Evaluation of foot self-care status and foot screening problems in patients with diabetes in Iran: a national multicenter study.

BACKGROUND AND PURPOSE: The lack of timely foot care among individuals with diabetics often lead to ulceration followed by infection and amputation. This study aimed to evaluate the foot self-care status and foot screening practices among patients with type 2 diabetes in various cities across Iran. METHODS: The cross-sectional descriptive study was performed on patients with type 2 diabetes in 10 main cities of Iran. The information about demographic and lifestyle factors, diabetes history, and diabetic foot self-care (DFSQ) was assessed. Additionally, the neurological and vascular condition of the foot were screened by Inlow's 60-Second Screen. RESULTS: The study included 1094 diabetic patients with, with a majority being female (64.8%) and married (92.5%). The average age of the participants was 57.6 ± 10.21 (mean ± SD), and the mean duration of diabetes was 11.56 ± 7.41 years. Based on Inlow's 60-Second Screen criteria, 58% of the patients should undergo yearly foot ulcer screening, 47% exhibited peripheral neuropathy, and 37% were found to have inappropriate footwear. CONCLUSION: The high prevalence of peripheral neuropathy observed in approximately half of the participants across different regions of Iran underscores the importance of continuous patient education regarding foot care and appropriate footwear. Furthermore, regular foot ulcer screenings, following the recommended intervals outlined in Inlow's screening protocol, should be implemented to effectively manage diabetic foot complications.

Nationwide Prevalence of Diabetes and Prediabetes and Associated Risk Factors Among Iranian Adults: Analysis of Data from PERSIAN Cohort Study.

INTRODUCTION: Over the past decades prevalence of diabetes has increased in Iran and other countries. This study aimed to update the prevalence of diabetes and prediabetes in Iran and to determine associated sociodemographic risk factors, as well as diabetes awareness and control. METHODS: This is a nationally representative cross-sectional survey that included 163,770 Iranian adults aged 35-70 years, from different ethnic backgrounds, between 2014 and 2020. Diabetes was diagnosed at fasting blood sugar of ≥ 6.99 mmol/L (126 mg/dL), or receiving blood glucose-lowering treatment. Multivariable logistic regression was applied to detect determinants associated with prevalence of diabetes and prediabetes, as well as predictors of diabetes awareness and glycemic control. RESULTS: Sex- and age-standardized prevalence of diabetes and prediabetes was 15.0% (95% CI 12.6-17.3) and 25.4% (18.6-32.1), respectively. Among patients with diabetes, 79.6% (76.2-82.9) were aware of their diabetes. Glycemic control was achieved in 41.2% (37.5-44.8) of patients who received treatment. Older age, obesity, high waist to hip ratio (WHR), and specific ethnic background were associated with a significant risk of diabetes and prediabetes. Higher awareness of diabetes was observed in older patients, married individuals, those with high WHR, and individuals with high wealth score. Moreover, glycemic control was significantly better in women, obese individuals, those with high physical activity, educational attainment, and specific ethnic background. CONCLUSIONS: The prevalence of diabetes and prediabetes is increasing at an alarming rate in Iranian adults. High proportion of uncontrolled patients require particular initiatives to be integrated in the health care system.

The effect of vitamin D supplementation on flow-mediated dilatation, oxidized LDL and intracellular adhesion molecule 1 on type 2 diabetic patients with hypertension: A randomized, placebo-controlled, double-blind trial.

AIMS: Current study aimed to evaluate the effect of vitamin D supplementation on flow-mediated dilatation (FMD), oxidized LDL (oxLDL) and intracellular adhesion molecule 1 (ICAM1) in type 2 diabetic patients with hypertension. METHODS: In a double-blinded, placebo-controlled trial, 44 patients were randomly divided into vitamin D group (2000 IU/d, n = 23) and placebo group (control, n = 21) for 12 weeks. Vascular function with FMD, Serum 25-OH vitamin D, oxLDL and ICAM1 were assessed at the baseline and after the intervention. This clinical trial was registered at Iranian Registry of Clinical Trials (IRCT20191223045861N1). RESULTS: In intervention group serum level of vitamin D increased from 32.42 ± 10.56 to 40.45 ± 12.94 (p < 0.001). In the vitamin D group, oxLDL and ICAM1 significantly decreased and FMD increased significantly in both groups (p < 0.001). The level of oxLDL (p = 0.017) and ICAM1 (p < 0.001) were significantly lower in the vitamin D group than the placebo group and FMD (p < 0.001) was significantly higher in the vitamin D group. CONCLUSIONS: Vitamin D supplementation of 2000 IU/d for 12 weeks can improve endothelial function and decrease ICAM1 and oxLDL in type 2 diabetic patients with hypertension.

