Pregnancy and tuberculosis: to assess tuberculosis cases in pregnancy in a developing region retrospectively and two case reports

Pregnancy and tuberculosis (TB)  To assess TB cases during pregnancy in a developing region retrospectively and to present two case reports. Objectives  Since TB cases activated by HIV infection during pregnancy are well reported in the literature, we aimed to investigate the aggressiveness of pulmonary TB among pregnant women and to assess the effects of TB on the fetus in Kutahya, an area where HIV positive cases are not seen. Materials and methods  The medical records between 2000 and 2005 of the Provincial Health Directorate and Dispensary Against Tuberculosis in Kutahya were reviewed and analyzed retrospectively. Results  Between 2000 and 2005, 667 pulmonary TB cases were examined in the Kutahya region. Of these, 106 occurred in women at reproductive ages between 20 and 44. All were HIV negative cases. In this area, five TB cases were found during pregnancy. There were three cases seen in the first trimester, but pregnancy was ended by curettage. Two women had pulmonary TB and gave birth. Five cases were evaluated as class 1 TB. During and after pregnancy, isoniazid, rifampin, ethambutol, and pyrazinamide (INH + RFP + ETB + PRZ) were used for the treatment. Resistance to anti-TB drugs was not seen during the treatment. Neither congenial nor neonatal TB was seen. Conclusion  Generally, TB is expected to be more aggressive during pregnancy. Since our cases were HIV negative, it can be thought that TB did not progress aggressively. Less aggressiveness and non-resistance to TB treatment in HIV-negative pregnant women compared with HIV-positive women were observed. Therefore, HIV infection results in greater mortality than the triple combination of human immunodeficiency virus, mycobacterium TB, and pregnancy. Besides, the advance of TB in pregnant women was not different from that in non-pregnant women in Kutahya. The fetus and the newborn were not affected. INH, RFP, ETB, and PRZ were used for therapy.     

The correlation of plasma homocysteine with insulin resistance in polycystic ovary syndrome

AIM: This study aims to investigate the existence of any relationship between homocysteine levels and insulin resistance in Turkish women with polycystic ovary syndrome. METHODS: A case-controlled, cross-sectional, observational study was undertaken in a total of 94 infertile Turkish women who required professional help in the Department of Infertility of Dr Zekai Tahir Burak Women's Health Research and Education Hospital. The correlation between serum homocysteine with age, body mass index, hormone profile, fasting insulin and glucose concentrations and insulin resistance were examined in patients with polycystic ovary syndrome and the results were compared to those of women with normal ovaries, who served as a control group. RESULTS: The mean serum fasting glucose and insulin levels, thus insulin resistance index of women with polycystic ovary syndrome, were significantly higher than those of the control subjects. The mean serum homocysteine levels were significantly higher in women with polycystic ovary syndrome than those in the control group. A positive correlation was detected between the mean homocysteine, the insulin resistance index determined by homeostasis model assessment and the fasting insulin levels in polycystic ovary syndrome patients. CONCLUSIONS: Serum homocysteine levels are elevated in women with polycystic ovary syndrome, and this elevation is associated with the serum insulin level rather than androgen excess. The intense treatment of hyperhomocysteinemia in women with polycystic ovary syndrome might improve reproductive outcome and contribute to protection from cardiovascular risks.     

Giant adrenal cyst in a pregnant woman: a case report

In this case report, a rare example of a pregnant woman with a huge adrenal cyst is reported. No other published reports were found to have an outcome like the present case. A 27-year-old primiparous patient admitted to our clinic with complaints of gaining weight, abdominal distension and dyspnea. On physical examination abdominal distension was prominent. She weighed 78 kg. At abdominal ultrasonography, there was an 11 week, single live fetus within the uterine cavity. There was also an approximately 30 x 40 cm sized cyst. The origin of the cyst could not be detected by ultrasonography and magnetic resonance imaging. It was suspected to originate from the ovaries. Tumor markers and other laboratory tests were normal. Laparotomy was planned. During laparotomy, it was observed that there was a huge, thin capsulated cystic lesion filling the abdomen. The uterus and bilateral ovaries were normal. Eleven liters of yellow-colored fluid was drained from the cyst. At exploration, the cyst capsule was originating from a right adrenal lodge and was extirpated. The postoperative weight of the patient decreased to 67 kg. On the third postoperative day, the patient was discharged without any problems. The pathology result of the patient was reported as an epithelial adrenal cyst. The patient did not have any problems on antenatal follow up and had a cesarean delivery at term for cephalopelvic disproportion. A 3500 g, healthy female fetus was delivered.     

