Between 1990-97 two hundered children referred to our department with end-stage renal disease (ESRD) for renal replacement therapy. The ages of these children were 1-14 years (mean 8.14). There was no significant difference in incidence of ESRD between two sexes. We evaluated these children for the causes of ESRD. The most common causes were: Pylonephritis and congenital anomalies of urinary tract (35.5%), glomerular diseases (22.5%) and hereditary kidney diseases (13.5%).

Background: Cyclosporin A (CsA) is now commonly used in the management of children with steroid-dependent and steroid resistant nephoitic syndrome. It has been reported to be effective in maintaining remission in 70-100 percent of patients with SDNS but somewhat SRNS 0-100 percent. The aim of this study was to evaluate the efficacy of long-term (CsA) in children with refractory nephrotic syndrome (RNS) and steroid dependent nephrotic syndrome (SDNS).
Materials and Methods: The long-term effect of (CsA) in 91 Iranian children aged 3 months to 11 years (54 with RNS and 37 with SDNS) was assessed between 1984 and 1999. Eighty of 91 children received renal biopsy prior to introduction of (CsA), and the other 11 patients had not consent for kidney biopsy. If the patients did not show remission aftre receiving 3-6 months of (CsA), the medication was discontinued.
Results: All patient were treated with (CsA) in combination with low dose alternate day prednisolone. In children with RNS and SDNS, therapy with (CsA) induced, remission in 25 of 54 (46.2 percent) and 27 of 37 (73 percent) respectively (P<0.02). Of the 32 patients with minimal change disease (MCD), 23 (72 percent) responded to therapy, compared with 4 of 18 (22 percent) with focal segmental glomerulosclerosis (FSGS) (P<0.005). Twenty-four (48 percent) of 50 who entered complete remission, had relapse 1-12 months after cessation of (CsA). The duration between the onset of nephrotic syndrome (NS) and administration of (CsA) and sexuality of patients had no effect in result of treatment. Side effects occurred in 25 patients (27.4 percent). No patients exhibited raised transaminases, 8 (8.7 percent) of the children developed hirsutism, 7 (7.6 percent) hypertension, 7 (7.6 percent) gingival hyperplasia, (2.2 percent) neurological toxicity and 1 (1 percent) increase in serum creatinine.
Conclusion: Our findings suggest that (CsA) can be used to induce a complete remission in a significant proportion of patients with RNS and SDNS, and patients with SDNS have areasonable potential for remission than children with RNS. Resistant to steroid and cyclophosphamid.

Background: Chronic renal failure defines as progressive and irreversible dysfunction of kidneys that could eventually terminated to end stage renal disease (GFR< 10% NL). Because of therapeutic problem and high mortality and morbidity and it &aposs implication quality of life , ESRD is one of the important dilemma of pediatric medicine .
Materials and Methods: In our study 216 patients evaluated .
Results: Male to female ratio was 1.1 . The peak of the presenting age of ESRD was 10 years old (8-12 y). Congenital urological malformation (30%) , glomerulopathies (20%) , hereditary nephropathies (14.3%) , multisystem diseases (7%) and nephrolithiasis (6.2%) are the most common etiologies of ESRD . VUR in 21% and congenital obstructive disease in 8.5% are the etiology of ESRD. In patients with age five years old and lesser common causes of ESRD are congenital urologic malformation and glomerulopathies. In other age groups , urologic malformation is the most common cause of ESRD. In etiologic assessment of two separate 7 years interval , (1988-1993) and (1996-2003) , there was not any significant change in frequency of etiologies but frequency of congenital obstructive uropathy decreased from 10 % to 5.7%. Total amount of VUR (VUR ± Neuropathic bladder) has not any change but frequency of primary reflux nephropathy decreased from 14.2% to 8%. In this study , in 145 patients hemodialysis continued and 28 cases had unsuccessful renal transplant (13.8%) . 7.4 % of patients had successful renal replacement therapy (RRT) and mortality rate was 7.4% . B
Conclusion: Based on that the most common cause of ESRD is all ages in congenital urologic malformations , early diagnosis and appropriate management of these cases are effective in decreasing incidence of ESRD and with respect to few cases of renal transplant and unsuccessful results in 65% of RRT , the approach of this problem should be revised.

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.

