Background and Purpose-To provide evidence whether mechanical thrombectomy with stent-retrievers in the treatment of acute ischemic stroke causes intimal damage. Methods-This study analyzed thrombi retrieved by mechanical thrombectomy from cerebral arteries in 48 consecutive patients with acute ischemic stroke for the presence of endothelial cells using CD34 antibodies. Results-Of 48 thrombi analyzed, CD34-positive cells were absent in 20, present as isolated cells in 21, and found in clusters in 7 thrombi. We did not find any subendothelial vessel wall structures. Conclusions-Our findings suggest that mechanical thrombectomy with stent-retrievers does not cause relevant intimal damage in acute ischemic stroke treatment. © 2013 American Heart Association, Inc.

Background: Primary ovarian pregnancy is one of the rarest forms of ectopic pregnancy having incidence of 1/7000-1/40,000 in live births and 0.5-3% of all ectopic gestations. Intrauterine contraceptive device (IUCD), salpingitis, infertility, and assisted reproductive techniques are the important risk factors. Approximately, 75% terminate in first trimester and are often misdiagnosed as corpus luteum haemorrhage. Preoperative diagnosis by ultrasonography (USG) in early pregnancy can help in conservative medical/ surgical management. Objective: The aim of the present study was to find the incidence, risk factors, role of USG in pre-operative diagnosis, feasibility of conservative management with medical method or minimal invasive surgery in developing countries like India. Materials and Methods: We did a retrospective cross-sectional study of ovarian pregnancies managed at Government Medical College and Hospital Chandigarh between July 2000 to July 2010. We analyzed the incidence, risk factors, clinical presentation, management of ovarian pregnancy, and reviewed the literature. Results: Incidence of ovarian pregnancy was 4.9% of all ectopic pregnancies (14/523). Thirteen (93%) patients presented in first trimester with acute pain abdomen and of these ten patients had bleeding per vaginum. One (7%) patient referred from peripheral hospital at term gestation with ultrasonographic diagnosis of breech presention with plecenta previa. Pre-operative diagnosis was made only in two cases (11%). All cases were managed by laparotomy. Excision of the sac with conservation of the ovary was done in eleven cases (78%) and oophorectomy was done in two cases (14%). Conclusion: Incidence of ovarian pregnancy is on the rise. Although ultrasonography can detect ovarian gestations in unruptured cases but cannot easily differentiate ovarian from other tubal gestation in ruptured state. Medical management is usually not feasible it most of the patients present in ruptured state. Conservative surgical approach is the management of choice. © 2014, Research and Clinical Center for Infertitlity. All rights reserved. Source

Dyschromatosis universalis hereditaria is an infrequently occurring genodermatosis with peculiar pigmentary changes, consisting of varying sized, intermingled hyperpigmented and hypopigmented macules that give an overall impression of mottling. We hereby report a case of dyschromatosis universalis hereditaria in a young female with a family history of the disorder. Source

Background and Objective: The nervous system is the most frequent and serious targets of human immunodeficiency virus (HIV) infection. In spite of a wide prevalence of neurological manifestations in HIV there are not many studies to look into it, especially from this part of the world. We investigated various neurological manifestations of HIV and their association with CD4 and CD8 counts at the time of presentation. Materials and Methods: All HIV-infected patients who presented to 750 bedded teaching hospital in North India were subjected to thorough neurological and neuropsychological evaluation. Wherever indicated, neuroimaging, cerebrospinal fluid study, electromyography, and nerve-conduction studies were performed to confirm the diagnosis. CD4 and CD8 counts were calculated. Results: A total of 416 HIV-positive patients were seen. Of them 269 were males. A total of 312 neurological events were identified in 268 patients having evidence of neurological involvement. HIV-associated dementia (HAD) was the most common cause of morbidity (33.65%), followed by CNS infections (21.63%). Most common CNS infection was tuberculosis (65.56%). CD4 counts in CNS infections and HAD were 64.8/ml and 83.52/ml, respectively. Most of the patients in our study had low scores on MMSE (22.32). Conclusions: Even in the absence of overt neurological disease, subclinical involvement in the form of subtle cognitive and motor decline is found to occur with greater frequency. Most of these patients have lower CD4 and CD8 counts, thus substantiating the proposition that neuroAIDS is a late manifestation. Significant correlation exists between CD4 counts and type of neurological manifestation. We concluded that neuropsychological assessment should be mandatory for all HIV-positive patients. Source

Background: Use of opioids for perioperative analgesia is associated with sedation, respiratory depression and postoperative nausea and vomiting. N-methyl-D-aspartate receptor antagonist such as ketamine has both analgesic and antihyperalgesic properties. We studied the effect of intraoperative infusion of low-dose ketamine on postoperative analgesia and its management with opioids. Materials and Methods: A total of 80 patients scheduled for open cholecystectomy under general anesthesia were randomly allocated into two equal groups in a randomized double-blinded way. The general anesthetic technique was standardized in both groups. Group K patients (n = 40) received bolus of ketamine 0.2 mg/kg intravenously followed by an infusion of 0.1 mg/kg/h before skin incision, which was continued up to the end of surgery. Similar volume of saline was infused in Group C (n = 40). The pain score at different intervals and cumulative morphine consumption over 24 h was observed. Secondary outcomes such as hemodynamic parameters, patient satisfaction score and incidences of side effects were also recorded. Results: Intraoperative infusion of low-dose ketamine resulted in effective analgesia in first 6 h of the postoperative period, which was evident from reduced pain scores and reduced opioid requirements (P = 0.001). The incidence of side effects and patient satisfaction were similar in both groups. Conclusion: Intraoperative low-dose ketamine infusion provides good postoperative analgesia while reducing need of opioid analgesics, which must be considered for better management of postoperative analgesia.
