Are patients comfortable with medical students examining them?

A key feature of medical curricula across the world is the interaction of medical students with patients at teaching hospitals. However, patients may not be comfortable engaging with medical students in certain situations, and there are a number of possible reasons for this. Teaching hospitals often overlook the need to take consent for such interactions. Certain measures can be taken to increase the confidence of patients in the medical students treating them. Studies on the subject make it clear that this ethical question is common throughout the world.

A study of prevalence of asymptomatic bacteriuria in pregnant women from rural areas attending to Obstetric Department in Akash Hospital, Karnataka, India

Background: Asymptomatic bacteriuria (ASB) in pregnancy is a significant risk factor for developing upper urinary tract infection and pyelonephritis which is associated with significant maternal and fetal risks. The aim of this study was to know the prevalence of asymptomatic bacteriuria in pregnancy, to identify the organisms and their antibiotic susceptibility patterns and to formulate a single or combined rapid screening method as an acceptable alternative to urine culture.Methods: A total of 375 pregnant women aged between 18 to 45 years were included in this study. Clean catch mid-stream urine samples were collected. Screening tests done were gram staining of uncentrifuged urine, pus cell count, nitrite test and leukocyte esterase test. Identification of pathogens and antibiotic sensitivity tests were performed as per standard urine culture and sensitivity methods.Results: Out of the 375 pregnant women, 31 (8.4%) had significant bacteriuria. High percentage of women with ASB were primigravidas (51.38%) and in 2nd trimester (43.86%). The most common organism isolated was E.coli (56.14%). In screening tests, gram staining of uncentrifuged urine had a sensitivity of 85.71%. Sensitivity of 71.42% was found in Nitrite and leucocyte esterase tests. However, the combination of these two tests, with either test positive, showed sensitivity and negative predictive value of 90.47% and 99.09% respectively.Conclusions: Early detection and treatment of ASB in pregnancy can prevent complications. ASB can be identified by simple and combined rapid screening methods and urine culture along with antibiogram. Therefore, screening and treatment of ASB may be incorporated as routine antenatal care for safe motherhood and healthy newborn.

Multichannel somato sensory evoked potential study demonstrated abnormalities in cervical cord function in brachial monomelic amyotrophy.

Background: Brachial monomelic amyotrophy (BMMA) is known to affect the central cervical cord gray matter resulting in single upper limb atrophy and weakness. Settings and Design: Case series of BMMA patients who underwent somatosensory evoked potentials (SEP) studies at a tertiary referral center. Aims: We proposed to record Multichannel Somatosensory Evoked Potentials (MCSSEP) from median and ulnar nerves with neck in neutral and neck fully flexed position in 17 patients with classical BMMA seen over three years. Materials and Methods: Recordings were done from both median (MN) and ulnar nerves (UN). N9, P9, N13, N20 potentials were recorded and amplitudes measured. SSEPs were performed in 22 age-matched healthy men. Amplitudes of cervical response were calculated by N13/P9 ratio and compared in both positions. Results: Among the controls N13 amplitude was always normal {MN: mean N13/P9 - 0.96 in neutral; 0.95 in flexed}{UN: mean N13/P9 - 0.82 in neutral; 0.83 in flexed}, and mean amplitudes did not reveal any difference in both conditions ( P> 0.05). Among 17 patients N9, P9 and N20 responses were normal in neutral position. Flexion showed no change in latency or amplitude of N9 and N20 responses ( P -0.63) whereas the N13 response was abnormal in at least one tested nerve in the affected limb (MN: P < 0.01; UN: P < 0.01). During flexion, N13 response was abnormal in 14 (82%) patients after MN stimulation and in all 17(100%) after UN stimulation {MN: mean N13/P9 - 0.62 in neutral; 0.38 in flexed}{UN: mean N13/P9 - 0.55 in neutral; 0.31 in flexed}. Conclusion: MCSSEP in BMMA with neck flexion caused a significant reduction of the cervical N13 response indicating segmental cervical cord dysfunction.

Hepatic myelopathy: a rare complication following extrahepatic portal vein occlusion and lienorenal shunt.

A 19-year-old gentleman presented with slowly progressive spastic paraparesis, 2 years after the therapeutic lienorenal shunt for portal hypertension secondary to cirrhosis and portal vein occlusion. After 2 years of initial evaluation, the motor functions had not worsened further. He did not have any obvious clinical or EEG features of hepatic encephalopathy. Other causes for myelopathy were ruled out. Contribution of portal vein occlusion to portosystemic shunting has not been reported previously in patients with 'hepatic myelopathy.' This uncommon complication needs to be considered in patients with shunt surgery for relieving portal hypertension.

Localized hypertrophy of hand in syringomyelia.

Segmental amyotrophy is a common feature resulting from extension of the syrinx into the anterior horns. Segmental hypertrophy in the form of chiromegaly/podomegaly or limb and hemi-hypertrophy are rare but well recognized clinical feature of syringomyelia. We report a case of hand hypertrophy secondary to syringomyelia. Hypertrophy of the hands is a rare but interesting feature of syringomyelia and in all cases of enlargements of hands syringomyelia should be considered in the differential diagnosis.