Background: We evaluated the efficacy of botulinum-A toxin (BTX-A) injection into detrusor muscle in patients with incontinence resistant to anticholinergic drugs due to detrusor overactivity.
Methods: Our prospective study included 12 male patients with detrusor overactivity and incontinence due to spinal cord injury, which had been unsuccessfully treated with anticholinergic medication. Under visual control through the cystoscope 300 units of BTX-A were injected into detrusor muscle at 30 sites, sparing the trigone. After the treatment patients continued to perform clean intermittent self-catheterization (CIC) and clinical follow-up was planned for 6 weeks, 6 months and 9 months after treatment and urodynamic study was repeated after 6 weeks.
Results: At the 6-week follow-up complete continence was restored in 9 of the 12 patients and after 6 months of 9 continent patients 1 patient lost his follow-up from the study and 7 were still continent. After 9 months 3 patients remained continent. Mean cystometric bladder capacity (p<0.001), compliance (p<0.001), and mean post-void residual urine volume significantly increased (p<0.001), whereas maximal detrusor contraction pressure significantly decreased (p<0.001).
Conclusions: BTX-A injections appears to be an effective and safe therapeutic option for overactive bladder in adult patients with spinal cord injury failing anticholinergic therapy even if these patients present with very low bladder compliance. Patients may require repeated injections after 6 months to remain continent.

Background: Nephrotic syndrome is one of the most remarkable diseases in childhood. The majority of patients have prompt response to corticosteroids.
Methods: In this study, we retrospectively evaluate the outcome of patients with steroid-responsive nephritic syndrome. Medical records from January 1996 to September 2006 were reviewed to identify all children with steroid sensitive nephrotic syndrome at the Pediatric Medical Center, Tehran, Iran. Initial steroid therapy was 60 mg/m2 per day for four weeks. Levamisole, a steroid-sparing agent, was prescribed at a dose of 2.5 mg/kg on alternate days in conjunction with alternate-day prednisolone. If no benefit was observed by three months, levamisole was discontinued and immunosuppressive therapy with cyclophosphamide at a dose of 3 mg/kg daily for 8 weeks, or cyclosporin A at a dose of 3-5 mg/kg was prescribed.
Result: Of 745 children with steroid sensitive nephrotic syndrome, 63.1% of patients were male. The most common causes were minimal change disease (98/324, 30.2%) and focal segmental glomerulosclerosis (81/324, 25%). At presentation, microscopic hematuria was found in 22.6% of the patients. During follow-up, 9.2% had no relapse at any time, while 15.8% were frequent relapsers. The remission period ranged from 3.5 to 168 months. At the last follow-up, 57.6% of the patients were in remission, 37.7% relapsed and 29 children developed chronic renal failure. The outcome of nephrotic syndrome was not associated with age or gender. The end clinical status of patients correlated with duration of remission, number of subsequent relapses and response to cytotoxic agents.
Conclusions: Steroid-responsive nephrotic syndrome in children should be followed over a long period, especially patients with early relapse. Relapse was seen in more than 90% of patients. Documentation of histopathology by renal biopsy may be helpful to identify those at increased risk for a poor outcome.

Background: Childhood nephrotic syndrome is frequently characterized by a relapsing course. Due to their adverse effects, the use of corticosteroids for the management of frequently relapsing nephrotic syndrome is limited. Levamisole, a steroid sparing agent, has been found to have low toxicity. This study was conducted to evaluate the efficacy of levamisole in steroid-sensitive nephrotic syndrome (SDNS).
Methods: In this retrospective study from January 1988 to September 2006, we included data from 305 pediatric SDNS patients at the Children's Medical Center clinics in Tehran, Iran. Nephrotic syndrome was diagnosed using classic criteria. None of the patients had any signs or symptoms of secondary causes of nephrotic syndrome. All had received prednisolone 60 mg/m2/day. After remission, prednisolone administration was reduced to every other day and the steroid was tapered over the next three months. With every recurrence, prednisolone was prescribed with the same dosage, but after remission it was continued at a lower dosage for another six months or longer if there was risk of recurrence. Levamisole was administered to all patients at a dose of 2 mg/kg every other day.
Results: Patients ranged in age from 1 to 20 years (mean±SD: 4.84 ±3.1) and 70.8% were male. At the last follow up, 84 (27.5%) were in remission, while 220 (72.1%) patients had relapsed or needed a low dose of steroid. Levamisole was effective in reducing the prednisolone dosage and long-term remission in 68 (22.3%) and 90 (29.5%) cases, respectively. A comparison of before vs. after levamisole treatment revealed a had significant decrease in the number of relapses (2.05±0.88 vs. 1.1±1.23 P<0.0001) and the prednisolone dosage (0.74±0.39 vs. 0.32±0.38 mg/kg/day P<0.0001). Only one patient developed levamisole-induced neutropenia.
Conclusions: In childhood steroid-dependent nephrotic syndrome, levamisole is an efficacious, safe initial therapy in maintaining remission while decreasing steroid dose, in addition to reducing the rate of relapse.

