Maternal & perinatal outcome of fever in pregnancy in the context of dengue - A retrospective observational study

Background & objectives: Pregnant women with dengue infection may be at increased risk of adverse maternal-foetal outcomes. This study was conducted to assess the maternal and perinatal outcomes in women who presented with fever and diagnosed to have dengue infection during pregnancy. Methods: A retrospective observational study was conducted on pregnant women admitted with fever, in a tertiary referral centre in South India, during January 2015 to December 2018. We compared outcomes of women diagnosed with dengue with that of women without dengue. The study outcomes included pre-term birth, stillbirth, low-birth weight (LBW), maternal mortality and thrombocytopenia. Results: During the study period, there were six maternal deaths following complications from dengue infection. Higher rates of thrombocytopenia (24.7% vs. 14.6%, P=0.02) were noted among those with recent dengue infection. The risk of still birth was 2.67 [95% confidence interval (CI) 1.09, 6.57], LBW [risk ratio (RR) 1.13, 95% CI 0.87, 1.45] and pre-term birth (RR 1.33, 95% CI 0.89, 1.97) among the cases. Interpretation & conclusions: Occurrence of adverse maternal and foetal outcomes was increased in pregnant women with fever diagnosed with dengue infection. Future studies are needed to formulate the optimum monitoring and treatment strategies in pregnant women, where dengue can have additive adverse effects to other obstetric complications.

Stability Indicating RP-HPLC Assay Method for Estimation of Dronedarone Hydrochloride in Tablet.

A sensitive and precise high performance liquid chromatographic method has been developed and validated for determination of Dronedarone Hydrochloride. The proposed method was carried out on Analytical HPLC system consisting of Hyperchrome ODS C18 column (250 mm × 4.6 mm, 5μ). The chromatographic separation was achieved using a mobile phase containing acetonitrile: triethylamine buffer (pH-2.3) in the ratio of 70:30 v/v at flow rate of 1.0 mL/min using UV detection at 290 nm. The linear regression analysis data showed good linearity over the concentration range of 10-60μg/mL of dronedarone hydrochloride. The percent assay of dronedarone hydrochloride from tablet was found to be 99.75. The determination of intrinsic stability of the drug was assessed under acidic, alkaline, peroxide, thermal and photolytic stressed conditions. The drug was estimated in presence of its degradation products without interference. The method was validated for accuracy, precision, robustness and recovery studies as per ICH guidelines. The method can be adopted for routine analysis of drug in its tablet formulation.

The 15-Year Evolution of the Thoracoscopic Anterior Release: Does It Still Have a Role?

STUDY DESIGN: Retrospective. PURPOSE: To determine how the indications for anterior thoracoscopic release and fusion have evolved over time. OVERVIEW OF LITERATURE: Anterior release was commonly performed to correct severe spinal deformities before the advent of pedicle screw fixation. The thoracoscopic approach significantly reduced the morbidity, as compared to open thoracotomy procedures. METHODS: We reviewed charts and radiographs of pediatric spinal deformity patients who underwent thoracoscopic release/fusion for their deformity from 1994 to 2008. Indications for the thoracoscopic procedure were assigned to one of the following categories: hyperkyphosis, large/stiff scoliosis, crankshaft prevention, and 'other'. We analysed indications grouped in 3-year intervals to determine how the indications for this procedure evolved over the past 15 years. RESULTS: One hundred and thirty-eight patients (mean age, 15 years; range, 2-28 years) underwent the procedure, with 160 identified indications. The frequency of thoracoscopic anterior release/fusion decreased after peaking in the years 2000-2002. Initially, hyperkyphosis was the most frequent indication (15/33, 45%; 1994-1996), but declined to an intermittent indication since 2006. The use of thoracoscopy to prevent crankshaft has also declined, but remains an indication for the most immature cases (2/17, 12%; 2006-2008). Severe or rigid scoliosis is currently the most common indication for thoracoscopic release/fusion at our center (11/17, 65%; 2006-2008). CONCLUSIONS: The indications for a thoracoscopic anterior release/fusion has evolved with our increased understanding of this procedure and improved posterior fixation with pedicle screw instrumentation. Thoracoscopy in select spinal deformity patients still has an important role despite its less frequent use, as compared to the past decade.

