ABSTRACT
Rickettsial diseases cover a broad spectrum of illnesses. Scrub typhus is present worldwide, and Orientia tsutsugamushi is the causative agent of this chigger mite-borne infectious illness. Infections exhibit a range of severity, from mild illness to the more severe manifestation of multiorgan failure. We report three cases of scrub fever (55-year-old female, 63-year-old female, and 29-year-old male), all cases developed focal or pan-digital gangrene. All cases were successfully treated by administering doxycycline and additional supportive measures. Digital gangrene is uncommon in scrub typhus. Clinical suspension for early diagnosis and appropriate treatment may avoid further complications.

OBJECTIVE: This study aims to investigate the characteristics, risk factors, and outcomes of digital gangrenes in SSc patients, and to identify whether vasculitis is one of the causes for digital gangrene. METHODS: A retrospective case-control study was performed from February 2003 to April 2021. Forty-three SSc patients with digital gangrene admitted to Peking Union Medical College Hospital were included. One-hundred forty-six age- and sex-matched SSc patients without gangrene were selected as controls during the same period. Univariate and multivariate logistic regression analysis was used to determine risk factors. RESULTS: Among 43 SSc patients with gangrene, 93.0% had Raynaud's phenomenon (RP) and 32.6% had current or previous digital ulcers (DU). SSc patients with digital gangrene had more ESR elevation (54.8% vs. 34.9%, p = 0.020) and higher level of high-sensitive C reactive protein (median 7.2 mg/L vs. 1.8 mg/L, p = 0.045) compared with controls. In the multivariable logistic regression analysis, smoking history (OR 4.119, p = 0.037), anti-centromere antibody positivity (OR 3.542, p = 0.016), anti-neutrophil cytoplasmic antibody positivity (OR 22.605, p = 0.037), and anti-phospholipid antibody positivity (OR 16.563, p = 0.001), as well as elevated ESR (OR 2.524, p = 0.038) were identified as independent risk factors for gangrenes. Most (79.1%) cases were treated with combination of immunosuppressive and vasodilating therapy, and four cases also got remised after treatment of only glucocorticoid and immunosuppressive agent. CONCLUSION: Smoking history; positive-ACA, ANCA, and anti-phospholipid antibodies; and increased ESR were independent risk factors for digital gangrenes in SSc. Vasculitis and macrovascular disease may contribute to the progression of digital gangrenes. Key Points â¢18.6% of SSc patients with digital gangrene had macrovascular stenosis. â¢Smoking, positive-ACA, ANCA, aPL, and increased ESR were indicators for digital gangrenes in SSc. â¢Vasculitis and macrovascular disease may involve in the pathogenesis.

BACKGROUND: Ileo-ileal knotting is a very rare cause of small bowel obstruction, and only a few reports have been published. Small bowel obstruction (SBO) is one of the most common emergency surgical conditions that require urgent evaluation and treatment and is one of the leading causes of emergency surgical admission. There are many causes of SBO that are known in general surgical practice, and these causes are different in the developing and developed worlds. CLINICAL PRESENTATION: In this article, we present a case of acute gangrenous SBO secondary to ileo-ileal knotting in a 37-year-old Ethiopian female patient after she presented with severe abdominal cramp, vomiting, and abdominal distension of 4 hours duration. The patient was operated on intraoperatively; she had gangrenous small bowel obstruction caused by ileo-ileal knotting. Later, the patient was discharged and improved after 12 days of hospital stay. CONCLUSION: Ileo-ileal knotting should always be considered in the differential diagnosis of acute small-bowel obstruction. The diagnostic difficulty and the need for urgent treatment of this condition to yield optimal results are discussed.

