Self-perceived anxiety symptoms in school students with borderline intellectual functioning: A cross-sectional questionnaire-based study in Mumbai, Maharashtra, India

Background and Objectives

Students with borderline intellectual functioning ("slow learners") underperform in all school subjects. The primary objective of this study was to evaluate the self-perceived anxiety symptoms of slow learners. Its secondary objective was to analyze impact of sociodemographic variables on their symptoms.

Settings and Design

Cross-sectional single-arm questionnaire-based study was conducted in the learning disability clinic of a public medical college in Mumbai.

Subjects and Methods

One hundred slow learners aged ≥8 to <18 years were recruited by non-probability sampling. Their anxiety symptoms scores were measured using the Screen for Child Anxiety Related Disorders-Child version (SCARED-C) instrument.

Statistical Analysis

Multivariate regression analysis was performed for determining the "independent" impact that variables had on the SCARED-C ("individual subscales" and "overall") scores.

Results

Symptoms of "separation anxiety" were present in 40%, followed by "social anxiety" in 32%, "generalized anxiety" in 31%, "panic" in 26%, "significant school avoidance" in 24%; and "overall anxiety" in 38% of slow learners. Multivariate analysis revealed that: (i) co-occurring attention-deficit/hyperactivity disorder was significantly associated with having panic symptoms (P = 0.040), and, (ii) studying in a Secondary School Certificate or Higher Secondary Certificate educational board-affiliated school was significantly associated with having symptoms of "generalized anxiety," "social anxiety," and "overall anxiety" (P = 0.009, P = 0.026, and P = 0.046, respectively).

Conclusions

Many slow learners in our city have symptoms of anxiety disorders and overall anxiety. There is an urgent need to screen them for anxiety disorders to facilitate their optimum rehabilitation.

Prevalence of unreported atrial fibrillation in electrocardiograms with ventricular-paced rhythm: a multicenter experience

Introduction

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and a major preventable cause of stroke. The diagnosis of AF on electrocardiogram is through the recognition of absent p waves and an irregularly irregular ventricular rhythm. However, in ventricular-paced patients, the rhythm on electrocardiogram (ECG) is often regular and may obscure AF diagnosis. Thus, unrecognized AF on ECG poses a potential risk among untreated ventricular-paced patients. There is scant published data reporting the prevalence of underrecognized and untreated ECG-detected AF among ventricular-paced patients.

Objectives

In the first part of this study, we aim (1) to determine the prevalence of AF and unreported AF on ECGs with ventricular-paced rhythm obtained across all 6 hospitals in our city, Canada. Using data obtained from (1), we then aim (2) to report the rates of untreated and unreported ECG-detected AF among ventricular-paced patients with an indication for anticoagulation, (3) to describe the length of delay in AF recognition and treatment among patients who should be considered for anticoagulation at the time of ECG-detected AF and (4) to identify possible strategies that can improve reporting of AF on ECGs with ventricular-paced rhythm using our institutional ECG software.

Methods

This is a retrospective multicenter review of ventricular-paced ECGs interpreted and reported by physicians using our institutional ECG software. ECGs were reviewed and confirmed by two independent cardiologists who were blinded from the reported interpretation of the ECGs.

Results

Of the sample of 1500 ECGs with ventricular-paced rhythm from 2017–2019, 2 independent cardiologists agreed that AF was present in 622 ECGs (41.5%). Of these, 251 (40.4%) were not reported to have AF by the interpreting physician.

Conclusions

Our study shows that there is a high prevalence of unreported AF on ECG in patients with ventricular-paced rhythm in our local hospitals. Further studies are warranted on describing whether this impacts treatment and outcomes among ventricular-paced patients. This study also highlights the importance of identifying possible strategies to improve reporting of AF on ECGs with ventricular-paced rhythm.

Importance of ventilation and occupancy to Mycobacterium tuberculosis transmission rates in congregate settings

BACKGROUND

Ventilation rates are a key determinant of the transmission rate of Mycobacterium tuberculosis and other airborne infections. Targeting infection prevention and control (IPC) interventions at locations where ventilation rates are low and occupancy high could be a highly effective intervention strategy. Despite this, few data are available on ventilation rates and occupancy in congregate locations in high tuberculosis burden settings.

