Transmission of Squash vein yellowing virus to and From Cucurbit Weeds and Effects on Sweetpotato Whitefly (Hemiptera: Aleyrodidae) Behavior

Since 2003, growers of Florida watermelon [Citrullus lanatus (Thunb.) Matsum. and Nakai] have periodically suffered large losses from a disease caused by Squash vein yellowing virus (SqVYV), which is transmitted by the whitefly Middle East-Asia Minor 1 (MEAM1), formerly Bemisia tabaci (Gennadius) biotype B. Common cucurbit weeds like balsam apple (Momordica charantia L.) and smellmelon [Cucumis melo var. dudaim (L.) Naud.] are natural hosts of SqVYV, and creeping cucumber (Melothria pendula L.) is an experimental host. Study objectives were to compare these weeds and 'Mickylee' watermelon as sources of inoculum for SqVYV via MEAM1 transmission, to determine weed susceptibility to SqVYV, and to evaluate whitefly settling and oviposition behaviors on infected vs. mock-inoculated (inoculated with buffer only) creeping cucumber leaves. We found that the lowest percentage of watermelon recipient plants was infected when balsam apple was used as a source of inoculum. Watermelon was more susceptible to infection than balsam apple or smellmelon. However, all weed species were equally susceptible to SqVYV when inoculated by whitefly. For the first 5 h after release, whiteflies had no preference to settle on infected vs. mock-inoculated creeping cucumber leaves. After 24 h, whiteflies preferred to settle on mock-inoculated leaves, and more eggs were laid on mock-inoculated creeping cucumber leaves than on SqVYV-infected leaves. The transmission experiments (source of inoculum and susceptibility) show these weed species as potential inoculum sources of the virus. The changing settling preference of whiteflies from infected to mock-inoculated plants could lead to rapid spread of virus in the agroecosystem.

Permanent Teeth Emergence Time and Sequence in Children of Kavre District, Nepal

Background Population specific standards on the timing and sequence of emergence of permanent teeth are essential in planning dental care for children. There is only a single study on the emergence of permanent teeth in Nepalese children. Objective To determine the standards for permanent teeth emergence time and sequence in children of Kavre district, Nepal. Method A descriptive cross sectional study was conducted in 623 children of age 5 to 14 years from six different schools of Kavre district. The number of permanent tooth erupted except third molar was recorded along with age and gender. Data were analysed using SPSS 20.0. Descriptive statistics was used to determine the number and percentage of permanent teeth emerged at different ages and the mean age of emergence of each tooth. Student 't' test was used to determine the inter jaw differences in the mean age of emergence of each tooth. Result The study population constituted 50.7% boys and 49.3% girls of the total sample. The first tooth to emerge was mandibular first molar, whereas maxillary second molar tended to be the last to emerge in both the genders. Though in general, mandibular teeth tended to precede the corresponding maxillary teeth in emergence but significantly only mandibular central, lateral and second premolar emerged earlier than maxillary.( p ≤ 0.05) Conclusion This study can be used as a reference data for clinical and academic purpose especially for the children of Kavre district, Nepal.

Successful Management of Quadruplet Pregnancy following Spontaneous Conception

Introduction: When more than two fetuses simultaneously develop in the uterus, it is called higher order multiple pregnancy. The incidence of such pregnancies ranges from 0.01% to 0.07%.   Case report: We report a case of 26-year-old G2P1L0D2 with previous history of preterm vaginal twin delivery, diagnosed to have quadruplet pregnancy. She was admitted at 28 weeks of gestation for safe confinement. At 33 weeks of gestation, emergency cesarean section was conducted with outcome of two female and two male babies with quadriamniotic and quadrichorionic placenta, without any intra and post-operative complications.   Conclusion: A multidisciplinary approach with good neonatal care facilities is warranted for a better outcome in higher order multiple pregnancies.

Prevalence of Extended Spectrum Beta-Lactamase Producing Klebsiella Pneumoniae Isolated From Urinary Tract Infected Patients

BACKGROUND

Klebsiella pneumoniae, one of the bacterial agents associated with urinary tract infection has been often implicated as a major extended spectrum beta-lactamase (ESBL) producer in last few decades. This study was designed to assess the prevalence of ESBL producing Klebsiella pneumoniae in urinary isolates at a tertiary care hospital in Kathmandu, Nepal, from July to December 2014.

