RESUMO
Background: Robotic-assisted hysterectomy (RAH) is a widely accepted minimally invasive approach for uterus removal. However, as RAH is typically performed in the umbilical region, it usually results in scars in cosmetically suboptimal locations. This is the first case of RAH with cervicosacropexy performed below the bikini line, using the new Dexter robotic system™. Objectives: The aim of this article is to show the surgical steps of the first RAH with cervicosacropexy performed below the bikini line with the new Dexter robotic system™ (Distalmotion), and furthermore assess the feasibility of this approach using this robotic platform. Materials and Methods: A 43-year-old woman with uterine adenomyosis and recurrent uterine prolapse underwent a robotic-assisted subtotal hysterectomy with cervicosacropexy, performed below the bikini line, using the Dexter robotic system™, at the Clinic of Gynecology and Obstetrics at Universitätsklinikum Schleswig-Holstein (UKHS) in Kiel, Germany. Main outcome measures: Perioperative data, surgical approach specifics, objective, and subjective outcomes of this new approach. Results: The procedure was performed without intra-operative complications; estimated blood loss was 10 ml. Operative time was 150 minutes, console time 120 minutes, total docking time 6 minutes. Dexter performed as expected; no device-related issues or robotic arm collisions occurred. The patient did not require pain medication and was released on the second postoperative day. Conclusion: RAH performed below the bikini line using the Dexter robotic system™ is a feasible, safe, and adequate procedure. These initial results should be confirmed and further extensively refurbished with larger patient cohorts, and functional and psychological outcomes need further investigation.
RESUMO
OBJECTIVE: Cervical cancer (CC) is a preventable women's cancer. Vaccination and routine Pap smear screening have reduced cervical cancer-related mortality by 70-80% in the world. The eradication of CC depends on identifying the disease early and removing barriers to its timely detection. This review study was designed to determine diagnostic delay and factors related to delayed CC diagnosis in the world. MATERIALS AND METHODS: A comprehensive search was carried out in databases including Medline, Web of Science, Core Collection (Indexes = SCI-EXPANDED, SSCI, A & HCI Timespan), and Scopus for articles published up to December 2021. Publications were included if they reported data on the delayed CC, and factors related to diagnosis of CC in women. There was no time restriction in this review. RESULTS: In total, 45 articles were entered into the study. In studies, advanced stages of CC (IIB to IV) varied from 10.2% to 87.9% due to delayed diagnosis. A delayed CC diagnosis was reported in 4.3%-89.1% of patients. The median and mean days of delayed diagnosis were 59-210 days and 2.92-10.5 months, respectively. Factors related to delayed CC diagnosis were categorized into three components including patient, medical history, and health system delay. Patient delay included socio-demographic, husband/ partner, and knowledge. Medical history included medical issues, obstetrics, and family history. Health system delays included health facilities and levels of accessibility. CONCLUSIONS: There is an urgent need to shorten the diagnostic journey of CC patients by addressing all the components of diagnostic delay and developing strategies to modify the factors associated with these delays.

INTRODUCTION: Da-Vinci-Xi is the most recent device used in gynecologic robotic surgery. The aim of the present study was to compare the long-term satisfaction of patients who had undergone conventional laparoscopic hysterectomy or robotic assisted laparoscopic hysterectomy using the Da-Vinci-Xi surgical system. METHODS: All hysterectomies performed at the University Hospital of Luebeck from 2018 to 2019 were reviewed. Postoperative outcomes were compared between women who had undergone total hysterectomy with da Vinci Xi (n = 42) or conventional laparoscopy (n = 97). Postoperative outcomes included pain, elimination of complaints after surgery, bladder function, sexual function, satisfaction with the cosmetic outcome, positive experiences after robotic surgery, and satisfaction with the surgeon's preoperative explanation. Obese patients were evaluated separately in a subgroup analysis. RESULTS: Both groups had similar baseline characteristics and complication rates. Preoperative complaints subsided after surgery in a little more than 90% of patients. No significant differences were noted between groups in this regard (p = 0.262), or with reference to postoperative pain after one week (p = 0.866) and one month (p = 0.580), stress incontinence (p = 0.343), sexual function (p = 0.766) and the cosmetic outcome of the abdominal incisions (p = 0.273). The majority of patients who had undergone robotic surgery (96.8%) would be willing to undergo the procedure again if necessary. The subgroup analysis of obese patients revealed no significant differences. CONCLUSION: The Da-Vinci-Xi device did not improve the long-term surgical satisfaction of normal-weight or obese patients who underwent hysterectomy compared with patients who underwent conventional laparoscopy performed by experienced laparoscopic surgeons.

