Evaluation of Suspected Monoclonal Gammopathies: Experience in a Tertiary Care Hospital

Background

Monoclonal gammopathies occurs in patients with malignant diseases of plasma cells and lymphocytes and in few benign conditions. The objective of this study was to assess the precision, accuracy and confirmation of monoclonal gammopathies on serum protein electrophoresis (SPE) and the clinical relevance of detection and characterization of M component.

Methods

All samples received for serum electrophoresis in the last 3 years were analysed for data on M band positivity and correlating it with clinical profile of the patients. Immunofixation (IFE), Immunoelectrophoresis (IEP) and IgG, IgM estimation were carried out in few cases. The follow up of cases was done by serial monitoring of SPE and β₂ microglobulin levels.

Results

1155 samples were received during the 3 years period. 282 (24.4%) samples were positive for M component on SPE. Of these, 239 (84.8%) patients had M spike in λ region and 43 patients had M spike in β region. The mean load of the M protein band in the λ region was 37.8% and in β region was 35.8%. IgG with κ chain was seen in 40%, IgG with λ chain was seen in 50%, 5% patients each had IgM with κ and IgA with λ light chain. 246 samples (96.5%) had high levels of β₂ microglobulin. Of the 116 cases of multiple myeloma, IgG levels was more commonly raised (5%) as compared to IgA (6.9%) and IgM (5.2%).

Conclusion

It is recommended that SPE should be performed in patients having unexplained weakness, anaemia, back pain, osteoporosis, osteolytic lesions, fractures, renal insufficiency or recurrent infections.Key Words: Serum protein, Electrophoresis, M band, Multiple myeloma     

Cervical Disc Replacement for Spondylotic Myeloradiculopathy

Background

Cervical disc replacement is a newer concept and rapidly developing surgical treatment. A prospective study was conducted to determine, if accurately implanted Bryan''s cervical disc prostheses can provide relief from objective neurological symptoms and signs, stability and normal range of motion in cases of cervical disc prolapse with myeloradiculopathy.

Material and Method

Twenty patients underwent Bryan cervical disc replacement from Jan 2002 to Dec 2003. Young patients between age groups 21 to 50 years with degenerative cervical disc prolapse at C3-C7 with myeloradiculopathy were included in this study. Patients with significant facet joint arthropathy, unstable spine, trauma, tumour, osteoporosis and active infection were excluded from this study. Nurick''s grading was used for quantifying the neurological deficit. Patients were operated by anterior cervical approach using a specially designed Bryan''s cervical discectomy system. Neurological and radiological outcome was assessed post operatively and at 2,6,12 and 24 months follow up. Outcome analysis was carried out using modified Odom''s criteria. The radiographic results were assessed by taking antero posterior (AP) and lateral radiographs of cervical spine to find range of motion and device position.

Results

The patients were in the age group of 31 to 50 years. There were 14 (70%) male and 6 (30%) female in this study. Neck pain and brachialgia were the presenting symptoms in all cases, 12 (60%) had radiculopathy and 8 (40%) had myelopathy. Single level disc prolapse was present as per Magnetic Resonance Imaging (MRI) in four (20%) at C4-C5, 12 (60%) at C5-C6 and 4 (20%) at C6-C7. Bryan''s disc size 15 was used in 8 (40%) and size 17 was used in 12(60%) patients. During post-operative, 02, 06, 12, and 24 months follow up, the clinical outcome was excellent in 16 (80%) and good in 4 (20%) as per modified Odom''s criteria. There was demonstrated improvement in flexion, extension and rotation clinically and radiologically during follow up. There was no migration or displacement of device.

Conclusion

Cervical disc replacement for cervical disc prolapse with myeloradiculopathy represents an exciting new technology. Patients treated with the Bryan cervical disc prosthesis for single level cervical disc prolapse showed good to excellent improvement in neurological deficit. Clinically and radiologically maintenance of motion was found during follow up. More patients with longer follow up and post operative MRI to find out the protection to adjacent discs from abnormal stress will be required before this prosthesis is accepted as a treatment option.Key Words: Spondylotic myeloradiculopathy, Cervical disc replacement     