METHODS

One thousand nine hundred eighty six mid-stream urine specimens were collected aseptically from the clinically suspected patients of urinary tract infections attending Capital Hospital and Research Center, Kathmandu. The samples were processed following standard guidelines as recommended by American Society for Microbiology (ASM) and the isolates including Klebsiella spp. were identified using the specific biochemical and sugar fermentation tests recommended by ASM. Antibiotic sensitivity testing was done by modified Kirby-Bauer disk diffusion method and interpreted following Clinical and Laboratory Standards Institute (CLSI) guidelines. Klebsiella pneumoniae isolates showing resistance upon initial screening with ceftriaxone (30 μg) disc were then confirmed for ESBL production by phenotypic confirmatory disc diffusion test (PCDDT) using ceftazidime (30 µg) and ceftazidime + clavulanic acid (30 µg + 10µg) and cefotaxime (30 µg) and cefotaxime + clavulanic acid (30 µg +10µg) disc as per CLSI guidelines.

RESULTS

Out of a total 1986 specimens investigated, Escherichia coli was isolated in 309 (83.9%) and Klebsiella pneumoniae in 38 (10.3%) cases. Initial screening with ceftriaxone disc revealed 18 isolates of Klebsiella pneumoniae to be resistant. Further testing by PCDDT method confirmed 7 (18.4%) Klebsiella pneumoniae isolates to be ESBL producers.

CONCLUSIONS

Compared to some earlier studies done in Nepal, higher prevalence of ESBL-producing Klebsiella pneumoniae was observed warranting a national surveillance for routine monitoring of ESBL producing Klebsiella pneumoniae isolates.

Acetabular Fracture: Retrospective Analysis of Thirty Three Consecutive Cases with Operative Management

BACKGROUND

With the development of better imaging modalities including 3D CT scan and availability of technical expertise, operative management is increasingly performed for acetabular fracture but many patients in developing countries like Nepal, are still being treated with prolonged skeletal traction.

OBJECTIVE

To analyses epidemiology, types of acetabular fracture and functional and radiological outcome of patients with acetabular fracture treated with open reduction and internal fixation (ORIF).

METHOD

Inpatients hospital records of patients treated with ORIF in between June 2007 to June 2014 were evaluated. Patient's demographic data, mode of injury, injury hospital interval, injury surgery interval, associated injuries, surgical approach, total hospital stay and peri and post-operative complications were recorded and radiological and functional outcomes were evaluated.

RESULT

Thirty three patients (Male: 24 Female: 9) with average age 39 years (range: 21 to 65 years) were operated for acetabular fracture. Twenty one patients (63%) had injury related with motor vehicle accidents and nine (24%) of them had motorbike accidents. Injury hospital interval ranges from 7 to 36 days. Average injury-surgery interval was 21 days and average hospital stay was 22 days. Bicolumnar fractures were found in 15. Nine patients had dislocation of hip and 15 had concomitant other injuries. Biculumanr fixation was performed in 15 patients, posterior column and or wall in nine with Kocher Langenbeck approach and anterior column and or wall in other nine with ilio-inguinal approach. Radiological reduction was anatomical in 18; excellent/good functional outcome was in 26 and radiological outcomes were excellent in 14. Three patients had developed Hypertopic ossification. Follow up period ranged from 6 to 48 months and 15 patients (45%) had follow up >2 years.

CONCLUSION

Acetabular fractur can be effectively managed with ORIF and have predictable and comparable functional and radiographic outcomes. Upgrading the existing facilities and training of orthopedic surgeon for acetabular fracture management is important to shorten injury-surgery interval due to lack of such facilities.

Abstract P4-01-07: Recall for assessment after post-treatment surveillance mammograms in breast cancer

Background: Patients treated for breast carcinoma are usually followed up with regular mammograms. The aims are early diagnosis of locally recurrent disease in the ipsilateral breast or new cancers in the contralateral breast, and to provide reassurance. When the mammograms are considered abnormal patients are recalled for further assessment. The aim of this study is to review all mammographic recalls in a single institution over a 5-year period to study the patient population recalled, reasons for the recall and the outcome.

