Some specific microbiological parameters and prevalence of salmonella spp. in retail chicken meat from erzurum province, turkey and characterization of antibiotic resistance of isolates / Alguns parâmetros microbiológicos específicos e prevalência de SalmonellA spp. cortes de carne de frango da província de Erzurum, Turquia e caracterização da resistência aos antibióticos de isolados

Specific microbiological parameters and the presence of Salmonella spp. were investigated in 72 chicken meat samples (36 wings and 36 drumsticks) collected from markets and butcher shops. The specific microbiological parameters were determined using a conventional cultural method and the presence of Salmonella spp. in chicken samples was determined using conventional and immunomagnetic separation (IMS)-polymerase chain reaction (PCR) methods. In addition, antimicrobial susceptibility of the isolates was revealed using the Kirby-Bauer disc diffusion method. The results indicated that 30 of the 72 samples were positive for Salmonella spp. by the conventional method, and 42 of the 72 were positive by the IMS-PCR method. However, 30 of the 72 samples were positive for Salmonella spp. by both methods. The Salmonella spp. isolates were confirmed by the VITEK2 Compact System and PCR. The susceptibilities of the isolates against 10 antibiotics were determined. The results indicated that isolates (27/30) showed the highest susceptibility to gentamycin (90.00%), while the highest resistance was to nalidixic acid and tetracycline at the 100 and 93.34% levels, respectively. These results indicate a high prevalence of Salmonella spp. in poultry meat from Erzurum city, Turkey, and the antimicrobial resistance profile of these isolates should be considered for public health. The results also show that the IMS-PCR technique was superior to the conventional method for detecting Salmonella in poultry meat.KEYWORDS:Chicken meat. Salmonella. IMS. PCR. Antimicrobial. INTRODUCTION Chicken is one of the most popular food products worldwide, because of nutritional, sensorial and economic factors. Chicken is widely consumed in homes and fast-food establishments, but can become contaminated during processing. The contamination of poultry products with Salmonella and other microorganismsis due to unhygienic conditions during the production, processing, distribution, marketing and preparationstages (DOOKERAN et al., 2012). The genus Salmonella includes short rod-shaped, facultative anaerobe, Gram-negative bacteria. Warm-blooded animals and humans are natural hosts for Salmonella spp. Detecting Salmonella spp. during production and before consumption is important to prevent food-borne salmonellosis. A Salmonella infection in humans is usually caused by consuming undercooked meat or other cross-contaminated foods, such as vegetables,milk and eggs (HASSANEIN et al., 2011). According to a report published by the Centres for Disease Control and Prevention (CDC), it is estimated that about 1.2 million people in the US have been exposed to Salmonella infections, and that an average of 23.000 hospitalisations and 450 deaths occur from these infections. The prevalence rates of Salmonella spp. in chicken meat sold in Turkey are 34-68.75%. Not only in Turkey, but in most developing countries, the absence of an epidemiological surveillance system for salmonellosis cases makes it difficult to effectively assess prevalence (KÄFERSTEIN, 2003). However, Received: 09/05/18 Accepted: 05/12/18

Além disso, a suscetibilidade antimicrobiana dos isolados foi revelada pelo método de difusão do disco de Kirby-Bauer. Os resultadosindicaram que 30 das 72 amostras foram positivas para Salmonella spp. pelo método convencional, e 42 das 72 foram positivas pelo método IMS-PCR. No entanto, 30 das 72 amostras foram positivas para Salmonella spp. por ambos os métodos. Os isolados de Salmonella spp. foram confirmados pelo sistema VITEK2 Compact e PCR. As susceptibilidades dos isolados a 10 antibióticos foram determinadas. Os resultados indicaram que os isolados (27/30) apresentaram maior suscetibilidade à gentamicina (90,00%), enquanto a maior resistência foi ao ácido nalidíxico e à tetraciclina nos níveis de 100 e 93,34%, respectivamente. Estes resultados indicam uma alta prevalência de Salmonella spp. em carne de frango da cidade de Erzurum, Turquia, e o perfil de resistência antimicrobiana desses isolados deve ser considerado para a saúde pública. Os resultados também demonstram que a técnica de IMS-PCR foi superior ao método convencional para detecção de Salmonella em carne de frango.