"Tracheomalacia after Thyroidectomy," Does it Truly Exist?

AIM: Tracheomalacia is a potentially life-threatening, but a rare complication of thyroidectomy. In previous studies, the incidence rate was very different. Considering the relatively high prevalence of goiter and thyroidectomy in the West Azerbaijan region, we designed this study to determine the tracheomalacia incidence in patients who underwent thyroidectomy within a 10-year interval. MATERIALS AND METHODS: This retrospective study was done in Urmia Imam Khomeini Hospital in West Azarbayjan Province. Demographic characteristics including the age and sex of patients who underwent thyroidectomy between 2007 and 2017 and also the incidence of tracheomalacia after surgery were recorded. RESULTS: From 2007 to 2017, total 1236 thyroidectomy were performed. The patients' age ranged from 15 to 83-year-old with a mean age of patients was 44.5 ± 13.81 years old. Two hundred and twenty-nine patients (19%) were male and 1007 (81%) were female. We did not find any cases of tracheomalacia after thyroidectomy in our study population. CONCLUSION: Based on the results of this study, it seems that with the necessary precautions, the incidence of tracheomalacia can reach zero.

ACS-NSQIP risk calculator predicts cohort but not individual risk of complication following colorectal resection.

OBJECTIVE: Compare the ACS-NSQIP risk calculator with institutional risk for colorectal surgery. METHODS: Actual and predicted outcomes were compared for both cohort and individuals. RESULTS: For the cohort, the risk calculator was accurate for 7/8 outcomes; there were more serious complications than predicted (19.4 vs 14.7%, p < 0.05). Risk calculator Brier scores and null Brier scores were comparable. PATIENTS: with better outcomes than predicted were current smokers (OR 4.3 95% CI 1.2-15.4), ASA ≥ 3 (OR 10.4, 95% CI 2.8-39.2), underwent total/subtotal colectomy (OR 3.5, 95% CI 1.1-12.2) or operated by Surgeon 2 (OR 2.9, 95% CI 1.4-11.6). Patients with serious complications who had low predicted risk had low ASA (OR 10.5, 95% CI 1.3-82.6), and underwent operation by Surgeon 2 (OR 11.8, 95% CI 2.5, 55.2). LIMITATIONS: Single center study, sample size may bias subgroup analyses. CONCLUSIONS: The ACS NSQIP calculator did not predict outcome better than sample risk.

Readmissions after colorectal surgery: not all are equal.

PURPOSE: This study aims to assess factors associated with preventable readmissions after colorectal resection. METHODS: All readmissions following colorectal resection from May 2013 to May 2016 at an academic medical center were reviewed. Readmissions that could be prevented were identified. Factors associated with preventable readmission were assessed using logistic regression. RESULTS: Of 686 patients discharged during the study period, there were 75 patients (11%) with unplanned readmission. Twenty-nine readmissions (39%) were preventable-these readmissions were due to dehydration or acute kidney injury, pain, ostomy complications, and gastrointestinal bleeding. On regression analysis, the strongest preoperative risk factors associated with preventable readmission were urgent or emergent operation (OR 4.0, 95% CI 1.6-9.9), recent myocardial infarction (OR 2.9, 95% CI 1.0-9.0), total or subtotal colectomy (OR 2.8, 95% CI 1.1-7.3), and American Society of Anesthesiologist score ≥ 3 (OR 2.2, 95% CI 1.0-4.7). Intraoperative risk factors associated with preventable readmission included intraoperative stapler complication (OR 24.2, 95% CI 1.5-397). Postoperative risk factors associated with preventable readmission included postoperative arrhythmia (OR 5.6, 95% CI 2.0-16.1), and postoperative anemia (OR 2.6, 95% CI 1.2-5.7). On multivariable analysis while controlling for procedure type, urgent or emergent operation (OR 2.9, 95% CI 1.1-8.2), intraoperative stapler complication (OR 37.5, 95% CI 2.3-627.8), and postoperative arrhythmia (OR 4, 95% CI 1.3-12.8) remained statistically significant. CONCLUSION: Approximately 40% of readmissions following colorectal surgery are potentially preventable. Since specific patients and factors that are associated with preventable readmission can be identified, resources should be targeted to factors associated with preventable readmissions.