Corneal densitometry in patients with arcus senilis and its correlation with serum lipid levels

Purpose:To evaluate corneal densitometry (CD) of patients with arcus senilis (AS) and its association with the serum lipid markers.Methods:This is a cross-sectional, case-control study. The AS diagnosis was made clinically. Forty-five eyes of 45 patients with AS and 38 eyes of 38 age-matched control subjects with no noticeable AS were enrolled in the study. All participants underwent detailed ophthalmologic examination along with corneal Scheimpflug imaging with CD measurement. The evaluated serum lipid markers of the participants included total cholesterol, triglyceride, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and very-low-density lipoprotein (VLDL). The Spearman correlation analysis was used to correlate the serum lipid values and the CD. P < 0.05 was defined as statistically significant.Results:The male to female ratio was 26/19 and 14/24 in the study and control groups, respectively (P = 0.057). The mean age was 59.56 ± 8.7 and 56.47 ± 8.6 years in the study and control groups, respectively (P = 0.117). The mean total CD values in the zones extending from 2 to 12 mm were higher in the study group than in the control group (P < 0.001). The serum HDL level was found to be significantly decreased in the study group compared to the control group (P = 0.048 and Z = −1.976). There was a significant positive correlation between the serum triglyceride level and the CD value of the outermost zone (10–12 mm) (r = 0.334 and P = 0.025).Conclusion:The CD of patients with AS was found to increase not only in the peripheral zone but also in the cornea’s paracentral zone compared to the healthy controls. The serum triglyceride level should give an insight into the intensity of arcus senilis. The serum HDL levels were decreased in patients with AS.     

First imaging results of an intraindividual comparison of 11C-acetate and 18F-fluorocholine PET/CT in patients with prostate cancer at early biochemical first or second relapse after prostatectomy or radiotherapy

Purpose

¹⁸F-Fluorocholine (FCH) and ¹¹C-acetate (ACE) PET are widely used for detection of recurrent prostate cancer (PC). We present the first results of a comparative, prospective PET/CT study of both tracers evaluated in the same patients presenting with recurrence and low PSA to compare the diagnostic information provided by the two tracers.

Methods

The study group comprised 23 patients studied for a rising PSA level after radical prostatectomy (RP, 7 patients, PSA ≤3 ng/ml), curative radiotherapy (RT, 7 patients, PSA ≤5 ng/ml) or RP and salvage RT (9 patients, PSA ≤5 ng/ml). Both FCH and ACE PET/CT scans were performed in a random sequence a median of 4 days (range 0 to 11 days) apart. FCH PET/CT was started at injection (307?±?16 MBq) with a 10-min dynamic acquisition of the prostate bed, followed by a whole-body PET scan and late (45 min) imaging of the pelvis. ACE PET/CT was performed as a double whole-body PET scan starting 5 and 22 min after injection (994?±?72 MBq), and a late view (45 min) of the prostate bed. PET/CT scans were blindly reviewed by two independent pairs of two experienced nuclear medicine physicians, discordant subgroup results being discussed to reach a consensus for positive, negative end equivocal results.

Results

PET results were concordant in 88 out of 92 local, regional and distant findings (Cohen’s kappa 0.929). In particular, results were concordant in all patients concerning local status, bone metastases and distant findings. Lymph-node results were concordant in 19 patients and different in 4 patients. On a per-patient basis results were concordant in 22 of 23 patients (14 positive, 5 negative and 3 equivocal). In only one patient was ACE PET/CT positive for nodal metastases while FCH PET/CT was overall negative; interestingly, the ACE-positive and FCH-negative lymph nodes became positive in a second FCH PET/CT scan performed a few months later.

Conclusion

Overall, ACE and FCH PET/CT showed excellent concordance, on both a per-lesion and a per-patient basis, suggesting that both tracers perform equally for recurrent prostate cancer staging.
