Genital tuberculosis among infertile women and fertility outcome after antitubercular therapy

Objective

To compare modalities for diagnosing genital tuberculosis (GTB) and to assess fertility outcome after antitubercular therapy (ATT).

Methods

Infertile women underwent endometrial aspiration (EA) and peritoneal washing (PW) for histopathologic examination, PCR, and acid-fast bacilli (AFB) smear and culture of Mycobacterium tuberculosis; laparoscopy and hysteroscopy were also performed. Women with a positive laboratory test and/or laparoscopic finding classified as definitive/probable received ATT for 6 months.

Results

Of 196 women recruited, 187 underwent laparoscopy. Genital tuberculosis was diagnosed in 118 (60.2%). In 41.3%, EA PCR was positive; PW PCR was positive in 7.6%. The remaining laboratory tests were positive in a small number. Laparoscopy indicated definitive GTB in 9.1% and probable GTB in 37.4%. Among the 118 women treated for GTB, 22.9% conceived without in vitro fertilization; of these women, 74.1% had a positive EA PCR and 59.3% had a positive laparoscopy finding. A quarter of the women received ATT solely on the basis of the PCR result and 31.0% of these women conceived.

Conclusion

No single test can detect all instances of GTB. A combination of tests is needed to increase the detection rate. Treatment given solely on the basis of a positive PCR result can result in conception.     

Management of Childhood Brain Tumors: Consensus Report by the Pediatric Hematology Oncology (PHO) Chapter of Indian Academy of Pediatrics (IAP)

Brain tumors are the second most common childhood tumors and remain the leading cause of cancer related deaths in children. Appropriate diagnosis and management of these tumors are essential to improve survival. There are no clinical practical guidelines available for the management of brain tumors in India. This document is a consensus report prepared after a National Consultation on Pediatric Brain Tumors held in Delhi on 06 Nov 2008. The meeting was attended by eminent experts from all over the country, in the fields of Neurosurgery, Radiation Oncology, Pediatric Oncology, Neuropathology, Diagnostic Imaging, Pediatric Endocrinology and Allied Health Professionals. This article highlights that physicians looking after children with brain tumors should work as part of a multidisciplinary team to improve the survival, quality of life, neuro-cognitive outcomes and standards of care for children with brain tumors. Recommendations for when to suspect, diagnostic workup, initial management, long-term follow up and specific management of individual tumors are outlined.     

Non-gynecologic cytology on liquid-based preparations: A morphologic review of facts and artifacts

Liquid-based preparations (LBP) are increasingly being used both for gynecologic (gyn) and non-gynecologic (non-gyn) cytology including fine needle aspirations (FNA). The two FDA-approved LBP currently in use include ThinPrep (TP), (Cytyc Corp, Marlborough, MA) and SurePath (SP), (TriPath Imaging Inc., Burlington, NC). TP was approved for cervico-vaginal (Pap test) cytology in 1996 and SP in 1999 and both have since also been used for non-gyn cytology. In the LBP, instead of being smeared, cells are rinsed into a liquid preservative collection medium and processed on automated devices. Even after a decade of use, the morphological interpretation of LBP remains a diagnostic challenge because of somewhat altered morphology and artifacts or facts resulting from the fixation and processing techniques. These changes include cleaner background with altered or reduced background and extracellular elements; architectural changes such as smaller cell clusters and sheets, breakage of papillae; altered cell distribution with more dyscohesion and changes in cellular morphology with enhanced nuclear features, smaller cell size and slightly more three-dimensional (3-D) clusters. Herein, we review the published literature on morphological aspects of LBP for non-gyn cytology.     

Mothers' understanding of their infants in the context of an internal working model of caregiving

Exploration of mothers' understanding of their infants was guided by the concept of internal working model of caregiving, which includes relationship-relevant expectations and intentions. Twenty-nine mothers of healthy, term infants participated in semistructured interviews concerning actual and hypothetical caregiving episodes. Expectations and intentions were each rated with an ordinal rating (1-6) that qualified adaptiveness or attunement. On average, mothers viewed their infants as having their own agendas and intended to accommodate them within limits. Further specification of expectations and intentions and exploration of conditions that contribute to ordinal types could help researchers and clinicians tailor interventions supportive of maternal development.     

