Unilateral Presentation of Pulmonary Alveolar Proteinosis

Pulmonary alveolar proteinosis (PAP) is a rare disorder, in which lipoproteinaceous material accumulates within the alveoli. We report a case of a 27-year-old male patient with acute worsening of breathlessness over the last 7�months and cough with desaturation up to 79% on room air. Contrast-enhanced computerized tomography of the thorax revealed unilateral diffuse crazy-paving pattern likely PAP. Transbronchial lung biopsy confirmed the diagnosis of PAP. The present case highlights the unusual presentation of PAP with unilateral involvement. To the best of our knowledge, this is the first reported case of unilateral PAP from India with a biopsy diagnosis and resolution with whole lung lavage.

Effectiveness Of Cervical Stabilization Exercises With Feedback On Respiratory Status In Chronic Neck Pain Patients With Forward Head Posture

Background: Chronic neck pain is observed to be commonly kindred with forward head posture (FHP). Rib cage mechanics is found to be altered that decreases thoracic mobility. This reduced mobility of thorax reduces the effectiveness of diaphragm, intercostals, and abdominal muscles in terms of ventilation. Therefore this study was done to evaluate the effectiveness of exercises meant for enhancing the stability of the neck with feedback on neck stabilization exercises with feedback in improving the respiratory status. Methods: This was an experimental study. Based on inclusion & exclusion criteria, 100 subjects (54 males and 46 females) enrolled for the study, which was further allotted into Experimental and Control groups. The experimental group was given Cervical Stabilization Exercise with feedback in addition to routine Physiotherapy treatment. Control group was given only regular Physiotherapy treatment for six weeks. The digital camera assessed the FHP by measuring of Craniovertebral Angle (CVA). Spirometry assessed pulmonary function (FEV1) and Micro RPM assessed inspiratory muscle strength (PImax). All measurements were taken on the day of study, on 3rd and 6th week Results: Significant reduction in forward head posture measured by improvement in Craniovertebral angle, improvement in Inspiratory muscle strength (PIMax) and pulmonary functions (FEV1) were found in the group that received cervical stabilization exercises with feedback along with the conventional Physiotherapy (p< 0.05). Therefore it is suggested that cervical stabilization exercises correct the head posture and helps to improve the biomechanics of respiratory muscles. Conclusion: Cervical stabilization exercise is an effective approach to correct the forward head posture, and it should be included in the intervention measures of patients with forward head posture.

Designer insulins regimens in clinical practice--pilot multicenter Indian study.

BACKGROUND: Newer insulin analogues viz., premix insulin analogue (biphasic insulin aspart) and insulin glargine are now available in India. A multicenter all-India study was done to document the patient profile and responses to these analogues in routine clinical practice. METHODS: The study was conducted prospectively at 4 diabetes care clinics in different regions of India and collected data on the use of either of the two regimens A. Premix insulin analogue given twice-daily B. Basal-bolus analogue regimen (insulin aspart with every meal and insulin glargine once-a-day at bedtime). The centers collected all data at 3 time-points--baseline, 4 weeks later and end of 12 weeks. The study measures were FPG (fasting plasma glucose), PPPG (postprandial plasma glucose), HbA1c and insulin dose. FPG and PPPG were recorded at each of the three time points. HbA1c was recorded at baseline and end of study. Safety was assessed based on reported adverse drug reactions and occurrence of hypoglycaemias. RESULTS: Data of 145 patients was available for analysis (n=114 on premix insulin analogue and n=31 on basal-bolus analogue regimen). Baseline demography was comparable in the two groups. Both the regimens lowered all blood glucose parameters including HbA1c significantly as compared to baseline. However, the premix insulin analogue fared better than the basal-bolus regimen in lowering HbA1c (1.58 vs. 1.16% respectively; p<0.05). Also 41% more patients in the premix group could achieve target HbA1c of < 7% at the end of study. The mean insulin dose was lower with the premix analogue group at the end of 12 weeks. There was no significant difference between the two groups in terms of change in body weight. No major hypoglycaemias were reported and the percentage of patients experiencing a minor episode was lower with the premix analogue than the basal-bolus regimen both at 4 and 12 weeks (11.4 vs. 35.48%; 16.7 vs. 58.06% respectively). No adverse drug reactions were reported throughout the study. CONCLUSION: We conclude that both premix analogue administered twice a day and four times a day basal bolus regimen appear to be a convenient, safe and effective way of initiating insulin therapy in people with type-2 diabetes. The premix analogues achieves target better than the basal bolus regimen as has better compliance.

