Association of Maternal Serum Ischemia Modified Albumin (IMA) with Placental Histopathological Changes and Fetomaternal Outcome: A Prospective Case Control Study in Normotensive and Pre-eclamptic Women.

Introduction: Ischemia and oxidative stress leads to generation of hydroxyl free radicals and modification of 'N-terminus' of human serum albumin. This modified albumin molecule, known as Ischemia Modified Albumin (IMA), is elevated in early stages of ischemia. It has recently been approved by US Food and Drug Administration (US FDA) for its clinical use, as early marker of myocardial ischemia in cardiology. IMA is a novel marker of ischemia and is elevated in other clinical conditions associated with ischemia like pulmonary embolism, uncontrolled type II diabetes mellitus, acute decompensated heart failure, preeclampsia, recurrent pregnancy losses and IUGR. Role of IMA in birth asphyxia in perinatology is of current interest and needs further research. Methodology: A prospective case control study was conducted in a tertiary center in North India for one year. Total 80 pregnant women between 34 and 40 weeks were recruited and allocated in two groups. Case group comprised of 40 pre-eclamptic pregnant women and control group comprised of 40 normotensive pregnant women. Comparison and association of maternal serum IMA levels with fetomaternal outcome and number and types of placental histopathological changes was done in two groups. Results: In preeclampsia group mean serum IMA (115.23 ± 49.51) was significantly higher as compared to the normotensive group (79.21 ± 14.35). The optimum cut off value of IMA to detect a case was 94.5 IU/ml (sensitivity 65%, specificity 87.5%, PPV 83.9%, NPV 71.4% and diagnostic accuracy of 76.3). Pre-eclamptic women, had significantly higher incidence of PTVD, lower fetal birth weight and placental histopathological changes as compared to normotensive group. 83.8% of the women with raised IMA levels were pre-eclamptic. Raised IMA levels were significantly associated with higher incidence of PTVD, birth weight ≤ 2 kg and hypoxic histopathological lesions of chorangiosis, intervillous fibrin and hyalinization. Conclusion: Determination of maternal serum IMA levels early in pregnancy can predict preeclampsia and avoid future severe preeclampsia related complications. It might be useful to optimize both maternal and fetal/neonatal outcomes.

A case of Philadelphia chromosome-positive acute myeloid leukaemia with missense mutation R132c (c.394 c>t) and single nucleotide polymorphism rs11554137(G105G) in isocitrate dehydrogenase 1 gene.

Acute myeloid leukaemia (AML) is a heterogeneous disease due to its variable clinical, morphological and genetic features. New chromosomal and molecular abnormalities are being studied to evaluate novel treatment options and prognostic implications. We report a patient with AML who was Philadelphia chromosome-positive along with IDH1R132 mutation and SNP rs11554137(IDH1105GGT). Due to limited reports regarding these aberrations in patients with AML, there is no consensus regarding their prognostic implications. To the best of our knowledge, the presence of Philadelphia chromosome, IDH1R132 and SNP rs11554137 in a single AML patient with good prognosis is a novel finding.

Synchronous occurrence of lobular breast carcinoma and granulosa cell tumor of ovary mimicking metastatic lobular breast carcinoma.

Breast cancer is one of the main sources of ovarian metastasis. Diffuse sheet of lobular carcinoma cells can strongly mimic granulosa cell tumor (GCT) which itself is a rare ovarian neoplasm constituting <5% of all the ovarian neoplasms. A 55-year-old female presented with a painful lump in the right breast associated with nipple discharge for 4 months, which on radiological and cytological findings was suspicious of an epithelial malignancy. During routine work-up, a solid-cystic lesion in the left ovarian adnexa was identified. The patient underwent right modified radical mastectomy along with left salpingo-oophorectomy. Histopathological and immunohistochemical features confirmed the diagnosis of a synchronous lobular carcinoma breast with GCT ovary. Simultaneous occurrence of Lobular carcinoma breast (LCB) and GCT ovary is extremely rare. Morphologically, these can look similar, raising a suspicion of LCB metastasis to ovary. This is important to differentiate the two for a proper patient management and prognosis.

