RESUMEN
Objectives: This study aimed to detect heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) among methicillin-resistant S. aureus (MRSA) isolated from healthcare-associated infections and identify staphylococcal cassette chromosome mec (SCCmec) types. Methods: This study was conducted from February 2019 to March 2020 and included patients admitted in 4 tertiary care hospitals in Karnataka, India. Isolation and identification of MRSA were done using standard bacteriological methods. Antimicrobial susceptibility testing was done using Kirby-Bauer disc diffusion; macrolide-lincosamide-streptogramin B phenotypes were identified using the D test. The minimum inhibitory concentration (MIC) of vancomycin was determined using agar dilution. hVISA were confirmed by the modified population analysis profile-area under the curve test. SCCmec types and the Panton-Valentine leukocidin (pvl) gene were detected using multiplex polymerase chain reaction. Results: Of 220 MRSA stains, 14 (6.4%) were hVISA. None of the MRSA isolates was vancomycin-intermediate or -resistant and all hVISA were susceptible to linezolid and teicoplanin. The macrolide-streptogramin B phenotype was present in 42.9% of hVISA; 92.9% of the hVISA strains had vancomycin MIC in the range of 1-2 µg/mL. Majority of the hVISA and vancomycin-susceptible MRSA were isolated from patients with skin and soft tissue infections. SCCmec III and IV were present in 50% and 35.7% of hVISA, respectively; 14.3% of the hVISA harboured SCCmec V. Conclusion: The prevalence rate of hVISA among MRSA was 6.4%. Therefore, MRSA strains should be tested for hVISA before starting vancomycin treatment. None of the isolates was vancomycin-intermediate or -resistant and all the hVISA strains were susceptible to linezolid and teicoplanin. The majority of the hVISA were isolated from patients with skin and soft tissue infections and harboured SCCmec III and IV.

BACKGROUND AND AIM: Mucositis, one of the vulnerabilities of chemotherapy, affects the physiological activities and therapeutic strategies of patients because it can affect the normal cell population. Etoposide is a commonly used chemotherapeutic agent for cancers such as oral, lung, and gastrointestinal. In addition to the abnormal metabolic processes in the body caused by tumorigenesis, new metabolic alterations can occur, such as oxidative stress, antioxidant imbalance, and inflammatory reactions, all of which can contribute to existing patient vulnerability. Therapeutic adjuvants can help overcome these toxic effects. Spondias pinnata is a tropical tree omnipresent in the coastal and Western Ghat section of India that is used for culinary purposes and as a local analgesic. Therefore, we aimed to study the anti-inflammatory effects of S. pinnata in an etoposide-induced mucositis rat model. MATERIALS AND METHODS: Small intestinal tissue homogenates from albino Wistar rats were used to estimate the levels of glutathione (GSH) and nitric oxide (NO), and activities of total antioxidant (TAO), myeloperoxidase (MPO) and Na+-K+ ATPase. The animals were grouped into: (1) normal control, (2) etoposide-induced mucositis (65 mg/kg bodyweight, single IP dose), (3) S. pinnata control group, and (4) etoposide followed by S. pinnata bark extract (200 mg/kg bodyweight, once in a day). Animals were sacrificed after 24, 48, 72, and 96 h and compared with that of the normal control group (n=6). Statistical analysis was performed using EZR software. RESULTS: We observed a significant decrease in the TAO and GSH levels with a marked increase in NO, MPO, and Na+-K+ ATPase activity in the mucositis group. A tendency to recover from the decreased TAO and GSH levels existed in the treated group, showing the protective effects of S. pinnata bark extract against mucositis. In addition, this extract also showed anti-inflammatory effects as reflected by the recovery in MPO levels at the end of 96 h. Maintenance of Na+-K+ ATPase activity in the treated group demonstrates the protective effects of the extract against the increased levels observed in the etoposide-induced mucositis group. CONCLUSION: This study revealed the protective effects of S. pinnata bark extract against the oxidative and inflammatory changes that occurred during the development ofmucositis. This would decrease the pathological burden during chemotherapy and prevent any hurdles in therapeutic modalities.
RESUMEN
Vitamin D, a steroid hormone is primarily known for its role in calcium and bone mineral homeostasis. Over the years, vitamin D has been implicated in various non-skeletal diseases. The extraskeletal phenomenon can be attributed to the presence of vitamin D receptors (VDRs) in almost all cells and identification of 1-α hydroxylase in extrarenal tissues. The vitamin D deficiency (VDD) pandemic was globally reported with increasing evidence and paralleled the prevalence of diabetes, obesity and cardiovascular diseases (CVDs). A dependent link was proposed between hypovitaminosis D glycemic status, insulin resistance and also the other major factors associated with type 2 diabetes leading to CVDs. Insulin resistance plays a central role in both type 2 diabetes and insulin resistance syndrome. These 2 disorders are associated with distinct etiologies including hypertension, atherogenic dyslipidemia, and significant vascular abnormalities that could lead to endothelial dysfunction. Evidence from randomised clinical trials and meta-analysis, however, yielded conflicting results. This review summarizes the role of vitamin D in the regulation of glucose homeostasis with an emphasis on insulin resistance, blood pressure, dyslipidaemia, endothelial dysfunction and related cardiovascular diseases and also underline the plausible mechanisms for all the documented effects.