Bone mineral parameters in healthy young Indian adults with optimal vitamin D availability.

BACKGROUND: Several recent studies indicate a marked prevalence of vitamin D deficiency in asymptomatic, apparently healthy urban subjects from different socioeconomic groups in north India. METHODS: To further examine this trend, we studied 40 men and 50 women, 20-30 years of age, from the Indian paramilitary forces. These individuals consume a nutritious, high-protein diet, have optimal exposure to sunlight and undertake strenuous outdoor physical exercise. RESULTS: The mean serum calcium, phosphorus and alkaline phosphatase levels were normal in both men and women. The mean (SD) serum intact parathyroid hormone and 25-hydroxyvitamin D3 levels were 19.3 (8.2) pg/ml and 18.4 (5.3) ng/ml in men, and 11.9 (6.6) pg/ml and 25.3 (7.4) ng/ml in women. Bone mineral density estimated in 20 men and 22 women revealed that in comparison with white Caucasians, 35%-50% of men and 14%-32% of women were osteopenic at different sites, while an additional 10% of men had osteoporosis of the lumbar spine. CONCLUSION: We found that with optimal nutrition, good sunlight exposure and regular physical exercise, healthy young individuals have normal bone and mineral biochemical values. The reasons for the abnormalities detected in bone mineral density in them needs further study. The impact of childhood nutrition on accumulation of peak bone mass may contribute to our findings. There is a need for establishing normative bone mineral density data for Indians.

Pancytopenia--a six year study.

All cases of pancytopenia seen over a six year period in two hematology centres were analysed. Patients receiving myelotoxic chemotherapy or those with leukemic cells in peripheral smear were excluded. There were a total of 166 cases. The four major causes were: aplastic anaemia in 49, megaloblastic anaemia in 37, aleukemic leukemia or lymphoma in 30 and hypersplenism in 19 cases. Bone marrow aspiration was often unsuccessful in obtaining an adequate sample, while biopsy was usually diagnostic. Both bone marrow aspiration and biopsy should be performed simultaneously in pancytopenic patients when the diagnosis is elusive. Megaloblastic anaemia is a major cause of pancytopenia, and may present acutely in the critically ill. It is a rapidly correctable disorder and should not be missed.

Cryptococcal meningitis in acquired immunodeficiency syndrome.

OBJECTIVE: To study the clinical course and outcome of cryptococcal meningitis (CM) in patients with acquired immunodeficiency syndrome (AIDS). METHOD: Patients infected with human immunodeficiency virus (HIV) and symptoms suggestive of meningitis were evaluated with detailed history, clinical examination and investigations. Diagnosis of CM was based on positive India ink preparation or positive fungal culture of CSF. All patients were treated with amphotericin those showing response were put on oral fluconazole. RESULT: A total of 431 patients with HIV infection were admitted to this centre during the study period, of these 15 were diagnosed to have CM. Majority of the patients had a subacute presentation with signs of meningeal irritation seen in only seven patients. India ink preparation and positive fungal culture on cerebrospinal fluid (CSF) established diagnosis in all cases. All patients were treated with amphotericin B and fluconazole. Complete response was noticed in seven patients, two patients were lost to follow-up and six patients died during the course of therapy. Raised intracranial tension (ICT) and disseminated disease were associated with poor prognosis. CONCLUSION: CM is a common opportunistic fungal infection in patients with AIDS. A high index of clinical suspicion and routine mycological surveillance is required to diagnose this infection. Majority of patients respond to therapy except those who have disseminated infection, altered sensorium and features of raised ICT at presentation.

