\u3cem\u3eMesobuthus zarudnyi\u3c/em\u3e sp. n. from Azerbaijan (Scorpiones: Buthidae)
A new species Mesobuthus zarudnyi sp. n. is described from Azerbaijan, fully illustrated with color photos. We compare the new species with two other species, M. eupeus (C. L. Koch, 1839) and M. persicus (Pocock, 1899), both found also in Azerbaijan
A revision of the genus Mesobuthus Vachon, 1950, with a description of 14 new species (Scorpiones: Buthidae)
The Asian genus Mesobuthus Vachon, 1950, s. str. (Buthidae) (also known as an informal M. eupeus complex), which includes the most common scorpion species found from Turkey to China, is revised based on new collections, mainly from Central Asia, Turkey, and Iran, using both morphological and mitochondrial DNA data. Available type specimens of all species were studied; neotypes and lectotypes were designated when necessary. The type species Mesobuthus eupeus (C. L. Koch, 1839), s. str., is restricted to the Caucasus Mts. Currently, the genus includes 29 valid species. Fifteen previously described taxa are recognized as species: Mesobuthus afghanus (Pocock, 1889) (Afghanistan, Iran, Turkmenistan) (= ?Buthus agnetis Werner, 1936, syn. n.), M. barszczevskii (Birula, 1904), stat. n.

Diagnostic performance and clinical impact of Ga-68-PSMA-11 PET/CT imaging in early relapsed prostate cancer after radical therapy: a prospective multicenter study (IAEA-PSMA study)
Biochemical recurrence (BCR) is a clinical challenge in prostate cancer (PCa) patients, as recurrence localization guides subsequent therapies. The use of PET with prostate-specific membrane antigen (PSMA) provides better accuracy than conventional imaging practice. This prospective, multicenter, international study was performed to evaluate the diagnostic performance and clinical impact of PSMA PET/CT for evaluating BCR in PCa patients in a worldwide scenario. METHODS : Patients were recruited from 17 centers in 15 countries. Inclusion criteria were histopathologically proven prostate adenocarcinoma, previous primary treatment, clinically established BCR, and negative conventional imaging (CT plus bone scintigraphy) and MRI results for patients with PSA levels of 4-10 ng/mL. All patients underwent PET/CT scanning with 68Ga-PSMA-11. Images and data were centrally reviewed. Multivariate logistic regression analysis was applied to identify the independent predictors of PSMA-positive results. Variables were selected for this regression model on the basis of significant associations in the univariate analysis and previous clinical knowledge: Gleason score, the PSA level at the time of the PET scan, PSA doubling time, and primary treatment strategy. All patients were monitored for a minimum of 6 mo. RESULTS : From a total of 1,004 patients, 77.7% were treated initially with radical prostatectomy and 22.3% were treated with radiotherapy. Overall, 65.1% had positive PSMA PET/CT results. PSMA PET/CT positivity was correlated with the Gleason score, PSA level at the time of the PET scan, PSA doubling time, and radiotherapy as the primary treatment (P < 0.001). Treatment was modified on the basis of PSMA PET/CT results in 56.8% of patients. PSMA PET/CT positivity rates were consistent and not statistically different among countries with different incomes. CONCLUSION : This multicenter, international, prospective trial of PSMA PET/CT confirmed its capability for detecting local and metastatic recurrence in most PCa patients in the setting of BCR. PSMA PET/CT positivity was correlated with the Gleason score, PSA level at the time of the PET scan, PSA doubling time, and radiotherapy as the primary treatment. PSMA PET/CT results led to changes in therapeutic management in more than half of the cohort. The study demonstrated the reliability and worldwide feasibility of PSMA PET/CT in the workup of PCa patients with BCR.Partially funded by IAEA.https://jnm.snmjournals.orghj2023Nuclear Medicin

Хірургічне лікування хворих з приводу множинних прогресуючих об’ємних утворень головного мозку різної етіології
The results of surgical treatment of 220 patients with multiple poliethiological progressing cerebral volume formations, been hospitalized in a neurosurgical clinic at period from 1985 to 2007, are presented. The final and reliable diagnosis was set on the basis of disease clinical signs’ comparison with CT and MRI data. At 40 patients meningiomas were found out, at 24 — intracerebral gliomas, at 26 — metastasis, at 56 — abscesses, at 26 — echinococcus, at 19 — chronic subdural haematomas, at 12 — inborn, at 17 — acquired arachnoid cysts.At meningiomas, gliomas and metastatic tumors method of their simultaneous deleting from one or both brain hemispheres was applied with use of maximally possible vast bone-plastic trepanation. At multiple abscesses the methods of punction aspiration and draining were considered the optimal variants of operative interference. The basic method for echinococcus surgical treatment was parasitic cysts hydraulic extrusion. Favorable result was marked at 186 (84,5%) patients, 34 (15,5%) patients died.Представлены результаты хирургического лечения 220 больных по поводу множественных полиэтиологичных прогрессирующих объемных образований головного мозга, госпитализированных в нейрохирургическую клинику за период 1985–2007 гг. Окончательный и достоверный топико-нозологический диагноз устанавливали на основании сопоставления общеклинических признаков заболевания с данными КТ и МРТ. У 40 больных обнаружены менингиомы, у 24 — внутримозговые глиомы, у 26 — метастатические опухоли, у 56 — абсцессы, у 26 — эхинококкоз, у 19 — хронические субдуральные гематомы, у 12 — врожденные, у 17 — приобретенные арахноидальные кисты.При менингиомах, глиомах и метастатических опухолях применяли методику их одновременного удаления из одного или обоих полушарий большого мозга с использованием максимально дозволенной обширной костно-пластической трепанации.Оптимальными вариантами оперативного вмешательства при множественных абсцессах считали методы пункционной аспирации и дренирования.Основным методом хирургического лечения эхинококкоза явилось гидравлическое выталкивание паразитарных кист. Благоприятный исход отмечен у 186 (84,5%), умерли 34 (15,5%) пациента.Представлені результати хірургічного лікування 220 хворих з приводу множинних поліетіологічних прогресуючих об’ємних утворень головного мозку, госпіталізованих в нейрохірургічну клініку за період 1985–2007 рр. Остаточний і достовірний топіко-нозологічний діагноз встановлювали на підставі зіставлення загальноклінічних ознак захворювання з даними КТ і МРТ. У 40 хворих виявлені менінгіоми, у 24 — внутрішньомозкові гліоми, у 26 — метастатичні пухлини, у 56 — абсцеси, у 26 — ехінококоз, у 19 — хронічні субдуральні гематоми, у 12 — вроджені, у 17 — набуті арахноїдальні кісти.При менінгіомах, гліомах і метастатичних пухлинах застосовували методику їх одночасного видалення з однієї або обох півкуль великого мозку з використанням максимально дозволеної обширної кістково-пластичної трепанації.Оптимальними варіантами оперативного втручання з приводу множинних абсцесів вважали методи пункційної аспірації і дренування.Основним методом хірургічного лікування ехінококозу є гідравлічне виштовхування паразитарних кіст. Сприятливі результати досягнуті у 186 (84,5%), померли 34 (15,5%) пацієнти
