quadrant pain, equivocal ultrasound with a negative Murphy’s sign and computer tomography (CT) showing acute cholecystitis. Patient was taken to the operating room for cholecystectomy, with pathology consistent with gangrenous cholecystitis. Discussion Multiple laboratory findings and imaging patterns have been found to be highly predictive of GC. Along with age and WBC, thickened gallbladder wall and lack of mucosal enhancement have been predictive of GC. On physical examination, lack of Murphy’s sign secondary to denervation from gangrenous changes also increases the index of suspicion for GC. Conclusion GC is a serious complication of acute cholecystitis with increased morbidity and mortality. There should be a high index of suspicion for GC if the above unique physical and laboratory findings are present. PMID:25917175

    A study was carried out on the properties and significance of staphylococci isolated from the alveoli after dental extraction (12 strains), from parodontal pus (19 strains) and pulpar gangrene (15 strains). By their frequency, staphylococci of the Staphylococcus aureus have an etiologic significance in pulpar gangrene. Of particular importance for the diagnosis and epidemiology was the predominance of lysotype 80 among the staphylococci isolated from pulpar gangrene and lysotype 77 in healthy carriers. In 2 of 11 patients the coexistence of the same lysotype was found in the pulpar gangrene and nasal secretion. PMID:379963

    2011-01-01

    Introduction Leg ulcers usually occur secondary to venous reflux or obstruction, but 20% of people with leg ulcers have arterial disease, with or without venous disorders. Between 1.5 and 3.0/1000 people have active leg ulcers. Prevalence increases with age to about 20/1000 in people aged over 80 years. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of standard treatments, adjuvant treatments, and organisational interventions for venous leg ulcers? What are the effects of advice about self-help interventions in people receiving usual care for venous leg ulcers? What are the effects of interventions to prevent recurrence of venous leg ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2011 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 101 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: compression bandages and stockings, cultured allogenic (single or bilayer) skin replacement, debriding agents, dressings (cellulose, collagen, film, foam, hyaluronic acid-derived, semi-occlusive alginate), hydrocolloid (occlusive) dressings in the presence of compression, intermittent pneumatic compression, intravenous prostaglandin E1, larval therapy, laser treatment (low-level), leg ulcer clinics, multilayer elastic system, multilayer elastomeric (or non-elastomeric) high-compression regimens or bandages, oral treatments (aspirin, flavonoids

    Objective: Fournier’s gangrene is a progressive, necrotizing fasciitis due to synergistic infection of the perineum and external genitalia that is associated with high mortality and morbidity. The purpose of this study is to review the diagnostic and treatment methods that effect mortality in Fournier’s gangrene. Material and Methods: Sixteen patients who were diagnosed and treated at our clinic between 2011 and 2013 due to Fournier’s gangrene were retrospectively analyzed. The surviving and non-surviving patient groups were compared in terms of age, sex, onset time of symptoms, isolated microorganisms, concomitant diseases, Fournier’s gangrene severity index (FGSI), and length of hospital stay. Results: Ten of our cases (62.5%) were male and six (37.5%) were female, with a mean age of 61.2±12.3 (42–73) years. The mortality rate was 18.8% (3 cases). The mean duration of symptoms before admission was 4.31±1.81 (2–8) days. This period was 6.67±1.52 days in patients who succumbed to death, and 3.77±1.42 days in patients who survived (p=0.007). Ten cases (62.5%) had concomitant diabetes mellitus. The most common organism isolated in wound cultures was Escherichia coli (68.7%), and Acinetobacter baumannii, Proteus mirabilis, methicillin-resistant Staphylococcus aureus and Enterococcus spp. in the remaining patients. The mean FGSI of surviving patients was 3.84±1.77, and 7.66±0.57 in fatal cases (p=0.003). The mean length of hospital stay was 25.5 days (2–57) and duration of hospitalization was significantly longer in survivors (p<0.05). Conclusion: The delay in diagnosis and higher FGSI may be responsible for worsening of prognosis and mortality in Fournier’s gangrene. Early diagnosis and determination of the severity of the disease, aggressive surgical debridement and appropriate antimicrobial therapy may improve prognosis. PMID:25931901

    Venous disease is the most common cause of chronic leg ulceration and represents an advanced clinical manifestation of venous insufficiency. Due to their frequency and chronicity, venous ulcers have a high socioeconomic impact, with treatment costs accounting for 1% of the health care budget in Western countries. The evaluation of patients with venous ulcers should include a thorough medical history for prior deep venous thrombosis, assessment for an hypercoagulable state, and a physical examination. Use of the CEAP (clinical, etiology, anatomy, pathophysiology) Classification System and the revised Venous Clinical Severity Scoring System is strongly recommended to characterize disease severity and assess response to treatment. This venous condition requires lifestyle modification, with affected individuals performing daily intervals of leg elevation to control edema; use of elastic compression garments; and moderate physical activity, such as walking wearing below-knee elastic stockings. Meticulous skin care, treatment of dermatitis, and prompt treatment of cellulitis are important aspects of medical management. The pharmacology of chronic venous insufficiency and venous ulcers include essentially two medications: pentoxifylline and phlebotropic agents. The micronized purified flavonoid fraction is an effective adjunct to compression therapy in patients with large, chronic ulceration. PMID:26358306

    It has been estimated that chronic venous insufficiency affects 10 to 35 percent of the entire U.S. population and that 4 percent of people older than 65 have active venous ulcers. The high prevalence of the disease results in an annual expenditure of more than 1 billion dollars a year to the U.S. health care system. To have a rational approach toward patients with venous ulcers, it is important to understand the pathophysiology and clinical characteristics of the disease process, in order to initiate appropriate treatment and prevent venous ulcer recurrence.

    Chronic venous insufficiency (CVI) results from venous hypertension secondary to superficial or deep venous valvular reflux. Treatment modalities are aimed at reducing venous valvular reflux, thereby inhibiting the ensuing pathologic inflammatory process. Compression therapy using pumps, bandaging, and/or graded compression stockings is the mainstay of treatment for CVI. Compression therapy has been shown to be effective in reducing venous hypertension retarding the development of inflammation and pathologic skin changes. Pharmacologic agents such as diuretics and topical steroid creams reduce swelling and pain short term but offer no long-term treatment advantage. Herbal supplements may reduce the inflammatory response to venous hypertension, but are not licensed by the US Food and Drug Administration, and vary in their efficacy, quality, and safety. However, several randomized controlled trials using the herbal horse chestnut seed extract containing aescin have shown short-term improvement in signs and symptoms of CVI. Endovascular and surgical techniques aimed at treatment of primary and secondary venous valvular reflux have been shown to improve venous hemodynamics promoting healing of venous ulcers and improving quality of life. The newer endovascular treatments of varicose veins using laser, radiofrequency ablation, and chemical foam sclerotherapy show some promise. PMID:17484814

  12. Travel and venous thrombosis.

    2002-09-01

    Debate continues about whether and to what extent travel predisposes to venous thrombosis and pulmonary embolism (PE). Almost certainly, the strength of any association was greatly exaggerated in recent press reports. Conclusions from case-control studies vary, with some finding no excess of recent travel among patients with venous thromboembolism and others reporting a two-four fold excess. The strongest evidence that prolonged air travel predisposes to thrombosis comes from the travel history of people who present with PE immediately after landing. Two independent analyses suggest that the risk of early embolism increases exponentially with travel times beyond 6 hours and may reach 1:200,000 passengers traveling for more than 12 hours. The most likely explanation is venous stasis in the legs from prolonged sitting, and there is evidence (preliminary and controversial) that elastic support stockings may prevent deep vein thrombosis in people who travel long-distances. There is an urgent need for more and better studies to define the absolute hazard from travel-related thrombosis and the personal risk factors that may contribute. Without these, it is difficult to give a balanced account to people who intend to travel or to consider definitive prevention trials. Case reports suggest that in most cases, travel-related thrombosis has affected people who were also at risk because of previous thrombosis, recent injury, or other predispositions. This makes it sensible to target such "at risk" people with advice about hazards and precautions, at least until formal study validates some other approach. PMID:12172438

    We present a unique case of frosted branch angiitis in one eye and impending central retinal vein occlusion in other eye of a pregnant woman, which could be an initial manifestation of Behçet's disease. A 28-year-old, 33 weeks pregnant woman presented with sudden diminution of vision in her right eye. Her best-corrected visual acuity was light perception in the right eye and 20/20 in her left eye. The fundus examination revealed frosted branch angiitis in the right eye and impending central retinal vein occlusion in the left eye. After a thorough initial examination, she was administered intravenous methyl prednisolone 1 g once a day for 3 days followed by oral steroids. All extensive work up to find the cause of frosted branch angiitis was negative except for positive human leukocyte antigen B51. Systemic work up was normal. On last follow-up at 6 months, the patient had visual acuity of 20/60 in the right eye and 20/20 in the left eye. Her systemic work up was normal up to follow-up. She still remains a diagnostic dilemma, with Behçet's disease as the closest diagnosis. PMID:26055592

    Most left ventricular true aneurysms that occur secondary to blunt trauma gradually become symptomatic as they enlarge, which validates conservative management as a reasonable initial course of action. We report a case of impending rupture of a left ventricular true aneurysm that showed rapid expansion within a few weeks. A 17-year-old youth was involved in a head-on collision into a car while riding a motorcycle. He underwent repair of a ruptured jejunum and internal fixation of a fractured femur; 28 days after the accident, he was transferred to another hospital for rehabilitation. His chest X-ray just before the transfer was normal. He was re-admitted to our hospital 58 days after the accident complaining of anterior chest pain and dyspnea. Echocardiography showed impending rupture of a left ventricular aneurysm. We performed emergency open repair of a left ventricular true aneurysm with a very thin wall. We report this case to show that even a true aneurysm of the left ventricle should be carefully monitored from the early stage, considering the possibility of rupture. PMID:17952528

    Ecological regime shifts are large, abrupt, long-lasting changes in ecosystems that often have considerable impacts on human economies and societies. Avoiding unintentional regime shifts is widely regarded as desirable, but prediction of ecological regime shifts is notoriously difficult. Recent research indicates that changes in ecological time series (e.g., increased variability and autocorrelation) could potentially serve as early warning indicators of impending shifts. A critical question, however, is whether such indicators provide sufficient warning to adapt management to avert regime shifts. We examine this question using a fisheries model, with regime shifts driven by angling (amenable to rapid reduction) or shoreline development (only gradual restoration is possible). The model represents key features of a broad class of ecological regime shifts. We find that if drivers can only be manipulated gradually management action is needed substantially before a regime shift to avert it; if drivers can be rapidly altered aversive action may be delayed until a shift is underway. Large increases in the indicators only occur once a regime shift is initiated, often too late for management to avert a shift. To improve usefulness in averting regime shifts, we suggest that research focus on defining critical indicator levels rather than detecting change in the indicators. Ideally, critical indicator levels should be related to switches in ecosystem attractors; we present a new spectral density ratio indicator to this end. Averting ecological regime shifts is also dependent on developing policy processes that enable society to respond more rapidly to information about impending regime shifts. PMID:19124774

  16. The relationship between oxygen extraction and venous pH in sepsis.

    1997-11-01

    This study was performed to quantify the impact of Haldane effect (HE) on the relationship between O2 extraction (O2Ex; mL O2/dL blood) and venous pH in 247 measurements performed in 91 septic patients (73 patients with intra-abdominal sepsis, 11 with retroperitoneal abscesses, 6 with severe cholangitis, and 1 with gangrenous fasclitis). The severity of sepsis varied from relatively compensated to extremely diseased conditions. This allowed a detailed assessment of the impact of HE over a wide range of cardiorespiratory and metabolic abnormalities. A recently developed model was used to quantify blood CO2 exchange and Haldane relationships and, in particular, the buffering of venous pH allowed by O2Ex (O2-linked H+ binding) on the basis of arterial and mixed venous blood gas measurements. Arterio-venous pH difference (a-vDpH) was .033 +/- .024 (mean +/- SD). It increased with venoarterial CO2 concentration difference (v-aDCO2; mL CO2/dL blood), but the increase was moderated by a simultaneous increase in O2Ex, as the likely consequence of HE: a-vDpH = .006 + .017 (v-aDCO2) - .009 (O2Ex) [r2 = .96, p < < .001]. To confirm this, the moderation of a-vDpH allowed by the HE (DpH) was calculated. A first component, due to O2-linked H+ binding, had a value of .016 +/- .012, and a second component, due to the Haldane-mediated reduction in venous CO2 tension and plasma carbonic acid concentration, had a value of .019 +/- .006. Their sum (total DpH) was .033 +/- .017 and was related directly and strongly to O2Ex: DpH = -.002 + .009 (O2Ex) [r2 = .85, p < < .001], thus confirming the quantitative impact of HE in moderating the decrease in venous pH relative to arterial pH. The loss of this effect was responsible for the larger decreases in venous pH observed in hypodynamic patients developing impaired O2Ex. These results allow an easy quantification of the Haldane component, separated from the other components affecting pH, and are also useful for assessing the protective role

