RESUMO

Postmenopausal hyperandrogenism is an androgen excess originating from either the adrenals and/or the ovaries. Clinically, symptoms can be moderate (increase in terminal hair growth, acnea) or severe with signs of virilization (alopecia, clitoridomegaly). In either setting, physicians need to exclude relatively rare but potentially life-threatening underlying tumorous causes, such as adrenal androgen-secreting tumors. The objectives of this review are to evaluate which hormonal measurements (T, delta 4 androstenedione, 17 OH progesterone, SDHEA, FSH, LH) and/or imaging (pelvic ultrasound, MRI or adrenal CT-scan) could be useful identifying the origin of the androgen excess. Our review illustrates that the rate of progression of hirsutism and/or alopecia, and serum testosterone levels are in favor of tumors. Pelvic MRI and adrenal CT-scan are useful tools for identifying the different causes of androgen excess.

RESUMO

STUDY QUESTION: Is there an added diagnosis value of buccal cell FISH analysis compared with blood lymphocyte chromosomal investigations in patients with Turner syndrome (TS)? SUMMARY ANSWER: Buccal cell FISH analysis, a non-invasive technique, modified the chromosomal results obtained with the blood karyotype in 17 patients (12%) of our cohort. WHAT IS KNOWN ALREADY: Few studies have evaluated buccal cell FISH analysis and compared them with blood karyotype in patients with TS. STUDY DESIGN, SIZE, DURATION: A prospective, monocentric cohort study was conducted in a rare diseases centre (CMERC) between July 2017 and August 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS: In total, 142 adult patients with TS, and at least 5% 45,X cells in a previous blood karyotype, were recruited. All the patients' files were included in the CEMARA database. This national database has been declared to the French data protection agency (CNIL approval number 1187326). In compliance with French law, consent regarding non-opposition to collect and use the data was obtained from each patient. A FISH analysis on a buccal smear was performed. MAIN RESULTS AND THE ROLE OF CHANCE: The percentage of 45,X cells was identical between the two tissues in only 32.4% of cases. The discrepancy was higher than 41% for 12% of the cohort. The percentage of 45,X cells was higher in blood in 53 (37.3%) patients, and higher in buccal cells in 43 (30.3%) of cases. In 17 (12%) cases, the blood karyotype had to be reconsidered in regard to the buccal cell analysis. LIMITATIONS, REASONS FOR CAUTION: It would have been interesting to evaluate karyotypes in cells from other tissues such as cells from skin biopsy or from the urinary tract and even from blood vessels or gonads in case of surgery and to compare them with each patient's phenotype. However, most of the time, these tissues are not available. WIDER IMPLICATIONS OF THE FINDINGS: Although blood lymphocyte karyotype remains the gold standard for the diagnosis of TS, buccal cell FISH analysis is an efficient tool to evaluate the global chromosomal constitution in these patients, thus allowing them to have better care and follow-up. For instance, identifying a Y chromosome can prevent the occurrence of a gonadoblastoma, as gonadectomy should be discussed. On the other hand, finding normal XX cells in a patient with a previous diagnosis of homogenous 45,X TS, may be psychologically helpful and relevant for gynaecological care. STUDY FUNDING/COMPETING INTEREST(S): No specific funding was sought for the study. The authors declare no competing interests. TRIAL REGISTRATION NUMBER: N/A.

