Hemiazygous continuation of inferior vena cava draining into the coronary sinus via persistent left superior vena cava: a rare anomaly.

We present a case of left sided inferior vena cava with hemiazygous continuation draining into the coronary sinus via the left persistent superior vena cava. This was incidentally found in an individual referred to our centre for evaluation of palpitations. These caval anomalies are rare, and are often associated with no clinical manifestations. However, it is necessary to recognize them during routine workup to avoid diagnostic and procedural pitfalls.

Transient left ventricular dysfunction after therapeutic pericardiocentesis - Takotsubo cardiomyopathy or pericardial decompression syndrome.

We present a case of reversible left ventricular (LV) dysfunction with characteristic stress or "Takotsubo" cardiomyopathy (SCM) after therapeutic pericardiocentesis in a patient with tubercular pericardial effusion. SCM following pericardiocentesis is uncommon, as opposed to the well-defined entity, pericardial decompression syndrome (PDS). PDS is defined as a paradoxical deterioration of hemodynamics and development of severe biventricular dysfunction, cardiogenic shock, and pulmonary edema after uneventful, often large volume pericardiocentesis in patients of pericardial effusion.

Scrub typhus infection, not a benign disease: an experience from a tertiary care center in Northern India.

INTRODUCTION: Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. It is characterised by fever, rash, myalgia and diffuse lymphadenopathy. Most common complications are sepsis, shock, acute respiratory distress syndrome (ARDS), hepatitis, pre renal azotemia and multi organ dysfunction syndrome (MODS). Mortality rates range from 7-30% in untreated cases. Scrub typhus is endemic to a part of the world known as 'the tsutsugamushi triangle'. River banks, grassy areas generally harbour scrub typhus infection; however, recently there has been an increase in prevalence of infection from dry regions like Haryana. OBJECTIVE: To assess the clinical spectrum and complications of scrub typhus infection at a tertiary care centre in North India. MATERIAL AND METHODS: An observational study was conducted on patients >14 years old with acute febrile illness >7 days duration, admitted indoor from emergency department, from July to November 2017. Suspected cases were tested for specific IgM antibodies against Orientia tsutsugamushi by ELISA. RESULTS: Among the 230 patients, screened for scrub typhus infection, 39 (16.95%) came out to be positive. Most common patient complaints were fever followed by cough and breathlessness, myalgia, nausea, vomiting and behavioral abnormality. 15% of patients required inotropic support initially and 48% had oxygen saturation of less than 90% at the time of presentation. Pleural effusion and crepitations were present in 41% of patients. Most common biochemical alterations were: abnormal liver function tests (95%), followed by thrombocytopenia, anemia, abnormal renal function tests, and hyponatremia. 12 patients (30.7%) were shifted to intensive care unit, 8 of which (20.5%) needed invasive mechanical ventilation and 4 patients (10.3%) underwent hemodialysis. Various complications were noted in 89.7% of cases, the most common being ARDS followed by sepsis, acute kidney injury (AKI) and meningitis. The mortality rate in this study was 18%. CONCLUSIONS: This study emphasizes that scrub typhus infection is on a rampant resurgence and it is associated with significant complications. High degree of suspicion as well as development of effective measures to treat, control and prevent is critical to lower the disease burden.

Rare Occurrence of Drug Induced Subacute Cutaneous Lupus Erythematosus with Leflunomide Therapy.

Leflunomide is an immunomodulatory drug exhibiting anti-inflammatory, anti-proliferative and immunosuppressive effects. It has been widely used for treatment of active rheumatoid arthritis. Despite its good safety profile cutaneous side effects like alopecia, eczema, pruritis and dry skin have been reported with Leflunomide use. Skin ucleration, vasculitis, lichenoid drug rash and Subacute Cutaneous Lupus Erythematosus (SCLE) have been rarely reported with its use. A rare case of Leflunomide induced SCLE is being reported in a female patient with rheumatoid arthritis. The clinical features, histopathological and immunological characteristics were consistent with drug induced SCLE. Withdrawal of Leflunomide along with short course of topical steroids resulted in resolution of symptoms suggesting the drug to be the culprit. As this drug comes into widespread use, it remains to be seen whether more cases of DI-SCLE will occur/be reported. Fortunately, such a condition till times appears rare and is reversible once the drug is discontinued thus avoiding over evaluation and over treatment if the triggering drug is recognized.

