Accuracy, limitations and pitfalls in the diagnosis of soft tissue tumors by fine needle aspiration cytology.
S Kumar, N Chowdhury
January 2007, 50(1):42-5
PMID:17474257
The diagnosis of soft tissue tumors is one of the biggest diagnostic challenges in pathology. In this study, we attempted to measure the accuracy of FNAC in diagnosing soft tissue tumors. All the cases of FNAC with cyto-histological correlation between January 2003 and August 2005 (a total of 72 cases) were collected and sensitivity, specificity, positive and negative predictive values measured. The sensitivity and positive predictive value for differentiating between benign and malignant lesions was 0.8421, while the specificity and negative predictive value was 0.9412 for the same. The main problem was false negatives due to a borderline or low grade spindle cell sarcoma being classified as benign. However, only 18 cases could be typed precisely. Therefore, FNAC has a role in the initial diagnosis of soft tissue sarcomas, but it should be used as a complement rather than a competitor to histopathology.

CT guided fine needle aspiration cytology of thoracic mass lesions : a prospective study of immediate cytological evaluation.
A Bandyopadhyay, R Laha, Tushar Kanti Das, S Sen, S Mangal, Pradip Kumar Mitra
January 2007, 50(1):51-5
PMID:17474259
To evaluate the role of CT guided FNAC as diagnostic and supportive investigation for thoracic lesions, 190 patients were studied during two years period from March 2003 to February 2005 in our institution. A total number of 163 (85.8%) lung lesions, 22 (11.6%) mediastinal lesions and 05 (2.6%) pleural lesions were obtained; only neoplastic lesions were categorized as per WHO classification. The diagnostic sensitivity for malignancy was 97.71% and specificity 100%. Though our priority was cytological assessment, the cytological diagnosis was corroborated with clinico-radiological parameters and transbronchial biopsies whenever applicable.

Retroperitoneal ganglioneuroma with lymphnode metastasis : a case report.
R Srinivasan, K Sreedharan Koliyadan, G Krishnand, Sudha S Bhat
January 2007, 50(1):32-5
PMID:17474252
Ganglioneuroma is a benign, most differentiated tumor of neural crest origin. These tumors though benign, can very rarely metastasize to regional lymphnodes or to distant sites. We report a case of a 52 year old lady who presented to the surgical OPD with dyspeptic symptoms of 2 months duration. Ultrasonography and CT scan of the abdomen showed a homogenous mass in the region of the right adrenal gland, extending between the inferior vena cava and the aorta. A clinical and radiological diagnosis of an adrenal tumor was made. Microscopically, the tumor histology was that of a ganglioneuroma (schwannian stroma-dominant) mature type. The lymph node attached to the tumor showed metastasis, the metastatic foci having the same morphology as the primary tumor. The right adrenal gland was free of tumor. The case is illustrative due to its clinical presentation mimicking an adrenal incidentaloma, and a rare phenomenon of a benign tumor exhibiting completely differentiated lymph node metastasis.

The histopathology of chronic gastritis.
N Moorchung, AN Srivastava, NK Gupta, BR Achyut, B Mittal
January 2007, 50(1):18-24
PMID:17474248
Chronic gastritis is a multifactorial disorder thought to be influenced by bacterial and host genetic factors. Histopathological examination is the mainstay of diagnosis, however features like the presence of Helicobacter pylori are difficult to evaluate on biopsy. We evaluated 120 gastric antral biopsies using the revised Sydney system. The density of the inflammatory infiltrate, H pylori and mast cells were evaluated. It was seen that the presence of H pylori is strongly associated with an acute and a chronic inflammatory infiltrate. The presence of neutrophils on biopsy is strongly associated with the presence of H pylori and with the density and the grade of the chronic inflammatory infiltrate. The chronic inflammatory response is an intermediary between the acute inflammatory process and glandular atrophy. The lymphocytic infiltrate is also a precursor lesion of the lymphoid follicles. The presence of mast cells does not appear to be related to any of the other inflammatory parameters. The presence of one feature is a strong indicator for the presence of other inflammatory features.