Materials and Methods: We identified all breast cancer patients who were recalled for assessment following a routine post-treatment surveillance mammogram from April 2010 to March 2015 from the breast unit database. We reviewed their original presentation with breast cancer, treatment received, reason for recall, the assessment process and the outcome. The mammographic follow-up policy of the unit during the study period was as follows; after breast conserving surgery (BCS), yearly bilateral mammograms for 5 years or until the age of 50 whichever the later; following mastectomy, mammogram of the opposite breast at years 1, 3 and 5 post-surgery, and if the patient is aged under 50 after 5 years, 2-yearly till 50 years of age. Patients were then discharged to UK National Breast Screening Programme where mammograms are performed 3-yearly.

Results: During the study period 1809 patients had 3685 surveillance mammograms. 149 patients were recalled (a recall rate of 8% of patients and 4% of mammograms over 5-years). 122 patients had BCS and 27 patients had mastectomy. The original diagnosis was invasive cancer in 131 and DCIS in 18. The reason for recall was a density or mass in 63, microcalcification in 61, distortion in 14 and a mixture of these or other reasons in 11. Eighty one patients were recalled for a problem on the ipsilateral side and 66 for contralateral side (2 patients had bilateral cancer).

Among 149 patients recalled, 50 had further imaging only (further mammographic views, ultrasound or both) after the recall and 79 underwent a needle biopsy under ultrasound or stereo guidance. 8 patients underwent US-guided aspiration of benign cysts. 21 biopsy results were malignant. The final diagnosis was ipsilateral recurrence in 10 patients and contralateral cancer in 11.

Conclusions: There is not much published data in the literature on the outcome of post-treatment surveillance mammograms despite the fact that such mammographic surveillance is commonly practiced. This study shows that over a 5-year period, 8% of the patients and 4% of the mammograms were recalled. A third of patients recalled only required further imaging. Although biopsies were performed in over half the patients, only 14% of patients recalled were proved to have ipsilateral or contralateral carcinoma after the assessment.

Assessment of Knowledge Regarding Oral Hygiene among Parents of Pre-School Children Attending Pediatric Out Patient Department in Dhulikhel Hospital

BACKGROUND

Level of knowledge regarding oral hygiene among the parents of pre-school children plays an important role on maintaining the good oral hygiene of their children. In Nepal, sufficient research has not been carried out on this area.

OBJECTIVE

Objective of this study is to assess the level of knowledge on oral hygiene of preschool children's parents attending pediatric outpatient department in Dhulikhel Hospital.

METHOD

A descriptive study was conducted from November 2012 to January 2013 among one hundred parents of preschool children visiting pediatrics outpatient department of Dhulikhel Hospital. Paper and pencil based semi structured questionnaire was used for collecting data. Questions related to demographic information and knowledge were asked. Thirty questions were used for assessing knowledge level. Knowledge score was calculated by allocating one point for each correct answer and zero point for each wrong answer. Analyzed data were presented in terms of numbers and percentages. Total knowledge scores were categorized based on percentage. Knowledge score was categorized on four group - exclusive intervals - namely-poor (0-40%), moderate (40-60%), good (60-80%) and excellent (80-100%). Mann-Whitney U test and Kruskal-Wallis test were applied to check significance difference and chisquare test was used to check association among different background characteristic.

RESULT

It was found that 81% had moderate knowledge, 15% had poor knowledge and 4% had good knowledge about oral hygiene. Median knowledge score was found to be 15 with range 10 to 21. Following variables were found to be significant difference on knowledge category: Education status (p<0.001), education level (p= 0.041), past experience about oral health problem (p = 0.008), Further significant association was found between knowledge category and educational status (p<0.001) and between knowledge category and past experience (p< 0.001).

CONCLUSION

Knowledge regarding oral hygiene was found satisfactory among the parents of preschool children visiting pediatric OPD of Dhulikhel Hospital.

Percutaneous Ilio-Sacral Screw Fixation in Supine Position under Fluoroscopy Guidance

