RN Braun observed that frequencies of health disorders in general practice are so consistent that he called his discovery "Case Distribution Law". Our study compares morbidity data from methodologically similar surveys in primary care practices over a period of fifty years. Frequency ranks were determined for each observation period and the first 150 ranks were compared with Spearman's correlation coefficients. All correlations were consistently positive. Frequency ranks were strikingly similar for surveys carried out at approximately the same time, especially when nomenclatural matching had been carried out before data collection. Ranks were also very similar where clear disease classifications were possible, but less so for non-specific symptoms.The consistency of the distribution of health disorders helps develop diagnostic strategies (diagnostic protocols) and appropriate labeling for non-specific, diagnostically open symptom classifications. According to Braun's considerations, the regularity of case distribution plays an important role in the professionalization of primary care.

Clinicians face significant diagnostic challenges when dealing with nodal lesions of the lung. The majority of lung nodules are benign; however, a significant number can be cancerous. Dirofilaria infestation should also be considered in the differential diagnosis of nodal lung lesions. Most patients with Dirofilaria infestation are asymptomatic. To determine the etiology of nodal lung infiltrations, procedures like radiological imaging, bronchoscopy, endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA), transthoracic biopsy (TTB), tumor markers, nonspecific serological tests, or surgical removal of the lung coin lesions can be performed. Coil marking of the smaller lung lesions under computed tomography (CT) guidance is a helpful tool in determining the position and localization of the nodal lung lesions. Video-assisted thoracoscopic surgery (VATS) or robot-assisted thoracoscopic surgery (RATS) wedge resection is a diagnostic and therapeutic method of choice. No additional treatment of Dirofilaria other than wedge resection of the lung is necessary.

Objective: This study aimed to discuss the application value of an artificial intelligence-based diagnosis and recognition system (AIDRS) in the teaching activities for Bachelor of Medicine and Bachelor of Surgery (MBBS) in China. The learning performance of graduate students in gastroenterology during gastroscopy training with and without AIDRS was assessed.

Methods: The study recruited 32 graduate students of the gastroenterology program at Jiangsu province hospital of Chinese medicine and Xiangyang No. 1 People's Hospital from March 2018 to March 2022 and randomly divided them into AIDRS (n = 16) and non-AIDRS (n = 16) groups. The AIDRS software was used for real-time monitoring of blind spots of gastroscopy to aid in lesion diagnosis and recognition in the AIDRS group. Only a conventional gastroscopic procedure was implemented in the non-AIDRS group. The final performance score, success rate of gastroscopy, lesion detection rate, and pain score of patients were compared between the two groups during gastroscopy. A self-prepared teaching and learning satisfaction questionnaire was administered to the two groups of students.

Results: The AIDRS group had a higher final performance score (92.60 ± 2.83 vs. 89.21 ± 3.57, t = 2.98, P < 0.05), a higher success rate of gastroscopy (448/480 vs. 417/480, χ² = 11.23, P < 0.05), and a higher detection rate of lesions (51/52 vs. 41/53, χ² = 8.56, P < 0.05) compared with the non-AIDRS group. The pain scores of patients were lower in the AIDRS group than in the non-AIDRS group (3.40 [2.23, 3.98] vs. 4.45 [3.72, 4.75], Z = 3.04, P < 0.05). Besides, the average time for gastroscopy was lower in the AIDRS group than in the non-AIDRS group (7.15 ± 1.24 vs. 8.21 ± 1.26, t = 2.38, P = 0.02). The overall satisfaction level with the teaching program was higher in the AIDRS group (43.51 ± 2.29 vs. 40.93 ± 2.07, t = 3.33, P < 0.05).

Conclusion: In the context of medicine-education cooperation, AIDRS offered valuable assistance in gastroscopy training and increased the success rate of gastroscopy and teaching and learning satisfaction. AIDRS is worthy of wider-scale promotion.

In Germany, non-medical practitioners (NMPs; in German: Heilpraktiker) offer a broad range of complementary and alternative (CAM) methods. Our aim was to characterize schools for NMPs in Germany in terms of basic (medical) training and advanced education. We found 165 schools for NMPs in a systematic web-based search. As the medical board examination NMPs must take before building a practice exclusively tests their knowledge in conventional medicine, schools hardly include training in CAM methods. Only few schools offered education on CAM methods in their NMP training. Although NMP associations framed requirements for NMP education, 83.0% (137/165) of schools did not meet these requirements. Patients and physicians should be aware of the lack of training and consequent risks, such as harm to the body, delay of necessary treatment, and interaction with conventional drugs. Disestablishing the profession of NMPs might be a reasonable step.

Introduction: We reviewed 63 reports from the literature on rare non-serous tumors of the fallopian tubes and carried out a comparative analysis of clinical manifestations and diagnostic methods. We also report our observations from patients with these tumors.

Materials and methods: Of 157 patients with primary fallopian tube cancer (FTC) treated in our regional oncological hospital between 1970 and 2020, there were nine (6%) cases of rare non-serous cancers, including one case each of choriocarcinoma, carcinosarcoma, and neuroendocrine tumor, and two cases each of non-keratinizing squamous cell carcinoma, mucinous adenocarcinoma, and clear cell adenocarcinoma.