Background: Nucleus accumbens (NAc) and prefrontal cortex (PFC) dopaminergic and glutamatergic systems are involved in regulating of locomotor activity behaviors. This study has investigated the interaction of NAc shell dopaminergic system and prelimbic glutamatergic systems in regulating locomotor activity and related parameters.
Methods: The aim of this study was the effect the drugs injection interaction in the brain of male Wistar rats on locomotor activity and related parameters, in the order of this purpose, open field apparatus that automatically recorded locomotor activity was employed. Unilateral intra-cerebral injection of drugs was done.
Results: Unilateral intra-prelimbic injection of D-AP7 (N-methyl-D-aspartic acid= NMDA receptor antagonist 0.25, 0.5 and 1μg/μl) did not alter locomotor activity behaviors. However, infusion of NMDA (0.9μg/μl) in this region increased locomotor activity (P<0.01), whereas decreased rearing (P<0.01) and grooming (P<0.01) which was blocked by D-AP7 (0.25μg/μl) (P<0.01). Moreover, unilateral infusion of SCH23390 (dopamine D1 receptor antagonist 0.25, 0.5 and 1μg/μl) into the left NAc shell did not alter locomotor activity. However, injection of SKF38393 (dopamine D1 receptor agonist 4μg/μl) into the left NAc shell increased locomotor activity (P<0.05) which was blocked by SCH23390 (0.25μg/μl) (P<0.01). Furthermore, the subthreshold dose infusion of SCH23390 (0.25μg/μl) into the left NAc shell reduced the effect of intra- prelimbic NMDA on locomotor activity (P<0.01). In addition, intra-NAc shell administration of the subthreshold dose of SKF38393 (1μg/μl) potentiated the middle dose (P<0.05), whereas decreased the higher dose of intra-left prelimbic NMDA response (P<0.05) on locomotor activity.
Conclusion: The results suggested a modulatory effect of the NAc shell dopaminergic system on increased locomotor activity by activating glutamate system in prelimbic.

Background: Nano scale dendrimers are macromolecules synthetic which frequently used in medical and health field. Because traditional antibiotics inevitably induce bacterial resistance, which is responsible for many treatment failures, there is an urgent need to develop novel antibiotic drugs. This study was aimed to examine Synthesis and the antibacterial effect of NanoPolyamidoamine-G7 (NPAMAM-G7) dendrimer on Escherichia Coli, Proteus Mirabilis, Salmonella Typhi, Bacillus Subtilis and Staphylococcus Aureus.
Methods: In this experimental study that has been conducted in June 2015 in the Laboratory of Microbiology, Iran University of Medical Science, NPAMAM-G7 dendrimers was synthesized by Tomalia’s divergent growth approach. The antibacterial effects of NPAMAM-G7 dendrimer were studied by disc diffusion and micro-dilution method. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against gram-positive and gram-negative bacteria were determined according to Clinical and Laboratory Standards Institute (CLSI) guideline. Standard discs were prepared using different concentrations of dendrimer on Mueller-Hinton agar plates.
Results: Zone of inhibition in concentration 25 μg/ml of NPAMAM-G7 dendrimers for Escherichia Coli, Proteus Mirabilis, Salmonella Typhi, Bacillus Subtilis and Staphylococcus Aureus were 26, 38, 36, 22 and 25 mm, respectively. Regarding the zone of inhibition in gram negative bacteria with gram positive ones was P= 0.16 and was not significant difference. The MIC for Salmonella Typhi was 0.025, for Proteus Mirabilis, Bacillus Subtilis, Staphylococcus Aureus and Escherichia Coli was 0.25 μg/ml. The MBC for Salmonella Typhi was 25μg/ml, for Proteus Mirabilis and Bacillus Subtilis was 50 μg/ml and for Escherichia Coli and Staphylococcus Aureus was 100 μg/ml. The least of sensitivity against NPAMAM-G7 related to Escherichia Coli and Staphylococcus Aureus and the most of sensitivity related to Salmonella Typhi.
Conclusion: The NPAMAM-G7 dendrimer with end amine groups exhibited a positive impact on the removal of standard strains, gram-positive and gram-negative bacteria. Therefore, it is possible to use these nanodendrimers as antibacterial in the future.

