Paraduodenal hernias are also called mesocolic hernias. Mesocolic hernias are unusual congenital hernias in which small intestine herniates behind mesocolon. They can be discovered incidentally during laparotomy for intestinal obstruction or during radiological investigations. This is a case report of left paraduodenal hernia diagnosed intraoperatively after being operated on in emergency setting for intestinal obstruction. The mouth of the sac was obliterated by suture apposition to the posterior wall. The patient was discharged on day 7 after an uneventful recovery.
十二指肠旁疝也称为肠系膜疝。结肠系膜疝是一种罕见的先天性疝,小肠在结肠系膜后疝出。它们可在剖腹探查肠梗阻或放射检查时偶然发现。本文报告一例因肠梗阻急诊手术后,术中诊断为左侧十二指肠旁疝的病例。囊口被缝合至囊后壁。病人在康复后的第7天出院。

Aim: To evaluate and compare safety and efficacy of PPIUCD in two groups of patients: vaginal insertion group after normal delivery and intra cesarean insertion group. Methods: A prospective study carried out in the Department of Obstetrics and Gynecology at a tertiary care center. After counseling with patients and her relatives during antepartum period, IUCD insertion was done in 1438 patients. In 417 patients IUCD was inserted vaginally. In 1021 patients IUCD was inserted while cesarean section. All these patients were followed up after 6 weeks and after 6 months interval regularly. All the complications were recorded and studied. Incidence, clinical outcome & missing threads were analyzed. Results: Both the methods of PPIUCD insertion were safe and efficacious. Out of 1438 women ,1340 cases had follow up as per the protocol. Fifty eight cases who lost for follow up and 40 cases who had spontaneous expulsion, were excluded from study. There were missing strings in 363 cases at 6 weeks examination and in 338 cases at 6 months follow up examination. Ultrasonography of pelvis establishes IUCD location in uterine cavity. Neither perforation nor pregnancy with PPIUCD was found in present study. They have low rates of abdominal pain, pelvic infection, heavy menstruation and lost strings. Conclusion: PPIUCD is an appealing approach and may become a choice of post-partumcontraception. It is safe and effective method of reversible contraception.Missing strings after PPIUCD insertion is a common problem encountered during follow up examination. Every user must be followed up and provider must take better aftercare in forms of follow up and management of complication if needed.
目的:评价和比较正常分娩后阴道插入组和剖宫产内插入组PPIUCD的安全性和有效性。方法:在某三级保健中心的妇产科进行前瞻性研究。1438例患者经产前咨询患者及家属后,行宫内节育器植入术。417例患者宫内节育器经阴道置入。1021例患者在剖宫产术中置入宫内节育器。所有患者每隔6周和6个月定期随访。对所有并发症进行记录和研究。分析发生率、临床结果及缺失线。结果:两种方法均安全有效。在1438名妇女中,1340例按照协议进行了随访。58例失踪者和40例自发性排尿者被排除在研究之外。随访6个月338例,随访6周363例。盆腔超声检查确定宫内节育器位置。本研究未发现PPIUCD穿孔或妊娠。他们的腹痛、盆腔感染、月经量大和尿道丢失的几率很低。结论:PPIUCD是一种有吸引力的方法,可能成为产后避孕的选择。是一种安全有效的可逆避孕方法。PPIUCD插入后漏串是随访检查中常见的问题。每个用户都必须接受随访,如果需要,提供者必须采取更好的随访和并发症管理形式的善后护理。

Introduction:Hypertension is an important worldwide public-health challenge because of its high frequency and concomitant risks of cardiovascular and kidney disease.Hypertension is the new era pandemic which is the leading cause of mortality in the world and is ranked third as a cause of disability-adjusted life years. Various risk factors are implicated in the development of hypertension and there are differences in these risk factors in urban and rural populations depending on the level of development and epidemiological transition. Aims & Objective:The preesent study was undertaken to estimate the prevalence of hypertension and identify & compare some socio-demographic and lifestyle risk factors associated with hypertension in urban and rural populations of Hapur. Materials and methods: It’s a community based