Abstract
Variation of recurred branch of median nerve in relation to the median and flexor retinaculum are significant for both hand surgeons and specialists always. In this study, 64 cadaver hands (32 men) have been dissected. The median nerve was identified at the proximal edge of the flexor retinaculum, and in order to expose carpal tunnel the ligament was divided, and the above subjects were studied. The results are: 1) The relation of recurrent nerve to the flexor retinaculum was classified into 4 types: A) In (53.1%) of subjects, this branch arises from the median after the flexor retinaculum. B) In (31.3%) of subjects, it arises from the median in the carpal tunnel and the moves around the lower edge of flexor retinaculum and enters the thenar region. C) In (14.1%) of subjects, it arises from the median in the carpal tunnel and pierces the flexor retinaculum. D) In (1.56%) of subjects it arises, in the carpal tunnel and it divides into two subbranches here. One follows pattern A and the other pattern C. 2) In this step, the relation of the recurrent branch to the median nerve was studied. The results show that inspite of this image even though most often the recurrent branch arises from the lateral side of median, in (68.75%) of subjects it arises from it's anterior surface. The MC Nemar test reveals that there is no relation between manifestation of mentioned patterns with right or left hands.

Abstract
In order to evaluate the role of idiopathic hypercalciuria (IH) in causing hematuria, nephrolithiasis and recurrent urinary tract infections we studied two groups of children for idiopathic hypercalciuria. 1) Patients group: children with hematuria, nephrolithiasis and recurrent urinary tract infections (n=452). 2) Control group: children with no urinary tract problem (n=100). In control group 3% of children had IH. In patients group 27.5% of patients with hematuria, 37% of patients with nephrolithiasis and 7.9% of patients with recurrent urinary tract infections had IH, P values=0.001, 0.005 and 0.2, respectively. This study confirms that there is a positive association between IH and hematuria or nephrolithiasis, but there is no significant association between recurrent urinary tract infections and IH

Abstract
This is a morbidity study about vascular trauma in Sina hospital, from 1974 to 1999. In this study morbidity is defined as amputation, wound infection, and recurrent thrombosis.
Materials and Methods: We reviewed the Patient's records and studied the effects of different factors such as type of trauma, associated injury, absence of capillary filling and presence or absence of distal pulse before and after surgery on morbidity.
Results: Reviewing 100 cases, we found 83 percent of them were thrombosis. The mean age was 32.5 years old. From the patients, 76 percent had penetrating trauma and the reminder had blunt traumas. Type of blunt trauma, associated injury, absence of capillary filling and the status of distal pulse, before and after surgery, time of surgery, muscular response to cautery and duration of hospital stay, all were associated with morbidity (P < 0.05).
Conclusion: In this study it is concluded that prompt diagnosis of vascular injuries, primary resuscitation and transferring the patients to proper centers and appropriate care of complicated cases, will help us to reduce morbidity.

Abstract
Background: In 2-4% of couples in fertile ages, recurrent pregnancy loss (RPL) occurs which consisted one out of 300 pregnancies. The aim of this study was to comparison insulin resistance (IR) in patients with RPL to normal individuals.
Materials and Methods: In a case-controlled, prospective study, 49 non-pregnant, non-diabetic women with early RPL as the case group and 49 non-pregnant, non-diabetic women without RPL who had at least one live infant as the control group, and were matched by age, weight, and height, were enrolled. In both groups fasting insulin and glucose levels were measured and insulin resistance, which was defined as a fasting insulin (FI) level ≥20 microU/mL or a fasting glucose to insulin ratio (FGI ratio) of <4.5, was calculated.
Results: The RPL and control groups were similar with respect to age, BMI, fasting glucose levels and glucose to insulin ratios. FI was significantly higher in RPL group than control group (15.20±5.82 vs. 12.23±5.64 microU/mL). Also the frequency of patients with high FI (FI≥20µU/ml) in RPL group was significantly higher than in control group (22.45% vs. 6.12%, Odds Ratio=4.44, Confidence Interval 95%=1.15-17.07). Among the RPL group, 24.49% demonstrated insulin resistance, whereas only 8.16% of the matched controls were insulin resistant (Odds Ratio=3.65, Confidence Interval 95%=1.08-12.26). The RPL and control groups had similar in frequency of low FGI ratio. Also there was no significant difference between mean of FGI ratio in patients with fewer than 12 weeks miscarriage compared to over 12 weeks in RPL group.
Conclusion: Women with RPL have a significantly increased prevalence of insulin resistance when compared with matched fertile controls. It's recommended that in all women with RPL the glucose and insulin measurement should be carried.