Pattern of chromosomal abnormalities in adult acute lymphoblastic leukemia.
S Khalid, M Usman, Salman Naseem Adil, A Ayub, M Khurshid
January 2007, 50(1):78-81
PMID:17474268
OBJECTIVES: To study the pattern of chromosomal abnormalities in adult patients with acute lymphoblastic leukemia. STUDY DESIGN: A retrospective study. Place and duration of study: January 1998 to June 2005 at the Cytogenetics department, Aga Khan University Hospital, Karachi. PATIENTS AND METHODS: A retrospective analysis of cytogenetic studies was carried out in patients who were diagnosed as ALL and were more than 15 years of age. Cytogenetic analysis was performed using a trypsin-Giemsa banding technique. Karyotypes were interpreted using International System for Cytogenetics Nomenclature (1995) criteria. RESULTS: The requests were received for cytogenetic analysis of bone marrow specimens in 69 patients who were diagnosed as ALL. Cytogenetic results were available in 62 patients; out of which 51 were males and 11 were females. 44 patients (70%) were found to have a normal karyotype. In 18 patients (29%), abnormal karyotype was found. CONCLUSION: Cytogenetic studies should be part of the initial work up of every patient with ALL. Larger scale studies will help refine our understanding of the less common chromosomal patterns and conduct multivariate analysis to define the relative prognostic value of karyotypic results.

HFE mutation H63D predicts risk of iron over load in thalassemia intermedia irrespective of blood transfusions.
V Sharma, I Panigrahi, P Dutta, S Tyagi, Ved Prakash Choudhry, R Saxena
January 2007, 50(1):82-5
PMID:17474269
Iron overload is a well-documented complication in thalassemia intermedia. Moreover, it is seen that the number of blood transfusions received does not correlate with the degree of overload. Since, HFE gene is associated with iron overload; the present study was conducted in an attempt to evaluate its role in thalassemia intermedia. The subjects were consecutive thalassemia intermedia cases attending the Hematology outpatient clinic. Controls were healthy hospital staff with negative family history of hemolytic anemia or liver disease. The molecular analysis for HFE mutations H63D and C282Y were done with primers described earlier. ELISA was used to measure serum ferritin. Sixty-three patients of thalassemia intermedia including 48 beta-homozygous/heterozygous thalassemia intermedia and 15 HbE-beta-thalassemia were studied. Six (12.5%) of the former and two (13.3%) of the latter were heterozygous for H63D; one of which, a 51-year old male also had clinical features of hemochromatosis. In healthy controls, prevalence of H63D heterozygosity was 7.5% (6/80). An interesting feature observed was that though the age and transfusions taken were similar in both groups, the serum ferritin greater than 500 ng/dl were observed in all patients (100%) with HFE mutation whereas it was seen in 12/42 (28.6 %) of patients without the mutation (p = 0.002). Thus, it is concluded that thalassemia intermedia patients with co-existent HFE mutation have a higher likelihood of developing iron overload and may require early iron chelation.

G Viswanath, Praveen, AR Hanumanthappa, NR Chandrappa, C Baragundi Mahesh
January 2007, 50(1):97-100
PMID:17474275
Bacterial meningitis is an important and frequent devastating disease. The present study was carried out to determine the prevalence of pyogenic meningitis in our hospital in children and to find out the sensitivity of Gram stain, CRP and latex agglutination tests for the diagnosis of pyogenic meningitis from CSF sample. Out of 150 CSF samples studied, 40 were diagnosed as pyogenic meningitis. H. influenzae was the commonest organism (22.5%), followed by Streptococcus pneumoniae 15%, Staphylococcus aureus--10%, Acinetobacter species and coagulase negative Stapylococci 7.5% each, E-coli 5%, and a case each of Klebsiella species, Group B streptococci, Proteus, Pseudomonas and Enterococci. The sensitivity of Gram stain and Latex agglutination test was 90% and that of CRP test was 62.5%. As most of the cases included in our study were treated earlier, the culture positivity was only 62.5%. Hence, Gram stain and/or latex agglutination tests, if done properly are most rapid and reliable tests for the diagnosis of pyogenic meningitis.

Granulocytic sarcoma in the absence of acute myeloid leukemia : a case report.
S Khalid, Salman Naseem Adil, Irfan Ahmed Vaziri
January 2007, 50(1):88-90
PMID:17474271
Granulocytic sarcoma is an extramedullary tumor composed of immature granulocytic precursor cells. The most common sites of presentation are bone, periosteum, soft tissue, lymph node, skin, and infrequently small intestine. The tumor may develop during the course of acute myeloid leukemia, chronic myeloid leukemia or other myelodysplastic disorders. It can occur without blood or bone marrow manifestations of leukemia and in this case, the diagnosis is difficult. Our patient was initially diagnosed as a case of T-cell non Hodgkin's lymphoma and received one cycle of CHOP with only transient improvement in his symptoms. Subsequently, his biopsy slides were reviewed at our centre and were reported as granulocytic sarcoma.