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. |

Background: Small molecule Purmorphamin (PMA) is the agonist of smoothened protein in Sonic hedgehog (Shh) signaling pathway. Effect of purmorphamin small molecule on differentiation of mesenchymal cells into bone tissue has been studied previously. Use of Shh causes progression of neural differentiation, and the differentiated cells express specific neural markers. Neurofilament (NF) and acetylcholine esterase (Chat) are specific markers of motor neurons and their expression in differentiated cells indicates their conversion into motor neurons. The aim of this study was to evaluate the ability of PMA to differentiate the human endometrial stem cells (hEnSCs) into motor neurons.
Methods: This analytical study was done in Tehran University of Medical Sciences laboratory on September of 2015. In this study hEnSCs were enzymatically extracted from endometrial tissue. After third passages, the flow cytometry was done for mesenchymal stem cells markers. The mesenchymal stem cells were divided into control and differentiated groups. FBS 10%+DMEM/F12 was added to the culture medium of control group and the differentiating group was treated with differentiating medium containing N2, PMA, DMEM/F12, FBS, B27, IBMX, 2ME, FGF2, RA, BDNF. After 21 days immunocytochemistry (ICC) test was done for the expression of NF and Chat proteins and Real-time PCR analysis for expression of neural markers such as NF, Chat, Nestin and GFAP (as glial marker) at mRNA level.
|
Results: The flow cytometry analysis showed that hEnSCs were positive for mesenchymal markers CD90, CD105 and CD146 and negative for endothelial marker CD31, and hematopoietic marker CD34. The immunocytochemistry and Real time-PCR results showed that the cells treated with PMA expressed motor neuron markers of NF and Chat. Conclusion: According to the results of this study, it can be concluded that small molecule PMA has the potency to induce the differentiation of hEnSCs into neural cells, specifically motor neurons by activating Shh signaling pathway. |

Background: Electrolysis is an electrochemical method for the treatment of water. recently water disinfection by electrochemical methods has been increasingly carried out. The aim of this applied research was to investigate the removal of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) bacteria from drinking water by using electrolysis method with Al-Fe electrodes parallel with the monopole mode.
Methods: An experimental study was conducted in the laboratory of microbiology, Iran University of Medical Science in May 2017. In this study, the contaminated water samples were prepared through adding 103, 104 and 105 E. coli and S. aureus bacteria per 1 milliliters (mL) of drinking water. Independent variables Included: different concentrations of E.coli and S. aureus bacteria (103, 104 and 105 CFU/ml), reaction time (5, 10, 15, 20 and 25 min), initial pH (7, 8 and 9), electrode gap (1, 2 and 3 cm), current density (0.83, 1.67 and 3.3 mA/cm2) to determine the optimum conditions were investigated. One-way ANOVA was used to analyze the results.
|
Results: The results show that in the optimum conditions with increasing the pH from 7 to 9 removal efficiency of bacterial strains of E. coli and S. aureus were decreased significantly from 98 to 73% and 99.1 to 76%, respectively. In initial concentration of 104 CFU/ml, optimum conditions were obtained for current density, reaction time and electrodes gap, 1.67 mA/cm2, 20 min and 2 cm, respectively. With increasing current density and reaction time in both strains of bacteria, were decreased significantly. The electrodes gap do not have much impact on the efficiency of the process. The amount of electrical energy consumed in optimal conditions was calculated 0.5128 kilowatt-hour (kWh/h). Statistical analysis shows that exist significant relationship (P<0.01) between initial concentrations of bacterial strains and efficiency of the process. Conclusion: According to the results, E. coli and S. aureus, removal efficiency were obtained more than 98%, therefore electrolysis process can be used in the removal of pathogenic bacteria from drinking water. |

Methods: This study was a double-blind clinical trial that was performed on patients with moderate to severe lumbar disc pain (VAS score or Visual analog scale more than 4) in August 2019 at Shohada Tajrish hospital. Patients in the Ibuprofen-Apotel group (group A) recieved intravenous Ibuprofen (800 mg) in 100 cc Normal saline in the first 30 minutes of Recovery, then 400 mg in 100 cc Normal saline every 6 hours (48 hours after surgery), plus 30 mg Apotel for each kilogram in100 cc Normal saline in 15 minutes every 8 hours. In group B, Morphine has injected with 70 µg/kg bolus and then 20µg/kg/h infused with a PCA pump with a Maximum Rate of 1mg/hr. Then 60 minutes after surgery, patients' pain was measured using an analog scale.
The primary outcome was defined as a reduction in pain intensity of 3 or more VAS units (which was considered as therapeutic success) and the incidence of side effects was considered as secondary outcomes.
Results: Based on the results of this study, the mean age of the subjects was 33.28±12.48 years. Also, the mean age in the group of Ibuprofen-Apotel and Morphine alone were 35.4±13.6 and 31.16±11.75 years. So, there is not a significant difference between the groups. 77.14% of the subjects (54 people) were male and 22.86% (16 people) were women. In comparing the frequency distribution of individuals in terms of gender and the method of creating analgesia, no significant difference was observed between the groups studied.
According to the results, after the intervention, the highest pain intensity in both groups was significantly decreased. However, no significant difference was observed between the two groups.
Conclusion: The study indicated that Ibuprofen can be effective in controlling postoperative pain.