    Objective The importance of traumatic dural venous sinus injury lies in the probability of massive blood loss at the time of trauma or emergency operation resulting in a high mortality rate during the perioperative period. We considered the appropriate methods of treatment that are most essential in the overall management of traumatic dural venous sinus injuries. Methods We conducted a retrospective review of all cases involving patients with dural venous sinus injury who presented to our hospital between January 1999 and December 2014. Results Between January 1999 and December 2014, 20 patients with a dural venous sinus injury out of the 1,200 patients with severe head injuries who had been operated upon in our clinic were reviewed retrospectively. There were 17 male and 3 female patients. In 11 out of the 13 patients with a linear skull fracture crossing the dural venous sinus, massive blood loss from the injured sinus wall could be controlled by simple digital pressure using Gelfoam. All 5 patients with a linear skull fracture parallel to the sinus over the venous sinus developed massive sinus bleeding that could not be controlled by simple digital pressure. Conclusion When there is a linear skull fracture parallel to the sinus over the dural venous sinus or a depressed skull fracture penetrating the sinus, the surgeon should be prepared for the possibility of potentially fatal venous sinus injury, even in the absence of a hematoma.

    Cerebral sinus venous thrombosis (CSVT) is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT) and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment. PMID:24347950

    Here, we report a case of pyoderma gangrenosum of the penis which was difficult to distinguish from Fournier gangrene. The patient was a 54-year-old male who was aware of redness and swelling of the glanspenis for 1 month prior to a consultation at our department. Although he was diagnosed with herpes and treated at a nearby hospital, his symptoms did not improve. Subsequently, the patient visited our department following the onset of pain and fever. During his initial consultation, he had a fever of 39 °C as well as redness and swelling of the glans penis with partial spontaneous purulent discharge. His blood test revealed an elevated white blood cell count (20, 000/μl) and C-reactive protein (19.1 mg/dl). Because Fournier gangrene was suspected, administration of broad-spectrum antimicrobial agents was initiated but proved to be ineffective. An abscess (2 cm in diameter) was also noted in the umbilical region.Enterococcus faecalis was detected by the bacterial culture ; and therefore, Fournier gangrene was diagnosed. A partial penectomy was performed to control the infection. Pathological findings showed only non-specific inflammation ; however, fever persisted postoperatively and blood test results showed no improvement. Furthermore, new abscess lesions emerged on the right heel and back. Because the re-performed abscess bacterial culture test result was negative, pyoderma gangrenosum was suspected, and he was started on oral prednisolone (20 mg/day). On the following day, his fever subsided and his blood test results also showed improvement. A final diagnosis of pyoderma gangrenosum was ultimately made. PMID:26699892

    Traumatic gas gangrene is a fatal infection mainly caused by Clostridium perfringens. It is a challenge to manage gas gangrene in open wounds and control infection after debridement or amputation. The aim of the present study was to use vacuum sealing drainage (VSD) with continuous irrigation of potassium permanganate to manage infective wounds of gas gangrene and observe its clinical efficacy. A total of 48 patients with open traumatic gas gangrene infection were included in this study. Amputations were done for 27 patients, and limb salvage procedures were performed for the others. After amputation or aggressive debridement, the VSD system, including polyvinyl alcohol (PVA) foam dressing and polyurethane (PU) film, with continuous irrigation of 1:5000 potassium permanganate solutions, was applied to the wounds. During the follow-up, all the patients healed without recurrence within 8-18 months. There were four complications. Cardiac arrest during amputation surgery occurred in one patient who suffered from severe septic shock. Emergent resuscitation was performed and the patient returned to stable condition. One patient suffered from mixed infection of Staphylococcal aureus, and a second-stage debridement was performed. One patient suffered from severe pain of the limb after the debridement. Exploratory operation was done and the possible reason was trauma of a local peripheral nerve. Three cases of crush syndrome had dialysis treatment for concomitant renal failure. In conclusion, VSD can convert open wound to closed wound, and evacuate necrotic tissues. Furthermore, potassium permanganate solutions help eliminate anaerobic microenvironment and achieve good therapeutic effect on gas gangrene and mixed infection. VSD with continuous irrigation of potassium permanganate is a novel, simple and feasible alternative for severe traumatic open wounds with gas gangrene infection. PMID:26223928

  4. Death talk: gender differences in talking about one’s own impending death

    PubMed Central

    2014-01-01

    Background According to common practice based on a generally agreed interpretation of Icelandic law on the rights of patients, health care professionals cannot discuss prognosis and treatment with a patient’s family without that patient’s consent. This limitation poses ethical problems, because research has shown that, in the absence of insight and communication regarding a patient’s impending death, patient’s significant others may subsequently experience long-term psychological distress. It is also reportedly important for most dying patients to know that health care personnel are comfortable with talking about death and dying. There is only very limited information concerning gender differences regarding death talk in terminal care patients. Methods This is a retrospective analysis of detailed prospective “field notes” from chaplain interviews of all patients aged 30–75 years receiving palliative care and/or with DNR (do not resuscitate) written on their charts who requested an interview with a hospital chaplain during a period of 3 years. After all study patients had died, these notes were analyzed to assess the prevalence of patient-initiated discussions regarding their own impending death and whether non-provocative evocation-type interventions had facilitated such communication. Results During the 3-year study period, 195 interviews (114 men, 81 women) were conducted. According to the field notes, 80% of women and 30% of men initiated death talk within the planned 30-minute interviews. After evoking interventions, 59% (67/114) of men and 91% (74/81) of women engaged in death talk. Even with these interventions, at the end of the first interview gender differences were still statistically significant (p = 0.001). By the end of the second interview gender difference was less, but still statistically significant (p = 0.001). Conclusions Gender differences in terminal care communication may be radically reduced by using simple evocation

    Sleeve gastrectomy and gastric bypass surgery are popular and effective options for weight loss surgery. Portomesenteric vein thrombosis (PMVT) is a documented but rare complication of bariatric surgery. Proper surgical technique, careful postoperative prophylaxis, and early mobilization are essential to prevent this event. The diagnosis of PMVT in the postoperative period requires a high index of suspicion and early directed intervention to prevent a possibly fatal outcome. We present a case of PMVT complicated by small bowel ischemia resulting in gangrene that necessitated resection. PMID:26576312

    Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. Most often is asymptomatic but it may give a number of complications including gastrointestinal bleeding, obstruction and inflammation. Axial torsion and gangrene of MD are exceptional. The correct diagnosis of MD could only be made during surgery. Early surgery is important to reduce morbidity, especially perforation. Laparoscopy aided in the diagnosis and adequate treatment. We herein describe the case of a 4-year-old boy with axial torsion of MD. Clinical and radiographic finding suggest a segmental volvulus. Laparoscopy contributes to diagnosis and treatment of torted MD. PMID:27502885

    Fournier's gangrene is a type of necrotising fasciitis around the scrotum and perineum. Because of its aggressive nature, patients should be treated with broad-spectrum antibiotics and emergency, radical debridement during the acute phase. After recovering from the acute phase, reconstruction of the scrotal and perineal soft tissue defects is needed and is often challenging. Traditionally, various reconstruction methods have been used, including skin grafts, fasciocutaneous flaps and musculocutaneous flaps, each with its pros and cons. We successfully covered a wide scrotal defect using a superficial circumflex iliac artery perforator flap, which has not been previously reported for this indication.

    Of 33 patients with impending myocardial infarction 25 were treated using a combination of coronary artery by-pass grafting and intra-aortic balloon pumping. Eight patients were treated with coronary artery by-pass grafting alone. Twenty-two of the 25 patients who were treated with the combined technique made a full recovery. Three patients sustained definite myocardial infarctions and one of these died. Five of the 8 patients treated by grafting alone suffered infarction and of these 3 died. The value of intra-aortic balloon pumping in combination with coronary artery by-pass grafting in the management of impending myocardial infarction is discussed. PMID:6968314

    A test program was conducted with the objective of developing a method and equipment for on-line monitoring of installed ball bearings to detect deterioration or impending failure of the bearings. The program was directed at the spin-axis bearings of a control moment gyro. The bearings were tested at speeds of 6000 and 8000 rpm, thrust loads from 50 to 1000 pounds, with a wide range of lubrication conditions, with and without a simulated fatigue spall implanted in the inner race ball track. It was concluded that a bearing monitor system based on detection and analysis of modulations of a fault indicating bearing resonance frequency can provide a low threshold of sensitivity.

    The procedure by means of which the occurrence time of an impending mainshock can be identified by analyzing in natural time the seismicity in the candidate area subsequent to the recording of a precursory seismic electric signals (SES) activity is reviewed. Here, we report the application of this procedure to an M W 5.4 mainshock that occurred in Greece on 17 November 2014. This mainshock (which is pretty rare since it is the strongest in that area for more than half a century) was preceded by an SES activity recorded on 27 July 2014, and the results of the natural time analysis reveal that the system approached the critical point (mainshock occurrence) early in the morning on 15 November 2014.

  12. Ethical dilemmas related to predictions and warnings of impending natural disaster.

    Scientists and policy makers issuing predictions and warnings of impending natural disaster are faced with two major challenges, that is, failure to warn and issuing a false alarm. The consequences of failure to warn can be serious for society overall, for example, significant economic losses, heavy infrastructure and environmental damage, large number of human casualties, and social disruption. Failure to warn can also have serious for specific individuals, for example, legal proceedings against disaster research scientists, as in the L'Aquila earthquake affair. The consequences of false alarms may be less serious. Nevertheless, false alarms may violate the principle of nonmaleficence (do no harm), affect individual autonomy (eg, mandatory evacuations), and may result in the "cry wolf" effect. Other ethical issues associated with natural disasters include the promotion of global justice through international predisaster technical assistance and postdisaster aid. Social justice within a particular country is promoted through greater postdisaster aid allocation to the less privileged. PMID:24481888

    It is prudent to have early diagnosis and timely management of uncal herniation for better management of neurosurgical patients. There are several clinical and radiological armamentariums that aid in early recognition of the condition. Through this case report, we try to highlight a simple bedside clinical sign that can be a valuable adjunct in early recognition of the impending uncal herniation especially in scenarios wherein it is difficult to assess the pupillary size and reactivity correctly. The improvement in the sign also confirms the resolution of the mass effect in the postoperative period. This is especially helpful for doctors working in the periphery or in resource restrained areas, for a timely referral of the patient to tertiary centre.

