Effectiveness of arginine-containing toothpastes in treating dentine hypersensitivity: a systematic review.

Objectives: To evaluate by way of a systematic review the effectiveness of arginine-containing desensitising toothpastes in comparison to control agents in reducing dentine hypersensitivity.

Data Sources: Electronic databases were searched including: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, LILACS (30/03/2012). Reference lists of eligible studies and systematic reviews were cross-checked in an attempt to identify additional studies.

4-[(4-Meth-oxy-benzene-sulfonamido)-meth-yl]cyclo-hexane-1-carb-oxy-lic acid.

In the title compound, C(15)H(21)NO(5)S, two crystallographically independent mol-ecules are linked into a dimer by a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. In the crystal, mol-ecules are further linked by inter-molecular O-H⋯O hydrogen bonds into a two-dimensional network parallel to (012). Additional stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds.

4-[(4-Methyl-benzene-sulfonamido)-meth-yl]cyclo-hexa-necarb-oxy-lic acid.

The title compound, C(15)H(21)NO(4)S, crystallized with two independent mol-ecules in the asymmetric unit in which the dihedral angles between the mean planes of the benzene and cyclo-hexane rings are 78.3 (2) and 67.6 (2)°.

Women with asymptomatic cervical polyps may not need to see a gynaecologist or have them removed: an observational retrospective study of 1126 cases.

Objectives: (1) To determine the prevalence of pathology in cervical polyps and whether referring and/or removing them is justified, (2) to assess the frequency of associated endometrial pathology and whether investigating the uterine cavity is warranted, and (3) to estimate the financial costs of processing cervical polyps.

Study Design: Retrospective review of the histopathology database and case notes of women who had cervical polyps examined at the pathology department of Ipswich Hospital, UK, over a seven-year period from 01/01/2002 to 31/12/2008.

Results: The number of cervical polyps removed from 988 women was 1126.

Premenopausal bleeding: When should the endometrium be investigated?--A retrospective non-comparative study of 3006 women.

Objective: There is lack of consensus amongst professional organizations as regards the cut-off age for endometrial sampling of premenopausal women presenting with abnormal uterine bleeding (AUB) to exclude endometrial hyperplasia or carcinoma. Therefore we conducted this study to quantify the prevalence of hyperplasia and carcinoma in different age categories in premenopausal women with AUB to identify the appropriate cut-off age for endometrial sampling.

Study Design: A retrospective review of the histopathology reports of endometrial samples taken from 3006 women presenting with AUB and aged from > or =30 to < or =50 years at Ipswich Hospital, UK, from 1 January 1998 to 31 December 2007.