cross-sectional study in which 300 adults each were randomly selected from urban and rural populations of Hapur using modified cluster sampling method. Selected individuals were examined and interviewed using a structured, pre-tested questionnaire. Two Blood Pressure readings were recorded using mercury sphygmomanometer in the sitting position and the mean of two was considered for analysis. Data entry and analysis was done using SPSS for windows version 8.1. Result:Most of the study population belonged to age group of 20–29 yrs (27.5%) followed by 30–39 yrs (24.5%). 41.2% of the study population was constituted by males and the rest 58.8% by females. Majority of the study population belonged to middle class (58%) followed by upper lower class (18%). The prevalence of hypertension was 21% in the present study, which is comparable to the estimates given by World Health Organization (23%). Around 33.7% of the population had blood pressure in the normal range and 45.3% of the population had pre-hypertension. The prevalence of hypertension was 23.7% in the urban areas and 18.3% in the rural areas. This difference was found to be statistically insignificant. Conclusion: The present study identified as risk factors for the development of hypertension – increasing age, sedentary occupation, higher socio-economic status, extra salt intake, family history of hypertension, reduced physical activity, tobacco smoking, smokeless tobacco consumption, alcohol consumption, BMI ≥ 25 and high waist-hip ratio.
高血压是一个重要的全球公共卫生挑战,因为它的高频率和伴随风险的心血管和肾脏疾病。高血压是新时代的流行病,是世界上死亡的主要原因,在残疾调整生命年的原因中排名第三。多种危险因素与高血压的发生有关,根据发展水平和流行病学转变,这些危险因素在城市和农村人口中存在差异。目的和目的:本研究旨在估计哈普尔城市和农村人口中高血压的患病率,并确定和比较与高血压相关的一些社会人口统计学和生活方式风险因素。材料与方法:采用改进的整群抽样方法,从哈普尔市的城乡人口中随机抽取300名成年人,进行基于社区的横断面研究。选定的个人使用结构化的、预先测试的问卷进行检查和访谈。用汞柱血压计在坐姿记录两次血压读数,取两次的平均值进行分析。使用SPSS for windows version 8.1进行数据录入和分析。结果:研究人群以20 ~ 29岁年龄组居多(27.5%),其次为30 ~ 39岁年龄组(24.5%)。41.2%的研究人群为男性,58.8%为女性。大多数研究人群属于中产阶级(58%),其次是中上层阶级(18%)。在本研究中,高血压患病率为21%,与世界卫生组织给出的估计(23%)相当。约33.7%的人口血压在正常范围内,45.3%的人口有高血压前期。城市高血压患病率为23.7%,农村为18.3%。这种差异在统计上是不显著的。结论:本研究确定了高血压发生的危险因素为年龄增加、久坐职业、较高的社会经济地位、额外的盐摄入量、高血压家族史、体力活动减少、吸烟、无烟烟草消费、饮酒、BMI≥25和高腰臀比。

Background and Objectives: Stature estimation plays an important role in establishing individuality of an unidentified dead body or any mutilated part of the body by the medicolegal experts. A strong relationship exists between stature and dimensions of different body parts, particularly bone lengths. In this study, an attempt has been made to derive regression equation to estimate stature from percutaneous length of ulna and tibia among Naga population of Nagaland. Materials and Methods: The study was conducted at Regional Institute of Medical Sciences, Manipur on 100 healthy Medical Students from Nagaland (50 males and 50 females; aged 19-35 years). Stature, length of ulna and tibia on both sides were measured in standard position. Statistical analysis done using SPSS 21. Results: Mean ages of males and females were 23.22 ±3.93 years and 23.12 ±3.34 years, respectively which was not significant. Mean stature of males was 168.12±5.48 cms and females was 157±5.41 cms. Mean ulna and tibial length in males were significantly longer than that of females. A positive correlation between height and both the length of long bones was observed in both the sexes. Conclusion: Distinct sexual dimorphism observed in stature and length of ulna and tibia and also positive linear correlations observed between height and length of ulna and tibia. Linear regression models for stature estimation derived. Stature estimation should be population based as it is racial and gender dependent.
