Iodine deficiency status amongst school children in Pauri,Uttarakhand

Objective

To assess the iodine deficiency status amongst school age children in district Pauri, Uttarakhand.

Methods

2067 children (age of 6–12 years) were included. Clinical examination of thyroid gland of each child was conducted. On-the-spot urine and salt samples were collected from children.

Results

Total Goitre Rate was found to be 16.8% and median Urinary Iodine Concentration level was 115 μg/L. Only 40.4% of salt samples had e 15 ppm of iodine.

Conclusion

There is a mild degree of iodine deficiency in school age children in district Pauri. There is a need of strengthening the National Iodine Deficiency Disorder Control Program.     

Oxidative stress and antioxidant capacity in patients with chronic pancreatitis with and without diabetes mellitus

Aim

To determine oxidant stress and antioxidant capacity in chronic pancreatitis (CP) patients with and without diabetes mellitus.

Methods

This study is a secondary data analysis of our earlier study on 127 (male?=?86) patients with CP, grouped as those with diabetes (case; n?=?23) and those without diabetes (control). Markers of antioxidant status included vitamins A and E, total antioxidant capacity (TAC; measured as ferric-reducing ability of plasma [FRAP]), and total glutathione (T-GSH). Markers for oxidative stress included lipid peroxidation, measured as thiobarbituric acid reactive substances (TBARS) and serum superoxide dismutase (s-SOD).

Results

Patients with diabetes were older (mean [SD] age 36.4 [9.7] vs. 29.3 [10.0] years; p?=?0.032), had longer duration of CP [4 (0.3?C21) vs. 3 (0.3?C24) years; p?=?0.07), and had a lower TAC (269.8 [92.4] vs. 355.5 [128.6] ??moles Fe⁺² liberated; p?=?0.003) compared to those without diabetes. In multiple logistic regression analysis taking all exploratory variables, FRAP (<270 ??moles Fe⁺² liberated) was associated with diabetes independent of duration of CP, age of patients, and TBARS levels. However, oxidative stress levels were not different between diabetic and nondiabetic patients.

Conclusions

Diabetes was found to be associated with longer duration of CP and with low antioxidant capacity. Further studies will be needed to evaluate a causal association.     

Living donor intestinal transplant using a standardized technique: first report from India

Aim

We describe the first living donor intestinal transplant (LDIT) in India and discuss the indications and problems of this complex procedure.

Methods

A 43-year-old male patient required massive bowel resection for gangrene due to thrombosis of the superior mesenteric artery. He was maintained on parenteral nutrition but developed cholestasis and well as repeated catheter related infections with progressive loss of venous access due to thrombosis of central veins. A LDIT was performed using 200?cm of small intestine from the patient's son. The graft was based on the continuation of the superior mesenteric vessels beyond the ileocolic branch. The artery was anastomosed directly to the aorta and the vein to the venacava.

Results

The graft functioned well and he was weaned off parenteral nutrition. However, he later developed complications (wound dehiscence and enterocutaneous fistula) and developed sepsis. He succumbed to sepsis with a functioning graft 6?weeks after the transplant. The donor recovered uneventfully and was discharged on the 4th postoperative day.

Conclusions

LDIT can be life saving in patients with intestinal failure and failure of parenteral nutrition. There is a need to introduce this modality in India. In a setting of scarcity of deceased donor organs the living donor option has advantages.     

Intractable ascites as a manifestation of Wolman’s disease: report of two sibs

Wolman disease (WD) is a rare, inherited, rapidly fatal condition presenting in early infancy. The disease manifests in the first month of life with failure to thrive, vomiting, diarrhea, abdominal distension, hepatosplenomegaly and bilateral adrenal calcification and is nearly always fatal before the age of 1?year. Barring a case report of isolated fetal ascites, there is no report of intractable ascites as the presentation of WD till date. We report two siblings with WD who both had intractable ascites and required therapeutic paracentesis, albumin infusion, and diuretics to control tense ascites. Although rare, WD should be considered in the differential diagnosis of infantile ascites.     