RESUMO

STUDY QUESTION: What are the consequences of radioactive iodine (RAI) therapy for testicular function? SUMMARY ANSWER: A single activity of 3.7 GBq RAI for differentiated thyroid carcinoma (DTC) treatment in young men transiently altered Sertoli cell function and induced sperm chromosomal abnormalities. WHAT IS KNOWN ALREADY: Few studies, mainly retrospective, have reported the potential impacts of RAI on endocrine and exocrine testicular function. STUDY DESIGN, SIZE, DURATION: A longitudinal prospective multi-center study on testicular function performed in DTC patients before a single 131I ablative activity of 3.7 GBq (V0) and at 3 months (V3) and 13 months (V13) after treatment. PARTICIPANTS/MATERIALS, SETTING, METHODS: Forty male patients, aged 18-55 years, with DTC participated. Hormonal analysis included FSH, LH, testosterone and inhibin B serum levels at V0, V3 and V13. Furthermore, sperm parameters, DNA fragmentation and sperm chromosomal abnormalities were evaluated at each time points. The differences in all parameters, between V0-V3, V0-V13 and V3-V13, were analyzed, using a Wilcoxon test. MAIN RESULTS AND THE ROLE OF CHANCE: Prior to RAI administration, all patients had normal gonadal function. At V3, a statistically significant increase in FSH levels and a decrease in inhibin B levels were observed and sperm concentration, as well as the percentage of morphologically normal spermatozoa, were significantly decreased (P < 0.0001). These modifications were transient as both sperm concentration and normal morphology rate returned to baseline values at V13. However, at this later time point, FSH and inhibin B levels were still impacted by RAI administration but remained in the normal range. Although no DNA fragmentation was observed at V3 nor V13, our study revealed a statistically significant increase in the number of sperm chromosomal abnormalities both at V3 (P < 0.001) and V13 (P = 0.01). LIMITATIONS, REASONS FOR CAUTION: Among the 40 patients included in the study, only 24 had all the parameters available at all visits. WIDER IMPLICATIONS OF THE FINDINGS: Prospective studies with longer term follow up would be helpful to determine whether the chromosome abnormalities persist. These studies would be required before sperm banking should be suggested for all patients. However, sperm preservation for DTC patients who require cumulative radioiodine activities higher than 3.7 GBq should be proposed. STUDY FUNDING/COMPETING INTEREST(S): This study was supported by the Programme Hospitalier de Recherche Clinique, AP-HP (No. P040419). The authors report no conflict of interest in this work. TRIAL REGISTRATION NUMBER: NCT01150318.

RESUMO

The endocrine and exocrine functions of the gonads are controlled by the gonadotrope axis, whose master regulator is the hypothalamic decapeptide GnRH. The Kisspeptin/Neurokinin B (Kp/NkB) neuronendocrine system is the main physiologic regulator of GnRH neurons. The Kp/NkB system is currently considered the key mediator for the hypothalamic negative feedback exerted by sex steroids and prolactin, as well as by various metabolic signals. Intrinsic alterations or regulatory abnormalities of Kp/NkB system lead to various gonadotrope axis puberty and fertility dysfunctions. Molecular inactivations of Kp/NkB system actors are associated with some forms of congenital hypogonadotropic hypogonadism without anosmia. The Kp/NkB System is also involved in a few forms of precocious puberty. Finally, the Kp/NKB system is also implicated in gonadotrope axis alterations leading to functional hypothalamic amenorrhea or hyperprolactinemia. NkB is particularly and directly involved in vasomotor menopausal hot flushes mechanism. Various Kp/NkB agonist/antagonist compounds have been developed during the last ten years, and are currently being evaluated in humans. These molecules have potential applications not only in rare genetic diseases with Kp/NkB alterations, but also in various gonadotrope axis-related diseases or in vitro fertilization. The administration of NkB antagonists in menopausal women represents a real therapeutic advance because of their impressive effect in controlling vasomotor menopausal hot flushes.

RESUMO

Without appropriate treatment, Group A streptococcal infections can lead to post-streptococcal syndrome, including post-streptococcal uveitis. This should be kept in mind in young patients with acute bilateral non-granulomatous anterior uveitis, in order to avoid ocular and systemic complications. We report two cases of bilateral post-streptococcal anterior uveitis, in young men, of respectively 20 and 16 years old, that presented to Jules Gonin Eye Hospital.

RESUMO

CONTEXT: Premature ovarian insufficiency (POI) may be secondary to chemotherapy, radiotherapy, or environmental factors. Genetic causes are identified in 20-25% of cases, but most POI cases remain idiopathic. OBJECTIVE: This study aimed to identify new genes involved in POI and to characterize the implication of CPEB1 gene in POI. DESIGN AND SETTING: This was a case report and cohort study replicate conducted in academic medical centers. PATIENTS AND METHODS: A deletion including CPEB1 gene was first identified in a patient with primary amenorrhea. Secondly, 191 sporadic POI cases and 68 familial POI cases were included. For each patient, karyotype was normal and FMR1 premutation was excluded. Search for CPEB1 deletions was performed by quantitative multiplex PCR of short fluorescent fragments or DNA microarray analysis. Gene sequencing of CPEB1 was performed for 95 patients. RESULTS: We identified three patients carrying a microdeletion in band 15q25.2. The proximal breakpoint, for the three patients, falls within a low-copy repeat region disrupting the CPEB1 gene, which represents a strong candidate gene for POI as it is known to be implicated in oocyte meiosis. No mutation was identified by sequencing CPEB1 gene. Therefore, heterozygous deletion of CPEB1 gene leading to haploinsufficiency could be responsible for POI in humans. CONCLUSION: Microdeletions of CPEB1 were identified in 1.3% of patients with POI, whereas no mutation was identified. This microdeletion is rare but recurrent as it is mediated by nonallelic homologous recombination due to the existence of low-copy repeats in the region. This result demonstrates the importance of DNA microarray analysis in etiological evaluation and counseling of patients with POI.

