Mirror movements in progressive hemifacial atrophy

Mirror movements are simultaneous, involuntary, identical movements occurring during contralateral voluntary movements. These movements are considered as soft neurologic signs seen uncommonly in clinical practice. The mirror movements are described in various neurological disorders which include parkinsonism, cranio veretebral junction anamolies, and hemiplegic cerebral palsy. These movements are intriguing and can pose significant disability. However, no such observation regarding mirror movements in progressive hemifacial atrophy have been reported previously. We are reporting a teenage girl suffering from progressive hemifacial atrophy and epilepsy with demonstrable mirror movements in hand.     

Medical abortion in the first trimester: the use of serum hCG and endometrial thickness as markers of completeness.

OBJECTIVE: The combination of mifepristone and misoprostol is an established method for induction of early first trimester abortion, but there is no consensus about the best evaluation of treatment outcome. We assessed endometrial thickness, determined by ultrasound and serum-human chorionic gonadotropin (s-hCG) as markers of successful management. METHODS: Prospective trial involving 255 women, with a gestation of 62 days or less, who were to undergo medical abortion. In addition to our established routines of performing clinical and ultrasound examinations, we also determined the s-hCG level prior to treatment and at follow-up. RESULTS: Of the 255 subjects treated during the study, 20 (7.8%) were lost to follow-up. The overall complete abortion rate was 94.0%. Fourteen subjects required vacuum aspiration, nine of them prior to the scheduled follow-up and five thereafter. None of the pregnancies were ongoing. A decrease of 99% in s-hCG levels was noted in 99% of the women, when levels determined prior to mifepristone intake and those measured 15-71 days post-abortion were compared. CONCLUSION: This study confirms that s-hCG levels drop sharply after medical abortion. To assess the completeness of medical abortion, we recommend that clinical examination to be combined with determination of s-hCG. Ultrasonography should be carried out only when indicated.     

Conservation of receptor antagonist anti-tumor activity by epidermal growth factor receptor antibody expressed in transgenic corn seed

Recombinant protein production in plants such as corn is a promising means to generate high product yields at low comparable production cost. The anti-EGFR monoclonal antibody C225, cetuximab, is a well-characterized receptor antagonist antibody recently approved for the treatment of refractory colorectal cancer. We initiated a study to test and compare the functional activity of glycosylated and aglycosylated C225 produced in stable transgenic corn seed. Both corn antibodies were shown to be functionally indistinguishable from mammalian-derived C225 in demonstrating high-affinity binding to the EGF receptor, blocking of ligand-dependent signaling, and inhibiting cell proliferation. In addition, consistent with cetuximab, both corn antibodies possessed strong anti-tumor activity in vivo. Acute dose primate pharmacokinetic studies, however, revealed a marked increase in clearance for the glycosylated corn antibody, while the aglycosylated antibody possessed in vivo kinetics similar to cetuximab. This experimentation established that corn-derived receptor blocking monoclonal antibodies possess comparable efficacy to mammalian cell culture-derived antibody, and offer a cost effective alternative to large-scale mammalian cell culture production.     

☆Comparison of transcutaneous laryngeal ultrasound with video laryngoscope for assessing the vocal cord mobility in patients undergoing thyroid surgery

ObjectiveWe evaluated the accuracy and feasibility of transcutaneous laryngeal ultrasonography as an alternative to videolaryngoscopy for assessing vocal cord mobility to rule out recurrent laryngeal nerve injury following thyroidectomy.MethodsForty-five adult patients scheduled to undergo elective thyroidectomy under general anesthesia were included. Preoperatively, indirect laryngoscopy and transcutaneous laryngeal ultrasonography was done for assessing vocal cord mobility. Intraoperatively, following induction, patients were intubated using videolaryngoscope. On completion of the surgical procedure, one anesthetist performed videolaryngoscopy so as to record vocal cord mobility while the patients were being extubated in deep plane of anesthesia. Simultaneously another anesthesiologist performed transcutaneous laryngeal ultrasonography.Vocal cord mobility, changes in hemodynamics and total time duration for the two procedures was recorded. Indirect laryngoscopic assessment and flexible fiberoptic laryngoscopy was done on postoperative day 1 and 7 respectively.ResultsPostoperative videolaryngoscopy picked up bilaterally mobile vocal cords in 88.8% cases. Transcutaneous laryngeal ultrasonography could correctly identify 39(86.6%) of these patients, with 1(2.5%) patient being misdiagnosed as having bilaterally immobile vocal cords. Further, videolaryngoscopy identified 5 patients of vocal cord palsy, of which transcutaneous laryngeal ultrasonography correctly identified 3 (60%) patients. Hence, in comparison to videolaryngoscopy, the sensitivity, specificity, positive predictive value, and negative predictive value of transcutaneous laryngeal ultrasonography for assessment of vocal cords was 75%, 95.1%, 60%, and 97.5% respectively.ConclusionIn patients undergoing thyroidectomy, transcutaneous laryngeal ultrasonography can serve as a non-invasive, bedside screening tool for assessing vocal cord palsy postoperatively.     