METHODS

We collected carbon dioxide concentration and occupancy data in congregate locations and public transport on 88 occasions, in Cape Town, South Africa. For each location, we estimated ventilation rates and the relative rate of infection, accounting for ventilation rates and occupancy.

RESULTS

We show that the estimated potential transmission rate in congregate settings and public transport varies greatly between different settings. Overall, in the community we studied, estimated infection risk was higher in minibus taxis and trains than in salons, bars, and shops. Despite good levels of ventilation, infection risk could be high in the clinic due to high occupancy levels.

CONCLUSION

Public transport in particular may be promising targets for infection prevention and control interventions in this setting, both to reduce Mtb transmission, but also to reduce the transmission of other airborne pathogens such as measles and SARS-CoV-2.

Novel interferon-gamma assays for diagnosing tuberculosis in young children in India

SETTING

The tuberculin skin test (TST) and interferon-gamma release assays (IGRAs) are used as supportive evidence to diagnose active tuberculosis (TB). Novel IGRAs could improve diagnosis, but data are lacking in young children.

DESIGN

Children (age 5 years) with suspected TB were prospectively screened at a tertiary hospital in Pune, India; the children underwent TST, and standard (early secretory antigenic target 6 and culture filtrate protein 10) and enhanced (five additional novel antigens) enzyme-linked immunospot (ELISpot) assays.

RESULTS

Of 313 children (median age 30 months) enrolled, 92% had received bacille Calmette-Guérin vaccination, 53% were malnourished and 9% were coinfected with the human immunodeficiency virus (HIV); 48 (15%) had TB, 128 (41%) did not, and TB could not be ruled out in 137 (44%). The sensitivity of enhanced (45%) and standard (42%) ELISpot assays for diagnosing TB was better than that of TST (20%) (P  0.03); however, enhanced ELISpot was not more sensitive than the standard ELISpot assay (P = 0.50). The specificity of enhanced ELISpot, standard ELISpot and TST was respectively 82% (95%CI 74-89), 88% (95%CI 81-94) and 98% (95%CI 93-100). Rv3879c and Rv3615c, previously reported to be promising antigens, failed to improve the diagnostic performance of the ELISpot assay.

CONCLUSION

The TST and the standard and novel ELISpot assays performed poorly in diagnosing active TB among young children in India.

Small Joint Fusion of the Hand – A Technique Using Coughlin Cup and Cone Reamers

We describe a method of cup and cone arthrodesis using Coughlin concave and convex reamers, which we have used in a series of 22 hand joints in 19 patients. These reamers, originally designed for use in the foot, can be used in the hand to give very accurate preparation of bone surfaces. This results in maximum bone contact and the ability to fuse the joint in any desired position. The procedure is simple, rapid and forgiving. Union was achieved in all 22 cases, usually within 3 months.

Entomophthoramycosis: a neglected tropical mycosis

The term 'entomophthoramycosis' classically refers to infections caused by members of the order Entomophthorales. A new subphylum, Entomophthoramycota, has been created to include Basidiobolomycetes, Neozygitomycetes and Entomophthoramycetes. Basidiobolomycetes encompass Basidiobolus spp., while the Entomophthoramycetes include Conidiobolus spp. Conidiobolus spp. characteristically cause rhinofacial entomophthoramycosis in apparently immunocompetent hosts. Conidiobolus spp. may also cause disseminated infection in immunocompromised patients. Basidiobolus spp. more typically cause subcutaneous entomophthoramycosis of the limbs, buttocks, back and thorax in immunocompetent patients. While once considered to be rare, there is an increasing number of reported cases of gastrointestinal infection caused by Basidiobolus spp. worldwide in countries such as United States, Thailand, Australia, Iran, Egypt and Saudi Arabia. These cases have clinical presentations similar to those of inflammatory bowel diseases, particularly Crohn's disease. Retroperitoneal, pulmonary, nasal and disseminated basidiobolomycosis have also been reported. Histology of entomophthoramycosis may reveal the Splendore-Hoeppli phenomenon. Culture of infected tissue remains the definitive method of laboratory diagnosis. However, molecular methods with specific DNA probes and panfungal primers, as well as real time PCR, are increasingly used to detect and identify these organisms in tissue. Treatment largely consists of therapy with antifungal triazoles. Surgery plays a selective role in the management of entomophthoramycosis, depending upon location, organism and extent of the infection.

