Lipid and lipoprotein profiles among middle aged male smokers: a study from southern India

<p>Abstract</p> <p>Objectives</p> <p>The objectives were to investigate into the relationship between lipid profile including Apolipoprotein-A1 (Apo-A1) and Apolipoprotein-B (Apo-B) and smokers and to relate them with smoking pack years.</p> <p>Materials and Methods</p> <p>A total of 274 active male smokers without any other illnesses and age matched male healthy control subjects (78) with similar socio-cultural background were assessed for clinical details, dietary habits, physical activities, smoking and alcohol consumption. Standard methods were adopted to check the lipid levels. The data were analyzed statistically.</p> <p>Results</p> <p>Their ages ranged from 40 to 59 years, systolic BP from 110 to 130 mmHg, and diastolic BP from 76 to 88 mmHg. All of them had similar pattern of diet (vegetarianism with occasional meat). None was on any medication influences lipid level. Their physical activity was moderate. Number of pack years varied from 10 to 14 (mild), 15 to 19 (moderate) and 20 and above (heavy) among 69, 90 and 115 cases, whose mean ages were 43, 44 and 49 respectively. The mean (+SD) values in mg/dl of total cholesterol (TC), Triglyceride (TGL), Apo-B, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol and Apo-A1 in mg/dl among mild/ moderate/ heavy smokers and control subjects were 198 (30.6)/ 224 (27.2)/ 240 (24.3) and 160 (20.4); 164(42.6)/ 199 (39.5)/ 223(41.7) and 124 (31.6); 119 (24.9)/ 121 (27)/ 127 (28.3) and 116 (21.4); 94 (19.7)/ 104 (21.8)/ 120 (20.5) and 82 (17.6); 42 (5.9)/ 39 (3.1)/ 35(4.4) and 48 (5.3); and 120 (17)/ 119 (21)/ 115 (25) and 126 (19), respectively. In smokers, there was a rise in TC, TGL, LDL, Apo-B and fall in HDL and Apo-A; these changes were significant (P < 0.05).</p> <p>Conclusion</p> <p>Number of pack years was directly proportional to abnormal lipid profile. It is also concluded that changes in Apo-A1 and Apo-B were more significant when compared to HDL and LDL cholesterol among smokers. In the view of double risk for smokers (smoking and altered lipid profile) efforts may be made to introduce smoking cessation program.</p

Live Fish Impaction in Hypopharynx in an Elderly Patient

SummarySuccessful removal of a live fish impacted in the hypopharynx of a 65-year-old male is reported to emphasize the importance of the speed with which it has to be recognized and intervened. The present report also highlights the altered sensory perception in the oral cavity of elderly people as a potential risk factor for airway obstruction due to a foreign body. Moreover, the possibility of a foreign body has to be suspected, if an elderly patient without any cardiorespiratory illness presents with an acute onset of progressive respiratory distress

Priapism following a juvenile Russell’s viper bite: an unusual case report

Following a bite from a juvenile Russell’s Viper (Daboia russelii), a priapism (painful erection) developed rapidly in a 16-year old male and only subsided after administration of antivenom three hours later. Potential mechanisms for this snakebite-induced priapism are unclear but likely due to venom toxins causing nitric oxide release and subsequent vasodilation of endothelium in the corpus cavernosum although the possible involvement of other mechanisms cannot be ruled out. We strongly believe that this unusual case report may lead to further scientific research in order to improve the clinical understanding of the pathophysiology of envenomation due to Russell’s viper bites. Although it is too early to speculate, further research may also discover the possibilities of developing venom-based candidate molecules to treat sexual dysfunction in males and females

Bilateral simultaneous optic neuritis following envenomations by Indian cobra and common krait

In India, most snakebite envenomation (SBE) incidents are caused by the “Big Four” snakes which include Russell’s viper, common krait, Indian cobra, and saw-scaled viper. Their common en-venomation effects include neurotoxicity, myotoxicity, and coagulopathy. However, they also in-duce rare complications such as priapism, pseudoaneurysm and sialolithiasis. Ocular manifesta-tions such as optic neuritis develop rarely following envenomations by non-spitting snakes and they may cause temporary vision changes and blindness if untreated. While optic neuritis fol-lowing Indian cobra envenomation has been reported previously, this was not encountered in vic-tims of common kraits. Hence, for the first time, we report optic neuritis developed in a victim following envenomation by a common krait and compare its clinical features, and diagnostic and therapeutic methods used with another case of optic neuritis in a victim of an Indian cobra. Both patients received antivenom treatment and made an initial recovery, however, optic neuritis de-veloped several days later. The condition was diagnosed using ophthalmic examination together with computed tomography and/or magnetic resonance imaging methods. Due to very similar clinical features, both patients received intravenous corticosteroids which restored their vision and successfully treated optic neuritis. This case report suggests that the optic neuritis developed in a common krait envenomation is comparable to the one developed following a cobra bite, and therefore, the same diagnostic and therapeutic approaches can be used. This study also raises awareness of this rare complication and provides guidance for the diagnosis and treatment of SBE-induced optic neuritis