Use of an ACE inhibitor or angiotensin receptor blocker is a major risk factor for dehydration requiring readmission in the setting of a new ileostomy.

PURPOSE: Diverting ileostomies help prevent major complications related to anastomoses after colorectal resection but can cause metabolic derangement and hypovolemia, leading to readmission. This paper aims to determine whether angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) use increased the risk of readmission, or readmission specifically for dehydration after new ileostomy creation. METHODS: Retrospective analysis of patients undergoing diverting ileostomy at a tertiary-care hospital, 2009-2015. Primary outcome was 60-day readmission for dehydration; secondary outcomes included 60-day readmission for any cause, or for infection obstruction. RESULTS: Ninety-nine patients underwent diverting ileostomy creation, 59% with a primary diagnosis of colorectal cancer. The 60-day readmission rate was 36% (n = 36). Of readmitted patients, 39% (n = 14) were admitted for dehydration. Other readmission reasons were infection (33%) and obstruction (3%). The majority (64%, n = 9) of patients readmitted for dehydration were taking either an ACEi or an ARB. Compared to patients not readmitted for dehydration, those who were readmitted for dehydration were more likely to be on an ACEi or an ARB (11/85, 13% vs. 9/14, 64%). After controlling for covariates, ACEi or ARB use was significantly associated with risk of readmission (p < 0.0001, odds ratio = 13.56, 95% confidence interval 3.54-51.92,). No other diuretic agent was statistically associated with readmission for dehydration. CONCLUSIONS: ACEi and ARB use is a significant risk factor for readmission for dehydration following diverting ileostomy creation. Consideration should be given to withholding these medications after ileostomy creation to reduce this risk.

Specific Factors Predict the Risk for Urgent and Emergent Colectomy in Patients Undergoing Surgery for Diverticulitis.

The aim of this study was to identify preoperative characteristics that may determine the need for emergency surgery for diverticulitis and assess postoperative outcomes for these patients when compared with elective surgery. All patients included in the ACS-NSQIP-targeted colectomy database from 2012 to 2013 who underwent colectomy with an underlying diagnosis of diverticulitis were included. Preoperative characteristics and 30-day postoperative outcomes were evaluated for patients who underwent elective versus emergent/urgent surgery using univariable and multivariable analyses. Of 8708 patients with diverticular disease, 28.1 per cent underwent emergent/urgent colectomy. Patients who underwent emergent/urgent colectomy had greater preoperative steroid use, diabetes mellitus, disseminated cancer, chronic renal failure, hypertension, chronic heart failure, chronic liver disease, COPD, and dependent functional health status (P < 0001). There were more patients with age >65 years (P < 0001), smoking history (P < 0.05), and BMI < 18.5 kg/m² (P < 0001) in the emergent/urgent colectomy group. After performing multivariable analysis, preoperative steroid use, weight loss >10 per cent, BMI < 18 kg/m², smoking, age > 65, and comorbid conditions were associated with a higher rate of emergent/urgent surgery. Mortality (5.2% vs 0.2%) and infectious and noninfectious complications were higher after nonelective colectomy. Emergent/urgent colectomy was also associated with longer hospital stay and reoperation. Emergency and urgent colectomy for diverticulitis is associated with significantly worse outcomes than after elective surgery, and patients with comorbid conditions who develop attacks of diverticulitis may in fact be the population that might best benefit from a lower threshold for an elective colectomy.

Optimal Glycemic and Hemoglobin A1c Thresholds for Diagnosing Diabetes Based on Prevalence of Retinopathy in an Iranian Population.