Living with Amputation: Anxiety and Depression Correlates.

INTRODUCTION: Trauma accounts for 16% of the total burden of disease in the world, making it a leading cause of morbidity and mortality especially in the developing nations. India represents about 10% (225million) of the total world workforce in agriculture. With the evolution of new machinery and better techniques of agriculture, there has been a substantial increase in the associated injuries. Depression, anxiety and post-traumatic stress are among the predictors of poor quality of life (QOL). AIM: This study was aimed to assess and correlate of traumatic amputation on the patient's mental health in the Northern Indian rural setting. MATERIALS AND METHODS: This cross-sectional study included subjects who had undergone traumatic amputations. A pre-tested, semi-structured questionnaire was administered to each study participant after an informed verbal consent. The questionnaire had two parts. The first part gathered socio-personal and the disability related information from the patient and the second part included a Hospital Anxiety and Depression Scale (HADS). RESULTS: The mean anxiety and depression scores were 9.10±5.7 and 3.44±3.42, respectively. The length of original inpatient stay, people at hand for help, number of hospitalizations, number of follow ups per year, type of family (nuclear versus joint), pain perception, optimism, rehabilitation satisfaction and lower limb amputations correlated significantly with anxiety levels in the patients. The depression levels correlated significantly only with perception of pain. CONCLUSION: The amputees have a large number of psychosocial concerns which need to be addressed to provide a holistic care and a better QOL. It is essential to sensitize the community, the health care providers and the patient's family to the additional psychosocial needs of the amputee.

An Increase Incidence in Uric Acid Nephrolithiasis: Changing Patterns.

INTRODUCTION: Nephrolithiasis is a complex disease affecting all age groups globally. As the causative factors for nephrolithiasis rises significantly, its incidence, prevalence and recurrence continues to baffle clinicians and patients. AIM: To study the prevalence of different types of renal stones extracted by Percutaneous Nephrolithotomy (PCNL) and open surgical procedures. MATERIALS AND METHODS: Renal stones from 50 patients were retrieved by Percutaneous Nephrolithotomy (PCNL), Ureterorenoscopy (URS) and open surgical techniques for qualitative tests for detection of calcium, oxalate, uric acid, phosphate, ammonium ion, carbonate, cystine and xanthine. RESULTS: Three patients had stone removed by open surgery and rest had undergone PCNL. Nine of the stones were pure of calcium oxalate, 9 were of pure uric acid and 32 were mixed stones. Forty one stones had calcium. Among the mixed stones, oxalate was present in 25 samples (39 of total), uric acid was seen in 17 (25 of total stones), phosphate was present in 23 (23 of total) and carbonate was present in 4 stones (4 of total). Only 1 patient had triple phosphate stone. 12 were of staghorn appearance of which 6 were of struvite type, 6 were pure uric acid and remaining were mixed oxalate-phosphate stones. CONCLUSION: Our study, though in a small number of hospital based patients, found much higher prevalence of uric acid stones and mixed stones than reported by previous hospital based studies in north India (oxalate stones~90%, uric acid~1% and mixed stones~3%). Biochemical analysis of renal stones is warranted in all cases.

Immediate Postpartum Intrauterine Contraceptive Device Insertions in Caesarean and Vaginal Deliveries: A Comparative Study of Follow-Up Outcomes.

