Introduction:
Obesity is strongly associated with coronary heart disease and it is known as an independent risk factor. So, the aim of this study was to investigate the effects of phase II comprehensive cardiac rehabilitation program on obesity indexes, functional capacity, lipid profiles, and fasting blood sugar in obese and non-obese female patients with coronary heart disease and to compare changes in these groups.
Materials and Methods:
Two hundred and five women with coronary heart disease participated in our study. At the beginning of study, body mass index, functional capacity, and lipid profiles and fasting blood sugar were evaluated; then, these patients were divided into two groups, patients who had BMI≥30 were known as obese and who had BMI<30 were known as non-obese patients. All of them completed the period of cardiac rehabilitation program, and 2 months later, all risk factors were examined for the second time in each group. Data were analyzed with SPSS software version 15. For comparing the mean of outcomes, independent
t
-tests and paired
t
-tests were used.
Results:
Data revealed that unless in weight (
P
=0.00) and functional capacity (P=0.001), there were no significant differences in obese and non-obese female patients, at baseline. As a result of the cardiac rehabilitation program, both groups had significant improvement in functional capacity (
P
=0.00), weight reduction (
P
=0.00), triglyceride (
P
=0.01 and
P
=0.02, respectively), low-density lipoprotein cholesterol (
P
=0.01), and low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (P=0.00 and
P
=0.003, respectively). As well, significant improvement was observed in high-density lipoprotein (
P
=0.01) only in obese female, and non-obese female had significant differences in total cholesterol (
P
=0.003). However, there were not significant changes in total cholesterol (
P
=0.05) and fasting blood sugar (
P
=0.09) in obese female. Also, non-obese females didn't have favorable differences in high-density lipoprotein cholesterol (
P
=0.23) and fasting blood sugar (
P
=0.13). In addition, comparing two groups didn't show any significant differences in each risk factors except BMI (
P
=0.03).
Conclusion:
Our study revealed that comprehensive cardiac rehabilitation program results in significant improvement in cardiovascular risk factors and functional capacity at all levels of BMI in female with coronary heart disease.

Leeches are blood-sucking hermaphroditic parasites that attach to vertebrate hosts, bite through the skin, and suck out blood. When leeches feed, they secrete an anticoagulant (hirudin), which helps them get a full meal of blood. This is the first report of leech removal from external auditory canal. Previous leech involvement cases were explained in nasopharynx, larynx, pharynx, eye, and gastrointestinal tract. Prominent sign of all cases was active bleeding from the leech attachment site; that stopped with leech removal. A 24-year-old man was presented to Al-Zahra hospital with left otorrhagia and otalgia from 2 days ago. After suction of ear a small soft foreign body was seen in the external ear near the tympanic membrane, then the ear filled with glycerine phenice, the patient explained decreased movement of foreign body. Four hours later the bloody discharge stopped and otalgia decreased. After suction of clots, a leech was extruded from external auditory canal by alligator. Leech infestation is a rare cause of otorrhagia and should be suspected in the endemic region in all of unusual bleeding; it can be diagnosed and treated by exact inspection and removal.

Developmental stuttering is a common disorder of speech dissiliency that is characterized by excessive repetitions of sounds, syllables, and monosyllabic words, as well as sound prolongations and complete blockages of the vocal tract. About 60 million people are affected and it is more common between the age of 3 and 6, when children begin forming sentences and connecting thoughts verbally. There are three types of stuttering known as developmental stuttering, neurogenic stuttering, and psychogenic stuttering. The exact pathophysiology of developmental stuttering is unknown; however, various family and twin studies have repeatedly implicated heredity as a major factor in the etiology of stuttering. It is clear that the genetic influence is not in the form of an exact single gene effect such as autosomal recessive, autosomal dominant, or x-linked in all families; however, in all of the inheritance forms it is influenced by sex with higher occurrence in males than females at a ratio of 4:1 in older children and adults. Recently special genetic locus has been determined on several autosomal chromosomes related to developmental stuttering. In this report, the proband is a 20-year-old boy was referred to our clinic for premarriage genetic counseling; he has been affected since 3 years and now is under cure. three generation study of his family show 13 individuals are affected by stuttering. For the first it occurred in the proband's grandfather and after this time about all of affected cases has been seen in consanguineous marriages. Therefore, the genetical inheritance of stuttering is crystal clear in this family and autosomal recessive inheritance pattern is proposed. Totally in such families with repeated occur of stuttering, we cannot account it as a multifactorial disorder.