    Background: We report the first known case of spontaneous, atraumatic Clostridium septicum gangrene occurring in a patient with recurrent endometrial adenocarcinoma. Case: A 63-year-old white female undergoing chemotherapy for recurrent endometrial adenocarcinoma presented with right “arthritis-like” shoulder pain. She denied fever, chills, or shoulder trauma. The patient was afebrile and her blood pressure was 100/50. Her right shoulder and upper extremity were remarkable for an area of dark blue discoloration with crepitus. The white blood cell (WBC) count was 8,200/μl with left shift. Serum creatinine, platelet count, and coagulation studies were normal. Computed tomography revealed gas in the right shoulder tissues. A Gram stain of fluid aspirated from the shoulder demonstrated gram-positive spore-forming rods. She declined surgical intervention and expired within hours of admission. Cultures of the right shoulder eventually grew Clostridium septicum. Conclusion: It is imperative to consider clostridial gangrene in the differential diagnosis for any patient with cancer and a fever of unknown origin. PMID:18475364

    Introduction Primary omental torsion is a rare cause of acute abdomen in adults and presents with variable signs and symptoms. Establishing a preoperative diagnosis may be difficult in the emergency setting. It is rarely diagnosed preoperatively as it mimics common surgical emergencies such as acute appendicitis, appendicular perforation, acute cholecystitis and perforated peptic ulcers and can lead to the clinical deterioration of patient if missed Presentation of case A 47 years old male was taken to the operating room with a diagnosis of appendicular perforation peritonitis and during surgery was found to have a primary omental gangrene with pyoperitoneum, for which omentectomy and peritoneal lavage was performed. Discussion Torsion of the omentum is a condition in which the organ twists on its long axis to such an extent that its vascularity is compromised. Omental torsion can be primary (idiopathic) or secondary, depending on an underlying cause. Primary omental torsion was first described by Eitel in 1899. However, very few cases have been reported. Our case was a rare case presenting with omental gangrene with pyoperitoneum mimicking appendicular perforation peritonitis. Conclusion Primary omental torsion is a rare diagnosis. A high index of clinical suspicion is required for a preoperative diagnosis. In doubtful cases a CT scan may be helpful. Surgical excision of the omentum remains the treatment of choice; however, conservative management may be attempted in an uncomplicated omental torsion. PMID:26945486

    Perineoscrotal gangrene is an acute disease, a rare and severe affection of the perineum, whose evolution is unpredictable and rapidly extensive. The diagnosis is clinical. The paraclinical examinations allow early diagnosis and assessment of anatomical and biological repercussions. We conducted a retrospective study of 45 patients spread over six years, involving a multidisciplinary team consisting of three specialists (urologists, visceral, plastic surgeons). The average age was 52 years. The largely male dominated our series. Fournier gangrene was the most common etiology. We noted five cases of death (11%) in the acute phase, secondary to septic shock (four patients) or multiple organ failure (one patient). The evolution was favorable in 40 other patients in the series, requiring an initial management in intensive care unit, and surgical treatment. The average hospital stay was 17 days. After the acute phase, all patients underwent a surgery for skin coverage, ranging from guided healing (two patients) to musculocutaneous flap of the gracilis (six patients) via the secondary suture (four patients), the burying the testes (18 patients) and half thick skin graft, with a functional and aesthetic result was acceptable, and minimal sequelae. In our series, the most predictive prognostic factors would be the delay of care, sepsis on admission and associated diseases. PMID:21450384

    A 71-year-old woman diagnosed with Fournier's gangrene caused by penetration of a rectal carcinoma was referred to our hospital. Emergency drainage and sigmoid colostomy were performed. Pathological examination of a biopsy sample showed moderately differentiated tubular adenocarcinoma. Abdominoperineal resection with bilateral salpingo-oophorectomy and hysterectomy was performed with curative intent after 4 courses of chemotherapy with S-1 and oxaliplatin. The postoperative pathological diagnosis was StageⅡ (pT4bN0M0). The patient received tegafur/uracil and Leucovorin as adjuvant chemotherapy. Seven months after the curative operation, partial pneumonectomy was performed for the recurrence of the rectal carcinoma in the right lung. Eight months after pneumonectomy, recurrent tumors were observed in the right lung and subcutaneous fat layer of the right buttock along the drainage site. The tumor in the right buttock was excised along with part of the gluteus maximus, and partial pneumonectomy was then performed. Three years and 6 months after the emergency drainage, the patient is alive with no evidence of recurrence. After drainage for rectal carcinoma complicated by Fournier's gangrene, the possibility of recurrence around the drainage site should be considered. PMID:26805341

    We report a case of pyoderma gangrenosum of the penis presenting as Fournier's gangrene. A 77-year-old man who had undergone radiotherapy for localized prostate cancer 16 month earlier, presented with penile pain and fever. Symptoms began with erythema and induration on the dorsal surface of the penile shaft followed by spontaneous purulent drainage with severe pain. Magnetic resonance imaging was unremarkable except for swelling of the penile skin. Biopsy of the ulcerative penile lesion demonstrated a nonspecific inflammation without vasculitis or malignancy. Despite broad-spectrum antibiotics and debridement, the penile lesion extended and new satellite lesions developed as pustules on the glans. Since cultures were negative for aerobic and anaerobic bacteria, a course of intravenous prednisolone was then initiated at 100 mg/day. Within 24 hours the temperature normalized, progression of the penile lesions stopped and became convalescent. The steroid was then tapered and discontinued. The penile lesions healed slowly during the subsequent 1-month period. Based on the clinical course and histopathological findings as well as exclusion of other ulcerative conditions, a diagnosis of pyoderma gangrenosum was made. Penile involvement of this non-infectious ulcerating skin disease has rarely been reported. Pyoderma gangrenosum affecting the penile skin, such as that in present case, may show a similar presentation as Fournier's gangrene. Prompt differential diagnosis is mandatory since effective management for each processes is markedly different. PMID:16050483

    We performed a systematic review of all cases of Fournier's Gangrene (FG) at our hospital over a 12-year period. A total of 26 cases were assessed. Our goal was to determine the mortality rate and to identify risk factors associated with FG. We also wanted to examine three potential prognostic factors in relation to patient survival, including the time delay from emergency room admission to surgery, the initial extent of the disease, and the impact of more than one debridement procedure under general anesthesia. The time between emergency room admission and the beginning of surgical debridement was not statistically different between survivors and non-survivors. The extent of surgical debridement was close to the margin of statistical significance (p = 0.07) and can be considered an index of the extent of the disease. FG extending to the thighs or to the abdominal wall carries a worse prognosis. The number of surgical debridement procedures done under anesthesia was statistically different between survivors and non-survivors. Patients were 4.8 times more at risk of dying if they are required to have more than one surgical debridement under general anesthesia. This presumably reflects persistent gangrene following initial surgical debridement, fluid resuscitation, and wide spectrum antibiotic treatment. PMID:26225189

    Recently in Japan, venous thromboembolism (VTE) [deep vein thrombosis (DVT)/pulmonary thromboembolism (PTE)] has increased with the Westernization of eating habits and the aging of society. In the West, prophylactic guidelines have been discussed for many years, and, unfortunately, Japan falls far behind the West in this area. We developed Japanese Guidelines for VTE prophylaxis based on the 6th ACCP guidelines in 2004. The incidence of perioperative PTE in Japan has been investigated by the Japanese Society of Anesthesiologists since 2002. The rate of perioperative PTE was estimated to be 4.76 per 10,000 operations in 2003. As we expected, it significantly decreased after the guidelines for thromboprophylaxis were issued and the management fee for PTE prophylaxis was covered by health insurance in April 2004. However, mechanical prophylaxis is not sufficient to prevent mortality rates, and advanced prophylaxis by anticoagulants, such as low-molecular-weight heparin/Xa inhibitors along with unfractionated heparin/vitamin K antagonists will be essential. As a result of use of anticoagulants, mortality rates have been significantly decreased recently. PMID:25163326

    Objective: To review clinical data on direct oral anticoagulants (DOACs) used in the acute treatment of venous thromboembolism (VTE) as well as practical considerations when using these products. Data Sources: Searches of PubMed and Google Scholar for VTE, deep vein thrombosis, pulmonary embolism, and relevant drug international nonproprietary names were conducted. Additional online searches were conducted for prescribing information. Study Selection and Data Extraction: Relevant articles on dabigatran, rivaroxaban, apixaban, and edoxaban for the management of VTE compared with oral vitamin K antagonists (VKAs; published between 1966 and December 2015) were reviewed and summarized, together with information on dosing, pharmacokinetics/pharmacodynamics, and drug-drug interactions. Data Synthesis: The DOACs have the potential to circumvent many of the disadvantages of VKAs. At a minimum, they greatly increase the available therapeutic options, thus providing a greater opportunity for clinicians to select a management option that best fits the needs of individual patients. Despite the significant advance that DOACs represent, they are not without risk and require careful consideration of a number of clinical issues to optimize safety and efficacy. Conclusions: The emergence of DOACs for the management of thromboembolic disorders represents a paradigm shift from oral VKAs. The DOACs provide similar efficacy and improved safety in selected patients as compared with VKAs. Clinicians treating VTE need to be familiar with the intricacies involved in using these agents, including the appropriate dose selection for the relevant indication, avoidance of drug-drug and drug-disease interactions, and consideration of dose adjustments in specific clinical situations, such as organ dysfunction.

  8. Denial of impending death: a discourse analysis of the palliative care literature.

    PubMed

    Zimmermann, Camilla

    2004-10-01

    Terminally ill patients and their families are often referred to as being "in denial" of impending death. This study uses the qualitative method of discourse analysis to investigate the usage of the term "denial" in the contemporary hospice and palliative care literature. A Medline search (1970-2001) was performed combining the text words "deny" and "denial" with the subject headings "terminal care", "palliative care" and "hospice care," and restricted to English articles discussing death denial in adults. The 30 articles were analysed using a constant comparison technique and emerging themes regarding the meaning and usage of the words "deny" and "denial" identified. This paper focusses on the theme of denial as an individual psychological process. Three dominant subthemes were distinguished: denial as an unconscious "defence mechanism", denial as "healthy" and denial as temporary. The analysis focusses on the intertextuality of these themes with each other and with previous texts on the denial of death. Elements of the psychoanalytic definition of denial as an unconscious defence mechanism are retained in the literature but are interwoven with new themes on patient choice. The result is an overall discourse that is conflictual and at times self-contradictory but overall consistent with the biomedical model of illness. I suggest that the representation of death denial elaborated in these articles may be related to a larger discourse on dying in contemporary Western society, which both invites patients to participate in the planning of their death and labels those who do not comply.

  9. Impact of neural noise on a sensory-motor pathway signaling impending collision

    PubMed Central

    Jones, Peter W.

    2012-01-01

    Noise is a major concern in circuits processing electrical signals, including neural circuits. There are many factors that influence how noise propagates through neural circuits, and there are few systems in which noise levels have been studied throughout a processing pathway. We recorded intracellularly from multiple stages of a sensory-motor pathway in the locust that detects approaching objects. We found that responses are more variable and that signal-to-noise ratios (SNRs) are lower further from the sensory periphery. SNRs remain low even with the use of stimuli for which the pathway is most selective and for which the neuron representing its final sensory level must integrate many synaptic inputs. Modeling of this neuron shows that variability in the strength of individual synaptic inputs within a large population has little effect on the variability of the spiking output. In contrast, jitter in the timing of individual inputs and spontaneous variability is important for shaping the responses to preferred stimuli. These results suggest that neural noise is inherent to the processing of visual stimuli signaling impending collision and contributes to shaping neural responses along this sensory-motor pathway.

    2013-01-01

    Fournier gangrene (FG) is a necrotizing soft tissue infection involving the superficial and fascial planes of the perineum. In many cases of FG, debridement of the scrotum is necessary, leaving definitive management of the exposed testicles a significant surgical challenge. Frequent incidental trauma to the testicles can cause severe pain, especially in laborers. Practical surgical solutions are few and not well detailed. Various options exist, including creating a neoscrotum with adjacent thigh tissue, split-thickness skin grafts (STSGs), or even creating a subcutaneous thigh pocket. We describe a case of abdominal implantation of bilateral testicles for persistent testicular pain in a case where STSGs did not provide adequate protection, adjacent thigh skin was not available for creation of a neoscrotum, and significant cord contracture occurred. We detail the advantages and disadvantages of the commonly described techniques, including this approach, and how in select individuals this may be a suitable alternative. PMID:24229025

    2016-01-01

    Hepatic artery aneurysms are among the most common visceral artery aneurysms although still relatively rare. Repair of aneurysms >2 cm in diameter is important due to the high rate of rupture and associated mortality. Here, we present a case of a sudden rupture of a hepatic artery aneurysm after presentation with a perforated gangrenous appendicitis. There is increasing evidence that expansion and rupture of abdominal aortic aneurysm is related to degradation of elastin and collagen by matrix metalloproteinases (MMPs). Elastin degradation leads to expansion, while collagen degradation leads to rupture. The activity of MMPs has been shown to be upregulated by both sepsis and peritonitis. Here, we suggest that the inflammation from sepsis and peritonitis led to the activation and/or upregulation of MMPs, which precipitated aneurysm rupture via collagenase activity. PMID:27173883

Solitary fungal organisms causing FG have rarely been reported. The authors describe a case of an elderly man with a history of diabetes who presented with a necrotizing scrotal and perineal soft tissue infection. He underwent emergent surgical debridement with findings of diffuse urethral stricture disease and urinary extravasation requiring suprapubic tube placement. Candida albicans was found to be the single causative organism on culture, and the patient recovered well following antifungal treatment. Fungal infections should be considered as rare causes of necrotizing fasciitis and antifungal treatment considered in at-risk immunodeficient individuals. PMID:25009452

