Abstract

Background: The major issue to address in obesity etiology is to identify the genetic changes in the disease and their occurrence in different populations. Uncovering these genetic changes may be important in developing potential biomarkers for early diagnosis and prognosis of obesity. Among all obesity susceptibility genes studied before, convincing association has been found with variants in the FABP2 gene and this disease; however, the contributions of these genetic variants in different populations and ethnic groups are not similar. Accordingly, this study was carried out to replicate the previous findings to assess whether a missense variation (rs1799883) in this gene is associated with obesity in the Tehran Lipid and Glucose Study (TLGS) population.

Methods: A case–control study was designed to determine the possible association between rs1799883 and occurrence of obesity “in phase IV of the study between the years of 2008 to 2011”. The study group consisted of 217 subjects with body mass index (BMI, kg/m2) greater than 30 as cases and 159 healthy individual as control group (1820). All subjects were recruited among the Tehran Lipid and Glucose Study (TLGS) participants in phase IV of the study between the years of 2008 to 2011. The genomic DNA was extracted from peripheral blood leucocytes using the salting out method and subsequently subjects were genotyped for this marker using The tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). Association of risk allele with obesity was assessed using the SPSS software, version 20 (Chicago, IL, USA).

Results: The results showed no significant differences between case and control groups in terms of allele frequency (P=0.61). According to the findings, the presence of T allele as the risk allele was not associated with increased risk of obesity in carriers of this allele compared to individuals carrying the normal allele (OR=1.17; CI%95= 0.62-2.19, P=0.61).

Conclusion: The results did not support the previous findings of an association between genetic polymorphism in the FABP2 gene and risk of obesity. However, a number of replicated studies with other ethnicity are suggested to make a conclusion about the role of this genetic polymorphisms and susceptibility to obesity in Iranian population.


Isolated Fallopian Tube Torsion with Fimbrial Cyst in a Pregnant Woman: A case Report

Volume 80, Issue 10 (January 2023)
Abstract
Background: Among diseases causing acute lower abdominal pain in women, isolated fallopian tube torsion is a rare cause that occurs mainly in women of reproductive ages and if left untreated can lead to fertility problems. Immediate diagnosis and timely surgery are urgent and necessary to preserve the fertility of females. Successful pregnancy with simultaneous involvement of isolated fallopian tube torsion is one of the rare operations in the world.
Case Presentation: The reported case is a 37-year-old pregnant woman (Gravid 2, with 33-week gestational age) with nausea, vomiting and abdominal pain in August 2020 who presented to the Maryam Hospital in Karaj in August 2020. The patient was examined in the operating room under anesthesia, and pain in the right and lower abdomen was observed. There was no anorexia, and on examination, there was severe tenderness in the right lower quadrant (RLQ) area. There was no pain in other parts of the abdomen. Ultrasonography in the patient's tenderness showed an image of a tubular and cystic structure measuring 30×10 mm. In CBC test, leukocytosis with high PMN (Polymorphonuclear), (WBC: 11700 mm3 and Neutrophil: 78%) was observed. During laparotomy, isolated torsion of the right fallopian tube observed, half of which was cyanotic. Due to the confirmation of fimbriae necrosis during surgery, preservation of uterine tube integrity, fallopian tube detorsion, excision of cyanotic fimbriae and hemorrhagic cyst of fimbriae, intra-abdominal fluid suction and fimbriae repair performed. The patient discharged in good condition after two days and gave birth to a healthy baby at 38 weeks of gestation by cesarean section.
Conclusion: Isolated fallopian tube torsion should be considered as a potential differential diagnosis in patients that have acute lower abdominal pain in women of reproductive ages and even adolescents. Early diagnosis and early surgical intervention are critical to maintaining the fallopian tube and fertility in the future. Laparoscopy is one of the main diagnostic tools for assessing, management and maintenance isolated torsion of the fallopian tube.