RESUMO

Prolactin is a major hormone, involved in gonadotroph axis regulation. Hyperprolactinemia induces gonadotropin deficiency and therefore hypogonadotropic hypogonadism. It should be suspected in front of menstrual cycle abnormalities, infertility and/or galactorrhea. If drugs and/or PRL adenoma represent the vast majority of causes of hyperprolactinemia, other etiologies and misleading diagnosis of hyperprolactinemia should be searched for. After eliminating a pregnancy, in women of childbearing age, the first step is to interpret the result of hyperprolactinemia, according to the assay technique used. Indeed, the major active form of prolactin is the 23kDA non-glycosylated prolactin. However, some assays interfere with macroprolactinemia, an inactive form of prolactin, including glycosylated prolactin bound to an IgG immunoglobulin. Its presence in the serum is misleading as it may induce increased levels of prolactin, usually below 100 ng/mL. The diagnosis of macroprolactinemia has major issues as pituitary MRI does not need to be performed. Furthermore, neither treatment nor follow-up of patients with macroprolactinemia are necessary. It should be suspected in the presence of normal menstrual cycles. Drugs inducing hyperprolactinemia usually raise prolactin levels below 100 ng/mL. If prolactin level is higher than 250 ng/mL, the main diagnosis is pituitary macro-adenoma. If prolactin ranges between 100 and 250 ng/mL, it is usually related to a micro-adenoma or a necrotic macro-adenoma. A mixed PRL/GH should always be suspected. If prolactin level is below 150 ng/mL, in the presence of a large hypothalamic-pituitary tumor, the major diagnosis is hyperprolactinemia due to pituitary disconnection. Ectopic secretions of prolactin remain very rare. A new etiology of hyperprolactinemia is loss of function mutation of prolactin receptor.

RESUMO

BACKGROUND: MEN1, which is secondary to the mutation of the MEN1 gene, is a rare autosomal-dominant disease that predisposes mutation carriers to endocrine tumors. Most studies demonstrated the absence of direct genotype-phenotype correlations. The existence of a higher risk of death in the Groupe d'étude des Tumeurs Endocrines-cohort associated with a mutation in the JunD interacting domain suggests heterogeneity across families in disease expressivity. This study aims to assess the existence of modifying genetic factors by estimating the intrafamilial correlations and heritability of the six main tumor types in MEN1. METHODS: The study included 797 patients from 265 kindred and studied seven phenotypic criteria: parathyroid and pancreatic neuroendocrine tumors (NETs) and pituitary, adrenal, bronchial, and thymic (thNET) tumors and the presence of metastasis. Intrafamilial correlations and heritability estimates were calculated from family tree data using specific validated statistical analysis software. RESULTS: Intrafamilial correlations were significant and decreased along parental degrees distance for pituitary, adrenal and thNETs. The heritability of these three tumor types was consistently strong and significant with 64% (s.e.m.=0.13; P<0.001) for pituitary tumor, 65% (s.e.m.=0.21; P<0.001) for adrenal tumors, and 97% (s.e.m.=0.41; P=0.006) for thNETs. CONCLUSION: The present study shows the existence of modifying genetic factors for thymus, adrenal, and pituitary MEN1 tumor types. The identification of at-risk subgroups of individuals within cohorts is the first step toward personalization of care. Next generation sequencing on this subset of tumors will help identify the molecular basis of MEN1 variable genetic expressivity.

