An anthropological history of Nepal's Female Community Health Volunteer program: gender, policy, and social change

BACKGROUND

Community health workers (CHWs) are central to Primary Health Care globally. Amidst the current flourishing of work on CHWs, there often is a lack of reference to history-even in studies of programs that have been around for decades. This study examines the 35-year trajectory of Nepal's Female Community Health Volunteers (FCHVs).

METHODS

We conducted a content analysis of an archive of primary and secondary research materials, grey literature and government reports collected during 1977-2019 across several regions in Nepal. Documents were coded in MAXQDA using principles of inductive coding. As questions arose from the materials, data were triangulated with published sources.

RESULTS

Looking across four decades of the program's history illuminates that issues of gender, workload, and pay-hotly debated in the CHW literature now-have been topics of discussion for observers and FCHVs alike since the inception of the program. Following experiments with predominantly male community volunteers during the 1970s, Nepal scaled up the all-female FCHV program in the late 1980s and early 1990s, in part because of programmatic goals focused on maternal and child health. FCHVs gained legitimacy as health workers in part through participation in donor-funded vertical campaigns. FCHVs received a stable yet modest regular stipend during the early years, but since it was stopped in the 1990s, incentives have been a mix of activity-based payments and in-kind support. With increasing outmigration of men from villages and growing work responsibilities for women, the opportunity cost of health volunteering increased. FCHVs started voicing their dissatisfaction with remuneration, which gave rise to labor movements starting in the 2010s. Government officials have not comprehensively responded to demands by FCHVs for decent work, instead questioning the relevance of FCHVs in a modern, medicalized Nepali health system.

CONCLUSIONS

Across public health, an awareness of history is useful in understanding the present and avoiding past mistakes. These histories are often not well-archived, and risk getting lost. Lessons from the history of Nepal's FCHV program have much to offer present-day debates around CHW policies, particularly around gender, workload and payment.

Slurry phase biodegradation of heavy oily sludge and evidence of asphaltene biotransformation

Oily sludge management is a global environmental concern due to its hazardous nature. Oily sludge obtained from a refinery in India had 19-21% oil content. The oil was highly enriched in the asphaltene fraction. Slurry phase biodegradation of this oily sludge in presence of a 3-membered bacterial consortium was optimized in presence of Triton X-100 to increase the bioavailability of hydrocarbons. Triton X-100 at 4 times the critical micelle concentration (CMC) showed the highest degradation where oil removal of 53.1% was achieved from a 10% sludge slurry over 90 days. GCxGC analysis of n-alkanes present in the oily sludge after the biodegradation study showed an increase in the lower n-alkanes, i.e., dodecane and tridecane over the first 30 days, whereas the higher n-alkanes were removed to a much higher extent. Heptadecane showed the maximum extent of degradation with 94.9% removal in 90 days and an initial degradation rate of 0.079 day^-1. The, maximum rate of degradation was observed for pentacosane (0.083 day^-1) with 93.7% removal in 90 days. The increase in the lower n-alkanes may be attributed to biotic transformation of the asphaltene fraction which was also confirmed through FTIR and pyrolysis GCxGC analysis. Biodegradation was found to cause changes in the pyrolysis product of asphaltenes where four and three-ring pyrolysis products decreased while the one and two-ring pyrolysis products increased. In presence of the consortium asphaltene removal over 90 days was 12% whereas only 0.4% removal was obtained in the abiotic controls.

Characterization and biodegradability assessment of water-soluble fraction of oily sludge using stir bar sorptive extraction and GCxGC-TOF MS

Percolation of water through oily sludge during storage and handling of the sludge can cause soil and groundwater contamination. In this study, oily sludge from a refinery was equilibrated with water to obtain the water-soluble fraction (WSF) of oily sludge. The WSF had dissolved organic carbon (DOC) of 166 mg/L. Human cell line-based toxicity assay revealed IC₅₀ of 41 mg/L indicating its toxic nature. The predominant compounds in WSF of oily sludge included isomers of methyl, dimethyl and trimethyl quinolines and naphthalenes along with phenol derivatives and other polynuclear aromatic hydrocarbons (PAHs). Biodegradation of WSF of oily sludge was studied using a consortium of Rhodococcus ruber, Bacillus sp. and Bacillus cereus isolated from the refinery sludge. The consortium of the three strains resulted in 70% degradation over 15 days with a first-order degradation rate of 0.161 day^-1. Further analysis of the WSF was performed using the stir-bar sorptive extraction (SBSE) followed by GCxGC-TOF MS employing a PDMS Twister. The GCxGC analysis showed that Bacillus cereus was capable of degrading the quinoline, phenol and naphthalene derivatives in WSF of oily sludge at a faster rate compared to pyridine and benzoquinoline derivatives. Quinoline, phenol, biphenyl, naphthalene, pyridine and benzoquinolines derivatives in the WSF of oily sludge were reduced by 87%, 92%, 88%, 77%, 40% and 62%, respectively with respect to the controls. The WSF of oily sludge contained, n-alkanes, ranging from n-C12 to n-C18 which were removed within 2 days of biodegradation.