Background. Immediate postpartum intrauterine contraceptive device (IPPIUCD) is a lucrative postpartum family planning method which provides effective reversible contraception to women in the delivery setting. Our aim was to study the clinical outcomes of IPPIUCD insertions and compare them as a factor of route of insertion (vaginal versus caesarean). Methods. This is a retrospective analytical study done in a tertiary care teaching institute. A Cohort of 593 vaginal and caesarean deliveries with IPPIUCD insertions, over a two-year period, was studied and compared for follow-up results. Outcome measures were safety (perforation, irregular bleeding, unusual vaginal discharge, and infection), efficacy (pregnancy, expulsions, and discontinuations), and incidence of undescended IUCD strings. Descriptives were calculated for various outcomes and chi square tests were used for comparison in between categorical variables. Results. Overall complication rates were low. No case of perforation or pregnancy was reported. Spontaneous expulsions were present in 5.3% cases and were significantly higher in vaginal insertions (p = 0.042). The incidence of undescended strings was high (38%), with highly significant difference between both groups (p = 0.000). Conclusion. IPPIUCD is a strong weapon in the family planning armoury and should be encouraged in both vaginal and caesarean deliveries. Early follow-up should be encouraged to detect expulsions and tackle common problems.

The health benefits of vitamin K.

Vitamin K has important functions within the body, some of which are still being discovered. Research has shown that vitamin K is an anticalcification, anticancer, bone-forming and insulin-sensitising molecule. Recent data indicate that subclinical vitamin K deficiency is not uncommon. Additionally, vitamin K antagonists such as warfarin may cause detrimental side effects, which may partly be blunted through vitamin K supplementation.

Acarbose: safe and effective for lowering postprandial hyperglycaemia and improving cardiovascular outcomes.

α-Glucosidase inhibitors (AGIs) are a class of oral glucose-lowering drugs used exclusively for treatment or prevention of type 2 diabetes mellitus. AGIs act by altering the intestinal absorption of carbohydrates through inhibition of their conversion into simple sugars (monosaccharides) and thus decrease the bioavailability of carbohydrates in the body, significantly lowering blood glucose levels. The three AGIs used in clinical practice are acarbose, voglibose and miglitol. This review will focus on the cardiovascular properties of acarbose. The current available data suggest that AGIs (particularly acarbose) may be safe and effective for the treatment of prediabetes and diabetes.

Coenzyme Q10 for the treatment of heart failure: a review of the literature.

Coenzyme Q10 (CoQ10) is an endogenously synthesised and diet-supplied lipid-soluble cofactor that functions in the mitochondrial inner membrane to transfer electrons from complexes I and II to complex III. In addition, its redox activity enables CoQ10 to act as a membrane antioxidant. In patients with congestive heart failure, myocardial CoQ10 content tends to decline as the degree of heart failure worsens. A number of controlled pilot trials with supplemental CoQ10 in heart failure found improvements in functional parameters such as ejection fraction, stroke volume and cardiac output, without side effects. Subsequent meta-analyses have confirmed these findings, although the magnitude of benefit tends to be less notable in patients with severe heart failure, or within the context of ACE inhibitor therapy. The multicentre randomised placebo-controlled Q-SYMBIO trial has assessed the impact of supplemental CoQ10 on hard endpoints in heart failure. A total of 420 patients received either CoQ10 (100 mg three times daily) or placebo and were followed for 2 years. Although short-term functional endpoints were not statistically different in the two groups, CoQ10 significantly reduced the primary long-term endpoint-a major adverse cardiovascular event-which was observed in 15% of the treated participants compared to 26% of those receiving placebo (HR=0.50, CI 0.32 to 0.80, p=0.003). Particularly in light of the excellent tolerance and affordability of this natural physiological compound, supplemental CoQ10 has emerged as an attractive option in the management of heart failure, and merits evaluation in additional large studies.

Evidence-based diuretics: focus on chlorthalidone and indapamide.

Thiazide and thiazide-like diuretics are cornerstone treatments for hypertension. However, unlike chlorthalidone (CTD) and indapamide (IDP), hydrochlorothiazide (HCTZ) lacks evidence for reducing morbidity and mortality as monotherapy compared with placebo or control. Despite this fact, HCTZ is prescribed much more frequently than CTD or IDP. We believe that all hypertension guidelines should follow the National Institute for Health and Excellence (NICE) and make IDP and CTD first choice 'thiazide-like diuretics.' This article will focus on the available evidence pertaining to HCTZ versus CTD and IDP. We will review the pharmacological differences between these three diuretics, as well as the clinical trial data and important side effects.