BACKGROUND: The use of glycemic thresholds for diabetes diagnosis is controversial. However, no information is available regarding glycemic and glycated hemoglobin (HbA1c) thresholds for detecting diabetic retinopathy (DR) in the Iranian population. OBJECTIVES: The main purpose of the current investigation was to examine the association of fasting plasma glucose (FPG) and HbA1c levels with diabetic retinopathy (DR), and to determine the relevant cut-off levels in an Iranian population. PATIENTS AND METHODS: This cross-sectional, population-based study was performed during 2012-2013 in Urmia, the capital of West Azerbaijan province, Iran. The subjects were 3,010 Iranians aged 40-81 years. The FPG levels were determined using the glucose oxidase method whereas, the HbA1c values were measured using a standardized assay by high performance liquid chromatography. DR was evaluated by an examination of the fundus photograph of each eye. The photographs were graded according to the international clinical diabetic retinopathy disease severity scale by photograph graders who were masked to the clinical information. RESULTS: Of the subjects, 59 had DR. The prevalence of DR increased steeply between the ninth and the tenth deciles for both variables. The ROC curve analysis showed overall glycemic thresholds for DR of 6.5 mmol/L (117 mg/dL) for FPG and 6.2% (44 mmol/mol) for HbA1c. The sensitivities and specificities were 78.0% and 87.1% for FPG and 89.8% and 89.5% for HbA1c, respectively. The areas under the ROC curves indicated that HbA1c was a stronger discriminator of retinopathy: the area under curve was 0.880 for FPG and 0.946 for HbA1c P < 0.001). However, the thresholds for detecting DR for the two measures showed no significant differences after excluding individuals receiving anti-hyperglycemic medication. CONCLUSIONS: These findings suggest that the HbA1c and FPG thresholds for detecting diabetes in the Iranian population are lower than the current diagnostic criteria.

Altered Concentrations of Copper, Zinc, and Iron are Associated With Increased Levels of Glycated Hemoglobin in Patients With Type 2 Diabetes Mellitus and Their First-Degree Relatives.

BACKGROUND: The altered levels of some essential trace elements and antioxidant minerals have been observed in diabetic patients. OBJECTIVES: The aim of the present study was to compare the concentrations of essential trace elements, copper (Cu), zinc (Zn), and iron (Fe) in the serum of patients who have type 2 diabetes mellitus (T2DM) with those of their non-diabetic first-degree relatives (FDR) and control subjects. The association between glycated hemoglobin (HbA1c) and levels of metals was also evaluated. PATIENTS AND METHODS: We studied 46 subjects with T2DM, 46 FDR, and 50 control subjects matched for age and sex. Serum concentrations of Cu, Zn, and Fe were measured by colorimetric kit. Fasting blood glucose (FBG) and HbA1c were assayed using the standard kit. RESULTS: An imbalance in the levels of the studied metals was observed in both patients with T2DM and FDR. We found significantly decreased levels of Zn and higher levels of Cu and Fe in the patients with T2DM and FDR when compared with the control subjects (P < 0.05). HbA1c levels were positively correlated with Cu and Fe and inversely correlated with Zn in the patients with T2DM and FDR (P < 0.05). CONCLUSIONS: The patients with T2DM and FDR had altered contents of Cu, Zn, and Fe that might be a predisposing factor to the development of diabetes in future or vice versa the result of diabetes development. Impaired metabolism of these elements may contribute to the augmented risk of developing type 2 diabetes mellitus later in the life of their first-degree relatives.

Evaluation of safety and efficacy of 980-nm diode laser-assisted lipolysis versus traditional liposuction for submental rejuvenation: A randomized clinical trial.

BACKGROUND: Submental fat accumulation and skin laxity is a frequent concern of cosmetic patients. OBJECTIVE: The aim of this randomized prospective controlled clinical trial was to compare the efficacy and safety of laser-assisted lipolysis and liposuction in the submental rejuvenation. MATERIAL AND METHODS: Thirty-six female adults were enrolled in this clinical trial and were categorized into two groups: group 1 underwent 980-nm diode laser with the power of 6-8 W and group 2 underwent traditional liposuction. Patients were evaluated with ultrasonography 2 weeks and 2 months after the procedures. RESULTS: Ultrasonographic evaluation reported the significant reduction of fat thickness in each group compared with the baseline (p value < 0.001). At the 2 weeks and 2 months follow-up visit, fat thickness reduction was significantly higher in the lipolysis group (p value < 0.05). Overall patients' satisfaction in lipolysis group was higher than liposuction with 11 (61%) of lipolysis patients being very satisfied in contrast to 10 (55.5%) of liposuction patients reporting "dissatisfied or neutral" results. CONCLUSION: Laser-assisted lipolysis using 980-nm diode is approved to be safe and effective for skin tightening and rejuvenation of the submental area and seems to be a better option than traditional techniques for treatment of this cosmetic problem.