BACKGROUND: Foot ulcers and/or infections are common long-term complications of diabetes and are associated with increased mortality, especially from cardiovascular disease, though only a few studies have investigated the independent contribution of these events to risk of death. This study aimed at assessing the association of history of diabetic foot with all-cause mortality in individuals with type 2 diabetes, independent of cardiovascular risk factors, other complications, and comorbidities. METHODS: This prospective cohort study enrolled 15,773 Caucasian patients in 19 Italian centers in the years 2006-2008. Prior lower extremity, coronary, and cerebrovascular events and major comorbidities were ascertained by medical records, diabetic retinopathy by fundoscopy, diabetic kidney disease by albuminuria and estimated glomerular filtration rate, cardiovascular risk factors by standard methods. All-cause mortality was retrieved for 15,656 patients on 31 October 2015. RESULTS: At baseline, 892 patients (5.7%) had a history of diabetic foot, including ulcer/gangrene and/or amputation (n = 565; 3.58%), with (n = 126; 0.80%) or without (n = 439; 2.78%) lower limb revascularization, and revascularization alone (n = 330; 2.09%). History of diabetic foot was associated with all-cause death over a 7.42-year follow-up (adjusted hazard ratio, 1.502 [95% confidence interval, 1.346-1.676], p < 0.0001), independent of confounders, among which age, male sex, smoking, hemoglobin A1c, current treatments, other complications, comorbidities and, inversely, physical activity level and total and HDL cholesterol were correlated independently with mortality. Both ulcer/gangrene and amputation alone were independently associated with death, with a higher strength of association for amputation than for ulcer/gangrene (1.874 [1.144-3.070], p = 0.013 vs. 1.567 [1.353-1.814], p < 0.0001). Both ulcer/gangrene/amputation and lower limb revascularization alone were independently associated with death; mortality risk was much higher for ulcer/gangrene/amputation than for revascularization (1.641 [1.420-1.895], p < 0.0001 vs. 1.229 [1.024-1.475], p = 0.018) and further increased only slightly for combined ulcer/gangrene/amputation and revascularization (1.733 [1.368-2.196], p < 0.0001). CONCLUSIONS: In patients with type 2 diabetes, an history of diabetic foot event, including ulcer/gangrene, amputation, and lower limb revascularization, was associated with a ~ 50% increased risk of subsequent death, independent of cardiovascular risk factors, other complications and severe comorbidities, which were also significantly associated with mortality. The association with mortality was greatest for amputation, whereas that for revascularization alone was relatively modest. TRIAL REGISTRATION: ClinicalTrials.gov, NCT00715481, retrospectively registered 15 July, 2008.

To explore the clinical characteristics of systemic sclerosis complicated with silicosis. The systemic sclerosis patients treated in the Guangxi Workers' Hospital and the People's Hospital of Guangxi Zhuang Autonomous Region from January 2000 to December 2020 were divided into the systemic sclerosis with silicosis group and the systemic sclerosis without silicosis group. Survival analysis was performed using Kaplan-Meier estimates the Cox proportional hazards model. A propensity score matching was applied in order to avoid the selection bias.Over the past 20 years, 72 systemic sclerosis patients with silicosis and 238 systemic sclerosis patients without silicosis were treated in the two hospitals. The systemic sclerosis patients with silicosis group had more males (P < 0.000),lower mean age at onset of SSc (P < 0.000), more frequent occurrence of weight loss (P = 0.028), smoking (P < 0.000), tuberculosis (P < 0.000), cardiac involvement (P < 0.000), ILD (P = 0.017), pulmonary hypertension (P = 0.024), elevated BNP (P < 0.000). With regards to the multivariate Cox regression analysis, silicosis was related with a higher overall mortality before (HR = 3.666, 95% CI = 1.440-11.234, p = 0.025) and after the propensity score matching analysis (HR = 2.817, 95% CI = 1.196-10.764, p = 0.014). Independent risk factors for overall mortality were Gangrene (HR = 3.003, 95% CI = 1.343-9.431), Cardiac involved (HR = 5.370, 95% CI = 1.910-15.472), Scl-70 (HR = 3.569, 95% CI = 1.333-10.869), Elevated BNP (HR = 2.135, 95% CI = 1.293-9.564).Concomitant silicosis worsens systemic sclerosis patients' prognoses. Gangrene, Scl-70, elevated BNP and cardiac involvement are independent risk factors for overall mortality. Key Points â¢Concomitant silicosis worsens SSc patients' prognoses. â¢For individuals with occupational exposure, close observation of the symptoms of SSc, early diagnosis, and interruption of exposure may improve the prognosis. â¢Gangrene, Scl-70, elevated BNP and cardiac involvement are independent risk factors for overall mortality.