Ultrasound-guided compression method effectively counteracts Russell’s viper bite-induced pseudoaneurysm

Russell’s viper (Daboia russelii), one of the ‘Big Four’ venomous snakes in India is responsible for a majority of snakebite-induced deaths and permanent disabilities. Russell’s viper bites are known to induce bleeding/clotting abnormalities as well as myotoxic, nephrotoxic, cytotoxic and neurotoxic envenomation effects. In addition, they have been reported to induce rare envenomation effects such as priapism, sialolithiasis and splenic rupture. However, Russell’s viper bite-induced pseudoaneurysm (PA) has not been previously reported. PA or false aneurysm is a rare phenomenon that occurs in arteries following traumatic injuries includ-ing some animal bites, and it can become a life-threatening condition if not treated promptly. Here, we document two clinical cas-es of Russell’s viper bites where PA has developed despite antivenom treatment. Notably, a non-surgical procedure, ultra-sound-guided compression (USGC), either alone, or in combination with thrombin was effectively used in both the cases to treat the PA. Following this procedure and additional measures, the patients made complete recoveries without the recurrence of PA which were confirmed by subsequent examination and ultrasound scans. These data demonstrate the development of PA as a rare complication following Russell’s viper bites and the effective use of a simple, non-surgical procedure, USGC for the successful treatment of PA. These results will create awareness among healthcare professionals on the development of PA and the use of USGC in snakebite victims following Russell’s viper as well as other viper bites

Partial segmental thrombosis of the corpus cavernosum following Russell’s viper bite

Snakebite envenoming (SBE) is common in rural communities living in tropical regions that often have fragile and/or overwhelmed healthcare systems. The complex scenarios around SBE lead to a high number of deaths, disabilities, and long-term consequences in patients. Russell’s viper (Daboia russelii) is one of the most medically important snake species in India, which causes devastating pathological conditions characterised by a wide range of clinical manifestations. This broad spectrum of symptoms requires additional therapeutic interventions beyond the classical antivenom administration. Hence, positive outcomes for patients affected by SBE can be achieved with a better understanding of previous experiences describing clinical manifestations and various therapeutic interventions including for rare and underreported conditions. Here, we report an SBE victim who developed partial segmental thrombosis in the corpus cavernosum following Russell’s viper envenomation and its diagnostic and treatment approaches. The patients received 180 ml of antivenom to resolve the abnormalities in their haematological parameters. Despite antivenom treatment, they developed severe pain in their genital region, and subsequent ultrasound and magnetic resonance imaging confirmed segmental thrombosis in the corpus cavernosum, which required supportive measures. The treatment using low molecular weight heparin, rivaroxaban and non-steroidal anti-inflammatory drugs resolved segmental thrombosis. In conclusion, this case report exemplifies the development of a rare segmental thrombosis in corpus cavernosum and how the medical, scientific, and general community can benefit from documenting clinical manifestations, medically relevant insights into patient care and the management of underreported complications

Risk factors for myocardial infarction among low socioeconomic status South Indian population

<p>Abstract</p> <p>Background</p> <p>As longevity increases, cases of myocardial infarction (MI) are likely to be more. Cardiovascular disease (CVD) is a major global health problem reaching epidemic proportions in the Indian subcontinent, also among low socio-economic status (SES) and thin individuals.</p> <p>Objectives</p> <p>The present study was undertaken to elicit risk factors for MI among low SES Southern Indians and to find out its association with body mass index (BMI).</p> <p>Materials and methods</p> <p>A case-control study of patients with MI matched against healthy control subjects was carried out in a tertiary care teaching hospital. Standard methods were followed to elicit risk factors and BMI. Chi-square and Fishers exact test for categorical versus categorical, to show relationship with risk factors were analyzed.</p> <p>Results</p> <p>A total of 949 patients (male (M) = 692 and post menopausal female (F) = 257) and 611 age and sex matched healthy controls were included. In our study, BMI was below 23 in 48.2% of patients and below 21 in 22.5%. The risk of developing MI was significantly more in males (odds ratio (OR) = 3.3, 95% confidence interval (C.I.) = 2.69-4.13), among females with post-menopausal duration (PMD) of more than or equal to 3 years (OR = 9.27, 95% C.I. = 6.36-13.50) and in those with BMI less than 23 with one or other risk factors (P = 0.002, OR = 1.38, 95% C.I. = 1.13-1.70).</p> <p>Conclusion</p> <p>BMI cannot be considered as a lone independent risk factor, as the study population had low BMI but had one or more modifiable risk factors. It would be advisable to keep BMI at least 21 kg/m²for screening program. Health education on life style modification and programs to diagnose and control diabetes and hypertension have to be initiated at community level in order to reduce the occurrence.</p
