BACKGROUND AND PURPOSE: Minocycline is under investigation as a neurovascular protective agent for stroke. This study evaluated the pharmacokinetic, anti-inflammatory, and safety profile of minocycline after intracerebral hemorrhage.

METHODS: This study was a single-site, randomized controlled trial of minocycline conducted from 2013 to 2016. Adults ≥18 years with primary intracerebral hemorrhage who could have study drug administered within 24 hours of onset were included. Patients received 400 mg of intravenous minocycline, followed by 400 mg minocycline oral daily for 4 days. Serum concentrations of minocycline after the last oral dose and biomarkers were sampled to determine the peak concentration, half-life, and anti-inflammatory profile.

RESULTS: A total of 16 consecutive eligible patients were enrolled, with 8 randomized to minocycline. Although the literature supports a time to peak concentration (T) of 1 hour for oral minocycline, the T was estimated to be at least 6 hours in this cohort. The elimination half-life (available on 7 patients) was 17.5 hours (SD±3.5). No differences were observed in inflammatory biomarkers, hematoma volume, or perihematomal edema. Concentrations remained at neuroprotective levels (>3 mg/L) throughout the dosing interval in 5 of 7 patients.

CONCLUSIONS: In intracerebral hemorrhage, a 400 mg dose of minocycline was safe and achieved neuroprotective serum concentrations. However, oral administration led to delayed absorption in these critically ill patients and should not be used when rapid, high concentrations are desired. Given the safety and pharmacokinetic profile of minocycline in intracerebral hemorrhage and promising data in the treatment of ischemic stroke, intravenous minocycline is an excellent candidate for a prehospital treatment trial.

Fouda, "Efficacy and safety of two doses of low molecular weight heparin (enoxaparin) in pregnant women with a history of recurrent abortion secondary to antiphospholipid syndrome.", Journal of obstetrics and gynaecology : the journal of the Institute of Obstetrics and Gynaecology, vol. 30, issue 8, pp. 842-6, 2010. Abstract

The aim of this randomised controlled trial was to compare efficacy and safety of two doses of low molecular weight heparin (enoxaparin) in pregnant women with a history of recurrent abortion secondary to antiphospholipid syndrome. A total of 60 women with a minimum of three consecutive abortions before 10 weeks' gestation and positive lupus anticoagulant and/or anticardiolipin antibodies on at least two occasions at least 12 weeks apart were randomised into two groups based on computer generated randomisation list concealed in opaque envelopes. Pregnant women were treated with enoxaparin 40 mg plus low dose aspirin (LDA) (n = 30) or enoxaparin 20 mg plus LDA (n = 30). The live birth rate was 76.67% in enoxaparin 40 mg group and 70% in enoxaparin 20 mg group (p value = 0.559). There were no significant differences between both groups with respect to neonatal outcome, obstetric and maternal complications during pregnancy or puerperium. No cases of severe bleeding, thrombocytopenia or spontaneous fractures were reported in both groups.

BACKGROUND: The aim of this randomized controlled trial was to compare the efficacy of extended letrozole regimen with clomiphene citrate in women with unexplained infertility undergoing superovulation and intrauterine insemination (IUI).

METHODS: Two hundred and fourteen patients with unexplained infertility were randomized into two equal groups using computer generated list and were treated by either letrozole 2.5 mg/day from cycle day 1 to 9 (extended letrozole group, 211 cycles) or clomiphene citrate 100 mg/day from cycle day 3 to 7 (clomiphene citrate group,210 cycles). Intrauterine insemination was performed 36 to 40 hours after HCG administration.

RESULTS: Both groups were comparable with regard to number of mature follicles (2.24 +/- 0.80 Vs 2.13 +/- 0.76) and the day of HCG administration. Serum estradiol was significantly greater in clomiphene citrate group (356 +/- 151 Vs 822 +/- 302 pg/ml, P = < 0.001) and the endometrial thickness was significantly greater in extended letrozole group (9.10 +/- 1.84 Vs 8.18 +/- 1.93 mm, P = < 0.001).The pregnancy rate per cycle and cumulative pregnancy rate were significantly greater in extended letrozole group (18.96% Vs 11.43% and 37.73% Vs 22.86%, respectively).

CONCLUSION: The extended letrozole regimen had a superior efficacy as compared with clomiphene citrate in patients of unexplained infertility undergoing superovulation and IUI.