RESUMO

CONTEXT: Multiple endocrine neoplasia Type-1 (MEN1) in young patients is only described by case reports. OBJECTIVE: To improve the knowledge of MEN1 natural history before 21 years old. METHODS: Obtain a description of the first symptoms occurring before 21 years old (clinical symptoms, biological or imaging abnormalities), surgical outcomes related to MEN1 Neuro Endocrine Tumors (NETs) occurring in a group of 160 patients extracted from the "Groupe d'étude des Tumeurs Endocrines" MEN1 cohort. RESULTS: The first symptoms were related to hyperparathyroidism in 122 cases (75%), pituitary adenoma in 55 cases (34%), nonsecreting pancreatic tumor (NSPT) in 14 cases (9%), insulinoma in 20 cases (12%), gastrinoma in three cases (2%), malignant adrenal tumors in 2 cases (1%), and malignant thymic-NET in one case (1%). Hyperparathyrodism was the first lesion in 90 cases (56%). The first symptoms occurred before 10 years old in 22 cases (14%) and before 5 years old in five cases (3%). Surgery was performed before age 21 in 66 patients (41%) with a total of 74 operations: pituitary adenoma (n = 9, 16%), hyperparathyroidism (n = 38, 31%), gastrinoma (n = 1, 33%), NSPT (n = 5, 36%), and all cases of insulinoma, adrenal tumors, and thymic-NET. One patient died before age 21 due to a thymic-NET. Overall, lesions were malignant in four cases. CONCLUSIONS: Various MEN1 lesions occurred frequently before 21 years old, but mainly after 10 years of age. Rare, aggressive tumors may develop at any age. Hyperparathyroidism was the most frequently encountered lesion but was not always the first biological or clinical abnormality to appear during the course of MEN1.

RESUMO

Pregnancy is an immunological paradox that implies that a semi-allogeneic fetus is not rejected by the maternal immune system, from implantation of the embryo to delivery. Progesterone (P4), estradiol (E2) and human chorionic gonadotropin (hCG), contribute to the transformation of immune cells in a transient tolerance state, necessary to the maintenance of pregnancy. The effects of pregnancy hormones depend probably of their maternal plasma level. hCG is dangerous at high concentrations because it can stimulate autoantibodies production, whereas in physiological concentrations, hCG, P4 and E2 upregulate immune response expanding regulatory T and B cells, allowing the fetus to grow within the maternal uterus in a protective environment. A second example of fetal-maternal relation found recently is the role of maternal nutrition on development of the fetal hypothalamic neurons. Experiments in mice fed on a high fat diet reveal a critical timing when altered maternal metabolism affect formation of hypothalamic neurocircuits of the offspring and predispose him to long-term metabolic disorders.

RESUMO

Amenorrhea in adolescents can be primary, with or without breast development, or secondary. Whether amenorrhea is primary or secondary, height, body mass index, food intake, the level of physical activity per week, the presence of hirsutism or galactorrhea, pelvic pain and past history of intercourse need to be investigated. Initially, blood tests should include hCG, FSH, estradiol, testosterone and prolactin serum levels. This screening will discriminate between hypogonadotropic hypogonadism and amenorrhea from primary ovarian insufficiency (POI). In case of primary amenorrhea, hypogonadism may be due to congenital hypogonadotropic hypogonadism (HH) or more rarely acquired HH. If FSH is elevated, amenorrhea is due to primary ovarian failure, mainly related to Turner syndrome. If pubertal development is normal, a pelvic ultrasound should be performed. It may visualize a hindering of menses output or less frequently an absence of uterus, as in Rokitansky syndrome or androgen insentivity syndrome. The most frequent etiologies of secondary amenorrhea are polycystic ovarian syndrome (PCOS), functional hypothalamic amenorrhea and less frequently POI and hyperprolactinemia. The differential diagnoses of PCOS are late-onset 21-hydroxylase deficiency and very rare ovarian or adrenal tumors. When contraception is not necessary, hormonal replacement therapy, including estrogen and progestins should be administered in order to avoid hypoestrogenism. In case of PCOS, sequential progestins can be prescribed. A contraceptive pill can be considered when contraception is needed and/or when hyperandrogenism needs to be treated.

RESUMO

Orthopaedic surgery has low healthcare-associated infection incidences compared to other surgical disciplines. However, whenever they occur, these infections are associated with substantial morbidity, prolonged hospital stay, high costs, and difficulties of eradication with life-long recurrence risks. Among the many measures to prevent orthopaedic surgical site infections, only few are based on strong evidence, and there is insufficient evidence to ascertain which element is superior to any other. This highlights the need for multimodal approaches involving active post-discharge surveillance, as well as measures at every step of the care process; from the individual patient to department-wide interventions targeting all infections, and including antibiotic stewardship.