Background Pelvic ring disruption when treated conservatively can be associated with prolonged hospital stay and immobilization, mal-union, chronic pain, limb length discrepancy if they are treated conservatively. Open reduction and fixation in an already compromised soft tissue and hemodynamically unstable patient causes more soft tissue injury, heamatoma, infection and neurovascular injury. Percutaneous ilio-sacral joint fixation can be an alternative technique for sacro-iliac joint injury and sacral fracture.Objective To evaluate technique and safety of percutaneous ilio-sacral screw fixation in supine position under single fluoroscopy guidance for sacral fracture and sacro-iliac joint disruption.Method Twenty one patients either with sacral fracture or sacro-iliac joint disruption with percutaneous ilio-sacral screw fixation with cannulated cancellous screw fixation in between 2008 to 2014 were retrospectively evaluated including AP, inlet and outlet views of pelvis X rays and CT scan. Tile’s classification and Dennis classification were used for pelvis and sacral injury.Result Thirty five percutaneous ilio-sacral screws were placed (Male: 6, Female: 15; range: 15 to 54) for sacral fracture involving zone 2 (8 with sacral fracture only and 5 with pelvis injury; Tile’s type B in four and type C in one) and sacro-iliac joint injury (Tile’s type B in three and type C in five). Commonest mode of injury was motor vehicle accidents (10) followed by fall related injury (6). Injury hospital interval and injury surgery interval was five hours to 13 days and 2 to 20 days respectively. Follow period was 3 months to 6 years. One patient developed post-operative deep vein thrombosis and another patient had post-operative haematoma. Two screws were juxtra-foramial. Good to excellent outcome were in 16 patients, fair in four and poor in one patient (Majeed Scoring).Conclusion Percutaneous ilio-sacral screw fixation for sacro-iliac joint injury and sacral fracture with C arm guidance is safe and minimally invasive technique. Clear images and accurate interpretation of X-rays, CT scans and per operative C arm images are important to avoid malpositioning of screws and iatrogenic neurovascular injuries.Kathmandu University Medical Journal Vol.13(1) 2015; 56-60

Pattern of Sleep in Infants and Toddlers Visiting at a Teaching Hospital in Lalitpur

Introduction: Sleep is an integral part in a child’s health and development. During different stages of development, there are aberrations in normal physiology of sleep which make children more susceptible to various types of sleep problems. This study was conducted to identify sleep pattern and sleep problems in Nepalese children using Nepali translation of Brief Infant Sleep Questionnaire (BISQ) screening tool.Materials and Methods: This was a descriptive cross-sectional study. Data were collected from parents of children aged 6 to 36 months attending paediatric out-patient clinic for general health check-up from July 2013 to December 2013. Nepali translation of the BISQ was used as a screening tool for sleep problems in this study.Results: The study included 553 children (52.4% boys). Mothers completed the questionnaire in 92% of children. Mean total duration of sleep in 24 hours was 11.7 ±1.7 hours. Respondents reported sleep problem in 16.9% of children whereas 20.3% of children had sleep problems according to BISQ criteria. As per this criteria, 2.7% of children had total sleep duration less than 9 hours, 5.9% of children had total night awakening duration of more than one hour, 13.9% of children had night waking >3 times. These BISQ sleep parameters differed significantly in children with and without sleep problems (p<0.001). In addition, children with sleep problem took longer time to sleep than children without sleep problems (p<0.001).Conclusion: Sleep problems are common in Nepalese infants and toddlers according to the BISQ. Screening for sleep problems is highly recommended during health care visits given the prevalence of sleep problems identified by this study to reduce their potential adverse impact.J Nepal Paediatr Soc 2015;35(1):24-30

The Incidence of Thyroid Carcinoma in Multinodular Goiter: A Retrospective Study

Background and Objective: To determine the incidence and the types of various thyroid malignancies in multi-nodular goiter.Material and methods: This is a retrospective study, conducted in Department of ENT and Head and Neck Surgery, National Academy of Medical Sciences Bir Hospital Kathmandu and Alka Hospital Pvt. Ltd Lalitpur. The study period was 3 years from 11 January 2011 to 10 January 2014. The study population consisted of 100 patients who were diagnosed as a multinodular thyroid nodule.Result: The highest frequency was 50 (50%) in 31-40 years. Among the total cases, 28 (28%) were males and 72(72%) females. Histopathological analysis showed that benign multi-nodular goiter was present in 87 (87%) cases, and malignant thyroid lesion in 13 (13%) cases. Among malignancies, papillary carcinoma was found as the commonest malignancy 11 (84.61%) cases followed by follicular carcinoma 1 (7.69%) case and anaplastic carcinoma 1(7.69%) case.Conclusion: The risk of malignancy in multinodular goiter should not be underestimated as significant number of patients with thyroid malignancies present with multinodular goiter.JCMS Nepal 2014; 10(4):18-21

Epidemiological and Outcome Analysis of Orthopedic Implants Removal in Kathmandu University Hospital

