Classification of saphenous refluxes: implications for treatment

Objective

To determine the possible correlations of patient age, symptoms and signs with findings of Doppler duplex examination in limbs with varicose veins.

Methods

A total of 2275 ultrasound examinations were done on 2275 limbs of 1751 patients (421 men and 1330 women). Ages ranged from 21 to 94 years (mean 50). Symptoms of aching, heaviness, burning pain (venous neuropathy) were recorded, and signs of ankle hyperpigmentation, scars of healed ulcers and presence of open venous ulcers were noted.

Results

Presence of symptoms was associated with advancing patient age (50.7 vs. 48.8 years). Varicose veins without great saphenous reflux correlated with younger age (43 vs. 53.5 years). Presence of saphenofemoral junctional incompetence correlated with an older age (54.7 vs. 49.8 years), and reflux to the ankle (Hach stage IV) also correlated with older age (mean 63.7 years). A younger age was associated with less advanced signs (C0–C2: 49.1 vs. C4–C6: 60.1 years). Saphenous vein reflux without clinical varices was associated with more advanced signs (C4–C6: 21.3%).

Conclusions

Ageing is associated with advancing clinical symptoms, signs and increasing multifocal reflux in limbs with venous insufficiency. These facts support the concept of early treatment of venous insufficiency before predictable deterioration occurs.

Phase II study of mitoxantrone, leucovorin, and infusional fluorouracil for treatment of metastatic breast cancer

A new combination of mitoxantrone, folinic acid (leucovorin), and infusional fluorouracil (5-FU) was administered to 57 previously treated patients with metastatic breast cancer to evaluate the response rate, response duration, and toxicity of this regimen. Fifty-three patients who received 313 courses of therapy were assessable for response and toxicity. Median age was 48 years (range, 33 to 80 years), and the patients had received an average of 1.5 chemotherapy regimens before this study. Of 53 assessable patients, 24 (45%, or 42% of all entered patients) experienced partial responses (PRs) with a median duration of 6 months (range, 2 to 13 months). Nine (69%) of 13 assessable patients without prior doxorubicin treatment responded, compared with 15 (38%) of 40 with prior doxorubicin (P less than .05). Toxicity was generally mild with dose reductions necessitated more often by mucositis and/or diarrhea than by myelosuppression. One patient with prior high-dose doxorubicin treatment developed congestive heart failure. The combination of mitoxantrone, leucovorin, and infusional 5-FU is an active and well-tolerated regimen for metastatic breast cancer and deserves further evaluation in patients without prior doxorubicin therapy.

Antroduodenal motor effects of intravenous erythromycin in children with abnormalities of gastrointestinal motility

BACKGROUND

The macrolide antibiotic erythromycin (EM) affects gastrointestinal motor activity by acting as agonist of motilin receptors located on the smooth muscle cells of the gastroduodenal tract. We studied the effect of intravenous EM on fasting antroduodenal motility in controls and children with gastrointestinal dysmotility.

METHODS

EM lactobionate (rate, 3.0 mg/kg/h) was infused intravenously while antroduodenal manometry was recorded in 10 controls, in 7 patients with functional dyspepsia and in 6 patients with gut pseudo-obstruction. The mean (SD) age (years) was 5.7 (1.4), 6.5 (2.4), and 6.7 (3.2), respectively. Manometry was performed by means of a four- or six-lumen catheter introduced through the nose and perfused with a low compliance pneumohydraulic system. Five controls received EM and five received saline.

RESULTS

EM, infused 5 minutes after passage of an activity front (AF), induced in controls a premature antroduodenal AF occurring 15.4 +/- 3.2 minutes after starting infusion; no motor changes were seen after saline; duration and propagation velocity of EM-induced AFs did not differ from spontaneous AFs. In patients with functional dyspepsia EM induced various patterns such as premature antroduodenal AFs, antral phase III-like pattern with short duodenal bursts or prolonged phasic antral waves and no duodenal activity. In patients with neurogenic pseudo-obstruction rare or absent antral activity with incoordinated or absent duodenal activity was induced; no contractions were elicited in two patients with myogenic pseudo-obstruction.

CONCLUSIONS

It is confirmed that EM, given at subtherapeutic doses, is a powerful prokinetic agent that can have clinical applications in patients with gastrointestinal dysmotility; however, the effect of the drug seems to be influenced by the nature of the underlying disorder.

