Successful myomectomy during pregnancy

Leiomyoma is the most common benign tumor of the uterus and could complicate pregnancy. Here we present a case of leiomyoma in a nullipara women at the 24 th week of gestation complained of abdominal pain and nausea which was not responding to conservative therapies. A laparotomy was done and a 30*20 cm mass was resected from the uterus. She had a normal term delivery after the operation

Recurrent ectopic pregnancy in the fallopian tubes

Here, we present a case with several episodes of ectopic pregnancy in the fallopian tubes, which was treated by medical and surgical methods, and followed for two years until it ended in a term successful delivery

Ultrastructural and molecular characteristics of Setaria species based on sequence analysis of genomic and mitochondrial gene markers in cattle (Bos taurus) and buffaloes (Bubalus bubalis) from Iran

ΔΕΝ ΔΙΑΤΙΘΕΤΑΙ ΠΕΡΙΛΗΨΗThe aim of the present study was to investigate the ultrastructural characteristics and genetic diversity of Setaria parasites from cattle (n=696) and buffalo (n= 522) from Khuzestan province of Iran and to compare them with available data from other countries/regions by sequences analysis of the 12S Rdna and the mitochondrial cytochrome C oxidase subunit I (cox1) genes. Based on SEM (Scanning Electron Micrographs) and light microscopy, all the isolated worms were identified as Setaria labiatopapillosa. Our results showed that 12.3% of cattle were infected with Setaria spp., while no infection was found in buffaloes. The maximal prevalence was observed in cattle younger than one year old. The prevalence rate was not influenced by the season of the year or gender. Comparison of the obtained sequences from Setaria with sequences of Setaria spp. from GenBank confirmed that all samples belong to the species S. labiatopapillosa. The phylogenetic tree constructed using cox1 and 12S rDNA genes of several other filarial nematodes showed that the Khuzestan isolates share a common branch with S. labiatopapillosa from other regions. Intra-specific variation was observed in 12S rDNA but not in cox1. In conclusion, our results indicating that S. labiatopapillosa is the main species involved in the spread of setarial infection in south-west of Iran and the identified worms corresponded mostly to worms that reported previously throughout other continents

Cloning and Expression of Immunogenic Regions of EMA-1 Gene of Theileria equi From Infected Horses

Diversity among the pathogenic strains of Theileria equi (T. equi), a major agent of equine piroplasmosis, can affect the appropriate detection of parasite and host immunization. Production of recombinant surface proteins from an infected horse in natural endemic area provides a reliable tool for immunodiagnosis of parasite. Regarding this, the present study was targeted toward the cloning, expression, and purification of the immunogenic regions of equine merozoite antigen 1 (EMA-1 gene), as one of the most important immunodominant surface proteins in T. equi, from naturally infected horses in Iran. The immunogenic region of EMA-1 gene was amplified using the blood of infected horses. EMA-1 gene was cloned into pET26b vector. Then, recombinant plasmids (pET 26b-EMA-1) were transformed into competent E. coli BL21 (DE3) cells. Cloning was confirmed by polymerase chain reaction (PCR), restriction enzyme assays, and DNA sequence analysis. The recombinant protein was expressed using isopropyl β-D-1-thiogalactopyranoside as an inducer, purified using nickle-nitrilotriacetic acid column, and then confirmed by 10% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and dot blot analysis utilizing Anti-His Tag antibody. Furthermore, the immunoreactivity of recombinant protein against the serum of the infected horses was evaluated using dot blot analysis. The PCR product analysis showed a 750-bp band belonging to immunogenic regions of EMA-1 gene. Sequence analysis revealed that cloned EMA-1 and protein had 94% and 97% homology to EMA-1 sequences submitted to GenBank from different countries, respectively. Restriction enzyme and sequence analyses confirmed the subcloning and correction of the orientation of inserted gene. The SDS-PAGE analysis confirmed the expression of EMA-1 protein with a 28-kDa band. The results of the dot blot analysis revealed that the horse serum containing antibody against T. equi could react with the purified recombinant protein. Purified EMA-1 protein can be used as a reliable tool for the future development of diagnostic tests or vaccines