Knowledge of Stroke among Hypertensive Patients in Dhulikhel

Background More than 50% of patients with stroke have hypertension, a common modifiable risk factor for stroke. Studies reported that 90% of diagnosed hypertensive patients do not seek for treatment in Nepal and the reason for this remains unexplored. There is a possibility that lack of knowledge of stroke and its potential causes may be the reason. Objective To assess the knowledge of stroke in a group of patients with hypertension in suburban Nepal. Method Hypertensive patients visiting a tertiary care hospital in Nepal were approached and were included if they were 18 years or older. We used the Nepali version of 'Awareness of Stroke, Risk Factors, and Treatment' questionnaire to assess the knowledge of stroke. Descriptive statistics were used to analyze the results. Result A total of 273 patients were included with the mean age of 56 years. Almost half (48%) of the patients were uneducated. We found that only 24% of the patients identified brain as an organ affected by stroke, only 32% were aware about more than one warning signs of stroke, 64% reported that they were unaware of the treatment options for stroke and only 5% reported control of blood pressure as a part of stroke management. The commonest reported identifiable risk factor for hypertension was high blood pressure (44%). Conclusion There are significant knowledge gaps regarding stroke in hypertensive patients. Although most patients recognized hypertension as a risk factor for stroke, they were unaware of treatment options. Increasing awareness of hypertension as a risk factor for stroke may help to prevent the stroke burden in Nepal.

Patient’s perspective on early treatment retention in take home buprenorphine maintenance treatment- an explorative study from India

Introduction

Currently, Buprenorphine maintenance therapy (BMT) is an evidence-based treatment in retaining patients who are dependent on opioids. However, factors influencing retention are often measured objectively. Studies on patient’s perspectives on take home BMT in developing countries are limited.

Objectives

This study examines the potential factors influencing treatment compliance in the early phase of Buprenorphine maintenance treatment from the patient’s perspective

Methods

Participants (n=89) who were initiated on BMT were recruited and followed after six weeks. A semi-structured interview was conducted with 62 patients who remained in treatment and 24 patients who dropped out of the study

Results

Based on the semi qualitative analysis some of the factors which facilitated the patient’s retention in treatment were: (1) Effectiveness in blocking withdrawal symptoms (2) effectiveness in reducing their cravings and controlling their opioid use (3) decreased fear of withdrawal and/or missing doses(4) improvement in the quality of life(5) patient-related factors like family support (6) effectiveness of the treatment program. Around nine percent of patients reported family support as the reason for retention, which is not noticed in other studies. Barriers reported by the patients while on medication were: (1) negative effect experienced with medication (2) program related difficulties like distance, unavailability (3) major life event interrupting the treatment (4) patient-related factors like low mood, financial constraints.

Conclusions

Understanding factors associated with barriers to treatment provide insights into preventable factors that contribute to premature drop out from BMT and to improve clinical practice, policy decisions, or future research.

Comorbid depressive symptoms in persistent delusional disorder: A retrospective study from India

Background

Previous studies have reported depressive symptoms in patients with persistent delusional disorder (PDD). Patients with PDD and depression may need antidepressants for treatment.

Aim

The aim of the study was to compare the sociodemographic profile, clinical presentation and treatment response in patients with PDD with and without comorbid depressive symptoms.

Methods

We conducted a retrospective chart review of patients diagnosed with PDD (ICD-10) from 2000 to 2014 (n = 455). We divided the patients into PDD + depression (n = 187) and PDD only (n = 268) for analysis.

Results

Of the 187 patients with PDD + D, only eighteen (3.9%) were diagnosed with syndromal depression. There were no significant differences in sociodemographic profile including sex, marital and socioeconomic status (all P > 0.05). PDD + D group had a significantly younger age at onset ([PDD + D: 30.6 9.2 years vs. PDD: 33.5 11.1 years]; t = 2.9, P < 0.05). There was no significant difference between the clinical presentation including mode of onset, the main theme of their delusion and secondary delusions (all P > 0.3). However, comorbid substance dependence was significantly higher in patients with PDD only. (χ2 = 5.3, P = 0.02). In terms of treatment, response to antipsychotics was also comparable ([> 75% response: PDD + D = 77/142 vs. PDD = 106/179); χ2 = 1.9, P = 0.3). There was a significant difference between the two groups in terms of antidepressant treatment ([PDD + D = 32/187; 17% vs PDD: 17/268; 6%), χ2 = 12.9, P = 0.001).

Discussion

Patients with PDD + D had significantly earlier onset of illness. These patients may require antidepressants for treatment.

Primary Total Hip Replacement in The Military Hospital in Kathmandu

INTRODUCTION

Total hip replacement is one of the most widely performed and amongst the most successful orthopedic procedures performed worldwide. Even though it is a common orthopedic procedure in developed nations, it is performed only in selected centers in Nepal. This study will review the functional outcome of total hip replacements carried out in Shree Birendra Hospital.

METHODS

We reviewed the records of total hip replacements, which were carried out in Shree Birendra Hospital, Kathmandu. Twenty-one hips were cemented and nineteen were uncemented. Cases were followed up in six weeks, twelve weeks, six months and every year from then on. Outcome in terms of Harris hip score of 40 osteoarthritic hips were measured pre-operatively as well as post-operatively.

