MR Imaging in Eclampsia

Background : The aim of this study is to determine the distribution and nature of Cranial MRI findings in eclamptic patients, and to correlate them with clinical and laboratory data. Materials and Methods : This study was conducted in the Department of Obstetrics and Gynecology in Sri Ramachandra Institute of Higher Education and Research. A total number of 35 Eclamptic patients were included in this study and they were analyzed retrospectively. Laboratory parameters, Blood Pressure and Cranial MRI was performed for all and the same were analyzed statistically. Results : Out of 35 Eclamptic patients, MR Imaging was normal in 6 patients. Among the 29 patients with abnormal MRI, Cortical-subcortical Lesion, appeared iso/hypo-intense in T-1 weighted images and hyper intense in T-2 weighted images. In most of the patients, occipital lobe was involved followed by involvement of other lobes such as Parietal, Frontal, Temporal, Basal Ganglia and Cerebellum. When patients with and without positive MRI findings were compared regarding clinical features such as Headache, Blurred Vision, Nausea and Vomiting, Epigastric Pain, Loss of Consciousness, Reduced Urine Output there was no statistically significant difference between the two groups. Similarly, there was no statistical difference in mean arterial pressures between MRI positive and MRI negative patients (p=0.218) however, it was found that those with MR imaging positive features had a higher Blood Pressure than those with MRI negative findings. Among the laboratory parameters, in the patients with abnormal MRI findings Fibrinogen was found to be significantly low than those with normal MRI findings (p=0.0002).

A rare case of sulcal hemorrhage after ischemic stroke � A case report

Atraumatic Non-aneurysmal sulcal subarachnoid hemorrhage is very rare. Sulcal subarachnoid hemorrhage (sSAH) is characterized by isolated bleeding in one or a few adjacent sulci. Central sulcus hemorrhage is a rare imaging finding. There are many causes for sSAH. In older patients, sSAH is due to Cerebral Amyloid Angiopathy (CAA), while in younger patients, reversible cerebral vasoconstriction syndrome (RCVS) is the most frequent etiology. Imaging studies help in the evaluation of sSAH. We report a rare case of an isolated central sulcus hemorrhage on computed tomography. sSAH usually occur on the side with acute ischemic stroke, and it is unusual for sSAH to occur on the opposite side of the infarct territory, but in our case sSAH occurred on opposite side, but after a gap of 3 years.

The patient was subsequently diagnosed and treated as BHS.

Five-year Contraceptive Use of 52-mg Levonorgestrel Releasing Intrauterine System in Young Women, Menstrual Patterns, and New Contraceptive Choice / Cinco anos de uso contraceptivo do sistema intrauterino liberador de levonorgestrel 52 mg em mulheres jovens, padrões menstruais e nova escolha contraceptiva

Abstract Objective To evaluate the continuation rates of the 52-mg levonorgestrel-releasing intrauterine system (LNG-IUS) during the first 5 years of use, reasons for its discontinuation, bleeding patterns, and new contraceptive choice after the 5th year, in adolescents and young women. Methods The present study was a 5-year prospective cohort conducted in a Family Planning Service of a tertiary hospital in Brazil. We selected 100 healthy women between 15 and 24 years old who used 52-mg LNG-IUS for contraception. The clinical follow-up of these women took place from June 2017 to December 2022. The study evaluated the continuation rates of the method, reasons for its discontinuation, bleeding patterns, and new contraceptive choice after the 5th year. Continuous data were reported as mean ± standard deviation (SD) and range (minimum-maximum). Categorical variables were described as percentages. Results The continuation rates of LNG-IUS were 89.1% (82/92), 82.9% (72/87), 75.3% (64/85), 70.5% (60/85), and 64.2% (54/84) in the 1st, 2nd, 3rd, 4th, and 5th years of use, respectively. The main reason for discontinuation was acne (11/30). Amenorrhea rates were 50, 54.1, 39, 35.7, and 51.8% at 12, 24, 36, 48, and 60 months, respectively. All patients who completed the study and needed contraception after the 5th year opted for long-acting contraceptive methods (LARC). Conclusion The LNG-IUS showed high continuation rates in adolescents and young women in the first 5 years of use. Most patients who completed the study chose a LARC method after the 5th year.

