Purpose: This study was conducted to determine the risk factors of major lower extremity amputations in type 2 diabetic patients referred for hospital care with diabetic foot syndrome. Patients and methods: This retrospective study involved 225 type 2 diabetic patients referred for management of diabetic foot syndrome at King Abdullah University Hospital in the period between January 2014 and December 2015. A structured customized diabetic foot data collection form with diabetic foot characteristics chart was used for documentation of relevant information, which checks for age, sex, body mass index, smoking, duration of diabetes, diabetic control therapy, associated hypertension, cardiac diseases, stroke, chronic renal impairment, renal replacement therapy (hem-dialysis), and history of diabetes-related complication in both feet prior to the study period. The predictors for major lower limb amputations were compared between groups using chi-square test, and binary logistic regression was used to determine the factors associated with major amputation. Results: Twenty-seven limbs underwent major amputations with an overall rate of major amputation of 11.6%. The following predictors were found to be associated with the higher incidence of major lower limb amputations: duration of diabetes ≥15 years, HbA1c ≥8%, patients on insulin, with hypertension, cardiac diseases, chronic renal impairment, stroke, having gangrene, higher number of components, higher Wagner classification, and ischemia. However, the rate did not differ significantly between men and women. Conclusion: Presentation with gangrenous tissue and poor glycemic control are the important risks and significant predictive factors for type 2 diabetes-related major lower limb amputations.

Purpose: Little is known about the existence of potential gender disparities in peripheral arterial occlusive disease. To our knowledge, this is the first study to analyze differences attributed to gender in type-2 diabetic patients with symptomatic peripheral arterial occlusive disease, with regard to clinical presentations, risk factors and anatomical distributions of atherosclerosis. Patients and methods: This study was conducted at King Abdullah University Hospital, Jordan. Medical records of all diabetic (type-2) patients who presented with symptomatic peripheral arterial occlusive disease in the period from January 2012 and November 2017 were reviewed, data were collected retrospectively. In all, 364 patients (282 males and 82 females) were involved. Criteria for diagnosis include the following Ankle-Brachial Index ⩽ 0.9 and intermittent claudication or critical limb ischemia. Risk factors for atherosclerosis (age, smoking and hypertension) and computed tomography-angiogram findings were analyzed using Statistical Package for the Social Sciences. p < 0.05 was considered statistically significant. Results: The mean age was higher in females than males (67.61 vs 62.61 years; p = 0.001). Females had greater prevalence of uncontrolled diabetes compared to males (HbA1c 9.07 in females vs 8.51 in males; p = 0.03). High density lipoprotein was higher in females than males (1.02 vs 0.935; p = 0.009). Females presented more with critical limb ischemia than intermittent claudication in comparison with males (p = 0.017). Involvement of superficial femoral artery, deep femoral artery and peroneal artery in hemodynamic relevant atherosclerotic lesion was significantly higher in females than males (p < 0.05). However, involvement of common iliac artery with hemodynamic relevant atherosclerotic lesion was significantly higher in males than females (p = 0.003). Conclusions: Clinical presentation, risk factors and anatomical distributions of atherosclerosis among type-2 diabetic patients with symptomatic peripheral arterial occlusive disease are different between males and females. When compared to males, female patients presented more with critical limb ischemia than intermittent claudication. Females showed higher age at presentation, poor control of diabetes mellitus and higher level of high density lipoprotein. Involvement of superficial femoral artery, deep femoral artery and peroneal artery in hemodynamic relevant atherosclerotic lesion were significantly higher in females than males. In contrast, common iliac artery involvement with hemodynamic relevant atherosclerotic lesion was significantly higher in males than females.

Background: Femoral pseudoaneurysm is the most important access site complication following cardiac catheterization. Ultrasound-guided compression repair is a safe and effective therapeutic modality with variable failure rates and risk factors. The aim of this study was to investigate which factors were associated with a higher incidence of ultrasound-guided compression repair failure for post-cardiac catheterization femoral pseudoaneurysm. Methods: Data were retrospectively collected from medical records at King Abdullah University Hospital during the period from January 2011 to December 2016. A total of 42 patients with post-cardiac catheterization femoral pseudoaneurysm had attempted ultrasound-guided compression repair. Data regarding patients, procedure and aneurysm-related factors were evaluated by univariate analysis and multivariate logistic regression. Results: Ultrasound-guided compression repair failed in 31% of the patients. Patients with body mass index of ⩾28 kg/m2, platelet count of ⩽180,000/L, time lag (age of aneurysm) of >48 h following puncture time, aneurysmal neck diameter of ⩾4 mm and communicating tract length of 48 h (odds ratio = 5.7), body mass index ⩾ 28 kg/m2 (odds ratio = 7.8), neck diameter > 4 mm (odds ratio = 14.4) and tract length < 8 mm (odds ratio = 18.6) were significantly associated with ultrasound-guided compression repair failure. Conclusion: Ultrasound-guided compression repair for patients with post-cardiac catheterization femoral pseudoaneurysm was successful in 69% of the patients. Risk factors for failed ultrasound-guided compression repair were as follows: delayed ultrasound-guided compression repair of >48 h, body mass index ⩾ 28 kg/m2, wide neck diameter > 4 mm and short aneurysmal communication tract < 8 mm.