RESULTS

The mean age of the patients was 50.63 years (range 22-79 years). The commonest reason for the replacement was primary osteoarthritis of the hip. Thirty-nine patients underwent unilateral total hip replacement while in one patient both hips were replaced. The mean Harris hip score for the forty hips that were available at the latest follow-up examination at an average of five years (range two to six and a half years) after the operation was 85.2 ± 7.65 points as compared to the pre-operative mean Harris hip score of 32.38 ± 3.4.

CONCLUSIONS

Based on improved Harris hip scores, we believe that THR is a good option in patients with end stage arthritis of the hip.

A comparison of risperidone and olanzapine in the acute treatment of persistent delusional disorder: Data from a retrospective chart review

Introduction

There is a lack of pharmacological trials studying drug response in Persistent Delusional Disorder (PDD) to guide clinical practice. Available reviews of retrospective data indicate good response to second-generation antipsychotics, but even such data from India is sparse.

Objectives and aims

We aimed to compare the response of acute PDD to risperidone and olanzapine in our retrospective review.

Methods

We conducted a retrospective chart review of patients diagnosed with PDD (ICD-10) from 2000 to 2014 (n = 455) at our Center. We selected the data of patients prescribed either olanzapine or risperidone for the purpose of this analysis. We extracted data about dose, drug compliance and response, adverse effects, number of follow-up visits and hospitalizations. The study was approved by the Institute Ethics Committee.

Results

A total of 280/455 (61%) were prescribed risperidone and 86/455 (19%) olanzapine. The remaining (n = 89; 20%) had received other antipsychotics. The two groups were comparable in socio-demographic and clinical characteristics of PDD. Compliance was good and comparable in both groups (> 80%, P = 0.2). Response to treatment was comparable in both groups (85% partial response and > 52% good response, all P > 0.3). Olanzapine was effective at lower mean chlorpromazine equivalents than risperidone (240 vs. 391, P < 0.05).

Conclusion

Our study indicates a good response to both risperidone and olanzapine, if compliance to treatment can be ensured. In the absence of specific treatment guidelines for PDD, second-generation antipsychotics like risperidone and olanzapine offer good treatment options for this infrequently encountered and difficult to treat psychiatric disorder.

Return to preinjury status after routine knee arthroscopy in military population

BACKGROUND

Knee arthroscopy is frequently advised procedure for knee-related problems in serving soldiers. The scanty published literatures have documented wide range of recovery duration ranging from nine days to four weeks even for routine uncomplicated arthroscopy. However, neither of these studies evaluated military population, where arthroscopic procedures are frequent and physical demands are different. The aim of this study was to ascertain the time required to return to unrestricted physical activities in serving military population.

METHODS

This was a prospective descriptive study enrolling 51 patients who underwent two portal arthroscopic procedures like diagnostic arthroscopy, meniscectomy, loose body removal and excision of plica or combination of these. A uniform home based physiotherapy protocol was used for everyone. All of them were followed up at 2nd, 4th, 6th, 8th and 12th postoperative weeks. At each follow up, 2000 International Knee Documentation Committee subjective knee evaluation form was filled and submitted for analysis.

RESULTS

Although all of our patients were able to walk around without any support at two weeks follow up, 88% had restriction to activities of daily living because of knee related problems. The mean International Knee Documentation Committee score was 41 at 1st follow up, which gradually improved to 64, 86, 94, 94 at 4th, 6th, 8th and 12th week follow up respectively. At 6 weeks 91% resumed their preinjury status which reached 94% in eight weeks.

CONCLUSIONS

Most of the soldiers return to unrestricted activities within six to eight weeks after diagnostic arthroscopy, meniscectomy, loose body removal and excision of plica or combination of these procedures.

Cephalometric evaluation of mandibular advancement at different horizontal jaw positions in obstructive sleep apnoea patients: a pilot study

BACKGROUND

The aim of this study was to comparatively evaluate the efficacy of the mandibular advancement device (MAD) at 50% (P2) and 75% (P3) of maximum mandibular advancement, relative to maximum intercuspation (P1) subjectively and objectively.

METHODS

Eighteen subjects previously diagnosed with obstructive sleep apnoea (OSA) were selected for the study. ESS score, VAS score, soft palate angle, MP-H distance, S-H distance, a C4 -H distance, a Pu -p Pu distance and total pharyngeal area were calculated at P1, P2 and P3 positions with the help of an adjustable MAD. The results were statistically analysed.

RESULTS

ESS score, VAS score, soft palate angle, MP-H distance, S-H distance and radius of curvature of airway at P2 and P3 were significantly lower compared to P1, but there was no significant difference between P2 and P3.

CONCLUSIONS

The MAD produced significant improvement in objective signs and subjective symptoms at both 50% and 75% of the maximum mandibular protrusion positions at comparable comfort levels. Therefore, MAD may be given at 50% of maximum advancement in order to reduce dental or temporomandibular joint disturbances.