New enterant in the class of uropathogens-Shewanella algae

A 70 year old diabetic male presented with fever, urgency of micturition, oliguria, swelling over both legs. His midstream urine sample was sent for microbiological examination and it revealed Shewanella algae. Patient was treated with antibiotics and he recovered completely after treatment.DOI: http://dx.doi.org/10.3126/ajms.v6i4.11503 Asian Journal of Medical Sciences Vol.6(4) 2015 92-95

Outcome of limited forefoot amputation with primary closure in patients with diabetes

Limited forefoot amputation in diabetic patients with osteomyelitis is frequently required. We retrospectively reviewed diabetic patients with osteomyelitis, an unhealed ulcer and blood pressure in the toe of > 45 mmHg who underwent limited amputation of the foot with primary wound closure. Between 2006 and 2012, 74 consecutive patients with a mean age of 67 years (29 to 93), and a median follow-up of 31 months, were included. All the wounds healed primarily at a median of 37 days (13 to 210; mean 48). At a median of 6 months (1.5 to 18; mean 353 days), 23 patients (31%) suffered a further ulceration. Of these, 12 patients (16% of the total) required a further amputation.

We conclude that primary wound closure following limited amputation of the foot in patients with diabetes is a safe and effective technique when associated with appropriate antibiotic treatment.

Protective hypothermia: An old therapy with a new prospective

Therapeutic hypothermia (protective hypothermia) has been known to have beneficial effects since ancient times but interest was renewed after two land mark publication a decade ago. The survival as well as quality of life of post cardiac arrest patients depends on neurological outcome. Mild induced hypothermia is recommended for improving the neurological status of these patients. All acute care physician, nurses and emergency medical services personals should be aware of this approach. We report a case of post cardiac arrest that displayed improved neurological status with mild therapeutic hypothermia. Case: A young, female patient experienced perioperative cardiac arrest. Immediate resuscitation lead to return of spontaneous circulation in six minutes. Her post resuscitation Glasgow Coma score (GCS) was five. We induced therapeutic hypothermia—the patient required sedation and a chemical muscle relaxant. After 24 h we began slow rewarming. On day four, her GCS improved to 14, and she was extubated on day 6. She had mild cognitive disorder but was functionally independent. She was transferred to the ward on day 11 and subsequently discharged home. Conclusion: Mild induced therapeutic hypothermia improves neurological status of post cardiac arrest patients; however, it had adverse effect of increased risk for infection, arrhythmia and electrolyte disorders.

Heparin-induced Thrombocytopenia: A known rare complication of heparin therapy

Heparin-induced thrombocytopenia (HIT) is a rare clinico-pathological abnormality. It is characterized by the development of thrombocytopenia, resulting from heparin administration, which leads to a decrease in platelet count by 50%, or to less than 1 0 0 x 1 0 3 M within 5 to 14 days. HIT causes increased morbidity and mortality, thus it is of vital importance that acute care physicians, surgeons and intensivist should be aware of this clinical entity. We report a case of heparin-induced thrombocytopenia and review of its management, including alternatives to heparin therapy.

Cefazolin and Coagulation Disorder: A case report and review of literature

A 63-year old Yemeni male, known case of endstage renal disease (ESRD), hypertension and diabetes mellitus, underwent craniotomy and endoscopic removal of an intraventricular mass. Peri-operatively he was started on cefazolin, a normal diet and regular hemodialysis without heparin. The international normalising ratio (INR) increased rapidly, reaching 4.2 on day five but responded equally rapidly to parenteral Vitamin K and withdrawal of cefazolin. Cefazolin is an antibiotic commonly used in clinical practice because of its long half-life, narrow spectrum and its ability for dose adjustment in renal failure patients. We review the literature, discuss the risk factors of its use and suggest possible mechanisms causing the prolonged coagulation.

HELLP Needs Aggressive Help

HELLP (Hemolysis Elevated Liver Enzymes and Low Platelets) syndrome is a multi-system pregnancy associated disorder, commonly seen in patients with pre-eclampsia but can occur alone. It is significantly associated with maternal-fetal morbidity and mortality.

