Objective. Persistence of hyperparathyroidism (HPT) after renal transplantation leads to undesirable outcomes such as increase in cardiovascular events, graft dysfunction, and increased mortality. Options for therapy include medical management with calcimimetic or operative management. The present study was undertaken to evaluate the natural history of HPT after renal transplantation and to determine risk factors for persistent HPT in the era of calcimimetic. Design. The study is a retrospective review of data from 74 consecutive patients who underwent renal transplantation at our institution from April 2011 to November 2019. Methods. The natural history of HPT after renal transplantation and associations between intact parathyroid hormone (PTH) level after transplantation and clinical variables such as age, sex, duration of pretransplant dialysis, and use of calcimimetic before transplantation were evaluated. Results. Intact PTH decreased after renal transplantation in most of the patients without receiving parathyroidectomy. Known risk factors of persistent HPT did not associate with intact PTH level after renal transplantation in patients who had been receiving calcimimetic before transplantation. Conclusion. In conclusion, we have found that HPT after renal transplantation could be managed successfully by medical treatments. When predicting the prognosis of HPT after transplantation, pretransplant use of calcimimetic should be taken into consideration.

Abstract Hemorrhagic stroke (HS) is a major cause of death and disability worldwide, despite being less common, it presents more aggressively and leads to more severe sequelae than ischemic stroke. There are two types of HS: Intracerebral Hemorrhage (ICH) and Subarachnoid Hemorrhage (SAH), differing not only in the site of bleeding, but also in the mechanisms responsible for acute and subacute symptoms. This is a systematic review of databases in search of works of the last five years relating to the comprehension of both kinds of HS. Sixty two articles composed the direct findings of the recent literature and were further characterized to construct the pathophysiology in the order of events. The road to the understanding of the spontaneous HS pathophysiology is far from complete. Our findings show specific and individual results relating to the natural history of the disease of ICH and SAH, presenting common and different risk factors, distinct and similar clinical manifestations at onset or later days to weeks, and possible complications for both.

Introduction: Ectopic pregnancy is a major clinical problem in gynaecology because it is often difficult to diagnose as the patient present in different ways. An accurate history taking and physical examination is considered to be most important in the diagnosis of ectopic pregnancy. There are two treatment options, medical or surgical. Surgical treatment is the fastest treatment for ectopic pregnancy though surgical management decreased from approximately 90% to 65%1. Surgery may be the only treatment option if there is internal bleeding. In the medical treatment group, 15% of cases were categorized as failures and required surgery1.Objectives: This study was conducted in the department of obst and Gynae of Dhaka Medical College Hospital from January 2005 to June 2005 in an attempt to find out the risk factors of ectopic pregnancy, the way of presentation and to analyze the operative treatment of ectopic pregnancy.Materials and Methods: A total 50 consecutive patients who were clinically suspicious of ectopic pregnancy were included in this study between January 2005 to June 2005. Patients who were clinically suspicious of EP and also supported by positive urinary pregnancy tests, beta hCG and no intrauterine gestational sac in ultrasonography were included in this study. Detailed discussion about the study was done with the patient and then informed verbal consent was taken from them. Detailed history about patient profile, presenting symptoms, any risk factors and clinical examination done and the findings were recorded in the predesigned data collection sheet. Data was expressed in terms of frequencies and percentagesResults: Most of the patients were in the age group of 20-30 years and 38% of low parity (para- 1).Previous miscarriage, infertility,IUCD users and PID identified as the risk factors of ectopic pregnancy— 42% patients had history of previous abortion or MR, period of infertility 22%, pelvic infection 12%, IUCD users 16%. In this study acute abdominal pain after a short period of amenorrhoea was found to be the main symptoms in ectopic pregnancy—100% patients were presented with lower abdominal pain, 70% with period of amenorrhea and 50% patients with per vaginal bleeding. All the patients were presented with acute condition and were surgically managed fastest treatment. At the time of operation 84% of ectopic tubal pregnancy were found ruptured, 10% were tubal abortion and 4% unruptured. Sites of ectopic pregnancy were ampullary 50%, isthmic 20%, fimbrial 10%.Conclusion: Most of the patient presented in acute condition with the classical features of ruptured ectopic pregnancy. Near half of the patient were in younger age group (26 – 30 years) having risk factors like history of previous abortion/MR 42%, infertility 22% use of IUCD 16%, PID 12%. More then three forth( 84%) of cases were diagnosed as ruptured ectopic during operation. Operative management was done on the basis of site of ectopic and parity of the womanBangladesh J Obstet Gynaecol, 2013; Vol. 28(1) : 9-14