Research progress of intelligent reversible drug delivery system / 药学学报

In the research on cancer theranostics, most environment-sensitive drug delivery systems can only achieve unidirectional and irreversible responsive changes under pathological conditions, thereby improving the targeting effect and drug release performance of the delivery system. However, such irreversible changes pose potential safety hazards when the dynamically distributed delivery system returns to the blood circulation or transports to the normal physiological environment. Intelligent reversible drug delivery systems can respond to normal physiological and pathological microenvironments to achieve bidirectional and reversible structural changes. This feature will help to precisely control the drug release of the delivery system, prolong the blood circulation time, improve the targeting efficiency, and avoid the potential safety hazards of the irreversible drug delivery system. In this review, we describe the research progress of intelligent reversible drug delivery system from two main aspects: controlled drug release and prolonged blood circulation time/enhanced cellular internalization of drug.

Bilayer hydrogel dressing with lysozyme-enhanced photothermal therapy for biofilm eradication and accelerated chronic wound repair

Biofilms are closely associated with the tough healing and dysfunctional inflammation of chronic wounds. Photothermal therapy (PTT) emerged as a suitable alternative which could destroy the structure of biofilms with local physical heat. However, the efficacy of PTT is limited because the excessive hyperthermia could damage surrounding tissues. Besides, the difficult reserve and delivery of photothermal agents makes PTT hard to eradicate biofilms as expectation. Herein, we present a GelMA-EGF/Gelatin-MPDA-LZM bilayer hydrogel dressing to perform lysozyme-enhanced PTT for biofilms eradication and a further acceleration to the repair of chronic wounds. Gelatin was used as inner layer hydrogel to reserve lysozyme (LZM) loaded mesoporous polydopamine (MPDA) (MPDA-LZM) nanoparticles, which could rapidly liquefy while temperature rising so as to achieve a bulk release of nanoparticles. MPDA-LZM nanoparticles serve as photothermal agents with antibacterial capability, could deeply penetrate and destroy biofilms. In addition, the outer layer hydrogel consisted of gelatin methacryloyl (GelMA) and epidermal growth factor (EGF) promoted wound healing and tissue regeneration. It displayed remarkable efficacy on alleviating infection and accelerating wound healing in vivo. Overall, the innovative therapeutic strategy we came up with has significant effect on biofilms eradication and shows promising application in promoting the repair of clinical chronic wounds.

DELAYED PRESENTATION OF POSTERIOR REVERSIBLE ENCEPHALOPATHY SYNDROME IN POSTPARTUM PERIOD

Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurological entity which presents with diverse neurological symptoms ranging from headache, seizure, visual symptoms with altered consciousness and focal signs. The hallmark of this condition is its reversibility. The etio- pathogenesis is attributed to vasogenic cerebral oedema seen in occipital and parietal lobes of brain. We hereby present this case of a multiparous lady presenting with altered sensorium postpartum. Characteristic findings on imaging helped us to form the diagnosis of PRES in this patient

Super refractory status epilepticus in a parturient with preeclampsia undergoing cesarean delivery under spinal anesthesia

Super refractory status epilepticus (SRSE) is a rare but serious neurological emergency. This case report aims to highlight the challenges faced during the diagnosis and management of SRSE in a 36-year-old preeclamptic patient taken for cesarean delivery under spinal anesthesia. The patient developed a seizure episode minutes after administration of intrathecal bupivacaine, necessitating administration of general anesthesia. Postoperatively, SRSE developed which did not respond to multiple anti-epileptics and thiopentone sodium infusion. Although the clinical picture and magnetic resonance imaging findings supported the diagnosis of posterior reversible encephalopathy syndrome, the role of intrathecal bupivacaine in causing SRSE could not be ruled out due to the temporal association of events. The patient had a prolonged and complicated hospital stay and despite a multimodal approach to the treatment, suffered neurological sequelae.

Posterior reversible encephalopathy syndrome in pregnancy: A case series of 5 cases

Posterior reversible encephalopathy syndrome (PRES) is a rare clinic-radiological syndrome associated with acute changes in blood pressure during pregnancy. It is characterized symptomatically by headache, seizures, altered mental status, and visual blurring. Radiological changes are white matter vasogenic edema affecting the occipital and parietal lobes of the brain. It is being increasingly recognized due to increased institutional deliveries and advances in imaging particularly magnetic resonance imaging (MRI). Despite the increasing detection, the prediction of PRES and patient factors affecting susceptibility is still not clear. Hence, we conducted a retrospective study to analyze the factors associated with PRES at our tertiary care center.

