Of eight human herpesviruses (HHVs), often, only herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) find mention in medical literature as both of these viruses are commonly associated with genital lesions and oral ulcers, commonly known as cold sores. However, role of human herpesviruses as copathogens and in aggravation and in the transmission of other human diseases, especially the Acquired immunodeficiency syndrome (HIV/AIDS) has only very recently been recognized. Therefore, screening and treating subclinical HHV infections may offer slowing of HIV infection, disease progression, and its transmission. Beside HSV-1 and HSV-2, HHV-3 a causative agent of herpes zoster remained one of the first manifestations of HIV disease before the era of highly active antiretroviral therapy (HAART). HHV-5 also known as human
Cytomegalovirus
infection remains a significant risk factor for HIV-associated mortality and morbidity even in HAART era. It is proposed that
Cytomegalovirus
viremia could be a better predictor of HIV disease progression than CD4+ T-lymphocyte count. The role of HHV-4 or Epstein–Burr virus and HHV-6, HHV-7, and HHV-8 is still being investigated in HIV disease progression. This review provides insight into the current understanding about these 8 HHVs, their co-pathogenesis, and role in HIV/AIDS disease progression. The review also covers recent literature in favor and against administering anti-HHV treatment along with HAART for slower AIDS progression and interrupted sexual transmission.

PMID
:27013808
Introduction:
Most cytology laboratories in all Gulf countries including Oman, use the standard papanicolaou (PAP) method to stain various cytological specimens. The aim of this study was to investigate the possible application of ultrafast PAP (UF-PAP) method in cytology laboratory.
Materials and Methods:
Samples from 46 patients containing 26 body fluids and 20 fine needle aspirations (FNAs) (9 thyroids and 11 breasts) were collected. Two air dried and two wet smears from each sample were prepared and stained by UF-PAP and the standard PAP stains, respectively. Background, nuclear staining, cell morphology, and overall staining were independently reviewed by two cytoscreeners.
Results:
In all cases of FNA, UF-PAP stain gave a good score for the background, nuclear staining, cell morphology, and overall staining when compared with the standard PAP method. Although the correct diagnosis was made in all cases of body cavity fluids cases except in one case, UF-PAP stain gave a fewer score in the assessment of body cavity fluid samples.
Conclusion:
The findings of this study support the use of UF-PAP method in cytology laboratory with a high emphasis on FNA samples.

Aeromonas
spp.: An emerging nosocomial pathogen
Priyam Batra, Purva Mathur, Mahesh C Misra
January-June 2016, 8(1):1-4
DOI
:10.4103/0974-2727.176234
PMID
:27013806
Aeromonads
are hallophillic, nonacid fast, nonspore forming, Gram-negative rods which are widely distributed in the soil, foodstuffs, and aquatic environment. Since times immemorial, they are important zoonotic pathogens of poikilotherms but are now emerging as important human pathogens. These emerging enteric pathogens flourish in the water distribution system by forming biofilms. They possess large number of virulence factors including inherent resistance to various antibiotics and ability to form biofilms using quorum sensing. These properties make them easy pathogens for human infections.
Aeromonads
are important enteric pathogens, but, with the growing level of immunosuppression in the population, they have been associated with various extraintestinal infections, such as skin and soft-tissue infections, traumatic wound infections, and lower respiratory tract/urinary tract infections. The average annual incidence of bacteremia in Southern Taiwan due to
Aeromonas
spp. was 76 cases/million inhabitants between 2008 and 2010. However, the incidence reported from Western countries is much lower. The case fatality rate among patients with
Aeromonas
bacteremia ranges from 27.5 to 46%.
Aeromonads
are universally resistant to the narrow-spectrum penicillin group of antibiotics such as penicillin, ampicillin, carbenicillin, and ticarcillin. They are however susceptible to piperacillin, azlocillin, second and third generation cephalosporins, and carbapenems. Most of the
Aeromonas
species are susceptible to aminoglycosides, tetracycline, chloramphenicol, trimethoprim-sulfamethoxazole, quinolones, and monobactams. This manuscript is a comprehensive systematic review of the literature available on
Aeromonas
spp.

Presence of concurrent derangements of liver function tests in type 2 diabetes and their relationship with glycemic status: A retrospective observational study from Meghalaya
Kaustubh Bora, Meghna Borah, Happy Chutia, Chandan Kumar Nath, Dulmoni Das, Alice Abraham Ruram
January-June 2016, 8(1):30-35
DOI
:10.4103/0974-2727.176227
PMID
:27013810
Background and Objectives:
The liver plays a pivotal role in carbohydrate metabolism. Therefore, functional state of the liver in patients with diabetes is of interest. The objectives of the current study were to (i) identify co-existent biochemical derangements of liver function tests (LFTs) in type 2 diabetes and (ii) determine the association between liver function parameters and glycemic status in type 2 diabetics from Shillong, Meghalaya.
Materials and Methods:
Data from 320 type 2 diabetes patients were screened retrospectively for abnormalities in LFTs. Relationship of fasting serum glucose was assessed with the following tests in the LFT panel: Total bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and albumin. Correlation coefficient was computed between individual LFT and fasting glucose status. These bivariate analyses were supplemented by multivariate linear regression analyses.
Results:
71.25% subjects had an abnormality in at least one LFT. Elevated ALT (46.8%) and elevated ALP (48.5%) were the most common abnormality in males and females, respectively. ALP correlated positively with fasting glucose in both sexes. AST, ALT, and ALP were found to be independent determinants of glycemic status.
Conclusion:
Derangements in liver function are widely co-existent in type 2 diabetics from Shillong. Deranged liver enzymes are associated with glycemic status. Screening for liver dysfunction in diabetics and subsequent workup may lead to the identification of hepatic co-morbidities and better management.

