Pediatric sialendoscopy: An 11-year study from a single tertiary care center.

OBJECTIVES: To evaluate the suitability, benefits, and limitations of sialendoscopy for pediatric patients. METHODS: We performed a retrospective analysis of all pediatric sialendoscopy patients (aged 16 years or younger) in our tertiary care institution between September 2007 and October 2018. We characterized patient data, procedure-related factors, complications, and outcomes. RESULTS: In total, 55 sialendoscopies were performed on 42 patients. Among these, 36 were diagnostic endoscopies and 19 were interventional. Five endoscopies were performed under local anesthesia. We identified 16 sialolithiasis patients, where removal of a sialolith was possible in 11 (69%) cases; one case required a second endoscopy. We removed two sialoliths under local anesthesia. Among recurrent juvenile parotitis (RJP) patients, 18/20 (90%) were symptom-free after a single sialendoscopy, and all after a second endoscopy. The median follow-up time was 70 months. We achieved a 95% success rate in sialendoscopies, with a failure-to-treat rate of 15%. The complication rate for the study cohort was 2%, with prolonged parotid swelling the only complication encountered. CONCLUSIONS: Sialendoscopy represented a safe and effective method to treat pediatric patients. Local anesthesia was successful in selected cases, even for sialolith removal. Sialendoscopy had a soothing effect on RJP and the majority of sialoliths were suitable for endoscopic removal.

The study of Wilson disease in pregnancy management.

INTRODUCTION: Pregnancy management in women with Wilson disease (WD) remains an important clinical problem. This research was conducted to investigate how to avoid worsening of WD symptoms during pregnancy and increase pregnancy success in women with WD by identifying the best pregnancy management approaches in these patients. PATIENTS AND METHODS: The clinical data of 117 pregnancies among 75 women with WD were retrospectively analyzed. Related information of the fetus was also recorded and analyzed. At the same time, regression analysis was performed for data of 22 pregnant women without WD, as normal controls. RESULTS: Of a total of 117 pregnancies among the 75 women with WD and 31 pregnancies among the 22 control womenincluded in this study, there were 108 successful pregnancies and 9 spontaneous abortions. Among the 108 successful pregnancies, 97 women a history of copper chelation therapy before pregnancy; all 97 women stopped anti-copper therapy during pregnancy. The nine women with spontaneous abortion had no pre-pregnancy history of copper displacement therapy. The incidence of lower limb edema was higher in the WD group than in normal controls (P = 0.036). Compared with the control group, there was a higher proportion in the WD group of male infants (P = 0.022) and lower average infant birth weight (t = 3.514, P = 0.001). CONCLUSION: It is relatively safe for women with WD patients to become pregnant. The best management method for pregnancy in women with WD may be intensive pre-pregnancy copper chelation therapy and no anti-copper treatment during pregnancy.

Balneotherapy for chronic venous insufficiency.