Calcaneal Myxoid Chondrosarcoma: A Rare Case

Skeletal myxoid chondrosarcoma is an extraordinarily rare neoplasm with a distinct histological morphology. Although it grows slowly, the clinical course was found to be worse than usual chondrosarcoma. We report a case of a Skeletal myxoid chondrosarcoma in the calcaneus of a 21-year-old female who presented to us with a feature of gradually increasing benign swelling left foot for last two years. Initial investigations were indicating towards a benign lesion for which excision of the lesion was performed. But intra operative findings were suggestive of an aggressive lesion, and to our utter surprise histopathologically it turned out to be Myxoid Chondrosarcoma. Because of its high malignant nature below knee amputation was performed as second definitive surgery. Since her clinical course and radiological pictures were suggestive of benign lesion we got carried away with a diagnosis of chondrmyxoid fibroma and excision of the lesion was attempted without attempting histopathological diagnosis by less invasive methods. Keywords: caldaneal; chondrosarcoma; myxoid.

Reduction of Acute Anterior Shoulder Dislocation Using Intraarticular Lidocaine(IAL) and Stimson’s Technique

Introduction: Shoulder dislocation is common injury requiring urgent reduction. For the reason that patient is not nill orally and anesthetists are not available, reduction under intra venous anaesthesia is not possible. This study was aimed to evaluate the effectiveness of intraarticular lidocaine and stimson’s technique of shoulder dislocation, which could be performed without anesthetist and irrespective of nill orally status. Methods: A prospective observational study was performed from December 2009 to December 2010. Under all antiseptic precautions 20 ml of Lidocaine was injected intraarticularly and reduction was performed by Stimson’s technique. Visual Analogue Score, time for reduction and failure to reduction by this technique was recorded. Results: Out of 27 dislocations 22 were successfully reduced and remaining required added scapular manipulation. The mean VAS scor was 2.3±1.26 and the mean time of reduction was 17.96±1.9 minutes. Conclusion: Stimson’s method with Intraarticular Lidocaine is effective, safe, less costly and can be performed in periphery where anesthetist and monitoring facilities are not available.

Combined Spinal Epidural Anesthesia for Total Hip Replacement Surgery in Birendra Army Hospital

Introduction: Total Hip Replacement surgery is one of the most commonly performed surgeries worldwide. Epidural anaesthesia have shown decrease incidence of DVT in these patient. Hence, combined spinal epidural spinal anesthesia is now a preferred technique over spinal anesthesia alone. We have been practicing combined spinal epidural anesthesia routienely in total joint replacement, but have not analyzed the result. The aim of this study was to analyse various aspect of combined spinal epidura anesthesia. Methods: thirteen cases of ASA I and II who underwent Total Hip Arthroplasty under combined spinal epidural anesthesia were analysed. First epidural was given in space L2-3/L3-4 and patency was confirmed with test dose with InjXylocaine 2% with Adrenaline 3 ml, followed by Spinal anesthesia one space below with Bupivacaine 0.5% 3 ml. Results: Intra operative Mean Blood Pressure had dropped up to 55 mm of Hg.To maintain Blood pressure, Intravenous Fluid was given in average is 2423.077 ml and Vasopressure drug (Mephenteramine Maleate) was given in average of14.769 mg. Dura was accidentally puncture in one patient during epidural insertion and two epidural failed to provide post operative analgesia. Post operative rehabilitation was easy, one one patient developed DVT after 4 weeks of surgery. Conclusion: Combined epidural analgesia effectively manages postoperative pain, allows early ambulation and reduces the risk of deep vein thrombosis and thromboembolism, Although significant drop of Blood pressure was noted in all cases.

Comparative study on the effect of chemicals on Alternaria blight in Indian mustard--a multi-location study in India

High severity of Altemaria blight disease is a major constraint in production of rapeseed-mustard in India. The aim of this study was to investigate the suppressive potential of chemicals viz., zinc sulphate, borax, sulphur, potash and calcium sulphate, aqueous extracts viz., Eucalyptus globosus (50 g l-1) leaf extract and garlic (Allium sativum) bulb (20 g l-1) extract, cow urine and bio-agents Trichoderma harzianum, Pseudomonas fluorescence in comparison with the recommended chemical fungicide (mancozeb), against foliar disease Alternaria blight of Indian mustard [Brassica juncea (L.) Czern. and Coss] under five different geographical locations of India. Mancozeb recorded the lowest mean severity (leaf: 33.1%; pod: 26.3%) of Alternaria blight with efficacy of garlic bulb extract alone (leaf = 34.4%; pod = 27.3%) or in combination with cow urine (leaf = 34.2%; pod = 28.6%) being statistically at par with the recommended chemical fungicide. Chemicals also proved effective in reducing Alternaria blight severity on leaves and pods of Indian mustard (leaf = 36.3-37.9%; pod = 27.5-30.1%). The effective treatments besides providing significant reduction in disease severity also enabled increase in dry seed yield of the crop (mancozeb = 2052 kg ha-1; garlic = 2006 kg ha-1; control = 1561 kg ha-1).

Barriers to care for women with substance use

Introduction

Substance use among females showing an increasing trend in India. Though there is an increase in the rate of women approaching Deaddiction centre for treatment it is lower than the community prevalence of women with substance use.

Objectives

This study aims to look at the barriers preventing women from seeking treatment.

Aim

To assess the self reported barriers to seek treatment for women with substance users.

Methodology

A total of 50 substance using women were included among 52 visiting our de-addiction centre from Oct 09 till early part of Jan 10. All of them were self rated on barrier to care questionnaire specially prepared for the study.

