1.  Postpartum Psychosis: Risk Factors Identification 
A better understanding of risk factors associated with postpartum psychosis may contribute to the better management.
This study was to identify the risk factors contributing to postpartum psychosis.
Materials and Methods:
In this cross-sectional, case control study 100 patients of postpartum psychosis (PP) were compared with the healthy controls. Risk factors explored were sociodemographic factors (age, education, occupation, income, and family type); positive family history; pregnancy and perinatal factors (number of antenatal check-up, parity, and complications during pregnancy, perinatal phase or in newborn); and presence of husband during peripartum period. Data were analyzed by graph pad instat software using chi square test and Fisher's exact test.
Total of 64% patients and 42% controls were less than 25 years of age (P = 0.001). Among the patients, 62% were primiparae compared with 46% in the controls (P = 0.02). Per capita family income was less than 5000 INR in 72% patients and 56% controls (P = 0.01). Maternal complications during perinatal period were observed in 38% patients and 22% controls (P = 0.01), while the complications in newborns were seen in 21% patients and 8% controls (P = 0.009). Husband was present in 58% patients and 76% controls. (P = 0.006).
The risk factors related to PP were younger age, lower per capita income, perinatal and neonatal complications, and absence of husband in peripartum phase.

2.  Three-Dimensional Supermacroporous Carrageenan-Gelatin Cryogel Matrix for Tissue Engineering Applications 
BioMed Research International  2013;2013:478279.
A tissue-engineered polymeric scaffold should provide suitable macroporous structure similar to that of extracellular matrix which can induce cellular activities and guide tissue regeneration. Cryogelation is a technique in which appropriate monomers or polymeric precursors frozen at sub-zero temperature leads to the formation of supermacroporous cryogel matrices. In this study carrageenan-gelatin (natural polymers) cryogels were synthesized by using glutaraldehyde and 1-ethyl-3-[3-dimethylaminopropyl] carbodiimide hydrochloride and N-hydroxysuccinimide (EDC-NHS) as crosslinking agent at optimum concentrations. Matrices showed large and interconnected pores which were in the range of 60–100 μm diameter. Unconfined compression analysis showed elasticity and physical integrity of all cryogels, as these matrices regained their original length after 90% compressing from the original size. Moreover Young's modulus was found to be in the range of 4–11 kPa for the dry cryogel sections. These cryogels also exhibited good in vitro degradation capacity at 37 °C within 4 weeks of incubation. Supermacroporous carrageenan-gelatin cryogels showed efficient cell adherence and proliferation of Cos-7 cells which was examined by SEM. PI nuclear stain was used to observe cell-matrix interaction. Cytotoxicity of the scaffolds was checked by MTT assay which showed that cryogels are biocompatible and act as a potential material for tissue engineering and regenerative medicine.

3.  Anabolic androgenic steroids in delayed diagnosis of tuberculosis 
This is the first case report depicting masking of symptoms of intestinal tuberculosis by anabolic androgenic steroids (AAS) causing delay in diagnosis which lead to a major surgery. Negative tuberculosis skin test (TST) probably due to immunomodulating effects of AAS also contributed to the delay. Patient also had early dependence on AAS and rapid growth of scrotal sebaceous cysts, findings of which have not yet been reported.

4.  Onset of Obsessive Compulsive Disorder in Pregnancy with Pica as the Sole Manifestation 
Pica refers to eating of non-nutritious substances, which is usually seen in childhood or pregnancy. Here we report a case of an illiterate tribal woman who developed pica as the sole manifestation of obsessive compulsive disorder, with onset during pregnancy. The patient had compulsions of eating uncooked rice or wheat, which resulted in toothache and abdominal discomfort. She had this habit in three pregnancies, consecutively. In the first two pregnancies it resolved spontaneously after puerperium, but persisted in the last one. Probably physical stress of limb edema during the third pregnancy was reason for the persistence. She responded to fluoxetine 40 mg / day after three months of treatment, without behavioral therapy. We conclude that pica may either be only a manifestation of obsessive compulsive disorder during pregnancy or it is an obsessive compulsive spectrum disorder.