BACKGROUND: Chronic venous insufficiency (CVI) is a progressive and common disease that affects the superficial and deep venous systems of the lower limbs. CVI is characterised by valvular incompetence, reflux, venous obstruction, or a combination of these with consequent distal venous hypertension. Clinical manifestations of CVI include oedema, pain, skin changes, ulcerations and dilated skin veins in the lower limbs. It can result in a large financial burden on health systems. There is a wide variety of treatment options or therapies for CVI, ranging from surgery and medication to compression and physiotherapy. Balneotherapy (treatments involving water) is a relatively cheap option and potentially efficient way to deliver physical therapy for people with CVI. OBJECTIVES: To assess the efficacy and safety of balneotherapy for the treatment of people with chronic venous insufficiency (CVI). SEARCH METHODS: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, AMED and CINAHL databases, the World Health Organization International Clinical Trials Registry Platform and the Clinical Trials.gov trials register to August 2018. We searched the LILACS and IBECS databases. We also checked references, searched citations and contacted study authors to identify additional studies. SELECTION CRITERIA: We included randomised and quasi-randomised controlled trials comparing balneotherapy with no treatment or other types of treatment for CVI. We also included studies that used a combination of treatments. DATA COLLECTION AND ANALYSIS: Two review authors independently reviewed studies retrieved by the search strategies. Both review authors independently assessed selected studies for complete analysis. We resolved conflicts through discussion. We attempted to contact trial authors for missing data, obtaining additional information. For binary outcomes (leg ulcer incidence and adverse events), we presented the results using odds ratio (OR) with 95% confidence intervals (CI). For continuous outcomes (disease severity, health-related quality of life (HRQoL), pain, oedema, skin pigmentation), we presented the results as a mean difference (MD) with 95% CI. MAIN RESULTS: We included seven randomised controlled trials with 891 participants (outpatients in secondary care). We found no quasi-randomised controlled trials. Six studies (836 participants) evaluated balneotherapy versus no treatment. One study evaluated balneotherapy versus a phlebotonic drug (melilotus officinalis) (55 participants). There was a lack of blinding of participants and investigators, imprecision and inconsistency, which downgraded the certainty of the evidence.For the balneotherapy versus no treatment comparison, there probably was no improvement in favour of balneotherapy in disease severity signs and symptom score as assessed using the Venous Clinical Severity Score (VCSS) (MD -1.66, 95% CI -4.14 to 0.83; 2 studies, 484 participants; moderate-certainty evidence). Balneotherapy probably resulted in a moderate improvement in HRQoL as assessed by the Chronic Venous Insufficiency Questionnaire 2 (CVIQ2) at three months (MD -9.38, 95% CI -18.18 to -0.57; 2 studies, 149 participants; moderate-certainty evidence), nine months (MD -10.46, 95% CI -11.81 to -9.11; 1 study; 55 participants; moderate-certainty evidence), and 12 months (MD -4.99, 95% CI -9.19 to -0.78; 2 studies, 455 participants; moderate-certainty evidence). There was no clear difference in HRQoL between balneotherapy and no treatment at six months (MD -1.64, 95% CI -9.18 to 5.89; 2 studies, 445 participants; moderate-certainty evidence). Balneotherapy probably slightly improved pain compared with no treatment (MD -1.23, 95% CI -1.33 to -1.13; 1 study; 390 participants; moderate-certainty evidence). There was no clear effect related to oedema between the two groups at 24 days (MD 43.28 mL, 95% CI -102.74 to 189.30; 2 studies, 153 participants; very-low certainty evidence). There probably was no improvement in favour of balneotherapy in the incidence of leg ulcers (OR 1.69, 95% CI 0.82 to 3.48; 2 studies, 449 participants; moderate-certainty evidence). There was probably a reduction in incidence of skin pigmentation changes in favour of balneotherapy at 12 months (pigmentation index: MD -3.59, 95% CI -4.02 to -3.16; 1 study; 59 participants; low-certainty evidence). The main complications reported included erysipelas (OR 2.58, 95% CI 0.65 to 10.22; 2 studies, 519 participants; moderate-certainty evidence), thromboembolic events (OR 0.35, 95% CI 0.09 to 1.42; 3 studies, 584 participants; moderate-certainty evidence) and palpitations (OR 0.33, 95% CI 0.01 to 8.52; 1 study; 59 participants; low-certainty evidence), with no clear evidence of an increase in reported adverse effects with balneotherapy. There were no serious adverse events reported in any of the studies.For the balneotherapy versus a phlebotonic drug (melilotus officinalis) comparison, we observed no clear difference in pain symptoms (OR 0.29, 95% CI 0.03 to 2.87; 1 study; 35 participants; very low-certainty evidence) and oedema (OR 0.21, 95% CI 0.02 to 2.27; 1 study; 35 participants; very low-certainty evidence). This single study did not report on the other outcomes of interest. AUTHORS' CONCLUSIONS: We identified moderate- to low-certainty evidence that suggests that balneotherapy may result in a moderate improvement in pain, quality of life and skin pigmentation changes and has no clear effect on disease severity signs and symptoms score, adverse effects, leg ulcers and oedema when compared with no treatment. For future studies, measurements of outcomes such as disease severity sign and symptom score, quality of life, pain and oedema and choice of time points during follow-up must be standardised for adequate comparison between trials.