OBJECTIVE: Cervical cancer is largely preventable. Although routine Pap smear screening has reduced cervical cancer-related mortality by 70-80% in all countries and by approximately 90% in developing countries, the gynecologist is still confronted with women in advanced stages of the disease. The eradication of cervical cancer depends on identifying the disease early and removing barriers to its timely detection. Given the significant burden of cervical cancer in Asian countries, we investigated factors related to its screening in Asia. MATERIALS AND METHODS: A comprehensive search was carried out in databases such as Medline, Web of Science and Scopus for articles published until September 2020. The following keywords were used: vaginal smear, Pap smear, cervical cancer screening, barriers, obstacles, challenge, early detection, the name of each Asian country, and a combination of these words. RESULTS: Seventy-five articles were included in the study. The investigation revealed various factors related to cervical cancer screening in Asian women, including sociodemographic factors, awareness, attitudes and beliefs, perceived risk, psychological factors, self-efficacy, previous experiences, time, household, culture, fatalism, social support, access, cost, safety, insurance and health system-related factors. CONCLUSIONS: Several barriers hinder the efficacy of a screening program. Its success requires the use of educational interventions, professional and inter-professional cooperation, allocation of sufficient resources, and policymakers focusing on the elimination of barriers.

OBJECTIVE: This study was designed to investigate the incidence the premalignant and malignant cervical lesions at the 12-month follow-up investigation between cryotherapy and non-cryotherapy groups. PATIENTS AND METHODS: A prospective cohort study was performed in women with CIN 1 and PCB, who were referred to the gynecology clinic at Imam Hospital affiliated to Mazandaran University of Medical Sciences (MAZUMS), Sari, Iran, from February 2015 to November 2019. Of 232 patients, 131 consented to cryotherapy and underwent the treatment, while 101 were unwilling to undergo the treatment. After 12 months, we performed a Pap smear, a colposcopy, and a histopathological investigation of the cervix in both groups. Primary and secondary outcomes were compared between groups. The primary outcome was the comparison of incidence premalignant and malignant cervical lesions in cryotherapy and non-cryotherapy groups. The secondary outcome was a comparison of the accuracy of the Pap smear test versus colposcopy for the detection of premalignant and malignant cervical lesions in women with or without a history of cryotherapy. PATIENTS: Totally, abnormal cytological, positive colposcopic, and positive histopathological findings were reported in 41.56%, 20.26%, and 13.79 %, respectively. By histology biopsy, premalignant and malignant cervical lesions were reported in 28.24% (37/131) and 36.63% (32/101) of women in the cryotherapy and the non-cryotherapy group, respectively. This statistic did not differ significantly between groups (p = 0.78). Pap smears were abnormal in 39.7% and 44.5% of women in the cryotherapy and the non-cryotherapy group, respectively. A positive colposcopy was obtained in 27 (20.6%) and 19 (18.8%) women in the cryotherapy and the non-cryotherapy group, respectively. The diagnostic accuracy of the Pap smear test and colposcopy in detecting cervical neoplasia did not differ in women who had undergone cryotherapy and those who had not (p>0.05). CONCLUSIONS: This prospective study showed that cryotherapy is no appropriate treatment for patients with CIN1 and PCB.

BACKGROUND: Müllerian duct anomalies are congenital malformations of the female genital tract and may be of various types. For decades they have been classified according to the American Society of Reproductive Medicine, which mentions unicornuate uterine malformations as the second subgroup. They result from the arrested development of one of the Müllerian ducts and appear in approximately 1/1000 women. These anomalies are usually diagnosed in the second decade of life, because they tend to remain asymptomatic until adolescence and their initial symptoms may vary. Patients present with symptoms such as dysmenorrhea, infertility, and chronic or acute abdominal pain. CASE PRESENTATION: We report on a 21-year-old Caucasian German patient who suffered from dysmenorrhea for 7 years. After a transvaginal ultrasound and magnetic resonance tomography of the pelvis was performed, the patient underwent a diagnostic hysteroscopy and operative laparoscopy, and was finally diagnosed with a Müllerian duct anomaly presenting with a non-communicating rudimentary uterine horn. The left tube arose directly in orthotopic location from the cornua of uterus, with no connection to the rudimentary uterine horn or structure. CONCLUSION: The anatomic features of this case have not been reported previously and were not consistent with any existing classification. More cases are needed in order to confirm our hypothesis. Gynecologists should always consider Müllerian anomalies as an important differential diagnosis in young patients with abdominal pain.