PMID
:23210072
Background:
Carpal tunnel Syndrome (CTS) is the most common compression neuropathy. Jobs with frequent and repetitive hand movements are one of the risk factors for this syndrome. The aim of this study was to determine the prevalence of CTS in Isfahanian dentists.
Materials and Methods:
In this cross-sectional descriptive study, 240 dentists were evaluated for CTS. Diagnosis was made according to both questionnaire and clinical tests of Phalen and Tinel. Age, sex, years of experience, working hours per week and the type of procedure were considered as dependent variables. All data were analyzed by Chi-square and
T
-test using SPSS software 11.5 (α=0.05).
Results:
Among the dentists who were studied, 173 (72%) were male and 67 (28%) were female. 16.2% of males and 17.9% of females had symptoms of CTS and there wasn't any significant difference between them (
P
>0.05%). the prevalence increased with advancing age. In a way that it reached to 22.2% in ages more than 55 in contrast to 6% among individuals between 25-34 years old. With increasing of experience to 15 years the risk of CTS increased but an unexpected reduction was observed with more than 15 years of experience.
Conclusion:
This study showed the prevalence of CTS was 16.7% among dentists and was more common in older dentists. CTS prevalence was increased with age. The dentist population with more working hours per week and more experience years were more susceptible for this syndrome. Using suitable gloves, wrist splints and short periods of resting during vigorous continuous working can decrease the symptoms of this disease.

Efficient transdifferentiation of human adipose-derived stem cells into Schwann-like cells: A promise for treatment of demyelinating diseases
Shanhaz Razavi, Nafiseh Ahmadi, Mohammad Kazemi, Mohammad Mardani, Ebrahim Esfandiari
Adv Biomed Res
2012, 1:12 (11 May 2012)
DOI
:10.4103/2277-9175.96067
PMID
:23210071
Background:
Schwann cells (SCs) can provide a suitable option for treatment not only diseases of peripheral nervous system (PNS), but also diseases of central nervous system (CNS). It is difficult to obtain sufficient large number of SCs for clinical purpose because of their restricted mitotic activity, and by sacrificing one or more functioning nerves with the consequence of loss of sensation. So, providing an alternative source for transplantation is desired. The aim of this study was isolation, characterization of human adipose derived stem cells (ADSCs), and transdifferentiation into Schwann-cells.
Materials and Methods:
After isolation of ADSCs by mechanical and enzymatic digestion of adipose samples, characterization human ADSCs using flow cytometry was carried out. Human ADSCs were sequentially treated with various factors for neurosphere formation and terminal differentiation into Schwann-like cells. We used Schwann cell markers, GFAP and S100 to confirm the effectiveness of the differentiation of human ADSCs using Immunostaining and real time RT-PCR techniques.
Results:
Flow cytometry analysis of ADSC showed isolated stem cells were positive for CD90 and CD44 markers of mesenchymal stem cells, but for CD45 and CD34 markers were negative. Dual immunofluorescence staining and real time RT-PCR analysis for GFAP and S100 markers were revealed that approximately 90% of differentiated cells expressed co-markers.
Conclusion:
We indicated that human ADSCs have a suitable option to induce Schwann-like cells for autologous transplantation, offer promise for treatment in demyelinating diseases.

Adv Biomed Res
2012, 1:11 (11 May 2012)
DOI
:10.4103/2277-9175.96064
PMID
:23210070
Background:
The aim of this study was measurement of the radiation doses received by patients for common radiology examinations in hospitals under control of Isfahan University of Medical Sciences, Iran.
Materials and Methods:
Thermoluminescence (lithium fluoride chips, LiF: Mg, Tl) dosimeter was used to measure patient dose for four (chest, posterior-anterior and lateral and skull anterior-posterior, or posterior-anterior and lateral) common radiographic views in six hospitals (seven X-ray machines). The entrance surface dose was measured on 20 randomly patients for each X-ray room.
Results:
The maximum (8.85 ± 0.62 mGy) and the minimum (0.62 ± 0.22 mGy) values of ESD was obtained for X-ray machines of Shimadzu and Varian located in Ashrafi-Khomeini-shahr and Kashani hospitals, respectively. As results shows, the values of ESD of skull were higher than that of chest examinations.
Conclusion:
The results of this study indicated that ESD measured doses were slightly greater than the ICRP and NRPB reference doses. Efforts should be made to further lower patient doses while securing image quality. In addition, the need to provide relevant education and training to staff in the radiology sections is of utmost importance.

Original Article:
Predicting efficiency of post-induction mask ventilation based on demographic and anatomical factors
Mahmoud Saghaei, Hamid Shetabi, Mohammad Golparvar
Adv Biomed Res
2012, 1:10 (11 May 2012)
DOI
:10.4103/2277-9175.96056
PMID
:23210069
Background:
Failure to ventilate patients by mask leads to serious complications especially if associated with difficult intubation. Previous studies have used subjective and indirect measures to evaluate difficulty in mask ventilation, which are associated with high inter-observer discrepancies. In this study, we have defined and used efficiency of mask ventilation (EMV) as an objective and direct surrogate for ease of mask ventilation in patients undergoing GA and mask ventilation using neuromuscular relaxation.
Materials and Methods:
1050 adult patients prospectively were evaluated with respect to different patients demographic and physical factors and EMV. EMV was defined as the ratio of minute ventilation via anesthesia mask to that via tracheal tube expressed as percentage. Edentolous patients were ventilated using lip-over-mask techniques. Separate analyses were done for edentolous and non-edentolous patients.
Results:
EMV in edentolous patients (
n
=269) using the lip-over-mask method was relatively high (90.9 ± 14.3%, 60.14-128.57 range). The result of multiple regression analysis in patients with normal denture determined receded chin, presence of beard, male gender, high Mallampati classes, high neck circumference, low inter-incisors gap, and old age as independent factors for estimating EMV. A regression formula for predicting EMV was developed which had an acceptable R-square value with a good model fit.
Conclusions:
Using EMV is an easy and reliable tool for measuring efficiency of mask ventilation. Based on the result of this study, EMV can be estimated from patient's demographic and physical factors. In edentolous patients, using the lip-over-mask method results in adequate ventilation of lungs.

