Dendritic fibromyxolipoma: A variant of spindle cell lipoma with extensive myxoid change,with cytogenetic evidence

Dendritic fibromyxolipoma (DFML), a rare, recently described distinct benign soft tissue tumor, has many clinicopathological features reminiscent of spindle cell lipoma and solitary fibrous tumor with myxoid change. It is distinguished histologically from both entities by the presence of spindle and stellate cells with dendritic cytoplasmic prolongations, prominent myxoid stroma with abundant keloidal collagen and occasional small plexiform vascular proliferation. We describe a case of histologically confirmed DFML of the left shoulder in a 67‐year‐old male, in which subsequent cytogenetic analysis revealed deletion involving 13q14.3 region in all the tumor cells, typically detected in spindle cell lipoma. In the presence of many clinicopathological similarities between DFML and spindle cell lipoma including chromosomal abnormalities, we postulate that DFML is merely a rare variant of spindle cell lipoma with extensive myxoid degeneration, and may not be considered as a separate entity. The possible differential diagnosis and their distinguishing features are briefly discussed.     

The prevalence of sexual dysfunction and potential risk factors that may impair sexual function in Malaysian women

IntroductionFemale sexual dysfunction (FSD) is a prevalent sexual health problem that does not spare the women in Malaysia, a nation with a conservative multiethnic society.AimTo investigate the prevalence of FSD and the potential risk factors that may impair sexual function among women at a primary care setting in Malaysia.Main Outcome MeasureThe prevalence, the risk factors, and the main predictors for FSD were measured among these women.MethodsA validated Malay version of the Female Sexual Function Index was used to assess FSD. A total of 230 married women aged 18–70 years participated in this study. The sociodemographic and marital profiles of women who had FSD and those who did not were compared; the risk factors for FSD were determined.ResultsThe majority of the respondents were younger than 50 years old, predominantly Malays, and had a higher academic achievement. The prevalence of FSD in the primary care population was 29.6%. The prevalence of women with lack of orgasms, low sexual arousal, lack of lubrication, sexual dissatisfaction, and sexual pain were 59.1%, 60.9%, 50.4%, 52.2%, and 67.8%, respectively.ConclusionThe risk factors for FSD are older age, Malays, married longer (more than 14 years), having less sexual intercourse (less than 1–2 times a week), having more children, married to an older husband (aged >42 years), and having a higher academic status. Lack of lubrication is found to be the main predictor for FSD in this study. Is lack of lubrication a cause or a complication of FSD? Prospective research is needed in the near future.

Platelet-rich plasma with keratinocytes and fibroblasts enhance healing of full-thickness wounds

Advances in tissue engineering led to the development of various tissue-engineered skin substitutes (TESS) for the treatment of skin injuries. The majority of the autologous TESS required lengthy and costly cell expansion process to fabricate. In this study, we determine the possibility of using a low density of human skin cells suspended in platelet-rich plasma (PRP)-enriched medium to promote the healing of full-thickness skin wounds. To achieve this, full-thickness wounds of size 1.767 cm² were created at the dorsum part of nude mice and treated with keratinocytes (2 × 10⁴ cells/cm²) and fibroblasts (3 × 10⁴ cells/cm²) suspended in 10% PRP-enriched medium. Wound examination was conducted weekly and the animals were euthanized after 2 weeks. Gross examination showed that re-epithelialization was fastest in the PRP+cells group at both day 7 and 14, followed by the PRP group and NT group receiving no treatment. Only the PRP+cells group achieved complete wound closure by 2 weeks. Epidermal layer was presence in the central region of the wound of the PRP+cells and PRP groups but absence in the NT group. Comparison between the PRP+cells and PRP groups showed that the PRP+cells-treated wound was more mature as indicated by the presence of thinner epidermis with single cell layer thick basal keratinocytes and less cellular dermis. In summary, the combination of low cell density and diluted PRP creates a synergistic effect which expedites the healing of full-thickness wounds. This combination has the potential to be developed as a rapid wound therapy via the direct application of freshly harvested skin cells in diluted PRP.     

Medical education in Malaysia

Background: Rural general practice in Australia is a challenging clinical discipline that requires specific training. Following a period that saw numbers and skill levels of rural doctors decline, government and professional organizations united to develop a training program that prepares doctors specifically for rural practice.

Summary: This program reflects developments reported in the career choice and education literature, has a curriculum determined by needs analyses, and is delivered predominantly in nonurban centers under the guidance of rural medical educators. Although there is national coordination, different implementation models are being developed in different states to accommodate regional needs.

Conclusions: The vertically integrated and totally nonmetropolitan approach of the North Queensland rural training program is one of the more successful models. This article reviews the early progress toward achieving the goal of improving the rural workforce and discusses probable future developments.

Work and lifestyle factors associated with morbidity of electronic women workers in Selangor,Malaysia

The objective of this study was to identify sociodemographic, work, living arrangement and lifestyle factors associated with morbidity of electronics women workers in selected factories in Selangor, Malaysia. The research design was a cross-sectional questionnaire-based survey. Most of the 401 respondents were young single Malay women. Morbidity was high as 85.5% of the women reported experiencing at least one chronic health problem, and 25.7% said that an illness or injury prevented them from carrying out normal activities within the last two weeks. Major acute illness symptoms were the common cold, backache, and diarrhoea while chronic health problems such as persistent headache, eye problems, menstrual problems, and persistent backache were also reported. After logistic regression, chronic health problems was significantly associated with room sharing; while illness that prevented normal activities within the last two weeks was significantly associated with overtime work and exercise. Further research is recommended to understand the complex inter-relationship between morbidity and working and living conditions.     

Successful transvaginal ultrasound-guided ablation of a cervical pregnancy in a patient with simultaneous intrauterine pregnancy after in vitro fertilization and embryo transfer

Heterotopic pregnancy, or simultaneous intrauterine and extrauterine gestation, is a relatively rare condition. However, induced ovulation and assisted reproductive technologies have markedly increased the incidence of this condition. In this article, a case of heterotopic pregnancy after in vitro fertilization and embryo transfer is presented in which the viable cervical pregnancy was treated by transvaginal ultrasound-guided puncture and injection of potassium chloride in conjunction with methotrexate at week 6 of gestation. At week 12 of gestation, the intrauterine gestation was viable and complete resorption of the cervical pregnancy had occurred. At week 30 of gestation, a healthy baby was delivered by Caesarian section after prelabour rupture of membranes.
