The Long-Term Outcomes Following the Application of Intralesional Epidermal Growth Factor in Patients With Diabetic Foot Ulcers

Epidermal growth factor is used as an adjuvant to close the wound in addition to standard care in diabetic foot ulcers. This study aimed to investigate the long-term outcomes after intralesional epidermal growth factor injections in the treatment of diabetic foot ulcers. Thirty-six feet of 34 patients (n?=?34) with diabetic foot ulcers were included. Patient demographics, Wagner classifications, recurrence and amputation rates, Foot Function Index, Short Form 36, and American Academy of Orthopedic Surgeons Foot and Ankle Module scores were evaluated at the final follow-up examination. The mean age was 61.000 ± 13.743 years. The mean duration of wounds was 240.200 ± 146.385 days. A mean of 18.125 ± 4.494 (range 9 to 24) doses were applied. Wound closure was achieved in 33 of the 36 (91.7%) lesions. A complete response (granulation tissue >75% or wound closure) was observed in 29 (87.9%) lesions. The mean time to wound closure was 52.08 ± 10.65 (range 25 to 72) days. At the 5-year follow-up, 4 patients were lost to follow-up because of exitus owing to diabetic complications. Of the remaining 29 patients, 27 were ulcer free. In 2 patients (2 lesions, 6.9%) toe amputation was performed due to ischemic necrosis. The mean Foot Function Index, American Academy of Orthopedic Surgeons Foot and Ankle Core Scale, and AAOS Shoe Comfort Scale scores were 55.40 ± 12.15, 65.92 ± 17.56, and 56.42 ± 11.98, respectively. Complete wound healing and a low recurrence and amputation rates could be obtained with intralesional epidermal growth factor added to the standard treatment protocol.     

Is There Equipoise Regarding the Optimal Medical Treatment of Patients with Asymptomatic White Matter Hyperintensities?

Background: White matter hyperintensity (WMH) is a common manifestation of chronic ischemic microvascular disease that heralds greater risk of functional disability, stroke, and dementia. SPRINT MIND recently reported that intensive blood pressure reduction resulted in lower rates of mild cognitive impairment and WMH progression, suggesting that medical interventions could have a measurable impact on WMH. We conducted an anonymous survey of providers in the NINDS StrokeNet to better understand neurologist attitudes about asymptomatic WMH. Methods: We sent a 7-question survey to the 29 Regional Coordinating Centers of the StrokeNet, whose coordinators disseminated the survey to providers “involved in the care of a patient after their stroke.” Results: We received 136 responses. For stroke prevention therapies, including aspirin and statin therapy and blood pressure target, there was substantial equipoise, with no single option receiving >50% endorsement and between 15-32% of respondents choosing the option of “not sure.” 83% of respondents indicated high or moderate enthusiasm for a trial targeting this patient population. The clinical outcomes of reduction in ischemic stroke, cognitive impairment, or dementia were high importance (>70% endorsement), while the remaining radiographic, safety, and clinical endpoints all failed to reach 50% endorsement. Conclusions: Our survey establishes meaningful neurologist attitudes that can inform future WMH research. There is considerable equipoise regarding optimal medical treatment for patients with asymptomatic WMH and providers in StrokeNet, who would be a vital stakeholder in WMH research in the United States, enthusiastically support a clinical trial to resolve open questions on optimal medical management.     

Bilateral optic disc pathologies as an accompanying feature of comitant strabismus in children

Purpose

To describe and report accompanying bilateral optic disc pathologies in children with comitant strabismus.

Methods

Twenty-eight patients (16 female, 12 male) aged between 1 and 12 years who had comitant strabismus and bilateral optic disc pathologies were included in the study. Visual acuity, refractive errors, amount of deviation and types of optic disc pathologies were all recorded. Each patient underwent complete neurological and ophthalmological examination.