A triad of hemolysis elevated liver enzymes and thrombocytopenia after 24 weeks of gestation is diagnostic of this syndrome. HELLP syndrome is classified depending on simple parameters but it dictates severity of the disease. Frequently encountered complications with HELLP syndrome are hemorrhagic stroke, disseminated intravascular coagulation, pulmonary edema, acute renal failure and hepatic rapture. The aggressive supportive care of failing organs with high dose of steroids will decrease the duration of HELLP syndrome, decreases intensive care and hospital stay of these patients as well as reduction in fetal complications. HELLP syndrome is associated with significant increase in morbidity and mortality of pregnant patients; hence it is of vital importance that not only obstetrician, but acute care physicians and intensivist should be aware of this clinical entity. We report a case of Classl, normotensive postpartum HELLP syndrome complicated by pulmonary edema and acute renal failure, successfully managed in our intensive care unit.

Blind Nasogastric Tube Insertion: Be careful

Nasogastric tubes are used in all specialties of medical practice. In critically ill patients, these feeding tubes provide enteral nutrition, which maintains enteric mucosal integrity as well as the immune system of the body, less risk of sepsis and decrease in length of intensive care stay. The insertion of nasogastric tube (NGT) is being considered as a simple blind bedside procedure but this procedure is not free of complications and can be fatal as these tubes can be malpositioned into the respiratory tract or central nervous system. Critically ill patients with endotracheal and tracheostomy tube are at particular risk for malpositioning of the nasogastric tubes due to loss of protective reflexes. Here we report three cases, two intubated and one patient with tracheostomy, in whom the enteral feeding tube was malpositioned into the respiratory system, detected early and a new one inserted in correct position, confirmed by x-ray. The aim of this report is to increase awareness about malpositioning of gastric feeding tubes, proper confirmation of their positioning, risk factors for malpositioning and its prevention.

Critical Care of Gynecological and Obstetric Patients: A decade of surgical intensive care experience

Despite the emergence of therapeutic advances, the morbidity and mortality still occur in the obstetric patients, although intensive care utilization by obstetric and gynecological patient, are still rare compared to the general population. Majority of obstetric patients needed the intensive care therapy compared to gynecological patients. The aim of our study was to know the indications for the intensive care admission by obstetric and gynecological patients, length of stay and outcome of these patients.

Methods: We retrospectively reviewed the medical records of all obstetric and gynecological patients admitted to our Surgical and Trauma Intensive Care Units (SICU and TICU) from February 1995 to March 2005. Indication for admission, nationality, age, and length of stay in ICU, severity of disease and outcome of these patients were recorded. Data analyzed with SPSS program.

Results: A total of 182 patients were admitted to the SICU of the Hamad Medical Corporation in Doha, Qatar, from the Women's Hospital. 159 (87%) patients were obstetric patients and 23 (13%) patients gynecological patients, 126 (69.6%) patients were admitted post Lower Segment Caesarean Section (LSCS). The most common indication for admission was 73 (39.3%) patients obstetric hemorrhage and Disseminated Intravascular Coagulation (DIC), and then 44 (25.3%) patients of hypertensive disorder of pregnancy. The major anesthesia related indication was scoline apnea, 21 (11.6%). Total three obstetric patients died, two due to severe sepsis and multi-organ failure and one due to cerebral sinus thrombosis, giving mortality rate of 1.66%.

Conclusion: Intensive care therapy required by gynecological and obstetric patient is less than the general population. The commonest indication for admission was obstetric hemorrhage, DIC, and hypertensive disorders of pregnancy. The mortality was due to septic shock with multi-organ failure, and cerebral venous sinus thrombosis.

Post-operative Fat Embolism Syndrome: A case report and review of literature

Fat embolism occurs in all patients with long bone fractures and intra-medullary reaming of long bone but is usually asymptomatic. A few patients will have pulmonary, cerebral and dermal dysfunction; this triad is called fat embolism syndrome (FES). We report a case of FES developed after intramedullary nailing of both femurs that was successfully managed in our surgical intensive care unit (SICU).

Second toe proximal phalanx interposition bone graft to correct a failed Keller's arthroplasty. A new technique

We present a case report of a novel salvage technique for a failed Keller's arthroplasty using nonvascularised phalanx transfer from the second toe to the hallux on the same foot. The technique restores length, function and relieves pain.