S Singh, R Gupta, S Nigam, N Khurana, Satish Kumar Aggarwal, K Uma Chaturvedi, Ashish Kumar Mandal
January 2007, 50(1):6-10
PMID:17474245
Renal dysplasia is one of the major renal developmental anomaly characterized by abnormal structural organization and development of metanephric elements. It is usually detected antenatally or in early childhood. The kidney may be multicystic, aplastic, hypoplastic or duplex. We studied 22 cases of cystic renal dysplasia diagnosed over a period often years to identify the spectrum of morphological changes in dysplastic kidney, with special emphasis on mesenchymal changes. Clinical, radiological and gross morphologicalfeatures were noted. Microscopic features were studied in detail, including the epithelial and mesenchymal changes. Twenty-one of the 22 cases studied were children. One case was a 21-year-old adult, which is a rare age at presentation. Male to female ratio was 1.1:1. One of our patients had contra-lateral ureteric stenosis, a rare anomaly reported with renal dysplasia. Ten patients, all autopsy cases, had multi-system congenital anomalies. As cystic renal dysplasia is not a hereditary disease, it must be differentiated from polycystic kidney disease. Other differential diagnoses are cystic nephroma and cystic partially differentiated nephroblastoma. Histopathological examination is the final diagnostic tool since radiological features alone may not be sufficient to exclude other cystic renal lesions. Cartilage may not be seen in all cases of renal dysplasia. Once diagnosed, other associated anomalies should also be looked for.

Pseudoglandular pattern of basaloid cells in pilomatrixoma in the needle aspiration cytology : a case report.
N Siddaraju, MM Mishra, SK Roy, MM Bundele, S Jayanthi
January 2007, 50(1):63-5
PMID:17474263
A varied cytomorphology of pilomatrixoma often results in diagnostic dilemma. Here, we report a case of pilomatrixoma that presented with prominent gland like arrangement of basaloid cells on cytologic smears causing diagnostic problem. Clinical diagnosis in the present case was cervical lymphadenitis and the cytologic smears showed a strikingly varied morphology with few loose clusters of basaloid cells exhibiting pseudoglandular pattern. A possibility of metastatic carcinoma was considered. However, following histopathologic diagnosis of pilomatrixoma, when cytologic smears were reviewed, it was realized that the ghost cells were overlooked as anucleate squames. Our case highlights the importance of careful clinical and cytologic interpretation of pilomatrixoma. Awareness of the cytomorphologic characteristics of ghost cells and their identification in cytologic smears is highly criticalfor an accurate diagnosis. A prominent basaloid cell component of pilomatrixoma with a pseudoglandular pattern, which has not been described earlier, may easily lead to a false positive diagnosis.

Bacteriological evaluation of conjunctiva, contact lens storage cases and solutions during contact lens wear.
V Prabha, N Singh, P Chopra
January 2007, 50(1):101-3
PMID:17474276
A total of 90 subjects were investigated in this study, out of which 51 constituted the contact lens wearing group and 39 constituted the control group who had never worn contact lenses. Out of 51 contact lens wearing group, 41 were asymptomatic lens wearer subjects and 10 were symptomatic lens wearer subjects having some complications. All the subjects of contact lens wearing group had worn soft contact lenses on daily wear basis for a duration of 7 days to one year. In total 33 subjects were culture positive and remaining 57 culture negative. Staphylococcus epidermidis was isolated equally from asymptomatic and control group, however, significantly more gram negative organisms such as Pseudomonas aeruginosa and Serratia marcescens were isolated from the symptomatic lens wearers. P. aeruginosa and S. marcescens could also be isolated from lens storage cases. S. marcescens was the organism most commonly isolated from the contact lens solutions. Further, the results showed that both P. aeruginosa and S. marcescens adhere to injured cornea only and not to normal cornea when microscopic study of adherence of bacteria to uninjured and injured ex vivo mouse corneas was done.

