Linking climate along with transmittable disease trends inside the Northern/Arctic Area.
No statistically significant relationship was identified among genotypes belonging to the patient and control groups although sample sizes were relatively small and the analysis should be repeated in a larger cohort.
This study is the first to investigate the relationship between ovarian cancer and the Val158Met polymorphism in the COMT gene in a Turkish population. No statistically significant relationship was identified among genotypes belonging to the patient and control groups although sample sizes were relatively small and the analysis should be repeated in a larger cohort.
By using magnetic resonance spectroscopy (MRS) to determine metabolite content of growing nfollicle in patients with polycystic ovary syndrome (PCOS) receiving recombinant FSH, clomiphene citrate (CC) or aromatase inhibitor (AI) for ovarian stimulation.

30 patients diagnosed with PCOS and infertility and scheduled for ovarian stimulation were divided into 3 equal groups according to the drugs they took as follows rFSH (n 10), or CC (n 10), or AI (n = 10). Five fertile cases were determined as the control group. When the follicle diameters reached 16-18 mm in each group, patients were directed to the MRS and the metabolite content of a dominant follicle was analyzed. N-acetylaspartate (NAA), lactate (Lac), creatine (Cr), and choline (Cho) metabolite levels determined in the spectrum were measured in ppm.

Approximately 3-fold decrease in dominant follicle Cho content was found in patients receiving CC compared to control subjects. Similarly, the dominant follicle Cho intensities of patients given rFSH andite content. Developmental capacity of growing egg can be determined non-invasively with MRS.
Lymphomatoid papulosis (LyP) is an indolent skin disease with variable clinical features classified among the primary cutaneous CD30+ T-cell lymphoproliferative disorders. It may show association with cutaneous and systemic lymphomas. We aimed to identify the frequency and characteristics of associated lymphomas among Turkish patients with LyP and to determine the risk factors for secondary lymphomas.

The files of patients diagnosed with LyP between 1998 and 2018 in a tertiary dermatology clinic were retrospectively analyzed. Univariate and multivariate models were used to assess the possible risk factors for secondary lymphomas, such as demographic and clinical characteristics of the patients.

Among 61 patients (47 adults, 14 children) with LyP, a total of 22 secondary lymphomas were observed in 20 patients. Nineteen of them were adults. Mycosis fungoides (MF) was the major associated lymphoma (n=19) followed by systemic anaplastic large cell lymphoma (ALCL) (n=2) and primary cutaneous ALCL (n=1). The most common stage in patients with accompanying MF was stage IB (n=11). While 18 patients showed the classical type of MF, one patient had folliculotropic MF. When the risk factors for association between LyP and other lymphomas were evaluated, only older age was found to be a significant risk factor and existence of ulcerated lesions was found to be a negative indicator.

LyP is not rare in the pediatric population. MF is the most common associated lymphoma in patients with LyP. Adult LyP patients are more commonly associated with secondary lymphomas than pediatric patients. Older age at the time of diagnosis of LyP is a significant risk factor for associated lymphomas.

The classical 21-hydroxylase deficiency is characterised by virilisation of the external genitalia in females and hypocortisolism. Hyponatremia and hyperkalemia are among the common biochemical findings. Familial hypokalemic periodic paralysis (FHPP) is a rare disorder in which affected individuals may experience paralytic episodes associated with hypokalemia, caused by pathogenic variants in SCN4A and CACNA1S. A 14-year-old female, who had been diagnosed with classical 21-hydroxylase deficiency and treated with hydrocortisone and fludrocortisone since early infancy, presented with acute onset weakness. The laboratory results revealed a remarkably low serum potassium level. The family history revealed that both her father and uncle had the same hypokalemia symptoms, which suggested an FHPP diagnosis. We found two previously reported homozygous variants in CYP21A2 (p.Ile173Asn) and SCN4A (p.Arg672His) in the patient. Therefore, diagnoses of simple virilising 21-hydroxylase deficiency and FHPP were genetically confirmed. Here, FPHH and chronic overtreatment with fludrocortisone may explain the presentation of our patient with severe hypokalemia. The family's medical history, which is always a valuable clue, should be investigated in detail since we can encounter rare situations in geographies where consanguineous marriages are common and the genetic pool is diverse. In patients with congenital adrenal hyperplasia, care should be taken to avoid overtreatment with fludrocortisone. Androgens may have triggered the hypokalemic attack in familial hypokalemic periodic paralysis, as supported in a previous study.The enzyme 17-β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) catalyzes the biosynthesis of testosterone from Δ4-androstenedione, and plays an important role in the final steps of androgen synthesis. Proteases inhibitor 17β-HSD3 deficiency originates from mutations in the HSD17B gene, causing an autosomal recessive 46, XY sex developmental disorder (DSD). Patients with 46, XY karyotype can exhibit a wide phenotypic spectrum varying from complete external female genitalia to male genitalia with hypospadias. This study reports a case of 17β-HSD3 deficiency diagnosed in the infantile period who was later found to have a novel HSD17B3 gene variation. The 14-month old patient, who exhibited a female phenotype, presented with a bilateral lump in the inguinal area. Imaging revealed bilateral testicular gonads in the inguinal area. Hormonal evaluation showed low levels of basal and stimulated serum testosterone (T), a high level of androstenedione (A), and a low T/A ratio. Chromosomal analysis showed 46, XY karyotype. The patient's sequence analysis of the HSD17B3 gene revealed a c.