RESUMO

BACKGROUND Nomegestrol acetate/17ß-estradiol (NOMAC/E(2)) is a new monophasic oral contraceptive combining NOMAC (2.5 mg), a highly selective progesterone-derived progestogen, with E(2) (1.5 mg), which is structurally identical to endogenous estrogen. The objective of this study was to compare the effects on ovarian activity of two different NOMAC/E(2) regimens. METHODS This was a double-blind, randomized study. Healthy, premenopausal women (aged 18-38 years, previous menstrual cycle length 28 ± 7 days) were randomized by computer-generated code to once-daily NOMAC/E(2) for three consecutive 28-day cycles: either 24 days with a 4-day placebo interval (n = 40) or 21 days with a 7-day placebo interval (n = 37) per cycle. Follicular growth (primary outcome measure), plasma hormone profiles and bleeding patterns were assessed. RESULTS There was no evidence of ovulation during treatment with either NOMAC/E(2) regimen. The largest follicle diameter was significantly smaller in the 24-day group than in the 21-day group [mean (SD) mm in cycle 2: 9.0 (3.0) versus 11.3 (5.3) (P = 0.02); in cycle 3: 9.2 (3.0) versus 11.5 (6.0) (P = 0.04)]. Mean FSH plasma levels were significantly lower in the 24-day versus the 21-day group on Day 24 of cycles 1 and 2. Withdrawal bleeding duration was significantly shorter in the 24-day than in the 21-day group [mean (SD) days after cycle 1: 3.5 (1.3) versus 5.0 (2.6) (P = 0.002); after cycle 2: 3.9 (1.6) versus 4.8 (1.7) (P = 0.03)]. CONCLUSIONS The 24-day NOMAC/E(2) regimen was associated with greater inhibition of follicular growth and shorter duration of withdrawal bleeding than the 21-day regimen, suggesting the shorter pill-free interval results in a greater margin of contraceptive efficacy and tolerability, and fewer withdrawal symptoms.

RESUMO

We report the case of a 21-year-old pregnant women (36 WA) presenting intensive headaches and visual disturbances. Those sellar compression symptoms have made us suppose the diagnosis of autoimmune hypophysitis. MRI has confirmed the typical aspect of symmetric enlargement of the pituitary gland with a strong and homogenous enhancement after gadolinium. This pathology associated to a high morbidity and mortality due to partial or complete deficit of the anterior pituitary hormones, shall be reminded more often.

RESUMO

BACKGROUND AND AIMS: Right colonic diverticulitis is not a frequent disease and its management is still controversial. In this study we describe our experience. MATERIAL AND METHODS: We retrospectively reviewed all patients operated on because of a right colonic diverticulitis in our surgical unit. All patients were treated laparoscopically. Demographics, diagnostic and surgical results were recorded. RESULTS: Between January 1994 and January 2007, 11 patients (7 males and 4 females) mean age 53 +/- 9 years (range 39-68), ASA 1: 6 patients, ASA 2: 4 patients, ASA 3: one patient, and BMI 27.8 (range 25-31), had right colonic diverticulitis. Four patients underwent emergency operations: one for peritonitis and three with an erroneous diagnosis of acute appendicitis; seven were operated on electively. There were no deaths or complications. The mean postoperative hospital stay was 5.6 days (range, 3-9). After a mean follow-up of 6.3 years (range 1-13) all patients of this series are symptom-free. INTERPRETATION AND CONCLUSION: Right colon diverticulitis diagnosis remains difficult. A pre-operative imaging screening is necessary to successfully face this challenging disease. Laparoscopy is a safe and effective method to treat these patients. Colectomy should be considered a good therapeutic option for right colonic diverticulitis, although a conservative approach could be proposed in selected cases.

RESUMO

Müllerian inhibiting substance (MIS) has been discovered by Alfred Jost at the beginning of the fifties. MIS is a glycoprotein belonging to the TGF-beta family. Its various functions differ between males and females and according to the age of the individual. In male, the protein is synthesized by Sertoli's cells and induces the disappearance of Müllerian's ducts, the development of the male genital tract. Its role in adult males remains quite unknown. In female, the protein is secreted by granulosa cells and plays a role during folliculogenesis as it regulates the initial and cyclic recruitment of ovarian follicles. MIS is also a good marker of follicular reserve and ovarian function. Therefore, it plays a role in different areas such as assisted medical reproduction and oncology. This protein represents a potential major diagnosis as well as prognostic tool in reproduction.