Santosh Kumar Mondal, Ashit Kumar Ghosh
January 2007, 50(1):11-4
PMID:17474246
Enucleation or complete removal of eye is considered to be a mainstay of therapy for many end-stage diseases of eye. We aimed to determine the frequency and indications for enucleations perfomed at a tertiary care hospital in eastern India. A total of 150 enucleated eyes from 146 patients were analyzed. The formalin fixed paraffin embedded sections of all enucleated eyes were examined microscopically and histopathological analysis was done. In the present series, malignant tumours were most frequent indication of enucleation (64%) followed by ocular inflammation (14.7%), staphyloma (6.7%), trauma (5.3%), painful blind eye due to glaucoma (4%). Retinoblastoma, a malignant tumour emerged as commonest indication (52%). Three major indications for enucleation were malignant tumours, ocular inflammation and staphyloma altogether 92%. Malignant melanoma though commonest ophthalmic tumour requiring enucleation in many parts of the world was not very common in our studies comprising 18.7% of all malignant tumours.

Role of p53 and bcl2 as markers of vitamin A response in premalignant lesions of the oral cavity.
D Varma, S Gupta, AK Mandal
January 2007, 50(1):15-7
PMID:17474247
Oral cancer accounts for 40 to 50% of cancers diagnosed in India. Oral cancer is preceeded in most cases by pre malignant lesions-leukoplakia, submucous fibrosis and lichen planus. Stoppage of causative agents reverts premalignant lesions in some of the cases only. Thus anti oxidant therapy is being used to revert premalignant change to normal. Few studies available, have taken clinical parameters as indicators of response to therapy. Extensive medline search failed to reveal any study at the cellular level. This study attempts to investigate for the first time the role of p53 and bcl2 as markers of prognosis following vitamin A therapy. 24 cases of pre malignant lesions of oral cavity were studied. 1 lakh IU of vitamin A were given orally twice a week for 3 months. Biopsies were done before and after therapy. Haematoxylin and Eosin stain was done to confirm diagnosis. Immunostaining for mutant p53 and bcl2 was done on paraffin sections. 500 cells were counted over an average of 5 HPF and percentage positivity was calculated. Statistical analysis was done by applying the paired t tests. In 19 cases (79.2%) of premalignant lesions mutant p53 expression was zero before therapy, and remained unchanged even after the therapy. 3 cases (12.5%) had high mutant p53 values which reduced following therapy (p = 0.037). Therapy thus proved effective in these cases. However, in 2 cases (8.3%) pre therapy values of zero showed an increase after vitamin A therapy. These were the cases which had dysplasia and were chronic smokers. In 2 cases (8.3%) pre therapy values of bcl2 were zero and remained unchanged even after therapy and these cases did not stop smoking even during the vitamin A therapy. In 12 cases (50.0%) higher pre therapy values were reduced after therapy (p < 0.0001). Vitamin A therapy was effective in these cases. However, in 10 cases (42.0%) expression of bcl2 increased subsequent to therapy. Therapy failed in these cases because of chronic heavy smoking and tobacco chewing. Thus, in the majority of cases vitamin A was effective in preventing mutation of p53 (91.7%) and expression of bcl2 (58.0%). In effect, these two oncoproteins can be used as prognostic markers and follow up for anti oxidant therapy.

S Shah, K Shukla, P Patel
January 2007, 50(1):56-8
PMID:17474260
The aim of this study was to assess the usefulness of fine needle aspiration cytology (FNAC) as a diagnostic method in lung tumour as well as to determine the incidence of lung cancer in various age and sex group and in relation with smoking. Hundred cases of lung tumours were investigated. Out of 100 patients, 88 were male and 12 were female. The age of patients varies from 23-78 years most of the patient were in the age group of 50-70 years. The most common tumour was squamous cell carcinoma (45%) followed by adenocarcinoma (22%), small cell carcinoma (16%) and large cell carcinoma (8%). Eighty out of 100 patient had history of smoking. Diagnostic accuracy of cytology with final histopathological report was established with accuracy rate of 95%.

