Mental Health and Disorders of Sex Development/Intersex Conditions in Iranian Culture: Congenital Adrenal Hyperplasia, 5-α Reductase Deficiency-Type 2, and Complete Androgen Insensitivity Syndrome

Sixty-one patients (22 patients with congenital adrenal hyperplasia [CAH] with a mean age of 14.86 years [range, 5–23], 20 patients with 5-α reductase deficiency type 2 [5α-RD-2] with a mean age of 19.5 years [range, 5–29], and 19 patients with complete androgen insensitivity syndrome [CAIS] with a mean age of 18.26 years [range, 5–28]) were evaluated using the Kiddie Schedule for Affective Disorders and Schizophrenia, the Structured Clinical Interview for DSM-IV Axis I, Axis II, and the Global Assessment Functioning Scale. All participants were female-assigned at birth. Ten patients (16.4%) transitioned to the male gender. Overall, 68% of patients had one or more lifetime Axis I disorders, including 63.6% of the CAH participants, 90% of 5α-RD-2 participants, and 52.6% of the CAIS participants. The most commonly observed were affective disorders (27.9%), gender identity disorder (27.9%), and anxiety (16.4%). Our study demonstrates that mental health of Iranian patients with DSD is at risk. This might be due to the fact that patients with DSD conditions are mostly treated medically and their mental health is often superficially addressed in developing countries such as Iran, at least in the past. We argue that it is important to pay attention to the mental health issues of patients with DSD and focus on specific issues, which may vary cross-culturally.     

25-Year Review of the Abundance and Diversity of Radiopaque Airway Foreign Bodies in Children

This study was conducted to review the abundance and diversity of radiopaque foreign bodies over a 25-year period. Overall records of 1,114 patients who underwent rigid bronchoscopy due to foreign body aspiration in the tertiary centres, Imam Khomeini and Apadana; over a 25-year period (1989–2014) were reviewed. History, clinical findings, plain radiography and bronchoscopic findings, foreign body (FB) aspiration (whether radiolucent or radiopaque), time from onset of symptoms until hospitalization, and delay time were all considered. The male/female ratio was 1.53. Most patients were aged 1–3 years (53.94 %). The most common location of foreign bodies was the right main bronchus (54.57 %). The most common type of radiopaque foreign body was meat, chicken and big fish bones (4.84 %) followed by metal objects (4.39 %). Coughing (70.82 %) and cyanosis (22.80 %) were the most common symptoms. The most common radiological findings were emphysema (32.31 %). Given that the radiological findings are highly specific as regards the detection of radiopaque FB, radiographic examination prior to bronchoscopy for FB localization and shortening the time of bronchoscopy in patients with a history of radiopaque FB aspiration can be helpful. Due to the high morbidity and mortality caused by prolong and repeated bronchoscopy, the use of newer techniques and equipment in shortening extraction time of the foreign bodies should be considered in future researches.     

Clinical observation of tongue coating of perioperative patients: factors related to the number of bacteria on the tongue before and after surgery

Background

Increased amount of tongue coating has been reported to be associated with increased bacteria count in the saliva and aspiration pneumonia in elderly people. However, the implications of tongue coating for prevention of postoperative complications in patients undergoing major oncologic or cardiac surgery has not been well documented. The purpose of this study is to investigate the number of bacteria on the tongue before and after surgery and factors affecting it.

Methods

Fifty-four patients who underwent oncologic or cardiac surgery under general anesthesia at Nagasaki University Hospital were enrolled in the study. Various demographic, tumor-related, treatment-related factors, and the number of bacteria on the tongue and in the saliva were examined, and the relationship among them was analyzed by Mann-Whitney U test, Spearman rank correlation coefficient, or multiple regression.

Results

Before surgery, no significant factors were correlated with the number of bacteria on the tongue, and there were no relationship between bacteria count on the tongue and that in the saliva. On the next day after surgery, bacteria on the tongue increased, and sex, periodontal pocket depth, feeding condition, dental plaque, blood loss, and bacteria in the saliva were correlated with bacteria on the tongue by a univariate analysis. A multivariate analysis showed that feeding condition, and amount of dental plaque were correlated with the number of bacteria.

Conclusions

Increased number of bacteria on the tongue was associated with feeding condition and amount of dental plaque. Further studies are necessary to clarify the clinical significance of dental coating in perioperative oral management of patients undergoing oncologic or cardiac surgery.