Comparative study between liquid-based cytology & conventional Pap smear for cytological follow up of treated patients of cancer cervix.

Background & objectives: Cancer cervix is one of the most common forms of genital malignancy among Indian women. Recurrence is seen in a significant number of cases. The conventional cervical smear technique has inherent problems and screening and interpretation errors. This study was undertaken to assess the efficacy of liquid-based cytology (LBC) as a method for cytological follow up and detection of recurrence in treated cases of cancer cervix and to compare it with conventional Pap smear technique to find the best screening method for detection of recurrence in these patients. Methods: This cross-sectional study was conducted over a period of one year. Patients attending Gynecology and Radiotherapy outpatient departments for follow up after treatment of cancer cervix were included. Pap smear and LBC were taken in all cases. Colposcopy and biopsy were done for those having epithelial cell abnormality in cytology report. Colposcopy and biopsy were taken as gold standard for diagnosis of cancer cervix recurrence. Results: Ninety four treated patients of carcinoma cervix were studied. The diagnostic accuracy for detection of recurrence of conventional Pap smear was 79.16 per cent, and that of LBC was 97.6 per cent. The difference between the two methods was significant (P<0.001). Interpretation & conclusions: Our findings showed that LBC performed better than the conventional method of cytology to detect recurrence of squamous cell carcinoma. Its sensitivity, specificity as well as accuracy were much higher than conventional method. LBC can be a better method of cytological follow up of post-treated patients of cancer cervix.

Evaluation of Use of Adipose Cells in Various Procedures of Plastic Surgery and its Volumetric Quantification using High Resolution Ultrasound.

INTRODUCTION: Autologous fat transfer is based on one of the principles of plastic surgery, replace like with like. It is used in wide variety of aesthetic procedures such as lip, facial augmentation and reconstructive procedures such as involutional disorders, post traumatic defects etc. AIM: This prospective study was on the use of adipose cells in various procedures of plastic surgery, the role of high resolution ultrasound in estimating the volume of the grafted fat, comparison of the results based on the different donor sites of the harvested fat and comparison of the effectiveness of grafted fat in extremities and craniofacial region. MATERIALS AND METHODS: In this prospective study a total of 34 patients underwent fat grafting procedure at various sites of the body from May 2012 till November 2013. After noting the details of the patient, details of the defect, laboratory and radiological investigations, the consent for the fat grafting procedure was taken. Clinical photographs and High Resolution Ultrasound (HRUS) volume estimation was done on a regular basis as per the protocol. RESULTS: Out of 34 patients, 29 patients underwent free fat grafting and five patients underwent derma fat grafting. HRUS at six months revealed a mean 73.5% and 63.5% of the injected fat remained in contour deformity in extremities and craniofacial region respectively. HRUS at one year revealed a mean 57.4% and 41.4% of the injected fat remained in contour deformity in extremities and craniofacial region respectively. CONCLUSION: HRUS is an excellent handy modality for serial volume estimation, cost-effective, non-invasive, multi planar modality, does not require any preparation, and easily done outdoor procedure. Follow up is a practical proposition. Autologous fat grafting is a safe procedure with no significant complications other than fat reabsorption and it can be done under local anaesthesia in contour deformity of smaller areas. Disadvantage of autologous fat grafting is the fat reabsorption needing multiple sittings.

An Immunohistochemical Study of Anaplastic Lymphoma Kinase and Epidermal Growth Factor Receptor Mutation in Non-Small Cell Lung Carcinoma.