Results

Of the 28 patients, 14 (50.0%) had esotropia and 14 (50.0%) had exotropia. The mean age was 4.18 ± 3.03 years. The mean deviation angle was 35.30 ± 13.26 prism diopters (PD) (20–70 PD). Optic atrophy as being the most common pathology was found in nine (32.1%) patients. Six (21.4%) patients had temporal disc pallor, six (21.4%) patients had optic nerve hypoplasia, and seven (25%) patients had other optic disc anomalies (tilted disc, megalodisc, disc coloboma, peripapillary staphyloma). Optic disc pathologies were found to be isolated in 12 patients. Nine of 13 patients with congenital optic disc pathologies had esotropia, whereas 10 of 15 patients with optic atrophy or optic disc pallor had exotropia.

Conclusion

Comitant strabismus in children can be associated with congenital or acquired optic disc pathologies. It is worthy of note that esotropia was more common in patients with congenital optic disc pathologies, whereas exotropia was more frequent in patients with optic atrophy or optic disc pallor. The findings of the present study show that complete ophthalmological examination including fundus evaluation should be carried out in all patients with strabismus even though the cause of ocular misalignment is obvious.

     

Changes in endothelial cell density following penetrating keratoplasty and deep anterior lamellar keratoplasty

AIM: To compare the corneal endothelial cell density (ECD) of clear grafts after penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK). METHODS: The study included 44 and 54 patients treated with PK and DALK, respectively, between March 2006 and April 2010. Corneal ECD was examined using specular microscopy at postoperative 1, 3, 6, 12, and 18 months, and the values were compared. RESULTS: Corneal ECD reduction in the PK group was 7.4%, 15.2%, 23.5%, and 28.9% at 3, 6, 12 and 18 months respectively after surgery, compared with 4.2 % in the first month (P<0.01). These figures were 3.0%, 6.7%, 7.2%, and 7.7% at 3, 6, 12 and 18 months respectively, compared with 2.2 % in the first month in the DALK group (P>0.05). CONCLUSION: Compared with DALK,PK significantly reduced ECD of the clear grafts. These results suggest that survival of endothelial cells in grafts is better after DALK than after PK.     

Evaluation of diagnosis and treatment results in children with Graves' disease with emphasis on the pubertal status of patients

This retrospective study evaluated the clinical and laboratory characteristics at presentation and treatment results of patients with Graves' disease (GD) with respect to pubertal status. Records of 143 patients (108 F, 35 M) were reviewed in a multicenter study. At diagnosis, 38% of patients were prepubertal. Anti-thyroid drugs (ATD) were used as initial therapy. There was no significant difference in clinical and laboratory characteristics at diagnosis, during treatment and adverse reaction to ATD with respect to pubertal status. Twenty patients (7 prepubertal, 13 pubertal) reached remission on ATD. Surgery was performed in seven and radioiodine (RAI) in four patients. Duration of treatment needed to achieve remission was longer in prepubertal (4.2 +/- 1.0 yr) than in pubertal patients (3.1 +/- 1.3 yr) (p = 0.02). The rate of remission was not different between prepubertal (25.9%) and pubertal patients (33.3%) (p = 0.59). ATD were associated with low remission rate in pediatric GD and required longer duration of therapy in prepubertal patients. For definitive treatment in older children, RAI could be evaluated as the initial therapy.     

Heart type fatty acid binding protein response and subsequent development of atherosclerosis in insulin resistant polycystic ovary syndrome patients

Background

Women with polycystic ovary syndrome (PCOS) have higher risk for cardiovascular disease (CVD). Heart type fatty acid binding protein (HFABP) has been found to be predictive for myocardial ischemia.Wet ested whether HFABP is the predictor for CVD in PCOS patients, who have an increased risk of cardiovascular disease.

Methods

This was a prospective, cross sectional controlled study conducted in a training and research hospital.The study population consisted of 46 reproductive-age PCOS women and 28 control subjects. We evaluated anthropometric and metabolic parameters, carotid intima media thickness and HFABP levels in both PCOS patients and control group.