Impaired endothelial function in siblings of patients with diabetic mellitus type 2.

BACKGROUND: Endothelial dysfunction is considered as a risk factor for cardiovascular disease, which is a consistent finding in diabetic mellitus type 2 (DMT2). First-degree relatives of DMT2 patients have a higher risk of developing DMT2 later on the life. We aimed to investigate whether impaired endothelial function exists in siblings of DMT2 patients. METHODS: As endothelial function markers, plasma E-selectin, soluble inter-cellular adhesion molecule-1 (sICAM-1), and endothelin-1 (ET-1) were measured on 27 DMT2 patients (9 m/18f; mean age: 48.48 ± 6.75 years), 28 siblings of DMT2 patients (14 m/14f; mean age: 44.54 ± 7.10 years), and 30 control subjects (18 m/12f; mean age: 44.72± 7.56 years) without any family history of diabetes. All the groups were matched by gender, age, and body mass index (BMI). RESULTS: Plasma levels of ET-1, sICAM-1, and E-selectin were significantly higher in the DMT2 group compared to the control group (ET-1:0.79 ± 1.63 pg/ml vs. 0.33 ± 0.08 pg/ml; PCD = 0.049, sICAM-1: 71.15 ± 27.20 ng/ml vs. 34.57 ± 22.56 ng/ml; PCD = 0.001, E-selectin: 22.45 ± 11.57 ng/ml vs. 16.28 ± 7.50 ng/ml; PCD =0.026). There was a significant difference in sICAM-1 levels between siblings (62.08 ± 26.37 ng/ml) and controls (PCS = 0.002), but not between siblings and DMT2 patients (PSD = 0.411). Moreover, a significant difference was observed in ET-1 levels between siblings (0.75 ± 1.26 pg/ml) and controls (PCS = 0.031), but not between siblings and DMT2 patients (PSD = 0.751). There was also a significant difference in E-selectin levels between DMT2 patients and siblings (16.56 ± 8.71 ng/ml; PSD =0.028); however, the difference in E-selectin levels was not statistically significant between siblings and controls (PCS = 0.919). CONCLUSION: Endothelial function markers in the siblings of DMT2 patients are increased in comparision to the control group Therefore; family history in the DMT2 patients seems to be a risk factor for endothelial function. Furthermore, endothelial dysfunction is available very early in the DMT2 patients, even before overt hyperglycemia ensues (in siblings), and may play a key role in the etiopathology of the vasculopathy associated with DMT2.

Low-power fractional CO2 laser versus low-fluence Q-switch 1,064 nm Nd:YAG laser for treatment of melasma: a randomized, controlled, split-face study.

BACKGROUND: Various laser treatments are currently available for melasma but their use remains challenging because of potential side effects. OBJECTIVE: The aim of this randomized controlled study was to compare the efficacy and safety of low-fluence Q-switch 1,064 nm Nd:YAG and low-power fractional CO2 laser using a split-face design. MATERIALS AND METHODS: A total of 40 female patients with symmetric melasma were enrolled to the study and each side of their face was randomly allocated to either low-fluence Q-switch 1,064 nm Nd:YAG or low-power fractional CO2 laser. They were treated every 3 weeks for five consecutive sessions and followed for 2 months after the last treatment session. Response to treatment was assessed using the Melanin Index (MI) score, modified Melasma Area and Severity Index (mMASI) score, and a subjective self-assessment method. RESULTS: At the 2-month follow-up visit, both sides of the face had statistically significant reductions in the MI and mMASI scores compared with the first visit (p < 0.001). The differences between the mean MI and mMASI scores at baseline and at 2-month follow-up were compared between the two treatments and results showed that the reduction of MI and mMASI score in the fractional CO2 laser-treated side was significantly more than on the Q-switch 1,064 nm Nd:YAG laser-treated side (p < 0.001). There were no significant adverse effects with either of the laser treatments. CONCLUSION: The present study shows that low-power fractional CO2 laser is safe and effective and can be considered as a valuable approach in the treatment of melasma.

Sentinel lymph node mapping and biopsy using radioactive tracer in gastric cancer.