Results: For carcinosarcoma and squamous cell, clear cell, and transitional cell carcinomas, clinical history, patient age, and clinical manifestations were similar to the main group of FTCs. Choriocarcinoma differed significantly from other cancers of the fallopian tubes in terms of patient age and clinical course. Mucinous adenocarcinoma, mesothelioma, and borderline tumors, with rare exceptions, were almost always asymptomatic and were found only incidentally during surgery. Choriocarcinoma and carcinosarcoma had an aggressive course, while squamous cell, transitional cell, clear cell, and mucinous carcinomas were less aggressive. Since most rare non-serous tumors have a similar disease course to typical FTCs and there is a lack of appropriate treatment protocols for rare tumors, treatment options developed for ovarian tumors and FTC are justified for these tumors.

Conclusion: Rare non-serous malignant fallopian tube tumors are very similar to serous and endometrioid FTC in terms of clinical manifestations and diagnosis.

Background: This study aimed to evaluate plasma relaxin‑2 (RLN-2) levels in patients with arterial hypertension (AH) and their relationships with clinical and laboratory parameters.

Methods: The study involved 106 hypertensive patients, including 55 with type 2 diabetes mellitus (T2DM), and 30 control subjects. Plasma RLN-2 levels were measured using an enzyme-linked immunosorbent assay kit.

Results: RLN-2 levels were reduced in patients with AH compared to healthy volunteers (p < 0.001), and hypertensive patients with T2DM had lower RLN-2 levels than those without impaired glucose metabolism (p < 0.001). RLN‑2 was negatively correlated with systolic blood pressure (SBP) (p < 0.001) and anthropometric parameters such as body mass index (BMI; p = 0.027), neck (p = 0.045) and waist (p = 0.003) circumferences, and waist-to-hip ratio (p = 0.011). RLN‑2 also had inverse associations with uric acid levels (p = 0.019) and lipid profile parameters, particularly triglycerides (p < 0.001) and non-HDL-C/HDL‑C (p < 0.001), and a positive relationship with HDL‑C (p < 0.001). RLN‑2 was negatively associated with glucose (p < 0.001), insulin (p = 0.043), HbA1c (p < 0.001), and HOMA-IR index (p < 0.001). Univariate binary logistic regression identified RLN‑2 as a significant predictor of impaired glucose metabolism (p < 0.001).

Conclusions: Decreased RLN-2 levels in patients with AH and T2DM and established relationships of RLN‑2 with SBP and parameters of glucose metabolism and lipid profile suggest a diagnostic role of RLN‑2 as a biomarker for AH with T2DM.

In recent years, utilization of emergency departments (EDs) has increased continuously, both in Germany and internationally. Inappropriate use of EDs is believed to be partly responsible for this trend. The topic of doctor-patient interaction (DPI) has received little attention in research. However, successful DPI is not only important for adherence and treatment success, but also for the satisfaction of medical staff. This non-interventionl cross-sectional study attempts to identify factors influencing physicians' satisfaction with DPIs, with a particular focus on the appropriate utilization of EDs and verbal communication. We carried out tripartite data collection in three EDs of major referral hospitals in Berlin between July 2017 and July 2018. Migration experience, communication and language problems, level of education, and a large gap between physicians' and patients' perceived urgency regarding the utilization of EDs influence the quality of the doctor-patient relationships and interactions.

Preanaesthesia consultation is performed to assess and optimise patient-specific risk factors before surgery, to inform patients about anaesthesia techniques and to obtain consent. Aside from face-to-face visits, telephone consultation is increasingly being used clinically. Concentration on the content and avoidance of confounding factors could lead to improved patient preparation. We hypothesised that patients receiving a telemedical intervention have less anxiety. Patients scheduled for elective surgery were randomised into two groups according to the consultation performed face-to-face (FTF) or via telephone (TEL). Before consultation (< 48 h) and 1-2 h prior to surgery, both groups had to fill in the State-Trait Anxiety Inventory (STAI). A total of 271 patients were randomised and 130 were analysed. There were no significant intergroup differences in mean state anxiety (STAI-S) before and after the intervention. Patients' positive feedback on telemedical consultation urges future studies on its effect on satisfaction and quality of life.

Medical communication is an effective instrument for the medical practice. Due to the low status that medical communication still has within medicine and medical education, many physicians do not know how to use this instrument professionally. Using medical communication in a way that patients are well informed and involved is a prerequisite for them to make self-determined decisions. In this paper I analyze a consultation in an oncology ward to show the pitfalls of medical communication, especially in triadic communication, based on a case study to work out suggestions for optimization from the transcript. Mistakes in conducting conversations, which can be recognized as such in theory, unfortunately still happen in practice, which is why this case study is intended as an invitation to critically reflect on one's own conduct of conversations. The conclusion contains suggestions for the preparation as well as the conduct of the consultation during medical rounds.

We represent the case of a premature twin neonate born from uncomplicated pregnancy who developed seizures at the age of 24 h. Two-dimensional ultrasound and magnetic resonance imaging revealed left-sided hemimegalencephaly. Further extensive diagnostic evaluation revealed a diagnosis of Ohtahara syndrome. Resistance of the seizures to antiepileptic therapy led to hemispherotomy that was performed at the age of 10 months. Our patient is now a 4-year-old child, walking, eating without a nasogastric tube, still with right hemiparesis and lateral strabismus but without seizures.
