The importance of hypophosphatemia in the clinical management of primary hyperparathyroidism.

AIM: The levels of serum phosphorus (P) are low or low-normal in primary hyperparathyroidism (PHPT), and there is an inverse relationship between the levels of parathormone (PTH) and P. However, when considering the diagnostic and surgical indication criteria of PHPT, serum P levels are generally ignored. The aim of this study was to retrospectively evaluate the association of serum P levels with the clinical outcomes of PHPT. MATERIALS AND METHODS: A retrospective evaluation was made of the data of 424 consecutive patients (370 females, 54 males) with PHPT who presented at our centre. RESULTS: The mean age of the study population was 57 ± 11.68 years. The mean P was 2.57 ± 0.53 mg/dl. Asymptomatic disease was determined in 199 (47%) patients. Male patients had significantly lower levels of P. Symptomatic patients and patients with renal stones, vitamin D < 20 µg/l, calcium level ≥ 11.2 mg/dl, 24 h urinary calcium > 400 mg/day, or hypomagnesemia, were seen to have significantly lower levels of P (p < 0.05). Hypophosphatemia (hypoP) was found in 202 of 424 patients (47%), and these patients had a higher rate of symptomatic disease (63% to 44%, p < .0001). Of the 61 (88%) patients with moderate hypoP, 54 (88%) had at least one of the surgical criteria. A statistically significant increase in the incidence of hypoP was determined in symptomatic and male patients. In the patients with hypoP, serum PTH and urine calcium levels were found to be higher, and lumbar T-scores and serum vitamin D levels were lower. The patients with hypoP had higher rates of renal stones and osteoporosis (p < 0.05). CONCLUSIONS: The current study results show that hypoP is associated with a higher risk of osteoporosis and renal stones in PHPT patients. Even if patients are asymptomatic, moderate hypoP may be associated with poor outcomes of PHPT. Therefore, moderate hypoP may be a new criterion for parathyroidectomy, regardless of hypercalcemia level.

Synthesis of new benzimidazole derivatives containing 1,3,4-thiadiazole: their in vitro antimicrobial, in silico molecular docking and molecular dynamic simulations studies.

A series of some new benzimidazole-1,3,4-thiadiazoles was synthesized. The structures of target substances were confirmed by using 1H-NMR and 13С-NMR spectroscopy, mass spectrometry and elemental analysis. The synthesized compounds were evaluated for antimicrobial activity against six bacterial strains namely Escherichia coli (ATCC 25922), Klebsiella pneumoniae (ATCC 13883), Pseudomonas aeruginosa (ATCC 27853), Enterococcus faecalis (ATCC 2942), Bacillus subtilis (ATCC 6633), Staphylococcus aureus (ATCC 29213)and four fungal strains namely Candida albicans (ATCC 24433), Candida krusei (ATCC 6258), Candida parapsilosis (ATCC 22019) and Candida glabrata (ATCC 9). Antimicrobial data revealed that compounds 4f and 4i with MIC of < 0.97 µg/mL were found to be most effective against E. coli. Among the studied molecules, compounds 4f and 4i showed the best antifungal activity with MIC value of 1.95 µg/mL. Additionally, docking studies were performed towards the most promising compounds 4f and 4i, in the active site of DNA gyrase revealing strong interactions. A molecular dynamics (MD) simulation analysis was also used to investigate the dynamic nature, binding interaction, and protein-ligand stability.

A green approach for the treatment of dye and surfactant contaminated industrial wastewater / Uma abordagem verde para o tratamento de águas residuais industriais contaminadas por tintas e surfactantes

Abstract Synthetic dyes, particularly reactive and acid dyes, are commonly used in the textile industry because of their advantages as excellent color fastness and brightness. Also, surfactants are used for an increment of coloring success in the textile industry. One of the major problems concerning textile wastewater is the treatment of the effluents containing both dyes and surfactants. Biological treatment systems are recommended as useful, economic and eco-friendly methods for treatment of industrial wastewater. The purpose of this study was to investigate the binary removal of a textile dye and a surfactant by growing Aspergillus versicolor culture in molasses medium. The effect of dye and surfactant concentration on the removal of dye and surfactant was determined. This study resulted that 100% of the surfactant and dye molecules removed together with the formation of a dye-surfactant complex by fungus. It is concluded that binary removal systems are very efficient for industrial wastewater treatment.