背景与目的:身高估算在法医鉴定身份不明的尸体或残缺部位的个性鉴定中起着重要作用。不同身体部位的身高和尺寸之间存在着密切的关系,尤其是骨骼长度。在这项研究中,我们试图推导回归方程,以估计纳加兰邦那加族的尺骨和胫骨经皮长度。材料和方法:该研究是在曼尼普尔地区医学科学研究所对来自那加兰邦的100名健康医科学生(50名男性和50名女性;年龄19-35岁)。在标准体位测量身高、两侧尺骨、胫骨长度。使用SPSS 21进行统计分析。结果:男女平均年龄分别为23.22±3.93岁和23.12±3.34岁,差异无统计学意义。男性平均身高168.12±5.48 cm,女性平均身高157±5.41 cm。男性尺骨和胫骨的平均长度明显长于女性。在两性中都观察到身高和长骨长度之间的正相关关系。结论:尺骨和胫骨的身高和长度存在明显的性别二态性,尺骨和胫骨的身高和长度也存在正线性相关。推导了身高估计的线性回归模型。身高估计应该以人口为基础,因为它取决于种族和性别。

Background:The prevalence of the Metabolic Syndrome is increasing tremendously due to increase in obesity around the World. Metabolic Syndrome doubles the risk of Atherosclerotic Cardiovascular diseases and approximately four fold increases the risk of developing type II diabetes mellitus. It has been seen that Metabolic Syndrome is on the rising trend especially in post-menopausal women. Metabolic Syndrome is widely increasing especially in the transition phase in every woman’s life from premenopausal to menopausal phase. The aim of this study is to compare presence of metabolic syndrome and its components in premenopausal and post-menopausal women. Material and Methods: The study was conducted in 300 pre-menopausal and 300 postmenopausal women attending Medicine OPD and admitted in ward of Dr. B.R.A.M. Hospital, Raipur C.G. from March 2015 to August 2016.The objective of the study was explained and informed to women and data of each women was recorded in identical pre designed proforma after informed and written consent. Participants were categorized into two groups Pre-menopausal age group and Post-menopausal age group. Investigations including Fasting blood sugar, Lipid Profile and Anthropometric measurements including height, weight, waist circumference (WC) and hip circumference (HC) was recorded. A modified definition by the Adult Treatment Panel III guideline of the National Cholesterol Education Program was used to categorize the subjects according to presence of metabolic syndrome. Results: In the present study the mean age of pre-menopausal and postmenopausal group was 42.8 yrs and 54.5 yrs respectively in a study group of 300 women in each. The mean age of attaining menopause in present study was 46 ± 3.1 yrs. Mean systolic BP in pre-menopausal and post-menopausal study group was 117.13±10.87mmHg and 118.23+13.15mmHg respectively. Mean Diastolic BP in pre-menopausal and postmenopausal study group was 78.55 ± 8.19mmHg and 77.70+9.24mmHg respectively. No significant difference was observed between two groups regarding systolic BP (p=0.265) and diastolic BP. (p=0.234) The mean Waist Circumference (WC) was 78.96 ± 8.84 cms and 80.11±10.82 cms in pre and post menopausal group respectively with no significant difference. Waist Hip Ratio was found to be significantly higher in postmenopausal subjects compare to pre-menopausal subjects.