Frequency and severity of musculoskeletal symptoms in humans during an outbreak of trichinellosis caused by Trichinella britovi

Musculoskeletal symptoms such as myalgia are well-known features in the course of trichinellosis; however, the characteristics of musculoskeletal findings have been described in detail in only 1 study. The present study was aimed to determine the joint and muscle symptoms in subjects diagnosed with acute trichinellosis at our rheumatology unit during a Trichinella britovi outbreak that occurred in Izmir, Turkey, in 2004. In total, 98 patients (55 females, 43 males; mean age 32.3 +/- 10.9 yr) were included in the study. A detailed history and full musculoskeletal examination were obtained in each patient. A self-administered questionnaire developed for recording the musculoskeletal symptoms was completed monthly until all the symptoms were resolved. Pain at the joints, restriction of movements (in shoulders, elbows, wrists, knees, ankles, and temporomandibular joints), myalgia, and muscle weakness (neck and shoulder girdle, muscles of the upper and forearm, back, thigh, and calf muscles) were assessed in every patient. Eosinophil counts, serum levels of creatine kinase, and lactate dehydrogenase also were analyzed. The most frequent musculoskeletal symptoms were muscle pain (86 cases [87.8%]), joint pain (83 [84.7%]), subjective muscle weakness (75 [76.5%]), and restriction of joint movements (63 [64.3%]). Calves, upper arm, neck and shoulder girdle, and forearms were the most affected muscle groups. Muscle pain was reported more frequently in the upper than in the lower extremities and during activity. The most frequent painful joints were shoulders, knees, wrists, and ankles. Upper extremity joints were affected more frequently than the lower extremity joints (77.6 vs. 70.4%). Joint pain occurred more frequently at rest. Both muscle weakness and restriction of joint movements were reported in and around the most frequently affected regions. No evidence of arthritis and objective muscle weakness was noted on physical examination in any patient. Musculoskeletal symptoms in the course of T. britovi infection are frequent but with an excellent prognosis. Joint pain in people suffering from acute trichinellosis may occur more frequently than reported previously.     

Clinical and laboratory aspects of a trichinellosis outbreak in Izmir, Turkey

Epidemiological, clinical and laboratory data were collected during an outbreak of trichinellosis, which occurred in Izmir, Turkey, between January and March 2004. The source of the infection was raw meatballs made with a mixture of uncooked beef and pork. Of 474 persons who were admitted at the Ataturk Training and Research Hospital during this period with a history of raw meatball consumption, the diagnosis of trichinellosis was confirmed for 154 (32.5%, 87 males and 67 females; mean age 31 years, range 6-67 years). Among persons with a confirmed diagnosis, 79% had myalgia, 77% weakness and malaise, 63% arthralgia, 40% jaw pain, 68% fever, 63% periorbital and/or facial oedema, 49% oedema at the trunk and limb, 42% abdominal pain, 40% nausea and vomiting, 28% diarrhoea, 23% subconjunctival haemorrhage, 25% macular or petechial rash, 4% subungual haemorrhage, 15% cardiac complaints and 0.2% neurological complaints. Nine patients (5.8%) were hospitalised due to severe myalgia (n = 2), high fever (n = 3), neurological manifestations (n = 1), thrombophlebitis (n = 2) and palmar erythema (n = 1). Eosinophilia was present in 88% of the confirmed cases at the admission. Elevated levels of serum creatine phosphokinase, lactic dehydrogenase and aspartate aminotransferase were detected in 72%, 70% and 16% of the confirmed cases, respectively. The seroconversion occurred in most of the infected people between the 4th and 6th weeks after the infection. All of the confirmed cases were treated with mebendazole. People with severe symptoms were treated also with prednisolone (60 mg/day for three days) and those with a moderately severe clinical pattern received a non-steroid anti-inflammatory drug (naproxen sodium, 550 mg/day). All confirmed cases recovered without any clinical sequela.     