Identifying emergency pathology on abdominopelvic CT for non-radiologists

Abdominal and pelvic computed tomography (CT) scans can be complex to interpret but sometimes significant abnormalities are relatively easy to recognize. In emergencies it is beneficial if physicians and surgeons can identify significant pathology that may immediately change patient management. Early image interpretation will allow clinicians to alert radiologists to provide prompt urgent reports, facilitate early referral to other specialities or expedite emergency surgery. This article provides non-radiologists with a systematic approach to identifying emergency pathology on abdominal and pelvic CT scans. It reviews the relevant cross-sectional anatomy and discusses the CT appearances of bowel perforation, bowel obstruction, bowel ischaemia (gangrene), bleeding, appendicitis and hydronephrosis using illustrative examples from the authors' clinical practice. Underlying causes for these conditions and the importance of interpreting the radiological appearances in conjunction with the patient's clinical condition and history are discussed. The authors hope that by using the POGBAH acronym and a systematic approach readers will be able to identify emergency pathology on abdominal and pelvic CT which may improve patient care.

[Tobacco smoking among medical students of the University of Milano, Italy]

In order to evaluate smoking habits among the future medical class an anonymous questionnaire about tobacco smoking was submitted to 822 students of the University of Milano in six academic years, from 1998/99 to 2003/04. A total of 184 students (22.4%) were smoker 463 (56.3%) had never smoked and 161 (19.6%) had previously smoked. More than half of these last had quit smoking during the university years. Smoking habits resulted influenced by the habits in the family (parents and brothers) and among the friends. Anti-smoking campaigns among medical students are needed taking into account their future role in health promotion and in prevention of tobacco smoking and its consequences.

Simultaneous prolonged recordings of proximal and distal intraesophageal pH in children with gastroesophageal reflux disease and respiratory symptoms

OBJECTIVES

To characterize both proximal and distal esophageal acid exposure in children with gastroesophageal reflux-related respiratory disease and to investigate the usefulness of dual-channel intraesophageal pH monitoring in these patients.

METHODS

Continuous simultaneous recording of distal and proximal esophageal pH was performed in 40 patients with gastroesophageal reflux disease and respiratory symptoms (wheezing, nocturnal cough, obstructive bronchitis) (age range 3-168 months) (group A), in 20 patients with reflux disease alone (age range 7-156 months) (group B), and in 14 controls (age range 5-108 months) (group C).

RESULTS

(expressed as median +/- SD) 1) The two groups of patients did not differ with regard to distal and proximal esophageal acid exposure (percentage of reflux) during both the total recording period [distal, A: 9.2 +/- 4, B: 10.7 +/- 7 (NS), C: 1.9 +/- 1.0; and proximal, A: 4.8 +/- 3.3, B: 4.0 +/- 3.3 (NS), C: 1.0 +/- 0.7] and during nighttime [distal, A: 8.0 +/- 6.2, B: 10.4 +/- 6.1 (NS), C: 0.9 +/- 0.65; and proximal, A: 3.72 +/- 3, B: 3.6 +/- 3.0 (NS), C: 0.75 +/- 0.45]. 2) The two groups did not differ with regard to the ratio between proximal and distal esophageal acid exposure during both total and nocturnal periods of analysis. 3) No significant correlation was found between distal and proximal esophageal acid exposure during total and nocturnal recording periods. 4) In patients with reflux-related respiratory disease, the respiratory symptomatic index was significantly higher during distal esophageal acid exposure alone (47.0 +/- 28.6%) than during simultaneous reflux at the two esophageal levels (26.9 +/- 27%) (p < 0.05). Furthermore, reflux episodes associated with respiratory symptoms reached lower pH values than those in patients without symptoms at the two recording sites.

CONCLUSIONS

Gastroesophageal reflux into the proximal esophagus does not discriminate between patients with reflux disease alone and those with reflux disease complicated by respiratory symptoms. Symptoms of asthma in reflux patients appear to be elicited more by a reflex mechanism than by aspiration of gastric refluxate into the airways. Intraesophageal acidification seems to be involved in eliciting respiratory symptoms related to reflux disease, and prolonged intraesophageal two-level pH measurement does not seem to be useful in the approach to patients with reflux disease associated with respiratory symptoms.