Comparing the preventive effect of midazolam and midazolam-dexamethasone on postoperative nausea and vomiting in elective middle ear surgery
Sayed Morteza Heidari, Reihanak Talakoub, Zahra Yaraghi
Adv Biomed Res
2012, 1:9 (11 May 2012)
DOI
:10.4103/2277-9175.96052
PMID
:23210068
Background:
Nausea and vomiting are common postoperative complications with incidence of 20-80% depends on the surgery type, anesthetic drugs, age, sex, etc. This complication may lead to patient discomfort, intraocular, and intracerebral pressures increase, sutures rupture, esophageal injury, and rarely death. Many studies reported that midazolam and dexamethasone alone can decrease postoperative nausea and vomiting (PONV), but their combination has never been studied yet. The aim of this study was to compare the effect of midazolam and midazolam-dexamethasone on PONV after middle ear surgery.
Materials and Methods:
66 ASA I and II patients aged 15-65 year scheduled for elective middle ear surgery under general anesthesia randomly divided into two groups. Immediately after induction of the anesthesia group one (M) received midazolam 0.075 mg/kg and group two (M+D) received combination of midazolam (0.075 mg/kg) plus dexamethasone (0.05 mg/kg). Then the severity of nausea was measured by visual analog scales 0-10 (VAS) in recovery room at 6, 12, and 24 h after surgery. Metoclopramid (0.1 mg/kg) was administrated I.V. slowly if nausea score was above 3 or patient had vomiting. The postoperative need for antiemetics and the duration of stay in recovery room were recorded. Values of
P
<0.05 were considered statistically significant.
Results:
There were no significant differences in age, gender, and weight between the two groups. There was no significant difference in the mean nausea scores between two groups except after 12 h postoperatively (1.39 ± 3.19 in M group vs. 0.42 ± 1.71 in M+D group). The mean vomiting frequency was significantly less in midazolam-dexamethasone group in the recovery room (0.9 ± 0.29 vs. 0 ± 0) and at 6-12 h (1.09 ± 2.41 vs. 0.3 ± 0.8), and 12-24 h (0.42 ± 1.32 vs. 0.03 ± 0.17) postoperatively. During the first 24 h postoperatively, the metoclopramid consumption was significantly less in combination therapy (6.48 ± 9.54) than in the midazolam group (12.9 ± 23.44) (Value<0.5).
Conclusion:
The combination of midazolam-dexametazone is more effective than midazolam alone in prevention of postoperative vomiting after middle ear surgery. Therefore, we recommend combination therapy for patients who are prone to PONV.

Adding different doses of intrathecal magnesium sulfate for spinal anesthesia in the cesarean section: A prospective double blind randomized trial
Mitra Jabalameli, Seyed Hamid Pakzadmoghadam
Adv Biomed Res
2012, 1:7 (11 May 2012)
DOI
:10.4103/2277-9175.94430
PMID
:23210066
Background:
There is uncertainty as to whether addition of magnesium sulfate to spinal local anesthetics improves quality and duration of block in the caesarean section. In this randomized double blind clinical trial study, we investigated the effect of adding different doses of intrathecal magnesium sulfate to bupivacaine in the caesarean section.
Materials and Methods:
After institutional approval and obtaining informed patient consent, 132 ASA physical status I-II women undergoing elective cesarean section with spinal anesthesia were randomized to four groups: 1−2.5 cc Bupivacaine 0.5%+ 0.2 cc normal saline (group C) 2− 2.5 cc Bupivacaine 0.5%+ 0.1 cc normal saline+ 0.1 cc magnesium sulfate 50% (group M
50
) 3− 2.5 cc Bupivacaine 0.5%+ 0.05 cc normal saline+ 0.15 cc magnesium sulfate 50% (group M
75
) 4− 2.5 cc Bupivacaine 0.5%+ 0.2 cc magnesium sulfate 50% (group M
100
). Patients and staff involved in data collections were unaware of the patient group assignment. We recorded the following: onset and duration of block, time to complete motor block recovery, and analgesic requirement.
Results:
Magnesium sulfate caused a delay in the onset of both sensory and motor blockade. The duration of sensory and motor block were longer in M
75
and M
100
groups than group C (
P
< 0.001). Recovery time was shorter in group C (
P
< 0.001) and analgesic requirement was more in group C than others (
P
< 0.001).
Conclusions:
In patients undergoing the caesarean section under hyperbaric bupivacaine spinal anesthesia, the addition of 50, 75, or 100 mg magnesium sulfate provides safe and effective anesthesia, but 75 mg of this drug was enough to lead a significant delay in the onset of both sensory and motor blockade, and prolonged the duration of sensory and motor blockade, without increasing major side effects.