INTRODUCTION: Despite the less frequent use of surgery in patients with vulvar cancer, the high rates of postoperative complications are still a matter of concern. The aim of the present study was to identify risk factors that influence postoperative complications rates in vulvar cancer and identify specific clinical parameters that may influence their incidence. MATERIALS: Patients who underwent curative-intent surgery for squamous cell carcinoma of the vulva from 2003 to 2018 were selected. All patient characteristics were analyzed as risk factors for the development of postoperative lymphocele, lymphedema, and wound dehiscence. The patients were followed up for 2 years postoperatively. RESULTS: The investigation comprised 121 patients, of whom 18.1% developed wound dehiscence, 17.7% a lymphocele, and 20.4% lymphedema. We found no significant evidence of an association between patient's characteristics and postoperative complications. The depth of tumor invasion and the appearance of lymph-node metastasis were significantly associated with postoperative complications. Free resection margins of 5 mm or more were associated with a reduced risk of postoperative complications compared to resection margins less than 5 mm. No complications were encountered after sentinel node biopsy (SNB). Complication rates were associated with inguinofemoral lymphadenectomy, but not with the extent of lymphadenectomy. The development of a lymphocele or wound dehiscence may be correlated with the development of long-term lymphedema. CONCLUSION: FIGO stage at diagnosis influences the risk of postoperative complications. The use of SNB minimized postoperative complications. Correlations between the free microscopic resection margin distance and the risk of postoperative wound dehiscence must be investigated further.

PURPOSE: During the last decade, electromechanical power morcellation (EMM) was more frequently used but it may be associated with the dissemination of occult malignancies. The aim of the present study was to determine the frequency of unexpected uterine malignancies after EMM. METHODS: This retrospective study consisted of patients who were treated at three departments of Gynecology in Germany from 2008 to 2017. We identified women who underwent an operation with the use of EMM. Clinical records, risk factors, and the outcomes of the patients were reviewed. RESULTS: We performed an analysis of 1683 patients who had undergone laparoscopic supracervical hysterectomy (LASH), total hysterectomy, or myomectomy (LM) (48.6%, 8.4%, and 43.0%, respectively). Unexpected malignancies were detected in 4 of 1683 patients (0.24%). In all cases, the malignancy proved to be a sarcoma and was detected after LASH. All patients with occult sarcomas were older than 45 years and the most common (75%) risk factor was the appearance of a solitary tumor. The patients underwent secondary laparotomy for complete oncological staging, and no histological dissemination of the sarcoma was registered. Two patients had a recurrence. At the final follow-up investigation all four patients were in good general health. CONCLUSION: Occult malignancies are liable to spread after EMM, although the overall risk of being diagnosed with an occult malignancy and the risk of dissemination appear to be low. Once the preoperative diagnostic investigation has yielded no suspicious findings, laparoscopic morcellation may be considered a safe method, especially LM in patients of reproductive age.

PURPOSE: The aim of this study was to estimate the accuracy of intra-operative frozen section (FS) diagnosis during hysterectomy for early-stage endometrial cancer (EC). METHODS: At the Department of Obstetrics and Gynecology, University of Luebeck, between 2009 and 2014, the intra-operative FS pathology of 164 patients with pre-operative endometrial curettage, showing G1 or G2 endometrioid EC at an early clinical stage (FIGO I-II), was compared retrospectively with the final paraffin section reports. The accuracy of myometrial invasion (MI) in all patients and separately in stage FIGO I patients was calculated and the under- or overtreatment of the patients was analyzed. A subgroup analysis was performed focusing on the percentage of inadequate staging by FS with clinical consequences. RESULTS: Concordance of FS and final pathology results in terms of FIGO stage was 85.2%, with an under-diagnosis rate of 14% and an over-diagnosis rate of 0.8%. The subgroup analysis rate of patients who were inappropriately operated using FS was 6.6%, while 3.3% underwent a secondary operation. The overall accuracy of FS in predicting MI was 93.3% and in patients with stage FIGO I, 92.7%. Sensitivity, specificity, PPV and NPV were 98.25%, 89.06%, 88.89% and 98.28%, respectively, and in stage FIGO I, 98.25%, 84.62%, 90.32% and 97.06%, respectively. CONCLUSION: The authors consider that intra-operative FS is a reliable diagnostic method to identify the clinical stage of EC and especially MI, to determine the necessity of lymphadenectomy. Further development of diagnostic techniques is essential to maximize diagnostic accuracy.