INTRODUCTION: Peripheral artery disease (PAD) is associated with an increased likelihood of delayed or non-healing of a diabetes-related foot ulcer, gangrene, and amputation. The selection of the most effective surgical technique for revascularisation of the lower limb in this population is challenging and there is a lack of conclusive evidence to support the choice of intervention. This systematic review aimed to determine, in people with diabetes and tissue loss, if direct revascularisation is superior to indirect revascularisation and if endovascular revascularisation is superior to open revascularisation for the outcomes of wound healing, minor or major amputation, and adverse events including mortality. METHODS: Title and abstract searches of Medline, Embase, PubMed, and EBSCO were conducted from 1980 to 30th November 2022. Cohort and case-control studies and randomised controlled trials reporting comparative outcomes of direct (angiosome) revascularisation (DR) and indirect revascularisation (IR) or the comparative outcomes of endovascular revascularisation and open or hybrid revascularisation for the outcomes of healing, minor amputation, and major amputation in people with diabetes, PAD and tissue loss (including foot ulcer and/or gangrene) were eligible. Methodological quality was assessed using the Cochrane risk-of-bias tool for randomised trials, the ROBINS-I tool for non-randomised studies, and Newcastle-Ottawa Scale for observational and cohort studies where details regarding the allocation to intervention groups were not provided. RESULTS: From a total 7086 abstracts retrieved, 26 studies met the inclusion criteria for the comparison of direct angiosome revascularisation (DR) and indirect revascularisation (IR), and 11 studies met the inclusion criteria for the comparison of endovascular and open revascularisation. One study was included in both comparisons. Of the included studies, 35 were observational (31 retrospective and 4 prospective cohorts) and 1 was a randomised controlled trial. Cohort study quality was variable and generally low, with common sources of bias related to heterogeneous participant populations and interventions and lack of reporting of or adjusting for confounding factors. The randomised controlled trial had a low risk of bias. For studies of DR and IR, results were variable, and it is uncertain if one technique is superior to the other for healing, prevention of minor or major amputation, or mortality. However, the majority of studies reported that a greater proportion of participants receiving DR healed compared with IR, and that IR with collaterals may have similar outcomes to DR for wound healing. For patients with diabetes, infrainguinal PAD, and an adequate great saphenous vein available for use as a bypass conduit who were deemed suitable for either surgical procedure, an open revascularisation first approach was superior to endovascular therapy to prevent a major adverse limb event or death (Hazard Ratio: 0.72; 95% CI 0.61-0.86). For other studies of open and endovascular approaches, there was generally no difference in outcomes between the interventions. CONCLUSIONS: The majority of available evidence for the effectiveness of DR and IR and open and endovascular revascularisation for wound healing and prevention of minor and major amputation and adverse events including mortality in people with diabetes, PAD and tissue loss is inconclusive, and the certainty of evidence is very low. Data from one high quality randomised controlled trial supports the use of open over endovascular revascularisation to prevent a major limb event and death in people with diabetes, infrainguinal disease and tissue loss who have an adequate great saphenous vein available and who are deemed suitable for either approach.

