Neurobrucellosis presenting as an intra-medullary spinal cord abscess

BACKGROUND

Of the diverse presentation of neurobrucellosis, intra-medullary spinal cord abscess is extremely rare. Only four other cases have been reported so far. We present a case of spinal cord intra-medullary abscess due to Brucella melitensis.

CASE PRESENTATION

A forty-year-old female presented with progressive weakness of both lower limb with urinary incontinence of 6 months duration. She was febrile. Neurological examination revealed flaccid areflexic paraplegia with T10 below sensory impairment including perianal region. An intramedullary mass was diagnosed on Magnetic Resonance Image (MRI) scan extending from T12 to L2. At surgery, a large abscess was encountered at the conus medullaris, from which Brucella melitensis was grown on culture. She was started on streptomycin and doxycycline for 1 month, followed by rifampicin and doxycycline for 1 month. At 2-year follow-up, she had recovered only partially and continued to have impaired bladder function.

CONCLUSION

Neurobrucellosis, if not treated early, can result in severe neurological morbidity and sequelae, which may be irreversible. Hence it is important to consider the possibility of neurobrucellosis in endemic region and treat aggressively.

Group B Streptococci Colonization in Pregnant Women: Is Screening Necessary?

Objectives

Group B Streptococcus (GBS) has been recognized as the leading cause of serious neonatal infections through mother—fetal vertical transmission in the west, however, in India, its spectrum is largely under estimated. The present study was carried out to find the incidence of rectovaginal carriage of GBS in parturient women, association with risk factors in mother and to study the neonatal outcome.

Materials and methods

A one year cross-sectional prospective study was carried out in 905 parturient women admitted at a tertiary care center meeting the selection criteria over a period of one year from June 2007 to May 2008. The inclusion criteria were all pregnant women admitted to the labor room after 35 ± 1 week of gestation. Rectal and vaginal swabs were taken and cultured on selective Todd-Hewitt broth medium followed by sub culture on blood agar and confirmation by Latex agglutination test from all the women meeting the inclusion criteria. The outcomes measured were the incidence, antenatal risk factors in mother and the neonatal outcome. Analysis was done using paired ‘t’ test, chi-square test and a p-value of <0.05 was taken as statistically significant.

Results

Incidence of group B Streptococcus (GBS) was 12.15% and detection rate was increased by 4.6% with the inclusion of rectal swabs for culture. GBS carriage was significantly increased with preterm birth (OR 8.3, 95% CI,1.1- 15.5), premature rupture of membranes (OR 7.5, 95% CI, 1.1- 13.4), prolonged duration of ruptured membranes more than 10 hours (OR 21, 95% CI,15.2-34.2) and intrapartum temperature more than 38°C(OR 3.1, 95% CI, 0.43-6.66). Birth weight less than 2.5 kg and neonatal intensive care admissions were significantly more (35.45%) in infants of GBS positive women.

Conclusion

GBS colonization was more frequent in women with risk factors. GBS pick up rate was increased by the inclusion of both rectal and vaginal swabs.

Infective endocarditis due to brucella

One of the complications of brucellosis is infective endocarditis, which carries a high mortality rate if undiagnosed or misdiagnosed. We report a case of Brucella infective endocarditis, which was diagnosed serologically and by polymerase chain reaction. After Brucella specific treatment, patient showed dramatic improvement clinically, as evident by echocardiogram findings and other investigations.

Prevalence of hepatitis C infection in HIV-seropositive individuals in and around Belgaum, south India

India has high prevalence of HIV infection. As HIV and HCV share common routes of transmission, there is every chance of an HIV-infected patient also having HCV infection. We investigated the prevalence of HCV infection in HIV seropositive individuals attending a tertiary care hospital at Belgaum, south India. A total of 16,124 serum samples from suspected patients were screened for the presence of HIV antibodies and those who tested positive for HIV were screened for HCV antibodies by using enzyme-linked immunosorbent assay (ELISA). A total of 24 (3.52%) patients were found to be co-infected with HIV and HCV. Among them, 16 (66.66%) were male and 8 (33.33%) were female. This study has revealed a relatively high prevalence of HIV/ HCV co-infection in and around Belgaum which suggests preventive and control measures should be taken against the spread of such infection in this part of India.

PCR confirmation of cutaneous manifestation due to Brucella melitensis

Human brucellosis, a zoonotic disease, is endemic in the Belgaum district, Karnataka, India. A male patient presented with a generalized itchy rash. Blood was sent for venereal disease research laboratory testing. Screening was carried out for Brucella antibodies following hospital policy and diagnosis was confirmed by PCR.

Safety and efficacy of the new CryoPop® cryotherapy device for cervical dysplasia in low- and middle-income countries: study protocol for a multicenter open-label non-inferiority clinical trial with historical controls

BACKGROUND

Cervical cancer is the fourth most common cancer in the world, affecting mainly women residing in low- and middle-income countries. Progression from a pre-invasive phase to that of an invasive phase generally takes years and provides a window of opportunity to screen for and treat precancerous lesions.

METHODS

This study is being conducted at four sites in north Karnataka, India. Community sensitization activities have been organized in the study areas to create awareness among stakeholders, including elected representatives, physicians, health care workers, and potential participants. Organized community based as well as hospital-based screening is being conducted using visual inspection with acetic acid (VIA). Screen positive women are referred to respective study hospitals for colposcopy and directed biopsy. Participants with confirmed high-grade cervical dysplasia (high-grade squamous intraepithelial lesions or HSIL) who fit all other eligibility criteria will be recruited to the study and will receive cryotherapy using CryoPop®, an innovative new cryotherapy device.