Introduction: Ductal carcinoma in situ (DCIS) is a premalignant lesion of the glandular component of the breast and a precursor lesion of invasive breast cancer. In recent decades the incidence of DCIS has risen continuously, mainly because of more extensive screening and more advanced diagnostic procedures. There is an increasing need for evidence-based treatment guidelines which will protect patients as far as possible from recurrence or invasive cancer but also from overtreatment. This retrospective single-center clinical trial analyzed recurrence-free survival times, rates of invasive and non-invasive events, and the impact of patient history, histopathological variables and therapeutic factors on recurrence-free survival times. Material and Methods: A total of 200 patients who underwent surgery between 2000 and 2007 for pure DCIS were included in the study. As part of follow-up a questionnaire was sent to patients and their respective gynecologists. Results: In the follow-up period, 12.5â% (n = 25) of the 200 patients had recurrence (invasive or non-invasive event). Menopausal status, tumor grade and tumor size were significantly associated with recurrence. Low-grade DCIS was significantly more often hormone receptor-positive than high-grade DCIS. Patients who had postoperative radiotherapy significantly more often also received endocrine drug treatment. There was a significant association between younger patient age and drug treatment. The study found that in the investigated cohort, premenopausal women had a significantly shorter recurrence-free time compared to postmenopausal women. Conclusion: This paper summarizes the current literature on DCIS. There is a need for more prospective clinical trials to improve the prognosis of premenopausal women with large and hormone receptor-positive DCIS.
RESUMO
Endometriosis is the second most common benign female genital disease after uterine myoma. This review discusses the interdisciplinary approach to the treatment of deep infiltrating endometriosis. Endometriosis has been defined as the presence of endometrial glands and stroma outside the internal epithelial lining of the cavum uteri. As a consequence, endometriosis can cause a wide range of symptoms such as chronic pelvic pain, subfertility, dysmenorrhea, deep dyspareunia, cyclical bowel or bladder symptoms (e.g., dyschezia, bloating, constipation, rectal bleeding, diarrhoea and hematuria), abnormal menstrual bleeding, chronic fatigue or low back pain. Approx. 50â% of teenagers and up to 32â% of women of reproductive age, operated for chronic pelvic pain or dysmenorrhoea, suffer from endometriosis. The time interval between the first unspecific symptoms and the medical diagnosis of endometriosis is about 7 years. This is caused not only by the non-specific nature of the symptoms but also by the frequent lack of awareness on the part of the cooperating disciplines with which the patients have first contact. As the pathogenesis of endometriosis is not clearly understood, a causal treatment is still impossible. Treatment options include expectant management, analgesia, hormonal medical therapy, surgical intervention and the combination of medical treatment before and/or after surgery. The correct treatment for each patient should take into account the severity of the disease and whether the patient desires to have children. The treatment should be as radical as necessary and as minimal as possible. The recurrence rate among treated patients lies between 5 and > 60â% and is very much dependent on the integrated management and surgical skills of the respective hospital. Consequently, to optimise the individual patient's treatment, a high degree of interdisciplinary cooperation in diagnosis and treatment is crucial and should, especially in the case of deep infiltrating endometriosis, be undertaken in appropriate centres.