Comparison between ABCD and IMS Scores in the Prediction of Long-Term T2DM Remission after Metabolic Surgery in East Asian Obese Patients

Recently, several scoring systems have been proposed to predict remission from type 2 diabetes mellitus (T2DM) after metabolic surgery. The ABCD score was compared to the individualized metabolic surgery (IMS) score in terms of the prediction of long-term T2DM remission; however, which of the two scoring systems is better remains controversial. Thus, Three East Asian countries Metabolic Surgery (TEAMS), which has been organized as a study group since 2016, is conducting a retrospective, international, multi-institutional study to compare the two scoring systems in East Asian obese patients after metabolic surgery. The primary study objective is to compare the ABCD score with the IMS score at 3 and 5 years after sleeve gastrectomy (SG), Roux-en-Y gastric bypass, one anastomosis gastric bypass and SG with duodenojejunal bypass. The secondary objectives include evaluating patients who were good candidates for SG, and adjusting the IMS scoring system for East Asian patients.

Diagnosis of canine leptospirosis using an immunomagnetic separation-PCR method

Diagnosis of leptospirosis by PCR is hampered due to the presence of substances on biological fluids. Here, we report an immunomagnetic separation step prior to PCR which improved the detection of Leptospira spp. in blood and urine samples from dogs. It resulted in a significant improvement on sensitivity for diagnosis of canine leptospirosis.

Infant and Young Child Feeding Guidelines: 2010.

Justification: The first National Guidelines on Infant and Young Child Feeding (IYCF) were formulated by Ministry of Women and Child Development (Food & Nutrition Board) in 2004, and the same guidelines were revised in 2006. India is committed to halving the prevalence of under weight children by 2015 as one of the key indicators of progress towards the Millennium Development Goals (MDG). By the end of 2009 nutritional achievement goals did not make for happy reading. So there was need to revise the existing guidelines and to have more viable and scientifically accepted national guidelines on Infant and Young child feeding. Process: A National Consultative Meet was organized by Indian Academy of Pediatrics at Gurgaon in 2009 where members of IYCF and Nutrition Chapters of IAP, BPNI, WHO, UNICEF, USAID, WFP were present. Each group made detailed presentations after reviewing recent literature on the subject. After extensive discussions a consensus was reached and the guidelines were formulated. Objectives: To formulate, endorse, adopt and disseminate guidelines related to Infant & Young Child feeding from an Indian perspective (including infant feeding in the context of HIV infection). Recommendations: Optimal infant and young child feeding: Early initiation of breastfeeding, exclusive breastfeeding for the first six month of life followed by continued breastfeeding for up to two years and beyond with adequate complementary foods is the most appropriate feeding strategy for infants and young children. Adequate nutrition and anemia control for adolescent girls, pregnant and lactating mother is also advocated.

A Case of Intramuscular Abscess in the Sternocleidomastoid Muscle after Intramuscular Stimulation(IMS)

PURPOSE: Intramuscular stimulation(IMS) shows good results in the treatment of chronic pain patients who did not respond to other treatments such as oral analgesics, trigger point injection, nerve block and epidural steroid injection. But, IMS procedure especially, patients with diabetes mellitus(DM) has sometimes serious problem. So, we present a very rare case of intramuscular abscess in the sternocleiomastoid muscle after IMS with literature review. METHODS: A 66 year old male visited our department 7 days after IMS in the neck. His premorbid conditions and risk factors of deep neck infection was DM and old age. Computed tomographic scans of the head and neck region were performed in this patient: signs of deep neck infection, were seen enhanced abscess in the sternocleidomastoid muscle, cellulitis overlying tissue of the neck, and air bubbles involved muscle. Necrotic wound was excised serially and we treated this with the Vacuum-assisted closure(VAC, Kinetics Concepts International, San Antonio, Texas) system device. After appropriately shaping the sponge in the pockets, continuous negative pressure of 125mmHg was applied. The VAC therapy was utilized for a period of 12 days. RESULTS: We obtained satisfactory results from wide excision, drainage of the abscess with the VAC system, and then primary closure. The postoperative course was uneventful. CONCLUSION: We suggest that many of the infectious complications may be preventable by strict adherence to aseptic techniques and that some of the other complications may be minimized by refining the techniques with a clear understanding of the medical disorders of patients. And, the refined technique using the VAC system can provide a means of simple and effective management for the cervical intramuscular abscess, with better cosmetic and functional results.