Incremental value of live/real time three-dimensional transesophageal echocardiography over the two-dimensional technique in the assessment of aortic aneurysm and dissection

We compared findings from intraoperative live/real time three-dimensional transesophageal echocardiography (3DTEE) and two-dimensional transesophageal echocardiography (2DTEE) with surgery in 67 patients having aortic aneurysm and/or aortic dissection. Of these, 20 patients had aortic aneurysm without dissection, 21 aortic aneurysm and dissection, and 26 aortic dissection without aneurysm. 3DTEE diagnosed the type and location of aneurysm correctly in all patients unlike 2DTEE, which missed an aneurysm in one case. There were four cases of aortic aneurysm rupture. Three of them were diagnosed by 3DTEE but only one by 2DTEE, and one missed by both techniques. The mouth of saccular aneurysm, site of aortic aneurysm rupture, and communication sites between perfusing and nonperfusing lumens of aortic dissection could be viewed en face only with 3DTEE, enabling comprehensive measurements of their area and dimensions as well as increasing the confidence level of their diagnosis. In all patients with aortic dissection, 3DTEE enabled a more confident diagnosis of dissection because the dissection flap when viewed en face presented as a sheet of tissue rather than a linear echo seen on 2DTEE which can be confused with an artifact. 2DTEE missed dissection in one patient. In six cases the dissection flap involved the right coronary artery orifice by 3DTEE and surgery. These were missed by 2DTEE. Aortic regurgitation severity was more comprehensively assessed by 3DTEE than 2DTEE. Aneurysm size by 3DTEE correlated well with 2DTEE and surgery/computed tomography scan. In conclusion, 3DTEE provides incremental information over 2DTEE in patients with aortic aneurysm and dissection.     

Noradrenergic Function in Suicide

Although abnormalities in serotonergic function have been the major focus of studies on suicidal behavior, several studies indicate that abnormalities of noradrenergic function may also be involved in the pathophysiology of suicide. In this paper, we have reviewed some of the noradrenergic studies in sucide, including studies of the biosynthetic enzyme for norepinephrine, tyrosine hydroxylase (TH), the receptors for norepinephrine, α- and β-adrenergic receptors, as well as the signaling cascades linked to β-adrenergic receptors. In general, these studies indicate that the protein expression of TH, as well as α₂- and β₂-adrenergic receptors, is increased in the postmortem brain of suicide victims. More studies are needed in order to examine extensively the role of noradrenergic function in suicidal behavior.     

Characterization of microsatellite loci for Cypripedium kentuckiense (Orchidaceae)

Cypripedium kentuckiense is one of the 15 Cypripedium species found in North America. Its populations are threatened by illegal collection and land conversion. Assessing the level of genetic variation within-and-among populations employing species-specific and variable co-dominant molecular markers such as microsatellite can assist in developing appropriate conservation strategies. For the first time, we report eight polymorphic nuclear microsatellite markers for C. kentuckiense. Number of alleles per locus ranged from two to eight and the mean number of alleles across eight loci was 4.13. Mean observed (H _o ) and expected heterozygosity (H _e ) values were 0.514 and 0.522, respectively. The eight markers reported in this study can be used to estimate genetic diversity, genetic structure, gene flow, and mating system of the species.     

Dilated ascending aorta is associated with the difficulty in correct placement of pulmonary artery catheter

The present case report highlights that a tense mega-sized aortic root and ascending aorta can mechanically resist the passage of fully inflated (1.5 ml air) balloon to wedge-trace position in the pulmonary artery. Any attempt to push the catheter rather predisposed its recoiling and rebutting into the right ventricle and the cardiac arrhythmia. Inflating continuous cardiac output catheter balloon with lesser volume of air (1 ml) is suggested to overcome this problem.
