A neonate with an anomalous bone attached to the cervical spine

Background contextA digit/rib-like ectopic bone is a rare congenital anomaly that is most commonly seen in the thorax or pelvis. There is a single report of an adult possessing a phalanx-like bone in the cervical region; however, whether the abnormal bone was congenital or acquired remains elusive.PurposeTo elucidate that a phalanx-like bone in the cervical region represents a congenital anomaly.Study designCase report.MethodsReport of the imaging findings in a neonate with a palpable bone projection in the posterior neck.ResultsPlain radiographs demonstrated an ectopic bone posterior to the spinous process of the C5 vertebra. Three-dimensional computed tomography demonstrated that the anomalous bone was attached to the left lamina of the C5 vertebra and that there was abnormal segmentation of the left side of the cervical spine.ConclusionsThe anomalous bone in the neck is a congenital malformation that is accompanied by the maldevelopment of the cervical spine.

Effects of cicletanine on the urinary excretion of prostanoids and kallikrein,and on renal function in man

Summary The effects of cicletanine, a new antihypertensive agent, on the prostaglandin-kallikrein system and the reninangiotensin system were studied. A single oral dose of 200 mg cicletanine or placebo was administered to 9 healthy male volunteers, with samples of blood and urine obtained before and 2 hours after drug administration. Cicletanine increased the urine flow, urinary excretion of sodium, and fractional excretion of sodium by 47%, 115%, and 104%, respectively. While the excretion of 6-keto-prostaglandin-F₁ was enhanced significantly, urinary excretion of thromboxane-B₂, prostaglandin-E₂, and kallikrein were unchanged. Cicletanine also did not alter plasma renin activity, plasma aldosterone concentration, or creatinine clearance. These observations suggest that cicletanine may suppress sodium reabsorption at the nephron, and it may stimulate prostacyclin generation with no effect on that of thromboxane-A₂. Thus cicletanine may be beneficial in the management of cardiovascular disorders in which the equilibrium between prostacyclin and thromboxane is disturbed.     

Laparoscopic ventral rectopexy in patients with fecal incontinence associated with rectoanal intussusception: prospective evaluation of clinical,physiological and morphological changes

Background

Physiological changes after laparoscopic ventral rectopexy (LVR) in patients with rectoanal intussusception (RAI) remain unclear. This study was undertaken to evaluate physiological and morphological changes after LVR for RAI, and to study clinical outcomes following LVR with special reference to fecal incontinence (FI).

Methods

The study was conducted on patients who had LVR for RAI between February 2012 and December 2016 at our institution Patients with RAI and FI were included in the study. Patients with RAI and obstructed defecation and those with RAI and neurologic FI were not included. The patients had anorectal manometry preoperatively, and 3, 6, and 12 months postoperatively. Defecography was performed before and 6 months after the procedure. FI was evaluated using the Fecal Incontinence Severity Index (FISI).

Results

There were 34 patients (median age 77 years (range 60–93) years). Thirty-two patients (94%) were female and the median number of vaginal deliveries was 2 (range 0–5). Neither maximum resting pressure nor maximum squeeze pressure increased postoperatively. There was an overall increase in both defecatory desire volume (median preoperative 75 ml vs. 90 ml at 12 months; p?=?0.002) and maximum tolerated volume (median preoperative 145 ml vs.175 ml at 12 months; p?=?0.002). Postoperatively, RAI was eliminated in all patients but one, although 13 had residual rectorectal intussusception found at defecography. There was an overall reduction in both rectocele size (median preop 29 mm vs. postop 10 mm; p?=?0.008) and pelvic floor descent (median preop 26 mm vs. postop 20 mm; p?=?0.005). Twelve months after surgery, a reduction of at least 50% was observed in the FISI score for 31 incontinent patients (91%).

Conclusions

LVR for RAI produced adequate improvement of FI, and successful anatomical correction of RAI was confirmed by postoperative proctography. Postoperative increase in the rectal volume may have a positive effect on continence.
