The treatment strategy for non-functioning pituitary adenomas (NFPA) includes surgery, radiotherapy, medical treatment, or follow-up. Prior series of patients with NFPAs followed without intervention include small numbers of patients with macroadenomas. This study investigated the natural history of patients with macroadenomas followed without treatment.Retrospective cohort study included patients18 years, with a diagnosis of NFPA≥10 mm who were naïve to surgery or medical treatment and followed more than 12 months after diagnosis. Patients with chiasmal threat were excluded. Follow-up terminated if the patient underwent surgery, received cabergoline or was lost to follow-up.Data collected included evaluation of tumor characteristics and size by MRI, symptoms including visual disturbances, and hormonal levels. Tumor growth was defined as maximal diameter increase of2 mm.The cohort included 49 patients (30 males, mean age 68.0±12.0 years). At diagnosis, the average tumor size was 17.8±5.9 mm. Mean follow-up time was 4.9±4.9 years. Increase in tumor size occurred in 16 patients (33%), with an average growth of 5.1±4.4 mm. Reduction in tumor size occurred in 10 patients (20%), with a mean decrease of 3.5±1.3 mm. Twenty-three patients remained with stable tumors. Overall, 33 patients (67%) were observed without any intervention; 3 patients were operated and 13 were treated with cabergoline. None of the parameters including age, gender, baseline tumor size, invasiveness, visual disturbances, or hypopituitarism at diagnosis, predicted tumor growth.Observation of NFPAs without surgery or medical therapy is a reasonable approach in selected patients. In our study, no parameter predicted tumor growth. This article is protected by copyright. All rights reserved.

Purpose:To study the baseline characteristics predicting hypogonadotropic hypogonadism (HH) persistence in men with macroprolactinoma that achieved prolactin normalization.Design:Retrospective cohort study.Methods:Male patients diagnosed with macroprolactinoma and HH that received cabergoline treatment with subsequent prolactin normalization were included: men that achieved eugonadism, and men that remained hypogonadal. Patient’s demographic, clinical and biochemical parameters, sellar imaging and visual fields tests were obtained. Univariate and multivariate models were used to identify predictors of HH persistence.Results:Fifty-eight male patients (age, 49.2±12.6 years) with a median baseline prolactin of 1154 ng/mL (IQR, 478-2763 ng/mL) and adenoma (maximal) diameter of 25.9±14.8 mm were followed for a median of 5.6 years (IQR, 3.0-10.7). Twelve men (21%) suffered from HH persistence at the end of follow-up and 46 men achieved eugonadism. Forty-two out of 46 men (91%) accomplished eugonadism within the first year following prolactin normalization.In a multivariate logistic regression model, hypopituitarism (OR=10.1; 95% CI 1.10 – 101.94), visual field defect (OR=9.9; 95% CI 1.07 – 92.33), and low baseline testosterone levels (OR=0.5; 95% CI 0.29 – 0.93) were independent predictors of HH persistence.Conclusion:In our cohort of men with macroprolactinoma that reached prolactin normalization with cabergoline treatment, 21% had HH persistence. Pituitary hormone deficiency, visual field defects, and low baseline testosterone levels were independently associated with HH persistence. 91% of men achieved eugonadism within the first year following prolactin normalization. These findings may support informed clinical decision-making regarding the initiation of testosterone replacement in men with macroprolactinomas.

The recent global outbreak of the human monkeypox virus was declared a public health emergency by the WHO. Modified Vaccinia Ankara (MVA), provided in a two-dose regimen, is currently the only FDA-approved vaccine against monkeypox virus infection (MPXVi). Nevertheless, many have implemented a single-dose strategy to maximize vaccine supply because of a vaccine shortage. The emergency approval of MVA use for MPXVi was based only on efficacy data from non-human primates. Evidence for the real-life effectiveness of MVA in reducing MPXVi is still warranted. This observational, retrospective cohort study included all members of Clalit Health Services (CHS), eligible for the MVA vaccine on Jul. 31, 2022, when the CHS vaccination campaign was initiated. The rate of MPXVi in participants who received one dose of MVA was compared with that for participants who were not vaccinated. A Cox proportional-hazards regression model with time-dependent covariates was used to estimate the association between vaccination and MPXVi while adjusting for sociodemographic and clinical risk factors. A total of 2,092 subjects met vaccine eligibility criteria. Of those, 1,068 (51%) were vaccinated during the 105 days study period and completed at least 25 days of follow-up. During the study period, 5 infections were confirmed in the vaccinated and 16 infections were confirmed in the unvaccinated participants. The adjusted vaccine effectiveness was estimated at 87% (95% CI: 60%-95%). Our results suggest that a single dose of subcutaneous MVA is associated with a significantly lower risk for MPXVi in high-risk individuals and may contribute to the containment of the current outbreak.

