Low sexual function and its associated risk factors in pre- and postmenopausal women without clinically significant depression

Objectives

To investigate the low sexual function and its associated risk factors in pre- and postmenopausal women without clinically significant depression.

Methods

Cross-sectional study with 180 women aged between 19 and 60 years who admitted to our outpatient clinic. Sexual function was assessed by female sexual function index and clinically significant depression was measured by Beck depression inventory test.

Results

The rate of low sexual function was 85.9% in postmenopausal (OR 2.9, 95% CI 1.8–4.8) and 47.7% in premenopausal women (OR 0.4, 95% CI 0.3–0.5) (p < 0.0001). The postmenopausal group reported significantly lower desire, arousal, lubrication, orgasm, satisfaction and pain scores than controls (p < 0.0001, for all of them). Low sexual function was positively correlated with age (r = 0.37, p < 0.0001), menopausal status (r = 0.40, p < 0.0001), gravidity (r = 0.44, p < 0.0001), parity (r = 0.43, p < 0.0001), abortion rates (r = 0.27, p = 0.001) and marriage period (r = 0.40, p < 0.0001). There were also significant negative correlations between low sexual function and education (r = −0.39, p < 0.0001) and family income (r = −0.29, p < 0.0001). However, multivariate regression analysis demonstrated that education, family income and menopausal status were the only independent variables for low sexual function after adjusted for age, gravidity, parity, abortion, marriage period and menopausal status.

Conclusion

Low sexual function was relatively high in postmenopausal women without clinically significant depression. Education, family income and menopausal status were the independent risk factors for low sexual function. Investigation of female sexuality was essential for these patients.     

The effects of air pollution and smoking on placental cadmium, zinc concentration and metallothionein expression

This study is designed to determine the placental zinc (Zn) and cadmium (Cd) levels in mothers who were smokers, mothers who were thought to be exposed to air pollution, and mothers who were non-smokers and to investigate the relationship between the expression of placental metallothionein (MT) binding these metals and blood progesterone level. Placental Zn and Cd levels were measured by atomic absorption spectrometry. Presence of placental MT was determined immunohistochemically. Placental changes were examined by light microscope after H&E and PAS staining. Immunohistochemical MT staining of syncytiotrophoblastic and villous interstitial cells were scored as positive or negative. Among the 92 mothers included in the study, 33 were smokers (Group I), 29 had been exposed to air pollution (Group II) and 30 were non-smoker rural residents who had never been exposed to air pollution (Group III). Mean off-spring birth weight of 3198.62+/-380.01 g and mean placenta weight of 561.38+/-111.55 g of Group II were lower when compared with those of other two groups. In Group I, mean placental Cd and Zn were 0.063+/-0.022 microg/g and 39.84+/-15.5 microg/g, respectively, being higher than in other groups. In Group II, mean placental Cd and Zn levels were higher than those of Group III. Blood progesterone levels of subjects in Group I (121 ng/ml) were the lowest of all groups. While the mean count of villi was the highest in Group III; the highest mean count of syncytial knots was in Group II. Thickening of vasculo-syncytial membrane was most prominent in Group I. Similarly, MT staining was positive and very dense in 72.7% (24/33) of cases in Group I (p相似文献   

Comparison of SPECT findings and neuropsychological sequelae in carbon monoxide and organophosphate poisoning

Abnormal regional cerebral blood flow in patients with acute carbon monoxide (CO) and organophosphate (OP) poisoning was examined using (99m)Tc-hexamethylpropylene amine oxime (HMPAO) brain single photon emission computed tomography (SPECT) in fourteen patients. We evaluated the predictive significance of acute phase brain SPECT findings for long-term neuropsychological sequelae. Changes were found in the frontal, temporal, parietal lobes within the first week after both types of poisoning. The distribution of the hypoperfused cerebral areas as demonstrated by (99m)Tc-HMPAO imaging was similar in the two groups during the acute phase. Neuropsychological sequelae developed in five patients poisoned with OP and six with CO. Patients who had SPECT findings heterogeneously or in the temporal or frontal lobes displayed disorientation. Those with fronto-parietal and frontal lobe changes displayed mental confusion. Parkinsonism also was observed in patients with parieto-occipital, parietal and frontal lobe lesions. The distribution of these lesions appears to predict the long term sequelae of these poisonings, though additional studies with larger numbers of patients are needed to confirm the role of SPECT imaging in both OP and CO poisonings.     

Tumours in End-Stage Kidney

Objective

Patients with end-stage kidney disease (ESKD) show a greater risk for renal cell carcinoma (RCC), which tends to be multifocal and bilateral. The malignant potential is unclear. The question is whether to remove both kidneys in patients with a tumor on one side only diagnosed by computed tomography (CT).

Materials and Methods

Kidney tumors were found in 14 patients with ESKD from January 2002 to December 2006. One was unfit for surgery. Thirteen patients underwent nephrectomy and 6 a bilateral procedure of whom only 2 had bilateral tumors on CT, 3 multiple tumors on the contralateral side, and 1 uncontrollable hypertension with tumors as an incidental finding. Tumors were found in all 19 specimens.

Results

In 13 kidneys (68.4%), the tumors were multiple; in 6 (31.6%), solitary. The types of tumor were: 13 (68.4%) papillary RCCs (PRCC), 9 (47.4%) clear RCCs (CRCC), a combination of PRCC and CRCC in 4 (21.0%), and myxoid liposarcoma (with solitary PRCC contralaterally). The mean follow-up was short (19 ± 15 months; maximum, 54 months). Only 1 patient died due to a tumor at 16 months after operation.

Conclusions

There is a high risk for bilateral involvement. Patients who undergo unilateral nephrectomy must be regularly followed and contralateral nephrectomy carefully considered, mainly in transplanted patients on immunosuppression. Further studies are needed to give a definitive answer about the indications for surgery and the indications for contralateral nephrectomy as well. To date, prophylactic contralateral nephrectomy should not be a therapeutic standard.     

FOURNIER'S gangrene: the development of a classical pathology

Necrotizing fasciitis, especially when termed Fournier's gangrene (FG) when it initiates at the perineum, is a rare but rapidly progressive subcutaneous tissue infection characterized by extensive necrosis. Although it has been known for more than a century and considered as a cause of death, the basic medical principles have not changed for many years. We discuss what is new in the evaluation of this enigmatic pathology and speculate about its clinical metamorphosis. We reviewed reports of FG in the English language. The clinical characteristics of FG have been changing; atypical locations of necrotizing fasciitis, e.g. in the head and neck, and the incidence of patients with FG but no predisposing factors, has been increasing. While the role of anaerobic bacteria in FG is decreasing, that of atypical organisms is increasing, and thus hyperbaric oxygen therapy will probably cease to be a common treatment. We think that FG will not be as likely to cause death in future.     

Human immunodeficiency virus infection in a child presenting as herpes zoster ophthalmicus

Herpes zoster is mainly a disease of the elderly. Its occurrence in younger age should be viewed with suspicion. A 9-year-old boy presented with herpes zoster ophthalmicus. He had a history of abdominal surgery one and half years back during which he had received blood transfusion. A year following the surgery he developed general malaise and fever with progressive weight loss. He was treated by local doctors. Subsequently he developed eruptions of blisters around right eye for a duration of 8 days, with which he presented to the department of ophthalmology, Pt JNM Medical College, Raipur. On investigations he was found to have infected with human immunodeficiency virus. Systemic acyclovir along with antiretroviral treatment was started, to which he showed favourable response.