Results

The mean age of the sample was 42.32 (SD 12.37). Majority of them were married, house wives studied up to primary. The most common substances used were Alcohol and tobacco (36%), followed by alcohol (26%) and tobacco (26%). The common perceived barriers to care are substance use has a solution to their problem (80%), disadvantage life circumstances (70%), lack of information on treatment options (64%), limited knowledge about treatment available (64%), shame/guilt of using the substance (64%) and limited knowledge about substance use problems (62%).

Conclusion

Findings highlights the areas that require attention for women with substance use. Handling these issues in a better way may increase the treatment seeking in women substance users.

Baclofen in cannabis dependence syndrome - a open-label study and a brief follow up

Aim

To study the effect of baclofen in preventing drug use in persons with cannabis misuse.

Methodology

An open label study to asses the effect of baclofen in treating persons with cannabis dependence (ICD-10 criteria) with assessments of outcome every month for a period of three months.

Results

20 male subjects (mean age of 29.70 ± 10.19 years) with a mean age at development of dependence of 20.75 ± 09.34 years and mean duration of cannabis use of 89.40 ± 57.41 months, were treated with baclofen (mean dose of 33.75 ± 04.83 mg./day). At three months 12 subjects (60%) completely stopped, 6 subjects (30%) decreased the frequency and 2 subjects (10%) continued the same frequency of the cannabis intake.

Conclusion

Our findings provide preliminary support for the use of baclofen in maintaining abstinence and improving outcome in patients with cannabis dependence.

Adamantinoma of tibial shaft

Adamantinoma is an extremely rare primary bony neoplasm. Because of its malignant nature, accurate and early diagnosis is very important. On the other hand adamantinoma mimics many benign conditions, so it is doubly important to establish correct tissue diagnosis to avoid radical surgery with morbidities. Because of its rarity, diagnosing adamantinoma still remains difficult, even if when it occurs in classical sites. We report a case of adamantinoma of tibial shaft diaphysis in a 23 year male. In this case, because of classic clinic-radiological features, we were suspecting adamantinoma from very beginning but final diagnosis was delayed for nine months.

Abstract

Gluon-spin contribution to the proton spin from the double-helicity asymmetry in inclusive pi0 production in polarized p+p collisions at [sqrt]s=200 GeV

The double helicity asymmetry in neutral pion production for pT=1 to 12 GeV/c was measured with the PHENIX experiment to access the gluon-spin contribution, DeltaG, to the proton spin. Measured asymmetries are consistent with zero, and at a theory scale of micro2=4 GeV2 a next to leading order QCD analysis gives DeltaG[0.02,0.3]=0.2, with a constraint of -0.7<DeltaG[0.02,0.3]<0.5 at Deltachi2=9 (approximately 3sigma) for the sampled gluon momentum fraction (x) range, 0.02 to 0.3. The results are obtained using predictions for the measured asymmetries generated from four representative fits to polarized deep inelastic scattering data. We also consider the dependence of the DeltaG constraint on the choice of the theoretical scale, a dominant uncertainty in these predictions.

Neuronal classes in the corticoid complex of the telencephalon of the strawberry finch, Estrilda amandava

The present study, based on neurohistological techniques (Nissl-staining, Golgi-impregnation), focuses on the cytoarchitecture of the corticoid complex in the strawberry finch, Estrilda amandava. This complex in birds occupies the dorsolateral surface of the telencephalic pallium and remains subdivided into an intermediate corticoid area (CI) and a dorsolateral corticoid area (CDL). The CDL in the strawberry finch is a thin superficial part of the caudal pallium adjoining the medially situated hippocampal formation, whereas the CI is demarcated between the CDL and the parahippocampal area of telencephalon. Neurons of the corticoid complex are classified into three main cell groups: predominant projection neurons, local circuit neurons and stellate neurons. The spinous projection neurons send out distant projecting axons that typically extend several varicose collaterals. Most of these collaterals lie parallel to the ventricle. These neurons are subclassified into pyramidal neurons (localized only in the CI) and multipolar neurons (present in both the CI and CDL). The CDL also possesses small and medium-sized horizontal cells, which are bitufted or multipolar with smooth, moderately branching dendrites. The aspinous local circuit neurons extend short axons that ramify locally. Stellate neurons have sparse spinous dendrites and locally arborizing axons. The corticoid complex of birds corresponds to the lateral cerebral cortex of lizards and to the entorhinal cortex of mammals on the basis of neuronal morphology and bidirectional connections between adjacent areas.

Femoral neck stress fractures in military personnel

INTRODUCTION

Stress fractures are common during military training but femoral neck stress fractures are uncommon and sometimes pose diagnostic and therapeutic challenges. An incomplete stress fracture with excellent prognosis, if left unprotected, can lead to displaced femoral neck fracture with almost 63% complication rate even with best of the treatment. The aim of this study was to analyze various aspects of the femoral neck stress fracture so that early diagnosis can be made to prevent devastating complications like osteonecrosis and non-union.

METHODS

The four year army hospital record of 16 patients with femoral neck stress fracture were studied. Their demographic profile, type of fracture, presentation delay, on set of clinical symptoms and complication of femoral neck stress fracture were critically analyzed.