Identification of vitamin D and other bone metabolism parameters as risk factors for primary bone marrow oedema syndrome.

BACKGROUND: The aetiology and pathogenesis of primary bone marrow oedema syndrome (BMES) remain unclear. This retrospective cross-sectional study in a large cohort of patients with BMES was performed to characterise the overall skeletal status and turnover in patients with BMES, with the aim of identifying risk factors for this disease. METHODS: Patients who were diagnosed with BMES on the basis of clinical and radiological (magnetic resonance imaging) findings in our outpatient clinic were identified retrospectively. Patient history, co-existing metabolic disorders, bone metabolism parameters (serum calcium, phosphate, 25-OH-D3, bone-specific alkaline phosphatase, parathyroid hormone, and osteocalcin, and urinary deoxypyridinoline) and bone mineral density (as measured by dual-energy X-ray absorptiometry) were extracted from the medical records. Patients with secondary causes for BMES were excluded from the study. RESULTS: Of the 171 patients, 65 were identified without secondary cause for BMES. Of the 65 patients, 61.5% were female. The mean age was 49.5 ± 16.7 years, and age-related BMES prevalence showed two peaks, one in adolescence (11-20 years) and one at an older age (51-70 years). BMES predominantly affected the weight-bearing joints, namely, the ankle/foot (55.1%), knee (22.4%) and proximal femur (16.3%). Thyroid disorders and secondary hyperparathyroidism were highly prevalent (21.5 and 21.4%, respectively). On average, the cohort had elevated deoxypyridinoline levels and low 25-OH-D3 levels (19.0 ± 7.5 µg/l in patients without vitamin D supplementation). Osteopenia and osteoporosis were diagnosed in 47.4 and 17.5% of patients, respectively. CONCLUSIONS: BMES is associated with high bone turnover. Patients who are diagnosed with BMES should be screened carefully for bone metabolism disorders and their potential risk factors.

A Comparative Split-Face Trial of Plant-Based Hypoallergenic Ointment vs Petroleum-Based Ointment Following Fractionated Carbon Dioxide Laser Resurfacing of the Face

Purpose: Fractionated carbon dioxide (CO2) laser resurfacing uses fractional photothermolysis with an ablative 10,600-nm wavelength for treatment of rhytides and photodamage. Although associated with reduced side effect profile from traditional ablative lasers, fractionated lasers can lead to significant erythema, edema, crusting, and exudation for 14 days. Post-care includes regular distilled water soaks and healing ointment. This study evaluated efficacy and patient satisfaction of a novel plant-based hypoallergenic ointment (Doctor Rogers RESTORE®Healing Balm; Product 1) compared to petroleum-based lanolin-containing ointment (Aquaphor® Healing Ointment; Product 2) to accelerate wound healing post-laser resurfacing of the face. Design: This was a single-center, prospective randomized, double-blinded, split-face comparative study of 10 subjects with photo-aging and rhytids who received treatment with fractionated CO2 laser between September 2017 and January 2018. Product 1 and Product 2 were randomized to each half of the face and applied from days 0 to 7 with an option to continue to day 14. The primary outcome measures were Investigator-rated degree of erythema, edema, crusting, exudation, and percentage healing, with follow-up evaluations performed at days 2, 4, 7, 14, and 30. The secondary outcome measure was patient satisfaction. Summary: Based on investigator post-resurfacing scores, day 4 showed improved erythema (50%), edema (50%), crusting (40%), and percentage healing (60%) on the Product 1-treated side compared to Product 2, with the majority of remaining patients scoring the same as Product 2. On day 14, Product 1 demonstrated improvement in erythema (50%), edema (30%), and percentage healing (30%) compared to Product 2, with all remaining patients scoring the same as Product 2. Crusting was the same between the two products on day 14. Ninety percent of patients preferred Product 1 over Product 2, found it easier to use, and were more likely to use it in the future. Conclusion: Product 1 is a plant-based hypoallergenic ointment that is safe and effective post-laser treatment and is associated with high patient satisfaction and preference.