Background The global supply of vaccines against monkeypox virus infection (MPXVi) is significantly lower than demand. Evidence-based vaccine prioritization criteria, based on risk assessment, are essential for fair vaccine distribution. Our objective was to identify the characteristics of individuals at the highest risk for MPXVi. Methods This population-based cohort study included all Clalit Health Services (CHS) subjects assumed to be at risk for MPXVi, based on known characteristics of infected subjects worldwide and insights of LGBTQ+ -specialized CHS clinicians. Cox hazards models were used to identify risk factors for MPXVi in the study cohort. The study commenced on June 6, 2022, the date of the first known MPXVi in CHS patients, until July 31, 2022, when the MPXV vaccination campaign started. Results 8,088 individuals (0.18% of the CHS total population) were identified according to the study inclusion criteria. Of those, 69 (0.85%) were infected during the study period. Risk factors for MPXVi were birth in 1980 or later, history of syphilis, HIV-PrEP use, PDE5 inhibitors use, recent STIs, and registeration to primary healthcare clinics in the Tel-Aviv district. No infections were observed in individuals with none of the factors. Individuals with 3+ risk factors had a 20-fold higher risk for MPXVi compared to those with 0-2, with 85.5% sensitivity and 77.8% specificity. Conclusions Counting the number of validated risk factors per individual seems to provide a robust, simple risk score for MPXVi. Weighting individuals’ risk levels against vaccine availability can assist health systems in the equitable prioritization of vaccine allocation.

Background The recent global outbreak of the human monkeypox virus (MPXV) was declared a public health emergency by the World Health Organization. Modified Vaccinia Ankara (MVA) is currently the only FDA-approved vaccine against MPXV that was approved for this indication based on a study in non-human primates. Since there is currently scarce evidence of the efficacy in humans, our objective was to evaluate real-life vaccine effectiveness (VE) after providing one vaccine dose to individuals at risk of MPVX infection. Methods The study cohort included all Clalit Health Services (CHS) members eligible for the MVA vaccine as defined by the Israeli Ministry of Health. The study commenced on July 31, 2022, when the MVA vaccination campaign was initiated in CHS, and participants were followed until September 12, 2022. A Cox proportional-hazards regression model with time-dependent covariates was used to estimate the association between vaccination and MPXV infections with adjustment for sociodemographic and clinical risk factors. Findings A total of 1,970 subjects met the study eligibility criteria (0.04% of CHS members). Of them, 873 (44%) were vaccinated with MVA and completed at least 25 days of follow-up. 18 infections were confirmed in CHS during the study period, 3 in vaccinated and 15 in unvaccinated status (40.0 versus 6.4 per 100,000 person days). VE was estimated at 79% (95% CI: 24%-94%). Interpretation Our results suggest that a single dose of MVA is associated with a significantly lower risk for MPVX infection in high-risk individuals. These findings highlight that urgent MVA vaccination of high-risk individuals may contribute to the containment of the current MPXV outbreak.

A Cox proportional-hazards regression model with time-dependent covariates was used to estimate the association between vaccination and MPXV infections with adjustment for sociodemographic and clinical risk factors.Results8,168 subjects met the study eligibility criteria (0.17% of CHS members). Of them, 626 (7.7%) were vaccinated with MVA and completed at least 7 days of follow-up. 14 infections were confirmed in CHS during the study period, all within the study cohort and all in unvaccinated participants. VE was estimated at 100% (95% CI: 100%-100%).ConclusionsThese short-term preliminary results suggest a very high VE of a single dose of MVA for MPVX infection in moderate to high-risk individuals. These findings suggest that urgent MVA vaccination of high-risk subjects may contribute to outbreak containment.