RESUMO

INTRODUCTION: We report two cases of hypercalcemia-hyperleucocytosis paraneoplastic syndrome complicating cutaneous squamous cell carcinoma. CASE REPORTS: The first patient, a 50-year-old man, suffering for hidradenitis suppurativa for the past 20 years, was admitted for squamous cell carcinoma. Laboratory findings showed marked hypercalcemia and hyperleucocytosis. PTHrP serum level was increased. Bone scintigraphy was normal. There was evidence of pulmonary metastasis. Despite treatment the patient died of agranulocytosis. The second patient was a 60-year-old man who presented with several months enlarging left axillary tumour. He has been treated by surgery for a squamous cell carcinoma of the left hand, 6 months ago. Serum calcium and white cell bloods count were elevated. The diagnosis of metastatic lymph node of cutaneous squamous cell carcinoma was confirmed. There was evidence of pulmonary metastasis. Despite chemotherapy the patient died rapidly. CONCLUSION: Hypercalcemia-hyperleucocytosis paraneoplastic syndrome is rarely described during the course of cutaneous squamous cell carcinoma. This syndrome seems to be related to hormones or cytokines secretion by the neoplasic cells including PTHrP and G-CSF. Some authors ascribe it a poor prognostic significance.

RESUMO

1. Metformin is not efficient enough in order to regulate menstrual cycles. 2.Metformin is not efficient enough in order to treat hyperandrogenism. 3. Metformin should not be used as a first-line treatment in order to treat infertility. Clomiphene citrate (CC) is the reference treatment. 4. Metformin in addition to CC is not recommended as a second line treatment, after the failure of CC alone. 5. Metformin should not be used during pregnancy in non diabetic women with PCOS, in order to prevent the risk of gestational diabetes. 6. Metformin should be prescribed to PCOS women when they are diabetic, in order to prevent their cardiovascular risk, after lifestyle modification. 7. Metformin should not be used in PCOS non diabetic women in order to lose weight. Metformin should not be used in order to treat dyslipidemia in women with PCOS. 8. In PCOS women, without diabetes, but with fasting hyperglycemia or carbohydrate intolerance, metformin should be prescribed if: BMI>35.

RESUMO

Weight, fat mass and obesity have been shown to play a major role in female reproduction. Obese women have a greater risk than nonobese women of infertility and they fail to become pregnant in both natural and assisted conception cycles. This cannot be explained only by their lack of ovulation. There are several potential mechanisms. On one hand, the endometrium seems to be partially responsible for this low fecundity in obese women. On the other hand, the oocyte seems to be implied. In a model of obese mouse, maternal obesity prior to conception is associated with altered mitochondria in mouse oocytes and an increased generation of reactive oxygen species (ROS). Furthermore, compared with controls, obese mice have significantly more decreased embryonic IGF-IR staining, smaller fetuses and smaller pups. In this model, all weaned pups have been fed with a regular diet. At 13 weeks, pups delivered from obese mice were significantly larger, and these pups demonstrated early development of a metabolic-type syndrome. These findings suggest that maternal obesity has adverse effects as early as the oocyte and preimplantation embryo stages and that these effects may contribute to lasting morbidity in offspring, underscoring the importance of optimal maternal weight and nutrition before conception.

RESUMO

AIM: Urgent appendectomy in patients with acute appendicitis (AA) complicated by abscess or phlegmon is associated with a high rate of complications. Recent developments in CT scanning have allowed patients with complicated appendicitis to be better identified. We choose to treat these patients with initial antibiotic therapy followed by elective appendectomy. We reported the results of this strategy and compared it with urgent appendectomy. METHODS: A retrospective analysis of patients diagnosed with complicated acute appendicitis (CAA) between 1998 and 2007 treated either by urgent appendectomy or with antibiotic therapy and elective appendectomy was performed. We assessed the efficacy of antibiotic therapy for CAA. We compared the postoperative course between urgent and elective appendectomy. RESULTS: We treated 56 patients with CAA: 40 by urgent appendectomy and 16 by antibiotics. All 16 patients improved with no need for urgent surgery, with 15 undergoing elective appendectomy. Postoperative complications were significantly lower in the elective group. Conversion rate and mean operative time were also lower but not significantly different. However, the duration of total hospital stay, antibiotic therapy and sick leave were higher. CONCLUSIONS: Initial antibiotic therapy followed by elective appendectomy may be proposed in patients diagnosed with CAA.