Antinuclear Matrix Protein 2 Autoantibodies and Edema, Muscle Disease, and Malignancy Risk in Dermatomyositis Patients.

OBJECTIVE: Dermatomyositis (DM) patients typically present with proximal weakness and autoantibodies that are associated with distinct clinical phenotypes. We observed that DM patients with autoantibodies recognizing the nuclear matrix protein NXP-2 often presented with especially severe weakness. The aim of this study was to characterize the clinical features associated with anti-NXP-2 autoantibodies. METHODS: There were 235 DM patients who underwent testing for anti-NXP-2 autoantibodies. Patient characteristics, including muscle strength, were compared between those with and without these autoantibodies. The number of cancer cases observed in anti-NXP-2-positive subjects was compared with the number expected in the general population. RESULTS: Of the DM patients, 56 (23.8%) were anti-NXP-2-positive. There was no significant difference in the prevalence of proximal extremity weakness in patients with and without anti-NXP-2. In contrast, anti-NXP-2-positive patients had more prevalent weakness in the distal arms (35% versus 20%; P = 0.02), distal legs (25% versus 8%; P < 0.001), and neck (48% versus 23%; P < 0.001). Anti-NXP-2-positive subjects were also more likely to have dysphagia (62% versus 35%; P < 0.001), myalgia (46% versus 25%; P = 0.002), calcinosis (30% versus 17%; P = 0.02), and subcutaneous edema (36% versus 19%; P = 0.01) than anti-NXP-2-negative patients. Five anti-NXP-2-positive subjects (9%) had cancer-associated myositis, representing a 3.68-fold increased risk (95% confidence interval 1.2-8.6) compared to the expected prevalence in the general population. CONCLUSION: In DM, anti-NXP-2 autoantibodies are associated with subcutaneous edema, calcinosis, and a muscle phenotype characterized by myalgia, proximal and distal weakness, and dysphagia. As anti-NXP-2-positive patients have an increased risk of cancer, we suggest that they undergo comprehensive cancer screening.

Allergic rhinitis and voice change.

The aim of this study was to investigate voice function in patients with birch pollen allergy. Voice recordings for acoustic analysis were performed during pollen season and non-pollen season, with 30 patients and 30 controls, and all participants answered a questionnaire about voice symptoms. The results show that the patients reported more voice symptoms than controls during both seasons. In the non-pollen season the symptoms were decreased in the patient group but not in the controls. Speaking fundamental frequency was lower in patients compared to controls during both seasons. The results suggest chronic edema of the vocal folds in the patients. Laryngeal examination with stroboscope was not performed but is recommended for future patients diagnosed with an air-borne allergy.

[Which patients follow the physician's recommendation to take edema-protective agents? : A retrospective, descriptive study]. / Welche Patienten nehmen nach ärztlicher Empfehlung Ödemprotektiva ein? : Eine retrospektive, deskriptive Studie.

BACKGROUND AND OBJECTIVE: Currently little is known about patients taking edema-protective agents against symptoms due to venous diseases. In a survey approximately 7 % of the general population specified taking oral vein drugs. MATERIALS AND METHODS: In a retrospective, descriptive investigation patients of a general practitioner's office, who have orally taken red vine leaf extract (Antistax), were analyzed in terms of age, sex, body mass index (BMI), comorbidities, severity of venous disease, and the concomitant use of compression stockings. RESULTS: The majority of the 82 patients analyzed, taking red vine leaf extract, were female (73 women, 9 men). The average age was 59 years. The BMI was on average 28.3; however, 41 % of the patients had a BMI over 30 and are therefore classified as obese (at least grade I). Of the patients, 52 % were rated clinical stage C2 and 36.5 % stage C3, according to the CEAP classification. Finally, 58 of the 82 patients wore compression stockings in addition to taking their edema-protective drug. CONCLUSIONS: In the present case series edema-protective agents were mainly taken by pre-obese and obese patients in chronic venous insufficiency stages C2 and C3. Oral therapy was combined with compression stockings by 70.7 % of patients.