RESULTS

The mean age of the patient was 19.94 years. Total 74% of them developed first symptoms of stress fracture between four to seven weeks of training. There was 3.4 weeks delay from the clinical onset of symptoms to the diagnosis of stress fracture. The type of femoral neck stress fracture were compression (31.25%), tension (18.75%) and displaced (50%). Out of eight displaced type of fractures, 5 (62.5%) had developed complications (3 osteonecrosis and 2 nonunion).

CONCLUSIONS

Femoral neck stress fracture occurs in initial four to seven weeks of training. The high index of suspicion in initial period of training can help to detect and decreases significant morbidity.

Cyto-architecture and neuronal types of the dorsomedial cerebral cortex of the common Indian wall lizard, Hemidactylus flaviviridis

The cyto-architecture and morphology of the neuronal types of the dorsomedial cortex of the lizard, Hemidactylus flaviviridis has been studied with the help of Cresyl violet staining and Golgi impregnation method. The dorsomedial cerebral cortex displayed three neuronal layers. Layer-I contains only few neuronal somas and also the dendrites ascending from the subjacent layers. Layer-II is characterized by two to three cell thick densely packed neuronal somas. Layer-III contains loosely packed neuronal somas and the dendrites and axon descending from layer-I and II. Below the layer-III an ependymal layer is observed just above the ventricle. Six classes of neurons were distinguished in the cellular layer of dorsomedial cortex of Hemidactylus flaviviridis: bitufted neurons, pyramidal neurons, inverted pyramidal neurons, bipyramidal neurons, multipolar neurons, and candelabra-like monotufted neurons. The pyramidal cells were large showing more or less single type present in the cellular layer. The multipolar neurons have mostly intracortical dendritic branching and connections. Bipyramidal neurons showed pyramidal appearance of their soma and send dendritic branches towards the superficial plexiform layer and deep plexiform layer. The candelabra-like monotufted neurons have very high dendritic branching. The comparison of the neuronal types of dorsomedial cortex of reptiles with the parahippocampal area of birds and CA3 region of mammalian hippocampus suggests possibility of their homology.

Tolosa-Hunt syndrome: MRI appearances

A review of MRI findings in seven patients with Tolosa-Hunt syndrome was carried out. Seven patients presented with unilateral painful ophthalmoplegia. Magnetic resonance imaging studies were carried out to evaluate the cavernous sinuses and orbits. Coronal fast spin-echo T2-weighted images and fat-saturated T1-weighted coronal and transverse images with and without contrast enhancement were obtained for the cavernous sinuses and orbits. All patients showed focal-enhancing masses expanding the ipsilateral cavernous sinus. In one patient the mass was extending to the orbital apex and intraorbitally. All patients recovered on corticosteroid therapy and resolution of the masses was documented on follow-up MRI studies in five patients. One patient had a relapse of symptoms after discontinuing therapy. Magnetic resonance imaging studies of the cavernous sinus and orbital apex show high sensitivity for the detection and follow up of inflammatory mass lesions in Tolosa-Hunt syndrome. Magnetic resonance imaging should be the initial screening study in these patients.

Intestinal myiasis caused by Muscina stabulans

Intestinal maggots were isolated from a patient, who had reported to the Department of General Medicine of Sri Manakula Vinayagar Medical College, Puducherry, in southern India with complaints of abdominal distress, bloating of abdomen and intestinal hurry following a meal. He was diagnosed as a case of intestinal myiasis. Maggots obtained from his stool were identified to be Muscina stabulans based on characteristic patterns of posterior spiracles. He was treated with purgatives and albendazole. This intestinal myiasis case caused by M. stabulans is reported here because of its rare occurrence and the need to establish a correct diagnosis.

System size and energy dependence of jet-induced hadron pair correlation shapes in Cu+Cu and Au+Au collisions at square root sNN=200 and 62.4 GeV

We present azimuthal angle correlations of intermediate transverse momentum (1-4 GeV/c) hadrons from dijets in Cu+Cu and Au+Au collisions at square root sNN=62.4 and 200 GeV. The away-side dijet induced azimuthal correlation is broadened, non-Gaussian, and peaked away from Delta phi=pi in central and semicentral collisions in all the systems. The broadening and peak location are found to depend upon the number of participants in the collision, but not on the collision energy or beam nuclei. These results are consistent with sound or shock wave models, but pose challenges to Cherenkov gluon radiation models.

Cytoarchitectonic organization and morphology of the cells of hippocampal complex in strawberry finch, Estrilda amandava

Neurons in the hippocampal complex (dorsomedial forebrain) were described and located following Golgi impregnation. Five fields were recognized in the hippocampal complex: medial and lateral hippocampus, parahippocampal area, central field of the parahippocampal area and crescent field. In the medial hippocampus three layers have been observed: suprapyramidal towards the pial surface, pyramidal at the central and infrapyramidal adjacent to the ventricle. Neurons of the hippocampal complex were classified in to two main cell groups: predominant projection neurons with spinous dendrites and local circuit neurons. Projection neurons were further sub classified into three main types: pyramidal, pyramidal like, and multipolar neurons. In addition to these neurons, monotufted and bitufted neurons were also observed in the medial and lateral hippocampus with low frequency. The pyramidal neurons were dominant neuronal types in the pyramidal layer-II of the medial hippocampus, mixed with pyramidal like and multipolar neurons. Pyramidal and pyramidal-like neurons were found restricted in the pyramidal layer II of the medial hippocampus while the multipolar neurons were uniformly distributed in all subfields of the hippocampal complex. In the lateral hippocampus irregular shaped radial glial cells were present near the ventricular wall and projecting their dendrites towards the pia. Second group of local circuit neurons with local arborization of their projections were present in the medial hippocampus and in parahippocampal area.