Diagnosis and grading of non-Hodgkin's lymphomas on fine needle aspiration cytology.
S Mathur, R Dawar, K Verma
January 2007, 50(1):46-50
PMID:17474258
Fine needle aspiration cytology (FNAC) enjoys popularity among clinicians worldwide, as a first line of investigation in all patients with lymphadenopathy and is preferred over biopsy because of its minimally invasive nature and cost-effectiveness. Although non-Hodgkin's lymphomas (NHL) are conventionally diagnosed and graded on biopsy specimens, it may be useful to be able to not only diagnose but also grade these cases on FNAC smears. The WHO and REAL classifications forming the basis of treatment in some centres rely on clinical features, immunocytochemistry and cytogenetics, which are beyond reach of most centres in the developing countries. This study therefore is aimed at diagnosing and grading NHLs on morphological parameters. The cytologic grading accuracy is compared with the histologic grades assigned according to the International Working Formulation (IWF) system which relies solely on morphological features, most important of which is cell size. Ninety five cases were retrieved over a 3 year period (May 2000 to April 2003). These were (i) cases where a cytological diagnosis of NHL or suspicious of NHL was made and corresponding histological sections available and (ii) cases where a diagnosis of NHL was made in histology and corresponding FNAC smears were available irrespective of the cytological diagnosis. The diagnostic accuracy of FNAC for NHLs was determined using histology as the gold standard. Cases were also graded on FNAC smears using a three tier grading system based upon cell size into low, intermediate and high grades. Cytologically assigned grades were correlated with the corresponding histological grades (IWF) to determine grading accuracy. An accurate diagnosis of NHL was thus possible in 67/95 (70.5%) cases. Overall accurate grading was seen in 65/95 (68%) cases using cytological criteria. Accurate cytologic grading was possible in 14/15 (93.33%) low grade, 11/18 (61.11%) intermediate and 40/62 (64.5%) high grade non Hodgkin's lymphomas. Kappa statistics revealed a very good agreement between cytological and histological grades for low grade NHL. The kappa scores for intermediate and high grade NHLs indicated moderate agreement. Using the two-tier system grading the kappa value for high grade lymphomas improved to 0.72, indicating good concordance. This study highlights the utility of FNAC as a morphological tool for diagnosing and grading NHLs in a significant number of cases. This modality may assist clinicians in management of cases of NHLs, especially in centres working within the constraints of limited availability or non availability of ancillary techniques.

A Mishra, Samir Kumar Behera, A Choudhary, D Mishra, B Behera
January 2007, 50(1):59-60
PMID:17474261
Yolk sac tumor is the second most common germ cell tumor of the ovary. A nine year old female child presenting with a lower abdominal mass diagnosed as a yolk sac tumor on fine needle aspiration cytology (FNAC) is described. Ultrasonographically (USG) guided FNAC of the lesion revealed tight clusters and papillary fronds of cells associated with homogeneous acellular eosinophilic bodies. A preoperative diagnosis of this tumor is helpful in planning further diagnostic and therapeutic steps.

Optimization of a polymerase chain reaction (PCR) for increasing its sensitivity to detect Chlamydia pneumoniae specific genome.
J Malathi, G Shyamala, V Feeba, K Lily Therese, HN Madhavan
January 2007, 50(1):104-6
PMID:17474277
Being an intracellular parasite, Chlamydia pneumoniae disseminates to organs outside the respiratory tract and causes chronic diseases in human. Nucleic acid-based method such as polymerase chain reaction (PCR) as diagnostic test has greater sensitivity and specificity than conventional microbiological techniques. The PCR protocol consisting of touchdown technique to detect C. pneumoniae DNA using major outer membrane protein gene (MOMP) was carried out in our laboratory as described in reference paper, but analytical sensitivity reported in it was not reproducible. Hence, the PCR was optimized after modifications in annealing temperature and magnesium ion concentrations. First round PCR profile with annealing at 56 degrees C for 8 cycles followed by 32 cycles with annealing temperature maintained at 54 degrees C and second round profile modified with annealing temperature maintained at 49 degrees C had resulted in 3-fold increase in clinical sensitivity. The present work highlights the importance of optimization of PCR in laboratory settings.

R Bharadwaj, S Pradhudesai, N Patkar, R Badhwar, NA Jambhekar
January 2007, 50(1):29-32
PMID:17474251
Peripheral neuroepithelioma of the soft tissues is an uncommon member of primitive neuroectodermal tumors. Divergent differentiation and polyphenotypia is known in peripheral neuroepithelioma. We report one such recurrent peripheral neuroepithelioma in an infant which was detected at one month of age, in the foot. Microscopically, it showed tumor cells in nests and lobules with abundant Homer-Wright rosettes. Immunohistochemically, tumor cells were immunoreactive for neural markers but also displayed an aberrant myoid phenotype. The prognostic implications of this anomalous phenotype are unclear as of now, but documentation of this is necessary for possible future references.