BACKGROUND: Lymph node metastasis is one of the most important prognostic factors in gastric cancer survival. Sentinel lymph node (SLN) mapping and biopsy may reduce the extension of lymph node dissection by determination of lymph node involvement. The current study prospectively evaluates the feasibility and reliability of SLN biopsy in gastric cancer. METHODS: A total of 30 patients with gastric cancer with a preoperative imaging stage of T1-T2 or T3, N0 and M0 were enrolled in the study. Furthermore, 2-16 h prior to each operation, (99m) Tc-sulphur colloid solution (0.5 mL, 2 mCi/mL) was endoscopically injected into the submucosal layer around the primary lesion. Lymph nodes were examined using a hand-held gamma probe. Subsequently, a total or subtotal gastrectomy and D2 lymphadenectomy was performed in each patient. RESULTS: The success rate of SLN biopsy was 100%. Sensitivity, specificity, positive predictive value and negative predictive value were 91.7%, 100%, 100% and 75%, respectively. Both of the two false-negative cases were in the T3 group. In cases of T2 tumours, the sensitivity was 100%. DISCUSSION: SLN biopsy using a gamma probe in early stage gastric cancer seems to be a safe, feasible and accurate procedure with high sensitivity in predicting regional lymph node involvement.

Short fourth and fifth metacarpals in a case of idiopathic primary hypoparathyroidism.

Shortening of metacarpals is a useful diagnostic marker in patients with pseudohypoparathyroidism type Ia (PHP-Ia) with Albright's hereditary osteodystrophy (AHO) phenotype or pseudopseudohypoparathyroidism (PPHP). There are very rare reports of metacarpals shortening in idiopathic primary hypoparathyroidism (IPH) cases in the literature. Here we described a young woman with IPH who presented with hypocalcaemia and generalized tonic-clonic seizure. She had shortening of forth and fifth metacarpals which was prominent in her right hand. Based on our finding and other previous case reports we conclude that metarpals shortening is not a specific finding of PHP-Ia or PPHP and it may be found in IPH cases.

Relationship between continuous use of low-dose enteric-coated aspirin and gastrointestinal injuries in patients with gastrointestinal hemorrhage.

BACKGROUND/AIMS: Gastrointestinal disorders are important side effects of aspirin therapy, even if the low-dose enteric-coated form is administered. The aim of the current study was to present the upper and lower endoscopic features of patients with gastrointestinal hemorrhage using low-dose enteric-coated aspirin. MATERIALS AND METHODS: This prospective study was conducted among 633 consecutive patients with gastrointestinal hemorrhage who admitted to our tertiary referral hospital for endoscopy assessment. Patients were divided into two groups as low-dose aspirin users (n=168) and non-aspirin users (n=495). Aspirin users included those who were taking 80-100 mg of enteric-coated aspirin per day. RESULTS: Ulcer lesions were found in 78 patients in the aspirin user group and in 113 patients in the control group. Prevalence of duodenal ulcer was statistically similar between the two groups; however, gastric ulcer was seen more in the aspirin-user group. The use of low-dose aspirin could strongly predict gastric ulcers in the patients examined by endoscopy (p<0.001). Overall prevalence of peptic ulcer disease in those with confirmed Helicobacter pylori infection was significantly higher than in non-infected ones (p<0.001). The presence of this infection was strongly associated with peptic ulcer disease in the aspirin-user group (p<0.001). Multivariable analysis also demonstrated that the use of aspirin had a main triggering effect on short-term mortality following gastrointestinal endoscopy (p=0.003). CONCLUSIONS: Low-dose enteric-coated aspirin causes significant gastric endoscopic lesions and even predicts mortality due to progression of gastrointestinal disorders.

A 32-year-old Man with Normokalemic Thyrotoxic Periodic Paralysis.

Thyrotoxic Periodic Paralysis (TPP) is a rare and life threatening condition commonly occurring in young Asian males. It is characterized by acute paralytic attacks and hypokalemia in association with thyrotoxicosis. Serum potassium levels may be normal in rare cases of TPP. The diagnosis of normokalemic TPP may be overlooked and/or delayed in most cases. Here, we describe a 32-year-old Iranian man with normokalemic TPP misdiagnosed as somatization disorder with the correct diagnosis made one year after the onset of symptoms.
