Balloon valvotomy for pregnant patients with severe pliable mitral stenosis using the Inoue technique with total abdominal and pelvic shielding.

Balloon valvotomy by means of the Inoue technique was attempted in seven pregnant (5 to 9 months) patients with severe mitral stenosis; the mean age of the patients was 32 +/- 8 years, and all had a two-dimensional echocardiographic mitral valve score of < 8. Indications for Inoue balloon valvotomy included severe symptomatic mitral stenosis with a Doppler mitral valve area < or = 1 cm2 and heart failure refractory to medical therapy, or absolute contraindications for the use of beta-blockade; Inoue valvotomy was also indicated for patients who lived a long distance from the hospital. Inoue balloon valvotomy was performed with no angiography and total pelvic and abdominal shielding; the balloon catheter was introduced into the right atrium without the aid of fluoroscopy, which was used for the transseptal puncture. Stepwise two-dimensional echocardiographic Doppler mitral valve dilatation was done. After Inoue balloon valvotomy the mean Doppler mitral valve area increased from 0.8 +/- 0.1 to 2.0 +/- 0.3 cm2 (p < 0.01) and by two-dimensional echocardiography from 0.8 +/- 0.2 to 1.9 +/- 0.3 cm2 (p < 0.01), with no significant Doppler residual stenosis (defined as mitral valve area < or = 1.5 cm2). The mean total fluoroscopy time was 16 +/- 7 minutes. The degree of mitral regurgitation increased in two patients from grade 1+/4+ to grade 2+/4+ and from grade 0+/4+ to grade 2+/4+, respectively. There was no mortality or significant morbidity. Pregnancy was uneventful in all patients, and all were delivered of normal babies without complications.(ABSTRACT TRUNCATED AT 250 WORDS)     

Effect of mucosal thickening near gastric carcinoma on the endoscopic diagnosis of malignancy

Gastric mucosal thickening of variable degree occurs in the vicinity of gastric carcinomas and is possibly related to simultaneous tumor expression of epidermal growth factor and its receptor. Seventeen cases in which both endoscopic biopsy and subsequent resection for gastric carcinoma had been performed were studied to see if putative tumor-related mucosal thickening had an effect on endoscopic biopsy sensitivity. Biopsy fragment positivity rate was greater in cases with exophytic, protruding tumor masses (46.8± 8.5%) than in all other cases (17.0± 4.7%; P=0.02). Thickness of nontumorous mucosa adjacent to carcinomas did not significantly affect the biopsy fragment positivity rate in cases with exophytic masses (thin subgroup, 51.0±16.2%; thick subgroup, 44.0±10.8%; P=0.7) but did reduce the positivity rate significantly (P=0.05) in ulcerative or infiltrative tumors without exophytic components (thin subgroup, 23.3±4.1%; thick subgroup, 8.4±2.1%). This reduction in biopsy sensitivity related to mucosal thickening occurring adjacent to nonprotuberant lesions may explain, at least in part, the variable rates of positive biopsies observed with gastric cancers.Supported in part by a grant (AM07130) from the United States Public Health Service.     

Ocular Manifestations in Egyptian Children and Young Adults with Sickle Cell Disease

In sickle cell disease (SCD), ocular lesions result from stasis and occlusion of small eye vessels by sickled erythrocytes. Vaso-occlusive disease of the retina can be responsible for nonproliferative (NPR) and proliferative retinopathy (PR). Patients are often asymptomatic until serious complications arise as, vitreous hemorrhage and retinal detachment. This work aimed to study the frequency and pattern of ocular manifestations in Egyptian children and young adults with SCD. In this cross-sectional study, 40 steady state patients (80 eyes) aged 2–28 years (30 children and 10 young adults) with established diagnosis of SCD (26 with homozygous SS and 14 with S/β thalassemia underwent complete ophthalmic examination with dilated fundoscopy. Fluorescein angiography was performed for patients ≥12 years old. The overall frequency of retinal lesions was 47.5 % (46.2 and 50 % of SS and S/β patients respectively). PR and NPR were evident in 32.5 and 27.5 % of all enrolled patients respectively (five patients having both). Peripheral retinal occlusion was a frequent ocular finding in both groups; the youngest patient showing PR was 15 years old. Older age, longer disease duration and splenectomy were significantly more prevalent among patients with PR. Despite lack of visual symptoms, children and young adults are at risk of PR. Frequency of retinal lesions was comparable in SS and S/β patients. Periodic ophthalmologic examination starting at the age of 12 years is recommended for timely-identification of retinal lesions thus minimizing the risk of sight threatening retinopathy.     