INTRODUCTION: The ultimate goal of physiotherapy in stroke rehabilitation is focused towards physical independence and to restore their functional ability during activities of daily living (ADLs). Motor imagery (MI) is an active process during which a specific action is reproduced within working memory without any actual movements. MI training enhances motor learning, neural reorganization and cortical activation in stroke. The efficacy of MI training involving lower extremity mobility tasks need to be assessed. AIM: To evaluate the effects of combining motor imagery with physical practice in paretic Lower Extremity Muscles Strength and Gait Performance in Ambulant Stroke subjects. MATERIALS AND METHODS: A Randomized Clinical Trial was conducted in Department of Physical Therapy, Tertiary Care Hospitals, Mangalore, India which includes 40 hemi paretic subjects (>3 months post-stroke) who were ambulant with good imagery ability in both KVIQ-20 ≥ 60 and Time dependent MI screening test were recruited and randomly allocated into task-oriented training group (n=20) and task-oriented training group plus MI group (n=20). Subjects in both groups underwent task orientated training for lower extremity 45-60 minutes, 4 days per week for 3 weeks. In addition, the experimental group received 30 minutes of audio-based lower extremity mobility tasks for MI practice. Isometric muscle strength of Hip, Knee and Ankle using a hand-held dynamometer and self-selected 10 m gait speed were assessed before and after 3 weeks of intervention. RESULTS: Both the groups had found a significant change for all the outcome measures following 3 weeks of interventions with p <.05. The experimental group had shown a significant improvement in paretic hip muscles (both flexors and extensors), knee extensors and ankle dorsiflexors and gait speed compare to control group with p < .05 between group analyses. CONCLUSION: Additional task specific MI training improves paretic muscle strength and gait performance in ambulant stroke patients.
RESUMEN
OBJECTIVES: Healthcare-associated methicillin-resistant Staphylococcus aureus (MRSA) is a common pathogen worldwide and its multidrug resistance is a major concern. This study aimed to determine the clinical characteristics and antibiotic susceptibility profile of healthcare-associated MRSA with emphasis on resistance to macrolide-lincosamide-streptogramin B (MLSB) phenotypes and vancomycin. METHODS: This cross-sectional study was carried out between February 2014 and February 2015 across four tertiary care hospitals in Mangalore, South India. Healthcare-associated infections among 291 inpatients at these hospitals were identified according to the Centers for Disease Control and Prevention guidelines. Clinical specimens were collected based on infection type. S. aureus and MRSA isolates were identified and antibiotic susceptibility tests performed using the Kirby-Bauer disk diffusion method. The minimum inhibitory concentration of vancomycin was determined using the Agar dilution method and inducible clindamycin resistance was detected with a double-disk diffusion test (D-test). RESULTS: Out of 291 healthcare-associated S. aureus cases, 88 were MRSA (30.2%). Of these, 54.6% were skin and soft tissue infections. All of the isolates were susceptible to teicoplanin and linezolid. Four MRSA isolates exhibited intermediate resistance to vancomycin (4.6%). Of the MRSA strains, 10 (11.4%) were constitutive MLSB phenotypes, 31 (35.2%) were inducible MLSB phenotypes and 14 (15.9%) were macrolide-streptogramin B phenotypes. CONCLUSION: Healthcare-associated MRSA multidrug resistance was alarmingly high. In routine antibiotic susceptibility testing, a D-test should always be performed if an isolate is resistant to erythromycin but susceptible to clindamycin. Determination of the minimum inhibitory concentration of vancomycin is necessary when treating patients with MRSA infections.
RESUMEN
Gastric lavage is a routine procedure done in many cases of poisoning and it has been advocated by many as a lifesaving procedure. There may be some instances, where it might be unnecessary, ineffective or even detrimental to life. A 35 year old man walked into a casualty, 2 hours after having ingested 15 benzodiazepine tablets. Lavage was done by an unqualified person using Ewald's tube, leading to iatrogenic perforation. The unwarranted use of the procedure proved to be fatal.