OBJECTIVE: Specialty care may improve diabetic foot ulcer outcomes. Medically underserved populations receive less specialty care. We aimed to determine the association between specialty care and ulcer progression, major amputation, or death. If a beneficial association is found, increasing access to specialty care might help advance health equity. RESEARCH DESIGN AND METHODS: We retrospectively analyzed a cohort of Wisconsin and Illinois Medicare patients with diabetic foot ulcers (n = 55,409), stratified by ulcer severity (i.e., early stage, osteomyelitis, or gangrene). Within each stratum, we constructed Kaplan-Meier curves for event-free survival, defining events as: ulcer progression, major amputation, or death. Patients were grouped based on whether they received specialty care from at least one of six disciplines: endocrinology, infectious disease, orthopedic surgery, plastic surgery, podiatry, and vascular surgery. Multivariate Cox proportional hazard models estimated the association between specialty care and event-free survival, adjusting for sociodemographic factors and comorbidities, and stratifying on ulcer severity. RESULTS: Patients who received specialty care had longer event-free survival compared to those who did not (log-rank p<0.001 for all ulcer severity strata). After adjusting, receipt of specialty care, compared to never, remained associated with improved outcomes for all ulcer severities (early stage adjusted hazard ratio 0.34, 95% CI 0.33-0.35, p<0.001; osteomyelitis aHR 0.22, 95% CI 0.20-0.23, p<0.001; gangrene aHR 0.22, 95% CI 0.20-0.24, p<0.001). CONCLUSIONS: Specialty care was associated with longer event-free survivals for patients with diabetic foot ulcers. Increased, equitable access to specialty care might improve diabetic foot ulcer outcomes and disparities.

PURPOSE: Distinguishing between perforated/gangrenous from uncomplicated appendicitis in children helps management. We evaluated hyponatremia as a new diagnostic marker for perforated/gangrenous appendicitis in children. METHODS: A prospective study including all children with acute appendicitis who underwent appendectomy at our institution from May 2021 to May 2023. Medical history and clinical criteria were analyzed. All blood samples were taken upon admission including serum inflammatory markers and electrolytes. Patients were divided into two groups (Group I: uncomplicated and Group II: perforated/gangrenous), and data between both groups were compared. RESULTS: The study included 153 patients [Group I: 111 (73%), Group II: 42 (27%)]. Mean serum sodium concentration in children with perforated/gangrenous appendicitis was significantly lower compared to children with uncomplicated appendicitis (131.8 mmol/L vs. 138.7 mmol/L; p < 0.001). The ROC curve of preoperative sodium level to differentiate between perforated/gangrenous and uncomplicated appendicitis revealed an AUC of 0.981. The cut-off-value of sodium level < 135 mmol/L identified perforated/gangrenous appendicitis with a sensitivity of 94% and a specificity of 91% (p < 0.001). Predictive factors of perforated/gangrenous appendicitis were: age less than 5 years (12% vs. 3%; p = 0.02), experiencing symptoms for more than 24 h (100% vs. 58%; p < 0.001), body temperature more than 38.5 °C (52% vs. 13%; p < 0.001), a serum sodium level less than 135 mmol/L (90% vs. 6%; p < 0.001), and a CRP serum level more than 50 mg/L (71% vs. 17%; p < 0.001). CONCLUSIONS: Hyponatremia, upon admission, is a novel, objective biochemical marker that can identify perforated/gangrenous appendicitis in children. We advocate that the assessment of serum sodium level should be added to the diagnostic algorithm in children with suspected acute appendicitis. Surgical intervention in patients with hyponatremia should not be delayed, and non-operative management should be avoided.

Heparin-induced thrombocytopenia (HIT) is a prothrombotic state caused by the buildup of platelet factor 4 antibodies with decreased platelet count caused by heparin therapeutic or prophylactic therapy. It is important to detect this complication, especially in critically ill patients and cardiac patients. Detection of HIT can be demonstrated by positive antibodies in a HIT panel. Based on clinical and laboratory findings, heparin use should be discontinued with immediate transition to alternative anticoagulation therapies. Thromboembolic events can be an adverse effect of HIT and can cause local tissue necrosis, especially in the lower extremity. This case is a retrospective medical record review of a 52-year-old man who was initially admitted as an outpatient for coronary artery bypass grafting and mitral valve replacement who developed digital gangrene from HIT. This case emphasizes the rare adverse effects of HIT and the need for timely consultation for surgical treatment of limb ischemia/gangrene.