Vertebral Bone Marrow Edema (VBME) in Conservatively Treated Acute Vertebral Compression Fractures (VCFs): Evolution and Clinical Correlations.

STUDY DESIGN: Prospective observational study. OBJECTIVE: To assess (1) the evolution of vertebral bone marrow edema (VBME) in patients with A1 vertebral compression fractures (VCFs) conservatively treated and (2) the relationship between VBME and clinical symptoms, evaluated as Visual Analogue Scale (VAS) back pain and Oswestry Disability Index (ODI). SUMMARY OF BACKGROUND DATA: VBME is a marker of acute-subacute vertebral fractures. Little is known about the evolution of VBME in conservatively managed VCFs, as well as its clinical meaning. METHODS: 82 thoracic or lumbar VCFs (21 post-traumatic; 61 osteoporotic VCFs), type A1 according to the AOSpine thoracolumbar spine injury classification system, in 80 patients were treated with C35 hyperextension brace for 3 months, bed rest for the first 25 days. Patients with osteoporotic fractures also received antiresorptive therapy and vitamin D supplementation. At 0 (T0), 30 (T1), 60 (T2), and 90 (T3) days, patients underwent magnetic resonance imaging evaluation and clinical evaluation, using VAS for pain and ODI.The paired t test was used to compare changes within groups at each follow-up versus baseline. The unpaired t test after ANOVA (analysis of variance) was used to compare the 2 groups at each follow-up.The association between VBME area, VAS score, and ODI score was analyzed by the Pearson correlation test. The tests were 2-tailed with a confidence level of 5%. RESULTS: A significant VBME mean area, VAS, and ODI scores reduction was recorded at 60 and 90-days follow-ups versus baseline. A positive correlation between VBME reduction and clinical symptoms improvement (VAS and ODI scores improvement) was found in both traumatic and osteoporotic VCFs. CONCLUSION: In benign A1 VCFs conservatively managed, VBME slowly decreases in the first 3 months of magnetic resonance imaging follow-up. This VBME reduction is related to clinical symptoms improvement. LEVEL OF EVIDENCE: 4.

Epidemic dropsy 2013: case series.

Epidemic dropsy (ED) is caused due to intoxication with Argemone mexicana. Here we report a case series of three families, all of whom were residents of Uttar Pradesh, India, who presented in August 2013 with all the classical features of ED. We aim to highlight the importance of this malady even though the sale of unbottled mustard oil is illegal in India.

Dropsy outbreak in a single family in Punjab, India.

Epidemic dropsy is caused by consumption of mustard oil contaminated with argemone oil. It usually occurs in outbreaks with acute manifestation of bilateral pitting edema, erythema, and local tenderness along with cardiac and respiratory problems in severe cases leading to death. We report an outbreak that is unusual because of its gradual onset, clustering in a single family, and with major manifestation of gastrointestinal illness mimicking acute gastroenteritis, hence leading to delayed diagnosis and high mortality. Thus, the diagnosis of epidemic dropsy should be considered as a strong possibility when there is clustering of cases in a single family with on and off gastrointestinal symptoms of vomiting and diarrhea in a mustard oil consuming belt.

Safe refeeding management of anorexia nervosa inpatients: an evidence-based protocol.