Community-acquired methicillin resistant Staphylococcus aureus (MRSA) usually causes skin and soft tissue infections. However, community-acquired methicillin resistant S.aureus has been identified as a causative agent of many invasive infections like necrotizing fasciitis, pneumonia and bacteremia. Risk factors such as immunodeficiency and skin and soft tissue infections have been identified for acquiring bacteremia. We present four cases of bacteremia caused by community-acquired methicillin resistant S.aureus, risk factors and outcome.

Hemophagocytic lymphohistiocytosis (HLH) is a potentially fatal hyper inflammatory condition, if not recognized and treated in time. A high index of suspicion can help identify the condition early. This condition can occur in the primary or secondary form. Secondary HLH or hemophagocytic syndrome (HPS) secondary to infections is an important clinical entity especially in tropical world. In this article, we share our experience with this entity and make an attempt to explore literature about ravenous macrophages which occurs secondary to infections. It is a series of six cases of HLH secondary to infectious disease in our center in a coastal city in South India over last one year with follow up.

OBJECTIVE: To evaluate the effectiveness of mirror therapy on lower extremity motor recovery, balance and mobility in patients with acute stroke. DESIGN: A randomized, sham-controlled, assessor blinded, pilot trial. SETTING: Inpatient stroke rehabilitation unit. SUBJECTS: First time onset of stroke with mean post-stroke duration of 6.41 days, able to respond to verbal instructions, and Brunnstrom recovery stage 2 and above were enrolled. INTERVENTION: Mirror therapy group performed 30 minutes of functional synergy movements of non-paretic lower extremity, whereas control group underwent sham therapy with similar duration. In addition, both groups were administered with conventional stroke rehabilitation regime. Altogether 90 minutes therapy session per day, six days a week, for two weeks duration was administered to both groups. OUTCOME MEASURES: Lower extremity motor subscale of Fugl Meyer Assessment (FMA), Brunnel Balance Assessment (BBA) and Functional Ambulation Categories (FAC). RESULTS: Amongst the 22 patients included, equal number of patients participated in mirror group (N = 11) and control group (N = 11). Baseline variables were similar in both groups, except for Brunnstrom recovery stage. There was no statistical difference between groups, except for FAC. (FMA: P = 0.894; BBA: P = 0.358; FAC: P = 0.02). Significance was set at P < 0.05. CONCLUSION: Administration of mirror therapy early after stroke is not superior to conventional treatment in improving lower limb motor recovery and balance, except for improvement in mobility.
RESUMEN
The present work aims at preparing aqueous suspension of Solid lipid Nanoparticles containing Chitosan (CT) which is a biopolymer that exhibits a number of interesting properties which include controlled drug delivery. Carbamezapine (CBZ) is a lipophilic drug which shows it antiepileptic activity by inactivating sodium channels. The solid lipid Nanoparticles (SLN) of Chitosan-CBZ were prepared by using solvent injection method using ethanol as organic solvent. The prepared SLN formulations exhibited high encapsulation efficiency, high physical stability. The drug incorporated SLNs have demonstrated that the controlled release patterns of the drug for prolonged period. The prepared SLNs were characterized for surface morphology by SEM analysis, entrapment efficiency, zeta potential, FTIR, DSC and In-vitro diffusion studies. The hydrodynamic mean diameter and zeta potential were 168.7 ± 1.8 nm and -28.9 ± 2.0 mV for SLN-chitosan-CBZ respectively. Therefore chitosan-SLN can be good candidates to encapsulate CBZ and to increase its therapeutic efficacy in the treatment of Epilepsy.

