OBJECTIVE:
To evaluate the clinical effect of acellular dermal matrix (ADM) on the repair of different tissue defects in pharyngeal and laryngeal cancer.
METHOD:
Twenty-three cases of pharyngeal and laryngeal cancer were analyzed retrospectively, including 16 patients with pharyngeal cancer, and 7 patients with laryngeal cancer. After surgery, the patients appeared two types of tissue defects respectively: hypopharynx tissue defect and neck skin tissue defect. These defects were repaired with ADM, and the clinical effects were observed.
RESULT:
Sixteen cases of hypopharynx tissue defect and 7 cases of neck skin tissue defect were repaired with ADM. One case in hypopharynx tissue defect group and 2 cases in neck skin tissue defect group undergone pharyngeal fistula postoperatively.
CONCLUSION
The repair of tissue defects in pharyngeal and laryngeal cancer with ADM had some advantages, such as good histocompatibility, low immune rejection, wide material sources and simple method. There were some differences in clinical effects between hypopharynx cavity defect and neck skin tissue defects, so the emphasis of the need to pay attention to is different in the clinical.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2015;29(11):963-966
OBJECTIVE:
To compare the clinical results between stapled and traditional suture closure total laryngectomy.
METHOD:
Fifty-three cases of laryngeal cancer with total laryngectomy were divided into 2 groups: 32 cases with traditional suture closure total laryngectomy (group A) and 21 cases with stapled total laryngectomy group (group B). Compare two groups in pharyngeal fistula, postoperative bleeding, dysphagia, and nasal regurgitation.
RESULT:
There was no difference of postoperative pharyngeal fistula between group A and B (P>0. 05). The incidence of dysphagia, nasal regurgitation, and postoperative bleeding in group B were 23. 8%, 14. 3% and 14. 3% respectively, which were obviously higher than that in group A (P<0. 05).
CONCLUSION
Stapled total laryngectomy has the advantages of reducing the operative time and simplifying the operation with some disadvantages such as higher standards of operation indications, higher incidence of dysphagia, higher nasal regurgitation, higher postoperative bleeding, and poor medical economic profit. Traditional suture closure total laryngectomy is recommended in clinical practice.

The paper describes the significance of clinical pathological congresses in clinical work. It argues that at present there is the tendency of laying stress on modern advanced diagnostic means at the expense of basic physical diagnostic means and traditional therapies, and traditional conduction of clinical pathological congresses for the purpose of summarizing medical experience and promoting medical advancement has even become a rarity, which is very harmful to the cultivation of qualified clinical doctors. The paper gives an account of how the authors' hospital encouraged performance of autopsies and persisted in holding clinical pathological congresses. Its experience is that clinical pathological congresses have many functions in clinical work, including solving knotty problems like multidisciplinary and multisystematic pathological changes by drawing upon all useful opinions; exchanging information, which is beneficial to doctors learning from one another and making common progress; cultivating personnel via tempering young doctors and updating senior doctors'knowledge; and strengthening the hospital's cohesive force.

Objective To provide a reliable differential diagnosis among the progressive supranuclear palsy ( PSP), striatonigral degeneration ( SND ) and Parkinson disease ( PD ) . Methods Conventional MRI data in clinically proved PSP(8 cases), SND(9 cases), PI)( 12 cases)and 12 normal controls were retrospectively analyzed. Midbrain area, pons area, ports diameter and middle eerebellar peduncles width were measured. The ratio of pons area over midbrain area (pons area/midbrain area) was calculated in all patients and normal controls. Then one way ANOVA and a Kruskal-Wallis H test were used for statistical analysis. Results Midbrain area of the PSP group [ (85. 8±12. 0) mm2 ] was the smallest, and there was statistically significant difference ( P < 0. 05 ) comparing with the SND group [ ( 133.2± 8. 4) nun2 ], PD group[ ( 133. 5±10. 8) mm2 ] and the control group [ ( 135.9±7.5 ) mm2 ]. There was no overlapping in the distribution of midbrain area between the PSP group(66.0-98. 2 mm2 ) and SND, PD and normal groups( 116. 2-142. 1, 110. 8-146. 2 and 121.7-145.8 mm2 ). The pons area-midbrain area ratio (P/M) of the PSP group (5.9±0. 8) was the largest in four groups, and there was statistically significant difference ( P < 0. 05 ) comparing with the SN D group ( 2. 9±0. 5 ), PD group ( 3.8±0. 3 ) and the control group (3. 8±0. 3 ). There was no overlapping in the distribution of P/M between the PSP group(5.0-7.2) and SND,PD and normal groups(2. 2-3.5, 3. 3-4. 6 and 3. 2-4. 2). SND group had the smallest P/M, pens area, pons diameter and middle cerebellar peduncles width [ 2.9±0. 5, ( 384. 8±62. 6) mm2 , ( 18. 6±2. 0) nun and( 12. 9±2. 4) mm ] in all groups, and significant difference ( P < 0. 05 ) was found comparing with the PSP group[5.9±0. 8, (500.1±21.8)mm2, (22. 7±1.7)mm and( 16. 3±1. 1) nun],PD group[3.8±0.3, (500.2±25.8)mm2, (23.7±1.0)mm and(16.8±1. 1)mm]and the control group [3. 8±0. 3, ( 508. 8±20. 6 ) mm2, ( 23.2±1.2) nun and ( 16. 4±0. 9 ) mm]. But the PD group and control group had no statistically significant difference in the midbrain area, pans area, pons diameter, P/M and middle cerebellar peduncles width ( P > 0. 05 ). Conclusion MRI measurements helps in the differential diagnosis among PSP, SND and PD.