     

Incidences and risk factors of moderate-to-severe ovarian hyperstimulation syndrome and severe hemoperitoneum in 1,435,108 oocyte retrievals

Research questionWhat are the risk factors affecting the incidences of moderate-to-severe ovarian hyperstimulation syndrome (OHSS) and severe hemoperitoneum in assisted reproductive technology (ART) treatment cycles?DesignA retrospective cohort study was conducted on 1,435,108 oocyte retrieval cycles among Japanese ART registry data between 2007 and 2015. The study included 11,378 cycles with moderate-to-severe OHSS, 1182 cycles with severe hemoperitoneum, including 27 cycles with both conditions, and 1,422,575 cycles without moderate-to-severe OHSS and severe hemoperitoneum.ResultsThe incidences of moderate-to-severe OHSS and severe hemoperitoneum were 0.79% and 0.08%, respectively, and decreased by 0.57-fold and 0.29-fold from 2007 to 2015, respectively. In cycles with OHSS and cycles with hemoperitoneum women were younger (odds ratios [OR] 0.91 and 0.95, respectively) and had more retrieved oocytes (OR 1.09 and 1.01, respectively) compared with cycles without both complications. The use of a gonadotrophin-releasing hormone (GnRH) agonist protocol for ovarian stimulation was the highest risk factor in cycles with OHSS and hemoperitoneum (OR 1.83 and 1.24, respectively), followed by GnRH antagonist protocol (reference), gonadotrophin with or without oral medicine (OR 0.45 and 0.56, respectively) and natural or oral medicine (OR 0.02 and 0.19, respectively). In fresh embryo transfer, clinical pregnancy was associated with an increased risk of OHSS and hemoperitoneum (OR 1.19 and 2.34, respectively).ConclusionsThe highest risk factors affecting OHSS and hemoperitoneum were the use of a GnRH agonist protocol and clinical pregnancy following fresh embryo transfer. The incidences of OHSS and hemoperitoneum have decreased yearly with a reduction of GnRH agonist use and fresh embryo transfer.     

Association of Plasma Retinol Binding Protein-4 (RBP4) and Sonographic Grading of Fatty Liver in Obese Iranian Children

Background

The prevalence of obesity and its related comorbidities, such as fatty liver, in children is increasing worldwide mostly due to changes in diet and life-style. Many serological markers have been suggested for screening of fatty liver but investigations for finding more reliable factors are still in progress.

Objectives

This study aimed to investigate the correlation between the level of retinol binding protein-4 (RBP4) in the serum and sonographic grading of fatty-liver severity in obese Iranian children.

Patients and Methods

This case-control, double-blind study involved 51 obese children aged between five and 17 years as the case group. In addition, 35 healthy lean children with no liver problems were selected as the control group. Plasma RBP4 (using an ELISA), serum triglycerides (TG), low-density-lipoproteins (LDL), high-density-lipoproteins (HDL), total-cholesterol (Chol), and body mass index (BMI) were measured. Grading the severity of the fatty liver condition was done by an expert radiologist in the case group.

Results

RBP4 levels in obese children (19 482.9 ± 3 302.2 pg/ml) were higher than those found in the lean control group (14 295.68 ± 2 381.3 pg/ml) (P < 0.05). In the obese patients, RBP4 levels showed a significant correlation with the grade of fatty liver and BMI (P < 0.05).

Conclusions

It was found that the level of RBP4 had a strong correlation with the severity of fatty liver. Therefore, RBP4 may be considered as a useful, noninvasive predictive biomarker of intrahepatic lipid content in obese children prior to using radiological investigations. In particular, abdominal sonography, for the evaluation of intrahepatic lipid content in obese patients, as the sensitivity of a sonography is decreased due to the increased thickness of the abdominal wall as a result of fat deposits.     

Hyaluronidase in sub-Tenon's anesthesia for phacoemulsification, a double-blind randomized clinical trial

AIM: To investigate the effect of hyaluronidase use on the quality of sub-Tenon's anaesthesia for phacoemulsification. METHODS: This was a randomized, double-blind clinical trial which was conducted at Nikookari Eye Hospital for 5 months. Forty-two eyes of candidates for phacoemulsification under sub-Tenon's anaesthesia were randomly allocated to two equal groups and received either 2 mL of lidocaine 2% solution with (LH), or without (L) addition of hyaluronidase (150IU/mL). Akinesia was assessed 15 minutes after sub-Tenon’s injection. Patients and surgeon’s satisfaction, as well as the postoperative pain (the visual analogue scale, VAS) were investigated after operation. The contingency tables (including the Chi-square or Fisher's exact tests, when appropriate) and parametric analysis (the independent samples t test) were used for statistical analysis. RESULTS: Complete akinesia (33.3% vs 4.8%, P=0.04), as well as the patients (85.7% vs 57.1%, P=0.04) and surgeon’s satisfaction (87.5% vs 52.4%, P=0.02) were significantly more frequent in LH than in L group. The mean VAS was significantly lower in the same group (1.90±1.45 vs 3.00±1.55, P=0.04). CONCLUSION: Addition of hyaluronidase to lidocaine solution for sub-Tenon's anesthesia significantly improves the ocular akinesia, enhances the intra-operative patients and surgeons' satisfaction, and attenuates the postoperative pain.     