OBJECTIVES: To study the clinico-epidemiological trends in melioidosis, an emerging disease in the western coastal region of India. METHODS: Data of 95 patients with melioidosis in the western coastal region of India were retrospectively analyzed with respect to monthly rainfall, risk factors, clinical presentations, and outcome. RESULTS: A strong linear correlation was seen between average monthly rainfall and the occurrence of cases (p=0.002). Mortality was seen only in patients with bacteremia (p<0.001). Nine (40.9%) patients with septic shock died (p<0.001). Age ≥ 40 years and diabetes mellitus were seen in 75.8% of cases, each. Pneumonia was the most common clinical presentation (32.6%), followed by musculoskeletal disease (20%), melioidotic lymphadenopathy (7.4%), and dental abscess (6.3%). Only 36.8% of patients had exposure to wet soil/surface water. CONCLUSIONS: Melioidosis is quite prevalent in the western coastal region of India, and is strongly associated with rainfall, age, and diabetes mellitus. Higher proportions of musculoskeletal, dental, and lymph node melioidosis were seen in this region as compared to endemic areas. Bacteremic melioidosis has a poorer prognosis than non-bacteremic melioidosis. The presence of septic shock is a strong predictor of mortality. Percutaneous inoculation may not be the main portal of entry for Burkholderia pseudomallei in this region.

INTRODUCTION: 24-hour ambulatory blood pressure (BP) monitoring is a well-validated tool that can reveal the patient's nocturnal dipping pattern. However, to the best of our knowledge, the role of home BP monitoring in identifying nocturnal dipping has not been studied. METHODS: We evaluated the nocturnal BP of 30 treatment-naive subjects using a home BP monitoring device. BP measurements were taken once during the daytime and once at night (three hours after sleep) by a blinded observer. Readings were correlated with left ventricular mass index. RESULTS: Night BP measurements were significantly lower in subjects without left ventricular hypertrophy (LVH) as compared to those with LVH, while the daytime readings were not significantly different between the two. The mean dips in nocturnal systolic and diastolic BP were 1.92% ± 6.89% and -0.55% ± 14.31%, respectively, in subjects with LVH. The corresponding values were 12.96% ± 6.16% and 11.36% ± 11.90% in those without LVH. The correlation between left ventricular mass index and night BP readings was statistically significant (systolic r = 0.66, p < 0.001; diastolic r = 0.496, p < 0.005). CONCLUSION: Nocturnal BP measurement using a home BP monitoring device may be a reliable and cost-effective method for detecting early signs of end-organ involvement such as LVH in hypertensives, especially in a resource-limited setting.

Antithyroid drugs have been used for more than 50 years for the management of hyperthyroidism. Most patients tolerate treatment well but some may develop life-threatening side effects such as agranulocytosis, aplastic anemia and cholestatic hepatitis. A 45-year-old female was diagnosed with severe hyperthyroidism. Treatment with Carbimazole 30 mg/day was initiated. Within six weeks following the start of therapy, patient developed potentially life-threatening acute cholestatic hepatitis and agranulocytosis as adverse effects to carbimazole. The patient's symptoms and laboratory abnormalities resolved following withdrawal of offending drug. Agranulocytosis and cholestatic hepatitis together is an extremely rare idiosyncratic side effect of Carbimazole treatment and considered to be dose and age-related. Antithyroid drugs are deceptively easy to use, but because of the variability in the response of patients and the potentially serious side effects, all practitioners who prescribe the drugs need to have a working knowledge of their complex pharmacology.