Pharmacists’ contributions to the delivery of pharmaceutical care to patients with type 2 diabetes in Kuwait

This study was designed to identify pharmacists’ potential contributions to the delivery of pharmaceutical care to patients with type 2 diabetes in Kuwait, and to identify and explore barriers that were preventing them from providing care to this specific group. A pretested self-administered questionnaire was distributed to all pharmacists registered in the Kuwait Pharmaceutical Association’s email registry (N?=?250). Invitations to a focus group interview were then sent to all pharmacists (N?=?50) who had responded to the questionnaire. Seven pharmacists accepted the invitation and participated in the focus group interview. Of the 50 respondents to the questionnaire, 31 (62.0 %; 95 % CI: 47.2–75.4) indicated that they were “comfortable” and “extremely comfortable” in discussing patient’s blood pressure target and annual screening with physicians rather than discussing smoking cessation advice or specific medication-related care issues. More than 75 % of the respondents were “comfortable” and “extremely comfortable” in sharing and verifying the patient’s drug history, blood pressure, cholesterol and stability of blood glucose with the healthcare team, and to maintain a pharmaceutical care plan for patients with diabetes. Overall, pharmacists indicated that they were more comfortable in undertaking clinical activities than discussing care issues with physicians. The focus group interview identified issues related to pharmacist-physician interaction, pharmacists’ confidence, pharmacists’ image by patients and physicians and barriers to implementing pharmaceutical care. This study shows that pharmacists in Kuwait perceive that their contribution to the delivery of pharmaceutical care could develop further with increased partnership between pharmacists and physicians and provision of further education, training and continuing professional development support.     

Enhanced Recovery After Bariatric Surgery (ERABS): Clinical Outcomes from a Tertiary Referral Bariatric Centre

There is paucity of data on Enhanced Recovery After Bariatric Surgery (ERABS) protocols. This feasibility study reports outcomes of this protocol utilized within a tertiary-referral bariatric centre. Data on consecutive primary procedures (laparoscopic gastric bypasses, sleeve gastrectomies and gastric bands) performed over 9 months within an ERABS protocol were prospectively recorded. Interventions utilized included shortened preoperative fasts, intra-operative humidification, early mobilization and feeding, avoidance of fluid overload, incentive spirometry, use of prokinetics and laxatives. Data collected included demographics, co-morbidities, morbidity, mortality, length of stay (LOS) and re-admissions. A total of 226 procedures (age [mean ± SD], 45?±?11 years, median [interquartile range] BMI 44.9 [41.0–49.0] kg/m²) were undertaken: 150 (66 %) bypasses, 47 (21 %) sleeves and 29 (13 %) bands. Hypertension, diabetes mellitus, sleep apnea and limited mobility were present in 40 %, 34 %, 24 % and 9 % of patients, respectively. No anastomotic or staple line leaks/bleeds were encountered. Ten (4.4 %) patients developed postoperative morbidity (mainly respiratory complications). One death occurred from massive pulmonary embolus in a high-risk patient (despite insertion of preoperative-IVC filter). Respective mean ± SD LOS for bypasses, sleeves and bands were 1.88?±?1.12, 2.30?±?1.69 and 0.69?±?0.81 days. Successful discharge on the first postoperative day was achieved in 37 % and 28 % of bypasses and sleeves, respectively. Day-case gastric bands were performed in 48 %. Thirty-day hospital re-admission occurred in six (2.7 %) patients. Applying an ERABS protocol was feasible, safe, associated with low morbidity, acceptable LOS and low 30-day re-admission rates. The presence of multiple medical co-morbidities should not preclude use of an ERABS protocol within bariatric patients.     