Ambulatory 24-hour electrocardiographic monitoring following total cavopulmonary connection.

A total of 72 patients (53 males, 19 females) in the age range 1-22 years (mean 6.4 years) who underwent univentricular repair between April 1990 and May 1997 at our institute were followed up from six months to seven years (mean 3.6 years). Twenty-four hours ambulatory electrocardiographic Holter monitoring was done in all the patients. Thirty-four out of 40 patients (85%) who underwent fenestrated total cavopulmonary connection and 25 out of 32 patients (78%) who underwent non-fenestrated total cavopulmonary connection had normal Holter recording; thus 59 out of 72 (82%) patients had normal findings. Among the fenestrated total cavopulmonary connections, three patients each had atrial tachycardia and sinus bradycardia. In the non-fenestrated group, two patients had atrial tachycardia, three had supraventricular tachycardia, one sinus bradycardia and one had intermittent ventricular tachycardia. No correlation was found between age at surgery, pre-operative morphology, cross clamp time or cardiopulmonary bypass time with post-operative arrhythmia. To conclude, post-operative arrhythmias following total cavopulmonary connection were not related to age at surgery, pre-operative morphology, cross clamp or cardiopulmonary bypass time. However, a larger patient pool and longer follow-up is required for evaluation of any definitive correlation.

Toxoplasmic encephalitis in acquired immunodeficiency syndrome.

OBJECTIVES: To study the clinical course and outcome of toxoplasmic encephalitis (TE) in patients with acquired immunodeficiency syndrome (AIDS). METHODS: Patients infected with human immunodeficiency virus (HIV) and neurological abnormality compatible with diagnosis of TE were enrolled in the study. These patients were treated with combination of trimethoprim/sulfamethoxazole and pyrimethamine. Response to therapy was assessed by clinical examination and repeat CT/MRI scan done after three weeks of starting treatment. Those showing response were put on prophylactic therapy. RESULTS: A total of 451 patients of HIV infections were admitted to this centre during the study period, of these 11 patients were diagnosed to have TE. The common presenting symptoms were fever (80%), seizures (45%), headache (45%) and altered sensorium (25%). Focal neurological deficit was present in 80% of cases. Nine cases had ring-enhancing lesions on CT scan while in the remaining two patient's ring lesions were seen on MRI. These were either multiple (55%) or solitary (45%). Antitoxoplasma antibody was detected in 10 patients. It was absent in one patient. Ten patients had clinical and radiological improvement with trimethoprim/sulfamethoxazole and pyrimethamine within 10 +/- 3 days of starting therapy. One patient died within 10 days of starting therapy. CONCLUSION: Toxoplasmosis is a common opportunistic infection of the central nervous system in patients with AIDS. Majority of patients with cerebral toxoplasmosis present with focal neurological abnormality in presence of characteristic neuroradiological abnormality and positive antitoxoplasma antibody titer. Response to empirical therapy helps to confirm the diagnosis, lifelong prophylaxis there after prevents relapse of potentially fatal and easily treatable condition.

An evaluation of oxidative stress in diabetes mellitus during uncontrolled and controlled state and after vitamin E supplementation.