Background Orthopedic Implant removal is one of the commonly performed elective orthopedic surgeries. Implants are generally removed after the purpose of keeping implant is solved by healing of the fracture, but there is no consensus whether routine implant removal should be a policy for all fractures that were fixed. Objective This study aims to analyze the epidemiology and outcome of implant removal surgery carried out in the past three years in Kathmandu University Hospital. Methods Patients who underwent implant removal between 2010 January to 2012 December constituted the study cohort. Demographic data, indications, types of hardware and location of fractures were recorded. Similarly, duration of surgery, type of anesthesia and duration of hospital stay were recorded. All the patients who had undergone implant removal in this three years period were called for follow up examination but those who were not able to come were interviewed on telephone. Results There were 275 implant removals constituting 7.8% of total orthopedic operations and 26.3% of fracture fixations. Male to Female ratio was 189: 86. Pediatric age group (34.5%) had the highest incidence of implant removal. Moderate sized implants were the commonest hardwares removed (63.2%). Femur (27.3%) followed by radius (26.9%) were the commonest bone for implant removal. Average operative time was 47.3 minutes with average hospital inpatient stay of 2.6 days. Commonest indication for the implant removal procedure was pain (45%). Conclusion Implant removal procedures are one of the most commonly performed elective orthopedic surgeries. Though, after orthopedic implants removal, pain relief can be expected but it is not so predictive and hence patient should be well counseled before and the indications for implant removal has to be evaluated for better patient satisfaction and safety.

Instrumentation in cervical spine injury: neurological outcome measurement using ASIA impairment scale

Cervical spinal cord injuries make up more than half of all spinal cord injuries. It affects 2-3% of all trauma patients and accounts for 8.2% of all trauma related deaths. Cervical spine surgery has been evolving in terms of surgical technique, equipment, and instrumentation. We have analyzed a series of patients with cervical spine injuries stabilized with various instrumentation techniques. The objective of the study was to evaluate the outcome of instrumentation in cervical spine injury measured on ASIA Impairment Scale. We present prospective observational descriptive analysis, for 36 patients, looking at the clinical and neurological outcomes following instrumentation for cervical spine injuries from Jun 2011 to July 2013. All 36 patients underwent various instrumentation techniques for stabilization and decompression of the cervical spinal cord. The outcome was compared by the ASIA impairment scale. There were 27 (75%) males and 9 (25%) females. The mean age at presentation was 46 years (17-74 years). The most common mode of injury was fall (62%), with ASIA grade C and D, 31% each. C5/6 level was the most common level (26.2%) of injury. The timing of surgery ranged between 8 - 270 days from injury. Out of thirty-six, thirty-two patients were available for follow-up. Eighteen of these patients had spinal cord injury and improved by at least one ASIA grade. It is concluded that instrumentation in cervical spine injury is an effective surgical procedure with minimal post-operative morbidity for the management of cervical injury, allowing an improved physiologic environment for maximal neurologic improvement. The post-operative outcome measured on ASIA impairment scale was comparable to international study.

Clinical Profile of Acute Poisoning in Children at a Teaching Hospital in Lalitpur

Introduction: Acute poisonings are one of the common cause of emergency visits and hospital admissions and is potentially preventable cause of childhood mortality and morbidity. The objectives of this study were to identify the common type of poisoning in children, to determine types of poisoning according to age and to find out the common age group in which the incidence of poisoning was high.Materials and Methods: It was a descriptive observational study done in a teaching hospital in Lalitpur, Nepal in patients aged 1 month to 18 years who visited the emergency department and were admitted to hospital with history of alleged poisoning from 2009 July to 2014 January.Results: Fifty patients were included. Drugs, kerosene and organophosphorus were most common cause of poisoning. Drugs and kerosene below 10 years of age and organophosphorus and drugs above 10 years of age were common types of poisoning. Maximum numbers (50%) of children with poisoning cases were below five year of age. Mean duration of hospital stay was 2.1days and mean age of poisoning was 7.8 years with a male(54%) predominance. Majority of poisoning occurred at home (84%) and 68% of patients were symptomatic at presentation to hospital with 84% of patients presenting to hospital within six hours.Conclusion: This study showed that drugs, kerosene and organophosphorus were most common forms of poisoning. Young children were most vulnerable for acute poisoning.DOI: http://dx.doi.org/10.3126/jnps.v34i2.10139J Nepal Paediatr Soc 2014;34(2):100-103 

Clinical characteristics of children with febrile seizure

BACKGROUND

Febrile seizure is common in children below five years of age. This study was conducted to evaluate the clinical profile of children presenting with febrile seizure in a teaching hospital.