Body mass index, provider advice, and target gestational weight gain

OBJECTIVE: To study the relationships among prepregnancy body mass index (BMI), women's target gestational weight gain, and provider weight gain advice. METHODS: Project WISH, the acronym for Women and Infants Starting Healthy, is a longitudinal cohort study of pregnant women in the San Francisco Bay area. We excluded subjects with preterm birth, multiple gestation, or maternal diabetes. RESULTS: Among overweight women (prepregnancy BMI 26.1-29.0), 24.1% reported a target weight gain above the Institute of Medicine (IOM) guidelines, compared with 4.3% of normal weight women (P < .001). Among women with a low prepregnancy BMI (< 19.8), 51.2% reported a target weight gain below the guidelines, compared with 10.4% of normal weight women (P < .001). These patterns persisted in a multivariate analysis. Latina ethnicity, lower maternal education, low prepregnancy BMI (< 19.8), lack of provider advice about weight gain, and provider advice to gain below guidelines were all independently associated with a target weight gain below IOM guidelines. Prepregnancy BMI more than 26, multiparity, lower age, and provider advice to gain above guidelines were all associated with a target gain above IOM guidelines. CONCLUSION: Women's beliefs about the proper amount of weight gain and provider recommendations for weight gain vary significantly by maternal prepregnancy BMI. Many women report incorrect advice about gestational weight gain, and women with high or low prepregnancy BMI are more likely to have an incorrect target weight gain. New approaches to provider education are needed to implement the IOM guidelines for gestational weight gain.     

Contemporary issues in obstetrics and gynecology for the consultation-liaison psychiatrist

Medical advances in obstetrics and gynecology, combined with the depersonalization of health care and changes in sexual and reproductive behaviors in the general population, lead to challenging new problems for the psychiatric consultant who deals with reproductive issues. The author describes contemporary issues encountered in consultation-liaison work with the obstetrics and gynecology service in a general hospital. They include the reproductive implications of medical illnesses, the stress of deciding whether to continue a pregnancy known to carry genetic risk, the intrusiveness of certain options for dealing with infertility, parental expectations for a perfect baby, and the difficulties some traditional practitioners have in adapting their practice styles to the changing needs of the patient population.     

Psychiatric aspects of induced abortion

Approximately one third of the women in the United States have an abortion during their lives. In the year 2008, 1.21 million abortions were performed in the United States (Jones and Koolstra, Perspect Sex Reprod Health 43:41-50, 2011). The psychiatric outcomes of abortion are scientifically well established (Adler et al., Science 248:41-43, 1990). Despite assertions to the contrary, there is no evidence that abortion causes psychiatric problems (Dagg, Am J Psychiatry 148:578-585, 1991). Those studies that report psychiatric sequelae suffer from severe methodological defects (Lagakos, N Engl J Med 354:1667-1669, 2006). Methodologically sound studies have demonstrated that there is a very low incidence of frank psychiatric illness after an abortion; women experience a wide variety of feelings over time, including, for some, transient sadness and grieving. However, the circumstances that lead a woman to terminate a pregnancy, including previous and/or ongoing psychiatric illness, are independently stressful and increase the likelihood of psychiatric illness over the already high baseline incidence and prevalence of mood and anxiety disorders among women of childbearing age. For optimal psychological outcomes, women, including adolescents, need to make autonomous and supported decisions about problem pregnancies. Clinicians can help patients facing these decisions and those who are working through feelings about having had abortions in the past.     

The long-term effectiveness of generic adult fixed-dose combination antiretroviral therapy for HIV-infected Ugandan children

Background

Access to pediatric antiretroviral formulations is increasing in resource-limited countries, however adult FDCs are still commonly used by antiretroviral therapy (ART) programs.

Objective

To describe long-term effectiveness of using adult FDC of d4T+3TC+NVP (Triomune) in children for HIV treatment.

Methods

Clinical, immunologic, and virologic outcomes of HIV-infected ART-naïve children aged six months to 12 years, were evaluated up to 96 weeks post-ART initiation.

Results

From March 2004 to June 2006, 104 children were followed with a median age of 5.4 years, median CD4 cell percent and HIV-1 RNA were 11.0% (IQR 6.7–13.9) and 348,846copies/mL (IQR 160,941–681,313) respectively at baseline. Using Kaplan-Meir estimates, 75% of children had undetectable viral loads (<400copies/mL) at 96weeks of ART. Children with a baseline CD4 cell percent >15% were 3 times more likely to achieve viral load <400copies/mL than those with baseline CD4 cell percent <5% after adjusting for baseline age {aHR = 3.03 (1.10–8.32), p=0.03}; no difference was found among those with CD4 cell percent >5–14.9% and <5%.

Conclusion

Treatment with generic adult FDC for HIV-infected Ugandan children led to sustained clinical, immunologic and virologic response during 96 weeks of ART. Early initiation of ART is key to achieving virological success.