Methods: This retrospective descriptive-analytical study was conducted based on case review. The statistical population included the files of patients hospitalized in the burn wards and burn intensive care unit of Zare'e Sari Burn and Psychiatric Center from 2011 to 2023 who died. All these patients were included in the study as a census. The data was extracted through a checklist prepared by the researcher. Descriptive and inferential analysis of the data was performed using SPSS version 21 software. The variables studied included gender, age, burn percentage, burn factor, and duration of hospitalization, and determining the relationship between burn percentage and survival time in the two burn intensive care units and the isolation room of the burn unit was the main variable. The mean and standard deviation were used to describe quantitative data, and the frequency and percentage were used to describe qualitative data.
|
Results: Among 882 cases, 226 patients had burns above 90%. 143 cases were related to men (63.3%). Most patients were in the age group of 19 to 40 years (61.9%). The cause of the burn (54.9%) was flame. Among the patients (83.2%) were hospitalized in the isolation room of the burn ward. Although the average days of hospitalization of patients above 90% in the burn intensive care unit was 13.71±11.82 days and the burn isolation room was 8.66±9.11 days, the Mann-Whitney test showed that the average survival time of these patients in the burn isolation room of the burn ward was significantly different from the intensive care unit. (sig.=0.001).
Conclusion: Although the average survival time in the two groups showed a significant difference, ultimately all patients in the two groups died within a few days of each other. |

Methods: This study was conducted with two methods based on the results and calculations obtained from the annual Quality Control (QC) reports and the Data Collection (DC) method related to patient scans. In this study, by referring to the annual reports of each device and using radiation components during dosimetry and determining CTDIair or CTDIw, the correction factor was obtained. Using this factor and existing equations, DLP and CTDIvol were calculated based on quality control standards. The second quartile or the median was determined as DRL for head, sinus, chest and abdomen/pelvis imaging protocols and its values were compared with each other and other studies. This study was conducted in February and March 2023 in three hospitals in Saveh city.
Results: The diagnostic reference levels of CTDIvol index were obtained in both QC and DC methods for head (32.76 and 32.36), sinus (11.73 and 9.89), chest (6.06 and 5.11) and abdomen/pelvis (11.86 and 10.56) imaging. The highest DRL values of DLP index in both QC and DC methods are for head, abdomen/pelvis, chest and sinus CT scans, respectively. In the QC method, these values were (603.99), (478.15), (187.15), and (132.65) respectively, and in the DC method, the values were (601.84), (427.76), (219.01), and (114.81) mG.cm.
Conclusion: According to the results of this study and the lack of significant difference between the DRL values of CTDIvol and DLP indicators in both QC and DC methods, it is recommended that the centers, if they have the acceptance criteria for annual quality control, can determine the DRL by referring to the device console information from the DC method.
Volume 83, Issue 7 (October 2025)
Methods: This cross-sectional study was conducted in Children, s Medical Center from march 2022 to February 2023 on 183 patients with type 1 diabetes aged 9 to 18 years. The duration of the disease ranged from 1 year to 15 years. 44% of the populations were girls and 56% were boys. 77% were under 13 years of age and the rest were over 13 years of age. Information was completed by parents in the Achenbach electronic questionnaire (112 questions). Then, based on the standard defined for the questionnaire, the scores were classified into clinical, borderline, and normal categories.
Results: No significant differences were observed between the two sexes in terms of the incidence of various disorders. However, significant differences in the incidence of externalizing problems have been reported at different ages and different disease durations. Analysis of the mean T-scores of the studied patients showed that there were significant differences between patients older than 13 years younger than 13 years in terms of externalizing problems, anxiety/depressive disorders, attention deficit/hyperactivity disorders, law-breaking behavior, internalizing problems, and general problems. a significant relationship was observed between the study population and the duration of the illness in terms of aggressive problems, law-breaking problems, and externalizing disorders.
Average scores in externalizing disorders, affective/depressive disorders, law-breaking behavior, internalizing problems, and general problems were significantly related to different ages.
Conclusion: The results of this study show that as patients aging and more than 5 years since the onset of diabetes, the risk of developing psychiatric disorders increases. As a result, routine psychiatric screening is recommended for these children.