Longer duration of homelessness is associated with a lower likelihood of non-detectable plasma HIV-1 RNA viral load among people who use illicit drugs in a Canadian setting

Homelessness is common among people who use drugs (PWUD) and, for those living with HIV/AIDS, an important contributor to sub-optimal HIV treatment outcomes. This study aims to investigate the relationship between the duration of homelessness and the likelihood of plasma HIV-1 RNA viral load (VL) non-detectability among a cohort of HIV-positive PWUD. We used data from the ACCESS study, a long-running prospective cohort study of HIV-positive PWUD linked to comprehensive HIV clinical records including systematic plasma HIV-1 RNA VL monitoring. We estimated the longitudinal relationship between the duration of homelessness and the likelihood of exhibiting a non-detectable VL (i.e., <500?copies/mL plasma) using generalized linear mixed-effects modelling. Between May 1996 and June 2014, 922 highly active antiretroviral therapy-exposed participants were recruited and contributed 8188 observations. Of these, 4800 (59%) were characterized by non-detectable VL. Participants reported they were homeless in 910 (11%) interviews (median: six months, interquartile range: 6–12 months). A longer duration of homelessness was associated with lower odds of VL non-detectability (adjusted odds ratio?=?0.71 per six-month period of homelessness, 95% confidence interval: 0.60–0.83) after adjustment for age, ancestry, drug use patterns, engagement in addiction treatment, and other potential confounders. Longer durations of episodes of homelessness in this cohort of HIV-positive illicit drug users were associated with a lower likelihood of plasma VL non-detectability. Our findings suggest that interventions that seek to promptly house homeless individuals, such as Housing First approaches, might assist in maximizing the clinical and public health benefits of antiretroviral therapy among people living with HIV/AIDS.     

Integrating Behavioral Health and Primary Care Services for People with Serious Mental Illness: A Qualitative Systems Analysis of Integration in New York

People with co-occurring behavioral and physical conditions receive poorer care through traditional health care services. One solution has been to integrate behavioral and physical care services. This study assesses efforts to integrate behavioral health and primary care services in New York. Semi-structured interviews were conducted with 52 professionals in either group or individual settings. We aimed to identify factors which facilitate or hinder integration for people with serious mental illness and how these factors inter-relate. Content analysis identified structural, process, organizational (“internal”) and contextual (“external”) themes that were relevant to integration of care. Network analysis delineated the interactions between these. We show that effective integration does not advance along a single continuum from minimally to fully integrated care but along several, parallel pathways reliant upon consequential factors that aid or hinder one another.     

Prevalence of malnutrition in a tertiary care hospital in India

Introduction:

Malnutrition adversely affects clinical outcome of hospitalized patients. This observational prospective study was done to assess the prevalence of malnutrition and its grade among patients admitted in a mixed intensive care unit (ICU) of a tertiary care hospital in order to help devise a comprehensive nutrition program for the malnourished.

Materials and Methods:

A total of 500 sequential patients admitted to the ICU were screened on admission over a year period for malnutrition using the Subjective Global Nutritional Assessment (SGNA) score. Distribution of the degree of malnutrition according to co-morbidities was also documented.

Results:

Of the total, 198 (39.6%) patients were malnourished, including one patient qualifying as severely malnourished; 68% patients were male, however, there was no statistically significant difference between nutrition status between sexes. Hypertension, diabetes, and cancer were the three most commonly encountered co-morbidities among the malnourished. A total of 86% of all cancer patients admitted were malnourished against only 12% of trauma patients.

Conclusion:

This study showed that almost two-fifth of the patients admitted were malnourished in this tertiary care hospital and that there is an urgent need to develop a comprehensive nutritional care program in many such Indian ICUs.