Prevalence of Beta-Hemolytic Streptococci Groups A, C, and G in Patients with Acute Pharyngitis
Trupti B Naik, Shobha D Nadagir, Asmabegaum Biradar
January-June 2016, 8(1):45-49
DOI
:10.4103/0974-2727.176235
PMID
:27013813
Context:
Group A beta-hemolytic streptococci (GAS) is the most frequently isolated pathogen in acute pharyngitis. However, the role of Group C (GCS) and Group G (GGS) streptococci in disease burden is under recognized. The present study is carried out to find out the prevalence of acute pharyngitis caused by the different serogroups of streptococci and antibiotic susceptibility pattern of these streptococcal isolates.
Study and Design:
A cross sectional study.
Materials and Methods:
A total of 218 throat swabs from patients with acute pharyngitis and 82 from healthy controls were collected and processed as per standard protocol. Samples were inoculated on blood agar and
Streptococcus
selective agar. Isolates were identifi ed by the conventional method and serogrouped by latex agglutination test using Remel Streptex kit.
Results:
Beta-hemolytic streptococci (BHS) were isolated from 34 (15.59%) of pharyngitis patients and 11 (13.41%) of the healthy carrier. Among pharyngitis, GAS was isolated from 20 (9.17%), GCS 7 (3.21%), and GGS 7 (3.21%) patients. Carriage rate of GAS was 6 (7.31%) and GCS, 5 (6.09%). Vancomycin (100%), amoxyclavulanic acid (90%), levofloxacin (85%), and cephotaxime (80%) were found to be most effective antibiotics. Comparatively, higher drug resistance was observed among GCS and GGS to all the drugs used in the study except for levofloxacin.
Conclusions:
Although rate of pharyngitis associated with GCS and GGS is marginally lower than GAS, their carriage rate among healthy and relative higher drug resistance emphasizes the need for periodic surveillance of infection by the different serogroups of BHS.

Community acquired enterococcal urinary tract infections and antibiotic resistance profile in North India
Varun Goel, Dinesh Kumar, Rajendra Kumar, Purva Mathur, Sarman Singh
January-June 2016, 8(1):50-54
DOI
:10.4103/0974-2727.176237
PMID
:27013814
Background:
Urinary tract infections (UTIs) remain a major problem both in hospitalized and outdoor patients. Multidrug-resistant enterococci are emerging as a major nosocomial pathogen with increasing frequency. However, the incidence of community-acquired enterococcal infections and species prevalent in India is not thoroughly investigated.
Objectives:
This study aims to estimate the burden of community-acquired UTIs seen at a tertiary care hospital and to identify the
Enterococcus
species isolated from these patients. The study also aims to determine the antibiotic susceptibility pattern with reference to high-level aminoglycosides and vancomycin.
Materials and Methods:
Semi-quantitative cultures from a total of 22,810 urine samples obtained from patients seen at various Outpatient Departments were analyzed. From them 115 nonduplicate isolates of enterococci were obtained as significant pure growth (>10
5
cfu/ml) and speciated. Antibiotic susceptibility was performed by Kirby–Bauer disc diffusion method. Vancomycin resistance screening was performed by the vancomycin screen agar method recommended by Clinical and Laboratory Standards Institute and confirmed by determination of minimum inhibitory concentration by agar dilution method.
Results:
Of 115 enterococcal isolates, 61 were identified as
Enterococcus faecalis
, 42 as
Enterococcus faecium,
3 each as
Enterococcus dispar,
and
Enterococcus pseudoavium
. High-level gentamicin resistance (HLGR) was higher in
E. faecium
(47.6%) than
E. faecalis
(32.7%) and HLSR also showed the same pattern with 47.6% and 27.9% resistance, respectively. Vancomycin resistant enterococci accounted for 11.3% of the isolates, and out of them 53.8% were
E. faecium
by agar dilution method.
Conclusion:
High rate of resistance to antibiotics of penicillin group and aminoglycosides was observed in our tertiary care hospital even in community acquired UTIs. Hence, there is an urgent need for more rational and restricted use of antimicrobials.