    Fournier's gangrene (FG) requires prompt recognition and management. We report the case of a 68-year-old man who presented with extensive pain and purple discolouration from the right iliac fossa to perineum. Computed tomography demonstrated gas within the right hemiscrotum extending into the inguinal canal and right buttock, with a right pelvic fluid and air collection. At debridement necrotic fluid was arising from the superficial inguinal ring so laparotomy was performed, revealing a grossly inflamed appendix herniating into the inguinal canal; a right hemicolectomy was performed. Unfortunately, the patient went into cardiac arrest and passed away on the operating table. Histological analysis demonstrated acute-on-chronic inflammation involving the appendix. The condition where appendicitis is implicated in FG is usually due to retroperitoneal rupture and tracking into the perineal spaces. This is the first case reported of an inflamed appendix herniating into the inguinal canal and thus causing FG. PMID:25829533

    A 51-year-old man underwent abdominoperineal resection for advanced rectal cancer at a hospital. He attended our outpatient clinic 58 months later with pain in the external genitalia, and was diagnosed with local pelvic recurrence and metastasis to the para-aortic lymph node and both adrenal glands. He received a total of 30 Gy of radiation for analgesia; subsequently, chemotherapy(mFOLFOX6 plus bevacizumab)was initiated. However, extreme left buttock and left femoral pain developed after the 6 courses of chemotherapy. Abdominal CT revealed Fournier's gangrene caused by small intestinal perforation. Emergency drainage under spinal anesthesia was immediately performed. Two additional drainage procedures were required thereafter and an ileostomy was constructed. The patient was discharged 100 days after the initial drainage. This is an extremely rare example of a bevacizumab-related small intestinal perforation that developed into Fournier's gan- grene.

A defunctioning loop sigmoid colostomy was also formed. Subsequent operations required excision of the scrotum and abdominoperineal excision of the rectum. Histology studies later confirmed the presence of necrotising fasciitis.

Material and methods We retrospectively analyzed the data of 39 patients treated for FG in our clinic. Data were collected on medical history, symptoms, physical examination findings, vital signs, laboratory parameters at admission and at the end of treatment, timing and extent of surgical debridement, and the antibiotic treatment used. The Fournier’s Gangrene Severity Index (FGSI) and Charlson Comorbidity Index (CCI) were used to predict outcome. The data were analyzed in relation with the survival of the patients. Mann-Whitney U test, chi -square test, Wilcoxon signed rank test, and Cox regression analysis were used for the statistical analysis. Results Of 39 patients analyzed, 8 (20.5%) died and 31 (79.5%) survived. The median FGSI score on admission was 2 (0–9) for the survivors and 6 (2–14) for the non-survivors (p=0.004). The median CCI scores of the survivors and non-survivors were 2 (0–10) and 6.5 (5–11), respectively (p=0.001). Except for urea, albumin and hematocrit levels, no significant differences were found between survivors and non-survivors for other laboratory parameters on admission. Lower albumin levels and advanced age were found to be associated with mortality. Conclusion High blood urea, low albumin, and low hematocrit levels were associated with poor prognosis. High CCI and FGSI scores could be associated with a poor prognosis in patients with FG.

    The revised guideline of 2013 is an update of the 2005 guideline "venous leg ulcer". In this special project four separate guidelines (venous leg ulcer, varicose veins, compression therapy and deep venous disorders) were revised and developed simultaneously. A meeting was held including representatives of any organisation involved in venous disease management including patient organizations and health insurance companies. Eighteen clinical questions where defined, and a new strategy was used to accelerate the process. This resulted in two new and two revised guidelines within one year. The guideline committee advises use of the C of the CEAP classification as well as the Venous Clinical Severity Score (VCSS) and a Quality of life (QoL) score in the assessment of clinical signs. These can provide insight into the burden of disease and the effects of treatment as experienced by the patient. A duplex ultrasound should be performed in every patient to establish the underlying aetiology and to evaluate the need for treatment (which is discussed in a separate guideline). The use of the TIME model for describing venous ulcers is recommended. There is no evidence for antiseptic or antibiotic wound care products except for a Cochrane review in which some evidence is presented for cadexomer iodine. Signs of infection are the main reason for the use of oral antibiotics. When the ulcer fails to heal the use of oral aspirin and pentoxifylline can be considered as an adjunct. For the individual patient, the following aspects should be considered: the appearance of the ulcer (amount of exudate) according to the TIME model, the influence of wound care products on moisturising the wound, frequency of changing compression bandages, pain and allergies. The cost of the dressings should also be considered. Education and training of patients t improves compliance with compression therapy but does not influence wound healing rates. PMID:24843102

    Epidural venous plexus engorgement may occur due to several conditions that prevent the normal venous circulation. Inferior vena cava agenesis is a very rare cause of epidural venous enlargement. We present a case with a very thin inferior vena cava and left iliac vein agenesis who presented with back pain due to epidural vein engorgement and lacked other venous problems such as deep vein thrombosis.

    Aims: Central venous catheter access in an acute setting can be a challenge given underlying disease and risk for venous thrombosis. Peripherally inserted central venous catheters (PICCs) are commonly placed but limit sites for fistula creation in patients with chronic renal failure (CKD). The aim of this study is to determine the incidence of venous thrombosis from small bore internal jugular (SBIJ) and PICC line placement. This investigation identifies populations of patients who may not be ideal candidates for a PICC and highlights the importance of peripheral vein preservation in patients with renal failure. Materials and methods: A venous Doppler ultrasound was performed at the time of SBIJ insertion and removal to evaluate for thrombosis in the internal jugular vein. Data was collected pre- and post-intervention to ascertain if increased vein preservation knowledge amongst the healthcare team led to less use of PICCs. Demographic factors were collected in the SBIJ and PICC groups and risk factor analysis was completed. Results: 1,122 subjects had PICC placement and 23 had SBIJ placement. The incidence of thrombosis in the PICC group was 10%. One patient with an SBIJ had evidence of central vein thrombosis when the catheter was removed. Univariate and multivariate analysis demonstrated a history of transplant, and the indication of total parenteral nutrition was associated with thrombosis (p < 0.001). The decrease in PICCs placed in patients with CKD 6 months before and after intervention was significant (p < 0.05). Conclusions: There are subsets of patients with high risk for thrombosis who may not be ideal candidates for a PICC. PMID:25997503

    Osteochondromas arising from the interosseous border of the distal tibia and involving distal fibula are uncommon. We present a 16 year old young boy with an impending fracture, erosion and weakness of the distal fibula, secondary to an osteochondroma arising from the distal tibia. Early excision of this deforming distal tibial osteochondroma avoided the future risk of pathological fracture of the distal fibula, ankle deformities and syndesmotic complications. PMID:19187551

    The effect of long and short-term venous hypertension upon lymph fibrinogen concentrations was studied in an attempt to explain the peri-capillary deposition of fibrin reported in patients with post-phlebitic syndromes. The clearance of radioactive fibrinogen/thrombin clots from the subcutaneous tissues of rats and human volunteers was also studied. Both long- and short-term venous hypertension were found to increase fibrinogen transport across the interstitial space by more than 600%. Not only was there evidence of fibrinolytic activity in the lymph but after long-term venous hypertension alpha 2 antiplasmin activity was also detectable. Skin biopsies from the venous hypertensive ankles showed deposition of interstitial fibrin. The clearance of radioactive fibrinogen/thrombin clots from the subcutaneous tissues of the rat was found to be delayed if the rats were given epsilon amino caproic acid but it could not be increased with stanozolol. In human subjects it was found that patients with lipodermatosclerosis had delayed clot clearance and retarded blood fibrinolytic activity when compared with normal volunteers and patients with uncomplicated varicose veins. The principle cause why tall men are more subject to ulcers than short men, Dr Young conceived to be then length of the column of blood in their veins; which by its pressure, renders the legs less able to recover when hurt by any violence.

    Deep vein thrombosis and pulmonary embolism, considered to be different manifestations of the same disease - venous thromboembolism, have few differences regarding the anticoagulant treatment. However, there are some issues which will be discussed. The therapy objectives in patients with venous thromboembolism include: prevention of death by pulmonary embolism, relieving symptoms in the affected leg, preventing morbidity and prevention of recurrent thromboembolism or postthrombotic syndrome, or minimize symptoms of post-thrombotic syndrome. For most patients, treatment goals are achieved using appropriate anticoagulant therapy, reducing the risk of recurrence in the first three months after diagnosis from over 25% to under 4%. Using of compression socks, providing a gradient of 30-40 mmHg at the ankle for 2 years after the diagnosis, reduce the risk of postthrombotic syndrome. Thrombolysis, applied either systemic or directly by catheter, is indicated in selected cases to prevent onset of postthrombotic syndrome or remove quickly the symptoms due to high venous obstruction. Thrombolytic therapy should be continued with anticoagulant therapy to prevent recurrence of venous thromboembolism. The use of an inferior vena cava filter is indicated for prevention of death by pulmonary embolism in patients who have contraindications to anticoagulant therapy, or anticoagulant treatment that was properly administered remains inefficient. Surgical treatment is recommended in case of chronic pulmonary hypertension, due to thromboembolic disease. PMID:23781572

    There has recently been increased publicity on the risk of venous thrombosis after long-haul flights. This paper reviews the evidence base related to the association between air travel and venous thromboembolism. The evidence consists only of case reports, clinical case-control studies and observational studies involving the use of intermediate end-points, or expert opinion. Some studies have suggested that there is no clear association, whereas others have indicated a strong relationship. On the whole it appears that there is probably a link between air travel and venous thrombosis. However, the link is likely to be weak, mainly affecting passengers with additional risk factors for venous thromboembolism. The available evidence is not adequate to allow quantification of the risk. There are insufficient scientific data on which to base specific recommendations for prevention, other than that leg exercise should be taken during travel. Further studies are urgently needed in order to identify prospectively the incidence of the condition and those at risk. PMID:12077617

    Abstract Fournier gangrene is a rare but highly infectious disease characterized by fulminant necrotizing fasciitis involving the genital and perineal regions. Negative pressure wound therapy (NPWT; KCI USA Inc, San Antonio, TX) is a widely adopted technique in many clinical settings. Nevertheless, its application and effect in the treatment of Fournier gangrene are unclear. A 47-year-old male patient was admitted with an anal abscess followed by a spread of the infection to the scrotum, which was caused by Pseudomonas aeruginosa. NPWT was applied on the surface of the scrotal area and continued for 10 days. A split-thickness skin graft from the scalp was then grafted to the wound, after which, NPWT utilizing gauze sealed with an occlusive dressing and connected to a wall suction was employed for 7 days to secure the skin graft. At discharge, the percentage of the grafted skin alive on the scrotum was 98%. The wound beside the anus had decreased to 4 × 0.5 cm with a depth of 1 cm. Follow-up at the clinic 1 month later showed that both wounds had healed. The patient did not complain of any pain or bleeding, and was satisfied with the outcome. NPWT before and after split-thickness skin grafts is safe, well tolerated, and efficacious in the treatment of Fournier gangrene. PMID:25654376

    Venous ulcers affect approximately 1% of the world's population, increasing healthcare expenditures and decreasing quality of life. Several hypotheses may help explain their origin. Incompetent veins or valves or impaired muscle function may lead to abnormal calf muscle pump function that can elevate ambulatory venous pressure (venous hypertension). This hypertension subsequently results in local venous dilatation and pooling, concomitantly trapping leukocytes that may release proteolytic enzymes that destroy tissues. Venous pooling also induces interendothelial pore widening and deposition of fibrin and other macromolecules that "trap" growth factors within them, rendering them unavailable for wound repair. Compression therapy, the mainstay treatment, reduces edema, reverses venous hypertension, and improves calf muscle pump function. Several treatment options can be employed as adjuvants to compression--eg, systemic therapy with pentoxifylline or aspirin, autologous grafts, tissue-engineered skin, growth factor therapy, and/or vein surgery. The epidemiology, pathophysiology, diagnosis, and management options regarding venous ulcers are reviewed. PMID:16014984