Abstract
Background: Vulvovaginal candidiasis, the most common type of vaginitis, is usually caused by Candidia albicans. Patients experience a variety of symptoms. There are many types of vulvovaginal candidiasis with various microbial causes, symptoms, host circumstances, recurrence rates, and responses to treatment. The purpose of this study was to find the best method of treatment of complicated vaginitis as determined by its high prevalence, varying symptoms and signs and patient complaints.
Methods: In this open clinical trial without placebo control, we studied all patients aged 18 to 65 years, suffering from vaginitis symptoms that presented at the gynecological clinic of Arash Hospital, Tehran, Iran, during the year 2004. After obtaining informed consent, we assessed the response to a treatment of single 150 mg dose of fluconazole in one group, and sequential 150 mg doses of fluconazole in the other. The analysis was performed using SPSS statistical software (version 11).
Results: With regard to symptom severity, no significant difference was found between the groups. The rate of excoriation and fissure formation demonstrated significant difference between the two groups (p=0.048). Assessment of clinical and mycological response proved that patients with severe vaginitis treated with sequential doses of fluconazole had a better general status than those in the other group. The difference between the severity of vaginitis and positive response to the treatment in culture was not significant among patients with recurrent vaginitis.
Conclusion: Patients with mild to moderate recurrent vaginitis show better response to treatment. The high rate of positive culture on day 35 reconfirms the limitation of fluconazole and other azoles as fungistatic drugs.

Abstract
Background: Impairment in the function of the lower urinary tract can be the cause of recurrent urinary tract infections (UTI) and vesico-ureteral reflux (VUR) in children. The purpose of our research was to evaluate the frequency of occurrence of bladder instability in children with UTI.
Methods: The research involved 133 children (11 boys, 122 girls), ranging in age from seven months to 14 years. Group A consisted of 78 children with a history of recurrent UTI, while Group B included 55 children with recurrent UTI and VUR. Urodynamic tests (cystometry) were performed on all the children.
Results: Abnormal functioning of the lower urinary tract was found in 98 children (73.1%) from Group A and 41 children (78.8%) from Group B. The most common dysfunction was detrusor-sphincter dyssynergia (DSD), which was found in 54% of all subjects, 46.2% of patients in Group A and 60% of patients in Group B (p<0.05). Unstable bladder was found in 42 (33%) children with no significant difference between the two groups. In 17 children (12.6%) DSD was accompanied by bladder instability. In both groups about 20% of the children did not present with symptoms indicative of urination dysfunction, where as 80% reported various symptoms, of which the most common were constipation and urinary urgency. In half of the children from Group A and one-fourth of the children from Group B there were several co-occurring symptoms: frequency, urgency, intermittent voiding, incontinence, dribbling and retention, and constipation.
Conclusions: The most common disturbance of lower urinary tract function in these children with recurrent UTI was DSD, which occurred more often in children with VUR.

Abstract
Background: Common Variable Immunodeficiency (CVID)
is a primary immunodeficiency disease, characterized by hypogammaglobulinemia
and heterogeneous clinical manifestations. This study was performed to evaluate
the clinical and immunological features of pediatric patients with CVID.
Methods: We reviewed the records of 69 children diagnosed
under age of 16 years with CVID
(35 males and 34
females).
Results: By the year 2008, 15 patients (21%)
had died. The total follow-up period was 333
patient-years. The mean diagnostic time between onset and diagnosis in our
patient group was 4.40 years. The overall
rate of consanguineous marriages was 58%.
10 patients had a positive family history of
immunodeficiency. At the time of diagnosis, the mean levels of serum
immunoglobulin G (IgG),
IgM,
and IgA levels
were 286.86, 39.92, and 18.39
mg/dl, respectively which were below the normal levels for age. All of the
patients presented with infectious diseases at the time of onset, the most
common of which were pneumonia, diarrhea and sinusitis. Acute and recurrent
infections were also found in almost all of the patients, particularly
involving respiratory and gastrointestinal systems. The most common infections
during follow-up period were pneumonia (31.9%),
acute diarrhea (18.8%), acute sinusitis (18.8%),
and otitis media (14.5%). Post-diagnosis
survival was estimated to be 79% during the first
five years. The survival rate was not shown to be influenced by delayed
diagnosis, serum levels of IgG
and B-lymphocyte count at the time of diagnosis.
Conclusions: Any child with a history of recurrent infections, decreased levels of serum
immunoglobulin isotypes and consanguineous parents should be considered as a CVID
patient.