Assessment of Awareness of Diabetic Retinopathy Among the Diabetics Attending the Peripheral Diabetic Clinics in Melaka, Malaysia

In view of the alarming increase in the incidence of diabetes mellitus in Malaysia, we conducted a study to assess the awareness of complications of diabetes among the diabetics attending the peripheral clinics in Melaka. The study period was from January 2007 to December 2007. 351 patients were included in the study. 79.8% were aware of the complications of diabetes mellitus and 87.2% were aware that diabetes can affect the eyes. However, only 50% of the patients underwent an ophthalmological evaluation. Although awareness was good, the motivation to undergo the assessment was poor.

Utility of QuantiFERON TB gold test in a south Indian patient population of ocular inflammation.

Aim: To study the utility of interferon-γ release assays (QuantiFERON TB gold test) in a south Indian patient population of intraocular inflammation. Design: Evaluation of a diagnostic test- a pilot study from January 2007 to October 2008. Materials and Methods: QuantiFERON TB gold test was performed on the following groups of patients following an informed consent. Group A included healthy volunteers without any exposure to tuberculosis (TB) or past history of TB (n=22). Group B included patients with active systemic TB diagnosed by the demonstration of acid-fast bacilli or by the histopathology finding of caseation with granuloma formation from the sputum, lymph node, skin or intestinal biopsies (n=26). Group C included patients with uveitis of known etiologies other than intraocular TB without any history of exposure to active TB (n=21). Group D included patients with a diagnosis of presumed intraocular TB, who responded to antitubercular therapy by decreased or no recurrences following treatment and with a minimum of nine months follow-up following initiation of antitubercular therapy (n=39). Results: The sensitivity and specificity of the QuantiFERON TB gold test to pick up active systemic TB was 58% and 77% respectively. The sensitivity and specificity of the QuantiFERON TB gold test to pickup intraocular TB was 82% and 76% respectively. Conclusions: QuantiFERON TB gold test alone may not be specific for intraocular TB. The significance of this test in a case scenario needs to be interpreted with clinical presentation and other evidences for intraocular TB.

Vision recovery in human immunodeficiency virus-infected patients with optic neuropathy treated with highly active antiretroviral therapy: A case series.

We describe three patients with bilateral, presumed human immunodeficiency virus (HIV)-induced optic neuropathy. The above diagnosis was made by exclusion of infectious agents and neoplasms by detailed clinical and laboratory investigations. All patients had decreased visual acuity, pale optic discs and constriction of visual fields. Improvement was documented in all three patients for visual acuity and in one patient for visual fields following treatment with highly active antiretroviral therapy (HAART). Optic neuropathy in HIV-positive patients does not necessarily carry a poor prognosis even when a treatable cause is not found. This article emphasizes the effectiveness of HAART in presumed HIV-induced optic neuropathy.

A study of the efficacy of endoscopic cyclophotocoagulation for the treatment of refractory glaucomas.

BACKGROUND: Endoscopic cyclophotocoagulation (ECP) is a relatively new method of cyclodestruction which can be used in the management of refractory glaucomas. AIM: To evaluate the safety and efficacy of ECP in the management of refractory glaucomas. SETTINGS AND DESIGN: Prospective interventional non-comparative study. MATERIALS AND METHODS: Fifty eyes of 50 patients with refractory glaucoma, whose intraocular pressures (IOP) were not under control with maximal medical therapy underwent ECP, by the anterior, or pars plana route. IOP, best corrected visual acuity (BCVA), and the number of anti-glaucoma medications, were compared postoperatively to preoperative values. Success was defined as IOP pound 22 mmhg, with or without use of medications. STATISTICAL ANALYSIS USED: Student's t test and repeated measures ANOVA were used to evaluate change in IOP and Student's t test, for comparison of BCVA. Kaplan Meier survival curve was plotted. Wilcoxon signed rank test was used to evaluate reduction in medications. RESULTS: Patients were followed for an average of 12.27 months (3-21months). IOP decreased significantly from 32.58 +/- 9.16 mmHg to 13.96 +/- 7.71 mmHg at last follow-up ( P < 0.001, student's t test). BCVA was significantly improved in the postoperative period ( P < 0.001, student's t test). The average number of antiglaucoma medications decreased from 2.51 +/- 0.97 to 1.09 +/- 1.16 ( P < 0.001, Wilcoxon signed rank test). ECP had a success rate of 82.2%. CONCLUSION: Endoscopic cyclophotocoagulation is an effective procedure in this subset of refractory glaucomas.