Case 339

HISTORY

A 66-year-old male patient with a background history of hypertension and no history of liver disease was found to have mildly deranged liver function test results as part of his annual hypertension review. Clinical examination findings were unremarkable, the patient was afebrile (36.8 °C), and other vital observations were within normal limits. Full blood count and urea and creatinine levels were within normal limits; however, liver function tests revealed a mildly elevated alanine aminotransferase level of 61 IU/L (1.02 µkat/L) (reference range, 0-40 IU/L [0-0.67 µkat/L]), and a mildly elevated γ-glutamyltransferase level of 52 IU/L (0.88 µkat/L) (reference range, 0-50 IU/L [0-0.83 µkat/L]). The patient subsequently underwent US examination of the abdomen, which revealed a large liver lesion in an otherwise normal liver with no imaging features of cirrhosis. MRI of the liver was performed for further characterization (Fig 1). The patient subsequently underwent resection of the large mass and surgical pathology. Surveillance MRI was performed 4 months after surgery (Fig 2).

Small bowel ultrasound: friend or foe?

PURPOSE OF REVIEW

Crohn's disease (CD), requires accurate diagnosis and regular monitoring to manage disease activity, prevent complications, and improve outcomes. Intestinal ultrasound (IUS) has emerged as a noninvasive, real-time imaging modality, offering a valuable alternative to traditional diagnostic techniques such as magnetic resonance enterography (MRE), endoscopy and capsule endoscopy (CE). This review examines recent advances in IUS for the diagnosis and monitoring of small bowel CD, with a focus on its applications, benefits, and limitations.

RECENT FINDINGS

Recent studies have demonstrated that IUS provides high sensitivity and specificity in detecting key markers of disease activity, including bowel wall thickness (BWT), bowel wall flow (BWF), and bowel wall stratification (BWS). Advances in IUS techniques, such as elastography and contrast-enhanced ultrasound (CEUS), have expanded its diagnostic and prognostic capabilities, potentially enabling differentiation between inflammation and fibrosis. However, challenges remain, including operator dependency, variability in scoring systems, and reduced sensitivity for superficial mucosal abnormalities. Efforts to standardize parameters and improve training have shown promise in addressing these limitations.

SUMMARY

IUS is a critical complementary tool for assessing disease activity, transmural healing, and postoperative recurrence in small bowel CD. Its noninvasiveness, cost-effectiveness, and real time assessment make it well suited for routine clinical use. Nonetheless, further multicentre studies are needed to validate scoring systems, optimize integration with other modalities, and improve consistency across clinical settings. IUS holds significant potential for advancing personalized care in small bowel CD, though ongoing research is required to refine its applications and maximize its clinical utility.

Phenotype and Treatment Options for Mesenteric Lymph Node Cavitating Syndrome in Coeliac Disease: A Case Series and Literature Review

Background: There is a paucity of data on mesenteric lymph node cavitation syndrome (MLNCS), a rare condition associated with coeliac disease (CD), characterized by central necrosis within enlarged mesenteric lymph nodes. The largest case series of MLNCS was completed in 1984, (n = 6) and a poor prognosis was identified. Methods: A case series of all patients was conducted with MLNCS treated at the UK NHS England National Centre for Refractory Coeliac Disease between 2000 and 2023. A further literature review was conducted using PubMed and Google Scholar for patients with MLNCS and coeliac disease until 2023. Results: In total, there were 51 patients (6 from our case series and 45 from the literature review); 57% were female, and the mean age was 52.8 years (SD: 14.01 years). The most common presenting symptoms were weight loss (80%) and diarrhea (65%), and patients often had hyposplenism (80%). Persistent villous atrophy was present in 88% of the patients. Ten patients also had Refractory Coeliac Disease. Most of the patients (90%) were on a GFD, but the effect of this is unclear. Treatment with steroids and immunosuppressants resulted in a 40% survival rate. The overall mortality was 43%, associated with cachexia, sepsis, infectious complications, and lymphoma. Conclusions: MLNCS has a poor prognosis, and its diagnosis should prompt further intervention and careful follow-up. Patients commonly present with weight loss and hyposplenism should prompt further investigation. Current treatment options are inadequate and novel therapies are required.