OBJECTIVES: Is the saliva test, Geratherm ovu control, as accurate as the established urinary luteinizing hormone (LH) test for detecting ovulation and the following the fertile period? STUDY DESIGN: The voluntary participants were 74 healthy women with regular menstrual cycles and not using any hormonal contraceptives. The women used Geratherm ovu control, a small plastic hand-held microscope, for detecting the fertile period. A drop of saliva from sublingual was put onto the lens of the microscope. Three results were possible: non-fertile (dot pattern), transitional and fertile (ferning pattern). The participants performed the saliva test from the 5th till the 22nd day of the menstrual cycle and noted the respective result in a table. In addition to Geratherm ovu control, the EXACTO test for determining urinary LH concentration and the time of peak fertility was also performed. RESULTS: Positive LH shows a sharp increase beginning on the 10th cycle day with a maximum on the 17th cycle day. The curve for positive saliva and questionable positive saliva (one curve) is almost parallel with the curve for positive LH, reaching a maximum on the 16th cycle day. There is a high level of conformity for the same test results from the 5th (100%) till the 14th (84%) cycle day and from the 18th (80%) till the 22nd (96%) cycle day which corresponds to the pre- and post-ovulatory period. CONCLUSION: The saliva and the LH test both detect the fertile window of a menstrual cycle. Caused by the different hormones (estrogen for the saliva and LH for the LH test) leading to the respective positive test results, saliva turns positive 24h before LH. Consequently, the saliva test can be used as an ovulation test and help women maximize their chances of conceiving. There is also a high congruence between LH and saliva in the pre- and post-ovulatory period, indicating that the saliva test can also be used for contraception purposes.

Neuroendocrine neoplasms (NEN) of the breast are specific tumor entities. According to the literature up to 5% of breast neoplasms are malignant epithelial neoplasms of the breast. They are defined by a neuroendocrine (NE) architecture and cytology combined with an expression of the neuroendocrine vesicle markers chromogranin A and/or synaptophysin. The diagnosis is supplemented by the receptor status and the proliferative activity. According to the World Health Organization (WHO) classification of 2012 the following groups of NEN are distinguished: (1) invasive breast carcinoma with NE differentiation, (2) well-differentiated neuroendocrine tumor (NET) and (3) poorly differentiated small cell carcinoma (NEC). This review article focuses on (1) the definition and basic principles of diagnostics, (2) the history, nomenclature and WHO classification from 2003 and 2012, (3) the frequency of breast NEN, (4) the hereditary background and functional activity, (5) the expression of receptors and (6) the possible clinical implications. In addition, the first results of a retrospective single center study (n = 465 patients with breast cancer over a time period of 4 years) on the frequency of NEN of the breast at the Breast Center of the University Hospital Düsseldorf are presented. In this study a frequency of 4.5% of NEN was found based on a diagnostic cut-off of > 50% Chromogranin A and/or synaptophysin positive tumor cells.

OBJECTIVES: For patients undergoing vulva surgery the quality of life (QoL) is generally accepted as an important outcome parameter in addition to long-term survival, mortality and complication rates. Less radical operative treatment can reduce morbidity and thereby improve quality of life. This study focuses on outcome in terms of QoL in patients comparing wide local excision (WLE) with radical vulvectomy and waiver of lymphonodectomy (LNE) with inguinofemoral lymphonodectomy. METHODS: In a retrospective single-center study from 2000 to 2010, 199 patients underwent surgery for vulvar cancer. To assess QoL, the EORTC QLQ-C30 and a tumor-specific module questionnaire were sent to all patients in the follow-up period. RESULTS: Women who underwent WLE have a superior QoL with regard to global health status and physical, role, emotional and cognitive functioning than those who underwent radical vulvectomy. Less radical surgery also implies less fatigue, nausea/vomiting, pain, insomnia, appetite loss, diarrhea and financial difficulties. After radical vulvectomy 89% of patients have sexual complications. CONCLUSION: Radical operative treatment, such as radical vulvectomy, causes deterioration in the QoL of these patients. An individualized, less radical surgery must be the aim in the treatment of vulvar cancer.

BACKGROUND/AIMS: The new mini-microscope Geratherm® ovu control was evaluated for its recognition of saliva ferning in a collective of 47 patients taking part in an artificial reproductive technology program on the day of follicular puncture. METHODS: The ferning phenomenon was evaluated by patients and laboratory staff according to the criteria: no ferning, slight ferning and good ferning. RESULTS: Geratherm® ovu control showed a specificity of 78% and a sensitivity of 80% in relation to rising E2 levels under follicle-stimulating hormone/human chorionic gonadotrophin. A comparison of the evaluations of the saliva test carried out by patients and by laboratory staff resulted in a high and substantial agreement of 89.4% (κ). CONCLUSION: Evaluations performed by ovu control were similar to those achieved with a highly sophisticated inverted microscope.

