First Report on Sergentomyia sintoni and Sergentomyia clydei (Diptera: Psychodidae): Their Natural Promastigote Infection and Some Aspects of Biology in Sistan-Baluchistan Province,Southeastern Iran

ObjectiveTo This paper has explained initial survey on two vectors of lizard leishmania promastigote in south-east of Iran.MethodsTotally 333 S. sintoni and 475 S. clydei were collected from rodent burrows by sticky traps in three villages of Chabahar County. Sand flies were dissected in a drop of normal saline.ResultsNatural leptomonad infection rate involved %2.1 S. sintoni and %5 S. clydei. The finding about seasonal variation was showed the highest infection rate in two vectors in the first week of August. The highest population of gravid and semi-gravid of main vectors of Lizard leishmaniasis, S. sintoni and S. clydei, were observed in the last week of September and the lowest were in the last week of July. The examination of accessory glands showed that the maximum population of parous was observed in the last week of September and the last week of July it was at least. This is the first report of leptomonad (promastigote) infection in S. sintoni and S. clydei in Sistan-Baluchistan Province, southeastern Iran.ConclusionsA further study with more focus on biology of Sergentomyia genus is suggested.     

Hydrophilic polymer vasculopathy with coinciding pseudoxanthoma elasticum‐like changes in an amputated toe

For the past decades, hydrophilic polymer gel coating have been widely used on endovascular devices to decrease friction and to aid with binding and delivering of medications in drug‐eluting stents. In the recent years, hydrophilic polymer emboli disease has been recognized as an iatrogenic adverse effect which has led to considerable morbidity and mortality of patients. This under‐recognized embolic phenomenon now has reproducible pathognomonic histologic findings. Small‐ to medium‐sized blood vessels are occluded with basophilic, amorphous, non‐refractile, non‐polarizable and whirled aggregates of foreign body material. Depending on the affected organ, the patients have variable symptomatology, from livedo racemosa, gangrene of extremities to cardiac arrhythmias, hemiparesis, stroke and death. Here, we present a unique case of hydrophilic polymer vasculopathy 6 years post‐endovascular procedure with coinciding pseudoxanthoma elasticum‐like changes. As the literature has seen increased reporting of individual cases and case series documenting the patients’ diverse symptomatology; hydrophilic polymer vasculopathy should be entertained sooner in the patient's differential diagnosis.     

Effects of voice therapy as objectively evaluated by digitized laryngeal stroboscopic imaging

Objective measurements derived from digitized laryngeal stroboscopic images were used to demonstrate changes in vocal fold vibration and in the size of benign lesions after 3 months of voice therapy. Forty chronically dysphonic patients were studied. By means of a rigid stroboscope, pretreatment and posttreatment recordings were made of the vocal folds at rest and under stroboscopic light during phonation. From each recording, images of the positions at rest and during vibration at maximal opening and at maximal closure were digitized. The surface areas of any lesions and of the glottal gap were independently measured in the digitized images by 2 experienced laryngologists. Referential distances were determined in order to compensate for discrepancies in magnification in the various recordings. After 3 months of voice therapy, significant improvement in lesion size and degree of maximal closure during vibration could be demonstrated in about 50% of the patients. The degree of maximal opening did not prove to be a significant parameter.     

Effect of low-dose aspirin on the development of ovarian hyperstimulation syndrome and outcomes of assisted reproductive techniques in the women with PCOS,a randomized double-blinded clinical trial

Objective

Ovarian hyperstimulation syndrome (OHSS) is a major complication of assisted reproductive technologies (ART). Polycystic ovary syndrome (PCOS) is a risk factor for OHSS. The aim of this randomized clinical trial (RCT) was to study the effect of low-dose aspirin (LDA) on the development of OHSS and ART outcomes in PCOS during ART.

Association of first-trimester maternal lipid profiles and triglyceride-glucose index with the risk of gestational diabetes mellitus and large for gestational age newborn

Objective: To evaluate the association of maternal first-trimester plasma lipid profiles, fasting plasma glucose (FPG), and triglyceride (TyG) index with the risk of gestational diabetes mellitus (GDM) and large for gestational age (LGA) infant in Iranian mothers.

Methods: Nine hundred and fifty-four healthy pregnant women were prospectively followed till after delivery. Maternal fasting lipids and glucose concentration were measured at nine-week gestation on average. We used generalized linear models to calculate the relative risks and 95% confidence intervals.

Results: The incidence of GDM and LGA infants among our participants was 18.4% and 26.1%, respectively. There was a significant correlation between the increase in FPG, triglyceride, TG/HDL-C ratio, as well as TyG index with the risk of GDM and LGA infant. After adjusting for potential confounders, the relative risk of GDM in women in the top tertile of FPG, triglyceride (TG), triglyceride/high-density lipoprotein-cholesterol (TG/HDL-C) and TyG index was 4.2-, 4.2-, 3.9-, and 4.9-folds of its risk in women in the bottom tertile, respectively. Also after adjusting for GDM, the relative risk of LGA infants in women in the top tertile of FPG, TG, TG/HDL-C ratio and TyG index was 3.9-, 4.3-, 4.8-, and 5.3-folds of its risk in women in the bottom tertile, respectively.