Bilateral retinitis following chikun- gunya fever.

A 35-year-old male with a history of chikungunya fever, presented with diminution of vision in the right eye of one-week duration. His best corrected visual acuity (BCVA) was counting fingers 2 meters and 20/20 (Snellens) in the right and left eyes respectively. A diagnosis of neuroretinitis was made in the right eye while left eye showed features of retinitis. ELISA (serum) and polymerase chain reaction (aqueous) were positive for herpes simplex virus. The lesions did not show any response to antiviral or steroid treatment and appeared to be self-limiting. At five months follow-up, lesions had resolved well with BCVA of 20/120 and 20/20 in the right and left eyes respectively.

Uptake of health care services and health status of HIV-infected women diagnosed through antenatal HIV screening in Barbados, 1996-2004 / Utilización de los servicios de atención sanitaria y estado de salud de las mujeres seropositivas al VIH diagnosticadas mediante el tamizaje prenatal para el VIH en Barbados, 1996-2004

OBJECTIVES: To study utilization of HIV-related health care services and to describe the health status of HIV-infected women diagnosed through antenatal voluntary counseling and testing (VCT) for HIV infection in Barbados. METHODS: This is a descriptive study. The study population includes all HIV-infected women in Barbados diagnosed as HIV-infected through VCT for HIV infection during 1996-2004. RESULTS: The median duration of HIV infection from time of diagnosis to the time of this report for the 163 women diagnosed during the study period was 72 months (low range, 9 months; high range, 117 months). Of the 163 women, 102 (62.6 percent) had attended the centralized HIV/AIDS clinic for follow-up (care, treatment, and monitoring), whereas 61 (37.4 percent) had never attended the clinic. The median time lag between diagnosis of HIV infection and first presentation to the HIV/AIDS clinic was 36 months (low range, 1 month; high range, 114 months). Of the HIV-infected women who attended the HIV/AIDS clinic, more than one-fourth had severe immunodeficiency at the time of their first follow-up visit. Of the 53 women undergoing highly active anti-retroviral therapy (HAART) at the time of the study, 23 (43.4 percent) began the therapy within three months of their first follow-up visit. CONCLUSIONS: Early HIV diagnosis through antenatal VCT is not enough to ensure that women with HIV will get adequate and timely HIV-related health care. These women suffer significant premature mortality, largely related to inadequate follow-up.

OBJETIVOS: Estudiar la utilización de los servicios de atención sanitaria relacionados con el VIH y describir el estado de salud de las mujeres infectadas con este virus, diagnosticadas mediante el asesoramiento y la prueba de detección del VIH de carácter voluntario (APDV) durante el período prenatal en Barbados. MÉTODOS: Este es un estudio descriptivo. La población de estudio abarcó a todas las mujeres infectadas por el VIH, diagnosticadas en Barbados mediante el APDV en 1996-2004. RESULTADOS: La mediana de la duración de la infección por el VIH -desde el diagnóstico hasta el momento de este informe- en las 163 mujeres diagnosticadas durante el período de estudio fue de 72 meses (nivel bajo: 9 meses; nivel alto: 117 meses). De las 163 mujeres, 102 (62,6 por ciento) asistieron a la clínica centralizada para el VIH/sida para su seguimiento (atención, tratamiento y monitoreo), mientras que 61 (37,4 por ciento) nunca asistieron a la clínica. La mediana del lapso entre el diagnóstico de la infección por el VIH y la primera presentación a la clínica para el VIH/sida fue de 36 meses (nivel bajo: 1 mes; nivel alto: 114 meses). Más de la cuarta parte de las mujeres infectadas que acudieron a la clínica presentaban inmunodeficiencia grave en el momento de su primera consulta de seguimiento. De las 53 mujeres que se sometieron al tratamiento antirretroviral de gran actividad (HAART) durante el estudio, 23 (43,4 por ciento) comenzaron el tratamiento en los tres meses siguientes a su primera visita de seguimiento. CONCLUSIONES: El diagnóstico temprano mediante el APDV no garantiza que las mujeres con VIH reciban una atención adecuada y oportuna para tratar esa infección. Estas mujeres sufren una mortalidad significativamente prematura, en gran parte debido al inadecuado seguimiento.

