Risk Stratification in People with Diabetes for Fasting During Ramadan: Consensus from Arabic Association for the Study of Diabetes and Metabolism.

BACKGROUND: Current international guidelines recommend a pre-Ramadan risk assessment for people with diabetes (PwDM) who plan on fasting during the Holy month. However, a comprehensive risk assessment-based recommendation for the management of PwDM intending to fast is still controversial. Therefore, the Arabic Association for the Study of Diabetes and Metabolism (AASD) developed this consensus to provide further insights into risk stratification in PwDM intending to fast during Ramadan. METHODS: The present consensus was based on the three-step modified Delphi method. The modified Delphi method is based on a series of voting rounds and in-between meetings of the expert panel to reach agreements on the statements that did not reach the consensus level during voting. The panel group comprised professors and consultants in endocrinology (both adult and pediatric). Other members included experts in the fields of cardiovascular medicine, nephrology, ophthalmology, and vascular surgery, affiliated with academic institutions in Egypt. RESULT: In PwDM who intend to fast during Ramadan, risk stratification is crucial to optimize patient outcomes and prevent serious complications. The present consensus provides risk assessment of those living with diabetes according to several factors, including the type of diabetes, presence, and severity of complications, number of fasting hours, and other socioeconomic factors. According to their risk factors, patients were classified into four categories (very high, high, moderate, and low risk). CONCLUSION: Future research is warranted due to the controversial literature regarding the impact of fasting on certain comorbidities.

Amniotic membrane can be a valid source for wound healing.

UNLABELLED: Amniotic membrane (AM) can promote proper epithelialization with suppression of excessive fibrosis by creating a supportive milieu for regeneration of chronic ulcer bed. OBJECTIVE: The objective of this study is to investigate whether AM scaffold can modulate the healing of a wound by promoting tissue reconstruction rather than promoting scar tissue formation. SUBJECTS AND METHODS: AM was obtained and prepared and then applied to patients with chronic leg ulcers who were randomly divided into two different groups. Group I (control group) included eleven patients in whom ulcers were treated with conventional wound dressings that were changed daily for 8 weeks. Group II (study group) included 14 patients in whom the AM was placed in contact with the ulcer and held in place with a secondary dressing, which was changed daily. Follow-up was done to detect healing rate and detection of ulcer size, assessment of pain, and to take ulcer images (days 0, 7, 14, 21, 30, 45, and 60). RESULTS: In group I, all ulcers showed no reduction in their size, and ulcer floor remained the same. Healthy granulations were present in two ulcers (18.2%) and absent in nine ulcers (81.8%). There was no improvement of pain level in the eleven ulcers. In group II, complete healing of 14 ulcers occurred in 14-60 days with a mean of 33.3±14.7; healing rate range was 0.064-2.22 and the mean 0.896±0.646 cm(2)/day. Healthy granulations were present in 13 ulcers (92.9%) and absent in one ulcer (7.1%). Three ulcers (21.4%) were of mild severity (grade 1 ulcers) while eleven ulcers (78.6%) were of moderate severity (grade 2 ulcers). The healing rate was faster in ulcers of mild severity (1.7±0.438 cm(2)/day) in comparison to ulcers of moderate severity (0.673±0.498 cm(2)/day). Eleven cases (78.6%) showed improvement in their pain level on a scale from 0 to 10. CONCLUSION: AM graft can be of value in wound healing. Further studies are needed to confirm these findings.

Management of critical lower limb ischemia in endovascular era: experience from 511 patients.

This study aims at the assessment of the achievability of the endovascular treatment of patients with critical limb ischemia (CLI) and the role of bypass in such patient. This is a prospective study conducted on patients with chronic atherosclerotic critical lower limb ischemia presenting to us over a period of 3 years. Patients presenting with nonsalvageable limbs requiring primary major amputation and nonatherosclerotic causes of CLI were excluded. Endovascular treatment was the first choice modality of treatment in revascularization of all patients. Open surgery was offered selectively for patient whom endovascular failed or complicated and for long TransAtlantic Inter-Society Consensus (TASC) II lesions in fit patients. This study included 511 cases of CLI, and the mean age was 64.5 years. Patients with Rutherford IV, V, and VI were 19.25, 60.5, and 19.25%, respectively. The TASC II aortoiliac lesions were as follows: A, B, C, and D in 33.7, 12,15.7, and 38.6%, respectively, and infrainguinal lesions were A, B, C, and D in 3.7, 19, 35.4, and 68.3%, respectively. A total of 78.3% of patients were treated by endovascular totally, while 16% were treated by surgery from the start, 3.7% of endovascular cases were converted to open surgery after failure of endovascular treatment, and 2% was offered hybrid treatment. Crossing of lesions by subintimal and intraluminal was 12.5 and 87.5%, respectively. Technical success in endovascular was 94%; however, we could successfully revascularize 96.8% of all CLI presented in this study by either surgery or endovascular. On 24 months follow-up, primary patency, secondary patency, and limb salvage by percutaneous transluminal angioplasty are 77.8, 84.7, and 90.7%, respectively. Revascularization by endovascular achieves high technical success and limb salvage in CLI, hence should be considered as preferred choice of treatment. However, both endovascular and surgery should not be counteracting each other and using both can revascularize 96.6% of CLI.

Carotid body tumors: a review of 25 years experience in diagnosis and management of 56 tumors.

OBJECTIVE: To report our experience in the management of CBTs and review the literature. MATERIALS AND METHODS: 56 CBTs were operated upon over a period of 25 years. Surgical intervention was planned according to the Shamblin classification. Thirty-nine of the tumors were in males (69.64%), and 17 of the tumors were in females (30.36%). The average age was 42 (ages ranging between 32 and 47). Twenty-two tumors were diagnosed and treated with Shamblin type I, twenty-eight with type II and eight tumors with type III. All patients were unilateral except two had bilateral carotid tumors. Thirty-five lumps were de novo (group A), while 21 lumps were treated after a prior trial of removal (group B). RESULTS: The incidence of carotid reconstruction was lower among group A (1/35) compared to group B (9/21). Complications were less in group A than group B (23% vs. 30%). There were 4 cases with suspected malignancy and no recurrences during the follow-up period. CONCLUSION: There is an increased incidence of major vascular reconstruction in cases not properly investigated or diagnosed and in cases with prior attempts of removal in Primary Hospitals. Proper diagnosis of suspicious lumps is mandatory. Resection of CBTs by surgeons with experience in vascular reconstruction is recommended. Vascular reconstructions have to be performed safely without serious complications. Also today, prior attempts of removal are not so common, with preoperative evaluation using the latest diagnostic tools. Cranial nerves injury (especially the Hypoglossal Nv) continues to be the most common complication.
