Fulltext Mucinous adenocarcinoma arising from chronic perianal fistula

Med J Malaysia, 2006 Mar;61(1):88-90.

Perianal mucinous adenocarcinoma is a rare tumor which may be associated with long-standing chronic perianal sepsis. Early diagnosis is challenging and is based on a high index of clinical suspicion and specific histological features. Definitive treatment is surgical, in the form of an abdomino-perineal resection. We hereby describe a case of a perianal mucinous adenocarcinoma arising from long-standing recurrent perianal fistula and complement this with a brief review of the literature pertaining in particular to the management of this condition.

Fulltext Mucinous adenocarcinoma of the rectum with breast and ocular metastases

Hisham RB, Thuaibah H, Gul YA

Asian J Surg, 2006 Apr;29(2):95-7.

PMID: 16644510

We present the case of a 32-year-old woman who, 10 months after abdominoperineal resection and total mesorectal excision for a locally advanced mucinous adenocarcinoma of the rectum, presented with local recurrence and metastases to the breast, spine, the left eye and orbit. Following surgery, due to the patient's personal reasons, adjuvant chemoradiation was not given. The patient died 2 months later, with disseminated cancer. To the best of our knowledge, breast as well as ocular metastasis in a patient with mucinous adenocarcinoma of the rectum has never been reported and, therefore, needs to be documented.

Ano-coccygeal support in the treatment of idiopathic chronic posterior anal fissure: a prospective non-randomised controlled pilot trial

Idiopathic chronic anal fissure is believed to be a consequence of a traumatic acute anodermal tear followed by recurrent inflammation and poor healing due to relative tissue ischaemia secondary to internal sphincter spasm. This pilot trial compared the efficacy of a novel manufactured ano-coccygeal support attached to a standard toilet seat (Colorec) to the standard procedure of lateral internal sphincterotomy (LIS) for chronic anal fissure.

Fetal heart rate monitoring device using condenser microphone sensor: Validation and comparison to standard devices

BACKGROUND: Fetal heart rate (FHR) monitoring device is highly demanded to assess the fetus health condition in home environments. Conventional standard devices such as ultrasonography and cardiotocography are expensive, bulky and uncomfortable and consequently not suitable for long-term monitoring. Herein, we report a device that can be used to measure fetal heart rate in clinical and home environments.

METHODS: The proposed device measures and displays the FHR on a screen liquid crystal display (LCD). The device consists of hardware that comprises condenser microphone sensor, signal conditioning, microcontroller and LCD, and software that involves the algorithm used for processing the conditioned fetal heart signal prior to FHR display. The device's performance is validated based on analysis of variance (ANOVA) test.

RESULTS: FHR data was recorded from 22 pregnant women during the 17th to 37th week of gestation using the developed device and two standard devices; AngelSounds and Electronic Stethoscope. The results show that F-value (1.5) is less than F𝑐𝑟𝑖𝑡, (3.1) and p-value (p> 0.05). Accordingly, there is no significant difference between the mean readings of the developed and existing devices. Hence, the developed device can be used for monitoring FHR in clinical and home environments.