Objectives: To analyze clinical characteristics of the diabetic inpatients with foot ulcers and explore the risk factors of lower extremity amputation (LEA) in West China Hospital of Sichuan University. Methods: A retrospective analysis was performed based on the clinical data of the patients with diabetic foot ulcer (DFU) hospitalized in West China Hospital of Sichuan University from January 1, 2012 to December 31, 2020. The DFU patients were divided into three groups: non-amputation, minor amputation, and major amputation groups. The ordinal logistic regression analysis was used to identify the risk factors for LEA. Results: 992 diabetic patients (622 males and 370 females) with DFU were hospitalized in the Diabetic Foot Care Center of Sichuan University. Among them, 72 (7.3%) (55 minor amputations and 17 major amputations) cases experienced amputation, and 21(2.1%) refused amputation. Excluding the patients who refused amputation, the mean age and duration of diabetes of and HbA1c the 971 patients with DFU, were 65.1 ± 12.3 years old, 11.1 ± 7.6 years, and 8.6 ± 2.3% respectively. The patients in the major amputation group were older and had longer course of diabetes for a longer period of time than those in the non-amputation and minor amputation groups. Compared with the non-amputation patients (55.1%), more patients with amputation (minor amputation (63.5%) and major amputation (88.2%)) suffered from peripheral arterial disease (P=0.019). The amputated patients had statistically lower hemoglobin, serum albumin and ankle brachial index (ABI), but higher white blood cell, platelet counts, fibrinogen and C-reactive protein levels. The patients with amputation had a higher incidence of osteomyelitis (P = 0.006), foot gangrene (P < 0.001), and a history of prior amputations (P < 0.001) than those without amputation. Furthermore, a history of prior amputation (odds ratio 10.194; 95% CI, 2.646-39.279; P=0.001), foot gangrene (odds ratio 6.466; 95% CI, 1.576-26.539; P=0.010) and ABI (odds ratio 0.791; 95% CI, 0.639-0.980; P = 0.032) were significantly associated with LEAs. Conclusions: The DFU inpatients with amputation were older with long duration of diabetes, poorly glycemic control, malnutrition, PAD, severe foot ulcers with infection. A history of prior amputation, foot gangrene and a low ABI level were the independent predictors of LEA. Multidisciplinary intervention for DFU is essential to avoid amputation of the diabetic patients with foot ulcer.

INTRODUCTION: External genitalia gangrene is a well-known uncommon disease; however, mortality remains important. Recent literature focuses on early management. The object of this study was to assess quality of life and disease-specific function, in the medium- and long-term. METHOD: We evaluated retrospectively adult inpatients with external genitalia gangrene who had a surgical debridement between 2010 and 2020 at CHU de Poitiers. Preoperatory FGSI Score was calculated for patients included. In a second phase, surviving patients at 2020 who had agreed to take part in the follow-up were assessed by clinical examination, and asked to complete Short-Form 36 test and two additional disease-specific questionnaire (USP, IIEF5). RESULTS: The patients consisted of 33 men. Mean age was 61.18. Eleven patients (33%) died primarily from external genitalia gangrene. Median FGSI score was 6 (1-13). We were able to reach 11 patients (33%) for secondary clinical revaluation. Time before revaluation was 3months to 8years. All parts of SF-36 were significantly low. Mean USP score was 1.27±2.68/4.54±4.43/0.72±1.84. Nine patients (81%) suffered erectile dysfunction without any sexual intercourse possible. CONCLUSION: Patients with external genitalia gangrene experience severe deterioration of their quality of life. Multidisciplinary healthcare process should systematically be carried out, as so as early screening of vulnerability risks factors, to improve functional outcomes and quality of life.