(p=0.001). BMI was was found to be significantly higher in post-menopausal subjects as compared to pre-menopausal subjects.(p=0.003). TG was found to be significantly higher in Postmenopausal subjects compared to pre -menopausal subjects (p<0.0001). HDL was found to be significantly lower in Post-menopausal subjects compared to premenopausal subjects (p=0.071).FBS and PPBS were found to be significantly higher in Postmenopausal subjects as compared to pre-menopausal subjects. Raised FBS levels in post-menopausal subjects was statistically significant (p<0.0001) in the study. The overall prevalence of Metabolic
背景:由于世界范围内肥胖的增加,代谢综合征的患病率正在急剧增加。代谢综合征使患动脉粥样硬化性心血管疾病的风险增加一倍,使患II型糖尿病的风险增加约四倍。已经看到代谢综合征呈上升趋势,特别是绝经后妇女。代谢综合征在每个妇女从绝经前到绝经期的过渡阶段普遍增加。本研究的目的是比较绝经前和绝经后妇女代谢综合征及其组成部分的存在。材料与方法:本研究于2015年3月至2016年8月在Raipur C.G. Dr. B.R.A.M.医院内科门诊就诊的300名绝经前和300名绝经后妇女中进行。向妇女解释和告知研究的目的,并在知情和书面同意后以相同的预先设计的形式记录每位妇女的数据。参与者被分为两组,绝经前年龄组和绝经后年龄组。调查包括空腹血糖、血脂和人体测量,包括身高、体重、腰围和臀围。根据国家胆固醇教育计划成人治疗小组III指南的修改定义,根据代谢综合征的存在对受试者进行分类。结果:在本研究中,绝经前组和绝经后组的平均年龄分别为42.8岁和54.5岁,每组300名妇女。绝经的平均年龄为46±3.1岁。绝经前和绝经后研究组的平均收缩压分别为117.13±10.87mmHg和118.23+13.15mmHg。绝经前和绝经后研究组的平均舒张压分别为78.55±8.19mmHg和77.70+9.24mmHg。两组之间收缩压(p=0.265)和舒张压无显著差异。绝经前组和绝经后组的平均腰围(WC)分别为78.96±8.84 cms和80.11±10.82 cms,差异无统计学意义(p=0.234)。绝经后受试者的腰臀比明显高于绝经前受试者(p=0.001)。发现绝经后受试者的BMI明显高于绝经前受试者(p=0.003)。发现绝经后受试者的TG明显高于绝经前受试者(p<0.0001)。与绝经前受试者相比,绝经后受试者的HDL显著降低(p=0.071)。发现绝经后受试者的FBS和PPBS明显高于绝经前受试者。绝经后受试者FBS水平升高有统计学意义(p<0.0001)。根据NCEP ATP III和IDF标准,代谢综合征的总患病率分别为38%和50.7%。分别在我们的学习。根据NCEP ATP III和IDF标准,绝经后妇女代谢综合征的患病率分别为48.6%和56.8%。根据NCEP ATP III标准,绝经前妇女代谢综合征的患病率为27.4%。按IDF标准44.6%。绝经前组-本研究对象中有1.47%有5种代谢综合征危险因素,15.3%有4种,10.43%有3种,45.9%有2种,26.9%只有一种代谢综合征危险因素。绝经后组有5种危险因素的占10.2%,有4种危险因素的占40.32%,有3种危险因素的占49.4%,有2种危险因素的占50.9%,有1种危险因素的占36.9%。结论:绝经后妇女代谢综合征患病率(48.6%)高于绝经前妇女(27.4%),随年龄增长代谢综合征发病率增高,在40 ~ 60岁达到高峰。在这些女性中,血脂异常和腹部肥胖是代谢综合征最普遍的组成部分。

Laparoscopic cholecystectomy is the standard of care in symptomatic cholelithiasis and it has been associated with complications such as bile duct injury, bleeding, bile leak and residual stones. Postcholecystectomy clip migration is an uncommon complication of laparoscopic cholecystectomy . It was first reported in 1992. We present a case report of a 48 years old lady presenting with right upper abdominal pain fever and vomiting. Patient had undergone an uncomplicated laparoscopic cholecystectomy 13 years earlier. Magnetic resconance cholangiopancreatography revealed non-visualization of lower common bile duct, thick bile and proximal dilatation. Patient was successfully managed with Endoscopic retrograde cholangiopancreatography to remove the stone with along with clip. Long-term follow-up should be done in post-cholecystectomy patients and cystic duct clip migration with eventual biliary complications should be considered as a differential diagnosis in symptomatic post-cholecystectomy patients.