    Objectives: To describe the characteristics and prognostic factors of 28 patients with Fournier’s Gangrene (FG) referred to our medical center at Southeastern Iran. Methods: This was a cross-sectional study including 28 cases of FG that were operated in Surgery department of Zahedan University of Medical Sciences during a 10-year period from April 2002 to March 2012. The study analyzed 9 parameters including the body temperature, heart rate, respiratory rate, hematocrit, white blood count (WBC), and serum levels of sodium, potassium, creatininee (twice for 2 for acute renal failure), and bicarbonate for Fournier Gangrene Severity Index (FGSI) score. The aspects taken into account were age, gender, predisposing factors, duration of symptoms, hospitalization period, and number of debridements, disease outcome and the FGSI. Results: All patients were males, aged from 26 to 68 years, with mean age 44.6 ±8.49 years. Statistically significant differences in age (p<0.001), duration of symptoms (p=0.001), number of debridements (p=0.006), hospitalization duration (p<0.001) and FGSI (p<0.001) were found between surviving and dead patients. The mortality rate was 35.7%, and the most common presentation was perianal/scrotal pain (78.6%). Perianal and primary scrotal abscesses were most common causes of FG and were found in 57.14% and 21.42% of patients respectively. The most prevalent predisposing factor was diabetes mellitus in 12 (42.85%) patients. With respect to laboratory findings, statistically significant differences in WBC (p=0.002), creatinine (p<0.001), albumin (p<0.001), calcium (p<0.001) and serum sodium (p=0.035) were found between the surviving and dead patients. Conclusion: Serious outcome of FG was associated with old age, delayed diagnosis and treatment, inadequate surgical debridement, shorter hospitalization and higher FGSI scores. In addition higher WBC, higher creatininee and serum sodium and lower albumin and calcium levels implicated worse prognosis

    An understanding of heart-circulation interaction is crucial to our ability to guide our patients through an episode of septic shock. Our knowledge has advanced greatly in the last one hundred years. There are, however, certain empirical phenomena that may lead us to question the wisdom of our prevailing treatment algorithm. Three extreme but iatrogenically possible haemodynamic states exist. Firstly, inappropriately low venous return; secondly, overzealous arteriolar constriction; and finally, misguided inotropy and chronotropy. Following an unsuccessful fluid challenge, it would be logical to first set the venous tone, then set the cardiac rate and contractility, and finally set the peripheral vascular resistance. It is hypothesized that a combination of dihydroergotamine, milrinone and esmolol should be superior to a combination of noradrenaline and dobutamine for surviving sepsis. PMID:25245463

    Cerebral venous thrombosis (CVT) is a potentially life-threatening emergency. The wide ranging of clinical symptoms makes the use of imaging in "slices" even more important for diagnosis. Both CT and MRI are used to diagnose the occlusion of a venous sinus, but MRI is superior to CT for detecting a clot in the cortical or deep veins. CT can show the hyperintense clot spontaneously and CT angiography the intraluminal defect. MRI also detects this thrombus, whose signal varies over time: in the acute phase, it is hypointense in T2*, whilst T1 and T2 can appear falsely reassuring; in the subacute phase, it is hyperintense on all sequences (T1, T2, FLAIR, T2*, diffusion). MRI easily shows the ischemic damage, even hemorrhagic, in the cerebral parenchyma in cases of CVT. Finally, imaging may reveal pathology at the origin of the CVT, such as a fracture of the skull, infection, tumor, dural fistula, or intracranial hypotension. PMID:25465119

    Seven patients with venous thrombosis and contraindications to traditional thrombolytic therapy, consisting of recent intracranial surgery, recent pineal or retroperitoneal hemorrhage, active genitourinary or gastrointestinal bleeding, epidural procedures, and impending surgery, were successfully treated with a modified thrombolytic regimen. To improve safety, prolonged continuous infusions of tissue plasminogen activator (tPA) was eliminated in favor of once-daily low-dose intraclot injections of tPA to minimize the amount and duration of tPA in the systemic circulation, and low-therapeutic or regional anticoagulation was used to reduce anticoagulant risks. These modifications may allow thrombolytic treatment for selected patients with severe venous thrombosis who are deemed to be at high risk. PMID:23273695

    Forty patients with chronic venous insufficiency (CVI) and varices of the legs were selected and double-blindly randomly assigned to a treatment with Pycnogenol (French maritime pine bark extract), 100 mg x 3/day or a placebo for 2 months, according to a double-blind experimental design. The effects of the treatment were evaluated by scoring the symptomatology with a semi-quantitative scale, and the venous blood flow by means of a hand-held Doppler ultrasound. The tolerability was evaluated by recording the adverse effects and by means of hematology and blood chemistry parameters, before and at the end of the treatment. Pycnogenol treatment induced a significant reduction in subcutaneous edema as well as heaviness and pain in the legs, on both after 30 and 60 days, the evaluation time periods. Approximately 60% of patients treated with Pycnogenol(R) experienced a complete disappearance of edema (the most rapidly disappearing symptom) and pain at the end of the treatment, while almost all the patients reported a reduction in leg heaviness which disappeared in approximately 33% of patients. These changes were statistically significant. No effect was observed in the placebo-treated subjects. No effect on the venous blood flow was observed in either of the experimental groups.

    The Clostridia species are responsible for some of the deadliest diseases including gas gangrene, tetanus, and botulism. Clostridium septicum is a rare subgroup known to cause atraumatic myonecrosis and is associated with colonic malignancy or immunosuppression. It is a Gram-positive, anaerobic, spore-forming bacillus found in the gastrointestinal tract and can lead to direct, spontaneous infections of the bowel and peritoneal cavity. The anaerobic glycolysis of the tumor produces an acidic, hypoxic environment favoring germination of clostridial spores. Tumor-induced mucosal ulceration allows for translocation of sporulated bacteria from the bowel into the bloodstream, leading to fulminant sepsis. C. septicum bacteremia can have a variable presentation and is associated with greater than 60% mortality rate. The majority of deaths occur within the first 24 hours if diagnosis and appropriate treatment measures are not promptly started. We report a case of abdominal myonecrosis in a patient with newly diagnosed colon cancer. The aim of this study is to stress the importance of maintaining a high suspicion of C. septicum infection in patients with underlying colonic malignancy. PMID:26793397

    We report a case of gangrene, which developed following an open fracture of the femur immobilized with an external fixator in a 45-year-old patient. A conventional vacuum dressing (VAC Therapy) could not be applied with the external fixator in place. An original vacuum dressing was thus fashioned after surgical debridement. Scabs were covered with calcium alginate. The lower limb was enveloped in sterile dressings and vacuum was achieved by suction with gastric tubes under adhesive films. The dressing was redone every 48 h in a surgical setting. Antibiotic prophylaxis enabled cure of the infection. Budding appeared within two weeks enabling skin grafting. Centro-medullary nailing was undertaken on day 30 to accelerate bone healing. At three months from the trauma, the initial loss of sensitivity in the leg and foot noted at the first weight bearing required programmed disarticulation of the knee after femur and wound healing. At six months, the patient had resumed his occupational activities and was pain free. This type of dressing could be useful for tissue loss over a fracture immobilized with an external fixator. This type of assembly can easily be installed in the operating room. PMID:18342034

    Abstract Background: Clostridium perfringens gas gangrene is an extremely rare and fatal infection. Necrosis of the myometrium is rarely seen and has only been recorded in 18 cases to date. Of these 18 reported cases, only 5 have occurred in nonpregnant women. This article presents the 6th case of myometrium necrosis from C. perfringens. Case: A 72-year-old woman, gravida 2, para 2, presented with abdominal pain and vaginal bleeding. After examinations, laboratory testing, and several surgical interventions, she was found to have C. perfringens infection and advanced high-grade serous adenocarcinoma of the endometrium with >50% invasion into the myometrium. Results: Despite the surgical interventions and use of several antibiotics, this patient did not improve. She was weaned from treatment per her advance directive and died after weaning. Conclusions: Awareness of the many etiologies for peritonitis is of great importance when a fatal infection may be the cause of the condition. Correct diagnosis and proper treatment is essential for the survival of patients infected with C. perfringens. (J GYNECOL SURG 32:182) PMID:27274183

    Objectives: To evaluate the effect of immune failure and/or diabetes mellitus (DM) association on the mortality and morbidity of the Fournier's Gangrene (FG), and interrelatedly, the usability of HbA1c level in the prediction of prognosis. Materials and Methods: The data of 38 patients with the diagnosis of FG were investigated retrospectively. The patients were divided into two groups as patients with DM (Group 1, n = 18) and non-diabetics (Group 2, n = 20). The patients in group 1 were also divided into two subgroups as patients with HbA1c value ≥7 (Group 1a) and HbA1c value <7 (Group 1b). Results: The mean age of all 38 male patients was 66.3 ± 6.4 years. The initial symptoms were scrotal rash and swelling (n = 20, 52.6%), high fever (>38°C) (n = 22, 57.8%), purulent discharge from genital or perineal areas (n = 13, 34.2%), skin bruises (n = 11, 28.9%) and general state disorder in five patients that were admitted from day care center (13.1%). DM, as the most often comorbid disease, was detected in 18 patients (47.3%). Six patients (15.7%) were deceased during the follow-up period. Conclusion: In the present study, the researchers determined that diabetic patients with HbA1c level of 7 or higher had worse prognosis, and increased mortality. PMID:27453658

    2015-01-01

    Fournier’s gangrene (FG) is a rapid progressive bacterial infection that involves the subcutaneous fascia and part of the deep fascia but spares the muscle in the scrotal, perianal and perineal region. The incidence has increased dramatically, while the reported incidence of rectal cancer-induced FG is unknown but is extremely low. Pathophysiology and clinical presentation of rectal cancer-induced FG per se does not differ from the other causes. Only rectal cancer-specific symptoms before presentation can lead to the diagnosis. The diagnosis of rectal cancer-induced FG should be excluded in every patient with blood on digital rectal examination, when urogenital and dermatological causes are excluded and when fever or sepsis of unknown origin is present with perianal symptomatology. Therapeutic options are more complex than for other forms of FG. First, the causative rectal tumor should be removed. The survival of patients with rectal cancer resection is reported as 100%, while with colostomy it is 80%. The preferred method of rectal resection has not been defined. Second, oncological treatment should be administered but the timing should be adjusted to the resolution of the FG and sometimes for the healing of plastic reconstructive procedures that are commonly needed for the reconstruction of large perineal, scrotal and lower abdominal wall defects.

    Repeated daily dosing of mice with 4-vinylcyclohexene diepoxide (VCD) causes a gradual onset of ovarian failure, providing a model for perimenopause. Because increasing numbers of women are delaying starting a family, infertility in aging women is of concern. This study was designed to determine the effects of impending ovarian failure on fertility in VCD-treated mice. Female C57BL/6J mice were dosed daily (17 d) with vehicle control or VCD (160 mg/kg, intraperitoneally) to deplete primordial follicles and then were divided into 2 groups. Group 1 was mated soon after dosing; group 2 was mated on day 20 after dosing, during impending ovarian failure. Fertility was evaluated on gestational day 16. In group 1, cycle length, pregnancy rate, and number of live fetuses did not differ between VCD-treated animals and controls, but VCD-treated mice required more matings to become pregnant and had more resorptions. In group 2, VCD-treated mice demonstrated proestrus and copulatory plugs, but only 1 animal became pregnant, and she had no viable fetuses. Ovaries from pregnant and nonpregnant controls contained similar numbers of follicles and corpora lutea. Ovaries from VCD-treated animals contained no follicles, and corpora lutea were seen only in pregnant animals. In VCD-treated mice mated soon after dosing, conception was more difficult and more resorbed fetuses were seen, whereas in those mated closer to impending ovarian failure, no successful pregnancies were achieved. These results demonstrate that VCD-treated mice can be used to model infertility in perimenopausal women. PMID:17974126

    Use of a spring-loaded silastic silo has been advocated as a means of gentle reduction of the herniated bowel, while avoiding the possible complications of primary closure of gastroschisis. We recently encountered intestinal venous congestion during elective silo reduction of gastroschisis. Two babies with gastroschisis were treated postdelivery with a spring-loaded silo placed under the fascial defect and the eviscerated bowel suspended within the silo. Patient #1 had no bowel matting. On day of life 2, the bowel within the silo was noted to be dusky. The silo was removed, and the bowel was indeed congested, but viable. Complete reduction with a modified Bianchi closure was performed at the bedside. Patient #2 had severe matting of the bowel and did not require intubation for silo placement. As daily reductions progressed, the bowel was noted to be congested on day 2. On day 3, removal of the silo revealed frank bowel necrosis with impending perforation. Two-thirds of the small bowel required resection, leaving the child with short bowel. Venous congestion within a silo should be given prompt attention, including removal of the silo, as bowel infarction may result. PMID:19349001

    Venous ulceration of the lower extremities is a common and often disabling condition. Venous ulcers are the result of a chronic inflammatory condition caused by persistent venous hypertension. Therapy is directed at counteracting the chronic inflammation in the tissues and at decreasing ambulatory venous hypertension in the area. Compression therapy helps decrease the venous hypertension and aids healing. Topical agents may be used to help decrease the bacterial load in the wound, provide a moist healing environment for dry wounds, or absorb the exudate in wounds with a lot of drainage. Pharmacological adjuncts, such as pentoxifylline or flavanoids, may help counteract the chronic inflammation in the ulcerated area. Interventions to decrease the ambulatory venous hypertension can help patients with either active or healed ulcers. Ablation of incompetent superficial truncal veins and/or perforating veins using radiofrequency ablation, endovenous laser ablation, or foam sclerotherapy can speed ulcer healing and prevent recurrence.