High incidence of hyperandrogenism-related clinical signs in patients with multiple sclerosis

A mild prevalence of multiple sclerosis (MS) is present in females (2:1). To elucidate the pathogenetic role of sex steroids on the disease, we studied 76 women affected by MS, compared to 50 healthy women (mean age +/- SD, 34.9 +/- 0.9 vs. 33.4 +/- 1.7 years). The menarche was at mean age of 12.3 +/- 0.2 vs. 12.4 +/- 0.2. Interval between menses was 28.0 +/- 0.3 vs 27.8 +/- 0.3 days, with duration of menstrual flow of 5.0 +/- 0.2 vs. 5.0 +/- 0.2 days. Oligo- or amenorrhea was present in 20% of patients and in 16% of controls. Oral contraceptives were assumed by 21% of patients and 34% of controls (n.s.). Premenstrual symptoms were found in 43% of patients and in 46% of controls (n.s.). The incidence of hyperandrogenism (greasy skin, acne and hirsutism), evaluated by a specific questionnaire, was higher and statistically significant in MS patients than in controls (28% vs. 10%, p<0.05). Further studies, including a complete clinical and laboratory evaluation of gonadal function, are necessary in order to clarify whether hyperandrogenism may influence MS disease activity.     

TGF-beta1 expression and chronic allograft nephropathy in protocol kidney graft biopsy

Chronic allograft nephropathy (CAN) represents a frequent and irreversible cause of long-term renal graft loss. TGF-beta1 is a key profibrogenic cytokine associated with CAN pathogenesis. Because of clinical diagnostic inaccuracy, protocol biopsy has been suggested to be a beneficial method for early CAN detection. Protocol core biopsy was carried out in 67 consecutive cyclosporine-based immunosuppression-treated kidney transplant recipients with stable renal function 12 months after renal transplantation. Biopsy specimens were analyzed morphologically according to Banff-97' criteria and immunohistologically for TGF-beta1 staining. The data obtained were correlated with plasma TGF-beta1 levels and clinical data. CAN (grade I-III) was found in 51 patients (76 %). CAN grade I was found to be the most frequent one (44 %). A normal finding within the graft was made in only 12 patients (18 %). Clinically silent acute rejection Banff IA was present in 4 patients (6 %). In 8 patients (12 %) with CAN, borderline changes were present. We found a significant correlation between CAN grade and creatinine clearance, as measured by the Cockroft-Gault formula (p<0.01) as well as body mass index (p<0.01). There was a significant correlation between chronic vasculopathy (Banff cv) and creatinine clearance, and between the degree of TGF-beta1 staining and chronic vasculopathy (p<0.01). There were no relations between morphological findings and TGF-beta1 plasma levels, cyclosporine levels, plasma lipids, HLA-mismatches, panel reactive antibodies (PRA), proteinuria, and the donor's age. In conclusion, CAN is a frequent finding in protocol kidney graft biopsies 12 months after transplantation. TGF-beta1 tissue expression is linked with chronic vasculopathy.     

Clinical manifestations in 17 Greek patients with Goldenhar syndrome

Goldenhar (GS) syndrome is a well-recognised developmental disorder involving first and second branchial arches and characterized by considerable phenotypic variability. The present study presents clinical data on the morphologic features, hearing, ophthalmologic, orthopaedic, neurological, cardiovascular, genitourinary and gastrointestinal evaluation of 17 Greek patients (one pair of monozygotic twins) aged 20 days to 23 years with the clinical diagnosis of GS and with a normal karyotype. The most consistent findings were auricular defects (94%), followed by facial (76%) and ocular anomalies (65%), 70% unilateral, mainly right-sided. In the majority of our patients (90%) mandibular hypoplasia was ipsilateral to the dysplastic ear or the most severely affected ear in bilateral cases. Hearing loss, mainly conductive, was noted in 76% of our patients. Skeletal defects were evident in 23%, while cardiovascular, genitourinary and gastrointestinal in 18%, 23% and 12% respectively. The most frequent neurological manifestation was facial nerve paralysis (12%), while the incidence of mental retardation was higher (23%) than reported in the literature, presumably attributed to the severe hearing and vision loss. In a pair of monozygotic twins of our study discordance of clinical findings was noted. Precise evaluation of GS patients and multidisciplinary care management is necessary to avoid possible complications of many systems and to offer appropriate genetic counselling to the family.     