Relationship of central corneal thickness to postural IOP changes in patients with and without glaucoma in southern India

To evaluate the relationship of central corneal thickness to the changes in intraocular pressure (IOP) in the sitting and supine position. Observational case-control study. The study group included Primary open-angle and chronic angle closure glaucoma patients. The control group consisted of patients without glaucoma seen for their routine eye examination. Central corneal thickness was measured by ultrasound pachymetry. Patients were then randomized to IOP measurement by Tonopen either sitting or supine after maintaining that position for 5 min. The position was then reversed and IOP measurements taken again after 5 min. Main outcome measure was change in IOP. One hundred and eighty-two eyes (90 in cases and 92 in controls) were examined. The mean CCT was 538.11 ± 37.17 μm in the study group and 545.34 ± 36.01 μm in the control group (P = 0.185). The mean IOP in the sitting position was 19.54 ± 5.39 mmHg in cases and 14.82 ± 4.01 in controls (P < 0.001). The mean IOP in the supine position was 20.51 ± 5.48 mmHg in cases and 16.02 ± 3.24 in controls (P < 0.001). Mean IOP change from sitting to supine was statistically significant in both groups (P < 0.001 for both). Postural change was greater in cases than controls (P = 0.020). There was no correlation between postural IOP change and CCT in cases (r = 0.143, P = 0.180) and controls (r = 0.096, P = 0.362). Postural IOP change is greater in glaucoma patients than non-glaucomatous patients. There was no correlation between postural IOP change and CCT.     

The impact of heatwaves on emergency department visits in Brisbane,Australia: a time series study

Introduction

The acute health effects of heatwaves in a subtropical climate and their impact on emergency departments (ED) are not well known. The purpose of this study is to examine overt heat-related presentations to EDs associated with heatwaves in Brisbane.

Methods

Data were obtained for the summer seasons (December to February) from 2000–2012. Heatwave events were defined as two or more successive days with daily maximum temperature ≥34°C (HWD1) or ≥37°C (HWD2). Poisson generalised additive model was used to assess the effect of heatwaves on heat-related visits (International Classification of Diseases (ICD) 10 codes T67 and X30; ICD 9 codes 992 and E900.0).

Results

Overall, 628 cases presented for heat-related illnesses. The presentations significantly increased on heatwave days based on HWD1 (relative risk (RR) = 4.9, 95% confidence interval (CI): 3.8, 6.3) and HWD2 (RR = 18.5, 95% CI: 12.0, 28.4). The RRs in different age groups ranged between 3–9.2 (HWD1) and 7.5–37.5 (HWD2). High acuity visits significantly increased based on HWD1 (RR = 4.7, 95% CI: 2.3, 9.6) and HWD2 (RR = 81.7, 95% CI: 21.5, 310.0). Average length of stay in ED significantly increased by >1 hour (HWD1) and >2 hours (HWD2).

Conclusions

Heatwaves significantly increase ED visits and workload even in a subtropical climate. The degree of impact is directly related to the extent of temperature increases and varies by socio-demographic characteristics of the patients. Heatwave action plans should be tailored according to the population needs and level of vulnerability. EDs should have plans to increase their surge capacity during heatwaves.     

Rhythm and amplitude of rhythmic masticatory muscle activity during sleep in bruxers – comparison with gum chewing

Objectives: The aim of this study was to elucidate characteristics of rhythmic masticatory muscle activity (RMMA) during sleep by comparing masseteric EMG (electromyogram) activities of RMMA with gum chewing.

Method: The parts of five or more consecutive phasic bursts in RMMA of 23 bruxers were analyzed. Wilcoxon signed-rank test for matched pairs and Spearman’s correlation coefficient by the rank test were used for statistical analysis.

Results: Root mean square value of RMMA phasic burst was smaller than that during gum chewing, but correlates to that of gum chewing. The cycle of RMMA was longer than that of gum chewing due to the longer burst duration of RMMA, and variation in the cycles of RMMA was wider.

Discussion: These findings suggest that the longer but smaller EMG burst in comparison with gum chewing is one of the characteristics of RMMA. The relation between size of RMMA phasic bursts and gum chewing is also suggested.