Adaptogenic potential of a polyherbal natural health product: report on a longitudinal clinical trial

Stress is a risk factor for a number of diseases and is an important predictor of health in general. Herbal medicines have been used as adaptogens to regulate and improve the stress response and there is evidence to support the use of herbal medicines for this purpose. We conducted an open-label longitudinal study on the natural health product, OCTA(c), a compound mixture of eight herbs, to determine its effects on perceptions of stress. Eighteen participants were enrolled in the study and were followed over a period of 3 months. Primary endpoints included scores from four validated questionnaires (SF-36v2, PSS, STAI and BDI-II), serum DHEA, ALT, AST and creatinine all measured at 12 weeks. Seventeen patients completed the study. Except for the physical summary score of the SF36 questionnaire, all the subjective scores indicated a highly significant (P < 0.0001) improvement in the participants' ability to cope with stress. No adverse effects were reported and there was no evidence of damage to the liver or kidney based on serum markers. Initial evidence for this polyherbal compound supports its potential as an effective 'adaptogenic' aid in dealing with stress. Further research using a randomized controlled design is necessary to confirm the findings from this pilot study.     

A review of red cell transfusion in the neurological intensive care unit

The treatment of anemia in critically ill patients has changed significantly in the past decade with a major shift toward restrictive blood-transfusion strategy. There is a paucity of studies regarding the approach toward anemia in the neurological critical care population. Anemia is a complex problem in this group of patients because of the extreme sensitivity of brain tissue to changes in the cerebral perfusion pressure and oxygen deficit. Most of the evidence regarding management of anemia and optimal hematocrit threshold is based on animal experiments and observational studies. Recent studies have shown a mixed response in the local oxygen saturations and patient outcomes after blood transfusion in neurological critically ill patients. Although there is little reason to suspect that restrictive transfusion protocols would be detrimental, further studies are needed to determine optimal transfusion threshold in this population.     

Compromised bypass graft outcomes after minimal-incision vein harvest

BACKGROUND: Minimal incision techniques for vein harvest may lessen wound complications after lower extremity revascularization, but long-term patency and limb salvage data are limited. METHODS: This retrospective case-control study used a computerized vascular registry set in an academic vascular surgical practice. All patients undergoing lower extremity revascularization using autogenous reversed great saphenous vein by a single vascular surgeon in a 10-year period were reviewed. Harvest of great saphenous vein via long single incision (SI) in 133 patients was compared with minimal incisions with endoscopy (MIE) in 85, or MI without endoscopy in 106. The main outcome measures were primary and secondary graft patency by Kaplan-Meier life-table analysis and cumulative sum failure (CUSUM). Secondary outcomes of interest were limb salvage and wound complications. RESULTS: No differences were observed between MIE, MI, and SI patients for demographic data, risk factors, or primary indications, including claudication, rest pain, ischemic ulcer, and gangrene. Endoscopic vein harvest patients were significantly more likely than MI or SI to be women and more likely to use tobacco. Primary patency at 5 years was better after SI vein harvest (59%) than with either MI (33%, P = .004) or MIE (44%, P = .045) techniques, although both MI groups had a higher proportion of bypass grafts to the popliteal artery. Similarly, cumulative secondary patency was better after SI (66%) than with MI (47%, P = .045), but not MIE (58%, P = .45). Differences in limb salvage at 5 years in SI (73%) were not statistically superior to either MI (59%, P = .24) or MIE (58%, P = .13). No learning curve for MI or MIE vein grafts was evident by CUSUM for primary patency at 12 months. No differences in wound complication rates were observed for SI (9%), MI (10%), or MIE (6%) grafts (P = .54). CONCLUSIONS: Graft patency and limb salvage deteriorated during the time when MI or MIE techniques of great saphenous vein harvest were adopted. This observation raises concern about the advisability of limiting the extent of the incision at the potential cost of compromised outcomes without an obvious advantage in limiting wound complications.