OBJECTIVE: Anorexia nervosa is associated with several serious medical complications related to malnutrition, severe weight loss, and low levels of micronutrients. The refeeding phase of these high-risk patients bears a further threat to health and potentially fatal complications. The objective of this study was to examine complications due to refeeding of patients with anorexia nervosa, as well as their mortality rate after the implementation of guidelines from the European Society of Clinical Nutrition and Metabolism. METHODS: We analyzed retrospective, observational data of a consecutive, unselected anorexia nervosa cohort during a 5-y period. The sample consisted of 65 inpatients, 14 were admitted more than once within the study period, resulting in 86 analyzed cases. RESULTS: Minor complications associated with refeeding during the first 10 d (replenishing phase) were recorded in nine cases (10.5%), four with transient pretibial edemas and three with organ dysfunction. In two cases, a severe hypokalemia occurred. During the observational phase of 30 d, 16 minor complications occurred in 14 cases (16.3%). Six infectious and 10 non-infectious complications occurred. None of the patients with anorexia nervosa died within a follow-up period of 3 mo. CONCLUSIONS: Our data demonstrate that the seriousness and rate of complications during the replenishment phase in this high-risk population can be kept to a minimum. The findings indicate that evidence-based refeeding regimens, such as our guidelines are able to reduce complications and prevent mortality. Despite anorexia nervosa, our sample were affected by serious comorbidities, no case met the full diagnostic criteria for refeeding syndrome.

Anterior cruciate ligament injuries in adolescents with open physis: effect of recurrent injury and surgical delay on meniscal and cartilage injuries.

BACKGROUND: Treatment choices for skeletally immature patients sustaining anterior cruciate ligament (ACL) injuries have been controversial. The main dilemma is whether surgical treatment should be provided before patients reach skeletal maturity or whether nonoperative treatment should be provided until the physis has closed. Surgical reconstruction risks physeal damage, while delaying surgery may increase menisci and cartilage damage. PURPOSE: To identify patients at the onset of ACL injury and follow them longitudinally to surgery or final follow-up to describe differences between nonoperative and operative patients and to analyze the effect of delayed reconstruction. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A retrospective review of patients enrolled at a large integrated health care system (IHS) between January 1, 2005, and December 31, 2008, was performed. The study sample included all females ≤12 years old and males ≤14 years old who were evaluated with an ACL injury. The incidence of ACL injuries in each age group was calculated using the number of covered lives by the IHS system per age category as the denominator. Each patient was longitudinally followed using an electronic health record that captures all patient encounters. Every encounter was reviewed for symptoms associated with the index knee, and encounters were considered significant if new-onset pain or swelling was reported. Patients were instructed to restrict their activities while awaiting skeletal maturity to undergo reconstruction by not participating in activities that included any cutting or pivoting movements that would risk injury to the knee. Cartilage and meniscal injuries were recorded for patients who underwent reconstruction. RESULTS: A total of 71 patients were identified during the study period (66 males, 4 females). At the completion of this study, 47 (66.2%) patients had undergone ACL reconstruction, and 24 (33.8%) were being treated nonoperatively. While there were no significant associations between time to surgery and meniscal or cartilage injury, there was a positive association between the number of significant encounters and the likelihood of a combined cartilage and meniscal injury (P = .01). CONCLUSION: This is the first study to measure the incidence of ACL injuries in a skeletally immature population. For patients undergoing ACL reconstruction, an increased number of significant encounters was statistically significantly associated with combined meniscal and cartilage injuries, while increased time from injury to surgery was not significantly associated with additional injuries. In addition, one-third of the patients continued nonoperative treatment without symptoms that warranted surgical interventions during the follow-up period.

Unusual association of epidemic dropsy with brachial neuritis and palatal palsy.

Epidemic dropsy (ED) results from accidental ingestion of adulterated mustard oil with argemone oil. Chief organs involved in this disease are heart, subcutaneous tissue, eyes and kidneys. Nervous system involvement is very rare. Objective manifestation of neurological involvement is even rarer. The authors report two cases from the same family, who were victims of epidemic dropsy along with their parents. One of them showed objective neurologic involvement in the form of brachial neuritis and another showed palatal palsy.

Frequency of symptomatic zinc deficiency in very low birth weight infants.