OBJECTIVE To study the outcome of men with macroprolactinoma following cabergoline treatment based on tumour size. DESIGN Retrospective cohort study. METHODS The study included 94 men, divided into three groups according to adenoma diameter: 10-19 mm (Group A, n = 36); 20-39 mm (Group B, n = 41); or ≥40 mm (Group C, giant prolactinomas, n = 17). Patients were followed for a mean of 7.5 years with sellar magnetic resonance imaging, visual fields and hormone measurements. RESULTS Mean baseline prolactin was 767, 2090 and 24,806 ng/ml in Groups A, B and C, respectively (p

Objective Patients with acromegaly usually present with the classical signs of acromegaly, whereas patients without the specific signs or symptoms are rarely diagnosed. This unique entity can be named "subclinical acromegaly". Methods This was a retrospective study. Our study group consisted of 8 patients (6 females) with incidentally diagnosed acromegaly, most following head MRI for unrelated reasons and without the specific signs of acromegaly. Results Mean age at diagnosis was 50.1 ± 16.3 years. Baseline IGF-1 ranged between 1.27–2.08 x upper limit of normal (ULN). MRI depicted a pituitary microadenoma in 6 patients, one patient presented with an intrasellar macroadenoma and one had no visible pituitary mass. Mean calculated SAGIT clinical score was 4.6. Three patients underwent trans-sphenoidal resection; two achieved hormonal remission and one improved but did not normalize IGF-1 following surgery. Five patients (including one following surgery) were given somatostatin analogs, and three normalized IGF-1. Several patients improved clinically following treatment, reporting improvement in snoring, hypertension, or weight loss, and pituitary adenoma decreased in size in 2 patients that responded to medical treatment. Conclusions we report a series of 8 patients with very mild and subclinical acromegaly. It is uncertain whether all such patients will gain clinical benefit from treatment, but some experienced clinical improvement due to treatment.

Men with mild to moderate hyperprolactinemia rarely present with normal pituitary on MRI with no visible adenoma, a condition entitled also “idiopathic hyperprolactinemia” or “non-tumoral hyperprolactinemia”. We have characterized a cohort of hyperprolactinemic men with normal pituitary imaging. We have identified 13 men with true hyperprolactinemia and normal pituitary MRI. Baseline clinical and hormonal characteristics and response to medical treatment were retrospectively retrieved from medical records. Mean age at diagnosis was 51 ± 16 years (range, 20–77); mean serum prolactin level at presentation was 91 ng/ml (range, 28–264), eight men presented with low baseline testosterone. Initial complaints leading to diagnosis included sexual dysfunction in ten men and gynecomastia in five. All patients were treated with cabergoline, except for one who was given bromocriptine; none required pituitary surgery. All patients normalized prolactin and testosterone with subsequent clinical improvement reported by most men. Currently, after a mean follow-up of 72 months, ten patients continue treatment with caborgoline (median weekly dose, 0.25 mg), whereas three men discontinued treatment. Men with symptomatic hyperprolactinemia may rarely present with normal pituitary imaging. Medical treatment can lead to hormonal improvement with clinical benefit.

The aim of this study is to assess the benefits of a nurse-led home injection service for somatuline autogel-treated patients with acromegaly, including the adherence to treatment and disease control. Historical prospective data of all patients with acromegaly initiating somatuline autogel between November 14, 2000, and March 9, 2020, who voluntarily enrolled in the nurse-led home injection service between January 1, 2018 and June 30, 2020. Adherence to treatment was calculated as the number of administered injections divided by the number of expected injections during the follow-up period. Excellent adherence to treatment was defined when >90% of scheduled injections were administered, while low adherence was defined when patients received

With the current aging of the world's population, primary hyperparathyroidism (PHPT) is increasingly detected in the elderly. Yet data on the presentation and outcome of PHPT in this group are scarce. The objective was to describe a cohort of patients aged 75 years or more with PHPT observed in our endocrine clinic.A retrospective analysis of medical records in an endocrine clinic at a tertiary hospital. We evaluated 182 patients with PHPT, aged 75 years or more at their last follow-up, all diagnosed at age 65 or more. Laboratory data were compared at diagnosis and last follow-up.Mean age at diagnosis was 73 ± 4 years, last follow-up was at 83 ± 4 years, and mean follow-up was 11.3 ± 5.5 years. Osteoporosis, fractures, and nephrolithiasis were diagnosed in 114(63 %), 84(46 %), and 43(24 %) patients, respectively. Overall, 150 patients had an indication for surgery; of them, the 29 who underwent parathyroidectomy were younger than the non-operated patients and had higher rates of hypercalciuria. During the follow-up of the 141 patients who did not undergo operation, serum and urinary calcium levels significantly had decreased, and vitamin D level had increased at last visit (10.4 ± 0.5 mg/dl, 161 ± 70 mg/24 h, 69 ± 17 nmol/l, p0.01 respectively) compared with levels at diagnosis (10.6 ± 0.2 mg/dl, 223 ± 95 mg/24 h, 53 ± 15 nmol/l, respectively, p = 0.001). Overall, 38 of the 182 patients (20 %) died during follow-up; these patients were significantly older at diagnosis (76 ± 5 vs. 72 ± 4 years) but there were no differences in laboratory variables.While most patients had a formal indication for surgery, few underwent parathyroidectomy. Serum and urinary calcium significantly decreased during follow-up in patients who did not undergo surgery. Our data are reassuring and support at least the consideration of conservative treatment for these patients.