Purtscher-like retinopathy following valsalva maneuver effect: case report

<p>Abstract</p> <p>Introduction</p> <p>Purtscher's retinopathy is a rare condition that is noted in cases related to various types of trauma. The characteristic finding in the fundus is the presence of multiple Purtscher flecken. Purtscher-like retinopathy has a similar presentation in the fundus, but without an association with trauma.</p> <p>Case presentation</p> <p>A 43-year old Malay man presented with a sudden onset of central foggy vision in the left eye after holding his breath for two minutes while catching a falling object. It was not associated with floaters, flashes of light, or head trauma. His vision in the right eye was 6/6, and in his left eye it was finger counting. He had bilateral temporal sub-conjunctival hemorrhages. An examination of his left fundus revealed multiple white cotton wool spots and dot-blot retinal hemorrhages with diffuse retinal edema at the posterior pole. His right fundus was noted to have only mild temporal peri-papillary edema associated with a few dot-blot hemorrhages. Fundus fluorescein angiography showed good arterial perfusion and no evidence of leaking or neo-vascularization. A diagnosis of Purtscher-like retinopathy was made, and the patient was treated with indomethacin tablets for six weeks. At his six-week follow-up examination, his left eye visual acuity had improved to 6/12. His bilateral sub-conjunctival hemorrhage had resolved. His left fundus showed residual multiple cotton wool spots and reduced retinal edema.</p> <p>Conclusions</p> <p>Treatment with non-steroidal anti-inflammatory drugs seems to be effective in reducing edema in patients with Purtscher-like retinopathy.</p

Circadian-Related Sleep Disorders and Sleep Medication Use in the New Zealand Blind Population: An Observational Prevalence Survey

STUDY OBJECTIVES: To determine the prevalence of self-reported circadian-related sleep disorders, sleep medication and melatonin use in the New Zealand blind population. DESIGN: A telephone survey incorporating 62 questions on sleep habits and medication together with validated questionnaires on sleep quality, chronotype and seasonality. PARTICIPANTS: PARTICIPANTS WERE GROUPED INTO: (i) 157 with reduced conscious perception of light (RLP); (ii) 156 visually impaired with no reduction in light perception (LP) matched for age, sex and socioeconomic status, and (iii) 156 matched fully-sighted controls (FS). SLEEP HABITS AND DISTURBANCES: The incidence of sleep disorders, daytime somnolence, insomnia and sleep timing problems was significantly higher in RLP and LP compared to the FS controls (p<0.001). The RLP group had the highest incidence (55%) of sleep timing problems, and 26% showed drifting sleep patterns (vs. 4% FS). Odds ratios for unconventional sleep timing were 2.41 (RLP) and 1.63 (LP) compared to FS controls. For drifting sleep patterns, they were 7.3 (RLP) and 6.0 (LP). MEDICATION USE: Zopiclone was the most frequently prescribed sleep medication. Melatonin was used by only 4% in the RLP group and 2% in the LP group. CONCLUSIONS: Extrapolations from the current study suggest that 3,000 blind and visually impaired New Zealanders may suffer from circadian-related sleep problems, and that of these, fewer than 15% have been prescribed melatonin. This may represent a therapeutic gap in the treatment of circadian-related sleep disorders in New Zealand, findings that may generalize to other countries

Changes in the Circadian Rhythm in Patients with Primary Glaucoma

Purpose The current study was undertaken to investigate whether glaucoma affects the sleep quality and whether there is any difference between patients with primary glaucoma (primary open angle glaucoma, POAG and primary angle-closure glaucoma, PACG) and healthy subjects, using a validated self-rated questionnaire, the Pittsburgh Sleep Quality Index (PSQI). Methods The sleep quality of patients with POAG and PACG was tested against normal controls. Subjects were divided into three sub-groups according to age. Differences in the frequency of sleep disturbances (PSQI score >7) were assessed. The differences of sleep quality within the three groups and within the POAG group depending on the patients’ intraocular pressure (IOP) and impairment of visual field (VF) were also studied. Results 92 POAG patients, 48 PACG patients and 199 controls were included. Sleep quality declined with age in control and POAG group (tendency chi-square, P0.05). No significant differences were found in POAG group between patients with a highest IOP in daytime and at nighttime (χ2-test, P>0.05). Conclusions The prevalence of sleep disorders was higher in patients with POAG and PACG than in controls. PACG patients seemed to have a more serious problem of sleep disorders than POAG patients between 61 to 80 years old. No correlation was found between the prevalence of sleep disorders and impairment of VF or the time when POAG patients showed a highest IOP
