Comparison of Various Therapeutic Approaches to Manage Infertility in Polycystic Ovarian Syndrome.

OBJECTIVE: To compare the efficacies of common therapeutic regimens and their combinations, used in polycystic ovarian syndrome (PCOS) to improve fertility in reproductive-age women. STUDY DESIGN: A descriptive study. Place and Duration of the Study: Department of Obstetric Gynaecologist, Medicare Cardiac and General Hospital, Karachi, Pakistan, from November 2022 to July 2023. METHODOLOGY: Out of 300 patients with the symptoms of menstrual irregularities and infertility, 152 were diagnosed as PCOS patients based on the ultrasound and hormonal assays and selected for study purpose. They were divided according to their therapeutic regimen into four treatment groups, treated by different therapeutic agents. Group A received metformin 500 mg/day (n = 38); Group B received metformin + myo-inositol 1g (n = 49); Group C received metformin + letrozole 2.5 mg (n = 36), and Group D received metformin + letrozole + myo-inositol (n = 29), orally for three months. All continuous variables, such as body mass index (BMI), FSH, LH, FT4, and FSI were analysed by applying t-test to all therapeutic groups, keeping p ≤0.05 as the level of significance. RESULTS: HCG-positive was found as 86% (n = 33) in Group A, 63% (n = 31) in Group B, 52% (n = 19) in Group C, and 27% (n = 08) in Group D. There were statistically significant (p <0.001) changes in BMI, FSH, LH, FT4, and FSI as well. Metformin alone and metformin plus myo-inositol came out to be more effective than other regimens. CONCLUSION: Metformin alone and myo-inositol plus metformin are effective therapeutic options in PCOS-induced infertility problems. KEY WORDS: Polycystic ovarian syndrome, Infertility, Metformin, Myo-inositol, Letrozole, Menstrual irregularities.

Effect of antidepressants on various periodontal parameters: A case-control study.

BACKGROUND: Various medications are used in the treatment of chronic systemic diseases that affect the periodontium. Antidepressants in mentally depressed patients are prescribed for a long term, but their effect on the periodontium has not been studied adequately. A case-control study was conducted to know the effect of two commonly prescribed antidepressants - venlafaxine (serotonin-norepinephrine reuptake inhibitor [SNRI]) and fluoxetine (selective serotonin reuptake inhibitor [SSRI]). These drugs have been shown to possess anti-inflammatory properties but do not protect the periodontium from insults caused by these medications, which are significantly associated with the presence of destruction of the periodontium. The aim of this study was to clinically evaluate the effect of antidepressants on various periodontal parameters. MATERIALS AND METHODS: The study sample consisted of 182 depressed patients divided into three study groups: Group I - the control group diagnosed as depressed on the first visit, Group II - depressed patients taking fluoxetine 20 mg/day, and Group III - patients taking venlafaxine 75 mg/day. Patients in Groups II and III were on isolated antidepressant medication at least for a period of 3 or more months. Mental depression in patients was assessed with the Patient Health Questionnaire-based Hamilton Depression Rating Scale with scoring of ≤16. All the depressed patients were assessed for periodontal health on the basis of the clinical periodontal parameters. RESULTS: The commonly prescribed antidepressants such as fluoxetine and venlafaxine do not protect the periodontium from destruction in spite of possessing anti-inflammatory properties; therefore, these drugs may be considered as a risk factor for periodontal health. The comparative periodontal indices on nonusers of antidepressants or control group (Group I), users of SSRI (fluoxetine) (Group II), and users of antidepressants-SNRI (venlafaxine) (Group III) showed increased periodontal parameters, especially debris index (DI), calculus index (CI), gingival index (GI), periodontal pocket depth (PD), and loss in clinical attachment level. There was no significant difference for CI and GI, probing PD, and clinical attachment levels except DI which was significantly different (P ≤ 0.001). CONCLUSION: The depressed patients receiving fluoxetine or venlafaxine should be regularly evaluated for periodontal health status as these drugs are risk factors for normal periodontal tissues. Further, these medications did not protect the periodontium from periodontal inflammation, although possessing anti-inflammatory properties.

Use of nitric oxide in thoracic surgery for a high risk cardiac patient.

Nitric oxide (NO) is a selective pulmonary vasodilator especially in the presence of pulmonary artery hypertension. With right ventricle (RV) dysfunction, inhaled NO may increase RV ejection fraction and cardiac output. The main advantage of NO over intravenous therapy is its inability to decrease systemic pressure thereby maintaining the coronary perfusion pressure and the myocardial perfusion. In this case report, we discuss the use of NO in a routine thoracic surgery patient suffering with severe left ventricular dysfunction and a potential candidate for a very high cardiac risk.