Dural arteriovenousfistula presenting as reversible dementia

DAVF is an abnormal connection between arteries and veins, where supply is mainly through branches arising from the external carotid artery. A 30 years old male had multiple episodes of seizures and progressive behavioral and cognitive decline, inattentionand disorientation to time, place and person, along with ptosis and ophthalmoplegia in the right eye. DSA provided a definitive diagnosis of hypervascular Dural AV fistula at the right transverse sigmoid junction with significant cortical venous hypertension. Through femoral access, both underwent transarterial embolization through the Middle Meningeal branch of the right external carotid artery using onyx, resulting in complete occlusion of fistula and resolution of venous hypertension. Post embolisation,cognitive function assessment revealed increased attention span and improved orientation with time,place and person. Thus, DAVF can be one of the rare but reversible causes of dementia. Early diagnosis and treatment may help to dramatically improve patients� clinical condition and minimize long-term disability

Cardiac Tamponade an Unusual Presentation of SLE — A Case Report

Systemic Lupus Erythematous (SLE) is an immune mediated disease, having variety of clinical manifestations but Cardiac Tamponade is rare as initial presentation. We are presenting an unusual case of cardiac tamponade as initial manifestation of SLE, which was also associated with Mitral Valve Vegetation, Posterior Reversible Encephalopathy Syndrome (PRESS); successfully responded to Pericardiocentesis, Steroids and Antimalarials

Spontaneous intracranial hypotension associated with posterior reversible encephalopathy syndrome

Spontaneous intracranial hypotension (SIH) is usually due to cerebrospinal fluid (CSF) leak, resulting in loss of CSF volume. Posterior reversible encephalopathy syndrome (PRES) is the inability of the posterior circulation of the brain to autoregulate in response to significant variation in blood pressure.Altered perfusion with associated blood-brain barrier disruption may lead to vasogenic edema, usually without infarction, commonly in the parieto-occipital regions. Magnetic resonance (MR) imaging of the brain and spine and cerebral MR venography are essential tools for diagnosing clinically suspected SIH and PRES. We present 18-year-young gentleman with clinical and radiological signs of SIH, which later evolved toward PRES.

Manejo farmacológico del sangrado irregular no menstrual asociado al uso de implantes anticonceptivos subdérmicos / Pharmacological management of irregular non-menstrual bleeding associated with the use of subdermal contraceptive implants

El spottingo sangrado irregular no menstrual es uno de los principales efectos secundarios de los implantes anticonceptivos, situación que se recomienda discutir con la usuaria previo a la colocación, para evitar falsas expectativas o temores que lleven a la extracción temprana del dispositivo. A propósito de una paciente sin antecedentes relevantes que consultó al centro de salud por spotting desde la colocación del implante cuatro meses antes, decidimos revisar la evidencia sobre la efectividad de los distintos esquemas farmacológicos disponibles para el manejo de este evento adverso. Luego de realizar una búsqueda bibliográfica concluimos que, si bien existe sustento para indicar algunos de los esquemas farmacológicos, este es aún débil y son necesarios estudios clínicos adicionales que brinden evidencia sólida sobre qué esquema en particular utilizar, evaluando sus riesgos y beneficios. (AU)

Spotting or irregular non-menstrual bleeding is one of the main side effects of contraceptive implants, a situation that health professionals must discuss with the user prior to its placement in order to avoid false expectations or fears that lead to early removal of the implant. Regarding a patient with no relevant history who consulted the health center due to spotting four months after implant placement, we decided to review the evidence onthe effectiveness on different pharmacological schemes available for the management of this adverse event. After performing a literature search, we concluded that, although there is support for indicating some of the pharmacological schemes, this is still weak, and further clinical studies are needed to provide solid evidence on which particular scheme touse, assessing its risks and benefits.