Efficacy of lomustine, teniposide, doxorubicin, bleomycin and prednisone (LTABP) or adriamycin, bleomycin, vinblastine and dacarbazine (ABVD) in the treatment of malignant lymphogranulomatosis resistant to MOPP]

LTABP regimen was applied to 18 patients in IIB and IV stage of malignant lymphogranulomatosis resistant to MOPP. The obtained results were compared with historical control group of 18 patients with similar stage of the disease treated according to ABVD regimen. In both regimens courses were repeated every 28 days or more rarely, when leucopenia and thrombocytopenia prolonged. Only patients who had received at least 3 courses were analysed. In the LTABP group the complete remission was obtained in 10 cases (55%) while partial remission in 6 (33%). In the group treated with ABVD complete remission was obtained in 4 cases (22%) and partial in 9 cases (50%). In the LTABP group 11 patients are still alive and remain in complete remission, while in ABVD group--4 patients. The most frequent side effects in both groups included leucopenia, thrombocytopenia and symptoms of gastrointestinal intolerance. The LTABP regiment allows to obtain higher percentage of the complete remission than ABVD.     

Diagnosis and management of 528 abdominal aortic aneurysms.

Between 1960 and 1979 528 patients with abdominal aortic aneurysms presented to the university department of surgery. Of these, 222 (42%) were elective cases, 72 acute (14%), 174 had ruptured (33%), and four had had a spontaneous aortoduodenal fistula (1%). In all these patients resections were undertaken, but in another 56 patients (11%) the aneurysm was not resected. A review of these cases showed that 91% had symptoms at their first presentation; abdominal pain and backache being most common. The diagnosis could be established in 91% by the presence of pulsatile abdominal mass on clinical examination. The operative mortality for elective resection was 8%, for acute 19%, for ruptured cases 42%, and for spontaneous aortoduodenal fistula 50%. After successful resection the overall five-year survival was 65% by the life table method, and there was no significant difference between elective, acute, and ruptured cases. This five-year survival after resection compares favourably with the expected 76% survival of a similar normal population, and was considerably better than that for conservatively treated patients. As most cases have symptoms, and diagnosis may be established easily by routine physical examination in 91%, the prognosis for this condition could be considerably improved by increased awareness of its existence and early referral for treatment as an elective surgical procedure.     

Comparative efficacy of antigen and antibody detection tests for human trichinellosis

Sera collected from patients with suspected or confirmed exposure to Trichinella spiralis were tested for circulating parasite antigens and antiparasite antibodies. Using an immunoradiometric assay, excretory--secretory antigens from muscle-stage larvae of T. spiralis were detected in the sera of 47% of 62 patients with clinical trichinellosis and 13% of 39 patients without clinical signs but suspected of exposure to infected meat. In comparison, antibodies were detected using an indirect immunofluorescent test in the circulation of 100% of the 62 patients with clinical trichinellosis and 46% of the 39 patients with suspected exposure. The presence of antibodies specific to excretory-secretory products of T. spiralis muscle larvae was confirmed in the majority of the samples tested by a monoclonal antibody-based competitive inhibition assay. These results indicate that antibody detection is a more sensitive diagnostic method for human trichinellosis, but that antigen detection might be a useful confirmatory test because it is a direct demonstration of parasite products in the circulation.     

Failure of diagnosis as a factor in tuberculosis mortality.

In British Columbia between January 1970 and December 1974 active tuberculosis was diagnosed only after death in 69 cases; this was more frequent for miliary tuberculosis (31% of reported cases) than for advanced pulmonary tuberculosis (3% of cases). Although 28% of the patients were more than 75 years old, some were much younger, and 38% of the latter were alcoholics. More than 50% of the patients had been hospitalized before death, for a mean of 14.5 days; they were most frequently thought to have pneumonia or cancer at the time of death. Clearly, increased awareness of the continuing presence of tuberculosis in our society is needed.     

An Outbreak of Trichinellosis by Consumption of Raw Soft-Shelled Turtle Meat in Korea

Trichinellosis transmission to humans via the consumption of reptile meat is rare worldwide. In Korea, however, 2 such outbreaks, possibly via consumption of soft-shelled turtle meat, have occurred in 2 successive years. In 17 August 2014, 6 patients were admitted to Wonju Severance Christian Hospital complaining of myalgia, fever, and headache. Eosinophilia was the indication of the initial laboratory results, and they were eventually diagnosed as trichinellosis by ELISA. All of the patients worked at the same company and had eaten raw soft-shelled turtle meat at a company dinner 10 days prior to their admission. They were treated with albendazole for 2 weeks, upon which all of their symptoms disappeared. This is the 8th report on human trichinellosis in Korea, and the second implicating raw soft-shelled turtle meat.     