BACKGROUND: Sigmoid volvulus is a pathology that can be mortal because it is frequently encountered in elderly patients. In case of bowel gangrene, mortality and morbidity increase further. We planned a retrospective study, in which the effectiveness of the model was evaluated by creating a model that aims to predict whether intestinal gangrene is present in patients with sigmoid volvulus only by blood tests and thus to quickly guide treatment methods. METHODS: In addition to demographic data such as age and gender, laboratory values such as white blood cell, C-reactive protein (CRP), lactate dehydrogenase (LDH), potassium, and colonoscopic findings and whether there was gangrene in the colon during the operation were evaluated retrospectively. In the analysis of the data, independent risk factors were determined by univariate and multivariate logistic regression analyzes as well as Mann-Whitney U and Chi-square tests. Receiver operating characteristic (ROC) analysis was performed for statistically significant continuous numerical data, and cutoff values were determined and Malatya Volvulus Gangrene Model (MVGM) was created. The effectiveness of the created model was again evaluated by ROC analysis. RESULTS: Of the 74 patients included in the study, 59 (79.7%) were male. The median age of the population was 74 (19-88), and gangrene was detected in 21 (28.37%) patients at surgery. In univariate analyzes, leukocytes <4000/mm3 and >12000/mm3 (OR: 10.737; CI 95%: 2.797-41.211, p=0.001), CRP ≥0.71 mg/dl (OR: 8.107 CI 95%: 2.520-26.082, p<0.0001), potassium ≥3.85 mmoL/L (OR: 3.889; 95% CI): 1.333-11.345, p=0.013), and LDH ≥288 U/L (OR: 3.889; CI 95%: 1.333-11.345, p=0.013), whereas, in multivariate analyzes, only CRP ≥0.71 mg/dL (OR: 3.965; CI 95%: 1.071-15.462, p=0.047) was found to be an independent risk factor for bowel gangrene. The strength of MVGM was AUC 0.836 (0.737-0.936). In addition, it was observed that the probability of bowel gangrene increased approximately 10 times if MVGM was ≥7 (OR: 9.846; 95% CI: 3.016-32.145, p<0.0001). CONCLUSION: Besides being non-invasive compared to the colonoscopic procedure, MVGM is a useful method for detecting bowel gangrene. In addition, it will guide the clinician in taking the patients with intestinal loop gangrene to emergency surgery without wasting time in the treatment steps, as well as avoiding complications that may occur during colonoscopy. In this way, we think that morbidity and mortality rates can be reduced.

BACKGROUND: Fournier's gangrene is a rare, fulminant, and usually localized necrotizing soft tissue polymicrobial infection of the perineum, with occasional extension up to the abdominal wall. CASE PRESENTATION: We describe an unusual case of penile gangrene in a 64-year-old Tunisian man suffering from urinary incontinence secondary to cerebrovascular accident. Gangrene developed due to continuous tourniquet effect on the penis caused by a condom catheter. Although source control was achieved with aggressive debridement, careful wound care, and wide-spectrum antibiotherapy, the patient died due to septic shock. CONCLUSION: Use of condom catheters is not without complications. Careful placement, strict hygiene, and regular monitoring of the local condition are necessary.

BACKGROUND: Many patients with polyarteritis nodosa (PAN) complicated by digital gangrene have poor outcomes and related research information is limited. Our aim is to identify the associated risk and prognostic factors in PAN patients with digital gangrene. PATIENTS AND METHODS: We conducted a retrospective study of 148 PAN patients admitted to Peking Union Medical College Hospital from Octorber 2001 to December 2018. Forty-seven (31.8%) PAN patients had digital gangrene. The average age was 40.4 ± 17.9 years. RESULTS: The presence of digital gangrene was correlated with current smoking (P = .008, odds ratio [OR] 2.99, 95% CI, 1.33-6.73), eosinophil elevation (P = .003, OR 4.21, 95% CI, 1.62-10.91) and elevated leukocytes (P = .001, OR 4.26, 95% CI, 1.86-9.78). Thirty-two (68.1%) gangrene patients received methylprednisolone pulse therapy and all of these patients were treated with cyclophosphamide. Nine patients suffered irreversible organ injury and 2 died. Survival analysis showed higher serum C-reactive protein (CRP) was associated with poor prognosis in patients with gangrene (log-rank P = 0.042 and generalized Wilcoxon P = .020). CONCLUSIONS: PAN patients with current smoking and eosinophil elevation were more prone to digital gangrene and a high serum CRP level predicted poor outcomes. The CRP level should be efficiently controlled to ensure a good prognosis.