Necrotizing fasciitis and its association with Diabetes Mellitus

To analyze the different presentation, types of infection, predisposing factors (particularly diabetes mellitus) of necrotizing fasciitis; a rare potentially fatal rapidly progressing necrotizing infection of subcutaneous tissue and superficialfascia with secondary necrosis of overlying skin, the medical records were reviewed retrospectively of 94 patients (71 male; 23 female) admitted to the surgical intensive care unit of Hamad General Hospital, Qatar, between January 1995 and February 2005. Fifty-three patients (56.4%) were diabetic with a mean age of 55 years compared with 40.2 years in non-diabetic patients. Type 1 necrotizing fasciitis, especially of the perineal and genital regions, was more common in diabetic patients whereas type 2 necrotizing fasciitis, especially of torso and upper limbs, was more common in non-diabetic patients. Overall 63.4% of cases were type 2 necrotizing fasciitis. E.coli was the most common bacterium isolated from necrotic tissue of diabetic patients and streptococci were the most common cause of necrotizing fasciitis in non-diabetic patients. Fifteen (16%) patients died but there was no significant difference in mortality between the groups, eight (15.1%) diabetic, seven (17.1%) non-diabetic, although diabetic patients were significantly older.

Peripartum Cardiomyopathy: Report of two cases and review of literature

Peripartum cardiomyopathy (PPCM) is a rare condition affecting women in late pregnancy or up to five months of the postpartum period. The signs, symptoms and treatment of PPCM are similar to that of heart failure. Early diagnosis and proper management are the cornerstones for a better outcome for these patients. We report two cases of peripartum cardiomyopathy which were treated in the surgical intensive care unit (SICU) of Hamad General Hospital, Qatar.

An electrocardiographic algorithm for the prediction of the culprit lesion site in acute anterior myocardial infarction

BACKGROUND

Although the 12-lead electrocardiogram (ECG) has been found useful in identifying the left anterior descending (LAD) coronary artery as the infarct-related artery in acute myocardial infarction (MI), it has traditionally been felt to be incapable of localizing the culprit lesion within the LAD itself. Such a capability would be important, because anterior MI due to proximal LAD lesions carry a much worse prognosis than those due to more distal or branch vessel lesions.

HYPOTHESIS

This study investigated whether certain ECG variables--especially an ST-segment injury pattern in leads aVL and/or V1--would correlate with culprit lesion site, and an ECG algorithm was developed to predict culprit lesion site.

METHODS

The initial ECGs of 55 patients who had undergone cardiac catheterization after an anterior or lateral MI were reviewed to identify the leads with an ST-segment injury pattern; the corresponding catheterization films were then reviewed to identify the location of the culprit lesion; and these separate findings were then compared.

RESULTS

The sensitivity and specificity of an ST-injury pattern in aVL in predicting a culprit lesion before the first diagonal branch were 91 and 90%, respectively; the same values in predicting a lesion prior to the first septal branch were 85 and 78%. ST-segment elevation in V1, on the other hand, was a much less sensitive and specific predictor of a preseptal lesion. Overall, our algorithm correctly identified the culprit lesion location in 82% of our patients.

CONCLUSION

Based on our findings, we conclude that a ST-segment injury pattern in aVL during an anterior myocardial infarction predominantly reflects a proximal LAD lesion and therefore constitutes a high-risk finding.

Regional Necrotizing Fasciitis and its Outcome

Necrotizing fasciitis, a devastating progressive destructive infection of subcutaneous tissue and fascia, is a surgical emergency with a high mortality and morbidity. To analyze the location of necrotizing fasciitis, mode of presentation, microbiological characteristics, comorbid conditions, morbidty and mortality, records were reviewed retrospectively of all ninety-five patients admitted with necrotizing fasciitis to the surgical intensive care unit of Hamad General Hospital between January 1995 and February 2005. Fifteen patients died (15.1%). All patients had leucocytosis and fever on admission with a mean SOFA score varying from 8 to 10.3 according to the type of necrotizing fasciitis involved (Type 1 or 2) and the regions affected. All received aggressive fluid replacement therapy and all underwent debridement at least twice. The most common comorbid condition was Diabetes mellitus. Type 1 necrotizing fasciitis was common in gluteal, cervical and perineal regions; Type 2 was common in chest, axilla, leg and foot regions. Necrotizing fasciitis of the chest, axilla and gluteal regions had the highest mortality while necrotizing fasciitis of the perineum and genitalia had the lowest mortality.