A rare case of cellular schwannoma in the pharynx.

Cellular schwannomas in pharyngeal region are rare. These tumors histologically mimic malignant peripheral nerve sheath tumors because of their growth pattern, high cellularity and mitotic activity, but they are relatively benign tumors with a tendency to recur but do not metastasize.

Triple A syndrome with ophthalmic manifestations in two siblings.

Triple A syndrome (Allgrove syndrome) is a rare, autosomal recessive disorder characterized by adrenocorticotropic hormone resistant adrenal insufficiency, alacrima, achalasia of the esophageal cardia, progressive neurological degeneration and occasionally autonomic instability. We report the ophthalmic manifestations in 2 siblings from a consanguineous family with this syndrome. A routine ophthalmic examination showed absence of palpebral portion of lacrimal gland, dry eyes and sluggish pupillary reflexes in both eyes of these patients. Both of these patients had achalasia cardia while the boy additionally had increased serum cortisol levels. Topical ocular lubricants were prescribed for both of them and Heller's cardiomyotomy with fundus plication was done for achalasia. These cases would create an awareness of this rare condition in ophthalmology in addition to suggesting its management.

CD4 cell counts in adults with newly diagnosed HIV infection in Barbados

OBJETIVO: Evaluar los recuentos de células CD4 de toda persona con un diagnóstico reciente de infección por VIH que acudió a la Unidad de Remisión Ladymeade (URL), que es el centro nacional de Barbados para la remisión y el tratamiento de casos de infección por VIH y sida. MÉTODOS: El grupo de estudio se compuso de adultos con infección por VIH en quienes el diagnóstico y la remisión a la URL se habían hecho entre enero y diciembre de 2002. A todos los pacientes remitidos a la URL se les había efectuado un recuento de células CD4 en su primera consulta a la unidad como parte de la serie habitual de pruebas realizadas para determinar en qué estado se encontraba la enfermedad y si había necesidad de administrar antirretrovíricos. RESULTADOS: De los 106 adultos con un diagnóstico reciente, 62 (58,5%) eran varones y tenían una edad mediana de 40 años cuando enfermaron; los otros 44 (41,5%) eran mujeres y tenían una edad mediana de 36 años al enfermar. Casi una quinta parte (18,2%) de las mujeres se encontraban entre los 16 y 25 años de edad, mientras que solamente 8,1% de los varones pertenecían a ese grupo etario. A la mayoría (57,6%) de las personas en el grupo de estudio se les hizo el diagnóstico cuando consultaron por trastornos asociados con la infección por VIH o el sida. En general, el recuento mediano de células CD4 cuando se hizo el diagnóstico fue de 183/µL; 52 de 103 adultos (50,5%) con un diagnóstico reciente de infección por VIH tenían un recuento de células CD4 < 200/µL. En los varones, el recuento mediano de células CD4 fue de 161/µL, y 32 de 60 varones (53,3%)...

Biological characterisation of group F streptococci causing human infections.

Fifty five strains of group F streptococci (GFS) isolated from clinical samples of 53 patients with diverse diseases, were characterised by a battery of physiological tests. Among them 37 (67%) were Streptococcus anginosus F, 14 (25%) were Strep. intermedius, two of which were mannitol positive and 4 (7%) were Strep. constellatus. Determination of minimum inhibitory concentrations of penicillin, erythromycin, ampicillin, gentamicin and cefazolin showed that despite their biochemical heterogeneity, all strains were uniformly susceptible to these antibiotics. Except for bacteraemia, other diseases due to GFS responded well to surgical drainage and/or antibiotics.
