Prevalence of Hand Disorders in Type 2 Diabetes Mellitus and its Correlation with Microvascular Complications

Background: Physicians have long recognized the association between diabetes mellitus and several pathologic conditions of the hand. The most commonly recognized maladies are limited joint mobility (LJM), Dupuytrens disease (DD), trigger finger (TF), and carpal tunnel syndrome (CTS). Incidence of these hand disorders has increased in the setting of diabetes. Collectively, these are described as diabetic hand syndrome. Aim: The aims were to find out the prevalence of hand disorders in diabetic patients, and to study the relation of these hand disorders with microvascular complications. Subjects and Methods: This is an observational cross-sectional case-control study done over a period of 1 year Patients of type 2 DM, of age < 65 years, who visited Gandhi Memorial Hospital, Lucknow were enrolled and were described as cases. Age- and sex-matched nondiabetic individuals were taken in the control group. The data were analyzed using software SPSS. SPSS Inc. Released 2008. SPSS Statistics for Windows, Version 17.0. Chicago: SPSS Inc. Means and standard deviations were computed; the Student t-test and Chi-square (χ2) test were used as appropriate. Results: A total of 400 subjects were studied, 200 each in the case and control groups. Of total 200 diabetic patients, 30% (60/200) patients had neuropathy, 37.5% (75/200) had nephropathy, and 44.5% (89/200) patients had retinopathy. In the study population, 67% patients were having one or more hand disorders, in which LJM was found in 40.5% (81/200) patients, DD was found in 19% (38/200) patients, TF in 16.5% (33/200), and CTS in 14% (28/200) patients. Conclusions: This study shows a high prevalence of hand disorders in diabetic patients and also correlates with the duration of type 2 DM, LJM being the most common hand disorder and more common in patients who have microvascular complications.

Comparative study of effectiveness of Pap smear versus visual inspection with acetic acid and visual inspection with Lugol's iodine for mass screening of premalignant and malignant lesion of cervix

Background and Objective: Cancer of the cervix is a leading cause of morbidity and mortality among women worldwide. Therefore, to curb the disease, there is a need to develop a screening test that has good sensitivity and specificity. The present study is aimed to compare the effectiveness of the Pap smear, visual inspection with acetic acid (VIA) and visual inspection with Lugols iodine (VILI) for mass screening of premalignant and malignant lesions of the cervix; to evaluate the usefulness of VIA and VILI as an adjunct to improve sensitivity of cervical cytology; and to evaluate the role of VILI as a parallel screening method with VIA to enhance its test performance. Design and Setting: This was a prospective, analytical study in which 210 patients of the reproductive age group attending the gynecology OPD were enrolled. Patients and Methods: Patients were first subjected to Pap smear followed by VIA, VILI, colposcopy and biopsy for confirmation of lesion, if needed. Data was obtained and statistically analyzed. Results: Of the 210 patients, 34 (16.27%) had positive Pap test, 29 (13.87%) had positive VIA and 24 (11.43%) had positive VILI and 31 (14.75%) showed features of cervical intraepithelial neoplasia (CIN) on colposcopy. Of the total of 48 patients in whom either of the screening tests was positive and had undergone cervical biopsy, one had CIN-3, three had CIN-2, 12 had CIN-1, three had carcinoma in situ CIS and 29 reported normal. In our study, 40 patients were picked up as positive by combination of these tests, of which 19 (47.50%) had CIN on biopsy. Conclusion: Our study showed that VIA and VILI had sensitivity comparable to Pap smear and can thus be a suitable potential alternative/adjunctive screening test not only in a resource-poor setting but in well-equipped centers also. And, use of a combination of tests (Pap+VIA+VILI) had 100% sensitivity but at cost of low specificity and more false-positive results.

Association of carotid plaque echogenicity with recurrence of ischemic stroke.