Clinical Course,Radiological Manifestations,and Outcome of Pneumocystis jirovecii Pneumonia in HIV Patients and Renal Transplant Recipients

BackgroundPneumocystis jirovecii pneumonia (PCP) is a frequent opportunistic infection in immunocompromised patients. In literature, presentation and outcome of PCP differs between patients with human immunodeficiency virus (HIV) infection and renal transplant recipients (RTRs).MethodsWe conducted a cross-sectional study of patients with PCP based on the HIV and renal transplant registries at our institution. Radiological and clinical data from all confirmed PCP cases between 2005 and 2012 were compared.ResultsForty patients were included: 16 with HIV and 24 RTRs. Radiologically, HIV patients had significantly more areas of diffuse lung affection (81% HIV vs. 25% RTR; p = 0.02), more ground glass nodules 5–10 mm (69% vs. 4%; p = <0.001) and enlarged hilar lymph nodes were found only in HIV patients (44%). Cough and dyspnea were the most common clinical signs (>80%) in both groups. Duration from illness onset to hospital presentation was longer in the HIV patients (median of 18 vs. 10 days (p = 0.02)), implying a less fulminant clinical course. Sixty percent of PCP cases in RTRs occurred >12 months after transplantation. Lengths of hospitalization, admission rates to the intensive care unit, and requirements for mechanical ventilation were similar. Outcome in both groups was favourable.ConclusionsWhile important differences in radiological presentation of PCP between HIV patients and RTRs were found, clinical presentation was similar. PCP only rarely presented with fulminant respiratory symptoms requiring ICU admission, with similar results and outcomes for HIV patients and RTRs. Early diagnosis and treatment is mandatory for clinical success.

Is therapeutic ultrasound effective in treating soft tissue lesions?

Of 76 patients with lateral epicondylitis, 38 were randomly allocated to receive ultrasound treatment and 38 placebo. All 76 were given 12 treatments each over four to six weeks. The conditions of 24 patients (63%) treated with ultrasound and 11 (29%) given placebo improved, the difference being significant at the 1% level. Improvement in particular clinical variables (pain score, weight lifting, grip strength) also showed an advantage for the patients given ultrasound treatment. A simple underwater radiation balance showed considerable fluctuation in ultrasonic output, and frequent checks of output were shown to be necessary. Ultrasound enhances recovery in most patients with lateral epicondylitis.     

Sensitivity to mugwort pollen allergens (Artemisia vulgaris)

The author has found that 42% of patients with pollinosis had positive skin reactions with mugwort (Artemisia vulgaris) pollen allergens. The majority of tested patients (139 out of 187) were also allergic to grass pollens. However, hypersensitivity to mugwort pollen allergens was isolated and did not accompany grass pollen allergy. The symptoms of pollinosis appeared in this group later than in patients sensitive to grass pollen allergens only (over 21 years of age in 71%). Bronchial asthma was diagnosed in 40% of these patients and allergic skin reactions in 25%. Sensitivity to mugwort pollen allergens was accompanied by the sensitivity to pollen allergens of Graminae family of plants in 80% of cases. The author suggests that sensitivity to mugwort pollen allergens is the second most frequent cause of the pollinosis and is diagnosed too rarely. Failures of desensitization in patients sensitive to pollen allergens of Graminae family of plants may often result from coexisting sensitivity to mugwort pollen allergens as this sensitivity produces not only season but perennial clinical symptoms in nearly 50% of patients. The author discusses also botanical relations and cross-reactions in allergy to mugwort and ragweed pollen allergens.     

北京地区住院患儿WU多瘤病毒感染的流行病学研究

自2007年Gaynor A M等人通过高通量测序在肺炎患儿呼吸道样本中发现了WU多瘤病毒(Washington University polyomavirus,WUPyV)以来,WUPyV在世界各地被广泛检出。为了解北京地区急性呼吸道感染住院儿童中WUPyV感染情况及其临床特征,收集北京地区2017年4月至2018年3月共1 276份呼吸道感染住院患儿的鼻咽抽吸物样本,使用real time PCR方法对样本进行WUPyV检测,同时对WUPyV阳性样本进行17种常见呼吸道病毒筛查。共检出WUPyV阳性样本76份(5.96%,76/1 276),4岁以下儿童居多(92.11%,70/76);WUPyV感染全年可见,无显著季节性;多伴随其他呼吸道病毒混合感染(60.53%,46/76),最常见混合感染为鼻病毒和A型流感病毒;WUPyV单一感染者与混合感染者病毒载量无显著性差异,临床诊断和表现基本一致;WUPyV感染患儿的常见诊断为支气管炎(68.42%,52/76)和肺炎(30.26%,23/76);临床症状主要表现为高热、咳嗽、咳痰。研究结果提示WUPyV是北京地区急性呼吸道感染住院患儿呼吸道样本中常见病毒之一,多见于4岁以下儿童。     