Critical Illness Polyneuropathy in an Obstetric Patient: A case report and review

Recently it has been found that many critically ill patients develop secondary neuromuscular disorders following admission to intensive care units (ICU). One of these is critical illness polyneuropathy (CIP), a widespread symmetrical disorder affecting the peripheral nervous system and often associated with sepsis and multi-organ dysfunction. Two percent of all intensive care patients and as many as 80% of septic patients develop critical illness polyneuropathy which leads to a considerably increased risk of in-hospital mortality. The exact etiology of the condition is not known but various risk factors, differential diagnosis, treatment, management and prognosis are discussed in this report of ci woman who, following caesarian section, developed CIP, septic shock, multi-organ failure and subsequently died.

Acute Pancreatic Nine Years of Surgical ICU Experience

Acute pancreatitis has a variety of presentations from self-limiting abdominal pain to development of local and systemic complications resulting in sepsis, multi-organ dysfunction, extended intensive care stay and death. Very good quality of life in survivors justifies an optimal therapy in an intensive care setup. The records of 91 patients with acute pancreatitis were reviewed retrospectively. There was a significant difference (p < 0.001) between those with edematous pancreatitis and those with necrotic pancreati-tis as regards the length of ICU stay and severity scores: Ranson and SOFA (Sepsis-related Organ Failure Assess-ment). The most common cause of pancreatitis was biliary (70.3%) followed by hyperlipidemia (12.1%), post ERCP (5.5%), trauma (4.4%), idiopathic (6.6%) and in one case, ascariasis. Common associated diseases were hypertension (33%) and diabetes mellitus (25.3%). Six patients with necrotic pancreatitis died. It is concluded that acute pancreatitis treated in an in-tensive care unit has a favorable outcome and that a com-bination of Ranson and SOFA scores with CT index helps in establishing the prognosis.

Detection of recurrent breast cancer after TRAM flap reconstruction

Breast cancer remains a significant cause of morbidity and mortality among women today. The transverse rectus abdominis myocutaneous (TRAM) flap has played a substantial role in the reconstruction of defects secondary to mastectomy. Although such reconstruction has not been shown to adversely affect survival or local recurrence, specific screening modalities for recurrence in this population of patients have not been delineated. Three patients were examined retrospectively at the authors' institution. They presented with local recurrences of breast cancer after mastectomy and TRAM flap reconstruction. All patients' recurrences were detected on physical examination, and all had the diagnosis of recurrent carcinoma made on biopsy of the mass. A review of the literature demonstrates that mammography, ultrasound, magnetic resonance imaging (MRI), computed tomography (CT), scintimammography, and biopsy have all been used as adjuncts to clinical examination in detecting recurrence. Subsequent treatment of recurrent breast cancer is determined by the results of a metastatic workup and the receptor status of the tumor. The most reliable form of diagnosis of recurrent breast cancer after TRAM flap reconstruction remains fine-needle, core, or open biopsy if indicated.

Cloning and characterisation of ITGAV, the genomic sequence for human cell adhesion protein (vitronectin) receptor alpha subunit, CD51

The integrin family of receptors serves as major receptors for extracellular matrix-mediated cell adhesion and migration, cytoskeletal organisation, cell proliferation, survival, and differentiation. The alpha-V integrins consist of a subset which share a common alpha-V subunit combined with one of five beta subunits (beta-1, 3, 5, 6, or 8). The alpha-V integrins have been implicated in a number of developmental processes, including vasculogenesis and angiogenesis, and are therapeutic targets for inhibition of angiogenesis and osteoporosis. The human cDNA for alpha-V integrin (ITGAV) consists of a 5,717-bp transcript with a coding sequence (CDS) of 3,146 bp encoding a 150-kDa mature peptide. Here we describe the gene structure of ITGAV.