Current concepts on zinc requirements for premature infants rely on studies dating back more than 20 years. Given that nowadays more premature infants frequently survive we aimed to obtain recent frequency data on zinc deficiency in very low birth weight (VLBW) infants.226 VLBW infants born between July 2005 and December 2009 were retrospectively included in this study. Mean gestational age (GA) was 28.7 weeks (range 23+0 to 38+0) and mean birth weight 1120g (range 354-1495). All infants received zinc supplementation according to the ESPGHAN guidelines. 26 (11.5%) patients showed clinical signs for zinc deficiency of whom 15 had serum zinc concentrations < 50µg/dl, 9 between 50 and 70 µg/dl and 2 > 70 µg/dl. Infants presenting with dermatitis had significantly lower concentrations (mean 26.7 µg/dl, range 19-31) when compared to infants with diarrhoea or isolated peripheral oedema (35.3 µg/dl and 51.8 µg/dl respectively). Strongest independent risk factors were low GA, being small for GA and suffering from intestinal resection due to necrotizing enterocolitis. Frequency of zinc concentrations <50 µg/dl were calculated to be 6.6% in VLBW infants.Even though current guidelines for zinc supplementation were followed the frequency of zinc deficiency was found to be unexpectedly high in ELBW and SGA infants. Despite the retrospective nature of this single centre study, our data strongly suggest that recommendations on zinc supplementation in ELBW and SGA infants should be reviewed.

Case report of a small outbreak of epidemic dropsy.

Epidemic dropsy results from use of edible oils adulterated with Argemone mexicans oil. We report of the disease in a family caused due to sesame oil adulteration. Peculiarity to report this disease is that it occurred due to consumption of contaminated sesame seeds oil instead of mustard oiland secondly epidemic dropsy is also not very common in western Rajasthan. Five members of a family presented to the hospital with history of generalised body swelling, itching and marked cutaneous flush. Few of them also have shortness of breath, dry cough, palpitation, diarrhoea, vomiting and haemoptysis. On physical examination rashes, pallor and signs of cardiac failure were present in few patients. None of them had neurological symptoms and signs. After multiple interviews history of consumption of home made sesame seeds oil was explored in the family and the differential diagnosis of epidemic dropsy was made. Edible oil sample of the sesame seeds oil turned out to be positive for sanguinarine. Sanguinarine and dehydrosanguinarine are two major toxic alkaloids of Argemone oil, which cause widespread capillary dilatation, proliferation and increased capillary permeability. Leakage of the protein-rich plasma component into the extracellular compartment leads to the formation of oedema. There is no specific therapy. Removal of the adulterated oil and symptomatic treatment of congestive cardiac failure and respiratory symptoms, along with administration of anti-oxidants and multivitamins, remains the mainstay of treatment.

Outbreak of epidemic dropsy in Ethiopia: the clinical and therapeutic observation.

INTRODUCTION: Epidemic dropsy results from ingestion of argemone oil contaminated food staffs. The oil from Argemone Mexican seeds contains toxic alkaloids called sanguinarine and dehydrosangunarine. These cause wide spread capillary dilatation, proliferation and leakages. This leads to oedema, hypovolemia and hypotension. OBJECTIVE: To describe the socio-demographic and clinical manifestations of the patients affected with epidemic dropsy in Tikur Anbessa specialized Hospital (TASH). METHODS: A case series study was conducted in an outbreak with unusual cases which was later diagnosed to be epidemic dropsy. Clinical evaluation of suspects was done and optimal therapy given for the complications detected and information was filled in structured format by medical residents and medial chart records review was made for occurrence of new complications in the end of 9 months. RESULTS: A total of 164 patients were seen at TASH from 26 households, in 8 sub-cities of Addis Ababa. A wide range of age group was affected with 70% from 16 to 40 years of age. There was no case among less than 5 years of age. Females were affected more than threefold as compared to males. All the patients manifested with bilateral leg swelling and pitting oedema. It was tender in 50 (30.4%) of them while 43 (26.2%) had erythema. Tachycardia was the next common manifestation occurring in 135 (82.3%), followed by cough in 123 (75%), anaemia in 59 (36%), headache in 58 (35.4%), shortness of breathing in 52 (31.2%), hair loss in 44 (26.8%) and respiratory distress in 35 (21.3%). Abdominal pain, hepatomegally, nausea and vomiting were also seen. There was abnormality in the chest X-ray of 31 (27.2%). Hair loss, tingling and burning extremities, difficulty of standing, hyperpigmentation, pruritic rash and eye symptoms were observed lately during follow up. Five of the patients died while in hospital care due to acute respiratory distress syndrome (ARDS). CONCLUSIONS: The commonest clinical manifestation in our patients is bilateral leg swelling which is similar to other outbreaks of epidemic dropsy elsewhere. The mortality rate is also comparable with other series but all cases died by ARDS in our series which is unusual in other reports. As this is the first reported epidemics in Ethiopia the findings will create awareness of clinical features of epidemic dropsy among clinicians, and therefore, helps for diagnoses of similar problems in the future.