Results

Mean fasting insulin, homeostasis model assessment insulin resistance index (HOMA-IR), triglyceride, total cholesterol, low density lipoprotein cholesterol, free testosterone, total testosterone, carotid intima media thickness (CIMT) levels were significantly higher in PCOS patients. Although HFABP levels were higher in PCOS patients, the difference did not reach statistically significant in early age groups. After adjustment for age and body mass index, HFABP level was positive correlated with hsCRP, free testosterone levels, CIMT and HOMA-IR.

Conclusions

Heart type free fatty acid binding protein appeared to have an important role in metabolic response and subsequent development of atherosclerosis in insulin resistant, hyperandrogenemic PCOS patients.

     

Effect of isotretinoin treatment on plasma holotranscobalamin, vitamin B12, folic acid, and homocysteine levels: non-controlled study

Isotretinoin (Iso) has been used for the treatment of acne. Some previous studies reported elevated homocysteine (Hcy) levels after treatment with Iso. Some side effects have clinical presentations similar to vitamin B12, folic acid deficiencies, and hyperhomocysteinemia. In the present study we evaluated the plasma Hcy levels, the vitamins involved in its metabolism (vitamin B12 and folic acid), and holotranscobalamin (HoloTC), a transport system for vitamin B12 absorption in patients receiving Iso treatment for acne vulgaris. A total of 66 patients with acne vulgaris between the ages of 18 and 40 years were included. Screening for hemoglobin, creatinine, SGOT, SGPT, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and very low-density lipoprotein cholesterol (VLDL-C), folic acid, vitamin B12, Hcy, and HoloTC were done just before initiation (pretreatment) and after four months of Iso treatment (posttreatment). Posttreatment vitamin B12, folic acid, and HoloTC levels were significantly lower while Hcy levels were significantly higher compared with initial values. Posttreatment total cholesterol, LDL-C, triglycerides, VLDL-C, SGPT, and SGOT levels were also higher, and HDL-C levels were lower compared with initial values while there was no change in hemoglobin levels during Iso treatment. We found that Iso usage might cause decreased vitamin B12, folic acid, and HoloTC. These Iso side effects might contribute to the missing link between Iso usage, hyperhomocysteinemia, and neuropsychiatric disorders. Trials may be made with the aim of demonstrating (clearly) if starting vitamin B12 and folic acid replacement therapies with Iso treatment initialization could be useful for preventing hyperhomocysteinemia and possibly related disorders.     

Effects of preoperative carbohydrate loading on glucose metabolism and gastric contents in patients undergoing moderate surgery: a randomized, controlled trial

OBJECTIVE: Despite contrary evidence, the practice of overnight fasting before elective surgery maintains its place in tradition. However, prolonged starvation, by its catabolic action, may increase the detrimental effects of surgery. In this study, we evaluated the effects of preoperative carbohydrate loading on the gastric contents of patients and perioperative metabolism. METHODS: Seventy patients scheduled for cholecystectomy or thyroidectomy randomly were assigned to the treatment or control group. Patients in the treatment group (n = 34) received 800 mL of a carbohydrate-rich fluid on the evening before surgery and 400 mL of the same fluid 2 h preoperatively. Conversely, control patients (n = 36) underwent overnight fasting. Plasma glucose and serum insulin levels were obtained across the perioperative period and during anesthesia induction. The volume and pH of preoperative residual gastric contents also were measured. RESULTS: Preoperative plasma glucose levels were found to remain significantly higher in patients who had received the carbohydrate-rich fluid. Serum insulin levels that were elevated initially in the study group returned to control levels by the time of anesthesia induction. There was no statistical difference between the two groups with respect to gastric residue contents or gastric fluid pH. CONCLUSION: The preoperative intake of carbohydrate-rich fluids does not appear to alter the amount or pH of gastric contents, suggesting that this is a safe procedure, in terms of aspiration risk. Furthermore, the intake of such fluid might prevent energy malnutrition.