INTRODUCTION: Lung cancer is one of the leading causes of cancer related death. Targeted treatment for specific markers may help in reducing the cancer related morbidity and mortality. AIM: To study expression of Anaplastic Lymphoma Kinase (ALK)and Epidermal Growth Factor Receptor (EGFR) mutations in patients of Non-Small Cell Lung Cancer NSCLC, that are the targets for specific ALK inhibitors and EGFR tyrosine kinase inhibitors. MATERIALS AND METHODS: Total 69 cases of histologically diagnosed NSCLC were examined retrospectively for immunohistochemical expression of EGFR and ALK, along with positive control of normal placental tissue and anaplastic large cell lymphoma respectively. RESULTS: Of the NSCLC, Squamous Cell Carcinoma (SCC) accounted for 71.0% and adenocarcinoma was 26.1%. ALK expression was seen in single case of 60-year-old female, non-smoker with adenocarcinoma histology. EGFR expression was seen in both SCC (59.18%) and adenocarcinoma in (77.78%) accounting for 63.77% of all cases. Both ALK and EGFR mutation were mutually exclusive. CONCLUSION: EGFR expression was seen in 63.77% of cases, highlighting the importance of its use in routine analysis, for targeted therapy and better treatment results. Although, ALK expression was seen in 1.45% of all cases, it is an important biomarker in targeted cancer therapy. Also, the mutually exclusive expression of these two markers need further studies to develop a diagnostic algorithm for NSCLC patients.

Retrospective analysis of FFPE based Wilms' Tumor samples through copy number and somatic mutation related Molecular Inversion Probe Based Array.

In this report, retrospectively, we analyzed fifteen histo-pathologically characterized FFPE based Wilms' Tumor (WT) samples following an integrative approach of copy number (CN) and loss of heterozygosity (LOH) imbalances. The isolated-DNA was tested on CN and somatic-mutation related Molecular-Inversion-Probe based-Oncoscan Array™ and was analyzed through Nexus-Express OncoScan-3.0 and 7.0 software. We identified gain of 3p13.0-q29, 4p16.3-14.0, 7, 12p13.33-q24.33, and losses of 1p36.11-q44, 11p15.5-q25, 21q 22.2-22.3 and 22q11.21-13.2 in six samples (W1-6) and validated them in nine more samples (W7-9, W12-15, W17-18). Some observed that discrete deletions (1p, 1q, 10p, 10q, 13q, 20p) were specific to our samples. Maximum-LOH was observed in Ch11 as reported in previous studies. However, LOH was also observed in different regions of Ch7 including some cancer genes. The identified LOH-regions (1q21.2-q21.3, 2p24.1-23.3, 2p24.3-24.3, 3p21.3-21.1, 4p16.3, 7p11.2-p11.1, 7q31.2-31.32, 7q34-q35 and Ch 8) in W1-W6 were also validated in W7-9, W12-15 and W18. In addition, previously reported LOH of 1p and 16q region was also observed in our cases. The proven and novel onco (OG)- and tumor-suppressor genes (TSGs) involved in the CNV regions affected the major pathways like Chromatin Modification, RAS, PI3K; RAS in 14/15 cases, NOTCH/TGF-ß and Cell Cycle Apoptosis in 10/15 cases, APC in 9/15 cases and Transcriptional Regulation in 7/15 cases, PI3K and genome maintenance in 6/15 cases. This exhaustive profiling of OG and TG may help in prognosis and diagnosis of the disease after validation of all the relevant results, especially the novel ones, obtained in this research in a larger number of samples.

Evaluation of prognostic factors in medically treated patients of spinal tuberculosis.