Outbreak investigation of epidemic dropsy in Addis Ababa, Ethiopia:.

BACKGROUND: A 17 year old female patient who presented to a tertiary Hospital in Addis Ababa with bilateral painful leg swelling of two months and shortness of breath, associated with cough and haemoptysis of one week duration was reported to the Ministry of Health and the Addis Ababa Health Bureau. The condition was later detected in 18 individuals from 4 households indicating occurrence of an outbreak of unknown cause in Addis Ababa which lasted during May-July 2008. OBJECTIVE: An outbreak investigation was initiated to identify the cause and prevent further spread, morbidity and mortality. METHODS: Using semi-structured questionnaire, quantitative assessment involving individual cases and affected households was conducted to detect aetiology and risk factors. Unaffected households as well as unaffected members of affected households were also included for comparison purpose. Record review of patients visiting hospitals was also done. Data were collected through house to house visits, and using interview of cases admitted to hospital. Samples of cooking oil were collected for laboratory testing. Data analysis was done using SPSS. RESULTS: A total of 182 patients, 50 (27.5%) males and 132 (72.5%) females, were identified till the outbreak was controlled fully. Age varied from 6-90 years. Death was confirmed in 12 cases, 8 of whom were female. The majority of the patients came from the adjoining Lideta (39.0%) and Kolfe Keranyo (31.9%) subcities. History of illness ranged from less than a week to 12 weeks before presentation. Out of the 106 household members of the 24 affected households identified during the first phase of the investigation, 83 were affected. Most family members who infrequently take meals at home, and children aged 3 years and below were spared. The 21 visited affected households from Kolfe keranyo, Lideta and Bole subcities bought cooking oil produced by a firm in Lideta subcity and all had bought their last supplies in March and April 2008. Samples of cooking food oil taken from this firm and from the affected households were found to have alkaloids of Argemone Mexicana. The number of new cases dropped to zero within 6 weeks after the source was closed. CONCLUSION: The occurrence of bilateral leg swelling in more than one family member of affected households, that bought cooking oil from the same source, sparing the toddlers, and those who infrequently take meals at home, further strengthened by laboratory confirmation of presence of argemone alkaloids in the cooking oil samples taken from the affected households and the common sources led to the diagnosis of the outbreak to be epidemic dropsy.

Laboratory investigation of epidemic dropsy in Addis Ababa, Ethiopia.

BACKGROUND: Food adulteration including adulteration of edible oils may cause serious health problems. One of the most common edible adulterants is argemone oil. An outbreak of epidemic dropsy occurred in Addis Ababa during May-June, 2008. One hundred and eighty two cases were recorded with twelve confirmed deaths. Dietary history of the cases revealed that vegetable oils were the usual cooking medium. OBJECTIVE: The aim of the study was hence to investigate the causes of this outbreak. METHODS: Contaminant identification was done using standard chemical tests, complemented with TLC. Toxicity study was done using Swiss albino mice feed with contaminated and non contaminated standard diet for 30 days. RESULTS: Laboratory investigation of the edible oils has indicated that 47 of the 280 edible oils analyzed were adulterated with argemone oil. About 81% of the edible oil samples collected from Lideta sub-city were adulterated with argemone oil. Toxicological investigation of the adulterated oils also indicated typical features of argemone alkaloid poisoning in mice. CONCLUSION: Results of both laboratory analysis and toxicological studies confirmed consumption of edible oils adulterated with argemone oil as the cause of epidemic dropsy in Addis Ababa.
