The number of new cases of hypophyseal tumor increases along with the advances in neuroimaging technology in recent years. The common treatment models include surgical treatment, radiotherapy, and medical therapies. This article discusses the application of long-term follow-up in non-operative hypophyseal tumor patients and its influence on the prognosis. Meanwhile, since the medical mode has switched from biomedical model to biopsychosocial medical model, management of hypophyseal tumor should not be limited in its biological aspect, but also from the perspective of psychology by providing more humanistic care to meet the patients'psychological needs.

OBJECTIVETo analyze the causes of misdiagnosis of primary hypothyroidism (PH), with an attempt to reduce the misdiagnosis or mistreatment.

METHODSTotally 70 PH children with a history of misdiagnosis but whose conditions were confirmed in Peking Union Medical College Hospital and the First Hospital of Jilin University from July 2000 to May 2009 were enrolled in this study. The clinical data were collected and the causes of misdiagnoses were analyzed.

RESULTSOf these 70 patients, 19 were misdiagnosed as anaemia and dystrophy, 18 as pituitary tumors, 10 as adiposities, 6 as myocarditis or pericardial effusion, 4 as Downs syndrome, 3 as hepatitis, 3 as amyasthenia, 3 as cerebral palsy, 2 as cystis thyrolingualis, and 2 as congenital megacolon. The duration of misdiagnoses ranged from 6 to 72 months. The clinical manifestations of these patients were complicated, involving multiple organs and systems.

CONCLUSIONSPH has complicated clinical manifestations and individual variations, and therefore can be easily misdiagnosed. Good knowledge, sufficient history-taking, and cautious physical examinations can help avoid misdiagnosis. Neonatal screening is helpful for diagnosis and treatment of congenital hypothyroidism.

Objective To investigate the efficacy and safety of endovascular therapy for small unruptured intracranial aneurysms (sUIAs). Methods Patients with unruptured intracranial aneurysms who underwent endovascular therapy in the Department of Neurology, Guangzhou First People's Hospital from January 2008 to January 2018 were retrospectively included. According to the size of the aneurysms, they were divided into the sUIAs group (diameter <5 mm) and the non-sUIAs group (diameter ≥5 mm). Demographics, vascular risk factors, aneurysm characteristics, and treatment method, effectiveness, perioperative complications, and outcomes of endovascular therapy were compared between the two groups. Results A total of 80 patients with unruptured intracranial aneurysms were enrolled, including 33 patients with sUIAs (41.25% ) and 47 patients with non-sUIAs. The age of patients (51.1 ± 9.7 years vs. 61.2 ± 8.1 years; t=5.058, P<0.001), and the maximum diameter (3.6 ± 1.1 mm vs. 8.2 ± 3.2 mm; t=7.923, P<0.001) and neck width (3.1 ± 0.5 mm vs. 4.5 ± 2.5 mm; t=3.167, P=0.002) of aneurysms as well as the proportion of patients with wide-neck aneurysm (3.0% vs. 21.3% ; χ2 =7.213, P=0.007) and stent-assisted embolization (6.1% vs. 23.4% ; χ2 =4.285, P=0.038) in the sUIA group were significantly less than those of the non-sUIAs group. The embolization results, the perioperative complication rate and the good outcome rate were comparable between the two groups. Conclusion For sUIAs, endovascular therapy is effective and safe, comparable to endovascular therapy for non-sUIAs.

Objective To investigate clinical and epidemiological features of pneumocystis jirovecii pneumonia (PJP) in kidney transplant recipients. Methods Clinical data of 68 kidney transplant recipients admitted from July, 2021 to December, 2021 were collected. All patients were divided into the PJP group (n=11), common pulmonary infection group (n=24) and non-pneumonia group (n=33) according to the status of pulmonary infection. The incidence and treatment of PJP after kidney transplantation were analyzed. Basic characteristics and laboratory parameters of the recipients were compared among all groups. The genotyping and transmission map of PJP patients were evaluated. Results Among 64 kidney transplant recipients, 11 cases were definitely diagnosed with PJP. The most common clinical manifestations included elevated body temperature, and dry cough complicated with progressive dyspnea. Chest CT scan showed diffuse interstitial inflammation and ground glass-like lesions of bilateral lungs in all patients. After diagnosis, all patients were orally given with compound sulfamethoxazole for 3-4 weeks. Two patients received non-invasive ventilator-assisted ventilation due to severe lung infection and dyspnea, and the remaining patients were given with nasal cannula oxygenation. One patient experienced elevated serum creatinine level upon discharge, and developed renal allograft failure. The remaining 10 recipients with PJP obtained normal renal allograft function, and no recipient died. Compared with the non-pneumonia group, the rejection rate was higher, the length of hospital stay was longer, the lymphocyte count was less, the lymphocyte proportion was lower, the levels of C-reactive protein, serum creatinine and lactate dehydrogenase were higher, and the levels of serum albumin was lower and CD4⁺T cell count was less in the PJP group (all P < 0.05). Compared with common pulmonary infection group, the lymphocyte count was less, the lymphocyte proportion was lower, the CD4⁺T cell count was less and 1, 3-β-D- glucan (BDG) level was higher in the PJP group (all P < 0.05). No new genotype was detected in 10 of the 12 testing samples. It was considered that PJP mainly depended on two transmission chains and two independent transmission individuals. Conclusions Kidney transplant recipients are prone to pneumocystis jirovecii (PJ) infection due to impaired cellular immune function. The most common clinical manifestations consist of elevated body temperature and dry cough complicated with progressive dyspnea, accompanied by headache and fatigue in partial patients. Chest CT scan shows diffuse interstitial inflammation and ground glass-like lesion of bilateral lungs. PJ may be transmitted through respiratory tract. Small-scale PJP might occur in the follow-up outpatient of kidney transplant recipients. Preventive measures should be delivered in a timely manner.