    The use of smaller cannulae for minimally invasive surgery techniques and/or aggressive miniaturization of the cardiopulmonary bypass (CPB) circuitry has necessitated the need to augment venous drainage to achieve adequate flow rates. Vacuum assisted venous drainage (VAVD) has become the dominant method to augment venous drainage. VAVD, however, has been associated with a number of known side effects including increased transmission of gaseous microemboli to the patient, venous line chatter, and increased arterial to venous shunts in the circuit. Historically, our practice has been to monitor the arterial output flow rate and to monitor VAVD by observing venous line chatter and changes in the venous reservoir level. In 2008 our pediatric cardiothoracic service began monitoring venous line flow rates by using a second ultrasonic flow probe placed on the venous line. After 12 months, our staff perfusionists reviewed the impact of monitoring venous line flow rates on VAVD and its known side effects on daily clinical practice. When monitoring venous line flow rates, empiric observation revealed that less overall vacuum pressure was needed for our CPB cases. This novel approach to monitoring venous drainage has aided us in providing optimal vacuum levels and therefore, may reduce some of the known side effects experienced with excessive VAVD.

  7. The precursory fault width formation and critical stress state of impending large earthquakes: The observation and deterministic forecasting

    2009-12-01

    Dividing Japan into meshes of about 5 degrees, we collect earthquakes (EQs) for each mesh-area from an on-line JMA focus catalog of Japan with a regionally dependent magnitude window of M ≥ 3-3.5. The time history of each mesh-collection is a string of EQ events, which draw a zigzagged trajectory in a physical space. The space coordinates are the EQ epicenter, focal depth (DEP), inter-EQ time interval (INT), and magnitude (MAG). Thus, each coordinate component of the trajectory is the time series of the corresponding EQ source parameter where time is the chronological event index. The zigzagged motion appears random like Brownian motion; however, it is a deterministic chaos. The evidence is that the largest Lyapunov exponents of each trajectory are all positive, statistically distinct from those surrogated by randomly shuffling only the event index. Thus, the deterministic chaos suggests that any impending large EQ does not rupture randomly and that some deterministic seismogenesis controls the rupture process. Namely, some short-term deterministic forecasting is theoretically possible. Therefore, we first take a moving-average of 15-25 events on each series to reduce the zigzagged motion. We further take its second order difference at the interval of 20-35 events to find its acceleration (seismogenic force) acting on each averaged series. We then find only two unique different triple phase couplings of the acceleration on source parameter DEP, INT, and MAG precursory to every impending large EQs (M > about 6) throughout Japan [Takeda, 2003; Takeda and Takeo, 2004]. Each triple phase coupling begins the MAG with medium MAG of about 4.1 at either small (shallow) DEP and large INT or large (deep) DEP and small INT, then change it to small MAG of about 3.8 at either deep DEP and small INT or shallow DEP and large INT. The transition of the EQ state creates a large linear DEP variation (W) on its series, which is found comparable to the fault width of large EQs

    We report an interesting case of Buerger’s disease that manifested at the glans penis in a 56 year-old former smoker. Penile involvement in Buerger’s disease is rare. Our patient had no prior extremity or digit amputations in his 4-year history of Buerger’s disease. However, our patient did suffer from recurrent penile ulcers over an 8-week timeframe that ultimately progressed to a gangrenous, unsalvageable glans penis. He underwent a partial penectomy and urethral reconstruction with excellent post-operative results. PMID:27069957

    Central venous catheter placement is indicated in many situations, and an increasing number of patients require temporary and long-term central catheters. Frequently, patients who have undergone multiple central veins catheterizations develop complete and diffuse venous occlusion, and this constitutes a difficult-to-manage clinical problem. We report a case of a 20-year-old patient who was referred to our department for central venous line placement who manifested bilateral femoral, jugular, and subclavian veins occlusion. A central venous catheter was implanted through a cervical collateral vein, targeting on and puncturing an angioplasty balloon, and advanced into the collateral vein through a transhepatic venous access.

    Purpose: To report on the efficacy of fixing fresh venous thrombus to the venous wall by stent placement. Methods: Seven patients underwent stenting to treat acute venous thrombosis. In two patients, the hemodialysis fistula was thrombosed with the thrombus extending into the brachial veins. In three patients, the hemodialysis fistula was patent but massive swelling of the ipsilateral arm was caused by proximal venous thrombosis. Two patients presented with iliac venous thrombosis within stented pelvic veins. Stent placement was preceded by other mechanical thrombectomy methods in all cases. Results: Attachment of thrombus to the venous wall was successful in all cases treated. Acute rethrombosis did not occur. Follow-up patency in dialysis patients was 7.2 {+-} 2.1 months. One patient had rethrombosis of the dialysis graft 3 months after primary treatment. Three patients developed restenosis within a mean period of 7.7 months. One shunt remained patent for 10 months with no event of reobstruction during follow-up. In both patients with iliac stent placement, the vein remained patent over a follow-up period of 8 and 12 months respectively. Conclusion: Stenting fresh venous thrombus can achieve immediate venous patency. It may be used as an alternative approach when all other percutaneous methods fail. Frequent restenosis within stented veins limits its use to very selected cases.

    The aim of this study is to declare our experience and to identify the important factors that influence the mortality and morbidity in patients with combat-related penetrating wounds of the abdomen (CR-PWA) with major venous vessel injuries. Twenty-six wounded with combat-related injuries of major abdominal venous vessels, admitted in the University Clinic cardiovascular surgery department during the period from 1 August 1991 through 30 October 1995, were analyzed. Patients with concomitant injured arteries and extra-abdominal injuries (n=150; 85.2%) were excluded from this study. The Penetrating Abdominal Trauma Index (PATI) score for each patient was calculated. Fifteen patients (57.69%) sustained with PATI score greater than 25 died. The mean duration of hospitalization was 16 days (range 0-86). The average hospitalization time for those surviving their complications was 17 days with a PATI of 25 or less, and 43 days with a score more than 25. Three clinical assessments of the long-term outcome were performed after a median of about 3, 5 and 10 years, respectively. Surviving patients (42.31%) were symptom free and had normal Duplex scans as well as no other surgical related complications. Higher PATI scores, postoperative complications and reoperations exert an unfavorable effect on patient outcome. PMID:18006557

    Septic cerebral venous sinus thrombosis, once a common and deadly disease, has fortunately become rare now. Not only that the incidence has fallen significantly after the antibiotic era, the morbidity and mortality has also decreased substantially. Cavernous sinus thrombosis is by far the commonest form of septic cerebral venous sinus thrombosis. Due to its rare occurrence, a lot of current generation clinicians have not encountered the entity in person. Despite all the advances in diagnostic modalities, a high index of clinical suspicion remains the mainstay in prompt diagnosis and management of this potentially lethal condition. Keeping this in view, the authors have reviewed the subject including the old literature and have summarized the current approach to diagnosis and management. Septic cavernous thrombosis is a fulminant disease with dramatic presentation in most cases comprised of fever, periorbital pain and swelling, associated with systemic symptoms and signs. The preceding infection is usually in the central face or paranasal sinuses. The disease rapidly spreads to contralateral side and if remains undiagnosed and untreated can result in severe complications or even death. Prompt diagnosis using radiological imaging in suspected patient, early use of broad spectrum antibiotics, and judicial use of anticoagulation may save the life and prevent disability. Surgery is used only to treat the nidus of infection. PMID:26944152

    Varicose veins without skin changes have a prevalence of approximately 20% in Northern and Western Europe whereas advanced chronic venous insufficiency affects about 3% of the population. Genetic risk factors are thought to play an important role in the aetiology of both these chronic venous diseases (CVD). We evaluated the relative genetic and environmental impact upon CVD risk by estimating the heritability of the disease in 4,033 nuclear families, comprising 16,434 individuals from all over Germany. Upon clinical examination, patients were classified according to the CEAP guidelines as either C2 (simple varicose veins), C3 (oedema), C4 (skin changes without ulceration), C5 (healed ulceration), or C6 (active ulcers). The narrow-sense heritability (h2) of CVD equals 17.3% (standard error 2.5%, likelihood ratio test P = 1.4 × 10−13). The proportion of disease risk attributable to age (at ascertainment) and sex, the two main risk factors for CVD, was estimated as 10.7% (Kullback–Leibler deviance R2). The heritability of CVD is high, thereby suggesting a notable genetic component in the aetiology of the disease. Systematic population-based searches for CVD susceptibility genes are therefore warranted. PMID:20354728

    Based on the Fick law, coronary venous blood oxygen measurements have value for assessing functional parameters such as the coronary flow reserve. At present, the application of this measure is restricted by its invasive nature. This report describes the design and testing of a noninvasive coronary venous blood oxygen measurement using MRI, with a preliminary focus on the coronary sinus. After design optimization including a four-coil phased array and an optimal set of data acquisition parameters, quality tests indicate measurement precision on the order of the gold standard optical measurement (3%O(2)). Comparative studies using catheter sampling suggest reasonable accuracy (3 subjects), with variability dominated by sampling location uncertainty ( approximately 7%O(2)). Intravenous dipyridamole (5 subjects) induces significant changes in sinus blood oxygenation (22 +/- 9% O(2)), corresponding to flow reserves of 1.8 +/- 0.4, suggesting the potential for clinical utility. Underestimation of flow reserve is dominated by right atrial mixing and the systemic effects of dipyridamole. Magn Reson Med 42:837-848, 1999. PMID:10542342

    To determine whether the body fluid shift from the lower limbs toward the head that occurs during spaceflight leads to lasting increases of venous pressure in the upper body, venous pressure and hematocrit measurements were made on four astronauts before flight and 1 and 12 hours after recovery and compared with measurements in space. During the mission the hematocrit was elevated and the venous pressure lowered by 1 to 8 centimeters of water as compared with the preflight data. One hour after landing the hematocrit decreased, indicating a hemodilution, venous pressures were unexpectedly high, and a body weight loss of 4 to 5 percent was observed. Twelve hours later the venous pressures were the lowest recorded during the study. The fluid shift apparently takes place during the first several hours of spaceflight. Thereafter, the pressure in the peripheral veins and the central circulation is lower than that measured before flight.