Potential of LARC to recover loss in satisfied demand for modern contraception after the COVID-19 pandemic: a case scenario analysis of Brazil and Mexico / Potencial de los anticonceptivos de acción prolongada para recuperar las pérdidas en la demanda satisfecha de anticonceptivos modernos después de la pandemia de COVID-19: análisis de escenarios en Brasil y México / Potencial dos métodos contraceptivos reversíveis de longa duração para recuperar a perda de demanda por planejamento familiar atendida por métodos contraceptivos modernos após a pandemia de COVID-19: análise de cenários do Brasil e do México

ABSTRACT Objectives. To estimate inequalities in demand for family planning satisfied with modern methods among women in Latin America and the Caribbean, with an emphasis on Brazil and Mexico, and to calculate the scenario for recovery of modern contraceptive coverage by expanding access to long-acting contraceptives (LARC) after the COVID-19 pandemic. Methods. National health surveys from 2006 to 2018 were used to estimate the demand for family planning satisfied with modern methods and how it was affected by the COVID-19 pandemic. The scenario included three variables: coverage, health outcomes, and costs. Considering coverage, United Nations Population Fund data were used to estimate the impact of COVID-19 on access to contraception in Latin America and the Caribbean. Health outcomes were assessed with the Impact 2 tool. Direct investment was used to evaluate cost-effectiveness. Results. Substantial inequalities were found in the use of modern contraceptive methods before the pandemic. We showed the potential cost-effectiveness of avoiding maternal deaths by introducing LARCs. Conclusions. In the scenario predicted for Brazil and Mexico, the costs of modern family planning and averted disability-adjusted life years are modest. Governments in Latin America and the Caribbean should consider promoting LARCs as a highly efficient and cost-effective intervention.

Os governos da América Latina e do Caribe devem considerar a promoção dos LARC como uma intervenção altamente eficiente e custo-efetiva.

Imaging manifestations of central nervous system complications after heart transplantation / 器官移植

Heart transplantation is the main treatment of end-stage heart failure. With the advancement of heart transplantation and rational use of postoperative immunosuppressants, the survival rate of recipients has been gradually enhanced. However, a variety of central nervous system complications may still occur following heart transplantation, including immunosuppressant-associated neurotoxicity, epilepsy, stroke, encephalopathy, central nervous system infection and de novo malignant tumors in the central nervous system. These complications will severely affect the quality of life of heart transplant recipients. Consequently, prompt imaging diagnosis plays a significant role in the prevention and treatment of central nervous system complications. In this article, main imaging manifestations of central nervous system complications after heart transplantation were reviewed, aiming to provide reference for prompt diagnosis and differential diagnosis of complications, guide clinical treatment and management, and improve the long-term prognosis of the recipients.

Prevalence and determinants of long‑acting reversible contraception initiation among teenage mothers in a tertiary hospital / Philippine Journal of Obstetrics and Gynecology

Background@#According to the WHO, about 16 million girls at the age of 15–19 years give birth each year. In the Philippines, 600 live births a day are registered under teenage mothers. At Mariano Marcos Memorial Hospital and Medical Center, 12% of all obstetric admissions yearly are teenagers. The American College of Obstetricians and Gynecologists recommends long‑acting reversible contraception (LARCs), in the form of intrauterine device and progestin subdermal implant as pregnancy prevention options for young mothers. The objective of the study was to identify the prevalence and determinants of long‑acting reversible contraception (LARC) initiation among teenage mothers in Mariano Marcos Memorial Hospital and Medical Center.@*Methodology@#Prospective observational study: A self‑administered questionnaire was given to the respondents wherein they ranked determinants involved in their selection of a contraceptive method on a scale of 1–4 (1 being the most important, and 4, the least important.@*Results@#A total of 162 teenage mothers participated in the study. Majority of the respondents were 17–18 years old, enrolled up to high school, single, unemployed, and primiparas. Eighty‑seven percentage of all teenage mothers admitted at Mariano Marcos Memorial Hospital and Medical Center from December 2020 to December 2021 used long‑active reversible contraception. Ranked from most (1) to least (4) important, the respondents considered: (1) Effectivity, (2) Long duration, (3) Family influence, and (4) Peer influence as their determinants for initiating LARC method. The high effectiveness and long duration of LARC were the primary reasons for initiation, while the least factors they considered were that of peer and family influence.