Background: The results indicated that the immunologic and genetic factors play a key role in the susceptibility to this syndrome compared to other risk factors. Immunoglobulin G, representing approximately 80% of Immunoglobulins in humans and the only way that IgG2 can be passed from mother to fetus blood circulation is binding to Fcgamma receptor (FcγR) classes which have been coded by Fcgamma receptor (FcγRIIA) gene. Any changes in the FcγRIIA gene structure such as mutations or polymorphisms can be considered as risk factors on the incidence of abortion through causing the inflammation or decreasing fetus safety. This receptor is the only which can have an interaction with IgG2 antibody and the Therefore, the current study was carried out to assess the association between R/H131 polymorphism in the FcγRIIA gene and susceptibility to recurrent abortions in Iranian women.
Methods: For this reason, a case-control study was confirmed to compare the frequency of FCGR2A gene R/H131 polymorphism in 150 women with recurrent miscarriage history having normal karyotype and 150 healthy women with no abortion history as control which were collected in March 2014 up to September 2015, from Royan Institute for Reproductive, Tehran, Iran. The genomic DNA was extracted from peripheral blood leukocytes and genotyping was performed using amplification refractory mutation system-polymerase chain reaction (ARMS-PCR).
Results: The frequency of AA, AG, and GG genotypes in case and control groups were 31.3%, 54.7%, 14% and 27.3%, 49.2%, 23.5% respectively. According to the findings, the presence of the risk allele was not associated with increased risk of recurrent miscarriage compared with individuals lacking the risk allele and it statistically was significant (P= 0.11). No significant association was found between the age of participants and risk of abortion in Iranian studied population (P= 0.083).
Conclusion: The results of present study do not support the previous findings of an association between R/H131 polymorphism in FCGR2A gene and recurrent miscarriage.

Abstract
Background: Recurrent pregnancy loss is a form of infertility with at least three consecutive pregnancy losses or more. Y chromosome microdeletions are a class of most likely genetic factors that occur in a special zone of Y chromosome which is named azoospermia factor region. The purpose of this study was to analyze the presence of Y chromosome complete microdeletions in male partner of couples suffering from idiopathic recurrent pregnancy loss among Iranian population.
Methods: In the present study, Y chromosome microdeletions were evaluated in ninety-two male partners of couples with the experience of recurrent pregnancy loss as the patient group and also a group containing fifty fertile males as the control group. The research has done in Medical Genetic laboratory of Tehran and Islamic Azad University Science and Research Branch, Tehran, Iran within June 2013 to September 2014. The selected sequence tagged site markers (primers) including sY84, sY86, for azoospermia factor a; sY127, sY134, sY129, for azoospermia factor b and sY254, sY255, for azoospermia factor c were used to screen complete microdeletions in Y chromosome. At the first step DNA samples were extracted from all men’s peripheral blood in both patient and control groups and then multiplex polymerase chain reaction and also agarose gel electrophoresis were performed on this DNA samples so as to detect deletions.
Results: With due attention to the data resulted from multiplex polymerase chain reaction and agarose gel electrophoresis in order to recognize Y chromosome micro deletions in azoospermia factor region, in this work, all the bands related to the mentioned primers which were formed during the polymerase chain reaction, were detected on the gel obviously. It means that none of the samples neither the fifty fertile men nor the ninety-two patient men had complete micro deletions in their Y chromosome.
Conclusion: This study suggests that there is no correlation between Y chromosome micro deletions and occurrence of recurrent pregnancy loss in Iranian population.