Evidence for a long-range component in the pion emission source in Au+Au collisions at sqrt sNN=200 GeV

Emission source functions are extracted from correlation functions constructed from charged pions produced at midrapidity in Au+Au collisions at sqrt[s(NN)]=200 GeV. The source parameters extracted from these functions at low k(T) give first indications of a long tail for the pion emission source. The source extension cannot be explained solely by simple kinematic considerations. The possible role of a halo of secondary pions from resonance emissions is explored.

Discovery of highly potent small molecule kallikrein inhibitors

Uncontrolled kallikrein activation is involved in diseases such as hereditary angioedema, bacterial septic shock and procedures such as cardiopulmonary bypass. Here we report a series of small molecule compounds that potently inhibit kallikrein activity in vitro. Kinetic studies indicate that some of these compounds are slow binding inhibitors of kallikrein with Ki final less than a nanomolar. The ability of these compounds to inhibit the activity of kallikrein was further confirmed in a plasma model by quantitating the release of bradykinin, an endogenous cleavage product of plasma kallikrein. To understand the inhibitory mechanism of the selected compounds toward kallikrein, the interactions between the selected compounds and kallikrein was explored using molecular modeling based on the information of crystal structures of TF/FVIIa and kallikrein. The information presented in the current study provides an initial approach to develop more selective and therapeutically useful small molecule inhibitors.

Measurement of direct photon production in p+p collisions at sqrt[s] = 200 GeV

Cross sections for midrapidity production of direct photons in p+p collisions at the Relativistic Heavy Ion Collider (RHIC) are reported for transverse momenta of 3 < pT < 16 GeV/c. Next-to-leading order perturbative QCD (pQCD) describes the data well for pT >5 GeV/c, where the uncertainties of the measurement and theory are comparable. We also report on the effect of requiring the photons to be isolated from parton jet energy. The observed fraction of isolated photons is well described by pQCD for pT >7 GeV/c.

Effects of caffeine on levodopa pharmacokinetics and pharmacodynamics in Parkinson disease

The authors studied the acute effect of caffeine on the levodopa pharmacokinetics and pharmacodynamics in 12 patients with idiopathic Parkinson disease. This double-blind, randomized, crossover study revealed that caffeine shortened the maximal plasma concentration of levodopa, decreased the latency to levodopa walking and tapping motor response, and increased the magnitude of walking response. Caffeine administered before levodopa may improve its pharmacokinetics in some parkinsonian patients.

Dense-medium modifications to jet-induced hadron pair distributions in Au+Au collisions at sqrt s NN=200 GeV

Azimuthal correlations of jet-induced high-p(T) charged hadron pairs are studied at midrapidity in Au+Au collisions at sqrt[s(NN)]=200 GeV. The distribution of jet-associated partner hadrons (1.0<p(T)<2.5 GeV/c) per trigger hadron (2.5<p(T)<4.0 GeV/c) is found to vary with collision centrality, in both shape and yield, indicating a significant effect of the nuclear collision medium on the jet fragmentation process.

Azimuthal angle correlations for rapidity separated Hadron pairs in d+Au collisions at square root of sNN=200 GeV

Deuteron-gold (d+Au) collisions at the Relativistic Heavy Ion Collider provide ideal platforms for testing QCD theories in dense nuclear matter at high energy. In particular, models suggesting strong saturation effects for partons carrying small nucleon momentum fraction (x) predict modifications to jet production at forward rapidity (deuteron-going direction) in d+Au collisions. We report on two-particle azimuthal angle correlations between charged hadrons at forward/backward (deuteron/gold going direction) rapidity and charged hadrons at midrapidity in d+Au and p+p collisions at square root of sNN=200 GeV. Jet structures observed in the correlations are quantified in terms of the conditional yield and angular width of away-side partners. The kinematic region studied here samples partons in the gold nucleus with x~0.1 to ~0.01. Within this range, we find no x dependence of the jet structure in d+Au collisions.

A novel locus for hereditary spastic paraplegia with thin corpus callosum and epilepsy

BACKGROUND

Hereditary spastic paraplegia (HSP) are classified clinically as pure when progressive spasticity occurs in isolation or complicated when other neurologic abnormalities are present. At least 22 genetic loci have been linked to HSP, 8 of which are autosomal recessive (ARHSP). HSP complicated with the presence of thin corpus callosum (HSP-TCC) is a common subtype of HSP. One genetic locus has been identified on chromosome 15q13-q15 (SPG11) for HSP-TCC, but some HSP-TCC families have not been linked to this locus.

METHODS

The authors characterized two families clinically and radiologically and performed a genome-wide scan and linkage analysis.

