Background: Mutations in CYP19A1 gene have been described in both females and males and to date only 20 cases with aromatase deficiency have been reported. In newborns, aromatase deficiency should be considered in the aetiology of 46, XX DSD, after ruling out congenital adrenal hyperplasia.Objective and hypotheses: Report of a case with CYP19A1 mutation.Method: Here we report a patient who was presenting at the age of 20 years old ...

The majority of patients with Variations of Sex Development (VSD) lack a genetic diagnosis. Patients that are born with atypical chromosomal, gonadal, or phenotypical sex, present a wide spectrum of phenotypes that are often associated with ambiguous genitalia, infertility as well as increased susceptibility to testicular or ovarian cancer. Many different genetic causes of VSD have been reported [2], but for more than 50% [3] of all VSD patients, the molecular cause of their c...

Background: Persistent Müllerian duct syndrome (PMDS) is a relatively rare autosomal recessive disorder of sex development (DSD), characterized by the presence of Müllerian duct derivatives in 46,XY phenotypic males. PMDS is due to mutations in the AMH gene or its type II receptor gene AMHR2. To date; more than 50 different mutations of the anti-Müllerian hormone (AMH) gene have been reported.Case report: Here, we report a novel mutation o...

Background: Anti-Mullerian hormone (AMH) is produced by Sertoli cells and signals through two transmembrane receptors (AMHR), specific type II and type I, leading to regression of Mullerian ducts (uterus and fallobian tubes) during fetal male sex differentiation. Mutations of AMH and AMHR-II genes lead to persistence of Mullerian ducts in males. These conditions are transmitted in a recessive autosomal pattern and are symptomatic in 46,XY phenotypic males.<p class="abstext...

Introduction: Since diabetes mellitus is one of the major non-communicable diseases, therefore it is important taking this subject in some details during the undergraduate medical course, to prepare the students for recognizing the disease and understanding its management. In Sultan Qaboos University, the medical students go through a pre-internship training period, immediately after their final year of clerkship and just before starting their internship.<...

Background: Type 1 DM (T1DM) is a chronic condition characterized by persistent hyperglycemia; which can impair immunity and increase susceptibility to infections. Latent TB infection (LTBI) is a subclinical infection caused by Myobactaeria tuberculosis antigens without clinical, bacteriological or radiological evidence of manifest TB disease. Tuberculin test (TST) is an inexpensive test used to identify LTBI status, but has limitations. False positive TST can...

Background: Clinical spectrum of 46 XY DSD is characterized by a greatest diversity. Atypical sex development can occur through different steps of testicular differentiation. Etiologies of 46 XY DSD are termed gonadal dysgenesis, hormonal dysfunction and action. Its global incidence is unknown but the most common presentation, hypospadias, is understood to occur in 1 in 125 male births, and complete androgen insensitivity has an incidence of 1:20,000 people.</...

Background: In diabetic athletes, glycogen depletion can contribute to the early development of starvation ketones as is demonstrated by our patient.Case presentation: Our patient, a 15-year-old male triathlete with type 1 diabetes for 5 years was referred to our tertiary center because of suboptimal regulation on continuous subcutaneous insulin infusion (CSII). He frequently awoke with nausea and ketosis, which was initially attributed to failure of ins...

Background: Neonatal severe primary hyperparathyroidism (NSHPT, MIM 23900) is a potentially lethal autosomal recessive disorder characterized by severe hypercalcemia, markedly elevated serum PTH levels and skeletal abnormalities that include multiple fractures, demineralization and erosions. It is secondary to biallelic loss of function mutation in the CASR gene that encodes the calcium sensing receptor.Case presentation: We identified a 10-day old baby ...

Background: Abnormal cardiac development leading to CHD can be associated with abnormal placental development with abnormal trophoblast invasion and remodeling resulting in abnormal transfer of nutrients and oxygen.Objective and hypotheses: We measured the anthropometric parameters (length, weight, and head circumference) and the placental weight of 49 FT newborns (gestation period >36 weeks) infants with CHD ((cyanotic (n=8) and acyanotic (...