DISCUSSION

There is a need to develop an inexpensive, simple, and effective cryotherapy device for use by frontline health care providers at locations where screening and timely treatment can be given, accelerating access to cervical cancer prevention services and minimizing loss to follow-up of women with precancerous lesions who need treatment.

Diagnosis and management of postlaparotomy wound infection caused by Mycobacterium fortuitum

Mycobacterium fortuitum is ubiquitous in nature and can cause a wide variety of lesions in humans with immunocompromised or antecedent chronic illness. Clinical diagnosis is difficult and relapses are seen. This is due to the fact that they are not critically investigated and are not responded to traditional antitubercular treatment and other antibiotics. Herewith, we report a case of M. fortuitum causing laparotomy port infection-causing repeated multiple abscess on the anterior abdominal wall and treated with amikacin and clarithromycin. The wound healed completely and the patient recovered after administering a combination of amikacin and clarithromycin. We conclude that strict standard operating procedures should be followed to prevent mycobacteria other than tuberculosis (MOTT) infections during and after surgical procedures. Any postoperative, chronic infection which is not responding to conventional antibiotics should be highly suspected for such MOTT infections. Antibiotic susceptibility testing should be performed so as to identify the required antibiotic combination and treated accordingly to prevent further complications and to reduce the cost of treatment.

Maternal infection and stillbirth: a review

Introduction: Maternal infections likely are an important cause of stillbirths, especially in sub-Saharan Africa and south Asia, where the burden is highest. Due to the lack of routine testing for infection, which can be complex and often expensive, the prevalence of infection during pregnancy and the association of many infections with stillbirth are not well-documented, especially in low-resource countries.Methods: Following an extensive literature review of infection and stillbirth initially published in 2010, we conducted a review of literature in the last 10 years to identify infections associated with stillbirth, focused on those in low-resource settings.Results: During the last 10 years, over 40 bacterial, viral and other pathogens have been associated with stillbirth. Newly emerging viral infections such as Denge as well as several well-established, but not yet eliminated infections such as rubella have been associated with stillbirth. Two of the maternal infections most strongly associated with stillbirth, each with about a 2-fold risk, are malaria and syphilis but others have been associated with risk in a range of studies. With a lack of routine antenatal screening, many pathogens are identified as associated with stillbirth only through case reports. Infection remains an important, yet understudied, cause of stillbirth.Conclusion: Research studies to determine definitive associations between various infections and stillbirth are important to better understand the role of infections and strategies to reduce infection-related stillbirth.Summary This review explores the association between infections and stillbirths focusing on low-income country studies published in the last 10 years. Much information about these relationships comes from case reports. Research resulting in a better understanding of the causes and strategies to reduce infection-related stillbirth is necessary.

Oral Hygiene Status, Salivary and Microbiological Parameters Among Visually Impaired and Normal-Sighted Children After Specialized Oral Health Education: An Interventional Study

Aim and objectives To assess oral hygiene status and salivary and microbiological parameters among 12 to 15-year-old visually impaired and normal-sighted children before and after oral health education (OHE). Methodology An interventional study was conducted among 25 visually impaired children (Group A) and 25 normal-sighted children (Group B) in the age range of 12 to 15 years. Simple random sampling was used to select the study participants. A questionnaire was designed to record socio-demographic data and the dietary habits of the children on pre-decided days. The oral hygiene practices and the Decayed Missing Filled Teeth (DMFT) index were recorded, and salivary physicochemical parameters for all the selected children were evaluated, followed by saliva collection for microbial analysis. After baseline assessment, the Audio-Tactile Performance technique for Group A and the animated visual performance technique for Group B children were used to impart OHE. Periodic assessments of salivary parameters were conducted at one-month and three-month intervals. Unpaired T test/Mann-Whitney U test, repeated measures analysis of variance (ANOVA)/Friedman test, followed by Bonferroni's post hoc test were carried out to determine the difference between and within groups, respectively. All statistical tests were performed at a significance level of 5%. Results Group A demonstrated a greater change in salivary pH (6.20 ± 0.41 to 6.96 ± 0.20), salivary buffering capacity (5.80 ± 0.82 to 7.20 ± 0.65), and Streptococcus mutans count (9.36 ± 0.41 to 8.7 ± 0.45 x 104 CFU/mL) when compared to Group B. Group B demonstrated a greater Lactobacillus acidophilus count reduction (7.96 ± 0.66 to 7.50 ± 0.64 x 104 CFU/mL) when compared to Group A. Conclusion The appropriate use of specialized OHE holds particular significance in the improvement of oral hygiene status and salivary parameters, along with a reduction in the bacterial count in both visually impaired children and normal-sighted children.

Detection of extra-cellular enzymes of anaerobic gram-negative bacteria from clinically diseased and healthy sites

Anaerobic gram-negative bacteria (AGNB) produce enzymes that play a significant role in the development of disease. We tested 50 AGNB isolates, 25 each from clinically diseased and healthy human sites for in vitro production of caseinase, collagenase, etc. Majority of the isolates were Bacteroides fragilis and Porphyromonas gingivalis, which more commonly produced collagenase and haemolysin. Comparatively larger number of clinical AGNB produced collagenase (P = 0.004). No such difference was observed with other enzymes. Hence, collagenase is probably one of the key virulence markers of pathogenic AGNB, and the inhibitors targeting collagenases might help in the therapy of anaerobic infections.