6.  Carbamazepine-induced erythema multiforme major in an epileptic patient with bipolar affective disorder 
Carbamazepine (CBZ) is frequently used for epilepsy and various psychiatric illnesses. It is known for its dermatological side effects which may range from mild rash to life-threatening reactions as Stevens Johnson syndrome or toxic epidermal necrolysis. We hereby report a rare case of 17-year-old woman suffering from generalized tonic clonic epilepsy with comorbid bipolar affective disorder, who was initially treated with sodium valproate with partial improvement. After 19 days of addition of CBZ to the therapy, the patient developed erythema multiforme major with >60% skin involvement and oral, conjunctival, intestinal, and vaginal mucosal involvement.

7.  Multiple-etiology delirium and catatonia in an alcoholic with tubercular meningoencephalitis 
Industrial Psychiatry Journal  2011;20(2):139-141.
Delirium is a clinical entity with a variety of possible etiological conditions. Clinicians must be vigilant for the possibility of additional etiological factors. Secondly, catatonic patients should be carefully looked for general medical conditions. This case report depicts a chronic alcoholic who presented with withdrawal delirium, later on developed catatonia and then was diagnosed to have tubercular meningoencephalitis, a rare clinical sequence.

9.  Metabolic environment in substantia nigra reticulata is critical for the expression and control of hypoglycemia-induced seizures 
Seizures represent a common and serious complication of hypoglycemia. Here we studied mechanisms of control of hypoglycemic seizures induced by insulin injection in fasted and non-fasted rats. We demonstrate that fasting predisposes rats to more rapid and consistent development of hypoglycemic seizures. However, the fasting-induced decrease in baseline blood glucose concentration cannot account for the earlier onset of seizures in fasted versus non-fasted rats. Data obtained with c-fos immunohistochemistry and [14C]2-deoxyglucose uptake implicate a prominent involvement of the substantia nigra reticulata (SNR) among other structures in the hypoglycemic seizure control. This is supported by data showing that fasting decreases the SNR expression of KATP channels, which link metabolism with activity, and further confirmed with microinfusions of KATP channel agonist and antagonist. Data obtained with whole cell and perforated patch recordings from SNR neurons in slices in vitro demonstrate that both pre- and postsynaptic KATP channels participate in the failure of the SNR to control hypoglycemic seizures. The results suggest that fasting and insulin-induced hypoglycemia can lead to impairment in the function of the SNR, leading thus to hypoglycemic seizures.

10.  Reproductive tract infections in HIV positive women: A case control study 
Human immunodeficiency virus (HIV) infection primarily affects women during their reproductive years, and the coexistence of reproductive tract infections (RTIs) is not surprising given the fact that HIV is mainly acquired via heterosexual contact.
The aim of the study was to compare the occurrence of RTIs among infected and noninfected women.
Materials and Methods:
A case control study of 83 HIV positive women, tested by two enzyme linked immunosorbent assay (ELISA) and a matched control of 87 HIV negative women were screened for RTIs. They were submitted to gynecological examination and cervical cytology.
The mean age for HIV positive women was 30 years and that for HIV negative women was 27 years. 18% HIV positive women had menstrual irregularities compared to 6% in seronegative group (P= 0.024). Vaginal infections including sexually transmitted infections (STIs) were found in 47 (57%) HIV positive women and 30 (34%) HIV negative women (P= 0.0037). Vaginal candidiasis was the most common infection (34%) in HIV positive women, followed by trichomoniasis (12%). Human papilloma virus (HPV) infection was seen in nine HIV positive women versus none in HIV negative women. Cervical cytology showed inflammation in 53 (64%) HIV positive women compared to 27 (31%) HIV negative women (P= 0.000023). Genital neoplasia, including carcinoma in situ was observed in 2 (2.5%) HIV positive women and in none of the HIV negative women.
It is seen that reproductive tract morbidities are common in HIV positive women. So it is imperative that HIV positive women have a complete gynecological evaluation including a Papanicolaou (PAP) smear with aggressive screening of STIs.