The effect of Gunn's intramuscular stimulation for postherpetic neuralgia: A report of 4 cases / 대한마취과학회지

Herpes zoster is the consequence of reactivation of latent varicella zoster virus from dorsal root ganglia. Postherpetic neuralgia (PHN) may be diagnosed when pain persists in a dermatomal pattern long after the vesicular erruption has healed. PHN is a kind of neuropathic pain. The pathophysiology of PHN is uncertain, but neuropathic pain due to denervation supersensitivity may be important to understand the pathophysiology of PHN. Numerous treatment have been introduced for the management of PHN, but no methods that results in complete remission. Gunn's intramuscular stimulation (IMS) is one of the best treatment of chronic pain, especially neuropathic pain. We tried Gunn's IMS for treatment of PHN patients affecting thoracic dermatomes. As a result, the visual analogue scale (VAS) was decreased from 7-8 to 2-3 and the result were satisfactory. The purpose of this case report is to introduce the Gunn's IMS and review our experience for the treatment of PHN.

Is intramuscular stimulation a safe procedure in unpracticed hands?: a case of cervical epidural hematoma resulting in hemiparesis: A case report

Intramuscular Stimulation (IMS) is a refined technique of traditional oriental acupuncture, and IMS has proved effective for relieving chronic pain of a neuropathic origin. IMS is currently seen to be quite a safe procedure with minimal complications having been reported to date. Various complications have been documented for acupuncture, but few complications or adverse effects have been reported in relation to the relatively new technique of IMS. We report here on a case of cervical spinal epidural hematoma that manifested as a cause of delayed hemiparesis. The safety of this procedure in unpracticed hands seems to be questionable.

Past, present and future of IMS

IMS is more than a needling technique. It has a background based on physiology, and needling depends upon a detailed knowledge of anatomy. The rationale conforms to Canon's law of denervation supersensitivity. Thus, IMS is a theoretical model that has the support of western physiologists. IMS worked by desensitizing supersensitive body segments. Therefore the technique needs detailed physical examination on segmental innervation area and needling skill to find accurate needling point. IMNS (Interventional Microadhesiolysis and Nerve Stimulation) works for hypersensitive joint soft tissue and FIMS (Fluoroscopy guided Interventional Microadhesiolysis and nerve Stimulation) works for hypersensitive nerve root, whereas classical IMS works for nerve stimulation due to muscle needling. In the future, we can adopt these techniques for brain disease according by Canon's law.

Two Cases of Iatrogenic Pneumothorax after Intra-Muscular Stimulation (IMS) Therapy / 결핵및호흡기질환

Recently, intra-Muscular Stimulation (IMS) therapy is being increasingly used for musculoskeletal pain. This procedure is generally regarded as a safe procedure for the general public. Some cases of iatrogenic pneumothorax caused by acupuncture have been reported in the medical literature. However, a case of an IMS therapy associated pneumothorax has not reported. We experienced two cases of iatrogenic pneumothorax after IMS therapy. A 62 year-old man received IMS therapy on the right shoulder due to posterior neck pain. After IMS therapy, acute dyspnea and chest discomfort developed. The other patient was a 74 year-old woman who also received IMS therapy. This patient experienced a nonproductive cough and acute dyspnea after the treatment. As the popularity of this form of alternative medicine increases, we might expect to see more cases of iatrogenic pneumothorax. Physicians should be aware of the adverse events associated with IMS therapy.

The Deep Dry Needling Techniques, and Interventional Muscle and Nerve Stimulation (IMS) for the Treatment of Chronic Pain / 대한통증학회지

Chronic pain can cause disability, mild to severe suffering and high medical costs. Some unfortunate patient do not improve despite administering conservative treatment and then the various interventional therapies, including oriental medical treatment and/or surgery, and they find themselves in search of a more effective pain relief. Deep dry needling is one of the newer treatment modalities for these patients. The last 10 years have seen a lot of progress in understanding the neural pathways and the type and extent of tissue involvement during chronic pain. This in turn has stimulated the development of new treatment techniques, and deep dry needling is one of them. So, the authors of this paper discuss the individual theories, the characteristics and future directions of several deep dry needling techniques, and we examine the new dry needling technique that has been recently developed in Korea.