METHODS

This was a descriptive retrospective study among children presenting with febrile seizure in a teaching hospital from July 2009 to June 2013. Children between six months to six years were included in the study while patients with prior episodes of afebrile seizures, abnormal neurodevelopment and not meeting the age criteria were excluded. Patient's demographic and clinical data were collected from the in-patients records and analyzed.

RESULTS

This study included 103 children with febrile seizure. Out of which 67% were male. Simple febrile seizure and complex febrile seizure were observed in 76.7% and 23.3% of patients respectively. Majority of children (71.8%)had generalized tonic clonic seizure followed by tonic seizures. Most of children (72.8%) who developed first episode of seizure were below 24 months of age with the mean age of 20.7 (±12.1) months. Overall 33% of patients developed recurrence of febrile seizure and first episode of febrile seizure at age one year or below was associated with the seizure recurrence. Upper respiratory tract infections were the commonest cause of fever in these children.

CONCLUSIONS

Febrile seizure was observed predominantly in children below age of two years and simple febrile seizure was the ommonest variety. Recurrence of febrile seizure was common and significantly associated with the first episode of febrile seizure at the age of one year or below.

A comparative study on epidemiology, spectrum and outcome analysis of physical trauma cases presenting to emergency department of Dhulikhel Hospital, Kathmandu University Hospital and its outreach centers in rural area

BACKGROUND

Physical trauma is one of the major cause of mortality and morbidity among young and active age group and its increasing trend is of main concern. There are only few studies concerning the spectrum of physical trauma in Nepal.

OBJECTIVE

This study aims to evaluate the epidemiological spectrum, the extent, severity of the physical trauma and the outcome evaluation of patients with physical trauma over a period of one year in the emergency department of the Kathmandu University Hospital and compare the same parameters with those patients presenting to the various outreach centers of the hospital in the community.

METHODS

Patient treatment files from the emergency department and the reports from various outreach centers were retrieved for a period of one year (May 2011 to April 2012). Epidemiological information, mode, type and anatomic location of injuries were recorded. Outcome evaluation was assessed by number of patients discharged from emergency department of the hospital or the outreach centers after the treatment, patients admitted for inpatient management and referred to other centers for further specialty management.

RESULT

In a period of one year, total 2205 (20%) of physical trauma cases presented to the emergency department and 1994 (6.12%) in the outreach centres. Most commonly involved age group in physical trauma both in Hospital set up and in Community set up were the young adults (15 to 49 years). Fall from height was the commonest mode of injury followed by road traffic accidents among the patients coming to the hospital while significant number of trauma patients coming to outreach centers were due to fall from height. In the hospital set up, 1525 (69.2%) of the cases were discharged while 537 (24.4%) needed inpatient management and 85 (3.8%) needed referral to other centers for the specialty management. In case of outreaches, half of the patients were discharged after the primary treatment and almost another half were referred to the hospital, mainly for need of further investigations.

CONCLUSION

Fall related injuries and road traffic accidents are the most common mode of trauma in the hospital set up and fall related injuries are the single most important mode of trauma seen in the outreaches. Mostly young adults in their active period of life are involved in physical trauma so appropriate preventive measures through public health approach should be included in comprehensive trauma management for reducing mortality and morbidity rates related to physical trauma.

Association between Serum Antibodies to Oral Microorganisms and Hyperglycemia in Adults

We conducted a cross-sectional analysis to evaluate the relationship between serum antibody titers against 19 selected oral microorganisms and measures of hyperglycemia in a large, nationally representative data set. The study population consisted of 7,848 participants from the National Health and Nutrition Examination Survey III (1988-1994) who were at least 40 yrs old, with complete serum IgG antibody data against 19 oral microorganisms. The 19 antibody titers were grouped into 4 categories via cluster analysis--orange-red, yellow-orange, orange-blue, and red-green--named to reflect predominant antibody titers against microorganisms in Socransky's classification scheme for oral microbes. Linear regression models weighted for complex survey design were used in which fasting blood glucose, fasting insulin, and HbA1c were outcomes and antibody cluster scores were exposures, adjusting for potential confounders. Higher orange-red cluster scores were associated with increased hyperglycemia, while higher orange-blue cluster scores were related with decreased hyperglycemia. A 1-unit-higher orange-red cluster score was associated with 0.46 mg/dL higher fasting blood glucose (p = .0038), and a 1-unit-higher orange-blue cluster score was associated with 0.34% lower HbA1c (p = .0257). Groups of antibody titers against periodontal microorganisms were associated with hyperglycemia independent of known risk factors.