腹腔镜胆囊切除术是治疗症状性胆石症的标准治疗方法,但常伴有胆管损伤、出血、胆漏和残余结石等并发症。胆囊切除术后夹片移位是腹腔镜胆囊切除术中一种罕见的并发症。首次报道是在1992年。我们提出一个病例报告,48岁的妇女表现为右上腹部疼痛,发烧和呕吐。患者13年前曾做过简单的腹腔镜胆囊切除术。磁共振胆管造影显示胆总管下段未见,胆厚及近端扩张。患者成功地通过内镜逆行胆管造影,连同夹子取出结石。胆囊切除术后患者应进行长期随访,对于有症状的胆囊切除术后患者,应考虑将胆囊管夹移位最终导致胆道并发症作为鉴别诊断。

Aim Of The Study: To assess the hematological profile of patients with chronic liver disease and their correlation in patients with GI Bleed. Materials And Methods: To assess the hematological abnormalities in chronic liver disease, a cross sectional analytical study was conducted All patients taken up for the study were evaluated in detail. Oral consent was obtained for clinical examination and lab investigations. Written consent was obtained for procedures such paracentesis, Upper GI endoscopy and viral marker studies. Inclusion Criteria 1. All patients with liver disease whose symptoms and signs persists for more than 6 months 2. Alcoholic cirrhosis, post-necrotic cirrhosis, metabolic causes of liver diseases were taken up for the study Exclusion Criteria 1. Patients with underlying malignancy or known primary hepatocellular carcinoma were excluded 2. Patients with primary coagulation disorder or primary abnormalities of haemostatic function were excluded. 3. Acute hepatic failure was excluded 4. Patients with preexisting anemia due to other causes were excluded. 5. Patients suffering from end stage medical diseases like COPD, Coronary artery disease, cardiac failure, CKD were excluded Observation & Data Analysis: A descriptive study to assess the hematological abnormalities in chronic liver disease was conducted at Department of Digestive Health and diseases, Kilpauk medical college , Chennai from August 2016 to January 2017. 50 patients with chronic liver disease were taken for the study; this included 43 males (86%) and 7 females (14 %). The age range was from 24 to 70. The average age of the patients in the study was 48 yrs. 70 % of the patients were between 40 and 60 years. 52% of the patients had alcoholic cirrhosis were males. The aetiology of chronic liver disease could not be determined in 24 % of cases but all of them had clinical and radiological features of cirrhosis. 6 patients had Hepatitis B and 2 had Hepatitis C; all these 8 patients had cirrhosis. Autoimmune hepatitis and cirrhosis were present in 2 females Results: 50 % of the patients had thrombocytopenia (<1 lakh). Of the 13 patients who had an upper GI bleed 3 patients had normal platelet counts and the rest had counts below 1 lakh. The average platelet count of patients who experienced an upper GI bleed was 92000 vs. 1.2 lakh in patients without a GI bleed. The bleeding time was prolonged only in 6 patients with thrombocytopenia indicating BT as an insensitive test. 36 patients had a prolonged INR. Among the 13 patients with upper GI bleed 9 had prolonged INR; indicating other factors play a role in GI bleed Conclusions: Many conclusive results regarding the hematological abnormalities in chronic liver disease were obtained with this limited study involving 50 patients with cirrhosis ⇒ 50 % of patients had thrombocytopenia. ⇒ The average platelet count of patients with an upper GI bleed was 92000 compared to 1.2 lakh to those without an upper GI bleed; suggesting other fa