Vandana Varma, Meena Varma, Amit Varma, Ravindra Kumar, Anuradha Bharosay, Savita Vyas
January-June 2016, 8(1):25-29
DOI
:10.4103/0974-2727.176230
PMID
:27013809
Background:
This study was undertaken to evaluate and establish the role of total sialic acid (TSA) and highly sensitive C-reactive protein (hs-CRP) in type 2 diabetes mellitus (T2DM) and its correlation with complications such as diabetic nephropathy.
Materials and Methods:
One hundred fifty-seven patients with T2DM with nephropathy (DN) and 162 patients of T2DM without nephropathy (DM) along with 165 unrelated age and sex-matched healthy controls were included in the study. Serum glucose (fasting and postprandial) levels, renal profile, and lipid profile were done as per standard protocol. Serum TSA test levels and hs-CRP level were evaluated using thiobarbituric acid assay and immunoturbidimetric method respectively.
Results:
We observed a higher concentration of serum TSA (82.67 ± 6.63 mg/dl) and hs-CRP (3.2 ± 1.44 mg/L) in diabetic nephropathy than the diabetes mellitus group (73.83 ± 6.90 mg/dl and 2.07 ± 1.32 mg/L, respectively). Both TSA and hs-CRP levels were found significantly correlated with fasting and postprandial blood sugar, hemoglobin A1c, and urine microalbumin levels in both DM and DN groups. Multinomial logistic regression analysis showed that both TSA and hs-CRP was independently associated with diabetic nephropathy.
Conclusion:
High serum TSA and hs-CRP levels may increase the microangiopathic (diabetic nephropathy) complications of T2DM.

Evaluation of SD BIOLINE Syphilis 3.0 for rapid diagnosis of syphilis: Report from a regional sexually transmitted infection reference laboratory in North India
Bhanu Mehra, Sonali Bhattar, Shikhar Saxena, Deepti Rawat, Preena Bhalla
January-June 2016, 8(1):36-40
DOI
:10.4103/0974-2727.176239
PMID
:27013811
Background:
Serology is considered the mainstay of syphilis diagnosis. The limitations of the traditional serological methods and the advent and availability of novel immunochromatographic assays have led to the widespread application of rapid point-of-care procedures as screening tools for syphilis. However, these tests have not been extensively evaluated. This study was designed to evaluate the performance of a rapid syphilis diagnostic test known as SD BIOLINE Syphilis 3.0 (SD Biostandard Diagnostics Private Limited, Gurgaon, Haryana, India).
Materials and Methods:
A panel comprising of 50 venereal disease research laboratory reactive and 50 nonreactive sera was tested using SD BIOLINE Syphilis 3.0. The performance of the test was evaluated using IMMUTREP
Treponema pallidum
hemagglutination assay (TPHA) (OMEGA Diagnostics Limited, Scotland, United Kingdom) as the reference standard and sensitivity, specificity, and negative and positive predictive values were calculated.
Results:
The sensitivity, specificity, and positive and negative predictive values of SD BIOLINE Syphilis 3.0 were 92.86% (confidence interval of 95%: 80.52–98.50%), 98.28% (90.76-99.96%), 97.50% (86.84–99.94%), and 95.00% (86.08–98.96%), respectively, compared to TPHA as the gold standard.
Conclusion:
Keeping in view the high sensitivity and specificity of SD BIOLINE Syphilis 3.0, we conclude that the test can be used as a tool for rapid on-site diagnosis of syphilis and as an alternative to TPHA for detection of antibodies to
Treponema pallidum
.

Subependymal giant cell astrocytoma (SEGA) is a low grade (WHO Grade I) tumor, usually seen in patients with tuberous sclerosis complex and commonly occurs at a lateral ventricular location. Intraoperative squash cytologic features can help in differentiating SEGA from gemistocytic astrocytoma (GA), giant cell glioblastoma and ependymoma, in proper clinical context and radiological findings, which may alter the surgical management. Here, we present a case of SEGA with squash cytologic findings and a review of cytology findings of SEGA presently available in the literature. Loose cohesive clusters of large polygonal cells containing an eccentric nucleus, evenly distributed granular chromatin, distinct to prominent nucleoli, and moderate to the abundant eosinophilic cytoplasm in a hair-like fibrillar background are the key cytologic features of SEGA. Other important features are moderate anisonucleosis and frequent binucleation and multinucleation. The absence of mitoses, necrosis, and vascular endothelial proliferation are important negative features. Other consistent features are cellular smears, few dispersed cells, few spindly strap-like cells, rare intranuclear cytoplasmic inclusion, and perivascular pseudorosettes.

PMID
:27013817
The thyroglossal duct cysts (TGDCs) are the most common congenital anomaly of the thyroid, usually manifested as painless midline neck mass. Malignancy is very rare and is reported in around 1% of cases as an incidental finding after histopathological evaluation of resected cyst. Papillary carcinoma is the most common carcinoma reported in TGDC. Here, we report a case of 17-year-old-female, who presented with a gradually increasing midline neck mass which moves with swallowing. On imaging a diagnosis of infected TGDC was made. The Sistrunk operation was done and a diagnosis of primary papillary carcinoma arising in a TGDC was rendered histopathologically. The contemporary appearance of papillary carcinoma thyroid was reported in about 20% cases of TGDC carcinoma, thus it is essential to differentiate primary papillary carcinoma arising in a TGDC from those of metastatic papillary carcinoma thyroid by strict diagnostic criteria.