Spontaneous intramural atrial hematoma presenting as a left atrial mass

We describe an unusual case of spontaneously occurring intramural atrial hematoma with no communication with either atrium. The diagnosis of left atrial mass was made from transthoracic echocardiography. Subsequent examination with transesophageal echocardiography confirmed a large mass essentially filling the whole left atrium but failed to provide an etiologic diagnosis, which was eventually made at surgery.

Growth inhibition of human breast cancer cells by herbs and phytoestrogens

Epidemiologic studies have suggested that consumption of phytoestrogen-rich foods may protect against breast cancer, and phytoestrogens such as genistein have been reported to both inhibit and stimulate the growth of some human breast cancer cells. The phytoestrogens genistein, daidzein, biochanin A, and coumestrol were tested and found to inhibit serum-stimulated growth in both T-47D and MCF-7 breast cancer cells at 10-100 microM. Extracts of several estrogenic herbs, including hops, black cohosh and vitex, inhibited growth of T-47D cells. These in vitro results suggest that certain herbs and phytoestrogens may have potential in the prevention of breast cancer.

Mast cells of the bovine trachea: staining characteristics, dispersion techniques and response to secretagogues

Sections of the lower trachea of cattle, fixed in either Carnoy's or formalin, were stained with toluidine blue, alcian blue, or alcian blue and safranin O to study the mast cell population. After toluidine blue staining, about twice as many cells in tissue fixed in Carnoy's contained dark blue granules compared with tissue fixed in formalin. In addition, for the first time in cattle, a population of cells containing red granules was identified after staining with alcian blue and safranin O. Most of these red granules were formalin sensitive. An enzymatic dispersal technique for mast cells is described that yielded 9.4+/-0.4% mast cells (percentage of nucleated cells) with a viability of 92.3+/-0.6%. Spontaneous histamine release was 3.3+/-0.8%. Dispersed mast cells were challenged with various immunological and nonimmunological secretagogues. The calcium ionophores, A23187, ionomyocin, and BrX537A, were effective in releasing up to 94% of histamine in mast cells in a dose-response relationship. Pasteurella haemolytica culture supernate caused about 10% histamine release at a dose of 0.5 mg/mL after correction for spontaneous release. The average histamine content of the mast cells was 6.6+/-1.0 pg/cell. Cytospins of dispersed cells fixed in Carnoy's and stained with alcian blue and safranin O contained mast cells with blue and red granules, and a few cells with a mixture of both granule types. Based on the effects of type of fixation, staining characteristics and histamine content, a mix of subtypes of mast cells is present in the bovine trachea. However, functionally they respond to secretagogues differently than rodent mast cells. Without an immunological secretagogue, studies to determine compounds that will be effective in blocking mast cell degranulation will be limited.

Comparative efficacy of three measles vaccines in Indian children

A Comparative study of three types of measles vaccines was undertaken among 1005 children. Of these 527 were vaccinated with the Serum Institute of India (SII) vaccine, 230 with Schwarz (SC) and 248 were vaccinated with Edmonston-Zegreb (EZ) vaccine (imported from Zegreb). Though the majority of children reacted favourably with all the three vaccines (SII: 98.43%; SC: 93.40%; EZ: 93.0%) with a rise in titre, but the percentage of seroconversion was significantly higher with the SII vaccine (p < 0.01). The Schwarz and Edmonston Zagreb vaccines showed significantly less GM titre as compared with the other age group i.e. 9-12 months (p < 0.05). With Serum Institute of India (SII) vaccine the GM titres were almost similar in the different age groups. The overall GM titre obtained with the SII vaccine was significantly higher than the SC vaccine (p > 0.001) as well as the EZ vaccine (p > 0.001). It is of interest to note that among the infants, 22.5% children had measles antibody in them before vaccination.