Sperm retrieval by microdissection testicular sperm extraction and intracytoplasmic sperm injection outcomes in nonobstructive azoospermic patients with Klinefelter syndrome.

Klinefelter syndrome is the most frequent chromosomal abnormality in patients with nonobstructive azoospermia. The development of advanced assisted reproductive techniques, such as testicular sperm extraction and intracytoplasmic sperm injection, has provided the possibility of biological fathering in nonobstructive azoospermic patients with Klinefelter syndrome. We aimed to evaluate our sperm retrieval rate by microdissection testicular sperm extraction and to analyse the intracytoplasmic sperm injection outcomes in these patients. Medical records of 110 nonobstructive azoospermic patients with Klinefelter syndrome were retrospectively reviewed. We found that the sperm retrieval rate by microdissection testicular sperm extraction is lower than published reports on other types of secretory azoospermia. The statistical analyses yielded that age, FSH and testosterone levels as predictive factors for successful sperm retrieval.

Demographical, laboratory and associated findings in patients with perniosis.

BACKGROUND: Perniosis is a cold-induced inflammatory disorder of the acral areas. The objective of this study was to investigate the demographic characteristics, associated factors, clinical and laboratory findings in patients with perniosis and to compare those findings between patients who had recurrent and acute disease. METHODS: Thirty-four patients with perniosis were investigated retrospectively for age, gender, occupation, smoking and diet histories, associated diseases, family history of perniosis, precipitating factors, the month of onset and the duration of perniosis, the distribution of the lesions and the results of laboratory investigations. RESULTS: Fifteen patients were male and 19 were female. The ages of the patients ranged from 15 to 57 years. Thirteen patients were working as sales people, which was the most common occupation. Sixteen patients were smokers. While 25 of the patients had encountered perniosis for the first time, in 9 of the patients, there were recurrent lesions. Diseases other than perniosis were recorded in 6 of the patients. The laboratory tests revealed mild leukopenia in 2, antinuclear antibody (ANA) positivity in 3, mild rise in albumin level in serum protein electrophoresis in 1 patient. ANA positivity was significantly higher in patients with recurrent disease. CONCLUSION: Perniosis was more common in women and below 40 years. We found no significant laboratory findings except ANA positivity in patients with recurrent perniosis.

Sperm retrieval and live birth rates in presumed Sertoli-cell-only syndrome in testis biopsy: a single centre experience.

We aimed to investigate sperm retrieval rates (SRR) by testicular sperm extraction (TESE), factors affecting SRR, and fertilization rate (FR), implantation rate (IR), clinical pregnancy rate (CPR) and live birth rate (LBR) in patients with presumed Sertoli-cell-only syndrome in testis biopsy (SCOS). We retrospectively evaluated files of 134 patients with SCOS who underwent TESE. Group I were patients in whom spermatozoa were retrieved and Group II were patients in whom no spermatozoa could be retrieved. SRR, Follicle stimulating hormone (FSH), Luteinizing hormone (LH), and testosterone levels, and the volume of testicles were compared between groups. In addition, FR, IR, CPR and LBR were determined. Sperm retrieval was achieved in 37 (27.6%) patients (Group I), and the remaining 97 (72.4%) patients made Group II. There were no significant differences in age, infertility time, testicular volume, serum FSH, LH and testosterone levels between Groups I and II (p > 0.05). Intracytoplasmic sperm injection (ICSI) was performed in 36 patients. FR, IR, and CPR were 60.86 ± 23.03, 36.53 ± 41.78 and 51.3% respectively. Cycle and patient based LBRs were 37.8 and 45.1% respectively. SRR in SCOS is lower than patients with non-obstructive azoospermia (NOA) in general. No parameters to predict spermatozoa retrieval were determined. In patients with SCOS, ICSI achieves similar live birth rate to other patients with NOA.

Giant congenital melanocytic naevus associated with Dandy-Walker malformation, lipomatosis and hemihypertrophy of the leg.