Local treatment of breast cancer with tumor-free surgical margins is the standard procedure in the treatment of T1 and small T2 breast cancers. Surgery is followed by radiation therapy, and adjuvant systemic therapy is offered depending on primary tumor characteristics, such as tumor size, grade of differentiation, number of involved axillary lymph nodes, the status of estrogen (ER) and progesterone (PR) receptors, and the expression of the human epidermal growth factor 2 (HER2) receptor. Although this approach implies a higher risk of ipsilateral breast tumor recurrence, the total risk of recurrence is low (1% per year), with rates of overall survival similar to that after radical procedures. The most peripheral part of epithelial tumors, the tumor margin, is the part which is most likely to remain in loco after surgical resection. Thus, understanding the biology of the invasion front is important as these tumor cells have been reported to lose epithelial properties, such as cohesiveness and keratin expression, and to acquire features of mesenchymal cells. The parallel appearance of tumor cells in different states of cell dedifferentiation implicates a dynamic equilibrium that is determined by the induction of epithelial-mesenchymal transition (EMT). EMT has been suggested to be of prime importance for tissue and vessel invasion. Furthermore, features of EMT are associated with the activity of tumor stem cells (TSC). TSC exist in breast cancer and their appearance varies depending on the used marker profile. Consequently, intratumoral heterogeneity is reflected by the grade of EMT activation. A specific function at the invasion front is hypothesized but has not yet been proven. Nevertheless, the molecular differentiation between the tumor center and the invasion front enhances the importance of tumor-free surgical margins.

Malignant melanoma of the urethra is a rare tumour that is difficult to diagnose and treat, resulting in a poor prognosis. In this paper, we present the case of a 65-year-old woman who was referred to a gynaecologist because of a urethral mass that mimicked a caruncle. The tumour was removed by local excision, and a pathological analysis revealed a malignant melanoma. Distal urethrectomy was performed after three months with no evidence of residual tumour. There was no evidence of disease at a six-year followup. In this paper, we compare the epidemiology, treatment, staging, and prognosis of vulvar cancer in general to malignant melanoma of the vulva in particular.
RESUMO
The aim of this study was to compare vacuum and conventional dressings and to follow revascularization with laser-Doppler spectroscopy and histological evaluations. In six minipigs, full thickness skin grafts were harvested on both sides of the back and transplanted to the contralateral site. One site was covered with a classical cotton dressing, the other with a vacuum dressing. For 10 days, oxygen, haemoglobin, flow and velocity levels were measured by laser-Doppler spectroscopy. Data were analyzed with ANOVA. Histological evaluation included haematoxylin and eosin (H&E) as well as CD31 immunohistochemical staining. Oxygen levels were significantly reduced in the vacuum dressing group compared with the classic dressing group during the first 3 days after transplantation. Haemoglobin levels were slightly, but significantly, higher in the vacuum dressing group over the whole observation period. On the second and third day after transplantation single capillaries were detectable in the histological evaluation. Starting from the fourth day, capillary number increased. Similar results for the classical pressure dressing and the vacuum dressing were observed. The present experimental model provides a standardized and reliable test system for evaluating revascularization of full thickness skin grafts in conjunction with growth factors and other enhancers of revascularization.

Immunosuppression with subsequent opportunistic infections is a well-recognized complication of severe hypercortisolism. We report a case of fatal pneumocystis jirovecii pneumonia (formerly pneumocystis carinii pneumonia) in a case of ectopic Cushing's syndrome caused by a neuroendocrine carcinoma of the kidney. The 36-year old male patient had consulted a physician because of weight gain. Further endocrine diagnostic work-up revealed ACTH-dependent hypercortisolism of non-pituitary origin. Because of rapid clinical deterioration therapy with metyrapone was initiated. A neuroendocrine carcinoma of the right kidney with regional lymph node infiltration was identified and was suspected to be the source of the ACTH excess. Before any causal therapy could be initiated, the patient developed severe pneumocystis jirovecii pneumonia and died shortly thereafter from multiorgan failure one month after he first consulted a physician. Pneumocystosis has been reported in only a few cases of Cushing's syndrome. There seems to be a relationship between the degree of hypercortisolism and the susceptibility to opportunistic infections. Since ACTH concentrations may be excessively high in ectopic Cushing's syndrome and pneumocystosis may deteriorate as a consequence of decreasing circulating cortisol levels under adrenolytic therapy, prophylaxis against pneumocystis jirovecii infection should be considered.