研究目的:评估慢性肝病患者的血液学特征及其与胃肠道出血患者的相关性。材料与方法:为了评估慢性肝病的血液学异常,我们进行了一项横断面分析研究,对所有纳入研究的患者进行了详细评估。获得临床检查和实验室调查的口头同意。对穿刺、上消化道内窥镜检查和病毒标记物研究等程序获得书面同意。纳入标准所有症状和体征持续6个月以上的肝病患者2。酒精性肝硬化、坏死后肝硬化、肝脏疾病的代谢性原因被纳入研究排除标准1。排除有潜在恶性肿瘤或已知原发性肝细胞癌的患者。排除原发凝血障碍或原发止血功能异常的患者。3.排除急性肝衰竭4。排除其他原因导致的既往贫血患者。5. 排除COPD、冠心病、心力衰竭、CKD等终末期内科疾病患者。观察与数据分析:2016年8月至2017年1月,在金奈Kilpauk医学院消化健康与疾病科进行了一项描述性研究,评估慢性肝病患者的血清学异常。研究对象为50例慢性肝病患者;其中包括43名男性(86%)和7名女性(14%)。年龄范围从24岁到70岁。研究中患者的平均年龄为48岁。70%的患者年龄在40 - 60岁之间。52%的酒精性肝硬化患者为男性。24%的慢性肝病病因不明,但均具有肝硬化的临床和影像学特征。乙型肝炎6例,丙型肝炎2例;8例患者均有肝硬化。2例女性存在自身免疫性肝炎和肝硬化。结果:50%的患者有血小板减少(< 10万)。13例上消化道出血患者中,3例血小板计数正常,其余血小板计数低于10万。经历过上消化道出血的患者平均血小板计数为92000,而没有胃肠道出血的患者平均血小板计数为12万。只有6例血小板减少患者出血时间延长,表明BT是一种不敏感的试验。36例患者INR延长。13例上消化道出血患者中9例有延长的INR;结论:在这项涉及50例肝硬化患者的有限研究中,获得了许多关于慢性肝病血液学异常的结论性结果。50%的患者有血小板减少。⇒上消化道出血患者的平均血小板计数为92000,而没有上消化道出血的患者的平均血小板计数为12万;提示其他因素如功能性血小板缺陷也可能起作用。这些需要通过血小板功能研究来证实。⇒只有12%的血小板减少症患者出血时间延长,这表明BT是血小板数量和功能的不敏感试验。72%的患者PT-INR升高。然而,只有25%的PT-INR延长患者有上消化道出血,这表明其他因素,如重新平衡的止血系统在起作用,然而,这项关于慢性肝病血液学异常的研究DOI: 10.9790/0853-1606143844 www.iosrjournals.org 39 | Page需要更广泛的研究来证实。这一结果强调了这样一个事实,即在纠正肝硬化患者的凝血功能障碍时,必须治疗患者的临床状态而不是实验室值。从这项研究中我们可以得出结论,各种血液学改变在肝硬化患者中很常见,需要及早发现和纠正,以降低发病率和死亡率。

Persistent Enlarged Thymus in an Adult Human Cadaver 成人尸体胸腺持续增大
Pub Date : 2017-08-01 DOI: 10.9790/0853-0143435
S. Shevade, J. Kulkarni, Neelesh Kanaskar, V. Paranjape
Thymus is an irregular bilobed gland situated in the superior and anterior mediastinum. It lies above the pericardium, aortic arch, left brachiocephalic vein, and trachea. Superiorly thymus may extend to the lower pole of thyroid gland and inferiorly up to the diaphragm.. Each thymic lobe is covered by a fibrous capsule. It weighs about 10 to 15 gms at birth and progressively increases in size and weighs about 20 to 30 gms at puberty. There after it undergoes involution and is converted into a fibrofatty mass. Thymus does show morphological variations in the gross anatomy. It may be persistent in the adult. This fact is clinically important for radiologists to make a differential diagnosis in case of a mediastinal mass. A thorough knowledge of the embryology and anatomy of the thymus, normal variations and ectopic locations of thymus and its dynamic changes is necessary before doing any invasive procedure.
胸腺是位于上纵隔和前纵隔的不规则双叶腺。它位于心包、主动脉弓、左头臂静脉和气管上方。上胸腺可以延伸到甲状腺的下极,向下延伸到横膈膜。每个胸腺叶被纤维囊覆盖。它出生时重约10至15克,逐渐增大,青春期重约20至30克。之后,它经历了退化并转化为纤维脂肪团块。胸腺在大体解剖上确实表现出形态上的变异。它可能在成人中持续存在。这一事实对放射科医生在纵膈肿块的情况下进行鉴别诊断具有重要的临床意义。在进行任何侵入性手术之前,对胸腺的胚胎学和解剖学,胸腺的正常变异和异位位置及其动态变化的全面了解是必要的。