FLS tasks can be used as an ergonomic discriminator between laparoscopic and robotic surgery

Introduction

Robotic surgery may result in ergonomic benefits to surgeons. In this pilot study, we utilize surface electromyography (sEMG) to describe a method for identifying ergonomic differences between laparoscopic and robotic platforms using validated Fundamentals of Laparoscopic Surgery (FLS) tasks. We hypothesize that FLS task performance on laparoscopic and robotic surgical platforms will produce significant differences in mean muscle activation, as quantified by sEMG.

Methods

Six right-hand-dominant subjects with varying experience performed FLS peg transfer (PT), pattern cutting (PC), and intracorporeal suturing (IS) tasks on laparoscopic and robotic platforms. sEMG measurements were obtained from each subject’s bilateral bicep, tricep, deltoid, and trapezius muscles. EMG measurements were normalized to the maximum voluntary contraction (MVC) of each muscle of each subject. Subjects repeated each task three times per platform, and mean values used for pooled analysis. Average normalized muscle activation (%MVC) was calculated for each muscle group in all subjects for each FLS task. We compared mean %MVC values with paired t tests and considered differences with a p value less than 0.05 to be statistically significant.

Results

Mean activation of right bicep (2.7 %MVC lap, 1.3 %MVC robotic, p = 0.019) and right deltoid muscles (2.4 %MVC lap, 1.0 %MVC robotic, p = 0.019) were significantly elevated during the laparoscopic compared to the robotic IS task. The mean activation of the right trapezius muscle was significantly elevated during robotic compared to the laparoscopic PT (1.6 %MVC lap, 3.5 %MVC robotic, p = 0.040) and PC (1.3 %MVC lap, 3.6 %MVC robotic, p = 0.0018) tasks.

Conclusions

FLS tasks are validated, readily available instruments that are feasible for use in demonstrating ergonomic differences between surgical platforms. In this study, we used FLS tasks to compare mean muscle activation of four muscle groups during laparoscopic and robotic task performance. FLS tasks can serve as the basis for larger studies to further describe ergonomic differences between laparoscopic and robotic surgery.     

Vitamin D deficiency in children with bronchial asthma in southern Jordan: a cross-sectional study

ObjectivesTo assess serum 25-hydroxycholecalciferol (25-OH vitamin D) levels in Jordanian children with bronchial asthma, and to examine correlations between 25-OH vitamin D levels and asthma severity and control.MethodsA cross-sectional study was conducted at the Paediatric Chest Clinic, Al-Karak Governmental Hospital, Southern Jordan, between May 2015 and February 2016. Serum 25-hydroxyvitamin D level was determined in children aged 1–14 years diagnosed with bronchial asthma (6–14 years) or recurrent wheezing episodes (<6 years). Asthma severity was determined based on the Global Initiative for Asthma assessment, the Asthma Control Test, and the Childhood Asthma Control Test. Demographic and clinical characteristics were compared between patients with low and normal 25-OH vitamin D levels, and correlations between asthma severity and 25-OH vitamin D level were assessed.ResultsOut of 98 included children, 25-OH vitamin D levels were deficient and insufficient in 41 (41.8%) and 34 (34.7%) children, respectively. Only 23 (23.5%) had sufficient 25-OH vitamin D levels. A significant correlation was found between severity of asthma symptoms and 25-OH vitamin D deficiency.Conclusion25-OH vitamin D deficiency is highly prevalent in Jordanian children with bronchial asthma and correlates significantly with asthma severity.     

Metastatic Osteosarcoma to the Interventricular Septum: An Unusual Presentation in a Child

Whereas primary cardiac tumors are reported in only 0.17 % of pediatric patients, malignant cardiac tumors are even less common in children. This report presents a 10-year-old child with relapsed osteosarcoma manifesting as metastatic lesions to the interventricular septum.
