A comparison of immunomodulation therapies in mechanically ventilated patients with Guillain Barré syndrome

A comparison of the effectiveness of immunomodulatory therapies in patients with Guillain Barré syndrome (GBS) who require mechanical ventilation (MV) is important for patient treatment and cost. We aimed to compare the effectiveness of three modes of intervention on the outcome of patients with GBS receiving MV: intravenous immunoglobulin (IVIgG); small volume plasmapheresis (SVP) and large volume plasmapheresis (LVP). Patients with GBS satisfying National Institute of Neurological and Communicative Disorders and Stroke 1990 criteria and requiring MV between 1997 between 2007 were analyzed. The primary outcome parameters evaluated were mortality, duration of MV, hospital stay and Hughes scale at discharge from hospital. Of the 173 (Male: Female, 118:55) patients who required MV during the study, 106 patients received single modality treatment (IVIgG 31, LVP 45, SVP 30) based on availability, affordability and feasibility. Patients receiving IVIgG had a higher incidence of severe weakness and bulbar involvement. The mean duration of MV (p = 0.61), total hospital stay (p = 0.44) and Hughes scale at discharge (p = 0.31) did not differ among the three groups. Complications were similar in the three treatment groups except for hypoalbuminemia and anemia, which were more common in patients in the LVP group. In conclusion, the outcome of patients treated with these three immunomodulatory treatment modalities did not vary. The beneficial effects of SVP in our study warrant further randomized control trials especially in resource-constrained settings.     

Anxiety symptoms in patients with frontal lobe epilepsy versus generalized epilepsy

PurposeThe aim of this study was to compare the frequency of anxiety symptoms between patients with frontal lobe epilepsy (FLE) and generalized epilepsy (GE).MethodsForty and 78 patients with FLE and GE respectively were enrolled in the study. Anxiety symptoms were measured with the Hamilton anxiety rating scale (HARS) and the anxiety subscale of the hospital anxiety and depression scale (HADSA).ResultsCompared to the GE group, the FLE group had significantly higher HARS (10.9 ± 8.7 vs. 7.9 ± 6.8, p = 0.039) scores. Significant correlations were also found between anxiety symptoms and epilepsy-related variables, particularly with the seizure frequency and the number of currently taken anti-epileptic drugs.ConclusionAnxiety symptoms are more common in patients with FLE in comparison to those with GE. Further studies are warranted to clarify the relationship between anxiety symptoms and FLE.

Meta-analysis of adherence to highly active antiretroviral therapy in patients with HIV infection in China

With the widespread implementation of antiretroviral therapy in many countries, the HIV/AIDS epidemic has declined. However, little is known about the prevalence of adherence rate to Highly Active Antiretroviral Therapy (HAART) in patients with HIV infection in China. This is the first meta-analysis of cross-sectional studies of treatment adherence (≥ 95%) to HAART in Chinese patients. Both English (PubMed, PsycINFO, EMBASE, and Web of Science) and Chinese (WanFang, CNKI, and SinoMed) databases were systematically and independently searched by three investigators. Studies with adherence rate estimates of HAART were included. Adherence rate estimates of each eligible study were extracted and pooled using the random-effects model. A total of 40 studies conducted in China were eligible and analyzed. The mean rate of?≥?95% adherence to HAART was 81.1% (95%CI: 75.1%–88.0%, I²?=?97.3%) at one week, 80.9% (95%CI: 74.7%–85.9%, I²?=?96.6%) at one month, and 68.3% (95%CI: 46.1%–84.4%, I²?=?97.1%) at 3 months or longer. Subgroup analyses revealed that samples with no gender predominance, low education level, middle economic region, rural area, older age (42.3 years), and recent publication (2013 or later) were correlated to higher HAART adherence. The average rate of HAART adherence was relatively high in China, which indicates effective HIV/AIDS policy, prevention and control measures. However, the HAART adherence rate decreased over the study time period.     

A SEARCH FOR UNHAPPY ABDOMEN: PREVALENCE OF IRRITABLE BOWEL SYNDROME IN GENERAL POPULATION

The irritable bowel syndrome is the commonest gastrointestinal disorder seen in practice but its exact prevalence in India is not known. This study was carried out to determine the prevalence of symptoms compatible with this diagnosis in general population. A cross sectional random sample survey was conducted in various strata of urban population in Wanoworie area of Pune. Survey utilized personal interviews based on a questionnaire. Symptoms were evaluated as per Manning criteria and the diagnosis of irritable bowel syndrome was defined by Kruis diagnostic index. Of the 1010 subjects interviewed, 370 (37%) reported more than 6 episodes of abdominal pain in previous 6 months, with 333 reporting symptoms consistent with the the diagnosis of irritable bowel syndrome. At least one of the Manning''s symptoms was present in 307 out of 370 subjects (83%). The male female ratio was 5.3:1. Among males, 288 (35%) and among females 82 (53.2%) persons had at least some degree of abdominal discomfort. Other common symptoms were: excessive passage of wind (42.2%), irregular bowel habits (33%), excessive belching (30.8%), constipation (27.5) and feeling of incomplete evacuation(28.1%). About one third of the symptomatic subjects (134 or 36.2%) had seen a doctor or wanted to be seen by a specialist. Overall prevalence of the symptoms consistent with irritable bowel syndrome thus, is 33 per cent though only about a third of these may possibly consult a doctor. Follow up of all these patients for a mean duration of 8.3 months showed that no case of organic disease was picked up either by the scoring system or by the gastroenterologist. Symptoms consistent with the diagnosis of irritable bowel syndrome are see in almost one third of the study population residing in Wanoworie area of Pune.KEYWORDS: Irritable bowel syndrome, Kruis diagnostic index, Manning''s symptoms     

Hormone Receptors,Her-2/Neu and Chromosomal Aberrations in Breast Cancer

Background

There is a great deal of disparity in the incidence of breast cancer in rural and urban India on one hand and between India and Western population on the other.

Methods

We analysed steroid receptor status in cases of breast cancer in a small sample of patients in armed forces. Infiltrating duct carcinomas of breast recorded histologically in mastectomy specimens in last two years were accessioned in the present study with reference to patient and tumour characteristics.

Result

In contrast to the higher rates reported in western literature, only 33 % of the tumours expressed estrogen receptors (ER) and progesterone receptors (PR), of which 24% were ER positive and 30% PR positive. Negative steroid receptor status did not correlate with presence or absence of metastatic nodes, however it was predominant amongst the high grade infiltrating duct carcinomas in this study. Necrosis and lymphovascular invasion demonstrated an inverse relationship with the ER/ PR reactivity. 70% of the node positive cases expressed Her –2/ Neu, reflecting a higher immunoreactivity in this subset of patients. Aneusomy for chromosomes 1, 11 and 17 was common in node positive cases.

Conclusion

Evaluation of chromosomal aberrations by Fluorescent In Situ Hybridization (FISH) technique correlates well with traditional histological parameters.Key Words: Breast carcinoma, Hormone receptors, Her –2/ Neu