Background The use of thyroglobulin (Tg) and thyroglobulin antibodies (TgAb) for detecting disease recurrence is well validated following total thyroidectomy and radioiodine ablation. However, limited data are available for patients treated with thyroid lobectomy. Methods Patients who had lobectomy for papillary thyroid cancer followed for >1 year, with sufficient data on Tg and TgAb, including subgroup analysis for Hashimoto’s thyroiditis and contralateral nodules. Results One-hundred sixty-seven patients met the inclusion criteria. Average tumor size was 9.5 ± 6 mm. Following lobectomy, Tg was 12.1 ± 14.8 ng/mL. Of 52 patients with Hashimoto’s thyroiditis, 38% had positive TgAb with titers of 438 ± 528 IU/mL, and in patients without TgAb the mean Tg level was 14.7 ± 19.0 ng/mL. In 34 patients with contralateral nodules ≥1 cm, Tg was 15.3 ± 17 ng/mL. During the first 2 years of follow-up, Tg declined ≥1 ng/mL in 42% of patients (by 5.1 ± 3.7 ng/mL), remained stable in 22%, and increased in 36% (by 4.9 ± 5.7 ng/mL). During a mean follow-up of 6.5 years (78 ± 43.5 months), 18 patients had completion thyroidectomy and 12 were diagnosed with contralateral cancer (n = 8) or lymph node metastases (n = 4). In patients with recurrence followed for >2 years, there was a rise in Tg in 3 cases, Tg was stable in 2 cases, and in 1 TgAb decreased from 1534 to 276 IU/mL despite metastatic lymph nodes. Basal Tg and Tg dynamics did not predict disease recurrence. Conclusions Serum thyroglobulin used independently is of limited value for predicting or detecting disease recurrence following thyroid lobectomy. Other potential roles of Tg, such as detecting distant metastases following lobectomy, should be further studied.

Prolactinomas in men are usually large and invasive, presenting with signs and symptoms of hypogonadism and mass effects, including visual damage. Prolactin levels are high, associated with low testosterone, anemia, metabolic syndrome and if long-standing also osteoporosis. Medical treatment with the dopamine agonist, cabergoline, became the preferred first-line treatment for male prolactinomas as well as for giant tumors, leading to prolactin normalization in ~ 80% of treated men, and tumor shrinkage, improved visual fields and recovery of hypogonadism in most patients. Multi-modal approach including surgery and occasionally radiotherapy together with a high-dose cabergoline is saved for resistant and invasive adenomas. Experimental treatments including temozolomide or pasireotide may improve clinical response in men harboring resistant prolactinomas. Compared to other pituitary adenomas, secreting and non-secreting, where pituitary surgery is the recommended first-line treatment, men with prolactinomas will usually respond to medical treatment with no need for any additional treatment.

BackgroundNecrotizing soft tissue infection (NSTI) is a life-threatening infection associated with high morbidity and mortality. Treatment consists of surgery and antibiotics. Many studies have addressed NSTI and its subtypes, but few have reviewed the clinical, radiological, and pathological differences between the polymicrobial and monomicrobial diseases. The objective of our study was to evaluate the clinical, radiological, and pathological features of patients with polymicrobial (NSTI I) and monomicrobial (NSTI II) infections and their association with outcome.MethodsThe cohort consisted of patients hospitalized with NSTI at a tertiary medical center in 2002–2019. The medical charts were reviewed for clinical, radiological, and pathological features. Findings were compared between patients in whom blood/tissue bacterial cultures yielded one or more than one pathological isolate. The primary clinical outcome measure of the study was all-cause mortality at 90 days. Secondary outcomes were duration of hospitalization, intensive care unit (ICU) admission, score on the LRINEC (Laboratory Risk Indicator for Necrotizing Fasciitis), and need for vasopressor treatment.ResultsA total of 81 patients met the inclusion criteria: 54 (66.6%) with monomicrobial NSTI and 27 (33.3%) with polymicrobial NSTI. There were no significant between-group differences in in-hospital and 90-day mortality. On multivariate analysis, the monomicrobial disease group had a significantly higher 90-day mortality rate in addition to higher rates of in-hospital mortality, ICU admission, and vasopressor use than the polymicrobial disease group.ConclusionOur study is the first to compare the clinical, radiological, and pathological differences between the two most common types of NSTI. The results demonstrate better prognosis for polymicrobial NSTI, with minimal ICU stay, lower mortality, and lower use of vasopressors.Level of evidencePrognostic and epidemiological, level III.