OBJECTIVE: The study was conducted on 50 patients (10 insulin dependent diabetes mellitus (IDDM) and 40 non-insulin dependent diabetes mellitus (NIDDM) of recently diagnosed diabetes mellitus. The main objectives of the study were: 1. To evaluate oxidative stress at uncontrolled stage. 2. To evaluate the effect of optimal control on oxidative stress irrespective of type of drug therapy used. 3. To further evaluate the effect of vitamin E supplementation on oxidative stress after achieving optimal control. This was done in order to explore anti-oxidant effect of vitamin E. METHODS: Fifty patients of uncontrolled diabetes of less than 1 year duration and without any overt complications were studied. The parameters of oxidative stress included malonyl-di-aldehyde (MDA), reduced glutathione and vitamin E levels in the blood. They were done at three stages i.e. (a) In uncontrolled stage, (b) At controlled stage and (c) After 4 weeks of vitamin E supplementation in dosage of 400 mg daily. The parameters of control included fasting blood sugar < or = 140 mg%, post prandial < or = 200 mg and HbA1c < or = 7% (analysed by prepared kit). RESULTS: The significantly raised levels of MDA and decreased levels of reduced glutathione and vitamin E during uncontrolled stage of diabetes indicated free radical stress inducing lipid peroxidation. The significant fall of MDA and rise in reduced glutathione and vitamin E levels in blood after optimal control revealed its beneficial effect on oxidative stress. The levels were not normalised but still stayed higher than controls. After 4 weeks of vitamin E supplementation, further fall in MDA and rise in reduced glutathione suggested beneficial effect of vitamin E over and above the optimal control. Vitamin E estimation in blood at this stage did not constitute parameter of oxidative stress as it was provided from outside but was done to know the compliance of patients. Normalisation or near normalisation was not achieved with vitamin E therapy indicating persistence of oxidative stress. CONCLUSION: There was an evidence of oxidative stress in diabetes which decreased with optimal control and further declined after vitamin E supplementation indicating anti-oxidant effect of vitamin E alone. Normalisation of oxidative stress was not achieved. A further study is desired to study the effect of vitamin E for longer period at least 3-6 months before a definite conclusion is drawn.

Subcapsular tubercular liver abscess.

A young female married for the last 2 years but without any issue presented with lump in the right upper abdomen. This was proved to be a subcapsular liver abscess on USG and CT scan and proved to be tubercular on needle aspiration cytology. She was given four drugs antitubercular treatment (ATT). After four months of ATT she conceived and it was decided by both parents to continue the pregnancy. The three drug ATT was continued throughout the pregnancy and she delivered a perfectly healthy baby. Upto three months follow up the mother and baby were perfectly healthy. The subcapsular tubercular liver abscess is extremely rare and conception during treatment may be the first case in literature.

Bronchial responsiveness of non-smoking women exposed to environmental tobacco smoke or biomass fuel combustion.

We studied bronchial responsiveness (BR) in three groups of housewives with or without history of exposure to tobacco smoke or combustion of biomass fuels. Methacholine bronchoprovocation test was used to study BR. The group I subjects (60), who served as controls, were nonsmokers and had no chronic exposure to passive smoking or environmental tobacco smoke (ETS) or biomass fuels. Three of these women showed a 20 per cent FEV1 fall with a cumulative methacholine dose of 72.5 mg or less. Of 60 women in group II (ETS-exposure) and 52 in group III (biomass exposure), 26 (43.3%) and 10 (19.2%) respectively showed bronchial hyper-responsiveness (BHR). The odds ratios for BHR in groups II and III were 14.53 and 4.52 respectively. The number of hyper-responders was significantly more and the mean PD20 less in the exposed than the non-exposed groups. The occurrence of BHR in the ETS exposed group was more (P < 0.05) than the biomass combustion group. There were more hyper-responders (both groups II and III) amongst those who had an exposure index (EI) of 50 or more compared to those with EI of less than 50. We conclude that chronic cumulative exposure to both ETS and biomass combustion produces significant BHR. Further, BHR developed more often on ETS exposure, and when the exposure was present for a longer period.

Transbronchial lung biopsy in diffuse lung disease--a study of 28 cases.

Twenty-eight patients with diffuse lung disease underwent transbronchial lung biopsy during fibreoptic bronchoscopy. In 26 patients (93%) adequate tissue was obtained. Of these 26 biopsies specific diagnosis was possible in 20 (76%); a further 2 had non-specific inflammatory changes and a third, who was clinically normal, had normal lung. The inclusion of these cases raises the yield to 88%. The conditions most frequently seen were interstitial fibrosis (35%) and granulomatous diseases (31%). Three patients (11%) had procedure related pneumothorax; only one required a chest tube. This is a high yield, safe procedure and should be used more widely in India.