Endocrine and metabolic disease: Confocal microscopy as a diagnostic aid.

Diabetes is a systemic disease associated with many complications. These can be prevented and managed effectively if detected promptly. Confocal microscopy (CFM) is a diagnostic tool which has the potential to help in early detection of disease and timely management. CFM has the potential to serve as an excellent noninvasive modality for in vivo imaging and morphological analysis, which can aid us in assessing and monitoring various infectious and pathological diseases at the cellular level. Besides ophthalmological indications, CFM has shown good sensitivity and specificity for identifying those at risk of neuropathy and foot ulceration, monitoring evolution and therapeutic response in a wide range of neuropathies apart from diabetic neuropathy. Through this communication, we aim to sensitize the endocrinologists towards cerebral cavernous malformation as a biomarker to evaluate potential outcomes and therapies in human diabetic neuropathy.

Worldwide burden of diabetes.

Diabetes is a pandemic of major public health importance cannot be disputed. While the IDF data does emphasis the importance of diabetes as a global public health problem, it does not place in perspective the ranking of diabetes as compared to other diseases and illnesses. The GBD data highlight this fact in multiple ways. The disease and its complications or comorbid conditions rank high in the list of risk factors, and causes of death. This communication describes the global burden of diabetes especially south-east Asia and the statistical sequelae of the disease.

Akt inhibitors: mechanism of action and implications for anticancer therapeutics.

Akt, better known as protein kinase B (PKB), is a serine/threonine-specific protein kinase which acts as mediator via PI3K/Akt pathway in many biological processes like glucose metabolism, apoptosis, cell differentiation and transcription. Akt1 gene amplification has been implicated in gastric carcinoma while Akt2 amplification has been linked with ovarian, pancreas, breast and stomach tumors. The use of Akt inhibitors as monotherapy or in combination with other anticancer drugs could be useful for combating drug resistance and improving response. Thus, comprehensive understanding of Akt and its linked signaling pathways (PI3K, PKB, mTOR etc.) is necessary to lead to newer drug development and use.

Hypoglycemia perception: Cross-cultural differences in Punjabi and Hindi speaking postmenopausal women.

INTRODUCTION: The cross cultural differences in perception of menopausal symptoms are well known and these differences in perception of hypoglycemic symptoms in Russian-speaking and Caucasian postmenopausal women have been reported. AIMS AND OBJECTIVES: This study assessed cross - linguistic and cross - cultural differences in symptomatology of self reported hypoglycemia, between Punjabi and Hindi speaking diabetic post menopausal women. MATERIAL AND METHODS: Thirty Punjabi speaking and 20 Hindi speaking diabetic postmenopausal women aged over 50 years, were recruited for this study. Each subject was asked, what happens to you when you have low sugar? in the language of her choice, and spontaneous answers were recorded verbatim. STATISTICAL ANALYSIS: The data so obtained was analyzed by paper and pen method to obtain an understanding of the frequency of self reporting of various symptoms and then analyzed using Statistical Package for Social Science ver.19.0. RESULTS: Symptoms of hollowness, cold sweats and headache correlated significantly (P < 0.0001, P = 0.0001 and P = 0.03 respectively). One difference was noted in women from rural vs. urban background: Inability to concentrate was more frequent in urban women (4/23) vs rural women (0/27) (P < 0.0001). DISCUSSION: To our knowledge, this is the first exploratory work highlighting the differences in self reported hypoglycemia symptomatology, based on linguistic background. In India and other countries with multi ethnic, multi linguistic societies, linguistic competence in hypoglycemia history taking is important. LIMITATIONS: Incidence of hypoglycemia in the subjects enrolled was not assessed. Many of the subjects in the Punjabi speaking cohort were bilingual. Some symptoms of hypoglycemia may have been missed or over-reported by participants. CONCLUSION: Diabetes care professionals should be aware that persons with diabetes from varying linguistic backgrounds may report symptoms of hypoglycemia differently.