The article is devoted to one of the rare forms of necrotizing fasciitis - Fourniers gangrene (FG). In chronological order, key aspects related to epidemiology, etiology, pathogenesis, classification, clinic, diagnosis and treatment are highlighted, according to extensive literature. It is postulated that according to modern scientific provisions, Fournier gangrene is a private clinical model of critical conditions in surgery, which is characterized by progressive purulent-necrotic lesion and putrefactive decay of soft tissue and fascial structures and is accompanied by phenomena of systemic endotoxicosis (sepsis) and high mortality, varying from 35 to 76-86%. It is declared that the trigger pathogenetic mechanism of the development of FG is disseminated thrombosis of the microcirculatory bed of the superficial fascia of the scrotum due to intravascular invasion of various strains of causative microbes. The methods of clinical, laboratory and instrumental diagnostics and methods of treatment are described, taking into account modern achievements of evidence-based medicine. Based on a multifactorial analysis of literature data and their own experience, the authors stated that the cornerstone that completely affects the outcome of treatment and prognosis of the disease is a multidisciplinary approach to solving diagnostic and therapeutic and tactical tasks with the participation of doctors of related specialties (surgeon, resuscitator, radiologist, cardiologist, coloproctologist, urologist, microbiologist). It is shown that the unshakable priority of treating patients with FG is still urgent surgical intervention in the format of "aggressive surgery", which provides for extremely wide excision of necrotic and non-viable tissues, followed by programmed (stage-by-stage) rehabilitation necrectomy.

BACKGROUND: Peripheral gangrene is rarely documented as a possible complication of Kawasaki disease (KD). There are many causes of peripheral gangrene, and the common cause is in situ thrombosis or embolism. Most cases are reported to have regrettable outcomes (amputation or necrotic shedding). Herein, we report the successful management of KD complicated by peripheral artery thrombosis in an older Chinese boy, and a review of all cases of peripheral gangrene in KD in the literature. CASE PRESENTATION: We found that most of the children with this complication were under 1 year old, had a heavy inflammatory response combined with the use of cortisol and immunoglobulin, and most children had coronary artery lesions. In addition, Peripheral gangrene mainly occurred in the subacute or chronic stage, and the prognosis is poor. CONCLUSIONS: In the presence of high risk factors, we consider it is necessary to monitor coagulation function and administer prophylactic anticoagulation therapy. When peripheral artery thrombosis or embolism occur, heparin and prostaglandins can be used for treatment.

Epidemiology, clinical presentation, and outcomes for digital gangrene in connective tissue disorders (CTD) remain underreported from tropical countries like India. In this series, we aimed to explore the clinical profile and outcomes of patients who presented with digital gangrene and a diagnosis of CTD. Hospital-based longitudinal observational study. Patients with digital gangrene and underlying diagnosis of CTD presenting to our tertiary-care centre in Jodhpur, India between1st January 2018 and 31st June 2021 were included. Clinical outcomes including mortality, limb outcomes, functional status and other systemic involvement were assessed. Of the 312 patients registered in the rheumatology clinic during this period, 22 (7%) patients were found to satisfy the inclusion criteria. Mean age was 46 years and 90% were females. The most common underlying diagnosis was Mixed connective tissue disorder (MCTD). Digital gangrene was the presenting symptom in 13 (60%) patients. Half of the patients received only corticosteroids as immunosuppression. Two died due to systemic complications. Complete resolution occurred in 17 (85%), autoamputation in 3, and infection requiring surgical drainage in one patient. All surviving patients reported good functional limb outcome on 6 months follow-up. MCTD is an important cause of digital gangrene in rheumatology practice. In patients presenting with digital gangrene, an active search for an underlying CTD is imperative, as this could result in timely initiation of appropriate limb-saving therapy. Corticosteroids alone with rapid tapering may be an appropriate option to consider in the initial management of digital gangrene in CTD. Key Points ⢠Mixed connective tissue disorder is an important cause of digital gangrene in rheumatology practice in western India. ⢠In patients presenting with digital gangrene, an active search for an underlying connective tissue disorder is imperative, as this could result in timely initiation of appropriate therapy and can prove limb saving. ⢠Corticosteroids alone with rapid tapering may be an appropriate option to consider in the initial management of digital gangrene in connective tissue disorders.