A 30-year-old woman presented with congenital hyperpigmented plaques and multiple tumoral lesions. Her left leg was hypertrophic, although the bones were normal. Dermatological examination revealed hyperpigmented macules and plaques with hair on the legs, abdominal and lumbar areas (covering > 60% of the total body surface) and multiple naevi on the face, arms, back and chest. Multiple soft masses of various sizes, some of which colocalized with hyperpigmented plaques, were seen on the trunk and legs. Malignant melanoma was excluded by histopathological examinations of multiple biopsy specimens obtained from the pigmented lesions. Histopathological examination of one of the soft masses showed that it was a lipoma. Cranial magnetic resonance imaging and computed tomography scans showed an enlarged fourth ventricule and vermis hypoplasia (Dandy-Walker malformation; DWM). Neurocutaneous melanosis is a rare combined abnormality of the skin and central nervous system. A few case reports relating to the coexistence of giant congenital melanocytic naevus, lipomatosis and hemihypertrophy have been published in the literature. We report this very rare case of giant melanocytic naevus with lipomatosis, hemihypertrophy of the leg, and DWM.

Homocysteine, vitamin B12 and folic acid levels in psoriasis patients.

BACKGROUND: Hyperhomocysteinaemia is a risk factor for atherosclerotic cardiovascular disease, stroke, peripheral arterial occlusive disease and venous thrombosis. An association between psoriasis and cardiovascular diseases has been reported. AIM: The aim of our study was to examine serum homocysteine, folic acid and vitamin B12 levels in psoriasis patients. MATERIAL AND METHODS: We performed a cross-sectional study in 70 consecutive outpatients with chronic plaque psoriasis and 70 age- and gender-matched controls. Serum levels of homocysteine, vitamin B12 and folic acid levels were measured in both groups. RESULTS: Serum homocysteine, folic acid and vitamin B12 levels did not differ between patient and control groups. In psoriasis patients, homocysteine levels correlated directly with psoriasis severity as measured by psoriasis area and severity index. Serum homocysteine level inversely correlated with serum folic acid levels in the patient group. DISCUSSION: Homocysteine levels correlated with psoriasis area and severity index in the patient group, which shows the disease severity. The increase in cardiovascular mortality with the severity of psoriasis might be also due to the effects of homocysteine.

Temperament and character profile of patients with psoriasis.

BACKGROUND: Psychosocial factors have been implicated as being important in the onset and/or exacerbation of psoriasis.(1) The aim of this study is to examine both the personality factors of patients with psoriasis and the correlations between temperament and character dimensions. MATERIAL AND METHODS: A total number of 105 psoriasis patients and 109 healthy individuals were enrolled in the study. Questionnaires including Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Temperament and Character Inventory (TCI) were administered individually. Both groups were evaluated in terms of depression, anxiety and characteristic features by using these psychological tests and compared statistically. The relationship between psoriasis area and severity index (PASI) score and the BDI, BAI and TCI scales were also evaluated. RESULTS: The mean BDI score of the psoriasis group were significantly higher than the control group. The psoriasis group had significantly higher scores of harm avoidance and lower scores of being self-directedness than the control group. The duration of psoriasis and the PASI scores were not correlated with BDI and BAI scores. CONCLUSION: The current study shows that psoriasis patients have distinctive temperament and character dimensions when compared with the control group. We suggest that evaluation and treatment of psoriasis should also include psychosomatic approaches in clinical practice.

Statin therapy and diabetic skin.

PURPOSE: Statins are widely used drugs for reducing cholesterol levels. The aim of this study was to observe the effects of statin therapy on skin histopathology in both normal and diabetic mice. METHODS: 45 Swiss albino mice were studied in 4 sub-groups: control, statin-treated control, diabetic, and statin-treated diabetic. The first group was diabetic-induced with 250 mg/kg of streptozosin administered intravenously. The second group served as the control. Four weeks after streptozosin injection, both diabetic and control groups were divided into 2 sub-groups and 1 mg/kg/d simvastatin was injected for 14 d intraperitoneally to form the statin-treated control and statin-treated diabetic groups. The remaining 2 groups formed the untreated control and untreated diabetic groups. Histopathological examination of the skin was made with haematoxylin eosin staining under a light microscope. RESULTS: There was no apparent difference between the groups in epidermal thickness, proliferative activity, dermal thickness and composition. Cystic dilatations in the infundibulum of hair follicles with distorted and smaller sebaceous glands were seen in the statin-treated control, diabetic, and statin-treated diabetic groups. CONCLUSION: We conclude that there is altered lipid synthesis in the sebaceous glands in both diabetic and statin-treated groups.
