Thyroid hormones and the thyroxine-binding globulin are increased during hormonal treatment with oral contraceptives without changes in the thyroidal economy. Now we report that even reverse triiodothyronine, the main peripheral catabolite of thyroxine, is significantly increased during therapy with oral contraceptives.

Background: It has been seen that epidemiology and clinical presentation of dengue infection differs significantly across geographical areas. The present study was done to study clinico-hematological profile of patients with dengue fever in Navi Mumbai, Maharashtra.Methods: This prospective observational study was conducted at a tertiary level teaching hospital in Navi Mumbai. All patients were observed over their entire duration of their hospital stay (up to 7 days). We included adult patients of both gender (males or females) who were admitted with clinically and serological diagnosed dengue fever, consenting to participate in the study.  The clinical, laboratory and radiological findings of the patients were noted.Results: All 80 patients presented with fever while 71.25% had myalgia. Retro-orbital pain, rash and vomiting was observed in 38%, 26% and 26% respectively, whereas 23.75% patients were having cough and bleeding from any site. Three fourths of the patients were diagnosed with dengue, 18.75% and 6.25% were diagnosed with DHF and DSS. respectively. Hepatosplenomegaly was increasing from day 1 (9%) to 6th (60%) and 7th (60%) day. Mean haemoglobin levels and haematocrit started increasing from second day onwards, while WBC count and platelet count increased gradually from first day onwards. Splenomegaly was diagnosed in 3.75% of patients while hepatosplenomegaly and fatty liver was observed in 8.75% and 2.5% respectively. There were two deaths, both were cases of DSS.Conclusions: Almost all the patients included in our study showed both haematological and biochemical abnormalities.

Background: Posterior reversible encephalopathy syndrome (PRES), also called the acute hypertensive encephalopathy and reversible leukoencephalopathy syndrome (RPLS), is a clinico-radiological syndrome presents with rapid onset of headache, seizures, loss of consciousness, visual loss and characterized by white matter vasogenic edema affecting parietal and occipital lobes of the brain predominantly. However, the imaging findings are variable and may occur in other locations such as the frontal lobes, thalami, basal ganglia and brainstem. Objective: To study the clinical, imaging spectrum and final disease outcome of PRES Materials And Methods: The study was conducted on 52 patients who presented with clinical features and radiological diagnosis of PRES The clinical, imaging features and outcome of each patient were analyzed Results: The study was conducted on 52 patients with age range from below 10yrs to 65 yrs. Patients presented with various symptoms of which seizures(84.6%) is most common followed by headache(59.6%), vomiting (36.5%), visual disturbances(32.7%), altered sensorium(15.3%), thalamic aphasia (5.7%), hemiparesis(3.8%), paresthesia(3.8%), ataxia(3.8%), Quadriparesis (3.8%) and facial numbness (1.9%) is the least. On MR imaging typical parieto-occipital lobe involvement(98%)is seen in most of the cases, however other atypical regions involved were frontal lobe(52%),temporal lobe (17.3%), cerebellum (27%),thalamus (15.3%), brainstem (13.4%), basal ganglia (9.6%) and corpus callosum (1.9%) Lesions in atypical locations also had lesions in typical locations in all cases except in one case of central PRES. Dominant parieto-occipital pattern was seen in 32%,superior frontal sulcus pattern in 27%,holohemispheric pattern in 34.6%,Partial or asymmetric expression of primary patterns in 5.2% cases Diffusion restriction and postcontrast enhancement was seen in less than 25% cases. Complete resolution of symptoms was seen in 90.5% cases,3.8% of them succumbed to death. On follow up 5.7% of cases showed persistence of symptoms. Conclusion: PRES is a clinico-radiological syndrome with varied clinical and imaging spectrum. Involvement of atypical regions is not uncommon. However lesions in atypical locations often have lesions in typical locations also.Atypical imaging features like restricted diffusion and contrast enhancement are also not uncommon. Knowledge of atypical lesion location, atypical imaging features is necessary for the clinicians and radiologists not to misdiagnose PRES in the appropriate clinical setting