Papillary carcinoma is the most common malignant tumor of the thyroid, especially in countries with adequate or excess iodine in diet. Many studies indicate that a sizable number of papillary cancer cases occur in a setting of chronic thyroiditis. But the tumor that arises more frequently in thyroiditis is malignant lymphoma. We report a rare association of papillary carcinoma of thyroid in an elderly lady with adult T-cell lymphoma/leukemia. Fine needle aspiration of the thyroid, neck nodes and evaluation of the bone marrow and peripheral blood helped in the diagnosis of papillary cancer coexisting with adult T-cell lymphoma/leukemia.

Brucine is the predominant alkaloid present in the bark of the tree Strychnos nux vomica and is a weaker alkaloid when compared to strychnine. However, its toxicological property is akin to strychnine. We report a rare case of brucine poisoning complicated by acute renal failure and rhabdomyolysis. A 24-year-old male presented with a history of consumption of a decoction made from the bark of the Strychnos nux vomica tree. Soon after, he developed widespread muscle spasms and convulsions, which were promptly treated. On the fifth day of admission, he developed features of rhabdomyolysis and acute renal failure. Investigations revealed elevated creatine phosphokinase levels and elevated blood urea and serum creatinine. The patient was managed with hemodialysis and recovered gradually. There are many reports of strychnine poisoning producing rhabdomyolysis and renal failure. In this case report, attention is drawn to the fact that brucine, although a weaker alkaloid, can also produce life threatening complications like rhabdomyolysis and acute renal failure.

An attempt was made to study the usefulness of activated carbon fabric (ACF) mask to prevent lead absorption. Indigenous ACF masks were provided to eight workers involved in the manufacture of batteries. Their blood lead levels were determined before and after using these masks. There was a substantial decrease in blood lead level after using the mask among those who were under treatment for high blood lead levels. Three workers who were not under treatment for lead also showed a decrease in blood lead level, after using this ACF mask, suggesting the usefulness of ACF in preventing further exposure. Such a study has not been reported anywhere in the available literature and similar such studies with more number of masks is necessary to evaluate its effectiveness.

BACKGROUND: In regions endemic for tuberculosis (TB) such as India, presumptive anti-tuberculosis treatment is often prescribed. Melioidosis, caused by Burkholderia pseudomallei, is underdiagnosed in India, due to lack of awareness and a low index of suspicion. SETTING: A tertiary care hospital in south India. OBJECTIVE: To present our analysis of a series of 22 cases of suspected TB that was later confirmed as melioidosis. DESIGN: Twenty-two patients with culture-proven melioidosis, who were initially given empirical anti-tuberculosis treatment, were retrospectively analysed regarding clinical presentation, laboratory findings and epidemiological features, with a view to determining any significant discriminatory parameter/s that would help distinguish the two diseases. RESULTS: Eight cases mimicked pulmonary TB, five tubercular arthritis, three tubercular spondylitis, two tubercular lymphadenitis, two splenic abscess, and one each mimicked tubercular pericarditis and parotid abscess. Fever was the chief presenting complaint; all had high erythrocyte sedimentation rate (ESR) values (mean 111 mm +/- 23.7 SD); 15 (68.2%) had neutrophilic leuco-cytosis, 20 (90.9%) had diabetes mellitus. Subsequent to laboratory culture reports confirming melioidosis, appropriate treatment was instituted. CONCLUSION: Fever in a diabetic patient with high ESR and neutrophilic leucocytosis should raise suspicion of melioidosis while instituting presumptive anti-tuberculosis treatment in areas where both diseases are prevalent.

Between January 2005 and December 2006, a higher incidence of paratyphoid fever (53.8%) compared to typhoid fever (44.9%) has been observed at a tertiary hospital in South India. A definite seasonal pattern of incidence is seen in paratyphoid fever (peak incidence during October-December, i.e., post monsoon period) but not in typhoid fever. Decreased fluoroquinolone susceptibility is much higher in S. Paratyphi A (98.8%) as compared to S. Typhi (46.5%). These findings are of importance in therapeutic decision making, development of vaccination strategies and implementing public health measures for disease control.