Background: Atherosclerosis is related to various cardiovascular and cerebrovascular events like cerebral infarction. Recurrence of ischemic stroke is specifically related to atherosclerotic load as determined by the presence of carotid atheromatous plaques and its echogenicity. Aim: This study was to evaluate the association of recurrence of stroke with echogenic characteristics of carotid plaque in ischemic stroke patients. Materials and Methods: Carotid sonography using high-resolution 7.5 MHz along with gray-scale technique was done in each ischemic stroke patient to find the occurrence of plaque and its echogenicity according to Mannheim Carotid Intima-Media Thickness Consensus (2004-2006). Followup of patient done to know the recurrence of stroke during 6-month duration and its association with plaque echogenicity. Results: A significant association found between the presence of plaque and known cerebrovascular risk factors. Also significant association found between recurrence of stroke and echolucent character of carotid plaque in bivariate analysis (P = 0.0028). Conclusions: Recurrence of stroke is related to advanced stage of atherosclerosis that is specified by carotid plaque and its characteristics. It will help us to identify groups of patients at different risk for stroke and planning better strategies to prevent such events.

Acute hypokalaemic quadriparesis in dengue fever.

The authors report acute hypokalaemic quadriparesis in two young patients that occurred during dengue epidemic in 2010 in India. Both patients developed flexic type of pure motor weakness in all four limbs without bladder bowel involvement, following 2 to 3 days of fever and malaise. Higher mental functions were normal. Serum potassium level was very low; 2–2.5 m mol/l. Non-structural protein (NS1)-antigen and immunoglobulin M-antibody for dengue were positive in both patients. Both patients improved with potassium supplementation. In follow-up, they are doing well.

The etiological diagnosis and outcome in patients of acute febrile encephalopathy: A prospective observational study at tertiary care center

BACKGROUND Acute febrile encephalopathy (AFE) is a clinical term used to an altered mental state that either accompanies or follows a short febrile illness and is characterized by a diffuse and nonspecific brain insult manifested by a combination of coma, seizures, and decerebration. OBJECTIVE To identify the etiological diagnosis and outcome in adult patients with AFE. SETTINGS AND DESIGN A prospective observational study was done in patients aged 14 years or above who were admitted with AFE at a tertiary care center in northwest India. MATERIALS AND METHODS The non-infectious causes of unconsciousness were excluded and then only a diagnosis of AFE was considered. Cerebrospinal fluid (CSF) analysis and imaging of brain was done to determine the possible etiology. Outcome was assessed at 1 month of follow-up after discharge by using modified Rankin Scale (mRS). Data were analyzed and presented as mean, median, and percentages. A P value of <0.05 was considered significant. RESULTS Of the total 120 patients studied, pyogenic meningitis was the most common cause accounting for 36.7%, followed by acute viral encephalitis (AVE) in 28.33% of the patients (Japanese B encephalitis in 12.5%, herpes simplex virus encephalitis in 3.33%, and other undetermined viral etiology in 12.5%). Cerebral malaria, sepsis associated encephalopathy (SAE), and tuberculous meningitis were diagnosed in 21.7%, 9.17%, and 4.2% of cases, respectively. Of the total, 16 patients died, 6 with AVE, 3 with pyogenic meningitis, 3 with cerebral malaria, and 4 with SAE. mRS at discharge was >3 in 14 patients with AVE (P < 0.001), and in the remaining it was <3. After 1 month, mRS was >3 in six patients with AVE and in the rest it was ≤1 (P < 0.001). CONCLUSIONS In this study, pyogenic meningitis was the leading cause of AFE, followed by AVE and cerebral malaria. The outcome in cases with AVE can be fatal or more disabling than other etiologies.

Cardiac abnormalities in HIV-positive patients: results from an observational study in India.