Conclusions: Based on our findings, TyG index is more robust early predictors of GDM and LGA in Iranian women.     

An open trial of citalopram in children and adolescents with depression

OBJECTIVE: The aim of this study was to collect pilot data on the magnitude of effect and tolerability of citalopram in early-onset major depressive disorder (MDD). METHOD: This study was performed in two academic child and adolescent psychiatric clinics (2000 through 2002). Thirty children and adolescents, 8-17 years of age (mean age, 13.57 +/- 2.5), of both sexes (53.3% girls; 46.7% boys) and diagnosed with MDD by means of clinical psychiatric evaluation, Diagnostic Interview for Children and Adolescents (DICA) and the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria, were studied in an open-label clinical trial with 10-40 mg/day of citalopram for 6 weeks. The outcome measures were the Hamilton Depression Rating Scale (HDRS), the Children Global Assessment Scale (CGAS), and the New York State Psychiatric Institute side-effect form. RESULTS: Moderate (50%-70% change in HDRS and CGAS) to large (> 70% change in HDRS and CGAS) effect were seen in 91.7% of children (22/24). There were significant changes on HDRS (X = 22.78; t = -14.12; p < 0.000) and CGAS (X = 26.02; t = 9.68; p < 0.000) between baseline and the 6th week. Mild side effects were reported in 2 patients (8.3%). Adverse effects that contributed to discontinuation were nausea and vomiting in 3.3% (n = 1) of patients and unexpectedly switching to mania in 16.7% (n = 5) of patients. CONCLUSION: Citalopram may be an efficatious treatment in early-onset MDD. However, the high switch rate to mania warrants further investigations, as well as cautions, in using it.     

Integrating clinical practice guidelines into daily practice: impact of an interactive workshop on drafting of a written action plan for asthma patients

INTRODUCTION: Written action plans (WAPs) are instructions that enable asthmatics to manage their condition appropriately and are recommended by current asthma clinical practice guidelines (CPGs). However, general practitioners (GPs) rarely draft WAPs for their patients. An interactive, case-based workshop for asthma, combined with an objective structured clinical examination (OSCE), was developed to increase GPs' knowledge and use of WAPs in Québec. METHODS: The study compared 24 GPs receiving an OSCE preworkshop and 12 months post-workshop (group 1) with 16 GPs receiving an OSCE preworkshop and at 6 and 12 months post-workshop (group 2). Participants received no feedback on their OSCE performance. During the workshop, which presented a preformatted tool to aid drafting of the WAPs, all 40 GPs worked individually and in small groups to answer questions on a hypothetical clinical case and then discussed the responses with a facilitator and an asthma specialist. RESULTS: Only group 2 GPs showed a significant improvement in knowledge of WAPs 12 months post-workshop (p = .01). The likelihood of prescribing WAPs to patients increased in group 2 to a degree approaching statistical significance (p = .070), and there was a borderline nonsignificant trend for prescribing practice to improve more among group 2 GPs than among group 1 GPs (p = .052). There was also a nonsignificant trend for 6-month OSCE to increase attendance at the 12-month OSCE. DISCUSSION: An interactive workshop employing a preformatted WAP tool and a reinforcing OSCE at 6 months yielded improved knowledge of WAPs at 1 year. Although originally developed as a form of evaluation, the OSCE appears to have formative value even when correction is not provided and may increase the effectiveness of continuing medical education interventions to enhance CPG implementation.     

Comparison of functional and quality-of-life outcomes in patients with and without palatomaxillary reconstruction: a preliminary report

BACKGROUND: Orodental rehabilitation of hemipalatomaxillectomy defects can be accomplished by using a prosthetic obturator or a vascularized bone-containing free flap. Whereas prosthetic obturation offers several advantages, including the opportunity for immediate dental restoration without the need for further surgery, vascularized bone grafts provide permanent closure of the oronasal communication and bone sufficient for the placement of osseointegrated implants. OBJECTIVE: To compare the functional and quality-of-life (QOL) outcomes in patients rehabilitated with a prosthetic obturator with defect-matched patients who underwent reconstruction with a vascularized bone-containing free flap. METHODS: Four hemipalatomaxillectomy patients rehabilitated with a tissue-borne prosthetic obturator were compared with 4 defect-matched hemipalatomaxillectomy patients who underwent reconstruction with a vascularized bone-containing free flap. All of the patients were objectively assessed for speech, mastication, and QOL. Functional status was assessed by mastication testing, voice analysis, and nasorhinometry. Swallowing-related QOL was assessed using a patient-reported, validated swallowing QOL questionnaire, and donor site morbidity was assessed using upper extremity and lower extremity questionnaires. RESULTS: Patients who underwent reconstruction with a vascularized bone-containing free flap achieved higher mastication and speech assessment scores with less oronasal reflux than defect-matched patients rehabilitated with a prosthetic obturator. Swallowing QOL and donor site assessments demonstrated that compared with their prosthetic counterparts, reconstruction patients enjoyed a better QOL without incurring significant donor site morbidity. CONCLUSIONS: Although palatomaxillary reconstruction with vascularized bone-containing free flaps requires a second operative site, this method of orodental rehabilitation of the hemipalatomaxillectomy defect can achieve superior functional and QOL outcomes relative to defect-matched patients rehabilitated with a prosthetic obturator.