Fouda, R., H. Ammar, E. Sobhy, and A. M. Amin, "Unusual cause of pericardial effusion.", BMJ case reports, vol. 2012, 2012 Sep 04. Abstract

A 65-year-old Egyptian lady suffering from non-alcoholic liver cirrhosis was referred to our unit for evaluation of a massive pericardial effusion. Few weeks before presentation, she suffered from progressive abdominal distention and dyspnoea. She denied fever, rigors or other cardiorespiratory symptoms. Examination revealed shrunken liver, spleenomegaly and ascites. Chest was clear to auscultation and heart sounds were distant. Chest radiograph showed cardiomegaly and clear lung fields. Abdominal ultrasound confirmed the results of abdominal examination. Transthoracic echocardiogram (TTE) revealed a massive pericardial effusion (PEF) and rheumatic mitral stenosis. Chest tomography showed PEF and clear lung fields. One litre of exudate was removed via TTE-guided needle pericardiocentesis. A pericardio-peritoneal shunt was suspected, which was confirmed via a radioisotopic study. This case is among very few cases that reported PEF in a cirrhotic ascetic patient secondary to a radio-isotopically confirmed pericardio-peritoneal shunt in the literature.

OBJECTIVE: To determine the effectiveness of diclofenac potassium combined with 2% lidocaine gel in reducing the pain of intrauterine device (IUD) insertion.

STUDY DESIGN: We randomized 90 parous women requesting copper T380A IUD insertion in a 1:1 ratio to active or placebo treatment. Active treatment included administration of two 50-mg diclofenac potassium tablets 1h before IUD insertion, application of 3mL of 2% lidocaine gel on the anterior cervical lip 3min before IUD insertion and placement of a cotton swab soaked in 2% lidocaine gel in the cervical canal 3min before IUD insertion. Women in the placebo group received placebo tablets and gel. Participants assessed pain intensity using a 10-cm visual analog scale (VAS). We considered a 2-cm difference in VAS pain score between both groups during IUD insertion to be a clinically significant difference.

RESULTS: Subjects receiving active treatment, as compared to placebo, experienced less pain during tenaculum placement (1.66±0.85 vs. 2.33±1.19, p=.003) and IUD insertion (3.14±0.92 vs. 3.94±1.3, p=.001). Women who delivered only by cesarean section had higher pain scores with IUD insertion compared with women with previous vaginal deliveries (4.41±1.24 vs. 3.29±1.05, p=.001).

CONCLUSION: Diclofenac potassium combined with 2% lidocaine gel slightly reduced pain scores during tenaculum application and copper IUD insertion in parous women; however, the reduction in pain scores lacked clinical significance.

IMPLICATIONS: Although we found a statistically significant lowering of pain scores with pretreatment with diclofenac potassium and lidocaine gel in parous women having copper IUD placement, the reduction is not clinically relevant. These findings may be more relevant for nulliparous women who experience more pain than parous women with IUD insertion and support studies of diclofenac potassium and lidocaine gel in this population.

Fouda, R., H. Ammar, R. Edward, W. M. Alnabawy, and I. M. Fouda, "Tuberculous pericarditis associated with hoarseness of voice due to left recurrent laryngeal nerve paralysis.", BMJ case reports, vol. 2011, 2011. Abstract

A 16-years-old Egyptian girl presented with massive pericardial effusion, fever, weight loss and hoarseness of voice. Laryngoscopy showed left vocal cord paralysis. Chest CT revealed pericardial effusion, amalgamated mediastinal lymph nodes and clear lung fields. Pericardial fluid analysis revealed a lymphocytic exudate with high adenosine deaminase enzyme level, negative stains and cultures for bacteria and fungi. Despite a negative nucleic acid test for tuberculosis; antituberculous and corticosteroids therapies resulted in resolution of pericardial effusion after 3 weeks but hoarseness of voice persisted. Few cases of vocal cord paralysis with tuberculous mediastinal lymphadenopathy were reported in English literature.

Objective: To detect the structural and functional changes of fetal hearts in diabetic pregnancies by using Doppler echocardiography. Methods: This prospective study included 119 pregnant women divided into three groups. Group 1 included 47 pregnant patients with pre-existing diabetes mellitus (DM), group 2 included 40 patients with gestational diabetes and group 3 included 32 non-diabetic pregnant women. M-mode echocardiography was used to measure the thickness of the fetal ventricular walls and interventricular septum. The mitral and tricuspid early (E) and late (A) diastolic velocities and the ventricular shortening fraction were measured. Results: HbA1c % was significantly lower in gestational diabetes group compared with the pre-existing diabetes group. The interventricular septum was significantly thicker in the pre-existing diabetes group compared with other groups. Tricuspid and mitral E/A ratios were significantly lower in the pre-existing diabetes group compared with gestational diabetes and control groups. Moreover, there were no significant differences in the tricuspid and mitral E/A ratios between gestational diabetes group and the control group. The right and left ventricular shortening fractions were similar in the three groups. Conclusion: Fetuses of women with well-controlled gestational diabetes lack the diastolic dysfunction that is present in fetuses of women with pre-existing diabetes