A study of the natural history of sickle hemoglobinopathies was begun in March 1979. By August 1987, a total of 2824 patients <20 years of age were enrolled. There have been 14 670 person-years of followup. Seventy-three deaths have occurred. Most of the deaths were in patients with hemoglobin SS. The peak incidence of death was between 1 and 3 years of age, and the major cause in these young patients was infection. Cerebrovascular accidents and traumatic events exceeded infections as a cause of death in patients > 10 years of age. There was limited success in identifying risk factors for death. Comparison of this study's overall mortality of 2.6% (0.5 deaths per 100 person-years) with previous reports indicates improvement of survival in US patients <20 years of age with sickle hemoglobinopathies. This improvement is most likely due to parental education and counseling about the illness and the early institution of antibotics in suspected infections.

Aim. It is known that different stages of type 2 diabetes represent distinct pathophysiological changes, but how the spectrum of risk factors varies at different stages is not yet clarified. Hence, the aim of this study was to compare the effect of different metabolic variables on the natural history of type 2 diabetes. Methods. A total of 5,213 nondiabetic (normal glucose tolerance (NGT) and prediabetes) Chinese older than 40 years participated this prospective cohort study, and 4,577 completed the 3-year follow-up. Glycemic status was determined by standard oral glucose tolerance test both at enrollment and follow-up visit. Predictors for conversion in glycemic status were studied in a corresponding subcohort using the multiple logistic regression analysis. Results. The incidence of prediabetes and diabetes of the cohort was 93.6 and 42.2 per 1,000 person-years, respectively. After a 3-year follow-up, 33.1% of prediabetes patients regressed to NGT. The predictive weight of body mass index (BMI), serum triglyceride, total cholesterol, and systolic blood pressure in different paths of conversions among diabetes, prediabetes, and NGT differed. Specifically, BMI was the strongest predictor for regression from prediabetes to NGT, while triglyceride was most prominent for onset of diabetes. One SD increase in serum triglyceride was associated with a 1.29- (95% CI 1.10–1.52; P=0.002) or 1.12- (95% CI 1.01–1.27; P=0.039) fold higher risk of diabetes for individuals with NGT or prediabetes, respectively. Conclusion. Risk factors for different stages of diabetes differed, suggesting personalized preventive strategies for individuals with different basal glycemic statuses.

Abstract A multi-institutional study, Pathobiological Determinants of Atherosclerosis in Youth (PDAY), was initiated to document the natural history of atherosclerosis, its relationship to risk factors, and the pathobiology of lesion development in young subjects. Pathology laboratories in nine centers collected arteries and tissues from > 2000 persons, ages 15-34 years, whose deaths were attributed to homicides, accidents, or suicides. Arteries were evaluated for lesions, and risk factors were analyzed in a central laboratory. Postmortem risk factors include serum lipoproteins, serum thiocyanate (smoking), glycohemoglobin (diabetes), thickness of panniculus adiposus (obesity), changes in small renal arteries (hypertension), and apoprotein isoforms. This PDAY study documents the development of atherosclerosis at an early age and shows that the recognized risk factors for coronary heart disease are associated with lesion development in the arteries of these young subjects. The findings provide a strong justification for reducing risk factors in young persons.