Study of dermatophytoses in Lanzarote (1995-199)

We report on the incidence of dermatophytes isolated in Lanzarote island from June-95 to December-99. We gathered 76 samples. Tinea corporis was the most frequent (40.79%) condition, and after this, tinea pedis (26.31%). Trichophyton rubrum was the commonest agent isolated involving 52.63% of patients. We compare our results with other canarian studies, and with clinical patterns described in other spanish studies published in the 1990's. From these comparations we can deduce: a) The distribution of clinical pictures is not homogeneous among the papers, b) tinea corporis etiology is heterogeneous among the series and c) tinea pedis etiology is homogeneous in most of studies. We believe that the comparison by clinical forms avoids any bias due to distribution of clinical forms.     

Revisiting Cushing Syndrome,Milder Forms Are Now a Common Occurrence: A Single-Center Cohort of 76 Subjects

ObjectiveGuidelines recommend initiating testing for Cushing syndrome (CS) based on strong clinical suspicion. Our recent experience suggests the absence of classical stigmata in the majority of patients with CS. We aimed to confirm this premise by revisiting the clinical features of this syndrome in a modern series of patients from a single center.MethodsComputerized records of subjects with CS diagnosed at Tel Aviv Sourasky Medical Center between 2000 and 2018 were reviewed. A Cushing inventory score, including all clinical components of the syndrome, was computed for each subject. Data were compared between the subtypes and evaluated in light of those in the literature.ResultsOf the 76 subjects with CS (60 women/16 men), 49 (64.5%) had Cushing disease; 16 (21.1%), adrenal adenoma; 7 (9.2%), adrenocortical carcinoma; and 4 (5.3%), ectopic adrenocorticotropic hormone secretion. In only 15 of 74 cases (20.3%), clinical suspicion of CS led to testing. Catabolic signs of CS were present in less than 30% of cases. The most common symptom was weight gain (52/67, 77.6%), and the most common comorbidity was hypertension (47/76, 61.8%). There were no differences in the Cushing inventory score between the subtypes. Signs, symptoms, and comorbidities were all significantly less common than in the classical syndrome.ConclusionsModern-day CS presents with subtler features than in the past. Initiating a testing cascade solely based on a strong clinical suspicion may lead to underdiagnosis of milder cases. A concerted effort to devise cost-efficient testing for CS in the current era is needed.     

Cryptococcosis in Colombian children and literature review

Cryptococcosis is reported in adults and is often acquired immune deficiency syndrome (AIDS)-associated; however, its frequency in children is low. Based on the National Survey on Cryptococcosis conducted in Colombia, an epidemiological and clinical analysis was performed on cases of the disease observed in children less than 16 years old between 1993-2010. We found 41 affected children (2.6% prevalence) from the 1,578 surveys received. The country mean annual incidence rate was 0.017 cases/100,000 children under 16 years, while in Norte de Santander the incidence rate was 0.122 cases/100,000 (p < 0.0001). The average age of infected children was 8.4 and 58.5% were male. In 46.3% of cases, a risk factor was not identified, while 24.4% had AIDS. The most frequent clinical manifestations were headache (78.1%), fever (68.8%), nausea and vomiting (65.6%), confusion (50%) and meningeal signs (37.5%). Meningitis was the most frequent clinical presentation (87.8%). Amphotericin B was given to 93.5% of patients as an initial treatment. Positive microbiological identification was accomplished by India ink (94.7%), latex in cerebrospinal fluid (100%) and culture (89.5%). Out of 34 isolates studied, Cryptococcus neoformans var. grubii (VNI 85.3%, VNII 8.8%) was isolated in 94.1% of cases and Cryptococcus gattii (VGII) was isolated in 5.9% of cases. These data are complemented by a literature review, which overall suggests that cryptococcosis in children is an unusual event worldwide.