Importance: The clinical significance of gangrenous, suppurative, or exudative (GSE) findings is poorly characterized in children with nonperforated appendicitis. Objective: To evaluate whether GSE findings in children with nonperforated appendicitis are associated with increased risk of surgical site infections and resource utilization. Design, Setting, and Participants: This multicenter cohort study used data from the Appendectomy Targeted Database of the American College of Surgeons Pediatric National Surgical Quality Improvement Program, which were augmented with operative report data obtained by supplemental medical record review. Data were obtained from 15 hospitals participating in the Eastern Pediatric Surgery Network (EPSN) research consortium. The study cohort comprised children (aged ≤18 years) with nonperforated appendicitis who underwent appendectomy from July 1, 2015, to June 30, 2020. Exposures: The presence of GSE findings was established through standardized, keyword-based audits of operative reports by EPSN surgeons. Interrater agreement for the presence or absence of GSE findings was evaluated in a random sample of 900 operative reports. Main Outcomes and Measures: The primary outcome was 30-day postoperative surgical site infections (incisional and organ space infections). Secondary outcomes included rates of hospital revisits, postoperative abdominal imaging, and postoperative length of stay. Multivariable mixed-effects regression was used to adjust measures of association for patient characteristics and clustering within hospitals. Results: Among 6133 children with nonperforated appendicitis, 867 (14.1%) had GSE findings identified from operative report review (hospital range, 4.2%-30.2%; P < .001). Reviewers agreed on presence or absence of GSE findings in 93.3% of cases (weighted κ, 0.89; 95% CI, 0.86-0.92). In multivariable analysis, GSE findings were associated with increased odds of any surgical site infection (4.3% vs 2.2%; odds ratio [OR], 1.91; 95% CI, 1.35-2.71; P < .001), organ space infection (2.8% vs 1.1%; OR, 2.18; 95% CI, 1.30-3.67; P = .003), postoperative imaging (5.8% vs 3.7%; OR, 1.70; 95% CI, 1.23-2.36; P = .002), and prolonged mean postoperative length of stay (1.6 vs 0.9 days; rate ratio, 1.43; 95% CI, 1.32-1.54; P < .001). Conclusions and Relevance: In children with nonperforated appendicitis, findings of gangrene, suppuration, or exudate are associated with increased surgical site infections and resource utilization. Further investigation is needed to establish the role and duration of postoperative antibiotics and inpatient management to optimize outcomes in this cohort of children.

Coronary artery bypass grafting (CABG) is the most common surgery performed by cardiothoracic surgeons worldwide. Risks of CABG include neurological outcomes, deep vein thrombosis, renal or gastrointestinal injury, and death. Perioperatively, some patients may need intra-aortic balloon pump (IABP) use to help assist with cardiac function. In this case, a 75-year-old man presented with multivessel myocardial infarction requiring IABP for cardiac assistance prior to undergoing CABG. Eighteen days after his CABG, his toes turned black at home. A CT angiogram showed aortic atherosclerosis, right tibioperoneal trunk stenosis, mild atherosclerotic right proximal anterior tibial artery stenosis, and multifocal occlusive lesions in the right and left infrapopliteal vessels. Vascular surgery performed balloon angioplasty of the right anterior tibial artery and podiatry performed a transmetatarsal amputation of the dry gangrene. The aim of this case report is to present a rare complication of CABG with peri-operative IABP use and to highlight the need for prompt diagnosis and treatment of dry gangrene.