11.  Phylogeography of mtDNA haplogroup R7 in the Indian peninsula 
Human genetic diversity observed in Indian subcontinent is second only to that of Africa. This implies an early settlement and demographic growth soon after the first 'Out-of-Africa' dispersal of anatomically modern humans in Late Pleistocene. In contrast to this perspective, linguistic diversity in India has been thought to derive from more recent population movements and episodes of contact. With the exception of Dravidian, which origin and relatedness to other language phyla is obscure, all the language families in India can be linked to language families spoken in different regions of Eurasia. Mitochondrial DNA and Y chromosome evidence has supported largely local evolution of the genetic lineages of the majority of Dravidian and Indo-European speaking populations, but there is no consensus yet on the question of whether the Munda (Austro-Asiatic) speaking populations originated in India or derive from a relatively recent migration from further East.
Here, we report the analysis of 35 novel complete mtDNA sequences from India which refine the structure of Indian-specific varieties of haplogroup R. Detailed analysis of haplogroup R7, coupled with a survey of ~12,000 mtDNAs from caste and tribal groups over the entire Indian subcontinent, reveals that one of its more recently derived branches (R7a1), is particularly frequent among Munda-speaking tribal groups. This branch is nested within diverse R7 lineages found among Dravidian and Indo-European speakers of India. We have inferred from this that a subset of Munda-speaking groups have acquired R7 relatively recently. Furthermore, we find that the distribution of R7a1 within the Munda-speakers is largely restricted to one of the sub-branches (Kherwari) of northern Munda languages. This evidence does not support the hypothesis that the Austro-Asiatic speakers are the primary source of the R7 variation. Statistical analyses suggest a significant correlation between genetic variation and geography, rather than between genes and languages.
Our high-resolution phylogeographic study, involving diverse linguistic groups in India, suggests that the high frequency of mtDNA haplogroup R7 among Munda speaking populations of India can be explained best by gene flow from linguistically different populations of Indian subcontinent. The conclusion is based on the observation that among Indo-Europeans, and particularly in Dravidians, the haplogroup is, despite its lower frequency, phylogenetically more divergent, while among the Munda speakers only one sub-clade of R7, i.e. R7a1, can be observed. It is noteworthy that though R7 is autochthonous to India, and arises from the root of hg R, its distribution and phylogeography in India is not uniform. This suggests the more ancient establishment of an autochthonous matrilineal genetic structure, and that isolation in the Pleistocene, lineage loss through drift, and endogamy of prehistoric and historic groups have greatly inhibited genetic homogenization and geographical uniformity.

12.  3D-QSAR CoMFA study of some Heteroarylpyrroles as Possible Anticandida Agents 
A three dimensional quantitative structure-activity relationship study using the comparative molecular field analysis method was performed on a series of 3-aryl-4-[α-(1H-imidazol-1-yl) aryl methyl] pyrroles for their anticandida activity. This study was performed using 40 compounds, for which comparative molecular field analysis models were developed using a training set of 33 compounds. Database alignment of all 33 compounds was carried out by root-mean-square fit of atoms and field fit of the steric and electrostatic molecular fields. The resulting database was analyzed by partial least squares analysis with cross-validation; leave one out and no validation to extract optimum number of components. The analysis was then repeated with bootstrapping to generate the quantitative structure-activity relationship models. The predictive ability of comparative molecular field analysis model was evaluated by using a test set of 7 compounds. The 3D- quantitative structure-activity relationship model demonstrated a good fit, having r2 value of 0.964 and a cross validated coefficient r2 value as 0.598. Further comparison of the coefficient contour maps with the steric and electrostatic properties of the receptor has shown a high level of compatibility and good predictive capability.

13.  Inhibitory effect of metalloporphyrins in conjunction with cholesterol on hepatic phospholipase A2 activityin vivo in rats 
We investigated the effect of cholesterol and the metalloporphyrins cobalt mesoporphyrin (CoMP) and chromium protoporphyrin (CrPP) on phospholipase A2 (PLA2) activity and the consequent hepatic mitochondrial stability as well as on lipid concentrations. Our studies revealed that on administration of cholesterol, CrPP, CoMP as well as simultaneous adminstration of cholesterol and CrPP, there was an inhibition of PLA2 activity. These moieties may therefore, be agents for preventing destabilisation of the mitochondrial membrane and the consequent pathological conditions which may arise due to membrane lysis. Our results revealed that cholesterol administration increased phospholipid concentration, albeit by modest amounts. Although the independent administration of metalloporphyrins led only to minor elevations in phospholipid concentration, the simultaneous administration of cholesterol and CrPP generated a steep elevation in the concentration of total phospholipid. Since cholesterol inhibits PLA2 activity it has the potential of being therapeutic agent for preventing the pathological conditions which may arise due to membrane lysis.