Introduction: The 2015 American Thyroid Association (ATA) guidelines recommend response to therapy (RTT) assessment 1–2 years after initial treatment in differentiated thyroid cancer (DTC) patients...

Objectives Radioactive iodine (RAI) treatment is often indicated after total thyroidectomy in differentiated thyroid cancer (DTC). However, its role in biochemical or locoregional persistent DTC is unclear. We aimed to investigate the effect of a second RAI treatment in patients with incomplete response to initial treatment and no evidence of distant metastases. Methods Patients who underwent at least two RAI treatments over a 20-year period at a tertiary hospital were identified. Thyroglobulin levels and neck imaging were compared before and 1 to 2 years after RAI retreatment and evaluated at the last visit. Results The cohort included 164 patients (103 female; mean age, 46.6 ± 17 years). Of 114 patients retreated without prior reoperation, 53 had structural disease. At 1 to 2 years after RAI retreatment, 10 of the 41 patients with sufficient data had structural progression, 5 resolution/shrinkage, and 26 stable disease. Stimulated thyroglobulin (stTg) measured 93.7.1 ± 108 ng/mL before and 102.2 ± 124 ng/mL after retreatment (P = NS). The other 61 patients had biochemical-only persistence. Their stTg levels decreased from 41.9 ± 56 to 24.6 ± 54 ng/mL (P = 0.003). The 50 patients who underwent neck reoperation before RAI retreatment showed no substantial change in stTg; 21 (42%) still had imaging findings 1 to 2 years later. At final follow-up, despite additional treatment in 63/164 patients (38.4%), only 56/164 (34.1%) had no evidence of disease. Conclusions This comprehensive study showed limited benefit of second RAI treatment in DTC patients with biochemical or locoregional structural persistent disease. Prospective studies are needed to distinguish patients for whom repeated RAI may be indicated to avoid unnecessary exposure.

Objective: Male gender is considered an adverse prognostic factor for remission of Graves disease treatment with antithyroid drugs (ATDs), although published data are conflicting. This often results in early consideration of radioiodine treatment and surgery for men. Our objective was to compare disease presentation and outcome in men versus women treated with ATDs. Methods: Retrospective study of 235 patients (64 men, 171 women) with Graves disease who were evaluated for features at presentation and outcome at the end of follow-up between 2010 and 2015. Results: Disease presentation was similar in men and women for age at diagnosis (41.4 ± 14 years vs. 40 ± 15 years), duration of follow-up (6.6 ± 7 years vs. 7.7 ± 6 years), rates of comorbid autoimmune diseases, and rate of Graves ophthalmopathy. Smoking was more prevalent in males (31% vs. 15%; P = .009). Free thyroxine and triiodothyronine levels were comparable. ATDs were first-line treatment in all males and in 168 of 171 females, for a median duration of 24 and 20 months, respectively (P = .55). Remission rates were 47% in men and 58% in women (P = .14). Males had fewer adverse events (9% vs. 18%) and treatment discontinuation (5% vs. 16%). Disease recurrence was comparable (14% vs. 20%; P = .32), as was requirement for second-line treatment, either radioiodine therapy or thyroidectomy. Conclusion: Graves disease presentation is similar in men and women. Men treated with ATDs have high remission rates and similar recurrence rates compared to women, with fewer adverse events and less discontinuation of treatment. ATDs are an attractive first-line treatment for both genders.