The patient had also undergone transplantation of the left kidney in the past. She was initially admitted to the Department of Traumatology for a total endoprosthesis procedure due to bionecrosis of the head of the thigh bone. Postoperatively, the patients condition was complicated by gangrene of the colon confirmed by CT scan and during the operation. The patient was operated on - subtotal colectomy, terminal ileostomy and left-sided ovariectomy was performed. The postoperative course was complicated by perforation of the jejunum which was sutured. The patient was admitted to ICU and, after recovery, to our surgical department. Because of the metabolic disturbance she was treated in the internal medicine department. After 60 days she was discharged in a good condition, walking and with full per os realimentation.Key words: lupus erythematosus gangrene of the colon acute abdomen. PMID:25659257

    Human venous compliance hypothetically decreases from upper to lower body as a mechanism for maintenance of the hydrostatic indifference level 'headward' in the body, near the heart. This maintains cardiac filling pressure, and thus cardiac output and cerebral perfusion, during orthostasis. This project entailed four steps. First, acute whole-body tilting was employed to alter human calf and neck venous volumes. Subjects were tilted on a tilt table equipped with a footplate as follows: 90 deg, 53 deg, 30 deg, 12 deg, O deg, -6 deg, -12 deg, -6 deg, O deg, 12 deg, 30 deg, 53 deg, and 90 deg. Tilt angles were held for 30 sec each, with 10 sec transitions between angles. Neck volume increased and calf volume decreased during head-down tilting, and the opposite occurred during head-up tilt. Second, I sought to cross-validate Katkov and Chestukhin's (1980) measurements of human leg and neck venous pressures during whole-body tilting, so that those data could be used with volume data from the present study to calculate calf and neck venous compliance (compliance = (Delta)volume/(Delta)pressure). Direct measurements of venous pressures during postural chances and whole-body tilting confirmed that the local changes in venous pressures seen by Katkov and Chestukhin (1980) are valid. The present data also confirmed that gravitational changes in calf venous pressure substantially exceed those changes in upper body venous pressure. Third, the volume and pressure data above were used to find that human neck venous compliance exceeds calf venous compliance by a factor of 6, thereby upholding the primary hypothesis. Also, calf and neck venous compliance correlated significantly with each other (r(exp 2) = 0.56). Fourth, I wished to determine whether human calf muscle activation during head-up tilt reduces calf venous compliance. Findings from tilting and from supine assessments of relaxed calf venous compliance were similar, indicating that tilt-induced muscle activation is

    Angiodysplasia of the extremities is a broad group of vascular lesions of arterial, capillary, and venous origin. They are generally detected initially during late childhood or early adulthood. Although they may cause swelling and pain, they are often asymptomatic and are discovered incidentally on physical examination performed for other reasons. One of the most troublesome diagnostic aspects of these lesions is the fact that while they consist of enlarged venous channels, standard venographic techniques may fail to demonstrate them. Three cases are described in which the diagnosis of venous angioma was made by direct needle puncture and contrast material injection, after arteriographic and/or venographic examination was either negative or nondiagnostic.

    The prime objective of this International Microgravity Laboratory (IML-1) investigation is to measure the bulk compliance (distensibility) of the veins in the lower leg before, during, and after spaceflight. It is of particular interest whether venous compliance over the range of both positive and negative transmural pressures (various states of venous distention and collapse) changes throughout the duration of spaceflight. Information concerning the occurrence and character of compliance changes could have implications for the design of improved antigravity suits and further the understanding of inflight and postflight venous hemodynamics.

    Until recently, medical literature and the practice of vascular medicine focused on the cosmetic aspects of venous disease and the advanced stages of venous insufficiency such as painful varicose veins and venous ulcers. The systemic effects of venous insufficiency resulting from a reduction of venous return and increased transit time of blood from the lower extremities that can mimic heart failure are only recently being recognized. This article reviews the diagnosis and treatment options for the patients with venous insufficiency, and increases awareness about the systemic effects of venous disease and its role in the practice of cardiovascular medicine.

    The use of venous flaps is controversial. The mechanism of perfusion of venous flaps is still not fully understood. The research was conducted on 56 white rats. In our experimental work we studied two different models of venous flaps: pedicled venous flap (PVF) and pedicled arterialized venous flap (PAVF). Our results showed that postoperative congestion was present in all flaps. However 66.7% of all pedicled venous flaps and 100% of all pedicled arterialized venous flaps eventually survived. Histological examination revealed that postoperatively the blood flow in the skin of the pedicled arterialized venous flap became «re-reversed» again; there were no differences between mechanism of survival of venous flaps and other flaps. On the 7-14th day in the skin of all flaps were processes of neoangiogenesis and proliferation. Hence the best scenario for the clinical use of venous flaps unfolds when both revascularization and skin coverage are required.

    Venous malformations arising from the peripheral nerve are a rare type of vascular malformation. We present the first case of an intraneural venous malformation of the median nerve to be reported in a child and review the previous two cases of median nerve compression due to a venous malformation that have been reported. These cases presented with painless masses in the volar aspect of the wrist or with symptoms suggestive of carpal tunnel syndrome. Clinical suspicion should lead to the use of Doppler ultrasonography as the first-line diagnostic tool. Magnetic resonance imaging and histopathology can confirm the diagnosis, as phleboliths are pathognomonic of venous malformations. Surgical treatment appears to be the only modality capable of successfully controlling the growth of an intraneural malformation. Sclerotherapy and radiotherapy have never been used to treat this type of malformation. PMID:27462571

    We report the treatment and outcomes of 12 patients who underwent subfascial endoscopic perforator surgery for severe chronic venous insufficiency and venous ulceration. All patients had received prior superficial venous ablative surgery and presented with incompetent perforating veins in the calf and persistent venous ulceration (lasting >10 years). Outcome measures included ulcer healing time, recurrence, clinical symptom, and disability scores. There was one wound complication after subfascial endoscopic perforator surgery. The cumulative ulcer healing rate was 25% at 3 months, 42% at 6 months, and 92% at 1 year. One patient developed ulcer recurrence at 12 months after surgery. The mean clinical score and disability score decreased from 13.00 (standard deviation, 2.26) to 4.83 (1.47) and 1.75 (0.45) to 0.50 (0.52), respectively (P<0.001) after a median follow-up of 15.0 months (interquartile range, 12.0-21.5 months). Subfascial endoscopic perforator surgery was safe and effective in the treatment of patients with severe chronic venous insufficiency and venous ulceration caused by incompetent perforating veins in the calf.

    This paper addresses the question of whether or not interstitial fluid flow due to the blood circulation accounts for the observed periosteal bone formation associated with comprised venous return (venous stasis). Increased interstitial fluid flow induced by increased intramedullary pressure has been proposed to account for the periosteal response in venous stasis. To investigate the shear stresses acting on bone cell processes due to the blood circulation-driven interstitial fluid flow, a poroelastic model is extended to the situation in which the interstitial fluid flow in an osteon is driven by the pulsatile extravascular pressure in the osteonal canal as well as by the applied cyclic mechanical loading. Our results show that under normal conditions, the pulsatile extravascular pressure in the osteonal canal due to cardiac contraction (10mm Hg at 2 Hz) and skeletal muscle contraction (30mm Hg at 1 Hz) induce peak shear stresses on the osteocyte cell processes that are two orders of magnitude lower than those induced by physiological mechanical loading (100 microstrain at 1 Hz). In venous stasis the induced peak shear stress is reduced further compared to the normal conditions because, although the mean intramedullary pressure is increased, the amplitude of its pulsatile component is decreased. These results suggest that the interstitial fluid flow is unlikely to cause the periosteal bone formation in venous stasis. However, the mean interstitial fluid pressure is found to increase in venous stasis, which may pressurize the periosteum and thus play a role in periosteal bone formation. PMID:14499293

    The antithrombotic management of venous thromboembolism (VTE) has gone through major developments. Indirect inhibitors such as low molecular weight heparin and the pentasaccharide fondaparinux represent improvements over traditional drugs such as unfractionated heparin for acute treatment of VTE with more targeted approaches, predictable pharmacokinetic profiles and lack of need for monitoring. Vitamin K antagonists, with inherent limitations of multiple food and drug interactions and frequent need for monitoring, remain the only oral anticoagulants approved for long-term secondary thromboprophylaxis in VTE with the removal of the oral direct thrombin inhibitor ximelagatran from the world market due to safety concerns. Newer anticoagulant drugs such as parenteral pentasaccharides (idraparinux and SSR-126517-E), oral direct thrombin inhibitors (dabigatran), oral direct Factor Xa inhibitors (rivaroxaban, apixaban, YM-150 and DU-176b) and tissue factor-Factor VIIa complex inhibitors (NAPc2) are tailor-made to target specific procoagulant complexes and have the potential to greatly expand our antithrombotic armamentarium for both acute and long-term treatment of VTE, especially as non-monitored parenteral and oral anticoagulants with a wide therapeutic window and a predictable anticoagulant response.

    By ultrasound scanning it was determined that respiratory movements made by chest of healthy and sick person are accompanied by respiratory chest rise of internal jugular veins. During the exhalation of an individual diameter of his veins increases and during the breath it decreases down to the complete disappearing if their lumen. Change of the diameter of internal jugular veins in different phases can influence significantly the results of vein puncture and cauterization in patients. The purpose of this research is development of the method increasing the efficiency and safety of cannulation of internal jugular veins by the ultrasound visualization. We suggested the method of catheterization of internal jugular veins by the ultrasound navigation during the execution of which the puncture of venous wall by puncture needle and the following conduction of J-guide is carried out at the moment of patient’s exhalation. This method decreases the risk of complications development during catheterization of internal jugular vein due to exclusion of perforating wound of vein and subjacent tissues and anatomical structures.

  15. Lower limb ischaemia in patients with diabetic foot ulcers and gangrene: recognition, anatomic patterns and revascularization strategies.

    The confluence of several chronic conditions--in particular ageing, peripheral artery disease, diabetes, and chronic kidney disease--has created a global wave of lower limbs at risk for major amputation. While frequently asymptomatic or not lifestyle limiting, at least 1% of the population has peripheral artery disease of sufficient severity to be limb threatening. To avoid the critical error of failing to diagnose ischaemia, all patients with diabetic foot ulcers and gangrene should routinely undergo physiologic evaluation of foot perfusion. Ankle brachial index is useful when measurable, but may be falsely elevated or not obtainable in as many as 30% of patients with diabetic foot ulcers primarily because of medial calcinosis. Toe pressures and skin perfusion pressures are applicable to such patients. PMID:26455728

    Xanthogranulomatous pyelonephritis (XP) is a rare form of pyelonephritis and without treatment destructive to the kidney. We describe a 74-year-old Caucasian immunocompetent female patient with XP and multiple abscesses on the upper pole of the right kidney and several impacted obstructing renal calculi in the middle calyx that developed severe colitis and gangrenous appendicitis during therapy. Proteus mirabilis was detected as the major pathogen in the urine culture. Kidney preserving therapy was carried out by intensive parenteral bacterial eradication, CT-guided abscess drainage and stone destruction by 3 sessions of extracorporeal shock wave lithotripsy under ureteral stenting. Large tumor masses in XP are often daunting and may lead to a nephrectomy. However, kidney-preserving therapy is possible and should be considered in non-septic patients or in case of a solitary kidney. PMID:26889137

    Background: Proximal tibia fractures with compartment syndrome present a challenge for orthopedic surgeons. More often than not these patients are subjected to multiple surgeries and are complicated by infection osteomyelitis and poor rehabilitation. There is no consensus in the management of these fractures. Most common mode is to do early fasciotomy with external fixation, followed by second stage definitive fixation. We performed a retrospective study of proximal tibia fractures with impending compartment syndrome treated by single stage fasciotomy and internal fixation. Results in terms of early fracture union, minimum complications and early patient mobilization were very good. Materials and Methods: Fifteen patients who were operated between July 2011 and June 2012 were selected for the study. All documents from their admission until the last followup in December 2013 were reviewed, data regarding complications collected and results were evaluated using Oxford Knee scoring system. Results: At the final outcome, there was anatomical or near anatomical alignment with no postoperative problems with range of motion of near complete flexion (>120) in all patients within 3 months. 13 patients started full weight bearing walking at 3 months. Delayed union in two patients and skin necrosis in one patient was observed. Conclusions: Since the results are encouraging and the rehabilitation time is much less when compared to conventional approaches, it is recommended using this protocol to perform early fasciotomy with the definitive internal fixation as single stage surgery to obtain excellent followup results and to reduce rehabilitation time, secondary trauma, expense of treatment and infection rate.