Background: The clinical presentation of cardiac abnormalities in HIV-infected patients may be atypical or masked by concurrent illnesses that lead to misdiagnosis or they remain undiagnosed; therefore, this study was aimed to determine the frequency of cardiac abnormalities in HIV-infected patients. Material and Methods: Consecutive HIV-infected patients of age >13 years were studied for 3 months, after obtaining their consent. After clinical assessment, chest x-ray, electrocardiogram, 2-dimensional echocardiography and serum Troponin T levels were done. Results: A total of 100 patients were studied, cardiomegaly was observed in the x-ray of 15% of them, abnormal electrocardiogram was seen in 18%, 2-dimensional echocardiography was abnormal in 67%; and diastolic dysfunction (42.8%) was the commonest abnormality followed by dilated cardiomyopathy (17.6%). Serum troponin T was elevated in 8%. The variables, opportunistic infections (OIs), antiretroviral therapy (ART), stage of HIV disease, and CD4 counts, did not affect the frequency of diastolic dysfunction. Conclusion: The diastolic dysfunction is the most common cardiac abnormality observed in HIV-infected patients.

Accidental phosgene gas exposure: A review with background study of 10 cases

Here, authors present a review on clinical presentation and management of exposure of phosgene gas after reviewing the literature by searching with keywords phosgene exposure on Google, Cochrane, Embase and PubMed with a background of experience gained from 10 patients who were admitted to our institute after an accidental phosgene exposure in February 2011 nearby a city in India. Phosgene is a highly toxic gas, occupational workers may have accidental exposure. The gas can also be generated inadvertently during fire involving plastics and other chemicals and solvents containing chlorine, which is of concern to emergency responders. Phosgene inhalation may cause initially symptoms of respiratory tract irritation, patients feel fine thereafter, and then die of choking a day later because of build up of fluid in the lungs (delayed onset non-cardiogenic pulmonary edema). Phosgene exposure is associated with significant morbidity and mortality. Patients with a history of exposure should be admitted to the hospital for a minimum of 24 h for observation because of the potential for delayed onset respiratory failure and acute respiratory distress syndrome.

Subdural haematoma and axonal polyneuropathy complicating dengue fever

The authors report a case of dengue fever presenting with aseptic meningoencephalitis and developing subdural haematoma and pure motor quadriparesis due to axonal polyneuropathy. This 27-year-old female patient presented to us during the latter part of the dengue epidemic in India in 2010. She had mild thrombocytopaenia and subtle signs of capillary leak. Dengue-specific IgM antibody was positive. She presented initially with recurrent seizures. Initial CT scan of brain was normal with cerebrospinal fluid showing albuminocytologic dissociation. After 6 days, the patient developed quadriparesis with areflexia. MRI showed bilateral subdural haematoma with no evidence of spinal nerve root compression. The nerve conduction study showed evidence of axonal neuropathy. The patient’s quadriparesis improved such that she was able to walk with support after 4 weeks with conservative management. This case report highlights a possible association between dengue and motor axonal neuropathy subtype of Guillain–Barré syndrome.

Atypical rabies with MRI findings: clue to the diagnosis

Rabies is known for most as a fatal infectious disease, mainly transmitted to both humans and animals through bites by rabid animals. In its classical form, rabies is well recognised, but when it presents atypically in paralytic form, it may become difficult to distinguish from Guillain–Barré syndrome (GBS) or myelitis, particularly where history is not forthcoming or concealed. The authors report here an atypical case of paralytic rabies presenting with descending paralysis followed by furious form where clue to suspicion was MRI findings. Imaging in rabies is seldom done. MRI findings of rabies encephalitis are well known, but in myelitis these need to be further characterised. The authors present MRI findings in a confirmed case of rabies myelitis. The differential diagnosis of the imaging findings as well as the role and the relevance of imaging in the diagnosis of this disease are discussed.

An atypical case of dengue haemorrhagic fever presenting as quadriparesis due to compressive myelopathy

Dengue haemorrhagic fever is a serious presentation of dengue viral infection. Case reports of cerebral haemorrhage due to dengue are rare. The authors report a rare case of dengue haemorrhagic fever presenting with fever and acute onset progressive quadriparesis of the upper motor neuron type. Rare cases of quadriparesis in dengue fever have been reported in the literature due to myositis, Guillain–Barre syndrome, myelitis and hypokalaemia. This case on investigations was found to have extramedullary compression due to haematoma in the cervical region as the cause of quadriparesis.