This study was aimed to determine the prognostic factors in medically treated patients of spinal tuberculosis. In this longitudinal observational study, from July 2010 to December 2011, 70 consecutive patients (40 males and 30 females) spinal tuberculosis were enrolled. Diagnosis of spinal tuberculosis was based on characteristic clinical and neuroimaging features. Diagnosis was histopathologically and/or bacteriologically verified. Patients received antituberculous treatment as per World Health Organization guidelines and were followed for 6 months. Disability was evaluated with modified Barthel index (MBI). Outcome was defined as good (MBI > 12) and poor (MBI ≤ 12). Various clinical and neuroimaging parameters, likely to affect the outcome, were analyzed using univariate and multivariate analysis. After 6 months, 45 patients had a good outcome, while 25 patients had a poor outcome. On univariate analysis, duration of illness >6 months (OR 0.062, CI 0.018-0.212), bladder involvement (OR 0.102, CI 0.033-0.317), spinal deformity (OR 0.050, CI 0.013-0.196), spastic paraparesis (OR 0.572, CI 0.190-1.723), and flexor spasms (OR 0.077, CI 0.021-0.280) were found as important clinical predictors of poor outcome. Involvement of more than 2 vertebrae (OR 0.095, CI 0.028-0.328), complete collapse (OR 0.072, CI 0.022-0.241), cord compression (OR 0.025, CI 0.003-0.204), spinal extension of the abscess (OR 0.044, CI 0.005-0.350), and thick/septate abscess wall (OR 0.062, CI 0.016-0.240) were the neuroimaging parameters associated with poor prognosis. However, on multivariate analysis, duration of illness >6 months (Exp-b 0.086, CI 0.019-0.378), cord compression (Exp-b 0.035, CI 0.003-0348), and spinal extension of the abscess (Exp-b 0.109, CI 0.017-0.91) were significant. Medical management results in clinical improvement in a majority of the patients of spinal tuberculosis. Duration of illness >6 months, cord compression, and spinal extension of abscess are associated with poor outcome.

Ectopic tubal choriocarcinoma: a rarity.

Herein, we present a case of tubal choriocarcinoma which was diagnosed initially as chronic ectopic pregnancy. During laparotomy we noticed a haemorrhagic friable mass in the left flank, adherent to the bowel. Left-sided salpingoopherectomy was performed. Serum ß HCG (human chorionic gonadotropin) levels performed in the postoperative period were elevated. Histopathology demonstrated choriocarcinoma. She was given six cycles of chemotherapy (etoposide, methotrexate, actinomycin D-cyclophosphamide, vincristine/oncovine (EMA-CO) regime) and monitored by serial ß HCG estimation. This case highlights the importance of undertaking histopathological examination of the tubal tissue in every patient who presents with ectopic pregnancy. This important diagnostic test prevents the potential of missing this rare and highly malignant disease which is otherwise curable in most instances.

Neurothekeoma: a rare sacrococcygeal tumor in a child.

Neurothekeoma is a rare, benign, and asymptomatic tumor of the skin. Most tumors are located on the head, shoulders, and arms. It is classified as a nerve sheath tumor and epidemiologically occurs in young adults. It is rare to find this tumor in children. This report describes a case of neurothekeoma in a 10-years-old boy at an uncommon site: the sacrococcygeal region. Being an uncommon entity, it is reported with a brief review of the relevant literature.

Correlation of serum vascular endothelial growth factor with clinicopathological parameters in cervical cancer.

Angiogenesis plays an important role in cervical cancer progression. Currently among several factors known to promote angiogenesis, vascular endothelial growth factor (VEGF) is most important. To evaluate the effect of treatment on VEGF levels and their correlation with other predictive factors, pre-and post treatment levels of VEGF were estimated in cervical cancer patients. 110 cases of frank cancer and 50 controls were enrolled for the present study: 18 in Stage I, 32 in Stage II, 48 in Stage III, and 12 in Stage IV. Serum VEGF levels were estimated by ELISA in patients on the day of recruitment and post treatment follow-up at a fixed time interval of 6-8 weeks. VEGF levels were highly significant among patients as compared to controls (p = 0.001). The pre-treatment VEGF levels among different stages of the disease were marginally insignificant (p = 0.07). However, they were significantly different for (i) various grades (p < 0.001), (ii) tumor size (p = 0.026), and (iii) smoking habits (p = 0.018). Post treatment levels were highly significant, as compared to pre-treatment values (p = 0.001). The pre-treatment and post-treatment VEGF levels were associated with (i) disease stage (p = 0.002), (ii) grade (p = 0.001), and (iii) tumor size (p = 0.001). In conclusion, VEGF is a potent angiogenic factor and can be considered as an effective prognostic marker in cervical cancer.