RESULTS

The two families had complicated ARHSP. The affected individuals in Family A had thin corpus callosum and mental retardation, whereas in Family B two of three affected individuals had epilepsy. In both families linkage analysis identified a locus on chromosome 8 between markers D8S1820 and D8S532 with the highest combined lod score of 7.077 at marker D8S505. This 9 cM interval located on 8p12-p11.21 represents a new locus for ARHSP-TCC. Neuregulin and KIF13B genes, located within this interval, are interesting functional candidate genes for this HSP form.

CONCLUSION

Two consanguineous families with complicated autosomal recessive hereditary spastic paraplegia were clinically characterized and genetically mapped to a new locus on 8p12-p11.21.

Common suppression pattern of eta and pi0 mesons at high transverse momentum in Au + Au collisions at square root S(NN) = 200 GeV

Inclusive transverse momentum spectra of eta mesons have been measured within p(T) = 2-10 GeV/c at midrapidity by the PHENIX experiment in Au + Au collisions at square root S(NN) = 200 GeV. In central Au+Au the eta yields are significantly suppressed compared to peripheral Au + Au, d + Au, and p + p yields scaled by the corresponding number of nucleon-nucleon collisions. The magnitude, centrality, and p(T) dependence of the suppression is common, within errors, for eta and pi0. The ratio of eta to pi0 spectra at high p(T) amounts to 0.40 < R(eta/pi)0 < 0.48 for the three systems, in agreement with the world average measured in hadronic and nuclear reactions and, at large scaled momentum, in e+e- collisions.

Single electrons from heavy-flavor decays in collisions at

The invariant differential cross section for inclusive electron production in p+p collisions at [FORMULA: SEE TEXT] has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider over the transverse momentum range 0.4<or=pT<OR=5.0 GeV/c in the central rapidity region ([FORMULA: SEE TEXT]). The contribution to the inclusive electron spectrum from semileptonic decays of hadrons carrying heavy flavor, i.e., charm quarks or, at high , bottom quarks, is determined via three independent methods. The resulting electron spectrum from heavy-flavor decays is compared to recent leading and next-to-leading order perturbative QCD calculations. The total cross section of charm quark-antiquark pair production is determined to be [FORMULA: SEE TEXT].

Measurement of identified and inclusive photon second-harmonic parameter and implications for direct photon production in [FORMULA: SEE TEXT] Au+Au

The azimuthal distribution of identified pi0 and inclusive photons has been measured in [FORMULA: SEE TEXT] Au+Au collisions with the PHENIX experiment at the Relativistic Heavy-Ion Collider (RHIC). The second-harmonic parameter (nu2) was measured to describe the observed anisotropy of the azimuthal distribution. The measured inclusive photon is consistent with the value expected for the photons from hadron decay and is also consistent with the lack of direct photon signal over the measured pT range 1-6 GeV/c. An attempt is made to extract nu2 of direct photons.

Nuclear modification of electron spectra and implications for heavy quark energy loss in Au+Au collisions at [FORMULA: SEE TEXT]

The PHENIX experiment has measured midrapidity ([FORMULA: SEE TEXT]) transverse momentum spectra ([FORMULA: SEE TEXT]) of electrons as a function of centrality in Au+Au collisions at [FORMULA: SEE TEXT]. Contributions from photon conversions and from light hadron decays, mainly Dalitz decays of pi0 and eta mesons, were removed. The resulting nonphotonic electron spectra are primarily due to the semileptonic decays of hadrons carrying heavy quarks. Nuclear modification factors were determined by comparison to nonphotonic electrons in p+p collisions. A significant suppression of electrons at high pT is observed in central Au+Au collisions, indicating substantial energy loss of heavy quarks.

J/psi production and nuclear effects for d + Au and p + p collisions at square root of S(NN) = 200 GeV

J/psi production in d + Au and p + p collisions at square root of S(NN) = 200 GeV has been measured by the PHENIX experiment at rapidities -2.2 < y < +2.4. The cross sections and nuclear dependence of J/psi production versus rapidity, transverse momentum, and centrality are obtained and compared to lower energy p + A results and to theoretical models. The observed nuclear dependence in d + Au collisions is found to be modest, suggesting that the absorption in the final state is weak and the shadowing of the gluon distributions is small and consistent with Dokshitzer-Gribov-Lipatov-Altarelli-Parisi-based parametrizations that fit deep-inelastic scattering and Drell-Yan data at lower energies.

Measurement of transverse single-spin asymmetries for midrapidity production of neutral pions and charged hadrons in polarized p + p collisions at square root(s) = 200 GeV

Transverse single-spin asymmetries to probe the transverse-spin structure of the proton have been measured for neutral pions and nonidentified charged hadrons from polarized proton-proton collisions at midrapidity and square root(s) = 200 GeV. The data cover a transverse momentum (pT) range 1.0-5.0 GeV/c for neutral pions and 0.5-5.0 GeV/c for charged hadrons, at a Feynman-x value of approximately zero. The asymmetries seen in this previously unexplored kinematic region are consistent with zero within errors of a few percent. In addition, the inclusive charged hadron cross section at midrapidity from 0.5 < pT < 7.0 GeV/c is presented and compared to next-to-leading order perturbative QCD (pQCD) calculations. Successful description of the unpolarized cross section above approximately 2 GeV/c suggests that pQCD is applicable in the interpretation of the asymmetry results in the relevant kinematic range.