  20. Venous waterfalls in coronary circulation.

    Several studies of flow through collapsible tubing deformed by external pressures have led to a concept known as the "vascular waterfall". One hallmark of this state is a positive zero-flow pressure intercept (Pe) in flow-pressure curves. This intercept is commonly observed in the coronary circulation, but in blood-perfused beating hearts a vascular waterfall is not the only putative cause. To restrict the possibilities, we have measured flow-pressure curves in excised non-beating rabbit hearts in which the coronary arteries were perfused in a non-pulsatile way with a newtonian fluid (Ringers solution) containing potent vasodilator drugs. Under these circumstances, vascular waterfalls are believed to be the only tenable explanation for Pe. In physical terms the waterfall is a region where the vessel is in a state of partial collapse with a stabilized intraluminal fluid pressure (Pw). It is argued that the most probable site of this collapse was the intramural veins just before they reached the epicardial surface. In accord with the waterfall hypothesis, Pe increased as the heart became more edematous, but flow-pressure curves also became flatter, implying multiple waterfalls with differing Pws, leading to complete collapse of some of the venous channels. The principal compressive force is believed to have been the interstitial fluid pressure as registered through a needle (Pn) implanted in the left ventricular wall, but a small additional force (Ps) was probably due to swelling of interstitial gels. A method is presented for estimating Ps and Pw. Unlike rubber tubing, blood vessels are both collapsible and porous. Apparently because of increased capillary filtration, Pn was found to increase linearly with the perfusion pressure. Thus, Pw was not the same at all points on the flow-pressure curve. This finding has interesting implications with respect to the concept of coronary resistance. PMID:2062096

    The metabolic rate and oxygen consumption of the brain is reflected in jugular venous oxygen saturation. In many clinical conditions, such as head trauma, stroke, and low cardiac output states, the brain is at risk for hypoxic-ischemic injury. The current gold standard for monitoring brain oxygenation is invasive and requires jugular vein catheterization under fluoroscopic guidance; and therefore it is rarely used. Photo-acoustic tomography in combination with ultrasound can be used to estimate oxygen saturation of the internal jugular vein in real-time. This noninvasive method will enable earlier detection and prevention of impending hypoxic brain injury. A wavelength-tunable dye laser pumped by a Nd:YAG laser delivers light through an optical fiber bundle, and a modified commercial ultrasound imaging system (Philips iU22) detects both the pulse-echo ultrasound (US) and photoacoustic (PA) signals. A custom-built multichannel data acquisition system renders co-registered ultrasound and photoacoustic images at 5 frames per second. After the jugular vein was localized in healthy volunteers, dualwavelength PA images were used to calculate the blood hemoglobin oxygen saturation from the internal jugular vein in vivo. The preliminary results raise confidence that this emerging technology can be used clinically as an accurate, noninvasive indicator of cerebral oxygenation.

    The aim of this review was to discuss the current knowledge on etiopathogenesis, diagnosis and therapeutic management of venous malformations. Venous malformations (VMs) are slow-flow vascular anomalies. They are simple, sporadic or familial (cutaneo-mucosal venous malformation or glomuvenous malformations), combined (e.g. capillaro-venous, capillaro-lymphaticovenous malformations) or syndromic (Klippel-Trenaunay, Blue Rubber Bleb Naevus and Maffucci). Genetic studies have identified causes of familial forms and of 40% of sporadic VMs. Another diagnostic advancement is the identification of elevated D-dimer level as the first biomarker of venous malformations within vascular anomalies. Those associated with pain are often responsive to Low Molecular Weight Heparin which should also be used to avoid disseminated intravascular coagulopathy secondary to intervention, especially if fibrinogen level is low. Finally, development of a modified sclerosing agent, ethylcellulose–ethanol, has improved therapy. It is efficient and safe, and widens indications for sclerotherapy to sensitive and dangerous areas such as hands, feet and periocular area. PMID:20870869

    Central venous catheterisation under two-dimensional ultrasound (US) guidance has been proved to be quicker and safer than the classical landmark method in both adults and children. In the literature US guidance with sterile dressing of the probe is the 'gold-standard'. Another way to use US is simple preoperative US location followed either by blind puncture, either by US guided puncture when difficulties are expected: small infants (<15 kg), small diameter or collapses of the vein, multiple unsuccessful attempts during blind technique. Ideal location of the tip of central venous catheters is no more controversial but can depend on age and weight. In 2002 a French agency (Afssaps) study showed that the risk of perforation and tamponade was especially high in small weight prematures with 27 gauge polyurethane catheters when tip was located in the cardiac cavities. In children and adults venous thrombosis and catheter malfunction are closely related to short catheters whose tip is above T3-T4. Excepted polyurethane catheters in small weight prematures, the best location of long-term central venous catheters tip is the superior vena cava-right auricle junction. At this time routine antithrombotic prophylaxis is not recommended for children with long-term central venous catheters. PMID:16414237

    Multiple factors contribute to the risk of venous thromboembolism (VTE). Platelets have attracted much interest in arterial cardiovascular disease, whereas their role in VTE has received much less attention. Recent evidence suggests that platelets may play a more important role in VTE than previously anticipated. This review discusses the mechanisms that link platelets with venous thrombotic disease and their potential applications as novel risk factors for VTE. In addition, animal studies and randomized clinical trials that highlight the potential effect of antiplatelet therapy in venous thrombosis are evaluated to assess the role of platelets in VTE. The clinical significance of platelets for VTE risk assessment in specific patient cohorts and their role as a suitable therapeutic target for VTE prevention is acknowledged. The role of platelets in VTE is a promising field for future research. PMID:26926584

    A technique for the noninvasive measurement of CVP in man was developed. The method involves monitoring venous velocity at a point in the periphery with a transcutaneous Doppler ultrasonic velocity meter while the patient performs a forced expiratory maneuver. The idea is the CVP is related to the value of pressure measured at the mouth which just stops the flow in the vein. Two improvements were made over the original procedure. First, the site of venous velocity measurement was shifted from a vein at the antecubital fossa (elbow) to the right external jugular vein in the neck. This allows for sensing more readily events occurring in the central veins. Secondly, and perhaps most significantly, a procedure for obtaining a curve of relative mean venous velocity vs mouth pressure was developed.

    Cerebral venous thrombosis is a rare disease characterized by its clinical polymorphism and multiplicity of risk factors. Infections represent less than 10% of etiologies. Tuberculosis is not a common etiology, only a few observations are published in the literature. Between January 2005 and March 2015, 61 patients were hospitalized for neuro-meningeal tuberculosis. Among them, three young women had presented one or more cerebral venous sinus thromboses. No clinical feature was observed in these patients; vascular localizations were varied: sagittal sinus (2 cases), lateral sinus (2 cases) and transverse sinus (1 case). With anticoagulant and antituberculosis drugs, the outcome was favorable in all cases. During neuro-meningeal tuberculosis, the existence of consciousness disorders or neurological focal signs is not always the translation of encephalitis, hydrocephalus, tuberculoma or ischemic stroke; cerebral venous sinus thrombosis may be the cause and therefore should be sought.

    Despite clear guidelines and the availability of effective treatments, venous thromboembolism (VTE) remains relatively common, particularly in the hospital setting. This paper reviews topical issues in VTE, in terms of treatments, data and guidelines. Existing anticoagulants have several limitations. Bleeding risk is a concern with all anticoagulants. Vitamin K antagonists are the mainstay of oral anticoagulant therapy, but they are limited by the need for frequent monitoring. Unfractionated heparin (UFH) is limited by an inconvenient route of administration (continuous intravenous infusion) and a higher risk of heparin-induced thrombocytopenia and bleeding compared with low molecular weight heparins (LMWH). LMWH have a more predictable pharmacokinetic profile and greater bioavailability than UFH, which permits weight-adjusted LMWH dosing without the need for monitoring in most patients. LMWH also have a more convenient dosing strategy than UFH (once-daily subcutaneous injection). Fondaparinux is a selective inhibitor of factor Xa and, like LMWH, does not require monitoring. The efficacy of fondaparinux in long-term VTE treatment remains to be established. The optimal time to initiate thromboprophylaxis in patients undergoing orthopaedic surgery remains controversial. Initiating thromboprophylaxis just before or soon after surgery (the 'just-in-time' strategy) achieves better thromboprophylaxis but could increase the risk of bleeding complications. Balancing the need for extended thromboprophylaxis after major surgery with the need to minimize bleeding remains an important consideration. Despite clear guidelines, thromboprophylaxis is widely underused, particularly in medical patients, in whom rates as low as 28% have been reported. Electronic alert systems may be of value for increasing the use of adequate thromboprophylaxis. The use of different definitions of VTE and bleeding in clinical trials, together with missing venography data, conflicting guidelines in

    Major wound complications of the extremities, following wide tumor resection and reconstruction for soft-tissue sarcomas (STSs), remain a challenge for limb-sparing surgery. Furthermore, STSs with ulceration or impending ulceration predispose patients to an increased risk of post-operative infection. The present study was conducted to assess the efficacy of negative pressure wound therapy (NPWT) in preventing wound complications associated with surgical treatment of STSs with ulceration or impending ulceration, in patients treated between February 2012 and January 2013. A total of 5 patients, with a mean age of 48 years (range, 24–68 years), were enrolled in the present study. The diagnoses consisted of undifferentiated pleomorphic sarcoma (n=2), leiomyosarcoma (n=1), synovial sarcoma (n=1) and epithelioid sarcoma (n=1). According to American Joint Committee on Cancer criteria, 3 cases were stage III tumors, and the remaining 2 cases were of stages IIA and IIB, respectively. A total of 3 patients exhibited ulceration at diagnosis, and the remaining patients demonstrated impending ulceration. The mean wound area following wide resection of the tumor was 73 cm2 (range, 45–110 cm2). A continuous suction mode, with pressures measuring −200 to −300 mmHg, was used for 7–10 days on the soft-tissue defects as preparation for wound closure. Soft-tissue reconstruction included muscle flaps (n=2) and skin grafts (n=5). No major wound complications occurred. Post-operative functional and cosmetic outcomes were acceptable. A single patient demonstrated local recurrence 12 months after surgery and re-excision of the tumor was performed. All patients remained alive at the conclusion of follow-up, with a mean follow-up time of 26 months (range, 12–36 months). The present study demonstrated that NPWT is effective and safe when used as an adjunct to wound closure following resection of extremity STS with ulceration/impending ulceration. PMID:27347212

    To study MR patterns of venous sinus occlusive disease and to relate them to the underlying pathophysiology by comparing the appearance and pathophysiologic features of venous sinus occlusive disease with those of arterial ischemic disease. The clinical data and MR examinations of 26 patients with venous sinus occlusive disease were retrospectively reviewed with special attention to mass effect, hemorrhage, and T2-weighted image abnormalities as well as to abnormal parenchymal, venous, or arterial enhancement after intravenous gadopentetate dimeglumine administration. Follow-up studies when available were evaluated for atrophy, infraction, chronic mass effect, and hemorrhage. Mass effect was present in 25 of 26 patients. Eleven of the 26 had mass effect without abnormal signal on T2-weighted images. Fifteen patients had abnormal signal on T2-weighted images, but this was much less extensive than the degree of brain swelling in all cases. No patient showed abnormal parenchymal or arterial enhancement. Abnormal venous enhancement was seen in 10 of 13 patients who had contrast-enhanced studies. Intraparenchymal hemorrhage was seen in nine patients with high signal on T2-weighted images predominantly peripheral to the hematoma in eight. Three overall MR patterns were observed in acute sinus thrombosis: (1) mass effect without associated abnormal signal on T2-weighted images, (2) mass effect with associated abnormal signal on T2-weighted images and/or ventricular dilatation that may be reversible, and (3) intraparenchymal hematoma with surrounding edema. MR findings of venus sinus occlusive disease are different from those of arterial ischemia and may reflect different underlying pathophysiology. In venous sinus occlusive disease, the breakdown of the blood-brain barrier (vasogenic edema and abnormal parenchymal enhancement) does not always occur, and brain swelling can persist up to 2 years with or without abnormal signal on T2-weighted images. 34 refs., 5 figs.

    The intracranial venous sinus is an important component of vascular disease. Many diseases involve the venous sinus and are accompanied by venous sinus stenosis (VSS), which leads to increased venous pressure and high intracranial pressure. Recent research has focused on stenting as a treatment for VSS related to these diseases. However, a systematic understanding of venous sinus stenting (VS-Stenting) is lacking. Herein, the literature on idiopathic intracranial hypertension (IIH), venous pulsatile tinnitus, sinus thrombosis, high draining venous pressure in dural arteriovenous fistula (AVF) and arteriovenous malformation (AVM), and tumor-caused VSS was reviewed and analyzed to summarize experiences with VS-Stenting as a treatment. The literature review showed that satisfactory therapeutic effects can be achieved through stent angioplasty. Thus, the present study suggests that selective stent release in the venous sinus can effectively treat these diseases and provide new possibilities for treating intracranial vascular disease.