Preparation of Schiff base adducts of phosphatidylcholine core aldehydes and aminophospholipids, amino acids, and myoglobin

We have prepared Schiff base adducts of the core aldehydes of phosphatidylcholine and aminophospholipids, free amino acids, and myoglobin. The Schiff bases of the ethanolamine and serine glycerophospholipids were obtained by reacting sn-1-palmitoyl(stearoyl)-2-[9-oxo]nonanoyl-glycerophosphocholine (PC-Ald) with a twofold excess of the aminophospholipid in chloroform/methanol 2:1 (vol/vol) for 18 h at room temperature. The Schiff bases of the amino acids and myoglobin were obtained by reacting the aldehyde with an excess of isoleucine, valine, lysine, methyl ester lysine and myoglobin in aqueous methanol for 18 h at room temperature. Prior to isolation, the Schiff bases were reduced with sodium cyanoborohydride in methanol for 30 min at 4 degrees C. The reaction products were characterized by normal-phase high-performance liquid chromatography and on-line mass spectrometry with electrospray ionization. The amino acids and aminophospholipids yielded single adducts. A double adduct was obtained for myoglobin, which theoretically could have accepted up to 23 PC-Ald groups. The yields of the products ranged from 12 to 44% for the aminophospholipids and from 15-57% for the amino acids, while the Schiff base of the myoglobin was estimated at 5% level. The new compounds are used as reference standards for the detection of high molecular weight Schiff bases in lipid extracts of natural products.

Clinical features and outcome of patients admitted to the intensive care unit after plastic surgical procedures: implications for cost reduction and quality of care

Recent interest in cutting cost and improving utilization and delivery of perioperative services has prompted surgeons to identify patient populations that would benefit from care in an intensive care unit as opposed to intermediate or standard care. The purpose of this study was to evaluate patients admitted to the surgical intensive care unit (SICU) after major plastic/reconstructive surgical procedures in order to determine appropriate perioperative management strategies for these patients. We reviewed retrospectively the data from 2,805 consecutive admissions to the SICU between 1990 and 1996. Forty-two patients (1.5%) who had undergone major plastic/reconstructive procedures were identified. Outcomes (mortality, length of stay in the SICU and hospital, and the degree of organ dysfunction) were compared between this population, an illness severity-matched (Acute Physiology and Chronic Health Evaluation [APACHE]-II and APACHE III) population of patients recovering from vascular surgical procedures, and a similarly matched population of SICU patients who were randomly assigned to serve as a second control group. The hospital mortality of the plastic surgical patient population (9.5%) was significantly higher than the zero mortality of the random cohort (p < 0.05). A second analysis compared the SICU plastics group to a case-controlled group of patients who were admitted to the postanesthesia care unit (PACU) for at least 24 hours of perioperative monitoring. SICU patients had significantly higher APACHE II scores (10.9) when compared to PACU patients (7.2; p < 0.01). Based on severity of illness scoring and eventual mortality, patients admitted to our SICU after major reconstructive surgery were selected appropriately for that setting. In contrast, the patients who stayed in the PACU for perioperative monitoring did not require life-supporting therapy and, therefore, were overmonitored. Care could be provided in a specialized unit with dedicated nursing specifically trained for that purpose.

Mast cell Fc epsilonRI expression in the rat intestinal mucosa and tongue is enhanced during Nippostrongylus brasiliensis infection and can be up-regulated by in vivo administration of IgE

The activation of rodent and human mast cells can occur through the cross-linking of tetrameric IgE receptors each containing single alpha- and beta- and two gamma-subunits. However, the factors that regulate the in vivo expression of Fc epsilonRI are poorly understood. We have examined the expression of the Fc epsilonRI beta-subunit in the Nippostrongylus brasiliensis (Nb)-induced mode l of rat intestinal inflammation. We developed a double-staining technique for mast cell granules (Alcian blue) and the beta-subunit of Fc epsilonRI. The intensity of immunohistochemical staining per mast cell was quantified using an image analysis system. Jejunal and tongue mast cells of Lewis rats were visible by Alcian blue staining before Nb infection, but they expressed very low levels of beta-subunit as assessed by immunohistochemical staining. These levels were increased by day 11 postinfection and reached a maximum at day 14. Since serum IgE levels correlated well with the degree of beta-subunit expression, we investigated whether the observed enhancement of receptor expression might occur through the stabilization of receptor complexes by IgE. Therefore, Lewis rats were treated with myeloma IgE, and beta-subunit expression was examined. In both tongue and jejunal tissue, a significant rise in beta-subunit expression was observed in response to IgE injection, although levels of beta-subunit expression were not as high as those observed in Nb-infected animals. The increase in beta-subunit expression was accompanied by an increase in the amount of mast cell-associated IgE. These observations may have important implications for the regulation of IgE receptor expression during disease.