Background Minimal extrathyroid extension (mETE) in patients with differentiated thyroid cancer (DTC) was defined as an intermediate risk feature in the 2015 American Thyroid Association guidelines. However, controversy persists as several studies suggested mETE has little effect on disease outcome. Objective To assess the impact of mETE on DTC patients' outcome. Methods Meta-analysis of controlled trials comparing patients with DTC with and without mETE. Data Extraction and Synthesis Thirteen retrospective studies including 23,816 patients were included, with a median follow-up of 86 months. mETE in patients without lymph node involvement (N0 disease) was associated with increased risk of recurrence [seven studies: odds ratio (OR), 1.73; 95% confidence interval (CI), 1.03 to 2.92]. The absolute risk of recurrence was 2.2% in patients without extension and 3.5% in patients with mETE (P = 0.04). In studies including patients with and without lymph node involvement (N1/N0 disease), mETE resulted in a significantly higher risk of recurrence (eight studies: OR, 1.82; 95% CI, 1.14 to 2.91). The absolute risk of recurrence was 6.2% in patients without extension and 7% in patients with mETE (P = 0.01). In patients with micropapillary carcinoma ( Conclusion mETE increases risk of recurrence in patients with DTC; however, the absolute increase in risk is small, and in patients with N0 disease the risk is within the low-risk of recurrence category at 3.5%. mETE has no impact on disease-related mortality and should not change tumor stage.

This study was conducted to examine the relationship between the degree of asymptomatic hyperuricemia and the development of gout, in men and women. The database of a screening center was searched for all subjects with asymptomatic hyperuricemia (>7.0 mg/dl men, >5.6 mg/dl women) during 2000–2012. We included men and women without previous diagnosis of gout, and a follow-up of at least 5 years. The risk of gout was analyzed in relation to the degree of hyperuricemia at the first visit. Of the 5,234 subjects who matched the inclusion criteria, 4,241 were normouricemic at their first visit and 993 were hyperuricemic. The mean follow up period was 7.5 years. Gout was diagnosed at the last visit in 34 subjects; four in the normouricemia group and 30 in the hyperuricemia group (0.1 % vs. 3.0 %, p

Objective To examine the prognostic implications of diabetes mellitus (DM) and the importance of glycemic control during hospitalization for infectious diseases. Methods Historical prospectively collected data of patients hospitalized between 2011 and 2013. Infection-related hospitalizations were classified according to site of infection. Median follow-up was 4.5 years. Outcome measures included in-hospital and end-of-follow-up mortality. Results The cohort included 8051 patients (50% female, mean age ± SD, 68 ± 20 years) with a primary diagnosis of an infectious disease. Of these, 2363 patients (29%) had type 2 DM. The most common infectious sites included respiratory tract (n = 3285), genitourinary tract (n = 1804), skin and soft tissue (n = 934) and gastrointestinal tract (n = 571). There was no difference in admission rates of patients with and without DM according to the site of infection, except for skin and soft tissue infection which were more common among patients with DM (16% vs 10%). In-hospital mortality risk was greater in patients with DM (aOR = 1.3, 95% CI = 1.1-1.7). In the entire cohort, adjusted mortality risk (aHR, 95% CI) at the end-of-follow-up was greater among patients with DM (1.2, 1.1-1.4), with increased mortality risk following hospitalization for respiratory (1.1, 1.0-1.4) and skin and soft tissue infections (1.7, 1.3-2.3). In-hospital and end-of-follow-up mortality risk were highest among patients with and without DM with median glucose >180 mg/dL during hospitalization. Conclusions In patients hospitalized for infectious diseases, DM is associated with increased long-term mortality risk, specifically following hospitalization for respiratory and skin and soft tissue infections. Poor glycemic control during hospitalization is associated with increased long-term mortality.

Kikuchi-Fujimoto disease is a benign and self-limited disease, first reported in Japan in 1972. The characteristic features of this disorder include lymphadenopathy and fever.To summarize our experience with Kikuchi disease with regard to clinical manifestations and outcome.The patients included in the study were those diagnosed with Kikuchi disease during the years 2005-2008 in two departments of internal medicine at Sheba Medical Center.We identified five patients with Kikuchi disease; four were women and the mean age was 22.6 years. All the patients had cervical lymphadenopathy; three had other sites of lymphadenopathy. Four of the patients had fever higher than 39 degrees C. Two of them had splenomegaly and three reported weight loss. Three of the five patients experienced a relapse of the disease and were treated with steroids or non-steroidal anti-inflammatory agents. The diagnosis was confirmed in all the patients by an excisional biopsy of lymph node.Kikuchi disease must be considered in every young patient with fever and lymphadenopathy. The disease usually has a benign course.