Fine needle aspiration cytology of breast carcinoma with neuroendocrine features--a case report with histopathological and immunohistochemical correlation.
K Mardi, J Sharma
January 2007, 50(1):65-8
PMID:17474264
Cytohistological and immunohistochemical features of a rare case of breast carcinoma with diffuse neuroendocrine features occurring in an elderly female patient is reported. Cytology demonstrated predominantly single and loose clusters of monomorphic plasmacytoid tumor cells that possessed moderate amounts of basophilic cytoplasm with eccentrically placed nuclei. These cells were also showing conspicuos rosette like formations. Histological examination showed a typical endocrine pattern with organoid nests and ribbons of well differentiated monomorphic cells with frequent pseudorosette formation resembling carcinoid tumor of gastrointestinal tract. Neuroendocrine differentiation was confirmed by immunohistochemical positivity for neuron specific enolase, synaptophysin and chromagranin.

Presence of Hb S in Uttaranchal.
PK Shukla, S Upadhyay, B Kumar, N Thapliyal, SR Saxena, D Joshi
January 2007, 50(1):70-4
PMID:17474266
Haemoglobin-S has been reported in several studies on remote populations from various parts of India eg Maharashtra, Madhya Pradesh, Andhra Pradesh, Orissa, West Bengal, Rajasthan and Malaysian Indians. Uttaranchal also has got scattered areas with people living in remote-pockets due to its geophysical nature. There has been no previous report from this state about prevalence of Hb-S. In the present study on 38 individual eight were found to have Hb-S positivity by sickling test. In one of these electrophoretic confirmation was positive with demonstration of associated Beta thalassaemia. The group was a family of muslims in village Baghori near Haldwani. Due to technical, geographical and social restrictions further study could not be done. However, this study does establish the presence of Hb-S-Beta thalassaemia in Uttaranchal State for the first time. Follow up study in the affected area and elsewhere in the state might discover more of Hb-S positivity, other haemoglobinopathies and thalassaemias.

Immunophenotypic patterns in precursor T-cell neoplasm.
R Gupta, S Naseem, R Kashyap, S Nityanand
January 2007, 50(1):75-7
PMID:17474267
T-cell lymphoproliferative disorders are a heterogeneous group of lymphoid neoplasm that can mimic both benign conditions and non-hematopoietic tumors. In routine clinical practice, morphology and immunophenotyping forms the basis of their diagnosis. In this retrospective analysis, we evaluate the utility of flow cytometric immunophenotyping patterns in diagnosis of precursor T-cell neoplasm. Aberrant expression of T-cell antigens was found in all the cases of precursor T-cell neoplasm. The residual normal T-lymphocytes, identifiable in majority of cases, were found to be useful in evaluation of quantitative differences in antigen expression by leukemic cells. A careful analysis of flow cytometric immunophenotyping data can provide additional information which is useful for diagnosis of precursor T-cell neoplasm. This information can be further utilized for analysis of minimal residual disease in these tumors.

Plasma cell leukemia is a rare form of malignant plasma cell dyscrasia. It can occur as a primary form without prior evidence of multiple myeloma or as a secondary form which is a terminal event in multiple myeloma. A case of primary plasma cell leukemia presenting as acute renal failure is reported here.

Induction of resistance to fluoroquinolones in clinical and environmental isolates of Pseudomonas aeruginosa.
S Vishnu Prasad, M Ballal, PG Shivananda
January 2007, 50(1):94-6
PMID:17474274
An attempt to induce resistance to ciprofloxacin in vitro was made against clinical and environmental isolates of Pseudomonas aeruginosa. This in vitro manipulation of strains resulted in the increase of minimum inhibitory concentration from 0.4 microg/ml to 1 microg/ml of the original strains to 9.0 to 12.5 microg/ml indicating development of resistance to ciprofloxacin and a major decrease in the size of zone diameters of norfloxacin and ofloxacin indicating cross resistance to these agents. Results indicate the induced resistance to ciprofloxacin can promote development of cross resistance to other fluoroquinolones. This suggests that caution should be taken while using fluoroquinolones for the treatment of Pseudomonas aeruginosa infections.

Genomics and proteomics in neoplasia.
Jan P Baak, H Mohan
January 2007, 50(1):1-5
PMID:17474244
Genomics (the study of the human genome) and Proteomics (analysis of the protein complement of the genome) are increasingly useful in e.g. diagnosis, early cancer detection, prognostication, therapy response prediction, and others. To avoid recent disappointments, -omic tests should always be carefully confirmed in independent prospective validation studies. Unfortunately, molecular oncology services often run without pathologists, although unique pathobiologic knowledge often can be essential to get the best information. Strategic choices should be made which diseases/organ sites be analyzed and techniques used. Pathologists should quickly familiarize themselves with both -omic techniques and applications, thereby going beyond the usual pathology boundaries.