Purpose: The aim of this study was to present the redefined clinical spectra of diabetic foot syndrome (RCS-DFS) and determine whether the RCS-DFS can be used to predict amputations. Patients and methods: This is a retrospective study of type 2 diabetic patients referred with DFS for management at King Abdullah University Hospital (KAUH) between January 2014 and December 2015. Data collection form and diabetic foot (DF) characteristic chart were used to document the following: demographic data, diabetes-related parameters, DF characteristics, surgical interventions and amputations. The predominant clinical presentations of DF problems (ulcer, sepsis or gangrene) were integrated with the clinical criteria for diabetic foot infection (DFI) diagnosis and classification of Infectious Diseases Association of America (IDSA)/International Working Group on Diabetic Foot (IWGDF) to redefine the clinical spectra of DFS. Related risk characteristics and amputation rate at all levels were compared between the three RCS. Results: In this study, there were 95 (47.0%) septic DFS (SDFS) patients, 65 (32.2%) ulcerative DFS (UDFS) patients and 42 (20.8%) gangrenous DFS (GDFS) patients. Poor glycemic control (HbA1c >7.5%), hypertension, history of the same foot problems, duration of symptoms, revascularizations and ischemic severity were significantly different between the three RCS. UDFS had the highest rate of limb salvage without amputations (70.8%). GDFS had the highest rate for final toe amputations (52.4%) and major amputations (23.8%). Final minor amputation rate was around 20% for both SDFS and GDFS. Conclusion: Redefining DFS into ulcerative, septic and gangrenous by integration of the predominant clinical presentation and the clinical criteria for DFI diagnosis and classification of IDSA/IWGDF showed significant differences in amputation rate. Therefore, it can be used clinically to categorize patients with DFS to predict amputations and to help in planning their management. Further prospective studies are suggested to validate these results.

Aims: Increased level of glycated hemoglobin (HbA1c) is associated with an increased prevalence of peripheral arterial disease (PAD). This study aimed to assess the relationship between the anatomical distribution of symptomatic PAD lesions in patients with type 2 diabetes and HbA1c levels at the time of PAD diagnosis. Patients and methods: A retrospective study was conducted at King Abdullah University Hospital during the period August 2011 to December 2015. Consecutive patients with type 2 diabetes presented with symptomatic PAD confirmed by computed tomography-angiography (CTA) were included in this study. CTA images were reviewed. Relevant information including demographic data, PAD symptoms, comorbidities, HbA1c level, lipid profile, C-reactive protein and the mean platelets volume were retrieved from medical records. Results: A total of 332 patients with type 2 diabetes (255 males and 77 females) were included in this study. The mean HbA1c at the time of PAD diagnosis was 8.68% (±2.06%). The prevalence of hemodynamic relevant atherosclerotic lesions of the superficial femoral artery, popliteal artery, leg vessels, femoro-popliteal, and crural segments was significantly higher in patients with HbA1c >7.5% compared with patients with HbA1c ⩽7.5%. Conclusion: The anatomical distribution of symptomatic PAD in patients with type 2 diabetes mellitus differed significantly according to HbA1c level at the time of PAD diagnosis.

Sacrococcygealteratoma is very rare in adults with only few cases reported in literature. It is a slow growing benign cystic tumor with 1-2% chance for malignant transformation and may attain a huge size causing pressure effect on pelvic and intra-abdominal organs. When grows caudally, it causes discomfort, skin excoriation and cosmetic disfigurement. We present a giant, long standing Sacrococcygeal teratoma in an adult female patient which caused her significant obstructing lower gastrointestinal and urinary symptoms besides the discomfort and disfigurement of the sacral region. Sacrococcygeal teratomas are commonly present early in life but are very rare to be seen in adults with such a huge size in such a place where it interfered with patient sitting and sleeping. Diagnosis of our case was suspected by clinical examination, ultrasound and MRI while histopathology confirmed the diagnosis. It was completely excised along with the coccyx with primary wound closure and had a good postoperative recovery. Up till now, 18 months follow-up using clinical, biochemical and radiological assessment revealed no evidence of recurrence. Sacococcygeal teratoma should be considered in the differential diagnosis of large pelvic masses in adults. In the presence of an extra-corporal and deep intra pelvic extension, we recommend the posterior perineal approach for excision as it has convenient control over the mass during surgery and good cosmetic results.