Interactions among potato genotypes, growth stages, virus strains, and inoculation methods in the potato virus Y and green peach aphid pathosystem

Potato virus Y (PVY) is an economically important and reemerging potato pathogen in North America. PVY infection reduces yield, and some necrotic and recombinant strains render tubers unmarketable. Although PVY(O) is the most prevalent strain in the United States, the necrotic and recombinant strains PVY(NTN) and PVY(N:O) are becoming more widespread. Infection rates in aphid-inoculated (Myzus persicae (Sulzer)) and mechanically inoculated plants were compared across two potato genotypes ('Yukon Gold' and A98345-1), three PVY strains (PVY(O), PVY(N:O), and PVY(NTN)), and two growth stages at inoculation (pre- and postflowering). Susceptibility of genotypes was measured as infection rate using a double-antibody sandwich-enzyme-linked immunosorbent assay; virus titer and tuber mass also were recorded from the infected plants. Yukon Gold generally was more susceptible than A98345-1 to all three PVY strains, especially following mechanical inoculation. Within genotypes, Yukon Gold was most susceptible to PVY(O) and A98345-1 was most susceptible to PVY(N:O). Plants exhibited age-based resistance, with both genotypes showing higher susceptibility at the pre- than postflowering stage. The overall ranking pattern of virus titer in infected plants was PVY(O) > PVY(NTN) > PVY(N:O); across all three strains, infected Yukon Gold had higher titer than infected A98345-1 plants. Yukon Gold plants had lower tuber mass than A98345-1 when infected, and there were differences between the two inoculation methods in regard to tuber mass for the three stains. The results showed differences in infection response between inoculation methods and as a function of genotype, strain, inoculation stage, and their interactions. These factors should be considered when screening genotypes for resistance.

Human genital myiasisin extremes of age

Genital myiasis is a very rare entity associated with poor personal hygiene, restricted mobility, and immunosuppressed status and ulcerating lesions. With the reported incidence of only 0.7%, only a few cases have been published so far in literature but none from Nepal. Despite such rare occurrence, we present here two such cases which we encountered in an interval of three days; one in an unmarried teenager and another in a postmenopausal lady with fungating ulcerative growth of vulval carcinoma. Both were successfully managed.

An endodontic practice profile amongst general dental practitioners in Kathmandu: A questionnaire survey

Objective To investigate the endodontic practice profile of general dental practitioners. To explore the materials and methods employed by them in Kathmandu valley. To compare these findings with well acknowledged international academic standards. Methods Questionnaires with 18 closed-ended questions were distributed among randomly chosen 120 general dental practitioners of Kathmandu, working in various government or private hospital or clinics.The data were collected and descriptive statistical analysis was done. Results Out of 120 questionnaires, only 110 that were completely filled were included in the study .Most general dental practitioners (97%) regularly did multi-rooted root canal treatments and followed multivisit root canal treatment.. Radiograph with instrument in canal was used by 80% of general dental practitioners to determine the working length while only 36% used electronic apex locator which is considered to be more reliable. Half of them (57%) used nickel-titanium files for cleaning and shaping but only 23% used crown down technique. Sodium hypochlorite and calcium hydroxide was the most popular irrigation solution and intra-canal medicament respectively. Majority of general dental practitioners (91%) used lateral compaction technique for root canal obturation. Sixty three percent used zinc oxide eugenol as root canal sealer and 46% used endomethasone. They seem to overuse antibiotics in cases requiring endodontic therapy. Only 48% used autoclave for sterilization of endodontic files while 86% never used rubber dam. Eight three percent of them felt the need of further endodontic training and 42% of them preferred post-graduate dental program. Conclusion This study shows that the standard guidelines and new technologies for endodontic treatments are not implemented by many general dental practitioners of Kathmandu and require further endodontic trainings.
