The Rare Congenital Anomaly of Scimitar Syndrome: An Unusual Presentation in Symptomatic Adult

@#Scimitar syndrome is a rare congenital heart defect occurring in 1 to 3 per 100,000 live births. This is a case of a 26 years old lady presenting with episodic fainting spells since the age of 18 years old. She was initially diagnosed with epilepsy until a referral to our centre found a soft splitting of the second heart sound and multiple premature ventricular complexes on ECG. The computed tomography of the pulmonary artery confirmed the diagnosis if Scimitar syndrome in the presence of anomalous single right pulmonary vein draining into infra-diaphragmatic systemic venous circulation. A corrective open-heart surgery to re-implant the pulmonary vein was performed with excellent clinical outcomes. Therefore, it is crucial for clinicians to embody high index of suspicion of congenital anomaly even in adults presenting with indefinite clinical symptoms. This report also represents the first published case of adult Scimitar syndrome from Malaysia.

Comparison of the efficacy and level of adherence for morning versus evening versus before bedtime administration of simvastatin in hypercholesterolemic patients

@#Background: Simvastatin is usually taken in the evening due to the circadian rhythm of hepatic cholesterol biosynthesis. The degree of reduction of low-density lipoprotein cholesterol (LDL-C) and the level of adherence to different administration time remained unknown in the Malaysian population. This study aims to investigate the effect of simvastatin on the percentage changes of lipid profile and the level of adherence to when simvastatin was instructed to be taken at different timing. Methods: Nine primary care health clinics across Malaysia participated in this study. 147 statin-naive subjects were selected through convenient sampling and randomised into one of the three arms (after breakfast, after dinner or before bedtime). Differences on percentage reduction of LDL-C from baseline and level of adherence among the three groups at week-16 were compared. The main outcomes measured in this study were the percentage change of lipid parameters and the percentage of high-adherence (MMAS=8) at week-16. Results: 59.2% of the patients were male. The mean age of the study population was 53.93± 10.85 years. Most of the patients were Malays (69.4%); followed by Indians (22.4%) and Chinese (8.2%). LDL-C decreased from 4.26 (Standard Deviation, SD1.01) to 2.36 (SD0.69)mmol/L at week-16 for patients taking simvastatin before bedtime; an absolute reduction of 44.95%.The differences of LDL-C percentage reduction between three arms were significantly different (p<0.001). The greatest LDL-C reduction was observed when simvastatin was taken before bedtime and revealed 56.2% patients with high-adherence at week-16. Conclusion: Simvastatin showed superior LDL-reduction and higher level of adherence when being instructed to be taken before bedtime

Effect of sumac extract on serum oxidative status, RANKL/OPG system and alveolar bone loss in experimental periodontitis in rats

Objectives Sumac (Rhus coriaria L.) is widely used spice which has several properties such as antioxidant, anti-inflammatory and antimicrobial. The purpose of this animal study was to evaluate the effects of sumac extract on levels of receptor activator of nuclear factor-kappa B ligand (RANKL), osteoprotegerin (OPG) expression, serum oxidative status, and alveolar bone loss in experimental periodontitis. Material and Methods Twenty-four Wistar rats were separated into three groups: non-ligated (NL, n=8), ligature only (LO, n=8), and ligature and treated with sumac extract (S, n=8) (20 mg/kg per day for 11 days). A 4/0 silk suture was placed around the mandibular right first molars subgingivally; after 11 days, the rats were sacrificed, and alveolar bone loss was histometrically measured. The detection of RANKL and OPG were immunohistochemically performed. Levels of serum total antioxidant status (TAS)/total oxidant status (TOS), and oxidative stress index (OSI) were also analyzed. Results Alveolar bone loss was significantly greater in the LO group compared to the S and NL groups (p<0.05). The number of inflammatory cell infiltrate (ICI) and osteoclasts in the LO group was significantly higher than that of the NL and S groups (p<0.05). The number of osteoblasts in the LO and S groups was significantly higher than that of the NL group (p<0.05). There were significantly more RANKL-positive cells in the LO group than in the S and NL groups (p<0.05). OPG-positive cells were higher in S group than in LO and NL groups (p<0.05). TOS and OSI levels were significantly reduced in S group compared to LO group (P<0.05) and TAS levels were similar in S and NL group (p>0.05). Conclusions The present study showed that systemic administration of sumac extract may reduce alveolar bone loss by affecting RANKL/OPG balance, TOS and OSI levels in periodontal disease in rats. .

Analysis of factors associated with lateral lymph node metastasis in mid and low rectal cancer / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the factors associated with lateral lymph node metastasis in middle and low rectal cancer.</p><p><b>METHODS</b>Clinical data of 203 patients with middle and low rectal cancer (within 10 cm from anal verge) undergoing lateral lymph node dissection in the Affiliated Cancer Hospital, Xinjiang Medical University between June 2004 to June 2010, were analyzed retrospectively. Logistic regression analysis was used to screen the associated factors.</p><p><b>RESULTS</b>The total number of harvested lateral lymph node was 3349, and average number was 17 per case. The number of positive lateral lymph node was 221, and the lymph node metastasis ratio was 6.6%(221/3349). Univariate analysis showed that age, family history, tumor length, gross type of tumor, histological type, differentiation, depth of invasion, invasion of circumference, serum CEA, tumor thrombus and upper lymph node metastasis were associated with rectal cancer metastasis(P<0.05). Multivariate analysis showed that age, histological type, infiltration depth, gross type, differentiation degree and upper lymph node metastasis were the independent risk factors of the lateral lymph node metastasis in middle and low rectal cancer(P<0.05).</p><p><b>CONCLUSION</b>For patients who is young, or with poorly differentiated cancers, infiltrative type, T4 cancer, or those with upper lymph node metastasis, lateral lymph resection may be indicated because of high risk of lateral node metastasis.</p>

Buddhist Mothers’ Experience of Suffering and Healing After the Accidental Death of a Child

Abstract: Numerous nursing studies have examined suffering, but none have addressed the suffering and healing Buddhist mothers experience after the accidental death of a child. The purpose of this study was to gain understanding of the meaning of sufferingand the practices of healing and suffering, among Buddhist mothers after such a loss. Buddhist concepts provided the philosophical framework, and Gadamerian hermeneutic phenomenology provided the methodological framework, for this investigation.Ten Buddhist mothers were recruited from a government hospital in Songkhla province, Thailand. In-depth interviews were conducted and data were analyzed using hermeneutics. Five themes that reflected the meaning of suffering amongBuddhist mothers, after the accidental death of a child, were identified. They included: the mother’s heart was torn into pieces; the mother’s body was frozen andshe was uncertain she would survive; happiness in the mother’s life was missing; the mother’s anger and rage at self and others; and, the mother worried and wondered about the next life of her deceased child. The mothers were found to heal their suffering by: transforming their relationship with the deceased child; elevating the deceased child to be a very good child capable of going to heaven; making merit in order to pass the benefit to the deceased child; self-healing through understanding and mind cultivation; and, seeking support. The findings promote the  understanding of the suffering and coping of Buddhist mothers whose child accidentally died.
